EuroPython in 2018 was my first international conference. After five years, I eagerly joined another EuroPython. I hopped on a night train and woke up with a view of beautiful sunflower fields near Prague. With the conference starting the next day, I had some spare time to explore the charming city. In the evening I […]

We’ve been using NixOS for a few years, and it has proven to be a stable and reliable OS. More importantly, it’s declarative and reproducible, which is one of the main reasons we decided to migrate ~700 of our Ubuntu servers to NixOS. However, it has a few downsides, and one of the biggest ones […]

It’s good to be back! The past two PyCons in Japan have been online, so it was nice to be back in person where you could actually enjoy the little things in between talks like meeting and talking to other attendees and exhibitors. This year, the event took place in Ariake, Tokyo, which is home […]

After three years, we finally got a proper IRL NixCon. Since the Nix community is not the biggest one, it was nice to talk about Nix for three days (two at the conference and one at the sprint). We heard many interesting talks and answered a few important questions. So let’s start with the most […]

I’ve been babbling on about testing for a decade now. Here’s a quick list of pytest plugins I use in most of my Python projects:   pytest-cov – pytest integration for the wonderful coverage tool by Ned Batchelder. pytest-mock – pytest integration for the unittest.mock library. pytest-instafail – Print out the test failure as it […]

At the beginning of the month, I made a quick road trip down to Florence for this year’s edition of PyCon Italia. I try to never miss a chance for a conference I can *drive* to, and Tuscany is just such an awesome place to visit, it really was a no-brainer. The organizers have been […]

The mind has not yet completely recovered from all the brain explosions that happened during OceanSprint 2021, and I was already planning the next one. I’ve never organized two sprints so close to each other, but it worked out great! Domen and I knew exactly what we were getting into, most of the vendors we […]

Three months after we closed the sale of WooCart, our project that was gonna “make it big”, I am ready to review the full financial consequences of our failure: $700k loss.

Whether we know it or not, we build things based on the work done before us. This is true in every aspect of life, and programming is no different. Every few weeks, we (at Niteo) have a developer session where we (developers at Niteo) talk about new things we learned, cool libraries/tools we discovered, etc.Last […]

At Niteo, we are using nix-shell to build isolated development and production environments. We deploy production as a Docker image on Heroku. Recently, I’ve noticed that Pareto Security dashboard app deployments have been very slow. Almost 10 minutes, even more on a busy afternoon. Most of the time was spent in copying files around, as […]
