There is an IETF standard for UUIDs? Do we need an IETF standard for UUIDs? I've been coding since the '90s and never thought a UUID to be complicated or contentious enough to need a standard. I guess it makes for a pretty unique icebreaker to say you've contributed to an IETF standard, if you get invited to those sort of parties.

If you're generating UUIDs from different languages, libraries, etc. you want to be sure there doing it the same way.

My face, screaming in horror, but in words instead. I've only really worked with projects in homogenous languages on the application side, so hadn't considered that. Thanks for taking the time to reply.

Look the issues with java.util.UUID and Postgres.
