  • Boring Technology at Startups

    New technology is always exciting for us engineers. A new programming paradigm, a new programming language, a different library, a different database.

  • Is AWS Fargate The Future of Containers?

    I’ve been using Amazon Elastic Container Service (Amazon ECS) since 2016 and my team manages our EC2 resources through our internal PaaS.

  • Exceptions vs. Returns

    The other day Thiago Pontes shared a blog post with a few friends about exceptions considered an anti-pattern. I have a different opinion about exceptions and I thought it’d be interesting to write a blog post about it. I think exceptions are a great feature and the lack of it...

    Can Programmers be Powerlifters? Of course! Two years ago I have never had a gym membership and was pretty much a sedentary; I played basketball in high school and once in a while with friends in Rio de Janeiro. After I started dating my wife I started working out in...

  • Rethinking Education

    I dropped my bachelor degree in 2010 while I was in the second semester; my classes were boring, some teachers were not updated to what is happening in the industry (some not even in the academia), and most of the students were not interested in learning, they just wanted to...


  • The Practice of Programming Book - first chapter review

    Last year I read the famous The Practice of Programming book, by Brian Kernighan and Rob Pike, and it was a kind of déjà vu; it is a Clean Code book from the 90s! I decided to get my paperback and write some thoughts about the first chaper, Style. 1.1...
