Others have mentioned it in passing and we tend to mention it as well. Anyway 30C3, the annual conference of the C3 hacker club, which is one of the biggest hacker conferences in the world and almost certainly the biggest one in Europe starts on the 27th of December. Most interestingly for many around here this year sees the return of sven and marcan (being joined by comex) with a console hacking talk, the "Console hacking 2008: Wii fail" talk back at 25c3 was widely heralded as the start of Wii hacking, similarly the 27c3 talk (also featuring marcan and sven) was what blew the PS3 wide open. This year they are looking at the Wii U and how its security was bypassed in near record time, though we should they are said to be downplaying things to avoid a repeat of the PS3 fiasco. Previous presentations from them have been nicer for those with a grounding in programming and/or electronics but even those with a passing interest have tended to gain an awful lot from them. The console hacking talk itself is scheduled for the 27th of December at 20:30 local time in Saal 2, as it is held in Hamburg the local time time is Berlin time so GMT+1 which should be nicer for our American members than a lot of previous conferences. As ever various members will be chatting and discussing the happenings on IRC during the event so you are welcome to join us there.
Beyond that hacking conferences are some great places to learn about the latest and greatest hacking techniques, be introduced to techniques you have wanted to learn but never found a great explanation of and generally hear some interesting talks by some interesting people, the channels of the videos linked in the paragraph above feature many such videos from hacker conferences. C3 has long had some of the best live streaming of conferences anywhere, this year is set to be better than ever and many of the people responsible will mirror videos and upload them to the likes of youtube in very short order for those that missed them.
For those unfamiliar with the C3 setup it is quite simple, being a German club and hosted in Germany some German terms get used but it is all good. Though it is a German conference no small number of talks are held in English, if you are looking at the schedule then it will have a bracketed (En) in the description for talks in English.
The schedule is also known as the farhplan and you can view this year's on the following link

Talks are then held in various rooms or Saal as they get called.
Again streams can be viewed in various formats on various devices.
https://events.ccc.de/congress/2013/wiki/Streams has links if you prefer to watch in something like VLC or even some android devices.
http://streaming.media.ccc.de/ if you just want a simple web link.
Talk a look through the talks list, are that any that catch your eye? A quick straw poll of the staff says there looks to be enough to occupy our downtime up until the US hacker conference season spins up.
