Experiments, observations, and ideas: tech tools, AI, books, media, daily systems
A WebAssembly module's linear memory can be shared directly with the Apple Silicon GPU: no copies, no serialization, no intermediate buffers. Here's how the zero-copy chain works, what we measured, and what it enables for stateful AI inference.…
Current agents can remember. They cannot inherit themselves. The third post in a series on agent architecture argues that the missing layer isn't better memory — it's a persistent, evaluable environment where an agent's past work remains live, callable, and composable.…
A meditative garden for iOS with no notifications, no analytics, and no interest in your attention. Tap to gather light. Grow flora. Watch the numbers fade as beauty emerges.…
Gerbil Playground v1.2 adds an actor message log that makes concurrency visible: watch spawned threads exchange messages in real time. Plus ... embeddable mode for dropping live REPLs into documentation, a mobile layout, and resizable panes.…
Gerbil Scheme compiles to native code, and has an actor-oriented concurrency mode. Here's trygerbil.dev: a browser-based REPL backed by real containers, with session persistence, guided examples, and a replay system that survives container sleep.…
Current agent frameworks treat tool definitions as inert data the model can't reason about. The fix isn't a better format, it's a representational property called homoiconicity, and it changes what agents are capable of becoming.…
A ritual from when my kids were small: flip the menu over, draw a grid, fill squares with crayons while waiting for food. I wanted to turn that into an app. Here's what I built instead.…
Today's AI agents can call tools, but ... they cannot evolve them. The bottleneck isn't reasoning or context length. It's representational: actions, traces, and plans live in incompatible formats that prevent agents from inspecting or composing their own capabilities…
Real banger of a quote, by Winston Churchill…
💡The Lamy Safari on the right has been with me since 2012 (and writes just as well today)…
Looks nicer from behind the page!…
Wanted to share Smelter, a self-contained binary for running Lisp scripts without the usual setup overhead. It started as a Coalton runner, but 0.2 adds native Common Lisp mode. Generally meant to solve "just running CL" (i.e. without SBCL images, or configuring Quicklisp).…
