@skorfmann.comBuilt 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.

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.

@skorfmann.comA 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

@skorfmann.comDynamic Workflows in Claude Code to non coding problems are superb for fanning out 100s of subagents in minutes.

@skorfmann.comrunning codex in multiple subsequent "/goal" loops for the last 24 hours - so far no limit in sight

@skorfmann.comhalf 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 💸

@skorfmann.comShipped 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

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

@skorfmann.comBuilt 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...

@skorfmann.comCodex 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
