Hello Hackers, Nerds, Geeks, Freaks, whatever!
A quote from
http://events.ccc.de/congress/2009/wiki/WelcomeThe 26th Chaos Communication Congress (26C3) is the annual four-day conference organized by the
Chaos Computer Club (CCC). It takes place from
December 27th to December 30th 2009 at the bcc Berliner Congress Center in Berlin, Germany.
The Congress offers
lectures and
workshops on a multitude of topics and attracts a diverse audience of thousands of hackers, scientists, artists, and utopians from all around the world. The 26C3s slogan is "Here Be Dragons".
It's my tradition to go to Berlin between Christmas and New Year's Eve.

If you don't want to go to Berlin, it's possible to look the lectures live via webstreaming (details should be published somewhere in the congress Wiki), either at home or at an alternate location (Because the Berliner Congress Center is always very crowded they start this year with a distributed congress: "
Dragons everywhere" is a list of locations with public viewing of the webstreams in realtime).
After the congress there will be video recordings of the talks for downloading, and after some weeks there will be official recordings (
Recordings of the last year 25C3). Just in case you want to re-watch a talk, or you don't want to watch it in realtime.

I'm shure there are some talks which might interest you, just look on this
list of lectures.
And by the way: The congress has always a very fast Internet connection with public IP addresses for it's participants. Perhaps you will see increased network performance in your P2P or anonymous P2P network, or find fast public FTP-servers... Congress participants have many ideas for using this fat Internet pipe. Just look in the congress Wiki for information updates.
