Error ABI
Nov 9, 2025 A follow-up on the “strongly typed error codes” article. One common argument about using algebraic data types for errors is that: Error information is only filled in when an error occurs, And errors happen rarely, on the cold path, Therefore, filling in the diagnostic information is essentially free, a zero cost abstraction.

Open source has a growing problem with LLM generated issues
We’ve seen a slight uptick in pull-requests and bug reports which appear to be LLM-generated, so it’s probably about time to come to a decision on what we should and should not accept and document this somewhere (presumably in CONTRIBUTING.md).

Photo by Monroe County Sheriff’s Department, via New York Times Tesla has engaged in a pattern of taking credit for the successes of its Full Self-Driving (FSD) software, even though the car still relies on an attentive driver, and yet blaming the driver rather than the software whenever things go badly.
