We think Europe needs more pro-European, pro-tech, pro-abundance, pro-optimism propaganda. So we made it.

Posters, t-shirts, hoodies. Full-on propaganda. We've been handing them out at robotics meetups and clubs all over Europe for weeks, and people love them.

Why we are doing this: Europeans know more about the companies in the States than the ones right here at home. We need to change that. Time for propaganda.

Every poster features a real European company:
🦾 Allonic is braiding humanoids. A completely new approach to building robotic parts. If it works, a number one company worldwide, right here in Europe.
🚜 Voltrac, the electric autonomous tractor (we made a whole video about them).
🏗️ Automated Architecture (AUAR), doing micro-factories for wooden houses. 
🪨 Gondor Industries, a stone mason company using robotics.

And many, many more to come.

This is the first of many drops. More launching in the next few weeks, including flags, EU posters and more.

For Europe 🇪🇺🔥

PS: If you're organizing a robotics event or meetup, have a student club or hacker space, comment or message us and we'll send you a swag box.

I always wondered how session replay tools like PostHog, Sentry, and LogRocket play back what a user did on a page, so I dug in.

They mostly don't record the screen as video. Tools like rrweb record the DOM and reconstruct it. Here's how.

🧑‍💻 @AnthropicAI × @ETH_en AI Sprint: a couple days ago, we brought together 45 selected participants from the @ethaiclub and @ETH_AI_Center across 17 teams for a 1-day sprint with @AnthropicAI! Goal: make the most progress in a day, with a CHF 6k ($8k) prize pool on the line. 🏁

[Arnout Devos @ArnoutDevos]

Also made it https://t.co/BoaG1YjL6t! @claudeai Opus 4.8 is most accurate for me, and only a bit outdated (approx. up to June 2024).

The other models think I'm either an economics researcher, a politician, or a cyclist. Caveat: prompt is only the full name.

Not sure what's happening under the hood, but the result seems quite prompt sensitive. gpt-5.5 thinks I'm still at Stanford🤷
