Hi, I'm Michael. I am an information security engineer with many years of experience in information technology. My first computer was a Commodore C64 (1989), followed by an Amiga (1992) and finally, in 1995, I got my first PC. In 1998 I installed my first Linux distribution (S.u.S.E. Linux 5.3), moved to Debian in 2002, tried a lot of BSDs and Linux distributions but always came back to Debian.

Everything I code in my freetime is published as open source software. If you are interested, you can have a look at my projects. 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.

You can find my 3D designs here on Printables.

I am a licensed ham radio operator and member of the DARC. My callsign is DK1MI. You can find some information about my station on my page. I am mostly interested in shortwave operation as well as working satellites.

If you'd like to contact me, please send me a mail to or send me a toot on the Fediverse.
