Where to buy</h2>
I decided to buy everything from AliExpress. It's usually cheaper than buying everything where I like (Brazil) and I not in a hurry, which is the bigger disadvantage of AliExpress.
Many of these parts I could easily find in a local store, sometimes even cheaper, but due to the pandemic I don't want to visit any physical store.
With that said, let's go for the list of parts I bought and the individual links (the advantage of buying everything on AliExpress 😄):
Required parts</h2>
It required a lot of reserach to understand what each of these do and why they are required, but here are my choices:
Qty</th> Item</th> Total price</th> BRL (+taxes)</th> Link</th></tr></thead>

68</td> Gateron Brown Sw</td> $ 17.57</td> R$ 109,34</td> AliExpress</a></td></tr>
1</td> Ergodox caps set</td> $ 19.90</td> R$ 123,84</td> AliExpress</a></td></tr>
10</td> RJ9 female</td> $ 5.10</td> R$ 31,73</td> AliExpress</a></td></tr>
50</del></td> M3 Screw 5mm</del></td> $ 1.91</del></td> R$ 11,89</del></td> AliExpress</a></del></td></tr>
25</td> Nut insert M3</td> $ 1.58</td> R$ 9,83</td> AliExpress</a></td></tr>
200</td> IN4148 Diodes</td> $ 1.14</td> R$ 7,09</td> AliExpress</a></td></tr>
2</td> Wrist Rest</td> $ 5.60</td> R$ 34,85</td> AliExpress</a></td></tr>
1</td> Jumper cables</td> $ 0.98</td> R$ 6,10</td> AliExpress</a></td></tr>
3</td> MicroUSB to USBC</td> $ 2.97</td> R$ 18,48</td> AliExpress</a></td></tr>
2</td> RJ9 cables</td> $ 2.24</td> R$ 13,94</td> AliExpress</a></td></tr>
20</td> Reset buttons</td> $ 1.06</td> R$ 6,59</td> AliExpress</a></td></tr>
135</td> Hotswap sockets</td> $ 13.50</td> R$ 84,01</td> AliExpress</a></td></tr>
7</td> Colored wires</td> $ 8.82</td> R$ 54,89*</td> AliExpress</a>**</td></tr>
2</td> Promicro</td> $ 5.90</td> R$ 36,72</td> AliExpress</a></td></tr>
1</td> 2.0% flux solder</td> $ 2.11</td> R$ 11,60</td> AliExpress</a></td></tr> </tbody></table>
update: It turned out the M3 screw is not the right one and the wrong jumper cables were sent 😕.*
Extras:</h3>
Qty</th> Item</th> Price</th> BRL (+taxes)</th> Link</th></tr></thead>

5</td> Testing Switches</td> $ 1.20</td> R$ 7,45</td> AliExpress</a></td></tr> </tbody></table>
I bought so many things and bundled them together that it's now hard to find the exact amount of money I spent considering taxes, currencies, bundled orders, etc. To simplify things a bit I used the average currency exchange from my credit card bill to get all the BRL prices for these items.
This item is open for dispute. For some reason the shipment was cancelled so I'm checking with the seller and didn't get a response.
Cost and ETA</h2>
Currently, it's a total of $92.50 or R$568,35 approximately. I would say R$600 would be a good guess because of the currency exchange flutuation. As a comparison, the minimum wage in Brazil is R$ 1045.
2021 edit: A friend of mine just bought the spare parts I had here for R$100. The final price for the keyboard was ~R$500 (not considering the huge amount of work I'm putting into it, of course 😉).
The average time to get something from AliExpress to Brazil is around 3 weeks and some of these parts started to arrive already 😃
Wait for more about this soon 🚀**

Review of Programming Rust: Fast, Safe Systems Development

Unknown — Tue, 11 Aug 2020 00:00:00 +0000
Book: Programming Rust: Fast, Safe Systems Development</a>. Rating: ⭐️⭐️⭐️⭐️⭐️.
This is a great book for sure. I started reading it in 2017 but never find the time to read it. Now, thanks to having two babies at home, I have enough time to read while waiting for them to sleep. :)
There are many things I like about this book. The first is the comparisons with C and C++ since both authors are/were C/C++ developers. This kind of experience helps you understand how Rust is useful and what practical problems it's actually solving. I always hear about the theory, but the practical examples are gold.
I love the final example where the authors build a wrapper around libgit2 using FFI. It shows how to create a crate that deals with a non-safe interface while building a safe interface for yourself.
The book is a complete and fluid reading for those wanting to understand how Rust works and what you can do by using it.
Here is my raw notes about the book:

Rust infers float if no type was given. It defaults to f64 in case both (f32 and f64) are possible</li>
`std::f32::const</code> define constants for INFINITY</code>, NEG_INFINITY</code>, NAN</code>, MIN</code>, MAX</code>. The same for f64</li>`
`While let pattern = expression</li>`
`Lifetimes for loops. Use 'name_of_lifetime before the loop, so you can use break and continue using this label</li>`
`unwrap_or_else( function)</code> executes the function when there's an error.</li>`
`expect is the same as unwrap but let you define a message in case o fr the 9f a panic</li>`
`The only reasonable use of unwrap is when your function can't fail. E.g. when yiu have a set of data defined but the function you're using to convert returns a result</li>`
`if let = Err(err) is used to unpackage the err tha can be used inside the if block</li>`
`static is a variable created before your program starts. Const is just like C++, it fill be compiled in place to every usage of it</li>`
`debug_assert()</code> and debug_assert_eq()</code> may be used in common code and will not be added in the release</li>`
`If you expect a test to panic, add #[should_panic]</code> attribut to your test</li>`
`Rangefull is the unit-struct for ..</li>`
`Use .. when you don't care about the other fields of the struct in pattern matching</li>`
`If you implement the trait From and you have single argument constructor, you gain into</code> for free</li>`
`By following Rust's strict contract of how to use closures (move, clone, or borrowing),, you gain thread safety</li>`
`Fn trait is implemented by functions and closures. If you define a function and expects an fn only, you will only be able to receive functions, not closures.</li> </ul>`
Assembling an Iris Rev4 Unknown — Thu, 23 Jul 2020 09:48:21 -0300 It's been a while since I'm looking for a keyboard that would be great to take with me when I'm not working from home for some days. I finally found the Iris keyboard that seems to be exactly what I'm looking for. The need</h2> I currently have a Kinesis Advantage at home. The keyboard is great, probably the best keyboard I used so far, but it's far from what we can call portable 😅. I needed a keyboard I could take with me when I wanted, so I started a quest to find it. I bought a typematrix keyboard</a> but it was not good enough (not even mechanical).</li> I had a HHKB Lite</a> but I wanted a mechanical keyboard (it uses rubber dome).</li> I bought a Pok3r</a> keyboard but it was too heavy for what I wanted.</li> I bought an Atreus keyboard</a> but found that a 40% layout was too small for my needs</li> </ul> Then I found the Iris keyboard</a>, which seems to be the perfect size between the Atreus and Kinesis keyboards. The problem is that it's a DIY keyboard and I had zero experience with anything electronic. Talking to some friends I found that the Iris is the easy mode of DIY keyboards, so I decided to give it a try. Pieces and prices</h2> I had to buy the following pieces to be able to do it: 1 x DSA Keycaps</a>: $23.50</li> 5 x Cherry MX Clear Keyswitch (10 pack)</a>: $50</li> 1 x Iris Keyboard - Case/Plates</a>: $27.99</li> 1 x Iris Keyboard - PCBs for Split Ergonomic Keyboard</a>: $59.99</li> 1 x TRRS Cable - Black Coiled</a>: $7.98</li> Shipping costs: $6.10 (keeb.io) + $30 to ship it to Brazil (the final value is R$125 in my local currency)</li> 1 Multimeter: R$37,00</li> 1 Soldering kit (soldering iron, desoldering pump, soldering iron stand, tin wire tube): R$88,00</li> Acrylic Middle layers: $30.00 (bought after the keyboard was assembled as it's optional)</li> </ul> The sum is about $234.60 + R$125,00 (~30 USD). I believe I spent around 280 USD to build the keyboard. In my local currency, using the current conversion (it may have been different when I first bought the needed components), it's around R$1400,00. I had some credits on Amazon and the currency was not that bad at the time. The effective value considering the credits was about R$800,00 which is still almost 4/5 of the minimum wage here in Brazil. Assembling</h2> Again, I would like to mention that I had 0 experience with anything electronic, so it was a amazing how noob I was. :) This was my first soldering. Not something I'm proud of but something I laugh about today. A friend of mine recommended me to use a fan to avoid inhaling the melted tin, so I was doing that. It just took me a while to realize that my fan was actually cooling the tin and the soldering iron making the whole process harder to do. If this is your case, be careful with your fan. It's recommended to first do the soldering for the corner switches so it's easy to change anything in case the position is wrong somehow. I first checked if all the connections for the switches were working correcly. I just used a tweezer to close the connection and get the signal on xev</code>. Keep in mind that the fn</code> keys do not emit any signal and it doesn't mean it's not working. 😉 The four switches were soldered and I did the initia mounting to be sure everything is in place. I'm using brown switches for almost all keys, except the modifiers where I'm using outemu purple switches. It seems like a planned change but I did that to avoid buying another set of switches and a friend (thanks rhruiz!) kindly gave me these outemu purple to complete my set. It's time to insert all switches. Soldering time! The soldering is not great but it's the best I could do on my first attempt. :) The left side is done! Testing all the switches using xev</code> just to be sure the soldering is working (spoiler: it is!) It's time to do the soldering on the right side. Same process. Now that everything is in place, let's add the keycaps. Here it is! The first version is done! 🎉 It's expected that some keys will stop working after adding the keycaps, especially in my case since my soldering skills are not good. I went one by one and found some malfunctioning keys, so it's time to get back to soldering. That's it! Everything done for now and the keyboard is usable already! PS: Here</a> is the album with all pictures I took while assembling the keyboard. 😉 Debugging</h3> At some point I started having some weird behaviors like this "heaven and hell" LEDs: And after some time the keyboard just got disconnected with a yellow LED light: After disconnecting, the keyboad was not responding anymore. No LEDs, no dmesg</code> message or anything. :( I used the multimeter to do some basic continuity tests (thanks for the guidance @rhruiz</a>) but found not short circuit or anything like that. After some time and a RESET while plugged, the keyboard went back to life, showing itself again on dmesg</code>. I saw a dmesg</code> message complaining about the USB cabe and we (me and rhruiz) have a feeling the max brightness on both sides was too much too handle. 🤔 After all of that, the keyboard was reborn and baptized as Telperion: It's important to keep in mind that DIY keyboard will certainly require some sort of maintenance from time to time. This is especially true if it's your first keyboard (as it's mine!) because your soldering may not be the best and it will require some small resoldering fix after some time. Customizing the firmware</h2> The first thing to do is to clone the qmk firmware repository</a>. I suggest forking it and cloning your own fork since you will probably change it. 😉 After cloning the repository, you have to install the software needed to compile and flash the firmware. There are two (maybe more) ways to do that: You can use docker via util/docker_build.sh</code> script. It would be something like: util/docker_build.sh keebio/iris/rev4:default:flash</code></li> You can install all the tools locally via util/qmk_install.sh</code> and flash with make keebio/iris/rev4:default:flash</code></li> </ol> I would love to use the option 1 but for some reason docker cannot find the keyboard via USB and I had to install the tooling locally. I suggest you to start trying docker and if it didn't work, go for option 2. Compiling your own keymap</h3> I created my own keymap inside my fork</a> so it would be easy to keep the main code updated. So I have to use the following command to compile it: make keebio/iris/rev4:pothix</code></pre> If everything goes right, I just can just flash it. Connect the keyboard to the USB port and hit the RESET button. It may be via RESET button at the back of the keyboard of actually hitting the RESET key on the "LOWER" layer (check the default keymap for more info). After that, run the following command: sudo make keebio/iris/rev4:pothix:flash</code></pre> I'm not able to flash it without sudo, so keep it in mind when flashing. Remember to flash both sides because you may get incompatibilities and weird behaviors sometimes. Here is one I had: Optimizing</h3> Depending on what you're using on your keyboard, you may exceed the maximum size for the binary. If this is the case for you (as it was for me :P), you can start disabling features you're not using. This article</a> was very helpful for me to understand what can be done. If you want some examples, check my rules.mk</a> and config.h</a>. Conclusion</h2> It's not cheaper to build your own keyboard as one would expect, but it's definitely fun if you want to get your hands dirty with soldering to build something custom for yourself. I learned a lot in the process and I hope to be able to maybe build another keyboard in the future. It will probably not be the last keyboard I will build. I still want to build a dactyl-cc</a> at some point to take the place of my current Kinesis Advantage. It's a handwired keyboard, so I will have to move to the hard version of keyboard assembling. :) Happy keyboard building! ⌨ Review of Nonviolent Communication Unknown — Fri, 22 May 2020 00:00:00 +0000 Book: Nonviolent Communication</a> by Marshall B. Rosenberg. Rating: ⭐️⭐️⭐️⭐️⭐️. Great book! It's short and straight to the point. In summary, we should emphasize more with other people and understand what they are really trying to say. Sometimes we don't communicate well and it's up to someone to find out what is the problem and raise the right questions. This book feels even more important now that we have more people working remotely. Remote communication is even harder than face-to-face, so it's important to have a clear message. Here are my raw notes about the book: Non-violent communication is about contributing instead of fighting</li> There are other ways to make things happen than violence and punishment</li> Keep separate observations and evaluations. Example: instead of saying: "eat well or you will have bad health" say "if you don't eat well, I think you may have good health"</li> Instead of using: "Willian is a bad player" use "Willian did not make have any 3 point shoots in this match"</li> The word "feel" is usually misused. "I feel misunderstood". Being misunderstood is not a feeling but a judgment of how people will understand</li> Responsible == response-able. You're only responsible if you're able to do something, if you're in control. You're not responsible for other people's feelings — 💭 I would like to quote this many times IRL. It's worth mentioning that this is not an excuse to be an idiot.</li> We don't usually think about our needs. We think: "What is wrong with others that our needs are not being fulfilled?". If we're compassionate about others, we will understand what they are saying even if they are judging and attacking us by not understanding their own needs.</li> Don't use: "You misunderstood me" or "I was misunderstood here". Instead, use: "I think I was not clear, let me rephrase that" — 💭 This is something I've been using a lot and it's very useful</li> If you don't ask for exact topics you want to hear from people, you may receive feedback you're not interested in. Instead of asking for people's thoughts, ask for their thoughts about something in particular</li> If you don't know what the OP is expecting from something he/she is sharing, ask them: "What do you expect from the group by sharing this?"</li> We should empathize with people when we ask for something. Using phrases like: "Are you willing to do something" instead of " I would like you to do something". In the first case, we are requesting and the second may look like we're demanding</li> Let us become the change we seek in the world — Mahatma Gandhi</li> It's important to change your language to state that you do things because you want, not because you have to. The author's grandfather used to think differently about paying taxes. He immigrated to the USA from Russia and they felt contributing to a government they believe, so paying taxes not bad, but part of this belief</li> It's not the behavior of other people that causes us to be angry, but how we perceive it. Example: someone is late for a meeting. You may feel angry because you think you're wasting your time. You if were wishing for some time alone, you would feel good because the other person is late</li> We should always justify anger by our own feelings. Instead of "I'm angry because they/he/she did that" we should use "I'm angry because I'm ...". Other people's actions are just the trigger, not the reason</li> </ul> Review of The Antidote: Happiness for People Who Can't Stand Positive Thinking Unknown — Fri, 15 May 2020 00:00:00 +0000 Book: The Antidote: Happiness for People Who Can't Stand Positive Thinking</a> by Oliver Burkeman. Rating: ⭐️⭐️⭐️⭐️. It was a suggestion from a friend when I published the review of Don't Panic: Taking Control of Anxiety Attacks</a>, as he found the content to be complimentary. I liked the book overall. It's interesting how the author shows some scientific facts of the "positive thinking" which contradicts the current collective thinking. I don't have anything against positive thinking, but I'm sure positive thinking alone will not do much. There are many mentions of stoicism and I read better books than this one that was dedicated to stoicism itself. It was nice to remind me of some concepts to consider. Memento Mori was one that I found particularly interesting when I read A Guide to the Good Life: The Ancient Art of Stoic Joy</a>. My current way of thinking is that all could be much worse and "Is is the worse that can happen?". It helps to better evaluate the current situation. In the beginning, I had a 3-star review for this book, but the final chapters brought the 4th star. :) Here are my raw notes about the book: If positive thinking does not help, is it worth calling it positive after all?</li> Nothing is positive or negative per se, it's your perception that makes it good or bad.</li> Are things/people acting badly or it's us waiting for them to act in a different way?</li> The only things we can control are our judgment of things and how we can face them</li> Be upset about a situation (a long line in the supermarket) is irrational since you have no control over it. You have the freedom to go to a different supermarket or just be there and accept the situation #Stoicism</li> If you accept the universe to be uncontrollable, you will be much less anxious. There's always much worse situations and these are the ones we must fear of</li> Vipassana Vendetta. When your mind doesn't have big problems to think about, it will start creating new ones from simple situations</li> Always think about how bad it will be if you fail to do something. If it's tolerable, go for it</li> The ego is more focused in the future. It's much easier to think compulsively about the future than the present</li> You are not your thoughts. You can be a witness to them</li> We are not more insecure than we were in the past. There are countless manuscripts showing how people felt very insecure about many things since BC</li> We always try to find stability for everything. This is not possible because everything changes. We change. We are born, change, grow, and die. Nothing is the same forever.</li> We build castle walls to be safe, but that's exactly what brings the enemy. Because there are Castle walls, there's nothing to attack.</li> According to Ernest Becker, all religions, political identifies, and other projects are a way for us to feel immortal</li> Our immortality view is sometimes so important that we are willing to sacrifice our physical mortality for a sentiment of immortality (war)</li> The denial of death affects us a lot</li> Jean-Paul Sartre wanted to die quietly.... certain that the last burst of my heart will be inscribed on the last page of my work, and that death would only be taking a dead man</li> </ul> Review of Don't Panic: Taking Control of Anxiety Attacks Unknown — Tue, 07 Apr 2020 00:00:00 +0000 Book: Don't Panic: Taking Control of Anxiety Attacks</a> by R. Reid Wilson. Rating: ⭐️⭐️⭐️⭐️. A good book and exactly what I needed, thanks for the recommendation, Rafael Rosa! Some people said it seems like a Rust programming language book because of the word "panic" but it's actually related to panic/anxiety attacks. It's not the first time I suffer from anxiety but it's the first time I felt the panic attack symptoms, so I decided to read more about it. This book describes most (all?) of the symptoms that a panic attack causes and some ways to deal with it. There are many extreme cases being described here, which actually helps to find your own problems much less disturbing. The book tries to provide a set of tools to help you fight it yourself. The description of how anxiety works and how we make it worse is not new to me, but the tools the book tries to provide will probably be a good addition to my toolbox. :) Below are my notes. They are more personal than usual since I was reading with my own situation in mind. For patients with emphysema and bronchitis, the fear of being breathless seem to be at the root of most of their problems</li> There's a feeling that the body is in a "dream-like state", called depersonalization</li> The first panic attack seems to come out of nowhere, but it usually appears after a long period of stress (change of jobs, promotion, the birth of a child, etc)</li> For some people, managing to reduce the stress fix the panic attack problems, for others, the panic appears to show them some psychological trait and they start to be doubtful of their skills to handle the situation</li> In the gastro-interspinal system, anxiety causes the symptoms of difficulty in swallowing, butterflies in the stomach, the gurgling sounds in the stomach and intestines, diarrhea, and cramp-like pains in the upper stomach.</li> Some circumstances make people face fear instead of letting it become panic. Facing fear when it appears is a more effective way to not let it grow</li> Do not reject compliments with self-deprecating comments. Just say thank you.</li> If you ignore your feelings, they will grow and grow. Once they are so big you can't ignore them, they scare you instead</li> We have breath patterns in many situations and feelings. People with lung diseases may not react well to some of those patterns.</li> As soon as they start thinking negatively about the future, they fall into the panic trap. She (in this case) feels a smothering feeling, which brings all the other feelings</li> Don't keep monitoring your body all the time, let your unconscious mind to take care of it. Your unconscious mind does it very well, all the time, just share your burden with it without worrying too much</li> If you felt panic once, your brain may have created a cue to activate the emergency system next time it felt any symptoms. You have to learn to deactivate the emergency mode when there's no real danger to worry about.</li> Don't avoid situations where panic may happen, learn to cope with it and face the fear. Being against panic only makes your anxiety worse. Learn to face your discomfort.</li> Most problems with anxiety come from the fear of uncertainty. Living demands risk. 0 risk is too much to require from life. Questions like "Can I know for certain that I will not ...?" are a real problem and you need to confront them and learn to accept risk.</li> Being open about panic attacks makes things easier as you are preparing the environment for not being ashamed if something happens. Such behavior helps to reduce the anxiety</li> Removing the demand for success actually increases the chances of os success.</li> Challenge panic or anxiety (as if they are separate entities) to generate even more fear or catastrophic scenarios. You can handle this and see that nothing catastrophic will happen. It's just a test, you don't need to worry.</li> Observe things without taking action from your observations. Instead of judging a symptom when you start feeling it, take some time to consider the whole situation and remember this is not an emergency, so your body will have a better reaction. When you assess a symptom as the worst-case scenario, your body pushes the panic button to protect yourself as if it was a life-threatening situation</li> Create a supportive observer to support yourself and directly face your negative observer (who says everything is a catastrophic experience)</li> Fight against what you are feeling only makes things worse. Try to shift your thoughts away from what you're feeling</li> The trouble with our conscious mind is that it tries too hard</li> She hardest task for concentration is to quiet your conscious mind</li> </ul> Review of Essentialism: The Disciplined Pursuit of Less Unknown — Mon, 09 Mar 2020 00:00:00 +0000 Book: Essentialism: The Disciplined Pursuit of Less</a> by Greg McKeown. Rating: ⭐️⭐️⭐️⭐️. Nothing outstanding, but a good book overall. I like listening to books like this one from time to time as it helps me to again think about what is essential. This topic is something we tend to forget and having a reminder is nice. Sometimes we have so much noise around that it's hard to find what is really essential to us. Don't let things/people guide your decisions, think deliberately about what you think it's important for you and do it. Here are my notes for this book: Just because you're invited, it doesn't mean there's a reason good enough to attend Do important things and eliminate everything else Almost everything is noise, you have to find what matters Essentialism is the search for "less but better" Priority was a singular word in English and means the prior thing to do We simply can't do everything, there's a limit to our time and attention We either make our choices deliberately or let other people do it for us If you're not sure about the value of something you have, ask yourself: If I didn't have this already, how much would I pay for it You may not have control over what happens, but you have control over your choices An essentialist thinks almost everything is not essential A non-essentialist says: "I can do it all". An essentialist says: "what trade-off I have to make?" Essentialists explore more options so they can find the vital few they want to focus on It's important to make space on your life to think and do what really matters to you The word company is a reference to a military unit If you think you are tough and can do anything experiment saying no to an opportunity and taking a nap Sleep is essential to your health and performance Ask yourself the question: If I didn't have this opportunity, what I would have to do to have it? It will help you to decide if you should say no Mastering the discomfort of saying no is an important skill for an essentialist. Talk about this in a dinner table is easy, but seeing people living this is rare People are effective because they say no Separate the decision from the relationship. Saying no to something is not denying the relationship Editing life: cut down options Create your own boundaries so it's easier to say no Find your deal-breakers. What are the activities you will NOT do if it's not aligned with your goals Create a buffer of time for your tasks. If you finish the task as planned, you have a bonus time for yourself. If you have any problem, it will not be stressful Before starting a project, list all obstacles you may face and find the one that may be blocking others so you can focus on it first (the slowest hiker) Start with minimal viable improvement, even if it takes less than a minute, it's a good start to get momentum Essentialists create a routine to make essentials the default action A good approach is to assign a theme for a day in your routine. Mondays for meetings, Tuesday for development, Wednesday for support, etc. "In work, do what you enjoy. In life, be completely present" -- Lao Tsu Think about your life and find what is essential. Eliminate everything else. Clarity is success. As a manager, it's essential to make things clear for your team to perform well Peter Thiel PayPal executive asked people to have just one single priority for their role and focus on that. Review of The Courage to Be Disliked: How to Free Yourself, Change your Life and Achieve Real Happiness Unknown — Thu, 13 Feb 2020 00:00:00 +0000 Book: The Courage to Be Disliked: How to Free Yourself, Change your Life and Achieve Real Happiness</a> by Ichiro Kishimi. Rating: ⭐️⭐️⭐️⭐️⭐️. I love these kinds of dialogues where both sides know how to win something. Currently, there are not many good dialogues on our society, especially with the advent of social media (🙄), but I would not go into detail here. The whole idea of Adlerian psychology is very interesting. In some parts, it reminds me of what stoicism says, especially the parts of the "here and now". It's been a while since I was finding excuses to go out for a walk just to listen to the audiobook. :) Here are my raw notes about the book: It's impossible to share your world with someone else. We have our view of the world</li> If you change, the world will be simpler</li> We're looking into the world through dark glasses. We can complain about the glasses or just remove them. Do we have the courage to remove them while everyone else is using them?</li> Trauma doesn't exist. What you feel is something you projected to meet a goal. Example: I don't want to leave home, so your body will react to this goal. The feeling is real though.</li> A mom was shouting at her daughter and then the phone rings. She picks up the phone and talks in a soft voice. When the call ends, she gets back to shouting. Shouting was a tool to overpower her daughter, not just an instinct</li> The past doesn't exist. You, living here and now, will determine your future</li> Our fear of being rejected creates some reactions (blushing, not wanting to get out of our house, etc.) to justify not exposing ourselves to something that could end badly (according to the philosopher)</li> It's impossible to not get hurt or hurt other people when doing interpersonal relationship</li> All the problems we have are interpersonal relationship problems</li> The feeling of inferiority is a subjective view. We can see our inferiority as good or bad, depending on how we face them. The value of a diamond is subjective according to interpersonal relationships</li> One can use their inferiority feelings to dominate people by telling people how much they suffered, thus controlling their discourse. The most powerful being is the baby in terms of control.</li> Admitting mistakes is not a sign of defeat, it's a way to grow. If you have the win-lose mindset, you will want to win all the time and will take the wrong path more often — 💭 So true. The worst part is how hard it is to tell people they are in a win-lose mindset.</li> Instead of trying to change others, you take the step over and change yourself</li> We have to live our lives for ourselves, not to praise others</li> The counselor doesn't change someone's life.

Unknown — Sun, 26 Jan 2020 00:00:00 +0000 Brace yourselves, like any other stats post, this one will be HUGE My year in review for 2018 was never posted because I could never finish it. I don't want to let the same thing happen this year, so here I am. The end of 2018 and the beginning of 2019 was quite hard for me and me just didn't have the energy to sit down in front of the computer during the weekends to write my monthly reviews. </a> Some people still ask me to get back to write such reviews, but I couldn't make this a priority for myself anymore. I don't want the same to happen to my Year in review. I do it for many years already and I plan to keep doing it for a long time. So let's start! Average day</h2> Let's start with what an average day is to me according to Exist.io</a>: </a> This is almost a TL;DR of this post, but there's a lot of details missing here and we will cover them topic by topic. 😉 Books</h2> </a> Although I did not meet my goal of 30 books read this year, I still consider the 25 books read an achievement. At some point, I realized I was choosing my books to meet the goal. When picking a new book from my wishlist, I was choosing the smallest ones first, not necessarily the ones I wanted to read the most. It's not that bad, as I was still choosing books from my library and wish list, but I don't want to have such influence in the titles I pick. 25 books is a great mark IMO. You can see my 2019 Goodreads challenge here</a>. :) I'm still using Google keep</a> to take notes of all the books I read and I'm posting Goodreads reviews for them based on these notes. You can see the reviews for 2019 by clicking each book on my Goodreads page</a>. Here are the books from this year's list that I really recommend reading, with links to my review: Why We Sleep</a></li> Homo Deus</a></li> The Power of Habit</a> (second time I read this one)</li> Atomic Habits</a></li> Deep Work: Rules for Focused Success in a Distracted World</a></li> </ul> There are also some from 2018 since I did not post my Year in review last year: When</a></li> Sapiens</a></li> A Guide to the Good Life</a></li> Principles</a></li> </ul> You can always look for my whole list of books read in 2019</a> and 2018</a> on Goodreads. Here are some stats provided by Goodreads comparing all the books I have registered: </a> I started listening to audiobooks</a> in 2016 and we can clearly see how excited I was. 😅 I can see now that I'm reducing the number of books I'm reading every year, but I don't think I should be concerned about that. The number should not surpass the quality of books and how much I'm applying what I learn. Let's compare the books I read this year with last year: </a> I used the number of pages because it clearly shows that I even read more than 2018, but not more individual books. I was not expecting that but it shows that I was trying to be less focused on the number of books. In 2017, I mentioned that I was disappointed with the number of 5 stars I gave. It was probably related to the fact that I was buying cheaper books and focusing on smaller ones as well. In 2018, I tried to fix that and it works. I gave 7 five stars reviews in 2018 and five in 2019. It seems these metrics were useful after all. :) In 2018, I read 2 books from my "audible-deal" shelf and in 2019 I read none. From all the books I have on my "audible-deal", none of them were 5 stars. This is probably a bad sign. On the other hand, I found some great books there and I don't regret reading them (Spaceman</a>, Rendezvous with Rama</a>, What Doesn't Kill Us</a>, etc.). I was not feeling so good about the number of books I read this year, but after writing this section I'm feeling much better. I'm happy with my results here. :) Articles</h2> I couldn't finish my year in review for 2018, but the part about articles was done, fortunately. There's no way to get the read date from Pocket, so if I want to collect it, I have to do it from time to time. Thanks, past self! It was not in vain after all. If you're reading this, I was successful in publishing this time, so this is good news. 🤞 Different from the review I did for 2017</a>, I will now have data for the full year. I will also mention the data I had for 2018, since they were collected but never published. In 2018, I had 1733 articles unread (22% increase compared to 2017) and 1456 articles read (31% increase compared to 2017). In 2019, I have 1908 articles unread (9% increase comparing to 2018) and 1731 articles read (16% increase compared to 2018). It means that I read 275 articles this year. It's a bit worse than 2018 when I read 381, but it's still a good number IMO. It's an average of 23 articles each month. Again, it's worth mentioning that I'm aware that I will probably never read all those 1908 articles left in my Pocket account and I'm OK with that. I was expecting to have more data from Exist.io</a> regarding articles this year, but unfortunately, it was a bit disappointing to not have much. They provided a year in review, which I'm going to mention later, but the only thing about articles is that it says I read 263, which is quite close to the number I had above. :) Coding</h2> All my coding metrics are provided by Wakatime</a>. When we have a light blue bar inside a dark blue one, it means the light one is the global average and the dark one is the top coder. We should usually focus on the light blue part of the bar. First, let's take a look at the total time coding: </a> My daily average this year is even lower than the 1h31 per day I got in 2017, which looks really low for me. I'm still above the average, but 47 mins on average is a bit weird. 😐 I remember the official Wakatime profile added a comment to my 2017 post</a> to mention that it may be related to the way Wakatime records the numbers. I remember tweaking things a bit but I'm not sure if I should increase the numbers to have unrealistic reports. Maybe I should try to tweak the data collection once again. </a> I dedicated only 22 hours to this blog, compared to 80+ hours in 2017. I would like to improve this, but I'm not sure if it will be a priority, unfortunately. Todoist</a> is my top project for this year, which is expected since it's my main job. I expected to have more time tracked there, but I'm not only coding for the main Todoist repository, so it makes sense. I hope to also have Twist</a> as a relevant project on my list of projects next year, or at least have integrations related to it. I still keep the same freelance job I have for more than 4 years now. It became almost a personal project for me. The good part of working for them is that the work is just coding and mostly fixing bugs. I just need to sit down and write some code. This year was totally atypical since I took some time to migrate the framework and infrastructure of this project. It was a big challenge, especially for someone working using their spare time for that. I expect the number of hours working on this project to totally shrink in 2020. Let's see. </a> I'm just using Linux, so it's expected to have it here. I'm using it much more than the average as we can see. The "top coder" is an outlier for sure. 😜 In 2017, I wrote: Looks like I fully switched to Emacs. It seems things have changed again. I'm back to Vim now. 🙂 </a> Markdown is still in this list for the same reasons I had in 2017: I still write posts on my blog using Markdown</li> I'm responsible for Todoist</a> and Twist</a> documentation</li> I usually write a long post in Emacs/Vim and then paste them to Twist</li> </ul> There's no surprise that Python is the language I used the most this year, since we use Python for almost everything at Doist</a>. I use Ruby at my freelance job, so there's no surprise to still have it there. In 2017, I mentioned that I don't think I will have enough ground to play with Elixir this year but maybe Rust will have his time in my schedule in 2018. It was true about Elixir, unfortunately, but I had an improvement for Rust 🦀. I even had my first change merged into the compiler</a>! The change itself was quite simple, but it was great to understand how to contribute and hopefully, new contributions will come this year! Speaking</h2> After 2017, I had a hangover of speaking. 😅 For those of you who remember, I spoke 24 times in 2017. I decided to create some sort of a challenge for myself to speak more and was quite successful at it. After such an achievement, I decided to change my priorities. 😃 To make things easier to track, I now have the talks page</a>, which I'm going to use it as a reference here. In 2018, I spoke 7 times with 6 different presentations. 6 different presentations delivered in pt-BR and one of them delivered in English.</li> In 2019, I spoke 2 times and both were the same presentation. I spoke at the local Ruby meetup and brought that same (slightly changed) presentation to Rubyconf Brasil.</li> </ul> We can clearly see that I'm slowing down my pace of presentations. I came from 24 presentations in 2017, to 7 in 2018, to 2 in 2019. That's exactly what I wanted to do. I have to say that I was already feeling bad to not be speaking for some time and I was eager to speak in 2019. 😅 I don't think things are changing much for 2020 though. It's also worth mentioning that I was also on stage last year, but not delivering a talk. I was one of the core organizers of Rust LATAM</a>, the first big conference about Rust in Latin America. It was a great experience and you can read more about it here</a>. Completed tasks</h2> Every year Todoist releases an astonishing Year in review. Here is mine from 2017</a>, 2018</a>, and now 2019</a>, which is the one we're going to explore. Let's check my Todoist tasks! 🙂 </a> </a> 6198 tasks are less than what I expected since I completed 6323 tasks in 2018. It's not a huge problem because it always depends on how you organize your task manager. In my case, I also have my routine on my task manager so it can help me to actually do the things I plan for myself. The plan for 2020 is to remove my routine from Todoist and move it to my calendar, so I can only have the important tasks there. By removing these tasks from Todoist, I will probably have a report with fewer tasks next year and that's OK. 🙂 It looks like Friday is the day I complete more tasks: </a> I think it happens because I usually post my snippets every Friday, so I complete the list of tasks I have to post there every Friday. My most productive time is 10:00 (not 16:00 as I had in 2017): </a> I found it very interesting that the productivity chart correlates with my When tracker</a> (wrote about it on my current productivity workflow 2019</a>): </a> Let's see how those tasks are distributed throughout the year. You can clearly see my vacations on the light gray columns: </a> I'm still one of the 1% heavy users of Todoist! 😃 </a> The data and design of our year in review is awesome. I did not participate in the project this year (as I did in 2017), but proud of what we can deliver. 🎉 Podcasts</h2> </a> </a> Unfortunately, I don't have data about 2018 anymore, so I will just mention 2019 here. If I was listening to the episodes in normal time (spoiler: I wasn't) it would be equivalent to 18 days and 4 hours of non-stop listening. As I usually listen to Podcast in 2x or more (depending on many factors), I would say I spent around 9 days listening to Podcasts, which is effectively around 216 hours of my time. I usually listen to podcasts when I'm commuting, walking the dog, washing the dishes, doing exercises, etc. I'm usually focusing on audiobooks</a>, but I listen to podcasts between one book and another. The list of podcasts shown here is actually my global list, not the yearly one, unfortunately. I'm not even listening to new episodes of some of these anymore, but they are still there. Hours working, focusing and distractions</h2> Let's start checking all my data tracked using Toggl</a>: </a> The gray bars are related to the data for 2018. I believe the changes are related to my scheduled vacations. :) Let's check my time working, considering my full-time job only: </a> April was conference + retreat + vacations for me, so it's an outlier. Considering 40 days of vacations during the year (we don't have national holidays, they are included in the 40 days) and dividing the average of 151 hours a month by 18 (21 working days - 3 days of vacations per month) I have an average of 8 hours and a half of work every day. At Doist</a>, we recommend to not work more than 8 hours a day, so I'm working a bit more but it's under control. I spent 81 hours of my year in meetings. Most of them were weekly sync meetings with my remote team and also a monthly 1-on-1 with the head of my team. I consider all of those meetings productive. There was not a single meeting last year where I found myself wasting my time, so these 81 hours are actually fine. The most interesting part for me is the Shallow x Deep work ratio. I have almost 3 times less time Deep working than Shallow working, which is not that good. This is totally something I have to improve in 2020. To give a bit more context, I consider Deep work any work I can do without distraction. Shallow work is the work I do while I have other tabs opened on my browser or while I'm doing something else on the side. I think I'm not tracking that as I should. Sometimes I'm focused on reading Twist and answering questions, but as it's not coding, I consider it as shallow work. I will certainly improve it for 2020. 🤞 As I mentioned in my previous review, I keep one freelance job, which is almost a personal project for me. I like to improve the app and make it better. I don't have freelance gigs, but this one I'm happy to keep. Here is the time I tracked about it this year (based on Toggl, not totally accurate): </a> June is an outlier as I did the migration of the application to a different infrastructure in one weekend. It was an exception as I don't work during weekends most of the time. As it was my idea to do this migration, it was personal to me. This migration project was the topic of my two presentations this year, as I knew it would be an interesting topic to talk about. Other than that, I usually don't work more than 20 hours a month for them. I reserve some time every weekday to work on different things. This project is usually the first in the list, but sometimes I just don't want to work on it and decide to use my time for other things (tech-related or not). What I wrote on my 2017 Year in review still holds: I really like my full-time job (more than ever!) but I like to do different projects without constraints, it can be this freelance job or other activities that also brings me joy.</code></pre> I have a metric for the time I spent doing/planning my talks this year: </a> June was a busy month, just because I decided it would be. :) I want to keep track of presentations, writing on my blog, etc. because I can easily metric how much I'm donating to the community. Sometimes, instead of working for my freelance, I decided to write and publish something that may be useful to someone else. Sometimes I decide to create slides for my next presentation at a local meetup. If I take the ~10 hours, I can easily measure how much I'm donating to the community by applying my freelancing hour rate. It may be useless for other people, but it's highly valuable for me. I don't want any money in exchange, but it's important for people to know that others are donating their time because they like to do it and because they believe it may be useful for someone else. I've been participating/organizing communities for more than 10 years now and I know how easy it is for people to take local meetups for granted as it is free and someone else is taken care of it. Moving along with the metrics, let's check what data rescuetime</a> can provide regarding my productivity. :) Let's look at the productive and distracting hours for the entire year: </a> The metrics of 2018 were not posted last here but here are them for comparison: </a> This is part of the year in review</a> provided by rescuetime. They also provide a chart with the categories I used the most: </a> The dashboard shows similar information but with some other things: </a> </a> I had a lot more productive hours than I had in 2017 or 2018 and this is a good thing. 🙂 Music</h2> Again, last.fm</a> did a great year in review for me, so let's check some stats here. </a> </a> </a> </a> I'm using Google Music</a> for two years now, so I was already expecting to not have 500%+ on my Discovery as I had in 2017. My Discovery this time is mostly related to Pops Staples, which is awesome BTW. As usual, I'm listening to a lot of Heavy and Thrash metal, along with a lot of Soundtracks, which is mostly Howard Shore (no news here). In 2017, I listened to more music between 20:00 nad 21:00 and how it changed between 10:00 and 11:00. I believe it's because I changed, even more, my routine to be even more a morning person. I usually use music to focus or to create the mood for the day, so it would make sense. I have no idea why Thursday is the big outlier this year. Maybe because I'm afraid about the end of the week and I'm using music to concentrate to deliver everything I postponed on Monday, Tuesday, and Wednesday? LOL Exist.io</a> also provided data about the songs I listened to (via Last.fm): </a> This is the piece of information I was missing from Last.fm, so it's nice to see it here 😃. TV Shows</h2> I had a topic for TV shows in 2017 and I'm just realizing how this is not a priority for me anymore. I'm not tracking the TV shows I watch and I'm not even watching that much anymore. There are some TV shows that I watched and enjoyed though: Game of Thrones (it's not about the end, but the journey) and Vikings. Westworld Season 2 was OK. There's also Altered Carbon I watched in 2018 that I enjoyed, the concept is great. To be honest, I don't even remember the ones I watched. I tried to use Trakt.tv</a> but they don't provide your data if you're not paying, so... whatever. I checked TV time</a> and it seems they are adding movies to the app, so maybe I will start using it again since the app is great. Physical data</h2> In 2017 I had a hard time to come up with the metrics for my Physical activities and it seems things did not improve in the past two years. Someone may say I should buy the expensive band X or the super expensive hardware Y, but please don't. I prefer a simple and inexpensive device that tracks and sends the data to other places. Getting back to what I have. Now I can't get that many bars on screen no Miband and they only provide a monthly summary, not an early one. Google fit is not very helpful as well: </a> </a> </a> My savior this time will be Exist.io</a>, because they have monthly averages: </a> It's just an average, not the full number of steps, but it's good enough. I don't need the total number of steps by year, as my goal is just to understand if I'm walking enough, and I don't need a precise number for that. Google location timeline gave me some yearly numbers about walking and public transportation: </a> </a> It's nice to see I walked more than 800km this year. April was the month I had more steps and it was probably because of my vacations in Portugal 🇵🇹. Weight</h3> I tracked my weight this year as well, here is the data I have: </a> </a> Some data is missing from January to May, but after that, I took the Gym and diet seriously, so we can clearly see how things start to improve. When I got back from vacation (October), I was ready for some improvement again and I lose more weight. The weight doesn't mean much as there are many other important things to track. In my case, I know it was not just weight, I have better muscles than last year and feel much better as well. I don't have that many metrics from the Gym. To be honest, I don't like Gyms that much, so I try to do only do the really necessary things. I do measurements from time to time because it's provided by the Gym. I do everything on paper there, so I don't spend any time with that. I take pictures of the data and keep it with me. This time I decided to just quickly put that on a spreadsheet and generate some charts. Here is what I have since 2018: </a> As you can see, there's not much data and data is missing sometimes for some reason. All measurements are done in centimeters (of course). For the three initial charts, the less the better. The opposite is true for the charts below it. There's not much to correlate between the Gym measurements and the weight though. Sleep</h3> Again, the Miband app is not very useful: </a> </a> I sync the same data with Google fit and connect it to Exist.io</a>. Those two services provide some good visualizations of my data: </a> </a> I finished reading Why We Sleep</a> in July and I was curious to see how changing my routine influenced my sleep. I was expecting to have a more immediate impact on August or September, but I can see I only had a real impact after September. :) I'm also using the Sleep as Android</a> app to get some sleep data. I connect it to my Miband and let it track. Here is the data I was able to extract from the app: </a> </a> I'm a morning lark. I usually work better in the morning and go to sleep earlier. The average duration of my sleep is a bit low in this app for some reason, but it's usually between 7h and 7h30m. The Efficiency is the time I'm in bed but actually sleeping not browsing the internet or having problems to sleep. 93% is a good value. </a> </a> My deep sleep is decreasing in the past months for some reason, I have to improve this situation. I believe the decrease of deep work is happening because of my habit of looking at my cellphone before sleeping. I will try to cut the cellphone at night again. My irregularity of sleep is also not good, I should have close to no irregularity of sleep. I hope to improve that until the middle of the year, after that I can't promise anything. 😉 </a> </a> It's interesting to see that I usually wake up later and sometimes sleep more when it's "free days" (holidays and weekend), but most of the time I keep the same duration. The time I go to sleep is also clearly related to the duration of the second chart. I believe this is pretty common since I have time to wake up but not a time to go to sleep. I'm aware of the problem already and I hope to improve it. I'm happy with the sleep data I have and I have to say I'm curious about the data I will have about that next year. Words written and errors</h2> This year I didn't have the data to consolidate and I don't want to check every weekly email to consolidate it. Grammarly will have to do better if they want their customers to get better data about their writings. Sorry Grammarly, weekly emails are not enough. This is the data I have from the last email I received before my vacations in December: </a> </a> We can see that I wrote almost 1.5MM words since I started. I checked the first time Grammarly sent this number and it was 963,838 words written on Feb 11th. Let's do a simple math: 1478380 - 963838 = 514542 -- words written between Feb and Dec 514542 / 10 = 51424 -- words by month (Feb -> Dec)</code></pre> It seems I write around 50k words every month. It would be around 600k works a year. 🙂 I would love to have a chart like the one I had in 2017</a> so I could see what errors I had and so on but it's not viable, unfortunately. 😕 Locations</h2> In 2018, I went to Chile and the USA. In 2019, I went to Uruguay, the USA, and Portugal. Here is the summary of the year and all-time data by Google: </a> </a> I have to say that I'm very proud of myself when I see all-time data. I believe that getting to know other places and cultures is something that expands your mind in many ways. 🙂 Here are some of the cities and places I visited this year: </a> </a> I'm quite satisfied with my trips in 2019. Expenses</h2> I have some sad news about my expenses data this year. The app I was using before is now even worse, so I decided to not use it anymore and remove all my data from there. The good news is that I decided to invest more time on investing this year, so I had to organize my finances somehow. Because of the need for an organization, I had to get all my investing data into one spreadsheet. I decided to use dlombello's</a> spreadsheet for that (pt-BR only). I have to say that I'm amazed by how feature-complete is this spreadsheet. It's still worrisome that you have to give full access to your Google account for it to work (because of external scripts), so I created a Google account just for that. Until now, it totally worth the effort. Here are some charts I can get from the spreadsheet: </a> </a> The first chart shows the types of investments I have. The Orange and green are related to the stock market and the rest is bonds and others. The second chart is the indexes these investments are related to. I don't think these charts are very good, but I started to use this spreadsheet last month and I don't have that many ways to retrieve good information from it yet. I hope to have better data next year, let's see how it goes. 😉 Regarding my savings, it increased by 23.87% this year (compared to 26.72% in 2018 and 16.83% for a bit more than half of 2017), an average increase of 2.57% per month. In 2017, I said I had 75.10% of my savings goal. Well, I met this goal in 2018. 😅 The plan was done long ago and it doesn't make sense anymore given the current economic conditions. I decided to keep it anyway as it would be good to keep the history until I meet the goal. When I finally got to the value I wanted, I started a new plan. Considering this new plan and the whole year of 2019, I have 89.40% of my goal. I know it's weird to just introduce this value without further background, but just wanted to keep it here for my future self. Given the current circumstances and my life choices, this goal will have to change this year. I'm OK with these changes, it's important to have plans but it's also important to change them if the circumstances require such change IMO. I'm looking forward to seeing what this new year will do to my expenses and general portfolio 😅. Time to write this blog post</h2> Phew... finally finished this one. 😅 This time I could track the whole process and it took 17h21min to write this blog post. </a> I can say the same thing I said in 2017: It totally worth my time to write this. We have so many good insights when reviewing the data we collected. 😌 Conclusion</h2> I have nothing to complain about 2018 and 2019. The only thing I should have done earlier in the year in review for 2018 because it totally changes my mood about what I did. It's great to do reviews because you can clearly see (at least it's the case for me) that you did what you wanted to do in the general context. It's clear to me that doing my year in review in 2017 helped to improve things I could only see when looking in "bird's eye view". Some things are not so noticeable when you're seeing them in context, but they become clear when you put them in a yearly context. I'm sure 2020 will be a year full of huge challenges for me, but I'm also curious to see the data I'm going to collect this year! 😉 Diadema Unknown — Wed, 01 Jan 2020 00:00:00 +0000 Morei em Diadema por quase 30 anos. Desde os 7 anos de idade até os 34. Por muito tempo morei no suburbio, próximo a divisa com São Bernardo do Campo e São Paulo. Nessa época eu não tinha muito a recomendar sobre a cidade, era basicamente sobreviver e crescer. Quando casei, me mudei para o centro de Diadema, próximo ao Shopping Praça da Moça. Nessa época eu comecei a conhecer melhor a cidade e aproveitar algumas coisas. Segue as dicas de coisas que eu gosto na cidade (em 2022): Shopping Praça da Moça: É um shopping simples, mas legal. Eu gosto da forma que o shopping é administrado e das coisas que tem lá. O fato de eu ter morado muito tempo bem próximo me deixou conhecer mais a forma deles de trabalhar. A única parte ruim é não ter quase nenhum filme legendado no cinema deles, mas isso não é só uma coisa de Diadema.</li> Playarte Praça da Moça: O cinema em si é OK, o que eu queria deixar de dica aqui é para ficar de olho na lista de filmes. Sempre que há lançamento eles fazem uma ou duas seções do filme legendado. Como ninguém gosta, é uma ótima oportunidade de curtir um filme com pouca gente e audio original.</li> Parque do paço: O parque é relativamente pequeno, mas bem gostoso de passar uma manhã ou tarde. Eu costumava jogar basquete quase todo domingo de manhã por lá e era bem divertido. Mesmo que só para caminhar, vale a pena.</li> Toninho da picanha: Apesar dos preços mais altos, vem bastante comida e eu gosto bastante das carnes. Recomendo!</li> Mania de churrasco, Shopping Praça da Moça: Sempre fui bem tratado por lá e a comida é bem boa. É um lugar que dá para comer tranquilo e tem tanto lanche como pratos mais convencionais.</li> </ul> Indaiatuba Unknown — Wed, 01 Jan 2020 00:00:00 +0000 Indaiatuba é a minha cidade de escolha para morar a partir de 2022. Por muitos anos eu queria me mudar para o interior de São Paulo, mas nunca foi uma realidade. Agora com filhos e precisando de um lugar maior/melhor, decidi por Indaiatuba e espero morar muitos anos aqui. Porque Indaiatuba?</h2> Essa seção vai ser um pouco longa porque quero contar a história completa. Muita gente me pergunta porque eu escolhi Indaiatuba para morar, especialmente porque eu não tenho família aqui e conheço pouquíssimas pessoas que moram por esses lados. Com os filhos, meu apartamento em Diadema não era o suficiente mais. O layout era desconfortável e a gente já estava achando pequeno para uma família de 5 (2 adultos, 2 crianças e um cachorro). Desde o começo da minha carreira, meu plano era ter minha própria empresa, trabalhar remotamente, e morar no interior de algum lugar. Eu tenho minha empresa e trabalho remotamente, portanto estava faltando me mudar para o interior. Aproveitamos que tudo estava se conectando e começamos a busca por outro lugar para morar. A gente podia escolher qualquer lugar no mundo, literalmente. Era só querer e planejar. Não seria um problema para o meu trabalho e minha esposa ia se virar bem com certeza. Depois de conversar bastante, decidimos que queriamos ficar perto o suficiente da família para fazer uma visita de fim de semana. Essa decisão limitou nossa escolha a um raio de ~200km de Diadema/SP, portanto eliminamos todo o resto do mundo da decisão. A ideia é que conseguissemos chegar em Diadema em menos de 2 horas. Tinha também alguns critérios adicionais para a avaliação: Cidade segura (o suficiente para o nosso gosto)</li> Fácil acesso a rodovia</li> Boa rodovia para Diadema, dado que vamos pelo menos uma vez por mês</li> Ensino bom e acesso a escolas que consideramos boas</li> Um condomínio de casas que a gente goste</li> Bons espaços públicos</li> Facil acesso a algum aeroporto para viajar e receber meus pais, que moram no Ceará</li> </ul> Algumas cidades que consideramos: Sorocaba: tenho amigos lá que falam muito bem da cidade. Estava numa boa posição no nosso ranking.</li> Salto: a cidade parece legal e com custo de vida bom. Estava bem posicionada no nosso ranking também.</li> Campinas: Cidade muito grande, a gente queria algo menor.</li> Boituva: Meus padrinhos moram lá e tenho outros amigos que curtem a cidade</li> Itupeva: Ficamos numa chácara num condomínio simples e legal. Gostamos da experiência como um todo.</li> Jundiaí: Acho que é maior do que a gente queria, no fim não demos tanta atenção.</li> Vinhedo e Valinhos: Essas duas entraram na nossa lista, mas acabamos não vendo tantas vantagens.</li> </ul> Indaiatuba atendeu todos os nossos critérios. A única desvantagem é que as coisas são caras por aqui, mas decidimos investir mesmo assim. Coisas que eu gosto de destacar: Tem muitos condomínios de casas por aqui, para muitos gostos e orçamentos. Escolhemos um que nos dá acesso fácil ao parque ecológico da cidade. Adoramos o condomínio na primeira visita. Temos um amigo que mora aqui, o que facilitou também.</li> A rodovia dos bandeirantes (melhor do país) é a rodovia que liga Indaiatuba a São Paulo</li> O ensino é bom quando se compara cidades com o mesmo tamanho</a>.</li> O acesso ao aeroporto de Viracopos é bem fácil. Em 20 minutos de carro eu estou lá buscando meus pais que estão vindo de FOR.</li> A cidade tem um índice de desenvolvimento ótimo para a categoria dela</a></li> Os espaços publicos são ótimos. O parque ecológico é incrível e tem outros parques legais também. Para quem vem de Diadema, ver a quantidade de opções de lazer parece um sonho.</li> </ul> É claro que nenhuma cidade é perfeita. Alguns items que eu destacaria: É uma cidade bem cara. Não só na compra de imóveis, mas valores de serviços e outras coisas. A cidade é bem elitizada no geral. Isso traz coisas boas e ruins.</li> Mega calor. No verão as coisas são tensas por aqui.</li> A cidade está crescendo bastante, com isso você sente uma certa gentrificação. Toda a descrição que eu dei até agora é parte disso. Não sei muito bem o que fazer sobre essa situação.</li> </ul> Dado o tipo/tamanho de cidade que estavamos procurando, Indaiatuba se mostrou a melhor opção. Estou bem feliz com a nossa escolha. Agora de volta ao procedimento normal das cidades que eu descrevo</a> 😅. Moradia</h2> O mais próximo do parque ecológico possível. É uma área muito boa. Tem desde casas, condomínios e prédios por ali, aí vai do seu gosto e orçamento (porque a região é cara). Entretenimento</h2> Magic the Gathering: X1 Arena cards</a>. Tem um grupo no WhatsApp para o pessoal que joga na loja também.</li> </ul> Comida</h2> Bologna Rotisserie</a>: Meu restaurante delivery preferido. Bem fácil de pedir pelo WhatsApp e entregam bem rapido. Os marmitex tem preço tão bom quanto do Caseiro e eu prefiro a comida deles no geral.</li> Restaurante Caseiro</a>: Comida simples e preço bom. Os pratos são bem servidos.</li> Restaurante Caipirão</a>: O forte deles é o parmegiana. Já pedimos delivery e fomos até o local também. O parmegiana é bem bom e bem grande, serve varias pessoas. O restaurante físico deles tem um ambiente bem legal, pena que quando visitamos eles tinham meio que desfeito o espaço kids.</li> Hamburgueria O Burguês</a>: Tive problemas em uma entrega, mas resolveram tudo e me deram outro lanche. Curti o lanche no geral.</li> The Dragon's Kneipe</a>: Hamburgueria fantástica. Não só o lanche é ótimo, mas a experiência toda foi muito boa. Eles criaram uma temática medieval que para mim tem um ótimo apelo. Provavelmente a melhor experiência que eu já tive com delivery de hamburguer.</li> </ul> Com espaço kids</h3> Para quem tem crianças, isso é bem importante. Eu tenho descoberto as maravilhas de restaurantes com espaço kids e quero deixar as minhas recomendações aqui. Mundo animal</a>: O restaurante fica no centro, bem acessível, mas sem estacionamento. Fomos num sábado e estava relativamente vazio. O playground é fantástico com monitor e a comida é mais ou menos. As opções nunca são saudáveis por lá. As crianças sempre se divertem muito. O valor é OK dado a estrutura, mas se for só pela comida dá para comer melhor em outro lugar.</li> Restaurante Santo Parque</a>: Ao lado do parque ecológico. Ótimo estacionamento, bom playground com monitor, comida boa e ambiente legal.</li> The Cleaver burger</a>: Um esquema mais burger mas com uma brinquedoteca pequena. Funciona bem para levar as crianças e comer algo diferente de vez em quando. Não tem tanta coisa na brinquedoteca, mas geralmente tem alguém para olhar as crianças e isso ajuda.</li> </ul> Ainda não testei, mas recebi recomendações</h3> Hamburgueria Brooks</a></li> </ul> Serviços</h2> Corretores de imóveis</h3> Tive uma ótima experiência comprando minha casa com a Tieli Cardoso</a> e o Jefferson Bonafé</a>. Ambos são ótimas pessoas e fizeram um trabalho legal para encontrar a casa que a gente precisava. O processo demorou meses até encontrarmos uma casa que atendia a nossa necessidade. Vimos dezenas de imóveis (mais de 30) e eles foram super atenciosos. Painéis Solares</h3> Fiz a instalação de painéis solares na minha casa com a Solemax</a>. O processo de orçamento, instalação e pós venda foi/está sendo bem bom. O preço deles é um pouco mais caro que os outros que eu cotei, mas gostei da qualidade do material e do serviço. Pet shop</h3> Noah pet care</a>: Levamos o nosso cachorro para banho e o serviço foi bem bom. A localização ajuda também, dado que é bem perto do parque ecológico.</li> Pet Peron</a>: Gostei bastante do serviço de banho deles e do atendimento. Apesar de não estar usando sempre, voltaria com certeza.</li> </ul> Veterinário e exames pet</h3> Clínica veterinária Mundo Azul</a>: Nosso cachorro precisou de uma cirurgia e fizemos tudo com eles. Ótimo atendimento e tudo muito fácil. Processo super tranquilo.</li> </ul> Saúde</h2> Clínicas e vacinas</h3> Pro-medica</a>: Eles tem várias especialidades. Eu passei com a otorrinolaringologista e gostei do atendimento tanto da clínica como da doutora. É um pouco ruim de marcar, mas fora isso funcionou muito bem.</li> ImunoVacin</a>: Fomos lá dar vacina nas nossas crianças e a experiência foi ótima. Também falam muito bem dos médicos dessa clínica, sempre tem indicações das pessoas que moram por aqui. Por enquanto, só gente falando bem.</li> </ul> Para crianças</h3> Pediatra Dra. Ana Paula Rodrigues Massa: A dra. Ana Paula é incrível. Ela atende em clínica própria na Torre Medical. Ela tem bastante experiência e sabe lidar muito bem com as crianças. Passei com os meus filhos com ela e tem dado um suporte bem próximo para nós em todo o processo.</li> Pediatra e Alergo Dra. Paula Beatriz</a>: Atende na Clínica ImunoVacin, que é ótima. A Dra. atendeu a gente muito bem para avaliar as alergias dos meus filhos. Só elogios.</li> Dentista Dra. Estela Amstalden</a></li> </ul> Para Adultos</h3> Dentista: Dr. João bosco</li> </ul> Exames</h3> Exames de Sangue</h4> Confiance</a>: Meus filhos fizeram exames de sangue lá e o processo foi bem tranquilo. Cobre vários convênios.</li> Centrolab</a>: Minha esposa fez exame de sangue aqui e o processo foi bem tranquilo. Cobre vários convênios.</li> </ul> Exames de imagem</h4> MRI</a>: Ainda não visitei, mas recebi indicação de alguns médicos.</li> Diagmed</a>: Fiz com meus filhos um raio x e o resultado não foi dos melhores. Dito isso, o resto do processo foi OK. Eu vou dar outra chance para eles.</li> </ul> Travel (without kids) Unknown — Wed, 01 Jan 2020 00:00:00 +0000 I have a long list of places I visited</a> and if you look at the descriptions you will notice a pattern on how I usually travel. I decided to write this one, so I can refer to it most of the time. Here I'm going to describe how I like to travel when I'm alone or with my wife. I currently have 2 kids and travelling with kids is a totally different kind of trip that I will describe in a different post. Gear</h2> I'm an adept of the onebag</a> travel, so I mostly use only one backpack to travel. As I'm writing this post, the Minaal travel and the PeakDesign Travel are our travel gear. I totally recommend both of them, but if I had to choose one, it would be the PeakDesign travel. Schedule</h2> I usually have a very packed schedule when I'm travelling and the pattern is mostly the same: ~8:00 Wake up and get ready for the day. Have breakfast before leaving if available or just stop somewhere for some coffee.</li> ~10:00 Going somewhere I want so visit</li> ~13:00 Stop for lunch. Most of the time, I try to not spend that much time on restaurants.</li> ~14:00 Seeing more stuff</li> ~19:00 Dinner time</li> ~20:00 Depending on the season and how tired we are, we go for some nightly sightseeing. At night, some structures are quite beautiful.</li> ~23:00 Going to sleep</li> </ul> It's not strict, but that's usually the structure I follow. Going back to the hotel/hostel/BnB during the day is not something I usually do. I also tend to eat in places with decent toilets because it's an important part to make this whole plan work Free Walking tour</h2> I'm a big fan of walking everywhere. If possible, I would totally avoid any kind of transport and will go walking. It's common for me to have 25k+ steps registered on my watch in one day while travelling. Because of that, I discovered "Free" walking tours. They are not actually free, but it's a Pay what you want kind of tour, and I really enjoy it. Every time I arrive to a new city, I try to book a walking tour because it is cheap, fun, and gives me a bunch of information to see the city in a new way in the next following days. You also get some bonus information on places to eat from someone who actually lives in the city. I have so many learnings that I got from these tours. Just to give some examples: Simbols spread over the city have meanings. On the next following days I will spot most of them and understand why they are there.</li> Local restaurants that local people go, not tourists.</li> General tips like: Don't enter a restaurant if there are pictures of food in front of it, there's a good chance it will be a tourist trap.</li> Unwritten rules about doing safe travel on that city.</li> The list goes on. I highly recommend starting your trip with something like this.</li> </ul> Review of On the Shortness of Life Unknown — Thu, 26 Dec 2019 00:00:00 +0000 Book: On the Shortness of Life</a> by Seneca. Rating: ⭐️⭐️⭐️⭐️. A short and good book. After reading Letters from a Stoic</a>, I got the recommendation of this book as well and it was worth listening to it. This book makes me think about the way I'm living my life and how I'm using my time (not focusing enough?). If you want a quick and meaningful book, pick this one. :) Here are my raw notes about the book: Life is short but it's long enough to do great things if it's well-invested</li> For how many the throne of clients leave them no freedom</li> Everyone is wasted for the sake of others</li> No one wants to distribute their money but so many are fine with distributing their time</li> How many robbed you of life when you were not aware of what you were losing?</li> Who can be above him, which is above fortune?</li> It takes a whole life to learn how to live</li> No one pursuit can be followed by a man who is busy with many things</li> No one sets a value on time but they would give anything they have to receive more time in case of illness or capital punishment</li> If you need to be told when to eat, you're not totally free — 💭 I'm thinking about that since I have my own eating routine. There are specific times for everything. It doesn't matter if I'm hungry or not, I will crave food. Am I free? (Rhetoric question to myself)</li> If you see someone using office clothes, don't envy them as they spent a big portion of their lives invested to be there. — 💭 it's a bit out of context as I think it's probably related to politics (e.g. you have to be old to be a senator), but I think it's valid to some extent today</li> </ul> Review of Digital Minimalism: Choosing a Focused Life in a Noisy World Unknown — Fri, 20 Dec 2019 00:00:00 +0000 Book: Digital Minimalism: Choosing a Focused Life in a Noisy World</a> by Cal Newport. Rating: ⭐️⭐️⭐️⭐️. I'm a big fan of the Deep Work: Rules for Focused Success in a Distracted World</a> book and this is another great book by Cal Newport. This one is not life-changing as Deep work was for me, but it brings great insights into technology in general. I'm not a big fan of social networks in general, they are mostly a waste of time in my point of view. Cal shows something even worst about them in this book, which is how companies explore your attention. This is something I saw in many other books already, but this one goes a bit more deeply on the topic. It makes me reconsider many of the apps I still use. Currently, I'm a hard user of the DnD (Do not Disturb) mode of my phone, so I receive almost no notifications. From time to time, I disable the DnD mode and there they are, many notifications of things "I have to see". This will be the next step of my quest, remove the apps or at least silence them all. This book is great and I know MANY people that would benefit from the tips here. The main problem is that these people do not care much about spending their time on these apps. With that in mind, I will still recommend it to some or at least try to exemplify the problems, maybe they will change their mind (or maybe not, and it's fine). Here are my raw notes about the book: The biggest companies in social media should admit they are tobacco sellers of our time, selling addictive drugs to children in the form of likes</li> Mentions to a book called Irresistible</li> Unpredictable positive reinforcement triggers our will to do things more (receive likes)</li> Social networks exploit our craving for social approval. The number of likes shows the group approves what you're doing</li> Digital minimalists are OK with losing small things to focus on others that make their lives good. e.g. the small advantages of Facebook don't pay for the overall problems of using it</li> Choose the right technology and use it in a meaningful way that goes in the same way as your goals</li> Clutter is costly. Many apps may have such a negative effect that surpass the positive effect of apps isolated</li> One should not only consider the financial return of things, but also the amount of lifetime invested</li> While considering the advantages of social media, take into account the time you're spending to have that advantage. Does it worth it? Is it the best way to achieve what you want? Be deliberate about it.</li> Many people limit Netflix to social events like watching with their partners — 💭 that's exactly what I do 🤔</li> Intention trumps convenience</li> During the digital detox, remove every app (or game) that is optional for your life. It will take 30 days, and you will have time to reevaluate their usage. Break the habits of checking these apps from time to time and fill this time with something meaningful. After 30 days, reevaluate from scratch if you really need it.</li> Players of rock, paper, scissors usually exploit the body language of their opponents to adjust their moves accordingly. It's not about luck or statistics as everyone expected</li> Since we're a baby, our brains use the non-focused time to think about social things. It's part of who we are. It happens even when we don't even know what social is (the same region of the brain is activated with the same patterns)</li> The usage of apps like Facebook can increase or decrease your happiness. For the general public, it reduces happiness overall and has a strong correlation with loneliness. The increase in happiness only happens in small doses, when interacting with people we know. These interactions are not so good as face-to-face interactions, but they let us think 'our social interaction is done.'</li> Invest your time in conversation (real-time, in-person when possible), not connections (Facebook post, online chat, Instagram likes, etc.). At first, you will lose contact with many people, but in the end, you will be strengthening your relationship with people that matter for your life</li> "I remember the anxiety of calling my friends and not knowing which family member will pick up and how they would feel the intrusion."</li> Trade text and likes to a real-time conversation. It's ok not to be "on-call" 100% of the time.</li> Reserve periodic time for meaningful conversations with people. It is good for your productivity and relationships (much better than texting or social media) — 💭 This is also something I do. Not much during the pandemic tho.</li> Board games are one of the things that promote intense social activities, much more than playing call of duty online</li> "Crossfit is like a religion ran by a biker gang." — 💭 LOL</li> Schedule time for "useless" activities like mindlessly watching Netflix, tap social media apps, etc. During the rest of the day, stay "offline."</li> If you don't find the social you're looking for, create your own</li> If you're going to use social media, avoid their mobile apps as they are the major source of distractions</li> </ul> Review of Peak Performance: Elevate Your Game, Avoid Burnout, and Thrive with the New Science of Success Unknown — Sat, 07 Dec 2019 00:00:00 +0000 Book: Peak Performance: Elevate Your Game, Avoid Burnout, and Thrive with the New Science of Success</a> by Brad Stulberg. Rating: ⭐️⭐️⭐️⭐️. A great book. I felt like it's a compilation of some good books I read in the past years. It was not a life-changing book for me but it was great to review the important info I collected in the past years. I would totally recommend this book as the first book for someone looking for performance improvement. Here are my raw notes about the book: He was not going out to meet girls at night. He was not an average teenager. Of course, average teenagers don't run 4 minutes miles</li> Like many other good performers, this guy was a combination of good DNA and hard work</li> His friends often joke he was anti-fun (because of the amount of hard work every time). He was grinding but was enjoying it too.</li> Americans will continue to work more and take less vacation</li> Considering all the work done after hours and the "always-on" culture, Americans work around 47 hours a week</li> DNA also plays a significant role in peak performance</li> The overtraining syndrome is commonly found in artists because of their passion and perfectionism. Overtraining is when your body doesn't want to train anymore but it's being forced to, so it starts to throw some toxins</li> The right amount of stress + the right amount of rest = growth (not just for muscles)</li> Sleep is very important for peak performance — 💭 not a surprise for those who read Why We Sleep</a></li> Insert periods of restoration after intense activity.</li> Being on a diet will probably create some fatigue as you have to use your willpower not to eat some things</li> Prepare your environment. It's incredible how your environment influences your ability to do things</li> Failure and struggle is a good way to learn. If you want to grow, you have to see stress as something positive</li> Growth comes at the point of resistance. Only seek support after you struggle a little bit</li> Good stress is when you find yourself a little out of control but not anxious</li> You should look for tasks that are a bit over your skills so that you can grow</li> It's not just experience that makes people experts. Experience is not the top measure to distinguish top performers. Experience and expertise do not go hand by hand</li> It's not time practicing that makes the difference but time practicing deliberately</li> Be fully present to practice deliberately. Don't multitask for anything</li> According to research, the best way to remove temptation is to get the objective out of view and reach</li> People can't engage in deep activities for more than two hours — 💭 That's the case for me and also a reference to Deep Work: Rules for Focused Success in a Distracted World</a></li> Working 50-90 minutes distraction-free seems to be the key for peak performance</li> Deep work is a practice that has to be cultivated over time</li> Our minds play an important role in how we perceive food and satiation. It's not just related to the properties the food has</li> Children with a growth mindset progress significantly faster than their peers</li> If we consider stress as something positive and use it as a challenge, we can thrive even in these situations</li> The sensations you feel before an event are neutral. Your mindset influences how you will feel it</li> Stress at the right doses help stimulate the body</li> Meditating is one way to turn off the stress response related to a particular event. Meditators tend to have better control over how the amygdala reacts to an i.e. painful stimulus</li> A good way to overcome stress is by having a calm conversation with yourself. The pain and stress are normal, and you will overcome it soon. Do not think about how big the pain is and how much you still have to go through</li> Do breaks between tasks. The higher demanding the task is, the longer the break.</li> Rest is sometimes harder than training, and it's almost that important</li> Walking breaks help to regain focus and have good ideas. Walking lets us free enough to wonder about things but not let the mind wander or focus on different things</li> Mindful meditation is recommended regardless of doing breaks and small meditation throughout the day</li> Have some time with friends after a hard day of work; it makes you feel better. Happy hour is not recommended, that's where people go to complain about work</li> A mid-day nap can be beneficial if it's less than half an hour, but it is not a replacement for the missing time slept at night — 💭 This is also mentioned on When: The Scientific Secrets of Perfect Timing</a></li> The best way to find the right number of sleeping hours for you is to take 10 to 14 days and go to sleep when you want and wake up by yourself. Take the average sleep time, and that's it.</li> Use the bed just for sleeping or sex. No TV, laptop, or cellphone while on the bed, just a paper book maybe.</li> Make your room as dark as I possible</li> Take care of yourself. Fatigue is just an opportunity for growth, broke is just broke</li> Time your vacations after high-stress periods. Totally disconnect from work, both physically and mentally. Use your vacations to do activities you find relaxing and restorative</li> You should not wait to get "in the zone" you should create it — 💭 That's a good advice. I'm trying to do that nowadays but it's not that simple. Music usually helps me.</li> Mood affects performance. Build a routine to get in the right mood before starting the task</li> Prepare your environment, so it automatically triggers what you want to do. Keep only objects that will be useful for your task</li> Use the same things on your routine; it will help to signal to your brain that you will soon be in the mood (habit cue) — 💭 It's also mentioned on The Power of Habit: Why We Do What We Do in Life and Business</a></li> Build your life around making decisions that matter. Is the traffic jam important for you? If not, try to choose a place to live where you can avoid it. Are clothes important for you? If not, choose clothes that don't make you think about it. It applies to anything. — 💭 OMG, that's so true. I do that all the time.</li> Our will power is limited, that's why it's easier to do things in the morning.</li> We have limited energy and should devote it only to things that matter.</li> Always exercise at the same time of the day, so you don't have to even think about it — 💭 That was key to my exercise routine</li> Protect your peak time for the most important task of your day</li> Don't fight fatigue; use is to rest and let your mind wander. It's a time when you may have great ideas</li> Motivation is contagious. The feeling of the group is something that affects performance (studies made on squadrons show the least fit person of the group influences the whole squadron to be better or worse)</li> If you're constantly fighting the mindset of those around you, there's a big chance you will be dragged down.</li> A chain is just as strong as its weakest link</li> Great performers are not consistently good; they are good on being consistent</li> Everything we discussed until now is about showing up and being the best at what you do. People show up even when they don't feel like to.</li> When you set to do things greater than yourself, you can do amazing things (lift a car in an accident situation, etc.). It probably happens because we let our ego aside in these situations. Our ego protects our body to not give our full potential, as it may be risky for ourselves.</li> Only when we transcend ourselves, we can achieve our full potential (by removing our ego from protecting us)</li> Are you willing to give yourself for a greater cause? For all great performers we interviewed, the answer was a YES</li> Making part of something bigger is what gives you motivation when you're in a bad situation. "I make art to make people smile, cry, and connect to the Earth". — 💭 I would also say I'm currently making software to help people be more productive and have a better life :)</li> Link your goals to something greater than yourself to have a better performance</li> Add values and purpose to your life (or write them down, if you already have them) — 💭 I should read more about the examples are given here; it's not easy to take notes by listening to audio. I will use the text version as a reference</li> Living up your purpose is the best thing in the world</li> Out of sight is out of mind</li> Take more breaks of at least 5 minutes. Do the dishes, listen to music, go for a walk, etc. Do things that require little to no concentration. You may have an ah-ha moment during your breaks</li> Don't devote brain power to gossip, politics, or worrying about what people think about you — 💭 ❤️</li> </ul> Review of Born Standing Up: A Comic's Life Unknown — Sat, 23 Nov 2019 00:00:00 +0000 Book: Born Standing Up: A Comic's Life</a> by Steve Martin. Rating: ⭐️⭐️⭐️⭐️. I got a recommendation for this book on Quora. I don't even remember what was the question about, but I usually mark some books to read when I get these "books you should read" questions. I had low expectations about this one and it surprised me. :) It was great to follow Steve's career from a broke comedian to a famous one. The struggles to start, the glorious days, and the decline. Here are my raw notes about the book: If the light is thrown on the spectators, they don't laugh</li> "Once she told the ventriloquist to get his dummy closer to the microphone"</li> I was sad one day and mentioned that my high School girlfriend broke up with me. He said: "Oh, that will happen a lot"</li> When doing standup, the jokes are now about you. It's not a guy that entered in a bar, it was you.</li> Most jokes have a punchline and cues. Sometimes there are cues as gestures</li> Do you mind if I smoke? No! Do you mind if I fart? — 💭 LOL</li> How many people never raised the hand before?</li> There was a time I couldn't convince the audience that the show was over. They were thinking it was all part of the show — 💭 LOL</li> "I'm a celebrity now. Normal rules of social interaction no longer apply"</li> </ul> Contributing to Rust Unknown — Fri, 22 Nov 2019 00:00:00 +0000 I'm involved with the Rust community for a while now. I'm one of the main organizers of the Rust meetup in São Paulo</a> and also the Rust conference in Latin America (Rust LATAM)</a> for more than one year now, but did not contribute to Rust source code yet. This post will show the step by step I did to submit my first pull request to the Rust compiler. If you want to go straight to the step by step, without any introduction, jump to My step by step to the first contribution</a>. The dream</h2> I don't know about you, but I always wanted to contribute to core things. I still want to have a commit on the Linux kernel someday, and it's not the first time I try to contribute to a programming language. I read the kernel source code multiple times and also read their contribution guides, but it's not simple to contribute. It's hard to find issues you can understand, reproduce, and compile. It may not be true for people out there, but it was my personal experience. I also tried to contribute to the Ruby programming language. I was working with Ruby for many years, so I decided to read its source. I didn't find the code easy to follow, and the issues are not easy to find and reproduce. For Ruby, it's even worse, since some things are still in Japanese, especially the discussions. The language community is not very accessible to contributions like the rest of the community. These paragraphs are not to say bad things about these communities. I still love Linux and the Ruby programming language. I just want to show my previous attempts and what went wrong. 😉 The Rust scenario</h3> Different from the Linux kernel and the Ruby programming language, the Rust programming language is implemented in Rust itself (instead of C), which makes things even better. 🙂 The community and contribution guides are both awesome. You can feel the enormous amount of work the community puts on documenting stuff so people can find it easy to fix small things or even suggest and implement significant features. The whole process of how the community organizes itself is very open and encourages everyone to take part in it. This is not something I found on my previous attempts of contributions. How it started</h3> At Doist</a>, we (speaking about my team here) try to encourage people to learn new things every week. You should reserve some time to try new things and bring some knowledge back to the team. If you don't book work time for that, you will probably overwork or never have time to improve your development skills. Every week we're naming someone to be responsible for describing what he/she learned during our next weekly meeting. It doesn't mean this is the only person that has to learn something, but at least one will be responsible for describing to the rest of the team. During the past week, I volunteered to take some time to learn something and report back. What I have in my schedule for months now (I would say more than one year) is to contribute anything to the Rust compiler. It doesn't matter what the contribution will be, but it has to be something meaningful and change the compiler in some way. With some work hours reserved (around 3 hours of work during the week) and some of my free time, I was ready to start! My step by step to the first contribution</h2> PS. I will link to a lot of documentation here, it's possible that they will change the links and it will break, but hope the whole context helps if the links are not 100% functional after some time Understanding the structure</h3> The first step was to read the CONTRIBUTING.md</a> file. There's a lot of good stuff there. Seriously, it seems obvious, but it's not like other projects I tried and gave up quickly, it shows/points to everything you need to know. If we refer to the build system section</a>, we will be quickly introduced to the build script (x.py</code>) and to a complete guide about how the compiler works</a>! :) From there, you will understand how the compiler works and how you can use the python script to build a small piece of it, which is what you want to be able to fix a bug. Finding the issue</h3> I'm particularly interested about the diagnostic issues</a>, so I reached out to the guy who is more familiar to this part of the codebase (@estebank</a>) via Zulip</a>, which is currently the tool of choice for communication with the compiler team. I met Esteban at Rustconf</a> and Rust LATAM</a>, so it was easy to introduce myself (again). Everyone I talked to until now was very receptive to help when you're polite (of course) and asking for help, even if they don't know you, so don't be afraid to reach out to people. Esteban described which labels would be suitable for my first issue (in this case, d-papercut</code>), and I started to read one by one to pick mine. After some time, I decided to investigate an issue about the suggestion for the #[repr = "C"] syntax</a>. The first compilation</h3> The issue I chose mention a .stderr</code> file on the codebase</a>, which is a great way to start. :D The first thing I did was to look for one of the strings I found there (the text "must be of the form</code>") and change it to something else. I changed it to must be of the whatever</code> and referred back to the documentation on how to build the compiler. As a side note: The way the compiler is compiled is very interesting. It has three different stages. It downloads the beta compiler to compile itself (Rust is written in Rust, remember?), and then it uses the generated compiler to build the compiler again against itself. :) (there's much more, but I recommend reading the official documentation if you're interested ;) ). After trying some commands to build the repository and get used to the time it takes to compile (and how to make the compilation faster by compiling parts of it), I got my first version of the compiler and was able to compile a sample program. I have to say that it's very satisfying to see the change you did there. It doesn't matter if it's just a string. It proves to me that the first step is done, and it's realistic to continue. o/ Now that I can build the compiler, I can get back to the issue and modify the mentioned test. Testing the compiler</h3> We will now use the rustc documentation</a> again to understand how to run the test suite for the compiler. The documentation helps to understand how the testing organization and infrastructure works. It also shows the various types of tests you will find and how to run them. In my case, I had to run the UI tests of the compiler, so I could run it using the x.py</code> script just like I do with everything else: ./x.py test --stage 1 src/test/ui</code></pre> PS. I will not go into the details of the code I used since you can refer to the documentation I linked and get a much better and detailed explanation. While trying to understand how the testing infrastructure works, I found a problem with the documentation, so I submitted a PR to the compiler doucumentation</a> and it was accepted. 🎉 Now, getting back to the issue. When I ran the test command, it shows me that I now have a broken test, since I changed the word form</code> to the word whatever</code>. \o/ So, let's first fix the test to have the behavior I wanted. In this case, I want to recommend #[repr(C)]</code> to everything instead of a statement that is not valid. By doing that, the editors can suggest valid code instead of just a tooltip with and list and ...</code>. Now that I have a broken test, I can checkout</code> the code file and start looking for the file to change. Understanding the code and changing what's needed</h3> This is the part where we should be more used to. When I say more used to, I mean it's more related to our day-to-day job, whatever it is. It's just another codebase with a bug that you have to find out. 😉 Let's start debugging it function by function and understanding which code is being called. We will do that until we find the piece of code that has to be changed. While you're going up the stack, you will probably find many other things you have no idea how/why they are there. In some cases, you may see features of the language that you're still not familiar with, so you may also take some time to learn those to continue your journey. That was the case for me with macros. 🙂 After some time, I finally found the place I had to change, and it was simple for this particular case I was trying to solve. Creating the pull request</h3> To create a Pull Request, we can refer to this section in the Rust documentation</a>. I used that to create mine and mention Esteban. There are some bots to help the community to take care of managing the PRs, so we (as a community) have many powers to ask for reviews, approve PRs, create a queue of PRs to merge, etc. To mention someone to review, I used the r? @username</code> function of the rust-highfive</a> bot, so it can assign the person who is knowledgeable on that part of the codebase (@estebank in my case). After creating the PR, the Rust language infrastructure will run the tests (it was Travis before, Azure pipelines currently, and may change to Github actions in the future) and report back in the PR. After some time (~2 hours), I got the report that I broke the build with my changes (🤦) because there were other tests in a different part of the code, expecting that message as a diagnostic for the [repr = "C"]</code> syntax. I checked the code again and just fixed the test. PR and discussions</h3> As usual, there was some discussion about the change. The PR usually stays there for some days until one of the maintainers have enough time to take a look at it and decide if it's worth changing. The discussions usually happen on the PR itself, but in my case, there were some discussions with Esteban via Zulip, as the change was straightforward, and I had some questions. It turns out that my change only partially fixes the issue because it will need something better designed for this case. The idea is to suggest the right repr</code> for the context of the code. This change will take much more knowledge (and time 😅) than I have now. Fortunately, the Rust team found the change to be valuable enough to merge in, even if it doesn't fix the issue altogether, so the PR was approved </a>! After the approval</h3> When your PR is approved, the @bors</a> bot will add it to the the queue of PRs to merge</a> and will eventually be merged to the master branch. </a> You will also be added to the Thanks page</a> as you're now part of the Rust repository with you commit 🎉. Next steps</h2> I like to do it in baby steps. I planned to try something simple, so I could understand the basics of contributing to the compiler. It's now done. 🙂 Now that I (and hopefully, you as well) understand the processes to contribute and have the setup to do it, I can go to the next step and try more issues. The plan is to focus on the diagnostics part of the compiler (which is the part I like the most) and solve small issues that may have a high impact on how the developers are interacting with the language. When I feel comfortable with the small issues, I can look for something bigger... but... baby steps. 😉 Review of How to Be Free: An Ancient Guide to the Stoic Life Unknown — Sat, 16 Nov 2019 00:00:00 +0000 Book: How to Be Free: An Ancient Guide to the Stoic Life</a> by Epictetus. Rating: ⭐️⭐️⭐️⭐️. A good book. It seems like a summary of the whole enchiridion. After reading Seneca, I decided to try Epictetus. These books are usually very dense and require some time to think about, so I decided to not go with the long form of the enchiridion. I do not regret it; it was a good reading/listening. Here are my notes for this book: Epictetus was born a slave but died a free man You are enslaved when you set your mind to any impediment or if you attach your well-being on things that depend on others Accidents happen, and you have no control over them. A friend may die or you may not be accepted for a job, etc. You have control over how you react to the situation, improve your self-control and patience, etc. At humans, we can try to understand things that happened and what possibly caused them, but there's no reason to complain Epictetus insists that we confront our impressions, especially the ones that disturb us When you desire or are averse to something, you treat it as a big deal. Epictetus recommends to avoid desire and accept what comes If you desire things that are not up to you to get, you may be miserable for not getting it It's not things themselves that upset people, but their opinions about things Instead of blaming someone else when you fail or blaming yourself, blame nobody. You you want to accomplish something, don't be afraid of being foolish and don't try to be an expert. If people think you are somebody, distrust yourself. If you want to be truly free, wish for nothing, especially for the things that are not up to you If you're looking for external approval when you do something, you lost your way. Be the one you want for yourself and people will see you as such Do you want to do something? Then analyze the project from start to finish, not just the outcome. If you're going to be an athlete, think about the training, strict diet, etc. You should remove the good or bad label of things that are not up to us, otherwise, you will be blaming the gods for the outcome If you think it's worth doing something, don't be afraid of people seeing you doing it. If what you're doing it wrong, just don't do it. If it is right, why to be concerned about what people will say? Don't say you're a philosopher or discuss your philosophical point, just act like one Nobody can take my Principles from me Review of Letters from a Stoic Unknown — Fri, 08 Nov 2019 00:00:00 +0000 Book: Letters from a Stoic</a> by Seneca. Rating: ⭐️⭐️⭐️⭐️. I was expecting a bit more about this book but I'm sure it is just a problem with my expectations. The book is a collection of letters from Seneca to Lucilius, and that's exactly what you should expect from it. Seneca was a wise man and these letters contain great pieces of advice. Many of these advices are still valid today, but some makes much more sense when you consider the whole context in which Seneca was at the time. I decided to read this book because of Stoicism but finished for other reasons. One of the reasons is the description of true friendship. If you want to read more about Stoicism, I recommend reading A Guide to the Good Life: The Ancient Art of Stoic Joy</a> instead of this one. If you already know Stoicism and want to understand what Seneca has to say about it, you may enjoy this one. Here are my raw notes about this book I don't regard a man as poor if what is left it enough for him</li> Everywhere means nowhere. If someone lives the life traveling, he/she will end up with many acquaintances but no friends</li> It's not the man who has too little that is poor, but the man who always craves more</li> If you consider someone a friend and you do not trust him/her as you would trust you, you're probably mistaken</li> After a friendship is settled, you must trust. Before a friendship is formed, you must pass judgment. You should not judge someone after making this person a friend, but making him/her a friend after he/she pass your judgment.</li> We suffer from things in the past and from things yet to come. Memory is a blessing and a curse</li> Sometimes sick man is congratulated because they can recognize they are sick</li> You should go for the scene of action first because the man put more faith in their eyes than their ears</li> If knowledge should be given to me in a manner that I could not share it, I should refuse it</li> No good things are worth possessing without friends to share it -- that's interesting. Is it true? I believe the definition of a friend here is broad, and we can also add family and wife/husband to the list. In this case, it will make sense to me.</li> I began to be a friend of myself. Such a person can never be alone. --</li> </ul> Review of So Good They Can't Ignore You: Why Skills Trump Passion in the Quest for Work You Love Unknown — Fri, 25 Oct 2019 00:00:00 +0000 Book: So Good They Can't Ignore You: Why Skills Trump Passion in the Quest for Work You Love</a> by Cal Newport. Rating: ⭐️⭐️⭐️⭐️. This is the kind of book you read and think: "I would love to have read this when I was starting my career", as you have seen a lot of what he describes during the past 10 years. I'm glad that I did most of what he mentions here, and I can say it works. It's great to look to your career in retrospect and see that you did a big bunch of what this book mentions but without any preparation, just because "it seems the right thing to do". The book is a bit repetitive and could be much smaller. The ending looks like a filler to make the book bigger. If you're thinking about what to do with your career, this book may be a great fit for you. Here are my notes: Follow your passion is not very good advice when looking for a career The importance of ability. You need to be good at something to expect a good job. There are many examples of well respected but miserable workaholics to support this argument Life is to short to do what "you think you have to do." Steve Jobs was not passionate about technology or entrepreneurship before Apple. He was seeking for illumination one year before. His work did not come from passion, but from a break of other things he was doing -- hm, that's weird. For me, this is when he found his passion A Canadian research shows that most of the passions people have are not related to work and most likely couldn't be (dance, hockey, etc.) Passion may be a side effect of mastery -- hm, that's an interesting argument, and I tend to agree Working right trumps finding the right work "Follow your passion" works for some people, if course. It's not just good advice for the majority because of that. Passion mindset: what value your job offers you Craftsman mindset: focus on what value you're producing in your job A craftsman often doesn't care much about business, but for their craft. The Craftsman mindset is crucial in building a career you love Adapt the Craftsman mindset to something you do, and the passion may follow it What makes great work great? Creativity, impact, control (over what you do) If you want something rare and valuable (a great job) you have to have something rare and valuable to give in return (awesome work) Consider these rare and valuable skills as career capital Career capital brings you more options and lets you "buy" the changes you want ( career changes in this case) A guy receives emails from time to time asking about his path. "Everyone wants my job" he says. -- it's interesting because I received some contacts from people who like Doist and wants to know how is it to work there and how to apply The deliberate practice provides the key to excellence in a big range of fields. The difference between experts and intermediate is not just the number of hours practicing, but how deliberate they practiced Reading and replying to emails (or any other communication app TBH) shouldn't take too much time on your day. Avoid doing it whenever possible What kind of market you're competing in? Is it a winners take all or auction? Winners take all markets are the ones that have just one thing to do, and you have to be very good at it (writing scripts for TV is the only way to get to this career). An auction market is where you can do many things to contribute to your career. There are many options to choose on what to be good Find the market you're competing for 2. Define what capital you need to invest (winners take all will have just one) 3. Define a "goal to succeed" 4. Practice deliberately and ask for feedback Deliberate practice is found when you're learning something new and feels uncomfortable about it Control is the dream job Elixir. If you have enough control over what you do, there's a big chance you're going to like it ROW, Results of work. Everything else (time, email checking, etc.) is irrelevant Control requires capital -- that's the whole point of financial independence for me Control is important, but you need to have a rare and valuable skill to give in return If you want to change careers, start building career capital now The first trap of control is not to have something stable to make your ends meet The second trap is when you're valuable enough that it's hard to take your control back from your employers The irony of control is that when nobody cares about you, you probably don't have enough career capital to do anything interesting. When you do have career capital, you will be valuable enough that your employer will resist it. Hobbies are different from your main career. Do things that people are willing to pay for as your main career. How did you grow your business?" Sold one CD, which gave me money to sell two" by Derek Sivers Missions require career capital If you want to identify a mission for your job, you must first get to the cutting edge of innovation To get to the cutting edge, you have to focus on a narrow collection of subjects for a long time Once you get to the cutting edge and find your mission, you have to act big and go for it using the career capital you already have Career capital is needed to identify a good mission Instead of wanting to "have a TV show", start small, build career capital, do something yourself that goes on the direction you want. Deploy small bets that generate useful feedback and succeed step by step Misson is one of the most important traits you can get with career capital You should do something remarkable that people want to spread the word about it. Open source projects are good for that. Sometimes we do things that are not our "true calling" but it helps us to build career capital to find our mission Discomfort when trying to learn things is just like muscle pain after training for bodybuilders: it's a sign that you're doing something right. When you feel uncomfortable, keep concentration and keep studying Having an expensive (or great, doesn't have to be expensive) notebook helps you to be mindful of what you are going to write there. Control over WHAT you do and HOW you do it is the Elixir of the dream job If you go for more control over your work without rare and valuable career capital, you are probably pursuing a mirage A pyramid of career for Cal Newport: mission (of his research) at the top.

Rating: ⭐️⭐️⭐️⭐️. A good book that I will recommend to many people. I was between 4 and 5 stars for this one and decided to go with 4. If there was a 4.5, I would totally go for it. I don't agree with all the ideas presented here but I enjoyed thinking about them and seeing some different perspectives on them. There's one sentence in this book that I'm saying to some friends for a while: "If you don't like the way the world is going, realize that there are many people out there thinking just like you. Turn down the TV, look around, and organize". The current state of many people is to read the news and TV and complain about social media. For some unknown reason, this is how they think they are going to do some change. 🤷‍♂ I would recommend this book to everyone who wants to rethink how the world is going and what it may be. It doesn't matter if it's going to happen or not, but you will have a taste of different arguments about that. Here are my raw notes about the book: 6 billion of the world's 7 billion population has a cellphone. Just 4.5 billion have a toilet — 💭 WAT</li> The advertisement makes us spend the money we don't have, on junk we don't need, to impress people we can't stand</li> With the high cost of health care, the life expectancy for many is going down</li> The market provides us with food full of sugar and fat that our health tends to go down</li> The current generation grew listening to: "You can do whatever you want, you're special."</li> Money empowers people and gives them choices</li> The only reason why people are poor is that they don't have enough money. Studies show that when you give money, no strings attached, they mostly prosper</li> When poor people receive money, no strings attached, they tend to work harder</li> The basic income experiment in Canada was shut down after four years, and the data for the experiment was not analyzed. The data was somehow realized many years ago, and the results show it may have been a success</li> Not long ago, democracy seemed to be a utopia</li> A policy for the poor (only) is a poor policy</li> It seems people are more open to solidarity if it benefits them personally — 💭 it reminds me of how the USA let you deduct donations from your taxes</li> If a basic income is proposed for everyone instead of just the poor, it would probably be more accepted</li> Of course, some people will want to work less, but there's overwhelming Evidence suggesting the majority of people want to work, whether they need to or not. Not having a job makes us deeply unhappy</li> Artists may stop doing paid work altogether</li> Basic income will allow the poor to look for jobs where they can learn and grow since the basic will be covered — 💭 what is going to happen to mechanical jobs that (not only the poor) people do? Automation, maybe?</li> Psychology of scarcity. Why the poor make so many bad choices?</li> Investments in education will only help a lot of children when they leave the poverty line</li> Poverty annihilates the future. All that matters is here and now</li> It doesn't matter if there are ten candidates for every job; the problem is always considered to be with the supply, not the demand. The candidate needs to be better</li> Social services expect people to show their shortcomings instead of their strengths, or they may have their benefits cut. It helps to keep people trapped in poverty</li> The GDP is blind to many things. One good example is technology advancement</li> GDP also benefits from wars, drug abuse, gambling, environmental pollution</li> As the writer, Kevin kelly says: Productivity is for robots.

I expect to have much more creative things popping out as work</li> Our ancestors were not richer but certainly had more leisure</li> What once was categorized as leisure is work today (art, sport, care, etc.).</li> We are not against the workweek; the idea is that the poor (and others) will be able to do more meaningful work</li> When people with a reasonable salary are offered if they want to double the salary or have more time off, they opt for the time off</li> Work is the refuge of people that have nothing better to do — 💭 I'm not sure if I agree with that. Work is awesome; you just have to find the work you love</li> The richer we get, the expendable we become since we don't contribute with tangible things to society</li> Banks need people much more than people need banks</li> Studies show that countries with more managers are less productive — 💭 what a surprise! LOL</li> Half of the managers interviewed in a research say their work is meaningless and many of them don't feel connected with the company mission</li> Higher taxes will get more people to do useful work. Just tax people who have a lot of money and are not contributing with tangible things to the society (example: transaction fee for high-frequency trading). It would not give us all a big share of the pie; it would also make the whole pie to grow bigger as those people would go out to become teachers and engineers</li> Higher taxes will reallocate people to professions that bring something useful for the society (to do useful work) — 💭 how useful is HFT? I just realized it's useless :(</li> Instead of thinking about what we need to make a living in a bullshit job in the future, we should think about what skill we WANT to have to make a living</li> If we start to shape our education to what we want the market will adapt — 💭 I do not buy that. There a (big IMO) chance that we will have a lot of people that will not be able to do something useful and places needing people to do useful work but not having qualified people</li> In the future, we will have two individuals per company: a man and a dog. The man to feed the dog and the dog to not let the man touch the equipment. — 💭 LOL</li> Progressive tax based on income would make more equity. We have to save capitalism from capitalists</li> The future is already here; it's just not evenly distributed</li> Borders are discriminatory.</li> In the past, when the border with Mexico and the USA were not so closed, around 80% of Mexicans came back home after tome time. Now that the US spends a lot of money to guard the borders, not so many Mexicans that enter the country come back, as it's hard to go through the border</li> We tend to seek information that confirms what we currently believe</li> People are most likely to change their ideas if y;u confront them with disagreeable points as direct as possible</li> We usually don't vote for ourselves only, but for the group, we want to belong to — 💭 of course, we are not considering the fact where politicians pay people to vote for them...</li> What is the value of free speech when you don't have anything valuable to say anymore?</li> Basic income, world without borders, 15 hours workweek.

The city has a hipster vibe, and I like it. I'm writing this in 2023, so it's been 5 years since I was there for the last time and my memory will totally fail me in many aspects, so please take my recommendations and descriptions with a grain of salt. The things I enjoyed the most was actually walking around the city. 🙂 Stay</h2> In 2015 I stayed in the Hotel Eastlund. I have nothing to complain about the place and their service. It was paid by the company, though, so I have no other info about price or anything. In 2018 I stayed in the Northwest Portland Guesthouse. The experience was OK, just a bit far from most of the things I wanted to visit. Airport</h2> The PDX airport was quite nice for what I remember. I didn't do anything fancy in any of those trips. Just got in time for the flight or arrived there and got transportation for the city. There's a train from the airport that takes you to the city center. It works quite well and the price is reasonable. I would totally recommend everyone to use this option after arriving there. I usually travel light nowadays. At the time it was "light enough" as I usually had a carry on bag and it was quite easy to use the train either way. Transport</h2> Both times I just walked around and used the tram inside the city. I found it to be quite good and simple to use. Some friends of mine usually recommend to get bikes to ride around the city. They are mostly everywhere and you can pay using the app. I didn't get that, but I would totally consider it next time I visit. Places</h2> I didn't have much time to visit places in Portland. I was there for work and didn't take many days of vacations after that. Here are some places I visited (and still remember): Ground Kontrol: a bar with arcade games. I had a lot of fun there. It's probably the place I remember the most and would visit again.</li> Portland convention center: I went there for a conference both times and the place is quite good. It's not a place you can casually visit, but I wanted to add this here in case someone is going there.</li> Powell's city of books: Amazing bookstore. Totally worth a visit. I got some interesting edition of Tolkien books from there.</li> Mozilla: I had the chance to visit Mozilla in Portland and it was quite nice to know the office. I have no idea how things are after the pandemic though.</li> OMSI: Museum of science. It would be amazing for kids, and I have to say I found it quite interesting visiting it by myself too.</li> Free walking tour: I did a free walking tour booked at the hostel and it was nice to walk around and know about the story of the city. We did some walking through the streets that inspired Simpsons characters and many other interesting places. I don't have a name to recommend anymore, but I would totally check Guruwalk and look for something.</li> Washington park: Nice park, great rose garden. It was definitely a nice walk around there.</li> Lan Su Chinese Garden: An OK visit. Quite small, but beautiful. I'm not sure if I would visit again, though.</li> </ul> Food</h2> As usual, don't take my food recommendations very seriously, as I mostly don't know what I'm doing. If you want better food recommendations, check Caffo's recommendation for Portland</a>. I visited most of the places he recommended. Denny's: It was quite close to the hotel I was staying and I just remember asking for something for brunch and being full until dinner. 😂</li> Burgerville: Great burgers and beer (for what my friend told me, as I don't really like beer).</li> Voodoo Doughnut: I'm not a big fan of doughnuts, but I had to try it. I would recommend people to try it too, just be ready for a ton of sugar.</li> Lardo: Pretty good burger and drinks. Highly recommended.</li> </ul> My 2019 Productivity Workflow Unknown — Thu, 15 Aug 2019 00:00:00 +0000 From time to time, I receive questions about my productivity workflow, so I decided to write it down here. Keep in mind it's a living thing and may change with time, but what I'm documenting here is what I'm using right now. Tool</h2> As you probably know, I work for Doist</a> for some time now, and I'm a Todoist user since 2007, so the my tool of choice is quite obvious. I love how Todoist</a> brings simplicity to creating and managing tasks. Things become even better when you add filters to the mix. 😉 The organization for my top level projects looks like this: Personal: Anything personal like money, investments, random thoughts, etc.</li> MyCompany: Bureaucracy of having a BR company, things to pay, people to reach, etc.</li> Work: Everything related to my full time job. It's probably the one with more sub-projects and tasks</li> Hobbies: I have many, so I have a project for each. Examples: Drums, MTG, Cardistry, Photography, etc.</li> Me & Wife: A shared project with my wife. Anything we do together we add there.</li> Others: projects I could not fit in any other category. Example: Todoist integrations</li> </ul> Most of these top level projects have have their own sub-projects. Process</h2> I use due dates to guide my life inside Todoist. Every day I open Todoist and find what I have to do during that day. When I have something in mind it goes to my Inbox</code> project. It doesn't matter if I'm at the computer or walking on the street, I just open Todoist and add it there so I can do the triage later. I try to apply the Getting Things Done</a> idea, but my own version of GTD looks like Zen To Done</a> to be honest. The principles are the same in the end, but the methods differ. Both methods say you have to process your Inbox</code> at least once a day, and that's exactly what I do. Every task I add to my Inbox</code> in project on Todoist will be processed and added to the right project with a possible due date so it will pop up in my Today list in the future. It doesn't matter much if I will finish all of the tasks or not, but they are there to remember me what I planned for that day and what is important to keep focused on. If I can't finish at the end of the day I postpone for the next or find a due in the future where this task will it makes more sense to do it. Everything I have to do is added to Todoist. I don't keep anything in my mind because I don't want anything asking for attention when I have to focus. If there's something to do on Monday, I can rest assured that Todoist will notify me about that in the right day and time. Routine</h2> I love routines, but it's important that I'm able to have full control over them, and that's exactly what I have. I built my current routine based on my schedule, my wife's schedule, the times I feel more productive, and other studies I did to myself through the years. Every weekday I have at least 8 tasks that are fixed and define my routine: [06:00] Wake up and prepare breakfast I have some notes on this one. Sometimes I want to prepare a different breakfast and never remember how to do it, so it's there</li> </ul> </li> [08:00] Walk the dog</li> [10:30] Start the deep work session</li> [12:30] Go to the Gym</li> [14:00] Record body data I try to quantify myself as much as possible. This is just a reminder to add my weight to the tracking app</li> </ul> </li> [17:00] Start the deep work session</li> [19:00] Relax after a good day of work</li> </ul> These are the things I want to do. Sometimes people say things like: "You let your task app say what you have to do", but is quite the opposite. I plan what I want for my days and I use my task list to keep me focused on what I want. Some of these tasks trigger integrations that help me get laser focused on what I want to do. A good example is the Start the deep work session</code>, as it triggers the "Focus time" of rescuetime</a> and block sites I consider not productive. Recurring tasks</h2> I have some recurring tasks that are not part of my routine and they are not related to work. It's also important to make time for the things you care about, not just work-related tasks. Here are some of them: Check a Slack group of friends I want to keep in touch</li> Check the Discord of the conference/community I'm currently a core organizer</li> Remember to track my progress on Goodreads and write reviews</li> </ul> Track my reading progress help me to stay on track. Writing reviews help me to retain more information by reviewing it to myself. Filtering to avoid distractions</h2> I use Todoist filters a lot! Filters are very useful to... hm... filter non-important tasks from your current focus mode i.e. if you're doing deep work, you don't need to know your routine. I like to consume books, my average is 30 books a year</a>, and every time I consume a book that mentions productivity I try the method with filters. Let's break down my filters and explain their usage 🙂 Peak, trough, recovery</h3> Peak -- @peak & today & (assigned to: me | !assigned)</code></li> Trough -- (@trough | (!@peak & !@recovery)) & today & (assigned to: me | !assigned)</code></li> Recovery -- (@recovery | @peak) & today & (assigned to: me | !assigned)</code></li> </ul> As you can see, I also rely on Todoist labels to mark the tasks I want to have in each of these chunks. These filters came from the book When</a>. I used the Daily when tracker</a> to check when was my peak, trough, and recovery times: I also use the concept of Deep work</a> described by the book with the same name. This is the reason why I have the task "Start the deep work session" in the morning and at the end of the afternoon. Deep work filters</h3> Based on the same Deep work</a> book mentioned above, I also use @deepwork</code> labels on Todoist so I can filter the right tasks depending on my current mode. If you don't know the concept, it basically tells you to reserve chunks of your day to work on things without distractions. It means: no cellphones, no social media, no chatting, no email, etc. I usually have the following filters as favorites: Deep @ Work -- (today | overdue) & (assigned to: me|!assigned) & @deep_work & ##Work</code></li> Shallow @ Work -- (today | overdue) & (assigned to: me|!assigned) & !@deep_work & ##Work</code></li> </ul> The "Deep @ Work</code>" filter gets all tasks from projects under my "Work</code>" project that should be done today</code> and have the "@deepwork</code>" tag. The "Shallow @ Work</code>" filter is almost the same but it takes everything without the "@deepwork</code>" label. Everything else without this label is considered shallow work. Priority filters</h3> I also have some filters based on the tasks I set priorities, so I can quickly see what should be a priority for my day instead of just reacting to what is going on. It doesn't work all the time because urgent and important</a> things sometimes pop up, but it gives me a clear view of what my priorities are. Here are the filters I have: Priority today -- ``(today | overdue) & (assigned to: me|!assigned) & p1</li> Priority @ Work -- (today | overdue) & (assigned to: me|!assigned) & (p1 | p2 | p3) & ##Work</code></li> </ul> These two helps me when I just want to focus on the work I have to do today. Sometimes I have personal things that are also priority, so I keep both together, but I mostly use the Priority @ Work</code>. Integrations and automation</h2> I mentioned the trigger I have for rescuetime's Focus mode but it's not the only automation I have. Here are some others: Shopping list</h3> I keep a shopping list in Todoist shared with my wife. Every time we see that something is missing and have to be bought, we try to add it there right away. I have the location reminder enabled for Todoist in on my phone, so it reminds me to check that list every time I'm nearby a local supermarket, which happens almost every day because of my daily routine. Every time I check a task, IFTTT sends a message to a group chat in Telegram, informing my wife that it's done so she will not buy it again. Sometimes we forget to check the list, so it's helpful to get a reminder that it was bought already. Weekly snippets</h3> Every week at Doist, we post a list of important tasks we did during the past week and what we plan to do during the next. I add a "@snippet</code>" label to every task I want to report. When a task with a "@snippet</code>" label is completed, IFTTT creates a new task in a project called "Snippets</code>" with the completion date and the task project in the task title. When I want to report that, I go to the "Snippets</code>" project, click on the menu, Export as a Template, and Export as file. I have a note in the same project with a command the does the job of formatting that: cat ~/Downloads/Snippets.csv | grep -v project_note | grep "task," | awk -F "," '/1/ {print "- " $2}'; rm /home/pothix/Downloads/Snippets.csv</code></pre> So I can just post it to Twist</a>. How a typical day looks like</h2> I wake up early (because that's what I want for myself, I don't have to), prepare the breakfast, and take some time to eat and chat with my wife. We try to not waste our time together looking at cellphones. After breakfast I check my Todoist and what has to be done for the day, just to be sure there's nothing pressing for the next 1-2 hours. If it's OK, I take these 1-2 hours for myself. I'm now writing this blog post. ;) After that, the routine I described</a> starts. There are many other tasks that are not part of my routine, so I use filters to focus on what I think fits better for that time. At the end of the day, I postpone my tasks (if any) or just let them become overdue to be postponed quickly via Todoist on the next day. I usually don't have anything pressing from 6-8 a.m. so I don't have to check my plans for tomorrow every night. Final notes</h2> I've been doing this since 2007, when I started looking for a productivity tool and found Todoist. It's a lot of practice to have a working system/process. I used different tools along the way (Remember the milk, Toodledo, Habitica, Thingking Rock, Google keep, and the list goes on) but I always came back to Todoist because I really like it. It's not by coincidence that I'm working for Doist, I think about that since the beginning, but decided to apply for it in 2017. I love Todoist and I recommend it, but keep in mind that it's not about the tool, but your mindset, and how you organize your process. Keep in mind that persistence is important. Your process will certainly fail (as the one I described do), but you will improve it and make it (and yourself!) better in the process. If it's not working, just think about it and adjust it to match your way of doing things. Stay focused and productive 😉 PS: ⏱ It took me 2h27 to write this blog post Review of Moonwalking with Einstein: The Art and Science of Remembering Everything Unknown — Tue, 13 Aug 2019 00:00:00 +0000 Book: Moonwalking with Einstein: The Art and Science of Remembering Everything</a> by Joshua Foer. Rating: ⭐️⭐️⭐️⭐️. I like this book. Learned many things and enjoyed listening to it as a story. I don't think it's life-changing for me, but it brought good insights and some curiosity about how I can improve my memory. I saw some people mentioning that "this is not a book to teach you how to improve your memory". I don't even know why they were expecting that. The book makes no claims that it's going to teach you techniques to improve your memory. This book is about the author's quest to win a memory championship and what he learned in the process. You can learn memory techniques from this book, but it's more of a side-effect than the original goal, IMO. I decided to consume this book after I started to memorize the Mnemonica by Juan Tamariz. It seems Tamaiz's book has many references to this one because of the techniques mentioned here. I first heard about the "memory palace" when watching Sherlock Holmes by BBC. It's a great concept and it makes total sense. When memorizing the Mnemonica, I adapted a story I saw on youtube and the images are what makes it stick. I totally recommend reading this book. The whole story is cool and the techniques mentioned bring many pointers for the geeks. Here are my notes for this book: I can't remember the breakfast I had yesterday but I can remember exactly the breakfast I had many years ago when the 9/11 attacks happened. Why? The Association of words with places, images, flavors, smells, etc. Is the best way to record something in our minds. Sometimes we may miss some of those words by not being able to see it in the place we virtually let them (e.g. an egg in a while wall) Experts see the world differently. They see things normal people don't see. We can store an average of seven things in our short term memory by using a phonological loop (repeating it to ourselves) We don't remember isolated facts, we remember things in context. There's a study with chess masters that shows exactly that by showing valid and invalid chess positions. Monotony collapses time, novelty unfolds it. You can eat healthily and exercise to live a long life but perceive a short one. The full quote (added when writing the review): "Monotony collapses time; novelty unfolds it. You can exercise daily and eat healthily and live a long life while experiencing a short one. If you spend your life sitting in a cubicle and passing papers, one day is bound to blend unmemorably into the next -- and disappear. That's why it's important to change routines regularly, and take vacations to exotic locales, and have as many new experiences as possible that can anchor our memories. Creating new memories stretches out psychological time, and lengthens our perception of our lives." It's important to change your routine from time to time, so you can perceive your life better. Life seems to speed up when we get older because life is also less memorable when we get older The neocortex is not fully formed until the 3rd or 4th year of a child infancy As infants, we lack a schema to interpret the world, so it's hard to store memory properly to be recovered later Natural memory is the one evolution brought to you. Artificial memory is the link to your natural memory. It's like the software (artificial) running on top of the hardware (natural) The method of Loci, aka memory palace, makes use of the artificial memory to store things on your natural memory Akira Haraguchi mnemonic specialist Pi digits (https://en.wikipedia.org/wiki/Akira_Haraguchi) was mentioned The word "topic" comes from the word "place" (greek?). The sentence "In the first place" comes from this memory material. We teach the alphabet as a song because it's easier to remember. Histories have been passed along by bards for generations It helps to do the action you're leaning in a new language, it tends to stick easily To Socrates, the meaning of knowledge is knowing and remembering many things. There's no point in writing down to pass the knowledge along In the past, manuscripts were copied for no reason other than remembering them. The Torah has no vowels or spaces -- WAT In the past, books were not that accessible, so it's better to memorize them as you don't know if you will have access to it again You can't read a page in one minute and expect to remember it for a long time PAO, person, action, object. Think about a person, doing an action, and holding an object. You can combine that to e.g. memorize three cards We all reach "OK plateaus" on everything we do. It's when you move something to autopilot and stop improving Amateur musicians focus on playing songs. Expert musicians focus on training the tedious exercises to improve the hardest parts of songs. Deliberate practice must be hard by its nature The best way to improve typing is to type faster than it feels comfortable and allow yourself to make mistakes so you can learn and improve If not practicing deliberately, even experts will not evolve at a good pace Knowledge is required to acquire knowledge. Sometimes you need a base to understand other things. When traveling, you will miss a lot of things if you don't understand the culture There's a feedback loop in memory and knowledge. One is not required for the other, but it helps. Remembering can only happen if you decide to take notice PS. this is another book that mentions EP's case of memory loss. The nice coincidence of listening to this after the power of habit :) Review of Buraco Analista Unknown — Sun, 07 Jul 2019 00:00:00 +0000 Book: Buraco Analista</a> by Aguinaldo Prandini Ricieri. Rating: ⭐️⭐️⭐️. É um livro interessante se você tiver interesse em conhecer a vida do professor Ricieri. Eu fui a uma de suas palestras alguns anos atrás e achei muito interessante a forma que ele apresenta a matemática. Ainda não participei de um de seus cursos, mas pretendo. Esse livro conta a história dele querendo ser um cientista em Cornélio Procópio. Parece ser uma boa descrição do que é ser um cientista no Brasil no geral pelo que ouço falar de outros cientistas também. O professor tenta contar a história do ponto de vista do seu "eu adolescente", então tem algumas outras coisas sobre as suas incertezas amorosas e descobertas sexuais. As vezes é bem engraçado, mas também desnecessário. Ele toca em um assunto bem polemico relacionado a vida dele perto do final do livro. Achei interessante ele ter publicado isso, ainda mais em 1995. Eu gostaria de ter lido mais sobre a história dele depois de ter vindo para SP e sobre o tempo no ITA, mas isso ficou para outro momento. De qualquer maneira, o livro é interessante se você tiver interesse em saber mais sobre a vida dele. Review of Why We Sleep: Unlocking the Power of Sleep and Dreams Unknown — Thu, 04 Jul 2019 00:00:00 +0000 Book: Why We Sleep: Unlocking the Power of Sleep and Dreams</a> by Matthew Walker. Rating: ⭐️⭐️⭐️⭐️⭐️. Amazing book! It has the potential to be life-changing for me. When I started reading it, my review was around 3 stars. This book is not easy to read and sometimes (especially in the beginning) it feels boring. It took me some time to engage in the topic. I think I felt the same when reading Deep Work. Now that I finished the book, I'm glad I was able to persevere reading it because there is a lot of good advice backed by science here. I still remember when during university years, I decided to study C++ (the programming language) from 0 am to 3 am every Wednesday (had to wake up at 8 am max). It was "the only time I had," and I wanted to go the extra mile to learn something new and exciting. After some months doing this, I realized it was not so productive, and until this day, I remember almost nothing of what I studied. I never gave that much importance to sleep and always tried to "optimize" the time awaken. After many years of experiments, I found that 7 hours of sleep was enough for me. I'm glad it was not less than that, or I would feel worse now. The best part of this book is the significant number of scientific studies referenced. It's not some article you read online that is interpreting some research in their way and telling you that you only need on average 6.7 hours of sleep a day. In this book, you will know dozens of scientific studies, their methods, and conclusions. These kinds of books written by scientists are fantastic (and sometimes boring... It can't be perfect) to help you draw your own conclusions based on serious researches available until now. I would totally recommend this book if you don't take sleep seriously and is interested in something that is free and can drastically improve your life. I did some sleep experiments in the past, but I will probably reboot all of them. My experiments start now! :) Here are my notes for this book: If you use the "I can sleep when I'm dead" there's a big chance you will be dead sooner than later</li> Sleep makes us very vulnerable to everything but evolution kept is in almost all animals all those years, so it has to be very important</li> Sleep is the single and most effective way to reset our brain and body every day</li> The Circadian Rhythm duration is more than one day</li> Night owls are usually penalized by society by having a different gene. It's not lack of effort that makes them not work well in the morning but their DNA.</li> 40% of the population are morning people, 30% are night owls, and the rest are in between</li> Melatonin helps to pace the sleep cycle</li> Because our Circadian Rhythm is bigger than 24 hours, it's easier to artificially stretch a day than shrink it</li> Jet lag happens when you travel through timezone but your circadian time is not adjusted yet</li> Caffeine is the only addictive drug we give to our children</li> Caffeine doesn't kill the urge to sleep; it just blocks the signals of the level of adenosine for your brain. When the caffeine effect passes, you will probably have a caffeine crash because of the level of adenosine accumulated</li> Wake state is learning, NREM state is reflecting, REM state is integration (integrating neurons with each other)</li> Your eyeballs show your sleep state. If you see someone sleeping and moving their eyeballs left to right, they are in a REM state</li> Imagine the possibilities if we (humans) could rest our brain one side at a time like dolphins and birds. One side remains awake while the other sleep.</li> REM sleep recalibrate the emotion circuits in the human brain</li> Alcohol for pregnant women or women who breastfeed is bad because it passes to the child and affects REM sleep. REM sleep is important to the formation of the child's brain and connection of neurons.</li> The same amount of alcohol present in the mother's blood will be passed to the children when breastfeeding.</li> Deep NREM sleep happens a lot during adolescence, which improves cognitive capacity and decision making</li> The brain is less malleable or plastic during adolescence. That's why kids can pick up a second language easier than adolescents. This explains why rationality is the last thing to appear in adolescents.</li> Deep NREM sleep is very important for adolescents</li> The circadian rhythm of children, adolescents, and adults are different. Children tend to sleep earlier, adolescents tend to sleep later, and adults kind of in the middle. Forcing an adolescent to sleep at 10 is like an adult going to sleep at 7</li> The lower is the sleep quality, the higher is the mortality risk according to research with adults</li> Sleep before you learn. There are studies showing that sleep helps your brain to retain more information. A nap at noon helps you to concentrate and store more information (20% more according to studies) while studying</li> We obtain most of our deep NREM sleep earlier in the night and most of our deep REM sleep and light NREM sleep later in the night</li> Early night sleep is the one who helps the most to retain fact-based memories</li> Sleep after learning is not a crucial way to store information, but it also helps to find memories you have but don't remember</li> A pianist said to the researcher that there are moments when we can't play a piece and go to bed, frustrated. The other day, he wakes up and just plays it. -- it's funny that it happened to me many times, playing instruments or even programming</li> It's not practice that makes perfect, but practice + sleep. After one night of good sleep, subjects show great improvement when compared to the ones who didn't sleep or got a bad night of sleep</li> During sleep, the brain fixes/automatizes motor problems you're having during the day. That's why the pianist doesn't have the same motor struggles from the previous day after a night of sleep</li> Sleep is also important for body recovery and improvement. It's especially true for sports.</li> Sixty years of academic studies don't let me trust people who say, "I'm fine with 4 hours of sleep every day."</li> After 16 hours awake the brain starts to fail. You need more than 7 hours of sleep to maintain cognitive performance. After 10 days sleeping only 7 hours a day, your brain is bad as if you were awake for one full day. 3 nights of sleep (more than a weekend BTW) are insufficient to recover after a week of short sleeping</li> Drowsy driving accidents are not really accidents because they have a cause and are predictable -- :(</li> Don't drive when you're sleep deprived. If you REALLY, have to do that. Take a 30min nap in a safe place. Wait for 20-30 min and then continue for a while. It will not last long but reduces the chance of an accident.</li> A researcher invites anyone who says he/she can live well with short sleep to go to his laboratory for a 10 days stay, so he can show categorically the brain malfunctioning. Until this day, no volunteer could hold their claim</li> Emotions are intensified when you're sleep deprived</li> People who sleep less have a greater chance of having Alzheimer</li> People who sleep less lose part of the "I'm satisfied" and gain more "I'm hungry" feeling</li> When sleep deprived we look for food with more calories</li> Freud described a dream as something coming from unconscious wishes that were not fulfilled -- is it why we say that we have "a dream" of becoming/doing something?</li> Freud analysis of dreams is unscientific but he knew a scientific explanation will come someday</li> Dreams are a by-product of REM sleep as heat is a by-product of a light bulb generating light</li> Dreaming is like a night therapy</li> It's not time per se which heal or wound, it's time dreaming</li> When you're sleep deprived, you can't read emotions property and the world looks more frightening</li> REM sleep is great for creativity. Many songs were composed during REM sleep (satisfaction, yesterday, etc.)</li> The periodic table was conceived after days of struggle and one night of good sleep</li> Lucid dreamers may be the next iteration of Homo sapiens by focusing their dreams and improving particular areas of the brain</li> What if Alien abductions are just post-sleep paralysis? The symptoms are similar and they are usually reported at night</li> If you know you are carrying a gene that will kill you by not being able to sleep, would it change your will to have children and spread the disease?</li> In a study, sleep-deprived rats (10+ days) started losing body mass even when they were eating well. When core temperature decreases, mammals increase the metabolic rate. Because of the lack of sleep, they could not control the body temperature and were burning from inside out (metabolic increase)</li> There's a study based on Hunter gathers that says humans only need 6.7 hours of sleep to live. When you look into the research, well-being, and life expectancy of the tribes researched, you get a different conclusion. (7-9 is still the recommended)</li> Sleep and time awake work together for a balanced life. It seems to be a good balance to have 16 hours of awake time and around 8 hours of sleep</li> We decide when it's night and when it's the day because of electricity and other artificial lights</li> Using an iPad (or any other LED device) to read before sleep reduces the creation of melatonin and directly influence the time and quality of sleep</li> Remove the blue light from your devices and use yellow lights at night to help to release melatonin.</li> Drinking alcohol at night also makes you feel exhausted the next day because of the lack of good sleep since alcohol affects your sleep in a bad way</li> A hot bath before bed helps sleeping better and have more deep sleep because your core will cool down right after</li> It's possible that sleep pills contribute to increased death risk. Such experiments will never be conducted because they are considered too risky by the ethics committee.</li> Sleep and wake up at the same time every day</li> Sleep and exercise help each other. When you exercise, you tend to sleep better. When you have a great sleep, you have better performance exercising</li> Low-calorie intake (800) contribute to bad sleep</li> Avoid going to bed too full or too hungry. Avoid heavy sugar food before going to sleep</li> Early school start time is bad for children learning and education. If the goal of educate our children, we are failing in the most spectacular way with the current early start time model.</li> Resident doctors don't sleep enough and takes them to eventually make possibly deadly mistakes.</li> We receive no education about the importance of sleep but receive some regarding sex, diet, and others (informal research)</li> Sleep appears to be a natural analgesic when done right.</li> </ul> 12 tips for a good sleep Stick to a sleep schedule every day.

