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!
