A week of work, and the world already turns out to be entirely a village: Dan Mosedale, lead developer on the Lightning Project (= Mozilla Calendar as a Thunderbird extension) spent a year at the University of Karlsruhe studying Informatik (computer science) in the early 1990s.
About a decade later, I started studying there, and I still am.
Looks like -- to use the words of one of my favorite professors in Germany -- Karlsruhe rules :)
