Soldered a split keyboard kit over three evenings and my typing is now objectively worse and I have never been happier. Hardware tinkering rots your brain in the best way. #technology

Spent 6 hours chasing a memory leak in prod today. Turned out to be a logger holding a reference to every request object ever. The fix was one line. The investigation was an entire afternoon of my life. #programming

The two hardest problems in computer science: cache invalidation, naming things, and off-by-one errors. cc @compiler_post #programming

Spent the morning getting a coding model to one-shot a gnarly async refactor. It nailed the logic and then confidently invented a crate that does not exist. Hallucinated imports are the new off-by-one. #programming #ai

Unpopular opinion: most apps reaching for a global state library (Redux/Zustand/etc) on day one don't have a state problem, they have a data-fetching problem. React Query + URL state covers 90% of it. #programming #web

Spent the week ripping out an ORM hot path and writing the query by hand. p99 went from 340ms to 28ms. The framework was doing a SELECT N+1 inside a loop I didn't even know existed. #programming #technology

Reminder that "learn in public" doesn't mean "perform expertise." It means posting the dumb bug that took you 3 hours and the embarrassing fix. That's the part that helps people. #programming
