For those interested in hash tables I found the Hash Tables section of Crafting Interpreters pretty good[0]. It has a section on hashing, which supplemented with this SE post[1], I've found to be comprehensive enough. Of course, if you aren't familar with binary/basic bit manipulation, you may still find the internals of the hashing functions mentioned slightly confusing.
