I have some apps written in Go, which I deliver as binaries for each platform using GitHub releases. Until now, I was doing it with a very simple shell script.

Watchub is a service that notifies you of people who followed/unfollowed you and starred/unstarred your repositories.

As a DevOps/SRE, I spent a reasonable amount of time dealing with metrics and alerts.

I have seen a lot of posts like this subject, but almost all of them were about stuff you should do and almost none of them reflected how I truly feel, how I want a product to be so I can “love” it.

Every now and then an active java-based project enters in a “dependency hell” state. That usually happens because people keep adding dependencies without checking what comes in transitively nor if that dependency is declared somewhere else already.

I’ve lost a considerable amount of time trying to bind those things together, so I decided to write this quick post about it, so others could also benefit from it.

This is the story on how I speed up my terminal load time.

booleans, am I right? What a wonderful piece of technology! They help us solve so many problems…

I’ve been wanting to write this for a long time, just to clarify my thoughts on the subject. Now, on vacations, I took a couple of days and finally did it. This is a personal opinion based on my personal experience and tons of books I have read, and I am not, by any means, the supreme holder of the ...

This is just a quick overview of how I did it in antibody’s homepage.

I gave a little intro on Docker and talked about when to use it or not.

In Go, it’s dead simple to get the value from an environment variable:

Or: how to ship your app in a <20Mb container.

There are a lot of Java API’s and Frameworks which rely in static methods and the sort. Arguably, this is a bad OOP practice, but lets not enter this particular subject just yet.

go build generates a binary for the platform you run it in. So, if I build antibody in a Linux machine - which uses Mach-O, it will not work in OS X - which uses ELF.

Learning Go was in my TODO list for a while, and finally I did something about it. This post contains some thoughts about it…

At ContaAzul, we had 31 Windows machines powering our Selenium tests - one running the grid and 30 more running clients. Needless to say, this is very expensive.

Or “what the hell is this Docker thing?”

Like my old post on git, this is somewhat a collection of useful Docker commands/tricks/whatever.

So, this week I attended to QCon-SP.

FYI: Like the previous post, this is a really quick tip.

Last years it becomes more and more common to work in different projects running on different versions of Java. There still some running on Java 6, and there are tons already running on Java 8.

FYI: Like the previous post, this is a really quick tip.

I know, everyone uses Travis. I have nothing against it. But in case you want to test and/or use Shippable, this might be just the guide for you. I will also show how to setup that nice tabs with the test and coverage reports.

Recently I saw a job description of a Brazilian company, more or less like this:

Estimated reading time of a post is a feature that became popular, I believe, with Medium.

Once upon a time, my blog was OpenSource. People liked it and forked it tons of times, but they never change some stuff (disqus, analytics).

I followed @mdo recent article “Using Sass with Jekyll”, and wanted to point out the results.

I will start this by quoting the bashstyle’s readme:
