Notes from
the workbench.

How the things on this site are built — the music toy, the local models, the Mac station — written up as I go.

26 SEP 2026Making an AI write one song, not ten ideasWhy LLM-generated music sounds like a chain of unrelated ideas, and the four structural rules Tunepick uses to make it sound like one song.
25 SEP 2026Three options are not one prompt run three timesHow Tunepick gets three genuinely different choices out of a language model: a brief per slot, rotating briefs, a similarity score, and one targeted re-ask.
24 SEP 2026Running a 27B model on my Mac every dayMy setup for running Qwen3.8-27B locally with MLX: 4-bit weights, thinking modes, real speed and memory numbers, and a same-origin proxy so it streams to an iPhone.
23 SEP 2026A job queue where a restart loses nothingDesign notes from eki, my Mac station for local models and coding agents: stateless engine, detached workers, one SQLite file, and routing that explains itself.
22 SEP 2026A guestbook with no words in itHow the melody guestbook on zxa233.com works: eight notes on a pentatonic scale, a tiny Cloudflare Worker, KV storage, and rate limiting without storing IP addresses.
