I just moved my blog to geekshow.blogspot.com. Good bye, advogato!

In the last few days, the Ars Electronica Festival was going on. There were quite a number of interesting talks and panels. I especially enjoyed those about copyright, DRM, DMCA, intellectual property and all that stuff. Cindy Cohn was giving much insight on what's going on in the US regarding all that kind of stuff, and IMHO, she was definitely the highlight, and so thought many other people, because most questions that were asked by the audience were directed to Cindy.

After watching the panel on Tuesday, I sat together with Erich Moechel and Tim Pritlove, chatting a bit and listening to several quite interesting stories. Tim then showed us nice pictures from the Chaos Communication Camp, including a 360 degree panorama shot.

After that, I met Tamer, Kyrah, Thomas Warwaris and OJ, and OJ showed us parts of the AEC including an exclusive demo of the currently on-going port of Unreal Tournament to the AEC's CAVE.

Day 1 and 2 on the Chaos Communication Camp:

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.

Day 0 on the Chaos Communication Camp:

We arrived yesterday in Berlin, and stayed at Sven Guckes' place. We showed us all the important places in Berlin, which was quite interesting.

Today, we went to the camp ground in the early afternoon. The camp ground, which is located 30 km away from Berlin, in Altlandsberg, is beginning to fill. We are staying with the guys from quintessenz. Hopefully, some other guys from at.linux and people from CNGW will arrive at midnight.

Currently, most people are still building up their tents. So, the camp will hopefully fill tomorrow.

Yesterday, I took snort's TCP state machine, translated it to Ruby, and built it into cinderella. So, finally, I've got a nice decent state machine that is quite fast (faster than my own, broken one) and work's correctly.

The slides about cinderella are already prepared, so I'm already looking forward to doing my lecture at the Chaos Communication Camp. (I'm mentioning this so often, see how excited I am? :-)

Recently, my brother gave me a nice CD, "Music Monks" by a band called Seeed. Pretty cool reggae, ragga, dancehall. I can only recommend it.
