Please, do not use b6133fd6-70fe-4fe3-bed6-8ca8fc9386cd, I checked my database and I was using it already.

I knew it, we're all getting the same cheap UUIDs and the good ones are reserved for the big dogs.

		uuid.uuidv4() recently switched to "adaptive entropy" instead of "xmax entropy" in an effort to save costs on non-premium users.

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.

That UUID should have my name sticker on it. Don't your UUIDs have name stickers?
