34C3: tuwat (2017)

#tuwat, make congress accessible for all creatures


Are you suffering from post-congress withdrawal? Do you want to watch congress talks but keep scrolling media.ccc.de, thinking “meh”?
#tuwat, watch talks and be a productive part of congress at the same time!
Our subtitling efforts continue between congresses, join us on c3subtitles.de and in our IRC channel #subtitles on hackint.org!

What’s there to do?

Creating subtitles comprises two phases: writing the transcript and mapping it to the video.
For the first phase you will need to correct an autogenerated transcript. If you would rather like to write a transcript from scratch, you are of …

Kommt vorbei – der 34C3 baut ab


34C3 is not over yet! We are tearing down, as every year, and would like to invite you to help the event. If you are still up for some community work then drop by.

Teardown will happen until January 5th. and we can use help daily from about 11:00.

On January 4th starting at 09:00 we could use some extra help – specifically people who are physically fit – to load large amounts of flightcases and other equipment.

You can find up-to-date information about this on Twitter under @c3logistics or by phone on 0341-39294864

Rück-Bauwat! (Teardown)


Dear life forms participating in Congress,

tomorrow, 34c3 will sadly come to an end and teardown awaits. For that, we need your help.

We ask all assemblies to dismantle their installation after the Closing Event at 18:15 on December 30th. After packing your stuff, please stack your tables and chairs correctly sorted and clean of stickers. Please do not remove said chairs and tables from your assembly place, but stack them at the very location.

But tearing down the assemblies is not everything, we are happy for every helping hand. We are creating teardown shifts in the Engelsystem and ask you …

Assemblies am 27.12.


Dear Assemblies,

please be aware that you need your congress wristband to enter the premises from today on. Furthermore we need you to send us your car’s number plate if you need back access to unload them, please send them as an email to 34c3@c3loc.de. Otherwise you won’t be able to enter the lot with a car. Please do keep in mind that you must spend at most 45 minutes in the lot. Afterwards parking will cost 64€.

Translations at 34C3


TL;DR: Just like in previous years, a team of translation angels will be on hand to whisper simultaneous interpretations of all talks at 34C3 in your ear, starting right on day one. All German talks will be translated to English, and all English talks to German. There is a second translation stream in all four locations that we will use for various target languages – catch the heralds’ announcements for details. To listen to the translations, you will need a device with either a web browser, a generic audio stream player (such as VLC), or a Mumble client (“work in progress”). We cannot provide …

Assembly deliveries


Dear Assemblies,

the Congress is now right around the corner and you’re asking yourself how to best deliver your assembly equipment. Bringing things by car will be especially easy this year, as you can drive them right up to the gates of Hall 2.

This years procedure will look like this:

  • Use c3nav to find out where your assembly is located (search for the name and then click on “Details”) [currently c3nav is still WIP. If you can’t find your assembly right now, come back later. In urgent cases ask the assembly team.]
  • Look for the gate in hall 2 closest to your assembly.
  • Use the entrance “Tor 1 …

The 34C3 Awareness Team


Not all of the 15.000 visitors at 34C3 will have the same needs and stance.

Thoughtfulness and respecting individual boundaries should be taken for granted. But within such a large crowd, individual boundaries can be crossed – sometimes even without the intention to do so.

This is why – just like in past years – there will be an awareness team at 34C3. The awareness team will work closely together with the team “Safety and Security” and the “Chaos Emergency Response Team” (CERT).

  • Safety & Security: DECT 110
  • CERT: DECT 112
  • Awarenessteam: DECT 113

If you do not have a DECT phone, any angel …

tu wat – GSM and UMTS will be ready


Good news everybody: There will be GSM at 34c3! We even have 5000 plain
white SIM cards available which will be distributed by the POC again,
for a small fee of 2€ per card. SIM cards from previous events will work
as well.

The GSM network will work on 1800 MHz (DCS-1800), so it should work with
all European and quad band phones.

Additionally to the GSM network, there will also be a UMTS (3G) network
on 850 MHz (Band 5). These frequencies are very common in US phones and
should also work a lot of modern high-end LTE (4G) phones. If you want
to be sure, please look it up for your specific …

Phone infrastructure at 34C3

Phone infrastructure at 34C3


Needless to say, we will provide to you a phone infrastructure at Leipzig. Please do not forget to bring your DECT and mobile phone with you (and the correct charger, maybe even a headset if you have one). The congress is hosted in Leipzig for the first time, really the biggest congress location ever and maybe we have some unknown constraints. We are prepared for this big event with up to four system components (in Hamburg we had one) and up to 60 antennas (in Hamburg we had 45). We try our best to provide a comprehensive DECT network, but can’t promise because of the unknown building. If you …

Call for Interpreters: translate 34C3!


