I can point to individual sentences that were clearly generated by AI (for example, numerous instances of this parallel construction, "No warning. No error. Just different methods that make no sense.", "Not corrupted. Not misaligned. Not reading wrong offsets.", "Not a segfault. Not the T_NONE error from #1079. There it is, the exact error from production"). The style is list-heavy, including lists used for conditionals, and full of random bolding, both characteristic of AI-generated text. And there are a number of other tells as well.

The reason I don't usually bother to bring these specific things up is that I already know the response, which is just going to be you arguing that a human could have written this way, too. Which is true. The point is that if you read the collective whole of the article, it is very clear that it was composed with the aid of AI, regardless of whether any single part of it could be defensibly written by a human. I'd add that sometimes, the writing of people who interact heavily with LLMs all day starts to resemble LLM writing (a phenomenon I don't think people talk enough about), but usually not to this extent.

This doesn't mean that the entire article was written by an LLM, nor does it mean that there's not useful information in it. Regardless, given the amount of low effort LLM-generated spam that makes it onto HN, I think it is fairly defensible to use "this was written with the help of an LLM, and the person posting it did not even bother to edit the article to make that less obvious" as a heuristic to not bother wasting more time on an article.
