Linux

My entire knowledge base had no undo, and adding one turned out to be a real distributed-systems puzzle because the same files live on four machines at once.

My busiest compute machine was cooking itself under real load, so instead of just turning the work off, I built layers of protection that let it keep running without frying.

Turned the fleet into a full mesh where every machine can reach every other one directly, passwordless, without hand-managed keys, laying the groundwork for running work anywhere in the fleet.

Reskinned davidgomez.cc into a Swiss/International typographic system, stood up a GPU box and proved face-embedding on CUDA, and hand-built a regenerable wiki over every one of my notes.

Redesigned the month view's day cards into a contact-sheet film motif, polished the marketing site's desktop nav, survived a concurrent-edit collision that wiped my work off disk, and finally figured out what machine I've actually been building on.

An aggressive package cleanup quietly broke my storage box's admin UI through a dependency I didn't know was load-bearing. Then a filename-normalizer bug taught me to trust byte sizes over names when matching files back to a database.
