The first day was not really interesting -- the lectures were actually pretty boring, and hardly anything was going on. Not much to tell about it.
On the contrary, the second day was quite interesting. First of all, I held my lecture on network intrusion detection with cinderella. Many people attended my lecture, and tent A was almost full, although the lecture was at "high noon". The questions from the audience were quite good, and nobody was out to flame me. Unfortunately, I rushed through the lecture too quickly, so it actually took only 40 to 45 minutes, including the Q&A with the audience.
Other lectures I went to was the one about software patents by FFII, the SIMD hacking lecture by Felix von Leitner, the Hacker Jeopardy that was organized by `Sec` and the pretty weird Nazi UFOs lecture.
After that: social events! We partyed with the quintessenz guys, and it was definitely a good party. During that, some 2600 guy told us that there was a huge orgy going on in the cypherpunks tent, so we went there. All we found were about 10 people sitting around and chatting (IRL). Then, they showed us a pretty funny website: www.haXXXor.com. There you can buy a DVD showing hot women reading manpages, configuring Apache and describing installation from source while taking off their clothes. They showed this DVD at the OpenBSD tent. After that, we went back to quintessenz, had another beer, and then I went to bed.
