hikari-no-yume / CUAD.hs
Created Oct 26, 2016
CUADs are an alternative to UUIDs I created for a project which didn't get finished
View CUAD.hs
-- UUIDs are terrible, and I couldn't get the `uuid` package to work on Haste
-- So here's something similar that I like more
-- CUAD: Cute, Unique And iDentifying
-- (new backronym thanks to those lovely three Irenes)
-- A quad (see what I did there?) of four 32-bit words
-- Canon text representation is 4 hex words separated by dashes
-- e.g. 01234567-89abcdef-deadbeef-abad1dea
-- Like UUIDv4, these should be random (probabilistically unique)
-- Unlike UUIDv4, these have 2^6x as much randomness (128 bits, not 122)
