Lightning Talks
summary
Four short demos: a home lighting controller written in 4,000 lines of Go with a CLI, YAML config, discoD web UI and ~1,000 lines mapping xkcd color names; a history of flame graphs (100 Hz sampling, x-axis ordering trick) with the practical tip to print one for production; a GJSON pitfall where repeated key lookups blow CPU and switching to a fast indexed parser moves p50 to p95; and a Bubble Tea TUI workflow with a Tetris prototype built in two days.
