The notation itself sucks and anyone taking pride in the ability to parse it is suffering from Stockholm syndrome. It's also one of the most annoying things to look up because search engines ignore the symbols. AI can explain it based on a screenshot now, but then we might as well go to AI for the entire thing and I'm starting to lean in that direction just to spite authors like OP. You're also connecting the syntax to understanding of the concepts which is the cherry on top of the math snobbery in this thread. If the blog had pseudo-code instead of 18th century scribbles, the HN crowd would at least not openly admit to any parts they don't understand, because it's implied that you can code when you post here - not so much that you give a flying f--- about math or really anything theoretical.
