Before I could make sense of attention code, I needed PyTorch's tiny tensor vocabulary to stop feeling mysterious. This first session covers shapes, axes, batching, and the important difference between stack, cat, multiplication, and dot products.
I had Anthropic's always-on security plugin installed for a month and assumed it was reviewing every turn. Its own log said otherwise. What each layer actually does, how far its configuration goes, and the one hook that says no.
I opened a FastAPI file as a Spring engineer and kept noticing what wasn't there: no MapStruct mapper, no @Valid, no springdoc. The type signature had already done the work.
The same engine powers Flask pages, Ansible playbooks and static sites. Here is Jinja2 learned from the engine out - delimiters, autoescaping, inheritance and the Environment - with every concept run by hand, coming from the JVM.

Kyutai's Pocket TTS is a 100M-param, CPU-only text-to-speech model that does zero-shot voice cloning. Getting it to clone my voice took one afternoon — two gotchas worth writing down (uvx isolation and the mp4 trap), plus a Claude Code skill so I can trigger it mid-session.
