So, anyone built an x like for you feed based on what they published? Would be curious how this works on Bluesky www.heise.de/en/news/X-ma...

X makes timeline algorithms open source – and promises transparency

There has been much speculation about how X decides which posts end up in the algorithmic timelines. Now you can check it yourself.

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...

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
