Writing / Field notes
Bugs worth remembering
Postmortems, mostly. The bugs that taught me something worth writing down, explained properly with the diagrams I wish I had when I hit them.
Dispatches
02 notes- Note 01
What broke when 1,769 files met Next.js 16
We skipped a major version across a large financial application. The compiler found the obvious breaks; the dangerous ones were valid code with different meaning.
Next.jsReactMigrationMonorepo - Note 02
Twenty-five queues, one core
A job indexed 601 chunks, finished, and was marked failed. Three times. What that taught me about event loops, lock renewal, and health signals that starve themselves.
