Here's the correct way to pronounce some tech-related jargon:
char => Pronounced as "car".
enum => Pronounced as "e-num". Rhymes with thumb.
GIF => Pronounced with a soft "g". Rhymes with Jif.
GUID => Pronounced as "goo-id".
SQL => Pronounced as the word "sequel".
UUID => Pronounced as "you-id".
There's definitely no other way to pronounce these.
