Stats for March, 2017

Back to work this month. :) After one month vacation, I got back to my routine and got some good results this month. Books Added three more books to the list: I have to note here that Mastery is one of the best books I ever read. Both Mindfulness in plain English and The Urban Monk are about meditation and how to live a minimalist life. Articles I’m still trying to find a way to track the articles I read.

Stats for February, 2017

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 Continuing my goal to read 30 books this year, I read two books this month: I had plans to visit Amsterdam and Oxford during my travel. Because of that I decided to read the story of Kullervo, which mention a lot about J.

Stats for January, 2017

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 from Matthew of Books My goal is to read 30 books this year, so I must have an average of 2.

Oxford for Tolkien fans

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 I decided to travel around some countries in Europe and UK.

FOSDEM survival guide

TL;DR: It was my first time at FOSDEM and it took some time to feel comfortable, this post may help newcomers. As I mentioned in my previous post, I spoke at FOSDEM 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.

My presentation at FOSDEM 2017

This year my proposal to speak at FOSDEM 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.

Experiences of almost two years using Colemak

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, 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 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.

OSCON 2015

TL;DR I’ve been at OSCON this year (thanks to Locaweb) 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 (in portuguese). OSCON (Open Source Conference) 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.

New layout of PotHix blog

Welcome to the new blog layout of! :) 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.

Golang and 1.2 version performance improvement

I’ve started using Go last month and I really liked to work with the language. The project I’m working on is dead simple and just retrieves metrics and save on a redis server (the data will be analyzed by a different project that I’m working on). So I have 15 goroutines retrieving data constantly and I’m using just two native threads. I did some CPU profiling on the code using my current machine for Golang 1.