It's a good book but maybe it's not for me. They mostly talk about their personal experiences and how they helped them to get better. There are some interesting experiences, especially because they were working for Google in the past and the culture of meetings is really strong there. I already knew many things exposed here, so it was not life-changing for me. I like to read again about the same topic because I'm still not applying some of the tips mentioned and it's a reminder that reading without applying is not very useful. The audiobook narration is also a little bit weird as they tried to do it together. I usually don't complain about the narration (sometimes I even use text to speech), but for some reason, this one was weird for me. To summarize, I would still recommend this book to someone who likes this style of writing and is just starting in the "deep work" side of things. Here are my raw notes about the book: As designers, our job is to turn abstract ideas like "it would be great if email sorted itself" into Gmail's priority inbox</li> Change the default from distracted to focused</li> Manage your energy and get work done more effectively</li> Choose one single highlight to prioritize every day and stay laser focused on it. During the day, build energy to stay focused on the goal and reflect about your day in the end</li> When choosing the highlight for your day, choose a task that takes from 60 to 90 minutes to complete</li> If you can't choose the next highlight, the previous one may still be important to keep</li> Think about what is most meaningful to you, not the most urgent when choosing your highlight</li> Block your time too, not just time for others (meetings)</li> You don't know if you could be a morning person if you don't try. It's OK not to be, but give it a shot.</li> If you want to wake up earlier, go to sleep earlier as well. Pay attention to the amount of sleep you need to feel good.</li> Lights and routine helps to get you up and ready for the day in the morning</li> Quit when you're done with the important work. Don't overwork or it will drain your energy for the important task the next day.</li> The average Brazilian watches 3.7 hours of TV every day — 💭 :(((</li> We evolved to like gossip and seek social status because it helps us to build a big network of contacts</li> My phone talk to me as the ring did to Bilbo Baggins. Any boredom and out of a sudden the phone is in my hand. — 💭 so true haha</li> Remove social media apps from your phone. You can always install them again if you really need them, don't worry about that</li> Turn off notifications of almost every app. A notification free phone is good for your focus</li> When you remove social media, the people who really want to get in touch with you and the people you really want to meet will find another way to contact you</li> "Contributing to a discussion on the Internet" is usually a fake win. Your brain thinks you did some work but it's worthless most of the time. Remember: your highlight is the real win</li> Office workers spend only around 30% of the time on real work, the rest is bureaucracy and organization</li> Don't respond to email right away. Unlike face to face conversation, you may have hundreds of people talking to you at the same time via email. Emails are their priority, not yours; prioritize it for you as well</li> Instead of signing in for TV (cable, Hulu, Netflix), sign in when you know there's something you want to watch</li> Stay without TV for a while and do other things. When this period ends, do you still want to have a TV?</li> Invent deadlines for yourself; it helps you to focus and deliver on time</li> Use a focus soundtrack as a cue (reference to [[book/The Power of Habit: Why We Do What We Do in Life and Business]]) to start your focused time</li> Try to workout every day. An exhausting workout may drain your energy for the rest of the day. Prefer something lighter but continuous. If you don't have time, consider high-intensity interval training and the 7 mins workout</li> Use caffeine wisely.

Rating: ⭐️⭐️⭐️⭐️. This book was in my reading list for a while. After an exam that requires pupil dilatation, I decided to go for the audiobook as it would not require any notes. :) It's interesting to see the influence of Norse Mythology in some things. I particularly noted that Ragnarok mentions the coldest winter, which is also mentioned in ASOIAF as something the is near to the end of the world. It was also nice to compare Marvel's Thor with the real Thor. They are totally different characters. After listening to this book, I now imagine Thor as a god version of Tormund (Game of Thrones), instead of the version we see in Avengers. Something unexpected is how much Loki participated in the whole story. He was part of all stories and also a crucial part of Ragnarok. If there's a central character, I would say it's Loki. The Norse Mythology also had their own Adan and Eve. This whole thing makes me wonder about the creation of religion and how everything relates to how their people see the world. The fact that the connection between Midgard (earth) and Asgard ("heaven") is a "rainbow" in a religion where people live in places where Auroras are common is an interesting correlation. :) The whole book is hilarious. I felt like someone listening to stories near to a bonfire. Many of these stories look very childish, which is very interesting. I would totally recommend reading this one. :) Review of Powerful: Building a Culture of Freedom and Responsibility Unknown — Wed, 29 May 2019 00:00:00 +0000 Book: Powerful: Building a Culture of Freedom and Responsibility</a> by Patty McCord. Rating: ⭐️⭐️⭐️. It's a good book but I was expecting more from it. I think it happened because I had the chance to attend a workshop with Patty and it was very good. My feeling is that the book was not bringing that much news for me. I part I like the most about this book is how Netflix "considers their employees as adults". Yes, I know it seems silly here, but c'mon so many companies don't do that. Companies and managers like to babysit their employees to a point that it looks ridiculous sometimes. One of the best advice here is to invest in your hiring process, hire people you trust, and let them do the work you need. Some advice is very hard to apply outside of Netflix (IMO) but it's still cool to know that it works for them. Here are my raw notes about the book: People have power, don't take it away from them. The "empowerment" only exists because we take power from the employees</li> The manager's job is to create great teams that do fantastic work on time.</li> Engineers have senseless bureaucracy but love discipline</li> Treat people like adults — 💭 I don't know why this is so hard for people. They want to hire adults but treat them as children...</li> The best you can do for employees is to hire high performers to work with them</li> Excellent colleagues, clear purpose, and highly understood deliverables. That's the powerful combination</li> We decided we are going to start treating people like adults and they loved it</li> The greatest achievements are achieved by a team that has enough freedom to apply creativity to solve problems</li> The biggest motivator is to have great people to work with you</li> It would be best if you operated with the leanest possible set of rules, approvals, and procedures</li> Eliminate as much as possible from processes and approvals; if you need them, you can always get them back</li> It's crucial that you people know how the business runs so they can make better decisions on their daily job</li> Why should investors know more about your company then people working on it?</li> If you don't provide useful information to your employees, they will find it somewhere else, and it's usually misguided information</li> If you're not honest with your employees about their performance and mistakes, you're doing them a disservice and being a lousy manager</li> If you want something from your employees, the standards must be set from the top-down, lead by example #Leadership</li> Preparing people for the changes to come, create a sense of honesty inside the company</li> Your people can handle the truth — 💭 They are adults after all.</li> Leaders should practice giving critical feedback, so it's cohesive and constructive</li> Fact-based arguments are not always true</li> Be aware of data masquerading the fact</li> We are limited by the team we have, not the team we should have. The people you have may not be the people you need for the future. Hire more experienced people for what you need.</li> Build the ideal team to get where you want instead of trying to adapt your team to what you want. Sometimes, a startup team may not be the best for a big company -- I'm not sure how much I would apply this...</li> The company is like a sports team, not a family. The team choice should be only based on performance for the job, and the team leader should always be looking for the perfect person for the job; it may be someone from inside or not. It's ok to let people go if they are not top performers</li> If you don't have enough expertise inside to do great things in a particular area, don't hesitate to look for it outside. If it's an area where you're driving innovation, you should already have the talent inside</li> Sometimes promoting is not the right solution</li> People should take charge of their growth (not offshore this to the company) to rise within the company or look for a better opportunity elsewhere #Career</li> Sometimes growing a company means that your team doesn't suit the company anymore and you need different kinds of people. It doesn't happen all the time (they may evolve to the team you need), but you have to let them go if it happens</li> Sometimes an employee may not be happy with the path the company is taking, but it doesn't mean that the path is wrong. Sometimes the employee is not ready/happy to work in a big company, and the company is naturally growing and wants to grow, so it's time for the employee to find another job</li> Learn to let go of people who have skills the company no longer needs, even if they are very talented employees and did great things in the past. Build the team of the future</li> True happiness at work doesn't come from perks; it comes from solving interesting problems with interesting people</li> "You are going to pay me much money for me to do what I love" -- it reminds me as a teenager. I would work for free just to have access to a working system</li> People who like music (play instruments) were usually good matches for the Netflix data team</li> Candidates are evaluating you as much as you are evaluating them — 💭 so true. Work is a relationship.</li> Consider paying top market salary to your employees so you can retain the best talents of the market. If you can't do it for everyone, do it for the key areas of your business</li> Be transparent about salaries; it doesn't have to be a top-secret topic. If you're afraid that it may cause problems, you're probably not able to justify the salaries you already have</li> Sometimes people are not a good match for the business. It's not about failure or anything like that. This person may be the most talented in their field, but it may not matter if you do not require this field anymore</li> Be transparent about how you can recommend employees when they are leaving the company. Sometimes you fire someone because they don't have good leadership skills but they may still be a good engineer, and you can recommend him/her for that</li> </ul> Review of Remote: Office Not Required Unknown — Thu, 23 May 2019 00:00:00 +0000 Book: Remote: Office Not Required</a> by David Heinemeier Hansson. Rating: ⭐️⭐️⭐️. The interesting part of reading this book is that I'm currently living most part of it in the past 2 years. :) The book itself is a little bit outdated as it was written in 2013 and we had a very different scenario then. They mention it in the first chapter, BTW. I found it to be a little repetitive as well, they are not very pragmatic about the content and decided to mention things over and over again so you can open the book in any particular chapter and use it as a reference (at least that's what I felt). Considering all of this, the book is not bad at all. I got some interesting thoughts about my current working environment after reading it. :) Here are my raw notes about the book: An office is a place nobody wants to go to get stuff done, it's a place of interruptions</li> If you can't trust your employees are working and not slacking, you're a baby sitter, not a manager</li> Learn to trust people you work with or find other people to work with</li> You're working remotely but it does not necessarily mean you're working from home. You can work from a coffee shop, library, or even a park. — 💭 LOL. Those people have no idea of how it works where I live</li> Most people WANT to work. If you don't have a fulfilling job, you don't need remote work, you need a new job</li> Security guidelines for employees: long passwords (password manager?), Encrypted filesystem, auto-lock, remote wipe for phone/tablet.</li> Have a single chat for people to discuss whatever they want as a team, just to shoot the breeze and post cat gifs</li> Progress is a Joy best shared with coworkers. Weekly work snippets are a good way of doing that</li> Instead of asking: what did you do today? You expect them to describe to their co-workers the work done</li> Meetings should be great but they're often overused and we usually don't find them productive. If meetings are the default way of discussing things, something is probably wrong</li> Social interaction is still important in remote work. You don't need to have social interaction with your coworkers only. Attend to nearby social interactions and choose different places to work</li> When you're working remotely, it doesn't matter if your coworkers are working from their home or a different country</li> Don't use remote work to pay smaller salaries, you can earn money with something else. Pay a big city salary to everyone and let them feel valuable. They will not find better deals where they live</li> Give real-world problems in interviews not just "puzzles"</li> When and where people are doing the work is irrelevant most of the time</li> Bring people together from time to time is important; it's a way to transform names into real-world people</li> Don't add roadblocks to your employees, give them space to try things, make mistakes, and improve. They should have access to all the data and systems necessary.s</li> When meetings are scarce you will value the time together — 💭 confirmed with Doist retreat, we really value the time we spend together once a year</li> Structure your day to work better. Split work and play so you can focus and relax. Clothes may help with that.</li> You don't have to be fully remote to enjoy the benefits of remote work. You can work in the office in the afternoon and use the morning to work from somewhere else</li> </ul> Review of The Joy of Less, A Minimalist Living Guide: How to Declutter, Organize, and Simplify Your Life Unknown — Mon, 20 May 2019 00:00:00 +0000 Book: The Joy of Less, A Minimalist Living Guide: How to Declutter, Organize, and Simplify Your Life</a> by Francine Jay. Rating: ⭐️⭐️⭐️⭐️. This is a book I can see myself writing. I would say that around 80% of the things said here regarding a personal organization I already practice since I was a child. The ones about decluttering I learned many years ago when my home was robbed and I decided to get rid of [almost] everything that was left. The book is a bit repetitive because the author decided to repeat every step for each space you're decluttering. I think it was done on purpose so you can follow the book step by step when doing it, but when you read chapter by chapter it is a little boring (especially in the audiobook). I would totally recommend this book to someone who wants to change the way he/she consumes things. I decided to do some decluttering (again) myself after finishing it. :) Here are my raw notes about the book: Minimalism is space. It doesn't have to be a white multi-millionary house with three pieces of furniture</li> Our stuff exists to serve us, not the other way around</li> Things you use (really use, at least weekly) can stay, not items of the "I will need someday" list</li> The things you have do not define who you are. Marketing tries to sell you that.</li> We are not what we own. We are what we think, what we do, what we love.</li> Having things is much work. Deciding to buy, looking for a place, searching for a deal, buying, bringing home, storing, taking care of it, cleaning, etc.</li> Not only items have value, but space also has too.</li> The person who knows he/she has enough is rich</li> Our happiness doesn't have much to do with the things we own after we reach a certain threshold</li> Separate your items into sell and donate. Some of them have no use for you but will make the day of someone else</li> When someone is around when you're doing the decluttering, it is sometimes easy to throw something away because you can't justify it reasonably</li> Don't use storage as an excuse to keep things you don't use</li> Decorative items are made to be on display. If you're storing them, why keep them in the first place?</li> All surfaces clean. If you're coming home with things in your hands, there's a big chance they will be put on the first clean surface you find. Keep them clean; surfaces are not for storage</li> Store your stuff in modules, so it's easy to find them. They will have an especial place to be</li> Do you like the craft of doing things or just collect material for them? Limit your storage and finish your projects</li> Once you discover the joy of limits, you will want to apply it to other areas of your life</li> Instead of thinking about getting rid of things the a, e.g., the shelf is full, people think about building a new shelf — 💭 LOL</li> Have Trash, treasure, and transfer piles/boxes. They will be used for trash, keep and donate/sell</li> Do you really need a TV? It's OK to have one but keep that in mind. Do you really need one?</li> Think about hobbies that don't need much material. Modules are especially good for storing hobby material. Avoid keeping them with other things.</li> Borrow things from friends or rent if you're not going to use it that much</li> Keep only two sheets for the bed. The warmer your environment is, the less you need</li> Remove everything from your wardrobe and start from scratch. Choose your style and plan a trip. Which clothes will you keep? What you would not use, think about donating/selling/trashing</li> Chose colors for your clothes that match each other. The goal is that you could look great dressing yourself in the dark</li> Don't keep too many similar items. Chose your best and declutter the rest</li> Limit your clothing to the available storage space. If there's no space to add more things to your drawer and all the things there are too good to get rid of, why are you buying new things?</li> Declutter your office: remove/archive paper not in use, clean surfaces, and add things to modules for easy access</li> You probably have many things in your kitchen that are used just a few times a year (fondue?). Would they really worth storing? You may go outside when you want it, or maybe borrow one from friends</li> Create a goal for decluttering and share it with your family members. Example: we're going to declutter the garage to be able to play music there with our friends.</li> Show you want to dedicate less time to stuff and more time to them</li> When we have the basics (clothes, shelter, and food) we don't have to consume; we should be careful about what we buy. Do we really need it?</li> Quality of life has nothing to do with the things you buy</li> We use consumer goods to show an image of ourselves</li> </ul> Review of The Coming Storm Unknown — Tue, 14 May 2019 00:00:00 +0000 Book: The Coming Storm</a> by Michael Lewis. Rating: ⭐️⭐️⭐️. A nice and informative book. It's not outstanding but I found it to have great information about how data can change the way we live, especially in this case where human lives may be in danger. The whole thing about the way the U.S. government deal with their data department is weird, but at least they have one. 🤷‍♂️ Here are my notes for this small book: Why the government has to invest in weather prediction if people are getting info from AccuWeather? Mostly because there are conflicts of interest in the private sector</li> The man chosen by Trump to have the government data doesn't have an issue with bending the truth</li> The government have to find a way to make the news feel real</li> We should not spread news without understanding people</li> People living in Mobile homes have 30x more chances to die in a hurricane</li> It seems to be all a matter of trust in the government warning for tornadoes</li> </ul> Review of Homo Deus: A History of Tomorrow Unknown — Sun, 12 May 2019 00:00:00 +0000 Book: Homo Deus: A History of Tomorrow</a> by Yuval Noah Harari. Rating: ⭐️⭐️⭐️⭐️⭐️. This is a great book that made me pause many times think. This is the kind of book I love to read. I heard some criticism about Yuval's books and they are mostly related to his way to connect things that he is not an expert about. For me, it's the best part of the books because it also makes me consider the connections and think about them. You don't have to assume everything as a truth when you read a book, especially when the books are mostly theoretical (as some of the "forecasting" shown on this one). It was really interesting to consider that we (Sapiens) may not be the center of evolution here on Earth. It's possible that we will cease to exist or evolve to something else that is not Sapiens. Think about it, and read the book to get the author's ideas on that. Here is my raw notes about the book: In the past, it was not that uncommon to die of hunger. Nowadays, we have more people dying from obesity than malnutrition</li> In times of plagues and infection diseases, people had no idea about bacteria. In their vision, it was some God that was spreading the diseases at night from village to village.</li> Currently, sugar is more dangerous than gunpowder. Diabetes is killing more people than violence.</li> Death is part of society. If people become amortal, things will start working badly (long-lived, politicians, bosses, dictators, etc.)</li> We are not here to serve the state; it is here to serve us</li> We become happy when reality matches our expectations</li> The evolution optimizes (prioritize quick pleasure) for race survival, not individual happiness</li> The more you crave pleasant sensations, the more unsatisfied you will become (because you can't fulfill all of them). Buddha says that you should understand and let the craving go so that you will be happier</li> The Best part of learning history is not to try to predict the future but to free yourself from the past</li> "For true humanist believers it may sound too pessimistic and depressing."</li> Humans are not considering the subjective needs of animals anymore, especially those raised in farms — 💭 :(</li> Animals also have their algorithms to survive. The quality control of these algorithms is natural selection. Bad algorithms lead to death and no offspring</li> A mother who doesn't care about children may live a long and comfortable life, but her genes will not be passed to future generations, which means that this behavior will be extinguished — 💭 OMG, that's an interesting way of seeing the current cult of parents.</li> According to Christianity, God gave an eternal soul only to humans (not animals)</li> In Christianity, God mediates the conversation between man and other things. In animistic faith, humans can talk freely to animals, clouds, and other things to avoid natural disasters, plagues, etc.</li> Emotions are biochemical algorithms</li> Rene Descartes said that Animals have no feelings or emotions. They react to pain just like a vending machine responds to the action of making coffee</li> Traffic jam is the term we use to describe the movement of many cars that causes something else.</li> Anger (or other feelings) is the term we use to describe the interconnecting of many neurons that generate something else. It's hard to know what creates a feeling looking to one particular change</li> Sapiens dominated earth not because we increased the size of our brain (it is actually smaller) or some physical characteristics, but because we can collaborate effectively and flexibly. Chimpanzees are not effective, and ants and bees are not flexible at all.</li> Rome conquered Greece not because they had larger brains or better tool making, but because they were able to collaborate effectively</li> Sapiens don't behave according to a cold mathematical logic; we act according to social logic. If someone is given money and has to split with someone else in whatever way this person wants, but the other part can accept or reject, they will not give just one dollar or nothing. If the other person refuses he loses everything.</li> Sapiens use visual signs as a turban, beard, or business suites to say: "You can trust me. I believe in the same stories as you."</li> We want to believe that our beliefs have objective meaning, i.e., they are not subjective at all</li> When a soldier went to the crusades, he envisions his death with light and angels taking him to the high heavens, as he was fighting for the cause. He would be astonished to know these are all stories created by humans.</li> The Gods didn't run their business because of the simple fact that they don't exist anywhere other than the humans' imagination. The business was run by priests just like Google and Microsoft have to hire flesh and blood humans to take care of theirs</li> Currently, we say that the United States built an Atomic bomb, so why not to say that Farell made a reservoir? Imaginary entities still have power on Earth through humans.</li> Schools started focusing on high marks instead of better education. It's one example of the reality adapting to something we invented for the worst</li> How to know if something is real? Ask yourself if it can suffer. When they burnt the temple of Zeus, he did not suffer. When the value of the Euro decreases, the Euro doesn't suffer. When a cattle is separated from her newborn, she suffers. When a soldier gets wounded in a war, he suffers.</li> Corporations, money, and Nations exist only in our imagination. Why would we sacrifice things to serve something that we created ourselves instead of our own interests?</li> Saying that God help us to help ourselves is just like saying that God doesn't exist</li> About religion: "We do not believe in superstitions, we believe in the truth. Only other people believe in superstitions" — 💭 LOL</li> Free market capitalism says that it's OK to lose family bonds in favor of economic growth. Example: a software engineer paying a low amount of money for a low-income and specialized person to take care of her disabled father.</li> The economy doesn't have to be a zero-sum game where your profit is my loss; it can be a win-win game.</li> Humanism is the opposite of religions like Christianism. Instead of God creating meaning to the world, humans are giving meaning to a meaningless world.</li> Socialists blame liberalists for focussing on their own feelings and needs and not thinking about others. The human experience is the source of all meaning, but there are billions of people out there with different needs</li> While liberalism focus on me and my feelings, socialism demands I stop obsessing about me and my feelings and focus on what others are feeling</li> In terms of progress, the war is not that bad. Many things exist because of war today.</li> "God is dead. It just takes time to get rid of the body" — 💭 LOL</li> The Catholic Church brought a lot of innovation in its time. Social organization, usage of libraries, usage of clocks, etc. What is the current innovation of the church compared to companies and scientists? The church is reactive nowadays</li> Liberalism believes that humans have free will, but we can be manipulated</li> It's possible to stimulate the brain to activate parts that make us want something. We can think that we choose something, but something enables the "want" for us. It's already being tested in lab rats</li> We are testing stimulating helmets in humans. It helps with concentration and focuses by stimulating the right areas of the brain</li> We're not individuals as we may have more than one "inner self". Our left and right brain can be disconnected</li> It's easy to believe in fantasy because it gives meaning to the suffering ("our boys did not die in vain" in the war)</li> We have the experiencing self and the narrator self. The narrator doesn't remember much and creates a story to fill the gaps. Usually, the result is an average of all feelings</li> People can choose the best locations for their vacation just to go there and waste time using their smartphones — 💭 LOL</li> Communism is a centralized data processing system, and capitalism is a decentralized one. Decentralized systems are more resilient to a big failure. Small failures can be easily corrected</li> Freedom of information will not be given to humans, but information. Humans may not be the center of this new interconnected information era</li> For some people, there's no meaning in not being part of the data flow. "What is the advantage of doing something if nobody is seeing" — 💭 LOLWAT</li> In the past, people were used to making jokes about Japanese traveling with big cameras and taking pictures of everything. Now, everyone does that. People don't "have time" to think about what they feel because they are too busy taking pictures, posting them, and waiting for likes</li> In the past, having power was having data. Today, having power is knowing what to ignore</li> </ul> How was Rust LATAM 2019 Unknown — Sun, 21 Apr 2019 14:02:54 -0300 For those who don't know, I'm a proud core organizer of the Rust LATAM conference</a>. 🎉 The conference happened on March 29 and 30, and this post describes how it was to organize the whole thing. Even with the small problems we had (as any other big conference), the feedback we received so far were very positive. We were able to bring amazing speakers to the conference, which brought high-level content even for beginners. Organizers</h2> </a> This post does not name people because I don't know how much they feel comfortable to be mentioned here, but there's someone that needs to be mentioned, and this person is Santiago Pastorino</a>. As the conference happened in Montevideo (Uruguay), Santiago was the main organizer and main contact to everything local to the place. He was the one doing the heavy lifting for most of the things related to this conference, and he has my full respect for that (and many other things). Don't get me wrong, we (other organizers) did some hard work too and I would mention others by name. We joined in different stages of the conference organization and committed ourselves in different levels, Santiago was the only one who started it and was there until we delivered it with the same level of commitment, that's why I decided only to mention him by name. I made some new friends while organizing this conference. It's great to see how you become friends with someone after you spend some days doing hard work and feeling the same pains and joys. At the end of the conference, I felt I knew these people for years already, and it was just 4-5 days working together. Of course, we had many interactions via internet, but it didn't happen to all of them, and it was less intense. I would say that the level of commitment to the same cause is proportional to the bonding of the friendship. Attendees</h2> We generated a chart about the demographics using the data from everyone who attended the conference. Here's the data we have for that: </a> Errata: After the conference someone noticed that Mexico was not included in the legend of the demographics chart when we presented in the opening speech, so I'm posting the right data now. It was my fault, sorry Mexico! The Rust LATAM community loves you! 🇲🇽 60%+ of the participants were Uruguayans. We were expecting that already since many of them were students. We did (Thanks Santiago!) some presentations at local universities to promote the conference and the language. We didn't have any problems with any of the attendees. Everyone behaved as expected for the standards of the Rust community and I hope many met some new friends to exchange information about Rust. Rust still has a small community in LATAM, but we're trying to make it better with this conference. :) Speakers</h2> </a> Here I'm also counting the workshop speakers not only the ones who were speaking on stage on Saturday. In the end, everything ran smoothly with the speakers. One speaker was not feeling well during the conference and we were worried about this person and also for the possible slot e would have to fill but the speaker was able to deliver the talk (which was great, BTW 😁). All speakers performed great (even when Apple Keynote decides not to cooperate 😜) thanks a lot to all of you that gave us your time and knowledge to make this conference happen. ❤️ Brazilians</h2> Yes, Brazilians deserve a topic. :) </a> For those who don't know yet (for some reason), I'm Brazilian. It's not so common for people in Brazil to go to different countries (I may be generalizing, but that's my feeling), mainly because Brazil is so huge. I was amazed to see we had more people from Brazil than people from Argentina there. 🎉 It's a common thing to have this "Brazil x Argentina" thing (because of soccer...), so I was joking about the number of participants. To be honest, I was happy to see that we were considering each other as fellow programmers of the Rust LATAM community and not people from country X or Y. We have a Rust Brasil</a> chat on Telegram that has 600+ members. There we have members from many different Brazilian states; it's a place to unite all the local meetups like Rust-SP (São Paulo), Rust-BH (Minas Gerais), etc. It was the first time we had a more significant meeting where people from different places could come to meet and talk to other Brazilian Rustaceans. We had an internal joke that it would be the first meeting of Rust Brasil...in Uruguay! What went well</h2> The whole conference went well. We feel that people are satisfied with what we were able to deliver. We collected some feedback and the general feeling was excellent. It seems we were able to do everything on budget as well, so we didn't have to spend our own [personal] money to deliver the conference and help speakers and organizers to get to Uruguay. This was only possible because we had amazing sponsors to help us with that. Thanks Rust LATAM sponsors!. We were able to deliver a pre-conference meetup, one day of workshops, and one day of talks. Considering the size of the team and how busy we were, it was almost a miracle (IMO). 🎉 The venue for the conference was great. We didn't have any problem at all with it. Thanks a lot to Antel for providing it. Problems we had and What has to improve</h2> Of course, there were many problems. The simple ones, the complicated ones, the funny ones, etc. We hope they were not apparent for the participants and speakers. :) Number of organizers and commitment</h3> We had fewer organizers than we wanted to have. Some of us were able to commit more than others, so we had to bring more people to the core group of organizers. Some of us had to leave the group in the middle of the process because they were too busy with other things; others were there but not able to do much. This whole situation made everything even more difficult. Next time we should probably get more people and more commitment in the beginning so it will be easier to afford losing people in the process without overwhelming everyone. Food and places</h3> We had some problems related to food and the usage of one of the workshops place. We paid for something and it was delivered in a different way than what was agreed. There was probably some miscommunication in the process, but it's hard to know how much of it was on purpose or just unprofessional. Intro to Rust Workshop</h3> The initial plan was not to have any wokshop, but we were considering having one done by us. In the end, we got awesome people to deliver workshops, and we could have spared ours. After some discussion, we thought it would be great to deliver our workshop still because there were many students enrolled and it would be a good thing for them. It proved to be accurate because it was the biggest workshop we had. The only problem is that it had to be delivered in Spanish and we had just two native Spanish speakers organizers attending the conference. Santiago became the responsible for the workshop. The problem of having Santiago doing the workshop is that he was already doing all the other things that needed someone from Uruguay and didn't have enough time to work on it. We slept less than we wanted and finished the whole slides and exercises together in the day before (which reminded us of our university times! LOL). We already had the content for the workshop, but now Santiago was "trapped into a room" for the whole day. Many things were only known by him (contracts, discussions by phone, etc.) because he was the one dealing with locals. Well, in the end, he became the single point of failure of the conference. We managed to fix everything by covering him during the workshop exercises but it was not an easy task to do. It was great to have an Intro to Rust workshop, but we did not plan it in the right way. Next time we will probably have someone other than the main organizer doing that! LOL. Backstage stories</h2> Well, we have some interesting stories from backstage to tell you. 😁 Having fun with the language mess</h3> It was hilarious to have Italian, English, Spanish, and Portuguese all mixed up between the organizers and locals. We used English as the lingua-franca between us (where's Esperanto? :P) but we also had to deal with locals that only speak Spanish (venue, catering, etc.), so we had to switch languages from time to time. I remember when one of us was speaking Italian to the Spanish speaker organizer by mistake. His face was: "Why is he not understanding me?". Very funny. There was also one time when we were discussing the workshop (2 AM) and the Spanish speaker read something in Spanish in an e-mail and after that, this person made the switch to Spanish while we were looking to him/her laughing and trying to understand what he was talking about. I have to say that I had a lot of fun with these situations :) Lost backpack</h3> We were using a rideshare app to go from one place to another. We had to bring boxes of t-shirts, bags, banners, and other things to the place we were staying. You can imagine that the logistics were not easy. In one of these rides, one of us took the boxes but forgot to get the backpack from the car before leaving. We tried to contact the driver, but it's not that easy to do that using this app in Uruguay. When we finally could get an answer for the driver, he said that there was no backpack there... That's nothing to do about it other than report it to the police. Well, it was awful for the organizer (and for the whole conference organization), but it became even worse when we found that this person's passport was also in the backpack. We started the process of getting a new passport during the workshops day so him/her would be able to get home in time. It's a long and stressful process. Trapped organizer</h3> One of us was out to bring the tablecloths for the sponsors' table. When this person got to the place, it was almost closing, and he/she got trapped into the garage. One of us had to go there to release him/her but this person was able to release [him/her]self before we arrive. :P Conclusion</h2> Organizing an international conference is tough. It took a lot of my time in the past 3-4 months. There are so many details to consider, and sometimes basic things you consider as done comes back to bite you. The feeling of accomplishing something that big with positive feedback is something that you take for life. I'm very proud of being part of the team that made it happen. Well... The best way to end this post is to thank everyone (attendees, sponsors, speakers, organizers, etc.) who were there to make it happen. 🦀 </a> Cascais Unknown — Sat, 13 Apr 2019 00:00:00 +0000 A friend of mine was driving us to nice places around Lisbon and he recommended us to go to Cascais, which is a place he likes. Transport</h2> We went there by car with a friend, so not much to say about other ways of transport. Places</h2> Centro histórico: Just walking around the historic center is great. If you have some time, go do it.</li> Forte Nossa Senhora da Luz de Cascais: Small fortress, not expensive to get it. I enjoyed the visit.</li> Boca do inferno: A famous place where you can see the waves smashing into the rocks and the cave. I really liked the visit. The whole place is quite relaxing.</li> </ul> Food</h2> Restaurante O batel: This was the place we chose to have lunch during the car trip and I have nothing to complain about it. I'm writing this 4 years after the visit, os I can't really say what I had at the time, I just remember it was good it not very expensive.</li> </ul> Colares Unknown — Sat, 13 Apr 2019 00:00:00 +0000 A friend of mine was driving us to nice places around Lisbon and we went to Colares just to see one single place: Cabo da Roca. Transport</h2> We went there by car with a friend, so not much to say about other ways of transport. Not sure if it would be easy to visit using trains. Places</h2> Cabo da roca: The view from the mountains and the see is astonishing, it was a great place to visit. We spent some time chating and appreciating the views.</li> </ul> Lisbon Unknown — Wed, 10 Apr 2019 00:00:00 +0000 I had the chance to visit Lisbon two times, both of them visiting friends and staying with them. Stay</h2> I have friends living there and they kindly offered a spare room in their appartment for us to stay while traveling. It was amazing to have the day to explore the city and spend the night with them playing cards, having some good wine, or even having dinner somewhere. The other time I went, there was another friend of mine hosting me for a long layover, so I would not have to sleep at the airport or look for a place for one night. After finding these people, I realize that travel is becoming much less about places and umch more about people we like. :) Airport</h2> The airport is good enough, nothing to complain. There's a train that you can use to go from the airport to the main city Transport</h2> The subway and trains work great to go anywhere we wanted to go. If Places</h2> Parque das nações: A redeveloped area which became a large modern park. A friend of mine was walking us around the place. I was quite different than what I was expecting, and I enjoyed it.</li> </ul> Food</h2> TBD</li> </ul> Porto Unknown — Sun, 07 Apr 2019 00:00:00 +0000 I've been in Porto for the first time in 2017 when I first joined Doist</a>, but also had the chance to visit the city in 2019 in the company retreat. I really like the city. Unlike Lisbon, it feels like a city that is not so big but is also not so small. To me, it feels right in the middle of a big and small city, with historical places and nice views. Torre dos clérigos</h2> I enjoyed my visit there. The view from the top is nice, and the whole place is very historic. Wine tours</h2> I didn't do any, but I visited a place to have a few different wines. If you like (or never tasted!) Porto wine, I totally recommend it. Francesinha</h2> It's a traditional dish of the place, I really recommend you to try one. Walking tour</h2> There are many walking tours starting from the main square. I'm a big fan of walking tours and this was no exception. Azores Unknown — Mon, 01 Apr 2019 00:00:00 +0000 I went to Azores (actually, Açores in Portuguese) in the Doist company retreat of 2019. It was a hell of a ride to get there because there was a lot of complication to leave Uruguay (I was organizing Rust LATAM</a>) and get there. Maybe it's a story for a different context. Anana</h2> We visited a place where they cultivate a specific local Anana. It looks like a pineapple, but it has its own category. Bus tour</h2> We did a bus tour through the island and got some amazing views Montevideo Unknown — Tue, 26 Mar 2019 00:00:00 +0000 In March 2019 happened the Rust LATAM 2019</a>, which I was one of the main organizers. It happened in Montevideo, so I had some time to also walk around the city and get to know a few places. My plan was to visit a few more places, but the Doist retreat would happen the day after the conference and I wouldn't have enough time to do anything before. would recommend people to stop there, see the train station and move on. Stay</h2> I stayed in a hotel for 1 or 2 days when I arrived and then all organized went to the same Airbnb so we could reduce costs. Transport</h2> I got the bus to come from the airport to the city downtowm. As I usually travel with one bag, it was quite simple. Other than that, I mostly used Uber when the distance was not walkable to move around because it was easier. Walking was mostly OK for the places I wanted to visit. Places</h2> The train station is quite nice. It's the place I spent some time, just looking around.</li> </ul> Food</h2> Nothing that I remember and it's worth listing. Just cheap food and nice fries. :)</li> </ul> NYC Unknown — Mon, 25 Mar 2019 00:00:00 +0000 I had to chance to go to travel to NYC more than once. The first time I came there alone and the second one I went with my wife and both trips were good. Airport</h2> I always try to go to JFK because it's the biggest and simplest airport to use. The airport is really big and they have a train called Airtrain, that can be used to go from one terminal to another and also connects to the Subway. Transportation</h2> The transportation in New York is amazingly practical (but dirty). I was able to use the subway to go anywhere I wanted. There are stations almost everywhere. I would recommend you to buy a weekly pass for the Subway so you don't have to keep track of your credit. Believe me, if you're planning to visit many touristic places, it will worth your money (yes, I do the math every time before buying something). It costs around $30 (as of mid-2019) and if you consider 1 round trip from e.g. Brooklyn and one trip here and there it would be worthwhile. Be careful with the side you're going to enter in the subway. Where I live (São Paulo, Brazil) you can enter on whatever entrance and then pick the side you want (e.g. North or South). In NYC you have to be sure you're entering in the right entrance because some stations have one entrance for each side (e.g. one entrance to go to Manhattan & the Bronx, and another one to go to Downtown Brooklyn). Places to visit</h2> There are some places that are must see (IMO) and others that are nice but OK. Here are the must see and why: Statue of Liberty: I almost not went there for the first time because it seemed too crowded and was 'just a statue'. In the end I decided to go and the whole experience proved me wrong. It's not just a statue, the whole story behind it is really nice to know. It worth the money you pay to go there. The entrance to the pedestal is still a puzzle for me. I got it the second time I went but not the first, I don't know why. I would recommend you to ask for it or do some research before. If you want to go to the crown of the statue, you have to reserve it beforehand.</li> Transit museum: I really like steam engines and the whole history about trains. The transit museum has a lot to tell about the NYC subway. It was really nice to understand why the subway work that way.</li> Natural history museum: The first time I went there, I was one of the first visitors to enter and left when the museum was closing. It's a big place with so many amazing things to see. I would recommend going there early and going straight to the dinosaurs room because it's the most crowded. After that you can enjoy the museum on your own pace.</li> Morgan Library: I may be a bit biased because I went there for a exposition about J.R.R Tolkien. I went on a Friday night and they had free entrance.</li> Brooklyn Bridge: I went there once and was surprised by how beautiful it is. I went walking from one side to the other and it was a fun experience.</li> New York Public Library: It's worth a visit, the place is quite nice and there's even a place to work if you need a desk and internet.</li> Rockefeller Center: There's a huge building there and you can go to the top. It was a great experience because you can see the whole city and the empire state and Chrysler buildings.</li> Empire State Building: It's a nice place to see the whole city, but I would recommend going to the Rockefeller tower instead. The view is mostly the same, but you can see the Empire state from there.</li> Intrepid: It's a museum about the US Navy and it's really nice. It's not that big, but it's worth a visit.</li> </ul> And here are some that were good but I'm not sure if I would go again: Ellis Island: OK-ish, but maybe I was too tired from the trip to the statue.</li> Brooklyn Museum: It was different and the place is nice, but not many expositions that would grab my interest at the timei</li> Times square: too crowded and nothing really interesting to me, to be honest.</li> </ul> New York city pass?</h3> It's not my kind of travel (I didn't buy it) but does it worth the money? Maybe. I usually choose the places I want to visit first and then I look into the prices. People who buy the New York city pass tend (trying to avoid generalizations, it's according to my sample size) to do the opposite. They look into the city pass, read about the attractions there and go visit them. The transit museum, that is in my "must see" list is not part of the city pass. The Natural History museum is pay what you want, so you may not consider the full price (but at least $10 is worth sparing, it's a great museum). Places to eat</h2> (if you really care about food, skip this part because I don't. This list is for those who just like me wants a list of places to not have to care about looking for places to eat). I went mostly to quick lunches, so you will see fast foods most of the time here. I usually don't eat at big and known places like McDonald's, Burger King, etc. but I look for places where I can quickly eat something and go to the next location. Shakeshack: There are many of them and the burger is good enough</li> </ul> Review of Atomic Habits: An Easy & Proven Way to Build Good Habits & Break Bad Ones Unknown — Fri, 08 Feb 2019 00:00:00 +0000 This is an amazing book! I've been reading about productivity and habits for a while now and I think this book does a great work of gathering everything together and presenting it in a nice form. I think I liked it even more because I already apply many of the tips written here and I can assure (at least to myself) that it actually works. I have to say that it was really great to hear confirmation of what I've been doing for years. :) If you already read the Power of Habit, you will see some references in this book but it will add other tips that you didn't see there. I also found this book to be less dense. Here is my raw notes about the book: The aggregation of marginal improvements. If you break all actions and improve them separately, you will have again when you put all of them together</li> You will only notice the value of good habits and the price of the bad ones 5 or 10 years from now</li> Small improvements may not be seen at the moment but they compound with time</li> Habits compound with time as you repeat them</li> Small change in the path may be very meaningful in the destination</li> You should be more concerned about your current trajectory than your current results</li> If you're a millionaire and you spend more than you earn, you're on a bad trajectory. If you're broke but save some money every month, you're on the trajectory of financial freedom, even if it's slower than you expected</li> One big change is not the result of one single action but the aggregation of many others. You should not give up because you're not seeing changes in the first stages, sometimes it takes a long time for you to shape what you want</li> Fix the input and the output will take care of itself — 💭 it's the same idea of The Score Takes Care of Itself: My Philosophy of Leadership</a></li> When you meet your goal, there is a chance that you will not keep yourself motivated to keep your system running. e.g. a racer will not keep training after the race is gone</li> Atomic Habits are little habit that is part of a larger system</li> If you want better results, forget about setting goals, focus on your system instead</li> Sew things give you better results than changing your daily Habits</li> Changing outcomes is the first layer of habits (most of the goals you set). The second layer is changing your process (improving your system, like preparing a better workout for the gym). The third level is about identity (change what you believe)</li> We should focus our change on identity habits and think about who we want to be</li> A behavior that is incongruent with the self will not last. You have to assume you're the person you want to be and become it.</li> The ultimate form of intrinsic motivation is when something becomes part of your identity. When you say "I'm this", you reached this goal.</li> The goal should not be to read a book but to become a reader. It should not be to run a race, but to become a racer</li> When your behavior is aligned with your identity, you don't have to force yourself to do things, you are just being yourself #Habits</li> Be careful with the "that's not who I am" mentality. If you repeat to yourself that "you're not good with names" many times, you will accept that as truth and will not improve</li> Habits are how you embody your identity. Your identity is your "repeat beingness" (translating from Latin)</li> First, decide the type of person you want to be, and second prove it to yourself with small wins</li> You can start with your goals (have six-packs) but then think about WHO is the type of person that can get there (gym enthusiasts?)</li> Whenever you face a problem repeatedly, your brain starts automating it to get the reward with less effort</li> The goal of a habit is to solve life's problem with as little effort and energy as possible</li> Most people think they lack motivation but they lack clarity of when and where to execute what they want</li> Fill the following sentence: I will [behavior] at [time] in [location] #Habits</li> Stack habits: you can use the habit as the cue for another one. e.g., after coffee, I will meditate</li> Habits scoreboard: list all your daily habits (wake up, look into the cellphone, brush the teeth, take breakfast, etc.) and add a minus sign to the ones you think are not good for you, a plus sign to the good ones, and an equal sign to the neutral ones</li> Use something like your scoreboard to list everything that you do each day without fail (wake up, brew a cup of coffee, take kids to school, etc.) then list everything that happens to you every day (sunrise, lunch, sunset, a song you're listening to ends, etc.). With that list, you will be able to find the best time and place to stack your habits</li> Make your cues obvious in your environment. If you want to eat apples, keep them in sight so you will not forget them</li> We usually connect the place with the habit. You can train yourself to link a particular habit with a particular context</li> Associate places with activities. e.g., an office for work. The couch to rest and have fun, etc.</li> "I've never seen someone sticking to positive habits in a negative environment".</li> Reduce exposure to the cues causing bad Habits. Move the television out of the bedroom. Move your cellphone out of the office. Etc.</li> Make the cues for bad Habits invisible</li> "Make attractive". The whole market uses it in their favor. Fashion with pictures of models really modified, food over caloric to trigger the brain, porn that is not something you can usually do, social media gives much more likes than you would receive in a real environment, etc.</li> "We have the brains of our ancestors but temptations they didn't have to face."</li> Without the desire the action stops (experiment with "dopamine free" rats)</li> Temptation bundling is when you tie something you want to do with something you need to do (pedaling to watch Netflix)</li> The more attractive something is, the easier it is to build a habit</li> Try to pair an action you want to do with an action you need to do</li> Behaviors are attractive when they help us to fit in a group</li> Our friends and family provide some sort of peer pressure that pulls us in their direction. Peer pressure is only bad when you're surrounded by bad people</li> The higher the IQ of your friends at the age of 12, the higher will be your at the age of 20+</li> The best thing to do to have better Habits is to join q culture where the desired behavior is the norm</li> Surround yourself with people who have the Habits you want to have. You culture set your expectation for what is normal. You will rise together.</li> There's a tremendous internal pressure to adhere to the norms of the group. The reward of being accepted is often higher than looking smart or winning an argument</li> We usually go with the flow, even when the group is wrong. You can be different and don't care about what people think, but it takes work</li> When the change goes with the tribe, the change is attractive. When it goes against the tribe, it's unattractive — 💭 I'm not sure if it's always true for me</li> Once we fit in, we find a way to stand out of the crowd</li> We imitate the people we envy (because they already stand out the crowd)</li> We try to imitate three different groups: the close (family), the many (groups), the powerful</li> Some underlying motives: conserve energy, obtain food and water, find love and reproduce, connect and find bonds with others, win social acceptance and approval, reduce uncertainty, achieve status and prestige, etc.</li> The successful products today are not creating new motivations, they are just bonding themselves to the underlying motives of humanity. Examples: find love (tinder), reduce uncertainty (Google), connect with others (Facebook), look for approval (Instagram), etc</li> A craving is a sense that something is missing, is the desire to change your internal state. When you do something (e.g., browsing social media) you're looking for the feeling of change in your internal state (feel accepted? Feel part of the group? Escape? )</li> When Habits addresses a motive, you will feel the craving to do it again</li> Habits are attractive when you associate them with good feelings. You can use that to your advantage</li> You can reprogram your brain to associate hard habits with positive experiences — 💭 fck, I do that all the time. Just realized it now 😱</li> Motivation ritual example: if you play the same songs to have sex, you will begin to associate the music with the act. After some time, you can just play it to get in the mood.</li> Find something you love to do and create a ritual for that. You can then use this same ritual to get some boost of happiness.</li> If you can reprogram your predictions, you can transform a hard habit into an easy one</li> Motion and action are two different things. Motion is brainstorming a book. The action is writing that book. In motion, it looks like you're making progress, but you're not doing much. Be careful with that.</li> Particular regions of the brain get bigger when they are used and reduced when not used, just like muscles</li> When you do more of something you learn from your mistakes, train your brain, and get better. Don't theorize much, plan and act.</li> It doesn't matter how much time it takes to form new Habits, but how many times you have to do it to become a habit.</li> We tend to do things that don't require much effort. If you can make your habits more convenient, you have a better chance to stick to them.</li> Environment building: prepare your environment, so it benefits you to accomplish your habits. For example: if the gym is between you and your work, it will be easy to plan for it</li> Prime your environment. Whenever you finish something, prepare the environment for the next use so there's no friction to do it again and it will always be tidy and clean</li> Use friction to avoid bad habits. Example: remove the battery from the remote control to avoid watching television. If the friction is high enough you will forget it</li> Habits are the entry point, not the endpoint. They are what guide you to the gym, not the exercise</li> To start a new habit, start with something that only takes two minutes (scale down if it takes more, so it takes only two)</li> Positive experiences cultivate habits, negative ones destroy them</li> Use immediate rewards to help with delayed gratification. To save money for the future, you can stop eating out. Every day you eat out, get the money you spare, and move to a savings account. You will have the immediate reward of savings.</li> The more a habit becomes part of your identity, the less you will need reinforcement. The identity becomes the reinforcement</li> Don't focus on having six-packs, but instead focus on being the person who exercises the abs X times a week</li> Never fail twice. If you don't, e.g., go to the gym one day, go there in the next one</li> Sometimes we just improve what we are measuring, but we may be measuring the wrong thing</li> Make bad Habits unsatisfying. If you break your chain of good habits (creating a bad habit) make it unsatisfying by punishing yourself in a way you think fits the situation. It should be unsatisfying.</li> Genes do not determine your destiny, but they determine the chance of you to excel in a particular area (Phelps has a good body for swimming, but not for running)</li> Choose the habits that interest you, not the most popular</li> Pick the games where the odds are on your side. You get more satisfaction when things are going well and easy for you.</li> Combine your abilities to create your own niche. The guy behind Dilbert is not the best cartoonist and doesn't have the best jokes, but the combination of both of his skills is awesome</li> Build your own category of study/work, the one that combines your skills and makes yourself to be the best candidate</li> Who can handle the boredom of doing the same things over and over usually are the ones who become masters</li> You need just enough winning to experience satisfaction</li> When habits become routine, they become less challenging and less satisfiable</li> Don't make any single part of your identity a big portion of who you are. If you lose (or have to change) this part, you will have an existential crisis and lose a big part of your identity</li> </ul> Review of 21 Lessons for the 21st Century Unknown — Tue, 29 Jan 2019 00:00:00 +0000 Book: 21 Lessons for the 21st Century</a> by Yuval Noah Harari. Rating: ⭐️⭐️⭐️⭐️. I just read Sapiens and I don't think this book is so good as Sapiens is, that's why I decided to go with 4 stars. I like the way Yuval brings some topics to the discussion. This book made me think about many things I usually don't think about. Religion is a topic I like to read/listen to from different angles, for example. Here is my raw notes about the book: The internet was a big change in society, and it was created by engineers. Have you voted for the internet? I don't think so, and it's here.</li> Perhaps in the 21st century, the revolt will not be with an economic elite that exploits people, but with an economic elite that doesn't need them</li> People connect with Art because they find themselves in it</li> A Basic income program may actually work when we start losing our jobs to AI</li> Referendums don't ask about what people think but what they feel</li> With enough data, an authoritarian regime may know you better than yourself and make you love them and hate their enemies</li> Instead of collective discrimination by race or gender, we may find individual discrimination by algorithm analysis of our profile</li> Conscious is related in some way to organic systems, and it would be impossible to recreate it in non-organic ones</li> Algorithms and data may distribute wealth in an unequal manner. In the future, poor people may not suffer from exploitation but from irrelevance</li> If treatments to extend life prove to be expensive, humanity may split into biological casts, where the rich live longer — 💭 altered carbon?</li> Nationalism, religion, and corporates divide humans into hostile camps and make it hard to cooperate at a global level</li> "It's easy to talk to my cousin in Switzerland (through the internet), but it's hard to talk to my husband during breakfast because is constantly looking at his cellphone</li> If you don't feel at home in your body, you will not feel at home in the world. We've been losing the connection with our body and sensations in modern times.</li> Facebook tries to create tools to help people share their experiences with others, but what people might need is tools to connect to their own experiences. Currently, people share everything and wait for "likes". What other people feel is part of people's experience</li> The economy is everywhere. When the Islamic State takes a city, they destroy all Western cultural reference and religion, but they still use American dollars that contain American presidents and gods stamped on it</li> To solve global problems, we have to start thinking globally. Better global politics is necessary</li> Priests and scientists are good at coming up with arguments when things don't go as well as expected, but scientists improve their craft (remedies, etc.) while priests get better excuses</li> If you are a tourist in a country and you know nothing about history, you still have to deal with the consequences of that history</li> Terrorists have no army, they inflict damage by doing a show and tricking the other side to overreact and try to protect every citizen in every place all the time</li> Sigmund Freud's mother was really important for his growth, but we don't study her. The same happens for Judaism and Christianism. Judaism influenced Christianism, but we don't have to say study Judaism just because of that</li> That's something wrong in people that avoid killing just because God said so. We should avoid killing because we don't want to inflict pain on others</li> Seculars are in favor of things that do not inflict suffering to people</li> What made homo sapiens so successful is our ability to think together as large groups</li> It's hard to blame people for all the atrocities happening (animals with a poor life on farms, child labor in other places, etc.) just because someone lives a certain way of life. The network of political and economic things is too big to draw conclusions.</li> How can we act morally if we don't know all the facts? (e.g. investing in a company who pollutes a river and hire tens of lawyers to protect them)</li> When thousands of people believe in a false story for one month, we call it fake news. When millions of people believe in an unproven story for thousands of years, we call it a religion. We should not call it fake news to not hurt the feelings of faithful</li> A lie told once is just a lie. A lie told 1000 times to become the truth — 💭 marketing (Coca-Cola?), Religion?</li> When people see a dollar, they don't feel weird just because it's a human invention, they just trust it</li> To watch or play a soccer game, you have to accept the rules of the game and suspend your disbelief. If you don't do that, the whole scene of 22 people running after a ball becomes really silly</li> Soccer can formulate human identities or even create violence, just like religion. Humans usually don't think about focus, if we focus, we will see that many things are just fiction and exists just because we believe in it</li> Power and truth go ie different directions. If you want power, you have to start spreading fiction. If you want the truth, you have to forget the power</li> Do you control the technology or does the technology controls you? Are you one of those zombies walking through the streets looking into their smartphones?</li> If you want to just go with the flow, don't worry, the algorithms will take care of you. If you want to be in control, you better run fast than the algorithms and know yourself better than them. To do that, don't take much baggage with you, they are too heavy for this journey</li> The Bhagavad Gita talks about a warrior in doubt about his path. Krishna says that everyone has a role to fulfill in life and you will only feel joy when you find your role. The warrior then becomes kills their parents and relatives, leads his army to victory, and becomes the greatest warrior. "The Lion King" movie seems to tell a similar story about the circle of life and how Simba has to fulfill his role in it, but Mufasa plays the role of Krishna in this one. Simba wandered around using the Hakuna Matata mantra and not fulfilling his role, which brought a lot of doubt to him</li> People in Israel have to take care of the "eternal land" but this concept of "eternal land" is absurd when you consider the time of the universe, the whole history, and what physics tell us about the future</li> "hoc est corpus" (this is the body) in Latin may have become "hocus pocus" in the ears of the peasants who don't speak Latin. It became the word when someone wants to transform something into something else. — 💭 😱</li> More sacrifice brings more believing. This is one of the reasons women were asking their future husbands for extensive rings. If it was worth expending that much money, it was something worth investing</li> Public transportation is banned during Saturdays in Israel because of the Sabbath. This is a big deal for the working class who don't have cars because they can't visit relatives or tourist attractions. The same doesn't happen for the rich. It is a sacrifice for the religion.</li> Fascism word is being misused nowadays. People call everyone they don't like a fascist.</li> Our inner narrator usually gets things wrong usually doesn't admit it. It usually creates a personal myth with good memories that little resembles the truth. In social networks, you can observe it clearly because part of it was transferred to the computer. People spend a lot of time creating their perfect online version and becoming attached to it. That's how a simple family trip with lots of traffic and tense silence becomes pictures of smiles and a nice landscape. 99% of what we experience never become part of the self</li> Our fantasy self is very visual, and our real self is sensorial. When you imagine/see a nice place you can't feel what that moment brought. A picture smiling on the beach may also have sun burning the skin, mosquitos, bad food in the stomach, relationship problems, etc.</li> Now, with television, it became easy to delude people.

Hunter. Rating: ⭐️⭐️⭐️⭐️. This book was a big hit in Brazil for a while and of course, I heard about it in the past. I'm a bit skeptical about books that became a hit, so I didn't pick this one. My sister asked me to buy this book for her as a gift and I decided to buy one for me too so we could discuss it. This book chooses to give some good advice by having some fiction narrative. Now I can see why it was popular here. It's a lightweight book with some great advice about leadership. It's not a good narrative though, it's just good enough to pass the message. I would prefer a non-fiction book, but it doesn't mean the book is bad. It's not the first time I see some of the leadership advice given here, many of them are also part of the 21 irrefutable laws of leadership. If you're looking for light reading with some good advice, I would recommend this book. If you're looking for something deeper, there are better books out there. Here are my raw notes about the book: Leadership is about the influence</li> You can be a good Manager and an awful leader. You can also be a good leader and an awful manager.</li> Great leaders have humility (focus on their people, not on themselves). They also have a strong and professional will to do the right thing.</li> Leadership, character, and love are synonyms</li> Can you imagine following a leader who it impatient, unkind, arrogant, etc.?</li> Leadership is not something you can learn without practicing</li> Leadership and character are one. The character is that person you are when you're alone</li> Be the change you want to see in the world</li> Power and authority are two different things. Power is something you use to command: "take out the garbage or...", "Do this, or you're fired", etc. Authority is when people do things because they believe you're doing the right thing and they want to contribute to that</li> Trust is the glue that keeps relationships together. How many people you don't trust and still have a good relationship with?</li> When you cut people in the middle of the sentence you're passing a message the what you have to say is more important than what they have to say. If you truly respect them, you have to align your feelings with your actions</li> We don't see the world as it is we see the world as we are</li> The reasonable man adapts to the world. The unreasonable man tries to adapt the world to himself. Because of that, most of the progress comes from unreasonable men.</li> Seagull Manager come sometimes, make a lot of noise, dumps some shit, and fly away.</li> The top of the hierarchy pyramid has to serve, not be served. Employees have to serve the client.</li> When you start seeking the good in people, you will start seeing it more and more. Just like when you start looking, e.g. a new car, and suddenly you can see many of them in the streets</li> When people are late, they are sending a message that their time is more important than my time. It also passes the message that they are not very honest because they are not committing to their word</li> Everyone wants to be involved, but nobody wants to be committed</li> For each time you mistreat someone, you have to praise at least four times to get to the same level</li> Everybody wants to change the world, but nobody wants to change themselves</li> Some people are predisposed to be drunk because of their parents, but it's up to them to drink the first cup</li> If we don't stand for something we will fall for anything</li> People first buy to the leader and then to the vision</li> Do you judge the quality of a family picture by how YOU look? This is a self-centered signal — 💭 That's interesting. It's not something I do, usually.</li> </ul> Review of The 21 Irrefutable Laws of Leadership: Follow Them and People Will Follow You Unknown — Thu, 20 Dec 2018 00:00:00 +0000 Book: The 21 Irrefutable Laws of Leadership: Follow Them and People Will Follow You</a> by John C. Maxwell. Rating: ⭐️⭐️⭐️. I was between 3 and 4 stars and decided to go with 3 for this one. It's a good book, I don't have much to complain about it. Some "laws" seem to be fillers to me, but many make total sense. I would recommend it to someone, but reading a summary first would probably give you 80% of the value the book can bring. The other 20% will be stories and examples there. Instead of writing a big summary, I would recommend you look for one online. Just found this one</a> that seems to be about right. Here is my raw notes about the book: Without Leadership, a person's impact is just a fraction of what it could be</li> If a company is in a bad situation and someone is hired to improve the situation, they always fire the leaders because they were not good leaders after all</li> Not all entrepreneur are leaders</li> Leadership is influence, nothing more, nothing less</li> Leadership and Management are two different things. Leadership is about making other people follow you and management is about following processes</li> Knowledge is power, but the most knowledgeable person is not necessarily a leader</li> If someone thinks he leads but he has no followers, he is just taking a walk</li> To be an excellent leader, you have to work on your leadership skills every day (Larry bird did 500 free throws every day before going to school)</li> As a leader, you have to help your team to navigate to the correct destination in the best way possible. You have to have a plan for the journey and each individual.</li> To be a leader you have to add to others, not subtract. If you're a leader, you ARE adding something or subtracting something from your followers. Are you making things better for people who follow you? You have to answer that with YES and have a good argument to back it up.</li> Trust is the foundation of Leadership, don't lose it</li> People don't follow leaders by accident; they follow people they respect.</li> Good leaders do what is right, even in the risk of failure and the face of great danger</li> The interests of the leaders reflect in the kind of people attracted to the company. It's the law of magnetism.</li> It's a good thing that people with the same level of energy attract each other. Someone with a high level of energy will find the low-level person to be very slow and the low-level person will find the high level to be insane</li> For leaders to be effective, they have to connect with people, not be indifferent</li> As a leader or Speaker, think about others, not yourself when talking to them</li> Influence people who influence others</li> Empower people to do what has to be done, even if they will do your job. Making yourself dispensable is what make you indispensable</li> People do what people see. The better the leaders' actions, the better the people</li> Leaders should be more like tour guides than travel agencies. They have to guide their team and show how to move forward, not just send them to places he has never been</li> People buy the leader first, and then they buy the vision. If they don't buy the leader or the vision, they will look for another leader</li> Use the Pareto Principle for your priorities. Out of 10 tasks, 2 of them will probably bring more return than others</li> If you can do something, it doesn't necessarily mean that you have to do it. You can either not do it or delegate</li> There's no success without sacrifice (time, energy, money, etc.)</li> Legacy comes when you empower people to do things without you</li> </ul> Review of Radical Focus: Achieving Your Most Important Goals with Objectives and Key Results Unknown — Thu, 20 Dec 2018 00:00:00 +0000 Book: Radical Focus: Achieving Your Most Important Goals with Objectives and Key Results</a> by Christina Wodtke. Rating: ⭐️⭐️⭐️. This one is hard to rate. I'm not sure if I liked it or not, and it's probably related to the structure of the book. It starts as a non-fiction/business book, as I expected it to be, but out of nowhere, it became "a novel" (big quotes here). This "novel" part was not too bad, I liked it in the end, but it was totally unexpected. I really like The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win</a> which follows the same idea of narrative, but the whole book was created with that goal in mind. When we get this structure out of the way (or if you expect that from the beginning) the book is good. It shows how OKRs work in a simple way and gives you some examples to help you implement it (or not!) in your own company. Here are my raw notes about the book: The O in the OKR is for those who are not numbers people. The K and R brings the numbers</li> The important x urgent matrix</li> We should focus on important and urgent tasks. We should also spend time on important and not urgent, but not on urgent but not important ones.</li> We should time constraint things that are important but not urgent to make them urgent</li> The OKR set goals, the weekly priority help you to reach them</li> You don't want people to work more, you want them to work on the right things</li> List three things you have to do this week to meet the objectives. These are your priorities</li> Weekly report with a confidence level to reach the goal. It should be discussed in case it looks wrong</li> You should not add all your tasks in the weekly report, just the 3 p1 and one p2. The goal is not to tell people everything you've done, but to let them know about the important things or things they should want to be aware of</li> By repeating the goal on every weekly meeting, you keep it on people's minds</li> Urgent things get done because we feel the urge of time. We have to bring the urgency to other important things</li> You WILL fail in the first time you try to implement OKRs</li> Before starting OKRs you have to have a good and clear vision in mind</li> O is qualitative and KR are quantitative</li> The objective is something that makes people want to get up of the bed to make things happen</li> KR answers the question: how do we know if we met the objective?</li> In companies where failure is punished, employees learn not to try — 💭 OMG, I saw it so many times... so true.</li> There are always many interesting things you can spend your time on, but you have to focus on the objectives</li> Focus your OKRs on the product team level. Focus the individuals on the product teams' objectives</li> Set the mood of the status meeting as a team trying to help each other to reach a common goal instead of individuals trying to prove the reason for their existence in the team by posting everything they did (not just the priorities)</li> When doing MVPs, you can change objectives to hypothesis and try to prove or disprove them at the end of the cycle</li> Set OKRs for a week or a month</li> </ul> Review of Sapiens: A Brief History of Humankind Unknown — Thu, 20 Dec 2018 00:00:00 +0000 Book: Sapiens: A Brief History of Humankind</a> by Yuval Noah Harari. Rating: ⭐️⭐️⭐️⭐️⭐️. One of the best books I ever read. The amount of information here is huge. There are many things I did not know about the history and some possible explanations about where we came to the current state. I really like the way the author says "we don't know this yet". Sometimes, we just don't have the answer but we have many proposed theories, so he talks about them and lets you reach your own conclusions. The way he abstracts religion is really interesting. It doesn't matter what religion is "the right one", he abstracts it as a concept and it works really well for the book. It was hard to listen to this book. I usually listen to books while doing other things but for this one, I had to stop to think/take notes sometimes. I will definitely read this book again in the future and I recommend everyone to read it. Here are my raw notes about the book: Sapiens are born prematurely when compared to other mammals. Children had bigger heads, which caused many problems in birth, so evolution did the work</li> It takes a tribe to raise a human</li> Long intestines and large brains are big energy consumers, so it's hard to have both. The rise of cooking may have helped to reduce human intestines.</li> Thanks to cooking humans are now able to consume much food that was not consumable otherwise</li> The power of an animal is usually related to its body (wings, muscles, teeth). The domestication of fire brought humans a new kind of power. One single woman was able to burn down a forest in a matter of hours</li> 💭 is it right that what separates species is the ability to generate fertile offspring?</li> Tolerance is not one of the Sapiens' traits — 💭 This is more visible than ever</li> Only humans can think and describe fictional entities. You can never convince a monkey to give you a banana by promising him to 6 bananas in monkeys heaven</li> Gods and legal entities are the same sorts of abstract concepts that exist because people believe them. Because of that idea of abstract concepts, society could evolve so much.</li> A trade cannot exist without trust</li> One Neanderthal would probably beat a Sapiens, but a large group of Sapiens will probably defeat a large group of neanderthal</li> Homo sapiens may have been the destroyer of the mega fauna in Australia</li> Wheat kinda domesticated homo sapiens. Humans decided to cultivate wheat because it can bring much more food per unit of territory.</li> As the success of a company is measured by the amount of money in its bank account, the success of a species is measured in the number of spread DNA</li> The worker man in the agricultural age worked far more hours than a forager</li> We created many tools to save us time and provide a better life. Communication is one of them. It took many days to write a letter and leave it at the post office. Nowadays you can send a text message to someone on the other side of the world and receive a response in minutes. It also made us more anxious and less organized to write carefully crafted texts.</li> With the beginning of the agricultural revolution, it was not that simple to move to a different place as everyone started to keep many objects in their houses and became attached to them. The agricultural revolution was a big trap.</li> The creation of myths was very important for the creation of modern civilization. It was the missing glue to make thousands of people work for a single cause. Many kinds of myths that only exist in human minds: law, constitution, religion, money, hierarchy, happiness, etc.</li> Happiness doesn't exist in biology. There's no evolution of happiness by biology terms</li> There's no chance gravity will stop working tomorrow because people stop believing in it. The same thing doesn't apply to any myth.</li> Humans are equal not because someone says so, but because God created them in that way. People are unequal not because Hammurabi said so, but because his God said. The free market is the best economic system not because Adam Smith said so, but because these are the immutable laws of nature. — 💭 🤔</li> The way we organize our children's rooms today shows an individualistic society.

Gender is related to how society perceives an individual it a man or a woman.</li> We still don't know why a man has more social privileges than a woman. There are some animals lead ky female. The muscle power explanation is not totally accepted as well</li> Animals never tried to conquer the whole world but we, Sapiens, tried many times. We tried with money and markets, with conquerors and empires, and with religion and faith.</li> In the Soviet Union, they tried to distribute products to those who need while gathering these products from specialists. In theory, everyone would have everything they needed, and everyone would work on what they are best. In practice, everyone was working the minimum and trying to extract the maximum.</li> Denarius was the first coin, and it still inspires the name for our money (Dinheiro in pt-BR)</li> Sapiens are xenophobic; there was always a sense of "them" and "us". Sometimes they become us throughout the time</li> To spread the good word, the gospel</li> Catholicism never let polytheism go and it still has many "other gods" called saints.

It probably happens because God is too distant for people to relate</li> The average Christian believes in monotheism (god), polytheism (saints), dualism (good and evil), and some animist legacies</li> Buddhism is about stopping craving so that you can live a satisfying life. It's not about worshipping gods, but many Buddhists still find gods (Hindi, Japanese, Tibet) to worship and get help from</li> Ideologies are not that different from religion; both are beliefs in abstract concepts</li> Socialism is humanism, they believe in human</li> There are two types of chaos.

Enters consumerism.</li> Consumerism was able to convince everyone that buying more things is good for you while frugality is self-oppression — 💭 so true</li> In the past, the poor took care of their money while the rich spent it deliberately. Nowadays, it's the opposite, where people buy cars and television (and other stuff) they don't really need</li> As it was in the past, society is still divided into two casts, the poor and the rich. For the system to continue working, the rich should keep investing, and the poor should keep buying. It's the first religion where people can do what they are expected to do (not live a tough life as Jesus or Buddha), so they can get to the promised heaven that they see on the television — 💭 that was tough to hear...</li> Frugality is a disease to be cured in a consumerist society — 💭 so sad</li> Industrialization was the one responsible to set time for everything. In the past, every shop did their own products end to end, but nowadays, there are many people to make one product. If someone gets late, the whole production gets late, so time is important. This mindset was then passed to everything.</li> There were no synchronized clocks between cities in the past; every city had its own clock time. When the first trains started to run, they had time to leave but no time to arrive.</li> The radio was the first instrument to help everyone to synchronize their clocks (and we still broadcast it as the first thing...). BBC used to live broadcast big ben.</li> Peace is more lucrative than war nowadays. In the past, one invader could take the land or treasure from one place, but it's not the same anymore. The value today is in different things. If China invades California, it will not be able to "take Hollywood" or Silicon Valley because the value is driven by people, not goods.</li> Families and community seems to have a greater impact on our happiness than money and wealth</li> happiness is not easy to measure. If you get a daily routine of someone who just had children, you will see that they're not doing things that bring happiness (cleaning, washing dishes, waking at night, etc.) but they still consider their children as the center of their happiness. It's possible that they can't measure their own happiness accurately, but maybe it's just not measured in this way</li> Having children for some people is connected to a view of meaning. Believing you're living a meaningful life is what brings you happiness.</li> </ul> Review of Meet the Frugalwoods: Achieving Financial Independence Through Simple Living Unknown — Mon, 26 Nov 2018 00:00:00 +0000 Book: Meet the Frugalwoods: Achieving Financial Independence Through Simple Living</a> by Elizabeth Willard Thames. Rating: ⭐️⭐️⭐️. I follow their blog for a while now and like it a lot, but I didn't have the same feeling with the book. It was interesting to read that they felt themselves to be privileged when comparing to the rest of the population. Financial independence is not for everyone but frugality can be and that's what they tried to say, IMO. Many of their personal experience doesn't resonate with me at all, but some others were interesting to read. They are real finance nerds and I admire that. I found the book to be quite repetitive. Sometimes I would take notes just to find I already had a note about that... One of these messages is related to the goal of FIRE, which is not related to stopping working but having the freedom to do whatever you want without depending on a paycheck. You can still work if you want. Hope it's clear enough for everyone. At the end, when I finished the book I just said: meh. I will keep reading their blog though. 👍 Here are my raw notes about the book: Money doesn't buy everything, but it buys the freedom so you can do whatever you want</li> Hedonic adaptation, when you get back to your previous happiness after a peak of happiness for having something new</li> Comparing eat at a restaurant every day for them with having 10 houses for a billionaire — 💭 weird comparison</li> Once you start frugalizing it's almost impossible to stop. It becomes a game and a challenge — 💭 totally relate to that!</li> The marshmallow study mentioned again — 💭 even when it was debunked</li> How can I find someone to take care of my dog for free? Let's create a community of dog owners and we can take care of each other.</li> This is not about how much you love or hate your job but how much you depend on your paycheck</li> The only right answer to not quit your job is: "Because I love my job and I don't want to quit". If the answer is not that, your should start thinking.</li> Allow frugality to help you having a financial life you can easily sustain</li> Avoid payments with interest (like car buying, which should be paid ie cash, and used ones if you value the money), the interest should work for you.</li> How would we spend our time and money if we had the freedom to choose</li> We work for the intellectual fulfillment, not because we need the money</li> It's not about moving to the woods or quitting your job. It's about liberating yourself about the reliance on a salary your job provides</li> A lot about privilege. You can save by being frugal if you don't earn enough to live properly.</li> "I chose to be frugal to reach financial independence but I already had a good education and people helping me."</li> Billionaires and poor people were really obsessed with money for two different reasons. I realized I want money to not be that important</li> "This extra expending was not increasing my happiness at all"</li> </ul> Review of The Power Of Less: The Fine Art of Limiting Yourself to the Essential Unknown — Mon, 12 Nov 2018 00:00:00 +0000 Book: The Power Of Less: The Fine Art of Limiting Yourself to the Essential</a> by Leo Babauta. Rating: ⭐️⭐️⭐️⭐️. It's a good book. It's repetitive and a bit outdated (I heard Google reader somewhere) but all the hints here are still valid. To summarize: the focus is everything. Chose something you want to do and do it. Remove everything else that's not moving you toward your priorities and do what you have to do. He lists some actionable that can help you on this journey, but there's no miracle here (as expected), you just have to focus and get things done. For me, it was a bit repetitive because I already read about almost everything he says in this book, but I would recommend reading if you're not into minimalist, productivity, and focus. Here are my raw notes about the book: Focus on the essential, eliminate the rest</li> Do less but better things. Focus on quality, not quantity</li> Set limitations, it will help you to simplify to the essentials</li> Do fewer things but focus on the ones with the most impact</li> Look at your tasks and prioritize the ones with high impact</li> Apply limitations to every aspect of life to force yourself to make choices and choose the essential</li> Follow your values when deciding what is essential. What is more important to you?</li> Second question to find the essential: what are your goals?</li> Third: What do you love?</li> Four: what is important to you?</li> Five: what has the biggest impact?</li> Six: what has the most long-term impact?</li> Seven: needs vs wants. It's a good criterion when you're deciding to spend. What do you really need? These are the essentials, The wants you can eliminate if you want</li> Eight: eliminate the non-essential. Example: wash the car and pay the Bills. You can totally eliminate wash your car and focus on the payment — 💭 so... thinking like that you will never wash the car...</li> You can apply these questions in many areas of your life: what commitments in your life are essential? Use the questions to prioritize your goals, you can always get back to the other goals later</li> Remove tasks that are not important, delegate the ones you can delegate, and focus on the essential</li> To get into the state of flow, wind something you're passionate about, and then get rid of distractions for a period of time</li> When people want something but you don't think it's essential, learn to say no. Saying no is the prioritization of the essential. Make your reasoning clear and they will respect your time and appreciate your respect for their time.</li> Shut down everything and focus. If you feel the urge to check your email (or any other external thing), stop, take a deep breath and get back to the task</li> If some idea comes up when you're focusing, write it down to your inbox and get back to the task</li> Process your inbox every predetermined interval, between one task and another</li> Become aware of your thoughts. Awareness brings change. Don't beat yourself about it, be aware, let them go, and focus on the present</li> Focus on one thing. If you're walking, just walk and feel the present.</li> Reporting your progress to a group of people helps. When you see a group of people doing great, so can you</li> Set your MITs (most important tasks) every morning. Make this a habit.</li> Check email just twice a day</li> It's better to have a small but constant improvement than a big one. Small improvements tend to last because they become a habit</li> Start with just a small task of a project instead of trying to tackle everything at once</li> Declutter your desk and your life. Do it in small steps</li> Achieving a goal takes energy, focus, and motivation. All of them are highly requested virtues nowadays</li> If a goal is too big, break it into sub-goals. Instead of "become a lawyer" use "get into the law school". No more than one-year goals.</li> Add 3 priority tasks to your list every day, and at least one must have an MIT that moves you towards one of your goals. Do it as the first task, in the morning. Whatever else you accomplish will be an extra.</li> The stacking pager doesn't work. Use a file and a simple alphabetical system to file. File it right away.</li> Take an inventory of your commitments: work, side-work, family, kids, city, religion, hobbies, home (stuff to do at home), online communities, and others</li> Create a shortlist of things that contribute to your life and values. Leo's list includes 1. Spend time with his life and family. 2. Writing 3. Running 4. Reading. These are his essential commitments, what are yours?</li> Eliminate non-essential commitments so you will have time for your essential commitments</li> Don't try to eliminate everything at once. Eliminate one by one, starting with the easiest one</li> It's hard to say no to other people, but keep in mind that every request is a demand of your time and your time is limited, so you have to spend it on what matters most to you</li> If you're a morning person, use your morning to get things done. Use your evenings to plan for the next day, declutter, organize, wind down, write, read, be grateful, etc</li> Train your focus to accomplish more. A good exercise is meditation. Do some meditation sessions where you will just close your eyes and focus on your breeding</li> How to focus:</li> Chose the work you love</li> </ol> </li> Chose important tasks to do</li> </ol> </li> Chose tasks with the right difficulty. If it's too difficult, you will not understand it enough to be able to concentrate</li> </ol> </li> Find your quiet peak time. The time you will have a quiet environment and peak energy</li> </ol> </li> Clear away distractions to focus</li> </ol> </li> Take the time to appreciate what you've done after your focus time</li> Drive slow, eat slow, have a good diet and exercise routine</li> To help with motivation, don't start things right away. Set a date and get excited about it</li> Do not miss two days in a row.

To do that, I'm using the qmk_firmware</code>. I'm adding a new file as a layout (link here) and I have to change tmk_core/common/avr/bootloader.c</code> to be able to compile it: -uint32_t reset_key attribute ((section (".noinit"))); +uint32_t reset_key attribute ((section (".noinit,\"aw\",@nobits;")));</code></pre> After that, I just had to get the keyboard to the reset mode via fn + ESC</code> (to change the layout) and then pressed the RESET button. I had to refer to the map for the current layot to find the keys but after that, it went smoothly. To compile the firmware you want, just use make</code> and specify the keyboard and layout: make keyboard=atreus keymap=pothix</code></pre> In this case, I have a keymap called "pothix" at qmk_firmware/keyboards/atreus/keymaps</code>. To flash the firmware, I used the avrdude</code> command: sudo avrdude -p atmega32u4 -c avr109 -U flash:w:atreus_pothix.hex -P /dev/ttyACM0</code></pre> The result will be something like: Connecting to programmer: . Found programmer: Id = "CATERIN"; type = S Software Version = 1.0; No Hardware Version given. Programmer supports auto addr increment. Programmer supports buffered memory access with buffersize=128 bytes. Programmer supports the following devices: Device code: 0x44 avrdude: AVR device initialized and ready to accept instructions Reading | ################################################## | 100% 0.00s avrdude: Device signature = 0x1e9587 (probably m32u4) avrdude: NOTE: "flash" memory has been specified, an erase cycle will be performed To disable this feature, specify the -D option. avrdude: erasing chip avrdude: reading input file "atreus_pothix.hex" avrdude: input file atreus_pothix.hex auto detected as Intel Hex avrdude: writing flash (22090 bytes): Writing | ################################################## | 100% 1.69s avrdude: 22090 bytes of flash written avrdude: verifying flash memory against atreus_pothix.hex: avrdude: load data flash data from input file atreus_pothix.hex: avrdude: input file atreus_pothix.hex auto detected as Intel Hex avrdude: input file atreus_pothix.hex contains 22090 bytes avrdude: reading on-chip flash data: Reading | ################################################## | 100% 0.20s avrdude: verifying ... avrdude: 22090 bytes of flash verified avrdude: safemode: Fuses OK (E:C8, H:D0, L:FF) avrdude done.

Rating: ⭐️⭐️⭐️⭐️⭐️. What a great book! The best part of this book is that there's nothing so out of this world there, they are just talking about what we should be doing. Hey, it's true, it doesn't have to be crazy at work. We can still do our best and deliver an amazing product without making ourselves miserable working like crazy to meet some made-up numbers used as "goals". We can still be ambitious and make something our users love without driving the whole team crazy. We can have a productive environment to let people do their work in the best way possible. Here is my raw notes about the book: Having a calm and productive environment is a choice.</li> There are many great tips in this book and I already saw a situation where the solution proposed would apply. Here are my raw notes for this book:</li> People can't get the work done at work anymore</li> The answer is not more hours, it's less bullshit</li> You can have a calm company too. Chaos should not be the norm at work</li> Do you know where the money comes from? Customers. Not any [[venture capital]] or something like that.</li> Calm is reasonable expectations, 40 hours work week, smaller, visible horizon, meetings as a last resort, async first and real-time second, profitability</li> "The goals don't care about how you feel" — 💭 what a weird way of thinking</li> Your work is not to love or war, it's business. If you think you're a commander and have to exterminate your enemy, you will do any dirty trick to get there. No morals.</li> It doesn't matter how much market share we have. Do we have enough money to pay the bills and have some profit? Are we growing? In case both answers are YES, then we are great.</li> At the end of the day, would you prefer to win an imaginary contest by throwing sand in the eye of your competitors or by doing the best product you can?</li> Our goals? No goals! Just be profitable. We care about our products and customers, and we get better every day. We just don't care about having specific goals.</li> They tried it once, but it was just an incentive to pretend they care about a number they made up. It's also not worth it to take the cultural trade-offs just to have it.</li> Let's face it: goals are fake. They are just artificial targets for the sake of setting targets. They are a source of stress.</li> There's a dark side to goal-setting: companies sometimes lost the integrity to reach those numbers. "Let's reduce quality to deliver."</li> If you stop thinking you have to change the world, you will lift a burden from your shoulder and everyone else working with you</li> You don't have to feel discomfort all the time. Sometimes discomfort is painful, but it's needed, but not all the time. Sometimes, if you're uncomfortable, it's because something is not right. — 💭 I'm not sure if I agree 100% with the arguments here. The argument on discomfort happens, but it's not the same for "pushing yourself harder". I think that pushing yourself harder is where you get the most out of what you want, but I also agree that having "push yourself harder" as a corporate strategy doesn't seem very healthy and that's probably the point of this argument.</li> Sometimes is not breaking out but driving deeper</li> You don't need more than 40 hours. You need to remove useless interruptions and actually work 40 hours. Be a protectionist but remember to protect what matters most</li> When was the last time you had 3 or even 4 hours of uninterrupted work?</li> Effective is better than productive. Don't focus on being busy, but being effective on what you do.</li> Not doing something which is not worth doing is a fantastic way of spending your time</li> When people have to get something done, they leave the office. The office doesn't make much sense anymore.</li> Office hours are the time when you will be available for people to reach you and ask questions. Questions can wait</li> I don't care about what people are doing at this particular moment, I care about the work they are delivering.</li> It's important to know the status of people during emergencies but 1% of the time should not drive and become a rule. Assume that people are focusing on their work.</li> Companies are not families, they are supporters of families</li> It doesn't matter what you say, it matters what you do. Don't let your managers overwork and don't do it yourself. Be calm as you want your company to be</li> The owner's word weighs a ton. Any comment or suggestions from the owner can make something to become a priority. Things like "it's just a suggestion" don't work.</li> Be careful with low-hanging fruits. Many of them look low when you're not close enough. Take special care when you're assigning someone else to take care of it, you may be setting this person to fail.</li> Be careful with sleep deprivation the bad parts are not always easy to notice, but they affect the whole team.</li> Benefits who? Offices with game consoles, free dinner, etc. benefit the company, not the employees. Staying in the office longer than you should is not a benefit</li> Paid vacations for employees that have more than one year working for Basecamp. They also pay the travel for this person up to 5000. 32 hours work week in the summer so the employees can have a 3 days weekend. 30 days paid sabbatical every 3 years, to do whatever you want. 1000 USD a year for education, not just related to work. Donation match, if you donate until 2k USD, the company also donates the same amount. Fresh local vegetable expense. 100 for exercises. Not a single benefits to keep people at work</li> Library rules. Make your office look like a library, where people go to study and get things done. It may have one room for noisy conversations, not the whole place</li> No fakations (fake vacations)</li> If we don't clearly communicate why you terminate with someone, people will start finding a reason for themselves</li> Saying goodbye is not easy, but it doesn't have to be cold. There should always be a message about what happened and the reasoning for leaving, either from the person leaving or their manager</li> Real-time chatting can be a problem because of FOMO. If you're not reading all day, you may miss something important and not have the chance to give your two cents</li> If it's important, slow down. Don't process essential things one line at a time, write words down and discuss it.</li> Real-time chatting is excellent as a small slice not a whole pie of communication</li> If there's a deadline, we keep the date, but the scope may change. We keep the must-have things and cut what can be cut. Adding more work after the deadline is unfair, we just reduce it after setting the date.</li> A deadline with a flexible scope is better than an estimation. People suck at estimates.</li> Culture is what you do. Do the right things.</li> Disagree and commit. Don't try to convince everyone, it's impractical. Someone should be responsible for decisions but everyone should be heard, and they need to feel it.</li> Have less to do instead of struggling with time management. Learn to say no.</li> Parts of your revenue just don't worth it. Sometimes it's better to trade some revenue for your time (receiving payments in checks)</li> It's OK to take risks but not high risk all the time (double or nothing)</li> We always kept ourselves profitable with a positive account. It's hard to be calm when you have a negative account or is almost going out of business</li> Keep the same price for all customers. It doesn't matter how many accounts they will have, they will be just another client, and your support and features have to be great for all of them. By doing that you avoid having special changes for one client or be tied to them because of the high volume of money</li> Launch and learn. Beta processes take a lot of time and effort, let the market tell you their feedback</li> When something is wrong with your product, help your client to reach the "not a big deal conclusion". Most of the time it's not costly to do that, and the feedback from your service will be astonishing comparing with it may be. Example: bad air conditioning in a hotel room. You could provide a refund, cold water, ice cream, and help the customer find another hotel nearby. This attitude will probably trigger a "not a big deal" reaction to the problem.</li> A calm company is a choice, make it yours.</li> </ul> Review of Principles Unknown — Fri, 05 Oct 2018 00:00:00 +0000 Book: Principles (Summary)</a> by Ray Dalio. Rating: ⭐️⭐️⭐️⭐️⭐️. I was between 4 and 5 stars for this one. I would say I would rate it with 4.5, but when I was editing my notes I realized the big number of notes I had and decided to go for 5 stars. There are many good ideas in this book and many of the things I see here are logical. If you're a logical person (instead of an emotional one) you will understand many of the strategies he describes in this book. Keep in mind that you don't have to agree with his way of doing things, that's not the point. This book was written to spread the word about what he did and went good and bad. There are many discussions about meritocracy and this book is something like a study case in my opinion. Writing down your principles and letting everyone know is a great idea, especially if you're the head of a company. Here are my raw notes about the book: Sometimes we get principles from our parents or accept a holistic package of principles that come together with religion or legal frameworks. We have our own goals and nature; we should choose our own principles</li> Instead of thinking: "I am right" think "Why am I right?"</li> Learn how to weight people's input to have your own opinion based on that</li> Write down your principles, especially if you are working with others</li> Time is like a river that guides us to encounters with reality. We can't change its course but deal with it in the best way possible</li> While making money was good, having meaningful work and having meaningful relationships was much better. It’s senseless to have to make money as your goal as money has no intrinsic value.</li> It's important to visualize the economy as a complex machine and think about all its parts separately</li> I don't like to work with people who put a facade of politeness. People should say what they think it's bad when it's needed. Operate in any other way would be unproductive and unethical</li> There are two kinds of people in the workplace. The ones who work for a paycheck and the ones who work for a mission.</li> Seek out the smartest people who disagree with me so I can understand their reasoning</li> Baseball cards for the company employees so you can give the right task for the right person. They will do it better and feel satisfied doing it. In the beginning, it had some pushback, but it was well accepted afterward and studied by behavioral specialists</li> The company grew fast for a long time and used bleeding-edge technology, but they were not rock-solid and had to invest some effort to make things better</li> Smart people working with good systems and computers are the key to success</li> Shapers are people who change things. Albert Einstein changed science, Jesus Christ changed religion, etc. It's important to identify shapers when hiring, especially if you're looking for a change</li> Things happen over and over again throughout history. It's important to learn from it and be prepared for the next wave</li> Many important philanthropists (like Bill Gates) received a diagnosis of "not caring for people." That happens because they usually have their goals as a top priority, even if it means someone not being happy about the decision</li> The life is like a game where every problem is a puzzle you have to solve. When you solve it, you receive a gem that will help you with the next puzzle (gem == reflect about the solution)</li> Be radical open-minded and radical transparent</li> Every time I see something in nature that I (or humankind) think it's wrong, I assume I'm wrong and try to understand why nature is right</li> Nature optimizes for the whole, not for one individual</li> People kill each other in the name of their religion, both thinking they are doing the right thing</li> Contribute to the whole, and you will probably be rewarded</li> We are everything and nothing at the same time. Everything to ourselves, if we die everything is gone. Nothing in nature, just another human among billions</li> When something you don't like happens (rain, weaknesses, death), remember that nature optimizes for the whole, not for yourself.</li> We always transform. We are made of other elements, grow, die, and become part of other things. The whole of nature works like that.</li> Don't be embarrassed about your problems. Everyone has them. Talk about them openly and improve yourself.</li> Your future depends on the choices you're making now. Something that's painful today may be something common in the future. You have to adapt to the situations you have.</li> People who underestimate the second effect of things usually have bad outcomes. In exercises, the first effect is the pain and time spent, and the second effect is the health and good appearance. People usually neglect the first and lose the second as a consequence</li> It doesn't matter what kind of situation you're facing. You can still be happy if you face it in the right way because there are many paths to happiness</li> People who have an internal locus of control outperform those who don't [check source]</li> Don't worry if you like the situation or not; life doesn't give a damn if you like it or not</li> You can't excel on everything (don't have Albert Einstein on your basketball team). Find your weaknesses first and then decide if you want to convert them to strengths or decide to find someone else to do it. You're the planner and the worker of your life, and you can still manage how (and by who) some tasks are done</li> Don't worry about looking good but about achieving your goals</li> If you set your goals for things you know you can achieve, your setting the bar too low</li> Write down your plan and write it down to everyone to see and measure your progress against</li> Great planners who don't execute the plan go nowhere</li> Develop good work habits. Have a prioritized todo list or something like that</li> Establish clear metrics so you can estimate your progress</li> Have an open mind everyone has blind spots, and it's ok to reflect and change your mind</li> To be open-minded, you have to sincerely agree that you may now know the best path to follow</li> Open-mindedness is considering that you may be wrong and encourage others to tell you</li> Prioritize what you spend time on and with whom you're arguing</li> It doesn't pay to be open-minded with everyone, chose people you respect. The most believable people you have access to.</li> You might agree to disagree if you find an impasse.</li> Open-mindedness triangulates with believable people. He got three different diagnoses from three different doctors, but when they discussed with each other, they got to a conclusion that led to the right diagnosis of the possible disease.</li> Surround yourself with open-minded people, and you tend to learn a lot in the process</li> Don't let your lower-level control the discussion. Take some time, think about it, and use open-minded thinking to the debate</li> If a bunch of believable people is telling you that you're wrong, start asking questions to understand why is that. Consider that you are indeed wrong, and challenge your assumptions</li> Remember: it's not an argument, it's an exploration of what the other person is saying — 💭 The Socratic method?</li> Bipolar disorder is related to the chemicals in the brain. It doesn't make sense to be angry with a bipolar person because he/she is not thinking logically because of these chemicals</li> Rewire your brain to love learning and get the positive rewards from it. — 💭 I would love to have had help with that when I was a child</li> Planners vs. perceivers: Planners stick to the plan while perceivers like to adapt to the environment.</li> Thoughtful disagreement and open-mindedness</li> My objective, in the beginning, was to have fun at work with the people I like. I was looking for meaningful work and meaningful relationships.</li> The better we are with each other, the toughest we can be and the better will be our personal growth</li> There should be no hierarchy in the giving or receiving of criticism</li> Make your passion and your work the same and work with people you like towards it</li> You have to work in a culture that fits you and also produces the outcomes that will keep you motivated</li> There are no worse things in leadership than to hold up false truths and then be swapped away</li> Threat one person with different rules than others is an insidious way of working with goes against meritocracy</li> Dishonest people are dangerous, and it's not very smart to keep them around</li> Strive for the majority of your community to have meaningful work and meaningful relationships but consider a minority to go against the community</li> The best students are usually the ones who have a hard time learning from their mistakes because mistakes for them means failure. People who learn from their mistakes usually outperform those who don't</li> Open-minded people usually ask many questions and want to be with people who know more than them. Closed-minded people want to tell you what they know, even if they don't know much. Don't have anything to do with closed-minded people</li> It's ok to disagree. People can have wonderful relationships even if they don't agree on many things</li> Believability weighted answer. People with more knowledge on the matter will have more influence in the voting</li> Disagreeing has to be encouraged, but people must know how to disagree well</li> Companies don't make decisions, people do. Think about the people and culture in the organization.</li> When hiring, think about values, and skills, in this order. People fight for their values. Abilities are about ways of thinking and behaving. Some people focus on the details while others have the ability to see things at a higher level.</li> Values and skills usually don't change much, but skills can be learned in a limited amount of time</li> If you're less than excited to hire someone, don't do it.</li> Don't hire people for the short term, hire people you want to share a life goal</li> Hire people who have smart questions instead of pretending they have all the answers</li> Be generous to people and expect them to be generous to you.</li> Provide constant feedback to the person you're mentoring will understand what is expecting and how is his performance regarding that</li> Don't confuse what it with what to do about it when receiving feedback. These are two separate things</li> Evaluate employees with the same rigor as you evaluate job candidates</li> What I worry about is doing the right thing, not what people think about me</li> You are responsible for your work even when you go on vacation. Nominate someone to continue the work and, if needed, take some time to keep the ball running — 💭 I do not agree with the ladder</li> When mitigating a situation with a subordinate, start with what you expected from the situation and then ask them to describe what happened.</li> When evaluating the "process machine" ask yourself "who should do what differently."</li> Drill down: list all problems and people involved. Get to the root cause (ask why to every question until you get there)</li> It's important to make your most important principles into actions</li> Companies are the opposite of buildings. The company foundation relies on the top, not the bottom. Hire great managers and directors to build a great base</li> What out for department slip. A support department should know the goals of the people they are supporting and not mandate how they are supporting. They will know the goals and provide feedback on how things should be done, but they should not provide the vision</li> When someone breaks the rules, you should let everyone know about the consequences</li> Technology is great for leverage. Document training and most common questions in audio, video, or text. Assign someone to organize it on a regular basis, just like a manual</li> Good people with good technology usually bring great productivity</li> It's better when people know each other's strengths and weaknesses so the group can adapt to it</li> Have protocols to help people achieve their goals. One example would be providing a template to tell people one way to proceed with the work they will receive. You should have a way to produce the internalized learning required.</li> Final points: make your passion and work the same. Struggle well along with other people to meet your goals. You will evolve quickly and contribute to the overall evolution in a significant way.</li> Daily update tool: all people reflect for 10 or 15 minutes about what they are working on, and it is working. By triangulating this, a manager can get the feeling of his environment.</li> </ul> Review of 1984 Unknown — Thu, 20 Sep 2018 00:00:00 +0000 Book: 1984</a> by George Orwell. Rating: ⭐️⭐️⭐️⭐️. I was between a 4 and 5 stars for this book and decided to go with 4. The ideas behind this book are amazing, especially when you read a little bit about Orwell and the political scenario of the time. It is a criticism of many things but it's still an interesting construct of what may happen in a very extreme scenario. The whole idea of creating a language to limit how people describe things and how they think is a really interesting concept. As a novel, it's not that good. You don't care much about the characters and just one or two are really strong, and this is why I decided to not review with 5 stars. Other than that, I would definitely recommend this book to everyone. Bonus: If you ever listened to "Testify" by Rage Against the Machine, you will recognize part of the song in the book. ;) Review of The Lay of Aotrou and Itroun Unknown — Wed, 29 Aug 2018 00:00:00 +0000 Book: The Lay of Aotrou and Itroun</a> by J.R.R. Tolkien. Rating: ⭐️⭐️⭐️. It's an OK book if you're a Tolkien fan. For those who like Tolkien and everything he researched, it's an interesting book to read. I would not recommend this book to someone who's not into Tolkien. There are three poems in this book and it tries to tell a story about how Tolkien wrote the final poem. None of them are that great alone but together they show one particular part of Tolkien's style of writing/researching. Review of Tolkien and the West: Recovering the Lost Tradition of Europe (The Modern Scholar) Unknown — Sun, 22 Jul 2018 00:00:00 +0000 Book: Tolkien and the West: Recovering the Lost Tradition of Europe (The Modern Scholar)</a> by Michael D.C. Drout. Rating: ⭐️⭐️⭐️⭐️⭐️. A great book if you are a fan of J.R.R. Tolkien (like me). I read 10+ J.R.R. Tolkien books already. I really like the descriptive way of writing and the whole fantasy world he created. I also read some other books that are not related to middle earth. With that said, it was amazing to me to find so much that was not explicit in the story. I know Tolkien was also a professor at Oxford and many of his studies influenced (or were influenced by) his fiction, but this book brought much more context to it. I was also aware of part of Tolkien's context but I could not relate the background of some characters to some of the real-world "problems" we have/had. I cannot confirm all references for this book but I have to say that everything makes sense for me. I have to admit that I did not have big expectations for this book and it surprised me in a good way. If you like Tolkien's work, I would definitely recommend it. Here are my raw notes about the book: The west for Tolkien was more related to happiness. Considering his geography, it's more related to wales than Germany (consider world war II)</li> When Thorin dies, he says that he will leave a ton of gold and silver behind but wants to part in a friendship with Bilbo, which he calls "children of the west" at that moment.</li> Bilbo is a "child of the west" because of Western culture valuing more food and drink than hoarding gold. It's not that he doesn't value gold, but he prefers to spend it to be happy instead of just sit and look at it</li> Thorin was part of the "heroic" world while Bilbo was part of the western world. Tolkien tries to show that some acts of the west side can change the heroic side. The violence to conquer everything.</li> Tolkien did not criticize nationalism but tried to show something through his stories</li> Smaug is the biggest example of a creature who just sits (literally) on top of its fortune and don't produce or spend wealth on anything</li> Merry, the thoughtful and educated guy ended up with Rohan, the non-hierarchical and non-structured people. While Pippin, the impulsive guy ended up with Gondor, the high hierarchical and structured people</li> The way Théoden dies is a reference to the northern courage. It's the way barbarians fight, even if there's no possible way of winning.</li> Denethor decides to choose his own death time and method, giving up just like Romans. In essence, the Romans gave up when facing the barbarians because, in their perspective, there's no way to win.</li> Frodo knows that Gollum understands him (because he carried the ring before) while Sam cannot do that</li> There was one chance that Gollum will reconsider his plans at Shelob's lair but Sam ruins it by accusing Gollum at the wrong moment. Tolkien said it was one of the saddest moments of the LotR</li> Denethor's death was part of Tolkien's critics of the aristocracy. Denethor only cares about himself. He likes the city because he rules it. When the city was being taken, there's nothing to do. It's concerning when someone can do something bad just because he/she has enough power for it. It's even worse now with nuclear bombs.</li> The fall of Numenor shows Tolkien's thoughts that eternal life should not be pursued in the physical plan but through religion. Try to attack Valinor was a terrible mistake made by the man of Numenor.</li> Most of what Tolkien wrote was related to his scholar work and his studies on old English and Anglo Saxon. His stories helped me to study topics from a different perspective because anything can be created on fantasy.</li> </ul> Review of A Brief History of Time Unknown — Fri, 20 Jul 2018 00:00:00 +0000 Book: A Brief History of Time</a> by Stephen Hawking. Rating: ⭐️⭐️⭐️⭐️. Nice book but not that simple for those who are not engaged with physics. That's not a problem with the book, IMO, physics is complicated. The pacing of the book is really good. He starts with the basics of physics and how paper after paper it is changing. It's interesting how Stephen Hawking puts himself as part of that story, not the center of it. I knew the Doppler Effect before this book, but for some reason, I was only applying it for sound and not for light. It was quite interesting to see the explanation of how we measure other stars via the light they emit. The redshifting effect because of the Doppler Effect is something I never thought about and was a good experience. I have to say that it was quite hard to read (listen, in my case). I decided to not listen at 2.0x as I usually do and even though I had to move back many times to be able to get "in the flow". I don't have too many notes for this book and I think it's related to the fact that I can't explain some ideas I had without adding the whole context to it. To be able to add full context, I would need to understand some other contexts that are not clear enough. I will probably read it again in the future. Here are my personal notes: Aristotle had a thought that the earth is round because the shadow of the moon would be an ellipsis if it was sharp</li> Isaac Newton not only proposed a theory of how objects attract each other but created all the complicated math to validate it</li> Newton came to the idea of gravity when he was in contemplating mood. It's not when an apple hit his head</li> The city of God book, Saint Augustine</li> A theory can be disproved by falsifying just one of its hypothesis</li> When an object is not acted upon any force, it will keep moving in a straight line. It's the first law of Newton</li> Acceleration is smaller the greater the mass (big engine in a heavy car)</li> Newton thought that time and space were two separate things</li> Time is not constant anymore. Now we consider the speed of light as constant and calculate time using it</li> Different elements absorb different specters of life. By using this information we can determine the elements present in that star's atmosphere</li> The Doppler effect also applies to light. If a source star is moving away from us, its color tends to be redder, since the waves are reaching us faster and fave frequency is how we see colors. The same happens with sound waves, the sound changes related to distance (cop sound)</li> All measurements we have from galaxies are red shifted, which means that they are moving away</li> The farther a galaxy is from us, the faster it's moving</li> The current evidence we have shown that the universe will probably expand forever but we're are not 100% sure of that.

Rating: ⭐️⭐️⭐️. I bought this book because I wanted to understand a little bit more about introverts, so I can improve myself and understand others better. In the end, this book is totally related to sales, and part of it was not so interesting to me. I have to say that his method seems to be really good. The example (and testimonial) he shows close to the end of the book proves (at least for me) everything he wrote in the book. It was very persuasive, easy to follow, structured, and good for introverts. The book is good for introverts who have to deal with sales somehow, or for those who don't understand how would it be possible for an introvert to deal with sales. I learned some tricks, but it's not life-changing for my current context. It's worth saying that I highly recommend How to Win Friends and Influence People to everyone I know. It's about sales, but not only sales. 👍 Here are my raw notes about the book: Introverts take their energy from being alone. Extroverts get it by being with people</li> Introverts usually hate chitchat or small talks and rather prefer meaningful conversations. — 💭 YES!</li> People usually tend to work on things they are comfortable with. Engineers tend to look for engineering instead of trying sales</li> Sales is a skill anyone can learn and introverts make the best salesperson</li> Talk to the right person to solve your problem. (or to deliver your sales pitch)</li> Extroverts depend on external forces/people. Introverts follow a plan and depend on themselves only</li> Finland is the country with more introverts</li> For introverts (who hate small talks) it's better to have a plan to execute when small talks are needed. It should consider something you like and works for you</li> Introverts don't rely on personality, and plans beat personality in the long run</li> Don't tell people what you sell. Understand people's problems and offer a solution using what you have to offer</li> Don't win the fight and lose the sale. There's not that much advantage on that</li> Instead of saying that the client is wrong (somehow), use: "this is what happens when "</li> Introverts tend to suffer from anxiety more than extroverts</li> Always have more than one prospects to present your idea, it reduces the pressure</li> When introverts afford to be indifferent, they often get the best deals.</li> Trust is the base of everything else. Gain their trust and empathy before selling anything.</li> Introverts don't like to show themselves explicitly</li> When setting a value for a presentation or something, you should give a hint of your professional experience so they can value you.</li> You don't have to throw them your resume, but give them a hint that you know your stuff and is well positioned in the market</li> Have an agenda before a conversation. You should let him/her know that you know what you're doing and he can trust you to guide it</li> Don't give many options to your customer or it will decrease the chance of him buying something. It's related to the paradox of choice</li> Ask the right questions, in the right order, moving to the heart of their problem, and show you have what they need</li> Get through the gatekeeper. Secretaries and other people who stay between you and the person who actually has the power to make the decision. Be kind and direct by saying what you are selling and asking for who you should be talking to.</li> Tell, not sell. Use stories to get the attention of the buyer, we relate ourselves to stories a lot. "When sleeping, the body is resting but the mind is telling you stories"</li> A story must show why it's important and also where the protagonist was before and what he became</li> Learn decent sales or you may be a hostage of your salesperson</li> </ul> Stats for Jun, 2018 Unknown — Sat, 14 Jul 2018 00:00:00 +0000 Guess what!? Yes, metrics for June! 📊 Books</h3> I usually don't count how many books I read, I just track and check at the end of the month. When I saw that I read five books read this month, my face was like 😱. All of them received a 4-star review, so the result is quite good. </a> Managing Oneself</a>: This is a great book. It's not life-changing, but there are many great tips to improve your life. It was almost 5 stars for me. Check my review to find my notes</a>.</li> A Filosofia Explica as Grandes Questões da Humanidade</a>: This book is in pt-BR, if you speak Portuguese and want a light (and quite funny) introduction to philosophy book, this may be the one.</li> The Hard Thing About Hard Things: Building a Business When There Are No Easy Answers</a>: A good book for CTOs. It was also an excellent reading for me since I saw many of those problems happening during my career 😅. I'm not sure if I'm the right audience, but it's a good book overall. Here is my review and notes</a>.</li> Blood, Sweat, and Pixels: The Triumphant, Turbulent Stories Behind How Video Games Are Made</a>: If you like games, especially what is under the hood (not just to play them) you will have a good time reading this book. I'm a big fan of games and always try to build my own just for fun. The gaming industry is tough, you will understand why by reading this book.</li> Zero to One: Notes on Startups, or How to Build the Future</a>: A good one but I think I had high expectations. I recommend reading anyway, especially if you want to build a startup in the future (or already have one).</li> </ul> Note: I write a full review for all books I read. Sometimes I mention some of them here, but you can find all of them on my Goodreads account</a>. Articles</h3> I'm still experimenting with an integration between Pocket and Google Spreadsheets via IFTTT</a>. I'm adding a tag to the articles I read and want to include in my list of articles read for the month. </a> I use a SUMIF</code> to sum all lines containing the YEARMONTH tag and it shows I got 27 articles read. Let's compare this with the old method: var pocket = {"unread":1539,"unread_pct":2.47,"read":1146,"read_pct":4.36} var uls=document.body.getElementsByTagName("ul"); unread = uls[0].children.length; pocket["unread_pct"] = +((1 - pocket["unread"] / unread) * 100).toFixed(2); pocket["unread"] = unread; read = uls[1].children.length; pocket["read_pct"] = +((1 - pocket["read"] / read) * 100).toFixed(2); pocket["read"] = uls[1].children.length; console.log("# Result: " + JSON.stringify(pocket)) # Result: {"unread":1573,"unread_pct":2.16,"read":1173,"read_pct":2.3}</code></pre> It means I have 1573 articles unread and 1173 articles read. Comparing with my results from the last month (1539 unread and 1146 read), I got around 2.16% more unread articles and 2.3% more read articles. 1173 (read this month) - 1146 (read prev. month) = 27 (the number in the spreadsheet) It seems my spreadsheet tracking is working as expected. 🎉 I have to think if it's a good thing to lose the number of articles added, but I'm not sure if it's bringing that much value in the current situation. Coding</h3> Here are the charts from Wakatime</a> since the last post. I will start with editors this time: </a> Emacs is superior this month. I don't remember seeing any uptrend during the month though. 🤔 </a> It's better than the other months. It's interesting to see that Sunday was one of the days I programmed the most. 🤔 Usually, it's related to my presentations (rehearsing live coding) or writing this blog post, which makes markdown</code> to be on the top of the list of languages. 😅 </a> And now we have a surprise! Rust is the most used language this month with more than 32% of my usage. 😱 The reason for that is my gaming with Rust presentation this month. I plan to do some live coding, in the same way, I did for Python, Javascript, and Ruby in the past. It is taking almost all my spare time, but it's also a ton of fun. Thanks to my monthly posts and lengthy posts on Twist</a> (that I write in Emacs), Markdown is in the second position. Python is my first language nowadays and Ruby is used when I work as a freelancer full-stack developer (for the same company, for more than 2 years now). Speaking</h3> This month I spoke about the same topic as my book</a> at Impacta tecnologia</a>. Still related to this presentation: this month also marks the milestone of 1000 copies of my book sold, which is incredible. I promised to write about it, hope to have a post soon. Completed tasks</h3> Here is the comparison of the tasks for the last month (first) and the tasks for this month (second). I extracted it from Todoist</a>. </a> </a> This time I could take the screenshot at the right time so we can compare. It seems stable, but I can see an improvement there. It is quite unreliable to use the number of tasks as it can be "drink water" or "implement a complex system", but I'm OK with that. 😀 Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 1 days and 8 hours of podcast time. A little bit less than the last month, but as usual, the decrease of time listening Podcast correlates a lot with the number of books read (listen). 👍 Here is the list of Podcasts and their times: </a> I'm not entirely comfortable with this list. It doesn't tell a true story. I listen to many good and small podcasts, and they are not part of this list because the long ones usually take their place. As an example, I listen to CBN podcasts</a> almost every day, but they are just some minutes long. I'm keeping this list here because it shows some of the Podcasts I follow, but I will probably find the best way to do that. I will probably export a file every month and post it here. 👍 Hours working</h3> Here is the data from my time tracking software (Toggl</a>) comparing the last month (first) and this month (second): </a> </a> June 21st I was at AWS Summit São Paulo 2018</a>. I had 19 work days tracked this month, and I worked for 160 hours, which mean that I worked 8 hours more than I should (more than I had last month, which was 5 hours). It's quite bad since I worked 1 day more than I should. The goal is to reach 8 hours and remove those bars that exceed the 9h threshold. Currently, it's not a huge problem, but I want to be able to stabilize it. Let's check Deep work versus Shallow work: </a> Last month I was discussing each item of the Deep work, but I will get back to discussing Shallow work only since it's what concerns me the most. Deep work is useful, sometimes it's not coding, but it's related and meaningful work. For shallow work, we have: Meeting time is stable (and productive), considering two 1-1 meetings (1 hour each) and four weekly meetings (around 40 minutes each)</li> Read/Reply Twist is stable but still consuming much time, more than 2 hours every day.</li> Lunch/Break is now complete! I'm spending around 26 hours in lunch/break. Considering that I had 19 days of work, it's less than 1.5 hours. I should stop and stretch more than I'm doing now.</li> </ul> Let's check the Twist usage by hour (previous month first, this month after): </a> </a> No significant changes, and as I said in my previous review, I'm not that satisfied with this chart. The perfect chart for me would have a small peak at 9-10, almost no usage between 10-13, a giant peak between 14 and 16 and less usage from 16 to 21. That performance is what would be more productive to me according to the daily when tracker</a>. Now, let's continue with my personal projects, last month first and this month last: </a> </a> What an improvement! It's probably related to my presentation since I'm rehearsing it a lot. 😅 Here is my data from RescueTime</a>: </a> </a> My pulse is worst this month. I'm still tracking my Telegram usage since it's the most used application of the Very distracting category. Here is the comparison from the previous month to the current one: </a> </a> It seems the usage increased. I don't know why yet. Comparing Telegram usage by time of the day, we have (last month first, this month second): </a> </a> It's not that used in my peak times, but it seems to be the opposite of Twist usage. I have to work on that. Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> </a> This month I have almost 8k steps compared to 7k from the previous month. 🎉 Let's check my weight: </a> It's nice, but it doesn't show what I want. If you look by the 90 days perspective using MyFitnessPal</a>, we have a better picture of that: </a> My plan to lose a little bit of weight is finally on the way. 👍 Here is my sleep data for this month: </a> Good to see it's improving every month. 🙃 TV Shows</h3> According to tvshowtime</a>, I watched just 1 episode this month: </a> It's probably related to the last episode of Sense 8. I forgot to get my data from trakt.tv</a> at the beginning of this month. The current version already includes some other TV shows. I will keep last month's version here for reference. [](/images/stats/2018/jun/tvshows-trakt.jpg ") The most important part is in blue: TV Shows: 31d 22h 50m</li> Movies: 10d 15h 22m</li> </ul> Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the number of words and errors when I'm writing. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. Here are my stats for this month: 47147 words written (38747 last month)</li> 595 corrections made (385 last month)</li> 10973 unique words (11213 last month)</li> </ul> It seems that I'm writing more but not with a better vocabulary 😞. I'm not sure if it's related to the fact that I'm not tracking everything I type in Twist</a> anymore. 🤔 Locations</h3> Let's compare the previous and this month, the previous first and this month right after it: </a> . </a> One new city popped out, and according to Google locations, it's São Paulo 🤔. A little bit more time in a vehicle. It seems that I'm getting out of the cavern more nowadays 😅 </a> . </a> Still many kilometers to "reach the moon": </a> Expenses</h3> It's time to check my expenses! 💰 This month I spend 29% of my earnings, which is still below my expectations (40%). This 29% are distributed into the following categories (in pt-BR): </a> I see more general expenses (Compras) than I would like. Gifts and donations ( Presentes / Doações) are quite high this month because of my parents in law health insurance. I decided to add it to the donations category because I'm already using the Family one (Família / Filhos) to track the expenses with my dog. 😅 We spent a lot with Doctors and medicines this month (Saúde), but I hope it will not be a recurrent expense. My total savings increased by 1.32% this month, and now I have 95.35% of my goal. Time to write this blog post</h3> It's an important metric to understand if it worth taking the time to write it. So: It took 3 hours and 40 minutes to write it It was a good time considering my average. 🎉 Conclusion</h3> It was quite hard to take the time to write down this post, but I'm glad I did it. I feel excellent when I read my accomplishments every month. ☺ See you next month. 🖖 Review of Fast Focus: A Quick-Start Guide To Mastering Your Attention, Ignoring Distractions, And Getting More Done In Less Time!

