I wanted to use GoCV for one of my projects (to find and extract paper documents from within a larger scan), without permanently having OpenCV on my system. This seemed like a good example use-case to demonstrate a couple of Nix commands I like to use, covering quick interactive one-off dev shells to fully declarative, hermetic, reproducible, shareable dev shells.| Michael Stapelberg
In this article, I want to show how to migrate an existing Linux server to NixOS — in my case the CoreOS/Flatcar Linux installation on my Network Attached Storage (NAS) PC. I will show in detail how the previous CoreOS setup looked like (lots of systemd units starting Docker containers), how I migrated it into an intermediate state (using Docker on NixOS) just to get things going, and finally how I migrated all units from Docker to native NixOS modules step-by-step.| Michael Stapelberg
