23rd Chaos Communication Congress
The Chaos Communication Congress is a "hacker" conference held annually in Berlin. The 23rd conference, like all of them, featured the most l33t hackers on the Internet who gave lectures about computer security, anonymity and other important subjects.
This years event's theme was "Who can you trust?".
Some of the interesting events who took place at 23C3:
 Detecting temperature through clock skew
Detecting temperature through clock skew by Steven J. Murdoch covered how temperature variations cause clock skew, a fact that can potentially be used to identify computers on the Internet in order to, for example, identify computers who are running location hidden Tor-services.
This event was covered in Wired Magazine..

 UnOfficial recordings
Unofficial recordings were made from the 23c3 live video streams during the event.
These are not official recordings and are in lower quality than the official recordings.
However, official recordings are not yet available for many of the lectures, so the unofficial videos may be of interest and value until official videos of all the events are made available.

 The 23c3 effects on the Internet
Many websites on the Internet seem to change or show very .. interesting .. content on some pages during the CCC events. These sites and pages are sometimes added to the "Hacks" page on the CCC website. Microsoft were very quick to remove the 23c3 logo from their Swedish website, while NASA had the 23c3 logo on a page on their weather site for quite some time.
The "Hacks" page also has (soon had?) a quite long list of links to /etc/passwd files on various websites... Other links on this page simply show pages with comments like "Hello, we've changed your password, your new admin password is mailed to you." and "You know, using a default password is bad"...
