      crypto - as in cryptography, not cryptocurrency - is just the library he’s using to generate the 128-bit random UUID. The snippet is interesting because he matched the original UUID in just over 5 hours. You’d expect to need more than 10^38 guesses to pick the same number again, which, even at 1 guess every microsecond, means something like 10^22 years.

        Sorry, I forgot to add the /s.

        But thank you for the calculations, it’s actually interesting :) I was thinking about that myself, but didn’t bother to do the math.

        I thought its reminiscent of cryptomining as it also consist of guessing an arbitrary number just for fun.

          Internet sarcasm is hard, and lemmy has a very general audience :) I’m always happy when someone gives me an excuse to do the math I was already curious about - it’s often not worth it, for just my own curiosity, but even a sarcastic or disingenuous prompt reminds me that there’s other casually curious people out there.

        I wanted to downvote you for failing to pick up on the sarcasm, but then you went and did all that math that I was too lazy to do and I ended up upvoting you instead. Damn you!
