Chattering excitedly in a mix of English and German, people in
t-shirts advertising secure operating systems discussed things like
smart phones (called "handies" in German), techno music, and
politics. When registration finally opened, around 7 PM, the harried
volunteer behind the counter couldn't find my name in the system and
finally admitted, in German-flavored English, "It is a bit chaos."
The conference runs 24 hours a day, with many people spending the
night on the conference room floor in sleeping bags, so he advised
that I come back for my badge around 3 AM.
