Timetables for 39C3, hot off the press: The Fahrplan is out

Tue, 02 Dec 2025 08:00:00 +0200

After the halfnarp is before the schedule. Thanks to you, and thanks to the many helping hands of the content teams, we can now present to you the first version of the 39C3 Fahrplan!

The official stage programme at the 39th Chaos Communication Congress starts on 27 December, 10:30 with the opening ceremony and shines with a total of 165 talks. These have been lovingly sorted and curated for you into seven topical tracks. There is definitely something for everyone!

To those of you who now have counted manually or even found the gaps in the schedule: That’s right, because we have a few surprise talks that we can only reveal shortly before 39C3. This Fahrplan is version Alpha-0.2. Traditionally there will be minor changes up to and even during Congress. So it’s worth checking back from time to time to see what the content team has prepared for you.

Are you ready to haaaaaaaaaaalfnarp?

Sun, 17 Nov 2024 00:00:00 +0000

In what has become a cherished tradition, the 38C3 content teams want to take the pulse of our community and offer you a deal that’s really hard to refuse: You get an early look at what our teams think are the best talks and presentations that will make for a well-rounded 38C3 Fahrplan, and in return you allow us to identify clusters of talks that we should avoid scheduling at the same time.

All you have to do is 1) click on all the talks you want to see, 2) hit submit and 3) skip step three! We’ll take it from there and let the number crunchers generate a collision map that will magically make equally charged talks repel each other!

You can marvel at the miracle machine fuelled by your submissions in this time-lapse video:

/media/fullnarp_35C3.mp4

As a bonus, this collision map will be used back at halfnarp to help you find other talks that the community has deemed related to the ones you found interesting. Later it will even feed the “related videos” algorithm at media.ccc.de.

So, what’s not to like? Head over to halfnarp right now and hit submit!

I remember doing the halfnarp!

Mon, 04 Dec 2023 00:00:00 +0000

The 37C3 content teams have been sorting, discussing, ranking, shuffling, haggling and hustling for more stage-hours and are proud to present you a preliminary look at the first 104 confirmed of around 125 accepted lectures and performances at this year’s Congress.

It’s been an exhausting process with 600 submissions in six tracks and a handful of invited presentations meaning that some tracks had to chose 1 lecture from 10 others not making it into the final Fahrplan. If you are among the ones getting a sad email, rest assured that you are in excellent company and encourage you to reach out to our teams managing the self organised sessions and workshops or invite yourself to one of the many Assemblies and share your knowledge there.

Still, we are really thrilled about the quality of this year’s submissions and want to allow everyone a first glimps on our Fahrplan in exchange for you helping us out with the precise schedule which is due to be planned next weekend: As seen in previous years and years, we also need your support for 37C3 telling us which lectures you want to attend. By mapping your anonymous list of lectures to these of your peers, we can create a conflict map as seen in the video below, that helps us reduce the amount of conflicts between multiple lectures you may want to attend.

So hop over to the halfnarp now and let the community magic do its work!

Camp 2023 – Fahrplan 0.9 release

Thu, 03 Aug 2023 00:00:00 +0000

After many hours of reviews and haggling over the proposed entries, the content teams are proud to present you version 0.9 of the Fahrplan.

Find the schedule on pretalx

We and our awesome speakers and artists present you about 150 Talks, over 60 workshops and almost 50 performance gigs on 10 stages and areas.

For the Chaos Communication Camp 2023, we took a new approach to create this programme, with stages being run by multiple villages. We had to learn a lot while running this approach, so this first schedule comes pretty late. We would like to apologise for any inconvenience this has caused for our speakers.

We received more than 400 proposals overall. We want to thank everyone who submitted an entry. Feel encouraged to host a self-organised session if you did not get accepted. You awesome people submitted way more than we could accept. Deciding what we would have to reject was not easy.

Meet the 36C3 track team “Resilience and Sustainability”

Tue, 03 Dec 2019 23:23:36 +0000

We’re 36C3’s Resilience and Sustainability content team and want to show you just our bit of work that helped making this year’s Fahrplan as amazing as it has turned out.

Our team consists of hackers and scientists, tinkerers and PhDs and was formed for 34C3 when we felt that the conference was developing a blind spot between complete destruction of all the IT things and the fascinations for the resulting apocalypse. We wanted to give a stage to new and shiny useful technology for a better and more resilient world – with actual prototypes!

