Some days before congress we asked you to create videos of your home hackerspace/community. Those videos were then shown during longer breaks on stage and sometimes also appeared in the streams. A big THANK YOU for all the people who did a great job on such a short notice to show us their world and how diverse the hackerspace movement really is.

Because the videos we’re shown randomly and without prior notification, there is a big chance, that you did not see all the awesome Videos, that have been created for project C.H.A.O.S. That’s the reason, why we want to showcase them here. For privacy …

TL;DR: Ask everyone who you can see in your lens for their permission before taking a picture or video! If someone asks you to delete a photo they might be in, or put away your camera, please do so!

Each congress is a huge social event, a great time many people want to remember and share with their friends. Thanks to smartphones and social media, photography in public places increases year after year.

Some of you in attendance may be very accustomed to environments where taking pictures and videos in public areas is common place. The 30C3 is not one of those places. For a variety of reasons, …

There was a time when we put all user-generated community-driven crowdsourced events under the label “workshops”. We said that a workshop need not be an event with hands-on and making, it’s just something that happens at a special time and place, outside of the big halls.

For the 30c3, we’ve added 3 new REALLY BIG rooms (Hall D-F) in addition to the halls we used last year (Hall 13-14) just for your events. We also chose a more appropriate name for everything that is organized by you: “Self-organized Sessions“.

It doesn’t matter whether you want to give an introduction into your favorite …

Remember when we met in Berlin at the bcc? The 25C3 was when we first stuck those pesky signs on the door that read “Sold out, we’re sorry”. The building was already incredibly packed and we couldn’t let anyone in anymore. This inspired the concept of “congress everywhere” which debuted at the 26C3. The theme of that congress was “Here be Dragons”, so the idea to expand the fun of the congress beyond the bcc was called “Dragons everywhere”.

But what was this notion of “congress everywhere”? …

“You can create art and beauty on a computer.” The quote has been derived from Steven Levy’s famous hacker ethic in his book »Hackers: Heroes of the Computer Revolution« – published in 1984, the debut year of the Chaos Communication Congress at Bürgerhaus Eidelstedt in the Freie und Hansestadt Hamburg.

30 years later »Art & Beauty« (»Kunst und Schönheit«) – its ironic twist entirely unfolding in German language – is one of five content tracks in the conference program. You can’t overlook it in the Fahrplan –  the purple colour coding is as weird as the naming is misleading.

The particular …

TL;DR: Please get to the CCH by 25th/26th with your assembly setup if possible

Beat the crowds and start building your assembly on the 25th! (Day -1). It makes loading so much easier for all of us and gives you time to make sure you have everything you need. Why get stuck in traffic around and inside the building? If you arrive early enough on the 25th, you may even be able to drive right into the unloading hall!

If you’re unloading a vehicle with equipment or other stuff you plan to use at the 30C3, put <a …

Die Funkamateure im Umfeld des Chaos Computer Clubs, genannt Chaoswelle (Assembly) bringen ein ganz besonderes Stück Hardware mit: einen Radom. Den wollen wir auf dem Dach aufbauen – was da drunter versteckt wird, verraten wir nicht!

Aufgebaut ist das Radom etwa vier Meter im Durchmesser, und es gehörte früher den USA und stand im Bayrischen Wald, um dort gewisse “feindliche Nachbarländer” abzuhören. Zwischenzeitlich gehört es einer Sternwarte, die es uns gerne zur Verfügung stellt.

Dear Congress Visitors!

You’re tired of running around the Congress on the Schnitzeljagd (sounds like it’s fun!) or didn’t get a place? You’re like knocking your head on problems? Then we might offer something interesting for you!

Grab a few friends and join our capture the flag competition. These so called CTFs are hacking competitions in which participants solve various challenges – all based around gaining access to remote machines by exploiting vulnerable binaries, solving mathematical problems and completing various other tasks. This CTF will be run in “Jeopardy” style, i.e. challenges …

Die Kohlenstoffeinheiten, die den Congress erst möglich machen, werden gemeinhin auch Engel genannt. Sie kümmern sich um alles, angefangen vom Aufbau, Audio-Aufzeichnungen der Vorträge über die Einlasskontrolle, Pressebetreuung, Simultanübersetzung bis hin zum Abbau.

Aber was ist das Besondere daran ein Engel zu sein? Eine Frage, die man jedes Jahr neu beantworten muss. Denn der Congress lebt von seinen Besuchern und den freiwilligen Helfern, die ihn jedes Jahr neu erschaffen und mit ihrer Kreativität jedes Jahr anderes werden lassen als die Jahre zuvor. Willst Du, dass Deine Kreativität und …

For the 30C3 we have designed a scavenger hunt for hackers and geeks. You will be challenged with puzzles and tasks including writing code, printing 3D objects, solving riddles and much, much more… The hunt will take place on the second day of the congress (28th of December) from 2pm to around 8pm and is made for about 10 teams competing with each other. A team should consist of 3 to 6 members. All you need is a computer, a twitter and email account and a blog of your choice (soup, tumblr, etc.) for documentation purposes.

If you like challenging riddles and games, write to info (at) …
