Thank you Michael Rabin for your excellent work. Rest in Peace.
Rabin Fingerprinting is one of my favorites of his contributions. It's a "rolling hash" that allows you to quickly compute a 32-bit (or larger) hash at *every* byte offset of a file. It is used most notably to do file block matching/deduplication when those matching blocks can be at any offset. It's tragically underappreciated.
I've been meaning to write up a tutorial as part of my Galois Field series. Someday..