This year’s motto “resource exhaustion” added a perspective on sustainability to the track – even though the term is rather overloaded. There’s a plethora of conferences selling you on the most recent hypes about how machine learning, crypto currencies and the cloud will save the world, but we think that it is in the spirit of this community to question everything, think and focus on technology that will last for much longer – both physically and from a software engineering point of view. We found it fitting to see how the existing resources can be used and reused, who’s building resilient technologies that can help people in emergencies, oppressive regimes or off-grid situations, and – in a broader scope – how can we build the systems of the future not riddled by the problems of our generation.

Along the way, we hope we can make software developers think about the impact of their busy-looping JS, bad communication patterns and faulty software architecture – all of which are significantly contributing to climate change.

The concept of resilience itself – especially combined with sustainability – is rather interdisciplinary, part hacking and making, part science and politics. This puts us in competition with other track teams trying to catch the most interesting lectures for a given subject, but also allowed us to trade slots with those teams as well, once we were running out of our allotted time budget. ;)

Next year, we hope to collect the “haveyoursay” feedback much earlier so we can incorporate your feedback and follow your suggestions for valuable speakers and topics.

While we were quite pleased with the submissions we found once CfP kicked off, our curation process started way earlier: Reflecting on feedback we received after 35C3, we came together in IRC and RL, brainstormed about interesting projects we heard about in the past year, thought about relevant topics and identified speakers worth having.

Even then, the speakers we “invited” still had to go through our rigorous curation process. After all, our team received a total of 74 lecture submissions and had to narrow them down into only 15 hours (in 18 lectures) of 36C3 programme. We vetted each submitter, trying to make sense of their submission, read their papers, ask and answer questions and spend the remaining time meeting and coordinating with all the other track teams, before finally writing this blog post! If we add up all the time spent preparing our 18 lecture foot steps in the Fahrplan, we’re looking at one or two weeks full time work for each of us.

In the end we’re quite proud of the topics we could cover this year. Of course, we’re still not short of topics to cover next year :-) It’s time for more critical reflection of wastefulness within the computer nerd scene and how we can minimise the environmental impact of our C3s and Camps in the years to come.

36c3: Have your say

Fri, 20 Sep 2019 20:28:32 +0000

We would like to ask you, again.

The survey has been closed. Thanks for over 2000 submission!

You will be as surprised as we are: A new Chaos Communication Congress and its Call for Participation are coming up really soon now. And as we still wipe the Camp’s dust from our sleeves, we noticed that we might ask you for support.

Building a Congress Fahrplan requires working through a lot of submissions in our frab from people responding to our Call for Participation. But our restless curation teams will be also busy approaching potential speakers for topics not yet covered. However, from time to time, we were missing developments worth covering.

On the other hand, over the last years, we managed to tap into our community’s wisdom time and again to make our Fahrplans even better, you helped us with avoiding scheduling conflicts and with your preferences regarding our lecture grid. So naturally, it’s only fair to ask you again to help us out and use our tiny feedback tool you can find here https://content.events.ccc.de/haveyoursay to submit your ideas on what we could try to cover at 36C3 to make the next Congress a better experience for everyone!

Thank you!

(And please, refrain from any blockchain jokes.)

Fahrplan nach Euren Wünschen: Let’s do the halfnarp – agaaaaain!

Thu, 22 Nov 2018 18:31:21 +0000

Tl;dr: Please read the FAQ and do the halfnarp!

It’s that time of the year again: We’re going to gather in Leipzig at the Chaos Communication Congress with our fellow mad hatters and get lectured. But before we can have the time of our lives, we need you, you, you to make the Fahrplan as frictionless as possible – we have to shuffle around a record-breaking number of around 160 lectures.

Without further ado, we present the 35C3 halfnarp and would kindly ask you to lose yourself in the options, then mark and submit the lectures you plan to attend. We’ll take your data into account when scheduling lectures and later provide a recommendation web depending on the correlations we find. Our main goal is to make sure that certain most-clicked lectures will not happen at the same time. If you have any questions about the halfnarp, please see our FAQ.

And to make halfnarping even funnier for all those pausing Diablo Immortal on their phones, the new narpr(beta) feature allows for some easier interaction: it’s just a swipe to the left and then a swipe to the ri-i-i-i-ight – to mark your favourite things.

