GPN24: Update on financing, merchandise and call for participation

Wed, 08 Apr 2026 00:00:00 +0000

GPN24 is happening

Thanks to the fantastic support from the community, we are able to organise GPN again this year. We would like to extend our heartfelt thanks to everyone whose donations have made this event possible. You can find the current status of the fundraising campaign at donate.gulas.ch. We have surpassed the €80,000 target, so GPN24 is now confirmed. We will invest any further support in making GPN even better, in future events and in the GPN storage.

All places for the event are already taken through registrations. On the day, we will still be offering a limited number of free day passes to visitors from the Karlsruhe area.

We will provide updates on the availability of day passes during the event at gulas.ch and on the Fediverse at @ampel@gulas.ch.

Order merch until the 29th of April – no sale at the event

Until April 29th, you still have the chance to order exclusive merchandise. For the first time, we are also sending out (limited) merchandise by post from the Gulasch headquarters, so you don’t necessarily have to collect your order at GPN24.

There will no longer be any on-the-spot sales at the event; this year, merchandise can only be purchased via binding orders.

Get your mug, t-shirt or zipper now: join.gulas.ch

You can also find pictures of the merchandise at entropia.de/GPN24:Merch.

Trolling at GPN24

If you’d like to troll – that’s what we call helping out – you can register now in the Troll System at troll.gulas.ch and become a stakeholder. The most active trolls will also receive a goodie featuring great GPN24 design and the chance to register early for the next GPN. Please don’t forget to tick the relevant box in the Troll System.

Talks, workshops and music

Proposals for talks and workshops can be sent in via Pretalx at cfp.gulas.ch/gpn24/cfp until 26 April. Help promote the event, showcase your skills and gain experience. If you know anyone you’d love to see as a speaker at GPN, feel free to get involved and let them know about this call for submissions!

Talks are usually recorded and posted online at media.ccc.de; you can opt out at any time.

You can submit entries for the lounge via cfp.gulas.ch/gpn24-lounge/cfp by 19 April to enhance the GPN with your music or visuals, creating endless added value.

24th Gulaschprogrammiernacht

Sun, 15 Mar 2026 00:00:00 +0000

gpn24.de – Gulasch at the Scale of Chaos

Entropia cordially invites you to the 24th Gulaschprogrammiernacht under the motto “Gulasch at the Scale of Chaos”!

4–7 June 2026
HfG and ZKM, Lorenzstraße 15, 76135 Karlsruhe

TL;DR:

GPN is an open, donation-funded community event where you can hack together, eat goulash, watch lectures, and more. As with the last GPN, registration is required.

€80,000 – Help us reach this fundraising goal. The GPN is made possible primarily by you and your donations. We need every donation (including yours!) to continue celebrating Goulash Programming Night in the future!

Contrary to our expectations, the GPN has failed to break even in recent years. This year, we need about €80,000 in donations to make GPN24 and future events possible. Registration fees will not cover the costs of the event.

The event only works because, in addition to your donation, you also contribute as a participant, be it by helping with various tasks (“trolling”) or submitting lectures/workshops/meet-ups (click here for the CfP).

Important links

Mandatory registration & merch: https://join.gulas.ch/ (Registration starts on 23 March, 20:00 (CET = UTC+0100) and 29 March, 15:00 (CEST = UTC+0200); Deadline for merch: 3 April)

About GPN

As one of the largest Chaos events, Gulaschprogrammiernacht (GPN for short) offers our participants many opportunities to exchange ideas, gather new impressions, and simply have a great time. To this end, we organize a wide range of lectures, workshops, and music, we set up a large hack center with space for art and crafts, and produce large quantities of Tschunk and, of course, goulash.

Be part of these magical four days, regardless of whether you’ve always been involved in Chaos or have no idea what to expect.

This year, you’re not just the participants that make this event possible, you’re also taking on the role of valued stakeholders of GPN24.de, the super corporation that can do everything. All at the same time!

From long-distance goulash pallet transport to remote data transmission – we no longer just hide the patterns, we’ve productized them, labelled them, and squeezed them into 24-hour service cycles. We invite you to dive deep into this hypercapitalism, ride the flood of information, and examine critically: Do we really need an AI DLC for everything … oh wait, a domain? (Spoiler: Yes!)

In a world of information overload, we offer you the logical synthesis: Everything about everything, around the clock. We have optimized the right interface for every need:

Hungry? Goulash24 (Here I goulash everything!),
Thirsty? Tschunk24 (Here I mix everything!).
Knowledge? Goulashprogrammingnews24 (Here I learn everything!).
Despair? Merch-is-empty24 (Here you can’t get everything!).

Are you ready for total synergy? Then come to GPN24. Here you give everything, here you get everything – except sleep perhaps. We look forward to your projects, your presentations, and your willingness to subject the system to an inside out … well, an optimization!

New here?

First time at GPN?

Here you can watch presentations, participate in workshops, bring your own project, hack, help out, dance to music and visuals in the lounge, get coffee, mate, or Tschunk at the bar, eat goulash and other delicacies, meet and reconnect with people, collect stickers, and much more. At https://gulas.ch/ you will find information about how the event works, with links to further wiki pages on various topics. If you register there, you will receive the latest information by email before and during the event. We always welcome new people and try to create an open atmosphere in which everyone feels comfortable.