If you are multilingual and fluent in German and English, please consider joining the translation team.

We interpret ALL talks in the four main halls live. German talks are interpreted into English, and vice versa. Our work is transmitted live in the lecture halls, streamed to the Internet, and recordings are published on CCC sites and YouTube. Also, like last year, we will be having a second translation channel in the two largest halls (Saal A & B) transmitted the same way.

That is a lot of stuff to translate, and for that we need YOU. At Saal A & B, you have the chance to contribute …

Self-organized Sessions forms are opening on WED DEC 20th, 9 PM CET


Many of you have been patiently asking for this: Finally we’ll have the wiki forms ready for you to enter your self-organized sessions on Wednesday, 9 PM CET. That way you’ll wide up the topics and the program of 34C3 and contribute your bit to a divers and versatile congress!

With the move to Leipzig come some changes: The CCL has fewer rooms than the CCH so we needed something new. Thus we created the concept of “clusters” with stages. This year there are a number of clusters, each one committed to one or two topics. Each cluster has at least one stage, some have more. They often have their …

tuwat – Assemblies at 34C3


Dear Assemblies,

many of you are already preparing for the 34th Chaos Communication Congress.
You are planing, crafting and packing. In order to achieve a stress-free congress build-up at our new venue, we like to inform you about this year’s specifics:

tudat: Rules of the Game for Assemblies

Noise and Sound

Hall 2 will contain areas for assemblies, Kidspace, bar, catering and other installations amongst which some thousand chaotic nerds will mingle on 15.000 square meters.
The remaining 5.000 square meters in Hall 2 are seperated from assembly space via movable partition walls and will …

Autism at 34C3

Autism at 34C3


TL;DR: If you need a quiet place or support, you can reach out to Sam, see below for contact details.

The Chaos Communication Congress is a tolerant and welcoming space for lifeforms of all kinds. In accordance with our hacker ethics we do not draw any difference based on ethnicity, gender, degrees or else. In short: Congress is colorful.

It is not always easy to accommodate the needs and wishes of every single group or individual. But that doesn’t mean we’re not trying to do our best. We listen to your criticism and recommendations and try to get a little better every year, expanding our …



Dear Angels,

Below are some important details for the 34C3 Buildup.
Please read them carefully.

Buildup Angel

Similar to the 34C3 it self, buildup and teardown only work thanks to the heroic effort and participation of countless volunteers. Warm thanks to everyone who helps to bring Congress to Leipzig, we very much appreciate every bit of help.
Even though buildup nominally starts on the 16.12. true parallelization does not take hold until the 18.12.. Before that we need some time to boot and warm up ourselves. For this reason our suggestion (especially to non-local volunteers) is to have a …

Warm and all night: Tram.

For the first time in the history of CCC, Congress will not be held in a downtown area but a little further out. We had to relocate to Messe

Leipzig this year. This comes with a number of challenges. Moving conveniently between downtown and the 34C3 location is one of these challenges that we put a lot of thought and energy in. Hotel capacities at the fair grounds are limited, …

A galactic Congress welcomes all lifeforms

A galactic Congress welcomes all lifeforms


Anyone who ever experienced the distinct feeling of „wow!“ on the first Congress knows: There’s an outside world and then there’s Congress. Even though the event copes with challenges that come with growth, we think we’ve built a space that promotes tolerance, curiosity, fun, open-minded communication, friendliness and cooperation. Unlike traditional conferences, where visitors receive full service for paying an entrance fee, CCC events are run by volunteers. The whole event is organized by people who buy their own tickets and spend their holidays to make it happen. Visiting 34c3 means to …

It’s that time again – the Chaos Communication Congress is coming! This year the congress moves to Leipzig and many new people will visit the Congress for the first time, perhaps even you? If so then we want to welcome you and help you get off to a good start.

Who are the Chaos Mentors for?

You’ve always wanted to go to the Chaos Communication Congress and are interested in topics such as privacy, security, hardware hacking or network policies, but have so far had little to no connection to the community? You visit the congress, but you have the impression that you are not one of these …

We’ll have a huge chunk of an exhibition hall for the Assemblies with nearly three times the space as there was in Hamburg. To transform a faceless and boring exhibition hall into a cosy, hacky, welcoming and inspirational place, we need you!

Over the last years the concept of Assemblies was constantly evolving and changing. With our move to Leipzig, there are new challenges and opportunities. In this huge space, Assemblies, people and groups will gather around different subjects, interests and competences. These will be represented by “Chaos Competence …
