I became a software engineer because writing code is fun. Thinking through hard problems, designing elegant solutions, seeing the things you’ve built working for the first time… these moments are all deeply satisfying, so why in the world would I ever surrender them to AI?

More work on UringMachine benchmarks. This validates the work of @ioquatix.bsky.social on the fiber scheduler. We see a marked performance advantage to using Ruby fibers for any I/O-bound workload, including querying PostgreSQL databases.

This is our biggest release yet. Rack 3, resource routes, and so much more.
