Or, "how I learned about the phrase 'nasal demons' and its relevance to C code review¹.
I landed up asking an LLM tool to review complex, experimental work in progress "in the style of a very prominent Linux kernel developer having a very bad day".
So an out-of-tree extension author gets the rule wrong, the unwind callback dereferences a stack frame that has been unwound, you get nasal demons. And there is no diagnostic.
and
[...] logs the drop count once per minute and zeros it. No cumulative drop counter is exported as a metric — the extension cannot instrument itself. The on-call engineer has to scrape the postgres log to find out the OpenTelemetry pipeline is dropping data, which is a Heller-class irony.
The review was surprisingly good, especially from an statistics engine with delusions of grandeur. The results were hilarious ... but they were also the most useful LLM code review result I've ever managed to obtain.