Registration

This year, registration for GPN will again be necessary to avoid overcrowding. To allow spontaneous visits to GPN, there will again be a small number of day passes available on site (while supplies last).

Registration and day passes serve to ensure that we do not exceed the capacity limits of the building.

When registering, you can still pre-order T-shirts, mugs, etc. as usual. As you have probably read already, we rely on your donations during registration.

Registration & voucher

To ensure that all slots are filled, we have linked registration to a €10 voucher. It can be used freely at the GPN. This does not constitute admission, but is intended to ensure that registrations are actually used (or cancelled).

Registration without purchasing the voucher is not possible.

If you cancel your registration by June 3, 23:59 CEST (end of day 0), the voucher will be refunded. This will allow another person to attend the GPN.

If you would like to attend the 24th Gulaschprogrammiernacht but are unable to purchase a voucher, please contact us at friends@gulas.ch. If your presentation submission is accepted in the CfP, your registration is guaranteed.

Trolls who helped out sufficiently last year will receive a guaranteed registration if it is redeemed by March 28 at the latest. Before the first registration date, an email will be sent to everyone who gave us their consent last year. For trolls, registration is also possible outside the registration periods.

Day passes

The free day passes are for anyone who only wants to visit GPN for one day or who finds out about GPN spontaneously. Those travelling from further away should not rely on day passes being available, as these are primarily intended for interested persons from Karlsruhe.

There is only a limited number of day passes available. We will provide information on the availability of day passes during the event at https://gulas.ch/ and in the Fediverse at @gulasch@gulas.ch.

Children and minors

Children and minors up to (and including) the age of 16 years can be added to a registration free of charge.

Registration dates

For registration (including purchase of the voucher), we will release quotas at join.gulas.ch at the following times:

Monday, 23 March 2026, 20:00 (CET = UTC+0100)
Sunday, 29 March 2026, 15:00 (CEST = UTC+0200 – including waiting list)

You can also reserve merchandise outside of the registration periods: https://join.gulas.ch/

Unpaid or cancelled registrations will be re-released, so it may be possible to register between the dates – a waiting list will be opened immediately after the last date.

You can find more detailed information on the website and in our FAQ.

Financing the GPN

You’re probably wondering where the figure of €80,000 comes from.

An event with over 2,500 participants adds up to quite a lot. From transport trucks to earplugs to the most comfortable beer benches in chaos. And much more.

Of course, we sell your beloved waffles, goulash, and the best Tschunk. However, we do this not to make money, but because it is part of the GPN. We cannot finance our event from this, as we want to keep prices low and also have to pay taxes on it.

We want to maintain an open & inclusive GPN with the lowest possible prices.

Your donations, on the other hand, go fully towards the event, and you can also claim them in your tax statement.

Those who can donate more invite someone else to the GPN.

The current progress of the fundraising campaign is visible at donate.gulas.ch. If we do not reach our donation goal, we will probably have to cancel the GPN entirely. In that case, we would refund the vouchers and donations for the GPN. If you would like us to use the donations for other charitable purposes at Entropia, please indicate this.

Thank you for making this event possible with your donation!

Lectures and workshops

We want to offer an interesting workshop and lecture programme at the GPN again – for this we need you and your topics! We look forward to talks on a wide range of topics and a broad workshop programme for all participants.

You will soon be able to submit your suggestions in Pretalx at https://cfp.gulas.ch/gpn24/ until 26 April 2026, 23:59 CEST. If you know people who you would definitely like to see as speakers at the GPN, get active and let them know about this call for proposals!

Do you do art or a performance? Bring it to the GPN on the stages of ZKM & HfG Karlsruhe!

Share your ideas, projects, research, art, or other interesting topics in a talk or workshop during the GPN.

We especially want to encourage people who are new to the stage to participate. Not sure if your topic fits the GPN? Just give it a try, or contact us! Get in touch with the content team on Fediverse (@content@gulas.ch) or by email (content@gulas.ch).

The presentations are usually recorded and posted online at media.ccc.de. An opt-out can always be arranged.

Art and Creativity

You can create art and beauty with a computer.
— Hacker ethic

The GPN is hosted at the ZKM (Center for Art and Media) and the HfG (Karlsruhe University of Arts and Design) – a perfect place to combine art and hacking!

Would you like to get creative at the GPN and embellish the event or exhibit your art project? If it is a smaller project, just bring it with you! Anything that does not fit on a small table, needs to be hung up or has special requirements (electricity, internet, etc.)? We will be happy to work with you to make it possible. Contact us at art@gulas.ch!

Music and visuals

If you would like to enrich the GPN with music or visuals, please apply by 19 April 2026 via the CfP for artists.

You can find the corresponding CfP here (will open soon).

For more information, visit https://chaos.social/@LoungeControl.

