I'm using 16b55183-1697-496e-bc8a-854eb9aae0f3 and probably some more too. I suppose if we all post our list here, then we can all check for duplicates?

You can check https://everyuuid.com/ for collisions.

We should all send our already-generated UUIDs to a shared database, we could just put it on Supabase with a shared username/password posted on HN, so we can all ensure that after generating a UUIDv4 locally, it's not used by anyone else. If it's in the database, we know it's taken.

It's a super simple mechanism, check in common worldwide UUID database, if not in there, you can use it. Perhaps if we use a START TRANSACTION, we could ensure it's not taken as we insert. But that's all easy, I'll ask Claude to wire it up, no problem.

		But then I will claim I have already used all the UUIDs in my spreadsheets, and my lawyer will send cease&desist letters to every database.
