Only 5.4 hours before you hit a UUID collision. That's insane

Either this is faked for the meme or something is very very wrong.

If this is reproducible without chicanery, I'm terrified

is this cryptomining? /s

This is the fucker who put us on the worst timeline! Get their ass!

An opportunity to share one of my favourite StackOverflow questions of all time!

It's well worth reading through the answers and the comments, but here's a little sampler platter:

This will run for a lot more than hours. Assuming it loops at 1 GHz (which it won't - it will be a lot slower than that), it will run for 10790283070806014188970 years. Which is about 83 billion times longer than the age of the universe.

damn - so maybe serveral threads generating guids is a better idea?

4 threads on a quad core processor would make it run in 20 billion times the age of the universe - so yeah, that would help a lot.

I know how I'm heating my office this winter

Please tell this is fake. I want to be ignorant about this.

i was curious how unlikely exactly this would be.

The randomUUID method generates a new version 4 UUID

which is, According to the linked documentation, a 128bit number, with some "significant bits" being changed (no idea what that's about, lets just say it's a 128bit number)

the chance of hitting a predfined number would be

1/(2^128) or 1/340282366920938463463374607431768211456

assuming your cpu does one comparison per Step at 4Ghz (4 billion per second) (idk how many steps it needs in reality, it doesn't matter, more then one tho)

that would take roughly

2.696 x 10^21 years, which is

2 x 10^11 or 200000000000 times the age of the universe

(using the expected value of geometric distribution (1/p), so 1/(1/(2^ 128)) = 2^128 steps)

I was able to reproduce this exactly.

brother you're using the wrong thing. First of all you are using crypto that's going to give you some memecoins that are obviously going to collide after 55 hours as what are you even doing not rugpulling the thing day 2?

Second of all, I am pretty sure you should use "RandomUUIDIToldYouSo" module for non-colliding hashes. We all know THAT thing gets its Noise from our parents' instructions on doing a specific thing that keep changing arbitrarily every time you ask.
