Recently I had an interesting conversation with colleagues on the topic of
writing tests for code. In particular, it was about tests for hotfixes that need
to be deployed as soon as possible. In this post, I’ll leave the results of that
conversation aside and focus on what it inspired me to think about. On the
question “Why do I write tests for code?”
A week ago my friend Pablo and me released the very first episode of Code &&
Beyond. None of us had any experience in podcasting or ever worked with voice

Recently I realized that a professional career started for me twenty years ago.
However the journey of becoming a software engineer begins much earlier, and
the first sparkle of interest wasn’t created by a computer itself.

This post is written in Vim. I use this editor for the last five months, but it’s my sixth attempt to tame it. Let me share a few lessons learned and reflect on the experience.
A software engineer career started for me in 2001 when I joined a tiny start-up
company as a junior developer. Since then I was working in different companies
and different roles. There is one thing that is still every time magical and
makes me feel like a kid.
Not being able to leave an apartment for a couple of weeks due to a COVID-19

video games. That’s how my son Tim and I discovered an amazing game - “Alba: a
wildlife adventure” from ustwo games.
As a cloud platform Amazon Web Services (AWS) offers over 175 services. If you pay attention, you’ll notice that people often do mistakes in the names of these services. For example they say Amazon Lambda instead of AWS Lambda, or AWS DynamoDB instead of Amazon DynamoDB.
While it’s important to use correct names and terms, it’s also hard or at least tricky sometimes. I’ve created a little tool to help with that and made it open source.
If you don’t know LGTM is an initialism of “looks good to me”.
A few days ago, while going through my Twitter timeline, I spotted one tweet that turned on the bulb above my head. I was instantly inspired! 💡
Today it is hard to image an app or a website on the internet that does not require authentication. Usually a sign-up form have at least two fields — email and password. That immediately brings two problems:
