A very short introduction to Nix 2024-03-04 This post is adapted from a talk I gave at my place of work to convince them to try Nix for managing our projects’ dependencies and deployment.

My first time on GTA 2023-06-27 A few weeks ago I was proven right. I didn’t like it. When I was young I played video games a fair amount. My history with screens started early on, when I watched TV in the morning before going to school. One day, I found an old Game Boy Advance with a cartridge in. I don’t remember...

Nix for Python, attempt number 2 2023-05-19 Last post we tried to make a Python project fully reproducible based on a detailed requirements.txt file. We ended up not managing to go the full Nix way, but we got pretty close. However, there are many ways to approach this, with language-specific tools getting published...