This book is short and full of great advices. Here are my raw notes about the book: Voluntary attention: when you're reading a book in the same room as your family is watching TV. It's like a muscle and can be trained.</li> Involuntary attention is when you see a notification on your phone that removes you from your focus.</li> Broader attention is when you check things in a bird's eye view. It provides a big picture of the situation</li> Focus attention is when you focus on a particular problem.</li> You use the broader attention to find what to focus and use focus attention to work on that particular issue</li> Both broad and focus attention are under your control</li> Lack of focus can be caused by lack of interest, negative emotions (stressed, annoyed, depressed, etc.), poor organization (how you plan your day), low energy levels (good food, enough sleep, regular exercise), lack of control. — remote working is excellent to help with this</li> Mind-wandering is not always bad; you have to make it work for you. Mind-wandering helps your creativity</li> Focus when you have to focus. When you're in the gym or showering, let your brain wander, and you may be surprised with the results</li> Mental fatigue is one of the factors that make it hard to Focus. Get sufficient sleep!</li> Stress erodes your attention</li> A cluttered mind is an unfocused mind. Our brains often come up with ideas to feel our minds.</li> Unresolved problems are bad for your focus (relationship, money problems, etc.)</li> Lack of a plan is bad for focus (remember the last time you went to the groceries store without a shipping list? No focus at all)</li> Your phone and social media are obviously bad for your focus. They are always fighting for your attention</li> When you have a good focus, you spend a better time with your loved ones, focusing on them.</li> Which kinds of sounds disrupt your concentration? Maybe the conversation is bad but classical music is not</li> Look for the smells that improve focus</li> Separate a zone for work and another for play. Cellphones, tablets, and other devices should not be part of the work zone.</li> According to scientists, a disorganized desk interferes with focus. Try to keep your desk as empty as possible</li> List the items you need to complete a task and keep them in reach. All other items should go to a box aside. You can organize it later.</li> Keep items you use every day in the first drawer and the ones you don't use much in the bottom drawer (invoices, etc.)</li> Limit the number of tasks to 5. A lot of tasks will erode your attention and makes you feel stressed. It's better to look for more tasks than postpone</li> Check your email only twice a day</li> Sardonic effect. uncompleted tasks take more attention than the completed ones</li> Know your why. It will help you focus and do a better work</li> Take short breaks and stretch or walk outside. Power naps are also powerful. These breaks actually increase your productivity instead of decreasing it because you tend to be more focused</li> Schedule time chunks so you can focus on the same kind of tasks for a period. Don't forget the breaks</li> Avoid scheduling meetings. If you have to schedule them, propose a stand-up meeting or a meeting with no food to make it uncomfortable. Meetings should be short and productive</li> Control your productivity. Talk to people who usually offend it and let them know about it and make them feel special. If someone comes to talk to you at your most productive time, then he/she that you can't talk now because you're concentrated to finish a task, but you will be available at X so you both can talk</li> Track your energy levels during the day for two weeks. Review your data and plan your days accordingly</li> Avoid your email</li> Try quick meditation to regain focus</li> Don't take more than 400mg of caffeine a day</li> </ul> Review of Managing Oneself Unknown — Sun, 01 Jul 2018 00:00:00 +0000 Book: Managing Oneself</a> by Peter F. Drucker. Rating: ⭐️⭐️⭐️⭐️. This book is not life-changing but it's small, straight to the point, and has many terrific bits of advice for your career and life. I would totally recommend you to read it since it's not expensive and quick to read/listen to (around 1 hour on Audible). Here are my raw notes about the book: Feedback analysis: whenever you take a crucial decision or action take note of the results you're expecting. After 8 or 9 months, compare the expected results with the actual results</li> People think ideas move mountains, but bulldozers move mountains, ideas show where the bulldozers should work</li> Manners are like oil for a machine; they reduce friction between two bodies</li> We have to know ourselves and place ourselves where we can make the most significant contribution</li> Feedback also shows you what not to do. There is a vast number of areas where we don't have the competence to even be mediocre. In this area, a person should not take a job or assignment. It takes much more effort and time to go from zero knowledge to mediocrity than from improving from first-grade performance to excellence</li> It's important to know how you perform, so you can adjust yourself to perform better</li> Are you a reader or a listener? That changes a lot.</li> How do you learn? Is it by copying? Writing? Speaking?</li> Some people are great as subordinates, but they may be terrible when it's time to take the decision</li> People in the first spot usually put people they trust in the second spot as their advisor. People who don't like to make decisions are generally outstanding in this position</li> When do you work best? Under stress or a calm environment? When working for big companies or small ones? Don't take jobs where you can perform your best</li> The mirror test: what kind of person do you want to see in the mirror in the morning? Choose what you wish for yourself</li> Values are the ultimate test. Make your values align with the company you're working for, or you will not be satisfied in the long term.</li> You should find what you should do, not just execute what is given. Doing what you want to do make you better in life</li> Understand relationships. Your co-workers are people like you, with strengths and weaknesses. You have to learn how your co-workers work. Example: do not write a report to your boss if he is a listener</li> Plan the second half of your life. Most knowledge workers get bored after working in the same sector for many years but they usually still have a lot of productive years ahead. Start a second career or participate/build a non-profit organization</li> </ul> Review of A Filosofia Explica as Grandes Questões da Humanidade Unknown — Tue, 26 Jun 2018 00:00:00 +0000 Book: A Filosofia Explica as Grandes Questões da Humanidade</a> by Clóvis de Barros Filho. Rating: ⭐️⭐️⭐️⭐️. Um livro bem interessante para aqueles que querem pensar sobre algumas coisas mais "profundas" mas sem precisar adentar em um idioma mais complicado. Os autores comentam de forma simples sobre algumas questões interessantes (e as vezes complicadas) da filosofia. Se você já conhece muitas delas mais a fundo, provavelmente esse não seja um livro para você. Caso você conheça pouco e está procurando um meio termo entre raso e profundo, esse provavelmente seja um bom livro. Esse livro porque ele me fez pensar sobre várias coisas interessantes e rever algumas coisas que eu venho lendo no momento. A forma que os autores expressam as ideias é as vezes boas e as vezes ruim, mas te faz dar risadas de vez em quando, dependendo do seu humor. Minha notas desse livro Muitas vezes as pessoas acreditam que se você é honesto, você será recompensado. Nada mais equivocado. A ação moral não é conectada com os acasos tristes do mundo. A atividade moral e a tristeza não tem nenhuma ação de causalidade.</li> A psicoterapia abre feridas para curá-las</li> A vida em sociedade supõe algumas concordâncias de valor</li> Toda vez que algo nos alegra, queremos mostrar aos outros porque isso também vai alegrá-los. Filósofos não são diferentes, se alegram com a filosofia e estão convencidos que todos deveriam se alegrar também.</li> Só seríamos livres quando pudéssemos agir na contramão de nossos desejos. Seríamos livres quando decidíssemos fazer o que não queremos</li> O desejo é algo que o corpo impõe. Se você vive para satisfazer o desejo você não é livre, se torna um escravo do desejo</li> A liberdade é a vitória da ideia e da razão sobre os apetites das entranhas. Essa é a ideia apresentada pelos filósofos idealistas</li> Propõe se que a ética seja uma teoria da moral</li> A ética tem como matéria prima a moral</li> Ética e moral não são a mesma coisa mas tem tudo a ver</li> Discípulos de Platão acreditam no valor absoluto: existe só um tipo de música boa (que tem sua verdade no mundo das ideias). Outros podem acreditar que a verdade depende de cada um e de sua moral.</li> Se amassemos mais, careceríamos menos de moral</li> O amor é escasso e o ódio abundante</li> A generosidade é uma virtude da moral. Na falta de amor, você pode ser generoso.</li> Uma mãe amamenta um filho por amor. Se ela não ama o filho e ainda assim amamenta, faz por generosidade, por achar que isso é um dever.</li> A moral é a imitação racional de um sentimento que garante boas condutas</li> Se amassemos mais, muito mais, e amassemos todo mundo, a moral seria inútil.</li> Os animais são o que são, não possuem moral. Moral é uma coisa humana.</li> Você só é livre quando faz o que não quer, sendo assim, não é escravo do desejo</li> Ser sucumbir aos desejos é ser escravo de você mesmo, mas resistir a todos os desejos é tirar as coisas "coloridas" da vida</li> Quando você errar a resposta de um problema matemático, comemore, pois esse é o resultado da sua liberdade de escolher como chegar a um resultado</li> O sabiá não é livre para voar, ele é escravo do voo. Ele depende disso para viver. Não pode simplesmente decidir andar a pé por aí.</li> Uma pessoa tende a votar em candidatos de esquerda dependendo de quanto mais capital cultural e menos capital econômico. O oposto acontece para cara votos em candidatos de direita.</li> Homens não vivem por instinto, como animais, e eles precisam compensar essa pobreza instintiva com inteligência</li> A origem da desigualdade dos homens: Russeau</li> Quando falamos sobre o que o mundo produziu em nós, já há outro mundo e outro nós</li> Na frase "eu te amo" a pessoa ama o que? Mãos? Voz? Glúteos? E quando isso mudar?</li> Se tudo que falamos tem origem na sociedade i não é algo exclusivo nosso, a nossa definição própria também segue o mesmo princípio.</li> A sociedade dá os ovos mas controla como fazer o omelete. O que você fala é fruto da sociedade, mas você não pode só falar bem de você e isso não muda o que a sociedade pensa sobre você.</li> Quem tem o poder tende a achar formas de se distinguir das outras pessoas (cora do rei, roupa de grife do empresário, etc) e estigmatiza como inferior as coisas que são diferentes, como dizer que gostar de música clássica é bom e gostar de funk demonstra ignorância e mau gosto.</li> Há também a necessidade de desqualificar coisas que tentam se qualificar como parte do grupo, como falsificação de produtos, que é uma tentativa grotesca de se parecer o que não é.</li> A república de Platão</li> Platão não era a favor da democracia pois dizia que pessoas pouco inteligentes não deveriam guiar o futuro de uma nação/cidade</li> Postar somente seus momentos felizes em redes sociais também é uma arma de dominação e poder</li> "Fiz uma viagem, que eu mesmo planejei. Tudo foi ótimo" é outra forma de dominação</li> Fazer o outro crer que você é melhor ou mais digno que ele</li> Esse é o mesmo sentimento de quando estamos com uma pessoa famosa e tentamos parecer menos bobos ao lado dela por causa da ideia que ele é melhor do que você. Isso é poder.</li> Maquiavel percebeu o uso do poder para controle e seu nome virou sinônimo de ser ardiloso e usar o poder para manipular as pessoas</li> Espinoza dizia que todas as religiões são instituições políticas e como tais, servem apenas para legitimar uma forma de dominação. Os textos são datados de uma época específica e feitos para um povo específico por um líder específico para sua dominação. Deus não tem nada a ver com eles, os homens é que tem.</li> Para Maquiavel, a política é a continuação da guerra por outros meios</li> "Uma economista disse que é aceitável e em alguns casos até recomendado, ter de 5 a 10% de taxa de desemprego em uma economia em desenvolvimento. É fácil dizer isso empregado, quero ver o que os desempregados dizem."</li> As regras morais que se aplicam para o homem comum não se aplicam para o soberano no exercício do poder, segundo Maquiavel. Isso acontece porque para um homem comum, as consequências de suas ações afetam somente a ele e para um soberano, afeta muitas pessoas</li> Porque você não senta na cadeira do professor quando entra em uma sala de aula? Porque você já foi alunizado. Sabe o que é ser um aluno e parte disso é o respeito ao professor. O professor tem poder por causa desse método. Saber e poder, não há um sem outro.</li> Ter bom gosto é gostar do que todo mundo gosta e se alinhar com o padrão de estética dominante</li> Se atente as regras do jogo: quando definidos os padrões de estética, haverão os dominantes e os dominados, os de bom gosto e os de péssimo gosto, os in e os out.</li> Quando um objeto diz quem é dominante ou dominado, esse objetivo se torna alvo de certas restrições.

Rating: ⭐️⭐️⭐️⭐️. It's a good book overall, especially if you are (or want to be) a CEO. Some (many?) ideas are not aligned with the way I would manage my own company, but there are many useful insights into hairy situations one may be faced during his CEO time. Sometimes the author contradicts himself, IMO. The difference between wartime and peacetime seems like being a jerk and being someone I would follow. The description of good and bad product managers was the best part of the book, IMO. I saw some product managers failing miserably in the course of my career, and it was exactly what he described. Here are my notes for this book. I added some personal comment after double dashes: The hard thing about hard things is that we don't have the formula to solve them</li> Don't attach yourself to first impressions. People are usually more than they look</li> The best thing about startups is that you only feel two kinds of emotions: euphoria and terror</li> You need two types of friends: one that will be very happy for you when you succeed. Truly excited as if it was happening to him. The second one is a friend who you can call if things go terribly wrong</li> "I was so absorbed into work that I forgot what really matters". — his wife stopped breathing because of wrong medicines and almost died. He knew that 1 day after it happened</li> If you are going to eat shit, don't nibble</li> "I will not receive a recommendation from people who don't know the whole picture" about the employees who made a presentation against the "new project". "Did I asked for this presentation?"</li> Sloppiness will not be tolerated</li> It's good to ask yourself: Why am I not doing it?</li> Startup CEOs should not play the odds.</li> "I don't believe in statistics, I believe in calculus" — 💭 pfff</li> The first principle of the Bushido: keep death in mind — 💭 It's also somehow related to Stoicism</li> When your dreams start to become a nightmare, you find yourself in 'the struggle". The struggle is when you ask why you started this when people ask why you don't quit when you believe you shouldn't be the CEO of your company when you go on vacation to feel better and feel worse</li> Share the burden whenever you can. Noone will feel it weightier than you, that are responsible</li> Let people know the problems of the company so they can fix them. It doesn't matter how good is your team, they can't solve a problem they don't know about. Let the information flow in both ways inside the company.f</li> Layoff correctly. Admit your fault for the layoff. Don't try to use it as an excuse, saying that you can use it for the better. Show them (lay-off employees) you care.</li> How do I win with such misfortunes? Nobody cares, just run your company</li> Mark's opinion: doesn't look like a head of sales, went to a weak school. — 💭 LOL</li> He wasn't an easy cultural fit, but he is a genius. — 💭 LOLOL</li> Take care of people first — 💭 dafuq, he just said that he hired a guy who wasn't a cultural fit and his team was not very comfortable with the guy. "In war times, I need a general"</li> Why people usually leave: because they hate their manager or because they were not learning anything</li> Good project managers know the market, the product, the product line, and the competition extremely well, and operate with a strong balance of knowledge and competence. A good product manager is the CEO of the product. Good product managers take full responsibility. They measure themselves by the success of the product. A good product manager knows the context going in and takes responsibility for implementing a winning plan.</li> Bad product managers have lots of excuses: Not enough funding, the engineering manager is an idiot, I'm overworked, Microsoft has more engineers working on it. I don't have enough direction. A CEO doesn't make that kind of excuses and neither should a CEO of a product.</li> Good product managers are not part of the product team, they manage the product team.</li> Engineering teams don't consider the product manager as part of the marketing team. Good product managers are the marketing counterpart of the engineering manager.</li> Good product managers define the what instead of the how of a product.</li> Good product managers don't give informal directions, they write FAQs, white papers, and other documents that can be used by the sales team.</li> Bad product managers voice their ideas loudly but say that "powers that be won't let it happen". Once bad product managers fail, they point out that they predicted it would fail.</li> Good product managers focus the team on revenue and customers. Bad product managers focus the team on how many features the competitors are building.</li> Good product managers send their status report on time because they are well organized. Bad product managers forget to send their status reports because they don't value discipline.</li> To hire an employee from a friend's company, always ask the candidate to talk to your friend first. If the candidate doesn't feel comfortable with that, end the process.</li> Schedule meetings where the new executive can ask as many questions as he needs. If he doesn't have any questions in the first few days, consider firing him.</li> Management debt: Don't overcompensate employees because they have a better offer. Other people will find out that the best way to get a raise is by getting an offer</li> Bad feedback generates crappy performance</li> Do your employees believe in the mission of the company?</li> Minimize politics</li> Hire people with the right kind of ambition. The ones who want the company to grow and grow with it. Avoid people who only consider his/her personal success</li> After any promotion, everyone in that sector will judge if it was by merit or politics. Depending on that judgment, they may feel undervalued, go against the promoted person, or try to copy the political behavior. You must have a formal, visible, and defendable process of promotion to avoid this behavior on the other employees.</li> Hire people who describe themselves as part of a team, more we than I.</li> The Peter principle: someone will be promoted until it's competent for the role. This person will stay in the role he is not competent for.</li> The law of crappy people: people on other levels will benchmark themselves to the crappiest people in the next level, so they can demand a promotion as soon as they reach that level</li> When defining levels of careers for promotions, be very specific about the competencies. Avoid terms like: "Should be very competent in business". If possible, use the names of great people of the market as benchmarks.</li> Why hire senior people: you buy time for your company, and time is an important resource for startups.</li> Think about your needs. Do you need internal knowledge or external knowledge? Sometimes it worth promoting an employee who has a lot of knowledge on your codebase for a role that needs it</li> 1-1 are employees meeting, not managers meeting</li> The only thing that prepares you to run a company is running a company</li> The difference between a hero and a coward is just what they do. The hero is more disciplined, and he does what he has to do, but both feel the same.</li> Wartime CEO is the one you don't want to work with. Basically, he is a workaholic stressed guy (because of pressing times and the chance of a broken company)</li> Peacetime CEO works to have a more creative environment and grow with new ideas.</li> Sometimes you need to go to war</li> If you want to fire someone, fire this person. Do not prepare her to get fired, prepare her to succeed. — 💭 This seems to be a piece of advice that aligns with Radical Candor</li> If you have negative feedback, just say it and suggest improvements. Don't try to start with "It's good but..." — 💭 another Radical Candor reference</li> Accountability versus creativity paradox.</li> Assume people have good intentions until proved otherwise</li> Accountability for effort. If people are not giving enough effort, this needs to be checked</li> Accountability for promises. Make a commitment keep a commitment. You have to weight accountability for promises: a promise to send an email is different from a promise to solve a harder computer science problem</li> Take the right risks and hold employees accountable to the risks they take.</li> When the company starts to become a candidate for acquisition, it's important to pay the CEO a market salary</li> </ul> It's a book worth reading. Extract the good parts and ignore what doesn't match your managing style. Review of Blood, Sweat, and Pixels: The Triumphant, Turbulent Stories Behind How Video Games Are Made Unknown — Mon, 11 Jun 2018 00:00:00 +0000 Book: Blood, Sweat, and Pixels: The Triumphant, Turbulent Stories Behind How Video Games Are Made</a> by Jason Schreier. Rating: ⭐️⭐️⭐️⭐️. Good book overall, I did not take notes because it seems like a fictional book. :P If you like this book I would also recommend you to read Masters of Doom</a> and some chapters of Hackers: Heroes of the Computer Revolution</a> where they tell some game companies stories. I would also add Indie game: the movie</a> (also available on Netflix) to the list of complimentary content. I was already aware of what would be like to work for a gaming company, but this book also adds some horror stories I was not expecting. The total lack of decent management in Halo Wars is something unbelievable for those working with software in big companies. The whole story of indie developers was also lovely to see. For some, it's insane to see the number of hours these developers have to work to get the game they want. I usually focus on the result, when the story reaches the end I feel like it worth the work. I published one small game demo called Skeleton Jigsaw</a>, it took 8 months of my spare time, but I regret nothing. :) My conclusion about this book: you should definitely read it if you want to work with games. You should also read it if you like games in general, the author explains all the technical terms (which was a little bit boring for me). Stats for May, 2018 Unknown — Fri, 08 Jun 2018 00:00:00 +0000 It's May, and it's time for metrics! 📊 Books</h3> Two books read this month, but both received a 3 stars review: </a> Wait, What?: And Life's Other Essential Questions</a>: Exactly what the author says in the beginning: It's a lecture that became a book. Not bad, but OK-ish.</li> Shop Class as Soulcraft: An Inquiry into the Value of Work</a>: More political views than I was expecting and the pacing is not so good. The motorcycles part resonates with me a lot.</li> </ul> Note: I write a full review for each book I read. You can find them on my Goodreads account</a>. Articles</h3> I'm experimenting with an integration between Pocket and Google Spreadsheets via IFTTT</a>. The idea is not to use Javascript codes anymore, but it's still ongoing. I'm adding a tag to the articles I read and want to include in my list of articles read for the month. For this month, I'm using the tag 201805</code>: </a> I use a SUMIF</code> to sum all lines containing the string 201805</code>, and got 26 articles read. I did not start at the beginning of the month, and it should be considered just an experiment for now. I hope to soon change to this method of collecting data about the articles read. Meanwhile, it's worth keeping the old method: var pocket = {"unread":1501,"unread_pct":3.66,"read":1096,"read_pct":4.2} var uls=document.body.getElementsByTagName("ul"); unread = uls[0].children.length; pocket["unread_pct"] = +((1 - pocket["unread"] / unread) * 100).toFixed(2); pocket["unread"] = unread; read = uls[1].children.length; pocket["read_pct"] = +((1 - pocket["read"] / read) * 100).toFixed(2); pocket["read"] = uls[1].children.length; console.log("# Result: " + JSON.stringify(pocket)) # Result: {"unread":1539,"unread_pct":2.47,"read":1146,"read_pct":4.36}</code></pre> It means I have 1539 articles unread and 1146 articles read. Comparing with my results from the last month (1501 unread and 1096 read), I got around 2.47% more unread articles and 4.36% more read articles. Still adding more than reading (😕), but I'm still not sure if this is a problem. I may never read all those articles I marked to read later, but does it really matter? 🤔 Coding</h3> Here are the charts from Wakatime</a> since the last post. I will start with editors this time: </a> Nothing new here, 70-30 between Vim and Emacs. </a> Not that bad. </a> Markdown is back as the first language because of some big posts I had to write using Emacs. Python is the second most used language because of Todoist</a> and Twist</a>, and Ruby is still present there 😉. This month I had a little bit of Rust and Go, which is nice. I think I will have more Rust next month. 😀 Speaking</h3> No talks this month as well 😕, but one scheduled for the next month. 👍 Completed tasks</h3> Here is the comparison of the tasks for the last month (first) and the tasks for this month (second). I extracted it from Todoist</a>. </a> </a> Things are better this month! Hope to remember to take the screenshot before the week cycle ends next month. Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 2 days and 18 hours of podcast time. Here is the list of Podcasts and their times: </a> Unfortunately, this list is based on time. Anticast</code> is not a Podcast I'm used to listening, but they have some good episodes from time to time. The problem is that they are quite long (~1h30) while other shows tend to have episodes of about 30min. Well, keep in mind that this is an "all-time list", and I'm tracking time instead of the episode which makes short podcasts not to appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a> comparing the last month (first) and this month (second): </a> </a> I had 21 work days tracked this month, and I worked for 173 hours, which mean that I worked 5 hours more than I should (the same as I had in April). Not bad but the goal is to reach 8 hours and remove those bars that exceed the 9h threshold. Let's check Deep work versus Shallow work: </a> I decided to track my lunch/break time, so I can understand how much time I'm spending on tasks that are not related to work at all (reading emails, talking to people via Telegram, etc.). Unfortunately, I started this too late. I have only 10 hours of lunch break so we will have to skip it to the next month. I have to be more descriptive with Deep work. I'm trying to keep Writing and Read/Reply Twist as the same thing, maybe it will be better next month. I'm also stunned by the small number tracked as deep work coding. This month I spent far more time discussing and writing things down than actually coding. 😕 For shallow work, we have: Meeting time is stable (and productive), considering two 1-1 meetings (1 hour each) and four weekly meetings (around 40 minutes each)</li> Read/Reply Twist is still consuming a lot of time, more than 2 hours every day.</li> Lunch/Break is still work in progress</li> </ul> Now that I'm looking into all the data, I found it interesting that 1/3 of my time is spent communicating. 🤔 Let's check the Twist usage by hour (previous month first, this month after): </a> </a> I'm not that satisfied with this chart. The perfect chart for me would have a small peak at 9-10, almost no usage between 10-13, a giant peak between 14 and 16 and less usage from 16 to 21. I should have no usage after 21. The usage I described above is precisely the opposite of what is my productive time. I used the daily when tracker</a> and found the times I'm more alert and energetic. As usual, I should post about it as well but never do. 😕 Now, let's continue to my personal projects, last month first and this month last: </a> </a> It's definitely better! We should consider the holiday for this month, though. 😛 Here is my data from RescueTime</a>: </a> </a> My productivity pulse is better this month. Last month</a> I did some research on what happened and found that Magic the Gathering was taking a lot of my time and also adding some outliers, it seems to be better now. I'm still following my Telegram usage, here is the comparison from the previous month to the current one: </a> </a> It seems to be better but not much. I have an alert of my time spent using Telegram, but when it fires, it's usually too late. Working on it. Comparing Telegram usage by time of the day, we have (last month first, this month second): </a> </a> It improved a little bit during my peak times. I will consider that as an improvement and keep working on it. Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> </a> This month I have 7k steps compared to 8k from the previous month. I'm back to the gym, but my weight is still the same. I hope to have a big improvement next month: </a> Here is my sleep data for this month: </a> Better sleeping! That's good news! 🙃 TV Shows</h3> According to tvshowtime</a> I watched 8 episode this month: </a> These episodes are related to the new season of 13 reasons why and The End of the F***ing world. I mentioned that I'm trying trakt.tv</a>, and I'm still getting used to it. This is what I'm going to use: </a> As you can see, I can also track movies. The only data that matters is the following: </a> I know I'm still missing some movies and TV shows there, hope to add them as soon as I remember. Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the number of words and errors when I'm writing. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. Here are my stats for this month: 38747 words written (61385 last month)</li> 385 corrections made (934 last month)</li> 11213 unique words (16473 last month)</li> </ul> Grammarly is not working good inside Twist anymore, I don't know why. I will have to reach out to Grammarly again soon. Locations</h3> I've added some places to the list: </a> Other than that, no new cities or countries. 😞 Let's compare the previous and this month, the previous first and this month right after it: </a> . </a> One new city popped out, but I have no idea which one it is. Maybe it is the lost city from the last report. 🤷‍♂ My time commuting improved a lot this month: </a> . </a> Still many kilometers to "reach the moon": </a> Expenses</h3> It's time to check my expenses! 💰 This month I spend 32% of my earnings, which is still below my expectations (40%). This 32 % are distributed into the following categories (in pt-BR): </a> We spent more with Mercado (groceries) than expected (last month it was just 3%), hope to adjust it for the next month. As usual, I'm not considering the money in transit from my company to my personal account (waiting for money exchange, taxes, accountant payment, etc.). So, without considering it, my total savings increased by 0.06%. This is a good number given the current scenario of the Brazilian economy (it's positive because I added money, or it would be negative), and now I have 94.11% of my goal. Time to write this blog post</h3> It's an important metric to understand if it worth taking the time to write it. So: It took 5 hours and 12 minutes to write it It's much more than I expected, but I think it's happening because I was researching different services and also doing some research on how to conduct my investments. Hope to decrease this time next month. Conclusion</h3> It took a lot of time to write this post, and this is bad, but other than that, the month was good in general. All my goals for this month were met, so I have nothing to complain. ✌ See you next month. 🖖 Review of Zero to One: Notes on Startups, or How to Build the Future Unknown — Fri, 08 Jun 2018 00:00:00 +0000 Book: Zero to One: Notes on Startups, or How to Build the Future</a> by Peter Thiel. Rating: ⭐️⭐️⭐️⭐️. It's a good book. There are some good insights, some things that only work for a particular context, and some others that I disagree. I have to highlight one item of my notes: "Even working remotely should be avoided because misalignment can creep in whenever colleagues aren't together full-time, in the same place, every day" That made me laugh out loud in the street while listening to this book. I'm working remotely for almost two years now. In the past 1 year, I was more aligned than ever with the company ideas. I truly think the author doesn't have enough experience with remote-first companies to say something like that. As I said, some parts of this book only work in the author's context. Other than that, it's a book worth reading. The author has a lot of experience with startups and a successful career. The questions he mentions (available in my notes) are one of the best parts of the book, and you can try to apply them to most of the companies you know. Here are my notes: What is one truth that very few people agree with you? (There is no God is a popular answer)</li> Horizontal progress is when you have a typewriter and you build many</li> Vertical progress is when you have a typewriter and build a processor</li> Silicon Valey learned four lessons from the bubble: 1. Small incremental steps - 2. Stay lean and flexible (don't plan too hard) - 3. Improve the competition - 4. Focus on product, not sales. If you need sales to sell your product, it's because it's not good enough</li> But the opposite principles were yet probably more correct</li> It's better to risk boldly than trivial</li> Bad plan is better than no plan</li> Competitive market destroy profits</li> Sales matters just as much as the product</li> To create the new generation of companies we have to reject the dogmas created in the past</li> If you want to create and capture value, don't build an undifferentiated commodities business</li> Google is a tech company, which helps to remove all kinds of undesired attention from monopoly laws</li> All failing companies are the same, they fail to escape competition</li> Find a new market and grow. It's hard to get 1% of a crowded market. Even if you get it, the competition will be really high, making it hard to grow</li> Don't disrupt, avoid competition as much as possible. Disruptors are people who look for trouble and find it</li> Dominate a small niche and scale from there</li> Sucess is half luck, half good timing, and the rest brains (Jeff Bezos)</li> Statistics doesn't work when the sample size is one</li> You are not a lottery ticket. It's more than just luck.</li> Research about the power law</li> The road doesn't have to be hidden after all. Take the hidden path.</li> A startup messed up in its foundation cannot be fixed</li> It's very hard to go from zero to one without a team</li> Everyone on your team must be available full time. Anyone who doesn't own stock options or draws a regular salary is fundamentally misaligned. They are trying to get money in the near turn not to grow the company in the long future. That's why hiring consultancy or having part-time employees doesn't work.</li> Hiring is a core of any company and should not be outsourced</li> Software is not meant to replace humans but to be a tool to improve their performance.</li> Clean tech failed because they neglected one or more of the seven questions that most business must answer.</li> Question 1. The engineering question- can you create breakthrough technology instead of incremental improvements?</li> Question 2. The timing question- is now the right time to start your particular business?</li> Question 3. The monopoly question- are you starting with a big share of a small marketing?</li> Question 4. The people question- Do you have the right team?</li> Question 5. The distribution question - Do you have a way to not just create but deliver your product?</li> Question 6. The durability question - will your marketing position be defensible 10 or 20 years into the future</li> Question 7. The secret question - Have you identify the unique opportunity that others don't see?</li> The engineering question: Your product has to be 10x better than its competitors. Just 20% better will not be enough to justify the change/risk for many users</li> The biggest threat to a founder is to become so self-confident of his mith that he loses his mind We cannot take for granted that the future will be better, so we have to work to create it today</li> </ul> Review of Wait, What?: And Life's Other Essential Questions Unknown — Fri, 25 May 2018 00:00:00 +0000 Book: Wait, What?: And Life's Other Essential Questions</a> by James E. Ryan. Rating: ⭐️⭐️⭐️. I bought this book as an Audible daily deal. For the price and size of the book, it was ok. The book is exactly what the author says in the beginning: It's a lecture that became a book. It can be summarized in less than 10 lines. Please read the other reviews and you will know the whole book. These are my notes while reading: Questions are just as important as answers. An answer is just as good as a question is.</li> The only bad questions are not questions at all; they are more like insults being used as questions</li> "Wait, what?" is a question for clarification.</li> Asking "Wait, What?" helps you to pause and think before reaching a conclusion</li> Understand first and make judgment last</li> If you ask "I wonder why..." About the present, you may want to ask "I wonder if.. " about the future</li> "Couldn't we at least..." Can be used to get out of a stuck state</li> "How can I help?" can save lives. It can help you to understand what the real problem is.</li> "What truly matters?" should be used to gain focus on any situation</li> </ul> Review of Shop Class as Soulcraft: An Inquiry Into the Value of Work Unknown — Thu, 17 May 2018 00:00:00 +0000 Book: Shop Class as Soulcraft: An Inquiry Into the Value of Work</a> by Matthew B. Crawford. Rating: ⭐️⭐️⭐️. I was between 3 and 4 stars for this review but decided to stick with 3. The book has some interesting insights and the whole motorcycle thing resonates a lot with me, but in general, I found myself bored by the pacing and abstraction. Here are my raw notes about the book: Things have a hood under the hood nowadays (cars). When you open the hood, you don't see that many of the parts anymore</li> Economists would argue about taking the time to make what can be bought</li> "I feel proud when I take my wife to a local restaurant and we receive special treatment" because he restored the Cook's bike</li> "It feels good when I go to the local riders meeting and some of them are using my shop's T-shirt</li> Many jobs are being offshored.

Here is the script with the actual data: var pocket = {"unread":1446,"unread_pct":1.8,"read":1050,"read_pct":2.86} var uls=document.body.getElementsByTagName("ul"); unread = uls[0].children.length; pocket["unread_pct"] = +((1 - pocket["unread"] / unread) * 100).toFixed(2); pocket["unread"] = unread; read = uls[1].children.length; pocket["read_pct"] = +((1 - pocket["read"] / read) * 100).toFixed(2); pocket["read"] = uls[1].children.length; console.log("# Result: " + JSON.stringify(pocket)) # Result: {"unread":1501,"unread_pct":3.66,"read":1096,"read_pct":4.2}</code></pre> It means I have 1501 articles unread and 1096 articles read. Comparing with my results from the last month (1446 unread and 1050 read), I got around 3.6% more unread articles and 4.2% more read articles. Well, I'm reading more than adding, but I don't know if I'm happy with this situation. It's been some months since I'm complaining about my read it later but it doesn't seem like a big problem. I'm experimenting with an integration between Pocket + Google Sheets via IFTTT</a>. The idea is to count the number of articles read and maybe we will have something new next month. Coding</h3> Here are the charts from Wakatime</a> since the last post. I will start with editors this time: </a> Nothing new here, 70-30 between Vim and Emacs. </a> I had some national holidays + days off this month. Also, I had some non-coding tasks (mostly writing) and it obviously impacted my hours of coding. </a> Python</code>, Markdown</code>, and Ruby</code> are the most used languages, as usual. Unfortunately, there's no mention of Rust</code> or Elixir</code> this month, but at least I have a small percentage of Golang</code>. Speaking</h3> Again, no speaking this month. I was thinking about it, and I think it is a hangover from the 21 presentations from last year. Completed tasks</h3> Here is the comparison of the tasks for the last month (first) and the tasks for this month (second). I extracted it from Todoist</a>. </a> </a> Things are back to normal, I guess. 🙃 Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 3 days and 6 hours of podcast time. It seems that 3 days is becoming average for me. As usual, here is the list of Podcasts and their times: </a> Remember that this is an "all-time list", and I'm tracking time instead of the episode which makes short podcasts not to appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a> comparing the last month (first) and this month (second): </a> </a> I had 19 work days tracked this month, and I worked for 157 hours, which mean that I worked 5 hours more than I should (it was 11 in the last month, so it's improving! 😀). Let's check Deep work versus Shallow work: </a> What I can take from this chart: Meetings are stable (and productive), considering two 1-1 meetings (1 hour each) and four weekly meetings (around 40 minutes each)</li> The Shallow work task (the most generic I have) is still the big black box. I mentioned to split the lunch time (lunch and break) but forgot to do that last month. Maybe I will start doing it this month (from April 15th).</li> </ul> "Read/Reply Twist" is still consuming a lot of time, more than 2 hours every day. Let's break Twist usage down by hour: </a> It seems that my strategy of reading Twist in the morning is working, but it's not fixing the problem of keep looking to it throughout the day. I should probably just skim it in the morning and get back to it at the end of the day. Still trying to improve this process though. Now, let's continue to my personal projects, last month first and this month last: </a> </a> Again, that's not much to compare here, but at least it seems stable. 👍 Here is my data from RescueTime</a>: </a> </a> It's worst than February and March 😞. I had a pulse of 62 on February and 54 on March, and it's now 43. It concerns to see that, so I decided what was causing such different. When looking at the chart for the entertaining category, I saw this: </a> It seems that my new (and old, at the same time) hobby Magic the Gathering is taking a lot of my spare time. I let rescuetime track all my time, not just working hours, and all MTG websites are considered as very distracting. Maybe I should configure rescuetime to monitor only "working hours", but I'm not sure what time should I use. 🤔 Still following my Telegram usage, here is the comparison from the previous month to the current one: </a> </a> It's still too high for me. I have an alert of my time spent using Telegram. The goal is not to receive this alert, but I'm currently failing at it. I have to improve this. I'm still trying to understand if I have a particular moment where I use Telegram the most, here is the difference from the last month to the current one: </a> </a> Hm, Telegram usage is spread throughout the day, that's not a good thing. I have to keep working on it. Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> </a> This month I have 8k steps compared to 10.5k from the previous month. This change is expected since I had two weeks to move around because of the retreat and my vacation in Santiago last month. I was expecting a big change in my weight, but it was not that bad. I'm expecting an increase next month though 😅: </a> Here is my sleep data for this month: </a> Not that bad, the same as March. Hope to improve it in May. 👍 TV Shows</h3> According to tvshowtime</a> I watched 8 episode this month: </a> We finished The punisher this month. Now looking for a new TV show to watch. I'm starting to try trakt.tv</a>, so I can try the movies I watch along with the TV shows. Unfortunately, tvshowtime only tracks TV shows. Maybe we will have some new charts next month. 😉 Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the number of words and errors when I'm writing. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. Here are my stats for this month: 61385 words written ( 50348 last month)</li> 934 corrections made (825 last month)</li> 16473 unique words (10944 last month)</li> </ul> It's expected to have a better value since last month had almost two weeks off because of Doist retreat + vacations. Nothing outstanding though. Locations</h3> I've added some places to the list: </a> Went to two different cities this month, one of them is 450km+ from my hometown. ✌ Let's compare the difference between last month and this month. Last month first and this month right after it: </a> . </a> And again, One new country according to Google. It's quite unstable to rely on their country count, but I think they got it right now. The number of cities did not increase for some reason. 🤷‍♂ As expected the amount of time commuting increased a lot this month (due to the travel I mentioned above): </a> . </a> Still many kilometers to "reach the moon": </a> Expenses</h3> It's time to check my expenses! 💰 My earnings this month were different from what I usually receive. All of this thanks to the profit sharing I receive from my previous employer. Considering that, I spent only 17% of the money earned this month. From this 17%, we have the following percentages: </a> I was expecting much more from Viagem (traveling, the orange piece), but it's good enough. Transport is the biggest one, but part of it will probably be reimbursed, as it's my wife's work expenses. With that said, Moradia (housing?) is my most significant expense. As usual, I'm not considering the money in transit from my company to my personal account (waiting for money exchange, taxes, accountant payment, etc.). So, without considering it, and keeping in mind that Easynvest (one of my brokers) has a crappy system that doesn't work, making me waste my time trying to retrieve the latest information about my investments, my total savings increased by almost 4% (!!) and now I have 94.06% of my goal. Time to write this blog post</h3> Some people are asking me about how much time it takes to collect all the data and write the blog post, so I decided to add this metric It took 3 hours and 31 minutes It is quite stable since I spent 3 hours and 30 minutes last month. That number considers the whole process of organizing my data (I usually review my investment portfolio as well), taking screenshots, and writing this post. Conclusion</h3> It was a standard month. Some outliers were found because of my Magic The Gathering hobby and 20+ hours commuting because of my travels is not that common, but other than that, everything is just fine. See you next month. 🖖 Review of A Guide to the Good Life: The Ancient Art of Stoic Joy Unknown — Wed, 18 Apr 2018 00:00:00 +0000 Book: A Guide to the Good Life: The Ancient Art of Stoic Joy</a> by William B. Irvine. Rating: ⭐️⭐️⭐️⭐️⭐️. Great book if you're curious about stoicism and its practices. After reading this I found that I'm practicing many techniques of stoicism for many years without knowing it. The book starts with the history of stoicism, the first stoics, and the context of their time. The beginning is not pragmatic as I was expecting but when I finished the book, I decided it was a good thing. After that the author explores the main ideas of stoicism one by one, using many references from important stoics of the past, and adding his own techniques and ideas. In the end, he mentions all his references and recommends further reading. It's a solid book, IMO. Here are my raw notes about the book: What is your ultimate goal in life? Think about it so you can plan and avoid life distractions to reach it</li> Stoics do not eliminate the feelings, just the bad feelings</li> Whatever philosophy of life one chooses, he will probably live a better life than using no philosophy at all</li> Zeno was the first stoic</li> The students of Zeno were known as Zenoians but they as Zeno gave his lectures at the Stoa Poikile, they became known as stoics</li> Zeno's students could detect the fallacies committed and then win the argument with logic</li> Virtue is based on one's excellence as a human being. How well he develops what humans were designed to do</li> According to Zeno, we were designed to be reasonable</li> How do we convince ourselves we want the things we already have? (Just like the Buddha discourse about desire)</li> Negative visualization. When you visualize losing something. We should live every day as it is the last day in a sense that makes us be more loveable and enjoy things and people. #Stoicism</li> Hedonic adaption. What makes us adapt to what we have and don't give much value to it</li> You should live today as it was the last day. You should not change your activities but your mindset regarding today.</li> When you don't realize you have everything you once dreamed of, you start being satisfied with life instead of always looking for satisfaction (and never reaching it)</li> Practicing Negative visualization prepares you for the changes in the world you live</li> A father who practicing negative visualization with losing their children will feel grief but not guilty if the child dies. Fathers who not practice will always think about the things they should have done with the child #Parenting</li> If you consider something to be the last time you're doing it, it will become an extraordinary event. It's like the last meal in a restaurant about to close forever or the last kiss with a lover moving to a different part of the globe indefinitely (side note: it's also referenced in "When: The Scientific Secrets of Perfect Timing")</li> The trichotomy of control. Things we have complete control, things we have some control, and things we have no control.</li> We have complete control over how to set our values and goals.</li> We have some control on how to complete our goals and live by our values, but it doesn't depend on us only.</li> We have no control if the sun will rise tomorrow. You should not spend time or energy on it because it will not change the outcome.</li> You should internalize goals you don't have complete control of. Instead of setting a goal to win a tennis match, you should set a goal to do your best in training and during the match.</li> Be fatalistic about the past, you can't change it and should not spend time and energy thinking about "what ifs". Learn from it and let it go</li> Seneca recommends to sometimes live as if something bad happened. Instead of just thinking about how it would be if you lose your wealth, your should practice poverty once in a while.</li> In many cases, we work hard to acquire something we think we would be miserable without it. The truth is that you can live well without it but you will never you without actually experiencing it</li> Embrace discomfort so you can enjoy the comfort and be prepared for when bad things happen</li> When you're ready to feel discomfort, you will not feel anxious if the future may bring bad things for you because you are ready for it</li> If we don't practice self-control we end up being a slave of what the life offers and get away from completing our goals</li> Be selective with those you choose to be your Friends. Time spent with dirty people tends to make you dirty as well</li> In social interactions avoid people who talk about gambling, drinking, and other people. If you find yourself in such a situation, change the subject of the conversation because these subjects don't help you with anything</li> Auto-control should also be exercised regarding sex. Especially for young people who may have a big change in their lives if they can't control sex and have babies. That may be in a way of their dreams and accomplishments.</li> To help with sex desire, try to see the relative other as pieces, not a whole. Think about him/her as a set of lungs, arms, tears, etc</li> Insults from random people should be considered as the bark of a dog. We may add a note that that dog doesn't like us, but should not be upset thinking about why that dog doesn't like us</li> If someone insults you saying you are bald, skinny, fat, etc. and it's true, just think about it as an honest opinion and ignore it</li> If something external affects your values, you should probably rethink them in order to get full control of your feelings</li> The best way to reply to an insult is with humor #Insults</li> To protect minorities from insults only makes them more sensitive to it</li> Reply to insults with self-deprecating humor is even more effective. If someone insults you, you may say that if he was good at insults, he would use this other form that is even better</li> Retrospective negative visualization. When you imagine that something never existed and think about how good it was because it actually existed</li> Grief is a negative emotion and we should avoid it. If a friend is grieving, we should help him overcome that</li> Don't be corrupted by pleasure, things are not hard, we are soft. Exercise discomfort</li> Our internal state resembles the external state. If you want to be better (not angry) change your external first (laugh, decrease your voice, etc)</li> Why experience anti-joy (anger) when you can experience joy? Control your anger.</li> If we seek social status, we give people power over us. We have to do things calculated so they can approve our actions</li> If we make our goal to please others, we will not be free to please ourselves</li> To tell someone you don't care about what he thinks is probably the biggest insult you can inflict — 💭 I said that many times if you're reading this and remembers me saying that to you, I'm sorry</li> The goal is to be indifferent to other people's opinions on us (good and bad opinions)</li> Happiness depends more on people's values than where they reside (talking about exile)</li> Many stoics committed suicide. It usually happened when they had no more obligation and death was near</li> Is a life which you're not ready to die for worth living? -- stoics</li> Stoics usually get many political enemies because they don't fear death nor exile and they consider their social duty to fight those battles</li> To acquire tranquility, it would be better if instead of working hard to become wealthy we train ourselves to become happy with what we have. Instead of seeking fame, we overcame our crave to the admiration of others. Instead of trying to become popular we improve our relationship with true friends</li> Stoics usually enjoy things that can't be taken from them, like their character</li> Stoics enjoy simple things and do not attach themselves to "the best things" out there</li> Stoics don't consider it good for people to consider themselves as "victims of society". If you consider yourself a victim, you will not live a good life.</li> The first step to making a good society is to teach people to not depend on external factors to living a good life</li> When you have a desire and satisfy it, a new desire will come. You will never be satisfied following this strategy. Instead of doing this, you should master desire and be satisfied with what you already have</li> One of the main sources of human unhappiness is our tendency to worry about things beyond our control</li> You should think about the past and the present, and learn from it, but without "what if"s</li> When challenging yourself to do things that cause fear or discomfort, you're challenging your other self, who is in evolution auto-pilot, always looking for pleasure, and has zero self-control. He is not your friend.</li> You should confront your other self to gain self-discipline. Self-discipline is important because those who possess it have the ability to do what they want with their life</li> "I want so few of the things money can buy" — the author of the book (and myself)</li> When I go to the mall I don't buy things, instead, I'm astonished by the number of things for sale that I don't need or couldn't even imagine myself wanting</li> </ul> Stats for Mar, 2018 Unknown — Fri, 13 Apr 2018 00:00:00 +0000 March is gone, and it's time for metrics! 📊 Books</h3> Note: I write a review for each book I read. You can find them on my Goodreads account</a>. Just one book this month, but a 5 stars one: </a> When: The Scientific Secrets of Perfect Timing</a>. This book is about optimization based on time and energy. What is the best time to do some action based on statistics? I found it to be amazing and could confirm many of the assumptions with my data. I would recommend everyone who likes to improve their performance to read this book and draw their conclusions. Articles</h3> As usual, I'm using that same export file from Pocket</a> and a script that look like the one I used last month. Here is the script with the actual data: var pocket = {"unread":1420,"unread_pct":4.79,"read":1020,"read_pct":1.18} var uls=document.body.getElementsByTagName("ul"); unread = uls[0].children.length; pocket["unread_pct"] = +((1 - pocket["unread"] / unread) * 100).toFixed(2); pocket["unread"] = unread; read = uls[1].children.length; pocket["read_pct"] = +((1 - pocket["read"] / read) * 100).toFixed(2); pocket["read"] = uls[1].children.length; console.log("# Result: " + JSON.stringify(pocket)) # Result: {"unread":1446,"unread_pct":1.8,"read":1050,"read_pct":2.86}</code></pre> It means I have 1446 articles unread and 1050 articles read. Comparing with my results from the last month (1420 unread and 1020 read), I got around 1.8% more unread articles and 2.8% more read articles. The percentages are better this month, and this is a good thing. I'm happy to see that I read 30 articles this month. 🙂 Coding</h3> Here are the charts from Wakatime</a> since the last post. I will start with editors this time: </a> Vim and Emacs usage following the same patterns. </a> This month was a very particular one since I had the Doist retreat</a> (an AMAZING experience which deserves a post) and one week vacation. Not so much coding done. </a> Python</code> is my first language but I had some Ruby</code> as well. Unfortunately, there's no mention of Rust</code> or Elixir</code> this month. 😞 Speaking</h3> No speaking this month but I helped organize a workshop about agile methodologies and how it could help our work at Doist. It was an excellent experience. Completed tasks</h3> Here is the comparison of the tasks for the last month (first) and the tasks for this month (second). I extracted it from Todoist</a>. </a> </a> Almost 190 tasks in the week I returned to work. 😅 Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 3 days of podcast time is above average for me. As usual, here is the list of Podcasts and their times: </a> Remember that this is an "all-time list", and I'm tracking time instead of the episode which makes short podcasts not to appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a> comparing the last month (first) and this month (second): </a> </a> It seems quite stable this month. I had 12 tracked working days this month, and I worked for 107 hours, which mean that I worked 11 hours more than I should (it was also 11 in the last month with more days tracked 😞). Let's check Deep work versus Shallow work: </a> What I can take from this chart: I had more meetings than usual, but it's not too bad</li> Shallow work is still 55% (better than 64% from February)</li> The Shallow work task (the most generic I have) is still the big black box. I'm trying not to split the tracking too much, or it will be too much work to manage it. Maybe it will be useful to separate lunchtime and other typical things just to check the time slacking.</li> </ul> "Read/Reply Twist" is still consuming a lot of time, almost 2 hours every day. I'm still fighting to implement my process of checking it in the morning, add tasks and just review in the afternoon. I should probably avoid doing it in the morning, but it's still hard for me. Now, let's continue to my personal projects, last month first and this month last: </a> </a> That's not much to compare here, but at least it seems stable. 👍 Here is my data from RescueTime</a>: </a> </a> It's worst than last month 😞. I had a pulse of 62, and it's now 54. I can't say why it's bad, at least I could not feel anything wrong during the last month. Maybe it was related to the travel planning. Still following my Telegram usage, here is the comparison from the previous month to the current one: </a> </a> It seems quite stable, let's wait for the next month. I'm still trying to understand if I have a particular moment where I use Telegram the most, here is the difference from the last month to the current one: </a> </a> Nothing outstanding but 10:00 is still the time I most use Telegram. It's not that good since it should be my peak time. I will have to improve my morning routine. 👍 I've added a warning when I use Telegram for more than 30 minutes in the day. That is helping me to understand my usage pattern. Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> </a> This month was better than the last one. 10.5k steps compared to 6.5k from previous month. 👍 This is expected since I had two weeks to move around because of the retreat and my vacation in Santiago. As I got back in April, it did not reflect on my weight, but the result will be horrible for the next month 😅: </a> Here is my sleep data for this month: </a> I was expecting a decrease this month. During the retreat I did not sleep that much because I was trying to enjoy every second of that experience. This month is an outlier of my routine, but I think it will be back for the next. TV Shows</h3> According to tvshowtime</a> I watched 3 episode this month: </a> But these are the same 3 episodes of the last month, so I did not watch any tv show this month. ✌ Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the number of words and errors when I'm writing. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. Here are my stats for this month: 50348 words written (72766 last month)</li> 825 corrections made (3451 last month)</li> 10944 unique words (14352 last month)</li> </ul> Nothing to extract from these metrics since it's different from the last month because of the retreat + vacations. Locations</h3> Thanks to Doist I visited Chile this month! 🙃 </a> For some reason, Argentina is on the list as well. I've been there already but not this time. :P I had one week of vacations and decided to walk around Santiago and relax. Because of that, I've added many places to the list: </a> Let's compare the difference between last month and this month. Last month first and this month right after it: </a> . </a> One new country, 12 cities, and almost 50 more places. Quite nice. 😀 It's expected to have more commuting, and walking this month: </a> . </a> Still many kilometers to "reach the moon": </a> Expenses</h3> It's time to check my expenses! 💸 </a> This month I will have to count a big investment in traveling (yes, traveling for me is an investment in many aspects). It's like that because I'm still paying some of the previous flights and I exchanged all the money before going to Chile, so I went with cash for the whole trip. It seems like I spent around 60% of my income this month, which is not regular at all. I usually spend about 40% (or less). The monthly expenses with my home ("Moradia") are finally part of the chart now, and I also added family health care on "Outros gastos". This month is an outlier, but the result is not that bad, IMO. 👍 As usual, I'm not considering the money in transit from my company to my personal account (waiting for money exchange, taxes, accountant payment, etc.). So, without considering it, my total savings increased by 3% and now I have 90.56% of my goal. Time to write this blog post</h3> Some people are asking me about how much time it takes to collect all the data and write the blog post, so I decided to add this metric It took 3 hours and 30 minutes That counts the whole process of organizing my data (I usually review my investment portfolio as well), taking screenshots, and writing this post. Conclusion</h3> This was not a normal month at all, but it was really amazing. You can't see it in my metrics (maybe the locations 🤔) but keep in mind that not all parts of your life will be on your metrics and that's OK. I put a lot of effort to create this blog post but I also know when I should enjoy life and let things go. See you next month. 🖖 Stats for Feb, 2018 Unknown — Wed, 07 Mar 2018 00:00:00 +0000 February time! Let's see what we can get from my metrics. 😀 Books</h3> Note: I write a review for each book I read. You can find them on my Goodreads account</a>. I'm quite satisfied with my reading list for this month: </a> Five books read in a month and a 4.6 average rating. That's what I call a good reading month. The Art of Learning: A Journey in the Pursuit of Excellence</a>. This was another fantastic recommendation by Amir</a>. The author was a chess prodigy as a kid and an international chess master in the age of 16. He also was highly skilled in Martial arts. In this book, he shows what he extracted from his process of learning during all those years in physical and mental arts. You can read my review on Goodreads</a>. The Richest Man in Babylon</a>. This book is a series of fiction stories using Babylon as the central topic. It's a good book but "Rich Dad, Poor Dad" ruined it for me. Reason below. Rich Dad, Poor Dad</a>. It's a great book. When I was reading it, I asked some friends why they did not recommend it before. There are some great ideas there (depending on your political opinions, you may not like it) and I saw many of them being applied in practice in my own life. It was almost a 5 stars review, but the ending was really dull. I felt he was trying to add more pages to the book. The Art of Invisibility</a>. This is the book that makes you paranoid about security (if you care about it). I recommend you to read it if you feel secure using the internet. Anything You Want</a>. An amazing book. Short, straight to the point, and with killer hints on how to Derek Sivers dealt with his business. I really recommend this one. Gather 'Round the Sound</a>. This was a free audiobook by Audible. It was nice to listen but nothing astonishing. Articles</h3> As usual, I'm using that same export file from Pocket</a> and a script that look like the one I used last month. Here is the script with the actual data: var pocket = {"unread":1352,"unread_pct":4.14,"read":1008,"read_pct":6.15}; var uls=document.body.getElementsByTagName("ul"); unread = uls[0].children.length; pocket["unread_pct"] = +((1 - pocket["unread"] / unread) * 100).toFixed(2); pocket["unread"] = unread; read = uls[1].children.length; pocket["read_pct"] = +((1 - pocket["read"] / read) * 100).toFixed(2); pocket["read"] = uls[1].children.length; console.log("# Result: " + JSON.stringify(pocket)) # Result: {"unread":1420,"unread_pct":4.79,"read":1020,"read_pct":1.18}</code></pre> It means I have 1420 articles unread and 1020 articles read. Comparing with my results from the last month (1352 unread and 1008 read), I got around 4.8% more unread articles and 1% more read articles. It seems that my unread articles list is increasing. My list of unread increased by just 1%. I'm still reading but not enough to take care of the unread list. I should probably consider not adding articles there anymore. I just have to consider if the feeling of adding items "for future reading" is worth keeping the system. More on that in the next months. Coding</h3> Here are the charts from Wakatime</a> since the last post. I will start with editors this time: </a> My Vim configuration is fixed, and it's back to 15%. 🙂 </a> Unfortunately, the screenshot is not that good, and I'm just seeing that some days after taking it. I will keep it here. Looking at this chart is interesting. I had one week of vacation, that you can easily see in the middle of the chart, but after that, I had 3 days to catch up to a lot of non-coding work to do before going full-throttle again. I'm really interested to see if this is a pattern in the next holidays. </a> Finally, I have two programming languages at the top instead of markdown</code>. :P I'm not writing on Emacs these days, and this is probably the reason I don't have so much markdown. Python</code> is my first language but I had some Ruby</code> as well. I'm quite happy with the results. Hope to have more Rust</code> or maybe Elixir</code> in the next posts. Speaking</h3> I had one presentation at Impacta tecnologia</a> this month. The title was Criando um snake game do zero com Ruby e Gosu</a>. I built a simple game from scratch, teaching the simple flows of how to do that using Ruby. It was really nice for me, hope everyone enjoyed as much as I did. You can always check my list of talks here</a>. I said that I submitted talks for two conferences last month and both were rejected. One of them was an excellent fit for the conference, IMO. I should probably improve my proposals and try again in the future. 🙂 Completed tasks</h3> Here is the comparison of the tasks for the last month (first) and the tasks for this month (second). It was extracted from Todoist</a>. </a> </a> It's reflecting my vacation, but I can see I completed much more tasks as soon as I got back. If we compare with the amount of coding I did, it tells me that I had many tasks to do, but they were not related to coding. 🤔 It's good to know that because it makes me feel better when there are not so many commits done. 👍 Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 2 days of podcast time is the average for me. As usual, it is the opposite of the number of books I "read" (listened to). As usual, here is the list of Podcasts and their times: </a> Just remember that this is an "all-time list", and I'm tracking time instead of the episode which makes short podcasts not to appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a> comparing the last month (first) and this month (second): </a> </a> There's an unusual pattern in this chart. Again, before and after my vacation I had long working hours (almost 10 hours). I had 16 working days this month, and I worked for 139 hours, which mean that I worked 11 hours more than I should (it was 13 in the last month 🎉). I should probably schedule to work for 7:30 so I would work 8 hours (Brazilian way). 🙄 Let's check Deep work versus Shallow work: </a> It's almost the same proportions I had in January</a>. What I can take from this chart: I had more meetings this month; It's happening because I'm a mentor to the other member of my team and there are some onboarding tasks.</li> Shallow work is still 64%. I said it was less than 50% last month, but I really don't know where did I get this metric. 🤔</li> </ul> "Read/Reply Twist" is still consuming a lot of time. I changed my workflow to process all Twist</a> threads quickly and add Todoist</a> task for them. I don't think it's working as expected yet because these threads always take my attention back to Twist, I have to take the control back. 🙂 The good thing is that it's entirely up to me to improve the way I deal with this problem. I will work on it. 👍 Now, let's continue to my personal projects, last month first and this month last: </a> </a> It's improving! I had a talk last month and also some freelance work to keep my Ruby/Rails skills up-to-date. 💪 I'm delighted to see that I'm back on track to my personal projects. It took around 6 months to stabilize as I predicted. Here is my data from RescueTime</a>: </a> </a> The report is finally working correctly again. The culprit for my non-productive time is Telegram. I'm keeping it closed most of the day, but it's still my main communication app. It looks like I'm spending around 40-50 minutes using Telegram on average: </a> I'm not tracking my cell phone because I usually don't use it enough to interfere with my productivity and it was just generating noise to my data. This is why I have almost no activity during vacations. I was trying to understand if I have a particular moment where I use Telegram the most: </a> It seems that around 10:00 is the time I most use Telegram. It's not that good since it should be my peak time. I will have to improve my morning routine. 👍 Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> </a> The chart shows that it's almost the same as the last month (6.5k steps), which is not that bad. I'm going to the gym almost every day. My goal is to improve my muscles and take care of my left arm after the Bankart and Hill Sachs lesion. As I'm not doing cardio exercises, my weight is still good: </a> Here is my sleep data for this month: </a> As we can see in the chart, it's almost the same as the last month, and I'm happy with that. 👍 Considering the whole user base from mi-band: </a> This chart only considers the last 7 days. My goal previous month</a> was to improve my "Fell asleep score" and it's really better now. My new routine considers sleeping at 22:30 and waking up between 6 and 6:30. As you can see, it's working really well. 😀 We just have to ignore the deep sleep for the last 7 days. ✌️ TV Shows</h3> According to tvshowtime</a> I watched 3 episode this month: </a> I forgot to add it to the app before it was too late. These 3 episodes are related to Punisher. 😀 I spent 3 hours of my life watching TV shows this month... But I also watched some movies. I'm not tracking films yet because I usually don't watch that much. Last year I watched less than 10 movies. In case I decide to start watching more movies I will consider tracking them. Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the number of words and errors when I'm writing. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. Here are my stats for this month: 72766 words written (71248 last month)</li> 3451 corrections made (2039 last month)</li> 14352 unique words (12320 last month)</li> </ul> The corrections made keep increasing, I'm sure this is happening because of Grammarly premium. It offers some "advanced" corrections. Locations</h3> Let's explore my locations. Last month first and this month right after it: </a> . </a> Just visited some places more but no new cities or countries. 😞 Let's see the time commuting, last month first and this month second: </a> . </a> Long hours spent on vehicles this month. I decided to visit my parents, and it requires at least 12 hours on a bus 😬. My time walking is almost the same. </a> Expenses</h3> It's time to check my expenses! 💸 </a> The chart seems to be back to normal. The "Moradia" (kind of a mortgage) section increased because I was not considering it in the previous months. I'm also not considering the money in transit from my company to my personal account (waiting for money exchange, taxes, accountant, etc.). So, without considering it, my total savings increased by 3.20%! Now I have 87.93% of my goal. Time to write this blog post</h3> Some people are asking me about how much time it takes to collect all the data and write the blog post, so I decided to add this metric It took around 4 hours It actually was 3:21 in my tracking software, but I spent a little bit more than that. Conclusion</h3> It's confirmed that I finally have my old routine back. It took almost 10 months to get used to the new job and feel comfortable about my tasks to be able to focus on other things as well. This is a useful metric per se. :) I have a great trip scheduled for March, and it will probably impact my metrics. Let's see how it goes! :) See you next month. 🖖 Review of The Art of Learning: A Journey in the Pursuit of Excellence Unknown — Tue, 27 Feb 2018 00:00:00 +0000 Book: The Art of Learning: A Journey in the Pursuit of Excellence</a> by Josh Waitzkin. Rating: ⭐️⭐️⭐️⭐️. Nice book. I first heard of Josh when listening to Tim Ferriss show and then I got a recommendation (tks, Amir!). The author is the guy from "Searching for Bobby Fischer" movie (http://www.imdb.com/title/tt0108065/). He was a chess prodigy as a kid and a Tai Chi Chuan champion as an adult. The links between the learning of martial arts and chess are really interesting. He tells his story while describing the techniques he described when learning new physical and mental tricks. Here are my notes: A teacher has to learn how to teach without making the student lose his love for the game</li> When he was a kid, his parents encourage discussions where he can express himself and not follow authority blindly.</li> With his teacher, when they disagree, they have a discussion, not a lecture</li> When he makes a bad move, his teacher asks why he decided to take this path and try to get to the same end using a different path</li> Let your student associate hard work with success. Don't say "you're not good at it" when he fails but "try harder next time, and you will get it."</li> The lessons learned in the pursuit of excellence mean much more than immediate trophies and glory. In the long run, painful learning mean much more than wins.</li> A man wants to walk the road, but it's full of thorns. He has two choices: clean the road and tame the nature or build sandals. Sandals are the internal solution</li> You can't expect the world to be silent. Instead, you can make peace with the noise and use it in your favor</li> Learn to deal with discomfort and pain. Don't let it ruin your concentration.</li> Michael Jordan was the guy who reached the most successes in hitting the basket in the last minute, but he was also the guy who missed it the most</li> When the body needs rest, you can still improve the mind</li> Left-handed players should use the right for some time and be skilled using it as well</li> The more experienced player sees much more than the novice</li> The key to win is to become immune to the pain. If you play to relieve the pain, you give your opponent an advantage</li> We cannot expect excellence if going with the motion is the norm of our lives</li> Stress and recovery. Physical and mental stress and recovery activities are related. You should keep your body and mind prepared to have intense activities and recover from them as fast as possible. Always plan small interval between intense activities so you can get back to them with a fresh body & mind and perform better.</li> Interval training helps you to improve your recovery abilities</li> Find some activity where you feel focused. Create a routine to get to this activity (breakfast, stretch, meditation, music, and then activity). After one month, try to use the same routine to achieve a different activity and then optimize the time it takes to get in the zone.</li> </ul> Review of The Richest Man in Babylon Unknown — Sat, 10 Feb 2018 00:00:00 +0000 Book: The Richest Man in Babylon</a> by George S. Clason. Rating: ⭐️⭐️⭐️. I just read "rich dad poor dad" before reading this one and I think it ruined my experience. After reading that book first, this one looks like a puzzle you already know the answer. This book is a series of parables of the "richest man in Babylon" (as you expect) and you need to read the parables understand the context and translate it to your life if you want to get something useful from it. That's what the "rich dad, poor dad" does. This book is not bad it was just boring for me. Given the size of the book (4h of audio) and the price (less than $3 for an Audible audiobook) it worth it. Here are some of my notes: Don't strain yourself too much, enjoy life. If 10% is all you can conformably keep, then be content to keep this portion</li> Small return and safe one is far more desirable than risk</li> We usually have more desires than we can gratify unless you contest it</li> "I'm a free man, I will enjoy my life more by expending my money on things I like". You build your budget, the idea of the budget is to help you to achieveeverything you want, not just casual things.</li> You have to take an opportunity when it arises. "I don't have time for that now" is for procrastinators</li> Five laws of gold</li> Wealth that comes quickly goes in the same way</li> The soul of a free man looks for problems to solve and solve them. The soul of a slave says: "What can I do, I'm a soul of a slave"</li> Where the determination is, the way can be found</li> He lived with 70% of his income. Paid his debt with 20% and let 10% to jingle. When he had enough and stabilized his life, he found investment for it</li> When you see the wealth of someone, you should see his work as well. Enjoy the work was what made them wealthy</li> </ul> Stats for Jan, 2018 Unknown — Wed, 07 Feb 2018 00:00:00 +0000 I'm excited to write this post about my performance for the first month of the year. I think I will have some great news at the end of this post, related to my expenses. Let's get started! 😀 Books</h3> I decided to listen to my podcasts this month, so I did not hear that many audiobooks. The only book I read this month was a physical book: </a> Hiding in unnatural happiness</a> is a book I received from a monk in York. It was the first time I heard about Krishna, Bhagavad Gita, and some other things. It was an exciting read, but 3 stars are enough for it. Articles</h3> As usual, I'm using that same export file from Pocket</a> and this time I changed the script to calculate, it will save me some time in the next month: var pocket = {unread: 1296, unread_pct: 1.00, read: 946, read_pct: 1.00}; var uls=document.body.getElementsByTagName("ul"); unread = uls[0].children.length; pocket["unread_pct"] = +((1 - pocket["unread"] / unread) * 100).toFixed(2); pocket["unread"] = unread; read = uls[1].children.length; pocket["read_pct"] = +((1 - pocket["read"] / read) * 100).toFixed(2); pocket["read"] = uls[1].children.length; console.log("var pocket = " + JSON.stringify(pocket)) var pocket = {"unread":1352,"unread_pct":4.14,"read":1008,"read_pct":6.15}</code></pre> It means I have 1352 articles unread and 1008 articles read. Comparing with my results from the last month (1296 unread and 946 read), I got around 4% more unread articles and 6% more read articles. A significant increase this month but it's great to see the books read percentage higher than the read one. Coding</h3> Here are the charts from Wakatime</a> since the last post. I will start with editors this time: </a> It looks like my Vim configuration is not working, just fixed that but my metrics were not collected. 😞 </a> It doesn't look correct, unfortunately. Some hours are missing here. 😞 </a> As usual, markdown</code> and Python</code> are present. I tried some Rust</code> as well and did some Ruby</code> coding because of my presentation and some freelance coding. Speaking</h3> No presentations were done this month. I will not post a chart for that anymore. I don't have a goal related to it this year. I submitted talks for two conferences, maybe I will have some good news next month. 👀 Completed tasks</h3> Here is the comparison of the tasks for the last month (first) and the tasks for this month (second). It was extracted from Todoist</a>. </a> </a> It looks stable again! 😀 Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 6 days and 3 hours of podcast time is a personal record for me. Of course, I did not use 147 hours of my time to listen to Podcasts, I usually speed-up them, so I would guess it was around 60-70 hours. 😀 As usual, here is the list of Podcasts and their times: </a> Just remember that this is an "all-time list", and I'm tracking time instead of the episode which makes short podcasts not to appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. I would also want to highlight that I started listening to Philosophize this podcast</a> and highly recommend you to try it. I decided to listen to 10 episodes in a row, starting from episode 1. I usually don't read about philosophy because the literature is boring as hell, but this podcast explains all the good parts of it and makes it enjoyable to listen. Hours working</h3> Here is the data from my time tracking software, Toggl</a> comparing the last month (first) and this month (second): </a> </a> I think I'm improving! I started to compute the number of hours I'm working in a day. Instead of working until I finish my tasks, I decided to set up 8 hours to work, and I have to work smarter to be able to include all tasks in this schedule. I highly recommend this strategy if you want to focus on your work and avoid over-working. We had 21 work days this month, and I worked for 181 hours, which mean that I worked 13 hours more than I should. It was the same number of hours of the last month, but this time it looks more uniform in the chart. </a> What I can take from this chart: I had fewer meetings this month; this is definitely a good metric. 😀</li> Had some time invested in hiring, but it's probably done already! 😀</li> Shallow work decreased from 60% to less than 50%, I'm thrilled to see that</li> </ul> "Read/Reply Twist" is still consuming a lot of time. I changed my workflow to process all Twist</a> threads quickly and add Todoist</a> task for them. After that, I can close Twist and focus on my tasks when I feel comfortable to research what needs to be done and reply to them. This workflow is not showing its results yet, but maybe we will have something next month. 😉 I will prepare a post about my workflow using Todoist and Twist soon. Now, let's continue to my personal projects: </a> That was a good improvement considering I did not have any time working on personal projects last month. I decided to add my freelance to this chart so it will not interfere with my metrics from Doist. Here I have my freelance work and my talks. Here is my data from RescueTime</a>: </a> </a> I found out that something was not good with my reports. It was probably related to my change to Firefox quantum. I decided to get back to Chrome for a while, and I will try Firefox quantum again as soon as the third party plugins improve. You can see in the chart the difference when it started reporting the websites again instead of just showing "firefox" as neutral time in gray. Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> </a> I got back to the average of 6.5k steps. Looking into the graph, it was almost the same as November (I was traveling in December, it should not count). I'm back to the gym this month, and it's reflecting in my weight: </a> Here is my sleep data for this month: </a> As we can see in the chart, it's almost the same but a little bit more deep sleep. 👍 Considering the whole user base from mi-band: </a> My goal is to change this chart for the last month. I want to be above average for the sleeping earlier chart and hope to have more deep sleep. TV Shows</h3> According to tvshowtime</a> I watched 22 episode this month: </a> We finished the first season of Billions, finished the 4th season of Vikings, and started Punisher. 😀 I spent 19 hours of my life watching TV shows this month. Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the number of words and errors when I'm writing. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. Here are my stats for this month: 71248 words written (93129 last month)</li> 2039 corrections made (1380 last month)</li> 12320 unique words (11979 last month)</li> </ul> I subscribed to Grammarly Premium; maybe this explains the increase in my number of corrections made, let's wait for the next month to confirm. Locations</h3> Let's explore my locations. Last month first and this month right after it: </a> . </a> Just visited some places more but no new cities or countries. 😞 </a> . </a> I'm back to my normal life with just a few hours spent in vehicles. 😀 </a> Expenses</h3> Here we go for what I was expecting! My expenses for this month! 😀 </a> This chart represents all my income for this month. I was finally able to receive the money for my work! It was hard to work for many months without receiving any payment but finally I could manage to set up my company in the right way to receive the money. It is a long story and I should write about it in the future. I received the money for my full-time job, my freelance, and for a presentation I did in a private company. It was the first time I received money for a talk in my entire life, after 40+ talks. 😀 Now looking at the pie chart, I can realize that I'm traveling a lot. I don't think it's a bad thing at all. I usually take care of my expenses when traveling so I can do frugal travels, but the airplane tickets are usually expensive. I also think the chart is like that because I don't spend that much money in my day-to-day life, so when I have expenses that are not common, it dominates the entire chart. I'm not considering the money in transit from my company to my personal account (waiting for money exchange, taxes payment and so on). So, without considering it, my total savings increased by fcking 13.46%! Now I have 85.70% of my goal. I'm feeling really good to see my savings growing again! 😀 Time to write this blog post</h3> Some people are asking me about how much time it takes to collect all the data and write the blog post, so I decided to add this metric It took 4 hours and 02 minutes to write this post Conclusion</h3> Back to the old routine and now with a cash flow again. 🙂 I'm finally engaging in the same optimized routine I had in the past, and I'm glad to see that happening again. 🚀 Review of Rich Dad, Poor Dad Unknown — Wed, 07 Feb 2018 00:00:00 +0000 Book: Rich Dad, Poor Dad</a> by Robert T. Kiyosaki. Rating: ⭐️⭐️⭐️⭐️. The first part of this book was truly amazing. I really enjoyed the way he was showing the difference that both dads tell him how to live life and invest in his future. It was really great to take children for that because some things just don't make sense for a child and are really easy to explain to the reader without having to rely on his current knowledge. After the introduction of the story, it became repetitive and was not adding so much as he did in the beginning. This is a great book to recommend to someone who doesn't like the rat race or people who don't really understand how money works. Here are my raw notes about the book: "I can't afford" should not be used. How can you afford it? Force yourself to think. Exercise your mind for financial matters</li> Our house is a liability, not an asset</li> Broke is temporary, poor is eternal. Don't be poor. It is a mental state.</li> People don't have money and think that more money will solve the problem, but more finance education will solve it.</li> People work for money because of desire</li> People say they are not interested in money, but they work 8 hours a day. That's a denial of truth</li> Desire is a trap. Your toys become more expensive each year.</li> School is not the end; it's the beginning</li> A job is a short-term solution for a long-term problem</li> Assets are things that put money in my pocket. Liability are things that remove money from my pocket</li> It's hard to motivate children to go to school today because the academic life is not keeping fame and prestige anymore.</li> People ask about how to have more money, but the real problem rely on how to spend the money they have</li> Financial intelligence is formed by four major things: Accountancy, Investing, Understanding markets, Understanding the law and taxes</li> Accountancy or the ability to read numbers</li> Investing - the science of money making money</li> Understand markets and the supply and demand</li> The law, taxes and so on</li> Winners are not afraid of losing, but losers are</li> Learn to manage risk, not avoid it</li> It's not the best writer that gets famous but the best salesman. Excellent writing and no sales = no success. Mediocre writing and good sales = success. Excellent writing and excellent sales = great success. (his experience)</li> Choose a book title to cause controversy in your field, and you will gain instant publicity (his experience)</li> The more specialized you are the more you depend on that field or company</li> The problem is not having fear but how you handle fear and losing</li> For winners, losing inspires them. For losers, losing defeats them.</li> In the beginning, don't play balanced, play hard. You can win much or lose much but your chances to succeed are better if you take risks at the beginning</li> Give something, and you will receive it back. Money, smile, friendship, whatever you want</li> Profits are made when you buy not when you sell</li> Think big. Buy big things split and enjoy the profits</li> Money is just an idea. If you want to make money just change your thinking</li> If you don't understand the difference between the three incomes (active, passive, portfolio) you're probably earning less than you could and working harder than you should</li> </ul> Review of Anything You Want Unknown — Tue, 06 Feb 2018 00:00:00 +0000 Book: Anything You Want</a> by Derek Sivers. Rating: ⭐️⭐️⭐️⭐️⭐️. Amazing book! It's worth 5 stars. I listened to it on Audible, and it's around 1h30 of audio, straight to the point. He is not theorizing about what should be right or what you should do to be successful. Instead, he is talking about his experience and what he thinks were the goods and bad choices he made. This book was concise enough and with tons of valuable information to earn this 5 stars review. :) If you want a non-fiction book to read in a small amount of time, this is the book for you. Here is my raw notes about the book: When you make a dream come true, and it becomes a business. It can be a dream coming true for other people too.</li> Business plan should take just some hours of work and be something simple</li> It's a hell yeah or a no. If you're not saying "Fuck yeah! I will do it" then it's a no. Say yes to less is the way out.</li> No plans survive the first contact with customers. Listen to your customer and adapt</li> Whatever VC, you don't need funding. Without funding, you don't have anyone to praise so you can focus on your product and customers. {tweet}</li> Don't be so protective of your idea. Ideas worth nothing without execution.</li> Do you like these terms and conditions of the websites? If not, don't include this garbage on yours. Avoid creating it until you need it.</li> Proudly exclude people. Focus on what you believe is better for your product. If this kind of user is not what you want, restrict the sign in and praise the users you want</li> No advertising. When you ask your client what they need to have a better product, will they ask to add some advertising? Then don't add it. Don't do everything for the money.</li> Prepare many plans for or many situations, don't expect one plan to rule them all. Use it for your life too</li> How do you grade yourself? What is essential for you? What makes you happy? Focus on that, not on what others think is right to do.</li> The Dao of business. The company should be ready to die for his customers.</li> He built a company to solve his musician problem. If the problem gets solved by itself, the company will not be needed anymore, and he will get back to music. It's weird for people to see that a company owner doesn't care about the death of his own business</li> Set up your business if you don't need the money. People sense it, and you will build a better product</li> Resist the urge to punish everyone for one person's mistake. Example: firewall blocking</li> Being naive is ok. You don't have to do what the world expects from you, do what you think is right</li> The key is being not having. You want to be a programmer not to have one big piece of software built. When you decide to run a marathon, you will not get a cab to take you to the finish line.</li> Trust with verifying. Trust people to do their work but verify once in a while.</li> Delegate but don't abdicate. Give power to your employees but not full power or it will not be your company anymore.</li> If you want a non-fiction book to read in a small amount of time, this is the book for you.</li> </ul> Review of The Art of Invisibility: The World's Most Famous Hacker Teaches You How to Be Safe in the Age of Big Brother and Big Data Unknown — Tue, 06 Feb 2018 00:00:00 +0000 Book: The Art of Invisibility: The World's Most Famous Hacker Teaches You How to Be Safe in the Age of Big Brother and Big Data</a> by Kevin D. Mitnick. Rating: ⭐️⭐️⭐️⭐️. It is not new to me that we have a lot of security flaws everywhere. Yes, it's scary, but that's what you sign for when you decide to use the internet. He shows some things you can do to be anonymous but it's tough and you usually don't need it to live a normal life. By "normal life" I mean: "I don't care about my privacy. I know companies are spying what I do and I'm OK with that". I'm not saying that it's OK not to have privacy, but that's what happens in the current state of the communications we have, live with it, or you will be paranoid. There are some excellent tips in this book for those who want to make things harder for non-security people/algorithms to trace their lives. I would recommend this book to everyone thinking he/she is secure because they have a green padlock next to their URL. There are not so many notes on this book, but here are some of them: Lock your phone with more than four digits</li> If you want to secure some device, start with your phone, it's the most vulnerable</li> Use strong security answers, they should not be obvious</li> 2FA asks for three things. It's usually: what do you have (bank card, cell phone), what do you know (pin), who you are (facial recognition, fingerprint)</li> Use a Tor browser mentioned on Tor website</li> Use Https everywhere extension</li> Ghostery browser plugin</li> Someone with access to your phone can see all your friends and your past location (a lot of info here)</li> Currently, you can't control your privacy anymore. Anyone can have a camera and take pictures of you on the street</li> </ul> Review of Hiding in Unnatural Happiness Unknown — Sun, 28 Jan 2018 00:00:00 +0000 Book: Hiding in Unnatural Happiness</a> by Devamrita Swami. Rating: ⭐️⭐️⭐️. I received this book from a monk while walking on the streets of York (UK) last year. I gave a small donation, and he told me to keep the book, so I decided to read it. He said it was about meditation, but it's about yoga in general (not the physical practice). I was not aware of anything related to Bhagavad Gita, Krishna, or anything like that, so it was an enjoyable reading for me. I'm a minimalist, so I tend not to follow the flow of the materialists, and most of the book makes a lot of sense for me. Here are my raw notes about the book: Materialism isn't bad. It's only bad if we use it to replace other things in life like meaning work, a good marriage, kids, and friends.</li> Humans are disposable. If we disappear from the earth, all other species will benefit from it, and no one will miss us.</li> If you think this is the only world and there is no afterlife, that's going to motivate you to make it as good a place as possible. Are you going to pray to end the crime in your city or are you going to look at the root causes?</li> Every year, desertification overtakes land one and a half times the size of Greece.</li> Humans are a virus that dominates, destroy, multiply, and expand to a different place.</li> An increase in money and luxury above basic middle-class standards doesn't increase happiness, but many (no one in a class of 200 students) want to live in the middle class.</li> Maximizers try to get the most of everything while satisficers are ok with their choices.

