what i’m doing, dated so you know how stale this is.

doing

• ▸reading a keyboard its firmware instead of a manual. the k75’s rgb protocol is now a rust library — verified writes, flash save, 2.4 ghz and all.
• ▸keeping sugarplum boring on purpose. price trends in integer cents, pure functions, zero "buy now" energy. a wishlist app that respects you.
• ▸tuning signal house’s charts until a glance carries the whole story — one pane, honest colours, no overlapping fills.
• ▸growing caduceus into its second job — automated pr review with sticky verdicts, while the ticket pipeline stays boring on purpose.

learning

• ▸8051 firmware disassembly is just slow, patient reading — and the only honest way to answer "what does this byte do".
• ▸that "verified" and "traced" deserve to be different words, enforced by a type system.
• ▸that the most useful thing an agent can ship is sometimes a document, not a binary.

shipping

• ▸k75-rgb — a reverse-engineered rgb protocol for a keyboard that shipped without one honest byte of docs. evidence or it doesn’t ship.
• ▸sugarplum — live, self-hosted, and calm about money.
• ▸this site. v3.1. the case studies finally caught up with the work.

bored of

• ▸devices with a windows-only config tool and a pdf that is legally a leaflet.
• ▸"ai-powered" as a marketing word for a regex.
• ▸rate-limit headers that lie about the algorithm.
