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 …

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.

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 …

After the closing, assemblies start emptying their spaces. Please take the time to tear down in an orderly and mindful way. Clear your tables quickly so that the Møbelhaus can carry tables and chairs away and that network and power infrastructure can …
