That post comes uncomfortably close to how Opus writes this kind of prose. It's a good idea to acknowledge all stakeholders.

After your comment I went to original and it really looks like ai assisted rewrite with prompt like “give more explanations about basic concepts”…

And? How does it matter when what you’re saying is fake? I’m so tired of online people emitting false accusations like that. It’s not because some people do it than everyone does it. I wrote a book called 100 Go Mistakes even before LLMs existed. I wrote on blogs for more than 15 years. At some point, this is just insulting.

I used that post as a source yes, and it’s stated explicitly but it’s not the only one. One section in particular is similar since we both present the different preemption modes. However, both audiences are different. thebuild.com has an audience composed of PostgreSQL enthusiasts (if not experts) and I don’t. So a significant part of my post was about explaining things from first principles (what’s a page, a TLB, a spinlock, etc.). I explain way more “basic” things and he goes beyond me in terms of how to cope with the problem. I don’t think the posts are closed.
