I have been a user and advocate of open source software since I started playing around with Suse Linux in the 1990's. Over the last couple of decades I have used a lot of Linux distributions with a lot of different window managers and desktop environments.
During my college years at Technical University in Berlin I worked on the Open Source Annual.
At the moment my personal laptop runs Fedora with Hyprland. At work I use an Ubuntu workstation and a Macbook Pro with multiple Linux VMs.
