23C3: Who can you trust? (2006)

23C3 audio and video recordings available


We finally made it. Again, way too much time passed to finish off the complete set of recordings due to a technical problem on day one which forced us to re-capture and re-edit a quarter of the recordings. It always good to have backups.

But now we can provide you with the complete set of recordings in both audio-only and the complete video version. All videos are sized 640×480 pixels and are superbly encoded featuring very low bitrates and an unusually good video quality at the same time. All files can be played back on the iPod. Thanks to the 23C3 video crew of FEM Ilmenau and CCC Ulm for …

Looking for cool quotes, help wanted


We are currently producing a video documentary of the recent 23C3 event. We have tons of nice footage and interesting interviews, but we want more. So we are looking for cool quotes by speakers in the lectures being held at 23C3 and we want you to spot them for us as it is an enormous task for a few people but probably feasible for a huge crowd doing it in parallel.

So take a look at our preliminary video recordings (they are almost complete, just some talks of the first day are missing as they have to be re-captured from tape). We are looking for insightful statements that reflect our …

23C3 Lecture Videos forthcoming


While some 23C3 lecture recordings have already been leaked to the net, the official high-quality recordings are still in preparation (but making good progress). We do not encourage redistribution of the leaked videos as they lack proper license information, titles and correct meta-data. Please note that all material is released under CC-NC-

The to-be-released files come in MPEG-4 H.264 640×480 format and will be pretty small. The files are iPod-compatible and will hopefully be released as a podcast soon after.

23C3 Press reviews and other articles


Please contribute to our press review section and please also add longer blog posts about 23C3 as we consider them to be “press” as well. So far the list is lacking a lot of non-German reports. Thanks for your help.

23C3 is over.


We couldn’t be happier with how everything went. This have been four days of exciting activity and creativity, discussion and communication. Thanks to everybody for coming, sharing ideas and just being great.

Please give us some feedback. We really love to know about everything you liked or that can be done better next time.
Also you can tell us your opinion about every talk you saw. Go to the talk’s page in the Fahrplan and click at the green link.

We want your pics

IP Lecture Streaming


If you want to receive the 23C3 lectures live via TCP/IP, consult the Streams page in the 23C3 Wiki. It always reflects the current status and provides the necessary streaming URLs.

Getting faster to the congress


We are, as usual, expecting a really big run for entry tickets on the morning of the 27th – you had to wait about an hour last year. However, the ticket counter will open already on 26th in the evening. It is scheduled to open at 20:00, probably earlier. So if you are already in Berlin, please buy your ticket on the 26th in the evening. It will be a lot easier and faster for you and us – and will save you a lot of time standing in some cold ugly weather condition.

Everything else right now seems to work out quite smooth, no bigger fuckups, internet connectivity is already running. Oh, and just …

Hacker Ethics Hotline


Sometimes, while hacking, suddenly questions pop up:

What happens if I 0wn that box now?
Is it ethically justifiable to do this or that?
How much stress will happen if things go wrong?
What is the most efficient way to handle an interesting piece of information?
The Hacker Ethics Hotline offers fast and anonymous counseling on this and related topics.
Simply dial 1042 on the DECT phone next to you and make an appointment (real life, chat or phone). The Hacker Ethics Hotline is run by FX of Phenoelit, Ron, 46halbe and Frank Rieger.

Bring your DECT.


[basic info]
The POC will provide the telephone system (Alcatel OmniPCX 4400) combined with an asterisk system for VoIP which is fully integrated into the PBX System.

Additionally the POC will also provide cable bound phones
which will be connected via the structured cabling system of the BCC.

Everybody can bring his own DECT/GAP compatible phone, which will be registered into the system.

[payoff] “a cellphone is so much more useful – why bring a DECT phone, too?”

you should bring a DECT phone for the following four reasons:

  1. you can talk to other DECT phone users locally at the congress for …

Prepare for Impact


Today was the “kickoff” day at the bcc, our very first day getting everything set up for the congress in the building. As every year, it was mostly a delivery day. Shirts, the proceedings and a lot of other stuff we need for the organization arrived – all the stuff we need quite early in our congress setup.


Most of the hardware used for the congress network is already in the building, huge stacks full of switches and routers were delivered today. Quite a lot of …

Lightning Talks


Lightning Talks give you up to ten short talks each day – between 4pm and 5pm.
Each talk is limited to five minutes.

Usually the topic is some cool program
or project – but it can also be a good rant.
So this year’s motto is “The good *and* the bad”.

You can still add your own praise or rant
by adding it to the page within the wiki.
Enter the title, language (DE/EN),
your name, contact address, and a short description.

But whatever the topic – dive right in, and make it count!
One “word” of introduction should suffice, and then
give us as many info as you can within four minutes;
when your …

Searching for volunteers: Heralds at 23C3


The congress fahrplan is nearing completion, and we’re starting to plan the details. One important part of this is finding Heralds: volunteers who for a couple of hours are willing to be the main spokesperson in a conference room, who announce the individual sessions, and help out when something goes wrong.

Photo by smallcaps.