33C3 halfnarp: The talks that ‚work for us‘

Fri, 18 Nov 2016 16:56:07 +0000

The 33C3 content committee is proud to announce a lecture selection that ‚works for us‘. Our five hard-working 33C3 track teams have hand-picked a set of around 150 excellent lectures to be formed into the best four day, six track programme possible.

Having to select talks from an impressive lot of more than 500 submissions was a hard and sometimes frustrating task. But we have been amazed by the overwhelming interest in volunteering to present at 33C3. We’re thrilled to see that support and enthusiasm to contribute to this year’s event is as high as it ever been. Some speakers even refuse to accept a free ticket!

With this post, we want to do three things: Whet your appetite for our programme, ask for your help in putting together a collision-free schedule, and call for your workshops and self-organized sessions.

First, we present: The halfnarp https://halfnarp.events.ccc.de/.

In the halfnarp, you’ll find a list of all re-confirmed talks for each track (note: around 15 lectures are not yet re-confirmed, if you’re a speaker, please check your spam folder ;). You might notice that we offer a new track ‚Space‘, simply because we think all hackers should absolutely make space ‚work for them‘.

Second, we ask that you to help us put together a collision-free schedule that ‚works for you‘:

Select all lectures you would like to attend.
Press submit.
That’s it, there’s no step three. We’ll do the rest.

You can modify your choice at any time (don’t forget to press Submit again), or share it with your friends.

Third: The vast majority of submissions did not make it into the curated lecture programme. But that does not mean they wouldn’t be interesting to the crowd at 33C3. We invite you to present your ideas in lightning talks, gather in your assemblies or even get hands-on with a self organized session.

32nd Chaos Communication Congress: First version of the Fahrplan

Fri, 11 Dec 2015 00:25:13 +0000

Fasten your seatbelts! We have a Fahrplan here. Like in the last years, we used many hours to review all the submissions, communicated with potential speakers, let you do the Halfnarp to avoid collisions – and now we have it!

CC BY-SA 2.0 via flickr/Anna Jumped

We are happy to present version 0.9 (The Line Runners) of the

Fahrplan of the 32nd Chaos Communication Congress. Please note that this is not the final version. There are still some slots which in fact are not free but just not publicly seen yet and thus do not appear in the first version of the Fahrplan.

See you all in Hamburg!

P.S. Just like in last years we created a naming scheme for the Fahrplan. Have fun figuring it out! :}

Let’s have a camping Fahrplan!

Thu, 30 Jul 2015 12:14:29 +0000

There are only a few days left and we are late but finally it is here: the Fahrplan for the Chaos Communication Camp 2015. Due to circumstances we had some lags, but finally we made it!

Please note this safety advices by going through the Fahrplan to pick your sessions:

There is a new track: Failosophy. Read more about it in the Call for Papers.
Mind the gap between 12:30 and 16:00. This is siesta-time where no lecture will be held in the lecture-tents. We decided to do so as this timeframe will be incredibly hot and we do not want to constipate you in tents while the heats is rushing over the campsite. (However, there may be a self-organized session going on elsewhere)
There are still other gaps which will be filled magically within the next days till camp. Please come back on a regular basis to get the new talks.
There are Fahrplan Apps. Please move on to the Fahrplan-App wiki-page to see which are available.
For our pleasure and your curiosity we have a naming scheme for the releases of the Fahrplan. Maybe it is to easy, maybe to hard to figure it out. Let’s see what you can do with it.

Enough said – have a look at the first public available Fahrplan (Version 0.8 first and last and always) of the Chaos Communication Camp 2015.

We will meet each other in Mildenberg!

Fahrplan released!

Sat, 08 Dec 2012 19:35:21 +0000

You will find the Fahrplan version 0.1alpha at:

http://events.ccc.de/congress/2012/Fahrplan

Please also have a look at the wiki, as there might be alternative interfaces to the Fahrplan, such as mobile apps showing up. See also the <a href=“http://events.ccc.de/congress/2012/wiki/Calendar>Calendar to get an overview of the already planned <a href=“http://events.ccc.de/congress/2012/wiki/Workshops>Workshops. If you like to do your own workshop or some other event at the congress, you can add it there.

