Notes
Shorter pieces.
Individual problems worth writing down — usually because the obvious solution was wrong, or because the failure mode was invisible.
- Infrastructure
My development environment is a server
One always-on machine, provisioned like production, that is simultaneously a warm CI runner and the place I actually work — why, and what it cost.
- Cost engineering
When cost is the architecture
A generated-audio product where each session cost real money to produce, and the caching design that followed — including the failure mode that would have been invisible until the bill arrived.
- Open source
A compiler for agent context
Code that lies gets caught by a compiler. The instruction files we hand coding agents get executed instead. groundtruth turns those claims into assertions that fail in CI.
