rC3 Call for Subtitlers



Have you been hit by lockdown, you’re bored and you are craving for more chaos event feeling? Are you sitting at home and watching recorded Talks from rC3 and past Chaos events?
Bring a little bit of rC3 to your home and help with improving quality and accessibility of the CCC recordings! You can work on the subtitles from the comfort of your home, as long or as short as you like to!

How does this work?
The transcripts are generated automatically by speech recognition software and improved and corrected by you. Since talks contain lots of domain-specific terms and may have …

#rC3: Es war einmal kein Congress …

#rC3: Es war einmal kein Congress …


Once upon a time, the people of the nerds wanted to celebrate their annual festival. But the lands were struck by a pestilence, and it was dangerous to go out and meet other entities. The nerds lamented, for their festival was the highest holiday in their world. But they were all wise creatures, and since wise creatures do not let other creatures come to harm, the committee decided that the celebration would be canceled in the year of the plague.

But the people were strong and wise, and so they pondered. And someone suggested to create an enormous artificial island, which everyone could enter …

#rC3: Farewell

#rC3: Farewell


Sometime on the morning of Day 4, with the core orga-jitsi’s clock showing hour 48, we sat together for the handover. We pondered, mused, nerded, and asked what we could write to conclude. We settled on a well-known popculture-quote that the 2D-world-developers of this event used to describe their internal channel:

“In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.”
— Douglas Adams, The Restaurant at the End of the Universe

At the end of this event, after 96 hours of remote Chaos Experience, we ourselves cannot put …

Leere Talks? Relive!


Warum gibt es so viele leere Talks auf media.ccc.de? Wir ‘veröffentlichen’ automatisch Vorab-Mitschnitte aus den Live-Stream.

Wir haben zu diesen Themen viele interessierte Fragen bekommen und möchten Euch in diesem Beitrag kurz die Technik dahinter vorstellen.

Wie kam es zu Relive?

Früher™ hat es manchmal Wochen gedauert, bis Mitschnitte von Vorträgen online waren. In der Community gab es dann sogenannte „Streamdumps“, die man sich kompliziert zusammensuchen musste bzw. schwer auffindbar waren. Leider war auch die Qualität der Streamdumps meistens auch nicht gut oder wurden durch Dritte …

#rC3 Chaos Mentors


It’s that time again – the remote Chaos Experience (rC3) is coming! This time with a new format, with tickets for special virtual extra features – we are not sure how many people will visit this new event, nor what will exactly happen. In a way we are all first time visitors, aren’t we? Some people – you too? – may need some support to have a good start.

Who are the Chaos Mentors for?

Are you a member of an underrepresented group in the hacker community, and unsure if you will feel safe and comfortable at a digital distributed event? Or do you have specific needs that make it more difficult to …

#rC3: Takeoff

#rC3: Takeoff


This is the final blog post in the series while the last bits and bytes are falling into place: Getting Ready for the remote Chaos Experience.

Today we’ll give you some more information that you should definitely remember for rC3. Let’s get to work!

When and where does it start?

The digital gates of rC3 open tomorrow, 27.12.2020, at 12:20 pm with the intro in the stream rC1 and the ticket content at rc3.world .

Icanhaz Fahrplan!


Just in time for the event, the complete #rC3 timetable provides a unified overview of the “main program” and all community streams.

In addition to the virtual halls 1 and 2, appropriately titled “rc1” and “rc2”, the music program of the “rc3 Lounge” may of course not be missing.

In addition, 15 community streams contribute their independently curated program to the decentralized Remote Chaos Experience.

The independently organized and decentralized community streams provide the following “channels:”

  • c-base mainhall
  • Chaosstudio Hamburg
  • Chaostrawler
  • Chaos-West TV
  • Chaoszone TV
  • Franconian.net …

#rC3 Use more Jitsi!



The load test for our Jitsi infrastructure will take place soon.

We’ll kick off around 18:00 GMT+1 (that’s German local time) / or 17:00 UTC (still 18:00 German local time) at:


(If any error occurs to you, please send us an email to jitsi@rc3.world)

Open rooms, invite your friends and video-conference as much as you want.

We haven’t set a precise end for the load test, however the server will go offline briefly afterwards, but will then be available for you and your (chosen) family until the end of the event.

Stay distanced but socialize!

#rC3: Community Highlights

#rC3: Community Highlights


Hello and welcome as we approach the finish line!

Today we have some more important or practical information and a little retrospective of our blogpost series, concluded and garnished with a few thoughts on festivity, elective families and tradition.

First up, a correction to the weekend post: Close proximity conversations in the rC3-World do not run via Jitsi, but are part of the World-software and peer-to-peer. Jitsi is used for larger communication spaces in the rC3 World.
There is now a How-To-Play.

