I support the Free Software Foundation Europe (fsfe.org). Everything I code in my freetime is therefore published as open source software. If you are interested, you can have a look at my projects here. I also try to document interesting stuff on my blog.
Besides that, I enjoy gaming on everything 8-bit (C64, Atari 2600, NES etc.) or fantasy consoles (PICO-8, TIC-80).
Apart from computer related hobbies, I love analog photography, bicycles, reading and many more.