Trolling

Like all other Chaos events, GPN only works thanks to the energetic efforts of many helpers who keep everything running smoothly, from the info desk to the kitchen to the livestreams. If you want to troll – that’s what we call helping – you will soon be able to register in the troll system. The troll cave is the place to go for those of you who habitually seek out the Heaven. The most active trolls will of course receive a goodie with the GPN24 motif and will have the opportunity to register early for the next GPN. Please don’t forget to check the appropriate box in the troll system. No special prior knowledge is necessary; if needed, there will be an introduction to the respective task or a talk introducing trolling.

https://troll.gulas.ch

Mini FAQ

“How much does a ticket cost?” – There are no tickets.
- When you register for the GPN, you must also purchase a €10 voucher (redeemable at the kitchen and bar). This ensures that registrations are actually used.
- If you are unable to purchase the voucher, please contact friends@gulas.ch and we will find a solution.
- We still rely on your donations; we cannot finance the GPN with the registration package alone. A total of approximately €80,000 in donations is needed to cover the costs of the GPN. You can donate during the registration process.
What happens if I can’t come after all?
- It would be sad if you can’t come to the GPN. You can transfer your registration to someone else or cancel it.
- You will receive a refund for the voucher if you cancel your registration by the day before the event, which makes your registration available to others.
But I only want to attend the GPN on Saturday!
- Day passes are available on site. The availability of day passes will be indicated on the start page at gulas.ch.
Why no tickets?
- An event with tickets is simply not possible in our circumstances.
- We run the event in parallel with university and museum operations, which also brings us great financial benefits.
- Likewise, spontaneous visits with day passes and the open nature of the event would no longer be possible.
- The purpose of the €10 voucher is solely to prevent abuse of the (otherwise free) registration and to enable as many of you as possible to participate.
What are trolls?
- That’s what we call our helpers, comparable to the angels at other Chaos events. Come and troll with us!
Why are you asking for donations so aggressively this year?
- We have made a net loss in recent years, and the existence of the GPN is at stake.
How can I stay informed?
- Check out gulas.ch, follow us in the Fediverse, and sign up – we’ll also send you the most important information by email!
I have other questions!
- First, check out our detailed FAQ https://entropia.de/GPN24:FAQ and if you can’t find the answer there, send us an email.

First InselChaos: Invitation & Call for Participation

Tue, 10 Mar 2026 00:00:00 +0000

The Baltic Sea. Family vacations, nudist beaches, fish sandwiches, sand between your toes and seagulls in the air. For many, it’s a relaxing vacation spot; for us, it’s the best location for the saltiest chaos event in Mecklenburg–Western Pomerania!

After the first InselChaos in 2025 impacted like a seagull on a fish sandwich, we have no choice but to repeat the experience in 2026. Or as visitors would say: “There’s already a postcard waiting for you at C3Post for InselChaos 2026, you have no choice but to come!”

InselChaos 2026 will take place on 4–6 September 2026 at La Grange in Bergen on the beautiful island of Rügen, combining art, hacking, music, and the chaos community. La Grange offers an extraordinary atmosphere for exchanging ideas about technology, society, and creativity, just 20 minutes from the beach on the Baltic Sea. Whether on the stage, in the chill-out area, or in the cozy outdoor space – everyone will find a place and opportunity to express their thoughts and creativity.

Of course, an event like this depends on the Chaos community. In addition to the ticket shop, the Call for Participation is now open. We welcome all kinds of topics and formats, be it lectures, workshops, or whatever else you would like to help to shape. Feel free to write to us – we make (almost) anything possible.

So: Pack your swimming trunks and your favourite microcontrollers and come to InselChaos 2026 on Rügen.

You can find more information on the website and Mastodon.

Easterhegg 2026 – tickets, merch, and more

Mon, 09 Feb 2026 00:00:00 +0000

We will be happy to set the stage for your contribution.

In general, when submitting your contribution, please ensure that the description and title are meaningful. If special equipment, instructions, or a limit to the number of participants are important for your submission, please indicate this directly with your submission. This will allow us to support you directly with your submission and make all necessary preparations with you.

More information can be found on our website: eh23.easterhegg.eu and in our CfP: pretalx.eh23.easterhegg.eu/eh23/cfp

39C3: Feedback and lost+found

Tue, 13 Jan 2026 06:00:00 +0000

39C3 is over. Sadly. We hope that your journey home went well and that you had a good return to reality.

Those four days of living a utopia were far too short. There was so much more that one could have experienced, so many more things to discover, so many more people to meet, so many more talks to see … To our own regret, the length of the event can’t really be changed. But many other things can be! That is why we want to ask for your feedback. Let us know what you liked, but also what you didn’t like. We appreciate both praise and constructive suggestions for improvement! But you need to be quick: The hub will be put into archive mode on 20 January (exact time not yet determined). Once this happens, access to the hub will be read-only and feedback can no longer be submitted.

On the other hand, four days is enough time to lose quite a lot of things. But not to worry: The great team at the coat check has been looking after found items following the event. If you lost something during the event at CCH, you’re welcome to contact 39c3@c3lf.de. If you do, please describe the lost item as exactly as possible and attach a picture if possible to help us find it.