Crypto Talk at 27C3: Automatic Identification of Cryptographic Primitives in Software, Day1, 16:00, Saal 3

Mon, 27 Dec 2010 01:31:51 +0000

Many applications, including closed source applications like malware or DRM-enabled multimedia players (you might consider them as malware too) use cryptography. When analyzing these applications, a first step is the identification and localization of the cryptographic building blocks (cryptographic primitives, for example AES, DES, RSA…) in the applications. When these blocks have been localized, the input and output of the cryptographic primitives and the key management can be observed and the application can be analyzed further. Fortunately, many cryptographic algorithms use special constants or have a typical fingerprint and there are only a few different public implementations of the algorithm. This allows us to automate this first, Felix Gröbert will show us how:

Using dynamic binary instrumentation, we record instructions of a program during runtime and create a fine-grained trace. We implement a trace analysis tool, which also provides methods to reconstruct high-level information from a trace, for example control flow graphs or loops, to detect cryptographic algorithms and their parameters.

Trace driven/dynamic analysis has some advantages of static analysis:

Because the program is analyzed at runtime, it is immediately known which parts of the code are used at which time, so that they might be correlated with runtime decryption of the code or with network communication.
Inputs and outputs of the primitives as well as the keys are recorded, even if the originate from a remote server or botnet. This allows us to immediately distinguish between long term keys and session keys, if multiple executions of the same program can be recorded.
This is also highly interesting if private keys are included in an obfuscated binary, for example private RSA keys.
Dead or unused code is automatically excluded, so that one can proceed with the main parts of the code first.
If additional code is loaded from a server, it is included in the analysis. This would be hard to impossible using static analysis.

Of course, trace driven analysis has it disadvantages, for example if a malware needs to communicate with a command-and-control server, which has already been taken down or behaves differently on different systems or at different times.__

Personally, I am interested in this talk because it might make ease up the analysis of closed source applications using cryptography. Even if the application, the DRM scheme, or the cryptographic primitive has no special weaknesses or bugs, just he recording of every input and output of all cryptographic building blocks in the application might be sufficient to extract a DRM free version of DRM protected digital content. Please also note that even if an application uses only well analyzed cryptographic primitives as AES and RSA, it might still be insecure, if these primitives are used in the wrong way.

See the talk at Day 1, 16:00, Saal 3!

24 Hour Hardware Hacking Returns to 27c3

Thu, 16 Dec 2010 19:54:29 +0000

Hackers of all ages can (learn how to) make things at the Hardware Hacking Area of the 27c3!

The HHA is open to everyone and open the entire congress! Hackers of all ages and skill levels are welcome! Round-the-clock hands on workshops will be led by lots of experienced teachers like Mitch Altman, Jimmie P. Rodgers, fbz, Wim Vandeputte and…you!

Learn to solder, then help teach others! Make cool things with electronics, design and print 3D models on the Makerbot, break RFID, or give your own workshop on the projects you’ve been hacking on this year. Last year there was a Cantenna workshop, a Mikrocopter workshop, and a GSM workshop among many others.

Lots of kits for you to make will be available including Brain Machines, TV-B-Gones, Trippy RGB Waves, Mignonette Games, LEDcubes, LOL shields, Atari Punk Consoles…and there’s always room for yours!

To accommodate all this hardware hacking goodness, the HHA will be twice the size it was during the 26c3, but still conveniently located near the Hackcenter.

Even if you don’t have a ticket to Congress, you can stop by the HHA with a Night Pass good from Midnight to 6 AM. Night passes are only €5 and will be sold shortly before midnight each day of the 27c3.

Lightning Talks at the 27c3

Mon, 13 Dec 2010 19:04:15 +0000

Want four minutes on stage at the 27c3? You can have it! Registration is now open for the Lightning Talk sessions at the 27c3.

Taking place at 12:45 in Saal 3 on Days 2, 3 and 4, these fast paced sessions are perfect for pitching new software or hardware projects, exploits, creative pranks or strange ideas you need to share with the world.

Lightning talks are also good for getting publicity for your workshop at the 27c3, or for recruiting people to join in on things like a high calorie flash mob.

In order to maximize the available time, registrations will be granted to presenters who submit their graphics (i.e. slides, background picture, contact info, etc.) in advance. Exceptions will be made very selectively on a case-by-case basis. Register soon, as we anticipate the available slots will go quickly. (Proposals started coming in a few minutes after we put up a draft of the wiki page!)

Read the Lightning Talks article on the 27c3 wiki for more information!
