Projects

Jyrki, a cyber fox, standing on floating platforms that display snippets of Ruby source code.  These platforms are arranged in a tunnel, where at the end of it a glowing bright red Ruby gem is floating.  Jyrki is pointing towards it, inviting the viewer to take a closer look.

I do a lot of things... so here is a small listing of projects or other stuff that's worth mentioning

A fun little plug-in for Qmmp that exports your playlist to a HTML file, similar to the ones Winamp used to create.

qmmp-macosintegration C++ Objective-C++

Another plug-in for Qmmp, this one lets it integrate better with the macOS desktop. It also makes the media keys (e.g. play/pause) work.

Philips® Hue™-related tools

mdlatex Ruby

droetker Shell

A static site generator written in sh(1). It’s really fast and only seems to work on FreeBSD (or at least with BSD userland). Not recommended for production use. I actually used it for this website before switching back to Jekyll… until I switched this site to FoxPage, of course.

JSONfs Ruby

Browse your JSON objects using your favourite file explorer. Because you never knew you did not want to.
