The @vercel.com MCP adapter works with @val.town HTTP triggers (for streamable HTTP at least) meaning you can write and deploy MCP servers with TypeScript instantly, right in your browser!

When testing @pipecat.bsky.social examples with their prebuilt UI, you can manually submit user messages (or trigger other behavior of your choice) through the browser console via app messages by including a handler like this.

I love how easy it is to add observability to Effect programs. To avoid overloading my computer I split the data into batches to embed/upload, Effect made it easy to compose this behavior and monitor each step.

A few years ago I published an interactive visual explanation of MVP matrix transformations in #threejs vertex shaders. The original CodeSandbox project broke, so I moved it to a more stable home on GitHub Pages.