Unknown — Mon, 15 Jan 2018 00:00:00 +0000 Brace yourselves, this post will be HUGE TL;DR: It was a great year and I'm really glad to see the metrics and notice everything I accomplished. I don't remember the last time I posted my yearly review publicly but as I'm doing monthly posts of my stats, it makes sense to do an annual review as well. I do yearly reviews since around 2005 but I never post them publicly. I also write down my goals for the next year, so I can review them in the last week of the year (like I did some weeks ago). I write a lot of content but usually don't publish it because I try to keep this blog less personal. The stats posts are here because I really think it's great to have metrics about yourself, so you can evaluate and improve (remember: continuous improvement). These posts aim to show that in a practical way while helping me to commit to writing them monthly. I will try to follow a template like the one I use for my monthly stats</a> but I will also add some other items and notes about my goals. ✅ Books</h3> My yearly goal was to read 30 books this year and I read 31. Last year I read 42 but I decided to not be so aggressive this year and try a different strategy. The idea was to add a full review on Goodreads</a> after the book is finished, so I can think about how much I understood and retained about it. The experiment went really well and helped me with the process of adding more notes about the important parts (IMO) of the book. I'm using Google keep</a> for that, using a label for book notes. These notes help me to get into the context of the book. They are also easy to find using Google Keep's search engine when I need to find a reference. Here are the books from this year's list that I really recommend reading, with links to my review: Non-Fiction Mastery</a></li> What Doesn't Kill Us: How Freezing Water, Extreme Altitude and Environmental Conditioning will Renew our Lost Evolutionary Strength</a></li> Radical Candor: Be a Kickass Boss Without Losing Your Humanity</a></li> Spaceman: An Astronaut's Unlikely Journey to Unlock the Secrets of the Universe</a></li> Deep Work: Rules for Focused Success in a Distracted World</a></li> </ul> Fiction Rendezvous with Rama</a></li> </ul> You can always look for my whole list of books read this year on Goodreads</a>. Here are some stats provided by Goodreads comparing all the books I have registered: </a> I started listening to audiobooks</a> in 2016 and it was a huge difference in my life, as you can see in the charts above. Let's compare the books I read this year with last year: </a> 10 books less than last year but it was expected. What bothers me is that I only gave 5 stars to 2 books (comparing to 9 last year) and the number of books with 3 starts is higher than the last year. The number of books in the "audible-deal" shelf is higher this year and most of the books in the 3-stars row are on this shelf... Maybe the deal is not worth the price after all. Even with the high number of books in the 3-star row I'm happy with my results for 2017 regarding books. Mastery</a> was the shiny pearl of this year, I really like it. ✅ Articles</h3> Unfortunately, I don't have data for the whole year but I can use the data I have from March to December. I could not find a good way to track the articles I read. While I'm still looking for a better way to do that, I'm using Pocket</a> and manually checking it every month. It means that every article I read since March was added to Pocket. Sometimes I read from there but others I just add it there to count as read. In March I had 760 articles Unread and 570 articles Read. Now, using the data from my December stats post</a>, I have 1296 articles Unread and 946 articles Read. It means that I read 186 articles this year, an average of 15 articles each month. I'm aware that I will probably never read all those 1296 articles left in my Pocket account and I'm OK with that. Worth mentioning that my definition of article read is when I found some interesting and useful article and read that from bottom to end. I had no goal for reading articles but I decided to track that to understand how much I read every year. Before starting with audiobooks I was really frustrated with the state of my reading stats. I was not reading many books in the year but I had a feeling that I was reading many articles, which is not so bad. By tracking that I have the data I need to prove to myself that I'm reading enough, which helps with the impostor symdrome</a>. ✅ Coding</h3> All my coding metrics are provided by Wakatime</a>. First, let's take a look at the total time coding: </a> I confess that I was expecting much more than that. An average of 1h31 per day looks really low for me. I felt better when checking the comparison with the user base. It shows that I have almost twice as many hours coding! :) The low number of hours is probably related to how Wakatime gets the stats. </a> This year I did a lot for this blog: Changed the entire layout</li> migrated it to Hugo</a></li> converted all posts to Hugo format</li> redirected old URLs to the new content,</li> wrote 19 posts (my goal was 10! 😃)</li> </ul> It's expected to have my blog as the first in the list of projects for this year. It's really interesting to have my freelance project as the second one because I almost not work for them in the last 6 months! It says that I was working for them a lot in the beginning of the year. I'm really proud to have Todoist</a> on my list of projects this year. I'm using/following Todoist since 2007 and it's amazing to have the chance to contribute to the app. 🙂 </a> Looks like I fully switched to Emacs. I'm not using Vim as I used before but sometimes I miss some Vim features. I was talking to a friend last week about it and I mentioned that if I was still using querty (I use Colemak</a>) I would probably be still using Vim. Emacs is nice and so is Vim. :) I was using a plugin to register my terminal usage but I think it generated more noise than signal. 😞 </a> Markdown is the first one for many reasons: I wrote many posts on my blog</li> I'm responsible for Todoist</a> and Twist</a> documentation</li> I usually write long post in Emacs and then paste them to Twist</li> </ul> Other than that, we have Python, Ruby, Go, and a little bit of Rust, Elixir, and Javascript. I was playing with game development in Javascript this year and I really bet in Rust and Elixir, both languages are really great. I don't think I will have enough ground to play with Elixir this year but maybe Rust will have his time in my schedule in 2018. 😃 Go is on my top 5 list but I'm not totally comfortable as I would like to be, hope to improve it in 2018. Forget about "Other" it's related to Bash because of my plugin. 🙄 In general, these are great results IMO. 😃 ✅ Speaking</h3> I have to say that I'm really proud of myself on this one. 😃 Here is the burndown chart I created to follow up each month (nothing fancy, a simple Google spreadsheets): </a> For those who don't know yet (because I usually don't post publicly many things), I was in a "competition" with Milhouse</a>'s last year ghost. This story is worth sharing since it was part of my goals: In December 2016 I asked Milhouse about how many talks he gave and he said it was 18 talks. I was stunned. At the time, I was really proud of my personal record of 12 talks in one year and I know it was really hard to achieve this number. I asked him to post about it on his blog and here it is</a>. When I saw that, I started a competition with myself, my goal was to speak in 2017 more than Milhouse did in 2016. It looks like a time trial race in video games when you have to defeat your own "ghost" or the "ghost" of a friend. For those who played bike racer from Top Free Games</a>, it's just like that. It may look silly but I always do "competitions" like that to motivate myself. Sometimes I use my own data and others I use the data from someone I admire or someone who did amazing things. This time was really nice because I told that I was doing it to some friends (including Milhouse) and it was a cool internal joke between us. Thanks to that "competition" I could motivate myself to: Propose a talk to FOSDEM</a> and speak outside the country in a different language. Milhouse had 1 talk outside of Brazil, so I had to beat that. For this reason, I spoke in Belgium and Portugal.</li> Speak 3 times in the same conference (TDC</a>) about 3 different languages (Go, Ruby, Javascript) and 3 different fields (CLI, Web, Games)</li> Do 5 talks with live-coding. 3 of them starting from scratch, with a blank text file and 40 minutes of time (For those who don't know, one of my biggest fears was live-coding talks)</li> </ul> Met a lot of new people, studied many languages, and had a ton of fun. I really recommend this motivation hacking. It's not just for speaking, you can use it for anything you want. ✅ Completed tasks</h3> In the last years, Todoist is providing a Year in review and this year is no different. If you're a Todoist user, you can check your data here</a>. Let's check my Todoist tasks! 🙂 </a> Hm, less than I expected but still OK. I was already expecting for that but looks like Monday is the day I complete more tasks: </a> My most productive time is 16:00 and what I can't finish at this time I usually postpone at 19:00 😬: </a> I'm in the top 1% of all Todoist users in 2017! 😃 This Year in Review by Todoist is astonishing! I had the chance to contribute by helping with the pt-BR translation. 🙂 ✅ Podcasts</h3> 587 hours listening to Podcasts. If I was listening to the episodes in normal time (spoiler: I wasn't) it would be equivalent to more than 23 days of non-stop listening. My app says that I listened 17 days and 7 hours, but I decided to not trust it because I changed my Podcast application in the beginning of the year and restored a backup after it, so I don't know if it's accurate. Instead of using the value calculated by the app, I calculated month by month based on my posts. I consider that one month of extra time since I listen to Podcasts while commuting, walking the dog, washing the dishes, doing exercises, etc. It works really well for me and sometimes I change between Podcasts and audiobooks. ✅ Hours working, focusing and distractions</h3> Let's review how was my year related to work. This time I have a lot of metrics to correlate. \o/ If you're following my posts or social networks (Twitter</a> is the only one I'm using) you know that I changed jobs in June. I expect that to have a huge impact on my metrics. Let's start with time working, considering my full-time job only: </a> It increased a lot from July to December. At Doist</a>, they recommend to not work more than 8 hours a day and I'm clearly not doing that. 😞 Including my freelance job: </a> It looks more even now but I don't know if it's a good thing. I don't usually work as a freelancer but I work for 1 company for almost two years now and I really like the challenges they have there, so I would like to work for them again. To be able to do that, I have to stabilize my workday. From July to December I did almost no freelance work for this company: </a> A goal for the next year is to work smarter not harder, so I will have more time to do other things not related to my full-time job. I really like my full-time job (more than ever!) but I like to do different projects without constraints, it can be this freelance job or other activities that also bring me joy. There's one metric that makes me feel great. I've been tracking the amount of Deep work I do at work since the beginning of the year. I consider something to be Deep work when I close all external interruptions (Telegram, Slack, Email, Twist, Cellphone, etc) and focus on the work I have to do. And for this year I have this: </a> What an AMAZING thing to see. I really like when I'm on the flow state focusing on my task. That chart shows me that I was happier than before. 🙂 As I realized that it would not be possible to apply my deep work techniques in my previous job I was applying that on my freelance work. If I add to the chart all the freelance work I did for that company (features, bug busting, infrastructure) we have this: </a> Which is not that bad. 🙂 The good part is that I can apply Deep work to my full-time job instead of look for a different place to use it. 🎉 I would love to track the time I spent in meetings comparing the first semester and the second but I was not tracking it in the first semester. Now, giving that a second thought, even if I tracked, it would be more noise than signal. Sometimes you have productive meetings and other times you have "meeting that need to be done" where people keep talking about the unrelated stuff in the first 20 minutes of the meeting to speak about the productive stuff after that. So... ¯\_(ツ)_/¯</code>. I also have a metric for the time I spent doing/planning my talks this year: </a> Sometimes I did not track it at all, especially in the beginning of the year, but it's worth mentioning as well. In April and June, I was practicing for my live-coding session. 🙂 I'm also using rescuetime</a> to track my productivity. I'm not sure if my configuration is good and I keep changing them, so these metrics may not be so accurate. A good example of that is my tracking time, I'm also tracking the time at night when I'm talking to friends via Telegram or over the weekend. Let's look at the productive and distracting hours for the entire year: </a> </a> A lot of distracting hours. As it considers my weekends and nights, I don't think it's accurate. It still bothers me that "communication & scheduling" is the most used category. I will change that this year. Music</h3> I usually don't talk about music but last.fm</a> did a good "year in review" for me, so I will add some stats here. </a> </a> </a> </a> I started using the paid version of Google Music</a> this year, that explains why my "Discovery" has an increase of "558%" this year. I also almost doubled the number of artists I listened this year. Some interesting statistics are related to the time I listened to more songs. It seems that I listen to more songs between 20:00 and 21:00. It's usually when I want to do something different and need more energy. Wednesday is the day I listen to more music, I have no idea why it's so different than the rest. 🤔 And the obvious part... I listen to metal most of the time. 😜 TV Shows</h3> I will use my tvshowtime</a> stats to get some data about it. Here are my data for January and December: </a> </a> Based on that (and ignoring how much I watched in January) I can get to the conclusion that I watched 241 episodes, more than 4 episodes a week. Let's imagine that tvshowtime uses 30 days for one month. In this case, I spent 8 days and 5 hours of my year watching TV shows. As I don't usually watch TV, I will consider that 1 week and half of my entire year was spend watching TV. It's 2% of all my time spent with TV, not sure if it's good enough. Physical activity</h3> I was expecting to have an easy work on this one since I have some apps for metrics but turns out that it's not so easy to retrieve yearly information. 😞 What I did to get the information I need was to look month by month and take screenshots on my cell phone. I'm not including November and December because December is truncated in the monthly view for some reason and it would be too much work to include November alone. It was not so easy or pleasant to get that but here is the data regarding my steps: </a> </a> Nothing so unusual. It was mostly stable and I had peaks in February and October, the two months I was traveling to Europe. Regarding my sleep: </a> </a> Looks like my deep sleeping (the dark purple) increased in the second semester. It's interesting because it correlates with the dates I started in my new job at Doist. In February, when I was not working, I had a good rate of deep sleeping as well, I will assume it was stress related to my previous job. In general, it looks good to me. ✅ Words written and errors</h3> After consolidating all the data I collected from Grammarly this year I have the following: </a> I just copied and pasted all the data from all posts into a Google Spreadsheets and generated a chart, no science here. January, February and March have no data, unfortunately. The interesting metric I can get from this chart is that I'm writing a lot more and the corrections made are not increasing at the same pace. This is really great to see. 😃 Unique words are stable since I started tracking my words. Looks like my vocabulary is not increasing but I think it's normal, we usually don't use difficult words in our day-to-day life. ✅ Locations</h3> This year was amazing regarding traveling. I went to Belgium, Netherlands, Scotland, England, Portugal, Spain, and visited many different cities. I'm planning some posts about those cities for a while now, maybe someday. In one of those trips I had a goal to speak with people from other countries and had long conversations with people from Germany, Poland, Spain, Scotland, Colombia, Canada, Lithuania, Czech Republic, Japan, Brazil, Uruguay, Australia, Russia, Ireland, Portugal, India, Belgium, Bosnia, France, Argentina, and Netherlands. It was really great. 😀 Now that you know about the trips, I don't know if I can trust the data provided by Google Locations. Take your own conclusions: Unfortunately, I don't have my data for January, the first record was in February (after visiting more than 13 cities in 4 countries): </a> And this is the data for December: </a> It doesn't look so different even with all those travels. Considering that I visited Porto, Lisbon, and Barcelona in October, it doesn't make any sense. 😞 I use Google maps and Google trips to find new places to go. I'm a Google maps local guide</a> and I usually add reviews to the map. As a side-effect of that, I have stars in almost all places I go. </a> </a> I hope to have many other stars soon. :) According to matadornetwork</a>, I visited 8 countries so far: </a> ✅ Expenses</h3> I would love to do a deep analysis on this topic but unfortunately, the apps I use do not provide an easy way of doing this. The only thing I got was this chart for the last 6 months: </a> The legend in the left is not so good because I had to remove the actual values in cash to keep the percentages only. 🙄 Looking into this chart I can see that "Viagem" (travel) took almost 35% of my expenses. I tend to live a frugal life, so it makes sense to have my travel expenses taking most part of my money spent. For me, traveling is an investment and I don't regret spending money on it. It bothers me that "Compras" (general spending) is the second category of my expenses. I was expecting to have "Mercado" (groceries) here or maybe "Bares / Restaurantes" (eating out), but not "compras". I will look closely at it this year because it's an yellow flag for my expenses. Regarding my savings, it increased by 16.83% this year, considering the value I had at the end of April (I don't have data for Jan, Feb, and March). It's an average of 2.10% for each month, so if we apply that for January, February, March, and April, we would have 25.25%. In the end of the year, I had 75.10% of my savings goal. Considering that I did not receive any payment in the last 6 months, it's really great! I'm already expecting for a huge increase in my savings for January when I received the payment for the work in the last months. 😃 Time to write this blog post</h3> Well, this one took some time. 😜 I started it on the airplane, coming back from York. Unfortunately, I lost my tracking because of a software problem but I doubt I spent less than 2 hours on it, so let's consider 2 hours. After that I worked for 07h15min more, so we have 9h15min to write this blog post and it worth it, for sure. Conclusion</h3> What a great year! :) It is the first time I have that so much metrics to play with. I could get some interesting information about how was my year and how some changes influenced my behavior for good or bad. It took a lot more time than I was expecting but I hope to have an automated way to do that in the next year. I achieved almost all of my goals last year, so I don't have anything to complain. Hope that this year become even better than the last one. Stats for Dec, 2017 Unknown — Sun, 07 Jan 2018 00:00:00 +0000 Came back from a travel last month and just packed my stuff to travel again this month. Let's see if it affected my performance. Books</h3> I was traveling this month, so as usual, I'm not reading/listening to audiobooks because I prefer to focus on the place I'm visiting. For this reason, I did not finish any book this month. With that said, it is the first time I have 4 books on my reading list at the same time. </a> Elixir in Action</a> is there for some time now. I really like Elixir and want to finish it as soon as I have the time. I'm also playing with Rust nowadays, so I'm reading Programming Rust</a> as well. The art of invisibility</a> is the current audiobook and I hope to finish that as soon as I listen to all the Podcast episodes piled since last month. Hiding in unnatural happiness</a> is a book I received from a monk while in York. I'm not in a rush with this one but I want to finish soon, it's really small. Articles</h3> As usual, I'm using that same export file from Pocket</a> and the same script to calculate the amount of articles I read: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 1296 946</code></pre> It means I have 1296 articles Unread and 946 articles Read. Comparing with my results from the last month (1255 unread and 931 read), I got around 1% more unread articles and 1% more read articles. My unread count is not growing so fast anymore and that is a good thing. Coding</h3> Here are the charts from Wakatime</a> since the last post. </a> Nothing new in this chart this month. The blank parts are related to the New Year and Christmas holidays. </a> markdown</code> is usually the most used language because I write long texts in emacs before posting on Twist</a>. After that, we have Python and Rust! 😀 </a> Just removed bash from the reports and now we have Emacs as the only editor being used (it's strange to not have any Vim this month) 🤔 Speaking</h3> No presentations this month. 😀 </a> I already reached all my goals for the year and was OK to not speak during December. I admit that I tried to speak while I was in York but could not find any local meetup to speak. :P I had the chance to participate in two meetups of York developers</a> but unfortunately, there were no slots to speak. Completed tasks</h3> This is the number of tasks completed on Todoist</a>. </a> 306 tasks completed this month (98 less than last month). Many holidays and traveling in the last week of the year. I was totally off and did not check my tasks in these days, this is why I don't have many tasks done. Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 1 day and 3 hours of podcast time. I decided to not listen to any podcast while I was in York because I wanted to enjoy every single moment while walking in the streets. I usually use Podcasts as a way to escape from my boring routine in my working days but it was not boring in York. 😀 As usual, here is the list of Podcasts and their times: </a> Just remember that this is an "all-time list" and I'm tracking time instead of the episode which makes short podcasts to not appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a>: </a> The above chart is just for my freelance and the full-time job. The time doing freelance job was 0 hours this month, unfortunately. We had 18 work days this month and I worked for 157 hours, which mean that I worked 13 hours more than I should. From these 13 hours, 1:23 hours was in a Sunday but it was in the airplane so it doesn't count :P. </a> What I can take from this chart: Meetings are stable. I usually have around 4-5 hours of meetings a month. One useful weekly meeting of around 40 min and one 1-1 meeting. If necessary I have small meetings to fix certain problems.</li> Hiring was really hard this month. Many interviews and candidates/test reviews.</li> Shallow work is still consuming around 60% of my tasks (I'm not counting Hiring as shallow work, BTW)</li> </ul> This time I have a list of what I was doing with my Shallow work. Most of the time I can't describe what was it but I know part of it is my lunch time. One of the things I can spot as a time consumer here is the "Read/Reply Twist". As we are committed to meaningful communication, I tend to read most of the messages that mention me somehow and some of them are big threads discussing some important problem. It makes sense to take some time but I would like to improve it. Maybe next month 😉 Now, let's continue to my personal projects: </a> Yeah, that's right, no personal projects this month. 😞 It's kinda sad that I had not personal projects or freelancing this month. I really like to spend some time working on different projects. I think it happened for a reason: I was in a different city/country and invested all my time in my full-time job and walking around the city. I will try to keep that in my mind. 😀 Here is my data from RescueTime</a>: </a> As expected, I don't have enough data because I changed my browser for Firefox Quantum</a> and forgot to install the rescuetime extension. Shame on me. 😞 Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> </a> An average of 10k steps is good for me. It was better than November but worse than October, which was expected. And these are my steps each day: </a> My max distance was 17.3km walking in one day (I was lucky to get the tooltip to work when taking the screenshot): </a> Here is my sleep data for this month: </a> As we can see in the chart, I had more minutes of average sleeping this month (7h38m for the last month) but less deep sleeping (last month was 1h44) 😢 Considering the whole user base from mi-band: </a> I'm below average regarding sleeping earlier and on average regarding deep sleeping. TV Shows</h3> According to tvshowtime</a> I watched 1 episode this month: </a> It was probably Billions when I got home. 😀 I spent 1 hour of my life watching TV shows this month. Not bad 😉. Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the number of words and errors when I'm writing. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. Here are my stats for this month: 93129 words written (71062 last month)</li> 1380 corrections made (1091 last month)</li> 11979 unique words (17429 last month)</li> </ul> I wrote a lot this month. Almost 20k words more than last month but I also made more mistakes, almost in the same proportions. My vocabulary did not increase in the same rhythm though. Locations</h3> New cities were added this month: </a> The missing city is Durham. Here are the general data: </a> It's really weird that some countries are disappearing. 😞 Last month I had 7 countries but now I have 6 again. I used Matador network</a> to track the countries and I visited 8 countries, not 6. </a> Not so useful, but here is the time spent on vehicles: </a> It's probably the time spent in taxis from home to the airport and also related to the trip we made in North Yorkshire by van. </a> This trip removed 12k km from my distance to the moon. 👍 Expenses</h3> My expenses for this month: </a> This chart represents all my income for this month. Yes! You read that right, I finally received some freaking money after six months! 🎉 This money is still not related to my current job but I already received my payment, just need to go through the bureaucracy to be able to pay the taxes and receive that in my personal account. I will definitely write about this whole process soon. This month is finally back to normal! My total savings increased by 1.9% and now I have 75.10% of my goal. Next month will be huge! Time to write this blog post</h3> Some people are asking me about how much time it takes to collect all the data and write the blog post, so I decided to add this metric It took 3 hours and 02 minutes to write this post Conclusion</h3> I'm back to Brazil after one full month working from York</a>. I have to say that it was really great to work from a different place for some time. This was the last month of the year so expect a yearly review from me soon. 😀 Firefox Quantum ctrl-q Unknown — Tue, 05 Dec 2017 00:00:00 +0000 This will be a quick post to help people that are doing the same search as I was doing some minutes ago: "firefox disable ctrl+q". I'm using Firefox Quantum</a> for some weeks now (will probably post about it in the future) and the ctrl+q "feature" really annoys me. It's not the first time that I hit ctrl+q by accident just to see the entire browser and tabs being closed without warning. I was looking on Google and could not find anything on how to disable it. There were some extensions but none of them work on Firefox Quantum, so I decided to dig into the internal configurations. Looks like there is a configuration called browser.showQuitWarning</code> that helps with this problem. It does not disable the ctrl+q but shows a warning and you can just cancel it in case it was an accident. It's easy to enable it: Type about:config</code> in the address bar</li> It will say that it's a place for advanced users, so you have to accept the risk!</code></li> search for browser.showQuitWarning</code></li> click on it and change it to true</code></li> </ul> Firefox Quantum is really better than Chrome nowadays, hope it helps with the Quit problem. Stats for Nov, 2017 Unknown — Tue, 05 Dec 2017 00:00:00 +0000 Came back from a travel last month and just packed my stuff to travel again this month. Let's see if it affected my performance. Books</h3> </a> Read three books this month. My first book of H.P. Lovecraft, called At the mountains of madness</a> was one of them. It was an interesting experience to read it. I also read about minimalism</a> just to realize that I'm a minimalism since forever. If you like minimalism I also recommend to listen to their podcast</a> and read their website. The last book is On power</a> which was probably the worst book this year. It was so small that I could finish but I can't say that I learned a lot from it. I also started reading The Rust Programming language</a> because I'm playing with Rust a little bit. I still want to finish Elixir in Action</a> but it will take a while. Articles</h3> As usual, I'm using that same export file from Pocket</a> and the same script to calculate the amount of articles I read: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 1255 931</code></pre> It means I have 1255 articles Unread and 931 articles Read. Comparing with my results from the last month (1230 unread and 905 read), I got around 1.7% more unread articles and 1% more read articles. Almost the same growth of the last month. For me, it means that it was a good thing to check my Feedly once a week but that doesn't change the number of articles I read and it's probably the new delicious. Coding</h3> Here are the charts from Wakatime</a> since the last post. </a> The empty days are related to a holiday in Brazil and a huge amount of technical tickets and support for our APIs during that week. It was the price for the focused work in the week before. :) </a> markdown</code> is usually the most used language because I write long texts in emacs before posting on Twist</a>. I removed the bash</code> plugin from my terminal in the middle of the month so that 38% doesn't make much sense. And then... Rust! It was a fun week. </a> Nothing new here. Emacs at the top, bash being removed and Vim. Speaking</h3> Desconstruindo a web at Codus</a> tech-talks</li> Desconstruindo a web - Sua app ruby end to end at TOTVS Tech day</a></li> </ul> Here is the chart comparing to my goal for this year: </a> My first goal was to speak 19 times with 1 international talk and I reached. After reaching the first goal I set a new goal: reach 25 talks this year and I just met it. Speak 25 times in one year is more than I could have ever imagined. Now it's time to take a break and enjoy the last month of the year. :) Completed tasks</h3> This is the number of tasks completed on Todoist</a>. </a> 404 tasks completed this month (17 more than last month). This time I have some other colors on the chart. It's related to internal Todoist projects but most part of it is still personal (red) and work-related (blue). Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 2 days and 13 hours of podcast time, just 4 hours more than last month. It means that I spent a lot of time listening to Podcasts again. As usual, here is the list of Podcasts and their times: </a> Just remember that this is an "all-time list" and I'm tracking time instead of the episode which makes short podcasts to not appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a>: </a> The above chart is just for my freelance and the full-time job. Not so much time as a freelancer, though. I decided to do a deep down about the time I spent working for my full-time employee this month: </a> We had 20 work days in Brazil this month and I worked for 189 hours, which mean that I worked 30 hours more than I should. According to this data, almost 5 of those hours were on the weekends/holidays. I should really improve that. </a> What I can take from this chart: Meetings are stable. I usually have around 4-5 hours of meetings a month. One useful weekly meeting of around 40 min and one 1-1 meeting. If necessary I have small meetings to fix certain problems.</li> Hiring is taking some time. Interviewing, looking for candidates and writing down my opinions take some time</li> Shallow work is still consuming around 65% of my tasks. I'm trying to describe the tasks better so I can understand what I'm considering shallow work. Maybe I will have something next month.</li> </ul> There is another chart for my personal projects: </a> It is related to my two talks and my participation in the hangout by Farol Digital</a>. I'm still not producing a lot of content but it's an improvement. Here is my data from RescueTime</a>: </a> I changed my browser for Firefox Quantum</a> but forgot to install the rescuetime extension, so I don't have enough detailed data. It will be the same (or worst) for the next month. Here are the big offenders: </a> I just changed Twist to productive</code> instead of distracting</code>. I'm not sure if Twist deserves to be distracting because we usually talk about work there and it's not so distracting. With that said, Twist still takes a big portion of my time due to the need for communication. It's the source of all conversations at Doist, but it's up to us to not make communication overwhelming. I'm still working to have the balance between communication and "real work", let's see how it goes. Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> According to this data, I can conclude that I had a daily average of 6.3k steps (190625/30). It was kinda disappointing as it's below my average. I will work on it for the next month. :) And these are my steps each day: </a> My max distance was 8.4km walking in one day: </a> Here is my sleep data for this month: </a> Some more minutes of average sleeping (7h31m for the last month) but also less deep sleeping (last month was 1h58) 😢 TV Shows</h3> According to tvshowtime</a> I watched 36 episodes this month: </a> This month we finished Orphan Black (season 4 and 5) and started Billions. I spent 1 day and 3 hours of my life watching TV shows this month. Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the number of words and errors when I'm writing. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. Here are my stats for this month: 71062 words written (in September it was 73969)</li> 1091 corrections made (in September it was 1826)</li> 17429 unique words (in September it was 17139)</li> </ul> I'm comparing to September because October was not a typical month. I had fewer words written but I can see that I had fewer corrections made and more unique words! That makes me feel good. 😁 Locations</h3> At the end of the month, I went to York (the old York, in England, not the New York, in the USA) to work from there for 1 month. So, a new country was added: </a> I think it was actually part of the list from when I visited London but it's worth posting. The city of York was also added: </a> So, in summary: </a> One new city and 16 new places. Not so useful, but here is the time spent on vehicles: </a> It's probably the time spent in the taxi to the airport and in the bus from Manchester to Leeds and York. </a> This trip removed 11k km from my distance to the moon. 👍 Expenses</h3> My expenses for this month: </a> This chart represents all my income for this month. And again, the number is not wrong, I did not receive any money this month. The problem I described in</a> the</a> last</a> five</a> months</a> still persists, for this reason, there's no money coming yet. :( This month I finally had some good news and the process is almost done, just waiting for the final document. Hope to have something to show next month. And again... If you're reading this every month, you already know that my wife is paying all of our bills until my situation gets back to normal and I'm really glad to have someone to rely on when things like these happen. ❤ This month is back to normal and my wife helped to keep our expenses in a good shape. My total savings increased by 0.6% and now I have 73.70% of my goal. Time to write this blog post</h3> Some people are asking me about how much time it takes to collect all the data and write the blog post, so I decided to add this metric It took 3 hours and 30 minutes to write this post Conclusion</h3> Just came back from a trip last month to prepare to travel again this month. I'm writing this post from the winter of York</a>, it's -1 Celsius but feels like -7. I worked a lot this month but it enabled me to keep my work on schedule for the travel so I think it worth it. I did not receive any money yet but everything is moving forward now and I hope to have a nice December with everything set up. :) Review of At the Mountains of Madness Unknown — Fri, 17 Nov 2017 00:00:00 +0000 Book: At the Mountains of Madness</a> by H.P. Lovecraft. Rating: ⭐️⭐️⭐️. The first H.P. Lovecraft book I read/listen and now I understand what people say from his descriptions. It's interesting how he keeps the suspense until the last 5% of the book. The bad part is that it becomes boring sometimes. You want to understand was is there and why he doesn't want to talk about it but he keeps describing icy mountains and large rooms. When I finished the book I started listening to "The thing the should not be" from Metallica, because of the reference. :) Review of Minimalism: Live a Meaningful Life Unknown — Wed, 08 Nov 2017 00:00:00 +0000 Book: Minimalism: Live a Meaningful Life</a> by Joshua Fields Millburn. Rating: ⭐️⭐️⭐️. I was expecting more from this book. I listen to their Podcast and read some articles on their website. This book looks like a list of pointers to their website. I would just recommend it in case you want something to start your journey in minimalism thinking, so you can buy the audiobook and listen to it in your spare time before diving deep into their articles. As usual, there is some good information here as well. Here are my notes: We were not happy, so we tried to buy happiness, and of course, it didn't work</li> Minimalism is a tool to help you to achieve freedom</li> Eating should be considered nutrition, not entertainment</li> Write down things you did last week that doesn't align with the 5 values (health, relationships, passion, growth, and contribution)</li> Minimalists don't pursue happiness through things but through life itself</li> Eliminate sugar and processed foods from your diet if you want to feel better</li> Don't try to change other people, change yourself</li> Say goodbye to fake friends and focus on primary relationships</li> </ul> They don't say that as "you must do it!" or "you have to complete this checklist to be a minimalist" but instead, they show some ways to live a better life and recommend you to experiment with them. I really recommend you to check out their website in case you're interested in the whole minimalism thing. https://www.theminimalists.com/start/</a> Stats for Oct, 2017 Unknown — Sun, 05 Nov 2017 00:00:00 +0000 This month was very unusual because I was traveling through Portugal and Spain for work and tourism, so it will probably affect my stats a lot. With that said, let's see how it is. 😄 Books</h3> I read some pages from Elixir in Action</a>, but unfortunately did not finish any book this month. I usually don't read that much when traveling, so it's sad but expected. 😞 Articles</h3> As usual, I'm using that same export file from Pocket</a> and the same script to calculate the amount of articles I read: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 1230 905</code></pre> It means I have 1230 articles Unread and 905 articles Read. Comparing with my results from the last month (1214 unread and 898 read), I got around 1.5% more unread articles and 1% more read articles. I think it was a good think to not read my Feedly in a daily basis but weekly instead. I was adding a lot of articles to my Pocket account but was not reading them so it was wasted time. By checking weekly, I can still catch good articles without dedicating daily time for it. Coding</h3> Here goes the charts from Wakatime</a> since the last post. </a> The empty days are related to the days-off I took to walk around Lisbon, Barcelona, Madrid, and Toledo. The first half of the month I was working from the Doist office in Porto and the second half I was working home. It was almost the same, excluding that Tuesday when I worked more than people usually do in the office. :P </a> And not it makes sense for me. Bash</code> first and Python</code> right after. :) </a> Emacs</code> before bash</code>, that's nice. It's kinda contradictory with the previous metric but it's acceptable given that I can run many commands at once. I'm not sure if it's a good idea to keep bash</code> here, maybe I will just remove this plugin. Speaking</h3> Snake game using Python and PyGame</a> at Porto Python</a></li> </ul> It was really nice to speak at Porto Python in Portugal. It was kinda funny because of the Portuguese differences that I don't know, so I probably mixed up many words. Thanks to Roman Imankulov</a> for inviting me to speak. Here is the chart comparing to my goal for this year: </a> The new (bonus) goal is to reach 25 this year. Not sure if I can do that. :) Completed tasks</h3> This is the amount of tasks completed on Todoist</a>. </a> 387 tasks completed this month (22 more than last month). Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 2 days and 17 hours of podcast time, 1 day more than last month. It happened because I decided to catch up to the unheard episodes when I got home. 😄 As usual, here is the list of Podcasts and their times: </a> Just remember that this is an "all time list" and I'm tracking time instead of episode which makes short podcasts to not appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a>: </a> The above chart is just for my freelance and full-time job. As you can see, I took many days totally off. :) </a> I tried to use Toggl when I was in the office just to compare with my productivity at home. It was almost the same as if I'm working from home, so kudos to the Porto office. :) There is another chart for my personal projects: </a> As expected, just the time related to my talk at Porto Python. I will not post my data related to rescuetime this month because I was working in the fix for my problem and their team fixed the problem. Rescuetime stats will be back next month. :) Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> According to this data, I can conclude that I had a daily average of 11.6k steps (359/31). I think mean</code> is not a good aggregation function for this data because when I was traveling I had days like this: </a> Well... I really like to walk when I'm traveling. :) Unfortunately, my Google fit is missing some data, so I will not post all charts as usual. </a> Here is my sleep data for this month: </a> Almost the same as the last month but 10 minutes more for avg sleep and avg deep sleep. There are some comparisons with their database: </a> I'm not so bad after all. :) TV Shows</h3> According to tvshowtime</a> I watched 15 episodes this month: </a> When I got back, we decided to watch Stranger Things (season 2) and get back to Orphan Black (season 3). It's still difficult to calculate how much time I spent watching TV this month (because I could not track last month in a good way) but I think I watched 17 hours of TV. I used tii.me</a> to calculate the second season of stranger things and calculated 40 min for each of the 5 episodes of Orphan black. Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the amount of words and errors when I'm writting. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. My stats for this month: 49657 words written (last month was 73969), 26487 of them written in the last week of October</li> 1212 corrections made (last month was 1826), 772 of them made in the last week of October</li> 12725 unique words (last month was 17139), 5806 of them written in the last week of October</li> </ul> This month is really atypical and should not be compared with the previous month but it has its own interesting facts. The last week of October was really interesting. I had a lot of material to compile and write down for my team. For this reason there is a lot of words written. Locations</h3> This section is really nice! 😁 As I said, I visited two new countries: </a> And 5 new cities: </a> Unfortunately, the email sent by Google timeline was not so descriptive this time. But the other 2 cities are Toledo</a> and Lisbon</a>. So, in summary: </a> It was almost 100 new places visited 😱. Here is the time spend in vehicles: </a> I was expecting more time than that, but it looks accurate in case it's not considering airplanes. I took a train from Lisbon to Porto (3.5 hours) and a train from Madrid to Toledo and back (1.5h maybe). </a> Hope to reach the moon some day. Expenses</h3> My expenses for this month: </a> This chart represents all my income for this month. And again, the number is not wrong, I did not receive any money this month. The problem I described in the</a> last</a> four</a> months</a> still persists, for this reason, there's no money coming yet. :( Part of the problem seems to be solved and now I'm back to the normal process. Hope to have everything set up this month. If you're reading this every month, you already know that my wife is paying all of our bills until my situation gets back to normal and I'm really glad to have someone to rely on when things like these happen. ❤ I traveled to Europe last month and part of the expenses were paid by me to receive the reimbursement for it later. As I'm not able to receive my payment for some time now, it caused a negative impact in my savings. My total savings decreased by 1.31%, which means that I have 73.26% of my goal. 😢 Time to write this blog post</h3> Some people are asking me about how much time it take to collect all the data and write the blog post, so I decided to add this metric It took 4 hours and 10 minutes to write this post Conclusion</h3> It was a great month. I forgot about the whole problem of not being able to receive any money and took the whole month to meet new people and places. 😄 It was really nice to meet 12 people (from 8 different countries) of the team in person and also represent the company at hackUPC</a>. During this trip I decided to say in hostels most of the time to talk to people from different cultures (and also because I had to pay for it... 😄). I talked to people from Germany, Poland, Spain, Scotland, Colombia, Canada, Lithuania, Czech Republic, Japan, Brazil, Uruguay, Australia, Russia, Ireland, Portugal, India, Belgium, Bosnia, France, Argentina, and Netherlands. It was not just a "Hi, where are you from?", most of them were 30min+ conversations and some of them took more then 2 hours. I also bought a sword (a replica of Andúril), but that's a story for a different post. :D So...mission accomplished for this month. o/ Review of On Power Unknown — Thu, 02 Nov 2017 00:00:00 +0000 Book: On Power</a> by Robert A. Caro. Rating: ⭐️⭐️. Not that much to learn from this "book". It's really small (almost two hours of audio) and looks like an abridged version of a collection of other books. I'm not American, so I'm not part of the context or his target audience and maybe it also plays some role here. The whole thing about the electricity was a reality for my mom (and for me when I visited my grandparents as a child) in Brazil, it may be shocking to people living in New York nowadays but I already knew all of that in my own context. The power examples of power were not so good as I expected, maybe because there is not so much time to tell a good story. Maybe Caro has some good materials out there but I don't think this is one of them. Antwerp Unknown — Tue, 31 Oct 2017 00:00:00 +0000 In 2017 I had the chance to speak at FOSDEM</a> in Brussels</a>, and I used this opportunity to travel around Belgium a bit, one city every day. One of the cities I visited was Antwerp. Being very honest, it's definitely not a city I would visit again. The best part of the city for me was the train station, which is trully beautiful. I would recommend people to stop there, see the train station and move on. Stay</h2> TBD Transport</h2> I did everything walking, the city is not that big and I like walking. I got the train to get there from Ghent and then got the train again to go to Rotterdam</a>. The main reason why I decided to stop in Antwerp was because it was literally in the way of going to Rotterdam from Ghent. Places</h2> The train station is quite nice. It's the place I spent some time, just looking around.</li> </ul> Food</h2> Nothing that I remember and it's worth listing. Just cheap food and nice fries. :)</li> </ul> Antwerp Unknown — Tue, 31 Oct 2017 00:00:00 +0000 In 2017 I had the chance to speak at FOSDEM</a> in Brussels, so I explored the city with some friends. Brussels is a big city, but I didn't have any problems navigating it. The experience was great, actually. Stay</h2> It was my first time ever trying a hostel. Looking now in retrospect, the experience in Brussels was not great, but at the time I found it quite interesting. I stayed in the hostel 2G04. It has an amazing location, it's like 3 minutes by foot to get to the main square of Brussels. The main square is just astonishing, so the hostel was nice in this regard. The experience with this hostel was not the best. I forgot to bring a lock and there were not many people there to ask for help. The bathroom was quite weird. Not dirty or anything like that, just not comfortable at all. I wouldn't recommend this hostel in particular, but it was better than one that a friend got for the same date. I remember leaving there with a feeling that it was not the best, but could be much worse. Transport</h2> Brussels is a big city, I used the tram and busses a lot to navigate the city. I don't really remember what I did to pay for the rides, but I think I got their transport cards and it worked well. It was nice to see for the first time that they had no specific mechanism to block people from entering the tram or train if they don't validate the ticket. People can just go in and out without validating the ticket, and if they are lucky enough, nothing is going to happen to them. If they are not lucky, they will get a fine for it. I'm not sure if this is something people do, but for a brazilian, it was quite interesting to see this happening. The trains work great too. It's a bit complicated to understand how they work if you're not used to it (which was my case 😅). Once you get your ticket, you just have to go to the right platform, wait for the train going to where you want to go and go in. It was not obvious for me if the train was right or not, I asked and people gave me enough guidance for me to go in, but it could totally go wrong for someone not used to it. Places</h2> I enjoyed the visit to the Atomium. It's a nice structure and a science museum.</li> I decided to go for the Manekin Piss, just to see the famous statue. Nothing outstanding there, but was worth the visiting.</li> After visiting the Manekin piss I went for the other two statues that follow the same pattern. I quite enjoyed seeing the peeing dog. 😅</li> </ul> Food</h2> I went for a restaurant in the main square in the first day and it was quite nice. Don't really remember the name though. 😕</li> I went to Delirium, for some beers. I don't really like beer, but it was definitely a good experience to visit the place.</li> </ul> Stats for sep, 2017 Unknown — Tue, 31 Oct 2017 00:00:00 +0000 It's already the end of October and I could not manage to post my stats from September but I have a good reason for that (which you will read about in the next month 😉). Books</h3> </a> What Doesn’t Kill Us: How Freezing Water, Extreme Altitude and Environmental Conditioning Will Renew Our Lost Evolutionary Strength</a> is a book that describes what the human body can do if trained for it. The writing process is not so good for my taste, sometimes it looks like a memoir, sometimes it's non-fiction... but the message it passes is really interesting. The evolution did a lot of work for us but we're kind of using technology to do some stuff for us and losing part of what we developed. I recommend it, BTW. It was really less books read then last month, but it's ok. I had a lot of pressing things to do this month. Articles</h3> As usual, I'm using that same export file from Pocket</a> and the same script to calculate the amount of articles I read: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 1214 898</code></pre> It means I have 1214 articles Unread and 898 articles Read. Comparing with my results from the last month (1157 unread and 883 read), I got around 5% more unread articles and 2% more read articles. I did not take so much time for articles reading this month, so the numbers increased less than they use to. It was also affected by the time it took to generate the numbers last month. Another correlation with this one may be related to the fact that I'm only reading my Feedly once a week instead of every day, that helps a lot to not add many articles to Pocket. :) Coding</h3> Here goes the charts from Wakatime</a> since the last post. </a> As usual, it's kind of the average with one outlier. This average of 3-4 hours coding always bugs me. </a> I don't know why markdown</code> always takes the lead (after bash</code>), but Python</code> is coming as it should. </a> Nothing new to editors. I still use Vim, but Emacs is the leader by far. Speaking</h3> Fazendo um snake game com Python 3 e PyGame para se divertir</a> at GruPy-SP</a></li> Lightning talk: Brincando com API's e jq</a> at Guru-SP</a></li> </ul> This was an ordinary month regarding presentations, but still following what I had defined for my goal: </a> The goal was reached this month! I will try to keep the same rhythm and maybe speak in different countries in October. :) Completed tasks</h3> This is the amount of tasks completed on Todoist</a>. </a> 365 tasks completed this month (169 less than last month 😞). Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 1 day and 16 hours of podcast time, almost 1 day more than last month. As I said in the previous month, when I listen to less audiobooks I usually have more time spent on podcasts. 😄 I decided to keep a list of the Podcasts and their times as well. </a> Just remember that this is an "all time list" and I'm tracking time instead of episode which makes short podcasts to not appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a>: </a> The above chart is just for my freelance and full-time job. Currently it's just my full-time job, because there are some stuff preventing me to work on my freelance. Here is the difference between shallow and deep work regarding my full-time job: </a> It was less deep work than last month (10 hours less) but it's good to know I'm still spending around 1/3 of my time in Deep Work state. I'm also tracking time in meetings and it was half of the time spend last month. 😁 There is another chart for my personal projects: </a> A little bit more personal projects but they are all related to my presentations. :) Here is my data from RescueTime</a>: </a> Unfortunately I had a problem with Rescue time this month (and probably next month too, we're debugging it) and my data is not being collected properly. 😢 But there is not just bad news for this case! I now have a partnership with rescuetime and have access to a premium account. Thanks rescuetime team! 😁 Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> According to this data, I can conclude that I had a daily average of 8.6k steps (258/30). It was almost 50k more steps than last month, which is really good. And these are my steps each day: </a> My max distance was 9.2km: </a> Here is my sleep data for this month: </a> Less average sleeping (7h49m for the last month) and also less deep sleeping for this month (last month was 1h48). TV Shows</h3> According to tvshowtime</a> I watched 50 episodes this month! It's a personal record but I'm not sure if this is good or bad. </a> It's a combination of The defenders, Marvel agents of shield (season 4) and Orphan Black (seasons 1-3). Unfortunately I got the results too late and I can't calculate how many hours I spent watching TV this month. 😢 Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the amount of words and errors when I'm writting. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. My stats for this month: 73969 words written (69493 last month)</li> 1826 corrections made (1881 last month)</li> 17139 unique words (13925 last month)</li> </ul> The numbers keep rising because all of my work conversations are in English and that's nice. I had more than 6% more words written , around 19% more unique words and 3% less corrections made (!!). It was great to see less corrections made this month, it seems I'm improving! 😄 Locations</h3> For some reason, there is 1 city less than next month. I really don't know how Google calculates that. 😞 But visited 11 places this month. </a> Here is the time spend in vehicles: </a> Just 10 hours spent in transport, that's great. :) </a> Hope to reach the moon some day. Expenses</h3> My expenses for this month: </a> This chart represents all my income for this month. The number is not wrong, I did not receive any money this month. The problem I described in the last</a> three</a> months</a> still persists, for this reason, there's no money coming yet. :( So... the situation is the same... My wife is paying all of our bills until my situation gets back to normal. I'm stressed with this situation but it's great to have someone to rely on when things like these happen. ❤️ Unfortunately I did not checked all my finances in the beginning of the month, so I can't tell how it was. I will keep the same value as the last month, so I still reached 74.23% of my goal. Time to write this blog post</h3> Some people are asking me about how much time it take to collect all the data and write the blog post, so I decided to add this metric. It took 3 hours and 16 minutes to write this post I wrote part of it during an airplane travel so its approximate. Conclusion</h3> Again... excluding the fact of not being able to receive my payment because of bureaucracy that has nothing to do with what I do, this month was good. I had to rush to get everything setup for my travel in the next month but it was cool. I'm already aware that the next month will be really different because I will take 1 week off and will work from different locations. Let's see how it goes. PotHix ❤ Doist Unknown — Mon, 30 Oct 2017 00:00:00 +0000 TL;DR: I'm working on something I really believe is good at Doist</a> and I feel great. As I mentioned on this post</a> (in pt-BR) I left the company I was working for the last year to join a new company. The new company is Doist</a> and I'm working for them since July. Some time ago a friend asked me why I joined Doist and I realized it's kind of a love story so I decided to write the post. 😄 For those who are not aware of Doist, it's the company behind Twist</a> and Todoist</a>. Twist is a communication tool that aims to make remote communication work better for remote teams and Todoist is the best task manager I know. I joined the company in July as I said but I'm a Todoist user since 2007</a> (this link requires yahoo groups membership, it's free but required) and I always recommended my friends to use it. I tried many task managers in these 10 years but I always get back to Todoist. When I started my career as a software engineer in 2006, I decided to also look for a better way to deal with my tasks. My memory is not very good, so I decided to look for a system to help me with that and found GTD. For some time I was one of the moderators of gtd-br, probably the biggest GTD mail list in Brazil at the time and was looking for an application to manage my tasks. I was looking for something clean, lightweight, simple, and with support to keyboard shortcuts. Tried Toodledo, Remember the milk, thinking rock, and some others but none of them were good enough. I was about to create my own when I found Todoist, it was exactly what I was looking for. As an active user, I was always following the new features and the usage of new technologies in the product. I remember when they started using HTML5 for their mobile application, it was really great to see it. At some point I found that a company called Doist appeared as the creator of Todoist (it was just Todoist before that) and I started looking to their job board. There were not so many positions and all of them required a good level of Python. My focus was always Ruby and I didn't have any experience with large Python projects at the time. Some years passed and I had the chance to work on some Python projects at work and gained some experience. I even created a personal project in Python to do some scrapping for some financial data I wanted, it became a big project but it was abandoned after Google Finance implemented my main feature. :P When the time for a change came I decided to apply for companies I admire and who believe in the same things I do. I also changed my mindset and decided to not look for technology anymore but for products I believe are really good and can recommend to my friends and family. I worked for 5 companies in the past and none of their products were something I can really recommend to everyone. Most of them don't even exist anymore. Others are relatively good in one specific use case and country. I was working for these companies because there were great people, good salary/benefits, or great technology. When I saw the position to "API & Integrations" developer at Doist I decided to apply. I was kind of insecure about the platform change (Ruby -> Python) but I believe languages are just tools to build stuff and I had enough experience to be proficient with Python. I also love to create tools for developers and did that in the past many times already, so it would be a great fit. During the interviewing process I found that it was a perfect match of beliefs: Remote working</li> Async working (not fixed hours, we believe you will do you job and will follow your metrics)</li> Chance to travel and meet different people/cultures</li> We read nice books and actually apply their concepts (radical candor, the score takes care of itself, let my people go surfing)</li> Bootstrapped company</li> Amazing perks for remote working</li> Almost the same salary I had</li> </ul> I was already doing remote work 70% of the time for my previous company and I also have a freelance job for a company in Netherlands, so I'm used to remote working already. With that said, I took the job. :) Of course not everything is rainbows and unicorns, as everything in life, but the overall experience is really great. At this moment, I'm writing this blog post in the airplane (airplanes are the bad part :P), coming back from a trip where I met 12 members of the team (we're 50+ at the moment) in two different countries. I also was the person of contact for all hackers doing our challenge at the HackUPC hackathon in Barcelona, which helped me a lot to collect feedback of our APIs. The whole thing about the "love story" I mentioned in the beginning of this post is that Todoist helps me since the beginning of my career and now, after almost 10 years, I have the change to work for the company behind it. What is even greater is that the company has the same mindset and beliefs I have. For this particular case, instead of using technology to retain talent, Doist built the best product ever, which made me consider applying to make it even better. Review of What Doesn't Kill Us: How Freezing Water, Extreme Altitude, and Environmental Conditioning Will Renew Our Lost Evolutionary Strength Unknown — Thu, 14 Sep 2017 00:00:00 +0000 Book: What Doesn't Kill Us: How Freezing Water, Extreme Altitude, and Environmental Conditioning Will Renew Our Lost Evolutionary Strength</a> by Scott Carney. Rating: ⭐️⭐️⭐️⭐️. It was 3 stars most part of the book but I actually learned some stuff and added some pointers for further research, so it deserves a 4. The good part of this book is to convince you, or at least inspire you to research a little bit on the topic, that we can be more than what we are now. The human body is capable of many extraordinary things but we usually don't practice methods to improve ourselves. The technology around us made us lazy for many things and it may be a disadvantage for some situations or even for evolution purposes. The bad part is the structure, the feeling was like: 0-50% - Great, I'm skeptical but it makes sense, many pointers to further research</li> 50-80% - A lot of stories from people who tested the methods from Wim Hof, kinda boring</li> 80-95% - Memoir of his adventure after training</li> 95-100% - Some good data on the results of the whole training comparing to the initial tests</li> </ul> Here are some of my notes, most of them are pointers for further research: Froid: the pleasure principle</li> Super tasters are people who have a very sensitive taste (PTC sensitivity)</li> Tetrachromacers are people who see 100M colors instead of 2.4M</li> Absolute pitch. Define a note of the piano without any reference</li> Synesthesia, people who see colors and feel the smell or taste</li> Absolute pitch is a biological condition and must be trained to become perfect pitch. If not trained it may be disabled by disuse</li> Considering the evolution theory, may be a relation of the loss of body hair with the ability to make fire</li> When holding breath, it's not the need of new oxygen that makes the urge to breathe, but the amount of CO² to be expelled. If you let it go out a little bit the body alarms will stop for a while.</li> Meditation helps to lower the brain activity and consume less energy</li> Laird Hamilton (giant waves)</li> Wim Hof (iceman)</li> </ul> Summary: It's worth reading. :) Stats for Aug, 2017 Unknown — Thu, 07 Sep 2017 00:00:00 +0000 September is here, time to review my stats for August, 2017. Books</h3> </a> This is my personal record of books read in one single month. 7 freaking books. 😱 Let's start with two small books I read. Cesar Millan's Guide to Audiobooks for Dogs</a> and Cesar Millan's Guide to Bringing Home a Shelter Dog</a>. These two books were free on Audible for Dogs</a>, so I decided to give them a try. They are ordinary books but I would recommend for dog lovers. :) Radical Candor: Be a Kick-Ass Boss Without Losing Your Humanity</a> is one of the best books I read on leadership. There's no magic here, just deal with people in the right way. Give sincere feedback, expect sincere feedback, understand their career paths and let them go if the job is not good for them (and vice-versa). I recommend every boss to read it. Seriously. Leadership and Self-Deception: Getting Out of the Box</a> is a book that helps you to think about your attitude before judging people. Not amazing, but it's a good one. The Destroyer of Worlds</a> was a recommendation from Amir</a> and until now none of his recommendations disappointed, so I decided to try it. The content is really amazing! A lot of context about the political and moral problems of the atomic bombs. I really recommend to listen to it if you like the subject. The descriptions of the Japanese of Hiroshima and Nagasaki are really hard to listen though. It's not a book, but you will consider that as a book as soon as you listen to it. My Favorite Universe</a> is a great book to introduce people to science. Neil deGrasse Tyson has the ability to show complicated stuff in an uncomplicated way. The example of density with the cream on his hot chocolate is really nice. Rendezvous with Rama</a> is one of those books I was not expecting to like but turns out to be one of the best books I read in the genre. The way Arthur C. Clarke describes Rama and how everything works there is really amazing. Totally recommended. Articles</h3> As usual, I'm using that same export file from Pocket</a> and the same script to calculate the amount of articles I read: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 1157 883</code></pre> It means I have 1157 articles Unread and 883 articles Read. Comparing with my results from the last month (1044 unread and 777 read), I got around 10% more unread articles and 12% more read articles. It increased the percentages of read and unread because it took some time to generate the numbers. Anyways, the problem persists, I usually don't read the articles I mark to read. Looks like Pocket is my new app for bookmarks... Yay! :( I'm using it to mark all the articles I read throughout the month, so it's not that useless but I will have to reconsider the idea of reading all articles I have there. Maybe start producing instead of consuming, which is one trend I've been seeing a lot nowadays. Coding</h3> Here goes the charts from Wakatime</a> since the last post. </a> As usual, it's kind of the average with one outlier. This average of 3-4 hours coding always bugs me. </a> I don't know why markdown</code> always takes the lead (after bash</code>), but Python</code> is coming as it should. </a> Nothing new to editors. I still use Vim, but Emacs is the leader by far. Speaking</h3> Desconstruindo a web: Entendendo uma requisição</a> at Interdevops</a></li> Uma requisição web do começo ao fim at Tech-hour Catho.</li> </ul> This was an ordinary month regarding presentations, but still following what I had defined for my goal: </a> The goal was reached this month! I will try to keep the same rhythm and maybe speak in different countries. :) Completed tasks</h3> This is the amount of tasks completed on Todoist</a>. </a> 534 tasks completed this month (20 less than last month). I still have plans to create a better way to extract data from my Todoist account, just need some spare time. Not so easy these days. Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 1 day and 16 hours of podcast time, almost 1 day less than last month. This is a trend I've been following, when I read (or listen to) more books I consume less podcasts. :) I decided to keep a list of the Podcasts and their times as well. </a> Just remember that this is an "all time list" and I'm tracking time instead of episode which makes short podcasts to not appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a>: </a> The above chart is just for my freelance and full-time job. It's really hard to work as a freelancer now, my full-time job is taking all my energy, so most part of it is dedicated to it. Here is the difference between shallow and deep work regarding my full-time job: </a> It was less deep work than last month (13 hours less) but it's good to know I'm still spending around 1/3 of my time in Deep Work state. I'm also tracking time in meetings, it was almost one day in meetings this month. I did not track every single meeting because it would be too much work, but it was basically related to: 1-1 meeting</li> Weekly status (30 min each)</li> Meeting with other members of the team</li> Useful meetings with other teams and thirty parties</li> </ul> I hate useless meetings but all of these were useful and needed. :) There is another chart for my personal projects: </a> Even less than last month, it makes me sad :(. Here is my data from RescueTime</a>: </a> It's sad but I missed my goal for this month. Looks like it was pretty close (99%): </a> BTW, my goal is 3h using only productive apps, the idea is to improve the usage of these. Here are the big offensors: </a> Yeah, communication and Scheduling. I really want to spend less time in Twist</a>. It's the source of all conversations at Doist, but it's up to us to not make communication overwhelming. I'm still working to have the balance between comunication and real work. Time to improve this. :) Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> According to this data, I can conclude that I had a daily average of 6.6k steps (207/31). It was almost 50k less steps than last month. I was not feeling good some days so I had to skip the gym, maybe this is the cause of that. And these are my steps each day: </a> My max distance was 9.2km: </a> My weight is stable: </a> And here is some data on my current weight: </a> MiFit app interface for sleep data changed a little bit but here is my data for this month: </a> A bit more average sleeping (7h32m for the last month) and more deep sleeping for this month \o/ (last month was 1h32). It's probably not related (at least not in particular) to the change of bands (Mi band -> Mi band 2), because I'm using it for two months now and my deep sleeping improved for the second month. Here is my stats comparing to the whole Mi band user base: </a> Not so good, I think. 😅 TV Shows</h3> According to tvshowtime</a> I watched 24 episodes this month. </a> It's a combination of Westworld (recommended, BTW), The defenders, The crown, and Game of Thrones. Note that I had some delay to get this screenshot and there are some numbers from September already (blue arrow). With that said, I think I spent around 24 hours watching TV this month. Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the amount of words and errors when I'm writting. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. My stats for this month: 69493 words written (51018 last month)</li> 1881 corrections made (1272 last month)</li> 13925 unique words (10332 last month)</li> </ul> The numbers keep rising because all of my work conversations are in English, that's nice. I had more than 20% more words written , around 30% more unique words, but also more than 34% more corrections made. Locations</h3> This time I have one additional city in the list because I traveled to bebedouro to speak at interdevops</a>. It also helped to increase the list of places visited by 9. </a> Here is the time spend in vehicles: </a> I know I spent 9 hours traveling to speak at interdevops and 3 hours to speak at Catho, so 12 from these 14 hours are related to my presentations. Pretty good. Just want to say it again: Remote work FTW! And as always, the funny metric: </a> Hope to reach the moon some day. Expenses</h3> My expenses for this month: </a> This chart represents all my income for this month. The number is not wrong, I did not receive any money this month. The problem I described last month</a> and the month before it</a> is not solved yet, for this reason, there's no money coming yet. :( My expenses are normal again but I'm not paying anything, my wife is paying all of our bills until my situation gets back to normal. I'm kinda stressed with this situation but it's great to have someone to rely on when things like these happen. ❤️ Well, thanks to the volatile economy in Brazil, my total savings increased by 1.9% and I did not add any money to it (because I'm not receiving anything...). Now I reached 74.23% of my goal. Time to write this blog post</h3> Some people are asking me about how much time it take to collect all the data and write the blog post, so I decided to add this metric. It took 3 hours and 52 minutes to write this post 1 hour more than last month, I need to improve it for next month. Conclusion</h3> Excluding the fact of not being able to receive my payment because of bureaucracy that has nothing to do with what I do, this month was good. I'm integrated to the team and getting used to the code and the team way of work. It's really nice to work on products you love and also see people using it and giving nice feedback. I was missing that for a long time. :) The next step is try to improve my productivity for the next month. Let's see how it goes. Review of Rendezvous with Rama (Rama, #1) Unknown — Thu, 31 Aug 2017 00:00:00 +0000 Book: Rendezvous with Rama (Rama, #1)</a> by Arthur C. Clarke. Rating: ⭐️⭐️⭐️⭐️. I tend to not read much science fiction but this is a great book. I'm a big fan of J.R.R. Tolkien because I love the way he used to build his world. I found Rama an amazing place where things work in a different way but following most of the same laws we have. Arthur C. Clarke writes in a nice way, adding the exact number of details you need to feel immersed in the story without adding too much information. I'm now curious about the other Rama books. 😬 Review of My Favorite Universe Unknown — Wed, 23 Aug 2017 00:00:00 +0000 Book: My Favorite Universe</a> by Neil deGrasse Tyson. Rating: ⭐️⭐️⭐️⭐️. A good book to introduce physics to common people. Neil deGrasse Tyson is great at explaining complicated topics in a simple way. The explanation of dense objects using hot chocolate and cream was really nice for me (no spoilers, read it! :D). Did you watch Cosmos? Do you like to (or at least used to) follow Discovery Channel space documentaries? In case your answer is yes to any of these questions, you probably already know most part of this book. It's worth reading in case you want a second chance with a different kind of explanation. Here are some of my notes: Big and dense objects are round because of gravity, but small ones are not so affected</li> Neutron stars are the most round objects we have because of their incredible gravity. Even the height of a piece of paper would require a lot of energy to "climb"</li> Take a 2 hundred thousand kilometers cube and take a number of atoms it will have in the vacuum. It will have about the number of atoms it has in the air of your refrigerator</li> The famous dark energy is a kind of anti-gravity</li> The density of water, human beings, and the sun are almost the same</li> Matter tells space how to curve, space tells matter how to move</li> Io (Jupiter moon) has the most active volcano of the milky way</li> Europa (Jupiter moon) has liquid water</li> The universe is expanding and farther galaxies are expanding even faster, 3 times faster</li> It doesn't matter if you like the big bang but this is the most consistent explanation we have considering the current data available</li> We are carbon based life</li> You can make more molecules with carbon than with all other elements combined</li> </ul> Review of Cesar Millan's Guide to Bringing Home a Shelter Dog Unknown — Mon, 21 Aug 2017 00:00:00 +0000 Book: Cesar Millan's Guide to Bringing Home a Shelter Dog</a> by Cesar Millan. Rating: ⭐️⭐️⭐️. Nice book for those thinking about adopting a shelter dog and did not research it yet. I adopted my dog from a local shelter, he was abandoned at the shelter door with his brothers as a puppy. He was 2 months old when we adopted him. I had to do some research in different sources and buy some e-> The book is not considering you're adopting a puppy, but most part of what it shows is still valid. Here is my raw notes about the book: Introduce the dog calmly to everyone in the house</li> Walk the dog at least two times a day, 45 minutes each</li> Remember that you must be the leader always. The dog must be the follower.</li> Be strict with your rules, you can change it later.</li> Your comes and goes must not be a big deal.</li> Audiobooks are good for the dog but you have to do it half an hour before leaving. Audiobooks should be related to a rest time, not departure.</li> Vary your routine when walking, get to know your neighborhood</li> Feed yourself first and then feed your dog, no begging at the dinner table</li> Don't give a threat to your dog before he does the action or you will remove the incentive for the action</li> Don't hug or squeeze your dog, it's not a natural sensation for them</li> Don't give your dog affection when she is already super excited. They will enjoy it more when they are calm</li> Always praise your dog after he did something good not before or without a reason or he will not understand</li> The first days at the new home are the most important for your new dog. He will understand this is a new environment and will follow the rules if you teach in the right way</li> It's possible to change the dog's name. Be consistent and use it many times</li> </ul> Review of Radical Candor: Be a Kickass Boss Without Losing Your Humanity Unknown — Sun, 13 Aug 2017 00:00:00 +0000 Book: Radical Candor: Be a Kickass Boss Without Losing Your Humanity</a> by Kim Malone Scott. Rating: ⭐️⭐️⭐️⭐️. A book every boss should read. It helps to create a culture of giving and receiving honest feedback and create great teams. It has many truths, you will notice many of them if you're working for a big company. You may not agree with some parts of it depending on how you see work and people but if you really care about people careers and the performance of your team it makes a lot of sense. Here are my notes about this book: At apple, we hire people to tell us what to do, not the other way around</li> The manager asked Steve Jobs about how the team should be built and he said that if he already knew that the manager will not be needed</li> The manager role has more to do with persuading than giving orders</li> "babysitting people's emotions" is your job as a manager and it's necessary to be a good boss. It IS real job. Managers should not be complaining about it.</li> When you put people in roles they don't like and are not good at, or when you force people to deliver in unrealistic schedule, you decrease the level of trust</li> Building a trust relationship with your team is vital for every other activity</li> Care personally about people. Give hard feedback when necessary but show them you care about their feelings. "It hurts, I know, but we have to deal with it"</li> A good rule of thumb for any relationship is to read three unimportant things that were not said that day</li> Radical candor praise gives a personal and specific compliment that makes they have your attention and know you're being sincere</li> Criticism is bad in case you don't think about the other person as a human being</li> Be careful when praising, understand all the details. There was a case where the boss decided to praise an employee publicly but forgot so give all the credit. The other employees thought he was taking all the credit for himself</li> To criticism to be effective it's crucial to do it very clearly and to articulate why you're criticizing in details, so people can improve that</li> Praise in public, criticize in private and don't personalize</li> Learn about what motivates each person on your team</li> Rockstars are people who love their jobs and will not get another one if it takes them away from their craft. If you put them in the wrong role, they leave.</li> Superstars need to have challenges to grow constantly Rockstars are just as important as superstars. Stability is just as important as growth.</li> People do a better work when they find that work meaningful</li> Three bricklayers were building the St. Paul cathedral when they were asked about what they were doing. 1: I'm working. 2: I'm building a wall. 3: I'm building a cathedral</li> Be a partner, not an absent manager or micro manager</li> Focus on bad employees instead of focus on the good ones is a bad choice. The improvement of the good employee from good to great will be better than an improvement from bad to mediocre</li> Rockstars usually don't want promotions, be sure to compensate them somehow. Conferences (in case he likes to speak) and so on.</li> Accepting mediocrity is not good to anybody</li> 3 tips to consider when deciding if it's time to fire someone: Did you gave this person radical candor guidance, do you understand the impact of this person's performance on your colleagues, did you ask others for advice</li> Most managers wait for too long to fire people. When they decide to do it, this people performance has been a pain in the ass for the whole team for a while</li> Managers tell many lies to not fire people</li> Lie 1: it will get better. Ask yourself how would it happen.</li> Lie 2: somebody is better than nobody. It's better to have a hole than an asshole. Poor performance actually creates more work.</li> Lie 3: Transfer is the answer. You will not act in good faith doing it</li> Lie 4: it's bad for morale. Don't worry, your team will understand if this person really had a poor performance, you will be helping the team with this decision</li> By firing that person you may help him find another job he excels in. It's not the person that sucks, the job sucks, at least for that person</li> Retaining people doing bad work penalizes people doing good work. Retaining bad bosses is even worst since it has such a bad Impact on people who report to them</li> Sometimes you put a good person in a wrong role. The responsibility for his bad performance is yours.</li> Even in an authoritarian company you will get better results if you lower your power down and work collaboratively</li> Doesn't matter who is right, but how to get it right</li> If your boss is taking a bad decision, it's your responsibility to convince him to change it or he will ask you about it in the future (Steve Jobs did that)</li> Plussing. Instead of criticizing new ideas, try to solve problems with it</li> Bosses should not take decisions alone but listen to the team and guide it</li> Seek facts, not recommendations. The recommendation usually comes with ego.</li> Block time to execute</li> Never try to prove your colleagues values wrong and yours right</li> As a boss exercise your own public criticism. Speak publicly about what you have to improve, this will help others to provide feedback about you</li> Orange feedback box on eBay. The manager answer to all the questions during the meetings and people feel comfortable asking them</li> Don't say: she's really smart. But instead, say: this was the clearest way to show the user problem I ever seen. It will give enough detail about why she's good and in what it applies</li> Let's face it, flat hierarchy is a myth. High hierarchy is an inescapable fact of life (LOL)</li> Categorize your team. You may have rockstars, superstars, people not doing well but with good potential, and people not doing well at all. Work to let Rockstars do their work, motivate superstars, work on peoples growth, and fire those who doesn't have a good perspective to improve</li> If you have more Rockstars than the other teams, it's probably because you're out of sync with your colleagues, not because you have the best team</li> Invest in hiring, it's not easy to fire people</li> Don't make it nearly impossible to fire people or you will get your good employees to do extra work and feel frustrated about it</li> Address performance problems as soon as possible. Try to help the employee to get better and in case it doesn't work, fire him</li> Tolerating bad performance is unfair to people performing well</li> Say thank you. it's a simple gesture and makes a huge difference for the employee</li> Don't announce promotions if it doesn't make sense for the other employees (new responsibilities)</li> There is a chart about micro management vs. Partnership. This article describes it: http://firstround.com/review/warning-this-is-not-your-grandfathers-talent-planning/</a></li> If people are canceling 1-1 frequently is because your partnership is not worth enough</li> If you're not receiving enough criticism, people are not feeling safe sharing it with you</li> Google employees do team update snippets to share with the team</li> Separate decision and debate meetings</li> Meeting agenda should be shared with your team before the meeting</li> People will go to the meeting only if they want or need to be there. People hate to not participate in decision that involve them but they hate attending to meetings irrelevant to them even more</li> Encourage people to switch roles in debate meetings, ego should not be part of it</li> Most parts of the tips in this book consider a really big team</li> Work against meeting proliferation. Remove chairs from meeting rooms, people don't want to stand for a long time.</li> Show you care about the small details and people will start doing the same</li> Encourage people to stop complaining and start helping. Do it yourself too.</li> Clarify everything you say. People will try to use your thoughts to do stuff, be sure they understand correctly.</li> </ul> People management summary: Have clear conversations with each member of your team, create growth management plans once a year, hire the right people, fire the appropriate people, promote the right people, reward people who are doing a great work but shouldn't be promoted. There are great tips here and I mostly agree with them. Stats for Jul, 2017 Unknown — Mon, 07 Aug 2017 00:00:00 +0000 Okay, here we go for the first full month working in my new job. :) Books</h3> </a> This month I read Let My People Go Surfing: The Education of a Reluctant Businessman</a>, which was recommended by the other Doisters</a>. It's a great book by the guy who built the company Patagonia</a>, a bootstrapped company, from scratch. Their way of thinking looks a lot like the way we think at Doist. The second one is Practice Perfect: 42 Rules for Getting Better at Getting Better</a>. I bought this book on Audible daily deal and it surprised me in a good way. It was made for teachers in the beginning but was changed for the general public. You can still feel the education background but it is not a bad thing for me. I found some good strategies my teachers used on me when I was on college. The 7th season of Game of Thrones just started and I decided to read A Game of Thrones, the fist book of A Song of Ice and Fire</a>. After reading it I found the 1st season to be really loyal to the books, which is really nice. If you, like me, enjoys the TV show a lot, I really recommend reading. There are some background and feelings you understand better when reading the books. I hope to start the next one soon. Articles</h3> As usual, I'm using that same export file from Pocket</a> and the same script to calculate the amount of articles I read: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 1044 777</code></pre> It means I have 1044 articles Unread and 777 articles Read. Comparing with my results from the last month (968 unread and 708 read), I got around 8% more unread articles and 9% more read articles. It improved a little bit compared to last month but the unread count is still growing which means I will probably never read many of those articles. =/ Coding</h3> Here goes the charts from Wakatime</a> since the last post. </a> Nothing new here. I have one big peak of almost 7 hours of coding but the rest is stable. I'm still fixing some docs and get all the projects up and running, so I still have a lot of bash</code> and some markdown</code>, but Python</code> is growing. </a> Editors are pretty much the same as last month's. </a> Speaking</h3> Deconstructing the web at Virada Tecnológica</a></li> Building a snake game live and from scratch with Ruby</a> at Guru-SP</a></li> Building CLIs with Golang</a> at The Developers Conference</a></li> Building a game live and from scratch with a browser and a text editor at The Developers Conference</a></li> Your ruby app end to end</a> at The Developers Conference</a></li> Deconstructing the web as a Guest speaker at ELO7 Tech-talks</a></li> </ul> Six presentations in one month. Three of them were in the same day. This month is a personal record for me. 🎉 It was also a huge step towards my goal: </a> Hm... I kinda finished the yearly challenge in July. 😬 Let's see how far I can go! :D Completed tasks</h3> I want to add the amount of tasks completed on Todoist</a>. </a> 554 tasks completed this month. :D I also included my streaks but I think I will have to improve my daily goals, they are too small for me. I have plans to create a better way to extract data from my Todoist account, but I will need some time to work on it. Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 2 days and 18 hours of podcast time, that's a lot. :) I decided to keep a list of the Podcasts and their times as well. </a> Just for the record, this is an "all time list" and I'm tracking time instead of episode which makes short podcasts to not appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Castalio Podcast</a> is going up every month. I was a guest on their podcast</a>, btw! :D Hours working</h3> Here is the data from my time tracking software, Toggl</a>: </a> The above chart is just for my freelance and full-time job. My full-time job is taking all my energy currently and there is not so much time spent working as a freelancer this month. The good part is that I'm working a lot less than the previous months</a> but I'm exhausted in the same way. I've changed the way I'm tracking my projects and now I can see the difference between Deep Work and Shallow work in a better way: </a> It's nice to see that I'm spending 1/3 of my time in Deep Work state. :) There is another chart for my personal projects: </a> It was really hard to work on personal projects this month. This 11 hours was my presentations. I did not consider the whole day speaking at TDC though. :) Here is my data from RescueTime</a>: </a> Another month reaching my productivity goal! :D The only month I reached my goal before joining Doist was March, the month right after my vacations, and now it's the second month in a row. Hope to keep it. Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> According to this data, I can conclude that I had a daily average of 8k steps (249/31), it came back to my previous average. And these are my steps each day: </a> My max distance was 8.3km: </a> Some more weight but not so much: </a> MiFit app interface for sleep data changed a little bit but here is my data for this month: </a> A bit more average sleeping (7h29m for the last month) and a lot more deep sleeping for this month \o/ (last month was 1h04). I bought the Mi band 2, it may have some better monitoring. Let's see how it goes for the next month. :) There's a new feature comparing my stats to the user base: </a> I liked it. :) TV Shows</h3> According to tvshowtime</a> I watched 24 episodes this month. </a> It's a combination of the two seasons of Mr. Robot (really recommended for programmers, BTW), American Gods, and Game of Thrones. I spent 20 hours watching TV this month. Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the amount of words and errors when I'm writting. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. Here are my stats for this month: 51018 words written (34156 last month)</li> 1272 corrections made (634 last month)</li> 10485 unique words (10332 last month)</li> </ul> Since all my work conversations are in English, I have a lot more data here. Less unique words than last month (🤔) but almost 1/3 more words. The bad part is the corrections made, 2x more than last month. =/ Locations</h3> Again, for some reason 1 city is gone from my timeline, that's weird. In the other hand, the amount of places I visited increased by 14. I'm not sure if I can trust on this data from Google Maps. </a> I also decided to add the amount of time spent in a vehicle this month: </a> My presentations increased the time spent on transport, I think. I don't know if I can trust on the distance walking. But still, 16 hours in transport for the whole month! Remote work FTW! Here is a funny metric: </a> The time I have to walk to "get to the moon", LOL. Expenses</h3> My expenses for this month: </a> This chart represents all my income for this month. As predicted last month</a>, I did not receive anything because I was still waiting for the whole process to get my company ready to generate invoices. It took almost two months to complete but I think it's done and I can finally generate new invoices to receive my payment. Most part of my expenses goes to "Despesas do trabalho" (work expenses), since I had to pay a lot of taxes to get my own company ready. It was amazing to find that I still increased my total savings by 0.5% (not so much compared to 5.2% of the last month, but it's positive!) and reached 72.83% of my goal. It happened thanks to my wife supporting our expenses. ❤️ Time to write this blog post</h3> Some people are asking me about how much time it take to collect all the data and write the blog post, so I decided to add this metric. It took 3 hours to write this post 1 hour less than last month but I will still work to improve this time. Conclusion</h3> My new job is taking a lot of my energies. There is a lot of work to do and new stuff to learn. I'm doing my best to make the software I love since 2007 become a great platform to developers build their stuff on top of it. I was not expecting to be so tired at the end of the day, I had to put some personal projects aside for some months. Aside of that, the company and my co-workers are great, I'm really enjoying the experience of building a great product. My Archlinux setup Unknown — Sat, 05 Aug 2017 00:00:00 +0000 I was playing with Archlinux in the last 3 or 4 years and last year I decided to reboot my configuration files and start using Xfce. Talking to Fabio Akita</a> about my Archlinux tunning, I heard that I should be posting about that. That's true, so I decided to start writing it. I wrote in March and it was in draft form since then, so it's time to release it. :) BTW, Fabio already did that</a>, but I will post about my setup anyway. Desktop Environment</h3> I was using Gnome before deciding to reboot my workstation. I met @marcosnils</a> at Gophercon last year and we had some chatting about window managers. I'm a big fan of tiling and was planning to go to a tiling window manager again. The problem with tiling window managers is the amount of configuration you have to create in order to have your laptop in a fully functional mode. I was looking for something between a window manager and a desktop environment, something composable with some support for tiling. And then, he shows me his laptop with Xfce running. That doesn't look like the Xfce I know. It was pretty smooth and with many features I did not know. Then, I decided to give Xfce a try. At first, it was horrible but functional. I could compose its packages to only install what I wanted and almost everything was working out of the box. That's what I was looking for. So it's time for themes, fonts, bars and so on, just to make it beautiful. Here is my results: </a> It looks good to me. :) Xfce has shortcuts to do what I like to do with tiling: vertical and horizontal splits. Here is an example of me writing this blog post on a split screen on my ultrawide monitor: </a> Keyboard shortcuts for different types of screenshots were really useful as well. I did not know this feature, but it was probably my fault. :P Window manager</h3> I was trying different window managers at the time, so I decided to give i3</a> a try. It looks very good if you like (or have the time) to configure and tune it. As I was trying different things, why not to try Wayland as well? So I installed sway</a> instead of i3 to use it with Wayland. It was an interesting test. My configuration files work with i3 and sway currently. I'm usually using Xfce but sometimes I log in with sway to take advantage of the tiling in a different way. Managing configuration files</h3> It's possible to use configuration managers for this task (like Salt</a>, Ansible</a>, Chef solo</a> and so on) but I preferred to use a simpler way. All configurations to recreate this environment is available in my dotfiles repository</a>. It uses a project called dot-install</a> created by Diego Souza</a>. It is a simple bash script that copies the files to the correct places, BOOM, done. I like it. I can create bundles to apply the same configuration files to more than one computer. Some files have to change because of network interface names and so on, but the structure is the same. Kernel</h3> I'm trying different kernels. The first one (and easier) was linux-zen</a>. It is available in the community repository of Archlinux. I really recommend it in case you don't need (or want) to use Docker with support to overlayfs</code>. I was also compiling the rc</code> releases of the Linux kernel whenever possible, so I could try to contribute in case I found something weird, but as it takes a lot of my time, I decided to give it a break for some time. But the best one until now is the linux-ck</a>. It is the Linux kernel with the patches from Con Kolivas</a>. There is a different scheduler running and some other improvements. It was made with desktop performance in mind (just like linux-zen</code>, that uses the same scheduler from linux-ck</code>). linux-ck</code> has its own repo, in case you don't want to compile it yourself from AUR. Just add this line to your pacman.conf: [repo-ck] Server = http://repo-ck.com/$arch</code></pre> Just be aware that the link quality is awful. You have to retry it many times to get the file downloaded. =/ Tunning</h3> There are some good tips to apply on your Archlinux, but I will not just copy & paste it here. Please refer to Fabio post</a>, since I discussed with him about it and we applied almost the same procedure. The I/O related tunning are the most recommended. Package manager</h3> There are some addition package managers available for Archlinux, so you can deal with AUR easily. Fabio uses pacaur</a> but I prefer to use aura-bin</a>. I know guys who prefer to use yaourt</a> but I don't think it has good defaults. Installing it from scratch</h3> I'm that kind of Linux user who likes to install new distributions or rebuild the system from time to time, so I created my own ways to do it faster. I decided to not automate the whole Archlinux installation because it would take more cost than bringing benefit. The partition of the disks and initial installation I do manually and then I use my own scripts and configuration files to get the same environment I had with just a few commands. The first step is to install all packages needed to my day-to-day tasks. For this matter I have this script</a>. It executes many commands to install all packages I need. I run this script</a> every time I decide to reboot my computer. So, instead of running systemctl reboot</code> I run update-and reboot</code> and it reboots with the new packages installed. Conclusion</h3> Since I started used Linux I've gone through Kurumin, Slackware, Ubuntu, and Archlinux. I formatted my laptop many times and kept using Archlinux for the past years, it's the best Linux distribution for my use case. If you're looking for the best cost/benefit for customization and effort doing it, I really recommend Archlinux + Xfce. You will miss some new technologies on the WM side (Wayland...) but it worth the trade-off. Review of Leadership and Self-Deception: Getting Out of the Box Unknown — Thu, 03 Aug 2017 00:00:00 +0000 Book: Leadership and Self-Deception: Getting Out of the Box</a> by The Arbinger Institute. Rating: ⭐️⭐️⭐️. It's a good book. Good information in a good narrative form. This is a short book with an easy to follow narrative about leadership. There are not so many notes about this one, but here they are: See People as people, not objects</li> Self-betrayal is an act in contrary of what I feel I should do for another person. i.e. when you want to hold the door but doesn't</li> When I betray myself I enter in the box and start seeing the world in a way it justifies my self-betrayal, my view of reality becomes distorted</li> With time we tend to carry boxes with us and see ourselves in some self-justifying images we created</li> We don't see people as people but as objects. If they act in ways that don't justify the image we built, we see them as treats. If they act reinforcing the self-justifying image, we see them as allies. If they fail to matter as the self-justifying image we see them as unimportant.</li> When you question your virtues and feelings you can get out of the box.</li> </ul> In summary, this book helps you think about your attitude towards other people and why you have some kinds of feelings in a specific situation. Sometimes it's better to rethink yourself to be able to understand the situation better. I recommend everyone to read this book since it's a small and easy to read. Review of A Game of Thrones (A Song of Ice and Fire, #1) Unknown — Fri, 28 Jul 2017 00:00:00 +0000 Book: A Game of Thrones (A Song of Ice and Fire, #1)</a> by George R.R. Martin. Rating: ⭐️⭐️⭐️⭐️. It's a great book. I know ASOIAF from the TV show "Game of Thrones". This book was the first one I bought at Audible but decided to not start with it (33hs of content). As the 7th season of the TV show started, I decided to gather more information about the whole plot. In case you watched the TV show, you will follow the books easily. The first season of Game of Thrones is loyal to what happened in the book. For me, it was a good reading as I don't remember many things I watched some years ago. I could feel the feelings of some characters in a different way when reading this book. A good example is how Tyrion likes/trust Jon Snow, it was not clear for me in the TV show. The whole plot with Jon Arryn was not so clear for me as well and it was clarified in this book. In summary, it's a great book, with or without the TV show. In case you're following the TV show, it will be a great reading with a lot more details. Review of Practice Perfect: 42 Rules for Getting Better at Getting Better Unknown — Wed, 12 Jul 2017 00:00:00 +0000 Book: Practice Perfect: 42 Rules for Getting Better at Getting Better</a> by Doug Lemov. Rating: ⭐️⭐️⭐️. A good book with lots of advice. The structure is not so good, but it's OK. As the title says, it shows 42 rules to improve yourself and practice in the right way. It an introduction, 42 tips on how to get better at getting better, a conclusion, and the appendices. The structure looks like a to-do list of "rules", so it's not so comfortable to read. The book was made for teachers and then changed to a general-purpose. You still feel many of the examples related to education, but this is not a bad thing IMO. The appendices are really great, I found many of my teachers' techniques there. Here are my raw notes about the book: Practice doesn't make perfect, it makes it permanent. If you're doing something wrong you will just good at doing something in the wrong way</li> To practice is not saying you're bad in what you do, but you can be better in it</li> Plan everything before practicing. Use every minute in the right way.</li> What looks like talent is actually a lot of right practice</li> To improve their answers to students, two teachers practice students' questions for 10 minutes each day for some weeks. Practicing the right thing.</li> There are countries where people are better at sports, but they had a good coach since the beginning and have been practicing it since forever.</li> If errors are persistent in your training, reduce them to make it simple. You want the participants to complete the fastest possible light version of your training in the right way and then you can increase the complexity</li> Practice the 20% (Pareto)</li> Plan before doing. Find your 20% and plan on practicing it.</li> You don't have to be aware of your knowledge to use it. You learn by doing, even if you don't remember it</li> Automate skills to unlock creativity. When you know how to do a task without thinking about it (just like system 1 of Thinking, Fast and Slow</a>) you have time to think creatively about what to do differently.</li> Replace the vague idea of purpose with a managed and direct goal. Instead of "be a good basketball player", go for "Score 70% of my three-point shots in a match".</li> Find and train areas of talent and areas of weakness. Doing that in-group is even better, as one person weakness may be the other's talent</li> Focus on correcting errors, not critique</li> Isolate the skills. Practice in chunks</li> Name it. Define names for the important skills and guarantee everyone is on the same page</li> Matching skills. Make your practice environment similar to the game field. Practice like you are in the game, with the same conditions.</li> Make a plan, plan to the last minute, video tape and watch your practicing sessions</li> Before modeling (or teaching) tell them what to look for. When you're explaining something, students will better understand what you're trying to say.</li> Make models believable. Model in the context of the students</li> When creating a model for someone you're coaching, show them what you made to get to this point, not just the instructions you are using.</li> Feedback is great, use it and give some.</li> Apply the feedback first, then reflect about it</li> If you want to change behavior, shorten the feedback loop. Give feedback sooner</li> Give feedback right away, even if it's imperfect. The speed of consequence beats the strength of consequence almost every time.</li> A simple change implemented right away is simpler than rewiring the steel</li> If you really care about something, you give it constructive feedback. If you don't care about something, you give it only positive feedback</li> Ask people to summarize your feedback, so you know they understood what you mean</li> Normalize error. Don't punish people for their mistakes, it will create a culture of extreme caution or fear.</li> Failure is normal, not an indication of the lack of skill</li> Failure rate and level of skills are Independent variables</li> Expose your weakness to your peers so they can help you improve</li> Challenge people to do things and make mistakes, then correct them before they become too ingrained</li> Practice should not be punishment, make it fun</li> Just coach during the game, don't teach. Use small signals instead of full lessons</li> As a leader, state feedback not just as advice but as something needed for progress</li> Collect data on specific skills to work on. e.g. how much a sales strategy resulted in success</li> Look for how great people on your field practice in environments similar to yours</li> </ul> Stats for Jun, 2017 Unknown — Mon, 10 Jul 2017 00:00:00 +0000 I'm ready to review my stats for June and share them with you! Are you? Hope so! :D Books</h3> </a> Last month I read Deep Work</a> again because I was preparing to work for a new company. The new company is Doist</a>, but this is a topic for a another post. It proved to be a great asset, as they also recommend reading it. From their reading list I also took The score takes care of itself</a> and Start with Why</a>. Both are great books on how to think your products and leadership, highly recommended! Before joining I read The secrets of story</a>, a great book on how to write novels and keep your reader turning pages. There are many great tips there, I really recommend if you want to write a novel someday. The other one is Louder than words</a>. It's all about how we deal with meaning. It was interesting to think about meaning as a concept beyond words, for computer scientists, think about words as being pointers to a meaning. :) That's it, 4 books in a month, I'm proud of myself :P Articles</h3> As usual, I'm using that same export file from Pocket</a> and the same script to calculate the amount of articles I read: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 968 708</code></pre> It means I have 968 articles Unread and 708 articles Read. Comparing with my results from the last month (861 unread and 662 read), I got around 11% more unread articles and only 6.5% more read articles. It was a lot more unread articles and not so much read ones. I will have to work on it again. Coding</h3> Here goes the charts from Wakatime</a> since the last post. </a> Looks like my coding productivity is back to normal. Hope to improve my deep working this month. Much of what I did was related to improve static pages and documentation projects, so I have a lot of bash</code> and Markdown</code> as most used languages. </a> Editors are pretty much the same as last month's. </a> Speaking</h3> HTML5 Game development</a> at Impacta Tecnologia</a>.</li> Guru-SP representation on a panel discussing communities</a> at 19o Encontro Locaweb</a>.</li> </ul> Here is the current status of my goal for presentations this month: </a> A good progress this month and I have three more scheduled for next month. Go go go! Podcasts</h3> Here is my Podcast Addict</a> stats: </a> 1 day and 23 hours of podcast time. It's a lot less than last month, but that's common as I listened to many audiobooks instead. I decided to keep a list of the Podcasts and their times as well. </a> Just for the record, this is an "all time list" and I'm tracking time instead of episode which makes short podcasts to not appear as "most listened" ones. I listen to CBN podcasts</a> almost every day, but they are just some minutes long. Hours working</h3> Here is the data from my time tracking software, Toggl</a>: </a> The above chart is just for my freelance and full-time job. It's less than what I'm used to see but it's OK since I left my previous job and took some days "off" (not exactly off, but that's it). There is another chart for my personal projects: </a> Almost 4x more than April. :D Here is my data from RescueTime</a>: </a> For the first time (I think...) I reached my goal! New job + deep work FTW. Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> According to this data, I can conclude that I had a daily average of 10.6k steps (318/30), a lot more than next month (it was 8.3k) \o/. And these are my steps each day: </a> My max distance was 11.7km: </a> My weight is almost the same: </a> My sleep data: </a> Less average sleeping and less deep sleeping for this month. It's not so much (around 10min avg for both), but I should keep an eye on it. TV Shows</h3> According to tvshowtime</a> I watched 35 episodes this month. </a> It's a combination of Better call saul, two seasons of Sense 8, and Mr. Robot (finally! :D). It's a bit confusing to calculate how many days I spent on TV shows this month, but I now reached the mark of 1 month of time spent (or wasted, pick your side) watching TV. =/ Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the amount of words and errors when I'm writting. Unfortunately, they only send weekly emails, but I will try to keep this metric for a while. My stats for this month: 34156 words written (26914 last month)</li> 634 corrections made (243 last month)</li> 10332 unique words (11478 last month)</li> </ul> More than 8k words written compared to last month but also almost 3x more corrections made :(. Unique words are less than next month but not so much. Locations</h3> For some reason 1 country and 1 city is gone from my timeline, maybe I did some cleanup but didn't remember. In the other hand, the amount of places I visited increased by 55! I'm not sure why that happened, since I did not traveled this month. It was probably some cleanup made by Google Maps folks. </a> I also decided to add the amount of time spent in a vehicle this month: </a> 9 hours in the whole month! In contrast, I walked 111km, which is probably part of my daily dog walking / Gym routine. Remote work FTW! Expenses</h3> My expenses for this month: </a> This chart represents a small portion of 17% of net income, the rest is being invested. Yeah, but again this was atypical month. I know it's being repetitive already but as I'm changing jobs, I received some money related to Brazilian work law stuff (yeah, it's complicated) and almost everything was invested. Part of this money will be used in the next month, because I will not be able to generate invoices yet, thanks to the very slow Brazilian processes to have your own company. I had to change my portfolio because of this changes in my professional life and also because of the current state of economics and politics in Brazil. This month I increased my total savings by 5.2% and reached 72.46% of my goal. Time to write this blog post</h3> Some people are asking me about how much time it take to collect all the data and write the blog post, so I decided to add this metric. It took 4 hours and 03 minutes to write this post Almost the double comparing to last month. As I had to change a lot of things on my investment portfolio, it took some time to organize everything again. Conclusion</h3> I feel great this month. :) The new job is amazing and I can focus on my deep working routine to actually do real stuff. I'm still getting used to the new workflow and software I have to support, but it's being an awesome experience. Hope to have more good news next month. Review of Let My People Go Surfing: The Education of a Reluctant Businessman Unknown — Thu, 06 Jul 2017 00:00:00 +0000 Book: Let My People Go Surfing: The Education of a Reluctant Businessman</a> by Yvon Chouinard. Rating: ⭐️⭐️⭐️⭐️. It was 3 stars until 70% of the book but the ending deserves 4. This book is the story of Patagonia</a> and how its founders deal with business, people, and the environment. Their way of life resonates a lot with what I think is a good way to live. Maintain a sustainable business, hire people you trust and give them enough freedom to live a good life while giving their best to make the company grow, thinking about the environment, grow only when you have to grow (to supply your demand), live a minimalistic life, and so many other stuff. Here is my raw notes about the book: You don't make it perfect when you add everything you can, but when you remove everything possible and keep it to the bare minimum</li> Employ people who share the fundamental values of the corporation while representing cultural and ethical diversity</li> The quality of the product is related to its use</li> Provide ways to fix the product because each new product manufacturing is a piece of the environment that goes away</li> People say they can't contact someone but this is a dishonest answer. They don't want to do it or it doesn't have a high priority for them</li> Deliver what your client wants when he wants it. If you don't do that he will look for a company that does. After he does that it's hard to get him again.</li> Expect your supplier to deliver on schedule, but you have to do the same</li> American companies fail in the Japanese market because they try to do business by the book.</li> Show people who you are as a company, not a fictional character. There are companies creating fictional characters for what they want people to see, not the real truth. It's easier to show the real company if you really live what you say.</li> Profits happen when you do everything right. It's a consequence.</li> Grow only at a natural rate. If there is no product in the stock, it means we have to produce more, and its natural growth</li> Don't create an artificial advertisement for your goods just to increase the demand. Create a product that your clients really need. We want customers that need our product, not just desire it.</li> We don't want to be a big company, we want to be the best company.</li> Hire many as people as possible who use your product and like it, they will make it even better</li> I never saw a company that wants to build the best product ever when people who work there are not passionate about it</li> We prefer to hire from our network of friends and business associates. We don't want stars seeking special treatment, we look for the best person for the job, even if it means keeping a position open for a long time.</li> It's easier to teach the work to people who have your culture and like your product, but it's really hard to teach culture to high-skilled people</li> Let my people go surfing and believe they will not abuse their benefits. Everyone can make their own work time. Work whenever you want and feel more productive and enjoy your life.</li> We don't want soldiers who obey orders, we want people who question every decision and wants to make the best for the product</li> Managers must be always available for those who report to them. Have a commonplace for people to exchange ideas (cafeteria)</li> The answer to global environmental change is action. Don't wait for others or for the technology to solve the problem, act now</li> No businessman change aggressively one department without thinking on the rest of the company, but that's what is happening to the environment</li> A company that builds landmines but doesn't know what they do should go to a country where they are a problem to locals, so they can see what their product does to the people. All companies should do the same with the environment.</li> Evil is the absence of good. If you can do good and you're doing nothing, you are doing evil.</li> The more you know, the less you need</li> </ul> Review of The Score Takes Care of Itself: My Philosophy of Leadership Unknown — Thu, 29 Jun 2017 00:00:00 +0000 Book: The Score Takes Care of Itself: My Philosophy of Leadership</a> by Bill Walsh. Rating: ⭐️⭐️⭐️⭐️. It's a great book on leadership. I confess that I was really bored in the first 15% of the book. The beginning is boring for those who don't give a fck about football but keep reading, it worth the journey. Bill Walsh took the San Francisco 49ers from a really bad performance (2 wins/14 losses) to an amazing one (13 win/3 losses) 2 years later. He applied his organizational philosophy to the whole organization and this is what this book is about, how he managed to do that, and how it works. Here are my raw notes about the book: People are the most important part of an organization</li> There is no method that guarantees a victory, but there are things to do to increase the probability of success</li> Expect defeat.

Rating: ⭐️⭐️⭐️⭐️. I always thought we must first have a reason to create something and this book shows some companies that are famous for doing that and how they did it. Here are some notes about it: Most of what we have now is marketing by manipulation</li> Fear is the most powerful manipulation of all. A good example is the insurance commercials talking about guns or heart attacks.</li> Peer pressure. This product is recommended by 80% of the specialists in the field. If specialists use it, it's probably good for you.</li> It's not because it works that it's good. It works for many situations, but is it good for you and what you want to do?</li> What, how, and why. What is easy to answer. How shows the way you work but why says the reason behind your actions, what do you want to achieve, and why should people care. Money is not an answer, it's a consequence</li> The great leaders of our time think from the inside out of the golden circle, from why to what. The first thing is to tell why are you doing something.</li> Don't sell what you do, sell why you do it.</li> If you don't know the why, you will not know the how</li> Your why and the clients why should be the same</li> Why is just a belief, how is the action that makes this belief happen</li> Business is just like dating, you may impress on the first date, but if you don't build a relationship (why) it will not happen again</li> We do better when the culture fits</li> The goal is not to hire people with the skillset you need but people who believe in what you believe</li> When hiring, how do you know if someone is passionate about something? Everyone is passionate, but you have to understand if they have the same why as you.</li> Dream teams are not so dreaming. When they are together, they work for themselves, not for the whole -- 💭 had to emphasize that, been there.</li> Great leaders are respected both above and below the hierarchy</li> The optimists who change the world</li> "Why" people need "how" people. How types don't change the world but make things happen.</li> People have Apple or Harley Davidson logo tattooed on their body. Why? Because it's a symbol, of a way of life, not just a logo. (lifestyle marketing)</li> Be careful to not assume wrong things and take actions on top of it, get good data for your assumptions</li> Aspiration. Many people are aspired in the beginning of the year to go to the gym but very few keep the routine. You can aspire, it's good, but keep it.</li> Until now, manipulation is the law, but there is an alternative.</li> Good leaders see what others can't see</li> You don't hire the skills, you hire the attitude. Skills you can teach.</li> How do you know if these people are passionate about something? Everyone is passionate, but yiu have to understand if they have the same why as you.</li> You don't hire skilled people and motivate them, you hire motivated people and train their skills</li> When you pay a lot to "get the best talent" they will not show up for the why but because of the money</li> There are innovators, early adopters, and the mass. The mass doesn't want to test things that are not established</li> Energy motivates but charisma inspires</li> The optimists who change the world</li> Why people need how people. How types don't change the world but make things happen</li> EFE works to give a feel of opportunity to people, with mindset and knowledge</li> People don't do things for a common reason, they do that for themselves. You must align their why with your goal</li> Make your logo a symbol, not just a logo. People have Apple or Harley Davidson logo tattooed on their bodies. Why? Because it's a symbol, of a way of life, not just a logo</li> Gates fail when he left Microsoft. Ballmer doesn't have the same why, he's a business man. Gates inspire people because of what he did.</li> </ul> 7 anos de Locaweb e a saida Unknown — Wed, 14 Jun 2017 11:26:10 -0300 TL;DR: Esse mês eu completaria 7 anos trabalhando para a Locaweb, mas decidi sair no dia 2 de junho. Nada demais, só procurando coisas diferentes Eu entrei na Locaweb em Junho de 2010. Na época o Fabio Kung</a> entrou em contato comigo perguntando se eu queria me juntar a equipe de Cloud Computing. A equipe de Cloud</h2> Depois de uma conversa com ele e com outro gestor, eu descobri que era exatamente o que eu queria fazer, trabalhar com Ruby e infraestrutura, duas coisas que eu gostava muito. Fui aprovado no processo seletivo e comecei na equipe que tinha várias pessoas legais. Entre eles estavam algumas pessoas conhecidas na comunidade de Software brasileira, principalmente na comunidade Ruby, como o Nando Vieira</a>, o Fabio Kung</a>, o Rafael Rosa</a> e mais algumas pessoas que manjam bastante mas não costumam aparecer tanto. A equipe era composta de 50% de desenvolvedores e 50% de sysadmins. Nessa equipe eu tive que lidar com várias linguagens. Ruby era minha linguagem principal, mas sempre tinha algumas linguagens diferentes para mexer. Alterei código Python, ASP, ASP.net e Perl. Foi uma experiência fantástica, aprendi bastante e mexi com coisas que não eram tão comuns para a galera que estava trabalhando com Ruby e/ou Rails na época. Atualmente, 5 pessoas da equipe de Cloud estão trabalhando em empresas grandes fora do país. Não vou focar em datas, se quiser ver as datas, dê uma olhada no meu Linkedin</a> que tem o tempo que eu fiquei em cada cargo/equipe. A equipe de IaaS</h2> Depois de um tempo a equipe de Cloud virou parte da equipe de IaaS. Além de manter a infraestrutura/aplicação de cloud, nós tinhamos outras responsabilidades. Nessa equipe nós também mantinhamos as aplicações de servidores dedicados, load balancer, backup e o painel unificado para todas essas funcionalidades. Nessa época estavamos mais juntos com a equipe que estava fazendo melhorias e automatização na infraestrutura. Partipei do projeto Openstack</a> enquanto desenvolviamos algumas funcionalidades no Quantum (agora Neutron</a>) e cheguei a participar da Openstack Design Summit em San Francisco</a>. Infelizmente, pouco código que fizemos voltou para o trunk, mas foi divertido fazer parte do projeto. Nessa época eu comecei a organizar as Tech-talks internas, toda quinta-feira tinhamos pessoas apresentando coisas técnicas e legais dentro da empresa. Foi um grande desafio manter isso funcionando por quase 2 anos, religiosamente toda quinta-feira sem muito suporte. Usei bastante Ruby e Python nessa época. Das pessoas que trabalharam nessa equipe, 3 estão trabalhando para fora do país de alguma forma. Duas delas se mudaram para outro país e uma trabalha remotamente para uma empresa de fora. Também nessa época eu desenvolvi um projeto que em menos de 1 ano economizou mais de 1 milhão em gastos. Havia uma possibilidade de otimização em outra equipe, mas ninguém tinha tempo para atacar o problema. Eu pensei na solução durante o fim de semana e tirei 2 dias para atacar o problema e mostrar uma POC totalmente funcional para o CTO. Com isso consegui meu tempo para melhorar o projeto e acompanhar os ganhos durante os próximos meses. Não tinha nada de científico no projeto, era apenas Ruby, Threads, média simples (na primeira versão), chamadas para algumas APIs internas para conseguir os dados necessários e uma interface JSON. Depois desse projeto eu mudei de equipe. A equipe de Infra-dev</h2> A equipe de infra-dev era composta por cerca de 8 pessoas bem experientes e de áreas diferentes. Não funcionava muito bem como um time, mas atacava diversos projetos ao mesmo tempo. Nessa equipe nós trabalhavamos em um nível abaixo do que eu trabalhava em IaaS. Enquanto IaaS consumia APIs e entregava os produtos para os clientes, Infra-dev fazia essas APIs e garantia que os assets estavam bem usados. Basicamente trabalhavamos com código voltado para infraestrutura e automação. Além disso, trabalhavamos em melhorar as ferramentas para os desenvolvedores. Saimos do Gitorious interno e migramos para o Gitlab, entregamos libs de métricas, tinhamos um sistema de métricas desenvolvido internamente e cuidavamos de alguns sistemas responsáveis por catálogo e instalação de maquinas. Nessa época eu tive a oportunidade de participar da OSCON</a> em Portland, OR. Foi uma experiência fantástica, com certeza uma das melhores conferências que eu já fui. Nessa equipe tive contato com várias linguagens de programação. Mexi com Ruby, Python, C, Go, Javascript e tive contato com Haskell e clojure. Conheci pessoas que tinham um conhecimento enorme e uma forma bem legal de lidar com problemas técnicos, foi uma experiência bem interessante. Das 8 pessoas que trabalharam comigo nessa equipe, 2 delas estão trabalhando fora do país. Depois de um tempo a equipe foi dividida para atacar coisas diferentes. Eu fiquei mais próximo do pessoal de desenvolvimento do que do pessoal de infraestrutura e propus a criação da equipe de ferramentas. A equipe de Ferramentas</h2> Há muito tempo eu via a necessidade de melhorar a produtividade do time de desenvolvimento (cerca de 100 pessoas) e resolver alguns problemas grandes e latentes que ninguém teria tempo para resolver. O gerente da época gostou da ideia e começamos a equipe com apenas duas pessoas, que depois de alguns meses ganhou mais uma pessoa. Essa também foi uma equipe fantástica, começamos com duas pessoas que tinha no mínimo 5 anos de empresa. Já sabiamos quais eram os problemas que nos atrapalhavam, mas para ter certeza conversamos com pessoas várias equipes para confirmar. Listamos os problemas e começamos os trabalhos. Sou bem orgulhoso das coisas que criamos nessa equipe, acho que conseguimos atingir o nível técnico que queríamos. :) Tinhamos sistemas e ferramentas feitos com Elixir, Ruby e Go. The Good, the Bad and the Ugly</h2> Durante o tempo que eu trabalhei na Locaweb eu tive a chance de visitar 9 estados brasileiros, 2 estados americanos e 1 país europeu para conferências, com as despesas pagas pela empresa. Meu salário mais do que triplicou durante esses 7 anos. Consegui lidar com vários problemas técnicos interessantes e um monte de linguagens de programação. É claro que essas coisas não vem de graça. Para visitar todos esses lugares eu corri atrás e criei conteúdo para apresentar e submeter para conferências, aproveitando que a empresa apoiava tais atividades. Nos eventos que fui como participante, é porque eu estava capacitado para conhecer as coisas ou participar de discussões, além é claro, de repassar o conhecimento na volta. Eu entrei ganhando relativamente pouco na época, mas para que o meu salário chegasse ao nível que chegou durante esses 7 anos, eu tive que mostrar o meu valor e me motivar a cada dia. Empresas grandes como a Locaweb (e outras) tem bastante espaço para crescer, se você souber procurar. Mas tem bastante espaço para ficar acomodado também, depende do caminho que você escolhe para você. Lidei com vários problemas técnicos interessantes porque eu sempre estava buscando por eles. Eu poderia estar fazendo apenas aplicações Ruby/Rails e pegando os "problemas mais fáceis" ao invés disso. Fora isso, teve os momentos de desconstração pós horário ou nos intervalos. Conheci uns 3 ou 4 jogos de tabuleiro novos depois do horário, me fizeram comprar mais cartas para incrementar meu deck de Magic the Gathering para jogar contra algumas pessoas, perdi feio em 2 campeonatos de Street Fighter IV, perdi no campeonato de ping-pong e rompi o ligamento do ombro esquerdo jogando basquete com alguns colegas de trabalho na quadra próxima durante o horário de almoço. Acho que esportes não são a minha praia. :P Apesar desse monte de coisas legais, a Locaweb, como todas as outras empresas, não é perfeita. É uma empresa grande, que já foi familiar, que tem quase 20 anos de história e que já teve (não sei como está hoje) mais de 1000 funcionários. Trabalhar em uma empresa com essas características e achar que pode fazer coisas que você faz em uma startup é ser um pouco ingênuo. Para trabalhar em empresas grandes, você tem que estar preparado para lidar com burocracia desnecessária e politica, e a Locaweb não é exceção. Lá não é tão burocrático como outras empresas que vemos por aí, onde você sabe que nem vale a pena tentar enfrentar o que está ruim. Eles ficam num nível que parece que a burocracia pode ser vencida se algumas pessoas decidirem ter um pensamento mais "pra frente". Como a amostragem é grande, você encontra de tudo. Pessoas muito boas subvalorizadas, pessoas ruins supervalorizadas, pessoas boas que se encostaram com o passar do tempo, pessoas em cargos errados e outras coisas. Nada muito diferente de outras empresas grandes por aí. A parte técnica sempre foi resolvida, esses tipos de problemas o pessoal tira "de letra". ;) Conclusão</h2> Eu e a empresa estamos em vibes diferentes no momento e eu decidi tentar outras coisas, mas é uma empresa fantástica que eu com certeza trabalharia novamente. Eu diria, assim como vários amigos que trabalharam comigo por lá dizem, que foi a melhor empresa que eu já trabalhei. Nunca tinha ficado mais de 1 ano e meio em uma empresa e fiquei 7 anos lá (uma média de 1 ano e 8 meses por equipe). Sobre mim? Começo em outra empresa na semana que vem, provavelmente comentarei mais sobre isso em breve. :) Review of The Secrets of Story: Innovative Tools for Perfecting Your Fiction and Captivating Readers Unknown — Wed, 14 Jun 2017 00:00:00 +0000 Book: The Secrets of Story: Innovative Tools for Perfecting Your Fiction and Captivating Readers</a> by Matt Bird. Rating: ⭐️⭐️⭐️⭐️. A great book on how to write books. 4.5 stars. The book goes through many problems and misconceptions behind writing a fiction book. In the book blog, you can find a big checklist with many questions your book has to answer: http://www.secretsofstory.com/2014/09/the-ultimate-story-checklist-raising.html</a> There are many examples around each of these topics throughout the book. Here are some notes: When you're telling a story, you are that guy in the airplane that tries to talk to you before you plug your earbuds. Nobody wants to hear you, you have to prove your value.</li> The reader will choose just one character of your story to be his/her hero</li> The audience will put their emotions into your "hero" and with that comes a lot of expectation. Don't disappoint your readers. You feel betrayed when you trust someone and he doesn't meet your expectations.</li> The audience doesn't have to sympathize with your hero, but they have to emphasize.</li> Make your hero misunderstood to create identification with your readers.</li> Your story is not about your hero's life it's about your hero's problem. Everything you're describing must be related to the problem, not just the character. So, don't start with the protagonist waking up in the morning. Start with his problem.</li> People don't like to break expectation, they like to be right on their hypothesis</li> Break expectation too much makes people to not connect with the characters</li> Create a backstory for your character but do not use it to show who your character is, you have to build his story throughout the front story</li> People prefer stories about transformation. Your hero has to transform itself and evolve</li> You can't say that your hero is doing what he's doing for self-realization, you have to show it. (yes, that old rule: show, don't tell)</li> When an important conversation will take place put objects in the hands of your character. Cafés are bad places for conversation, you don't have many objects to interact with and it's difficult to show emotions</li> If an action will affect different things, you have to connect these things to your audience. A nuclear bomb will kill a lot of people, but your audience doesn't know these people, you have to connect them. If one character has a child out there, the audience will connect to it.</li> Don't force your characters to follow the plot by doing stupid things. Trap your characters into dramatic situations and then let them fight the way out of it.</li> Remove what is behind the coma: Did you know that? Yes, I'm so sorry. To: Did you know that? I'm so sorry.</li> Answer the dramatic question at the end of your story. Which is your dramatic question?</li> A good way to end a story without killing the villain is to make the village turns into a greater evil. (Darth Vader and the Emperor)</li> If one people complain about something in a review, it may be just a personal opinion. If two people comment on the same thing, it may be a general opinion and you must consider changing it.</li> Don't just revise, rewrite. It's part of the job. The second and third drafts must be an almost complete rewrite of the first one, and then you can start tweaking it</li> Be ok with teleportation. Your character doesn't need to follow the space-time rules, just the concept. Move them easily through places, just let the reader know what is happening</li> That's it. I recommend you to look to the checklist, if you know how to answer most of those questions the book may not be good for you. But if you don't know how to answer them, I highly recommend you to read the books to see the examples the author mentions for each of those topics.</li> </ul> That's it. I recommend you to look to the checklist, if you know how to answer most of those questions the book may not be good for you.

Wordpress to Middleman, to Hugo using github-pages and HTTPS Unknown — Tue, 13 Jun 2017 13:54:49 -0300 Yes, it was a journey. I decided to chance my blog engine again. But this time I decided to post about the whole transition, since I started my blog, back in 2008</a>. I needed a blog at the time but could not spend time creating something, I just wanted to "buy a blog" and write. Dreamhost was an awesome service for that. In one hour I bought a domain, installed a Wordpress via one click install and set up my own email via Google apps (at the time it was free). Wordpress is a good blog engine, it just works. You have to keep it updated because of security risks, but it works. I wrote some plugins and customized themes during the years I used it and it worked just fine. Please, don't say bad things about Wordpress, it solved more problems and is great for so many people. :) After some years I decided it was time to cancel my Dreamhost account. I had just some small websites there and all of them could become static pages. That's what I did. All my website were converted to static web pages and migrated to Github pages, including this blog. But let's focus on this blog for a while. Migrating from Wordpress to Middleman</h2> I was already using markdown for my blog posts because I was posting from Vim using Vimpress</a>. So I had to convert all other posts from HTML to Markdown. My old layout was not good anymore. I was looking for something responsive and used the migration to get the courage to change the layout as well. I bought a Wordpress layout and converted it to .erb</code> for Middleman. I was using Wordpress comment system and I decided to not migrate to Disqus. Today I know that I could do that, but at the time I decided to just abandon the old comments. But I wanted to keep the names of everyone that wrote a comment in the article. Most of the migration was done by a Ruby script</a> that I created. These are the steps needed: Download an .xml</code> backup of your Wordpress posts with comments</li> Change the script to use the correct file name and blacklist comments</li> Run the script</li> </ul> The script will convert all posts from HTML to Markdown and create individual files for every post, following the middleman style. You just have to check every post and fix images. In my case, it was harder than that because I was creating a blog from scratch but using the same content. But at the end, it worth the work. Migrating from Middleman to Hugo</h2> For some reason, I decided to not post about my blog engine change this year. I was using middleman</a> since May 2015</a>, but decided to change to Hugo</a>. I promised myself that I would not change my blog engine to Hugo just because it looks cool. And then Middleman started to work weird, sometimes the middleman serve</code> serves my content as plain text instead of HTML. It was hard to try it locally before publishing. It was everything I needed to try a new blog engine (haha). This migration was simpler. I just had to understand how Hugo works and how the template language works. To convert middleman format to Hugo I used a big sed</code> command that I can't reproduce anymore. haha As usual, I used the migration as an excuse to do more things. Since 2008 I change my URLs layout many times. So, I used Google Analytics to get these old URLs and added them as aliases</a> in Hugo. The old URLs now work with the current blog. Some advantages of Hugo: It's just a binary, I don't have to install anything beyond that. (aura -S hugo-bin</code> :D)</li> It builds really fast, it's not fair to compare with middleman (Go X Ruby)</li> There are some great features, like aliases</li> I really like the live-reloading by default</li> </ul> HTTPS</h2> I was missing the HTTPS feature, but it was not possible to use it when using Github-pages, at least not for custom domains. After reading this post (pt-BR)</a> I found that it would be possible to use HTTPS, even in Github-pages, and for free. The solution: Cloudflare</a>! Cloudflare has a free plan that is sufficient for many blogs out there. You just have to create your account and point your ns</code> entries to their servers. By doing that you can even use HSTS! :D Conclusion</h2> I'm really happy with the current setting. Hugo is a great platform</li> Github is fast, simple and free</li> My new layout has the features I need</li> It's easy to change</li> </ul> Static pages are the future... again... haha Stats for May, 2017 Unknown — Wed, 07 Jun 2017 00:00:00 +0000 Here we go again for my stats for the last month. :) Books</h3> </a> I will start a in a new company this month, so I decided to re-read Deep Work</a> (I really recommend this one). This book is just great for everyone who wants to focus and do the hard work. It has everything to do with my new work schedule. The book about Elon Musk</a> was a good reading as well, this guy has some great ideas. Articles</h3> I'm using the same export file from Pocket</a> and the same script to calculate the amount of articles I read: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 861 662</code></pre> It means I have 861 articles Unread and 662 articles Read. Comparing with my results from the last month, I got almost 5% more unread articles, but this time I got almost 10% more read articles (double of the last month's). It happened because I took some hours to read the some articles of my Pocket account. Coding</h3> Here goes the charts from Wakatime</a> since the last post. </a> The chart for this month is really better than last month's but still less than what I was expecting. Back to Ruby this month, there were some old Rails projects to work. But most of my time was spent on the Terminal, for a change. </a> Emacs is my main editor and there was almost no Vim this month. But Bash</a> is taking more than 40% of my time. </a> Speaking</h3> Apache Mesos as a tool</a> at TDC Florianópolis</a>.</li> A ruby application end to end</a> at TDC Florianópolis</a>.</li> Tech-talk at Locaweb</a>. It was a Tech-talk about TDC Florianópolis</a>. As usual, every time I go to a conference I schedule a talk to explore the content I saw there. This was no different. :)</li> Deconstructing the web</a> at BioRitmo tech-talks.</li> </ul> Here is my current status of presentations this month: </a> I'm on-track again! :) Podcasts</h3> Here is my Podcast Addict</a> stats: </a> It was the equivalent to 3 days and 9 hours of podcast time (I tend to speed up all my podcasts, so I don't know how much time it took for real). It's almost 15 hours more than April. I decided to keep a list of the Podcasts and their times as well. </a> Just for the record, this is an "all time list". :) Hours working</h3> Here is the data from my time tracking software, Toggl</a>: </a> The above chart is just for my freelance and full-time job. There is another chart for my personal projects: </a> My data from RescueTime</a> is better than last month but not good enough yet: </a> Maybe next month I will reach the target. Physical activity</h3> I'm using my Mi band data to calculate my average steps: </a> According to this data, I can conclude that I had a daily average of 8.3k steps (260/31). And these are my steps each day: </a> The peak was in a nice Sunday when I met some friends to chit-chat in a local park. It was just 3 of us talking and walking around the park. My max distance was 12.7km walking in that same Sunday: </a> I lost some kg this month. This is a good sign, I think. </a> This month I slept less but with more deep sleep: </a> I think this is a good sign as well. I want to sleep better, not sleep more. TV Shows</h3> According to tvshowtime</a> I watched 39 episodes this month. </a> More than 18 of them is still part of our (my wife and me) How I met your mother marathon. The other episodes are a combination of Better call saul, 13 reasons why, and Sense 8. I spent almost 1 day of my life watching TV Series this month. Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the amount of words and errors when I'm writting. Unfortunately, they only send weekly emails, I don't know if I will keep these metrics because it take some time to build it. Anyways, here is the data for this month: 26914 words written</li> 243 corrections made</li> 11478 unique words</li> </ul> I decided to remove my "common mistakes" from this report because the data seems to be not reliable. Locations</h3> This month I visited 18 new places (the last month were 338 places) and 1 new city: </a> Expenses</h3> My expenses for this month: </a> This chart represent only 47% of net income, the rest is being invested. Just like last month, this was atypical as well. Last month I received the money related to my freelance work on January and March and now I had to pay the taxes related to it. This month increased my total savings by 1%. I have 68.83% of my goal. Time to write this blog post</h3> Some people are asking me about how much time it take to collect all the data and write the blog post, so I decided to add this metric. I'm spending almost no time to collect the data, most part of it is automatic. The services that require manual interaction are already part of my day-to-day life, so I'm not tracking it. It took 2 hours and 30 minutes to write this post Conclusion</h3> This month was better than the last one. It was not so good as I expected because I had to do some exams to be sure I'm OK and I was also changing jobs. I was working for the same company for the last 7 years and decide to try something else, but this is a subject for a different post. ;) I got two weeks to "relax" (cof... work on some personal projects... cof), so I don't know exactly how the next month will be. Let's wait for the next post! :) Review of Louder Than Words: The New Science of How the Mind Makes Meaning Unknown — Mon, 05 Jun 2017 00:00:00 +0000 Book: Louder Than Words: The New Science of How the Mind Makes Meaning</a> by Benjamin K. Bergen. Rating: ⭐️⭐️⭐️. A good book, but maybe it's not for me. I really like books that have a lot of research behind it, this is one of them. For almost every assumption made, the author reveals research done to support his point. This book made me realize that our words do not give meaning to something. For example, the word "pen" is not the meaning of something that writes with ink, it is just a pointer to that meaning. The meaning is the source that we generate. When you learn a different language, you're pointing to this same meaning. Sometimes this meaning can be made of sounds, smells, movements, and so on. Meaning is a different thing for different people. The thing with simulation is really interesting. We use the same part of the brain to do an action and to simulate it. The same area of the brain activates for executing an action, thinking about an action, and understanding a word about an action. Expertise affects how people understand words. It may look obvious but sometimes we forget that some concepts that are obvious to us are not obvious to someone else. This book also comments about a TMS</a> and how it may interfere with how we speak. But the interesting thing about this experiment is that it also interferes with how we talk to ourselves when stimulating the "talking area" of the brain. That happens because we use the same area to speak and to talk to ourselves. The book talks a lot about English grammar and it's not so good for non-native English speakers (like me). The book is good and there were some interesting insights, but some parts were just tedious for me. Here are my raw notes about the book: Meaning is something that you point words to. When you're learning a new language, you are pointing words to a meaning</li> A meaning can be a real world experience made by sounds, smells, movements and so on.</li> Torture means different things for different people. You may think of it as an iron maiden when a different person think about a different thing</li> We imagine sounds with the same region of the brain as we hear sounds</li> The same area of the brain activate for executing an action, thinking about an action, and understanding a word about an action</li> Think about how people will simulate the movement when you're writing a sentence. If the definition of the object or its shape is at the end of the sentence, it will take longer for the reader to simulate the scene.</li> Expertise affects how people understand language</li> TMS, powerful magnet that affects neurons. You can't even use your inner speech correctly</li> The language you speak makes you think differently. Egocentric versus geocentric to describe a place.</li> </ul> Review of Deep Work: Rules for Focused Success in a Distracted World Unknown — Wed, 31 May 2017 00:00:00 +0000 Book: Deep Work: Rules for Focused Success in a Distracted World</a> by Cal Newport. Rating: ⭐️⭐️⭐️⭐️⭐️. re-reading 2017 I will work on a new project and this book will be a perfect fit for the new work environment, so I decided to revisit it. I wrote my book (Desconstruindo a Web: As tecnologias por trás de uma requisição</a> using Deep work and it was an amazing experience. Embrace boredom is the most difficult practice from this book. I use my phone a lot but most of the time I'm listening to audiobooks or podcasts. Instant messengers are still part of my daily life, I have to schedule some time to use them. A good quote for that: "Don't take breaks from shallow work, take breaks from focus!" review 2016 This book is awesome! It summarizes what I think about concentration and the "new" concept of open offices that we have today. I have a big problem to concentrate when there is too much noise or when people could not stop talking to me. Unfortunately, this is part of the "culture" where and sometimes people came to just say "hi" and break my concentration entirely. I'm not a big fan of social networks, so I'm not using them in the last years. Sometimes I decide to get back to some of them just to realize that this book is right on everything about useless time spending. As an experiment I've been trying deep work on my weekday mornings and for my personal project on weekends. Most of the time I'm using 3-4 hours on the task and it really work the effort. No communication, no social networking, no random internet surfing and more work done. There is some really good information that bases deep working and helps you to apply it to your life. It will definitely change the way I work. Review of Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future Unknown — Thu, 18 May 2017 00:00:00 +0000 Book: Elon Musk: Tesla, SpaceX, and the Quest for a Fantastic Future</a> by Ashlee Vance. Rating: ⭐️⭐️⭐️. It's not a life-changing book but it's cool to understand Elon Musk path. Here are some few sentences I like and some comments on them: The best minds of our time are working to make users click on ads </blockquote> That's really sad. Elon has a great vision of the future and you can feel like him when reading the book (at least I can). I had to pause the audiobook for some minutes after that. If the rules are such that you can't make progress, then you have to fight the rules. </blockquote> It's really hard when you're doing something good but you have many bureaucrats and detractors trying to keep things as easy as possible. Break the rules is sometimes the best thing to do, you just have to be prepared to deal with the consequences. Elon was ready to do whatever he needs to make things work, no matter the consequences. He also explains why these rules exist and why it's difficult to change: If a regulator change a rule and something bad happens, he loses his career. If something good happens he got nothing in return. </blockquote> In this case, you have to take the responsibility to be able to break the rules. Elon is passionate about his vision. He is not just making business, he is trying to make the world a better place. Things like "take the man to mars" is not a business, but it's one of his main goals. I don't know if I would feel comfortable working for Musk, there are many bad stories of working for him. But this is the price of his empire. There are some stories about Elon firing an employee because he said it cannot be done. Musk took his position and delivered the work on time while doing his own job as well. As you may be thinking now, he's not a 9-5 guy. ;) That's it. If you want to understand what is it like to work for an almost unreachable dream, this book may be a good fit for you. Here are my raw notes about the book: The best minds of our time are working to make users click on ads</li> He found out the employee who told about the finances of Tesla by copying the text to a word document, printing it and comparing with other printed documents</li> If the rules are such that you can't make progress, than you have to fight the rules.</li> If a regulator changes the rule and something bad happens, he loses his career. But if something good happens he got nothing in return.</li> </ul> Stats for April, 2017 Unknown — Mon, 08 May 2017 00:00:00 +0000 This was not a good month. I spent most of the time sick, recovering from what may be a Labyrinthitis. I still have to confirm that, but I'm in slow motion for a while. But anyways, let's go to the collected data. Books</h3> Books for this month: </a> "Einstein no Brasil" (Einstein in Brazil) is a physical book I borrowed from a friend and The Art of The Lord of the Rings</a> I have in my shelf (as a good LotR fan). The power of broke</a> is an audiobook from the guy of the Shark Tank TV show and Spaceman</a> is a great book from Mike Massimino</a>, the astronaut. Articles</h3> I'm using the same export file from Pocket</a> and the same script to calculate my articles: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 824 596</code></pre> It means I have 824 articles Unread and 596 articles Read. Comparing with my results from the last month, I got almost 8% more unread and less than 5% more read articles. I have to work on that. :P Coding</h3> Here goes the charts from Wakatime</a> since the last post. </a> It was going well at the beginning but then I got sick and my productivity is dropped with it. I was playing with Python a little bit, so I had Python, Ruby and Go as the most used languages for this month: </a> Emacs is my main editor but Vim is still there. I configured my Bash to send reports to Wakatime as well</a>. </a> Speaking</h3> Unfortunately, there was no presentations for this month. My goal for this year is to beat Milhouse</a> best score (19 presentations last year). Here is my burn down chart for this (actually, a burn up [?]): </a> Podcasts</h3> As I said in my last stats post, I'm back to Podcast Addict</a>. This time I decided to buy the application, the developer deserves it. Here is the data: </a> I removed some data to become easy to see April stats. It was 2 days and 18 hours listening to Podcasts this month. As I'm using Podcast Addict again, I decided to keep a list of the Podcasts and their times as well. </a> Hours working</h3> Here is the data from my current time tracking, Toggl</a>: </a> The above chart is just for my freelance and full-time job. There is another chart for my personal projects: </a> My data from RescueTime</a> is not so good for this month: </a> But I was expecting something like that already =/ Physical activity</h3> As expected my average of steps a day dropped. Currently it's around 6k steps. </a> My max distance was 9.3km walking: </a> My weight is almost the same for the whole month. There is a visible outlier because I was testing a different application and inserted an invalid value. My fault. </a> Again, I slept more this month but with less deep sleeping, but just 1 minute less: </a> TV Shows</h3> According to tvshowtime</a> I watched 22 episodes this month. </a> It's probably a combination of Better call saul, Sense 8, and How I met your mother. As you can see, the first days of May already have a lot of episodes watches, and it's because of a How I met your mother marathon. I spent almost 1 day of my life watching TV Series this month. Locations</h3> This month I visited 13 more places (the last month were 325 places): </a> Words written and errors</h3> I'm using Grammarly</a> to improve my English and track the amount of words and errors when I'm writting. Unfortunately, they only send weekly emails, so I don't know if I will keep these metrics because it take some time to build it. Here is an example of the data sent via email: </a> Anyways, here is the data for this month: 37844 words written</li> 168 corrections made</li> 15160 unique words</li> </ul> Here are my common mistakes: 267 Possibly confused preposition</li> 100 Missing comma in compound sentence</li> 38 Confused preposition</li> 6 Comma splice</li> 4 Missing comma after introductory phrase</li> </ul> Expenses</h3> My expenses for this month are balanced again: </a> This chart represent only 15% of net income, the rest is being invested. This month was atypical because I received the money related to my freelance work on January and March. I also received the yearly bonus from my full time job. This month increased my total savings by 9%! Pretty good! :) Conclusion</h3> It was not so nice to be sick, as expected. My productivity dropped a little bit and I have to go to the doctor this month and look for it. Hope to be in a good health next month. :) Review of The Power of Broke: How Empty Pockets, a Tight Budget, and a Hunger for Success Can Become Your Greatest Competitive Advantage Unknown — Sat, 29 Apr 2017 00:00:00 +0000 Book: The Power of Broke: How Empty Pockets, a Tight Budget, and a Hunger for Success Can Become Your Greatest Competitive Advantage</a> by Daymond John. Rating: ⭐️⭐️⭐️. An ordinary book. 3 stars are good enough. The whole book discusses how to do business when you have no money. Daymond is the man behind Fubu and a TV show called Shark Tank. His story is really interesting to follow because he raised his entire business out of nothing, following the power of broke principle. Throughout the book, he shows similar stories to show the power of broke in action. It's a good principle but nothing extraordinary. If you need motivation or are using excuses because "you don't have enough money" this book may be good for you. Here are my notes for this book: When you got nothing to lose, you got everything to gain</li> Innovation goes bottom up, not top down</li> Use your disruptive technology</li> Fail is important. Try and fail as soon as possible. Learn from it and keep going.</li> At social networks, you have to be consistent.</li> If you don't have the opportunity, build one. (Skateboard competition entrance)</li> When you're broke, you have to make smart decisions, or it will cost your whole business</li> Position yourself for winning. Try to be in the right place, talking to the right people.</li> Think like your client. Michael Jackson used a crappy radio to hear his songs because this is how people listen to it</li> You don't have to know everything to start a business. Just know how to get the missing parts ant and move along.</li> Rules 1. Use the best resources available to you</li> Rule 2. Keep it real. Put authenticity in everything you do.</li> Rule 3. Optimize. Time is precious</li> Rule 4. Solve people's problems and be rewarded.</li> Rule 5. Put your passion on everything you do.</li> Rule 6. Appreciate everyone you meet on your path</li> Rule 7. Think beyond. Use data to support you</li> </ul> Review de Einstein no Brasil Unknown — Thu, 13 Apr 2017 00:00:00 +0000 Book: Einstein no Brasil</a> by Aguinaldo Prandini Ricieri. Rating: ⭐️⭐️⭐️. Um livro comum, com apenas um quote que valeu muito a pena. No geral consegui extrair algumas poucas boas informações sobre o Einstein daqui. Muita coisa do que tem nesse livro é parte do contexto do Brasil em 1925. Apesar da visita do Einstein ter sido noticiada em vários jornais e ele ter recebido homenagens de vários grupos, não teve nada muito revelador. A parte mais interessante do livro é uma entrevista onde ele fala uma coisa interessante. Ao perguntarem para ele sobre o que ele achava do futebol, teve a seguinte declaração (nas palavras do jornalista): Qualificava-o de ótimo sport, muito bom para a saúde do corpo. Se porém, o football passa a ser preocupação maior de um povo, julga que é para se lamentar. Para exercício aprova-o, para ocupação exagerada ou para motivo de paixão exaltada, acha estúpido quem o toma em consideração. </blockquote> Não precisa ser um gênio para chegar a essa conclusão, mas é interessante ter pessoas importante dizendo esse tipo de coisa. Review of Spaceman: An Astronaut's Unlikely Journey to Unlock the Secrets of the Universe Unknown — Thu, 13 Apr 2017 00:00:00 +0000 Book: Spaceman: An Astronaut's Unlikely Journey to Unlock the Secrets of the Universe</a> by Mike Massimino. Rating: ⭐️⭐️⭐️⭐️. Great book, 4.5 stars. Mike does a great job describing how is the life of an astronaut. Listen (yes, I used an Audible audiobook) to his story was like living it with him. I could feel how was to be waiting for the NASA phone call after so many years trying to be an astronaut. Being an astronaut is being part of a family. This is one of the main messages in the book and you can feel it. Today, working for companies, it's hard to get something like this. A great sentence of the book: You just have one life, you must do something that matter </blockquote> It makes a lot of sense for someone who works for NASA and it should make a lot of sense for all of us too. I remember telling my mom I would like to be an astronaut when I was a child, but it was just a dream at the time. Mike decided to go for it and became the man responsible for fixing the Hubble telescope. That's pretty amazing. It was not easy (far from it) but he did it. There are many variables to consider, but it was really great to read it. Review of Smarter Faster Better: The Secrets of Being Productive in Life and Business Unknown — Mon, 10 Apr 2017 00:00:00 +0000 Book: Smarter Faster Better: The Secrets of Being Productive in Life and Business</a> by Charles Duhigg. Rating: ⭐️⭐️⭐️⭐️. It is a good book. I almost gave 3 stars, but it is still a Mastery effect. It deserves four. Each chapter in the book is devoted to a specific area: Motivation, Teams, Focus, Goal setting, Managing others, Decision making, Innovation, and Absorbing data. My notes on each topic: Motivation</h2> Motivation is feeling in control.</li> There is an example of the marines training. The training is not exactly about combat, but about doing what you think you couldn't do.</li> </ul> Teams</h2> He explains the results of project Aristotle from Google. You don't need stars on your team, you must have a team that cares for each other, where all opinions matter. Read more about https://en.wikipedia.org/wiki/Psychological_safety</a></li> </ul> Focus</h2> Focused teams solve emergencies better.</li> Develop mental models</li> Anticipate what may happen. What will your wife say at some situation? What will happen if a specific piece fail? Build mental models for many situations as possible</li> </ul> Goal setting</h2> Be careful with to-do lists, you have to use them in the right way. You may waste a lot of time just to "reach your goal" and have a clean list. Things like reading emails is not a good goal. Plan for smart goals.</li> </ul> Managing others</h2> This chapter is all about Lean and the Toyota way. Learn to listen to your employees and give them enough space to improve the whole process.</li> </ul> Decision making</h2> No one can prevent the future, but with enough data, we can forecast some events and even improve the chances of success.</li> </ul> Innovation</h2> Innovation is usually a combination of previously known ideas mixed up in a new way.</li> The most innovative ideas came from people who deal with multiple groups or departments. People who can explain a concept to other departments easily.</li> Toyota gives space for every employee to innovate and improve the process. Disney gives the chance to their employees to put their emotions into the movies.</li> </ul> Absorbing data</h2> Collect data and try some hypothesis on it. Every choice is an experiment.</li> When we learn something, we should force ourselves to interact with the data. Try to explain a new concept to a friend for example.</li> </ul> Review of The Art of The Lord of the Rings by J.R.R. Tolkien Unknown — Fri, 07 Apr 2017 00:00:00 +0000 Book: The Art of The Lord of the Rings by J.R.R. Tolkien</a> by Wayne G. Hammond. Rating: ⭐️⭐️⭐️⭐️. This is one of those books for Tolkien fans. I do not recommend it if you did not read other books by Tolkien. It is nice to read if you already read The Hobbit and The Lord of the Rings</a>. This book shows a lot of details that Tolkien used as a guideline to write the book. He did not consider himself an artist but this book shows awesome drawings made by him. As it's about all drawings made during the writing of The Lord of the Rings, there are some drafts of drawings and other stuff that is not interesting. I found amazing how he managed to calculate how many miles Frodo and Sam had to walk to Mount Doom and synchronize that with the last battle in the gates of Mordor. Stats for March, 2017 Unknown — Tue, 04 Apr 2017 00:00:00 +0000 Back to work this month. :) After one month vacation, I got back to my routine and got some good results this month. Books</h3> Added three more books to the list: </a> I have to note here that Mastery</a> is one of the best books I ever read</a>. Both Mindfulness in plain English</a> and The Urban Monk</a> are about meditation and how to live a minimalist life. Articles</h3> I'm still trying to find a way to track the articles I read. In the past months I've being adding all of them to Pocket and reading there. Unfortunately I could not find anything to build information from my pocket reading data (suggestions welcome). For now I'm just exporting my content in HTML format</a> and using a simple Javascript to count it: var uls=document.body.getElementsByTagName("ul"); for(var i=0; i<uls.length; i++) { console.log(uls[i].children.length) } 760 570</code></pre> It means I have 760 articles Unread and 570 articles Read. Let's see how it will be next month. ;) Coding</h3> I've changed the charts from Wakatime</a> since the last post. Let's check the new ones: </a> There is no colors or day numbers anymore but it looks better to understand how many hours I've been working through the month. It's still less than what I was expecting, but that's the main idea, time to improve! Ruby and Go are the most used languages for this month: </a> Markdown is just my posts here. LOL I'm shifting from Vim to Emacs, but I still use Vim a lot: </a> Speaking</h3> Presentations for this month: Tech-talk at Locaweb</a>. It was a Tech-talk about FOSDEM</a>. Every time I go to a conference I schedule a talk to explore the content I saw there. I consider that a good practice with my coworkers.</li> Gaveteiro</a> it was the same presentation that inspired my book</a> but with a small audience. It took 1h 52min and was pretty cool (at least for me). :)</li> </ul> Podcasts</h3> Back to Podcasts again! This time I decided to try a different Podcast player after many years using Podcast Addict</a>. I bought Pocketcasts</a> and I used it for the whole month. </a> Don't worry about the "Since 29th of January" because I did not used any podcast player in February. ;) I really don't know what these numbers mean. But 1 day of podcast listening make sense for me. I usually listen podcasts 3x faster, this is what causes the confusion. :P I will probably get back to Podcast Addict in April, because it's superior in many features. Maybe I will write about it soon. Hours working</h3> My time tracking with Toggl</a> is more mature now. </a> Besides the 206h30min I have 6h30min working on my personal projects. RescueTime</a> says I reached my goal for the month: </a> That's great. :) Physical activity</h3> Back to the old rhythm, around 10k steps: </a> My max distance was 11.5km walking: </a> My weight is not there yet, but I'm still tracking: </a> I slept more this month but with less deep sleeping: </a> TV Shows</h3> According to tvshowtime</a> I watched 29 episodes this month. </a> It's probably a combination of Vikings</a>, Luke Cage</a> and Iron Fist</a>. Locations</h3> This month was not so exciting like the last one, but I worked on my Google Timeline</a> data to make it more accurate. Some cities were removed but I have identified more places I visited: </a> Expenses</h3> Phew... finally my expenses are getting back to normal, no more travel taking 50%+ of it. But it's still taking 25%+. :P </a> This chart of expenses represent 46% of net income, the rest is being invested. Conclusion</h3> It's good to be back and see my productivity data growing. I still want to improve my expenses because it's not as I expect it to be. Maybe next month. :) Stats for February, 2017 Unknown — Mon, 03 Apr 2017 00:00:00 +0000 February was an atypical month because I was on vacation. :) Much of my stats will reflect my travel around Europe. But no coding was done during this trip. Books</h3> Continuing my goal to read 30 books this year, I read two books this month: </a> I had plans to visit Amsterdam and Oxford during my travel. Because of that I decided to read the story of Kullervo</a>, which mention a lot about J.R.R Tolkien past (it was one of his first stories), and The Diary of a Young Girl</a>, because I had plans to visit Anne Frank's house in Amsterdam. Coding</h3> As I said in the beginning, there was no coding this month. I left São Paulo in Feb 2 and got back in Feb 28. So, my Wakatime</a> charts are empty for this month. Speaking</h3> The whole reason of this month's trip was to speak at FOSDEM</a>. I planned the talk to be fast, but as it was my first English talk in a conference and I was pretty nervous, I spoke faster than I was expecting. :P This was the only talk for this month, if you want to check it out go to the talk page in the FOSDEM website</a>. Podcasts</h3> I've downloaded some podcasts and audiobooks to listen during this trip but did not listened to any of them. I was in a different mood during the trip. :) Hours working</h3> Guess what!? No working hours this month as well :P Physical activity</h3> Hm, that was huge! haha This is the chart for steps. It may not be clear, but the peak is 34k+ steps in one day! </a> As you may expect by the amount of steps, the distance is high as well. My max was 31.5km walking in Feb 6th. </a> By using miband, I can also track the amount of sleep for this month: </a> I was waking up pretty early during the trip. :) Locations</h3> I'm using Google Timeline</a> to track the places I'm visiting. This month I received the first email with a summary of the new places I visited during the month. If you have an Android phone and you don't like this tracking, just disable it in Google location tracking. This month was interesting to share because of my vacation travel. I visited some new countries: </a> Some cities in those countries: </a> And many places in those cities: </a> In general, I visited many places since it started tracking my location: </a> I will not always share all those images, but at least big picture will be here as a benchmark :) Expenses</h3> This is something I'm planning to do for a long time now but never got the chance. I always keep track of my expenses and now I decided to publish here as well. It will not have values (because it don't need to), but here is the chart for my expenses by category: </a> Most part of my expenses was covering the travel expenses for my Eurotrip this month. But this chart of expenses represent only 22% of net income for this month because of the month salary and "bonuses" we got before leaving for vacation. Conclusion</h3> February was a different month, I cannot compare it with the other ones, but it was pretty great. There are some posts about the events of this month in case you want to read it: Oxford for Tolkien fans</a></li> FOSDEM Survival Guide</a></li> My presentation at FOSDEM 2017</a></li> </ul> Now, it's time to get back to work. Stats for January, 2017 Unknown — Sun, 02 Apr 2017 00:00:00 +0000 This is the first post of a series that will show all the data I've been collecting during the month. One of my goals this year is to track everything possible. These posts will help me to analyze all the data and may extract something for me. This is not a new idea, I'm inspired by posts like this</a> from Matthew of truevalhalla.com</a>. Books</h3> My goal is to read 30 books this year, so I must have an average of 2.5 books per month. I read two this month: </a> Outliers</a> is a great book, I really recommend it. It talks about the 10.000 hours role to master something. The Memory Illusion</a> is about how your mind trick you creating false memories. Coding</h3> To track my time coding I'm using Wakatime</a> (this link is a referral, use it in case you want to try it out). By using it I can see the amount of hours I spent programming: </a> Don't worry about the colors in this chart, each project has it's own color but it's not relevant for this case. My best best day was Jan 19th, almost 12h coding. Now we can check the languages I'm using: </a> I have no idea what this "Other" means. The purple one is Elixir</a>. I'm playing with it and it's great. Here is the controversial fact. My text editors: </a> Forget about Chrome, I was testing a feature from Wakatime. But yes, I'm using both Vim and Emacs. :P Speaking</h3> I spoke three times this month, here is the list and descriptions: Campus Code</a>, it was opening the Quero ser dev program. I was talking about the chooses we made as developers during our careers.</li> Impacta</a>, speaking about what what happens behind a web request. This is the presentation that inspired my book</a>.</li> Campus Code</a>, after 6+ rehearsals I was trying my talk "Open source behind a web request" for an actual audience. It was my first talk in English.</li> </ul> Podcasts</h3> I'm a big fan of audio programs. I have many audiobooks and podcasts in my collection and I listen to them whenever possible. This is my stats for this month, thanks to Podcast Addict</a>: </a> The big numbers is my total time, but look at the "January 2017" time. Hours working</h3> I'm testing Toggl</a> to track my working hours. This is the first month and here are the results: </a> I'm also using RescueTime</a> to track my apps on my cellphone and personal computer. It still needs some tuning but here are my goal of 3 productive hours per day: </a> I will work on that. Physical activity</h3> I try to keep a regular physical activity. After buying a simple and cheap Mi band</a> I can track it better. It's integrated with Google Fit</a>, so I can extract all those nice charts. This is the amount of steps this month: </a> Distance by day: </a> And I'm also tracking my weight, which is improving! :) </a> By using miband, I can also track the amount of sleep for this month: </a> Unfortunately this app does not know how to deal with sleep time when you sleep after midnight. This is the main reason why it says I'm going to sleep at 07:20 and I'm waking up 07:18 (???). I will workaround this bug by avoiding to sleep after midnight, as I'm waking up around 6. :P TV Shows</h3> I don't watch so much TV but it's a hobby of mine (and my wife) to watch TV Shows on Netflix. We also watch Game of thrones on HBO when available. I'm using tvshowtime</a> to track it and here is my stats for this month: </a> Expenses</h3> This is something I'm planning to do for a long time now but never got the chance. I always keep track of my expenses and now I decided to publish here as well. It will not have values (because it don't need to), but here is the chart for my expenses by category: </a> Yeah, I know, all categories in pt-BR. This chart comes from a Brazilian app called GuiaBolso</a> and it's the best I have for the moment. As you may expect, it takes a lot of time to collect all these data, so I will keep it as is for a while. Most part of my expenses was covering the travel expenses for my Eurotrip next of February. Conclusion</h3> This is the first post, so there are many details missing. The idea is to start "simple" and keep improving in the next months. As it's not so easy to write posts like these, I'm trying to create some "templates" for it. It was a pretty good experience to see all that data together. :) Let's see how it goes in the next months. Review of Mindfulness in Plain English Unknown — Wed, 29 Mar 2017 00:00:00 +0000 Book: Mindfulness in Plain English</a> by Henepola Gunaratana. Rating: ⭐️⭐️⭐️. I was expecting some more but after reading the description again it seems to deliver exactly what it says. The whole book is about meditation and I would say 50% of it is about focusing on your breathe. The chapter about loving kindness is also interesting. There are some quotes of Buddha that are really great. Here are my raw notes about the book: Meditation is not just for holy man. They are holy because they meditate, not the contrary.</li> The real peace comes only when you stop chasing it</li> Investigate yourself. Take nothing as granted. Question everything. Don't believe in anything because it sound wise or some holy man said, see for yourself.</li> Face reality, don't try to mask your problems.</li> Suffering is different than pain. Pain is inevitable, you will feel it someday. But suffering you may avoid, be prepared for it.</li> Mindfulness is about the present. If you remember your school teacher, that's memory. When you become aware of remembering, that's mindfulness. When you say: "oh, I'm remembering...", That's thinking.</li> Concentration is just like a lens, it amplifies your thoughts to go deeper. Use it as a tool.</li> Madama pata who anticipated froid by one thousand years</li> You understand others by understand yourself. Meditation help you with that</li> When you learn compassion for yourself, compassion for others is automatic</li> Buddhism advocates that faith in the sense of believing in something because it's written in a book, attributed to a prophet that talks to you by some authority figure. Faith is something you have seen it happen within yourself.</li> Meditation is not just for holy man. They are holy man because they meditate, not the contrary.</li> If you start a meditation practice to understand you, nature and life, you will succeed in your practice.</li> The real peace comes only when you stop chasing it</li> The process of meditation is learning to live</li> Investigate yourself. Take nothing as granted. Question everything. Don't believe in anything because it sound wise or some holy man said, see for yourself.</li> View all problems as challenges</li> When looking to yourself from "outside" you may find some things you don't like.

