Originally for this year's easterhegg, @traumweh and I have created a tool, that allows for easy comparison of merch measurements from various past and future Chaos events. We hope this'll help you to determine which size most likely fits you best:

https://merch.chaos-nah.sh

So far we have added merch from gpn23 and WHY Camp 2025 - please note that we have no connection to the events and the information in the tool is without guarantee.

100 days left!
Will we see you in August?

August 8 - August 12 #WHY2025
There are around 500 tickets left, so get them while you still can
(and also grab your Merch while you're there!)

Dieses "in Köln" eröffent schon nette Optionen, da Bonn nur ein Hüpfer ist. :D

WHY2025 goes camper-only!

No tents—just 3,500 hackers in vans, caravans & cybertrucks.
Think barcades-on-wheels, mobile raves & family camper villages.
Time to pimp your ride.

I did the thing! #WHY2025

My highlights from #HackadayEurope last weekend:

- History of the Dutch hacker camps (e.g. predecessors of #why2025): https://www.youtube.com/watch?v=V-UoctcYa88
- NFC-based payment system for a festival: https://www.youtube.com/watch?v=0sE78ekHIJk
- More recyclable or even compostable electronics: https://www.youtube.com/watch?v=rG-R48RJ9Iw
- Using IR cameras to look inside microchips: https://www.youtube.com/watch?v=8aLW4UEuJ_c
- Neonpixels, old-skool core memory and 6502 processor (perfect to learn microcontrollers): https://www.youtube.com/watch?v=Gw9w2a9JBvY

I really don't understand the die hard #trump fans who end up on my #scoopz insulting me.

Even people in conservative town hall meetings are booing Trump, and so they must be the ones who never actually watch News, and just blindly believe everything Trump tells them.

The only insult they know is to call me gay, or say I have a big forehead. As if every bald person ever hasn't heard that.
