Here is a list of projects I have been working on, mostly in my spare time. For work-related stuff, see my list of publications. Some of the projects described here are mine entirely, on some I am merely helping.
This is the project where most of my project time is spent. Its a blog about parallel programming and has become fairly well-known in the community. I post about one article per week, which is a fairly low frequency for a blog - but since I am doing it regularly and my articles are usually quite unique, my readers seem to find it OK (nobody has complained yet :-) ). It has enabled me to learn a whole lot about writing, web-programming, PHP, wordpress, wordpress plugin development and even a few things about making money online (although the last part has not taken off yet :-) ).
A small page in German, where I describe my experiences with webhosting in the USA, especially with my provider Hostgator. There are many hosts in the US with way better features than most German providers and because the Euro is a very strong currency at the moment, they are even very affordable. The site also contains some general tips on webhosting, along with the reasons why I chose Hostgator. Many links on the site are affiliate links that make me a little money as soon as someone trusts my advice and signs up with them.
This project is part of my dissertation. Homepage and description will follow soon...
I am one of the founding fathers and organizers of the Lindencon, which is the biggest role-playing convention in the eastern part of Germany. Every year, about 150-200 people meet in a beautiful location in Leipzig to enjoy their hobby. My main responsibility is the website of the event, along with managing the registration system (which has evolved into a backend-system of its own) and the distribution of the games across the location. Of course, on the Lindencon-Weekend this is all moot, as every member of the organisation team helps whereever help is needed...
Not at all a project of mine, as all I am responsible for is the website and the registration-backend. I usually don't do websites for anyone except for myself, because I hardly find the time for my own projects. This one was different though, because a very good friend asked me to help him and of course I am always willing to lend a hand to good friends. The template used here is intentionally very dark and has a dirty look, since the site is about a tavern for the undead (once again, at a live roleplaying convention).
