Brilliant article, thanks for posting.

This is typically the kind of post which makes me want to actually apply, mostly because I can relate to it : it's not magical, doesn't require gazillions of tpus, or petabytes of storage : it's plain old, excellent engineering.

I wonder how often these issues creep up in practice, and how long it took the author to sort it out though! I've had my share of compiler bugs/kernel bugs, and they're usually quite expensive to understand, and it takes a long time to convince yourself that the bug is not in your code (granted, there's an oops here!)