Rating: ⭐️⭐️⭐️. The author was a Monk for 4 years, is a Doctor of Oriental Medicine and studied Kung Fu and Tai Chi for decades, this is what you will get from the book. There are some chapters with a lot of meditation techniques and some tips about sustainability. The idea is to help you to live like a monk in the urban landscape. There are not so much scientific studies shown as references here, it's more like a religion, which is not so unexpected. Besides that, I got some good info from the book. Each book resonates with you in a different way. Here are some notes worth mentioning: Tai Chi is not a class, is a way of life</li> The exterior world reflects your inner feelings, be happy and the world will be better for you.</li> Companies pay for work and results, not dead time. Don't just sell your time, do something you love.</li> TV and social media are shit. (nothing new here, right?)</li> Be grateful for food, remember that a life was taken for it. Why you deserve to live instead of the dead creature that became the food? We are not hunters anymore. Don't think about it as meat only, it applies to vegetables as well, he's talking about energy and stuff.</li> In our culture we feel aversion for pain. We don't like feeling unconformable. Our whole culture makes us run away from pain.</li> Get uncomfortable. Try something that gets you out of your shell.</li> Nobody cares if you suck at doing something, all beginners do. Just do it for the joy of doing without the worry of judgment.</li> Be aware of the advertising industry. You don't need most of the things they are trying to sell you. Think about it. An urban monk does not invest his money in shit he doesn't need.</li> </ul> And the last one, to keep your life on track: If time, money and place were not in consideration what would I love to do with my time? Question yourself: why? What can I do to go there? What stands in my way? Is this a real or perceived limitation? How can I transform these obstacles? How can I change my current lifestyle to accommodate this? Review of Mastery Unknown — Sat, 18 Mar 2017 00:00:00 +0000 Book: Mastery</a> by Robert Greene. Rating: ⭐️⭐️⭐️⭐️⭐️. One of the best books I ever read. This book goes through the life of various masters of our history. Some of them I did not know and decided to look after their life, which was a great experience as well. If you want to be a master of something, be prepared to use a huge amount of time dealing with it and practicing. Masters don't become what they are by just working 9-5 and watching television in their spare time. They are passionate about what they do and most of the time they don't care about how much money it will generate for them. In the last moments of his life, Einstein was still writing equations about his hypothesis. Champollion tried to decipher the Rosetta stone for 20 years of his life, trying multiple time and learning from it. Daniel Everett had to immerse in the life of Pirahã people for 12 years in order to understand their culture and language, which made him abandon his faith in Christianity (because of the relation between culture and religion). These are just some of the stories from the book. This book resonated with the Einstein: His Life and Universe</a> and with the stories I heard about Benedito de Espinoza. Masters like them had strong beliefs on what they were doing/researching and dedicated their life to it. Some of the stories presented in the book made me think differently about how to approach problems and how to plan my life to reach my goals. Here are my raw notes about the book: In the past there was no information about many topics and now we have information that ancient masters could not even dream about</li> Learn who you really are is the first step</li> For ppl/Leonardo da Vinci, the end product is not what matters, but the process of building it.</li> ppl/Leonardo da Vinci: a well employed life brings a blessed death</li> You have to express your uniqueness through your work, you have a destiny to fulfill.</li> Social pressure to conform may let you down because of your uniqueness. Your parent may be a force against as well, they may want you to go to a more lucrative career path. Don't let these forces to be strong enough or you may loose contact with your uniqueness.</li> Make your work your vocation. We spend much of our wake life there.</li> To find what you really like, you may look to your past. What do you really find interesting? What makes you wnat to know more every day?</li> ppl/Charles Darwin noticed that animals change between islands according to the habitat</li> ppl/Wolfgang Amadeus Mozart gave up his family because his dad was jealous of his talent. He had to do that in order to keep growing.</li> It's better to have a few hours of concentration than many hours of multi-tasking</li> To master is to become part of an instrument</li> 10000 hours of practice to master something</li> Apprenticeship: watch, practice, master</li> ppl/Albert Einstein found a job that was simple to do and has interesting knowledge for him. This job was mastered and could be done in 2 or 3 hours, so he will have the chance to work on his ideas.</li> Your thoughts tend to evolve to what you value the most. If it's money, you will find a job that has the better paycheck and work hard to be worthy.</li> When learning a new thing, feel inferior like a child to absorb everything from a superior (knowledgeable) master.</li> If you're feeling uncomfortable about something, do it often until you feel comfortable.</li> Be your own critic, push yourself to the limit and look your acts through the eyes of others.</li> It's a good thing to fail, you just have to learn from it and improve your ideas to try again. ppl/Henry Ford failed multiple times but still got what he wanted with hard work and persistence</li> You want to learn as much skills as possible but avoiding the ones that not contribute to the career path you want. You avoid the following of just one strict career path. You know what kind of skill suits you and what to avoid at all cost.</li> If you follow just one strict career path, you may find a dead end or lay in boredom when you're older.</li> Find a mentor and work with him. It you make you discover how to think about solving problems and the process to connect ideas to the solution. When you're mature enough, follow your own path</li> Poor is the apprentice who does not suppress their master - ppl/Leonardo da Vinci</li> Look to the situation from the others perspective to be able to understand what they want and take advantage of it</li> The definition of fool. Thinks about the short term, ego and how they will look to the others. They don't care about the truth but their career instead. We may have our own moments of foolishness, its natural. The best way to deal with fools is to ignore them or use their actions in your favor to accomplish long term goals and important things.</li> Choose the right task. The task that you will emotionally commit. Tasks with shallow connections with you will just drop your commitment rate and make you sad to work on it. It would be a worthless creativity expend. #needsreview</li> Think not just about what is happening, but what is missing. Why something that should have happened didn't.</li> Don't hurry up learn the basics (chapter 14 30 min). With the basic knowledge mastered you may use your own style to create new things, using everything you leaned in a combination to develop you brand new idea.</li> When you look back through tne years, you have to feel that it was enjoyable to work on that. It should not be a laborious work. Enjoy it, time is on your side.</li> Things do not come from nowhere, you can use something you already know and transform (or reverse it) to something completely new. People like (or get used to it with time) new things and you will get your own audience.</li> Sometimes we focus too much on the details that we forget the reason why we're doing it, the true goal. It's always important to keep this goal in mind. In the case of the prosthesis, the important is to make a good hand, not to make the best engineering possible for it.</li> We should exercise our brain in our spare time. Games, Music, etc. Currently, we don't do that much, the devices do that for us.</li> Masters use intuition for many things. The amount of time working brought a lot of knowledge that is used automatically</li> Masters chose to follow their own path at a given moment in their lives. It may seem unconventional for othersbut make them feel happy.</li> Mastery is just like swimming, it's difficult to achieve when you're creating your own resistance or swimming against the current. Know yours strengths and move with them.</li> Practice makes connections in our brains. It's insane to try to learn something complex without many hours of practice. Practice is the way to Mastery.</li> The missionary that went to learn a new language from a tribe to convert them to Christianity reached the conclusion that his work as a missionary didn't make sense. Convert that tribe to Christianity would destroy their culture that works perfectly for their needs, in the environment they are living in. He lost his faith in Christianity because he got to the conclusion that it's not possible to have one faith that works for everyone.</li> When he went to the first with the tribe, he truly understood their culture. They have a language for hunting and understand every inch of the forest. By knowing the dangers and diseases of place, they don't that that much empathy by the people because being attached generates suffering. When they see a person dying, they prefer to end their suffering as soon as possible.</li> The false self. Other people's ideas for a society, your own ego and some other things. It tries to make you think Mastery is just for the genius, the amount of work doesn't work the return, or that masters were just people that were in the right place in the right time.</li> When pursuing Mastery you are following your inclinations and contributing to society. To just use things other people create is selfishly.</li> Motivation is one of the things that keeps you on the path. Feel bored only keeps you down</li> </ul> Oxford for Tolkien fans Unknown — Fri, 10 Mar 2017 00:00:00 +0000 TL;DR: When traveling to Europe, I decided to take 2 or 3 days to visit Oxford. I will describe how was the experience of a J.R.R. Tolkien fan there. I'm a big fan of J.R.R Tolkien. Have read most of his books, the ones released when he was still alive and other edited by Christopher Tolkien. After attending FOSDEM</a> I decided to travel around some countries in Europe and UK. The most expensive part, the airplane tickets (Brazil -> Europe), were already paid, so... why not? :) The last step of this journey would be London. Then I realized: "Why not to visit Oxford?". It's a historical city and Tolkien himself wrote most part of his books there. I used the Oxfordbus company as transport from Heathrow Airport to Oxford center and choose a cozy house to stay via Airbnb for 3 days and 2 nights. Everything in Oxford closes really early. I got there around 4pm and there was nothing to do anymore. I tried to visit the Bodleian Library, but it was closing. All colleges were closed. The only thing to do is to look for a place to eat. The first stop for real was Eagle and Child. This was the pub where the Inklings met once a week in the morning. For those who don't know the Inklings, it was a small group which J.R.R. Tolkien and C.S. Lewis were members. They used to talk about their books in these meetings. The Lord of the Rings had their first drafts showed in this pub, probably. It's a good place to eat, I liked it. I was lucky to be in Oxford in a Wednesday, they have extended tours around the Bodleian Library and Radcliff camera on Wednesdays and Saturdays. There were some good stories about it, but unfortunately it's almost impossible for a tourist to see any of the Tolkien's manuscripts or original materials. In order to get access to it you need to have the Readers card. In order to obtain it, you have to pay and justify why you need to have access to the them. So... No manuscripts for me. The guide of the Bodleian Library did not know anything about Tolkien, just the history behind the Radcliff camera and the Bodleian Library. The extended tour is expensive (£24, I think) but worth the price. I went to the Weston Library, where they have a treasury room with a free exposition. There I found a original drawing from Tolkien. But the other manuscripts were already removed because they are planning to close this exposition (as they said...). Tolkien was a teacher at Merton College, you have to pay £4 to enter there if you want to. After asking about Tolkien places to visit, I found that none of the places I would like to visit in there were open to the public. From the inside I could see (through the gate...) the rounded table that may have inspired the meeting that created the fellowship of the ring. I got this picture thanks to my 55-250mm lens, but it is not so close from the gate. To enter there you have to be a Merton associate (or something like that). But is still a good place to visit. I decided to visit Magdalen College (£5) to walk in the "Addison's Walk" where the Inklings talked about religion and where C.S Lewis was converted to Christianity. Unfortunately, the wind was causing some threes to fall down and they had to close the place for security reasons. There was a exposition in the old library of the Magdalen College and it was cool to see the old books. From the times they still had chains in the shelves. :) There is a good place to find Tolkien books, in case you're interested. Go to Blackwell Bookshop</a> and look for the shelf dedicated to J.R.R Tolkien. In the last day, I decided to go to the cemetery where Tolkien was buried (Wolvercote cemetery). It's not so far, but almost 1 hour walking. There are some buses that take you there easily, just go to the bus station to get information. I like to walk around the cities I visit, so we went there walking. It's a simple tombstone, nothing spectacular, but I'm glad to get there. Then we came back walking and passed in front of the house he lived with his family for some time. Other things around Oxford</h3> You're already in Oxford, so I recommend you to visit the Blenheim Palace. It's expensive £23 (go by bus and buy the tickets on the bus because it's cheaper than buying there) but worth the price. It's not the Highclere Castle from Downton Abbey, but some rooms were made me think about it. :) Walk around the Carfax Tower and the Oxford castle. I liked both structures. The interesting part about the Carfax Tower is that it is there since 900 a.c. The architecture for all colleges is really impressive, just walk around them if you like it. I'm a big fan of these kinds of architectures, so I enjoyed walking around them and taking pictures (yes, I like photography too!). Conclusion about my Tolkien Tour</h3> There are some other pictures related to Tolkien in this Google photos album</a>. I was expecting to see more materials from Tolkien. There were no expositions about him, the only thing I saw was a drawing. I know that all (or at least, many) of his manuscripts are available at the Bodleian Library, but they're not accessible. The city do not use the fact that Tolkien lived there as touristic attraction. The only place referencing Tolkien was the Eagle and Child. But Oxford is a good city to visit. There is a lot of history there. I just recommend you, J.R.R. Tolkien fan, to align your expectations with what is there. FOSDEM survival guide Unknown — Mon, 06 Mar 2017 00:00:00 +0000 TL;DR: It was my first time at FOSDEM</a> and it took some time to feel comfortable, this post may help newcomers. As I mentioned in my previous post, I spoke at FOSDEM</a> this year. It was my first time there (in the whole Europe, btw!) and it took some time to get used to the way the event goes. This post will show some tips that may help FOSDEM newcomers and maybe some veterans as well. What is FOSDEM?</h3> FOSDEM is the Free and Open Source Developers - European Meeting. Long story short, it's a big self organized event that happens in Brussels every year since 2013. The conference has many Devrooms organized by volunteers with a predefined schedule guided by topic. Aside of that are the main tracks, that are some unique presentations happening in some big rooms. The whole event survives from donations and some sponsors, but it's not organized by a company (like OSCON, for example). There are many volunteers that work hard to make it happen. How it works</h3> The conference happens at the Université libre de Bruxelles, using some buildings of the university. All the tracks are spread across these buildings. Depending on where you are, you have to reserve some time to reach the other building. It is not so far, but may take 10 or 15 minutes depending on your location. Think about the time it will take on the transition in case you want to watch as many presentations as possible. Also, plan ahead your time to be at the room because it may be full when you get there... FULL rooms</h3> FOSDEM is chaotic. It's is a good and a bad thing at the same time. Conferences like these, organized by the community for the community, are the kinds of events I really like. They tend to be chaotic, but it means people are free to do whatever they want. They can walk through the university and watch whatever they want. FOSDEM publishes a big schedule with information about all the presentations happening across all rooms and you may create your on schedule. I did it before going but forgot to consider the time between buildings and the "FULL" rooms. There are some limits that need to be respected, one of them is the number of people inside the room. When the room is fulfilled with people they add a "FULL" sign at the door and nobody is authorized to enter. It make sense, but is really annoying for newcomers. When planning your schedule, plan to get to the room at least 15 minutes before it starts. TIP: instead of jump between many rooms, it's a good idea to choose one or two and stay there for 2 or more presentations. It will guarantee a spot for you in the room. My schedule did not consider the time walking between buildings and the full rooms, so... could not enter in 4+ rooms I wanted to be in. Lunch</h3> There are some food trucks there. They do not give you a receipt (in case your company is refunding your travel, you may need it), so be prepared for that. It tend to be crowded at peak hours (noon, maybe?), try to get something to eat before or after. But be warned that it is almost always crowded. :) The conference don't have any breaks, if you want to eat something, you will have to decide to not watch a presentation and use the time for it. Parties</h3> They have a pre-conference party at Delirium. The bar is closed for conference members only (they ask some tech questions to get you in :P). It is not a huge place to have everyone in, so it will be really crowded and hot there. Almost the same amount of people will be chatting and drinking outside of the bar as well. After the first day of conference, there is a second party, usually in a hacker space in Brussels. Presentations</h3> Always read the presentation description. Some of them has "click bait" (attend bait in this case?) title, sometimes not intended. I attended to one of them about a language development. I was expecting something about the day-to-day of the language development and what features are planned for the future. Unfortunately, it was not what I (and many people in the room) were expecting. It was about the metrics and dashboards of the language contributors and features. In this case, it was not probably not intentional, but almost 50% of the room left before the presentation ended. Conclusion</h3> FOSDEM is a great event, I really enjoyed it! I would like to have received these tips before, so I would have planned my day better. Hope it helps the 2018 FOSDEM attendants. o/ My presentation at FOSDEM 2017 Unknown — Sat, 04 Mar 2017 00:00:00 +0000 This year my proposal to speak at FOSDEM</a> was accepted and I spoke at the Desktop devroom! :) It was my first talk in English, so I decided to do as many rehearsals as I could. I was 8 in total, but as expected, it was still a little bit faster than expected. :P I had 30 minutes to present and I did it in 26. I usually speak fast and this presentation was made to be fast because I had a lot of content to show in 30 minutes. So, it was FAST (even more than what I was expecting). LOL I'm OK with the final result. It's far from being my best presentation but it's the first one in a different language, so it's acceptable. They already published the video for my presentation, and it is available here</a> as desktops_open_source_behind_web_request. In case you want more information about the presentation, including the slides, you may want to check its page on FOSDEM Schedule</a>. FOSDEM was great, can't wait for the next! :) The Hague, Netherlands Unknown — Wed, 01 Mar 2017 00:00:00 +0000 After speaking at FOSDEM</a>, I did a bigger trip through a few countries, and one of them was the Netherlands. While going from Rotterdam to Amsterday, I decided to spend a few hours (almost a day) in The Hague. Transport</h2> I took a train there from Rotterdam and after that I got a bus. I don't really remember how those work, but it was quite simple for me to navigate it without any experience. Got to the place I wanted without major problems. :) Places</h2> Spinoza Museum: The main reason why I wanted to go to The Hague was the Espinoza Museum. It's probably one of my best experiences in museuns ever. The museum is located at the house where Spinoza lived most of his life, and it's not a popular place by any means. The place is mostly ran by volunteers, which made the experience even better. I got there with 2 more [random] people and we spend almost 3 hours talking about the museum and Spinoza's life. The old guy there was very excited to show us the place, explain the details, and tell us more about Spinoza himself.</li> </ul> Oxford Unknown — Tue, 28 Feb 2017 00:00:00 +0000 After speaking at FOSDEM</a>, I did a bigger trip through a few countries, and one of them was England. I'm a big fan of Tolkien, so I decided to explore Oxford too. I wrote more about it on the page Oxford for Tolkien fans</a>. Stay</h2> We got an airbnb not far from the main street where the universities were. I think 15 minutes walking were enough to get there. Nothing to complain about the airbnb, the host was very polite and helpful. I don't really think it's worth mentioning them here as it's been 5 years since I've been there and the listing may be very volatile, but if you really want it, please ping me and I can try to find it. Transport</h2> I got there by train and the rest was just walking around. Didn't use any kind of transportation inside the city. Places</h2> Magdalen College: Great university to visit. They have the “Addison’s Walk” where the Inklings talked about religion and where C.S Lewis was converted to Christianity.</li> Blackwell bookshop: A nice bookshop that has a section dedicated to Tolkien.</li> Bodleian Library and Radcliff camera: On Wednesdays they have (at least they had, in 2017) a bigger tour through the library and underground, so it's the best day to visit. The library is quite old and great to visit.</li> </ul> Food</h2> Eagle and Child: The place where the Inklings (J.R.R. Tolkien, C.S. Lewis, et al) met for their meetings. It's quite a nice pub.</li> The lamb and (???) [I really don't remember 😅]: is the other pub that the Inklings used for the meetings. Not bad at all and quite close to the Eagle and Child.</li> </ul> Amsterdam Unknown — Mon, 20 Feb 2017 00:00:00 +0000 In 2017 I had the chance to speak at FOSDEM</a> in Brussels</a>, and I used this opportunity to do a bigger travel through a few countries in Europe. After visiting a few cities in Belgium, I went up to the Netherlands and visited a few cities. Amsterdam was one of them. Stay</h2> This time I asked a few friends if I could borrow a room at their house and they accepted to host me and my wife for a few days. Right after coming to Amsterdam, one friend hosted me for one day and we went out in the snow to meet other friends who were around because of FOSDEM. I still have amazing memories of this day. Next day I met my wife and we went to visit another friend, who hosted us for a few days. They were amazing hosts too. Even went with us to see some places too. No places to recommend here, but I'm quite happy with how things happened. Transport</h2> We used trains and trams a lot to navigate the city. I got one of their cards and just topped it up whenever needed. I had a problem with one of the top ups in the a random machine on the streets, but other than that, nothing to complain. Places</h2> Many places to recommend on this trip. The Anne Frank Museum: I was prepared, as I read the Anne Frank diary before visiting. It was quite interesting to see the place and link with the stories I read. It's a sad and complicated story, but everybody should know it so we can [collectively] never let it happen again.</li> Rijs.. Museum: Amazing museum, totally worth visiting.</li> Van Gogh Museum: It's small and quite different from others. If you're into Van Gogh, it's definitely worth it. If you don't care much, maybe it will not be for you.</li> Red light district: It's quite different than anything I saw before in that lines. Definitely worth a visit. These kinds of things usually make me things on the cultural differences and what is acceptable in different places.</li> Zaanse Chans: That was quite a nice visit. The place is beautiful, and the wildmills are classic Netherlands symbols.</li> </ul> Food</h2> This is not the only place I got this, but I would definitely recommend having some stoopwafels with a hot beverage. :)</li> </ul> Bruges Unknown — Mon, 20 Feb 2017 00:00:00 +0000 In 2017 I had the chance to speak at FOSDEM</a> in Brussels</a>, and I used this opportunity to travel around Belgium a bit, one city every day. One of the cities I visited was Bruges. Everyone I spoke recommended me to visit Bruges, so I decided to go. It was not the city I liked the most, but it's quite nice indeed. A very small city that still looks very medieval. :) Stay</h2> I stayed in a nice hostel with a great location and I really recommend it. Please ping me directly so I can look for it as I don't remember the name and I don't have internet connection while writing this. The location is great, the place is clean, good Wifi, friendly staff (in 2017). Transport</h2> I did everything walking, the city is not that big and I like walking. I got the train to get there from Brussels and I rememebr it took around 1 hour and half. Places</h2> As usual, I did the free walking tour with local guides. Most of the time, it's a great experience I don't regret. It's cheap and fun. I met the guide at the main square around 10. The name of the group of guides is "Legends of Bruges", and I got their info with the hostel folks.</li> I like medieval structures, so I decided to walk around the city to see their portals, they have ~7 of them (if I remember correctly).</li> I climbed the main clock tower and it was a good experience. It's a very small place with tons of steps, so be prepared!</li> </ul> Language</h2> I don't remember which one is their main language. In Belgium they have French and Dutch as the most used languages. Depending on how close you are from France or the Netherlands, you see see more french or Dutch, respectively. I remember going to a place for breakfast and a couple with kids speaking french and the person replying in English, so I tend to think they speak mostly Dutch. Food</h2> Nothing that I remember and it's worth listing. Just cheap food and nice fries. :)</li> </ul> Ghent Unknown — Mon, 20 Feb 2017 00:00:00 +0000 In 2017 I had the chance to speak at FOSDEM</a> in Brussels</a>, and I used this opportunity to travel around Belgium a bit, one city every day. One of the cities I visited was Ghent. Ghent is certainly the city I enjoyed visiting the most in this whole trip. The city itself is quite nice and small and there a nice castle in the middle of it. It is worth mentioning that it was in Ghent that I saw snow for the first time in my whole life. :) Stay</h2> I stayed in a hostel that had a great location, quite close to a famous bridge and cathedral. I would definitely recommend there. The place itself is far from being the best hostel I stayed, but the view is trully something i still remember after many years. Transport</h2> I used the tram to get to the hostel and it worked well, but most of the time I was just walking around. I got the tram because it was quite cold and I was looking for a warmer place. Places</h2> The castle is definitely something worth visiting. I really enjoyed the experience.</li> I did the "Legends of Ghent" walking tour and it was quite nice. I still remember the guide doing jokes with people from Bruges</li> </ul> Food</h2> Nothing that I remember and it's worth listing. Just cheap food and nice fries. :)</li> </ul> Rotterdam Unknown — Mon, 20 Feb 2017 00:00:00 +0000 In 2017 I had the chance to speak at FOSDEM</a> in Brussels</a>, and I used this opportunity to do a bigger travel through a few countries in Europe. After visiting a few cities in Belgium, I went up to Rotterdam. Stay</h2> I stayed in the cube houses, which is a very iconic place in Rotterdam and it's now a hostel! It was an amazing experience and I totally recommend it. Transport</h2> Other than getting the train to get there, I didn't use the transport much, as far as I remember. I spent only one day there, so I didn't need much for what I wanted to see. Places</h2> The cube houses, for sure. It's quite nice, even if you don't want to actually stay there.</li> </ul> Food</h2> Nothing that I remember and it's worth listing.</li> </ul> Review of The Diary of a Young Girl Unknown — Wed, 01 Feb 2017 00:00:00 +0000 Book: The Diary of a Young Girl</a> by Anne Frank. Rating: ⭐️⭐️⭐️. I decided to read this book one month before visiting the Anne Frank Museum in Amsterdam. My plan is to use the whole context of the book to have the full experience when visiting the museum. The book is OK. Most part of it is just what you expect from a diary of a 14 years old girl, even with the whole context implied. There are some interesting parts about what is going on in the war scene outside and how it affects all people living in the secret annex. The historical context of the war can be perceived between one sentence and another. After visiting the museum, things became more vivid. Life in the secret annex was not an easy task. Just living there all the time would be a hard task, but living there knowing that someone may find and kill you at any time is terrifying. This is the kind of book that is becomes much more interesting when you have more context. Visiting the museum brought the context I needed. Review de A história de Kullervo Unknown — Wed, 01 Feb 2017 00:00:00 +0000 Book: A história de Kullervo</a> by J.R.R. Tolkien. Rating: ⭐️⭐️⭐️. Um livro para quem é fã de Tolkien. Esse é um livro relativamente pequeno, com uma história de cerca de 50 páginas e muitas referências para um dos primeiros trabalhos do Tolkien. Eu só recomendaria esse livro para quem já leu outras obras do Tolkien como Silmarilion</a> ou Os Filhos de Húrin. A história de Kullervo inspirou muito do que aconteceu na história de Turin Turambar, além de outras coisas que são contadas no Silmarilion. Para quem é fã é um livro bem legal de se ler, mas para quem não conhece muito de Tolkien vai ser um livro chato e incompleto. Review of Outliers: The Story of Success Unknown — Mon, 23 Jan 2017 00:00:00 +0000 Book: Outliers: The Story of Success</a> by Malcolm Gladwell. Rating: ⭐️⭐️⭐️⭐️. It was a good reading. I would review this book as 3 stars but at the end, I was convinced that it made me think about many interesting things on successful people in general. The key point of this book is: what makes successful people is a match of many factors. Some of those factors were not clear to me. Cultural inheritance is one of those factors. Who were your ancestors? How they lived their life? They probably have some influence on how you lived yours. Dedication is a key point. Many of the outliers present in this book's study had 10000+ hours of practice in their area before becoming successful. Access to the right tools at the right time. To have a computer when most people in the world doesn't can make a huge difference on your success rate, for example. Bill gates is an example of that. My expectation for this book was pretty high, that's the reason for the first sentence of this review, but it is a good book. Here are my notes about the book: 10000 hours of practice. 3 hours a day for 10 years</li> After 100-130 of IQ the difference doesn't matter</li> Practical intelligent. Express your thoughts to others in a convincing way. Say what you have to say, in the right way and the right time</li> Family background makes a lot of difference on the kid success. Access to books and education.</li> Family, ability and personality to get a job. Who has more of these qualities have more chance of getting a job.</li> Do a work that is meaningful</li> Talent, Dedication and timing</li> Success is the combination of many things. Being in the right moment, a dose of talent, a lot of dedication and opportunity. It's not some random thing.</li> Cultural legacy matters. We can't make sense of the world without them</li> PDI power distant industry. Low PDI tends do hide power to exercise it.</li> Highest PDI in pilots were found in Brazil.</li> Book "remember since" Chinese numbers in 2 seconds.</li> Outliers are the result of a lot of work, luck, social context and many other things.</li> </ul> Review of The Memory Illusion: Remembering, Forgetting, and the Science of False Memory Unknown — Wed, 18 Jan 2017 00:00:00 +0000 Book: The Memory Illusion: Remembering, Forgetting, and the Science of False Memory</a> by Julia Shaw. Rating: ⭐️⭐️⭐️. The whole point of this book is to show that our memories are not reliable. We can't be sure that something happened because a lot of things may influence our past memories. The good argument in favor of this book is its references. There are many references for academic studies. The bad part is that it is not so comfortable to read, the language is not that good. In the end, you will learn some interesting facts about how your memory work. For some reason I took notes in pt-BR for this book. I'm not going to translate them (as usual), so here are my raw notes for this book: Se você acordasse sem memória, sem lembrar de nada e sem saber fazer nada, você ainda seria você?</li> O vestido era realmente azul e preto naquela imagem</li> A forma como percebemos o mundo, juntamente com o tipo de iluminação que dá a ilusão da cor diferente</li> Pessoas que estão sentindo dor conseguem decorar mais coisas relacionadas com dor do que as que não estão. (State depending memory)</li> Nós vemos o mundo de uma forma nossa, não como ele realmente é</li> Nossas memórias, mesmo as mais claras, geralmente são diferentes do que aconteceu na realidade</li> Se você fazer a mesma coisa repetidamente, você cria uma cadeia de neurônios associados a essa atividade</li> Os neurônios estão ligados em uma rede com várias associações, com isso, é fácil fazer uma pessoa chegar a palavra lei falando de um policial, mas é difícil chegar a palavra mesa, por exemplo.</li> Lembrar de tudo é uma fraqueza, não necessariamente uma vantagem. É bom esquecer as coisar e focar apenas no que é importante para você.</li> Paradoxical sleep. Dormindo mexendo os olhos (também conhecido como REM sleep)</li> Hipnose não existe. Não há pesquisas sérias sobre o assunto segundo a autora</li> Mensagens subliminares não influenciam nossas opiniões. Em formas bem simples elas dão uma dica em alguma coisa, mas é só.</li> Own race bias. A forma de reconhecimento facial muda de raça para raça. As pessoas tendem a procurar traços diferentes naquela raça.</li> Phubbing: ficar com o celular em vez de ficar com as pessoas</li> Vídeos e imagens podem mudar o que vimos. Por serem similares, eles entram nas memórias reais e começamos a considerar como verdade.</li> Digital amnesia. Depender do Google para tudo. Saber que está salvo em algum lugar.</li> Mnemonics. Usar frases para lembrar palavras Never Eat Salthy W... (North east south west)</li> Mind palace. Guardar as coisas em um espaço virtual. Criar um local bizarro ajuda bastante a lembrar.</li> </ul> Review of Algorithms to Live By: The Computer Science of Human Decisions Unknown — Thu, 29 Dec 2016 00:00:00 +0000 Book: Algorithms to Live By: The Computer Science of Human Decisions</a> by Brian Christian. Rating: ⭐️⭐️⭐️⭐️. This is that kind of book that does not answer questions, it just creates a lot more. :) I tend to not implement algorithms just for the sake of learning a new one and this is not a good thing. When you read these kinds of books you understand why it's so important to know which kinds of algorithms already exists and which problems they solve. Real hackers (Read Hackers: Heroes of the Computer Revolution</a>) implement their own code just for the sake of learning something new or for the joy of programming. When you really need to deal with a complex problem, the tools will be already in your mind, just compose and create. This book helps understanding some interesting algorithms that we use (or should be using) in real life. You will understand the basics about them. In case you're a programmer, it will probably generate a list of new topics to study. :) Here is my raw notes about the book: A mention to the secretary problem</li> Look to 37℅ before choosing, then choose the best one</li> To decide the total amount look at the total time you can spend with that search</li> A/B testing is a good explore exploit example. Look for data then explore it.</li> Base rule</li> Laplace rule</li> Gauss curve</li> It's important to live with reliable adults. That could influence the [[marshmallow experiment]].</li> "Basyan protect your prior"</li> 9 factor model</li> Sorting is a big computing problem that we use in our daily life</li> When you just have one computer and the tasks do not depend on one another, it doesn't matter the order you do them, they will always be finished at the same time.</li> complexity penalty</li> Problem relaxations: constraint relaxations. Traveling salesman, remove the need to not pass in the srme city moase than once</li> Continuous relaxations: transform binary or discrete into continua. When choosing between two choices use a 50-50 chance.</li> Langrange relaxation: violate the rules and add penalties.</li> Gredy algorithm? Traveler salesman</li> Hill climbing algorithm</li> A connection doesn't exist in the internet, it's just a concept.</li> Exponential backoff</li> AIMD algorithm (opposed to "up or out")</li> Backchannel in a conversation</li> Being a successful investor is anticipating the antecipation of others</li> The optimist proclaims that we live in the best of all possible worlds; and the pessimist fears this is true</li> The prisoners dilemma. It's always better to blame your partner.</li> The paradox is that if all partners blame each other, it will be bad for everyone</li> Every time you find yourself in the side of tne majority, it's time to pause and reflect</li> Use other people's opinions as part of your thoughts but do not use theirs only.</li> Recursion in poker. You never play your hand. It's your hand, what you think the opponent has, what the opponent think you think it has and so on.</li> Help people to not have to compute things to be able to understand you</li> Say what you want instead of giving clues about it. To let the person simulate your needs is costly and usually doesn't generate good results.</li> Do not delegate your problem to someone else</li> Whenever you give a choice, reduce the number of items to make it easy for the one choosing.</li> </ul> Review de Introdução à Web Semântica: A inteligência da informação Unknown — Sat, 24 Dec 2016 00:00:00 +0000 Book: Introdução à Web Semântica: A inteligência da informação</a> by Diego Eis. Rating: ⭐️⭐️⭐️⭐️. Tive o prazer de ajudar no processo de revisão desse livro. O assunto sempre me chamou a atenção mas nunca parei para estudar e entender as necessidades. Esse livro vai desde o começo da internet, mostrando as outras tentativas de implementação e como chegamos na forma de mostrar dados que temos hoje. Essa forma possui alguns problemas para dar contexto para as coisas e fazer os links entre os conteúdos, e é aí que entra a web semantica. O livro me ajudou a entender os problemas atuais e como estamos seguindo para resolvê-los. Se você está começando agora suas pesquisas na área, esse livro vai te poupar um bom tempo e te dar vários ponteiros para futuras pesquisas. Se você só está curioso sobre esse lance de web semântica esse livro vai ser o suficiente para entender o que cenário atual. :) Review of Programming Elixir: Functional |> Concurrent |> Pragmatic |> Fun Unknown — Fri, 16 Dec 2016 00:00:00 +0000 Book: Programming Elixir: Functional |> Concurrent |> Pragmatic |> Fun</a> by Dave Thomas. Rating: ⭐️⭐️⭐️. It's not the best Elixir book I read but it's a good book. I started with Programming Phoenix for a more practical learning. This book feels like the other "Programming language book". You will find how to split a string, or how you can deal with regex. In case you're looking for the methods for many types, it will be for you. For me, it's not the best book to start, but it's a good one to improve your skills and "programming language vocabulary". Review of The Subtle Art of Not Giving a Fck: A Counterintuitive Approach to Living a Good Life Unknown — Fri, 09 Dec 2016 00:00:00 +0000 Book: The Subtle Art of Not Giving a Fck: A Counterintuitive Approach to Living a Good Life</a> by Mark Manson. Rating: ⭐️⭐️⭐️. It was good at the beginning but the end was too self-help for me. I learned good things in this book and that's what matters for me. Here are my raw notes about the book: Give a fuck about things you already have, not only what you want.</li> We have a limited number of fucks to give, choose yours wisely.</li> If you're giving a fuck to a lot of things is because you're lacking important things to give a fuck</li> Everyone wants the good parts of life (playing in a band and being a rockstar) but nobody wants the difficult part (countless hours playing your guitar alone and working on band's marketing). Fail is the way forward.</li> Your actions are guided by your values, think about them and define good values for your life.</li> Set good metrics for yourself. The example of Dave Mustaine is really great. Mustaine is awesome but he always compares his band with Metallica. He may have better metrics than that.</li> Take responsibility for your feelings. You can't control other people's feelings, but you can control your own.</li> The point of democracy is to deal with people we don't like</li> We don't praise enough people we like and praise famous people that don't deserve it</li> Michael Jordan failed multiple times so succeed</li> Improve your values and your metrics. Your life will blow away, everything will change but you will feel better</li> You can't control other people, but you can control your feelings</li> You are wrong about everything. Question yourself whenever possible</li> Fail is the way forward. Everyone talks about success but noone talks about the huge amount of failure to get there.</li> Give yourself the chance to fail and improve. If you don't know what to do, try it anyway and the ideas will come to your mind.</li> Traveling is a good way to grow. You will understand how people live with different values and are happy with that.</li> Uma teoria sobre o porque das pessoas serem honestas na Russia é o comunismo. Lá você precisa acreditar nas pessoas e a honestidade é muito importante para o sistema. No capitalismo, se você se apresentar de outra forma, que não precisa ser honesta, talvez seja melhor para ganhar ou vender coisas.</li> </ul> Review of TED Talks: The Official TED Guide to Public Speaking Unknown — Fri, 02 Dec 2016 00:00:00 +0000 Book: TED Talks: The Official TED Guide to Public Speaking</a> by Chris J. Anderson. Rating: ⭐️⭐️⭐️. There are some cool tips in this book but it's not so straight to the point if you're just looking for speaking tips. If you like to speak at IT events (like I do) I really recommend http://speaking.io</a>. This book shows the way to deliver a presentation that earns a standing ovation at the end. It makes sense, that's TED. So, if you're passionate about TED's way of presenting or want to speak at TED someday, this book will be great for you. It's a good book, I got some interesting insights about public speaking, but it was less than I was expecting. Three stars: Good book, but be warned. :) Here are my notes for this book: Give, not take. Your presentation should not be a sales pitch, it should give knowledge to the attendees.</li> To not waste the audience's time. Don't say you're not prepared for the talk or was just thinking about what to say some minutes before.</li> Inspiration can't be performed</li> Answer the questions: what, so what, now what</li> Search for the checklist of the chapter 5.</li> Connection: be personal. Speak their language. Make eye contact.</li> If you're nervous, show it, the audience will be with you</li> Ask a question to spark curiosity, then go to the explanation</li> Use metaphor whenever possible. JavaScript async pants and underwear</li> Use arguments like reduce to absurd when trying to get the audience to understand your point</li> Wondertalk. Show awesome images and concepts to demo your idea</li> Find fantastic arguments, like said in the "man to the moon" speech</li> Use question slides and answer while speaking</li> If your slides is not about what you're talking, remove it from there. A black screen would be better to not get the attention from the public.</li> Avoid using pictures of you or your team. Focus on the audience, not yourself. Use them in case it makes sense to tell the story.</li> Make a good planning for the starting and ending of your presentation.</li> If your talk was a novel, how would you start it?</li> You don't need to walk. Just stand tall and use your arms to amplify what you're saying.</li> If you decide to walk, do it intentionally or you will look nervous.</li> To speak fast is better than speaking too slow.</li> Make eye contact</li> Be personal</li> Show your vulnerabilities, so you may look like one of them</li> The five steps. Start with something everyone cares about and bring them all to the same scene. Create curiosity, make them think on the "Why's" and "How's" of what you said. Go on your concepts, one by one. Now, use a big metaphor to help them understand on different terms. And finally, use real life examples.</li> Use images that says what is difficult for images to say.</li> At least one third of the most viewed TED talks do not use slides at all</li> Avoid all black or white clothes in case your talk is being video recorded. These monochrome colors tend to make you disappear or shine depending on the background.</li> </ul> Review of Will It Fly?: How to Test Your Next Business Idea So You Don't Waste Your Time and Money Unknown — Sun, 13 Nov 2016 00:00:00 +0000 Book: Will It Fly?: How to Test Your Next Business Idea So You Don't Waste Your Time and Money </a>. Rating: ⭐️⭐️⭐️⭐️. I like this book and have a bunch of notes to share. Here are my raw notes about the book: Grab a piece of paper and divide it into four sections. Then, identify the four most important parts of your life. Your categories might be, for example, Family, Career, Well-being and Money.</li> If, during this process, you start to think that your idea won’t generate enough money to make this scenario realistic, set aside time right now to improve it.</li> Is there one thing that you’re exceptionally good at? If so, you should learn to use it to your advantage!</li> Do brainstorming. A mind map may be a good tool</li> The next step is to distill your idea into a single cohesive sentence that helps you pare it down to its essence. Then, once you have categories, write 400 to 500 words that cover them all.</li> What’s in it for me? Get your entrepreneurial idea ready for take-off.</li> Becoming a successful entrepreneur means creating a business that’s in line with your lifestyle goals.</li> Successful entrepreneurs spot their advantages by looking to the past.</li> Map your idea and distill it to its essence.</li> Share your idea, ask for feedback and research your market.</li> Understand your audience’s issues and how they describe them.</li> Strengthen your idea by collecting customer anecdotes and tuning into their needs.</li> Smart entrepreneurs test the commitment of their potential customers and investors.</li> Final validation comes through interacting with potential customers and inviting them to invest.</li> Share your idea, ask for feedback and research your market.</li> OK, now your idea is in a shareable format, but before you launch your business, it’s essential to research how the world will respond to it.</li> Your idea will be improved by sharing it and learning from the feedback. In fact, even casual chats at work or at home can lead to valuable feedback that can help you refine your concept. But you must also be sure to speak with potential clients.</li> For instance, the author had the idea to build a website for people who want to run food trucks and started contacting people who already had food truck businesses. The food truck owners immediately asked him if he owned a food truck – and he would reply that he didn't.</li> This experience forced him to think more closely about his idea and why somebody would take his advice if he wasn't in the business. Eventually, this reflection led him to reshape the idea entirely, branding himself as a curator of a community for food truck owners.</li> The next step is to determine how your market currently operates and attempt to add a new dimension to it. A good tool for doing so is a market map.</li> To make one, just create a spreadsheet with different pages for places, people and products.</li> Your customer PLAN stands for your customers’ problems, language, anecdotes and needs. To get started on yours, add a page to your spreadsheet called P.L.A.N. and make four columns, one for each of the above categories.</li> Identify problems. Talk with the people you listed and ask questions about what you're planning to do.</li> Understand how those people speak and enter in their world. Speak like yours customers, become one of them.</li> Catch your customers anecdotes (stories) and learn about them. Interesting stories will make you think about your product.</li> Be heard. Talk about it, write about it for free and get people's attention.</li> </ul> Review of The 10x Rule: The Only Difference Between Success and Failure Unknown — Fri, 11 Nov 2016 00:00:00 +0000 Book: The 10x Rule: The Only Difference Between Success and Failure</a> by Grant Cardone. Rating: ⭐️⭐️⭐️⭐️. I really like this book. I would recommend it if you are the kind of person that wants to make a difference in the world and want to be remembered in the future generations. The book will not give you that but if you follow a methodology like it recommends you will get closer to your big goals. Here is my raw notes about the book: Always multiply your goal by 10. You will have to think differently about the problem when you do that. By having such a big goal, you will need to attack it with massive action.</li> Don't worry about what the society thinks about you. Most people decided to be mediocre (part of the average people, and that's ok) and they will criticize you because you're not "living your life". Just remember that success is your duty.</li> Fear is a good thing, it mean you're going to learn new things and conquer new places. Don't be afraid to do things.</li> Forget about excuses, it will just give you a reason to "be on average". Instead of using excuses, do what have to be done.</li> Don't be a victim. Will you add to your CV: "I am a programmer and part-time victim?". Will you teach your kids how to be a victim? So don't act like one.</li> You are the problem and the solution</li> Never change your goals for less in case you find that you are not ne able to reach them. There is no problem in no reaching your goals.</li> Mass action. You will be weird for many people that are mediocre, but your efforts will totally worth it.</li> Working for a burger company was not good for him. Not because of the money, but because it was not aligned with hes goals. A friend of his were just ok with the job, because it make sense for his future.</li> Write down the people you know that live on average and the ones that are really good on what they do. What is the difference?</li> Don't be competitive, be dominant</li> Fear is a good thing. Be scared to not have fear of something</li> Wake up! No one will save you. You must do it for yourself.</li> There are no excuses. Do not use them. Make it happen. Car traffic? Leave earlier</li> To do something big you have to take risks</li> Have courage. Courage is for those who act</li> </ul> Review de Guia Front-End: O caminho das pedras para ser um dev Front-End Unknown — Tue, 01 Nov 2016 00:00:00 +0000 Book: Guia Front-End: O caminho das pedras para ser um dev Front-End</a> by Diego Eis. Rating: ⭐️⭐️⭐️⭐️. O Diego Eis está aí desde a época que usávamos tabelas para construir sites, é sempre interessante absorver conteúdo de pessoas com tanto histórico. O livro não foi escrito para o meu perfil, mas mesmo assim me fez pensar em umas coisas interessantes. Ele me fez realizar o mundo sem CSS para criação de páginas, onde você precisava colocar o estilo em todas as tags, sendo que as tags que estão dentro dela não herdariam o estilo. Chega a ser bizarro pensar nisso hoje em dia. Esse livro foi escrito de um ponto de vista bem pessoal, mostrando o que o Diego Eis usa e recomenda para quem está começando na área. Se você quer trabalhar com frontend e está no início de carreira, você vai encontrar várias dicas boas e indicações de onde continuar procurando. Review of Einstein: His Life and Universe Unknown — Thu, 27 Oct 2016 00:00:00 +0000 Book: Einstein: His Life and Universe</a> by Walter Isaacson. Rating: ⭐️⭐️⭐️⭐️⭐️. This is the first biography that I read and I found it amazing. I knew that Albert Einstein was a genius but it was not just that. He was extremely devoted to what he did. I had many quotes from this book and one of them shows what I just said: "As long as I am able to work, I must not and will not complain, because work is the only thing that gives substance to life" That was after his second wife died and he was back to the office, still sad. He had one of the attributes that I wish to have more: the ability to concentrate everywhere. There are many examples of his ability to concentrate in this book. Some of them are in really crowded and noisy places. His level of concentration is so high that, on one occasion, he was receiving a standing ovation and did not noticed until his friend poked him. There is much information about Albert Einstein available on the internet, but I had a really different view of him before reading the book. So, I really recommend you to read this book if you want to know more about this fascinating person. I was not used to take notes at the time and this book was probably my first serious take on this, so all my notes are in pt-BR. I will post them here anyway: Abrahan, ia ser seu nome, mas era "muito judeu" 🙄</li> Einstein era discriminado na escola por ser judeu e diferente do resto</li> Ele usava música para pensar. Tocava violino, no estilo Sherlock Holmes.</li> Não era muito sociável e não se preocupava com os sentimentos das pessoas</li> Ler muitos livros científicos o levou a pensar que a Bíblia não pode ser verdade.</li> Ele começou a ter aversão a qualquer dogma ou entidade "sabe tudo". Só sua presença na sala de aula tirava o respeito do professor. Isso o ajudou a enfrentar a física e propor suas ideias.</li> Ele sempre esquecia as chaves e outras coisas. Chegou a virar piada.</li> Ele só se saia bem nas matérias que lhe interessava</li> Teve uma namorada que fazia tudo com ele, inclusive estudar.</li> As visualizações dos experimentos era o que mais o diferenciava</li> Quando algo não era interessante ele se saia mal, fazendo de qualquer jeito.</li> Ele dizia sobre o amigo: não tem ninguém que me conheça tanto.</li> Seu amigo morreu apenas algumas semanas depois dele</li> Você sabe o que você ta comendo? Esse é o famoso caviar! Einstein: se você der comida gourmet para alguem como eu, você sabe que essa pessoa nao vai apreciar.</li> Deus não joga dados: Baseado na crença de Baruch Spinoza, Einstein acreditava em um Deus deterministico que não deixava as coisas acontecerem aleatóriamente, mas que mantinha tudo em sua devida ordem. Tudo de acordo com as leis da natureza, mesmo que a física quantica dissesse o contrário.</li> Einstein lançou um paper que revolucionou a física mas ainda não era doutor, porque as suas propostas não tinham sido aceitas</li> Ser doutor não lhe trouxe nenhuma vantagem acadêmica, mas pelo menos podia ser chamado de Doutor Einstein</li> O tempo tem que ser inserido na constante porque a luz é sempre observada por alguém e tem uma velocidade fixa</li> Einstein chegou a sua primera versão da teoria depois de conversar com seu amigo</li> Muito das coisas que ele fez foi graças ao seu trabalho com as patentes</li> Negaram o Einstein, porque era Judeu e não austríaco. O outro candidato achou um absurdo e desistiu da vaga.</li> Teve que escolher uma religião aleatória porque todos os professores tinham uma.</li> Tinha 3 cidadanias com 32 anos.</li> Antes de se separar, ele já se considerava sepadado, porque sua ex esposa resistia o divórcio. Ele considerava sua esposa como "um funcionário que eu não posso demitir"</li> O astrônomo que fazia a primeira tentativa de provar a curvatura da luz pela gravidade, foi passar sua lua de mel na suíça. A reação da sua esposa por usar parte da sua lua de mel para ficar junto com físicos teóricos que ela nunca viu, não foi registrada.</li> A primeira tentativa falhou devido a primeira guerra mundial. A Alemanha declarou guerra a Russia e os astrônomos que estavam na Russia foram pegos e tiveram seu equipamento confiscados. Não conseguiram provar que cameras e equipamentos de alta precisão estavam lá para registrar a curvatura da luz no espaço.</li> Elza, a nova esposa do Einstein, não se importava com matemática ou com a teoria da relatividade. Eles nunca tiveram uma relação muito próxima e dormiam em camas separadas. Ela se sentia feliz em cuidar dele e garantir que ele conseguisse fazer as coisas que o deixavam feliz, como seu trabalho.</li> Essa é uma estrela bem pequena. Tem estrelas muito maiores e mais importantes que devem estar vivendo melhor.</li> God do not play dice</li> Mudança do Einstein para os EUA. Ele foi trabalhar em um instituto ligado a Princeton. O cara que o recrutou perguntou o salário e ele disse $3000. O cara pareceu surpreso, e então Einstein pergunta se dá para viver com menos. Ele acaba indo ganhando $10000 e aumentando para $15000 pouco depois.</li> Einstein ligou para a universidade para falar com um amigo e perguntar onde ele morava, porque tinha esquecido.</li> Teve uma vez que alguém ligou na Universidade que ele trabalhava querendo falar com uma pessoa. O cara falou que essa pessoa não estava, então ele pediu o endereço do Dr. Einstein. É claro que essa informação não poderia ser passada, aí ele falou: "Não conta para ninguém, mas eu sou o Dr. Einstein, estou indo para casa e esqueci onde fica"</li> Uma vez ele estava em um evento e se distraiu escrevendo equações em seu caderno. Em um determinado momento o pessoal estava aplaudindo de pé. O amigo dele cutucou ele e pediu para ele levantar. Ele levantou mas ainda perdido em pensamentos, sem entender. A salva de palmas era para ele.</li> É difícil focar após a morte da Elza, mas enquanto eu puder trabalhar eu não vou me preocupar, porque trabalho é o que dá sustância para a vida.</li> Um cara que sabia por onde ele passava ficou esperando para poder falar com ele. Einstein disse que podiam conversar, mas só sobre matemática, nada pessoal.</li> Einstein morreu ainda escrevendo suas últimas equações tentando encontrar a teoria unificada.</li> </ul> Review of Programming Phoenix: Productive |> Reliable |> Fast Unknown — Sat, 15 Oct 2016 00:00:00 +0000 Book: Programming Phoenix: Productive |> Reliable |> Fast</a> by Chris McCord. Rating: ⭐️⭐️⭐️⭐️. It is a great book for web developers learning Elixir (yeah, not just Phoenix). I'm on the path of playing with Elixir and was looking for a book to amplify my knowledge. I first started with Programming Elixir, from Dave Thomas but I was looking for something more practical. I decided to try Programming Phoenix and found that it shows everything I need to know about Elixir to build a web application. For me, it was really great to start with this one. Now I know what needs to be done to build a web application and I can go back to programming Elixir to do a deep dive in the language. Review of The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win Unknown — Wed, 05 Oct 2016 00:00:00 +0000 Book: The Phoenix Project: A Novel About IT, DevOps, and Helping Your Business Win</a> by Gene Kim. Rating: ⭐️⭐️⭐️⭐️. This is a great book for IT folks. In case you worked (or still work) in a big company with lots of ITIL things that holds the development, this book will be like home for you. It is a typical hero's journey and the characters are not so well developed (IMO) but the story is still good to follow. I've created many ideas for the ending and none of them were true, it made me give credits to the authors for not make it obvious. The book is a fictional novel but it has some truth in it. ;) Here are my raw notes about the book: Improve daily work is more important than doing daily work</li> Improvement kata - daily improvement</li> </ul> Escrevendo o Desconstruindo a web Unknown — Mon, 03 Oct 2016 00:00:00 +0000 TL;DR: Escrevi um livro em 315 horas, geralmente aos fins de semana durante 2 ou 3 horas consecutivas. O processo completo durou 8 meses e foi lançado oficialmente na Rubyconfbr2016. Como muitos já sabem, eu lancei um livro chamado Desconstruindo a web</a> pela Casa do Código</a>. Eu sou meio maluco (retardado, segundo o George Guimarães</a>) por produtividade e organização pessoal e resolvi escrever sobre como foi o processo e mostrar todas as métricas que eu coletei. Como começou</h3> Há muito tempo atrás, por volta de 2010, eu participei do DevInSampa</a>. Esse era um evento muito legal que não era focado em uma tecnologia específica e tinha como única finalidade trazer vários assuntos legais da área de desenvolvimento. Nessa época, eu pensei em fazer uma palestra que mostrasse tudo que está acontecendo no computador enquanto você acessa uma aplicação. Quando comecei a fazer um documento sobre isso, percebi que eu teria muito trabalho pela frente e comecei a procrastinação. Fiquei bastante tempo nesse estado... Demorei tanto que o DevInSampa morreu no meio do caminho. :( A procrastinação durou até o meio do ano de 2015, quando o Bruno Costa</a> me chamou para palestrar no DevInSantos</a>! Até o nome do evento era parecido, era uma segunda chance para fazer a palestra perdida. Após aceitar o convite e dar um tema aleatório, eu comecei a fazer as pesquisas sobre o que eu poderia falar. Essa pesquisa me levou a conclusão que mostrar tudo que acontece em uma requisição web seria uma boa ideia. Depois de pensar um pouco, o melhor tema que eu consegui foi "Desconstruindo a web". Depois de algumas semanas fazendo os slides e pouco mais de 40 horas de pesquisa, eu finalmente terminei os slides da apresentação. Ao terminar, percebi que havia muito conteúdo para uma palestra de 50 minutos. Eu que sempre preferi que as palestras tivessem apenas 30 minutos, agora estava reclamando que o tempo não era o suficiente para o conteúdo. Isso me fez pensar que talvez essa não fosse a mídia correta para expor todo esse conteúdo. Fiz a palestra e a recepção foi boa, mesmo com a velocidade alta que eu tive que falar para terminar a palestra a tempo. Apesar disso, saí do evento convicto que eu precisava de outra mídia para passar tudo que eu tinha estudado. E foi aí que uma velha ideia voltou para a minha cabeça: "E se eu escrever um livro?" A ideia</h3> Escrever um livro é um objetivo de vida para mim, portanto eu sempre estava pensando em como atingi-lo. Uma das ideias era escrever um livro de fantasia usando self-publishing</a> em algum momento da vida, mas depois de ver a quantidade de conteúdo que a palestra gerou, surgiram algumas ideias. O conteúdo já estava estruturado e eu já tinha ideia de quase tudo que queria mostrar, bastava colocar em palavras e imagens. Consegui entrar em contato com o Adriano Almeida</a> da casa do código por indicação do meu amigo Vinicius Baggio</a> e apresentei o material que eu já tinha e as ideias para o que ele poderia ser. Ele gostou do material e me passou as condições para continuar o trabalho. A preparação</h3> Nessa época eu estava começando a trabalhar em um projeto freelancer para uma empresa de fora do Brasil, além do meu trabalho em tempo integral para a Locaweb</a>. Eu precisaria organizar o meu tempo para trabalhar no livro, além de manter essas atividades. O único tempo que eu tinha eram algumas horas durante o fim de semana. Com isso, para trabalhar nesse projeto eu precisaria alinhar com a minha esposa e saber se ela estava comigo nesse meu novo projeto. Depois de combinar com as partes envolvidas e fazer o meu planejamento, era hora de começar! O processo de escrita</h3> Comecei a trabalhar no livro logo no começo do ano, sendo que a primeira versão do prefácio foi escrita no dia 9 de Janeiro. Eu mantive uma planilha no Google Docs</a> para contabilizar todas as horas que eu trabalhasse nele. Lá eu também registrei o que eu estava fazendo durante as horas que eu estava trabalhando. A planilha era uma forma bem simples de eu guardar um log do que eu estava fazendo. Simples assim: O último dia de trabalho registrado na planilha é 14 de Agosto de 2016, que é o dia que eu considero terminados todos os trabalhos relacionados ao livro. Por ter essa planilha, eu consigo fazer alguns gráficos interessantes. A partir de agora, vou utilizar os dados que eu extraí de lá para mostrar mais sobre o processo de escrita. Dias trabalhados</h4> A maior parte do tempo que eu escrevi foi nos finais de semana, que somam 50% do trabalho no livro. Minha ideia era trabalhar cerca de 3 horas consecutivas no livro. Essa quantidade de horas é o máximo que eu consigo trabalhar em total concentração. Eu sempre busquei ambientes livres de distração, mas depois de ler o Deep Work</a> (que eu recomendo para todos!) eu melhorei ainda mais a minha forma de trabalhar. Sempre que começava a trabalhar, eu avisava a minha esposa que eu ficaria incomunicável por algumas horas. Durante as próximas 2-3 horas, não haiva comunicador, e-mail, celular ou qualquer outra coisa que pudesse tirar a minha atenção. Eu tenho uma playlist no Google Music</a> só com músicas que me ajudam na concentração. Quando não estava usando essa playlist, eu usava apenas barulho de chuva com o site rain.today</a>. Quem me conhece sabe que eu não sou de comprar fones de ouvido caros, portanto eu tenho um fone vagabundo e uso sons desse tipo para me isolar do ambiente. Horários que eu trabalhava</h4> O horário que eu mais iniciei foi as 18 horas. Geralmente aos domingos, era o momento que eu já tinha aproveitado uma boa parte do dia com a minha esposa e trabalhava até começar o episódio de Game of Thrones na HBO. :D Mas tem início em quase todas as horas do dia. Horas por dia</h4> Esse gráfico foi um pouco assustador para mim. Durante o feriado de Corpus Christi, que aconteceu no dia 26 de Maio, eu estava sozinho em casa e aproveitei para trabalhar no livro. Em um dos dias desse "feriado prolongado" eu trabalhei 12 horas no livro, que está representado como aquele ponto entre 26 de Maio e 12 de Junho. Durante essas datas, eu só sai de casa umas 2 vezes para comprar comida, o resto do tempo foi pesquisando e escrevendo. Eu não tinha nenhum deadline, apenas a vontade de pesquisar e escrever. Isso me fez pensar que eu tenho sorte de ser casado, porque senão eu seria mais maluco que o normal. Horas por mês</h4> Eu estava bem curioso para saber como foi a distribuição de horas durante os meses. Como eu esperava, o mês de Julho tem uma grande quantidade de horas. Isso aconteceu porque eu decidi mandar para a Rubyconf a palestra que inspirou o livro, e ela foi aceita. Esse fato colocou um deadline no livro. :) Após conversar com a Casa do código</a>, combinamos que eu precisaria entregar o conteúdo até o dia 7 de Agosto para que o livro ficasse pronto a tempo da conferência. Durante os fins de semana do mês de Julho eu trabalhei cerca de 14 horas por fim de semana escrevendo. Apesar de ser um pouco cansativo, eu estava bem feliz por estar trabalhando no projeto e não me desgastei muito. Como o prazo era relativamente apertado, eu decidi tirar horas na semana para fazer isso também. Com essa escolha, eu precisei negociar umas "férias" do projeto que trabalho como freelancer e que toma cerca de 2-3 horas diárias do meu tempo. O que compõe a escrita de um livro</h4> Eu sempre tive curiosidade da quantidade de tempo que um escritor gasta nas atividades de escrever um livro e me usei como cobaia para entender um pouco. Escrever é só uma das atividades de um escritor, assim como digitar é só uma das atividades de um programador. Apenas 42% do tempo foi gasto organizando as palavras e escrevendo da melhor maneira possível. O tempo de pesquisa está bem ligado com o tempo de escrita, consumindo 12% do tempo total. Infelizmente eu não separei exatamente a quantidade de horas que eu gastei com pesquisa, portanto, é possível que parte do tempo considerado como escrita também seja pesquisa. Eu aprendi muito no processo! :) Eu decidi fazer todos os desenhos, o que tomou 7% do tempo. Eu não sou muito bom com desenho, mas fiquei contente com o resultado final. Eu utilizei muito Inkscape</a> e um pouco de GIMP</a> para trabalhar com as imagens do livro. Para a imagem do "mapa", que é meio "quem é esse Pokémon?", eu criei um script Python que usa Cairo</a> e rsvg</code> para manipular os gráficos SVG</a> do Inkscape e gerar as imagens na sequência que eu esperava. Era importante criar um site para o livro, pois todo o estudo é baseado em uma URL. Por esse motivo eu gastei 6% do tempo na criação dessa página. Não foi um processo complicado, mas eu queria que ficasse exatamente como eu esperava. Outra dúvida que eu tinha era sobre a reescrita de conteúdo e eu descobri que os primeiros capítulos geralmente são reescritos. Utilizei 6% do meu tempo para reescrever os primeiros capítulos, que já não pareciam com a continuação do livro. Só é preciso saber a hora de parar, senão fica igual refactoring infinito de código. Revisão é uma parte importante do processo e consumiu 25% do tempo total. Eu chamei 4 revisores técnicos competentes para me ajudar no processo (obrigado novamente Milhouse</a>, Daniel Sousa</a>, Mateus Linhares</a> e Vinibaggio</a>) que sempre me davam suas opiniões sinceras sobre o conteúdo. Além disso eu contei também com uma revisora da casa do código, que acompanhou a escrita de cada capítulo e me dava dicas sobre a escrita e didática. Eu resolvi pegar uma semana de férias antes da entrega do livro para trabalhar nele em tempo integral. Ele já estava completo e durante essa uma semana eu trabalhei em revisão. Essa revisão não era igual as que foram feitas durante o processo de escrita e sim uma revisão geral para ver se o conteúdo não estava duplicado entre os capítulos e se estava sendo mostrado de uma forma coesa. A entrega</h3> Eu mantive o livro em segredo durante todo o processo de escrita. Apenas um grupo seleto de pessoas sabiam que eu estava escrevendo, para evitar expectativas. Minha meta era publicar o livro na Rubyconf no dia 23 de Setembro, no final da minha palestra. A casa do código colocou no site deles no começo do mês, mas não divulgaram em nenhum lugar. Alguns amigos descobriram e eu pedi para não divulgarem por enquanto. Ver o livro no site deles e não divulgar foi algo bem difícil, mas eu consegui me conter até o dia 23. Depois da minha palestra eu mostrei o livro e foi uma sensação fantástica mostrar para todos os amigos um trabalho que eu tanto me orgulho. Foram 315 horas e 8 meses de trabalho que valeram a pena. Conclusão</h3> Não escrevi esse livro com a finalidade de ganhar dinheiro. A primeira dica que um amigo me deu quando eu disse que ia escrever foi: "Você sabe que financeiramente não compensa, né?". É sempre bom ter uma segunda renda para remunerar essas 315 horas investidas, mas não foi o principal motivador da minha escrita. Pode parecer bobo, mas eu escrevi esse livro por que eu realmente acredito que ele vai ser útil para as pessoas. Esse é o primeiro livro e provavelmente não será o último... Que venham os próximos! :) Review of Level Up Your Life: How to Unlock Adventure and Happiness by Becoming the Hero of Your Own Story Unknown — Mon, 03 Oct 2016 00:00:00 +0000 Book: Level Up Your Life: How to Unlock Adventure and Happiness by Becoming the Hero of Your Own Story</a> by Steve Kamb. Rating: ⭐️⭐️⭐️. This is a good book but it's not for me. I already use many of the tips mentioned in this book and they really work. It makes a good pair with habitica.com, in case you like to play these kinds of games in real life. There are many great references for the nerds out there. This fact can be a motivator to implement the ideas from characters of your favorite stories. If you're a nerd that wants to motivate yourself for new challenges or personal organization, this book may be a good fit. Just be warned that it feels like a self-help book (because it is, maybe :P). Here are my notes for this book (in pt-BR this time): Comece com o chamado para a aventura</li> Sempre vão haver pessoas para te julgar ou desencorajar</li> I know I am weird é uma boa para falar para quem te critica</li> Usa a jornada do herói como exemplo</li> Transformar locais em zonas para quests. Quanto mais longe mais experiência você ganha</li> Defina goals para ir para a academia. Com o tempo você vai ir por que gosta.</li> Fique sempre perto de pessoas de level alto.</li> Procure um mestre Jedi que conheca mueta coisa e seja mestre no que faz.</li> Encontre companheiros Jedi para dividir conquista e se motivar</li> Use o medo como alavanca. Não deixe você recusar uma coisa legal por medo. Nunca recue por isso. (Batman e os morcegos)</li> Viaje com pouca coisa e não se preocupe em planejar muito</li> Prepare o seu corpo para tudo. Mantenha uma dieta boa.</li> Faça sacrifícios se isso te ajudar a chegar na sua meta. Saiba priorizar o que é importante para as surs metas. Sair com os amigos ou escrever seu livro? O que é mams importante para você neste momento?</li> </ul> Rubyconf 2016 Unknown — Mon, 26 Sep 2016 00:00:00 +0000 TL;DR: A melhor Rubyconf que eu participei Nos dias 24 e 25 de Setembro de 2016 aconteceu a Rubyconf Brasil. Assim como eu fiz um post sobre o primeiro Rails Summit que o Akita participou da organização</a>, resolvi também fazer um post sobre a última rubyconf que ele resolveu organizar. Essa Rubyconf teve vários pontos especialmente importantes para mim. O primeiro deles foi logo no início quando o Gilberto Mautner, que é um dos fundadores da Locaweb, mencionou os números do projeto que eu estou trabalhando por lá. Atualmente estou trabalhando em um projeto para melhorar o tempo de entrega das equipes de desenvolvimento. Para que esse projeto seja bem sucedido, nós precisamos rever vários processos e arquitetura de aplicações. O fato dele ser mostrado na introdução da conferência por ser um projeto legal já diz muito sobre o nosso trabalho. O segundo ponto foi a minha palestra, que aconteceu no primeiro dia as 15:45 no andar aberto (os slides estão aqui</a>). Para essa palestra eu estava mais nervoso do que normalmente fico, porque sabia que eu teria que falar bem rápido se quisesse passar todo o conteúdo no tempo que eu tinha. Além disso, essa não era uma palestra normal! Eu fiz o lançamento do meu livro</a> no fim. E esse foi o terceiro ponto importante dessa conferência. O livro estava disponível no site da casa do código</a> desde o começo do mês, mas eu estava aguardando essa oportunidade para divulgar. Foi um mês de expectativa para finalmente mostrar um trabalho que eu me orgulho muito. O quarto e último ponto que tornou essa conferência especial foi ser citado no fechamendo. Essa vai ser a última Rubyconf organizada pelo Fabio Akita</a>. No fechamento da conferência ele mostrou um review dos últimos 10 anos de organização de eventos de Ruby e agradeceu as pessoas que estavam participando desde o começo. Pode parecer bobeira, mas ter seu nome (ou nickname) citado no final de uma conferência com 1200 pessoas é muito gratificante. Eu já sou totalmente a favor dos planos do Akita e já tinha comentado com ele sobre isso há algum tempo atrás. E ele realmente merece um auditório inteiro de pé aplaudindo seu trabalho durante esses 10 anos. Tudo isso fora os velhos amigos que eu pude rever, pessoas novas que eu conheci e coisas que eu aprendi. Algumas pessoas eu conversei e não sabiam que eram as pessoas que eu falava pela internet há muito tempo, só vim perceber depois. Durante esses vários anos de Rubyconf, eu tive o prazer de conversar pessoalmente com 2 core commiters do Ruby, e isso não é uma coisa que temos a chance de fazer com frequência. :) Esse é o espírito da Rubyconf, juntar desenvolvedores que gostam de programar para trocar ideias. Eu considero essa conferência como uma versão grande do que é o Guru-SP</a>. Não sei como vai ser o futuro de conferências como essa. A Locaweb diz que a Rubyconf continua</a>, mas ainda não temos ideia sobre as novidades. Independente do que está por vir, tenho certeza que esse espirito de camaradagem e busca contínua de conhecimento vai continuar. :) Review of The Coaching Habit: Say Less, Ask More & Change the Way You Lead Forever Unknown — Fri, 02 Sep 2016 00:00:00 +0000 Book: The Coaching Habit: Say Less, Ask More & Change the Way You Lead Forever</a>. Rating: ⭐️⭐️⭐️. Read this book in 2016 but never published any review until now (2021, even if the post date is the day I finished the book). I don't have much to say now, but at least I can publish my notes from 2016. Here are my raw notes about the book: Kickstart, AWE (and what else), and Focus - Are the guides for a coach.</li> You want people working with you to feel compensated, not in danger.</li> Every time you say Yes to something, think about what you're saying no.</li> Ask more about the "what" instead of the "why": "What are you thinking?" instead of "Why are you thinking about that?".</li> In recent years, neuroscientists and behavioral economists have gained insight into how humans develop and maintain habits. There are five events that need to occur for a habit to form: cause, trigger, mini-habit, training, and an action plan.</li> Let’s go through each event. A cause is a reason you want to change the current behavior, like wanting to avoid giving advice, as it’s a hallmark of poor coaching. Once you know what you want to change, you identify your trigger – the moments that encourage you to offer advice. When you know your trigger, you’ll be prepared to deal with it.</li> Your mini-habits are the seven coaching questions you’ve learned in these blinks. Practice them as often as possible. That’s your training!</li> Finally, outline an action plan to fall back on when you slip up. Everyone makes mistakes, so you just need to figure out how to get back on track.</li> Importantly, write down your action plan. Your plan could read, “The next time John stops me in the hallway with a question, I’ll ask a coaching question instead of giving advice.”</li> Once you put theory into practice, you’ll develop a solid coaching habit that will stick with you for the rest of your life. Good luck – and happy coaching!</li> </ul> Review of How to Spot a Liar with People Don't Tell the Truth Unknown — Mon, 29 Aug 2016 00:00:00 +0000 Book: How to Spot a Liar with People Don't Tell the Truth</a> by Gregory Hartley. Rating: ⭐️⭐️. I've used the Audible Abridged version for this one. The narration is not good as the other audiobooks I'm used to listen. The book content is not good to follow as well. It is focused on interrogation and this is not my goal for reading it. But it is not all that bad. I got some interesting tips on body language and these kind of stuff. Here is my raw notes about the book (in pt-BR): Use roupas bizarras e anote sobre o seu sentimento quando as pessoas te olharem estranho. Anote também o tipo de olhar.</li> O cara é um investigador do exército. Fala bastante sobre a linguagem corporal e o que rela diz no interrogatório. Alguns clichês como o corpo suar e a mão tremer são mencionados, juntamente com o que causa isso.</li> </ul> Review of Thinking, Fast and Slow Unknown — Fri, 12 Aug 2016 00:00:00 +0000 Book: Thinking, Fast and Slow</a> by Daniel Kahneman. Rating: ⭐️⭐️⭐️⭐️. The concept of system 1 (fast) and system 2 (slow) is really great. For tech folks, the system 1 looks like a cache inside your head. It is the best way to explain it for tech related people, in my opinion. There are dozens of serious research done to make this book happen. They were not made exclusively for the book, but it is really nice to read a book that has strong foundations. Review de Armadilhas da Mente Unknown — Tue, 12 Jul 2016 00:00:00 +0000 Book: Armadilhas da Mente</a> by Augusto Cury. Rating: ⭐️⭐️⭐️. Eu já tinha lido o "Ansiedade - Como Enfrentar o Mal do Século", portanto esse livro não adicionou tanto para mim. Esse livro mostra todos os conceitos gatilhos, janelas, autofluxo e etc. dentro de um romance. A história é ok e chega a ser interessante até perto do final. Na minha visão ficou nítido que a história não é o centro do livro e sim os conceitos que estão envolvidos com ela. Para quem curte conhecer algumas ideias de pensadores clássicos vai encontrar várias referências nesse livro. Review of The Power of Habit: Why We Do What We Do in Life and Business Unknown — Fri, 08 Jul 2016 00:00:00 +0000 Book: The Power of Habit: Why We Do What We Do in Life and Business</a> by Charles Duhigg. Rating: ⭐️⭐️⭐️⭐️⭐️. Read this book for the first time in 2016 and re-read it now (2019). The first time I read it, I did not take notes, so I decided to "properly read/listen" now. I like the number of studies this book shows and how much we understand about our habits by looking at its results. Some of these studies are already debunked by science (like the marshmallow study), but it's still a great book. At the end of the book, the author provides some examples of how you can use the content of the book to apply to your habits. The goal of this book is not to give you a step-by-step guide on how to change your habits, but to show you how they work. Your cues and rewards are unique, and you have to understand yourself to deal with them. I will keep this piece of the review here. I wrote it in 2016 right after adopting my dog: I'm training a little dog now, and it's really impressive to see how we made some habits for him. It became natural for the dog to pee on a specific place, for example. The important part is to keep the same cue, routine, and reward. :) </blockquote> My dog is three years old now. :) Here are my notes for this book: More than 40% of actions people perform every day are not actual decisions but habits according to paper by Duke University in 2006</li> Removing food from the plaza where a group unites was a good way of not keeping them there. When people start to get hungry, they go somewhere else</li> The research was done with Eugene, known as EP in the medical literature</li> The basal ganglia stores habits in the brain</li> The brain is continually looking for ways to reduce effort -- it seems to be the same idea exposed by thinking fast and slow :)</li> Patients with basal ganglia damage can't get basic feelings because they don't understand simple face recognitions (they don't know where to focus)</li> Whin cues come out of order or in a different shape, they are not recognized, and the habit is not started.</li> The cue starts the need for a reward and the craving for the routine to achieve it. That's one of the reasons why cellphone notifications are so difficult to resist</li> Some people say they like to workout because of the feeling of endorphins, others because of the sense of accomplishment when tracking their results -- I'm at the gym now, and I'm not sure what motivates me. Maybe keeping my routine? (PS. I'm not too fond of the gym environment, but it's ok now)... oooh... Got it, it's the audiobooks! :)</li> The breeze by P&G was created as a great product to remove odor. In the end, they found out that no one wants to admit that their house stinks, so there's no cue. They transformed the product into something else that smells good and created another cue at the end of cleaning. Tne product got millions of revenue. -- yeah... In the end, it's all about money.</li> The cravings drive the habit loop. You need to feel the need for something to power the habit</li> A football trainer (buccaneers) applied a habit-changing routine to his players for years. This training made players not think in certain situations, but apply habits instead, which is faster. -- it reminds me about playing drums. Sometimes I don't know how I'm playing, I just start, and the rhythm takes care of itself</li> Belief is important. It doesn't have to be God, but you have to believe that you will get through stressful moments when your routine is not working</li> "Some football teams are not teams; they are just guys who work together" -- saw that more than once but with developers</li> Changing one habit may chain many other reactions and enhancements. Like changing safety may increase profits and communication. One habit change sometimes requires a whole infrastructure change</li> Michael Phelps routine has nothing to do with swimming, but it's related to his success</li> "It may be hard to fire someone who's been working for the company for so long, but not for me. Our values dictated how to act." He fired himself.</li> The director changed named parking spots in the parking lot. Whoever gets to work earlier will get the best spot. Every person matter. -- whatever getting to work earlier, but every person matter makes total sense</li> Studies show that willpower is the single most important habit that contributes to people's success</li> Starbucks had to invest in creating an environment where it would be ok to pay $5 for a coffee</li> Yet another book mentioning the marshmallow study</li> Willpower is like a muscle, and you have to exercise it. It's a finite resource. If you want to do something that requires willpower you better do it in the morning or conserve your willpower for the night</li> It's important so sign children to piano (or anything else) lessons because it teaches them the willpower to study, not just piano itself</li> "We're not in the coffee business serving people. We're in the people business serving coffee", Starbucks former president</li> When people are doing things that require willpower, and they feel doing it for themselves or helping someone else, it is less taxing on their willpower. If they feel they are just following orders, it will require a lot more willpower to get the job done</li> If a company doesn't cultivate habits to build a good culture, it will still emerge but in a disorganized way.</li> You usually turn right when you enter the supermarket</li> Our brain likes to listen to songs that seem familiar, and this is what makes a big hit.</li> If you dress a new something into an old habit, it's easier for people to accept it (hey ya example)</li> Martin Luther King Jr movement was also based on social habits, strong and weak connections, and peer pressure. It was created in a way where many people agreed, and others will feel bad or "against it" if they did not participate (after all, they support it, but some were just not committed enough and could drop it without peer pressure)</li> To political movements to succeed, people have to change their habits. Their identities have to change.</li> Near misses in a slot machine (and possibly other places) are very addictive for the brain, especially for those sensitive to gambling</li> Once you know a bad habit exists, you have the freedom and responsibility to change it. You will be held accountable for it.</li> This book provides a framework to understand how habits work and a guide on how they can be changed</li> To change a habit, find the cue reward, and routine, and then change the routine. Try some alternate routines keeping the same cue and reward. Take notes of your feelings right after the routine and reward. After 15 minutes, are you still craving for this habit? Example: buy a cookie every day. Try to buy different things or buy in different places to find the exact reward you want to have, and then keep the new routine</li> Take notes of your cravings and what's the situation that triggered it: time, action, where, mood, etc. It will help you to identify the pattern</li> </ul> Review of Life, the Universe and Everything (Hitchhiker's Guide to the Galaxy, #3) Unknown — Mon, 27 Jun 2016 00:00:00 +0000 Book: Life, the Universe and Everything (Hitchhiker's Guide to the Galaxy, #3)</a> by Douglas Adams. Rating: ⭐️⭐️⭐️. Nothing special about this one... The first one is brilliant, the second one is great, the third is just OK. This book made me think about reading the fourth and fifth and I think I will stop here. All that moments that make you think about "Life, Universe and Everything" are not present here like was in the first books. Ouvir livros (audiobooks), o futuro da leitura Unknown — Wed, 22 Jun 2016 00:00:00 +0000 TL;DR: Ouvir livros é o futuro. Atualização de 18/06/2016: Adicionando o audiobooks.com</a>. Quem me conhece sabe que há muito tempo eu ouço podcasts sempre que eu posso, principalmente no caminho entre a minha casa e o trabalho. No fim do ano de 2015 eu vi a quantidade de livros que o Rafael Rosa</a> leu e fiquei abismado. Ele leu mais de 90 livros em um ano! Tudo bem que ele estava em um período sabático, mas mesmo assim ainda é uma quantidade bem absurda de livros para se ler em um ano. Ao conversar melhor o Rafael, descobri que boa parte desses livros foram lidos via Audiobooks. Ele, assim como eu, sempre foi adepto de podcasts, mas há um tempo decidiu trocar por audiobooks e falou que estava indo muito bem assim. Eu decidi então que iria tentar um audiolivro em breve para ver se me adaptava. Lembrei que em poucos dias eu teria que fazer um mapeamento de retina, o que me deixaria a pupila dilatada durante quase todo o dia, me deixando sem a possibilidade de fazer muita coisa. Isso se mostrou ser o momento perfeito para testar audiobooks! Resolvi começar com um livro bem antigo chamado: "A arte da guerra". Deixei tudo preparado no meu celular e em uma tarde o livro estava totalmente lido. O livro é pequeno, mas troquei uma tarde perdida por um livro lido! Resolvi então começar uma quest para ler mais livros. Para isso eu precisava de um processo simples e justo de ouvir, portanto testei várias apps. Vou descrever abaixo os meus testes: Audible</a> -- É de longe o melhor serviço que tem para audiobooks. Tem uma biblioteca bem extensa para livros, possui aceleração de audio, a compra e download de audiobooks é bem simples e o site é bem fácil de usar. Um dos problemas é que a grande maioria do livros estão em inglês. Há alguns livros em português, mas somente os livros muito clássicos como "Dom casmurro" por exemplo. No audible, para que você consiga 1 audiobook por mês você paga $15, o que dá quase R$70 para nós no brasil, o que é um valor meio salgado IMO.</li> audiobooks.com</a> -- Uma tentativa de concorrer com o Audible, mas com o mesmo preço e uma qualidade de aplicativo bem inferior. A parte boa é que você pode fazer o trial de 30 dias e ouvir um livro de graça, em último caso, caso você não goste, pelo menos ouviu um livro.</li> Scribd</a> -- Está entrando agora na área de audiobooks. A compra de livros e download do audio foi bem fácil e o serviço possui tanto livros como audiobooks. O player ainda não possui a funcionalidade de acelerar o audio, o que para mim o torna quase inutilizável. O serviço não tem uma biblioteca tão vasta como a do Audible, mas possui vários livros legais. O valor é quase metade do valor do Audible e pode ser uma alternativa assim que implementarem a aceleração de audio.</li> Tocalivros</a> -- É a alternativa brasileira de distribuição e criação de audiobooks. O player deles melhorou muito nos últimos meses e está quase chegando lá. Infelizmente a quantidade de títulos bons ainda é bem baixa e nem se compara com serviços gringos ainda.</li> Ubook</a> -- Esse eu não cheguei a testar para formar uma opinião, mas resolvi colocar aqui como mais um site brasileiro de audiobooks. A quantidade de títulos também é bem precária, no mesmo esquema do tocalivros.</li> </ul> Quando o livro que eu estou lendo não tem narração humana eu vou para a versão sintetizada. Tem gente que abomina a narração sintetizada, mas para mim não é um grande problema, desde que eu consiga entender o conteúdo. Para quem não conhece, a narração sintetizada é quando você coloca uma voz sintetizada como a do Google Translate para ler um livro para você. Essa ideia é muito utilizada por pessoas com deficiência visual, pois não podem depender de alguém narrando para eles todo o conteúdo e fazem a maquina narrar. O que eu uso para narração sintetizada: @Voice</a> -- De todos que eu testei esse foi o que eu mais gostei. O esquema de voz é aceitável e é fácil de ajustar a velocidade. Ele também integra com o Pocket</a> caso você queira ouvir os seus artigos.</li> Lev Saraiva</a> -- O Lev é o leitor da Saraiva e suporta narração sintetizada. A parte boa dele é que você pode comprar os livros direto na Saraiva e integrar com ele. Na teoria é uma ótima ideia mas na prática não funcionou muito bem para mim.</li> </ul> A fundação Dorina nowill</a> para cegos tem vários audiobooks narrados, mas só tem acesso os deficientes visuais que fizerem um cadastro bem extenso e pelo que eu li eles recebem um CD com o audio. Existe uma lei que quem tem deficiência visual não precisa pagar por esse tipo de conteúdo e a fundação pode disponibilizar gratuitamente, mas pelo visto eles fazem um controle legal para manter o copyright e etc. Obviamente, boa parte desse conteúdo está aberto na internet em blogs que acham e disponibilizam, portanto não é muito difícil de encontrar. Caso você siga por esse caminho, seja um bom samaritano e compre os livros para remunerar o autor que gastou centenas de horas da vida dele para escrever o livro que você está lendo... É o que eu faço com os livros que eu ouço dessa maneira, alguns eu até dou de presente. Não é todo livro que é legal de se ouvir, alguns são densos demais para que você consiga compreender bem apenas ouvindo continuamente, mas a grande maioria das ficções é bem agradável de ouvir. Eu tinha colocado uma meta de 10 livros para esse ano, e meu goodreads</a> nesse momento está mostrando que eu já li 22! Fica aí a dica para quem, como eu, ficava reclamando que não conseguia ler os livros que queria! :) Review of The Restaurant at the End of the Universe (Hitchhiker's Guide to the Galaxy, #2) Unknown — Tue, 14 Jun 2016 00:00:00 +0000 Book: The Restaurant at the End of the Universe (Hitchhiker's Guide to the Galaxy, #2)</a> by Douglas Adams. Rating: ⭐️⭐️⭐️⭐️⭐️. Another great book from Douglas Adams. The idea behind the restaurant is really really interenting and the author does a great job to insert funny concepts behind the whole event. There are some nice gotchas that make you laugh while reading, I really recommend it. Review of The Hitchhiker's Guide to the Galaxy (Hitchhiker's Guide to the Galaxy, #1) Unknown — Mon, 06 Jun 2016 00:00:00 +0000 Book: The Hitchhiker's Guide to the Galaxy (Hitchhiker's Guide to the Galaxy, #1)</a> by Douglas Adams. Rating: ⭐️⭐️⭐️⭐️⭐️. This book is amazing! There are some non-sense parts but in general, it makes you think about "life, universe, and everything". There are some ideas that look so absurd in real life but make sense in the book context. If you're that kind of geek/nerd that likes physics (you don't need to be an expert, just an enthusiast) this book will be great. The feeling is really different between the book and the movie, so if you just watched the movie (like I did before reading) I really recommend you to read the book before rating the story. Review of The Future of the Professions: How Technology Will Transform the Work of Human Experts Unknown — Wed, 01 Jun 2016 00:00:00 +0000 Book: The Future of the Professions: How Technology Will Transform the Work of Human Experts</a> by Richard Susskind. Rating: ⭐️⭐️⭐️. It is a nice idea and the arguments looks valid and make you think about the future. The book is not easy to follow through and I the first 5 chapters are not so interesting. Most part of the book is an introduction to the main subject that is presented on the last chapters. Here are my notes for this book: More people in our world have cellphones than teeth brusher</li> We need to be experts to know to to seek an expert.</li> Driverless car, doctorless patient, lawierless client</li> Pay by value generated instead of hours worked. In the online market it will not make sense.</li> We process more data than we get knowledge from.</li> Mistification of professioes and complicated words being used to create a social closure.</li> If you fold a paper X times you will have light years of size</li> Coisas podem ser transformada em digital mas o objeto não. Industrial goods.</li> Shoulders of giants</li> We have more information than we crn manage with knowledge (number of drugs for a doctor)</li> Network professionals - Remote team. They are not hired full time but by project.</li> Knowledge engineering - expose information withiut content with a human being via online services</li> Communities of experience - People sharing through systems like wikipedia. Less formal.</li> Embedded model - proactive information in a machine</li> Machine generated model - big data and AI develop the knowledge to solve a problem. Helps defining when to ask for help.</li> Professions were created because we cant have sufficient knowledge to deal with all problems we have, so we ask people with pratical experience.</li> A task that is so simple to a robot to do is benief the dignity of the human brain</li> A ideia das profissões é levar conhecimento aos leigos e ajudá lis a resolver os problemas. É um meio, não um fim</li> Machines will kill professions but open space for new tasks</li> </ul> Review of Docker Security: Using Containers Safely in Production Unknown — Mon, 23 May 2016 00:00:00 +0000 Book: Docker Security: Using Containers Safely in Production</a> by Adrian Mouat. Rating: ⭐️⭐️⭐️⭐️. It's a good book for who is using or planning to use Docker in production. There are some very good tips that are not so obvious about Docker. Review de Caixa de Ferramentas DevOps: Um guia para construção, administração e arquitetura de sistemas modernos Unknown — Thu, 12 May 2016 00:00:00 +0000 Book: Caixa de Ferramentas DevOps: Um guia para construção, administração e arquitetura de sistemas modernos</a> by Gleicon Moraes. Rating: ⭐️⭐️⭐️⭐️. Um bom livro para quem não conhece as ferramentas de devops do momento e está procurando alguma coisa que seja bem mão na massa. O autor mostra como usar Ansible, Docker, Vagrant e como fazer deploy usando Digital Ocean e AWS de uma forma automatizada e que pode ser aplicada a multiplas linguagens e/ou ambientes. Review of The Wolf of Wall Street (The Wolf of Wall Street, #1) Unknown — Wed, 11 May 2016 00:00:00 +0000 Book: The Wolf of Wall Street (The Wolf of Wall Street, #1)</a> by Jordan Belfort. Rating: ⭐️⭐️⭐️. Did you watch the movie? Yes: you're done. The book does not add anything relevant IMO. No: Watch the movie. In case you prefer books than movies, you may try this one. It is not a bad book and you will see how a smart guy can be a perfect asshole. The only thing that I absorved from this book is: This kind of life is not for me. I don't want to be rich and use all these expensive artifacts like cars, luxury beds and so on. I really can't see any advantage on it. Review of The 7 Habits of Highly Effective People: Powerful Lessons in Personal Change Unknown — Mon, 02 May 2016 00:00:00 +0000 Book: The 7 Habits of Highly Effective People: Powerful Lessons in Personal Change</a> by Stephen R. Covey. Rating: ⭐️⭐️⭐️⭐️. This is a good book. There are some good examples there and it is worth reading, but if you want to understand the habits in a quick and easy manner just read on the author's website. There are some great insights, at least for me, in this book. The author says that the world works on the "outside-in" but we need to work on the "inside out", taking care of ourselves and doing the best to make things better. We need to focus on things we can change, not on abstract things that depend on someone else or any other entity. Begin with the end in mind, don't let other people shape your way. We see the world as we are and not as it really is, sometimes we need to put ourselves in other people shoes to really understand how is their vision. Review de Ferreiro de Bosque Grande Unknown — Mon, 25 Apr 2016 00:00:00 +0000 Book: Ferreiro de Bosque Grande</a> by J.R.R. Tolkien. Rating: ⭐️⭐️⭐️⭐️. É um livro muito legal para quem é fã de Tolkien. A história é bem pequena, menos da metade de livro. O restante do livro é um pouco de contexto sobre a história e porque ela foi escrita, juntamente com algumas ligações sobre a vida do Tolkien na época. Esse foi o último livro escrito pelo Tolkien antes de sua morte e diz muito sobre o seus pensamentos sobre escrita, sobre o mundo das "fadas" (que não tem nada a ver com o que pensamos dele atualmente) e sobre a vida no geral. A história em si lembra um pouco do "Mestre Gil de Ham" no estilo de escrita. Review of Getting Real: The Smarter, Faster, Easier Way to Build a Web Application Unknown — Mon, 04 Apr 2016 00:00:00 +0000 Book: Getting Real: The Smarter, Faster, Easier Way to Build a Web Application</a> by 37 Signals. Rating: ⭐️⭐️⭐️⭐️. There are almost 10 years from this book release and the ideas are still valid for the software development industry that we have now. Some of them can't be applied to big and established companies, but it shows why small companies can beat them if they know how to organize. "Divide and conquer" and "Do only what is needed" are the core of this book IMO. This book is still inspiring for who that wants to create a new product (or improve the current ones) and it's less then 200 pages. Worth reading. Review of Hackers: Heroes of the Computer Revolution Unknown — Fri, 01 Apr 2016 00:00:00 +0000 Book: Hackers: Heroes of the Computer Revolution</a> by Steven Levy. Rating: ⭐️⭐️⭐️⭐️⭐️. Great book. John Carmack said it was the most inspiring book for him and I can understand why. The word Hackers is not the same these days, but the Hacker Ethics still lives in some of the programmers out there. Those guys that keep hacking (and/or programming) for hours and hours just for the joy of create and modify things still exists. It made me think about the old times when I used to use part of my "sleep time" to work on some C++/SDL code just to understand how could I bring 2D game to life with these tools. This book (and these old hackers) motivated me to bring my hacker lifestyle again. It's time to get back. :) Review of MONEY Master the Game: 7 Simple Steps to Financial Freedom Unknown — Mon, 21 Mar 2016 00:00:00 +0000 Book: MONEY Master the Game: 7 Simple Steps to Financial Freedom</a> by Anthony Robbins. Rating: ⭐️⭐️⭐️⭐️. I have mixed feelings about this one. I got some cool insights about financing and how I can improve my plant of financial freedom, but the book was repetitive most of the time. When I started this book my feeling was: "Man, this may be one of the best books I read". Some time ago I was reading a lot of "soon you'll see" or even repeating what was said before. In the end of the book I read some self-help. The last words were really cool, btw. So... I will still keep it with four stars. It do not deserve three. :) Review de O Pistoleiro (A Torre Negra, #1) Unknown — Tue, 08 Mar 2016 00:00:00 +0000 Book: O Pistoleiro (A Torre Negra, #1)</a> by Stephen King. Rating: ⭐️⭐️⭐️⭐️. Nunca tinha lido Stephen King, esse foi meu primeiro livro dele. O começo do livro é bem confuso e muitas vezes eu tinha que reler para entender em qual contexto as coisas estavam acontecendo. Gostei do clima de suspense que o autor coloca em várias partes e das partes bizarras que foram descritas bem o suficiente para me deixar imerso e pensando. No meio do livro as coisas começam a ficar mais claras e a leitura flui mais livremente, talvez seja pela quantidade de diálogos. O final foi bem diferente do que eu esperava, achei legal e meio filosófico. O interessante que ele deu uns pitacos sobre o que pode ser cada coisa e deixou a curiosidade para muitas perguntas não respondidas. Review de O Cavaleiro dos Sete Reinos (The Tales of Dunk and Egg) Unknown — Thu, 03 Mar 2016 00:00:00 +0000 Book: O Cavaleiro dos Sete Reinos (The Tales of Dunk and Egg #1-3)</a> by George R.R. Martin. Rating: ⭐️⭐️⭐️⭐️. It's a good story for those who follow the whole series of "A song of ice and fire" as it occurs around 100 years before the first book. The only part that is a bit annoying is that the story feels unfinished for me in the end, but the whole experience is good enough. Review de A Jornada do Escritor: Estrutura mítica para escritores Unknown — Thu, 25 Feb 2016 00:00:00 +0000 Book: A Jornada do Escritor: Estrutura mítica para escritores</a> by Christopher Vogler. Rating: ⭐️⭐️⭐️⭐️⭐️. Essential reading for those who wants to write a book. I really like the way that Christopher explores movies like Titanic, Pulp Fiction, and The Lion King. The examples of the Hero's journey based on this movie really helped me to understand the various archetypes and how they interact in each stage of the journey. Just read it for the first time but I'm sure that I'll read it again soon and keep it on my desk for reference. :) Review of A Study in Scarlet (Sherlock Holmes, #1) Unknown — Fri, 19 Feb 2016 00:00:00 +0000 Book: A Study in Scarlet (Sherlock Holmes, #1)</a> by Arthur Conan Doyle. Rating: ⭐️⭐️⭐️⭐️. A good book! I always wanted to read Sherlock Holmes books but never tried it. Thanks to BBC's Sherlock Series I decided to give it a try. The good part is that I could understand a lot of jokes that the TV show made and the differences from the 189x to 201x. :) I really recommend you to read it if you like stories on investigation. By the way, watch the TV shows as well, both are awesome. Review of Masters of Doom: How Two Guys Created an Empire and Transformed Pop Culture Unknown — Wed, 17 Feb 2016 00:00:00 +0000 Book: Masters of Doom: How Two Guys Created an Empire and Transformed Pop Culture</a> by David Kushner. Rating: ⭐️⭐️⭐️⭐️⭐️. I love this book. The two Johns created an empire by using the engineering capabilities of Carmack with the enthusiasm and ideas of Romero. There are some other thoughts to put in this book. The two Johns are doing great and creating amazing games following the startup way of life, relying on junk food and diet coke. Everything was balanced, they had a committed engineer that is addicted to creating new things and pursues really hard challenges. But they also had a good game designer that is eager to test the new advances in technology and create the most awesome game in the world. When the two Johns decided to split, the two sides suffered. And the same situation happens a lot in companies these days. Sometimes we have an awesome engineer that can't spread the awesome tools he is creating. The same situation occurs when we have an average programmer that brings people together and encourages everyone to create and use the tools that are being created but are not so awesome. By creating a team with these complimentary profiles it is possible to generate awesome things as DOOM was at the time it was created. Review de Cartas do Papai Noel por J.R.R Tolkien Unknown — Sat, 13 Feb 2016 00:00:00 +0000 Book: Cartas do Papai Noel</a> by J.R.R. Tolkien. Rating: ⭐️⭐️⭐️⭐️. Eu realmente admiro o J.R.R Tolkien. Esse tipo de livro mostra como ele usava toda a sua imaginação e suas habilidades para fazer coisas para os filhos dele. Para quem é fã das obras do Tolkien vai curtir bastante esse livro. Se você é pai (não é o meu caso) talvez veja uma forma legal de lidar com o seu filho pequeno e fazer brincadeiras durante os anos. Review of The Big Drop: How To Grow Your Wealth During the Coming Collapse Unknown — Wed, 10 Feb 2016 00:00:00 +0000 Book: The Big Drop: How To Grow Your Wealth During the Coming Collapse</a> by James Rickards. Rating: ⭐️⭐️⭐️. TL; DR - A lot of theories about the next economic crash, if you want to know some connections between gold, dollar and other different investments to protect you in case it happens, it may be a good book for you. I'm Brazilian and some part of the economic context is not the same here, but there are some parts make totally sense. In case you like economy, or has some investments and want to understand some relationships, or just want to "be warned" about what may come in the future, this book would be good for you. Review of Freakonomics: A Rogue Economist Explores the Hidden Side of Everything Unknown — Wed, 03 Feb 2016 00:00:00 +0000 Book: Freakonomics: A Rogue Economist Explores the Hidden Side of Everything</a> by Steven D. Levitt. Rating: ⭐️⭐️⭐️⭐️. Nice book with really interesting statistics done in some sets of data. It remembers me about the whole "big data" trend that we have today. In some parts it looks like the comparison of the global warming and the number of pirates (as my "Statistics One" professor and the book author used to say: "correlation does not imply causation"), but the whole idea behind the studies are really interesting. It is all about using creativity to find the "most right" data to understand what happened in the past. Review of Management 3.0: Leading Agile Developers, Developing Agile Leaders Unknown — Thu, 31 Dec 2015 00:00:00 +0000 Book: Management 3.0: Leading Agile Developers, Developing Agile Leaders</a> by Jurgen Appelo. Rating: ⭐️⭐️⭐️⭐️. I read this book in 2015 when the product director of the company I worked for suggested to buy a bunch of copies and do a book club on that book. The director (and many of us, leaders) liked the ideas here, but there were not not attractive to the rest of the directors. Needless to say that reading this didn't change anything in how the company does things. With that said, I love the ideas in this book and I would totally recommend to any manager (along with many other books). I read this book when I was still starting my note-taking approach so I have most of my raw notes written in pt-BR but some of them in English as well. I decided not to change that and post them as they were written in 2015. Here are my raw notes about the book: Desejos do time: colocar um pouco de idealismo, dar autonomia, ajuda-los a fazer o que eles querem fazer, não faça as pessoas se sentirem no fundo da hierarquia.</li> Precisamos de toda a informação para tomar boas decisões, e em sistemas complexos isso se torna cada vez mais complicado, porque toda a informação não cabe no nosso cérebro e pouca informação não resolve.</li> Empowerment, confiar nas decisões de quem você contratou para fazer as coisas. (obs minha: não está confiando? manda embora ou assume o lugar)</li> Fazer a criatividade ficar visível (weekly journal?)</li> Quando os goals da equipe e da empresa divergem é necessário os dois conversarem para chegar num ponto que funcione para os dois, se isso não acontecer vai gerar muito débito motivacional que vai ser difícil de se pagar. 179</li> Sete dimensões dos projetos de software: ferramentas, pessoas, qualidade, tempo, valor, processo</li> Pessoas ao invés de processos do agile manifesto, é muito bom mas só funciona se você tem pessoas boas, senão é um grande fracasso. (The agile blind spot)</li> Quando tem um funcionário com um balance baixo é bom falar com ele para melhorar, se não der manda embora porque ele desmotiva os outros.</li> Times diferentes podem precisar de valores diferentes</li> There is no need for management to make a top-down standardization happen. (Grow standards)</li> Make everything visible. People tend to mimic each other, if you want to spread a technique just show it.</li> Tratar todo mundo como um cliente, sendo interno ou externo. 294</li> Employee morale drops when the best people leave an organization, leading to high pressure on the ones left behind, which further breaks down their morale. (Positive feedback loops)</li> Changing an organization begins with changing management. 306</li> O livro assume que a empresa inteira usa scrum, que é o que realmente faz sentido</li> Open door policy é bizarro. Porque os gerentes/diretores não são só mais um funcionário? Porque não compartilham as coisas com o time, pedem opinião e etc?</li> Criatividade precisa de segurança para expor ideias, começar coisas e falhar, assumindo os riscos. Estamos preparados?</li> Engrenagens da inovação: conhecimento, criatividade, motivação, diversidade e personalidade</li> Declaração da independência: criatividade e inovação</li> É bom o time compartilhar algumas virtudes (respeito?) mas diversidade é importante.</li> Frase de início: quando um ator quer discutir o seu personagem comigo eu digo para ele olhar o script, se ele me pergunta qual é a sua motivação eu respondo: seu salário.</li> Em software, ao invés de energia e força, o importante é comunicação, informação e propósito</li> Complexo é algo que não é previsível (AI, multiplayes games) e complicado é algo que precisa de um expert para entender.</li> </ul> Experiences of almost two years using Colemak Unknown — Thu, 08 Oct 2015 00:00:00 +0000 TL;DR: I like Colemak, and it is a very good layout. I found some equivalent pros and cons, so I can't recommend it to anyone without a little bit of philosophy. :) For those who don't know Colemak</a>, it is a keyboard layout created to make the most used keys stay in the home row as well as make you swipe between your right and left hand. There is a keyboard layouts heatmap</a> for you to understand the benefits of using a keyboard layout that was designed to help you to be comfortable and fast when typing instead of one that helping the operator to not jam the typewriter</a>. I tried some code (python), English and Portuguese texts and it looks almost the same on the heatmap. I'm using Colemak since Dec, 25 of 2013 and here come the pros and cons that I found: The first con is that I don't know how to type fast on Qwerty anymore, now I'm typing as I never saw a Qwerty layout before. The problem is that everyone uses this crappy layout and sometimes you need to use it to write and it makes you look like a grandpa. The good part is that I almost don't need to use Qwerty, all devices that belong to me I've changed to Colemak (computers, cellphones and so on), so I just need to use Qwerty when I'm typing on other peoples devices. A pro is that my typing speed grew from an average of 75 WPM to almost 100 WPM. I need to consider that I also bought a Kinesis Advantage Pro; Without this keyboard, I'm not that fast. Just tried 10fastfingers now and got 92 WPM</a> using my laptop's keyboard. Another pro is that I really feel comfortable using Colemak, you the same way as being an experienced Vim user, looks like you don't need to type so much. :) Now, talking about Vim... I'm an experienced Vim user, but Vim is totally coupled with the Qwerty layout. I tried to remap some keys (like hjkl for example) in order to keep using the home row to navigate but it was not very good. Today I'm just using the plain Colemak layout on Vim and it is not so good as it was on Qwerty. For this reason, I decided to try a new editor and I'm using Emacs now. :) It took me at least a month to get back to my old typing speed, I was training every day on 10fastfinges to get used to the layout. In the beginning, you may feed some headaches because of the mind remapping. It's not so easy to change something that you thought was the only way of getting things done. It was a great challenge for me and it just seems right, I don't wanna use a keyboard layout that was made to avoid jams on a typewriter, Jesus, we're in 2015 and there are no typewriters anymore. Hope this post helps a lot of Colemak newcomers and the only thing I could say about my journey is that I would do it again if I could. :) As escolhas do desenvolvedor Unknown — Mon, 31 Aug 2015 00:00:00 +0000 Esse ano fui chamado para palestrar em todas as edições do Encontro Locaweb que acontecem por várias cidades do Brasil! Palestrei em 6 cidades de estados diferentes, e aconteceram na seguinte ordem: Belo Horizonte</a></li> Curitiba</a></li> Recife</a></li> Porto Alegre</a></li> Rio de Janeiro</a></li> São Paulo</a></li> </ol> Adicionei os links para as fotos dos eventos na listagem acima. :) Minha palestra se chama "As escolhas do desenvolvedor" e fala sobre as escolhas que fazemos durante nossa carreira de desenvolvedor, escolhas com linguagens, configurações de servidores, deploy, equipe, testes e etc. A ideia dessa palestra é mostrar as opções que temos para cada uma dessas etapas. Esses são os slides da palestra: </iframe> Demorei para publicar esse post porque o encontro Locaweb de São Paulo foi gravado e eu estava esperando liberarem os vídeos para eu poder publicar junto com o post. Para assistir é só se increver no grupo do encontro Locaweb na eventials</a> e assistir nesse link</a>. Obrigado a todos que prestigiaram o evento e espero ter contribuído com alguma coisa legal com a palestra. OSCON 2015 Unknown — Mon, 27 Jul 2015 00:00:00 +0000 TL;DR I've been at OSCON this year (thanks to Locaweb</a>) and this post will summarize my impressions about the conference. I spoke at Locaweb Tech-Talks about it and you can find my slides here</a> (in portuguese). OSCON (Open Source Conference)</a> is one of the most important open source conferences of our time and happened in Portland this year as usual. Portland is a great city, the one I liked the most until now, it doesn't have high car traffic, MAX (the train) took us for most of the places we wanted to know, nice people all over the place, great convention center and a lot of other benefits. July, 20</h3> The conference started at 9:00 am of July 20, 2015 with the first day of tutorials. In the first day I followed the Kubernetes tutorial and it was cool. I had the chance to talk with Google guys about it and try Google Computing Engine, which was very nice. July, 21</h3> The second day was filled with more tutorials and I chose RUST and Cassandra. RUST</h4> Was a good tutorial with a lot of exercises and good tips of the language. I really liked it and I'll probably give Rust</a> a try on the next months. Cassandra</h4> I was expecting a different thing from this one. It was based on how to use cassandra</a>, create tables and so on and I was expecting tips on how to create and scale it and maybe a little bit about the caveats we may found on the way. But it wasn't bad at all, I've learned a little bit on how to use it and as a gift I tried a little bit of spark as well. At the end of this day the Expo hall opened for everyone, cool things there (including some T-shirts... T-shirts everywhere). July, 22</h3> Let the conference begin! :) It started with the keynotes at 9:00 and I would like to highlight one of them. All keynotes are avaiable on youtube</a> btw. :) Facebook open source at scale (Keynote)</h4> I like to understand the open source culture behind these big companies. It is really interesting to know that there are only 2 people to handle all the facebook open source process shocked me a litte bit. They have a great open source review and publishing process and all the softwares they release are running in their production environment. So, why do they do open source software? Because it's good for the company, helps them to make better software and bring smart people to work with them. And then the multiple sessions started, a lot of great subjects in the agenda and you have to choose one (!!!). Roller Coaster Tycoon with genetic algorithms and Go</h4> The speaker Kevin Burke</a> spoke about his hobbie of playing with roller coaster tycoon</a> game maps with Go and Genetic Algorithms in order to create de best roller coaster ever! It is not there already but the presention was really cool to follow. You type "google.com" into your browser bar and press enter: What happens next?"</h4> The speaker for this talk is Graeme Mathieson</a>. I was planning to spoke about it before de last edition of DevInSampa</a> (2012? Btw, it could happen again...) but didn't had the guts to make it yet and there it is, someone made it before me. The pace of the presentation was not good but the content was cool (it was his first presentation). At least it made me think more about this topic and maybe I'll try to speak about it soon. After the lunch I tried to attend to Evolution of information security threats presentation but the room was full, so decided to go to Matrix</a> guys presentation. Fixing the fragmentation problem for real-time communications</h4> Matrix's is really interesting, the main idea is to make a protocol for messages, just like the email protocols do for our email, we may use our client and store our own email but it is not possible with today's messaging like hangouts, whatsapp, telegram, skype and so on. They had a live demo piloting a quadricopter via chat, it was really cool. High adventures in sniffing my own metadata</h4> The speaker is Josh Deprez</a> from Google Australia. He described his work using a Go program (home made) to analize his own internet traffic and which information he got on it. The presentation itself was cool to follow but the discoveries wasn't so much interesting. :P Building the $9 computer, or how I learned to stop worrying and love embedded Linux</h4> This is the C.H.I.P project</a> owner Dave Rauchwerk speaking about the story behind the project. This guy is hilarious and a real hacker, he made a gif camera just for the lulz and tried a product with it! Unfortunately it was too expensive, to be viable for selling, so he decided to create C.H.I.P to make the camera cheaper and C.H.I.P became the product by itself. Continuous delivery and large microservice architectures: Reflections on Ioncannon</h4> This last one was really interesting Kevin Scaldeferri from New Relic</a> spoke about how they grown from a big and monolythic Rails application to 250 microservices. In short, it was a mess in the beginning, a lot of techlologies and deploy tools until they organized and found a standard for the language and deploy tools, it is really better now, but the old Rails app is still there. July, 23</h3> A new day with an typical American breakfast at Denny's and starting with keynotes at 9:00 AM again. Making architecture matter (Keynote)</h4> Martin Fowler</a> spoke about architecture in general, there was some good quotes. One of the arguments that really make sense is that the today's "Architect" is that guy that don't write code (!?). How can a professional that doesn't write code talk about how to write code? Another good point was about the user perspective about architecture it can't see it anywhere but still need to pay for it! We need to argue using economic principles in order to be able to create a good architecture for our softwares because economics always win. We have a lot of examples of products that were the market leader for their segment and it could not evolve anymore to the point that it was swallowed by another competitor. This is a sign of bad architecture. You code like a sysadm</h4> hm... This talk was not so good but it left a message for everyone: "Bad code is still better than no code at all" And obviously: Good code is better than bad code. So, instead of not doing something because you think your code is not good enough, do it and improve as soon as possible. When Performance Counts: C++ in the 21st Century</h4> The speaker threw some good arguments that haven't came to my mind until this day: "Why is C++ getting more attention these days?", we have C++11 being created and more people talking about it. In his words, the world was not in need for performance anymore, we had big computers and most of time the other languages (java, in his examples) are doing a good job to create what is needed without the need to manage memory by hand. But today we have some other hardwares that need this performance back, like tablets, mobile devices, cloud applications that pays based on cpu time and so on. Good catch man! :) Creating an open source office: Lessons from Twitter</h4> I made a bad choice based on the presentation title and changed rooms as fast as I could to follow this one. Some notes on the presentation: Ensure projects have owners or give it to the community: this is the twitter example of Twitter bootstrap</a></li> Always say Thank you for your project collaborators</li> Lessons from mesos</a> Apple uses mesos for Siri</li> Open source foundations force good pactices on you (incubated aurora)</li> </ul> </li> Lessons for twencache</a> Keep track with the upstream if you fork something</li> Share your code with some peers to gauge interest</li> open source project with collaborators is better</li> </ul> </li> </ul> A good lesson that I got from this presentation is that community doesn't come for free. Companies like Twitter have their own community managers, conference speakers, conference organizers, documentation writers and their developers to make everyone engaged with the project. Throw something on github and expect collaboration is not the best idea for OSS. Your employess may become open source celebrities sometimes, and if they became popular they may leave the company. It is not so good for the company but the same popular projects may attact new talents as well. :) Troll's are everywhere and youy will always hear that your project is stupid and useless. The best way to deal with it is to take it as a compliment because people care enough to say it. Mesos the OS for your datacenter</h4> David Greenberg from Two sigma</a> spoke about how they built their own mesos</a> framework. Mesos has a high level API to do things and you don't need to care about the resources. It provide an algorith called DRF</a> for a fair allocation of resources. There are several built frameworks for mesos like Marathon, Aurora, Jenkins and some more. It's easy to build your own framework (netflix, twitter, apple and two sigma have it). A good reason to build your own is to deal with some exotic workload, this default frameworks are built for small tasks. For me, mesos is the future and I'll definitely be looking for it. July, 24</h3> This was the last day of the conference and it started with 3 keynotes. After the keynotes there was two sessions more and the conference ending at the main ballroom. Hacking Conway's Lay (Keynote)</h4> organizations which design systems ... are constrained to produce designs which are copies of the communication structures of these organizations —M. Conway[2] </blockquote> When rebuilding a system it's really important to think about your team because it will be part of its architecture like conway's law says. So when a decision is made to build a new system without changing the way people work you will face the same problems the other system had but with a different code. Doesn't matter if you're using microservices but your team is still monolithic. To solve technical problems, you often have to go outside the technical domain. Raffi Krikorian </blockquote> Good points that ended the presentation: It's not all about the code!</li> Small teams can do big things.</li> Full stack teams keeps your architecture flexible.</li> Don't fight Conway's Law, work with it.</li> </ul> A lot of good lessons learnt from this one. :) Build a botnet?</h4> The speaker (Bryan Smith</a>) did a great (and funny :P) presentation around the topic. And some things are really scary when speaking about botnets. The most scary thing for me was its price, you can use a botnet for an hour spending only $5... it is really low and probably will get a service out of business for that time. There are some softwares avalable if you want to build your own botnet these days (accorting to Bryan, if you want to build a botnet you're probably a scumbag... LOL), here are some of them: citadel</li> kreios C2</li> Andromeda V2.6 - leaked</li> Kaiten IRC bot</li> SDBot - GPL</li> DSNX Bots</li> Q8 Bots</li> </ul> I'll not post links here but you can google them if you really want it. :P The most funny part of the presentation was its end when the speaker laptop got rebooted when trying to bring the botnet up. LOL Freedom and responsibility @Netflix: Centralized team in a decentralized world</h4> One of the best presentations of the conference. Mike McGarr</a> spoke about his team (tools team) role at Netflix</a> and the hacker culture there. One of the team roles is to increase the rate of innovation and reduce the impact of change by providing good tools for the other teams. Their clients are the other teams engineers, it's not a simple internal system it's a product! Netflix has a great culture</a> and each team as a subset of this culture. Netflix has a lot of good tools but the engineers may choose to not use it and build their own in case it doesn't fix their problems. For this reason there are 4 deploy tools running on Netflix actually. They have no Ops team, you build it, you support it! And in order to remove part of the constant interruptions, the team uses a "responder rotation" when each time (day, week, month?) a new engineer will be in charge of solving problems and helping the other teams. They (like many of us) don't like ticket systems, but they use it anyway (like many of us?). For this case the tip is: Make creating a ticket easy, minimize fraction by making it as easy and fast as possible. Hackatons are made between the team in order to keep the innovation process flowing and making space for innovation. Another good thing to think about is to always hire beyond your needs, it makes more space for innovation (not all people working on day to day tasks) and it will be really helpful when the project is on fire and the team needs more intensity on it. Communication is really important for the teams and they do not set a limitation for important communications like framework versions and DC migrations. For this task they use hipchat, email, banners and everything that may call the engineers' attention. Situation normal, everything must change</h4> This was the last keynote and maybe the best one, and I highly recommend you to watch it</a>. Simon Wardley used the fact that OSCON is moving to speak about situation awareness and what could happen when you're not prepared for a new thing. His arguments are that we're using the wrong maps to try to understand our problems. In business we use SWOT</a> for example, which is really bad to understand to understand the whole picture, it was really funny to see his comparisons with the battle of the 300</a> using a SWAT map instead of land map. LOL The speaker shows some maps he uses for his business, and it looks really better than just a SWOT. :) Again, I really recommend you watch this talk</a>. I liked it. :) Conclusion</h3> The best conference I ever attended. Everything was great: hotel, Portland Conference Center, the city in general, the food, the conference content and so on. It definitely worth the 14 hours plane travel to be there. I would live in a city like Portland, it is one of the best cities I ever visited. I'm sad to know that the next OSCON will happen in Austin instead of Portland. :( New layout of PotHix blog Unknown — Mon, 25 May 2015 00:00:00 +0000 Welcome to the new blog layout of PotHix.com! :) I decided that the time has came to change not just the layout but the blog engine as well. I'm now using middleman instead of wordpress. Just to be clear, I don't think wordpress is not good at all, but I want to publish static files instead of keeping the wordpress "infrastructure". I've divided into 3 feeds: Only english posts: http://feeds.feedburner.com/EnglishPotHix</a></li> All posts: http://feeds.feedburner.com/PotHix</a></li> Posts related to programming or technology in genenal: http://feeds.feedburner.com/PotHixTech</a></li> </ul> So, that's it! Hope you enjoy the new layout (now responsive!) and get in touch! :) Ruby, Python e native threads Unknown — Fri, 14 Feb 2014 00:00:00 +0000 Pode ser que eu seja meio burro (heheh) mas eu ainda achava que o Ruby e o Python usavam Green Threads, mas depois de conversar com uma galera me disseram que eram threads nativas. Pesquisando na internet eu vi que eram mesmo, mas decidi rodar um strace para ver elas rolando e postar sobre isso. Fiz dois scripts simples: Python import threading import time for i in range(5): t = threading.Thread(target=time.sleep, args=(1,)) t.start()</code></pre> Ruby require 'thread' 5.times do Thread.new {sleep 10} end sleep 1</code></pre> Rodando o script python com o comando strace -f -e clone,fork python thread.py</code> retorna pouca coisa: clone(Process 13920 attached child_stack=0x7f8570b67ff0,

Durante a conversa o @nuxlli perguntou sobre como o Guru-SP começou e nesse momento eu comecei a relembrar daquela velha tarde em 2008. Mas peraí... 2008!! O Guru-SP está próximo de fazer 5 anos de vida! :) Em pensar que tudo começou após um post do @agaelebe na Rails-br</a> falando sobre criar grupos locais para conversar mais sobre Ruby e fazer encontros com mais frequência, o que gerou interesse de várias pessoas de São Paulo, que decidiram levar esse "projeto" pra frente. Logo em seguida o @mfcastellani</a> já iniciou as primeiras discussões</a> no grupo do Guru-SP</a> e aproveitamos para agendar o primeiro encontro</a> numa churrascaria qualquer no ABC que era mais próximo da casa do @mfcastellani</a>, pois como ele nos contou depois: "Se não aparecer ninguém só comeria uma carne e voltaria para casa". hahaha E algumas pessoas compareceram, eramos 3 pessoas conversando sobre o que poderia ser o Guru-SP no futuro. Não conhecia o @mfcastellani</a> nem o @agaelebe</a>, mas ficamos boa parte da tarde conversando sobre desenvolvimento no geral e planejando o que seria legal fazer no grupo (camisetas, eventos maiores, encontros mensais, e etc). Logo conseguimos as camisetas do Guru-SP! Depois de cotar alguns fornecedores e fazer um desenho legal para representar o grupo rachamos as despesas e mandamos fazer camisetas para quem estivesse interessado. Com a entrega das camisetas consegui conhecer muita gente que não conhecia pessoalmente. Aproveitamos que alguns de nós estariam na Campus Party e fizemos o segundo encontro por lá! Como sempre tinha uma quantidade enorme de pessoas: Eu, o @mfcastellani</a> e o @akitaonrails</a>. O @shadowmaru</a> apareceu também, mas só me encontrou para pegar a camiseta. Nesse meio tempo já estávamos planejando aquele "encontro maior" que conversamos no primeiro encontro, e poucos meses depois saiu o Ruby + Rails no mundo real</a> com o auxílio da Tempo Real eventos. Apesar do quarto ter uma quantidade pequena de pessoas (apenas o @rafaelrosafu</a> e o @agaelebe</a>), o quinto encontro me surpreendeu bastante. Ao chegar na Voice Technology (onde o @andre_pantaliao</a> trabalhava na época e conseguiu o espaço para o encontro) eu encontrei uma sala com mais de 20 pessoas aguardando as palestras! O encontro foi bem proveitoso e mais do que nunca percebíamos o Guru-SP crescendo. Eu considero que depois desse encontro o Guru-SP começou a andar sozinho, conseguimos empresas parceiras para nos ajudar, o grupo cresceu bastante, sempre tinhamos boas talks nos encontros e etc. Hoje o Guru-SP tem mais de 1100 inscritos na lista, e já tivemos encontros comuns com mais de 100 pessoas, isso sem contar os eventos que organizamos e que tiveram mais de 200 pessoas. Temos empresas que sempre nos ajudam, seja com espaço ou coffee break. Vale agradecer a Caelum que por muito tempo nos forneceu o auditório mensalmente, e ainda hoje sempre nor provê espaço quando precisamos. Não vou tentar citar todas as empresas que ajudam porque sempre vou deixar uma de fora, mas dá para ver cada um dos patrocínios na página de encontros do Guru-SP</a>. Atualmente o Guru-SP não é somente focado em Ruby, mas aproveitamos muitos dos conhecimentos diversos de todos os participantes para trazer bom conteúdo em várias partes da área de desenvolvimento, o que faz com que cada vez mais tenhamos conteúdo legal e interação entre a galera. Parabéns aos Guru-SP pelos 5 anos de vida e para todo mundo que ajudou (e/ou ainda ajuda) na organização para fazer um dos grupos de Ruby mais ativos do Brasil, e mais do que isso um lugar legal para troca de conhecimentos. Vendo Dragstar 2008 Unknown — Mon, 29 Jul 2013 00:00:00 +0000 Chegou a hora de pendurar o colete por um tempo, obviamente estarei de volta num futuro não tão distante, mas pelo menos por enquanto vou ficar um tempo sem motos.

