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.

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 💸

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

have been using codex quite a bit for coding recently and its quite good - still pretty shit in terms of ui design taste though

Hamburg rush hour.
Backlit silhouettes of a coxed four rowing across the Alster in Hamburg on a bright morning, with a goose family — two adults and three goslings — paddling in the foreground. The water sparkles with sun, and a tree-lined shoreline sits in the distance.​​​​​​​​​​​​​​​​

Codex 5.4 design taste is still weird 😂 Also, spent at least as much time walking codex back to what I actually wanted as it spent excitedly building complex abstractions I didnt want

asked claude to roast a website 🔥 > The footer. Xing. In 2026. The Nokia 3310 of social networks. That alone tells me the target persona is a 54-year-old Head of Digital who still prints his emails.
