I'm a systems administrator at the Max Planck Institute for Polymer Research. My focus are UNIX™-like systems, e.g. Linux and BSD Unices and services running on them.
I'm actively exploring the OpenBSD operating system: using it as my primary operating system, reading parts of the source code, trying to understand how things work together.
I like Lisp-like programming languages. When possible I use some Scheme in R7RS mode (e.g. Gauche Scheme) or Emacs Lisp.
At the same time I have a penchant for POSIX shell and POSIX AWK.
For exercise I learn a bit of Wudang style Taiji at the “Weißer Kranich”.