Estou com ela desde 2008 e só me deu alegrias. Algumas informações sobre ela: Único dono</li> Toda a parafernalha que veio com ela quando eu comprei eu ainda tenho</li> IPVA pago</li> Pneu traseiro praticamente novo, não rodou nem 100km</li> Bateria nova, 1 mês de uso</li> Motor, protetor de corrente e paralamas frontal são preto fosco.</li> </ul> Acessórios (fora todos os itens originais que vão junto!) Guidão seca de 45cm que mandei fazer especialmente para ela</li> Sissy bar</li> Retrovisor pequeno</li> Escape aberto feito especialmente para ela</li> </ul> Quem estiver interessado é só entrar em contato por email, ou aqui nos comentários mesmo. Vendendo minhas coisas Unknown — Mon, 29 Jul 2013 00:00:00 +0000 Esse ano aconteceram algumas coisas zuadas para mim e resolvi capitalizar o dinheiro das coisas que eu tenho e começar denovo no ano que vem. Procurei preços justos para tudo que estou vendendo (os links das minhas pesquisas estão nas descrições dos produtos), mas caso alguém ache que alguma das coisas está com um preço não-justo e estiver interessado é só entrar em contato que negociamos. Estou aproveitando para testar a plataforma do loja integrada, mas os pagamentos eu prefiro que sejam por depósito mesmo, e se possível marcamos a entrega pessoalmente. Dá para acessar a loja pelo link http://loja.pothix.com</a></a> (redireciona para a lojaintegrada</a>). Espero conseguir vender essas paradas o quanto antes. :) Quem puder me ajudar a divulgar eu agradeço muito. Game Network Programming Unknown — Mon, 15 Jul 2013 00:00:00 +0000 English Abstract: This post was about my presentation with Diego Souza (vulgo Marciano) about Game network programming. I was studying and reading Quake source just for fun and decided to learn more about game networking in general, so I decided to prepare this presentation to show other people what I’ve learned. You can see the full video (portuguese only, sorry) and the slides below. Portuguese: Eu e o Diego Souza (vulgo Marciano) fizemos uma palestra sobre Game network programming tanto na Locaweb como no Guru-SP. A palestra que fizemos no Guru-SP foi gravada pelo Agaelebe e está disponível no Youtube</a>. Como eu estava na vibe de jogos desde o começo do ano passado, eu estava lendo os posts sobre o código do Quake. Quem me conhece sabe que eu trabalho na equipe de IaaS da Locaweb e lá nós lidamos com bastante coisa de redes e eu curto o assunto. Conversando com o Diego sobre os algoritmos de redes utilizados no Quake nós decidimos juntar as pesquisas dele sobre os protocolos TCP e UDP com o que eu li sobre a implementação dos algoritmos nos jogos para poder fazer uma palestra legal de game network programming, e assim saiu essa palestra. Lá nós apresentamos os algoritmos de alguns jogos como o Quake, Age of Empires e outros não tão conhecidos, mostrando as soluções legais que eles chegaram e quais foram os maiores desafios que eles encontraram para resolver os problemas de latencia e necessidade de velocidade. O Diego focou mais na parte de otimização dos algoritmos e flags que podem ser alteradas para melhorar o comportamento da rede. Essa foi uma palestra muito legal de fazer e aprendi bastante no processo também! Se tiverem dúvidas postem aí nos comentários. :) Plaev, HTML5 e Skeleton-jigsaw Unknown — Tue, 04 Dec 2012 00:00:00 +0000 Depois de muito tempo desenvolvendo finalmente terminamos o Skeleton-Jigsaw em outubro! Demorei para postar sobre isso aqui no blog por falta de tempo, mas aqui está! Eu e o Rafael Masoni trabalhamos nesse jogo durante quase 1 ano (começamos a falar dele no comecinho de janeiro) investindo nosso tempo livre para fazer todas as partes do jogo (audio, programação, arte, game design, level design e etc). Vou descrever um pouco do que fizemos e como organizamos, mas vai ser apenas um resumo do que falamos na nossa palestra no Guru-SP: </iframe> </iframe> Obrigado pelo vídeo Agaelebe! Começamos a trabalhar em janeiro do ano passado no que seria um protótipo da impact e aos poucos o jogo foi tomando forma e estavamos investindo cada vez mais esforço nele. A cada semana fazíamos uma Skype call para discutir no que trabalharíamos durante a semana e fazíamos o possível para entregar o que conversamos até a próxima call. Foi bem legal trabalhar em todos os pontos do jogo, opinando em arte, trabalhando em trilha sonora, programando, discutindo level design, escrevendo uma prévia de história, otimizando assets, testando em vários navegadores, fazendo game design e tudo mais. Todo esse trabalho trouxe muitas experiências legais de como é entregar um jogo funcional e completo para o seu escopo, e estou bem orgulhoso de conseguir entregar o jogo demo finalizado, e não deixar mais um trabalho incompleto perdido por aí. Ainda não sabemos quais os planos para a Plæv, mas agora ela já tem seu primeiro jogo demo para não ficar com o portfolio em branco. :) Não quis descrever muito aqui no post para não ficar somente repetindo conteúdo do vídeo, mas se tiverem dúvidas coloquem nos comentários. Saudades do Poker Unknown — Wed, 31 Oct 2012 00:00:00 +0000 Apesar de eu não ser bom o suficiente eu curto bastante jogar poker, mas as poucas vezes que me juntei com os amigos pessoalmente para jogar foi na época da faculdade, que marcavamos as "poker nights" e jogavamos apostando pequenas quantias. Depois de sair da faculdade eu sempre penso em tentar juntar aquele pessoal novamente, ou até mesmo juntar outras pessoas para poder jogar, mas eu acho difícil conseguir contato com o aquele pessoal novamente e a galera que eu tenho contato hoje geralmente não sabem jogar e tampouco se importam em aprender, ainda mais quando sabem que o jogo só tem graça quando está valendo dinheiro. Há pouco tempo atrás eu estava assistindo um jogo de poker pela internet e resolvi procurar mais informações, sobre quando aconteciam os jogos (transmitidos pela internet) e até cheguei a ver alguns documentários e reportagens de pessoas que vivem de poker e passam o dia jogando pela internet, o que lhes traz uma quantia considerável por mês. Resolvi começar a jogar pela internet novamente nas horas vagas e escolhi o partypoker para brincar. Ao entrar no site descobri que o instalador era para Windows, mas como eu já estava acostumado a ver sites de poker com instalador para windows eu decidi usar a interface web deles que funciona com um applet java e rolou tranquilo. Update: hoje em dia eu prefiro muito mais jogar na ReplayPoker</a>, porque acho o site deles bem melhor e tive a chance de conversar com o criador do site e a equipe de desenvolvimento alguns anos atrás. Jogar poker pela internet é bem divertido, e também necessário para quem quer levar o jogo a sério, mas eu ainda sinto falta de juntar os amigos pessoalmente e passar uma boa parte do tempo tentando adivinhar a poker face da galera para não ver meu dinheiro se perdendo. :P Se alguém aí costuma se juntar para jogar, não esqueçam de me incluir! :) A lifestyle Unknown — Mon, 10 Sep 2012 00:00:00 +0000 Just a transcript from here</a>, but it reflects my way of life at this stage of my life: We believe in going our own way,no matter which way the rest of the world is going. We believe in bucking the system that’s built to smash individuals as bugs on a windshield. Some of us believe in the man upstairs.All of us believe in sticking in to the man down here. We believe in the sky and we don’t believe in the sunroof. We believe in freedom. We believe in dust,tumbleweeds,buffalo,mountain ranges and riding off into the sunset. We believe in saddle bags and we believe that cowboys had it right. We believe in refusing to knuckle under to anyone. We believe in wearing black,because it doesn’t show any dirt or weakness. We believe the world is going soft and we’re not going along with it. We believe in motorcycle rallies that last a week. We believe in road side attractions,gas station,hot dogs and finding what’s over the next. We believe in rumbling engines,pistons the size of garbage cans,fuel tanks designed in 1936, freight-train size headlights,chrome and custom paint. We believe in flames and skulls. We believe life is what you make it,and we make it one hell of a ride. We believe the machine you sit on can tell the world exactly where you stand. We don’t care what everyone else believes.</code></pre> ;) Javascript and Gamedev discussion Unknown — Sun, 02 Sep 2012 00:00:00 +0000 I read the blog post</a> from Impact engine</a> creator Dominic</a> where he shows an email he sent to John Carmack</a> about his opinions on Javascript expressed on his keynote</a>. Dominic is trying to show that Javascript is not a good language to develop the next AAA game but it is awesome to make simple games and have it easily available to the world. We have a lot of negative comments on the post (I really don't know why) but some good ones too. One of the good comments was written by John Carmack himself! He was just explaining his point of view about Javascript and game development, and said what we already know and is obvious (right?) that javascript is not so fast to perform some kind of tasks. Some people are dreaming that Javascript is so fast as C in some cases but we know that it is not true for a whole game and the native version will always run faster. But you should say that the web (and the computers at all) are evolving each day, so the javascript performance, but the native version is evolving as well and javascript will always be some steps back. John's comment is really interesting because he knows that javascript has its benefits but he also knows that some of the real problems they are solving at Id Software</a> will not be solved efficiently using Javascript (and a browser) as the platform. The conclusion for the discussion is what I was expecting: "Choose the right tool for the right job" Are you doing a little 2D game? Try javascript, and define the platforms for it to run. But if your game really needs performance because you need to have the most impressive graphics, you need to go native. Obviously you should choose a lot of different languages / platforms as well, you just need to decide which one is better for your business. Use the right tool. That's it, no silver bullet. :) Review de Ruby on Rails: coloque sua aplicação web nos trilhos Unknown — Wed, 08 Aug 2012 00:00:00 +0000 Book: Ruby on Rails: coloque sua aplicação web nos trilhos</a> by Vinícius Baggio Fuentes. Rating: ⭐️⭐️⭐️⭐️⭐️. Esse livro é muito legal para quem não conhece Rails e quer colocar a mão na massa criando uma aplicação do zero. Com ele você consegue explorar uma boa parte do que é necessário para criar uma aplicação comum usando o framework. Kernel compiling Unknown — Mon, 23 Jul 2012 00:00:00 +0000 Since I bought an Acer notebook to use Linux again (I sold my mac, I have a post about it but in portuguese) I started to compile my own kernel. The reasons for the decision: I have a hardware that works better with the newer kernels. I really want to understand the linux kernel better. As Judas Priest sings on Painkiller song: “I’m living on the eeeeeedge”. LOL How to proceed</h3> There are some steps to follow when compiling a new kernel for your Linux box: Clone the kernel repository with git, I made it using the Github url: git clone git://github.com/torvalds/linux.git</code></pre> Copy your .config file to the linux folder. If your distro have the "Enable config.gz" flag enabled (most distros have it) you can use the generated config as a base for your new compiled version: zcat /proc/config.gz > linux/.config</code></pre> Now that you have a functional config file (it was running on the stock kernel right? ), just cd do the kernel folder and run make: cd linux make</code></pre> This process take about 40 minutes to finish on my i7, with 4GB of RAM and SSD, running with -j4, to use all the 4 cores. Obviously the time to finish will depend on what it will need to compile (defined on the .config file) and the processing power of your machine. You can improve this compiling time but I’ll talk more about it later. You can use the compiling time to prepare the mkinitcpio file for the installation. On my archlinux box I have created a file named git.preset on /etc/mkinitcpio.d/ directory with the following content: ALL_config="/etc/mkinitcpio.conf" ALL_kver="/boot/vmlinuz-git" PRESETS=('default') default_image="/boot/initramfs-git.img"</code></pre> After that you’ll need to change your bootloader conf a bit. I’m using grub (not grub2 yet) which makes the setup really easy! Just change your /boot/grub/menu.lst and add something like this: title Git Kernel root (hd0,0) kernel /vmlinuz-git root=/dev/sda2 ro quiet acpi_backlight=vendor init=/bin/systemd initrd /initramfs-git.img</code></pre> PS: I’m using systemd to init and I need to define the acpi_backlight to make my hardware to work properly, but probably you’ll not need these parameters. If you’re using grub, you may find useful to copy the other configuration of the same file and change what needs to me changed (title and initrd). When the compilation ends and your mkinitcpio file is ready you can continue the process by generating the modules for your kernel: sudo make modules_install</code></pre> This command will create a folder with the compiled modules on /lib/modules. After that, just copy the generated image file to the boot directory: sudo cp arch/x86_64/boot/bzImage /boot/vmlinuz-git</code></pre> And create the initial randisk environment for your preset using mkinitcpio: sudo mkinitcpio -p git</code></pre> DONE! Your kernel is compiled and ready to boot! Just restart you computer and choose the new item on the boot menu! .config tunning</h3> So, your new kernel is running perfectly (I hope so…It’s a release candidate, we never know what may happen :P), but you’ll want to go deeply into the kernel options and improve the compiling time and the disk space for the kernel, so lets tune the .config file to be specific to our hardware! WARNING: It will take a lot of time to get a good configuration and you’ll not receive so much benefit from it, but it will be fun. I promise. So, let’s get started! Go to the linux kernel directory and run: make menuconfig</code></pre> The fun part starts here because you’ll be seeing an awesome curses screen with a lot of menus and submenus about a lot of things that you never heard about, but no despair! Some things you already know, like your processor for example! If you have an Intel processor is safe to remove all the AMD related configurations from the .config file and probably add some intel ones as built in (and vice versa). Some things you need to have in mind when starting to buil your own kernel configuration is that you really need to know what hardware you’re running on your machine. This is really interesting because we don’t care so much about some pieces of hardware nowadays, and you’ll need to care about it if you want to build your own configuration because you can’t remove these modules. A good way to start is boot with the stock configuration, run lsmod and backup this into a file. These modules should not be removed because they are making your machine to work as it is working now, but some of them should be marked as builtin into the kernel. I saw some recommendations to not include the WIFI driver as builtin to avoid some pre-load problems, so I’m keeping my WIFI driver as a module. Some cool (but not so useful) parts can be found on “General Setup”: Default hostname – This configuration will be specific, so name your machine! Local version – Append an string to the kernel release I can’t help you so much on this journey because each hardware has its own dependencies and corner cases, so you will need to compile and see how it’s going to fit your needs. Some tips</h3> If you’re planning to customize your configuration file I really recommend to use a versioning control (like git) to keep tracking of your file because you’ll need to revert some changes sometimes (believe me) and git will help you to make this process less painful. Conclusion</h3> We are weird people (me for writting this and you to be interesting in doing the same thing) but this process will help you to understand some interesting things about your operating system and feel that there is no magic happening there, this is just code that you can change if you want. I was planning to end this article with “there is no advantage on making this at all” but after remembering all the process I think that I learned a lot, so it is worth it. Menos mac e mais Linux Unknown — Thu, 19 Jul 2012 00:00:00 +0000 TL; DR Usei mac por mais de 6 meses e decidi voltar ao Linux. Na minha opinião mac não é ruim, mas Linux é melhor. A idéia desse post não é fazer um flame war, muito menos justificar porque eu voltei para o Linux (afinal, eu não devo nada pra ninguém), e sim falar um pouco do que eu vi de vantagens e desvantagens no Mac e porque eu resolvi voltar a usar Linux. Bem, como muitos sabem eu comprei um Mac no meio do ano passado, era um Macbook pro de 13 polegadas, i7, 4GB de RAM e etc. Como eu imaginava, era uma maquina boa e estável para trabalhar, fazer minhas pesquisas e levar na mochila (era muito mais leve e compacto que meu antigo Toshiba Satellite). Antes de usar Mac eu estava usando o Toshiba Satellite que eu mencionei acima usando Ubuntu como sistema operacional, e tudo estava indo bem sem contar o peso que era levar o computador para a faculdade sempre. Enfim, um colega foi para um evento fora do país e eu pedi para que comprasse um Macbook pro para mim, e assim foi feito, estava com um Mac. Refiz tudo que tinha do Linux para utilizar no estilo Mac, ou seja: Formatei todo o meu HD para usar o formato do Mac, comecei a utilizar time machine, alterei uma boa parte dos meus config files para aceitar Mac também e etc. E lá começa meu uso do Mac, comecei a instalar as ferramentas que eu estava utilizando na época. Primeiro começando com as ferramentas de desenvolvimento, peguei um Xcode com um colega para não precisar baixar e a única coisa que ele fez foi bugar e não deixar nem instalar nem desinstalar (sim, procurei na internet tinham algumas soluções que supostamente resolviam mas não resolveram).... Enfim, foi a primeira coisa que eu instalalei, então foi só instalar o sistema denovo e boa! Baixei o Xcode (mais de 1GB!!!!1!!!um!!), para poder compilar tudo que eu precisava e tudo estava indo bem, só não parecia muito natural algumas coisas para quem está acostumado a usar Linux, mas tava indo bem. Nessa época eu estava terminando o meu TCC, que eu estava escrevendo com LaTeX, portanto fui instalar um pacote do LaTeX no Mac, e lá se vão mais 1GB de pacotes... Tudo bem, instalei e funcionou beleza. Como já tinham dito, foi meio chatinho configurar o MySql mas funcionou de boas. O homebrew ajuda bastante na tarefa de instalar coisas, é um slackbuilds do futuro, tem várias receitas para resolver os casos de coisas que precisam ser instaladas, e funciona bem. Depois do ambiente todo feito o uso era bem tranquilo, e eu sentia que era bem confortável para usar em coisas que não eram diretamente ligadas com programação. Assistir minhas séries era bem legal, tinha alguns softwares que facilitavam acompanhar algumas séries (TvShowsApp) e até baixar as legendas automaticamente (Subsmarine), o que era bem comodo. Eu tenho trabalhado bastante com HTML5 ultimamente portanto eu mantinha umas 5 versões de navegadores na maquina, e no Mac isso foi bem simples de fazer, apenas arrastando os navegadores para a pasta de Apps e já era. A resolução do Mac no meu monitor externo era fantástica comparada com a que eu tinha antes no Toshiba, apesar de eu não usar muito o monitor externo. O som e vídeo funcionam muito bem, como era de se esperar e apresentações, skype calls e outras coisas eram bem simples e naturais de se fazer. Algumas das aplicações que eu usava no Linux estavam disponíveis no Mac, como o Vim por exemplo, que apesar de ter que instalar o Macvim ele ficava disponível no terminal também. Tive que fazer algumas modificações para que o Vim funcionasse como eu esperava, mas no fim das contas ele estava funcionando normalmente. O GIMP no Mac é bem ruim, e deixa bastante a desejar, até porque ele sobe o X para poder ser executado e foge completamente do padrão do Mac, o que já era esperado, afinal não portaram o GIMP para rodar, apenas emularam o X e rodaram sobre a plataforma do mac (não é só isso, mas o que eu quis dizer é que não é um GIMP feito para mac específicamente, só fizeram ele rodar lá), e isso é bem triste. O tempo passou e eu tive a oportunidade de ir para San Francisco no OpenStack Summit, e eu pensei em trocar de computador, e por coincidência um colega estava perguntando se alguem estava vendendo um Macbook de 13" (!!), não perdi tempo, negociei e vendi por um preço muito bom (tendo em vista que comprei fora do país e vendi por aqui). E comecei a consultar valores de outros computadores para a substituição. Durante essa coleta de preços eu até cheguei a cogitar comprar o Macbook Air, mas eu estava certo de que mac para mim já deu o que tinha que dar, e agora era hora de voltar ao bom e velho Linux. No fim das contas eu comprei o computador que possuía o melhor custo X benefício para o que eu precisava, que é o Acer S3-951-6432, que possui tela de 13", SSD de 256, 4GB de memória, processador i7, leitor de cartão da Realtek, placa wireless Atheros e uma placa de vídeo intel 3000. Dessa vez eu queria usar Linux de verdade, conhecendo tudo o que eu estava utilizando no sistema, portanto resolvi começar a usar Arch Linux</a>, e comecei a saga de instalar cada pacote, desde o sudo, passando pelo ifconfig, X, Awesome e por aí vai. A princípio decidi ficar sem Gnome e configurar o Awesome para funcionar como eu queria, mas no fim das contas eu acabei resolvendo instalar Gnome para facilitar as coisas de vez em quando. Com o Arch Linux</a> eu consigo ter controle de tudo que está rodando e fico sempre no bleeding edge de quase todos os softwares devido a filosofia de rolling updates dele. Aproveitei também para começar a compilar meu próprio kernel, removendo módulos desnecessários e adicionando outros que são necessários para meu hardware como builtin. Não precisei ficar me preocupando com as ferramentas de desenvolvimento, tudo estava fácil de arrumar, e não tive problema algum, foi só instalar o gcc e mandar bala! Para o LaTeX, foi só instalar alguns poucos megas de TexLive e tudo estava funcionando. Pude voltar a usar o bom e velho GIMP, juntamente com o Inkscape e tudo parecia mais feliz. Alguns podiam comentar que eu poderia ter usado o Photoshop no Mac, mas eu to de boas de pirataria, e o GIMP resolve todos os meus problemas...Não quero ficar gastando dinheiro com software que não seja realmente necessário. Conclusão</h3> O Mac não é um sistema ruim, é funcional e bem estável. O que eu constatei com isso tudo é que o Mac apenas não é um Sistema operacional para mim, eu gosto mesmo é de usar software livre, contribuir, customizar, conhecer coisas novas, tentar tunar meu hardware para funcionar melhor, usar Window manager esquisito, compilar o kernel e etc. Outra barreira que caiu foi o Mac nunca travar, ele travou como qualquer outro SO que eu já usei, além de ser um SO muito mais lento do que eu esperava. Muitas pessoas me disseram que isso era coisa do Lion ou que era porque eu tinha só 4 GB de RAM, mas nenhum dos dois argumentos são válidos para mim, se o Lion é uma bosta o problema não é meu, é só mais um motivo para eu parar de usar porcarias, e se eu preciso de 8GB de RAM para poder ficar com um notebook usável, eu prefiro mil vezes usar Linux com 4 GB e ser feliz. A minha opinião final foi que é totalmente possível trabalhar no Mac e programar todas as coisas que se programa no Linux, a diferença é que no Linux é tudo mais natural de fazer mas nada que compilar no mac ou usar o slackbuilds...digo....homebrew... para fazer isso não resolva, portanto ele ficou no mesmo patamar do Linux, cada um com suas vantagens e desvantagens, e as vantagens do Linux me atraem mais do que as do Mac. Ah, e não me venha com historinha que "O legal do Mac é a experiencia". :P Aprendendo com o código do Quake Unknown — Wed, 18 Jul 2012 00:00:00 +0000 Desde que eu terminei a faculdade eu venho lendo bastante coisa útil (foi muita coisa inútil durante 4 anos...) e aprendendo bastante coisa. Nos ultimos meses eu li vários code reviews dos códigos do Quake e do Doom. Os review foram feitos por Fabien Anglard e estão todos disponíveis no site dele http://fabiensanglard.net</a></a>. O primeiro artigo que eu li foi sobre o code review do código do Quake 2 de 1997</a>. Esse quake foi o ultimo que fez Software Rendering e o cara que analizou o código explica direitinho como foi feito, explicando todos os problemas que os desenvolvedores enfrentaram e porque eles chegaram aquela implementação. Para quem é programador e curte Quake é uma ótima leitura. Uma coisa muito interessante que vi na leitura desse artigo foi que eu acabei estudando várias outras coisas para poder entender o artigo, como: BSP trees: http://downloads.gamedev.net/pdf/gpbb/gpbb59.pdf</a></a></li> Octree: http://en.wikipedia.org/wiki/Octree</a></a></li> Memory management: http://www.ualberta.ca/CNS/RESEARCH/LinuxClusters/mem.html</a></a></li> Radiosity: http://freespace.virgin.net/hugo.elias/radiosity/radiosity.htm</a> </a> (esse artigo é animal)</li> </ul> E outras coisas do mesmo genero. Com o lançamento do código do DOOM 3 open source, mais um code review foi escrito: http://fabiensanglard.net/doom3/</a></a>, e nesse review ele explica como a parte de iluminação (que era a grande funcionalidade do Doom 3) foi feita e quais as técnicas foram utilizadas. Apesar de eu conhecer pouco de renderização e algoritmos de iluminação é possível entender uma boa parte desse review. E por ultimo li o code review do código do Quake III</a>, que mostra uma das coisas que eu estava curioso para ler, networking! Todos sabemos que a parte de redes (não somente ela, acho que tudo) precisa de velocidade, e eu queria entender o que os caras planejaram para essa camada, e isso é uma das coisas que o code review traz, inclusive linkando para a análise da antiga engine do Quake e explicando algumas decisões e as premissas simples que foram utilizadas para construir uma camada consistente e deixar o jogo o mais fluido possível. Esse ultimo code review acaba muito legal, linkando para a IA do Quake III, que é muito boa por sinal, e por isso rendeu uma tese de mestrado do desenvolvedor</a> que apesar de eu não ter lido inteira, eu recomendo a leitura para quem se interessa no assunto. Enfim, todos sabem que o John Carmack</a> é um dos programadores que eu mais admiro, e Quake é um dos jogos que eu mais curto, e o código é open source! Esse review era a oportunidade que faltava para conhecer o código melhor e aprender coisas novas. Se você curte jogos e programação RECOMENDO fortemente tirar algumas horas e ler os reviews! Simlinks for ruby on Debian Squeeze Unknown — Tue, 17 Jul 2012 00:00:00 +0000 Every time we need to deploy a new Ruby application on top of Debian Squeeze we need to fix some Ruby depedencies to make the application work as it should. It happens because we're building using rvm instead of the packaged version of ruby, but it needed to be that way in order to use our old build server. I'll keep it documented here: ln -s /usr/lib/libruby-1.9.1.so.1.9.1 /usr/lib/libruby.so.1.9 ln -s /usr/bin/rake1.9.1 /usr/bin/rake ln -s /usr/bin/ruby1.9.1 /usr/bin/ruby ln -s /usr/bin/gem1.9.1 /usr/bin/gem</code></pre> After that run ldconfig</code>. It should make the common ruby commands work again. :) Palestra sobre implementacoes paralelas Unknown — Mon, 16 Jul 2012 00:00:00 +0000 Esse post ficou como draft desde que eu palestrei sobre implementações paralelas, e agora que eu lembrei dele decidi publicar! :) Bem, como eu disse, eu paletrei sobre implementacoes paralelas tanto na Locaweb como no Guru-SP. A idea da palestra vem de um post do John Carmack sobre implementações paralelas, e nesse post ele comenta sobre todos os tipos de implementação paralela que ele já utilizou e as que mais funcionaram para cada tipo de caso. Na minha palestra eu comento sobre todos os tipos de implementacoes que eu ja utilizei e quais delas foram boas ou ruins para determinado caso. </iframe> </iframe> Essas técnicas simples ajudaram a manter nosso código muito mais fácil de manter. Espero que seja útil para mais alguém. ;) XMPP e Ruby Unknown — Tue, 10 Jul 2012 00:00:00 +0000 Alguns (vários…) meses atrás eu fiz uma palestra pequena no Guru-SP(São Paulo Ruby Users Group) sobre Ruby e XMPP, os vídeos e slides estão disponíveis: </iframe> </iframe> Nessa talk eu mostrei como criar dois bots simples e como subir eles na sua conta do Gmail. A Gem blather tem uma DSL bem legal para trabalhar com XMPP em Ruby, mas nos meus testes funcionou muito melhor com ruby 1.9.3 do que com 1.9.2. Para fazer a parte de daemon e gerar uma estrutura para o projeto eu utilizei uma gem chamada daemon-tools, que provê vários metodos úteis para esse tipo de projeto. Se tiverem dúvidas postem aí nos comentários. San Francisco Unknown — Fri, 13 Apr 2012 00:00:00 +0000 I visited San Francisco in 2012. It was my first international trip by airplane (I literally returned from a motorcycle trip to Argentina less than a week before) ever. I went to Openstack conference, as it was something we (the company I worked for) were into at the time. It's been more than 10 years since I went there (writing this in 2023), so take the recommendations here with a grain of salt. 😉 Stay</h2> My friend was living there and I stayed a few days at his house. After that, I went for an Openstack conference and the hotel was paid by the company. The conference happened at the Embarcadero conference center (To be confirmed) and I stayed at the same hotel. As far as I remember, great service and facilities. No idea about the cost x benefit, though. I would probably not stay there if it was paid by me. 😅 Airport</h2> The airport is not close to the city, I remember getting a cab for ~30 minutes to get there. Transport</h2> TBD Places</h2> TBD Food</h2> TBD Viagem de moto para Eldorado na Argentina Unknown — Mon, 09 Apr 2012 00:00:00 +0000 TL; DR Fiz uma viagem de moto saindo de São Paulo e indo para Eldorado (Argentina) , durou uma semana no total e rodei mais de 3000km, esse é o relato da viagem. Quem quiser ver todas as fotos que eu tirei durante a viagem, estão no Picasa</a> Bem, vamos ao relato: Essa foi minha primeira viagem para fora do Brasil e também a minha primeira viagem grande de moto (tinha feito uma de 700km no total 350 contínuo), e é claro que com essas condições eu tava meio perdido para organizar as coisas, preocupado com a moto e etc. Após organizar tudo certinho na sexta a noite tentei dormir cedo porque as 6:00 AM eu deveria estar no posto hungria preparado para sair, isso quer dizer que as 4:30 eu teria que estar de pé. Acho que demorei meia hora para conseguir dormir, mas ainda era 23:30 eu suponho. No dia seguinte eu estava acordado e sem sono às 4:30 amarrando as ultimas coisas na moto e saindo às 5:30 após se despedir dos meus pais que acordaram junto só para me ver saindo :P. No meio do caminho encontrei meu amigo David na imigrantes, ele me acompanhou até o posto hungria de moto para ver a galera saindo. Valeu David! Chegando no posto hungria já tinha 80% das pessoas que iam na viagem e mais várias outras que só foram nos encontrar para desejar uma boa viagem e ver a galera saindo. Fizemos nosso briefing às 6:30, alguem puxou uma oração antes de sair e saimos as 6:40 no máximo. Infelizmente eu não anotei onde foi cada uma das paradas, estradas, kilometros e etc, portanto eu não vou descrever com detalhes o suficiente. Na primeira parada encontramos mais um amigo que sairia de Mairinque e iria com a gente, e nos despedíamos dos que estavam no bonde (bonde == conjuntos de motos) mas não iriam seguir viagem conosco. Após as despedidas seguimos viagem e mantivemos nosso ritmo de parada de mais ou menos 150km. Perto do meio dia nós paramos para comer alguma coisa em Assis (se não me engano) e o sol já estava bem quente, o que me fez tirar a jaqueta e viajar somente de colete. Uma coisa que eu nunca curti foi usar protetor solar para andar de moto , mas dessa vez se eu não tivesse usado eu teria queimado feio os braços, descobri isso porque minha calça sempre voava com o vento e com isso o sol chegava até a perna , o que me causou uma queimadura chata de sol. Segundo o Google Latitude (como não anotei nada e ele ficou guardando, estou usando ele para saber onde eu estava...LOL) chegamos em Maringá por volta das 14:30 e encontramos nosso amigo Walter Santos (a.k.a Wartão :P) no centro da cidade, e ele nos guiou até o hotel araucária, que é onde íamos ficar essa noite. Fizemos check-in e pegamos quartos com duas camas separadas e dividimos, como estávamos em 10 motos pegamos 4 quartos. Tentamos deixar reservados os quartos nesse hotel para a volta mas ficamos sabendo que ia ter um evento e todos os quartos já estavam reservados, portanto quem não reservou com antecedência ia ter que arrumar outro lugar para ficar. Eu não tinha reservado com antecedência e passei em outros hotéis em volta para ver se achava algo, mas os que eram razoávelmente decentes já não tinham vagas, então deixei rolar. O Walter que nos encontrou no centro de Maringá nos chamou para um churrasco em sua casa. Uma coisa interessante é que ele não conhecia nenhum de nós pessoalmente e mesmo assim nos recebeu em sua casa de portas abertas e com um churrasco fantástico. Esse tipo de coisa que me faz acreditar que as pessoas podem ser legais. Saímos da casa do Walter as 23:30 e voltamos para o Hotel. Saímos de Maringá as 8 :30 em direção a Foz do Iguaçu, mas antes passamos na casa do Walter para acordar ele com os barulhos de escapamento e dar um abraço antes da partida, saindo de lá seguimos o mesmo estilo de paradas até foz, 150 em 150km. Chegamos mais ou menos as 16:00 em Foz do Iguaçu e fizemos check-in no Luz hotel no mesmo esquema, dividindo quartos, dessa vez dividi quarto com o Mikele, mas alguns de nós pegaram quartos quadruplos conseguindo um preço mais barato. No começo da tarde chegaram as constelações (cada grupo do ISRA é considerado uma constelação) de Brasília e Goiás no Luz hotel e no total eramos em mais ou menos 25 motos. A noite saimos para jantar num restaurante próximo do hotel, ocupamos uma boa parte do restaurante e causamos uma impressão interessante nas pessoas que estavam lá, fora a cara de espanto (que eu já estava acostumado naquela hora) também rolou um silencio estranho :P. Fui dormir não muito tarde pois pretendia sair bastante no outro dia. Muitos dos que estavam no grupo tinham vindo no ano passado a Foz, portanto fizeram todos os passeios turísticos e não pretendiam faze-los novamente. Eu tinha deixado claro que eu ia para a usina de itaipú e para as cataratas e se ninguém fosse eu ia sozinho mesmo. No fim das contas consegui companhia para ir para a Usina de manhã, fomos em 2 motos, eu com minha Dragstar e o Honda com sua Fatboy. Outras pessoas foram ao Paraguay, Duty free e outros lugares, inclusive, a esposa do Yuri foi com a gente para Itaipú porque o Yuri foi ao Paraguay. A usina de Itaipú é um lugar bem legal e fazer o passeio completo (com visita ao interior da usina) é muito legal para os nerds de plantão, é possível ter informações do funcionamento das turbinas e saber um pouco mais sobre a engenharia da usina, além de algumas curiosidades sobre os funcionários e o acordo entre os países para que a usina funcione. Dentro da usina é possível sentir a vibração que a força da agua causa enquanto ela passa pelos tubos e aciona as turbinas, é uma sensação bem legal (e medonha). Outra vantagem do passeio interno é ir até o eixo de uma das turbinas e ver ele funcionando há quase 100 metros abaixo da superfície. Tirei fotos de todo o passeio, e ta tudo lá no Picasa. Voltamos ao Hotel por volta das 13, almoçamos e fomos para as cataratas, dessa vez em 3 motos, Yuri e sua esposa Ju com uma Suzuki V-Strom, eu com minha DS e o Berlanas com uma Fazer 600. Decidimos apenas fazer o passeio a pé (tem passeio de barco pelas cataratas, mas é mais caro e não rola levar camera) pelas trilhas para conhecer toda a extensão das cataratas e tirar umas fotos. O passeio é muito legal, além de ver as cataratas por vários angulos você ainda se depara com uns quatis que ficam andando pelas trilhas procurando comida dos turistas. Fizemos o passeio completo por mais de 1km de trilhas e tirei muitas fotos (também no Picasa) e valeu muito a pena conhecer o lado brasileiro das cataratas, recomendo! Na saída encontrei um outro motociclista com o colete dos "Bodes do asfalto", não me era estranho esse motoclube e resolvi puxar conversa, acabei descobrindo que ele também estava vindo de São Paulo e estava indo para a Argentina (um pouco além de onde iríamos), mas o mais impressionante de tudo é que ele estava vindo do ABC e trabalha em Diadema! Conversando descobri que ele trabalha a dois quarteirões de onde minha mãe trabalha, e a coincidencia fez eu o encontrar há mais de 1000km de distância! Isso foi bizarro. Na saída das cataratas o pessoal que estava comigo decidiu passar no Duty free e eu não estava afim de ir, portanto voltei sozinho para o Hotel, que é muito bem localizado por sinal, ao lado da rodoviária de Foz do Iguaçu, recomendo esse hotel. No dia seguinte tinhamos marcado de sair as 8 horas mas o nosso grupo já estava muito grande e para todo mundo se preparar ia demorar bem mais do que o esperado. Estacionamos as 25 motos na calçada do hotel enquanto esperavamos a hora de sair. Enquanto esperavamos um onibus foi fazer a curva na rua e encostou na primeira moto, o que causou um efeito dominó nas 3 outras. O motorista do onibus parou e começaram as discussões para resolver . Duas motos foram danificadas, mas nada muito grave, um retrovisor quebrado e alguns riscos e o onibus estava intacto. Todos tinham uma parcela de culpa nesse acidente , essas motos estavam estacionadas muito perto da esquina e o motorista do onibus nem reduziu na curva. Não sei como ficou o desfecho dessa história, mas acho que apenas resolveram seguir para evitar mais dor de cabeça. Enquanto alguns foram numa concessionária para resolver as avarias das motos os outros seguiram em direção a Argentina. Passamos facilmente pela fronteira do Brasil e paramos na ponte da amizade para tirar umas fotos das motos estacionadas no território brasileiro antes de atravessar para a Argentina. Após as fotos fomos em direção a Aduana da Argentina, passamos tranquilamente e ficamos aguardando no próximo posto de combustível disponível. Enquanto estavamos aguardando descobrimos que a Van que levava as malas e as esposas do pessoal de Brasília não conseguiu passar para fronteira da Argentina por alguns problemas e eles teriam que conseguir outro modo de trazer as malas, portanto seguimos para Eldorado enquanto eles descobriam uma melhor forma de passar. Rodamos pouco mais de 100km em direção a Eldorado e chegamos pouco antes da hora do almoço no hotel Don Juan em Eldorado. Pouco tempo depois chegou o pessoal do ISRA da Argentina, cumprimentaram-nos e saímos para almoçar num restaurante brasileiro que tinha perto do hotel. Ficamos no hotel esperando o resto do pessoal chegar, o que só aconteceu as 17:00 mais ou menos. As 20:00 o pessoal da Argentina nos chamou para dar um role pela cidade e saímos me 36 motos pela pequena cidade de Eldorado, estacionando na praça central da cidade . Achei meio estranho esse passeio porque era muito chamariz, e não sou muito fã de ser o centro das atenções, o que era inevitável quando você estava junto com outras 35 motos gigantes e barulhentas que param no meio da praça central da cidade. No fim das contas esse tipo de passeio foi um evento para a cidade, vários moradores se juntando na praça para tirar fotos, perguntando de onde viemos, crianças olhando as motos com cara de admiração e outras coisas. Saindo de lá fomos direto para o restaurante do Ulises que organizou umas pizzas para a galera. Ficamos lá até às 23:00 mais ou menos e voltamos para o Hotel. No dia seguinte quando acordei vi uma movimentação e descobri que algumas pessoas tinham acabado de sair para ver as cataratas do lado argentino, mas já era tarde demais para acompanhá-los, portanto tomei meu café e fiquei conversando com a galera . Resolvemos sair para procurar umas peças para a moto do Yuri e de lá iriamos para um outro lugar com os argentinos, mas no fim das contas ficamos rodando num sol bem quente pelo centro da cidade e não achamos as peças, muito menos saimos com os argentinos , portanto voltamos para o Hotel. Durante as conversas com o pessoal no hotel eu descobri que alguns estavam querendo ir para Wanda ver as minerações e eu fiquei pensando se deveria ir ou não, mas cheguei a conclusão que se fosse para ficar parado eu tinha ficado em casa e fui à Wanda! Fomos em 5 motos: Cidão e Loira numa Midnight 950 Azul, Eu com a DS, Berlanas na Fazer 600, Samuca na DS cinza, Yuri e Ju na Suzuki V-Strom e Totta na Ds vermelha (muito bonita essa moto por sinal!). Wanda é um lugar de minério, e a atração são as pedras semi preciosas que tem nas minas, tirei várias fotos para quem quiser ver . Na saída comprei um triangulo feito de uma pedra azul e 3 brincos de ametista para dar de presente aqui, coloquei no bolso do colete e saimos. No meio do caminho coloquei a mão no colete e só tinha o triangulo, os brincos e meu 100 pesos foram para a estrada ... Fiquei meio triste pela burrice que fiz em ter deixado eles no colete, mas considerei isso como "um gole pro santo" e bola pra frente. Chegando no hotel eu encostei na cama e apaguei por mais de 1 hora, fazia anos que eu não conseguia dormir a tarde, o que mostrou meu meu corpo estava jóia... A noite rolou mais um tour pela cidade com outra parada na praça central, onde rolou umas zoeiras com um colete rosa (entregue a quem for o vigésimo quarto a acessar o fórum mais vezes no ano) e umas fotos das motos e depois fomos novamente para o Ulises, dessa vez comer lasagna. Chegando no Ulises eu vi um colega argentino caindo lentamente com a moto parada, achamos até que era brincadeira, mas a moto inclinou demais na areia e ele não conseguiu segurar (era um Dragstar 1100), nada demais. No dia seguinte acordamos cedo e fomos para as cataratas do lado argentino, dessa vez fomos em mais motos e não vou conseguir citar todas porque um pessoal de Brasilia /Goias foi com a gente, mas estávamos em 7 ou 8 motos mais ou menos. Pretendíamos visitar as cataratas e sair mais ou menos as 13:30 para encontrar nossos amigos que estavam vindo de São Paulo pouco depois da fronteira argentina. Aqui vale um grande parenteses antes de continuar a história, esses nossos amigos saíram de São Paulo na quarta feira, dormiram em Maringá, saíram de Maringá de manhã , chegaram na argentina por volta das 14 e iriam jantar com a gente para poder voltar para SP no dia seguinte. :D Voltando as cataratas, a bateria da minha câmera acabou antes mesmo de começar o caminho a pé para as cataratas, portanto as fotos que estão no Picasa foram tiradas pelo meu celular. Quando vimos o tempo mudando rapidamente resolvemos voltar correndo , mas não fomos rápido o suficiente e ficamos presos no tremzinho esperando a chuva passar (impediram o trem de sair enquanto estivesse com chuva). Quando conseguimos sair já era mais de 14:30 e estávamos atrasados para encontrar nossos amigos. Chegamos no posto onde eles estavam por volta das 15:00 e começamos a viagem de volta para Eldorado (100km mais ou menos) sob chuva fraca. As estradas nesse ponto da argentina são muito barrentas e os caminhões banhávam-nos de barro, o que deixou minha moto praticamente marrom, é como se eu tivesse participado de algum rally com ela. Chegamos no Hotel umas 16:30 mais ou menos e saimos mais tarde para a confraternização oficial do evento novamente no restaurante do Ulisses, onde houve apresentação de todos, entrega de brasões brinde aos amigos e etc. Essa noite estava um tempo chuvoso e um frio durante a noite, portanto esperávamos um clima não muito bom para o dia seguinte. Decidimos que sairíamos as 6 da manhã do hotel rumo a Maringá, não haveria parada longa em Foz dessa vez. Eu estava dividindo um quarto sextuplo (existe isso !?) com o Yuri e a Ju (numa cama de casal no andar de baixo), Mikele e Berlanas. Eu, Mikele e Berlanas ficamos na parte de cima (que só dava para subir utilizando uma escada de Santos Dumont (tem foto dela no Picasa)), e quando as pessoas que você interage são legais não tem como não haver momentos engraçados, como o maldito galo que os caras tinham como despertador do celular. :P Acordamos (com o maldito ringtone do galo) as 5 da manhã, amarramos as coisas na moto e saímos as 6:30 sob uma neblina forte até a fronteira da argentina. Dessa vez o bonde foi dividido em 2, pois alguns de nós acharam que 6 horas era muito cedo para sair e resolveram sair um pouco mais tarde. Atravessamos tranquilamente tanto a fronteira da Argentina como a fronteira brasileira, e o clima esquentou novamente , nada de neblina, só um . Uma das coisas que vai ficar marcada é a sensação de felicidade de estar de volta ao meu país e voltar a ver as placas em português, apesar de eu ficar meio confuso com os idiomas. Paramos para tomar café só em Céu Azul, onde eu ouvia pessoas aleatórias falando em português e ficava todo confuso pensando qual lingua eles estavam falando, hahaha . Seguimos no mesmo ritmo de sempre até Maringá. Antes de chegarmos lá encontramos nosso amigo Walter e sua filha no meio do caminho, eles foram com a gente até o Hotel . Novamente o Walter mostrou a pessoa foda que ele é e nos ofereceu sua casa caso alguem não tivesse quarto no hotel (devido ao evento que eu comentei antes), mas não foi necessário. Eu dividi um quarto com o Mariano. O quarto que ficamos estava com a pia quebrada, por isso rolou um desconto (melhor ainda! :P). Ao chegar no quarto eu apaguei várias horas, quando acordei uma parte do pessoal já tinha saído e só ficou um casal. Quase todos foram de Taxi para a casa do Walter, apenas eu e o Samuca fomos de moto, o Samuca ia sair direto de lá e eu me recuso a andar de taxi numa viagem que estou fazendo de moto. Novamente o Walter fez um jantar esplendido para nós. Sem comentários, a família muito atenciosa conosco, nos trataram muito bem e fizeram o possível para que nos sentíssemos em casa, só temos a agradecer pela recepção, sua família é foda! Eu cheguei, subi para o quarto e capotei. No outro dia tomamos café e saímos as 8 :30 em direção a SP, no mesmo ritmo, mas agora o bonde estava maior, estavamos em 15 motos, e quando mais gente mais difícil manter a organização. Dessa vez não marcamos uma posição fixa das motos, apenas tentamos manter os garupados a frente e as Dragstars depois. Outra coisa que vai ficar muito na lembrança é a felicidade de estar de volta ao meu estado, ver os amigos da frente com o braço para cima apontando para a placa, ou soltando as duas mãos do guidão e abrindo os braços, são cenas que marcam para sempre. No trevo de ourinhos tivemos um pequeno acidente, o Fernando que estava na minha frente entrou um pouco mais rápido na curva e o asfalto não estava nada bom, cheio de ondulações, portanto ele conseguiu frear mas foi jogado fora da pista onde tinha areia e pedras e com isso o freio apenas jogou uma das rodas da Dragstar em uma direção levando os dois (ele e sua namorada/esposa) ao chão. Como eu era o que estava mais próximo, já desliguei minha moto e fui ajudá-lo, levantei a moto para que ele pudesse tirar o pé de baixo e alguém me ajudou a colocar a moto de pé, perguntei se estava tudo bem e ele falou que estava de boas, a esposa dele também, então fomos ver as avarias da moto. A moto só estava com o comando avançado torto (ele sempre salva, foi assim no meu acidente também), que conseguimos desentortar apenas com o peso do corpo e alguns pouco ralados na manopla, ligamos e a moto estava funcionando de boa. Obviamente, qundo a moto ligou rolou um "Aeeee, isso é Dragstar rapá! Não para não!" :). Seguimos até o próximo posto onde já estavamos programados de parar e o Cidão fez um curativo no joelho do Fernando que estava um pouco ralado e foi isso, nada muito grave, apenas algumas dores do impacto com o chão e alguns ralados, nada que os impedisse de voltar de moto para casa. Continuamos viagem e no meio do caminho algumas motos se adiantaram porque o Cidão estava com problemas com primeira e segunda marcha, então foram na frente. Nos despedimos do Tiago, do Ernesto e do Berlanas em uma das paradas, pois cada um ia seguir seu próprio caminho ou pretendia esticar um pouco mais. Seguimos com o ultimo bonde entre 120/130 km/h e paramos para abastecer novamente depois de 140km. Nesse posto o pessoal que seguiu com o Cidão estava parado jantando e muitos decidiram se juntar a eles para fazer o jantar de confraternização. Eu estava planejando passar no casamento do meu amigo Rafael Timbó para lhe dar um abraço de parabens e desejar felicidade nessa nova etapa, mesmo estando todo mulambento da viagem, portanto não fiquei para o jantar de confratermização e segui solo para SP. Chegando na marginal Tietê eu parei para ver onde era o casamento e descobri que era na Serra da cantareira, nunca tinha ido para lá, iria ser uma grande aventura, afinal estava escuro e eu estava há mais de 10 horas andando de moto. Fui seguindo e perguntando, cheguei até o Tucuruvi, peguei a Cel. Sezefredo e segui , pelo que li no site deles, era perto de um tal restaurante Dib, que pelo que me informaram, era uns 13km serra da cantareira a dentro. A informação que eu recebi foi meio medonha: "Vai seguindo, quando vc ver que só tem uma estrada, sem luzes e for arvores dos dois lados é que vc está no caminho certo, quando vc ver a Fernão Dias à sua direita é que ta chegando perto". Ok, vamos nessa! Quando começou a chegar nesse ponto das arvores ficou bem medonho, tava tudo escuro, apenas o farol da moto ligado e o barulho do meu escapamento, a frente apenas curvas bem fechadas iluminadas pelo farol, e acima estavam as copas das árvores com uma fresta que me mostrava a beleza da lua cheia escondida atrás de algumas nuvens, pensei até em tirar foto, mas não podia parar ali era perigoso demais, mas essa cena também via ficar marcada na minha mente por um bom tempo, juntamente com a sensação estranha de estar num lugar desconhecido e desolado. Durante o caminho eu vi algumas plaquinhas escrito "Rafael e Sabrina" que me mostravam que eu estava indo no caminho certo, mas em alguns pontos tinham umas encruzilhadas que era difícil saber qual era o caminho certo, e eu provavelmente peguei o caminho errado em alguma dessas, indo para um lugar mais desolado ainda, depois de uns 5km andando no breu eu encontrei alguma luz, e quando parei para perguntar descobri que nem os seguranças sabiam o nome da rua direito, pqp. Um pouco mais a frente parei um cara de carro e perguntei, ele me falou que eu tinha passado faz tempo e tinha que voltar por essa estrada medonha...Perguntei para ele se a estrada que eu estava vendo a minha frente era mesmo a Fernão Dias sentido São Paulo, e ele me confirmou. Depois de tudo isso tive que pesar, já estava há mais de 11 horas em cima da moto, cansado, e não queria pegar aquela estrada estranha novamente, portanto, com muito pesar deixei de felicitar meu amigo e resolvi voltar para casa, pensando que a serra da cantareira foram os ~15km mais difíceis da minha viagem. Depois de tudo isso, ainda passei pela placa de divisa entre Mairiporã e São Paulo, o que me lembrou a minha viagem para São Thomé das Letras! O que tornou tudo mais interessante, quem diria que no fim de uma grande viagem eu ia sair de encontro com o fim de outra das minhas viagens (um pouco menor naquela ocasião), o que causou várias outras boas lembranças. Vim para casa, passei na casa da minha noiva e ainda chamei ela para dar um role de moto e ir comer alguma coisa (só tinha tomado café, comido uma esfirra e um salgadinho o dia todo), depois de deixa-la em casa fui para a minha e levei tudo para o meu quarto e dormi do jeito que estava...Minha mãe chegou para me dar um oi, mas deixou para o outro dia. Algumas informações legais e aprendizados sobre a viagem: Eu era o mais novo do grupo 23 anos, o mais velho (que eu achei) tem 69, as frases que eu mais ouvi foram: "Você é jovem ainda", "você vai ver quando tiver a minha idade" e etc. Ser o mais novo me permitiu aprender muita coisa com essas pessoas, pegar experiências de viagens e até mesmo experiências de vida que me fizeram uma pessoa muito melhor, além de obviamente me tornar um motociclista melhor. Conversando com a Loira (esposa do Cidão) eu ouvi a frase: "Sempre que eu viajo eu quero conhecer tudo, porque eu provavelmente nunca mais vou voltar nesse lugar". Isso me fez pensar por muito tempo, e realmente é verdade, vou levar para a vida isso. Obviamente não concordamos com tudo que acontece, principalmente quando se está num grupo grande, muitas vezes os meus valores são completamente diferentes dos valores de outra pessoa e com isso sempre vai acontecer coisas que você não gosta ou despreza. No geral, eu posso dizer que essa viagem valeu muito a pena e eu com certeza faria ela novamente, do jeito que foi, ou diferente. E uma coisa que eu posso afirmar é que eu saí de São Paulo com 10 conhecidos de forum , e voltei com 10 (ou mais) amigos. Eldorado, Misiones, Argentina Unknown — Mon, 02 Apr 2012 00:00:00 +0000 I went for a motorcycle trip to Argentina in 2012. The whole description (in pt-BR) can be found here</a>. Stay</h2> I stayed at Hotel Cabanas Don Juan</a> sharing a room with some other people from the motorcycle group I was part of. I don't remember complaining about anything while I was there. Transport</h2> I don't have much to say as I was riding my motorcycle. It was pretty OK to drive there. Places</h2> TBD Food</h2> TBD Palestra sobre Gamedev, Javascript e HTML5 Unknown — Mon, 23 May 2011 00:00:00 +0000 Esse fim de semana eu palestrei no FLISOL de São José dos Campos sobre desenvolvimento de jogos, Javascript e HTML5. Foi uma palestra simples e rápida, durou pouco mais de meia hora (preciso aprender a falar um pouco mais devagar :P) mas foi divertido. A grande maioria das pessoas que estavam assistindo a palestra não eram desenvolvedores, e estavam começando a estudar agora, e acho que por isso não surgiram muitas perguntas sobre o assunto, mesmo eu evitando colocar código. Os slides da palestra foram esses: </iframe> Queria agradecer ao Kesiev</a> pelas dicas sobre o que falar do Akihabara e para os amigos da Plaev</a> pelas fotos para o slide do Rise of theTitans</a>. Um amigo que estava assistindo a palestra fez o favor de gravar para mim: </iframe> Vou colocar mais exemplos e código para as próximas apresentações desse tema. Sugestões e críticas construtivas são bem vindas! ;) Sempre aprender coisas diferentes Unknown — Wed, 27 Apr 2011 00:00:00 +0000 Estou começando a fazer meu TCC agora e resolvi brincar um pouco com LaTeX. Ja faz um bom tempo que eu queria brincar um pouco com ele, entender melhor como funciona e por que tanta gente usa ele e acha legal. Eu tive um pouco de experiência com LaTeX quando estava ajudando a escrever o vimbook</a>, mas não tive contato o suficiente por que entrei no meio do projeto e já estava tudo pronto, foi só seguir a estrutura. O que eu achei interessante nisso tudo foi um dos comentários que eu ouvi: "Por que você não usa o Word, é bem mais fácil". Eu não discordo que provavelmente é mais fácil no Word, apesar de você perder o log de alterações, não ter o arquivo distribuído automáticamente (como eu to fazendo com o Git) e outras coisas. Quem me conhece sabe que nem de Windows eu gosto, mas eu poderia usar OpenOffice e um template e tal. O mais interessante nisso tudo é conhecer várias coisas, saber o que é bom e ruim ao invés de ficar coletando informações de algumas pessoas (que as vezes nem utilizaram para dar opinião) e utilizar isso como "conhecimento" da tecnologia. Se você resolve perguntar para uma pessoa dessas se ela conhece textile, markdown, LaTeX ou qualquer coisa do genero, ele vai responder que não, ou seja, o maledeto só conhece o Word e considera isso a melhor ferramenta do mundo, não tem nem como argumentar sobre mais nada por que nunca usou. Enfim, esse foi apenas um caso besta que aconteceu comigo, mas isso acontece com muita coisa, como programação por exemplo! Pessoas que só usam Java, ou só usam Python, ou só usam Ruby, ou qualquer outra, e vem falar da outra linguagem apenas se baseando no que ouviu falar, sem nem mesmo ter usado para sentir os problemas e as vantagens da linguagem. E mais uma vez, esse foi só mais um exemplo, isso acontece muito ultimamente, pessoas que simplesmente querem "dar sua opinião" sobre uma coisa, independente se conhecem ou não essa coisa. Se quer mesmo dar sua opinião, tenha pelo menos algum conhecimento prático (mesmo que seja básico) sobre o assunto, ou então STFU. :) Instalando o Full Throttle no Motorola Milestone Unknown — Thu, 03 Mar 2011 00:00:00 +0000 </a> Logo depois que eu comprei a minha Dragstar 650</a>, me deu uma grande vontade de voltar a jogar full throttle (por que será, né?), e eu comecei a procurar uma forma de fazer isso. Eu tenho o jogo (o CD-ROM mesmo) ripado no meu computador, e agora só faltava emular ele. Procurando na internet eu achei o scummvm</a> que emula os games da LucasArts</a> em várias plataformas! Baixei o .deb e comecei a jogar no Ubuntu. Rodou bonitinho e estava gostando pra caramba! Depois de jogar um pouco eu me toquei que eu não tenho tanto tempo para parar na frente do computador e ficar jogando, e não é nada prático ficar levando meu notebook para lá e para cá, portanto eu precisava de uma maneira mais portátil de jogar o game, e consequentemente isso me levou a pensar em como fazer o game funcionar no meu Android (um motorola milestone). Procurando no site do scummvm eu encontrei um build para Android (um .apk, bonitinho)</a>, mas ao tentar instalar no Milestone ele não funcionou, devido as modificações na versão do NDK, pois a versão oficial do build que está no site é um pouco antiga. :( Procurando nos fóruns por ae</a> eu encontrei uma versão feita em cima de um commit mais recente</a> do antigo svn (agora eles estão usando Git e o projeto está no GitHub</a> \o/) do scummvm. Baixei o .apk e instalei no Android. Após algumas configurações do SDL tudo funcionou beleza e o scummvm abriu bonitinho! Agora é só colocar o meu full throttle ripado no SD e falar para o scummvm dar o load. Seja bem vindo ao mundo dos polecats novamente! :D Viajar de moto com um grupo de motociclistas Unknown — Tue, 25 Jan 2011 00:00:00 +0000 Pois é! Essa era uma das coisas que eu tinha vontade de fazer há muito tempo, mas não queria ir de Intruder 125, e agora o momento chegou. :) Depois que comprei o monstro (apelido da minha Dragstar 650), a vontade de viajar de moto aumentou muito, afinal, montar sobre 650cc com 40HP para andar por bairro é zuado! :P Aproveitei o natal e fui com uns amigos para Itanhaém, eu sozinho na moto e eles de carro. Curti bastante a viagem, e foi muito bom para descabaçar de pegar a estrada, mesmo que seguindo um carro! Essa viagem me rendeu uma foto bem legal</a>, e foi a oportunidade de ver como o monstro se comporta em uma velocidade mais elevada (cheguei a 145km/h em uma reta e reduzi depois, não curto correr muito, mas precisava testar). Depois de ter feito uma viagem sozinho é a hora de procurar uma viagem em grupo! Para isso estava acompanhando o fórum dos (novos) amigos do DragstarOnline</a>, do qual faço parte antes mesmo de comprar a moto, e já estava me sentindo um dos DOGs (Dragstar Owners Group :P). Acompanhando sempre o fórum eu encontrei a oportunidade de fazer o primeiro passeio com a galera! No dia 23 de Janeiro de 2011 marcaram um BV (bate e volta) para Peruíbe! Lá vou eu para o primeiro ponto de encontro (no Frango Assado da Imigrantes) as 8:00 da manhã do domingão! No fim das contas esse primeiro passeio em grupo foi algo meio surreal para mim! Encontrar pessoas que ainda não conhecia pessoalmente, em um lugar que nunca tinha ido para ir para outro que só tinha uma vaga noção de onde era. Se sentir parte do grupo em poucos segundos de conversa, como se o pessoal me conhecesse há vários anos. Atualmente eu tenho visto tantas pessoas escrotas por aí que quando eu encontro um grupo de pessoas legais até parece que é um universo paralelo, e eu estou literalmente viajando nesse mundo "novo". Ao se preparar para sair, após alinhar as motos, é muito legal ouvir todos os escapamentos roncando ao mesmo tempo construindo aquela sinfonia que precede um grande evento. Partir com os amigos pela estrada mantendo a formação e repassando os gestos para alertar os companheiros que te seguem. Encontrar no transito olhares curiosos e admirados das crianças dentro dos carros, mas não apenas delas, outras pessoas que fotografam e acenam de dentro dos carros ou do acostamento da estrada. Se tornar atração do nosso destino na hora da nossa chegada e observar os olhares incrédulos ou curiosos das pessoas que observam atentamente 15 motos tentando se endireitar em um estacionamento esquisito. Ter algumas horas para bater papo com os novos amigos e aproveitar a paisagem até o momento de alinhar novamente para voltar para casa. Enfim, o que eu posso dizer é que viajar de moto com um grupo de motociclistas é algo muito foda, e esse primeiro passeio com certeza não será o ultimo! :) Postei no Picasa algumas fotos do BV</a> PotHix e as motos Unknown — Tue, 25 Jan 2011 00:00:00 +0000 Bem, para introduzir um assunto sobre os meus Hobbies aqui no blog eu vou falar um pouco da minha história com motos. Eu nunca gostei da idéia de ter um veículo, mas na época que eu comecei a trabalhar mais longe e fazer faculdade eu estava gastando 4 horas diárias dentro de onibus, e isso estava me incomodando bastante, mesmo eu ouvindo podcasts todos os dias eu ainda considerava isso como tempo perdido. No fim das contas eu me decidi que precisava ter um veículo! E como naquela época eu já tinha noção que ter carro em SP é totalmente inviável eu resolvi tirar carta de carro e moto (com 20 anos eu não tinha carta...Dá para ver como eu não ligava nem um pouco para isso :P), para poder comprar uma moto. Após terminar todos os exames eu estava esperando a minha carteira de habilitação chegar, e enquanto isso eu fui para a fase de escolher uma moto para comprar. Nessa época já era sabido que eu ia preferir uma moto com modelo custom, mas eu não podia (nem achava sábio) comprar uma moto grande para ser minha primeira moto, afinal, além de tudo, eu nem sabia se eu ia gostar ou não. Tendo isso em mente, eu fiquei em duvida entre a Kansas da Dafra e a Intruder da Suzuki. As duas motos são de baixa cilindrada (150 e 125 respectivamente). Após muitas pesquisas fiquei com "um pé atrás" para pegar a Kansas (apesar de achar ela mais bonita) e resolvi comprar uma Intruder por que já tinha ouvido falar muito bem, além de ser da Suzuki. E após começar a passear de moto eu comecei a descobrir que eu realmente gostava disso! E já estava pensando em customizar a minha intruder, comprando alguns acessórios diferentes e tal. Após comprar o sissybar (encosto para o passageiro) eu fiquei pensando que era melhor deixar para investir na minha próxima moto, por que naquela época eu já estava pensando em trocar após um ano para uma outra moto um pouco maior. Veja no meu album do Picasa as fotos da trudinha</a>. Dois anos se passaram e a Intruder me ajudou bastante, sempre me levando para o meu destino com rapidez e me dando pouco custo de manutenção (em torno de 20 reais por semana de gasolina e uns 30 por mês de manutenção periódica dos quase 1000km que eu rodo mensalmente). Nesses dois anos eu me tornei um motociclista mais hábil e agora estava preparado para comprar uma moto maior. Por um tempo eu tentei dropar a idéia de pegar uma moto maior, por vários motivos, sendo o maior deles o custo x benefício. E atrasei a idéia por vários meses, mesmo sempre estando com ela na cabeça. Eis que no final do ano passado eu resolvi olhar o preço das Dragstars (que sempre foi o meu sonho de consumo) e fiquei louco para comprar uma, portanto aproveitei essa loucura para parar de pensar em custo, e tudo mais para comprar, por que se eu não me enganasse eu não comprava mais :) Depois de muita cotação eu comprei uma Dragstar 650 com apenas 9000km rodados, e totalmente original. As fotos do monstro também estão no Picasa</a>. A sensação de pilotar essa moto é completamente diferente da Intruder, inclusive o sentimento, não gosto de pilotar ela na correria do dia a dia, e sim quando eu quero realmente aproveitar todo o trajeto que eu estou fazendo. Enfim, esse foi só um post para introduzir essa "seção" do blog, que é um dos meus Hobbies :) Organizando os Feeds do Blog Unknown — Mon, 24 Jan 2011 00:00:00 +0000 Como muitos sabem, eu sou meio doido por organização (heheh) e eu mesmo não gosto de ficar lendo coisas que não me interessam de outros blogs, ou seja, no blog de alguém que gosta bastante de Vim eu ter que ficar lendo sobre paraquedismo :P Agora eu gostaria de além de escrever sobre coisas técnicas, escrever também sobre os meus outros hobbies, como Motos, Shows e etc. Alguns deles eu até já escrevia um pouco antes, mas nem tanto, e isso já me incomodava um pouco, por que eu sei bem que várias pessoas que seguem o feed não gostam das mesmas coisas que eu. Então minha idéia foi simples, criei um feed só para os posts técnicos (programação, Vim, eventos de tech, e coisas relacionadas), e o que eu achar que não é tech eu não coloco a tag. Portanto, se você só quer ver os posts técnicos do meu blog, assine este feed</a>, e o feed atual começa a ser o "FULL" onde terá todos os posts. :) Se você não liga para só ler posts técnicos e quer ler tudo que eu colocar, é só ignorar isso tudo :) Meu ambiente de desenvolvimento Unknown — Wed, 29 Dec 2010 00:00:00 +0000 Fui convidado pelo @jtadeulopes</a> e pelo @qmx</a> para participar do meme sobre ambientes de desenvolvimento, então estou fazendo esse post para falar um pouco mais sobre o meu. Sistema Operacional</h4> Já usei Windows um bom tempo atrás, e agora tenho um pós-conceito para usar (preconceito é só quando vc não conhece), não vejo nenhuma vantagem para utilizar ele e acho que não vale o preço (tenho um Vista e um Win7 originais que ganhei na compra do notebook e na CampusParty e nem uso). Já usei Slackware (e ainda tenho ele instalado no meu notebook para brincar de vez em quando) e atualmente estou utilizando só o Ubuntu, que me fornece um ótimo ambiente para desenvolvimento. Acho muito fácil instalar coisas novas para dev com o Ubuntu, e tudo se encaixa muito bem com esse SO. Controles de Versão</h4> Já utilizei um pouco de SVN, Mercurial e Bazaar, mas não o suficiente para falar bem ou mal de qualquer um deles, por que quando eu utilizei eles supriram a minha necessidade tão bem quanto o Git. Atualmente utilizo muito o Git, que eu acho fantástico, e a cada hora que vou utilizando eu descubro coisas novas que me surpreeendem. Não utilizo nada gráfico para o Git, apenas linha de comando, afinal, do que mais eu preciso!? :D Linguagens de Programação</h4> Gosto de brincar com várias linguagens e sempre estou mexendo um pouco com Python e Javascript. Já faz um tempo que eu não brinco com C++, mas é outra linguagem que eu gosto bastante também. Algum tempo atrás brinquei um pouco com desenvolvimento de aplicações para Android e para isso tive que brincar um pouco com Java também :). Mas como todos sabem, a linguagem de programação que eu mais uso atualmente é Ruby, que uso no trabalho e para alguns projetinhos pessoais. Editor de texto / IDE</h4> Eu uso o único editor de texto que uma pessoa em plena sanidade poderia usar, ou seja, o VIM! heheheh :D Saindo da trollagem e voltando as vantagens, eu gosto do Vim por que ele é um editor rápido, customizável, e me faz pensar a todo momento. Para mim é estar resolvendo puzzles a cada minuto, acho divertido ficar pensando em como eu poderia estar editando aquele texto de uma forma mais divertida, e consequentemente, quanto mais eu aprendo a editar textos de uma maneira melhor mais rápido eu vou ficando para editá-los. Claro que não é viável utilizar o Vim para tudo (apesar de eu estar escrevendo esse post por ele...heheh), e para algumas coisas é mais viável utilizar uma IDE. Para desenvolvimento de apps para o Android por exemplo, é muito mais fácil desenvolver utilizando o Eclipse que já tem plugin que ajuda em algumas tarefas, e é Java...Não preciso dizer mais nada. Musica</h4> Sempre estou com meu player aberto ouvindo musica, e sempre estou ouvindo coisas diferentes, começo com um random na minha lib inteira e escolho uma banda nesse meio para ouvir. Eu tenho uma playlist das musicas que eu mais curto para ouvir nos dias que não estou afim de ficar ouvindo coisas aleatórias. Já testei diversos players no Linux (banshee, amarok e etc), e atualmente estou utilizando o Rhythmbox, que reconhece meu Ipod e posso ouvir sempre a mesma lib em casa e no trabalho. Se quiser saber as musicas que eu ouço veja meu last.fm</a>. IMs</h4> Geralmente fico logado em mais de 6 contas de IM (2 Gtalks pessoais, 1 Jabber da empresa, 2 contas de IRC, 1 conta de Skype e ainda tem o softphone). Parece ser meio bizarro ficar logado em tudo isso todo o tempo, mas eu só consigo essa proeza por que as pessoas que eu tenho nos IMs são inteligentes o suficiente para olhar o meu status e não em encher quando não devem, caso não eu não possa falar apenas aviso e pronto. Em casos que preciso de bastante concentração eu fecho quase todos, deixando apenas uma conta que tem só algumas pessoas adicionadas :) Só para constar, se você usa MSN isso não funciona, por que se a pessoa usa MSN ela já não tem nenhuma noção. Terminal</h4> Aqui é onde eu passo 90% do meu tempo de trabalho, utilizando linha de comando, Vim (não uso interface gráfica para ele também...Não faz sentido para mim), Git e scripts em geral. Atualmente eu uso o gnome-terminal do Ubuntu, que não deixa a desejar. :) Organização</h4> Eu sou meio bizarro quanto a organização, e no meu ambiente tudo tem que ficar em seu devido lugar, assim, cada atalho de teclado me leva onde eu sei que as coisas estão. No trabalho tenho 2 monitores e 4 areas de trabalho, sendo que fica organizado assim: Um browser em cada monitor</li> </ol> Firefox com Vimperator na esquerda com 3 abas com páginas que eu uso no sistema que eu trabalho atualmente</li> Chrome no monitor da esquerda com 2 e-mails, todoist e pivotal tracker</li> </ul> Todos os IMs e um terminal</li> Dois terminais, um em cada monitor com projetos auxiliares</li> Dois terminais, os dois abertos com o projeto que estou trabalhando</li> </ol> No terminal da direita deixo uma aba com Rails server, uma com Rails console e uma para o Vim</li> No terminal da esquerda rodo testes e outras coisas</li> </ul> Tem várias outras coisas que uso (como o Notecase para tomar notas por exemplo) mas acho que isso ae já é uma visão geral :D Agora eu passo a bola para o @dlibanori</a>, @crocidb</a> e @sceadugenga</a> Semana de eventos (#rubyconfbr, #adl e #gddbr) Unknown — Sun, 31 Oct 2010 00:00:00 +0000 Na semana passada (semana do dia 24 ao dia 30 de outubro) foi uma semana de grandes eventos, que eu tive o prazer de participar de todos! :) Rubyconf Brasil</h4> A Rubyconf Brasil</a> é o Antigo Rails Summit Latin America, que acontecia no centro de convenções do Anhembi, e agora mudou sua localização para o centro de convenções Frei Caneca, para diminuir os custos e prover um local mais acessível para os participantes (próximo ao metrô e a avenida paulista). O evento foi muito bom, contando com mais de 20 palestras com um número bem equilibrado de palestrantes nacionais e internacionais, que ministraram muitas palestras com ótimo conteúdo técnico. Infelizmente o evento teve problemas com WIFI, e os participantes mal conseguiram acessar a internet utilizando a infra do evento. Algumas palestras: A palestra do Jim Weiric sobre SOLID Ruby foi fantástica! Além dele ser um ótimo orador, muito divertido, mostrou conceitos bem interessante e algumas comparações com outras linguagens. Uma das melhores palestras do evento. </li> O tenderlove</a> mandou muito bem na sua palestra sobre Fibers e ruby 1.9. Além das corriqueiras brincadeiras com fotos sobre a suposta criação da palestra, ele mostrou um conteúdo muito interessante, com muitos exemplos préviamente contruídos para demonstrar o conceito de Fibers. Uma palestra densa mas muito boa! :) </li> O José Valim</a> palestrou sobre Rails 3 e mostrou algumas das novas funcionalidades e também o que estar por vir, e como sempre deixou a dica para a galera contribuir, "as próximas features depende de vocês" :) </li> O Yehuda Katz</a> fez uma palestra bem interessante sobre como melhorar a performance da sua aplicação movendo muito de sua lógica para o cliente, e apresentou um projeto que ele está trabalhando atualmente. Gostei do conceito, mesmo pensando que não é um conceito para aplicar para qualquer aplicação web, mas para um aplicação com muitos acessos faz muitos sentido e o modelo parece bom. :) </li> O pessoal da Caelum Anderson Leite</a> e Guilherme Silveira</a> apresentaram sobre como utilizar uma Ruby funcionalmente, e a palestra foi muito boa, apesar de ser bem densa e os dois falarem rápido </li> </ul> Tiveram outras ótimas palestras, sobre encoding do Ruby (que é bizarro assim como qualquer outra implementação de encoding), integração de redes sociais, redis e resque e etc. Não vou falar de todas aqui para o post não ficar muito grande, mas aconselho a ficar de olho nas notícias pois a Locaweb</a> filmou o evento e provavelmente vão liberar os vídeos das palestras, e quando isso acontecer, aconselho você a assistir! :) E é claro que nesse evento também teve um espaço para a desconferência, onde apareceram algumas outras apresentações legais (cômicas ou não), sobre assuntos derivados, como: node.js, deploy continuo, programando algo parecido com Ruby para Java, e etc! Foi bem divertido também! Além de tudo isso ainda temos que contar o networking com a galera que foi fantástico, rever velhos amigos que quase nunca vemos (a galera da Fande</a> e do Ikwa (@mateuslinhares</a>, @danielaltman</a>, @jorge_silveira</a>, @willian</a>, @_bojak</a>, @rafaeltimbo</a> e @vitormateus</a>) por exemplo), reencontrar o pessoal do Guru-SP</a> que apesar de encontrar sempre é legal reunir toda a galera e foi mais um encontro :), e ainda tem mais um monte de gente que encontrei por lá, e isso fora as pessoas que conheci! Enfim...Networking #FTW! :). Minhas fotos do evento</a> Android Dev Lab</h4> Eu sinceramente esperava que o Google fosse dar um Nexus One para a galera assim como eles fizeram na OSCon lá fora, mas obviamente me enganei :P. No fim das contas o evento foi razoável, apesar dos problemas com WIFI (que já é corriqueiro...), foi interessante para conhecer um pouco do SDK, principalmente para quem não ia no Google Developers Day no dia seguinte (o que não foi o meu caso), e para ganhar uma camiseta bonitinha do Android :P Resumo: Foi legal mas eu esperava mais. Minhas fotos do evento</a> Google Developers Day</h4> Para compensar o Android Dev Lab o GDD foi um evento fantástico! Muito mais gente (como era de se esperar) poucos lugares nas palestras principais, mas um ótimo conteúdo de palestras (se você souber escolher bem :D). Algumas palestras: Para mim foi quase um Tim Bray Developers Day, por que eu assisti 3 palestras do Tim Bray, todas sobre Android, direta ou indiretamente. Gostei de todas, o Tim falou muito bem sobre os temas que escolheu. Deu uma boa visão sobre design de aplicações, sobre o Android em si (algumas coisas eu já tinha visto no dia anterior...), e mostrou por que eles seguem algumas filosofias. </li> Uma frase que ele falou que eu ia mencionar no twitter na hora mas não ia caber, e resolvi deixar para (trollar aqui n)o post: </li> "O Android Market não precisa de moderação por que sabemos que as pessoas são inteligentes e caso uma aplicação não seja boa ou pareça maliciosa, eles simplesmente não instalam e não usam" </li> A palestra sobre Desenvolvimento de extensões para o Chrome foi bem legal e mostrou como é simples desenvolver uma extensão e como ele consegue acesso fácil ao chrome apenas utilizando Javascript. E o mais engraçado é que o desenvolvedor do Chromed Bird fez uma pequena apresentação mostrando a extensão dele e ele tinha uma direct message com um link para um twit meu. Vai saber :P </li> Achei que a palestra sobre HTML5 seria a mesmice de sempre, mas aprendi muita coisa interessante com ela! Não sabia que agora existem buscas no estilo jQuery nativamente no Javascript. Algo como .search('#id') (não é esse método, mas existe), fora as dicas que ele deu e os exemplos que ele mostrou que valeram a pena. Vou procurar a apresentação dele na internet depois para dar uma olhada novamente, e se eu encontrar atualizo o post. </li> </ul> Novamente, teve outras palestras legais, mas essas são as que eu lembro, e aproveitei! :) Nesse evento também encontrei velhos amigos como o Rubens Altimari</a> da Whitehat</a> empresa que eu já tive o prazer de trabalhar, e meu amigo Bruno Assis</a> que sempre marcamos de conversar e nunca nos encontramos :P. Minhas fotos do evento</a> Resumo</h4> Foi uma semana Muito cansativa, fazia tempo que eu não ficava tão cansado assim. Entre um evento e outro teve as minhas seções de fisioterapia (para curar umas dores nas costas devido a uma queda), e também trabalhei bastante para compensar os eventos (e o mais legal é que foi uma parte divertida do trabalho para fazer!). No fim das contas, tudo isso valeu muito a pena, aprendi bastante, conheci pessoas, revi outras pessoas, consegui manter o fluxo do meu trabalho, e descansei no final da semana! Portanto... Vitória! :D Conto da migração para Rails 3 Unknown — Thu, 21 Oct 2010 00:00:00 +0000 Nesse post eu vou falar um pouco de como foi atualizar a aplicação que eu trabalho atualmente para Rails3. Em uma segunda feira eu tive a brilhante ideia de aproveitar que as tasks que eu estava fazendo estavam dependentes de algumas coisas que ainda não estavam feitas, e resolvi começar a atualizar a aplicação para Rails3 só para saber o trabalho que ia dar, e no final do dia eu já tinha feito todas as alterações necessárias para o boot da aplicação e para rodar a suite de testes (não fazer os testes passar, apenas rodar!). Depois disso foi mais 1 dia para fazer todos os testes passar, e mais alguns outros testando a aplicação e resolvendo pequenos problemas de safe html e derivados. Dicas para fazer a conversão do código</h4> Tenha testes</h5> Se não tiver testes, esqueça essa idéia e pare de ler o post, a menos que você queira quebrar sua app em produção. Faça sua aplicação e suite de testes funcionar</h5> Primeiramente, se você ainda não conhece, vale a pena dar uma olhada no plugin chamado Rails Upgrade que te dá um guideline do que você precisa ir alterando para tornar sua aplicação compatível com Rails 3. Esse plugin faz algumas coisas como criar o application.rb baseado no seu environment, te dar alguns guias das configurações que mudaram e tenta converter suas rotas para o novo padrão (vide próximo tópico) O primeiro passo a se tomar é utilizar o plugin (ou não, pode fazer manualmente também) e trocar as coisas principais para que sua aplicação pelo menos passe pela etapa de boot. Quando passar por esse passo vá para seus testes, e se for RSpec prepare-se para ter alguns problemas de conversão, por que algumas coisas mudaram do RSpec 1 para o RSpec 2, e você vai ter que lidar com os problemas de atualização dos seus testes tambem. A maioria das coisas que tive problemas foi com métodos que não existem mais como o have_tag por exemplo. Não use o Rails Upgrade para a conversão das rotas</h5> Como disse acima, esse plugin é um ótimo guia, mas tome cuidado com ele como solução final. Você pode dizer para ele converter suas rotas, mas tome cuidado, por que dependendo da forma que as suas rotas estão diagramadas o resultado que ele dá não é muito conciso. O que eu fiz foi utilizar a conversão dele apenas como estudo para saber como está a nova syntax e refiz o arquivo de rotas do zero. Pare de usar remarkable</h5> Eu sempre gostei de usar Remarkable para testar relacionamentos, validações e etc, mas remarkable no Rails 3 é uma grande porcaria. Os desenvolvedores que começaram o projeto ficaram sem tempo para o mesmo e deixaram na mão de outros, que não tem a mesma qualidade ou preocupação com o projeto, portanto, a menos que você queira ser o novo mantenedor do projeto e fazer as alterações necessárias para que funcione bem no Rails 3, fuja dele agora. O que eu fiz foi começar a usar o Shoulda para algumas coisas que me convinham, como por exemplo testes de relacionamento e validações. Para quem estiver interessado em fazer essa migração, eu fiz grande parte das trocas do que eu usava (validações e relacionamentos) facinho com grep e sed! Fiz um Gist</a> disso. Evite dependencias</h5> Assim como o remarkable acima, cada outra gem/plugin que você está utilizando pode ter problemas com o Rails 3, portanto, antes de fazer a migração procure manter o menor número possível de dependencias no seu projeto, e as que você tiver veja se já possui uma versão funcional para Rails 3, e se não possuir você já pode se voluntariar para fazer ;). Use o sufixo _html nos locales necessários</h5> Suponho que as aplicações Rails estão usando os formatos de internacionalização do Rails, portanto suas string não estão perdidas pelas Views, Controllers e Models e sim estão em seus devidos arquivos de locale. Levando esse cenário óbvio em conta lembre-se de que você não precisa dar raw em toda mensagem que possui HTML por que Rails já faz isso para você quando você adiciona o sufixo _html na sua chave de locale. Exemplo: not_yet: "Ainda não"</code></pre> Ficaria: not_yet_html: "Ainda não"</code></pre> E assim ele não vai escapar automaticamente o HTML dessa chave. Vá lidando aos poucos com DEPRECATION WARNING</h5> Quando você rodar sua suite de testes pela primeira vez já vai ser bombardeado por uma quantidade monstra de _DEPRECATION WARNING_s, mas não saia atacando eles de uma vez, primeiramente tenha em mente fazer sua aplicação funcionar e você vai corrigir esses probleminhas aos poucos enquanto estiver corrigindo os erros ou desenvolvendo coisas novas. Felizmente a API do ActiveRecord não deixou de funcionar, portanto você ainda não vai precisar fazer grandes modificações para a nova syntax utilizando Arel por enquanto, o que vai tornar a migração menos dolorosa e você pode migrar aos poucos enquanto seu código já estiver rodando. Dicas de organização para a migração</h4> Crie um branch separado e altere aos poucos</h5> Sim! Todos queríamos que toda a equipe parasse por alguns dias e fosse alterar o projeto para funcionar com Rails 3, mas todos sabemos que isso não é possível na realidade de ninguém. Então uma coisa legal para se fazer (principalmente quando se está trabalhando com controle de versão distribuído, onde branches não são tão penosos) é criar um branch e manter uma pessoa trabalhando nele enquanto os outros vão tocando o projeto, sempre com muita comunicação para evitar que as pessoas criem cada vez mais código legado que precisará ser migrado, até que chegue uma hora que você possa voltar para o master e ficar sem deploy por alguns poucos dias para que a aquipe termine o trabalho e faça alguns testes. Ataque um problema de cada vez</h5> Acho muito legal a combinação Rails + Ruby1.9, mas acho que as coisas ficam bem mais fáceis quando atacamos no estilo estripador (por partes), assim você tem um caminho a menos para analizar de onde vem o possível erro, e assim que terminar uma migração para Rails 3 já pode começar uma para Ruby 1.9 e ver o que vai quebrar apenas para essa implementação específica. Use seu ambiente de homologação</h5> Não sei como seu deploy funciona atualmente, mas talvez com a migração você precise alterar ele e é na hora que você for colocar no seu ambiente de homologação que você vai descobrir isso, portanto, use-o bem! :) Conclusão e Saldo final</h4> Fazer a migração para o Rails 3 foi mais simples do que eu imaginei, mas mesmo assim tomou vários dias para a conclusão. Nos meus calculos levou mais ou menos 2 dias só meus e uns 3 dias meus e de outro desenvolvedor, isso contando os problemas de merge e etc. Portanto acho que em 1 semana é possível migrar uma aplicação bem coberta por testes sem grandes problemas e sem precisar parar a sua equipe inteira por um grande período. Escolha aquela semana com um feriado e atualize sua aplicação. :) Fluxo de leitura e o Android Unknown — Wed, 08 Sep 2010 00:00:00 +0000 Quem me conhece sabe como eu sou meio doido quanto a ler coisas aleatórias (Google reader e artigos interessantes que eu acho perdidos por aí), e como eu tenho um tempo um pouco limitado, devido ao trabalho e a faculdade eu sempre tenho alguns esquemas diferentes para ler. :P Fluxo de leitura</h4> Depois que eu comprei um Android o meu fluxo de leitura se modificou um pouco. E está da seguinte maneira: Aproveito o café da manhã para dar uma revisada no meu Google Reader pelo celular, colocando estrela nos artigos que me interessam</li> Termino de separar os artigos e colocar estrela nos que me interessam e marcar como lido os que não interessam</li> Leio os artigos pequenos que estão com estrela e os artigos maiores vão para o Android</li> </ul> E com isso eu consigo pegar meus "tempos livres" para ler um pouco desses artigos aos poucos. Aplicações para Android</h4> Quando comprei o celular já estava pensando em conseguir aplicações legais para leitura justamente para ajudar a resolver esse meu "problema", portanto fui atrás logo cedo. Minha primeira idéia era simplesmente colocar um .pdf no Android e ler em qualquer leitor de PDF normal, como o quickoffice ou até mesmo o adobereader para Android. Seguindo o caminho PDF eu descobri que é um pouco desconfortável ficar lendo PDFs em uma tela pequena, e vc precisa ficar fazendo scroll com frequencia, dar zoom e etc, e isso deixa a leitura meio enfadonha (sempre quis usar essa palavra :P). Então decidi seguir outro rumo não muito comum, vou transformar esses artigos em .epub e ler em um leitor de epubs para Android. Os dois leitores legais que eu encontrei foram: Laputa</a></li> Aldiko</a></li> </ul> Primeiramente tentei algo com o Laputa que parecia um iBooks para Android. Todo cheio de frescuras de desenhar quando você está virando a página para parecer um livro e tal, mas eu prefiro as coisas mais simples :). Ao mesmo tempo já estava testando o Aldiko tambem e comparando funcionalidades. O Aldiko tinha as mesmas funcionalidades só que com menos frescuras e algumas coisas a mais que realmente fazem a diferença, como o ajuste de brilho tocando o lado esquerdo da tela, por exemplo. E no fim das contas acabei decidindo usar o Aldiko como meu leitor padrão, por ter boas funcionalidades e não ter frescuras. Mas depois disso ainda tinha um problema para resolver...Tinha que transformar em .epub e colocar no Android toda vez que eu quisesse ler um texto nele, e isso provavelmente ia ser uma tarefa muito chata...Se não fosse o Calibre! :D Calibre</h4> O Calibre é uma aplicação para organização de ebooks que provê uma maneira fácil para editar metatags e exportar para diversos formatos. A ultima versão (se vc usa Ubuntu, não instale por apt-get que a versão é antiga, instale diretamente do site</a>) reconhece perfeitamente o meu Milestone e envia para a pasta eBooks/import, que é a pasta que o Aldiko usa para importar ebooks! :D Portanto, utilizando essas ferramentas ficou muito fácil de seguir o meu fluxo de leitura: Ler um artigo com estrela</li> Se for grande imprimir em pdf (geralmente uso um plugin do Chrome chamado iReader, que formata muito bem para leitura/impressão)</li> converter o .pdf para .epub no calibre e já enviar direto para o Android</li> no Aldiko importar os novos livros</li> </ul> E pronto! Agora tenho os artigos que eu quero ler em boa fonte, como se fosse um ebook comum! :) Espero que seja útil para mais alguem. Motorola Milestone e Android Unknown — Wed, 08 Sep 2010 00:00:00 +0000 Muita gente tem me perguntado sobre o meu Android atual, um motorola Milestone, e resolvi postar algumas informações e opiniões sobre o aparelho e sobre o Android em si. Primeiramente, gostaria de dizer que o Android é um sistema muito bom, e estou bastante satisfeito com as features, apps, SDK e etc. Milestone</h4> É um aparelho bem legal e na minha opinião é o Android mais "custo X benefício" do Brasil. Tem um hardware bom o bastante (processador 600 Mhz e 256 de RAM), que já dá para rodar alguns joguinhos legais e deixar o telefone com uma boa usabilidade. Uma coisa que me agrada muito no telefone é o teclado qwerty físico, por que eu sempre estou conversando com alguém no Gtalk ou escrevendo algumas outras coisas, e eu tenho certeza que iria passar muita raiva com o teclado virtual (apesar de estar gostando do teclado virtual do Milestone quando está no modo horizontal). A comparação do Milestone com o Nexus One dá uma grande diferença de performance, sendo que o Nexus vence por uma boa diferença (tem processador de 1Gb e memória de 512), mas como eu já disse antes, o Milestone é um ótimo custo X benefício para quem nunca teve um Android e quer uma linha "poderosa" :D Android</h4> O Milestone em particular vem com o Android 2.1, e a Motorola promete o Froyo (Android 2.2) para o primeiro trimestre de 2011. Uma pequena lista de vantagens legais do Android: Download de aplicações legais facilmente pelo Android Market</li> Muitas aplicações de qualidade no Android Market com Rating e comentários dos próprios usuários</li> Api de desenvolvimento bem legal e multiplataforma</li> Integração fantástica com os serviços do Google, até comecei a usar alguns que eu não usava só por que é MUITO bom.</li> Multitasking de verdadinha</li> Sua liberdade continua intacta</li> </ul> Problemas</h4> Tenho visto pouquíssimos problemas no Milestone. O unico que eu vi até hoje foi um reboot do celular enquanto eu estava jogando, mas acho que eu exagerei um pouco no multitasking (para quem não sabe o Android tem um multitasking real, portanto, você precisa fechar algumas apps de vez em quando, por que elas ficam rodando em background) Considerações</h4> Eu recomendo muito comprar um Android, e o que eu recomendo atualmente no Brasil é o Milestone, por que você consegue sentir um gostinho do que o Android pode fazer sem gastar tanto assim. Para quem tem ou está pensando em ter um Android, pode aproveitar para dar uma lida na lista de aplicações legais</a> que eu estou mantendo com uns amigos. E Aguardem mais posts meus sobre Android ;) Rework Unknown — Fri, 06 Aug 2010 00:00:00 +0000 Hoje terminei de ler o livro da 37signals chamado Rework! E vou falar um pouco sobre a idéia dele aqui. Atualmente eu fiz uma compra na Amazon em conjunto com uns amigos (@vinibaggio</a>, @hugobarauna</a>, @cantoniodasilva</a>), e cogitei a compra do Rework, mas depois de uma pergunta no Twitter e algumas respostas sobre a idéia do livro eu resolvi não comprar, pois parecia muito gerencial, e acabei optando por outros (Design Patterns In Ruby, Ruby Programming Language, The Pragmatic Programmer), que falarei em outros posts :P. No fim das contas o @rafaelrosafu</a> viu minha pergunta no Twitter e me emprestou o livro! \o/ Aproveitei que eu tinha acabado de ler o ultimo livro que eu estava lendo (Mestre Gil de Ham do J.R.R Tolkien), e já iniciei a nova leitura. O livro me surpreendeu bastante, talvez por que eu estava esperando algo mais monótono, e ele é bem o contrário disso, dá várias dicas interessantes (que ajudaram eles quando estavam contruindo seus produtos, e ajudam até hoje) para quem pretende começar um novo negócio, e ainda dá algumas análises interessantes sobre como pensar como uma pequena empresa. Alguns tópicos interessantes do livro: Reuniões são tóxicas - O tempo que você perde em uma reunião e o retorno que ela te traz</li> Não contratar Rockstars - Criar um ambiente ótimo para extrair o Rockstar das pessoas</li> Planejar é chutar - Não levar tão a sério o planejamento pois todo planejamento é um chute grande ou pequeno</li> Tempo não é desculpa - Sabe aquele seu projeto que você está postergando há meses? Pois é...Você pode dedicar uma hora por dia para ele, e não esperar que aquele tempo sobrando venha, por que dificilmente virá. (esse bateu de frente comigo :P)</li> Comece no epicentro e ignore os detalhes - Mantenha o foco no centro do que o seu produto pretende fazer e evite detalhes no começo, para ter uma idéia mais geral e deixe o foco nos detalhes para uma segunda fase.</li> Durma - Não adianta trabalhar várias noites e perder toda a sua concentração e idéias por estar com uma mente cansada. Trabalhe e durma o suficiente para se manter criativo.</li> Diga não por padrão - Vejo muita gente que não sabe fazer isso, e realmente, o não muitas vezes é mais importante que o sim.</li> Faça pequenas decisões - É sempre mais fácil do que as grandes.</li> Aprenda a contratar - Contrate quando precisar, não examine apenas currículo por que ele não diz nada, não se preocupe muito com anos de experiência por que isso não é uma boa medida e não se preocupe com a localidade dos seus funcionários.</li> De liberdade aos seus funcionários - Eles não são crianças, e o seu custo de ficar monitorando eles para ver se eles estão realmente trabalhando é pior do que deixar eles por conta própria, e algum divertimento controlado no horário de trabalho não vai lhe trazer grandes prejuízos.</li> </ul> Enfim, esses são apenas alguns comentários sobre tópicos que eu achei interessante de ler no livro. É claro que eles estão falando de como é a realidade deles na 37signals, e você não vai conseguir aplicar essa idéia em qualquer empresa de qualquer área, mas para a minha realidade (e de muitos outros desenvolvedores) veio bem a calhar. O livro contém muitos outros tópicos interessantes, e tem uma leitura bem agradável (é pequeno, tem uns desenhos por capítulo, demorei cerca de 5 horas para ler ele completo). Recomendo! ;) FISL11 Unknown — Sun, 01 Aug 2010 00:00:00 +0000 Finalmente depois de 4 anos planejando eu consegui ir para o FISL! :) Para quem ainda não sabe, eu estou trabalhando na Locaweb</a> desde o começo deste mês e consegui ir com a equipe deles para o FISL. Esperava um conteúdo técnico melhor no FISL, e algumas palestras (ou a falta de boas palestras) me decepcionou um pouco, mas pelo que eu fiquei sabendo foi decisão do público os temas, então ficou meio incontrolável. Mas como eu sempre digo, a melhor coisa dos eventos não são apenas as palestras, mas também as pessoas que você conhece e os papos que rolam entre uma palestra e outra, e isso foi bem legal! :) Algumas palestras que eu assisti: Xen Ferramenta de administração da Conab</h4> Foi um case interessante do pessoal da Conab que criou uma ferramenta para administrar as maquinas Xen que eles tem internamente. E é uma aplicação Django Open Source. :) An Introduction to Qt: The toolkit that can take you anywhere</h4> Quem me segue no Twitter há algum tempo deve lembrar de alguns posts que eu fiz falando de Qt, pois eu resolvi estudar Qt e GTK Just for fun, e no fim das contas eu gostei bastante de Qt (e quase nada de GTK :P). Nessa palestra vi algumas coisas introdutórias de Qt e descobri uma IDE para Qt (no estilo .NET mesmo de ficar arrastando coisas), que é a QTCreator e uma biblioteca de teste para coisas Qt, que é a QTestLib. Libvirt: A biblioteca de virtualização</h4> Palestra do meu amigo Eduardo Otubo</a>, mas foi bem curtinha e eu só peguei o finalzinho. Como diria ele: “Não tem muito o que falar de LibVirt também”. Crash course on Git</h4> Palestra com o Scott Schacon do Github</a>, que mostrou algumas coisas simples de Git, mas foi interessante assistir mesmo assim. Nos outros dias teve outras dele falando sobre branchs e como trabalhar com eles, que foi um pouco mais interessante, mas nada além do que eu já estava acostumado. DeltaCloud: Many cloud one API</h4> Outra palestra do Eduardo Otubo, que desta vez até fez uma citação para a Locaweb</a> que talvez usará algo com DeltaCloud. Essa tecnologia é bem legal por centralizar várias APIs em um ponto único. :) Segurança e desafios em cloud computing</h4> Achei que essa palestra fosse mais sobre “como fazer cloud computing” mas nesse caso era mais “como usar cloud computing de maneira segura”, portanto não aproveitei muito a palestra. Curso de Ruby e Rails</h4> Durante o FISL teve 3 aulas do Daniel Lopes sobre Ruby/Rails. A primeira foi somente sobre Ruby puro e eu gostei bastante de ver ele passando o básico para a galera! Sinto falta de pessoas ensinando Ruby e não ensinando Rails…Por isso gostei bastante e acho que ele se saiu muito bem. Nos outros 2 dias foi algo mais Rails básico, portanto assisti pouca coisa. Mas valeu a pena para quem não conhecia, ou conhecia bem pouco a linguagem e o framework. Analise de tráfego em redesw TCP/IP com tcpdump</h4> Gostei muito dessa palestra! Foi bem conceitual sobre os pacotes e protocolos, mas teve algumas amostragem do que estava acontecendo usando tcpdump, e foi uma maravilhosa aula de redes em 1 hora. :) Lapidando Ruby – Estudo de boas práticas</h4> Eu já conhecia o palestrante (Maurício Szabo</a>) de nome pelo Guru-SP e por outros lugares que eu já tinha visto esse nome (não me lembro bem onde). A palestra foi bem interessante, e o assunto se direcionou sobre umas opiniões do palestrante sobre determinadas coisas, como padrões, refactoring, testes e outras coisas. Concordo com muita coisa que ele disse e discordo de outras, mas esse era mesmo o intuito dele com a palestra, levantar questões sobre as coisas que ele considera boas práticas e ver as opiniões da galera. Gostei bastante da palestra. Introdução a Go</h4> Essa palestra me decepcionou bastante, assim como a linguagem em si. Não vi vantagens pelas quais eu poderia apostar na linguagem Go. :( Ext4 – A nova geração dos Filesystems</h4> Está entre uma das melhores palestras do FISL na minha opinião. Foi bem técnica e mostrou quais são as vantagens do EXT4 sobre os outros FILESYSTEMS focando bastante no EXT3. As vantagens do EXT4 são bem legais, entre elas o melhor tratamento sobre arquivos grandes, e algumas soluções de problemas com datas e etc. Gostei de entender a diferença dos dois. Disponibilidade >= 99.999%</h4> Uma palestra bem para Sysadmin, mostrando como eles fazem para sempre manter a disponibilidade das aplicações dele na empresa que ele trabalha atualmente. Gostei das práticas que eles usam de sempre fazer um snapshot da maquina de produção para poder fazer a homologação em uma maquina “espelho”, mas achei meio estranho o modo de gerenciar as configurações por pacotes, sendo que usar um configuration manager faria bem mais sentido. Criando soluções inteligentes com Shellscript</h4> Esperava bem mais dessa palestra e nem terminei de assistir inteira. Esperava que o palestrante mostrasse várias técnicas de Shellscript, mas na verdade ele estava mostrando um pequeno conjunto de scripts que faziam configurações e resolvi um problema que ele tinha. Mas para mim não era nada interessante a palestra. oVirt – Ambiente minimalista de virtualização para servidores</h4> A ultima palestra do FISL para mim. Fui mesmo para conhecer o oVirt</a> e saber “qual é a dele”, mas o projeto não me impressionou muito. No fim de cada dia do evento eu sai com uma galera diferente para bater papo, um dia com o próprio pessoal da Locaweb</a>, outro com a galera do GUS-BR</a>, e outras pessoas também! Conclusão</h4> O evento foi muito legal, conheci muita gente legal, assisti palestras boas, cresci bastante e estou pronto para o próximo. Encontrei vários Rubyistas</a> por lá (faltou apenas o Carlos Eduardo da e-Genial</a> que tambem estava por lá mas não saiu na foto), inclusive a galera do Guru-RS que eu só conhecia por e-mail. Galera gente fina! Encontrei a Letícia Figueira</a> que eu já conheço há mais de 3 anos pela internet (via Rubylearning.org</a>), pois ela também era uma Assist. Teacher quando eu participava mais ativamente, e nunca tinha conversado pessoalmente. Foi bem divertido. :) E via Letícia eu acabei conhecendo a galera da Fande</a>(que é uma empresa</a> que atualmente trabalha com Ruby/Rails no RS), que são todos gente fina! Fora outros amigos que encontrei aleatóriamente, como o Clauber Halic</a> da MozBr</a>, a Bruna Griebeler</a>, o Gustavo Guanabara</a>, Fabio Akita</a> e outros. Para quem quiser ver as fotos que eu tirei por lá é só ver no meu picasa</a>. ;) Obrigado Locaweb</a> por ter me levado lá! You Rock! Review of The Silmarillion Unknown — Wed, 07 Jul 2010 00:00:00 +0000 Book: The Silmarilion</a> by J.R.R. Tolkien. Rating: ⭐️⭐️⭐️⭐️⭐️. This is J.R.R. Tolkien's life work. The other known books a product of this. He was not able to finish this masterpiece, but Christopher Tolkien finished his father's work in a great way. I'm not going to lie, the Silmarilion is not an easy to read book. I would not recommend it to anyone who was not totally aware of the other books and still looking for more middle earth content. If you already read the other books and still want to know more about middle-earth, this book is a delight. The attention to the details and the amount of backstories created for every character or entity is just amazing. It's great to see the big amount of references coming from Catholicism, Nordic stories, Greek goods (in a way), and Tolkien's imagination. If you're planning to read The Children of Húrin, do it first and skip the same story from the Silmarilion. They are the same, but it's complete in its own book (I totally recommend the story BTW). In summary, if you like Tolkien and the Middle earth, the Silmarilion is a must read to fully comprehend the background story. Serviços legais de Março Unknown — Thu, 01 Apr 2010 00:00:00 +0000 Como vocês puderam perceber (ou não) eu não postei sobre os serviços legais de fevereiro e tenho um bom motivo para isso: Não achei nenhum serviço que valia a pena ser mencionado e não queria fazer um post enchendo linguiça! :P O meu ultimo post foi sobre o Yahoo Open Hack 2009, e lá eu pude conhecer muita coisa legal, e ver outras nascendo de projetos lá mesmo! Por isso tenho informações legais para essa série novamente! ;) Vamos lá: YQL</h4> O YQL</a>, é um serviço do yahoo que ajuda o desenvolvedor que quer trabalhar com dados de vários lugares a não sei preocupar em aprender cada uma das API's. O que o YQL faz é dar para o desenvolvedor uma linguagem muito parecida com SQL (um pouco mais limitada, mas lembra muito) para que o desenvolvedor possa fazer querys das informações que ele deseja de vários serviços. Grande parte dos serviços do Yahoo estão disponíveis utilizando YQL e você pode fazer vários testes utilizando o próprio console do YQL</a>. Uma coisa legal é a posibilidade de criar algumas tabelas baseadas em dados de outros serviços, ou baseadas em .csv e outras coisas. Enfim, vale muito a pena dar uma olhada. Spaia.me</h4> O spaia.me</a> é um serviço bem legal para gerar widgets para seu site/blog. Ele faz buscas em serviços como o Twitter, Flickr, Del.icio.us e meme e traz os resultados referentes a sua palavra em um box "animado" por JQuery. Esse gerador de widgets foi feito pelo Nuxlli</a> e pelo Cipriani</a> no Open Hack day! :) Foursquare</h4> O Foursquare</a> é um serviço bem interessante para você postar sobre sua localização e fazer reviews dos lugares que você frequenta. Resolvi comentar sobre ele justamente por que comentaram comigo sobre ele no #brhackday e eu fui dar uma olhada na API, e vi os hacks legais que dá para fazer com isso. :) JSFiddle</h4> O JSFiddle</a> é um lugar muito legal para testar Javascript. Ele te dá acesso a uma série de bibliotecas javascript (tais como JQuery, Prototype, Mootools e outras) para que você possa fazer testes e comparações de funcionalidade entre uma e outra utilizando o mesmo HTML / CSS. Aconselho muito o uso dela, principalmente se você está estudando uma biblioteca específica ou apenas quer saber se determinada biblioteca tem funcionalidades melhores do que a sua biblioteca preferida. É isso ae galera! Espero que esses serviços sejam úteis para vocês! :) Yahoo Open Hack 2010 Unknown — Mon, 29 Mar 2010 00:00:00 +0000 Para quem ainda não soube, no final de semana passado rolou o Yahoo Open Hack Day 2010! O intuito do evento é juntar uma grande quantidade de Hackers para criar serviços úteis utilizando informações públicas e de preferência utilizar as API's do Yahoo (havia premios para alguns hacks com elas). Uma das coisas legais do evento é que nada é proibido com relação aos Hacks, ou seja, você pode fazer um Hack com as ferramentas do Google (não vai concorrer aos premios, mas poderá apresentar lá e tudo mais), todas as linguagens de programação estão permitidas, não somente hacks web eram permitidos, o que deixou a criatividade ir longe. :D Equipe e idéia</h4> Participei do evento juntamente com uma equipe que formamos no Ikwa</a>, e chamamos a equipe de SleepyProgrammers. Nossa idéia era fazer um site para marcar rolês fotográficos, e utilizaríamos para isso as API's do Flickr, Meme, Weather e Maps. Ao chegar no evento e ver a palestra sobre YQL nós já percebemos que não seria necessário aprender a usar essas várias API's e apenas precisávamos aprender a usar o YQL e saber quais informações poderíamos retornar de qual serviço. :) Metodologia e projeto</h4> </a> Como já estamos acostumados a utilizar Scrum no Ikwa</a> nós resolvemos fazer o mesmo para o nosso projetinho. Começamos com uma planning meeting logo na primeira hora para poder dar uma estimada no que pretendíamos fazer, e logo depois dividir as tarefas entre os membros da equipe. Mais ou menos de 2 em 2 horas (ou um pouco mais) fazíamos umas stand-up meetings para manter todos atualizados. A noite percebemos que isso não estava sendo muito necessário por que estávamos em constante comunicação, mas mesmo assim resolvemos seguir o costume, afinal demorava apenas uns 4 minutos. :) O projeto seguia bem, com layout legal e algumas buscas supostamente funcionando até mais ou menos as 9 da noite. Os problemas</h4> Já percebemos que a nossa busca não estava retornando exatamente o que gostaríamos de receber, mas deixamos para dar uma refinada nisso no final do tempo, para não ficar muito tempo presos nisso.</li> Tivemos um programador a menos (@_bojak</a>) que infelizmente estava usando Windows (acreditem se quiser) por que o netbook que ele comprou (exatamente para evitar ter que usar windows no notebook velho que ele tinha) não chegou a tempo do evento. Muitas das coisas que são simples de se instalar/fazer em um "Unix like" são uma grande dor de cabeça para se fazer no Windows, portanto o @_bojak teve tantos problemas que chegou uma hora que desistiu de colocar a mão em código.</li> Algum descuidado da equipe criou a pasta "Views" no famigerado Textmate (escrevi uma gracinha aqui e apaguei para não gerar flame de textmate), e assim bugou a aplicação na minha maquina Linux, e me deixou um tempinho procurando qual era o problema. #fail</li> O Heroku não colaborou para funcionar utilizando o bundler, e depois de muito tempo tentando nós abandonamos o bundler e utilizamos oldstyle mesmo.</li> O nosso outro programador (@jorge_silveira</a>) saiu (já tinha avisado que sairia) dizendo que voltaria e simplesmente deixou a equipe na mão (tem seus argumentos, mas essa é minha opinião...)</li> </ul> O fail do projeto</h4> Depois desse monte de problemas eu já estava desmotivado com o projeto e comecei a ficar com bastante sono, portanto tirei umas 3 horas para dormir (fora o tempo que dormi na mesa), enquanto só o @_bojak</a> ficou trabalhando motivadão (usando o computador do @rafaeltimbo</a> que tambem estava dormindo :P). Logo pela manhã sabendo que um programador tinha arregado (@jorge_silveira</a>), um estava impossibilitado de trabalhar com seu próprio computador (@_bojak</a>) e nossa busca não estava retornando coisas legais para continuar, nós decidimos que esse projeto ficaria para depois do Open Hack Day. No fim das contas fizemos uma retrospectiva bem legal, onde vimos grande parte dos problemas que tivemos e boa parte das soluções tambem, foi bem legal! :) O evento</h4> Ok, nosso projeto não vingou mesmo, mas o evento valeu muito para mim! Aprendi coisas novas, revi amigos, conheci pessoas novas, conheci as API's do Yahoo, comi e bebi de graça, descobri que não devo acreditar nas palavras de alguns, descobri que algumas pessoas com certeza estarão na minha equipe novamente se quiserem.... E mais várias outras coisas! No fim das contas eu tenho uma coisa para recomendar para quem não foi... Quando tiver o próximo, não perca a oportunidade! O evento vale muito a pena! :) Para quem quiser ver as fotos que eu tirei no evento pode dar uma olhada no meu album do Picasa</a>. Linux, Vim, Screen e Pair programming! Unknown — Mon, 29 Mar 2010 00:00:00 +0000 Aqui estou eu mais uma vez para falar mais uma das maluquices que eu fiz um bom tempo atrás mas não tive tempo de postar. Primeiramente eu vou falar o que muita gente já falou muito bem, que é sobre screen e pair programming. Mas vou dizer como funcionou para mim. Alguns posts que eu li antes e depois de começar a brincar com screen e pair programming, e que eu gostei: Post do Caike sobre Pair programming remoto usando screen</a></li> Post do Qmx sobre pair programming usando screen</a></li> </ul> Primeiramente vamos começar com umas dicas do post do caike: Para mim foi necessário alterar as permissões do Screen: sudo chmod +s /usr/bin/screen sudo chmod 775 /var/run/screen</code></pre> Agora é só seguir a velha receita dos dois posts: Primeiro usuário: O primeiro usuário acessa o computador host via ssh</li> executa o comando screen -S nomedoscreen</li> </ul> Segundo usuário: Acessa o servidor com o mesmo nome de usuário/senha do primeiro</li> executa screen -x</li> </ul> Pronto! As duas pessoas estão compartilhando a mesma tela agora e podem usar o Vim para programar (claro, qual outro editor seria, não!?). Nunca consegui utilizar o screen multiusuário (como mencionado no post do caike) mas isso não é um grande problema. :) Como eu usei</h4> Primeiramente fiz um pair programming normal com o @mateuslinhares</a>, onde nós dois ficavamos no mesmo screen conversando (estavamos há menos de 2 metros de distância), e cada um com seu teclado, podendo intervir a qualquer momento. Isso foi legal por que não precisávamos ficar dividindo espaço de um mesmo monitor ou de um mesmo teclado, e ainda driblava outros problemas que tínhamos na época. Uma nova idéia</h4> Na época desse pair programming estavamos com uma task grande e trabalhosa, mas podia ser feita individualmente, e provavelmente seria mais produtiva do que em pair programming, mas tinha uma particularidade muito interessante. Cada um de nós conhecia melhor uma parte do sistema, portanto, se mantivessemos contato contínuo isso ia acelerar o trabalho, pois precisávamos alterar/retirar algumas coisas que podiam ou não ser importantes para o sistema como um todo. Levando tudo isso em conta me surgiu uma idéia: Por que não fazer tudo com um “semi pair programming”, onde cada um trabalhava no seu computador mas visualizando a tela do outro em um split. </blockquote> Tanto eu como o @mateuslinhares estamos acostumados a separar o nosso vim em vários splits verticais e horizontais, ou seja, um split vertical do screen não seria o problema. O que fizemos</h4> Decidimos então seguir o seguinte script: Setup das duas maquinas: Vim</li> Screen</li> Um usuário em comum</li> </ul> PotHix :</h5> com o usuário compartilhado executa um screen -S pothix na sua maquina</li> Abre um novo split no screen com o comando ctrl+a s</li> Nesse novo split acessa a maquina do Mateus e executa screen -x para acessar o screen que o @mateuslinhares criou na maquina dele</li> Volta para o split anterior e trabalha normalmente</li> </ul> @mateuslinhares</h5> com o usuário compartilhado executa um screen -S mateuslinhares na sua maquina</li> Abre um novo split no screen com o comando ctrl+a s</li> Nesse novo split acessa a maquina do Mateus e executa screen -x para acessar o screen que o PotHix criou na maquina dele</li> Volta para o split anterior e trabalha normalmente</li> </ul> Seguindo esse script teremos os 2 utilizando um screen com um split, sendo que um split é para seu trabalho local e no outro você pode acompanhar e dar pitacos no trabalho do seu comparsa! :) Benefícios</h4> No caso dessa nossa task isso resolveu muito o nosso problema, por que conseguimos trabalhar em locais distintos mas sempre em constante comunicação, o que sempre trazia alguns comentários como: PotHix: Ow… Não tira isso aí não por que vai quebrar tal parada. ou então: Mateuslinhares: Cara… Olha isso aqui no screen, dá para fazer na sua parte tambem. Conclusão</h4> Para mim foi muito bom e recomendo a todos para tentarem algo do tipo quando tiverem chance (a não ser que você use Textmate…nesse caso…boa sorte! :P)! A unica coisa que eu recomendo é utilizar 2 monitores, assim você pode deixar a tela do seu comparsa no outro monitor (divida os monitores verticalmente) e trabalhar com vários splits no seu monitor. :) É totalmente possível trabalhar com 1 monitor apenas (foi assim que trabalhamos) mas você obviamente perde um pouco de espaço. Espero que essas informações sejam úteis para mais alguém. Qualquer dúvida ou sugestão deixe nos comentários. :) Palestra sobre Vim Unknown — Mon, 29 Mar 2010 00:00:00 +0000 Esse vai ser um post curto, apenas para deixar registrado algumas informações sobre a palestra de Vim que teve no sétimo encontro do Guru-sp (sim, eu fui o palestrante :D). Primeiramente, já começo com uma desculpa, por que já faz mais de 2 semanas que palestrei e só agora estou fazendo esse post. :( Foi bem legal palestrar para uma galera que já conhecia ao menos um pouco do editor. Quando eu estava planejando o que eu ia falar eu fiquei com uma grande dúvida de qual seria a minha linha de apresentação, por que eu não sabia quantos já conheciam o editor, portanto eu poderia chegar falando de coisas avançadas e ninguem entenderia nada, ou pelo contrário, se muitos conhecessem e eu chegasse falando de coisas básicas demais a palestra seria um saco. A minha solução para isso foi preparar os slides de uma forma que eu conseguisse falar mais ou menos de determinados assuntos baseado no conhecimento do pessoal. Os slides que saíram foram esses: </iframe> Quando perguntei para o pessoal quem já utilizava, quem nunca abriu (ou não conseguiu sair...heheh) e que usa como editor principal, eu descobri que estava equilibrado. Portanto segui uma linha mais comum. Tive a sorte do agaelebe</a> gravar (valeu Hugo!), e portanto temos o vídeo tambem: </iframe> Qualquer dúvida, comentário ou sugestão é só postar aqui! :) Campus Party 2010 Unknown — Tue, 02 Feb 2010 00:00:00 +0000 Esse começo de ano eu estou aproveitando para participar de alguns eventos, e a Campus Party é um dos principais deles. Assim que eu entrei na empresa que eu estou trabalhando atualmente eu já informei que em janeiro tinha um evento que eu gostaria muito de participar (entrei na empresa em abril :P) e deixei combinado que eu estaria liberado para o tal, portanto agora consegui uma semana de férias para aproveitar a campus party! :) Entrada</h4> Começando pela entrada no evento na segunda feira. Entrar em um evento onde se está esperando 6000 pessoas que vão receber barracas para acampar e tem que ter seus notebooks cadastrados e etiquetados nunca é fácil, e não foi dessa vez que as coisas foram mais rápidas. Na segunda feira tínhamos uma fila monumental para cada coisa que tinha que fazer, desde a entrada, passando pelo cadastramento e pelo local onde retiramos as mochilas e barracas. Mas não estava mal organizado a princípio, o problema era a quantidade de gente mesmo. :) Camping</h4> A área de camping estava organizada como sempre, mas dessa vez todas as barracas estavam montadas (da ultima vez nós tivemos que montar as nossas) e eles estavam apenas distribuindo os numeros delas. Levei um coxão inflável dessa vez por que o coxão do ano passado era quase um lençol...hehehe...Era como se eu estivesse dormindo no chão. Para dormir por lá é sempre barulhento pois a Campus Party não para um segundo, sempre tem pessoas gritando sem motivo independente da hora, mas isso não atrapalha (muito) a diversão. Palestras</h4> Achei que fosse assistir bem mais palestras esse ano, mas quando estava por lá eu fiquei com preguiça de assistir algumas. :P Uma das coisas que foi mais legal na Campus Party esse ano na minha opinião foi a transmissão ao vivo das palestras! Eu mesmo assisti mais de uma palestra pela internet, tanto quando eu estava em casa como quando eu estava no evento, por que eu achava o audio bem melhor do que ter que ouvir no meio de todo o ruído que os campuseiros produzem. Gostaria de destacar algumas palestras que eu assisti e gostei muito: Matemática para não matemáticos</li> Matemática orientada a Computação gráfica</li> Criando e lançando um site em 42 minutos com Sinatra</li> Segurança e RubyOnRails</li> Introdução ao Blender</li> Desenvolvimento de games para IPhone</li> </ul> Cada uma teve suas particularidades, mas foram bem legais de se assistir e cada uma agregou um pouco a meu conhecimento. Internet</h4> A internet do Evento não deixou a desejar, e como muitos sabem, o forte de compartilhamento da Campus Party não é a internet, e sim os programas de P2P que usamos internamente (no caso o dc++). Alguns pontos de rede não estavam funcionando, mas esse não foi um grande empecilho, sendo que a grande maioria estava e você podia simplesmente sentar, plugar o seu notebook e compartilhar arquivos a mais de 1MB por segundo (consegui 9MB no começo do evento). A internet para download externo também não deixou na mão, possibilitando downloads a 1MB por segundo dependendo do servidor que está fornecendo o download, Inovação</h4> Um foco bem legal da Campus Party é trazer inovação, mostrar projetos inovadores, incentivar jovens a inovarem criando novas tecnologias e novos negócios. Na área expo tinha muitas coisas interessantes, como por exemplo, um jogo que utiliza o controle do Wii e simula um spray que deixa você "pixar" uma tela virtual e fazer vários tipos de desenhos. Networking</h4> Essa é a parte que mais me motiva a ir para a Campus Party! Muito mais do que arquivos, internet, palestras ou outras coisas, eu vou para a Campus Party para ver os amigos e bater um papo sobre coisas interessantes/ Até amigos de outros estados vem para a Campus Party e eu tenho a chance de vê-los, né Griebeler</a>! :) E tudo isso sem contar os amigos novos que eu faço por lá e o pessoal que eu só conhecia pela internet e conheci pessoalmente! Entre eles estão Ricardo, Pedro, Lucas, Rencka, João, oTubo e mais uma galera! :) Conclusão</h4> Eu recomendo participar da Campus Party pelo menos algum dia se você tiver a chance. :) Você já deve ter ouvido falar que a Campus Party é mó zona, fica um monte de gente gritando sem motivo, pessoas fazendo brincadeiras que não tem graça nenhuma, as palestras são difíceis de ouvir tanto pela zona como por que há várias palestras simultâneas e os palcos são próximos e etc... Eu só tenho uma coisa a te dizer: Isso é tudo verdade, mas eu iria mesmo assim! Nada disso atrapalha a sua diversão, e o seu benefício, você apenas precisa "entrar na brincadeira" e aproveitar. ;) Show do Metallica Unknown — Tue, 02 Feb 2010 00:00:00 +0000 E vou para um assunto meio OFF no meu blog (ou não), que é falar de shows que vou, nesse caso o do Metallica! Há muito tempo queria que o Metallica viesse para o Brasil, e no ano passado que tiveram vários shows bons (ACDC, Motorhead, Megadeth, Iron Maiden e etc) fiquei sabendo que eles viriam ao Brasil e já antecipei a compra do ingresso com a ajuda do meu amigo Bruno Assis</a> que é cliente do CityBank. Em semana de Campus Party já me preparei para ir para o show, mas o cabeção aqui esqueceu a carteirinha de estudante em casa na carteira (levo só o essencial para o show, mas esqueci a carteririnha :P) em casa, portanto tive que apelar para o meu pai me encontrar em algum lugar com a minha carteira, o que gerou grandes problemas entre me perder pelos lados do morumbi de moto e outras coisas. Relevando todos esses imprevistos, consegui chegar novamente ao estádio e entrar. Combinei com um amigo da faculdade que encontraria ele lá dentro, mas chegando na pista e vendo aquela multidão de pessoas já tinha me conformado qeu ele nunca ia me encontrar por lá. Por incrível que pareça, quando o show do Sepultura estava começando lá estava o meu colega me encontrando. Show do Sepultura</h4> Uma coisa muito legal desse show é que o Sepultura ia abrir o show, ou seja, alem de ver Metallica ainda ia ver Sepultura antes e ter a chance de participar de umas rodas pesadas por lá! :P Infelizmente conheço pouco de Sepultura, até gosto das musicas, mas não conheço as letras das musicas e tal, portanto ainda fiquei viajando um pouco ate tocar Territory! :D O Show foi muito legal, apesar do som estar meio baixo e tal. Show do Metallica</h4> Depois do show do Sepultura teve um tempo de uns 40 minutos e o Metallica finalmente abriu o show com Creeping Death! Que realmente é coisa linda de se ouvir ao vivo! :D O show teve um monte de musicas que eu sempre quis ouvir ao vivo e felizmente eu estava lá, gritando, pulando, me batendo...Enfim, me divertindo em momentos memoráveis. :) As musicas que do set list foram: Creeping Death</li> For Whom The Bell Tolls</li> The Four Horsemen</li> Harvester Of Sorrow</li> Fade To Black</li> That Was Just Your Life</li> The End Of The Line</li> The Day That Never Comes</li> Sad But True</li> Broken, Beat and Scarred</li> One</li> Master Of Puppets</li> Blackened</li> Nothing Else Matters</li> Enter Sandman</li> Stone Cold Crazy</li> Motorbreath</li> Seek and Destroy</li> </ul> Como você pode ver, só musicão! Valeu meu ingresso, apesar de eu ter olhado o set list do segundo show e ter achado melhor que o primeiro ainda! :D Se quiser ver as poucas fotos que eu tirei (4 ou 5 sem graça nenhuma, só pela muvuca mesmo) veja no meu picasa</a>. Organização e Saída</h4> Ao contrário do show do Iron esse show foi muito bem organizado (shows em estádios são sempre melhores) e consegui entrar e sair do estádio facilmente. Não tenho nada a reclamar do evento. A minha experiência em shows no Morumbi (ACDC e Metallica) dizem que se tiver show por lá você pode ir tranquilo sabendo que provavelmente vai encontrar uma boa organização e maneiras fáceis de entrar e sair. Conclusão</h4> É claro que para ir em um show desse tamanho você precisa ignorar por algumas horas todos os sentidos: Visão - Vai ser destruída pelas luzes do estádio</li> Audição - Só vai voltar ao normal no outro dia :P</li> Olfato - Cerveja, maconha, suor, cigarro...Você precisa ignorar tudo isso que está ao seu redor (fazer o que...)</li> Tato - Muita gente sem camisa suado passando do seu lado, e fora o calor</li> Paladar - A sede mata qualquer um, e eu morro de sede mas não compro um copinho de água por 5 reais.</li> </ul> Mas no fim das contas eu só tenho uma coisa a dizer: Se tiver a chance de ir...Vá! :D Serviços legais de Janeiro Unknown — Tue, 26 Jan 2010 00:00:00 +0000 E ae galera! Vamos para mais um post sobre os serviços legais do mes. OpenDNS</h4> Estranho eu falar de OpenDNS</a> não? Já existe faz tanto tempo e muita gente já conhece/usa. O que me fez colocar ele na lista de serviços legais foi justamente as opções que você tem na web do OpenDNS! Se você se cadastrar no OpenDNS você pode configurar muitas coisas legais, como por exemplo a página de endereço não encontrado, ou a página de tentativa de fishing, entre outras. Além de configurar essas páginas você pode tambem definir atalhos, para quando você tentar acessar algo como: "http://pothix" ele já redirecionar para "http://pothix.com/blog" por exemplo. :) Heroku</h4> O Heroku</a> é bem conhecido pela comunidade Ruby, pois é uma das maneiras mais fáceis de se fazer deploy de uma aplicação simples, bastando poucos comandos para que sua aplicação já fique disponível na web como um subdomínio do Heroku! Só para dar uma idéia da simplicidade, o que você precisa fazer para mandar sua aplicação para o heroku (estou assumindo que vc usa Git): sudo gem install heroku</code></li> heroku keys:add path/para/sua/key</code></li> heroku create nome_do_proj</code></li> git push heroku master</code></li> </ul> E pronto! Sua aplicação já estará disponível em http://nome_do_proj.heroku.com</a> Caliper</h4> O Caliper</a> é um serviço web bem interessante para se obter métricas do seu código. Uma das coisas que eu mais gostei no Caliper é que ele não exige cadastro para uso, você pode apenas colocar a URL do seu projeto Git e ele já gera os relatórios utilizando a gem metric_fu e mantém um link para acesso dos mesmos. Como de costume os meus posts sobre os serviços legais do mes são curtos, portanto, eu fico por aqui! Espero que sejam úteis! ;) A cabeça de Steve Jobs Unknown — Tue, 05 Jan 2010 00:00:00 +0000 Aqui estou eu novamente para falar de um livro que eu li nas férias! Dessa vez vou comentar sobre: "A cabeça de Steve Jobs" Sobre o livro</h4> O livro é bem interessante e conta como Steve Jobs fez para ter o sucesso que tem atualmente, contando não somente os acertos, mas também os erros de Steve com o mercado, o que faz com que você caia na real que ele (assim como você) é apenas uma pessoa comum e que as vezes suas decisões fantásticas levavam a uma má situação. Steve Jobs</h4> Como todos que me conhecem sabem, eu estou longe de ser um Apple fan, mas mesmo assim tive vontade de ler esse livro para ver se realmente Steve Jobs é tudo o que dizem. A experiência do livro mostra um Steve bem rude com seus funcionários, mas que fazia as coisas andarem corretamente dentro da empresa. Pelo visto ele tinha as boas partes de vários lados, pois ele tinha aquela grande vontade de mudar o mundo e além disso era teimoso e estava disposto a apostar pesado em seus produtos independentemente do quanto ele ia ter que arriscar para isso. Achei muito interessante o modo como ele revolucionou a Apple focando em poucos produtos, mas produtos de qualidades dos quais eles dominavam por completo. Outra coisa que eu achei legal da personalidade dele é o perfeccionismo, o que ajuda a criar ótimos produtos, coisas que foram pensadas minunciosamente para estar da melhor forma possível, e isso não está presente em todos os lugares, atualmente o que vemos pelo mercado são vários produtos que foram pensados para funcionarem bem, e não para atenderem todas as necessidades ou durarem muito. Elitismo! Isso é uma coisa que eu acho bem importante por sinal, Steve sempre estava buscando pelos melhores, pessoas que ele sabia que fariam o que seria de melhor para o que ele estava desenvolvendo, e não se importava com a quantidade de dinheiro que precisaria para ter essa pessoa (ou até mesmo esse objeto, ele também fazia isso com locais e objetos, sempre o melhor!) em seus projetos. Prós do livro</h4> Achei bem legal as fontes de todas as frases que estão no livro, o que comprova cada uma das entrevistas que o autor fez com as pessoas que estavam próximas de Steve Jobs nesse meio tempo. Falar sobre o sucesso de Steve Jobs em suas duas outras empresas (Pixar e NeXT) e o quanto elas influenciaram na vida da própria Apple. Contras do livro</h4> Você fica totalmente perdido no tempo quando está lendo. O livro não foca em uma ordem cronológica, portanto hora você está vendo uma citação de 1997 e logo depois uma de 2002, e no próximo capítulo uma de 2000. Conclusão</h4> Se você gosta de criar coisas, ou pensa em abrir uma empresa, leia esse livro e entenda uma forma muito interessante de ver como fazer produtos, erguer uma empresa ou conquistar pessoas. Esse livro com certeza já mudou um pouco a minha forma de pensar. ;) Anjos e Demônios Unknown — Mon, 28 Dec 2009 00:00:00 +0000 Felizmente eu estou de férias da faculdade novamente, e isso me dá um tempo livre para ler alguns livros, portanto resolvi começar com “Anjos e Demônios“, que é um livro que eu estou postergando a leitura faz mais de 2 anos (desde que li o código da vinci). Eu particularmente gosto dos livros do Dan Brown</a>, pois em sua grande maioria são histórias “polemicas” por misturar alguns fatos reais (que ninguem consegue provar a favor nem contra) com outros que são pura ficção. Antes de ler o “Anjos e Demônios” eu já li “O código da Vinci” e “Fortaleza Digital“, portanto já estou acostumado com o estilo de escrita do Dan Brown</a> que sempre me estimula a leitura. Pretendo (como em todo BookReview meu) novamente não dar spoilers do livro, por que senão perde toda a graça se você for ler, portanto vou dar apenas a minha opinião geral sobre o assunto. Enfim, vamos as minhas opiniões: :) Livro</h4> Achei o livro muito legal, segue a mesma ideia dos outros livros do Dan Brown</a> que eu li, ou seja, sempre com um fato marcante (morte de alguem) no começo para dar origens a vários fatos que precisam ser investigados. Uma das coisas que eu achei interessante no livro é que toda a história acontece em apenas 1 dia (diferentemente do Senhor dos anéis onde se passam dezenas de anos…hehehe ), e gerou um livro bem extenso com uma grande riqueza de detalhes. O desfecho da história desse livro (como todos os outros livros do Dan Brown</a>) é muito legal e tem sempre as grandes reviravoltas e revelações que deixam você boquiaberto e com vontade de ler mais rapidamente cada parágrafo. Mas para saber quais são você vai precisar ler. :) Filme</h4> Se você leu o Livro e gostou eu aconselho fortemente que você nem veja o filme. Eu estava totalmente curioso para ver o filme e logo quando terminei de ler o livro corri direto para assistir, e me deparei com um grande #fail. Alguns dos motivos que me fazem ter essa ideia do filme: Várias partes da história foram modificadas</li> Os nomes de alguns dos personagens mudaram</li> Personagens legais não apareceram</li> Personagens que eu nunca vi mais gordo apareceram</li> </ul> Eu até entendo o livro fugir um pouco da história, até por que, para que a adaptação seja boa a história precisa de algumas mudanças, é completamente normal, mas alterar o nome dos personagens? Isso para mim já é demais Final alternativo para fazer com que o personagem principal tenha mais prestígio para mim também foi totalmente desnecessário. Considerações finais</h4> O livro é muito interessante e eu recomendo a leitura tanto para quem já conhece as histórias do Dan Brown</a> como para quem nunca leu nenhum livro e tem curiosidade. E apenas para lembrar… NÃO veja o filme se você já leu o livro. 😉 Crontab dentro da sua aplicação rails com whenever Unknown — Wed, 02 Dec 2009 00:00:00 +0000 Hoje estou aqui para falar de uma coisa que quando vi pela primeira vez ignorei por parecer uma coisa boba, mas olhando melhor eu percebi que é uma idéia bem interessante. O que a gem whenever faz é manter o seu crontab de uma forma mais Ruby, e melhor, dentro da sua aplicação! A principio parece estranho tentar manter o crontab dentro da sua aplicação, mas ganhamos muitas vantagens com isso: versionamento</li> menos acesso ao servidor</li> rapida atualização do crontab do servidor via capistrano</li> forma mais legível de ver o crontab</li> </ul> E tudo isso não influi no crontab que você já possui ( e que muitas vezes tem muita coisa que não é relacionada com a aplicação ), pois o whenever cria uma seção que ele atualiza mantendo a seção antiga onde está. Para instalar o whenever é a mesma facilidade de sempre: sudo gem install whenever</code></pre> OBS: Lembrando que a primeira linha só é necessária uma vez, se você já tem o gemcutter no seu sources então ignore-a. Depois disso execute: wheneverize .</code></pre> O comando acima vai gerar os arquivos necessários para a utilização do whenever ( básicamente o config/schedule.rb ). E a partir de agora você já pode atualizar o seu crontab com as suas configurações feitas no config/schedule.rb executando o comando: whenever --update-crontab suaaplicacao</code></pre> Quando você passa como parametro a sua aplicação ele cria um bloco apenas para as configurações da sua aplicação no crontab. Mas é claro que você não vai precisar acessar o servidor e executar esse comando toda vez que você alterar o arquivo de schedule, para isso você provavelmente deve estar usando o capistrano para ser mais DRY. Se estiver usando inclua algumas linhas no seu deploy.rb: after "deploy:symlink", "deploy:update_crontab" namespace :deploy do desc "Update the crontab file" task :update_crontab, :roles => :db do run "cd #{release_path} && whenever --update-crontab #{application}" end end</code></pre> OBS: Se você tiver problemas no deploy com essa linha ( como se o comando whenever não existisse ), tente adicionar o path absoluto para o whenever. E com isso a cada vez que você fizer um cap server deploy seu crontab será atualizado com as configurações contidas no config/schedule.rb. Veja alguns exemplos do que pode ter no seu schedule.rb: every 4.minutes do rake "ts:in" end every 1.day, :at => '5:25 am' do rake "bla_bla" end every [:monday, :thursday], :at => '11:59 am' do command "sudo rm -rf /" # claro! end</code></pre> Nada do que eu demonstrei aqui é uma grande novidade, você pode ver mais exemplos de como usar no Railscasts</a> e na própria página do plugin</a>. Espero que seja útil para mais alguem como está sendo para mim. Dev In Sampa Unknown — Wed, 02 Dec 2009 00:00:00 +0000 </a> Nesse sábado, dia 28/11/2009 aconteceu aqui em São Paulo (obviamente! :P ) o Dev In Sampa! Um evento para desenvolvedores em geral, sem foco em uma determinada linguagem de programação, ou seja, um evento bem legal e pragmatico! :D Perdi um pouco a hora, portanto não assisti o começo da palestra do José Valim, que por sinal é um assunto que muito me interessa, portanto recorri aos vídeos do @agaelebe</a> para assistir o comecinho. Para quem quiser ver os vídeos confira no blip.tv do agaelebe</a>. Agora vamos para a programação e meus comentários: José Valim - Tópicos de machine learning: classificação de textos</h4> Como disse no começo do post, eu perdi o começo da palestra do Jose Valim por que eu me atrasei (foi por um bom motivo</a>), mas compensei depois assistindo o vídeo. A palestra foi muito boa, e abordou um dos tipos de tema que eu gosto, machine learning é bem interessante! Essa é uma das coisas que eu pretendo estudar só por diversão, por que parece ser bem legal. O @josevalim</a> fez sua tese sobre classificação de textos, portanto conhece bem do assunto e foi muito interessante ver as pesquisas dele consolidadas e simplificadas em uma apresentação. :) Rodrigo Yoshima - Design de Software: As técnicas esquecidas...</h4> O @rodrigoy</a> fez uma palestra bem legal comentando sobre várias técnicas esquecidas sobre design de software, e muitos programadores que assistiram essa palestra devem ter se visto em várias situações por ele citadas ( eu fui um deles em alguns pontos ). Algumas das coisas citadas foram: Design incremental</h5> Nunca pense naquela história de "Preciso do pedido para poder fazer a tela de cadastro" sempre comece por aquilo que agrega mais valor. Faça as coisas sempre usando um pensamento incremental, criando testes para que quando você resolva um bug não crie mais outros por não saber as consequências de suas modificações. Sempre tomar cuidado com o design incremental para que ele não se torne um problema pelo mal crescimento da sua aplicação. Tomar cuidado com arquiteturas monolíticas / egípcias - Arquiteturas difíceis de refatorar, que usam componentes pesados, quem ninguém sabe como foi feita e etc.</li> Separar a função de cada unidade, não deixando que o produto tenha que saber sobre vendas, por exemplo.</li> É melhor um design ruim com testes do que um design bom sem testes por que com testes você pode refatorar, agora sem testes a situação já muda bastante.</li> </ul> Entre outras coisas muito interessantes que eu não vou mencionar por que senão meu post vai ficar enorme, mas assista o vídeo e veja as dicas interessantes que ele dá. Primeiro Coffee break para encontrar os amigos e bater papo! Tinha bastante gente do Guru-sp por lá ( @almeidaricardo</a>, @shadow</a>, @rafaelrosafu</a>, @scalone</a>, @bbcoimbra</a>, @nelsonmhjr</a>, @_bojak</a>, @cassiomarques</a>, @dcreq</a> e mais um monte de gente! ), foi legal para bater um papo com os conhecidos. :D Só para constar, o Ronaldp Ferraz (@rferraz</a>) veio falar comigo sem crachá e sem cavanhaque, e eu obviamente não conheci, tinha que se apresentar formalmente ( ou seja, com cavanhaque! O @tinogomes</a> já aprendeu! haha ). :P Ronaldo Ferraz - Criando sua própria linguagem de programação</h4> Palestra muito boa do @rferraz</a>! :D O assunto foi bem denso, mas bem interessante, ele mostrou alguns conceitos e informações interessantes sobre como criar e brincar com a sua própria linguagem de programação de uma maneira não tão difícil usando Treetop e Ruby. Como muitos já sabem o Ronaldo tem conhecimento infinito em linguagens de programação, portanto a palestra foi bem legal com vários exemplos em várias linguagens. João S. O. Bueno - Desenvolvimento de jogos com Python</h4> Puxa vida...Essa palestra foi um grande 417 ( Código de retorno do HTTP para Expectation Failed ), por que como muitos sabem eu adoro desenvolvimento de jogos, e fiquei muito feliz por ver uma palestra desse segmento nesse evento. Outra coisa que me entusiasmou bastante foi o fato de ser com Python, que assim como Ruby é uma linguagem que eu gosto bastante, mas em outra palestra que eu tinha visto ( no CONISLI 2008 ) o palestrante não foi muito feliz com o conteúdo. Enfim, e fui com muita vontade de ver essa palestra. No início da palestra quando falaram o nome do palestrante e eu o vi, percebi que parecia familiar, e por incrível que pareça...Era o mesmo do CONISLI 2008... Mas até aí tudo bem, agora o nível do pessoal é diferente e já se passou mais de 1 ano desde a ultima palestra, ou seja, essa prometia ser bem melhor. Como puderam ver pelo começo do post, foi um grande engano meu, apesar de o palestrante falar que ia focar mais em jogos já que o pessoal já conhecia Python, ele ficou muito em Python e no finalzinho mostrou alguns joguinhos feitos em PyGame, como se a idéia da palestra fosse mostrar que Python é legal (que nós já sabemos! :D ) e dá para fazer jogos tambem. Enfim...Me decepcionou... :( Intervalo para almoço</h4> O Almoço foi meio corrido por que o evento estava meio atrasado, mas mesmo assim deu para conversar bastante com a galera do Guru-sp no shopping ( não me pergunte qual ). Guilherme Silveira e Adriano Almeida - Do REST ao RESTFul</h4> Na volta do almoço tivemos uma palestra teórica sobre REST e RESTful, que por sinal abriu muito a mente sobre o assunto. Mesmo o assunto sendo teórico o Guilherme Silveira e o Adriano passaram muito bem a idéia e souberam conduzir bem a palestra para manter o conteúdo bem dinâmico. Nando Vieira - Escrevendo testes no JavaScript Aqui um assunto que vem me interessando cada vez mais, testes! E como eu sempre gostei de Javascript, a palestra foi bem relevante. Infelizmente o Nando Vieira não conseguiu mostrar todos os exemplos que ele tinha planejado, mas foi bem interessante ver o live coding, e as amostras de testes para determinadas coisas. Gostei bastante da syntax do JSpec, não sei como fica a integração dele com o prototype ( que é o que eu estou usando atualmente no trabalho, mesmo preferindo JQuery ), mas pretendo dar uma chance para ele assim que possível. Luis Cipriani - Web em tempo real com Ruby e XMPP</h4> Bem legal o case que o Cipriani mostrou sobre a sua aplicação da maratona de basquete, achei muito interessante as ferramentas que ele usou, e vi que ele soube passar bem as informações sobre o XMPP que foram necessárias. Coffee-break</h4> Agora sim um coffee break que deu um tempinho para conversar com uma outra galerinha como o @rferraz</a>, a @narwen</a>, o @fabiokung</a> e mais outra galera. Ricardo Almeida - Buscas poderosas com Solr</h4> Estava curioso desde o ultimo post do @dcrec</a> sobre o Solr, e a palestra do Ricardo foi o ponto para tirar as minhas dúvidas. Vi muitas vantagens do Solr sobre o Sphinx e nenhuma do Sphinx sobre o Solr, acho que vale a pena tentar uma migração num futuro não tão distante. Radamés Ajna - Arduino - Computação Física</h4> A palestra do Radamés foi demais! Além do Arduino ser fantástico, o Radamés soube apresentar muito bem, mesmo com alguns problemas nos slides ele mostrou muito bem algumas coisas legais que dá para fazer com o Arduino, sempre com exemplos muito interessantes de coisas que já fizeram ou que ele pretende fazer. A interface para mexer com arduino realmente não parece ser tão complexa, e eu gostaria mesmo de ter algum conhecimento em eletronica nesses momentos, mas quem sabe algum dia eu tiro um tempinho para dar uma brincada. :D Fabio Kung - Cloud Computing. E eu com isso?</h4> Para fechar o evento tivemos uma palestra muito legal do Kung mostrando o que "ele acha" que é cloud computing, e os tipos de cloud computing que são oferecidos ( IaaS, PaaS e SaaS ). Ele mostrou como funciona e por que são usados os cloud computings atualmente, e como estão as experiencias dele com cluod computing atualmente. Achei a palestra bem legal, e é interessante ver as opiniões e experiências de alguem que realmente está vivendo essa parte de cloud computing. Conclusão</h4> O evento terminou bem atrasado ( mais de 20:00 ), mas valeu muito a pena ter ido. Há tempos estava sentindo falta de um evento que não levasse em consideração apenas uma linguagem de programação, algo que fosse mais pragmático mas que fosse totalmente voltado a desenvolvimento. Parabens a todos os organizadores do evento e espero ver vocês novamente na próxima edição! :D Serviços legais de dezembro Unknown — Wed, 02 Dec 2009 00:00:00 +0000 Infelizmente não consegui postar sobre os serviços legais do mes de novembro por que eu estava cheio de coisas para fazer ( devido as provas de fim de ano, e meu curso é anual ), portanto não consegui agregar nada para novembro, e muito menos tempo para postar. Mas agora estou eu aqui denovo para postar sobre o que eu achei de legal na internet nesse meio tempo! E lá vamos nós: Mocking Bird - Wireframes on the fly</h4> O Mocking Bird</a> é um site onde você pode montar wireframes para layouts de sites facilmente, como se você estivesse fazendo um desenho mas com elementos pré-determinados. Achei o serviço muito interessante, principalmente para mim que não manjo nada de fazer design, portanto eu posso dar uma olhada no que eu quero fazer usando os elementos pré determinados do Mocking Bird e quem sabe fazer um layout razoável para implementar, apenas revendo as cores com quem manja de verdade. :) Collecta</h4> O que eu achei interessante do Collecta</a> é a quantidade de coisas diferentes que ele traz na busca, desde twitter até Github, e isso sem contar que é tudo em tempo real, e você pode ver realmente o que está acontecendo referente a um determinado assunto. O serviço parece ser interessante para cobrir eventos, por que da para ter uma visão geral do que está acontecendo em vários lugares ao mesmo tempo, ver fotos que postaram, comentários no twitter, vídeos no youtube e etc. Buzz Volume</h4> O Buzz Volume</a> foi criado por dois colegas meus ( o [@dirs](http://twitter.com/dirs “Dirceu Pauka”) e o [@mauricio](http://twitter.com/mauricio “Mauricio”) ), e eu achei a idéia bem interessante! O que o site faz é agregar links que estão sendo bem falados no twitter, assim mantendo o usuário por dentro do que está sendo mais comentado, ou seja, um bom agregador de coisas famosas. :) Espero que nesse serviço coloquem uma feature de excluir asssuntos :P Bem, é isso! Esse post foi simples mas eu compri os serviços legais desse mes. ;) Até mes que vem. Show do ACDC Unknown — Tue, 01 Dec 2009 00:00:00 +0000 Como muitos sabem eu tive o prazer de estar no show do ACDC aqui no Brasil, que aconteceu no dia 27 de novembro de 2009. Eu não queria perder esse show por nada, por vários motivos, sendo 2 deles: Eu curto pra caramba ACDC</li> Os caras já estão bem velhinhos! Assim como o Ozzy que eu fui e já pensava que podia ser a ultima vez :P</li> </ul> O show foi no estádio do Morumbi: </a> Por sorte consegui chegar relativamente cedo ( 17:00 ) e peguei um estacionamento razoável ( na casa de alguem que fatura com isso ) e um lugar razoável na arquibancada (infelizmente nesse show eu não fui de pista): </a> O tempo castigou e tivemos a oportunidade de cantar bastante Thunderstruck ( a cada relampago começava um: "Thuuuuun der!!" ). Recebi uma bela de uma chuva enquanto estava na fila para entrar e outra enquanto esperávamos o show de abertura. Nesse meio tempo eu vi uma ligeira vantagem de ter ido de moto, por que eu estava com a minha capa de chuva na mochila e utilizei-a. :D </a> Enfim! Agora vamos ao show. (infelizmente as únicas fotos que eu tirei que ficaram razoáveis foram antes do show, as outras não dá para ver nada :P) Abertura</h3> Como muitos sabem, quem abriu o show do ACDC foi o Nazi ( não me perguntem por que...Não tenho idéia por que ele foi o escolhido ), que eu não esperava que fosse legalzinho como foi. Tocou umas musicas meio clássicas como Raul Seixas, Ira ( não tenho certeza, mas suponho que era ) e Iggy Pop. O Show foi bem curto ( cerca de 20 minutos ), mas teve a presença do Andreas Kisser e a apresentação foi rápida, legal e indolor. Show do ACDC</h3> Depois de esperar ansiosamente pela abertura do show, eis que as luzes se apagam e começa um vídeo no telão, onde mostra todos os integrantes da banda ( ou era só o vocal e o Angus? Não lembro ) dentro de um trem com algumas mulheres, e o Angus só alimentando a fornalha do trem para que ela fique no máximo. Duas mulheres amarram o Angus e tentam parar o trem, quando não conseguem elas pulam fora, e o Angus com o trem a todo vapor apenas pega sua Guitarra e o trem se colide com o fim da linha. Na hora da colisão do trem no vídeo o palco todo se acende e o ACDC inicia o show tocando Rock N' Roll Train! Uma musica muito legal para se iniciar! Nesse momento o cenário já está enfeitado com uma grande locomotiva que fica soltando fumaça enquanto eles tocam. Abaixo vai o set list que foi tocado durante o show com os meus devidos comentários: Hell Ain't A Bad Place To Be - Musica que eu gosto bastante!</li> Back In Black - Obviamente eles não podiam deixar de tocar essa musica que é um grande clássico do ACDC! Tive até que ligar para o meu primo para ele ouvir um pedaço! Essa musica é boa demais!</li> Big Jack - Essa como outras musicas que são relacionadas a mulheres tem uma coisa muito legal, que é mostrar várias mulheres do show! :P</li> Dirty Deeds Done Dirt Cheap - Nada como gritar Done Dirt Cheap! Depois de um grande Dirty Deeeeeeeeedsss! :P</li> Thunderstruck - Outra das musicas muito esperadas do ACDC, que já começa com um solinho bem legal do Angus. Uma das coisas que eu gostei pra caramba nessa musica é o aparecimento perfeito do relâmpago no telão quando todos gritavam "Thunnder".</li> Black Ice - Uma musica que eu ouvia já faz um tempo e gosto bastante!</li> The Jack - She's got the Jack! Outra musica que mostra mulheres no telão, e nessa teve até um meio strip tease do Angus ( ele é doentão...hehehe )</li> Hells Bells - Outra integração fantástica com o cenário! Antes de começar a musica desce um grande sino no palco, e o vocalista corre pelo grande palco que foi montado pelo meio da galera e se pendura no sino, dando o primeiro toque do sino da musica. Coisa Linda! :D</li> War Machine - War Machiiiiiine! ( Só quem conhece as musicas do ACDC que entende essas falas que eu coloco antes de comentar sobre a musica, por que as musicas do ACDC sempre tem uma fala que a galera se junta para falar como um eco depois do vocalista ). Essa é uma das musicas que eu mais gosto do Black Ice, juntamente com Skies on Fire ( que não está no set list do show ).</li> Dog Eat Dog - Essa foi uma surpresa! Gosto pra caramba dessa msuica, mas achei que eles não fossem tocar, e tocaram! :D</li> Anything Goes - Musica legal e eu ouço bastante, mas não é uma das minhas preferidas.</li> You Shook Me All Night Long - Musica de mulheres novamente, e não me lembro se foi nessa mas teve uma mina que lembrou a essência dos bons e velhos shows do ACDC que as mulheres levantavam a camiseta! :D:D:D</li> TNT - Hey! Hey! Hey! T....N....T! Obviamente, mais uma das clássicas do ACDC que não podia faltar num show de qualidade como esse!</li> Whole Lotta Rosie - E lá vamos a mais uma parte muito foda do cenário! Surge uma boneca gigante da Rosie no cenário ( com os peitos gigantes por sinal ), e fazendo um movimento de bater o pé que ficou muito legal.</li> Let There Be Rock - Boa e velha essência do Rock N' Roll! Me de as luzes...Me de o som...Me de a bateria...Me de a guitarra...Que se faça o Rock n' Roll!</li> Highway To Hell - Clássica e muito foda! Não tem o que dizer!</li> For Those About To Rock - Essa para mim foi a melhor musica do show! A musica é muito boa, a interação com o cenário ficou perfeita, e foi a musica final para fechar. Foi muito legal ver isso: For those about to rock.... Fire ( um canhão que fica atrás do palco dispara! ) Weeeee saluuuuute yoooou!</li> </ul> E a cada vez que tinha um "Fire!"ou um "Shoot!" um dos canhões disparava, até que no ultimo "Fire!" os 6 canhões disparam para fechar o show! Fantástico! Obviamente em algum lugar do show teve um solo gigante do Angus com direito a plataforma móvel para ele solar mais alto. :D Conclusões</h4> Foi um dos melhores shows que eu já fui ( senão o melhor ) e quem perdeu a chance de ir não sei se terá outra, e perdeu um show fascinante para quem curte. Eles tocaram as musicas que eu mais gosto( Eu gosto de uma infinidade de outras, mas as que tocaram foram todas de meu agrado, todas que eu gosto ). Rails Summit 2009 Unknown — Mon, 19 Oct 2009 00:00:00 +0000 Esse é um post para relatar como foi o Rails Summit Latin America desse ano! 😀 Já começo o post com um grande #win para a organização do #railssummit, por que eles tem tomadas para todos e wi-fi liberado para todos os participantes, o que ajuda para que pessoas como eu possam ficar postando no blog durante o evento, :) Vamos ao evento! Rails Insurgency – Chad Fowler</h4> A palestra foi muito interessante e o Chad Fowler falou sobre como é a dificuldade de implantar uma aplicação Rails em uma grande empresa quando você tem grandes gerentes que te enchem de perguntas do tipo: “Rails faz X?, “Rails faz Y” até que voc6e responda um não para que ele possa dizer: “Aháá! Então não podemos usar”. O Chad Fowler já foi um desses gerentes e decidiu passar a experiencia de um desses gerentes e por que eles pensam dessa maneira. Uma outra coisa bem legal que o Chad comentou foi sobre fazer um modelo junto com o seu cliente na hora do planejamento, até por que você consegue fazer isso facilmente com o Rails e até mostrar uma pequena funcionalidade com um Scaffold sem muito transtorno, e seu cliente pode facilmente ver se é isso mesmo que ele está pensando. Gregg Pollack – Na vanguarda da performance em Rails</h4> O Greg Pollack falou sobre page scaling Rails, comentando sobre uma grande quantidade de plugins para medir e ajudar a corrigir alguns problemas de escalabilidade que são detectados. Foi apresentado ferramentas para melhorar performance de banco de dados, para verificar quais queries que podem ser melhoradas, onde podem ser incluídos índices e outras coisas bem interessantes. No fim da palestra ele falou sobre o madmimi</a> que ajuda a lidar com um dos grandes gargalos de aplicações, que é quando se tem que trabalhar com grandes listas de e-mails. Para saber os outros assuntos que o Greg falou é só ver no blog do EnvyLabs: http://blog.envylabs.com/summit</a> Carlos Brando – Como o Rails funciona por dentro</h4> Agora começa o problema por que temos que escolher uma palestra e eu fiquei em dúvida entre a palestra do Ilya Grigorick e a do Carlos Brando</a>, mas no fim das contas resolvi assistir a do Carlos. O Carlos Brando falou sobre como o Rails funciona por dentro, usando a sua experiência na criação de um framework (que ele está fazendo na nova empresa que está trabalhando), ele falou um pouco sobre como o Rails trata as requisições, como utilizar as coisas certas de Rails quando se está fazendo um framework, e comentou um pouco sobre o framework que ele está criando como exemplo. Achei a palestra muito superficial…Achei que o Carlos fosse pegar pesado mostrando bastante coisa do Rails, mas ele decidiu mostrar algo mais simples pois ao mostrar para algumas pessoas percebeu que elas estavam achando meio massante. Enfim, como ele mesmo disse, não dá para agradar a todos, mas na minha opinião a palestra foi fraca :( José Valim – Aprenda a customizar os geradores do Rails 3.0</h4> A palestra do José Valim foi bem legal! Ele falou sobre o Thor e sobre os geradores do Rails 3, como você poderá facilmente customiza-los e como o thor pode te ajudar em suas aplicações. Ele mostrou um pouco do motivo de se trocar utilizar o thor, e por que os antigos geradores são ruins do jeito que estão. Um exemplo legal foi mostrar como um plugin tem que fazer para gerar coisas, tomando como exemplo o RSpec, que com um spec_model vai ter que gerar migrations tambem, sendo que não é do escopo do RSpec ter que se preocupar com migrations, mas do jeito que está atualmente ele apenas pode trocar o script/generate model</code> pelo script/generate rspec_model</code>. Utilizando o exemplo anterior como base foi mostrado como os novos geradores vão ajudar nas tarefas dos plugins a partir de agora. Gostei da palestra e acho que o José Valim conseguiu passar bem o que ele queria. :) David Chelimsky – RSpec e Cucumber alem do básico</h4> A palestra do chelimsky foi sobre o uso do RSpec</a> e do Cucumber</a>, que na minha opinião foi bem similar a palestra do ano passado, mas mesmo assim mostrou algumas boas práticas sobre RSpec que foram interessantes. Eu ainda tive a chance de conversar com o Chelimsky no final da palestra para fazer umas perguntas sobre o Spork e como melhorar o tempo de execução dos meus testes que demoram muito para serem executados, tornando o desenvolvimento com o autospec não tão bom quando poderia ser. Fabio Akita – Agile, além do caos</h4> A palestra do Akita foi uma grande viagem de pensamentos aleatórios dele sobre a teoria do caos baseado nos estudos que ele tem feito nos últimos tempos. Eu achei que foi muita informação para um curto período de tempo para as pessoas, mas quem conseguiu abstrair muita coisa e entender qual foi a finalidade da palestra deve ter gostado bastante, por que a idéia central é bem interessante. :) Matt Aimonetti – O Futuro do Ruby & Rails</h4> O Matt falou sobre as novidades que virão no Rails 3, sobre o que poderá ser incorporado do merb e o quanto “plugável” o Rails 3 será. Ele não falou apenas de Rails, mas falou tambem um pouco de Ruby e quais são as novidades em termos de velocidade. Desconferência</h4> E chegou a hora que muitos estavam esperando, a desconferência! 😀 Na ultima desconferência o Elomar deu show falando um pouco sobre grupos de estudo, e muita gente estava esperando coisas legais para esse ano. Teve muita coisa interessante, mas infelizmente não pude ficar até o final por causa da minha faculdade, mas o que pude ver foi: Pessoal do Guru-sp apresentando o grupo e falando sobre o crescimento e futuras atividades (eu fui o primeiro a falar! 😀)</li> George Guimarães falando do Devise</li> Aldo França contando sua história para aprender Rails e fazendo um blog em 15 minutos ( com 11 anos de idade )</li> Guilherme Chapiewsky e Henrique Bastos falando sobre os eventos e grupos que eles participam no Rio</li> </ul> Sei que teve muito mais coisas legais alem disso, mas essas foram as unias que eu pude ver e achei todas bem legais! 😀 Acho muito interessante essa idéia de desconferência, pois serve tanto para integrar o pessoal e dar risada quanto para apresentar projetos interessantes e muito úteis para alguns. Sem contar que eu ganhei um Ipod nano da ThoughtWorks</a> em um sorteio pouco antes da desconferência. 😀 Manhã do primeiro dia</h4> Agora vem a parte triste…Não pude estar no evento no segundo dia de manhã. :( O ikwa</a> não liberou todos os programadores para ficar lá em tempo integral, portanto fizemos um revezamento, e para mim ficou o segundo dia de manhã. Perdi duas palestras que eu gostaria muito de assistir. A primeira é do Carlos Vilela</a> que falou sobre o uso do Ruby na ThoughtWorks e a segunda é do Nando Vieira</a> que estava falando do Ruby 1.9. Uma coisa que me animou um pouco foi saber que as palestras eram simultâneas, portanto eu ia perder uma de qualquer jeito. Marcos Tapajós – CouchDB no Rails</h4> Como não pude estar no evento no segundo dia de manhã eu já cheguei direto para a palestra do Tapajós</a> sobre CouchDB, que por sinal foi bem interessante! O Tapajós mostrou um pouco de como é trabalhar com CouchDB e como deve ser a mudança de paradigma da saída de um banco relacional para ir para um banco orientado a documentos. Como o próprio Tapajós disse, a idéia da palestra dele era dar um Overview do couchDB e depois abrir para perguntas para tirar as dúvidas do pessoal, e na minha opinião ficou muito bom! 😀 Bruno Miranda – Rails não escala</h4> O Bruno Miranda</a> apresentou “juntamente” com o Jason Seifer (infelizmente o Jason Seifer</a> não pode estar no railssummit por problemas com a viagem, portanto apenas enviou vídeos da parte que ele ia falar) sobre “Rails não escala”, falando sobre a aplicação que está em baixo do canal de audio do MSN e como eles conseguem manter uma infra escalável usando Rails. Vinicius Teles – Do serviço ao produto</h4> Uma das melhores palestras do Rails Summit ( as palestras não técnicas são sempre as mais marcantes, por melhor que sejam as técnicas… ), onde o Vinícius contou sua história passando por bons e maus momentos com a sua empresa, começando com serviços e terminando em produto. Coisas interessantes da palestra do Vinícius foi o grande enfoque em “reserva”, ou seja, sempre tenha uma reserva em caixa para segurar a sua empresa nos piores momentos ou ajudar quando vem aquela grande oportunidade. Apenas investir em passivo ( como carros por exemplo ) quando isso não for um grande empecilho, por que no começo um carro (por exemplo) só vai te trazer prejuízo com desvalorização e manutenção. O Vinícius deu ótimas dicas para quem quer começar uma empresa, várias dicas de experiencias que ele passou, e me animou muito a preparar as coisas par a empresa que eu vou abrir no futuro. Acho que já posso começar a me preparar. 😛 Obie Fernandez – Dominando a arte do desenvolvimento de aplicações</h4> Outra palestra no mesmo nível da palestra do Vinícius ( também não técnica ), portanto muito boa! 😀 O Obie Fernandez falou sobre como dominar o desenvolvimento de aplicações, e achei muito interessante os exemplos que ele passou sobre musica, comentando da quantidade de esforço de um grupo de músicos em termos de horas e o que isso implicava em seu nível. Ainda sobre o tempo de estudo, não é “apenas estudo” por que pratica não leva a perfeição, “prática perfeita leva a perfeição”. Programação é como musica, é sempre bom pegar musicas dos outros para estudar, por que assim você pode aprender sutilezas para fazer a sua. A palestra do Obie assim como a do Vinícius teve frases chave como: Se eu estiver trabalhando e um dia descobrir que eu não estou feliz eu simplesmente saio</li> Fuck the enterprize ( muito boa! haha )</li> Pratica não leva a perfeição, pratica perfeita leva a perfeição</li> </ul> Gostei bastante da palestra, e bateu certinho com algumas coisas que estou pensando para os meus estudos para os próximos tempos. #horaextra</h4> O #horaextra foi muito legal! Tivemos um problema com o primeiro bar que fomos por que não podiam entrar menores e nem com short, portanto o Mergulhão e o Aldo ficariam de fora, então o pessoal foi para outro bar, que ficava do lado desse e lotamos o lugar 😛 Como o bar era pequeno para a quantidade de pessoas, as coisas demoravam um pouco para chegar, mas nada que uma boa conversa não pudesse ajudar você a relevar isso. A mesa era gigante, mas as pessoas que a voz alcançava eram: Carlos Brando</a>, r4f4e1</a>, Vinícius Baggio</a>, Shadow</a> e Agaelebe</a>. Batemos papo por um bom tempo, com participação de mais uma galera ( Akita</a>, Rafael Rosa</a>, Thiago Scalone</a> …. ), e acabei saindo de lá mais de 00:00. Aqui chega o fim do evento e o que fica são os bons momentos passados por lá, o conhecimento adquirido e a vontade de participar novamente no ano que vem! Parabens aos organizadores ( e patrocinadores! ) do evento, por que ficou ótimo! Se quiser ver as fotos que eu tirei no evento veja o album no meu picasaweb</a>. Serviços legais de outubro Unknown — Sun, 04 Oct 2009 00:00:00 +0000 Já estava me esquecendo de postar sobre os serviçoes legais desse mes! :P Estava com poucos quando lembrei, mas não demorou muito para que eu lembrasse de alguns muito bons. Vamos lá! yUML<</h4> O yUML</a> é um serviço para se criar UML</a> facilmente utilizando apenas uma URL com determinadas marcações. O caike que me mostrou no ultimo post quando eu tinha mencionado sobre criação de UML</a>. Valeu Caike</a>! Gliffy</h4> Continuando em diagramas e UML temos o Gliffy</a> que também faz uma grande quantidade de diagramas diferentes. Esse quem me mostrou foi a Suelen</a>! Valeu Suelen! =* Pivotal Tracker</h4> Para quem não connhece, o PivotalTracker</a> é uma ferramenta para gestão de projetos utilizando Scrum</a>! Ele utiliza várias ferramentas que são muito úteis quando se tem uma equipe que está aplicando a metodologia Scrum, como gráfico burndown, média automática de pontos por semana, agendamento automático de tarefas de acordo com a quantidade de pontos por sprint da equipe e mais outras coisas bem interessantes! Já trabalhei utilizando o Pivotal e recomendo! Scrumy</h4> O Scrumy</a> é outra ferramenta muito interessante e bem simples para se trabalhar com Scrum, principalmente para equipes remotas. Ele cria um kanban board virtual, onde você pode arrastar os post-its para as próximas áreas ( todo, wip, verify, done ), e ter uma visão mais ampla das atividades facilmente. Esse mes é só isso! Espero que seja útil para alguém! Instalando e configurando o monit Unknown — Thu, 10 Sep 2009 00:00:00 +0000 Esses dias eu peguei para instalar o monit no servidor da empresa que eu trabalho e sofri um pouquinho com algumas coisas básicas, portanto decidi postar aqui para que seja útil para quem quer começar a utilizar o monit. Se você usa Ubuntu, você pode fazer download do Monit por apt-get: sudo apt-get install monit</code></pre> Se você não usa Ubuntu ou quer a ultima versão do Monit, então faça download do tar.gz http://mmonit.com/monit/download/</a> e compile. O Monit tem 2 dependencias: bison</li> flex</li> </ul> Eu resolvi as 2 facilmente utilizando o próprio apt-get: sudo apt-get install bison flex</code> Agora é só partir para compilar os fontes! ( prefiro compilar dos fontes em certas ocasiões para pegar a ultima versão ): ./configure make sudo make install</code></pre> E pronto! Lá está o seu monit instalado! Agora é o momento da configuração. :D O monit utiliza o arquivo chamado .monitrc para saber o que deve ser monitorado e com quais parâmetros, portanto crie um arquivo na sua $HOME com o nome de .monitrc</code>: vim $HOME/.monitrc</code></pre> Claro que usarei o vim para isso (qual outro poderia ser né? haha). Agora você deve criar o seu próprio arquivo de configuração dizendo o que o monit deve monitorar e quais critérios deve usar. Você pode pegar alguns exemplos de arquivos como o do pessoal do mongrel</a>, ou até mesmo da documentação oficial do monit</a> e criar o seu baseado nele. A syntax desse arquivo é de fácil entendimento. :) Para e-mails eu utilizei a minha conta do Google Apps com a seguinte configuração: set mailserver smtp.gmail.com port 587 username "pothix@pothix.com" password "abc123" using tlsv1, with timeout 15 seconds</code></pre> Com todas as configurações arrumadas o monit já pode ser iniciado: monit</code></pre> E agora você já tem vários comandos para utilizar, é só dar uma lida na documentação do monit para ver o que é possível fazer</a>. Espero que seja útil para quem ainda não usa nenhuma ferramente de monitoração e gostou do monit. :) Serviços legais de setembro Unknown — Thu, 10 Sep 2009 00:00:00 +0000 E lá vamos nós novamente para mais um post sobre os serviços legais que eu encontrei esse mes. Creately</h4> O Creately</a> é um site para se fazer diagramas! Eu estava procurando por isso faz bastante tempo e nunca tinha achado um satisfatório, mas esse parece ser muito bom! Com ele é possível fazer uma grande quantidade coisas, como diagramas de classe, fluxograma, esqueletos de layout e mais um monte de coisas legais e depois exportar para alguns formatos. Groove Shark</h4> O Groove Shark</a> é um site fantástico para se ouvir musicas! Sabe quando você está na faculdade na internet pesquisando sobre um trabalho e tem aquela saída para fone no computador e você pode ouvir musicas mas não tem um lugar legal? Acesse o GrooveShark faça uma pequena playlist e se divirta. Gostei por que eles tem uma grande variedade de musicas lá e a interface é bem leve e bonita. TutsPlus</h4> O TutsPlus</a> é um site que possui uma grande quantidade de tutoriais de qualidade sobre vários tipos de assuntos. O que achei interessante é que os materiais são divididos em sites diferentes e todos os tutoriais são moderados, portanto quase todo o conteúdo que você vê por lá é de muito boa qualidade. Eu acompanho as atualizações do NetTuts</a> por que sempre tem um conteúdo que me interessa referente a web, seja Javascrit, PHP, Rails ou várias outras coisas interessantes. Bem, é isso! Espero que esses links sejam úteis para mais alguem além de mim! :D Meme: Game design ao Extremo Unknown — Sat, 22 Aug 2009 00:00:00 +0000 Estou escrevendo esse post por que fui convocado para esse meme pelo Bruno Croci</a>, que foi meu parceiro no desenvolvimento de um dos games vencedores do GameJam do itaú cultural</a>, o Robotz Warehouse</a>. A idéia do post é mostrar alguns games interessantes e falar a sua opinião sobre eles. As regras são: Liste quantos jogos em Flash quiser. Preferencialmente aqueles que, por algum motivo de design chamaram sua atenção.</li> Diga o que desses jogos te chamou a atenção, seja em quantas linhas quiser.</li> Repasse para outros blogs.</li> </ul> Há algum tempo eu gostava muito de ficar jogando jogos de lógica em flash na internet, mas de um tempo para cá eu parei devido a correria, mas com esse post eu consegui reviver muitos jogos legais. São eles: Orbox</h4> O orbox</a> é um jogo muito legal, e o que mais me impressionou nele é a forma que ele consegue prender o jogador por ser um jogo bonito, que parece ser muito fácil mas mostra que você precisa realmente usar a cabeça para poder chegar a terminar o jogo. Eu joguei por algumas madrugadas para poder chegar ao fim! =) Cowmaze</h4> Cowmaze</a> é um jogo fantástico! Acho que tem uma idéia simples e interessante, que também explora a lógica como parte principal do game e isso sempre me atrai. O game é muito bem desenhado, apesar de ter um tema mais infantil, é muito bem feito e bonito de se olhar. Esse game é bem completo, possui vários níveis de dificuldade, sendo que algo que parece ser simples de ser resolvido se torna totalmente complexo se você não escolher o caminho certo. Uma coisa que esse game tem de vantagem em cima do Orbox? Passwords! Pude jogar esse jogo por muito tempo, por que ele sempre tinha um password para eu conseguir voltar de onde eu estava, enquanto o Orbox sempre me fazia recomeçar tudo novamente. Mystery of time and Space - M.O.T.A.S</h4> O que mais me chamou a atenção nesse game</a> (além de ser um jogo de investigação, é claro) foi a história e o ambiente ao qual o jogo introduz o jogador. Esse jogo consegue usar o fato de que você tem que explorar um cenário e coloca você realmente dentro do game entendendo que você está realmente confuso dentro do jogo. Eu realmente recomendo jogar e tentar chegar até o final! ;) Chronotron</h4> A idéia do chronotron</a> é fantástica, e me foi recomendada por um físico</a> que falou que a idéia dele é realmente legal e para quem realmente entende de física vai reparar muitas coisas legais. O jogo é simples mas é muito divertido! Mais uma vez ele trabalha a parte lógica e faz com que você tente muitas vezes fazer as suas cópias trabalharem da maneira correta, o que por sua vez é muito desafiador e divertido :) Light Bot</h4> Essegame</a> mostra muito bem como é ser um programador. Você tem tipos de ação e você deve usá-las da melhor maneira possível para fazer com que o robô chegue a seu destino, e como sempre, as ações são limitadas e você precisa fazer uso de funções para utilizar as ações da manera correta, sempre reutilizando as ações dentro de funções. Esse jogo é ótimo para programadores (seja DRY</a>) por fazer você pensar em como fazer as coisas corretas, e tambem para mostrar para as pessoas que não programam como é mais ou menos programar. É um game que realmente vale uma olhada, seja você programador ou não. Esses foram os games que me prenderam por um longo tempo e realmente valem a pena de ser lembrados. Agora eu devo indicar mais pessoas para continuar esses posts, e os indicados são: Infog</a></li> Leticiando</a></li> Griebeler</a></li> Mario Rinaldi</a></li> </ul> Espero que apareçam outros posts para dar sequencia e para eu conhecer jogos legais que estão perdidos por aí, além de analizar idéias legais para games. Saldo final das férias de julho Unknown — Mon, 17 Aug 2009 00:00:00 +0000 Eu sempre digo que a faculdade me atrasa bastante, por que eu não consigo estudar/fazer um monte de coisas que eu tenho vontade para me dedicar as coisas que a faculdade me obriga a fazer. Se a faculdade é bom ou ruim não é discussão para esse post, mas resolvi postar a quantidade de coisas que eu consegui fazer nessas férias aproveitando que eu não precisava me preocupar com a faculdade, assim deixando o tempo da noite e a cabeça menos preocupada: Leituras:</h4> Terminei de ler O senhor dos anéis! ( faltavam mais de 13 capítulos, sendo que cada um tem cerca de 20 folhas )</li> Terminei de ler o High Performance Websites</li> </ul> Screencasts</h4> Assisti o screencast antigão ( na época do lançamento do Rails 2 ) do Akita sobre RESTful Rails</li> Screencast sobre RSpec Basics</li> Screncast sobre RSpec Mocks and Stubs</li> </ul> Eventos:</h4> Encontro do Guru-sp</a></li> GameJam</a></li> </ul> Trabalhos:</h4> Iniciei um novo projeto pessoal ainda em back mas falarei o que é em breve e já estou terminando</li> Trabalhei um pouco mais e aprendi bastante coisa no Ikwa nos momentos mais tranquilos com a equipe</li> </ul> Blog:</h4> Consegui postar sobre os jogos que eu estava jogando no PSP ( Diablo</a> e Spiderman</a> )</li> Finalmente postei meu review do Pragmatic version control with Git</a> que já fazia meses que estava de molho</li> Postei meu review do O senhor dos anéis</a></li> Postei meu review sobre o High Performance Websites</a></li> Finalmente fiz meu primeiro post sobre Vim</a></li> Postei sobre como instalar o Allegro 4.2.2</a></li> Postei sobre como foi o GameJam</a></li> Postei sobre o Evento do Guru-sp</a></li> </ul> Open Source</h4> Incluí mais uma funcionalidade no meu plugin do Wordpress</a></li> Fiz algumas traduções para o Git Ready</a></li> Escrevi um pouco para o vimbook</a></li> Contribui para o plugin remarkable_paperclip</a> do Diego Carrion</li> </ul> Game Develo</h4> Parcicipei de um concurso de desenvolvimento de games</li> Aproveitando o concurso consegui aprender bastante sobre Allegro</li> Fiz networking com um pessoal legal que tambem conhece bastante coisa sobre games</li> </ul> Além de tudo isso tive que fazer um trabalho que a professora ( que não tem noção alguma ) deixou para entregar depois das férias, e estudar para Estrutura de Dados que não fui muito bem ( o curso é anual ) e vou ter que melhorar até o final do ano. :( Essas férias me foram muito custosas em termos de saúde tambem... Gastei mais de 1000 reais somente com saúde! :( Bem, é isso! Acho que não dá para responder: "Ahh...Não fiz nada nessas férias" :P Um pouco sobre o Vim Unknown — Fri, 14 Aug 2009 00:00:00 +0000 Aqui começa uma série de artigos sobre por que eu gosto de usar o VIM para programar. Uma das primeiras coisas que eu gostaria de comentar é sobre a quebra de paradigma que você deve ter quando começa a usar um editor como o vim que tem vários modos de operação, ou seja, não é mais apenas digitar, pois cada modo de operação tem o seu modo de agir. Os modos de operação são os seguintes: Inserção</li> Visual</li> Normal</li> Comandos</li> </ul> Modo de inserção</h4> O modo de inserção é um modo simples para se inserir texto sem nada muito complexo, você se sentirá usando um notepad se usar somente o modo de inserção. Modo visual</h4> Com o modo visual você pode selecionar facilmente trechos de texto, linhas inteiras e blocos de texto. Um exemplo bem legal de uso de blocos no Vim pode ser visto no blog do TaQ</a>. Modo normal</h4> Agora sim as coisas ficam legais! No modo normal, que é o modo que você mais fica no Vim, você pode fazer as coisas mais interessantes! Ok, falei...falei...e não mostrei o por que o modo normal é tão poderoso né? Bem, são coisas como essas: Dentro de aspas podemos dar um ci" e ele já excluiria todo o conteúdo que está dentro das aspas e deixaria você em modo de inserção para inserir um novo conteúdo</li> Parar em cima do número 20 e quer adicionar 7? Apenas faça ctrl+a</code> e ele fará a soma em cima desse número</li> E se ao invés de soma vc quiser a subtração dos valores acima? Apenas faça ctrl+x</code> e ele fará a soma em cima desse número</li> É claro que você não vai ficar repetindo esse monte de coisas que você fez aí em cima se tiver várias ocorrências e você não quiser fazer um "find and replace", por que você pode usar o . (ponto) para fazer a sua ultima ação novamente.