Minimal perfect hashtables are awesome. I use it in btcs (my bitcoin script interpreter) for mapping opcode names to the opcodes themselves when parsing. It works great when you have a fixed dictionary, like the words in a note. It also uses minimal space so we can pack it nicely within nostrdb as an optimized datastructure for checking if a note contains a word. #nerdstr
