Studied Computer Science at the University of Saarland. Currently work as Senior System Administrator at ETH Zurich. I'm a Debian Developer and Zsh Committer. I'm a board member of the Linux User Group Switzerland.
My favourites: Debian, Perl, Git, GNU Emacs, Zsh, GNU Screen, Aptitude.
While I'm probably more active on computer and IT related StackExchange sites, I also like the simplicity of old, often electronic-free cars: I own a Citroën 2CV, a Citroën HY, and a Citroën CX 25 Break as well as a Fiat Ducato based motor home (disguised as Citroën Jumper :-).
I also own two bicycles, a Brompton folding bike, a Radius Hornet I recumbent bike, and a Croozer Cargo bicycle trailer (for holidays, shopping, etc.).
