This month I did something I should have done a long time ago. I started learning Kubernetes. I already read a little bit about the internals and spend a lot of time reading documentation for Nomad by Hashicorp, younger, simpler sibling of kubernetes. Kubernetes is a whole another level of monster though.

I will be leaving my current job at and joining SumUp in June. Most likely remotely at the beginning but I plan to move to Berlin as soon as the situation permits. This was a huge decision and not an easy one to make. I like, the team, the people, the job. The thing is, there most likely won’t be a better time than now and this is an opportunity I would be a fool not to take.


Not very often, especially in these times, you get the opportunity to set foot (or a wheel) abroad. So when I was approached by a friend with the offer of flying to Mallorca for 10 day cycling trip I accepted it without much hesitation. To be honest, I was quite nervous because my road cycling experience until than consisted of around 400km in 3 months. It didn’t help much either that I would be in a company of experienced riders with track record of years with over 10,000km and multiple wins on Czech as well as foreign races.

It goes without saying that the trip was intensive and demanding but to my surprise my legs held quite well. In the 10 days on the scenic island of Mallorca we rode 1097.86 km with average speed well above 30 km/h and grand total of 12,171 vertical meters. I saw the most remarkable sights such as Formentor and the bay of Sa Calobra (this one still hurts).

Overall, and in simple terms, I loved it. In a company of great people the suffer fest turned into one of the best vacation I ever had and I hope there will be more in the future.

The act of note taking

Robin Cussol, colleague of mine, has this well written and highly informative blog. In his 2020 year review he mentions a habit that I wanted to implement for quite some time: note taking.

In the online world we are surrounded with vast amount of information on all the possible subjects. News, social media, pictures, even videos are all build to be consumed in great quantities, fast, and without many thoughts. Yet, we prosper the most by diving deep into the things that we enjoy or that we want to learn.

Taking notes forces you to slow down. To better consider what you spent your time on. And for me most importantly there’s actually something left behind instead of me forgetting everything in matter of hours. Partially, I take my notes here, on this blog. Either in the form of book wrap-ups and reviews or in the form of short blog posts and monthly look-backs. I also have plenty of stuff written in Notion where I did a large cleanup recently and decided to delete as many links as possible. Instead, I tried to write short TL;DR of what I learned from the article and I plan to keep this approach further. Would be nice to do the same thing with the hundreds of opened tabs in my mobile web browser but that will take a few days so maybe another time.


  • Clean Architecture with GO. Even as my knowledge of Golang ecosystem grows, I am yet to find out, what the best application structure is for clean and maintainable APIs. For example the MVC pattern isn’t really applicable in Golang, rather structures similar to api <-> service <-> storage can be often seen, but those sometimes fall short of the needs as well. This article provides a nice take on alternative approach with schema controller -> interactor -> presenter where controller encapsulates the request logic, interactor handles the internal stuff you would normally find in the service and storage layer and presenter handles the transformation of the application models back into response returned to the user.
  • The Pirate Problem, what could be hard about five pirates dividing a treasure.
  • Nomad is workload orchestrator developed by Hashicorp. It’s wonderful piece of software that I started to dig into to better understand internal working of workload orchestrators and schedulers (think kubernetes).
  • r/WhiteHouseBets by Alex Danco, on GME, Reddit, reflexivity, and how internet enables crowds of people to focus their attention onto singular thing.
  • A Sea Story by William Langewiesche. After quite some time I found myself on an airport quickly looking for some read into the airplane. And where else to look for than in the archives of William Langewiesche’s. This time, another disaster horror story from 1994 when 850 people lost their lives on board luxurious ferry on the Baltic sea.