</li> Quer trocar as linhas de posição? Moleza! ddp ( sendo dd para excluir uma linha, que fica no buffer, e p para colar a linha do buffer )</li> Está no começo da linha e quer ir para aquele parentese? f( e pronto, você já estará lá!</li> Quer ir para um caracter antes do parentese? t( ta na mão! :)</li> </ul> Enfim...Tem muitas outras coisas legais a se fazer sem que você precise tirar a sua mão do teclado. Modo de comandos</h4> E o modo de comandos é onde você tem uma segunda linguagem de programação alem da que você está usando pra programar, e lá você pode tanto usar comandos de loop como: for i in range(1,10) | put ='192.168.0.'.i | endfor</code></pre> OBS: créditos ao Sergio nesse post</a> Que imprime uma faixa de IPs de 192.168.0.1 até 192.168.0.10. Ou você pode alterar as funcionalidades e opções do editor utilizando :set</code> ou outras comandos interessantes. Use o Vim como ele foi feito para ser usado</h4> Outra quebra de paradigma que deve ser usada é usar "hjkl" para se movimentar pelo texto, sempre usando os dedos indicadores sobre o "j" e o "f" que é o padrão de digitação, e você vai ser que você vai precisar tirar a mão do teclado para fazer outras coisas poucas vezes, e pelo menos para mim as coisas parecem bem mais fáceis. Isso lhe força a sempre usar esc</code> (ou ctrl+[</code>) após fazer alguma coisa, deixando o modo normal livre para uso. Customização</h4> O Vim pode ser facilmente incrementado com plugins, temas e outras coisas que tornam ele bem customizável, e você pode deixar ele com a sua cara. Atalhos são facilmente configuráveis no seu .vimrc, assim como configurações como highlight de busca, espaçamento para scroll, e mais muuuiiitas opções que obviamente não caberão nesse post. Concluindo</h4> A idéia desse post é falar que para se usar vim você precisa estar disposto a mudar muita coisa que você sabe, e a curva de aprendizado não é uma das mais fáceis, mas quando você está no meio dela você percebe o quanto é legal e acaba se viciando no negócio! hehe Como o Vim é bem configurável pode acontecer de você ficar tentando implementar ele para ficar igual ao seu antigo paradigma ( modo de inserção para sempre ), mas isso não vai de ajudar muito e vai te abstrair toda a força do Vim. É isso! Nos próximos posts sobre vim pretendo postar dicas, referências legais e falar bem mais aprofundadamente de algumas ferramentas. Instalando o Allegro 4.2.2 no Linux x86 Unknown — Wed, 12 Aug 2009 00:00:00 +0000 Como mencionei no meu ultimo post</a> eu parcicipei do GameJam do Itaú cultural e desenvolvi um jogo com Allegro. Agora com o jogo pronto estou criando arquivos executáveis para divulgar e tinha me esquecido da diferença de arquitetura no Linux, assim compilei apenas para meu Linux x64. Quando me dei conta que não funcionou no computador do trabalho por que eu tinha um binário x64, eu tive que instalar o Allegro no computador de lá para poder fazer funcionar também em Linux x86. Pensei eu: "Vai ser moleza, assim como foi instalar o Allegro 4.2.2</a> no notebook x64" </blockquote> E lá fui eu: ./configure make</code></pre> Ué...Deu um problema bizarro com o FNSTSW no make, então não vai ser tão fácil assim...E lá vamos nós procurar na internet. Procurando eu descobri</a> que tem realmente um erro em uma parte Assembly do código do Allegro para x86 que está errada na versão 4.2.2 que provavelmente foi consertada nas versões futuras, mas nesse caso tive que arrumar na mão: No arquivo src/i386/icpus.s</code> alterar a seguinte linha (tirar a que tem um menos e colocar a que tem um mais): fninit movl $0x5A5A, %eax - fnstsw %eax + fnstsw %ax cmpl $0, %eax jne is_fpu_not_found</code></pre> E assim eu consegui compilar certinho! :D Quando tentei rodar meu binário me deparei com o seguinte erro: "error while loading shared libraries: liballeg.so.4.2: cannot open shared object file: No such file or directory" ¬¬ Pesquisando na internet novamente eu descobri que estava faltando eu adicionar o diretório /usr/local/lib</code> ao meu LD_LIBRARY_PATH</code>: No meu .bashrc: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib</code></pre> OU Editar o meu arquivo /etc/ld.so.conf</code> e incluir /usr/local/lib</code> no final do arquivo e depois rodar o comando ldconfig</code> como root ;) Com isso eu consegui finalmente compilar ojogo e fazer o meu binário rodar o meu jogo normalmente. :) Espero que seja útil para mais alguem. GameJam Unknown — Wed, 12 Aug 2009 00:00:00 +0000 </a> Como alguns sabem no final de semana passado ( dias 7, 8 e 9 ) eu participei do GameJam do Itaú cultural</a>. Nesse evento os participantes tinham que formar equipes de até 4 pessoas e fazer um jogo em 48 horas, sendo que o tema ao qual o jogo devia responder só seria passado na sexta feira as 19, e teríamos até as 19 horas do domingo para entregar o jogo pronto utilizando qualquer plataforma para desenvolvimento. Pois bem, o que eu falei acima resume bem as regras do evento, agora vamos a minha situação. Fiquei sabendo na segunda feira pelo CrociDB</a> que teria esse concurso e que tinha até quarta feira para se cadastrar, e eu tinha acabado de fazer uma mini-cirurgia para tirar um dente, portanto estava sentindo dores e tomando 4 tipos de remédios diferentes e não pude confirmar nada devido a esse motivo, mas a vontade era grande. Enquanto eu não confirmava o CrociDB</a> ia procurando pessoas para a equipe. Quarta feira (último dia para inscrição chega) e eu já estava um pouco melhor e decidi me inscrever! Procurei por outras pessoas para compor a equipe, alguns descartei logo de cara por que sabia que ia ficar arrumando desculpinha para não participar, ou não teria peito o suficiente para aguentar a competição, então nem chamei, outros sabia que infelizmente não poderiam participar por motivo de força maior (fez falta hein Rafael Masoni</a>) , e teve ainda os últimos que eu achei que participariam e fui chamar mas me decepcionaram... Início do contest</h4> Sexta feira tudo preparado e lá vou eu as 19 para o Gamejam (que foi na faculdade Anhembi Morumbi</a>), e após me perder um pouco ( para variar ) cheguei em cima da abertura e recebemos o tema: "Maquinas e computadores podem tomar decisões inovadoras?" </blockquote> E com isso lá se vai o nosso pensamento... Criar um robô em 2d no estilo side scroller?</li> Criar um robô fazendo algum tipo de shooter?</li> Criar um braço robô que faz algo?</li> Como ele seria inovador?</li> Ele seria inovador?</li> Como são as decisões dos computadores atualmente?</li> </ul> E com essas várias perguntas chegamos a conclusão que um computador sozinho não pode tomar decisões inovadoras, ele apenas é programado para uma determinada finalidade, nunca cabe a ele as decisões finais com novas idéias. Com isso em mente nosso game foi baseado num braço robô que distribui caixas num armazém seguindo sua própria ordem, supostamente tentando uma maneira inovadora de organização de cores que pode ou não estar certa, e cabe ao jogador organizá-la da melhor maneira possível. Obviamente a idéia inicial não se fechou tão fácil, e fomos desenvolvendo ela de acordo com a evolução do game. Com uma base inicial desenvolvida passamos para o desenvolvimento! :D Preparamos o ambiente com Allegro e algumas classes que o CrociDB</a> usa para facilitar algumas coisas e eu dei uma introdução sobre o workflow do Git para trabalhar utilizando controle de versão</a>. Usamos um roteador para conectar os 2 notebooks e compartilhar um repositório para os códigos, por ssh mesmo, que infelizmente deixava a transferência muito ruim devido ao uso do Cygwin no Windows, mas não fui um grande empecilho, foi apenas chato. Tenho que admitir que eu sou um zero a esquerda em Allegro e fui com a cara e a coragem participar desse contest, mas eu sabia que isso me traria muita experiência, por que eu sei que o CrociDB</a> conhece bastante de Allegro e de desenvolvimento de games em si, e eu só comprovei isso durante todo o contest, ele já conhecia bem o conceito de desenvolvimento de games e tem bastante experiência com erros que podem acontecer. Ficamos programando desde as 21 mais ou menos até as 5 da manhã e resolvemos ir para casa descansar para voltar no sábado a noite e ficar até terminar o game. A primeira vista achei o pessoal das outras equipes meio acuado, cada equipe isolada em suas mesas, excluindo apenas o pessoal que já se conhecia ou que era da faculdade. Momento Hard work</h4> </a> Voltei no sábado as 19:30 para a programação e o CrociDB</a> já estava por lá programando fazia alguns minutos e já tinha resolvido alguns probleminhas. Então já começamos a programar outras funcionalidades e fazer os desenhos para o jogo, que por sinal foi a parte mais difícil para nós, tendo em vista que nenhum dos dois tem a arte do desenho assim como as outras equipes tinham ( vi muitos desenhos e trabalhos legais ). Eu assumi uma boa parte dos desenhos para deixar o CrociDB</a> mais focado na programação. Durante o domingo tivemos vários problemas, como o não funcionamento do teclado do notebook do CrociDB</a>, nos fazendo perder um tempo e ir para o laboratório usar um teclado USB, que levou a outro #fail, por que levamos o roteador e não prestamos atenção que a fonte não era bivolt, assim queimando a fonte do roteador...Ou seja...Nada de Git na parte final do projeto... No laboratório conseguimos finalizar o jogo e encontrar umas midis legais até as 14:30 mais ou menos, quando preparamos as coisas para entregar o projeto final. Ao entregar o projeto e ver a organizadora testando percebemos que faltou uma dll para o allegro funcionar no Windows, e tivemos que pegar o projeto de volta umas 2 vezes para encontrar a dll certa, mas enfim funcionou. :) Networking</h4> Depois de entregar o projeto aproveitamos para fazer um Networking com alguma das outras equipes. Durante o evento estávamos sempre vendo algumas pequenas cenas dos outros jogos e algumas ferramentas, e uma que chamou bastante a atenção foi da equipe que estava ao nosso lado (Danilo, Gabriel, Theo e o Mario que eu não conheci) que estava desenvolvendo um game totalmente em blender! (assim que eles divulgarem o game eu posto o link aqui). O game deles ficou muito legal e o pessoal é muito gente fina também, foi muito válido conhecê-los! :) Vi por cima mais alguns games que estavam em fase de produção ainda, e conheci algumas outras pessoas como o Danilo Vin (só conheço ele assim até agora...hahaha) que estava fazendo as artes do grupo dele, muito boas por sinal, mas não vi o jogo finalizado. Revi tambem o Speeder já tinha visto na campus party mas não tinha conversado muito. Considerações</h4> Finalizando, eu acho que esse contest foi muito legal,dormi apenas 40 minutos de sábado para domingo, mas foi minha primeira experiência com competição de desenvolvimento de games, meu primeiro contato mais próximo com Allegro, revi alguns conceitos de C++, conheci pessoas interessantes, vi alguns jogos serem criados do zero... Mesmo se nosso jogo não ganhar (o que é provável....hehe) esse contest valeu muito a pena! O nosso game não ficou exatamente como queríamos por que além dos problemas, não conseguimos aplicar todas as idéias que tínhamos em apenas 48 horas. Uma coisa que me deixou muito feliz foi ter conseguido fazer esse jogo usando apenas Software Livre! Utilizamos Inkscape, Gimp, Allegro e GNU/Linux. O Croci utilizou Windows para compilar a versão windows do jogo, e não tivemos sequer um problema de compatibilidade entre plataformas. Para quem quiser dar uma olhada no nosso game, pode baixar ele no GitHub (o código não está um dos melhores, mas leve em consideração que foi um contest de 48 horas...hehe): </a> </a> Código fonte</a> Download do pacote</a> executáveis no diretório bin</code></li> </ul> Serviços legais de Agosto Unknown — Thu, 06 Aug 2009 00:00:00 +0000 E lá vamos nós com mais um post (que felizmente estou conseguindo manter mensal) sobre os serviços legais que eu vi no mês passado e estou usando esse mês. TypingWeb</h4> O TypingWeb</a> é um serviço web que possui vários tutoriais para aprender a digitar corretamente. Eu estou treinando digitação já faz um tempo utilizando o TypeRacing</a> e um programinha para Linux chamado gtypist</a> que tambem é bem legal para treinar. Achei esse site fantástico, e o mais legal de tudo é que tem uma versão em português, então eu posso passar para outras pessoas (como a minha mãe por exemplo) que tambem querem aprender a digitar melhor mas não se dão bem com o inglês. GetClicky</h4> O GetClicky</a> é serviço de estatísticas assim como o Google Analytics, mas ele possui muitas ferramentas interessantes, como monitoramente de palavras chave no Twitter, estatísticas em tempo real e mais algumas coisas interessantes que faz valer a pena pelo menos testar o serviço! ;) LastFm</h4> Sim, estou falando da Last.fm</a> que já está a tanto tempo aí, mas resolvi comentar por que eu estou lá há mais de 1 ano e só agora comecei a utilizar de verdade. Quando eu entrei pela primeira vez para saber como funcionava eu fui no site e tentei ouvir várias musicas. Umas eram cortadas, as playlist só podiam ser tocadas por usuários premium e não sei o que...Ou seja, achei uma porcaria. Nos ultimos dias eu conversei com um colega meu que me disse que deixava seu player dando tracking das musicas que ele ouvia e mandando para o last.fm, e finalmente eu descobri a finalidade do last.fm (noob), e realmente é bem legal ter um perfil numa rede social de musicas, onde seus amigos podem ver o que você anda ouvindo e comparar automáticamente o perfil musical. Bem, esses são os 3 serviços que eu tenho para compartilhar esse mes! E espero que sejam úteis para vocês assim como são para mim. :) High Performance Websites Unknown — Thu, 30 Jul 2009 00:00:00 +0000 Mais um dos livros que eu consegui terminar de ler nas férias! O livro fala sobre performance de front end, como fazer as suas páginas carregarem mais rapidamente e fornecer uma melhor experiência para o usuário. O livro começa explicando um pouco sobre o HTTP, seus métodos e utilizações, e depois inicia as sobre as 14 regras para ter um website mais performático. Eu vou tentar mostrar um pouco de cada uma das regras que o livro aborda, mas é claro que sem os grandes detalhes, comparações e exemplos que o livro dá, que são muito amplos e interessantes para se entender, mas vou dar uma visão geral de qual é o conteúdo da regra, para te chamar para comprar o livro e ler (ou não...hehhe). As 14 regras são: Faça menos requisições HTTP</h4> Obviamente se tivermos menos requisições HTTP teremos páginas mais rápidas, então o livro recomenda várias técnicas legais como combinar imagens e usar estampas CSS, combinar scripts para evitar várias chamadas, assim chamando um script só, e tambem combinar folhas de estilo. Use uma Rede de Distribuição de conteúdo</h4> Distribua seu aplicativo de diferentes servers distribuídos geograficamente, pois assim você conseguirá entrega de pacotes mais rapidamente para determinados tipos de usuarios. Adicione um cabeçalho expires</h4> Sempre usar bem os cabeçalhos expires dos pacotes, para que o browser possa controlar de maneira correta o cache. Utilizando expires para datas futuras você cosegue um ótimo ganho de performance, por que não vai ser necessária outra chamada HTTP, pois o browser vai saber que seu cache não expirou e vai manter os arquivos já baixados. Obviamente isso deve ser bem controlado para você saber o que deve ficar no cache e quando substituir determinadas coisas (que podem ser substituidas alterando o nome, por exemplo). Componentes gzip</h4> Sempre usar o mod de gzip (se vc estiver usando apache), pois os ganhos são muito grandes, e chegam a mais de 50% do total de tempo final de renderização da página. #### Coloque as folhas de estilo no topo Um argumento bem legal para esse! O autor do livro mostrou suas experiências com o arquivo CSS em outros lugares que não são o topo e percebeu que a página esperava pelo CSS para poder continuar renderizando a página, portanto reduz a experiência do usuário, que ficará com uma página em branco enquanto aguarda, sendo que poderia estar vendo aos poucos a página. O que faz o browser esperar que o CSS seja carregado é o fato de ele não ter que renderizar duas vezes (uma com o css padrão do browser e outra com o seu CSS personalizado). Coloque os scripts no final</h4> O argumento para esse é que a pagina sempre para de carregar os outros componentes enquanto está carregando os scripts, por que eles podem alterar a página com algum document.write, e muitas a ordem precisa ser mantida, portanto com os scripts no final da página você vai retardar menos o carregamento, pois quando estiver carregando o script o usuário já vai ter uma boa parte da página para se intreter. Lembrando que nem sempre é possível colocar o script no final da página, pois as vezes os elementos precisam do script carregado para fazer determinadas coisas, mas sempre que possível a sua performance pode ser melhorada com os scripts no final. Exite expressões CSS</h4> Todos sabemos que expressões CSS ( usando expression ) não é bom, e o livro demonstra alguns por que's disso que não vou abordar, apenas digo: Não use! Deixe o Javascript e o CSS em arquivos externos</h4> Interessante essa parte, por que como eu pensava, realmente deixar o CSS e o Javascript embutidos na página é mais rápido, mas quando se tem Javascript e CSS em arquivos separados e com um expires configurado você tem uma melhor resposta por que os scripts seriam carregados uma vez só e depois mantidos em cache enquanto várias páginas ficariam menores para carregamento. Reduza as pesquisas em DNS</h4> Nesse capítulo ele fala um pouco do tempo que demora para resolver um DNS e que é possível fazer caches de DNS Minimize o Javascript</h4> É comentado um pouco de ofuscamento de Javascript, quando você tira todos os espaços e caracteres inúteis do seu javascript deixando ele funcional e mais leve. Quando se usa Gzip essa técnica ajuda pouco, pois o texto já vai ser compactado, mas mesmo assim ainda há ganho, e um comentário pessoal: Se você não altera esse javascript com frequência, por que não? :) Evite redirecionamentos</h4> Os redirecionamentos são reponsáveis por uma boa parte do tempo de uma requisição, deixando o usuário vendo uma tela em braco nesse meio tempo, portanto não são nada bons para um website. O livro trata de algumas formas para evitar redirecionamentos, como alias do apache por exemplo. Remova scripts duplicados</h4> Parece estranho a primeira vista mas realmente acontece dependendo do tamanho do seu código e a quantidade de CSS e Javascript que você possui em sua página. O autor resolveu colocar esse tópico analizando grandes sites da internet e percebendo que vários deles possuia esse problema, gerando requisições em vão. Configure as Etags</h4> Use-as ou deixe-as! As Etags podem ajudar bastante na performance se bem configuradas e o livro dá vários exemplos de como isso pode ser feito, alem de uma explicação legal do que são as Etags. Faça com que o AJAX se aproveite do cache</h4> O livro descreve alguns exemplos onde o cache pode ser utilizado para aplicações com AJAX (utilizando expires com data futura) e outros onde realmente é dinâmica demais para se usar um cache. É interessante para se descobrir maneiras diferentes de se lidar com a performance e como ela se aplica para o seu caso. Analizando 10 grandes sites</h4> Essa foi uma parte que eu gostei bastante de ler, por que ele mostra grandes sites que estamos acostumados acessar ( os sites analisados nesse capítulo são: Amazon, AOL, CNN, eBay, Google, MSN, MySpace, Wikipedia, Yahoo, Youtube ) e mostra as partes boas e ruim que foram implementadas, e assim você ve com ótimos exemplos o que poderia ser feito, juntamente com as ferramentas utilizadas para a medição de cada uma das funcionalidades, e você pode muito bem utilizar as mesmas ferramentas para medir o seu website. Conclusão</h4> O livro é muito legal para se saber como trabalhar bem uma performance de front para você proporcionar uma melhor experiência para o seu usuário, deixando uma navegação mais rápida. Algumas das coisas que o livro aborda são extremas (necessárias para grandes sites, como no caso do autor, o Yahoo!), e muito provavelmente não são totalmente úteis em pequenos websites, mas a grande maioria é totalmente aplicável. Eu particularmente gostei bastante do livro, mesmo ainda não aplicacando tudo o que o livro fala, consegui ter uma boa noção de boas práticas e experiências de alguem que já trabalhou com isso e tem bons argumentos para lhe dizer por que isso seria uma boa escolha. Eu recomendo! :) Instalando gems do GitHub manualmente Unknown — Tue, 28 Jul 2009 00:00:00 +0000 Esse vai ser um post rápido para relatar um problema que eu tive ( e ainda estou tendo ) para instalar gems do GitHub. Por algum motivo bizarro (nem tanto assim, parece ser dns, mas já tentei opendns e nada) a página http://gems.github.com</a> não abre de maneira nenhuma, enquanto a navegação continua normal sem nenhum problema... A consequência disso é que eu não consigo colocar o source do github nas minhas configurações do Rubygems. :( Tendo em vista que eu não conseguiria utilizar gem install para nenhuma gem que vinha do GitHub tive que dar um jeito de instalar manualmente. :) O que fiz foi acessar a página do GitHub referente a gem que eu queria instalar, que no caso é a kitabu</a> do fnando</a>, pegar o link de clone e clonar: $ git clone git://github.com/fnando/kitabu.git</code></pre> Mas ae que está o lance que eu demorei para encontrar (noob), para uma gem ser instalada localmente ela precisa estar empacotada, e no GitHub você baixa direto o código fonte. Para empacotar: $ gem build kitabu.gemspec</code></pre> Agora sim eu tenho o arquivo kitabu-0.3.3.gem</code> que eu posso utilizar para instalar localmente! Para instalar é só utilizar o gem install padrão informando o arquivo a ser instalado: $ gem install kitabu-0.3.3.gem</code></pre> E pronto! Lá está a minha gem instalada! Espero que isso seja útil para mais alguem que precise empacotar as suas gems. :) Lord of the Rings Unknown — Sat, 25 Jul 2009 00:00:00 +0000 Chegou o momento que eu estava esperando há vários meses.... Após terminar de ler, vou escrever sobre O Senhor dos Anéis! :D Todos que me conhecem sabem como eu sou apaixonado pelo mundo de O senhor dos anéis na verdade sobre histórias medievais e o Senhor dos anéis é foda), e eu só tinha assistido o filme (mais de 10 vezes o primeiro, e milhões de vezes os outros 2) e não tinha lido o livro ainda, o que me deixava inquieto, pois eu sabia muito bem que o nível de riquezas e detalhes do livro ia muito alem do que eu podia imaginar, sem contar que muita coisa foi cortada no filme (obviamente) para que se fosse feita uma boa adaptação. </a> Esse ano eu comprei a versão full do livro com os 6 livros, e não divididos em 3 versões encadernadas, por que queria me gabar de ler um tremendo monstro de 1200 páginas (haha), e adotei alguma disciplina para ler, pois por que se você encarar 1200 páginas para ler como se fosse um todo você vai procrastinar bastante. O que fiz foi dividir por capítulos e a cada dia que se passava eu lia um capítulo. Não sei quanto tempo exatamente levei para ler esse livro, mas como as coisas foram bem planejadas, eu consigo supor que levei cerca de 62 dias (São 62 capítulos divididos entre 6 livros), o que é um tempo razoavelmente bom para se ler um livro desse tamanho (pelo menos para o meu ritmo). O que eu falo abaixo não vai ser nenhum spoiler se você já viu o filme e ainda não leu o livro. ;) Primeiro livro</h4> O primeiro livro conta desde a festa de aniversário do Bilbo até o momento onde está fugindo dos espectros e eles foram levados pelo rio. Entre esses dois eventos muita coisa legal acontece, e muitas coisas que não aparecem no filme por diversos motivos, alguns por quantidade hábil de tempo ( senão o filme seria infinito... ) e outras por que não seria muito legal a cena em filme e apenas em livro é legal. Um personagem que era para estar na comitiva dos Hobbits mas ficou para ajuda-los com o Nazgul foi o Fatty Bolger, que não foi mencionado no filme mas teve a sua pequena participação como amigo dos Hobbits. Uma parte legal que não foi incluída nos filmes foi a viagem pela colina dos túmulos, onde eles encontram algumas coisas legais além de Tom Bombadil (que não faria uma boa participação no filme devido a característica do personagem, apesar de toda a influencia que tem na história e por ser uma das criaturas mais velhas e misteriosas da terra media) que os ajuda. No ponei saltitante que o Sam conhece o Ponei "Bill" que posteriormente é deixado em Minas Moria contra a vontade de Sam, mas ele ainda aparece bastante na história, mas ficou meio de lado no filme. Segundo Livro</h4> O Segundo livro vai desde a chegada a Valfenda até o rompimento da sociedade já com a morte de Boromir. Na minha opinião a personalidade do Boromir ficou um pouco diferente no filme, fazendo com que ele parecesse traiçoeiro todo o tempo, o que no livro da outra impressão, que ele estava realmente indo até Valfenda para descobrir mais sobre os sonhos que tiveram sobre o retorno do descendente de Isildur e os pequenos. As passagens por Moria com charadas para entrar, a queda de Gandalf na luta contra o Balrog, foi como rever o filme com vários detalhes. A passada por Lórien foi muito legal, e é interessante ver as pequenas aparições do Golum em alguns lugares, e os caras tentando descobrir que bicho era aquele que estava rastejando em tal lugar e tudo mais. Terceiro Livro</h4> O terceiro livro conta desde a morte de Boromir e sua partida pelo rio até o momento que Pippin olha no "Palantir". Gostei de ler todas as estratégias dos cavaleiros de Rohan contra os Uruk-hai enquanto eles estavam com Pippin e Merry, até todos os detalhes da fuga deles no meio das batalhas para a floresta de Fangorn. Fangorn é o nome do Barbarvore, que é outro dos seres mais velhos da terra média. Uma coisa que foi interessante, foi que os Ents realmente decidiram ir para a guerra e marcharam para isso, não apenas viram uma foresta devastada e foram do nada ( assim como no filme ), e foi legal ler sobre a marcha deles. Outra coisa interessante tambem são os momentos com Barbarvore que são muito bem descritos, tanto como as tocas dos Ents. As descrições da batalha dos ents em Isengard são ótimas! O que eles fizeram, seus momentos de fúria contra a torre do Saruman e mais coisas interessantes. Uma cena boa de se ler é quando Gandalf (que já tinha retornado como O branco) conversa com o Saruman após o fim da Guerra, quando Isengard havia sido derrotada (que só tem na versão estendida do filme), onde ele mostra que o Saruman já não tem mais cor nenhuma e que o único poder dele era a voz e isso ainda podia persuadir muita gente. Quarto Livro</h4> O quarto livro conta a parte da viagem que fala sobre Frodo e Sam, desde o momento que eles prendem o Golum e ele jura guia-los, até o momento que Sam acha que Frodo estar morto após ser atingido pela ferroada da Laracna. No livro é ainda mais claro como o Sam odeia o Golum e sabe que será traído a qualquer momento, enquanto o Frodo ainda acredita nele ( seja por que achq eu ele vai melhorar ou por que não tem outra escolha ). Aqui que o Faramir aparece pela primeira vez perguntando pelo Boromir, e é aqui que ele quase mata o Golum por estar no lago proibido. As descrições do Tolkien sobre os lugares, paisagens e detalhes de personagens são fantásticas, e você consegue criar mentalmente todo o cenário. Quinto Livro</h4> O quinto livro vai desde a chegada de Gandalf a Minas Tirith junto com Pippin até o fim da guerra de Gondor e a concentração em frente ao portão negro. Gostei bastante desse livro por que detalha bastante a concentração das tropas, os ataques, o medo das pessoas que estão na cidade, e a espectativa pré-guerra. Uma das coisas que eu estava esperando ver e não aconteceu exatamente como eu esperava, era a guerra no Pellenor com o auxílio dos mortos que vieram das sendas dos mortos. Na história original eles ajudaram a tomar todos os navios que estavam indo para Gondor, mas não foram além para ajudar na batalha ( assim como aconteceu no filme ), e foram dispensados antes, portanto, na batalha em Gondor eles tiveram que vencer com homens que conseguiram no caminho com os navios e os que já estavam lá. A morte de Théoden juntamente com o grande feito de Éowyn ( com a ajuda do Merry ) ao matar o senhor dos Nazgûl justamente quando eles tinham acabado de derrubar o portão e ele estava pronto para adentrar na cidade foi muito bom! Vendo as descrições das batalhas achei as cenas dos filmes mais fantásticas do que eu achava antes. Sexto Livro</h4> O ultimo livro começa com Sam indo ao resgate de Frodo que foi levado pelos Orcs até Cirith Ungol e termina com o final das guerras, da terceira era e da influência dos anéis na terra média. Os detalhes das torres e das brigas dos Orcs em Cirith Ungol é muito interessante e você sente o quanto o Sam estaria desesperado por estar dentro da fortaleza do Inimigo numa missão praticamente suicida, mas por sorte os orcs se mataram antes dele chegar...hehe O que gostei mais foi o final que não é totalmente clarificado no filme, e no livro tenho todos os detalhes e o ponto final. A parte final onde se vê todos se despedindo saindo de Gondor e passando por todos os lugares que passaram, deixando cada povo em sua determinada terra, sem contar com alguns que se juntaram para fazer coisas diferentes é interessante como lembrança de toda a história. Agora pude ler todos os detalhes do casamento do Faramir com a Éowyn. Ela é um dos personagens mais interessantes, por que é uma mulher que não quer ser rainha nem donzela, e sim um cavaleiro e lutar até a morte, e o Faramir usou ótimos argumentos para domar a fera...hehe A parte de expurgo do condado que eu estava curioso para ler havia muito tempo, e não sabia que o Saruman ia aprontar antes de morrer ainda. Apêndices</h4> Estou começando a ler os Apêndices agora e eles com certeza serão a minha introdução para o Silmarilion, por que falam muitas coisas que a história conta, e agora entendo o por que de cada acontecimento. Enquanto ele vai descrevendo cada acontecimento ele manda as referências em páginas, tanto nessa obra como em outras como O Hobbit (que eu também tenho), e por isso eu quero degustar aos poucos essa leitura vendo todas as referências e ligando os fatos entre as histórias. :D Eu recomendo bastante você a ler os Apêndices se você quiser entender que O senhor dos anéis é só a ponta do Iceberg num mundo maravilhoso que o criou. Conclusão</h4> O que eu queria fazer é descrever um pouco que eu gostei mesmo de ler, e como não fui anotando nada e deixei para fazer tudo no final, e não lembro de muitas coisas que eu queria escrever aqui, mas acho que consegui escrever alguns dos pontos legais que não tem só no filme. Só para constar, eu acho o filme fantástico e na minha opinião é uma das melhores adaptações de livros ever! As coisas que eu comento aqui não tiram nem um pouco os méritos do filme, apenas mostram que um livro de 1200 páginas pode ser muito mais bem detalhados do que 9 horas (ou 11 no estendido) de filme. Acho que consegui descrever sem dar grandes spoilers para quem nunca leu, e recomendo muito mesmo que você leia, por que vale muito a pena! GameReview: SpiderMan - Friend or Foe Unknown — Wed, 22 Jul 2009 00:00:00 +0000 Aqui estou eu com mais um GameReview de um jogo que eu tenho jogado ultimamente no PSP e finalmente no sábado as 02:15 eu consegui terminar</a>, o Spiderman - Friend or foe! Como quem já me conhece sabe, eu sou um fã de homem aranha! Não aquele fã que tem todos os quadrinhos ou que fica comprando um monte de coisas, mas eu sempre gostei das histórias do aranha e sempre que possível comprava ou pegava emprestado algumas séries de quadrinhos para ler, ou jogos para jogar, ou desenhos/filmes para assistir, enfim... Homem Aranha FTW! :D Agora vamos ao game: História</h4> A história do jogo é bem legal e foi uma das coisas que mais me motivou a jogar. Você é convocado por ninguém mais ninguém menos que Nick Fury ( da S.H.I.E.L.D, veja ele no menu do jogo</a>) para descobrir e eliminar uma espécie alienígena de simbionte parecido com o que é o Venom. Até aí tudo bem, pois seria apenas mais um enredo do Aranha com simbiotes, mas o mais legal disso é que os simbiotes se apossam dos inimigos do aranha, fazendo com que você tenha que enfrentar seus velhos inimigos que estão possuídos por um "amuleto místico" alienígena e libertá-los do controle requisitando a ajuda deles para acabar com os simbiotes que os possuíram. Jogabilidade</h4> A jogabilidade não é tão boa quanto eu pensava, e dá a impressão que o jogo não foi tão bem programado quanto deveria. Durante o jogo você encontra alguns barris para quebrar e conseguir Tokens para comprar novos golpes e tal, mas você só pode quebrar um por vez com socos ( a não ser que você use um Stomp, que só o do Venom é legal... ), e os socos são estranhos para acertar...Sem contar que os combos não são muito claros para sair também, tem horas que vale mais a pena você ficar alternando entre dois botões do que tentar um combo específico. Dificuldade</h4> Achei o jogo muito fácil. Você tem dois personagens para controlar e não há limites de vidas, você pode morrer infinitas vezes desde que haja um personagem vivo no tempo que o outro está morto, e isso torna as coisas muito fáceis por que você pode simplesmente ficar correndo ou usando os "especiais" de defesa enquanto o outro personagem não retorna. Me lembro de ter perdido os 2 personagens apenas uma vez no jogo por bobeira minha. Pontos Fortes</h4> Eu gostei bastante da história e dos vídeos tanto explicativos para a missão como os vídeos pós-missão também. Os vídeos são engraçados e explicam bastante sobre a missão, e tem bem a cara do homem aranha mesmo, olhando para o Misterio e perguntando se ele tem um peixe na cabeça, ou falando que não quer que o Venom ajude...hehehe</li> Os mini-games são legais</li> A espectativa de qual será o próximo personagem que você vai liberar para jogar</li> Suposto final alternativo que eu ainda não vi e acho que vou ter que terminar denovo para saber...hehe</li> Vários extras diferentes para liberar</li> </ul> Pontos Fracos</h4> Definitivamente não gosto de jogos que tem paredes invisíveis no cenário, acho que quando não tem nada para aquele lado não deve haver um espaço para se andar</li> Alguns problemas de colisão chatos acontecem de vez em quando, como você ficar em frente a porta quando ela vai abrir e ela te atravessar</li> Toda vez que você vai encontrar inimigos tem uma cena que mostra os inimigos aparecendo e tal, mas se você estivesse quebrando um barril do outro lado do cenário e os inimigos aparecerem você será "tele-transportado" para um local padrão no cenário para esperar os inimigos.</li> As missões se tornam um pouco cansativas por ser sempre do mesmo jeito, você encontra sempre os mesmos inimigos, alterando pouca coisa nas cores e alguns golpes e sempre as mesmas quantidades com a mesma intro.</li> </ul> Concluindo, para quem realmente gosta das histórias do Aranha ( assim como eu ) provavelmente vai gostar do jogo, mas se você nem gosta muito do aranha acho que você vai achar o jogo cansativo e não vai conseguir ir até o final. No fim das contas....Eu gostei! :) Encontro de numero 5 do Guru-sp Unknown — Tue, 21 Jul 2009 00:00:00 +0000 </a> Nesse sábado aconteceu o quinto encontro do Guru-sp</a>! :) O encontro estava marcado para as 10 da manhã com uma seção para iniciantes e começou as 10:30 ( sempre atrasa um pouquinho né? hehe ), já com um bate papo legal coordenado pelo @rafaelrosafu</a> após uma breve apresentação de todos os participantes. Rails para iniciantes</h4> Nessa primeira seção tiveram muitas conversas interessantes sobre algumas filosofias Rails, como: DRY</a></li> REST</a></li> TDD</a></li> Test all the Fucking Time</li> Skynny Controllers and Fat Models</li> </ul> e mais algumas outras coisas bem interessantes que fomentaram uma ótima discussão sobre quais os melhores padrões para se seguir quando se constrói uma aplicação Rails (sim, falamos tomando como base uma aplicação Rails), como utilizar plugins como o ResourceController</a> (que tem seus prós e contras), manter seus scripts num lugar diferente da pasta scripts, que é a pasta padrão para scripts "internos" do Rails e tentar centralizar em uma pasta dentro de lib, além de usar Rake sempre que possível para essas tarefas ficarem organizadas e de fácil acesso. Uma parada rápida para o almoço no Shopping e lá se vão mais de 20 programadores para comer a bater papo! :) DataMapper</h4> Após o almoço tivemos a palestra sobre DataMapper</a> do @rafaelrosafu</a> (olha ele aí novamente!) que explicou muito bem dando várias referências sobre o seu blog pessoal e como ele fez para utilizar o DataMapper ao invés do Active Record. O Rails é mais difícil de se sair do padrão, mas ficará mais simples de se escolher um ORM quando chegarmos ao Rails 3. Aproveitando o gancho de DataMapper eu falei um pouco de Sinatra dando alguns pitacos na condução do Rafael. Git</h4> Após a palestra de DataMapper passamos para uma palestra de Git com o Douglas (qmx), que foi muito interessante e participativa! Pegamos uma galera do grupo para fazer um scaffold e commitar no projeto para começar a ver coisas diferentes, como merges, rebases, mudanças de commit, e algumas outras coisas legais, como usar tags, procurar por um código em meio aos commits e outras coisas interessantes! =) Levantamos a idéia de participar do Rails Rumble, aproveitando que o Diego Carrion estava conosco e comentou que a GoNow estava patrocinando 3 equipes para o evento, mas não conseguimos ter uma idéia legal para propor para o concurso. Coding Dojo</h4> </a> E finalmente como ultima coisa do dia tivemos o nosso coding dojo, que era uma das coisas que eu mais estava esperando nesse econtro! O Vinicius Baggio "se ofereceu" (com um empurrãozinho meu...hahah) para ficar com o notebook ligado no datashow e conduzir o código. O dojo foi muito divertido com participação de todos da sala, o que sempre trazia novas idéias para fazer um código melhor e agregava conhecimento para todos. Fizemos TDD para construir umas classes simples de usuário. :) Conclusão</h4> Gostaria de agradecer ao André e o pessoal da Voice Technology por todo o apoio ao evento e ao grupo, com local, organização, fotos e mais várias outras coisas! Guys you Rock! :D Infelizmente algumas pessoas não puderam aparecer, e outras apareceram por pouco tempo (o Marcelo Castellani), por motivos pessoais, mas espero que estejam presentes no próximo! :) O evento realmente valeu a pena e aprendi muita coisa por lá, alem de conhecer muita gente interessante tambem! Agora é marcar os próximos e esperar que o grupo cada vez cresça mais e podemos fortalecer as amizades e conhecimentos! GameReview: Diablo Unknown — Mon, 20 Jul 2009 00:00:00 +0000 Pois é... Sei que muitos de vocês devem estar pensando se esse era um review de algum demo do Diablo III que sabe se lá como eu teria conseguido por que ainda nem lançou, mas não, esse é um review do Diablo I! Estranho como um jogo lançado a tantos anos atrás tenha ganhado um review meu agora, não? :P Quando o Diablo I foi lançado eu mal sabia o que era ter um computador, e a única coisa que eu podia fazer era ver um colega meu com o jogo original jogando enquanto eu ficava babando....hahaha...Pois é, e os tempos passaram, eu comprei meu Playstation e comecei a jogar Diablo ( um port da Brasoft para o Diablo do computador, que ficou bem razoável diga-se de passagem ), mas ocupava muitos blocos do Memory card se salvar o progresso no jogo e salvar só o personagem e ir passando toda a história toda vez era muito chato, então não joguei muito apesar de achar muito legal. Quando já tinha meu computador comecei a jogar Diablo II que por sinal é muito legal, mas não é o tema desse review, e talvez algum dia tenha o seu, mas eu não cheguei a terminá-lo. O mais interessante é que eu não conhecia o suficiente da história do Diablo para entender algumas coisas. </a> Pois bem, agora com o PSP, recebo a notícia do meu colega que ele estava conseguindo rodar aquele diablo do Playstation no PSP, e foi só o que faltava para despertar a minha vontade de voltar a jogar esse jogo! :) Dessa vez resolvi adentrar realmente na história do jogo, portanto comecei a ler toda a história em alguns sites e entender toda a trama do jogo (o que por sua vez me fez entender toda a trama do segundo tambem :D). Tinha escrito um resumo da história do jogo, mas resolvi não deixar aqui para que vocês vejam a história completa, por que eu não vou conseguir dar todos os maravilhosos detalhes da trama aqui. Veja a história do Diablo aqui</a> (realmente vale a pena). O jogo em si é muito legal para quem gosta do bom e velho RPG. :) Você pode escolher entre 3 personagens: O guerreiro tem mais força inicialmente e pode brandir machados e espadas mais facilmente, a "Arqueira" (não sei como chamá-la) tem mais abilidade com armas de longa distancia, e o mago vem com um nível de magia maior para você utilizar mais cajado e magias. A diferença nos personagens é apenas inicial, você pode muito bem pegar um mago e aumentar apenas a força dele para que ele possa brandir armas maiores, só vai demorar um pouco mais, assim como o guerreiro pode muito bem aprender magias. O jogo é grandioso para a época, e se passa num cenário fechado dividido por 16 ou 17 níveis, onde você desce por catacumbas enfrentando criaturas infernais e personagens que tem história própria, que só quando você conhece a história do jogo você percebe como a trama foi bem criada. O objetivo do jogo é claro, você tem que matar o Diablo que se soltou da velha pedra que o aprisionava e agora se apossou do corpo do filho do rei Leoric. Ele se encontra no ultimo andar das catacumbas, e para chegar lá você se encontra com muitos passos da história e vai encontrando vários livros que vão lhe mostrando partes interessantes sobre a sua missão. O jogo no PSP (que é o mesmo do Playstation) não é tão rico quanto o do computador que tem muitas coisas bem legais, mas é bem jogável e a jogabilidade ficou bem legal levando em consideração as limitações que eles tiveram que encontrar para migrar um jogo de PC que era controlado por um mouse e tinha diversas teclas para facilitar para um controle com pouquísimos botões. Não encontrei bugs (sei que existe um "truquezinho" para duplicar items e ouro, mas isso não é beeeem um bug :P), e apenas me deparei com alguns momentos de slow down no PSP quando a quantidade de inimigos é muito grande, mas nada que vá atralhar muito a jogabilidade. Concluindo, se você está em 2009 (assim como eu estou agora quando estou escrevendo esse post) e ainda não jogou Diablo I aproveite e jogue! Leia a história do jogo e comece a jogar que você vai entender cada parte do jogo e vai ver como a história é bem ligada, e os personagens que já participaram ainda tem seu papel no meio do jogo, ele lhe dará uma boa introdução para que você se prepare para o Diablo III que vai ser lançado em breve pela Blizzard! o/ </a> E para finalizar esse post com chave de ouro deixo o meu momento de triunfo ao terminar o jogo, onde ele fala que por enquanto o Diablo está contido, mas você não sabe até quanto poderá conter toda essa maldade com você.... E agora....Diablo II mostra sua nova aventura! ;) Pragmatic version control using Git Unknown — Sun, 19 Jul 2009 00:00:00 +0000 Há tempos que eu estava querendo conhecer um pouco mais do Git e nos últimos dias estava procurando um livro legal, quando me deparei com esse livro. Fiz algumas perguntas para um pessoal no Twitter como pessoalmente sobre esse livro, alguns me recomendavam, outros me passavam outros também interessantes, e estava em dúvida entre comprar ou não, até que consegui emprestado e li em 3 dias. O livro é bem interessante, aborda desde o mais básico até o nível intermediário, não abordando conteúdos tão avançados. Começa abordando como é o fluxo de trabalho do git, mostrando com exemplos práticos como você faz para usar o git num projeto, modificando o arquivo, adicionando para o stage, fazendo commits e etc. E fica uma boa parte do livro mostrando um pouco sobre as formas com que você pode fazer as coisas, como: Adicionar arquivos como o git add -i</code> para adicionar interativamente</li> Usar git log -p para alem de ver as mensagens de commit ver tambem o que foi usado</li> git log -2</code> para ver apenas as 2 ultimas mensagens de log</li> git diff --cached</code> para fazer o diff do que já está no stage</li> E mais várias outras dicas úteis</li> </ul> Uma das coisas que eu achei interessante foi a apresentação de curiosidades interessantes como dizer que o Git usa um hash SHA1 que tem uma chance se se repetir de 2⁶⁹ :P. Comentou sobre algumas ferramentas para se usar junto com o Git, como alguns mergetools para facilitar no processo de merge e o git gui ( que é feio que dói, mas funciona ) para quem gosta de brincar com algo no estilo tortoise. Depois de explicar sobre a parte básica do Git ele começa a passar para algo mais intermediário, onde vem os merges e as modificações de commits localmente. Nessa parte mais intermediária foi comentado sobre o git rebase</code> e como você pode usá-lo para reorganizar os seus ultimos commits usando git rebase -i</code>. É uma técnica bem interessante quando se faz um monte de commits locais mas quer enviar apenas um commit para o repositório. Foi comentado tambem sobre tags e como é útil utilizá-las para marcar as versões do seu sistema, sendo que você pode adicionar commits apenas a uma tag e tal. Utilizando git tag 1.0</code> você já define que determinado commit marca a versão 1.0 do seu sistema. Você pode depois dar um git checkout na sua tag e ver ela como read-only (sendo possível criar um branch e fazer modificações). Mais modos do git log foram apresentados tambem, como fazer um git log</code> para ver os commits das ultimas 5 horas, ou desde as 10 horas usando --since</code> ou --before</code>, ou até mesmo usar um --pretty=format:""</code> e passar uma melhor maneira para formatar o seu log. :) Conheci algums comandos interessantes que raramente são usados mas são muito úteis tambem: O git gc</code> que compacta o seu repositório para que ele exclua tudo o que não está relacionado a nada, assim reduzindo o espaço que seu repositório ocupa.</li> O git archive</code> para você gerar um arquivo com seu repositório com a versão que quiser, sendo tag, passando o Head ou o que achar melhor.</li> O git reflog</code> para quando você precisa recuperar algum commit que não está mais no repositório, algo que estava em um branch que foi excluído ou coisas do gênero ( lembrando que se você usou o git gc isso não será possível )</li> </ul> O livro tambem comenta de vários outros comandos, como o git cherry-pick por exemplo, para você passar um commit para outro branch, e sem contar que mostra várias opções que os comandos normais tem, como o git diff para você ver os status a partir de uma tag e tal. Concluindo, achei o livro interessante e recomendaria para muita gente! O que eu tenho a dizer é que ele não é um livro para alguem que quer ver algo avançado em git, e sim alguem que não conhece ou sabe apenas o bem básico, pois assim vai conhecer algumas coisas bem legais. Como desabilitar o beep no Ubuntu Unknown — Thu, 09 Jul 2009 00:00:00 +0000 Resolvi postar sobre isso por que é uma coisa tão simples mas irrita muito quando você não sabe como desabilitar, e sempre que eu procurava eu caia em fóruns com vários comandos bizarros e colocar algo referente ao com no blacklist e não sei o que mais lá que era chato de se fazer, quando é tão fácil. O que sempre acontecia é que eu estava aqui ouvindo boa musica (e alta, por sinal) e programando, o que me levava ao terminal em vários momentos, e quando eu menos espero aquele meu backspace adicional gera um beep monstruoso que dá um grande susto, e isso me irritava profundamente. O caso acima é o caso primário de beep, quando o mesmo é vindo das caixinhas de som, e pode ser desabilitado no mesmo local que o caso secundário. O caso secundário é quando o beep chato vem do seu speaker, portanto mesmo abaixando o som da caixinha você ainda tem o maldito beep lá no speaker. Pois bem, ambos os beeps podem ser desabilitados aqui: System > Preferences > Sound Todas as opções referente aos sons emitidos pelo sistema operacional ficam aí e você pode desabilitar só alguns ou todos (como é o meu caso). E para o beep do speaker é só desmarcar a caixa System Beep! :) Espero que mais ninguém fique desgraçando o sistema por que ele fica emitindo beeps supostamente benéficos para vc! :P Serviços legais de Julho Unknown — Sat, 04 Jul 2009 00:00:00 +0000 Esse mês eu estou conseguindo novamente fazer um post sobre os serviços legais que eu encontrei esse mês ( e alguns que eu já uso faz tempo ) Wakoopa</h4> O Wakoopa</a> é um software que você instala em seu computador e ele lhe dá estatísticas do que você mais usa, entre aplicações desktop e webapps! Mas isso não é o melhor disso tudo! O melhor é que ele se integra com uma conta que você tem no site do Wakoopa e se torna uma rede social onde você pode ver o que seus amigos estão usando, fazer reviews de softwares que você gosta, encontrar softwares novos e outras coisas bem legais! :) Crunch Base</h4> Resolvi mencionar o Chunch Base</a> após descobrir que ele é a base que o Wakoopa consulta para saber o que é e o que não é uma web application. A idéia do CrunchDB é que o conteúdo é colaborativo, mas é moderado, e assim muitas aplicações podem realmente confiar que a base deles é valida. Achei bem interessante o projeto e resolvi até adicionar a empresa que eu trabalho atualmente</a>. Type Racer</h4> O Type Racer</a> é uma web app para criar competições de digitação, e tem me ajudado bastante a melhorar a minha e aprender a digitar melhor e mais rápido do que eu digitava antes. Não precisa ser cadastrado para tentar, mas quando se é cadastrado você tem gráficos nos textos que vc já digitou para saber o quanto progrediu desde que começou a treinar, e ainda uma média de palavras por segundo. Eu realmente recomendo! Queen Alice</h4> O Queen Alice</a> é uma nova versão daquilo que chamavam de "Xadrez Postal", que era quando duas pessoas montavam dois tabuleiros, cada um em sua casa, e sempre que um fazia uma jogada ele escrevia numa carta e enviava de volta para seu adversário, assim quando o mesmo recebia ele fazia sua jogada e o processo se repetia até o final do jogo. Um jogo poderia demorar anos! O Queen Alice faz uma coisa parecida mas usando e-mail, com tempos determinados, portanto você começa um jogo com um amigo já acordando o tempo (1, 3, ou 7 dias jogada) com várias opções legais, e sempre que seu adversário faz uma jogada lá você recebe um e-mail dizendo que é sua vez e vc tem um determinado tempo para jogar senão o adversário pode reivindicar a partida. Tem muitas opções legais e vale a pena para quem gosta de xadrez mas não tem muito tempo para treinar. É isso ae! Quem sabe no mês que vem eu consiga trazer mais serviços web interessantes! ;) Opera Unite Unknown — Tue, 16 Jun 2009 00:00:00 +0000 Hoje é o dia em que o pessoal da Opera falou que iria reinventar a web, e o que eles fizeram foi lancar o Opera Unite</a>! A idéia do Opera Unite é tornar a internet mais interligada, fazendo com que você consiga compartilhar arquivos, conversar com amigos e outras coisas apenas usando o browser. Eu nunca utilizei Opera ( não por que eu sou contra, e sim por que eu nunca precisei e sempre estive confortável com o Firefox, principalmente para desenvolver ), mas achei interessante a campanha de marketing e a idéia deles com esse novo produto. Muitos disseram que isso não era reinventar a web ( realmente fo um pouco de exagero de marketing...hehe ), mas eu acho que isso pode revolucionar muita coisa, só pela nova idéia mesmo! Quem sabe daqui a pouco tempo tenhamos nossos browsers participando bem mais da web. O que o Opera Unite traz</h4> Fridge - Adicionar notas no estilo Post Its</li> Media player - Para compartilhar suas musicas, você apenas ativa ele no Opera e ele abre uma página compartilhada onde você pode apenas clicar e ouvir! =)</li> Web Server - Para compartilhar páginas HTML! É possível criar um index.html e compartilhar ele, assim você terá uma página sendo que seu computador será a hospedagem.</li> Photo Sharing - Para compartilhar os seus albuns de foto.</li> The Lounge - Ferramenta para hosting de um chat, bem interessante por sinal.</li> File Sharing - Para compartilhamento de arquivos ( obviamente )</li> </ul> Todos os serviços são protegidos por senha assim que são disponibilizados para manter a sua privacidade, mas você pode deixar publico se quiser. Os serviços tambem vem desabilitados por default quando você instala o Opera, mas é facil habilitar: Após instalar o Opera você verá no canto inferior esquerdo um ícone parecido com um ventilador, após clicar nele você verá um assistente para criar uma conta no Opera.com e habilitar os serviços no Unite ( é simples ). Considerações finais</h4> Eu gostei bastante da ideia do pessoal do Opera, e acho que traz bastante interatividade para a internet. Talvez aqui no Brasil ainda não seja uma realidade um compartilhamento entre computadores bom usando a internet devido as nossas conexões, que na maioria das vezes não é rápida o suficiente para dar uma boa impressão para o serviço. Parabéns a equipe do Opera pela inovação! :) Instalando modem 3G Claro USB E226 no Ubuntu Unknown — Sat, 13 Jun 2009 00:00:00 +0000 Após receber um modem Claro da empresa que eu trabalho atualmente</a> eu fui fazer o processo de instalação no Ubuntu. Já tinha recebido a informação de um colega de trabalho</a> de como fazer, e obviamente não foi nada difícil (o que que é difícil no Ubuntu? :)). Vou descrever aqui o processo: Inserir o modem na entrada USB</li> Vai aparecer um assistente de configuração simples ( Next Next Finish ), para você seguir e instalar.</li> </ol> Caso o assistente não apareça automáticamente (foi o meu caso), você pode acessá-lo clicando com o botão direito em cima do ícone de rede que fica ao lado do relógio e clicar em "Edit Connections" ou apertar Alt+F2 (ou o seu atalho para executar) e digitar nm-connection-editor. Estando no editor de conexões basta clicar na aba "Mobile Broadband" e depois clicar em "Add", que o assistente vai aparecer. Quando terminar o processo com o assistente ( rapidinho ) o seu modem já estará instalado! :D Para sua internet funcionar você só vai precisar mudar os endereços de DNS que não estarão corretos. Para alterar apenas clique em na conexão que você criou no "Edit Connections > Mobile Broadband", e clique em "Edit". Após clicar em "Edit" digite a senha do seu usuário (se necessário) e siga para a aba IPV4 Settings. Nessa aba altere o campo DNS Settings para 208.67.222.222, 208.67.220.220. Com isso você já vai conseguir navegar normalmente! :) Serviços interessantes Unknown — Fri, 12 Jun 2009 00:00:00 +0000 Depois de conhecer alguns serviços legais na internet resolvi postar sobre eles aqui. Gostaria de fazer um post desse tipo mensalmente ( assim como o Ronaldo Ferraz faz no seu blog</a> sobre o balanço cultural, que eu acho bem legal ), mas pelo menos dessa vez quero postar algumas coisas legais, e se possível eu posto periódicamente o que eu tenho feito / encontrado de divertido. ;) Dropbox</h4> Já começando com o DropBox</a>, que é uma aplicação para sincronização de arquivos. Ele funciona da seguinte maneira: Você instala o software do dropbox (que tem para várias plataformas! ), e cria uma conta no site, com isso eles disponibilizam um armazenamento de 2GB gratuitamente para seus arquivos (e mais no máximo 3 GB se você recomendar alguem, portanto se for criar me peçam um convite please). Com o Dropbox você pode criar pastas compartilhadas com seus amigos que tambem possuem dropbox, assim compartilhando arquivos facilmente, só colocar ele na pasta que o dropbox vai fazer o upload automáticamente e o dropbox do seu amigo vai receber automáticamente tambem. Eu estou usando o Dropbox para compartilhar arquivos de estudos com uns amigos e tambem para sincronizar o meu arquivo do notecase entre o trabalho e minha casa ( assim não preciso ficar colocando pendrive toda vez que for usar o notecase ). Shelfari</h4> O shelfari</a> é uma rede social para leitores de livros! Lá você pode compartilhar suas leituras com os amigos, dizendo o que está lendo, o que planeja ler, o que já leu, fazer resenhas de livros, comentários e mais um monte de coisas legais. Gostei bastante da forma que ele organiza os livros, e o layout de prateleiras é bem legal tambem. Descobri que eles tem um Widget que adiciona uma prateleira ( bonitinha! ) no seu blog / site e é totalmente customizável! Gostei! Vou colocar no aqui assim que eu der uma arrumada no layout do blog. Comunidade Software Livre</h4> Apesar de não gostar muito de redes sociais (para mim fica tudo como redes anti-sociais) eu achei legal a iniciativa de uma rede social para software livre</a>! Seria legal se a grande massa da comunidade estivesse por lá! :) Não tem muito o que comentar pois é uma rede social comum como todas as outras, mas essa tem um foco diferente, que é juntar o pessoal de software livre em um só lugar. ;) É isso! Esses são os 3 serviços que eu achei interessante e gostaria de compartilhar, espero que seja útil para os leitores do blog. Organizando seu Gmail para manter Inbox zero Unknown — Wed, 20 May 2009 00:00:00 +0000 Agora chegando em tempo de provas e grande acumulo de atividades no trabalho eu fico começando a procurar as brechas de tempo que eu gasto "inútilmente" para ver se eu consigo aplicar em alguma coisa que possa me ajudar a cumprir todas as tarefas. Fiz uma pequena análise do tempo que eu perdia em determinados lugares, e vi que tanto e-mail como Twitter me consumiam uma grande quantidade de tempo ( com o Twitter é fácil, só desativar temporariamente e seguir menos gente ), portanto decidi fazer um refactoring! :) Eu uso o conceito de Inbox zero, ou seja, não deixo e-mails pendentes na minha caixa de entrada, mesmo que eu tenha que tratá-los de modos diferentes, portanto eu sempre estou olhando a minha caixa de entrada e me incomoda bastante saber que tenho coisas pendentes lá ( mesmo que seja só para ler ). Depois de contar um pouco do drama, vamos ao refactoring! ;) Listas de discussão</h3> Atualmente eu assino quase 15 listas de discussão, sendo que sou moderador na gtd-br</a> ( sobre organização pessoal com o método Getting Things Done</a> do David Allen</a> ) e em mais 2 listas ( Faculdade e amigos do curso técnico ). Várias dessas listas são ativas e enviam cerca de 3 ( ou mais depentendo da lista ) e-mails por dia, portanto eu tinha cerca de 30 e-mails por dia somente de listas de discussão, fora os e-mails que eu recebia externamente. Uma das medidas que eu sabia que ia me ajudar bastante a manter a organização da minha caixa de entrada e poupar bastante do meu tempo era sair de várias listas que eu participava mas nem acompanhava e colocar todas as que sobrarem como Digest, e foi isso que eu fiz! :D Organizando as labels</h3> Tinha uma grande quantidade de labels que eu não estava usando, ou que criei para uma determinada finalidade e agora não estavam servindo mais para nada, portanto comecei a ver o que me servia e o que não servia para reduzir um pouco o que eu devia organizar. Após retirar as labels que estavam sobrando ( mais ou menos umas 10 ), comecei a incluir alguns prefixos para poder categorizá-las para melhor visualização. Utilizei os seguintes prefixos: [Fr] - Projetos freela que eu participei / participo</li> [Gr] - Listas de discussão ( Groups )</li> [Ps] - E-mails pessoais que eu gosto de Rotular</li> [Wk] - E-mails referente ao trabalho que as vezes preciso receber aqui</li> </ul> Utilizando esses prefixos nos meus labels eu consegui organizar minhas coisas por tema, assim vendo facilmente o que eu tenho de pendências. Organizando os filtros</h3> Agora com as minhas labels arrumadas, preciso gerenciar os e-mails que estão vindo, e para isso eu uso os filtros do Gmail, que encaminham automaticamente os e-mails para suas determinadas labels, já arquivando e fazendo outras coisas. Primeiro criei filtros para as listas de discussão ( que agora vem em formato Digest ) para arquivar diretamente, colocar na label do assunto correspondente e marcar com estrela. A idéia de marcar com estrela foi para resolver um problema que eu tinha antes, que era ter que ficar passeando em todas as labels olhando digest por digest / email por e-mail, e agora como tenho todos os e-mails de digest com estrela, eu posso ler todos de uma vez só e apenas ir retirando a estrela, e ele já estará arquivado, lido e guardado em sua devida label! :) Criei filtros também para os e-mais que eu recebo de fóruns e newsletters para que eu possa ler apenas quando for possível, sem que eles precisem ficar alí me incomodando em tempo integral. Com essa organização eu pude controlar melhor tempo, sendo que todos os dias quando chego no trabalho tenho os vários Digests das listas de discussão que acompanho para ler, mas o processo é rápido e fácil, sendo que vejo apenas os tópicos que me interessam ( baseado no assunto ), e consigo olhar entre todos facilmente, já deixando organizado. Agora sei que posso continuar com a minha caixa de entrada aberta o dia inteiro para enviar e-mails repentinos, sem que isso me tome tanto tempo. Se alguem tiver mais dicas poste nos comentários. Usando Git em projetos do Google Code Unknown — Mon, 11 May 2009 00:00:00 +0000 Resolvi escrever esse post depois de começar a contribuir para o projeto do vimbook</a>, que está no Google Code. Como o Google Code só usa Subversion</a> (infelizmente) e eu sou do mundo Git</a>, resolvi usar a ferramenta Git para lidar com SVN, o git-svn</a>! Com ele você pode clonar um repositório SVN e utilizar como Git, e na hora de "commitar" ele retransforma em SVN. Já havia tentado usar Git-svn no meu projeto de plugin para wordpress</a>, mas nesse caso eu já tinha um repositório Git e fui tentar mandar para um repositório SVN vazio, o que só me deu dor de cabeça, e no fim das contas acabei jogando para um repositório SVN qualquer só para mandar para o Wordpress. No fim das contas, depois desse problema com o Wordpress eu só tinha abominado o git-svn, mas agora eu estou começando a descobrir o seu valor. Meus agradecimentos ao Carlan Calazans</a> que me deu umas dicas de Git-svn quando eu comecei a tentar usar no projeto do plugin, que naquele momento não me fora de grande serventia, mas depois ajudaram bastante! ;) Bem, agora chega de papo-furado e vamos a parte que interessa...Códigos e How To! :) Primeiramente vamos baixar o código ( estou usando como exemplo o vimbook ): git-svn clone https://vimbook.googlecode.com/svn/trunk/ vimbook --username seu.usuario.do.google</code></pre> Ao digitar isso ele vai pedir uma senha que ele gera para a sua conta, e seus commits ficarão ligados a sua conta do Google. Para obter a sua senha é só acessar a página de settings do google code</a> com a sua conta. Após digitar a sua senha ele vai começar a receber todos os commits do SVN e converter para Git! O processo pode ser um pouco demorado, dependendo do tamanho do repositório SVN que você está importando. Quando terminar você terá um repositório Git normal funcionando, e você pode trabalhar normalmente com ele, fazendo seus branchs e tudo mais! :D Vamos ver como seria um fluxo simples para você fazer uma alteração usando branch e mandar de volta para o repositório: git checkout -b new_changes</code></pre> Branch criado! Faça as suas alterações... Após as alteraçoes feitas faça os commits normalmente como se faz no Git e volte ao master para ver o que há de novo no repositório central: git checkout master git-svn rebase</code></pre> Com isso ele vai receber as novas alterações do repositório! Agora é a hora de fazer um merge do seu branch com a ultima versão do master: git merge new_changes</code></pre> Se tiver algum conflito resolva-os normalmente e agora é hora de enviar as suas alterações novamente ao Google Code: git-svn dcommit</code></pre> Pronto! Você está contribuindo para um projeto do Google Code utilizando Git. :D Configurando seu Gtalk do Google Apps no Pidgin Unknown — Sat, 09 May 2009 00:00:00 +0000 Resolvi postar sobre isso depois de passar por 3 empresas que usam o Google Apps for your Domain</a> e eu sempre esbarrar com o maldito probleminha ao se configurar o Pidgin. Pensei que isso era burrice minha de não ver a configuração correta, mas depois percebi que não era só eu que não via essas configurações para poder fazer o negócio funcionar! Como eu nunca anotava o processo, sempre tinha que ficar pesquisando para ver se achava algo relacionado a isso, e nunca funcionava. Quando se pesquisa no Google sobre configurar o Pidgin para usar o IM do seu Google Apps, você geralmente cai nessa página</a>, onde está errado... As configurações corretas para se usar são as seguintes: Aba "Basic": Protocol: XMPP Username: SeuUsuario Domain: sua_empresa.com.br Resource: gmail.com/ ( não sei se é realmente necessário ) Password: ****** Aba "Advanced" Connect port: 5222 Connect server: talk.google.com File transfer proxies: proxy.jabber.org</code></pre> E com isso você já vai ter o seu Pidgin funcionando com a sua conta do Google Apps! :) Ubuntu 9.04 Unknown — Wed, 06 May 2009 00:00:00 +0000 Hoje estou aqui para falar um pouco sobre o Ubuntu 9.04! :) Alguns dias atrás eu postei no twitter</a> que não estava satisfeito com o Ubuntu 9.04, e abaixo descrevo alguns dos motivos. Primeiramente comecei tentando instalar ele pelo cd (para não ter que deixar o computador ligado mil horas baixando, e tambem por que tenho mais de 1 Ubuntu em casa, portanto mais de mil horas x 2) e não consegui.... Procurei várias informações, desabilitei os sources e deixei só o cd lá, e vários outros procedimentos, mas mesmo assim não tive sucesso, e por isso tive que deixar o notebook ligado fazendo download a noite inteira. Ao terminar a instalação e reiniciar ele funcionou beleza! :) Começando a brincar mais com o bichinho, eu descobri que o meu flash tinha bugado (para variar...), e as coisas que utilizavam ele estavam funcionando meia boca, sem contar que ainda tinha alguma coisa bizarra que funcionava como um flashblock</a>, só que pior, por que quando eu clicava ele poderia funcioanar, ou não. ¬¬ Tentei relevar isso, mas quando fui fazer uns testes com o compiz, percebi que ele tambem não conseguia mais ativar os efeitos (tudo bem que eu nem uso... Mas gostaria que funcionasse pelo menos :P), retornando uma mensagem de que os efeitos não poderiam ser habilitados. :( Estava meio sem tempo para perquisar sobre isso, então ficou assim por alguns dias, o que me deu um pouco de desânimo, e foi aí que postei no twitter aquele comentário. Ontem eu resolvi tirar um tempinho para resolver esses problemas, e até que foi simples (como de costume)! ;) Resolvendo problema do Flash no Ubuntu 9.04:</h3> Eu percebi que estava usando um plugin free do flash, e vi comentários na internet que esse plugin não é tão bom como o da Adobe (mas funcionava muito bem no 8.10 :P), portanto resolvi desinstalar e instalar da Adobe: sudo apt-get remove --purge swfdec-mozilla swfdec-gnome mozilla-plugin-gnash gnash sudo apt-get install flashplugin-nonfree</code></pre> E o flash já voltou a operar normalmente! :) OBS: Se não conseguir resolver com o mesmo procedimento que eu usei, veja se consegue com um dos outros 3 procedimentos que tem no UbuntuGeek</a>. Resolvendo problema do compiz no Ubuntu 9.04:</h3> Pesquisando mais sobre o meu problema eu achei esse bug no LaunchPad</a>, com várias pessoas com o mesmo problema, e em um dos ultimos comentários tem uma dica que resolveu o meu! :) A minha placa de vídeo estava na blacklist do compiz, e eu comentei o arquivo, deixando com que ela não fique mais blacklisted: Abri o arquivo do compiz (que está em /usr/bin/compiz</code>), comentei as linhas referente a minha placa de vídeo, salvei e reiniciei. Depois de logar fui testar o compiz, e lá estava ele funcionando novamente! :D É claro que eu já desabilitei os efeitos denovo por que não acho legal ficar trabalhando com eles, mas já está lá funcioanndo para fazer gracinhas! :P Espero que seja útil para mais alguém. Encontro de Design e Tecnologia Digital Unknown — Sun, 26 Apr 2009 00:00:00 +0000 Participei nesse sábado do EDTED (Encontro de Design e Tecnologia Digital), e vou postar as minhas impressões sobre o evento, focando as palestras que assisti: CMS’s livres: não reinventado a roda no desenvolvimento web</h3> A palestra foi conduzida por Paulino Michelazzo da Fábrica Livre, e foi uma palestra interessante! O palestrante soube levar bem a palestra, com momentos engraçados ( várias brincadeiras com Java e Windows, que obviamente não devem ser levadas a sério ), e apresentando como é fácil criar uma loja virtual utilizando o Joomla. O que achei legal da palestra foi ele não focar apenas o Joomla, e sim izer que você não precisa reinventar a roda, e pode usar várias ferramentas para isso como o Drupal, Wordpress, e obviamente o Joomla, cada um para sua determinada finalidade. Crédito para o palestrante: Falou que uma parte do valor que eles conseguem com os projetos eles doam para os softwares livres que eles usam, e isso sim é devolver o que você conseguiu gratuitamente! Parabens a Fabrica Livre</a>. Scrum</h3> Encontrei um amigos como o Ricardo (Guitarrista do Megadriver</a> e programador Web ) e fiquei "networkeando" (ou conversando) por um bom tempo sobre diversas coisas, portanto acabei chegando na metade da palestra. A palestra foi conduzida por Fabiano Milani, em nome da Caelum, e pelo que consegui assistir foi aquele overview geral sobre o Scrum (que eu tambem já tinha visto), e teve uma parte de dúvidas bem legal, com várias pessoas perguntando como poderia implementar Scrum, ou se estava implementando Scrum corretamente, com boas respostas do palestrante. Para quem nunca tinha visto uma palestra de Scrum deve ter gostado bastante da palestra. :) SEO - Search Engine Optimization</h3> Tambem já tinha assistido outras pelestras sobre esse tema, e elas geralmente são iguais, portanto para mim não teve muita novidade. De modo geral, o palestrante Fabio Ricotta da Mestre SEO</a> conduziu bem a palestra, deu dicas interessantes sobre como organizar a sua página semanticamente, mostrou várias ferramentas úteis para utilização em SEO, e várias outras dicas bem interessantes. Uma coisa legal para enfatizar: SEO não é algo que você faz e pronto, e sim algo que deve ser mantido e atualizado com o tempo, pois você não vai ter sempre alta relevância se você aplicou SEO e ficou bem nas buscas, pois isso vai caindo com o tempo, e você precisa continuar mantendo isso com boa semântica. Desenvolvimento web ágil: ferramentas, arquiteturas e princípios</h3> O Guilherme Chapiewski</a> falou sobre muita coisa legal, avaliando linguagens e frameworks como Python / Django. Ruby / Rails, Java, PHP / CakePHPe mais outras coisas. Foi abordado alguns gostos pessoais e experiência própria do Chapiewski sobre as linguagems e frameworks, inclusive algumas considerações sobre Rails e Scala (¬¬), mas a abordagem disso foi com dicas de como poderia ser resolvido de meios diferentes, com problemas que são conhecidos e poderiam ser tratados para ajudar. Ele comentou de 7 métodos que ele usa como um programador ágil: Soluções a longo prazo</li> Sempre pensar no que pode acontecer futuramente. Ele usou um exemplo bem legal sobre um cara que não documentou um sistema por que não tinha tempo, quando futuramente 3 pessoas perderam cada uma 2 dias para entender o que aquilo fazia...Ou seja no fim das contas foi perdido mais tempo do que ganhado nesse caso.</li> Elimine desperdícios</li> Usar um framework que cria tudo facilmente e você pode portar ele facilmente para outras features</li> Qualidade não é negociável</li> Aqui outro bom exemplo...O médico está limpando o paciente após uma cirurgia e o paciente fala para ele deixar isso por que está atrasado para alguma coisa, e é claro que o médico vai te ignorar e limpar, por que ele sabe o que é o certo para se fazer, ele não negociaria a qualidade do trabalho por causa do seu tempo.</li> Não esconda os problemas do cliente</li> O cliente é um cara legal e sua solição simplista pode ser o suficiente para ele</li> Use a melhor ferramenta para cada problema</li> E lá vamos com bons exemplo: Um marceneiro não usaria um martelo para cortar uma mesa sendo que ele poderia usar uma serra para isso. Portanto use sempre o mais adequado para cada situação</li> Documente menos e simplifique mais</li> Foi mostrado um bom exemplo de código, que você olhava e intuitivamente sabia o que ele fazia.</li> Reflita sempre sobre o que você faz e melhore comtinuamente</li> Não fique apertando parafuso para sempre, sempre renove seus conhecimentos.</li> </ul> Os argumentos do Chapiewski sobre Java ser o novo COBOL é bem interessante! Ele diz que o JAVA antigamente tinha ótimos motivos para ser adotado, e assim muitas empresas começaram a utilizar, e atualmente temos sistemas monstros desenvolvidos e vários programadores programando em Java, portanto para sair da linguagem não vai ser tão fácil assim, e foi isso que aconteceu com o COBOL. O Chapiewski falou que só usa Java hoje em dia se tiver um sistema que é obrigado a integrar com Java, por que ele não ve um bom motivo para usar Java, sendo que ele pode usar coisas que ele considera melhor e com mais benefícios. The Rails Way - Como Ruby on Rails pode te tornar um programador pior</h3> O Carlos Brando</a> falou e muito bem sobre o Ruby! Falou muita coisa que eu tinha vontade de dizer sobre Ruby != Rails utilizando um exemplo de miojo e macarronada, como seu o miojo fosse o framework para o suposto cozinheiro! :D Vários exemplos com código para mostrar como o Ruby é parecido com a nossa lingua, e não com a lingua do computador, inclusive usando uns exemplos simplificados do Why. Teve alguns exemplos de metaprogramação para saciar a vontade de quem já conhece um pouquinho de Ruby tambem! :) Gostei bastante da ideia da palestra e o por que de você se tornar um programador pior ( você saindo de uma outra linuguagem que você se considerava bom, para uma outra coisa que você não sabe nada ), e ainda mais mostrando os facilitadores dos frameworks que ajudam você, mas abstrai um pouco da sua felicidade em desenvolver um pouquinho mais low. :P Mercado de trabalho em TI</h3> Foi uma "mesa redonda" com todos os palestrantes, discutindo sobre assuntos sugeridos pelo pessoal que estava assistindo o evento. Foi discutido sobre os valores de trabalho no mercado, apoio as universidades pelo governo, scrum, software livre e outras coisas. Considerações finais</h3> Gostei bastante do evento, consegui conversar várias pessoas legais por lá, como o Caue Linden</a> da HostNet</a>, Maujor</a> do Maujor.com.br</a>, Hugo Borges</a>, Rafael</a> do Ruby Inside</a>, Ricardo que é guitarrista da banda Megadriver</a> (ouça por que é muito foda!), Guilherme Chapiewski</a>, Carlos Brando</a> e mais um monte de gente! O Evento foi muito legal quanto a palestras e networking! Quem não foi perdeu! :D Começando a falar de Ruby Unknown — Mon, 13 Apr 2009 00:00:00 +0000 Se você já conhece Ruby, ignore esse post! A idéia do post é mostrar um pouco da linguagem Ruby para pessoas que não conhecem nada sobre ela. Eu, claro, acho muito interessante que muita gente por aí ainda não conhece Ruby, mesmo com a grande popularização do Rails, e eu chego a ouvir coisas assim: "Não é você que programa naquela linguagem esquisita?" </blockquote> Cheguei a ouvir do meu "professor de algoritmo" (perdeu meu respeito): "Gostei desse algoritmo que você fez nessa linguagem esquisita aqui" </blockquote> Há muitas pessoas que já ouviram falar em algo relacionado a Ruby apenas quando leram alguma coisa na Info falando de RubyOnRails. Portanto, resolvi escrever alguns posts sobre a linguagem para passar para esse pessoal que ainda não conhece nada. Pretendo que esse seja o post introdutório de vários capítulos passando por partes interessantes da linguagem. :) Então...Vamos falar de Ruby! :)</h3> Ruby é uma linguagem interpretada, criada pelo japonês Yukihiro “matz” Matsumoto</a> e liberada publicamente em 1995. Desde lá o Ruby vem aparecendo bastante no mundo de tecnologia, sendo que a partir de 2006 teve um grande boom de comentários, ainda mais com o maior aparecimento do Rails</a>. Uma coisa que me irrita bastante é as pessoas associarem diretamente Ruby com Rails, portanto preciso deixar isso claro... Rails não é Ruby! </blockquote> Rails é um framework para desenvolvimento web que utiliza a linguagem Ruby para o tal. O Ruby tem bem mais coisas legais do que só o Rails. ;) Como o Ruby é uma linguagem interpretada, podemos facilmente fazer um Hello World em Ruby: puts 'Hello World'</code></pre> Isso aí! Apenas uma linha! Uma linguagem totalmente orientada a objeto e você não precisa necessáriamente criar uma classe, um método ( public static void main... ) e escrever mil comandos Hierarquicamente para escrever algo! ;) O interessante do Ruby é que tudo é um objeto, ou seja, se você escreve o numero 10 ele já é um objeto, tendo seus próprios métodos, como por exemplo: 10.times { puts 'Vou estudar Ruby' }</code></pre> No caso acima usamos um dos métodos do 10 (que é da Classe Fixnum) que é o método times, que faz um loop 10 (ou qualquer outro numero Fixnum que estivesse aqui ) vezes fazendo o que está dentro do bloco, no caso, imprimir "vou estudar Ruby". :) No Ruby você consegue modificar métodos em tempo de execução! Uma classe que não possuía nenhum método pode possuir 10 em tempo de execução bastando que seu código os inclua lá, e isso é uma coisa muito legal! A sintaxe da linguagem foi feita para ser simples, você tem vários métodos facilitadores, inclusive com uso de "?" ( interrogação ) para alguns métodos, como por exemplo para descobrir se a variável está não retorna nada: variavel.nil?</code></pre> Aqui temos uma pergunta explícita, que você olhando isso intuitivamente lhe vem duas respostas: Sim ou não ( nem me venha com talvez :P ),o que mostra que você olha um código Ruby e facilmente distingue muita coisa. E tem bem mais coisas</a> interessantes</a>! Tá...E por que diabos eu deveria usar Ruby</h3> Aí que está! É aí que entram as coisas legais, como: Rails</h4> Agora sim você pode usar esse cara aí em cima para desenvolver aplicações bem legais usando todas as facilidades que o Ruby pode te oferecer Shoes</h4> Uma biblioteca bem interessante para desenvolvimento desktop multiplataforma, onde você consegue fazer muita coisa legal. JRuby</h4> Olha que legal, se você gosta bastante do Java, você pode rodar programas Ruby em cima da maquina virtual Java, o que é bem legal, até por que, a velocidade do JRuby, já passou a do MRI ( Matz Ruby Interpreter, ou a versão core oficial do Ruby, feita pelo Matz ). Inclusive você pode importar várias bibliotecas do Java e tudo mais. ;) Iron Ruby</h4> Você usa a plataforma .NET da Microsoft? Então procure por esse cara! Eu não tenho muito a comentar por que não uso .NET. É claro que não existem só esses aí em cima, apenas estou citando algumas coisas legais, mas se você procura por desenvolvimento web você pode escolher Sinatra</a>, Merb</a> (ainda não se fundiu com o Rails, mas isso vai acontecer na versão 3 do Rails), ou outros. E se você apenas pensa em desenvolver para Desktop, alem do Shoes, você pode escolher, o RubyGTK</a>, o MacRuby</a> (para usuários MAC) ou até o FXRuby</a>! Se você não é programador, e trabalha com administração de sistemas, por que não utilizar Ruby para automatizar as tarefas? É fácil, tem manutenção simples, vem padrão em várias distribuições Linux...Não tem desculpa! :P Meu foco nesse post não é abordar a fundo nenhuma das ferramentas que eu citei acima, e sim apenas dar um overview de tudo que você pode fazer usando essa linguagem. Puxa, gostei! Como usar?</h3> Moleza! Está no Linux né? Se estiver usando Ubuntu só dê os comandos mágicos: sudo apt-get install ruby irb rdoc</code></pre> Não está no Linux? Humm...No Windows é fácil tambem, baixe o executável e instale. Não tive muito contato com um mac ainda para instalar coisas e tudo mais, mas me parece fácil. Basta clicar aqui</a> e pegar os arquivos necessários para a instalação! :D Vixe...Instalei, e agora?</h3> Agora é hora de brincar um pouco com a linguagem para saber como ela funciona! Eu recomendo você a entrar no IRB</a> (Interactive Ruby Shell) e começar a brincar! Para acessar o irb é aquela moleza de sempre, apenas entre no terminal e chame por irb ( acho que funciona assim no Windows tambem )! :D Lá você pode tentar executar uns códigos, inclusive os poucos exemplos que eu postei aqui, é muito legal para você conhecer a linguagem, descobrir uns métodos e tudo mais. Já estou no IRB, mas eu não sei fazer nada...</h3> Bem, agora é partir para as cabeças! :D Eu recomendo você a começar lendo o tutorial de Ruby do TaQ</a> que é um material bem legal para começar.</li> Se seu ingles é bom (não precisa ser fluente, mas você precisa saber ler e enteder) eu aconselho firmemente você a participar de algum curso Core do Rubylearning.org</a>, e lá você vai aprender bastante coisa, alem de se divertir bastante.</li> Leia alguns dos livros gratuitos que estão disponíveis na web gratuitamente e em português! Eu recomendo o Aprenda a Programar</a> e o (comovente) guia de Ruby do Why</a>. ( obrigado pela dica Abraão</a> )</li> Participe de Grupos de usuários para aumentar seus conhecimentos e conhecer pessoas que tambem estão interessadas na linguagem e sempre estudando! Se você está em São Paulo eu recomento fortemente você a participar do GURU-SP</a>! :)</li> Fique de olho aqui no blog que eu pretendo começar a postar umas coisas básicas, mas não espere somente por mim e já inicie seus estudos! ;)</li> </ol> Bem, com isso você já tem uma pequena base do que é o Ruby ( e sabe que o Rails é apenas um framework feito em Ruby ) e já pode começar a se divertir com ele! :D Plugin para WordPress: Anti IE6 Army Unknown — Sat, 11 Apr 2009 00:00:00 +0000 Estou postando para anunciar que foi lançada a versão 1.0 do meu plugin para Wordpress chamado anti-IE6-army</a>! :D A idéia do plugin é juntar um exército de campanhas contra o Internet Explorer 6 que estão perdidas pela internet em um único plugin, para que todos que possuem blogs com Wordpress possam usar facilmente, sem precisal alterar HTML, ou abrir qualquer arquivo de código! Aqui no blog tem uma página só para falar do Plugin</a>, e lá você pode obter mais informações. Espero o comentário de vocês sobre o Plugin, e se quiserem contribuir com código, o projeto está no GitHub</a>! :) Esse foi o meu Call to Arms, agora espero que vocês realmente usem! ;) English Version I'm posting here to announce my anti-IE6-army</a> Wordpress Plugin! :D The idea behind this project is unite a lot of campaigns against Internet Explorer 6 that are splitted on the internet on one single wordpress plugin, so everybody with a Wordpress blog will can use it easily, without change any HTML, or open a single code file! You can read more about this plugin on the plugin page at this blog</a>. I'm waiting your comments about the plugin, and if you want to contribut with code, the project is on GitHub</a>! :) This post is my Call to Arms! Now i hope you really use this plugin. ;) Translated Rubylearning presentation Unknown — Fri, 10 Apr 2009 00:00:00 +0000 As I promised, here goes my presentation! :) Finally i finished to translate all the presentation! Watched the video a lot of times, pausing and playing to write all I said translating to english. :) Fortunately I had a big help from my friend Victor Goff</a>, that corrected all my grammar errors and typos. I'm posting below all i have about the presentation, slides from Slideshare</a> and a translation pasted here, but you can find the translation at Google Docs</a> too. Enjoy! :D </iframe> First Words</h3> My name is Willian Molinari as Marcelo said, I participated of 3rd Batch of Rubylearning at the beginning of the last year. Since the finish of the course I was an Assistant Teacher, and i'm a Mentor since the beginning of this year. I attempt to show to you a bit of what Rubylearning is and how does it work, what is the course idea. It is a short presentation, you will see that I'll "run" with the content, but the presentation idea is to show you a bit of what RubyLearning courses are. Slide1</h3> Fist, lets start with "What is Rubylearning?" The course itself is Rubylearning.org, and Rubylearning is divided into Blog, Website and courses. Blog is where Satish post some of his interviews with Ruby community guys like Matt of Merb project or Dr. Nic. And on blog have other cool posts too. On Website Satish maintain a Ruby tutorial, a Ruby Book and post other ruby contents. And on Rubylearning.org the course happens. Slide2</h3> To answer the question "What is Rubyleraning.org" I was helped by the other teachers of Rubylearning. One of the good answers was made by George Thompson, this guy that you see in the large photo. After telling a funny joke, saying that Rubylearning is for everything since it will "allow you to grow wings to fly" and will "help you in the bedroom" He gives these topics to speak about. The first thing is that Rubylearning is for everyone that has an interest in Ruby, if you are a experienced professional, or just learning now, Rubylearning is here to help you. It is a framework to your first steps with Ruby, so you will not depend just from Google or online tutorials, on Rubylearning you will have more people to help you to participate and discuss your answers and so on... Rubylearning is not just for who are starting with Ruby. If you work with Ruby for a long time, you can participate to help the students that are starting, returning to the community what you received. And you can participate with other Rubylearning intermediate courses (Rubylearning doesn't have just the Core course, we have other courses for those who already have knowledge of Ruby) And of course...Rubylearning is a place to have fun! To code for fun, to know different people of other countries, or maybe of your country, and you didn't know that this person was programming on this language. Slide3</h3> Rubyleraning is based on Moodle, as you can see, the image is strange here, but the first screenshot is the screen after you sign up, and you can see all the courses that you can subscribe to, and below you can see the screen inside the course, all the material is divided by blocks, the forums and so on. Slide4</h3> More interesting informations about Rubylearning: We are the declared winner of shorty awards in education category. Unfortunately we couldn't participate of ceremony in USA because only Satish can participate in the ceremony, and the price to travel from India (Satish is Indian) to USA could not cover the costs...But anyway, we are the winners! The number of participants get over 7200 mark, and maybe now we already pass the 7500 mark, because this information is from 1 month ago, more or less. Another cool thing, more than 40% of Rubylearning participants are from Brazil, so you don't have arguments to say: "I can't participate, because the course have people that from other countries and i don't speak english very well", because always you will find a Brazillian to help you there. Slide5</h3> And who is the main teacher? Who is behind Rubylearning? Slide6</h3> Satish Talim, as I said, lives in India. He is a programmer, teacher, consultant, working on some companies at India and USA, is speaker and has more than 30 years of experience with I.T. He has these two domains: Rubylearning.org and rubylearning.com. On .org domain we have the course and on Rubylearning.com is his site. And he have a personal website domain, too. Slide7</h3> Ok, if Satish is behind Rubylearning, who are these guys that help on forums? So... I asked to Satish by e-mail, because I didn't know about how he divide us. The assistant teachers are people that come from the core course and enjoyed the course, so they are invited to help, and whomever accept comes as assistant teachers of the next core course to help on foruns, answering the students that are having doubts and helping on other things. Mentors are experieced professionals that are working with I.T for a long time and more time on Rubylearning, too. They help not only on Core course, but on the other courses ( intermediate courses ) too. The Patrons, this guys are on Rubylearning since rubylearning is coming to be international, on the 2nd batch more or less, on the last months of 2007, and they have more time on rubylearning, so the way that Satish has to classify teacher is time on rubylearning. Slide8</h3> For who is this course appropriate? Well... Our focus is the people that already know something about programming, some other language and wants to know Ruby, and not those people that do not know how to program and want to learn on Rubylearning, This is not our focus. Our focus is to teach Ruby for who those have a notion about programming. Slide9</h3> How does Rubylearning work? Well...The course is slotted into weekly study material blocks. Every Saturday, Satish posts different sudy material with important notes, so you can review quickly all you already read; Some exercises, 10 or 5 exercises depending on how extensive is the material, for you to solve and post on forums, to view the answers of teachers too. For example, you have a method and you are using return to return the variable on the PHP style for example, but can be other language, so somebody replies to you saying that you don't need to specify this return because the Ruby language returns the last statement by default, and so on... The Quiz, is for your own benefit, so you can see if you learn all the content. And the Extras! The extras take to you some good material as links to good content, a screencast related to the weekly study material, and others! Slide10</h3> How do quizzes work? As i said, Quiz is for your own benefit. A lot of people are questioning me about the importance of quizzes on the course participation, "if we don't answer the quiz, are we kicked out of the course" or we don't receive the certificate. The quiz idea is auto-validation, so after you read all the content, you will know with the quiz if you really learn all you need to learn about that content, if you got a good result with the quiz, you probably really learned this weeks content. Slide11</h3> Is necessary be active on Foruns? Humm...Yes! The main focus of Rubylearning is the participation of everybody, so, if you really want to get the best of the course you must to post your exercise answers, to receive from more experienced people feedback about your solution. If you don't participate so much.. it's okay too...You just lost the chance to learn more and more. Slide12</h3> This is one of the things that everybody speaks about..."Ohhh...The course is in english, from India, i will talk nonsense words, i don't speak english, my english is bad"...Humm...My personal English, i'm a assistant teacher, is not so good, but i can communicate with others! If you can communicate with other people is good enough! You will read and understand the content and post your code on forums, if you are not comfortable to write english, you can just post your code, somebody will reply to you, you will understand the reply and it is good enough to your learning. If you can talk is really better, because you can help on discussions, but the english is not a big barrier to participate of Rubylearning. Slide13</h3> How is the course pace? As i said, Satish does weekly content posts on forums...Not forums...the study materials. You don't need to follow this weekly pace, if you decide to view all the course in the last week you can, but we recommend you to follow weekly because you can talk with other people that are studying the same lesson and you have more focus on your studies making it easy to learn different things. Slide14</h3> What topics the course cover? Well...We cover all the Beginning with Ruby, from Ruby installation through... Slide16</h3> basic classes like numbers, blocks, variable scopes, constants, methods, manipulation of text files, Regular Expressions, but only the basis of Regular Expressions, how to work with RE with Ruby, working with classes, inheritance, exceptions... We can't cover tests (the Ruby test/Unit class) on the core course just a bit of it, we want to create a course just to cover test/unit itself, so it is not a core part of Ruby in this course. Slide17</h3> Other questions that are often made to me when I recommend Rubylearning couse is: "I will receive a certificate?". The important thing on the Rubylearning course is how much you can learn with the course, the certificate is not the course focus, but...The answer is YES! Slide18</h3> This is my certificate from 3rd Batch that i participated, really beautiful, signed by Satish, you receive in PDF, is not received in paper, but you can print and store. Slide19</h3> As i said, Rubylearning is not made of only the Core course, we have a lot of other courses that we call the "Intermediate courses", and is appropriate to who that already have a notion of what is Ruby core, if you know core, you can move on to these other courses. Slide20</h3> The merb course, now merb team are joining Rails team, maybe this course will be extinct, but this is one of our courses for now. Git / GitHub is a course of one week. Git is not directly connected with ruby, but all the Ruby community are using it, so we decided to prepare a course about it. Ruby with database, using MySql and sqlite, you learn on how to use activerecord to manipulate a database from a script Ruby. FXRuby as Marcelo said in another speech. Sinatra for web development, maybe will get the Merb course place, because Merb and Rails will be one. Shoes, as Marcelo said too, for Desktop development, very interesting. Ruby and Twitter, is a course that will be released now, i don't know when it will start, maybe april 14th or 16th, for who those already have a ruby knowledge, will be very interesting. They will show how to play with "Twitter API" and make some interesting things with it. And Rails 3, Satish promised that when Rails 3 is comming out he will create a course about it to everybody. Slide21</h3> This is some screenshots of shoes course. The application of the screenshot on the Right was made by Satoshi, that was the main teacher of Rubylearning shoes course, and is is a clock that show all the assistant teachers and mentors timezone on the world, all teacher have a photo placed on with their timezone. I asked Satoshi to send a message to all of you, and he sent to me a message with a "Google translation" Phrase in portuguese saying "Oi todo mundo" that probably is "hello everybody", and he says that you don't need to care about your english because we can communicate with Ruby, and he wants to see you on Rubylearning Forums. Here you can see other screenshot of a little game that they do with shoes, each student have your own game, you can see a "questions and answers" game on the next screenshot. Very interesting and a lot of fun! Slide22</h3> Here you have a message from Satish Talim, i asked to him to send one, and he is saying thanks to all Brazilian friends, Locaweb and Fabio Akita, that are sponsors of the course, the locaweb is a Sponsor of the core course, and saying thanks to you that are helping to spreading ruby around the world. Slide23 - Questions</h3> My presentation idea is to be very quick, just to show to you a bit of what is Rubylearning and how you can participate, what you will learn and so on... Somebody have some question? Hugo: This courses that you show, all of them are free? Or have some paid courses too? Willian: Yes, the core course is free. The other courses you need to pay to get in, but the cost is very low, something like 5 dollars, 3 or 5 dollars, just to maintain the website, Satish put a lot of his time on Rubylearning, so he need a way to maintain all of this, and he is making it with this paid courses and some sponsors, but is not high price, just 3 or 5 dollars with paypal. Some other question? I trampled some content because I have little time. Marcelo: Lets thank Willian, no more questions now... slide23</h3> Thanks! =) Rails X Django Unknown — Wed, 08 Apr 2009 00:00:00 +0000 Como todos sabem eu sou do mundo Ruby/Rails (Não sou xiita mas é o que mais gosto) e de vez em quando começo a brincar com coisas diferentes para poder formar a minha própria opinião sobre o assunto. No mes de fevereiro me surgiu um projeto bem interessante para trabalhar</a>, pessoas legais, oportunidade legal, bem interessante! O projeto seria feito em Python/Django, e achei bem interessante a idéia de poder comparar várias coisas do Rails com o Django. Bem...Vamos as minhas comparações: Pontos fortes</h3> Como primeiro argumento, e incontestável para mim, tenho que dizer que o admin do Django é muito legal! Você consegue fazer coisas bonitinhas e funcionais com uma facilidade espantosa! Sei que no Rails podemos fazer um scaffold ( ou até usar o ActiveScaffold, mas não é tão bom ) e criar facilmente um CRUD para mexer nos dados, mas isso não é um admin pronto, é apenas uma forma fácil de se manipular os dados. Penso eu que com o Rails seja mais facil de se criar um admin personalizado, com Design próprio, mas gostei bastante da solução a curto prazo do Django.</li> Achei bem interessante como podemos fazer a divisão de trabalhos com o nosso HTML(er) / JavaScript(er), por que o Django dá pouquíssima liberdade para o template com relação a código, ou seja, você define na sua view as query's que vão ser mandadas para o template e no template ele vai usar apenas o que você pode mandar, e não vai poder consultar ou fazer maiores alterações no conteúdo, portanto, quem deve cuidar de como o conteúdo vai chegar ao template são os programadores que vão enviar os dados para quem vai fazer a integração com o layout.</li> </ul> Pontos fracos</h3> Não encontrei uma padronização / centralização para os plugins do Django...Você encontra vários modos de instalação para determinados plugins, alguns vem com setup.py, outros falam para você jogar na pasta do Python. Não tem algo centralizado como as gems do Rails ou os próprios plugins para jogar na pasta vendor/plugins, ou usar um script/plugin install ...</li> Não cria uma estrutura de pastas, deixando que você faça o que bem entender com a estrutura, ao invés de usar uma convenção sobre configuração.</li> Talvez seja a inexperiencia, mas eu não achei legal o que tivemos que fazer com o settings, pois cada um precisava colocar uma configuração diferente de diretórios de imagens, ou algumas configurações referentes aos plugins ( filebrowser no caso ), portanto cada um tinha que ter um settings.py diferente, informando o settings.py quando vamos executar alguma coisa.</li> Não me acostumei muito bem com o esquema de indentação do Python...Não que seja ruim, mas como estavamos trabalhando em sistemas operacionais diferentes de vez em quando aparecia um indentation error por causa de conversões de tabs em espaços e tal. Sei que esse argumento vai ser facilmente contestado com um: "É só configurar o seu editor de texto" ou "usa um editor de texto multiplataforma", mas mesmo assim...A idéia da indentação é legal, mas ainda me atrapalha um pouco.</li> </ul> Bem, é isso! Essas foram as minhas primeiras impressões do Django, como disse, não tinha experiência com o framework e muitas coisas poderiam ser evitadas mais facilmente, ou feitas de um modo bem melhor. Continuo gostando bastante do Rails, mas achei muito legal várias idéias do Django, e acho que tem aplicações legais dependendo do projeto que você for usar. ;) Ruby e Rails no mundo real Unknown — Tue, 07 Apr 2009 00:00:00 +0000 Como muitos leitores do Blog sabem, eu palestrei no Evento "Ruby e Rails no mundo real</a>", e vou fazer um pequeno overview desse evento que eu havia divulgado aqui no blog</a>: O evento foi bem interessante, bem alem do que nós havíamos planejado nas primeiras conversas do primeiro encontro do GURU-SP</a>, e atendeu bastante as nossas expectativas por ser o primeiro. Obviamente cometemos alguns erros que vamos melhorar no próximo, como garantir que tenha Wi-Fi por exemplo! :) Quanto as palestras, tivemos palestras interessantes, sendo a maioria delas de um grau não tão técnico como alguns estavam esperando, mas quem sabe no próximo planejamos algo mais hard para mostrar. ;) Eu palestrei sobre o Rubylearning e acho que me saí bem, não foi a melhor palestra do evento (nem de longe...heheh) mas acho que consegui passar o que eu gostaria para a galera, espero ver mais pessoas lá no Rubylearning</a>! Para quem estiver afim de ver como foram os Slides pode dar uma olhada na versão em inglês que eu postei para mostrar para o pessoal do Rubylearning no Slideshare</a>, e se alguem que não recebeu a apostila com os Slides quer ver a verão em português é só pedir que eu posto tambem. :) O agaelebe</a> gravou todas as palestras e assim que possível vai disponibilizar para os que não foram (e para os que foram e querem revisar algo). Criamos uma página no GURU-SP.org</a> para divulgar todas as informações sobre o evento, portanto se quiser saber qual foi a grade de palestras, ver as fotos e ver os vídeos ( assim que estiverem disponíveis ) é só acessar! Projeto de fevereiro Unknown — Fri, 03 Apr 2009 00:00:00 +0000 No mês de fevereiro eu estive envolvido com um projeto bem interessante na empresa que estou trabalhando</a> (ainda vamos trabalhar mais em nosso site 😛), que foi feito em Python / Django e deveria gerar páginas estáticas ( exigência do projeto ). Tivemos um prazo muito curto para tudo que deveria ser feito, o que gerou uma grande quantidade de trabalho fora do horário e dos dias comuns. Entre o começo e o fim do projeto, tínhamos o carnaval, portanto tivemos que deixar nossos espíritos carnavalescos</a> guardados e partir para o trabalho árduo no feriado até horas indeterminadas. O ambiente de trabalho era bem legal, trabalhamos onde chamávamos de The Rubens, que tinha tudo o que precisávamos para nos sentir a vontade: </a> </a> </a> Obviamente nada melhor do que instrumentos (para uma leve descontraída antes de voltar ao trabalho árduo), pessoas motivadas, barrinhas de cereal, livros (vários nomes interessantíssimos nessa biblioteca!) e programação! A única coisa que não tínhamos era tempo o suficiente para fazer tudo tranquilamente, mas aproveitamos bastante o tempo. </a> Trabalhamos todos os dias durante o carnaval, sábado, domingo, de madrugada, e em qualquer outro horário que fosse possivel ( hehe ). Nosso repositório Git já estava bem legal no gráfico de Network do GitHub, entre emaranhados coloridos! Durante o caminho tivemos que enfrentar alguns contratempos, como o calor infernal, a falta de energia elétrica, a quantidade de novidades para lidar, tanto com o Python / Django, como com o Git e outras coisas mais! </a> Nenhum dos contratempos pode nos barrar muito! Com o calor vieram os ventiladores, com a falta de energia veio o nosso local de trabalho provisório (só durante aquele dia), e o prazo curto nós conseguimos vencer com muitas barrinhas de cereal e horas de trabalho. Ahhh! É claro que no meio de toda a correria tinhamos que ter tambem o nossos momentos de descontração, alem do nosso amigo Darth Vader que aparecia na hora dos conflitos do merge… hehehe Entre nossas descontrações (geralmente pouco antes de ir embora, 22:00h) tinhamos sessão violão e Sitar, ou momento Guitar Hero, ou jogo de alvo + dardos, um pouco de tiro com o Open Arena</a> entre outras coisinhas. Estavamos trabalhando com 2 Macs, 1 Windows e 1 Linux, portanto sempre tinha as boas e velhas conversas sobre o melhor sistema operacional, que é claro que o Linux é o melhor (haha, pelo menos aqui eu sou o root para dizer isso… hehehe). Enfim…Foi um projeto corrido, dormimos pouco, trabalhamos muito, consideramos feriados e finais de semana como dias normais de trabalho, mas…Como diria o Rubens</a> (algo parecido com isso): É dos projetos mais difíceis que ficam as suas ótimas recordações </blockquote> Portanto, na minha humilde opinião, se você tiver a oportunidade de entrar naquele projeto difícil com bons amigos, faça que vai valer a pena! :) Update: Bem lembrado pelo Nelson! Nós temos o nosso vídeo de comemoração, quando terminavamos nossas features: </iframe> Ruby Inside Brasil Unknown — Tue, 31 Mar 2009 00:00:00 +0000 Há um tempo já que eu deveria ter postado sobre o Ruby Inside Brasil</a>, mas estou esvaziando aos poucos o meu Todo List e estou aproveitando a promoção que eles fizeram</a> para liberar esse post tambem. :) O Ruby Inside Brasil é a edição autorizada do Ruby Inside</a> mantido pelo Peter Cooper</a>. Uma ótima iniciativa para postar bom conteúdo em português. A idéia inicial do projeto foi do Carlos Brando</a>, que junto com vários outros colaboradores</a> está contruindo o nome do Ruby Inside Brasil, e tem como idéia não apenas postar traduções dos conteúdos do Ruby Inside em inglês, mas tambem postar conteúdo próprio escritos por desenvolvedores brasileiros, cobrindo tudo que acontece relacionado a Rails e Ruby aqui Brasil! Ajude a divulgar o projeto no Twitter, postando em seu blog, falando para os amigos e tudo mais. Se você possui uma empresa e quer patrocinar o projeto entre em contato com os responsáveis pela página de contato</a>. Parabéns a todos envolvidos no projeto. 😉 Colocando sua aplicação Rails na Dreamhost Unknown — Wed, 25 Mar 2009 00:00:00 +0000 Estou fazendo um pequeno site em Rails e como tinha que mostrar o andamento para um colega, aproveitei para testar como seria o Deploy desse projeto na DreamHost ( mesmo sabendo que o provedor final não será lá ), e achei muito fácil de se fazer, portanto resolvi escrever um pouco sobre o processo. :D Primeiramente, você precisa ter acesso SSH na sua conta. Se você ainda não tiver esse acesso apenas faça o seguinte procedimento: Acesse o menu Users > Manage Users</li> Clique em Edit no user que você vai usar para o acesso SSH</li> Marque a opção Shell account - allows SFTP/FTP plus ssh access.</li> </ul> A partir daí você pode acessar por SSH assim como acessava por FTP, com esse usuário e senha. :) Agora que temos acesso SSH a conta, vamos colocar nossa aplicação lá! Se ela estiver no GitHub você pode fazer um clone da sua aplicação facilmente: git@github.com:usuario/projeto-qualquer.git</code></pre> Se não estiver no GitHub você pode fazer um pacote tar.gz e enviar facilmente por scp: tar cvf app.tar.gz aplicacao-quaquer/ scp usuario@xxx.xxx.xxx.xxx:/home/local/da/applicacao app.tar.gz</code></pre> *Sendo que o xxx é o endereço IP ou Nome da sua maquina na Dreamhost Com nossa aplicaçào lá, vamos criar o nosso domínio ou sub-domínio no painel de controle da DreamHost</a>, pelo menu domains > manage domains. Geralmente seu domínio demora um pouco para começar a funcionar, mas você não precisa esperar que ele esteja totalmente funcional para que você continue o processo ;) O que você precisa fazer é: Ativar o Ruby on Rails Passenger (mod_rails)</li> Apontar o Specify your web directory para o diretório public da sua aplicação</li> </ul> Agora que temos o nosso domínio criado e validando ( lembre-se que não é instantâneo ), podemos configurar o nosso banco de dados! Acesse o Manage Mysql</a> pelo menu Goodies > Manage Mysql e preencha o formulário que está logo abaixo dos bancos de dados já existente ( se houver ) para criar um novo banco. Com o novo banco de dados criado, vamos adaptar nossa aplicação para usá-lo! ;) Vá no arquivo config/database.yml</code> e altere as informações da seção production para o que foi configurado no painel.. Agora com tudo configurado, vamos rodas as nossas migrations para as configurações de produção: RAILS_ENV=production rake db:migrate</code></pre> Com isso você já terá seu projeto funcionando assim que o domínio se propagar! Foi bem mais simples do que eu pensava, como eu deixei o repositório com Git lá, basta eu fazer as alterações localmente e dar um push que já terei minha aplicação alterada lá! :) É isso aí, espero que seja útil para vocês. Show do Iron Maiden Unknown — Tue, 17 Mar 2009 00:00:00 +0000 Fui ao show do Iron maiden nesse domingo dia 15/03 e resolvi postar as minhas considerações. O show do Iron Maiden em si foi muito legal! Tocaram muitos clássicos como: Fear of the dark ( der... )</li> Wasted Years</li> Aces High</li> The rime of ancient mariner</li> Phanton of the Opera</li> Hallowed be the name</li> 666 the number of the beast</li> The trooper</li> </ul> entre outras! A abertura com o discurso de Winston Churchill e já entrando com Aces High foi muito legal! Há tempos que ouço essa musica e pensava: "Puxa...Isso ao vivo deve ser muito bom!" e realmente foi! Uma pena o show ter sido tão mal organizado...Nota 0 para a organização do evento que pecou em muuuuitas coisas: Organização na entrada</li> Somente uma saída com um portão de 3 metros mais ou menos para a saída de 60 mil pessoas</li> Atraso de uma hora no show ( por causa da chuva, que não tem nada a ver comigo )</li> Sem proteção contra a chuva que danificou alguns equipamentos</li> Tinham onibus, mas eles nunca paravam pois já estavam lotados</li> </ul> Teve um outro ponto ruim, que foi o show da filha do Steve Harris, que ninguem estava se importando...O Guitarrista até que toca bem, mas o som da banda é chato, e ninguem foi lá para ouvir ela, portanto foi só apurrinhação...:P A chuva ainda ajudou para alem de nos deixar molhados na fila, ainda deixou o autódromo de interlagos transformado num grande pântano de lama. Mas é claro que todos esses contratempos foram aproveitados por alguns, que aproveitaram a lama para fazer um escorregador improvisado no morro para se jogar (hahaha) o que foi muito engraçado! Muitas pessoas resolveram pular as divisórias e subir o barranco para usar como arquibancada. o que foi bem bizarro de se ver tambem. Até que desistiram de pular e destruiram as divisórias para passar para o barranco, juntando centenas de pessoas no barranco, inclusive um doido que estava em cima de uma árvore (!!!) assistindo o show. Muitos comentários do tipo: "Woodstock?" estavam rolando...Lama, bom som, destruição...hahahaha Outra coisa que senti falta foi a pancadaria sadia e divertida que sempre tem...Mas acho que tinha idades bem divergentes por lá, desde crianças até pessoas de cabelo branco, portanto foi mais calmo ( droga... ). Na volta para casa acabei sendo assaltado, mas o drogado apenas levou 20 reias e meu bilhete único (sem créditos), que não foi uma perda muito grande, mas meus primos que estavam comigo perderam os celulares...:( Nunca se sabe quando esses nóias estarão armados... E decidi não reagir... Bem... Relevando tudo isso... O show foi bem legal, e gostei de poder ver o Iron aqui no Brasil! :D Curso de verão da USP Unknown — Fri, 20 Feb 2009 00:00:00 +0000 </a> Com o fim do curso de verão de 2009 da USP, resolvi postar minhas impressões sobre o mesmo! O curso realmente foi muito bom e me ensinou muita coisa! Eu já tinha feito o curso no ano retrasado, mas não cheguei a terminar, por que o professor da época</a> era muito foda e assumia que todos os alunos já sabiam do que ele estava falando, e para mim não significava tanto assim, portanto chegou um momento que eu simplesmente já não estava entendendo mais nada, e o professor já estava jogando matéria loucamente, portanto abandonei. </a> Esse ano, assim como no ano retrasado, não fui sozinho. o Rodrigo foi comigo também, apenas de ele não cursar algo relacionado a programação (cursa redes), ele resolveu fazer o curso. Lá também encontrei a Suelen, que participou do curso no ano retrasado também! Tudo isso sem contar que ainda reencontrei outras pessoas que fizeram o curso junto comigo em 2006, e que resolveram aparecer agora. :D Esse ano tivemos um professor muito gente fina chamado Wanderley Guimarães</a> que explicou a matéria muito bem durante todo o curso, ensinando até coisas que não faziam parte do curso para quem não entendia o suficiente, e indo além do que o curso previa para quem sabia muito mais do que o normal. O professor é realmente muito legal, e a aula realmente se tornava bem divertida de ser assistida, pois sempre tínhamos certeza que viria um conteúdo interessante além dele estar sempre disposto a conversar no final da aula. O que foi abordado no curso: Iteração, indução e recursão </li> Prova de invariantes </li> Análise de tempo de execução de algoritmo </li> Vetores </li> Listas encadeadas </li> Pilha e Fila </li> Buscas simples e busca binária </li> Ordenação </li> Insertion Sort </li> Selection Sort </li> Merge Sort </li> Heap Sort </li> Quick Sort </li> Árvore Binária </li> Árvore Binária de Busca </li> </ul> No final do curso ainda tivemos uma introdução a Programação Dinâmica e a algoritmos de enumeração! :) </a> A cada tópico passado tínhamos um estudo utilizando os outros tópicos já aprendidos. Exemplo: Vamos estudar o MergeSort, então provamos as invariantes / indução, fazemos ele tanto recursivo quanto iterativo, vemos a quantidade de tempo e memória que o algoritmo utiliza e outras coisas mais. As aulas se tornaram bastante interativas pois o Wanderley sempre dava bastante liberdade para a classe intagir com o conteúdo, as vezes até propondo algoritmos interessantes "On the fly" na aula. :D O curso é baseado em 2 provas e um EP (exercício programa) para avaliação. Eu não fui muito bem na primeira prova, e espero ter me saído razoável na segunda, e empenhei uma boa parte do meu tempo noturno no EP para ver se no fim das contas eu ainda consigo sair com o certificado. ;) </a> Como é de praxe, no final do curso tínhamos menos da metade da sala com participantes ativos, pois muitos não se adéquam ao curso ou acham muito difícil e desistem. Nesse momento do curso o Rodrigo já não estava indo mais (o que eu já tinha previsto, não sei por que, e aí está a foto com minha moto sozinha em frente ao prédio do IME), e eu permaneci aprendendo tudo o que eu podia antes do fim do curso, mesmo que minhas notas não estivessem como eu gostaria. :P O EP desse ano foi bem interessante, deveríamos receber uma quantidade indeterminada de palavras, sendo que elas seriam informadas uma por linha pela entrada padrão, e o programa deveria imprimir todas as palavras que eram anagramas umas das outras na mesma linha, e as que não eram anagramas na linha seguinte... Algo como: teste marrocos futebol pothix bolfute eetts socorram</code></pre> Ia retornar: teste eetts marrocos socorram pothix futebol bolfute</code></pre> A princípio parece fácil, mas quando você começa a fazer percebe que não é tão simples assim. ;) Só uma dica...Dá para fazer com lista encadeada. ^^ Espero sair com o certificado desse curso, pois me empenhei o máximo que pude, mesmo com todos os transtornos que aconteceram, e com a terrível falta de tempo. Mesmo querendo sair com o certificado, ele não é o mais importante do curso, o que mais importa é a quantidade de conhecimentos que eu consegui agregar, a quantidade de pessoas interessantes que eu conheci, e a quantidade de experiência que isso me trouxe. :D Pretendo fazer vários posts sobre os conceitos que eu aprendi no curso por que eu acho que será bem interessante passar esse conhecimento para outras pessoas. Eu tenho uma recomendação...Aproveite suas férias de janeiro do ano que vem e vá fazer um curso de verão! ;) DC++ no Linux Unknown — Mon, 09 Feb 2009 00:00:00 +0000 Hoje finalmente estou conseguindo escrever um post sobre o DC++! Desde a Campus Party</a> eu quero escrever esse post mas nunca consigo tempo! Para quem não conhece, o DC++</a> é um software para compartilhamento de arquivos, muito interessante, onde você pode facilmente compartilhar arquivos pela rede local, e por isso mesmo que foi muito utilizado na Campus Party, onde os campuseiros compartilharam terabytes e mais terabytes de arquivos! Atualmente estou utilizando Ubuntu no meu notebook (não tenho mais PC nem em casa e nem no trampo, portanto o meu Slackware se foi...:() e vou mostrar aqui como instalar o seu DC++ nele! Primeiramente vamos instalar as dependencias: sudo apt-get install bzr scons build-essential libgtk2.0-dev libglade2-dev zlib1g-dev libbz2-dev libssl-dev</code></pre> Como é possível notar acima, estamos instalando tambem o Bazaar</a>, que é o software de controle de versão que o DC++ utiliza, infelizmente ainda não tem os binarios para nenhuma distribuição por que ele ainda está em alpha, por isso temos que fazer o download direto pelo Bazaar! bzr branch lp:linuxdcpp</code></pre> Agora temos um branch local do DC++ no nosso computador, portanto é só entrar na pasta e instalar: cd linuxdcpp scons release=1 PREFIX=/usr/local sudo scons install</code></pre> Veja que criei um "PREFIX" para instalar em /usr/local. =) Agora seu DC++ já está instalado e você pode executar ele usando o comando: linuxdcpp</code></pre> E pronto! Agora é só clicar no botão connect e conectar ao endereço de compartilhamento e já era! :) No site que tirei essas dicas</a> eles falam que é bom desabilitar o "Assistive Technology Support" por que deixa o DC++ muito lento. É só ir em: Sistema > Preferencias > ATS Espero que seja útil para vocês assim como foi para mim no Campus Party! Dia difícil Unknown — Sun, 08 Feb 2009 00:00:00 +0000 Hoje o dia foi $#&&! </a> Atualmente moro em Diadema (que não é uma cidade ruim como muitos ouvem falar), e tenho o azer de morar próximo a um córrego, que a prefeitura promete canalizar há mais de 10 anos, e agora parece que finalmente o projeto começou a andar, mas enquanto o projeto não é concluído de vez a coisa ficou pior que o normal... No momento ruim eu tirei algumas fotos</a> (o que sempre faço nesses casos) para mostrar a situação da coisa... Pois é... Já tivemos coisas bem piores que essa no passado, mas a situação é muito ruim independente do quão grande for a desgraça. Hoje para tudo calhou para dar errado e deixar minha cabeça doendo... Foi como um "efeito coringa", que diz que você pode ficar doido igual o coringa se tudo de ruim acontecer com você de uma hora para a outra. Estava eu estudando algoritmo para fazer o meu EP (exercício programa ) do curso de verão, quando o tempo começa a fechar ( ou seja...Muitos relâmpagos e computador desligado, pois já tive muita coisa queimada por causa de raio ) o que já me deixa em alerta para muita coisa, e meus pais tinham saído. Pois bem...A chuva forte começa, e junto com ela os relampagos que eu tinha previsto, e quando eu vi como a chuva estava caindo já me toquei que ia dar problema! Quando vou ligar para o meu pai ex-Sysadmin do meu ex-trampo me liga dizendo que o nosso ex-chefe ligou dizendo que o site está fora do ar, e ele está na estrada nesse momento e não tem como ver. Situação ótima.... Preparar comportas para segurar a enchente, um carro na garagem que precisa ser retirado, relampagos ameaçando o meu computador a cada momento, 3 servidores virtualizados fora do ar... Hora de correr. Aos poucos fui contendo a situação... Meu pai chegou e tirou o carro enquanto eu fui arrumando a comporta, depois corri para ver os servidores (com a ajuda do SysAdmin por telefone), e enquanto iniciava alguns serviços eu corria lá embaixo para ver como estava a situação para tentar ajudar em alguma coisa. No fim das contas temos: Uma rua lotada de lama, que a prefeitura simplesmente ignora</li> 3 servidores no ar novamente e o site funcionando (graças ao SysAdmin, claro!)</li> Felizmente tudo em ordem e nada queimou (como da ultima vez que perdi uma placa mãe, telefone, modem e outras coisas)</li> Um cara totalmente stressado e mal humorado (eu)</li> </ul> Essa confusão toda (principalmente a enchente) me deixa muito mal humorado, e o pior de tudo é saber que não posso fazer nada a respeito. O que tentei fazer foi mandar um e-mail</a> para a prefeitura de Diadema perguntando se eles ao menos podem "fazer o favor" de mandar algo/alguem para limpar a rua após as enchentes até que o projeto que supostamente resolverá os nossos problemas com as enchentes esteja terminado. Agora o que posso fazer é aguardar uma resposta deles ( se é que vão responder ) e seguir rumo... Ruby e Rails no mundo real Unknown — Fri, 06 Feb 2009 00:00:00 +0000 Pessoal, hoje o meu post é para comentar sobre o evento do Guru-sp</a> (Grupo de usuário Ruby de São Paulo), cujo fui um dos fundadores e participo até hoje (quem vê pensa que faz bastante tempo... Apenas uns 4 meses haha). O evento já tem site oficial</a> e está com as inscrições abertas! Pelo que estamos fazendo o evento tende a ser grande, com auditório para cerca de 200 pessoas, com direito a crachá, apostila, Coffee break e etc. Vou passar mais informações sobre o evento: Data: 04/04/2008 ( Sábado ) Horário: das 09h às 18h Local: Century Flat Paulista</a> Palestras / palestrantes que você verá por lá: Carlos Brando - Vai falar sobre testes, que é algo muito importante em projetos! Carlos é o criador da gem Remarkable</a> para integração de Shoulda e RSpec.</li> Vinicius Baggio - Vai falar do seu projeto de Instant Messenger em Rails, e como foi a criação do mesmo, que parece ser bem interessante!</li> Hugo Borges (agaelebe) - Vai apresentar uma palestra sobre Ruby, Rails e empreendedorismo</li> Marcelo Castellani - Vai palestrar sobre Ruby Desktop, falando sobre Shoes, FXRuby e outros</li> Rodrigo Franco (caffo) - Vai falar sobre Outsourcing, e como é o trabalho para empresas do exterior.</li> Maurício Leal - Fará uma apresentação sobre escalabilidade utilizando GlassFish com Rails</li> Fabio Kung - Vai falar sobre análise de código com ParseTree</li> Willian Molinari (PotHix) - Sim... Esse rapaz é nada mais nada menos que....EU! :)</li> </ul> Pretendo falar um pouco sobre o Rubylearning, qual é a vantagem de estudar junto a uma comunidade, comentar sobre as particularidades do curso core do Rubylearning, comentar sobre os novos cursos que estão aparecendo por lá, tirar algumas dúvidas do pessoal que ainda não conhece. Espero ver o pessoal por lá prestigiando o evento. ;) Qualquer dúvida pode postar nos comentários, e vou atualizando o post com as novidades do evento. Update 13/02: Alterado o local do evento! ; ) VIVO online agora funciona no Firefox / Safari Unknown — Fri, 30 Jan 2009 00:00:00 +0000 Boas novas! Eu tinha feito um post</a> sobre os usuários dos serviços da VIVO que tiveram que desenvolver uma extensão para conseguir acessar os serviços do Vivo on line, e agora a vivo anunciou oficialmente em seu blog</a> que o Vivo on line funcionará bem em outros navegadores diferentes de Internet Explorer! :) Tudo bem que isso é um direito nosso e já deveria funcionar em todos desde o começo do serviço, pois prejudicava os usuários de outros sistemas operacionais diferentes do Windows, mas temos que parabenizar a VIVO por trabalhar em cima do problema que tinham e resolver assim como prometeram em novembro do ano passado</a>! Que a VIVO seja a primeira de muitas empresas a refatorar o seu site e sirva de exemplo para muitas empresas que estão aí na internet prestando maus serviços. Campus Party 2009 Unknown — Mon, 26 Jan 2009 00:00:00 +0000 Como sabem eu estive na Campus Party nessa ultima semana, e consegui aproveitar bastante do evento, apesar do monte de coisas que estão acontecendo na minha vida e a correria toda de trabalho, curso e outras coisas. Segue um pequeno resumo do que pude ver por lá: Segunda-feira dia 19/01/2009</h3> Cheguei no evento mais ou menos as 15:00 e consegui entrar rapidinho... Já armei a minha barraca (vide fotos</a>) e deixei algumas coisas por lá para não ficar carregando, e fui conectar na internet que ainda estava bem precária que só funcionava em algumas mesas. Fiquei pouco tempo acessando a internet, pois tive que fazer a minha peregrinação diária de ir para a USP para fazer o curso de verão de tópicos de programação. Voltando do curso (mais ou menos 23:00), após passar em casa volto para cá para ver como estão as coisas, e ainda consegui ver a abertura do evento, com direito a Serra, Kassab e o Tim Berners Lee</a>! Após todas as festividades fiquei esperando as primeiras atividades que supostamente começariam 1:00, mas não vi nada de diferente e continuei na minha mesa até umas 2:30 mais ou menos quando resolvi me recolher para a minha barraca e dormir. </a> Veja aqui as fotos do dia</a> Terça-feira dia 20/01/2009</h3> Acordei as 8 da manhã para ver a palestra do Fabio Akita sobre ecossistema RubyOnRails e até fui mencionado por ele quando ele falou sobre o Rubylearning</a> (obrigado Akita!). Foi uma palestra bem legal falando dos mitos do Rails, mostrando um pouco de código e tudo mais...para quem não conhece o Rails foi uma geral bem legal. Depois da palestra fui conversar com o Fabio e ficamos um bom tempo batendo papo enquanto conhecia a equipe da Locaweb ( inclusive o @locaweb_reply</a> ! haha ). O pessoal da Locaweb estava com uma camiseta bem legal com os dizeres: 1F U C4N R34D 7H15 U N33D 70 G37 4 L41D </blockquote> Tentei de toda forma ganhar uma, até por que era a camiseta de Linux da Locaweb, mas no fim das contas não consegui e fiquei somente com uma revista mesmo. Consegui começar a aproveitar a internet, fazer uns downloads e ver uns vídeos! :) Depois comecei a procurar (ou não) e encontrar uma galera legal, como o agaelebe</a> e o Mario Rinaldi</a> da fundação Mozilla no Brasil. Sai na hora do almoço e fui para casa (sim, estou almoçando e tomando banho em casa, já que moro perto daqui, então estou apenas dormindo aqui por diversão), quando voltei ja era 16:00, e ainda consegui assistir a apresentação sobre Podcasts com Maestro Billy</a>, Mellancia</a>, Jovem Nerd, Azaghal</a>, Dani Brau e Guilherme Felliti</a>, que por sinal foi bem interessante! No final ainda consegui tirar uma foto com o Alottoni</a> e uma com o Azaghal</a> ( e nessas fotos estou comprovando que não sei sorrir. :)) Ahhh! Outra coisa legal que consegui foi além de conhecer o Karlisson, ainda consegui tirar uma foto</a> com a celebridade criadora do nerdson.</a> Encontrei tambem meio que de passagem a Bruna Griebeler</a> quando eu estava chegando e ela saindo...Deu para conversar bastante ainda com o pouco tempo que tinha. :) Chegando aqui tarde novamente, percebi que perdi a palestra sobre desenvolvimento de games com C++, que é uma das coisas que estou estudando... Tive 2 notícias, uma boa e outra ruim... A boa era que iam ter palestras de desenvolvimento de games a semana toda! (uhuuu) e a notícia ruim é que cai no horário do curso de verão (duuuhhh), portanto não vou conseguir assistir nenhuma. </a> Veja aqui as fotos do dia</a> Quarta-feira dia 21/01/2009</h3> Peguei um HD externo de 40Gb para fazer download de umas coisas para um colega meu, e descobri o DC++</a> que o pessoal estava usando aqui internamente, o que deixa o compartilhamento de arquivos com uma velocidade monstruosa, e comecei a encher o meu HD que estava com 160GBs livres ( fora o HD externo de 40 ). Assisti uma palestra sobre SEO, que foi bem interessante apensar do som que estava horrível de ouvir por causa dos outros sons que estavam em volta e o volume do som dessa area que estava muito baixo. Assisti a palestra do Luciano Ramalho ( presidente da associação Python Brasil</a>) sobre Python (obviamente), que apesar de alguns problemas com o projetor, foi interessante e mostrou várias coisas diferentes. Após a palestra ainda consegui conversar com o Luciano um pouco (já fiz um curso de Python ministrado por ele na Impacta). Assisti a ótima palestra do Manoel Lemos do Blogblogs</a>, que falou sobre a infra-estrutura do blogblogs e do Brasigo ( vide fotos</a>), que foi crescendo aos poucos, assim mostrando um case de sucesso que começou simples e aos poucos foi crescendo com inteligencia. Na minha opinião essa palestra é ótima para desenvolvedores Rails (e não Rails também) que tem aplicações que podem crescer rápidamente e precisar de uma mudança de estrutura para continuar prestando um bom serviço. No final da palestra apareceu um slide dizendo "estamos contratando novos Jedis"! Isso muito me interessa! ;) Assisti no CPLabs uma apresentação sobre o OpenVC, que é uma biblioteca C++ para trabalhar com webcam, que é muito interessante! Dá para captar movimentos e fazer várias coisas divertidas! Na palestra foram apresentados vários vídeos legais. O mais legal do dia foi ter cumprimentado e tirado uma foto com nada mais nada menos que John "Maddog" Hall</a>!! Sim, ele mesmo, o do software livre e diretor executivo da Linux International! Finalmente hoje encontrei a Bruna Griebeler</a> novamente, mas como sempre na saída de um dos dois, mas dessa vez er a minha (estava saindo para almoçar em casa), mas após ficar batendo papo, aproveitamos para fazer inscrição para ganhar um domínio grátis</a> por um ano no stand do IG! E acabei indo almoçar as 16....hahaha Após voltar do curso da USP, tive que começar a me focar nos exercícios para entregar na quinta feira (sim...é amanhã), portanto fiquei até as 3 da manhã trabalhando nisso, e só não fiquei mais por que estava muuuuiiitooo frio, portanto preferi ir para a minha barraca quentinha. :P </a> Veja aqui as fotos do dia </a> Quinta-feira dia 22/01/2009</h3> Acordei um pouco mais tarde e tirei o dia para mexer nos exercícios, portanto fiquei pouco na Campus Party. Hoje, além do Mario Rinaldi que resolveu aparecer novamente (ele tem o poder de desaparecer... hahha ), o Marcelo Castellani</a> do guru-sp</a> apareceu por aqui também, o que rendeu a única foto do dia com uma qualidade horrível</a>. Conversando com o Rinaldi eu consegui pegar a minha camiseta do Mozilla Firefox</a> ( melhor navegador do mundo! haaha ), e de quebra conheci outro cara da fundação Mozilla, que é o Bruno Magrini! :) Depois disso tive que resolver uns problemas e terminar uns exercícios em casa para ir para USP. Depois de resolver mais problemas volto ao campus party para escrever no blog até as 5 da manhã, estudar C para a USP (por que tenho prova na segunda feira) e baixar trecos legais! :) </a> Veja aqui as fotos do dia </a> Sexta-feira dia 23/01/2009</h3> Sexta feira foi um dia legal por aqui! já menos preocupado com a lista de exercícios (mas preocupado com a prova de segunda), eu consegui fazer bastante coisa, conversar com várias pessoas, e tudo mais. Encontrei o pessoal do Guanabara.info</a>! Conversamos com o Gustavo Guanabara, demos uma volta pela feira, vimos como são feitas as pautas do Podcast</a>, conhecemos o Kaue Linden da HostNet</a> (que por sinal é muito gente boa!), ganhei uma camiseita do Guanabara.info e uns adesivos! Foi bem divertido encontrar essa galera e conhecer o Guanabara pessoalmente. :) No fim das contas ainda fiquei pouco tempo por aqui (das 19:00 as 22:00), mas valeu a pena! </a> Veja aqui as fotos do dia </a> Sábado dia 24/01/2009</h3> Após ficar até as 4 da manhã estudando na casa de um amigo, durmi um pouco e vim direto para cá! :) Encontrei o Marcelo Castellani do guru-sp</a>, e ficamos um bom tempo batendo papo com o Fabio Akita</a>, e isso se tornou o segundo encontro do guru-sp ( que estava marcado aqui na Campus Party)! :) Após as conversas eu peguei minha camiseta do Guru-sp com o Marcelo e fiquei com as camisetas do pessoal que talvez iria aparecer por aqui, e consegui entregar uma para o Ricardo Yasuda ( Shadow11)</a>. Assisti um pedaço da palestra do Karlisson sobre quadrinhos, onde ele mostrou algumas particularidades das imagens, e fez uma tirinha durante a palestra ( infelizmente cheguei tarde para ver essa parte ). Assisti um pedaço da palestra sobre app engine do pessoal do GruPy</a>, que foi bem interessante! Eles trouxeram palestrantes internacionais para falar sobre app engine, e o assunto foi bem legal para quem não conhece o app, está afim de brincar com Python e quer uma boa estrutura para deixar sua aplicação gratuitamente! :) E teve várias outras palestras legais que eu gostaria de assistir, mas infelizmente eu só posso estar em um lugar ao mesmo tempo ( acho que eu preciso da filosofia "Fork you" do GitHub...haha ), portanto não pude assistir outras como a de Desenvolvimento de games com C++... Tinha planejado ir para casa e depois ir para a casa de um amigo estudar a madrugada toda novamente, mas no fim das contas acabei ficando na Campus Party mesmo por vários motivos, e foi bem divertido ficar lá papeando e se divertindo com o Pessoal da Moz-br</a> (Clauber-halic, Bruna Griebeler</a>, Hermano Silva e Mario Rinaldi</a>, o Karlisson</a> e o InFog</a> (vejam nas fotos</a>). Teve uma coisa que precisa ser comentada! Teve dois caras correndo pela Campus Party nesse dia, um vestido de PacMan e o outro vestido de fantasma com uma sirene! hahahaha! Parabens ao cara que pensou nisso, por que foi muito criativo, pena que não tenho as fotos. Desmontei minha barraca e saí de lá as 6 da manhã mais ou menos. ;) </a> Veja aqui as fotos do dia </a> Considerações finais</h3> A Campus Party para mim terminou no Sábado, mas domingo a area Expo ainda estava aberta para visitas, mas resolvi não aparecer por lá já que na area Expo não tinha muita coisa. Gostei bastante do evento! Considerei como uma aventura, passar uma semana dormindo fora ( durmindo pouquíssimo e sem horário certo hehe ), acessando a internet rapidíssima, comendo pouco, estudando, fazendo networking e se divertindo! Conheci muitas pessoas legais (e outras que pensei que fossem legais e nem são), me diverti bastante, tirei fotos legais, preparei caminho para o futuro ( se acontecer algo eu postarei ), baixei muita coisa ( 200GB), gastei uma graninha com estacionamento e refeição e estou bem mais tranquilo para voltar ao trabalho depois de uma semana fazendo coisas que eu adoro (programar, conversar sobre tecnologia, acessar a internet). Tiveram coisas bem legais acontecendo por lá e outras que não foram tão legais, mas é claro que todos os eventos tem seus defeitos, e esse evento para mim foi muito bom! No fim das contas...pretendo voltar lá ano que vem! :D Usuários resolvem os problemas da VIVO Unknown — Tue, 13 Jan 2009 00:00:00 +0000 Primeiramente quero parabenizar o Diogo Santos</a> pelo seu add-on para Firefox</a>, que faz com que o botão "entrar" do site da Vivo funcione sem que você tenha que usar javascript para manipular pela barra de endereços. Parabéns Diogo, é uma ótima contribuição para a comunidade. Agora vem a hora da crítica... Como que os usuários tem que ficar desenvolvendo formas alternativas para acessar os serviços que deveriam funcionar para eles, mas por descaso e serviço mal feito não lhe são concedidos? Eu acho impressionante o descaso de tais operadoras por determinadas coisas. O pior de tudo é que quando você entra em contato pelo suporte a resposta que te dão é a seguinte: Não damos suporte a outro navegador que não seja o Internet Explorer </blockquote> Ou seja... Caso você esteja no Linux ou no MacOs o problema é seu... Eles não estão nem aí se estão simplesmente excluindo essas pessoas. A nossa sorte é que a comunidade é auto-suficiente, e temos pessoas que trabalham a favor da comunidade (e não a favor da VIVO), sempre ajudando para que os serviços mal feitos funcionem, e o Diogo é um ótimo exemplo disso. Após acessar o site da Vivo com o plugin do Diogo, eu percebi que ainda tem vários serviços que ficam indisponíveis, mas quem sabe a comunidade dá um jeito nisso com o tempo, ou até mesmo a VIVO toma vergonha na cara e resolve prestar um serviço de internet de qualidade. Fica aí a minha crítica a VIVO</a> e a parabenização ao Diogo</a>! Fora IE6 Unknown — Mon, 12 Jan 2009 00:00:00 +0000 Já está mais do que na hora de eu fazer um post sobre isso, e acho que não há momento mais propício do que esse afinal, até o Google já está dando alertassobre isso no Gmail</a>. Sabemos que o Gmail é não é o serviço mais acessado do Google, mas isso já é uma grande ajuda para alertar os desavisados que esse navegador já passou da hora de deixar de existir, e quem sabe num futuro talvez distante ( espero que não tão distante assim ) o google resolva fazer algo parecido com o Orkut! :) Há muito na internet sobre o quanto o IE6 é ruim, e minha opinião não difere muito da opinião dita em posts como o do Fabio Akita</a>, ou do Canha</a> por exemplo ( O logo ao lado foi tirado do blog do Fabio Akita</a> todos os créditos para ele! ). Muita gente que me conhece pode dizer: Ahhh....vc não gosta da Microsoft e fica fazendo propaganda de browsers Open Source </blockquote> Mas na verdade não é somente por isso...Mesmo que vc vá continuar com o IE (não recomendado, mas menos mal), pelo menos atualize para uma versão mais recente, pois usar o IE6 hoje em dia é completamente inaceitável! Alguns ainda tem a audácia de me perguntar o por que de eu ser contra o IE6 e aqui vão alguns argumentos completamente lógicos para o fato: É um produto desatualizado que já tem uma versão mais nova lançada e outra no forno para sair sei lá quando</li> É um produto que foi lançado numa época em que ele precisava estar na frente para bater outros navegadores</a>, portanto não estava nem aí para padrões, bom desenvolvimento ou qualquer outra boa prática que pudesse existir.</li> Você que usa IE6 não sabe o mal que está fazendo para tantas pessoas que trabalham com internet e precisam perder preciosas horas do seu dia para ficar fazendo hacks para que seu site ( que segue os padrões de desenvolvimento para internet</a>, bem documentados aqui</a> ) funcione num produto desatualizado que deveria ter sumido já.</li> Ele dá um grande break na evolução das tecnologias, pois muitas das coisas legais que os desenvolvedores querem fazer ( transparencia por exemplo precisa colocar Hack bizarro para funcionar no IE6 ) devem ser pensadas e repensadas, pois pode não funcionar legal no IE6, e seu chefe com certeza não vai deixar você colocar no ar algo que não funcione legal no IE6, por que ainda tem uma grande massa que usa isso.</li> </ol> Já ouvi argumentos de pessoas que gostam do visual do IE6, que é totalmente aceitável, afinal, qualquer pessoa pode usar o que acha mais legal, bonito, fácil.,ou sei lá o que consideram, mas se for somente por isso você pode seguir a dica que o canha deu no post dele</a>: No Firefox, inclusive há um tema que se parece com o IE6</a> para você não se sentir perdido. E o melhor: todos estes navegadores possuem versão em português. </blockquote> Eu estou fazendo a minha parte para começar o ano bem e estou instalando aqui no meu blog um plugin para alertar os usuários desse software antigo para atualizar para algo melhor. Não sabe como fazer? Veja aqui os links para instalar um browser diferente: Firefox</a></li> Chrome</a></li> Opera</a></li> Safari</a></li> Internet Explorer 7</a> (prefira os acima, mas se gostar mesmo do IE instala esse que é melhor)</li> </ul> Acho que consegui dar motivos o suficiente para você trocar de browser, se ainda tem alguma coisa que você usa não terá em outros browsers, me avise que farei o possível para encontrarmos uma boa solução para isso. Deploying a simple Merb application on Locaweb Unknown — Wed, 07 Jan 2009 00:00:00 +0000 I writing this post to help my friends of Rubylearning</a> with a little Merb</a> application deployment on Locaweb</a>. I'm just translating some informations that you can find here</a> in portuguese. Lets get started! :D First open the Domain Manager</a> (gerenciador de domínios) on Locaweb Panel (painel da Locaweb) and configure the pointer of your main site to other directory on public_html of your account (this directory don't need to exist). Follow this steps: Click on "alterar" (change)</li> Change the "Diretório Web" (web directory) to the new diretory</li> And click on button "Salvar" (save)</li> </ol> Transfer your application to this directory on your host. For this example, lets say that your application is called "sample_merb", so, connect via SSH on your account and create the directory "rack_app": mkdir -p rack_app/sample_merb</code></pre> And move your application to there. Your application must to have a file called "config.ru" to be executed by Phusion Passenger, so, you need to create this file on your application folder (rack_app/sample_merb on this case) with this content: require 'rubygems' require 'merb-core' Merb::Config.setup(:merb_root => “.”, :environment =>; ENV['RACK_ENV']) Merb.environment = Merb::Config[:environment] Merb.root = Merb::Config[:merb_root] Merb::BootLoader.run run Merb::Rack::Application.new</code></pre> Now you need to create a symbolic link on your public_html diretory, as you have configured on your Domain Manager (gerenciador de domínios) of Locaweb Panel. ln -s ~/rack_app/sample_merb/public ~/public_html/sample_merb</code></pre> By using this simple configuration you will have your application pointed by apache with Phusion Passenger. Just to you know, you can see the merb gems that are installed with: gem list | grep merb</code></pre> Hope this help you on how to make your simple application works on Locaweb. ;) New year is coming Unknown — Wed, 31 Dec 2008 00:00:00 +0000 Estou apenas postando para dizer que nesse novo ano eu pretendo postar mais sobre programação! Essa é a primeira virada de ano desse blog, então resolvi postar meus "planos" para o próximo ano. Como o blog é novo eu comecei a escrever faz pouco tempo e estou pegando experiência aos poucos, e talvez agora nesse novo ano a qualidade dos posts aumente! (ou não...heheh). Não sei bem qual rumo minha vida vai seguir nesse novo ano, o que eu vou ter que aprender e estudar, talvez eu tenha que aprender coisas que eu não tinha planejado e isso pode tomar uma boa parte do meu tempo, mas eu pretendo postar todos os meus estudos aqui, portanto terei algum material interessante aqui. Esse ano estarei em alguns eventos por aqui (como todo ano), e eu pretendo postar sobre eles aqui no blog! Um evento que já está com minha presença confirmada é o Campus Party Brasil</a>, que parece que vai ser bem lega, além da conexão monstruosa que terei lá vou encontrar umas pessoas bem legais. Eu estarei fazendo o curso de verão da USP</a> (tópicos de programação) no mês de janeiro no período noturno, portanto se alguem for fazer tambem me avise que nos encontraremos por lá! ;) Bem...É isso! Um feliz ano novo a todos os leitores do Blog e amigos e nos veremos em 2009! Concurso Quarto mais Nerd Unknown — Sat, 27 Dec 2008 00:00:00 +0000 Bem...Estava eu aproveitando as férias (tanto da faculdade como as férias coletivas do trabalho) para colocar as coisas em ordem, começando pelo meu quarto que é o lugar da casa que eu passo mais tempo e eu gosto de manter bem organizado, portanto já tratei de aproveitar meu tempo livre para deixar ele do jeito que eu queria. Comprei uma pequena estante para colocar mais livros e outras coisas legais, encaixotei várias coisas que eu quase nunca vou usar, e joguei 2 sacolas de papéis e outras coisas inúteis fora. Com isso tudo acabei até achando 2 adesivos legais (um do Quake III e outro do Unreal Tournament GotY) que eu tinha para colar no meu capacete</a> e na minha moto</a>. :) No fim das contas finalmente consegui deixar o meu quarto como eu queria: </a> </a> mais fotos aqui</a></a> Acho que consegue me descrever bastante: Fora da mesa: Violão e guitarra</li> Posters dos 3 filmes d"O Senhor dos Anéis"</li> Mochila preta</li> </ul> Na mesa: Vários porta cds com DVDs de arquivos e outras coisas mais</li> Um porta cd com alguns cds de musica como Metallica, Bach ( da coleção da folha se não me engano ) e outros.</li> Palm e teclado ao lado do monitor</li> Roteador Wireless</li> Pastinha do Google</li> Livro de C++</li> </ul> Na estante: Peças e relógio de xadrez da Jaehrig</li> Tabuleiro de xadrez portátil</li> Mangás Sakura Card Captors (curto esse esquema de cartas)</li> Pasta com muitas cartas de Magic - the Gathering (na parte de baixo da estante)</li> PSP</li> Alguns livros: O senhor dos anéis - Edição completa, Universidade Hacker, Repensando a web com Rails, Servidores Unix....</li> Várias revistas: Linux Magazine, Revista Locaweb, Revista WWW</li> Várias apostilas e livros impressos: Hackerzine, Guia do Linux 7 do Carlos Morimoto</li> Pastas de desenhos ( faz muito tempo que não desenho algo, mas fica a recordação de quando desenhava )</li> caderno e pasta da faculdade</li> Notebook</li> </ul> Em cima da estante: Crachás dos eventos que eu participei (faltando alguns que se perderam)</li> </ul> E aí que vem a parte que eu queria chegar!:D Aqui é o maior concurso de todos os tempos, se você tem um quarto tão nerd como o meu tire umas fotos dele e post aqui para eu ver, e quem sabe você pode ganhar... humm..... adivinhe.... SiiimmM!! Toda a honra e a glória de ter um quarto mais nerd que o meu... E o meu respeito tambem, que não vale tanta coisa assim, mas pelo menos vc vai se divertir! :) Coloquem as fotos no picasa/flickr/ImageShare/QualquerOutroQueVcConheça e poste os links aqui nos comentários. Configurando seu git para começar a usar Unknown — Sun, 21 Dec 2008 00:00:00 +0000 Meu ultimo post foi sobre como subir um projeto para o GitHub</a>, mas me veio agora uma vontade repentina de falar como deixar seu git legalzinho para começar a criar repositórios e contribuir com códigos! Serão apenas configurações básicas, mas que são bem úteis quando você estiver usando o Git ativamente! Antes de mais nada precisamos instalar o Git, portanto é só baixar ele no repositório oficial</a> e fazer a instalação referente ao seu sistema operacional. No meu Slackware já veio o Git instalado belezinha, portanto foi moleza! No máximo eu atualizei com o SlackPkg.</li> No Ubuntu se eu não me engano eu precisei instalar, mas foi moleza, só baixar o .deb oficial e usar o dpkg -i :)</li> </ul> Vamos as configurações: Primeiramente precisamos de configurar o nosso nome e e-mail: git config --global user.name "PotHix" git config --global user.email "PotHix@pothix.com"</code></pre> Algora alguns Alias para facilitar: git config --global alias.st status git config --global alias.co checkout git config --global alias.ci commit git config --global alias.br branch</code></pre> Agora algumas cores para facilitar a leitura quando digitarmos os comandos: git config --global color.status auto git config --global color.branch auto git config --global color.diff auto</code></pre> Podemos já criar um projeto simples e enviar para o GitHub</a> assim como eu fiz no post anterior</a> mas agora já usando os nossos alias para ficar mais fácil! :) Com Git podemos fazer várias outras coisas que vou falando aos poucos em outros posts, esse aqui é só para mostrar como deixar seu git mais legal para começar. Iniciando seu primeiro projeto no GitHub Unknown — Sun, 21 Dec 2008 00:00:00 +0000 Hoje estou aqui para postar um pouco sobre o GitHub! =) Minha idéia hoje é apenas mostrar como você inicia um projeto por lá, ou seja, enviar um pequeno repositório git e deixar no GitHub, e conforme os meus progressos eu postarei mais coisas por aqui! ; ) Antes de começar tudo isso você precisar ter cadastro no GitHub (obviamente) e já ter uma public-key cadastrada. Para cadastrar uma public-key é só logar no GitHub, clicar em account (no canto superior direito) e clicar em "add public key" que vão aparecer os campos para inserir a mesma. Você pode encontrar a sua public key no diretório ~/.ssh</code> com o comando: cat id_rsa.pub</code></pre> Caso ele não exista basta acessar sua home (~) e cria-lo com: ssh-keygen -t rsa</code></pre> OBS: Eu tenho um post</a> com mais informações sobre chave e SSH. Depois pegar o conteúdo do arquio id_rsa.pub e colocar lá no GitHub. Voltando a criação do repositório... Primeiramente crie um diretório por aqui</a>: Depois de criar você já terá um local acessível para enviar seu código, que por sinal ainda não existe, portanto....Vamos criá-lo! :) Primeiramente crie um diretório qualquer: mkdir codes</code></pre> Acesse o diretório: cd codes</code></pre> E vamos iniciar o git nesse repositório: git init</code></pre> Coloque aqui seu arquivo de código (não necessáriamente código, mas nesse caso vamos usar código ;)) e vamos adicioná-lo ao git: git add mycode.rb (obs: Ruby o/)</code></pre> Agora vamos dar um commit do que fizemos usando "-m" para deixar uma mensagem do motivo do commit: git commit -m "Meu primeiro commit"</code></pre> Agora vamos adicionar como origem o nosso projeto criado no GitHub: git remote add origin git@github.com:seu-usuario-no-GitHub/nome-do-repositorio-criado.git</code></pre> E depois é só dar um: git push origin master</code></pre> E lá está o seu código no GitHub! :) Tudo que eu falei aqui está no tutorial do GitHub quando você cria um diretório: http://github.com/guides/setting-up-a-remote-repository-using-github-and-osx</a></a> Por enquanto é isso! Algo bem simples só para você não se assustar quando lhe falarem de GitHub. First post in English here Unknown — Tue, 16 Dec 2008 00:00:00 +0000 Hi international friends! :) I'm just posting to inform that I want to post some content in English too! I'll try to make a RSS Feed only for my English posts, so you don't need to view my portuguese posts on your feed reader. :) As everyone knows, my English is not so good, but I think you can understand me well! Any English errors (I'm sure it will have a lot of them) please tell me and I'll correct it asap. Hope to have you following this blog! :) Voltando a ser um gamer Unknown — Sun, 14 Dec 2008 00:00:00 +0000 Esse aqui vai ser um post um pouco fora do escopo "programação", mas ainda no escopo "nerd"! :) Com esse post eu pretendo introduzir uma nova série (não achei palavra melhor) posts sobre os games que eu estou jogando atualmente, postanto umas opiniões e tudo mais, e quem sabe até alguns jogos que eu pretendo instalar no Linux. Vou contar um pouco do título "Voltando a ser um gamer". Eu sempre gostei de jogar vídeo games desde pequeno, a ponto da minha mãe dizer que eu só podia jogar 3 horas por dia... hahaha... Tive poucos vídeo games pois meus pais não tinham tanto dinheiro assim para ficar comprando novos, portanto se eu quisesse algo novo eu tinha que me virar e comprar. Primeiramente tive o bom e velho Atari</a> (era bem pequeno nessa época) Mais pra frente ganhei um SuperNES</a>, que me trouxe bons divertimentos com vários jogos clássicos como TopGear, Super Mario World, Road Rash, Samurai Spirit, International Super Star Soccer (eu ainda gostava de futebol nessa época), Street Fighter, Final Fight, Double Dragon e muitos outros! Saí do SuperNes para ir para o Playstation (tive que me virar e rifar o meu SuperNes para comprar o PS), onde me diverti bastante com Ace Combat 2, Fighting force, Syphon Filter, Monster Rancher 2, Spider Man, Street Fighter Ex Plus, Metal Gear Solid, Soul Edge, Bload Roar e mais vários jogos legais. Vendi meu Playstation, e aproveitei para comprar um GameBoy Color</a> (sim...Foi na época do Pokémon) Um adendo na minha vida de Gamer! Eu sempre participava dos encontros do canal3</a> com meu primo Marcelo Nietto</a> e era sempre muito legal</a> ver vídeo games antigos (e de vez em quando até uns OFF-TOPICs com vídeo games novos!), jogar o bom, velho e divertido campeonato de War Lords! Felizmente nessa época eu comecei a trabalhar, não oficialmente mas já conseguia um dinheirinho, portanto comprei um dreamcast</a>, mesmo sabendo que a linhagem de jogos dele estava acabando e a SEGA estava desistindo de continuar a investir, mas achei que valia a pena, afinal, além dos meus amigos tinham, e eu tinha visto jogos bem legais, como SNK x CAPCOM, Marvel x CAPCOM 2, Crazy Taxy e etc. Me diverti muito com o Dreamcast tambem! Joguei bastante Shenmue (o melhor jogo de todos os tempos, que eu quero saber o resto da história até hoje), Record Of Lodoss War, Tony Hawks 2, Le Mans 24 Hours, Sega GT, Sonic Adventure 2 (era tanto vício nesse que quando saia levava o VMU com o Sonic para jogar heheeh), Soul Calibur, Sega Tennis, e vários outros bem legais! Agora depois disso tudo começa a "decadência" da vida de gamer...:P Vendi meu GameBoy por que já nem estava jogando mais... Finalmente comprei meu primeiro computador (com 16 anos de idade... Só quando comecei a trabalhar de verdade ), com o seguinte pensamento: "Vou conseguir rodar uns jogos da hora!", com uma GeForce4! (agora não é muita coisa, mas na época era foda!). Joguei bastante coisa legal, como Need For Speed Underground, Need For Speed Hot Pursuit 2, Diablo, Diablo 2, Halo, Gunbound, Metin 2, Unreal Tournament esse eu me matei de jogar! A ponto de ir na casa do meu primo com vários disquetes e voltar com os novos Skins que ele baixava! :D ) e mais vários outros! Bem, mas voltando a decadência ( de gamer, obviamente )...Nesse tempo eu comecei a conhecer mais o Linux e a programação! E meu espírito gamer se foi de vez! :P Encostei de vez o meu Dreamcast, mas não tive coragem de vender</li> Abandonei os jogos de computador, não que eu nao gostasse mais, mas eu tinha mais vontade de programar ou estudar coisas do gênero enquanto eu estava em frente ao computador, e tambem com o meu curso na ETE, sempre tinha alguma coisa para fazer.</li> Nesse tempo eu tambem comecei a trabalhar com programação, o que me animou mais a estudar para fazer outras coisas! :)</li> </ul> Pois bem... Tinha me livrado dos games e estava feliz como programador e jogador casual quando dava. Ficou assim até poucos meses atrás, quando eu fui para a faculdade e me aparece um colega meu com um aparelho portátil preto com logotipo da Sony que eu já tinha ouvido falar...PSP! Isso mesmo! E ele me contou como se divertia com o bichinho, que dava para ver vídeos, ouvir musica, e jogar vários jogos bem legais e tal. Tudo isso somado com meu novo colega de faculdade chamado Leonardo Foroni, que tem as mesmas características que eu tinha na minha época de gamer hardcore. Adivinha no que deu? Sim! menos de 1 mês depois estou eu com o meu PSP! Demorei um pouco para começar a jogar no bichinho, mas aos poucos eu estou vontando a me tornar um gamer hardcore! Inclusive criei junto com os meus primos ( os velhos amigos de games ) o NerdNightGames</a>, que é um evento interno na casa do meu primo</a> onde passamos uma madrugada (geralmente de sábado para domingo) só jogando em rede, tanto de PSPs como de computadores! Então hoje mantenho Dreamcast guardadinho e meu PSP sempre com jogos legais, onde jogo sempre depois do almoço, e a noite antes de durmir! Como o PSP está sempre comigo (ouço meus Podcasts nele tambem) sempre que possível e seguro eu estou jogando! Os jogos de PC estão instalados no windows Vista que veio no meu notebook (deixei numa partição minúscula), que por sinal eu só uso no Nerd Night Games, afinal, para que mais o Windows serve senão para usar como vídeo game. ;) Confesso que agora que sou programador o velho sonho de criança de se desenvolver jogos (que eu destruí pensando que era um sonho impossível de criança, assim como aqueles que queriam ser jogadores de futebol) veio a tona, e eu ainda vou desenvolver algo, mesmo que seja pequeno. Com isso eu tambem me tornei uma pessoa mais crítica quanto a jogos, prestando mais atenção na inteligencia artificial dos inimigos, pequenos erros que acontecem e passam meio desapercebidos e outras coisinhas, o que me motiva mais ainda a escrever sobre os jogos que estou terminando! Só para finalizar, outra coisa que está me motivando a voltar a jogar agora é o Podcast NowLoading</a> que tem sempre informações muito legais e conteúdo bem divertido! Como eu disse... Esse post é para vocês entenderem por que eu vou começar a postar um pouco alguns jogos tambem. :) No mais nada mais! :) GameReview: Need For Speed - Most Wanted Unknown — Sun, 14 Dec 2008 00:00:00 +0000 Como eu disse no ultimo post</a> agora eu vou fazer uns pomsts sobre uns jogos que eu estou voltando a jogar no PSP, dizendo o que eu achei, como foi jogar ele, defeitos, qualidades, gosto pessoal e tudo mais! Primeiramente vou falar sobre o gosto pessoal. Eu nunca fui muito fã de jogos de corrida, foram poucos que realmente me fizeram jogar até o final, e esse realmente foi um deles! Outros que eu realmente recomendo são: Speed Devils (dreamcastd), Crash Team Racing ( playstation), Le Mans 24 Hours (dreamcast) e Demolition Racer ( dreamcast). Bem, agora começando a falar sobre o que diz o o título desse post: Need For Speed - Most Wanted</a>! Esse jogo segue a mesma linha dos velhos Need for Speed Hot Pursuit</a>, mas agora misturando com a linha Need For Speed Underground</a>! A história</h3> Se baseia em você ser o Mais procurado (qualquer um que saiba um pouco de inglês já teria pensado em algo parecido né? :P) entre uma lista de Tuners (sei lá como traduzir isso... Modificadores de carros), sendo que você inicia na 15 posição da lista e vai passando por várias corridas até chegar ao dono da posição que você quer conquistar, e vencendo ele você passa ele para trás e toma sua posição, assim podendo disputar a posição acima. A evolução no jogo</h3> Se baseia em respect (respeito), portanto quanto mais respeito você tem mais você pode avançar, então não necessariamente você precisa ganhar do cara que está na sua posição atual para poder disputar corridas da outra posição, desde que você consiga respeito o suficiente para passar para o próximo nível sem vencê-lo. Você consegue respeito tanto nas corridas como em propostas que lhe são feitas após terminar uma corrida. As propostas são desafios do tipo: Despista os policiais e recebe mais respeito ou fica sem nada</li> </ul> E se você aceitar, você deve se distanciar dos policiais o suficiente para despista-los antes que eles se distanciem de você e lhe façam barreiras para furar seus pneus ou consigam te bloquear e prender. Multiplayer</h3> Não cheguei jogar em modo multiplayer por falta de oportunidade, pois não tenho amigos jogando PSP sempre por perto, e meus primos do NerdNightGames ainda não estão jogando esse jogo. O modo infrastructure só funciona com internet que está configurada como WEP (não sei por que...), portanto como a minha está configuradinha como WPA eu não consigo usar...No trabalho é a mesma coisa, portanto o modo infrastructure não mudou nada para mim. :( O modo carrer</h3> É bem interessante, apesar de não me empolgar com esse tipo de modo, eu achei legal ter que conseguir carros novos para modificar, e sempre esperando que seja liberada uma nova atualização de performance para que eu possa vencer determinada corrida e tal. Tem uma hora que o jogo realmente te força bastante por que seu carro não é bom o suficiente para vencer e você não pode errar nenhuma vez para conseguir ganhar, alem de ser uma pista cheia de curvas e tráfego, ou seja, é o ápice do jogo! Depois disso você consegue carros mais legais e dá para terminar o jogo tranquilo. Após você passar um adversário e ganhar seu nível você ganha tambem um evento bônus para conseguir upgrades visuais bônus tambem! :) A polícia</h3> É muito chata e te atrapalha bastante nas corridas, não que isso seja um erro, afinal o trabalho da polícia lá é esse mesmo, e uma coisa que eu achei legal é ela tambem atrapalhar os adversários! Já aconteceu da polícia estar tão "Sangue nos olhos" que todos os meus adversários estavam presos e eu tinha 3 viaturas me cercando até o final da corrida! Fora as várias vezes que eu tenho uma grande vantagem e a polícia me alcança ( não importa se você tem uma lamborghini gallardo que anda a 210 mph, ela vai te pegar ) e vira meu carro para a direção contrária. Momentos WTF</h3> Algumas das inteligencias artificiais estava meio bizarras... Aconteceu de eu ganhar a corrida por que ao chegar perto da linha de chegada o meu adversário deu uma leve freiada não se sabe por que... não tinha adversário nem policia na frente dele. (???) A fisica de batida dos carros tambem é meio bizarra... Quando você vem a toda velocidade numa rua e bate de frente com o carro muitas das vezes você continuava andando e o carro que você bateu saia voando em parafuso e ficava uns 10 segundos capotando (???) Eu cheguei a ver um carro coadjuvante desaparecer do nada após eu fazer uma curva :P Soundtrack</h3> Dou muito valor a soudtrack dos jogos, e desse jogo até que ficou legal! Como sempre bem baseada em black ( não curto muito ), mas tinha um ou dois metalzinhos tambem e um outro estilinho, combina bastante com o jogo! :) End of the road for me</h3> Essa semana eu terminei o game com todos os carros e todos os upgrades do modo carrer! Para fechar o jogo 100% só faltou pegar todos os carros de policia num modo fora do modo carrer, mas esse modo é meio chatinho e eu não estou com muito saco de jogar ele, portanto as minhas brincadeiras com o Most Wanted terminam aqui. Aqui fica tambem o motivo de eu não curtir muito jogo de corrida... Agora eu cheguei no topo, e sou o mais procurado... E aí? Não veio nem um vídeo legal, nem alguma coisa divertida, nem um congratulations, simplesmente terminou, ganhou tudo e acabou, posso ficar correndo ainda em qualquer pista, acho meio vago isso. Aí ficam as minhas considerações sobre o jogo! ;) Ir além do básico tambem é gratis Unknown — Thu, 11 Dec 2008 00:00:00 +0000 Faz um tempinho que eu estou querendo fazer um post seguindo os moldes da campanha do Marco Gomes</a>, que também gerou o post do Diego Eis</a>, e finalmente consegui um tempinho para expressar também a minha opinião nesse assunto! :) Conheço muitas pessoas que fazem faculdade relacionada a programação, mas não aplicam o que estão vendo por lá, acham que já estão fazendo demais em ir para a faculdade e ficar lá no tempo em que o professor está falando...Ou seja, essas pessoas não estão indo a faculdade para aprender algo para colocar em prática, eles estão lá simplesmente para "passar de ano". As vezes não é nem tanto com faculdade também, tem pessoas que não fazem faculdade, querem ser programadores, mas tem aquele pensamento: Ahh... Eu preciso de uma oportunidade para aplicar os meus conhecimentos </blockquote> A internet está aí para isso! Você pode ter uma gama monstruosa de ferramentas para brincar se quiser, tantos livros gratuitos para aprender/melhorar sua programação, tantos projetos Open Source para contribuir, cursos on-line gratuitos para fazer, mas o sujeito quer "ganhar uma oportunidade" sem nem mesmo merecer ela. Esse tipo de pessoa para mim não é programador! Gostaria de aprender a fazer isso por que é muito foda, mas parece muito difícil, então vou fazer o XY que é mais zuadinho mas é fácil </blockquote> Apertar parafusos também é fácil...Se as coisas fossem fáceis colocaríamos robôs para fazer... Estou trabalhando na empresa XY mas já estou cansado de lá...Cansei de suporte técnico, eu quero é ir programar, mas sem experiência fica difícil </blockquote> Vá e consiga sua experiência sozinho, faça um site e mostre quando for na entrevista, como que o cara quer ter experiência sem fazer nada.... Putz...Não conheço nada de Linux esse sistema é uma merda... </blockquote> Esse é um candidato perfeito a ser um ótimo programador não é?! Primeiro já caiu numa contradição, por que se ele não conhece nada, como sabe que é uma merda? E outras, não quer nem conhecer um sistema diferente onde ele terá suporte nativo a várias linguagens, e não só isso, só o fato de não querer aprender algo gratuito e importante para a carreira já faz dele uma pessoa pouco interessante! Portanto, vamos a alguns pontos importantes: Invista tempo em aplicar o que você aprende na faculdade, ou caso não faça faculdade, corra atrás de coisas para estudar e aplique elas também. Procure coisas diferente para saber, afinal, quanto maior a sua gama de conhecimentos mais difícil será você dizer para alguem: "Não sei nem o que é isso". Desenvolva coisas úteis e mostre seus código na internet, isso ainda vai ser muito útil para você (tanto para aprendizado quanto para apresentação pessoal). ). Para finalizar só quero frisar uma frase do post do Marco Gomes que émuito interesssante e resume muito a minha opinião: "Você pode mudar sua vida, e até mudar o mundo, com o mesmo equipamento que usa pra ficar o dia inteiro no orkut trocando recadinhos com as peguetes" Como são os primeiros passos de um Linuxer Unknown — Sat, 29 Nov 2008 00:00:00 +0000 Nesse post eu vou contar um pouco de como são os primeiros passos de alguem que quer mesmo brincar com Linux. No caso vou falar como eu comecei com o Linux! Vamos lá! :) Eu sempre ouvia falar de Linux quando eu lia Livros sobre segurança e tudo mais, portanto sempre tinha vontade de utilizar... Meu primeiro contato direto com Linux foi em 2004, mas nessa época eu ainda era bem fanático por jogos de computador, o que me fez continuar no Windows por um tempo. No meio de 2005 eu comecei a utilizar a minha primeira distro de Linux, que foi o Kurumin</a>! Ele seguia o mesmo caminho que o Ubuntu</a> segue hoje, que é facilitar o Linux para o usuário doméstico, ele era até bem legal, mas na época eu sofria muito por ter internet discada, e nos tempos com Linux é muito difícil, principalmente para um usuário inexperiente. Na época eu não podia ter banda larga por vários motivos, portanto a única solução era a discada mesmo, então eu tentei várias formas para sobreviver com Linux assim, testei várias versões do Kurumin, peguei vários softmodens emprestados para saber qual funcionaria bem, comprei um hardmodem USRobotics para ver se conseguia fazer funcionar 100%, mas não adiantou muita coisa... Mesmo com os meus problemas com internet discada, essa foi a época que eu aboli de vez o Windows e fiquei somente com o Kurumin na minha maquina, pois eu descobri que o Kurumin 4.2 funcionava com meu moden Intel537Ep. Posteriormente quando comecei a fazer ETE</a>, e lá eu tinha matérias como C# e VB.net onde eu tinha que usar o Visual Studio</a>, portanto precisava do Windows instalado novamente, e ainda por cima consegui meu primeiro trabalho com programação (uhuu!) trabalhando com ASP e VB.NET (duuhhp) , portanto fui obrigado a voltar para o Windows, e mesmo com dual boot o Kurumin um pouco de lado. Durante a ETE tive um trabalho sobre o Linux para fazer, onde tive que conhecer melhor o Kalango... Instalei ele, dei uma brincada, mas realmente não gostei da distro... Se fosse para utilizar o Kalango eu ficava no Kurumin mesmo. Durante esse tempo eu tambem tentei brincar com o Slackware, mas devido a internet (novamente) eu não tive a menor chance contra ele... Minha experiência era muito pouca para poder fazer funcionar um modem para acesso discado no Slack. :P Quando finalmente consegui ter internet banda larga eu já resolvi extrapolar para aprender e usar o Slackware de vez! :) Foi a época que eu penei bastante para aprender coisas simples que eu não tinha noção e que o Slackware deixa para vc se virar ao invés de tentar fazer com alguma fórmula mágica, e esse foi o principal motivo de eu usar Slackware, para saber onde e porque as coisas acontecem. Agora com a internet banda larga (não tãão larga assim) funcionando ficou bem mais fácil de usar Slackware, afinal, se tinha alguma coisa que eu não sabia era só pesquisar sobre o assunto ou perguntar para o pessoal da comunidade, e assim eu conseguia resolver os pequenos probleminhas aos poucos. Agora que já conhecia um pouco mais e minha experiência tinha aumentado um pouco eu resolvi testar outros Window Managers! Eu queria algo mais leve que o KDE</a> (que eu sempre utilizei), queria algo minimalista, algo simples, curto e grosso, e foi então que eu achei o Fluxbox</a> e descobri que eu poderia ter um Window Manager totalmente configurável, leve, bonito (se você quiser deixá-lo assim) e funcional, portanto defini ele como meu WM principal e ainda uso só o Flux até hoje no Slackware. Durante o final de 2006 e o meio do ano de 2007 eu utilizei pouco o Linux por 2 motivos: Devido a ETE que pedia muito coisas de Windows e portanto eu não gostava de ter de ficar trocando de sistema operacional a todo momento.</li> Comprei um Palm T|X e na época eu estava começando a brincar com o bichinho e usar o Palm Desktop</li> </ol> Nessa época tive um problema e formatei o computador por completo, portanto perdi meu Slackware que estava configuradinho e perdi meus arquivos do Windows, portanto tive que refazer todas as instalações, mas eu estava sem tempo para configurar o Slackware novamente para deixar como eu queria, portanto ele ficou de lado até que eu conseguisse tempo novamente. Com o fim do meu curso na ETE em julho de 2007, meu tempo retornou e pude voltar a brincar com o Slackware novamente, mesmo trabalhando com tecnologia Microsoft, sempre que eu podia brincar com meu Linux eu brincava, e deixava o Windows para trabalhar e para video game. Em 2008 eu iniciei meu curso de Sistemas de informação na Fundação Santo André</a>, e nos primeiros dias me vem uma pequena decepção que eu não esperava...As minhas aulas de programação são em VB.net novamente, portanto eu não tenho como fugir do windows por mais 1 ano...E o pior de tudo, pensei que fosse encontrar bem mais pessoas com mente aberta para coisas diferentes, filosofias diferentes, mas não foi bem assim que as coisas de aconteceram...Mas enfim, não é o assunto desse post ;) Durante esse ano que eu pensei que ia deixar o Linux de lado novamente, mas aconteceram muitas coisas legais, como por exemplo eu mudar de emprego (uhuu!) e agora trabalhar com tecnologia</a> Open</a> Source</a> (uhuuu!)², e portanto eu tenho meu Slackware instalado no computador do trabalho, e comprei um notebook, onde instalei o Ubuntu linux, tanto para conhecer como também para facilitar algumas coisas, assim eu posso conhecer tanto o modo Slackware de fazer as coisas como o modo rápido, fácil e mágico do Ubuntu. Hoje vivo feliz e contente brincando com meu Slackware e meu Ubuntu, e não preciso mais do Windows para nada além do que é pedido (Visual Studio...) na Faculdade, e isso me deixa muito contente. No fim das contas o que esse post vem dizer é o seguinte: Se você acha o Linux legal use, persista, conheça coisas diferentes, caso não seja possível nesse momento tudo bem, mas deixe na sua lista de coisas a fazer e assim que possível volte, que você vai descobrindo a quantidade de coisas legais que você pode ter nesse sistema. Espero que isso tudo seja útil para alguem! ;) Keep going in the good way!

Places</h2> I only had one day to explore the city, and I was already sick, so there won't be many things this time. We had a paid guide for a walking tour and he helped us to find some different locations and skip lines.</p>

Food</h2> I always do a disclamer here because I'm not very into finding good food in places. I mostly ask for some recommendations and then eat whatever is easy and not expensive after this. I'm going to add here the places I went and the ones that people recommended me to go.</p>

Coworking</h2> We sayed in the [TBD] coworking space, near our hotel and the Galata tower. The host was very friendly and helped us feel comfortable at the place. They have coffee and tea available for everyone, along with some small sweets.</p>

Post-conference</h2> There's one famous happy hour they do after the first day when people visit the city museum, which is amazing.</p> They also had some sort of happy hour after the second day of the conference, and I used this time to meet new people.</p>

Miami

Airport</h2> Nothing to complain about the airport, it worked well for me. The location is not that bad, and I could get an Uber to places I wanted to visit in the city. I got there in ~20 minutes.</p>

Places</h2> I decided to got to Miami beach because... why not? 😅 It's the only place I heard of and I wanted to visit it. It was ~20 mins by Uber from the airport.</p>

Food</h2> Margheritaville</strong>: This place is inside the Bayside Marketplace. It has a view for the ocean if you decide to eat at the bar. It was a great experience. Spent ~$45 for a burger and cocktail.</li> </ul>

St. Louis

Airport</h2> The airport is quite small, but I have nothing to complain about, everything worked well for me. My flight was 5AM, so I had to arrive there ~3AM to be able to get my flight. I think this is a tradeoff of a small airport/city.</p>
