Thoughts, notes, and things I'm learning.

Hello, World

July 24, 2026

This is my very first post. I'm starting this blog to keep track of things I'm working on and ideas worth writing down. No fancy setup here — just plain HTML, so it's easy to edit and easy to host anywhere.

WASM Demo: Mandelbrot Explorer

A small WebAssembly module, live on this page

This fractal is rendered by a ~1KB WebAssembly module compiled straight from Rust with rustc (no JS framework, no build step). Click the fractal to zoom in.

WASM Demo: Bouncing Ball Physics

Gravity, wall bounces, and elastic collisions — simulated in WebAssembly

Another tiny Rust→WASM module (~1.4KB). Every frame, WebAssembly integrates gravity, resolves wall collisions, and checks all ball-vs-ball pairs for elastic collisions — JavaScript just reads the resulting positions out of WASM linear memory and draws circles. Click anywhere to drop in a new ball.

Why I Keep Things Simple

July 20, 2026

I don't need a CMS or a database to write a blog. A single HTML file does the job just fine, and I can add new posts whenever I want by copying a block and changing the text.

What's Next

Future posts will probably cover whatever I'm building or reading about at the time. Stay tuned.
