23C3 - Day 2, 3, 4


A bit late, but here are some more random notes from 23C3:

  • I didn't see much of the surrounding programs, workshops, projects etc. of the congress, as I was attending tons of lectures all day long. Most of the time I was even recording a lecture from a different room via DVB-T (for later viewing) while watching a "live" lecture in the room where I was sitting with my laptop.
  • I met some LinuxBIOS people at the congress (no hacking, though). However, Peter Stuge did a nice 5 minute presentation on LinuxBIOS in one of the Lightning Talks sessions. A video should be available soon.
  • Like ca. 1000 other people, I bought some of the Sputnik active 2.4GHz RFID tags for tracking and hacking purposes. There's some data mining going on using the data collected during the 4 days of the congress. This is an experiment to demonstrate the possibilities of tracking and surveillance with today's technology in order to hopefully make the people (and politicians) more aware of the associated threats and risks... Btw, the hardware is licensed under a Creative Commons license, the software is GPL'd, so feel free to contribute!
  • I barely slept 2 hours a day during the whole conference, so I needed lots of time for recreation afterwards... But it was very well worth it!

23C3 - Day 1

Some observations while on an 8 hour (night) train ride to the 23rd Chaos Communication Congress (23C3) in Berlin:

  • DVB-T doesn't really work exceptionally well in a train that's moving at 200-300 km/h.
  • I also had almost no GPS signal in the train either, not sure why. The speed should not be a problem as GPS is supposed to work at high speeds (unlike DVB-T). I intended to create a nice visualization of all wireless networks on the way to Berlin (using Kismet and GPSDrive), but... well, without GPS data that's not too funny.
  • They have coffee in the train! Not exactly cheap, but it's there.
  • Having a ticket for waggon 23 of the train is somewhat... fitting.

There's a lot of press coverage about the congress already, so I won't repeat all of that here. Just let me tell you that there's a tremendous amount of great lectures, many of which I have attended (and they're also streamed on the web, as well as broadcast via DVB-T locally here in Berlin, which is great!).

22C3: Final Stuff

More Bandwidth

OK, I will make this short because a gazillion of other people will probably blog about the 22C3 for several days or weeks to come... Today (last day) I only attended one talk — Bluetooth Hacking - The State of The Art. Funny stuff you can do with Bluetooth...

All in all it was a great conference. Get the proceedings or browse the list of talks (most of them have PDFs attached) for more details. Videos of all talks should be available anytime soon (I hope!).

Oh, and the 22C3 is probably the only event where you will see such signs (attached to walls by the congress staff!)...

Going to 22C3

I'm heading towards Berlin in a few hours in order to attend 22C3. I'm not sure if/when I'll be able to blog or read/answer emails there, but I'll be back in a few days...

Lots of 22C3 stuff

Tim Pritlove Jens (argh, need some sleep!) from the Chaos Computer Club (CCC) has asked for more english blog posts about 22C3, the upcoming hacker conference in Berlin. So here you go.


The 22nd Chaos Communication Congress (22C3) is a four-day conference on technology, society and utopia. The Congress offers lectures and workshops on a multitude of topics including (but not limited to) information technology, IT-security, internet, cryptography and generally a critical-creative attitude towards technology and the discussion about the effects of technological advances on society.

The congress (sub-titled "Private Investigations") will be held from December 27th to 30th, 2005, in Berlin, Germany.

Some noteworthy bits and pieces:

This is gonna be one of the highlights of this year, I'm really looking forward to the congress.
