I am a network and systems engineer currently working at FI-TS and this is my github profile.

My current most liked language is go, previously this was perl. I used to program in a bunch of other languages like C, python or ruby. I do almost all my work with emacs, for which I wrote a couple of emacs modes.

The projects I am currently working on are:

• Golsky: a golang implementation of the game of life, supports RLE patterns, saving and loading, drawing, zooming and is controllable using key bindings.
• Openquell: a 2D puzzle game using ebitengine, arche and LDTK. Not (yet) opensource. Play it online
• kageviewer: a live viewer for shaders written in Kage, similar to glslviewer
• gfn: a cli tool to generate fantasy names for games and stories
• kleingebäck: a tool to backup kleinanzeigen.de ads.
• yadu: a go log/slog handler using a mix of log lines and yaml.
• rpnc: a commandline and interactive programmable reverse polish notation calculator
• tablizer: a console table manipulation tool
• ephemerup: a ephemeral file upload system with rest API and commandline cli

The most fun projects I did in the past:

• pretty curved privacy: a tool to encrypt and decrypt data at rest using eliptic curves for the commandline.
• diceware: a diceware password generator, which I use regularly.
• udpxd: a udp proxy supporting v4/v6 conversion.
• twenty4: a self-made cryptographic algorithm I created just for fun.

There are a couple of perl modules I am still maintaining:

• Config::General: a widely used configuration module.
• Data::Validate::Struct: can be used to validate recursive data structures.
• Crypt::PWSafe3: a module to read and write passwordsafe.net files.
• leo: a commandline interface to https://dict.leo.org.

I also maintain (and use daily) the FreeBSD jail management tool jaildk. Another fun shell script is goupdater, which I use to install and update all those go binaries which are avaliable as direct downloads.

And finally these are some emacs modes I maintain (and mostly use):

• novel-mode: a simple mode to use emacs as a comfortable screen reader.
• mark-copy-yank-things-mode: Mark, Copy and Yank Things Emacs Minor Mode.
• autoscratch: Automatically switch major mode from scratch.
• viking-mode: Kill first, ask later - an emacs mode for killing things quickly.

My current emacs configuration can be found here: dot-emacs.
