Nuclear Design Bureau has come a long way since it's initial release, now we have physics improvements, leaderboards, challenge missions and a whole host of physics visualizations modes for you simulations. I'm amused at how this can stress your GPU while looking like this:

I want Slow Reader to set new standards for protecting users. It's open source, local-first, and end-to-end encrypted. But how can you prove a website was actually built from its published source code? Thread ↓ hplush.gitlab.io/slowreader-…

The verifier itself is intentionally simple: no dependencies, with literally every line of code commented. You can audit it yourself (or ask an LLM to help). It's designed to keep running automatically, without my involvement.

I want to go even further: a browser extension or mobile app could verify that every connection reaches a server running the expected Docker image. There's a cool technology for that: hardware attestation, where a CPU can prove what's running. But that's for later.

🚨 LiteLLM, a Python package for connecting to AI model providers with 92M+ monthly downloads, has been compromised. Version 1.107.0 ships credential-stealing malware through PyPI wheels and Docker images, targeting cloud credentials, developer secrets, and AI tools.

If you moved to Barcelona on a highly qualified professional visa, there's a city service that can help you navigate bureaucracy in English. I know someone who got a TIE appointment through them in just a couple of days. barcelona.cat/internationalw…

I'm building Slow Reader to read more useful threads, not rage bait. I liked Bluesky's cute thread indicator, so I added it to the UI. It'll work across all social networks, with more UX tweaks and gamification to help break bad scrolling habits. slowreader.app/

While people stuck in Musk’s algorithmic bubble think the EU has no AI, France’s Mistral just unveiled Large 4, competitive with top Chinese open-weight models. The EU also has strong OCR and video generation models, plus promising AI chip startups like axelera.ai/

Donald Trump’s friends (russian army) killed an infant in a park in the Kharkiv region today. I truly hope Americans see this and draw their own conclusions.

I added Mastodon and Bluesky to Slow Reader. You can now read friends’ posts without an account. Reading your full home feed with an account is coming later this week. dev.slowreader.app Check that we display your posts correctly if you have an account on either platform.

Barcelona has a strong anarchist tradition. For example, there's a cooperative internet provider called Som Connexió. You're not just a customer. You're also a co-owner, with a small but real say in how the business is run. somconnexio.coop/

Want an even more anarchic internet without censorship? Barcelona has eXO, a project where people started their own small ISP with their own network links. No La Liga blocks (the ones that break Docker on weekends), because they're independent. exo.cat/

Orca's architecture hasn't changed since 2006. Mine eats 100k events/sec and still answers in under a millisecond. Built gorca — a Linux screen reader, Rust, from scratch. @gnome @rustlang, race me. github.com/Ravino/gorca #a11y #Rust #OpenSource
