Rendering Real-Time 3D Before GPUs
How I built real-time 3D rendering on a slow 486 with only 256 colors in VGA Mode 13h, using fixed-point math, palette quantization, matcap-style Phong lighting, and x86 assembly.

React Native in 2026
React Native is an excellent development platform again. Here is what changed since AirBNB moved off of it in 2018, how its New Architecture works, and where the Expo framework fits in.
Web 3D Survey v2
Web 3D Survey v2 rebuilds the site on TanStack Start, adds homepage support summaries, WGSL and adapter reporting, browser capability stats, and a live /machine report.
Adventures in Fluid Simulation
I spent ten years building fluid simulation tools for VFX: a three-day Stable Fluids prototype, sparse level sets for Scooby-Doo 2, tetrahedral and vortex solvers at Exocortex, and three pieces of my software on Harry Potter and the Deathly Hallows.
Frameworks vs. Toolkits for Multi-Market SaaS
Why SaaS products that stretch one opinionated framework across multiple markets often become harder to use, and why scalable multi-market products separate universal toolkit primitives from market-specific frameworks.
My Dad, an Apple IIe and a Stack of Nibble Magazines
My dad bought an Apple IIe and a stack of Nibble Magazines. This was the start of my career in computer graphics.
Optimizing TanStack Start for Cloud Run
TanStack Start runs on Nitro, and Nitro's default Node output can split server code across many files. On Google Cloud Run, that file fan-out can add seconds to cold starts. Bundling the server and pre-warming Node's compile cache reduced first render time on this site.
A Solution to Rampant Token Theft: Proof of Possession
Static API keys in environment variables and files are too easy to steal. A better model is proof-of-possession, where every API call must be signed by a non-exportable private key that is available only through a constrained signing interface.
React Internals
Understand what React is doing when your components render, pause, skip work, commit to different hosts, hydrate server HTML, split work with Server Components, and hand animation off between frames.
Introducing vitest-command-line
Testing command-line tools is deceptively hard - hanging processes, lost stderr, temp file juggling, and unreadable failures. I built vitest-command-line to make CLI testing in Vitest simple and robust.
React Server Components
Part 7 of the React Internals series. React Server Components split a tree into server-only and client-interactive pieces, serialize the server result as an RSC payload, and still rely on SSR and hydration for the Client Components that reach the browser.
Server-Side Rendering and Hydration
Part 6 of the React Internals series. Server-side rendering creates an initial HTML snapshot on the server; hydration lets react-dom attach event handlers and fibers to that existing DOM instead of replacing it.