Those of you who carefully read during the weekend can rejoice again:
Today, Wednesday the …

#rC3: Technicians Are Informed!

#rC3: Technicians Are Informed!


Hello and Welcome to post No 6 on our chaotic journey to the remote Chaos Experience 2020.
Like the last few weekends, we bring you helpful, knowable and simple things(TM) that everyone can practically put in their pockets. The information noted here was all screwed up, made possible and gained from volunteers kept in a nerd-appropriate manner.

On that note, mate, unicorn and biscuits packed….

What the FAQ?

For rC3, even more information than usual needs to flow: Everything is new and the swarm knowledge you pass on year after year has to emerge. We have ground to make up in terms of …

Call for Interpreters: translate #rC3!


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

We want to interpret ALL talks in the two main channels and content from other channels too, live and in real time. Our work is transmitted live in the streams, and recordings are published on CCC sites and YouTube. For each event we have two channels for interpreted content. In the first, German talks are interpreted into English, and vice versa. A second translation channel translates into languages other than English or German – what we do there depends on …

#rC3: State of the Art

#rC3: State of the Art


Hello and welcome to post No 5 of the rC3 calendar!

Note: The second ticket batch is exhausted. Thank you so much for your overwhelming interest in this event! We hope you enjoy rC3.

This post has matured an extra day and comes out steaming hot! Sorry for keeping you hungry and waiting – we’re sure it’s worth it.

Today it’s all about culture, knowledge and their creators feat. the overall situation. We also have two surprise guests with a little something to share for those of you who would like to finally light it all on fire.

The Situation of Artists

As everyone has probably noticed by now, …

#rC3: How To aktive Teilnahme

#rC3: How To aktive Teilnahme


Welcome to the middle of the film warm-up blog!

Just like last weekend we bring you more information on how to participate in rC3 – because it all starts in a fortnight!

An appeal regarding the new ticket contingent: Please do _not_ click tickets for bots. Or your toaster, your fridges, or (insert any other IoT things here). Our capacity is limited and we would like to give priority to beings that pass the Turing Test. We will set up a small contingent for bots and, in the coming days, announce here how you can connect your toothbrush or remote-controlled telepresence robot.

But now to the …

#rc3: Call for Subtitles


Hey you, maybe you already know C3Subtitles from previous chaos events. We will also create subtitles for this years rC3! Especially people who are hard of hearing and people that don’t understand and speak the language of the talk perfectly will profit from them. But if that doesn’t apply to you, it doesn’t mean the subtitles can’t be beneficial to you: Just imagine your dad/flatmate/hamster is vacuuming at the very moment you wanted to enjoy a video…

If you want to participate in the subtitles team this year, just become an angel and join the team! We will create subtitles for the recorded …

#rC3: Stimmung DIY

#rC3: Stimmung DIY


Welcome to Part Three of this year’s getting in the mood blog posts, today with light hearted throwbacks and participation opportunities in the Tuesday edition.

What can you expect here today? Means and suggestions to get your homely cave, including yourself, in the mood for #rC3. It’s the story of trashy music, beloved merchandise and fine biscuit shapes, rounded off with two suggestions for flashing LED fun.

Grab a Mate and here we go …


Earlier this year during the DiVOC PTT three DIY 3D-printable cookie moulds were introduced by Benjamin-W. A rocket cookie is always a …

#rC3: Neues Ticket-Kontingent


On Saturday, 12.12.2020 at 14:00 (Berlin, CET, UTC +01:00) we’ll launch an additional ticket contingent.
If a third round will be available, is currently not sure.
Link to the ticket shop.

What the hack happened???

To be honest, we didn’t expect this number of people willing to participate in #rC3 and subsequently clicking tickets. Especially since in the beginning many said »not just another video conference« or »nawh, online ain’t mine«. But obviously, rC3 was interesting enough to clear out our initial ticket contingent.

Additional tickets

People worked hard in the past few days to …

rC3: virtueller Aufbau

rC3: virtueller Aufbau


Welcome back, this time we’re in “serious Saturday” mood, presenting the latest info on #rC3 participation.

We bring you this message while hard at work with the digital build-up. Oldtimers among you might wonder where the Wiki is, when the “Fahrplan” (schedule) will be available and what you can already prepare with and for your assembly.

The short answer is: yes.


The most pressing question probably is if and when more tickets will be available. Our volunteers are working hard trying to solve this problem, a big Thank You to them for that. We’ll get back to you as soon as we have …

rC3 Ticket Update


Please note: Streams are online available for everybody at media.ccc.de as always. You do NOT need a ticket to watch the streams. Tickets are only needed to access the rc3 world and participate outside of lectures.

