$ cat README
Debugging stories, terminal setups and small tools I keep rewriting. Nothing here is a tutorial; most of it is a log of things that broke.
A cron-triggered report opened a channel nobody closed. It only ran once a week, so the heap graph looked like a staircase with very long steps. pprof found it in four minutes; I spent three weeks not looking.
Lesson, again: if something grows on a schedule, list what runs on that schedule before blaming the allocator.
The git status segment walked the whole repository on every keystroke. Moving it to an async worker and caching by HEAD hash removed almost all of the lag. The theme stayed the same: amber on near-black, because my eyes asked for it.
Plain text file, one task per line, a tag for the day. The script prints today's lines in magenta and yesterday's leftovers in dim grey. It is ugly and I use it every morning.
USB resets, thermal throttling, a disk that complains only when the room is warm. Keeping a week of kernel logs side by side made the pattern obvious: the laptop was fine, the dock was not.
Backend developer. Writes Go and Python for a living, shell scripts for fun. Works best with the lights off and a slow playlist on.
The dotfiles archive above is the current snapshot of my terminal setup.
