The new Sternbrücke is on the move: 108 m long, 4,500 tonnes, rolled through Altona to replace a bridge from 1926. There’s a livestream. #hamburg www.eisenbahnbruecken-ehm.de/sternbruecke...
this got so annoying that I'm back to codex for coding projects
So Anthropic keeps „relaunching“ Fable every week now, or what is this about?
Very happy to announce that @chatto.run, the amazing little team chat app you can self-host from your own infrastructure (and quite easily so), is now available & Open Source. ✨
Chatto is now Open Source!
The snappiest chat application you've ever used is now available for self-hosting.

For testing out a few inference providers for #GLM5.2, I created a new #Pi extension for Euro provider #TensorX. They have a smol selection of models (tensorx.ai/models/), but what they serve, they serve *fast*. 200+ tps, constantly. Nice! github.com/czottmann/pi... #LLM

Next generation of intelligence for the hardest knowledge work and coding problems.

Using "dynamic workflows" in claude a bit too intense I guess > API Error: Server is temporarily limiting requests (not your usage limit) · Rate limited
Built a tiny browser engine for fun 🦀 → 🕸️ It parses, styles, lays out (taffy), scripts (QuickJS) and paints (tiny-skia) HTML/CSS/JS entirely inside WebAssembly. The browser never sees the markup - only pixels come back out. jot.skorfmann.com/prism-render...
Prism — a browser engine inside WebAssembly
An experimental, for-fun prototype: a from-scratch HTML/CSS/JS rendering engine in Rust + WASM (partial coverage, not yet open source), explained interactively — with live demos of the real renderer.

A fun experiment I'm pursuing with Codex, building a simple browser rendering engine within a browser via Rust / WASM - Latest and most sophisticated take so far: play a video file with sound and do all the work in wasm. Codex runs for more than 16 hours already, and it's getting there
Dynamic Workflows in Claude Code to non coding problems are superb for fanning out 100s of subagents in minutes.
running codex in multiple subsequent "/goal" loops for the last 24 hours - so far no limit in sight
half a day of in depth code analysis from various angles of a handful of repositories via Claude Code using an API key is worth a Claude Max subscription 💸
In other news: wir sind jetzt dauercamper an der Lübecker Bucht 😅🏝️
Shipped a full music video end-to-end with AI: song from Suno, scenes from Seedance, lip-sync via another model, orchestrated from Claude Code. Wild what a bit of AI plumbing gets you these days. Heres the teaser

Possibly the worst restaurant website I’ve seen so far - with forced ads in order to see the menu or go to the checkout 😳 speisekartenweb.de/restaurants/...

have been using codex quite a bit for coding recently and its quite good - still pretty shit in terms of ui design taste though
Built a simple durable workflow thing on top of Rails primitives - keep coming back to this kind of problem and didn't wana add a separate service. Building this took like 3 hours from drafting a concept to published gem - will start using over the next days github.com/skorfmann/du...
