Nice article. Easy to argue about the details, because the author is describing what they've discovered or bumped into, not what they've studied. But I still think its a nice intro that may make other programmers think. The article could explore open-addressing in hash-tables, and it could explore a switch statement for the vowels. Tangent: I've often wondered where the double-hashing tables are, and whether they could use the high and low bits of a single hash rather than the low bits of two hashes...?
