I go one level down when a problem resists.

AI architectures, CPU inference, Rust, assembly when it is needed. I write the articles I wish I had read. Soon, the courses that go with them.

One level down: #000 an inference engine that writes its own code

I am opening a series on Herbert, an inference engine whose entire computation is written as machine code at startup, for the processor it runs on. What it is, what I am going to publish and what the series will measure.
