The time has finally come: We want to invite you to the 21st Gulaschprogrammiernacht!

Save the date: 08.06.2023 - 11.06.2023 at HfG and ZKM, Lorenzstr. 15, 76135 Karlsruhe, Baden, Baden-Wuerttemberg, Europe, Earth, Sun, α-Quadrant, Milky Way, Laniakea.

You will find anything the hearts of hackers and haecksen long for at the Gulaschprogrammiernacht: talks, workshops, a demo show, blinkenlights, a big hackcenter, Karlsruhe’s yearly supply of mate and Tschunk, an epic lounge, a wonderful lava meadow, and of course … wonderful goulash! As always, four days of hacking, lecturing, tinkering, and discussing await you. Everybody is welcome, from the usual suspects to the (as of yet) inexperienced first-timers.

Lectures and workshops

The amount of talks and workshops that are going to be held is completely up to you, as is their content! We are looking forward to a wide range of topics for talks and workshops aimed at all participants. You can submit your very own proposals through Pretalx. If you do not want to get up on stage yourself, but know people you would enjoy to see as speakers at the GPN, please forward this call for participation to them. Remember to make your presentations and workshops as accessible and understandable as possible. Presentations will be recorded by default and posted online at media.ccc.de, opt-out is possible at any time.

“lack (noun, singular/uncountable) A situation in which you do not have any, or enough, of something that you need or want.” (from: Macmillan Dictionary) The increasing lack of computer chips puts all of us electronic machines wielding people in a difficult place: On the one hand, we wish to source cheap hardware, on the other hand we strive for better supply chains so as to not aggravate the environment’s condition any further. In call, switching to alternatives that serve both goals is an inevitable development. Notably, open-source based projects have proven to ameliorate our society, even if the majority of people are unaware of this manner of collaboration. It is our responsibility to rethink, redraft, and rebuild our prior designs and come up with solutions suited to current challenges. Raise a Mate to more affordable and sustainable hardware—let us develop ch(ea|i)p alternatives!

We would very much like to encourage you to hand in talks, even if you consider yourself an inexperienced speaker. Should you be in need of any help, simply reach out to us and we will provide you with assistance as best as we can!


The GPN, like all other Chaos events, is only possible thanks to the energetic efforts of many helpers who keep everything running, from the info desk to the live-streams. If you want to lend a hand, you can pre-register starting now by joining troll system. Those amongst the most diligent and active will receive a thank you in form of our iconic bowl with the GPN21 design—an item reserved exclusively for helpers. But that is not all: Let us surprise you with other goodies as well. For certain specialised activities, newcomers will be receive a brief introduction, so that no previous knowledge or special qualifications are necessary even for the fanciest of shifts.

For anything else, consult the Internet: Follow the goulash.


  • “How much is a ticket?” — There are no tickets and admission is free. GPN is donor-funded and prices for drinks and food are deliberately kept as low as possible. We rely on your donations to make this year’s (and any further) event a reality.
  • “Why should I register?” — It helps us plan how many chairs, tables, goulash, and tschunk ingredients we have to provide for. Textile swag must be reserved at the time of registration. Also, by registering, you will get a free public transport ticket for the duration of the event.
  • “What are trolls?” — That is the name of our helpers, comparable to “angels” at other chaos events. Come by and be a troll!
  • “I have other questions!” — If you have not found your answer in our detailed FAQ, drop us a message.
