The CCC is the Chaos Communication Congress where yearly, between Xmas and the new year, hackers get together in Germany to discuss computer security, politic and everything and anything in between.

Videos are recorded live, dubbed, subtitled and shared on the media server, freely available to all.

Maybe you should add some information for people who dont know what ccc is.

Also linking 39c9 in general instead of specific videos is maybe not best idea if you just want to pint out the privacy related videos.
