Here is a list of some of the projects that I’m involved with that actually might be useful to others.
I wrote a series of blog posts in which I document my efforts to understand and possibly manipulate the firmware of Korg’s Wavedrum. The PCB is easily accessible and exposes big connector pads as well as a microSD card—an invitation to play with the hardware.
The project page is the best place to get an overview and to see the current status. It contains links to the sources of any software artifacts I create in the process.
GNU Guix is a novel package manager for GNU systems. In Guix a package is treated as a pure function whose output is fully described by its inputs (its dependencies). I’m packaging lots of bioinformatics software when I’m in the office and audio tools when I’m off work.
The Guix package manager forms the foundation of the Guix System Distribution (short: GuixSD), which is the GNU system I use on my laptop.
Libertree is a collection of software to build social networks. The core components include a web frontend application and an XMPP backend component that will work with any regular XMPP server.
I was one of two core developers for about three years and hosted the second public node. The network isn’t very active and development has slowed considerably. I’m no longer interested in traditional www-based social networking applications and am thinking about using Gnunet for pseudonymous social networking purposes.
I have ported two VST instruments to the LV2 plugin framework, because I missed them after my move to GNU/Linux.
