Hash tables are cool but they are far from being the only thing you need.

The problem with this kind of subtle satire without a disclaimer at the end is that some people would fall by this and blindly follow it (collisions weren't mentioned not even once nor cache misses).

I don't think the satire was particularly subtle!

Given the number of comments with "Please tell me this is a satire" in this thread, I would say it wasn't particularly explicit.

Then they obviously didn't read to the end:

"Unlike most academic work that has little to no practical implications, I think blindly following the stuff here will prove to be incalculably beneficial for you."
