The Chaos Communication Congress is the second largest hacker convention in the world (after DEFCON). It is organized by hackers from the Chaos Computer Club and people close to it. If you are interested in computer security or the impact of computers on society, you should definitely try to get some tickets!
Tickets are pretty hard to get, anyone going there?
