Open Source Contributions

Mercurial

I contributed to the Mercurial distributed version control system:

• I co-developed an efficient distributed protocol for determining missing commits,
• created the patch branch extension, and
• wrote a German introduction to Mercurial .

and mentored others:

• Nautilus integration for TortoiseHg. Completed.
• Partial Cloning support for Mercurial, that is, cloning a subset of files (narrow clones, co-mentoring). Aborted.
• Shallow cloning, that is, cloning only recent history. Aborted.

Own Projects

I also created a few projects:

• Remote controller for the Hoval Ultrasource heat pump written in Go for the Raspberry Pi (MIT).
• Abacus Formula Compiler - extract computation models from spreadsheets and compile directly to JVM byte code (for Abacus, commercial and GPLv3).
• JCite - cite Java source code directly from unit tests into your documentation (BSD).
• JDepChk - check dependencies in Java virtual machine (JVM) class files (BSD).
• EDepChk - integrate JDepChk with Eclipse (BSD).
• Rextile - build XHTML documents and entire web sites – like this one – with ease (BSD).