Currently there are no tickets for rC3 available. We are really excited to see so many of you wanting to attend. As this event is volunteer-driven as always, resources are limited and this is all a big experiment.

Please be aware, that it’s not possible for us to scale the infrastructure infinitely. This has multiple reasons. The most important ones are:

  • Some infrastructure just …
rC3: Warm-Up

rC3: Warm-Up


Hi everyone,

in anticipation of rC3, we prepared a little treat in the form of an Advent calendar.

Every Tuesday and Saturday of the coming weeks, you will find posts here with chaotic entertainment: throwbacks and participation opportunities as well as helpful tips and tricks for a seamless entry into the upcoming remote Chaos Experience.

Let’s get to it…


This year, the bulk beverage delivery and bar operation is in bad shape. In order to have an adequate supply of stimulating cold drinks at home, we would like to draw your attention to a community project with tradition: Maps for the …

rC3: Tickets and Merch now available

rC3: Tickets and Merch now available


This year, CCC hosts the Remote Chaos Experience (rC3).

Ticket sales for rC3 now has started. T-Shirts, Hoodies and Zippers should be ordered until December 6th.

Primarily, rC3 will take place on screens and displays. Various initiatives, hackspaces and living rooms distributed worldwide will create a joint program of streamed talks, online workshops, art and culture. Together, we will experiment with various forms of networked togetherness.

Advance ticket sales

Thanks to the many angels investing their spare time, CCC events are known for their fair ticket prices. For rC3, we do not want to …

rC3: Design Release

rC3: Design Release


Hooray, we’re happy to announce the official rC3-Design & Styleguide!

Look through another window. You are not alone, just remote. It’s for our future.

This year, we do have a whole world to fill and build our »location« ourself. As an assembly you have the possibility to also contribute to our world. That’s why you find information about »maps« right next to the styleguide on howto.rc3.world. If you still want to register an assembly, you find all necessary information in our call for assemblies.

We are looking …

rC3: Call for Angels


The Remote Chaos Experience (rC3) is about to start and the preparations are running at full speed. Since everything is a little different this year due to the pandemic, we unfortunately cannot rely on a “same procedure as last year”, but have to enter this “Neuland” spontaneously, creatively and sometimes chaotically.

In order for us to master all the new challenges, we again need as many helpers as possible who are willing to make the event an unforgettable experience. That’s where you come in: Become an angel and help to make the Remote Chaos Experience a great event for everyone!

Please …

rC3: Call for Calls

rC3: Call for Calls


This year, the year-end event of the Chaos Computer Club will take place in the digital space. This poses new challenges for us as Phone Operation Center. But those who know us will already know that a “challenge accepted” is part of good manners.

For some time we have been working on a solution to enable a very large decentralized SIP & DECT telephone network. Our vision:

Network like at the congress – everywhere you want it.

Our plan is to have the SIP infrastructure in operation from the 15.11.2020 (0 o’clock). The DECT infrastructure is in productive operation since 10.11.2020. So …

rC3: Call for Participation


The Event

This year’s Remote Chaos Experience (rC3) brings together entities from all over the world in digital space. Between Christmas and New Year, we want to try out together what’s possible in cyberspace. We want to talk to each other, exchange ideas and learn from each other. We will talk about hardware, making, science, IT security, politics and whatever else.

Common CfP

The rC3 is a distributed event by us for us. Therefore, the different community stages in different cities play the decentral main role.
All community stages will have access to this CfP, so you submit your contribution …

rC3: Call for Assemblies


TL;DR: We are looking forward to your virtual rC3 assemblies! Please tell us about your ideas and requirements! Please register at signup.c3assemblies.de.

“You can’t do that in Hall 1”

Last year, we played copy-paste and tried to use the well-known paths. This year, everything is different. Physical distancing teaches us to strike out in new directions. So we meet in our natural habitat: the Internet.

The unexpected discovery of exciting projects is what makes the Congress feeling so unique every year. Blinking stuff everywhere. Things that want to be discovered. We want to take this feeling …

rC3 – remote Chaos Experience


This year, CCC hosts the Remote Chaos Experience (rC3) instead of an on-site event in Leipzig.
This endeavor requires creativity, joy of experimentation and active support.

A face-to-face event with 17,000 people will be neither responsible nor legally feasible this year. But after this tedious and painful 2020, we really deserve a nice finale!
This is why the rC3 – Remote Chaos Experience will be held.
As much as virtually possible, we want to convey the joy, content, togetherness and wonderful madness that make up a Chaos Communication Congress.

Hackers are used to remote work and online …
