The Event

The 28th Chaos Communication Congress (28C3) is a annual four-day conference on technology, society and utopia. The Congress offers lectures and workshops on a multitude of topics including (but not limited to) information technology and generally a critical-creative attitude towards technology and the discussion about the effects of technological advances on society.

For 28 years, the congress is organized by the community and appreciates all kinds of participation. You are encouraged to contribute by volunteering, setting up and attending hands-on events or presenting your own projects to fellow hackers.

Some basic survival guidelines might come in handy for everything not answered in our 28C3 FAQ. Like last year we search for helpers in our distributed congress program, no nerd left behind. Updated information are covered by the CCC Events Blog or via Twitter (@CCC).

As this website is part of a wiki you can contribute information, too. Login or register an account and go ahead. Refer to this help page for information about using a MediaWiki.

As practised with 26C3 and 27C3 we want you to come together. no nerd left behind: Allow those unable to attend the Congress in Berlin to celebrate their own Hack Center Experience, watch the streams, participate via twitter or chats, drink Tschunk, cook and have a good time.
