26C3

Posted in open source, privacy by elisehuard on January 1, 2010

I’m not quite sure how I ended up at 26C3, but I had a blast.
From what I gather, the Chaos Communication Congresses are gathering of geeks and utopians (or both), around security, privacy and hacking. And LEDs.

We arrived the night before the start of the conference. We were lucky to have our places in advance, because when we went to retrieve our bracelets, people were queuing up to get their places.

The location of the 26C3 (and a few previous ones) is fantastic. The Berlin Congress Center is a graceful example of 70 architecture of the 2001 welcome to the future category. It’s basically a bloc containing a cylindrical structure – the outside edges are the corridors, the inside disks are rooms. Saal1 (under the cupula) in particular is phenomenal, but the rest of the building has lots of charm too.

The principle is that groups and projects book a table (or two), and gather round that table to sit, and hack, or misc. I ended up at the Debian table (‘debianist by association’), thanks to the friends I was traveling with. There were tables with people having brought really old hardware, tables with robot arms, and everywhere laptops.

At 26C3 they set up all kinds of networks. The building is properly wired, and there were a few wifi network that worked reasonably well. Then there was the DECT radio network, which means everyone was walking around with your average domestic chordless phone (DECT radio for those in the know). They even set up a GSM network which didn’t work too consistently, but was way cool nonetheless: instead of vodaphone et al. you had an in-house network which even worked for normal domestic calls !

The talks were streamed live. I didn’t attend that many talks in person, as the rooms were really packed. Besides, knowing that the conference recordings would be available later also made it less of an incentive to try and pile in. The talks I did attend/listen to were fascinating.

One talk I attended was about stylometry, or how you can in certain situation detect who’s the author of a text by the word choice, grammar, etc. Which obviously means danger for whistle-blowers publishing anonymously against an abusive employer or an oppressive regime. The author was trying to ‘attack’ those techniques, by trying pastiche or obfuscation. Another talk was about intelligence support systems, and their use by all kinds of organization. I also followed a talk about attacks on PKI, which is interesting since my current work is all about PKI.

The ground floor was catering mostly, and the lower floor was the hardware hackers floor. The catering floor was visited many times to get a dose of Club-Mate. Mate is a naturally caffeinated kind of tea leaf from South-America. Club-Mate is a soda version of that, and quite tasty and effective, as energy drinks go.

Then there were all the cool toys ! You could buy kits of electronic circuits to assemble yourself. I bought and assembled the TV-B-Gone kit to switch off tv’s, which worked, and a dotblox64, which lots of LEDs, which doesn’t yet (because of slightly shoddy solderwork). There was a group making helicopters, and a group building and programming LEGO robots to fight against eachother. Geek heaven, or what.

lockpicking class
I also had a go at lockpicking, though I must admit that I miserably failed at that, being quite clumsy (the instructions in german might not have helped). The stories of the instructor (from lockpicking.org and the lockpicking club of Berlin) were interesting. He explained about how locks usually worked, about different kinds, and the pleasure and effort to figure it out. He also bragged a little about his exploits, of course: seems he has a master key of the Berlin underground, and the Berlin public toilets.

The general vibe was one of love for freedom. Lots of subculture represented, though obviously the overarching one was geekiness. No judgments, no rules, things were built for fun, not necessity. A fairly mixed audience, a slightly subversive but enthousiastic spirit. I had a good time, and will enjoy watching some of the remaining talks at home.

    Thanks for writing about your impressions!

    I enjoyed the streams, and now the conference recordings, but I would have preferred to be there. Hope next year I’ll be “mit von der Partie”. Your text makes me even more curious.

    PS the URL to the conference recordings seems to require http (not https).

    It is my son’s birthday in the near future and I feel that the article has made my thoughts up regarding precisely what I am going to buy him.
