That is one explanation. The alternative explanation is that someone found something cool and decided to write a blog post. How many front-page posts have there been on some algorithm or bloom filters or seemingly "advanced cool stuff" that people have already figured out decades ago?

Yes. But I think the point the comment (that I was commenting on) was getting at was that there are in fact refernece points that should have been mentioned for completeness.

That void is either intentional. Not good. Or due to a lack of awareness (or the obvious). Again, not good.

Or, neither? There are alternate benign interpretations which admittedly are very non-dramatic and boring. I've found that people are most often neither malicious nor stupid.
