I had the luck to have Fabiano Botelho — the person behind the Minimal Perfect Hash thesis — as an Algorithms and Data Structures professor back when I was studying Computer Engineering at CEFET-MG. He is absolutely brilliant, and has some incredible knowledge on both the theoretical and practical aspects of using hash tables.

IIRC, he had just finished publishing his thesis, and had each of us write our own implementations of minimal perfect hashing for extra credit. The data structure is really useful for indexing large, immutable data sets.