This year we would like to have a Herald for every single talk, not just the big ones in Saal 1. That’s quite an ambitious goal (our Herald schedule is comprised of 44 shifts), …

Lectures via DVB-T


If you have a DVB-T receiver for your computer don’t forget to bring it to 23C3 as we are about to broadcast locally all for lecture rooms via DVB-T this time. This is an experiment and is considered to be an additional way of broadcasting the lectures (we try to provide public TVs and IP Streaming).

We still have problems getting enough TV Sets for 23C3. If you have the option to borrow some sets or know of a source where we could lend 10 to 15 sets, [please let us know][3].

Fahrplan 0.3


We just published Fahrplan version 0.3. There are some minor changes due to special wishes of speakers. But the main difference are the workshops which are now visible in the Fahrplan. Have a look.

The Smoking Situation revisited


Nobody likes bans and regulations. Some people smoke at the Congress, some don’t. Almost all people hate the smell of cold smoke everywhere after four days at the Congress. So here we are again, asking you to understand and trying to make things acceptable for dislikers of bans and regulations, like ourselves. Here’s what we wrote last year:

Non Smoking Ashtray Quite an issue last year. Smoking situation was so bad that even heavy smokers complained about the bad air. Of course, smoking is forbidden in the art&beauty-area, the lecture halls and in the Hackcenter, as it was last year.

But for the rings …

23C3 On TV in the Land of the Rising Sun


Blog TV in Japan shows an Interview with German mobile entrepreneur Jan Michael Hess. After some minutes of talking about mobile economy, they mention an event that captures the interest of the Japanese hosts: A hacker conference in Europe. They even learn something important: “Hackers are good people”. Watch it yourself (the interview is partly in English):

Blog TV has a page (in Japanese) that offers additional information. A nice piece that shows people are actually interested in the stuff we do in corners of the world where you wouldn’t expect it. Domo arigato!

The content of this blog posting is true.


Of course, the title of this blog posting is wrong.

This is the 23rd Chaos Communication Congress. For some of you, this number might ring a bell, in a Pavlovian sense that is. Apart from the fact that a 1998 film telling a story somehow connected to the CCC and the Cold War era hacker scene had the very title 23, this number is also related to Discordianism, a modern, chaos-based religion founded in either 1958 or 1959. It has been described as both an elaborate joke disguised as a religion, and as a religion disguised as an elaborate joke. Some of its followers make the claim that it is “a …

Cold, hard facts on voting computers


We all need to have people after whom we can model our lives. We are not sure everybody knows Rop Gonggrijp but if you don’t you should. He is the one who will take a look at some cold, hard facts on voting computers on day 1 at 8:30 PM.

Amsterdam just dismissed electronic voting computers for the elections. Rop will talk about his fight against this computers and for (not only) Dutch voters to verify their votes. You will learn why there are many reasons to not placing the whole system of hand counts in jeopardy: simplicity, transparency, and plenty of witnesses who can understand the voting …

Do you want your own room?


As we told you at the Congress Website:

We encourage you to come up with good ideas, interesting projects and general feedback at any time.

But to do interesting projects you need space and time to discuss, to present some ideas and to work in a smaller group of people on a hands-on basis. The place to do that is the workshop room, where some tables and 23 chairs, a video projector and up to two hours time give you the opportunity to be part of the congress program.

There already are some very cool workshops:

It’s there…


The Fahrplan is out. Have a look.

The conference will present about 120 lectures ranging from an report about the RFID Hacking efforts of the CCC in the last year, to a discussion of State Authorities Access to Sensible Information, to an overview about Culture Jamming & Discordianism. Voting Computer will be a topic too, of course.

If you miss something in the schedule or just want to tell something, you have still the opportunity to do so. Present and discuss your own topics in the Workshop Room or give a Lightning Talk. Just reserve some time in the Wiki.

Fahrplan is close to release


Good news everyone. The official 23C3 schedule is mostly done. It will be released with the week. Stay tuned.

Stay tuned


We have had our share of problems getting out to you and the 23C3 website is in need of an significant update. But we are working on it.

23C3 is on track and welcomes everybody at the end of the year. We try to make it enjoyable and interesting as you expect it to be. The content is mostly fixed and we will try to get the schedule done as soon as possible. We might release a preview list of lectures before putting out the fully timed schedule.

Give us some pressure by putting up questions for the stuff you miss the most so that we can make sure we provide everything you need to know now. Feel …

With a little help from our friends


Executive summary: We are a bit in trouble and we need money to secure our future projects and we are looking for people and organizations to support us. If you think you can help, please read the rest of this article to understand what we are looking for. Thanks.

If you are following this blog, chances are high you are a following our activities for a while, probably even for a long time. In a few weeks, CCC will turn 25 years (!) and next Congress at the end of the year will be the 23rd reiteration. This is a long time and we have come a long way. But since the beginning a lot of things have …

Good ideas deserve it to be popular, which is why we adopted a cool idea from reboot.dk:

While we are still finetuning our Call for Papers for 23C3, which will be out soon, we ask for your suggestions and ideas, as already mentioned some days ago in this blog. Who do you want to see holding a lecture at 23C3? Which topics are the most important ones, which do you want to have covered this year?

We take your ideas and suggestions quite serious, so this is a cool advantage to shape the congress just like you want it to have – so head over to our Public Wiki, and either add your count to another …
