The fact that the search works impressed me more than anything. Of course, like every great magic trick, it seems so simple once it is explained. For the curious, here's the linked blog post describing how the project works: https://eieio.games/blog/writing-down-every-uuid/ Edit to add: I'd only tried searching for an exact UUID when I wrote this comment. I didn't realize it supports full text search! Now I'm even mo…

A great example of Teller's observation that "sometimes magic is just someone spending more time on something than anyone else might reasonably expect."

Tangentially related: HN recently (last few months) had an article explaining how large a number was. The number was something like busy beaver or 128 bit integers or something else. It illustrated how large the number was by creating activities you would do, incrementing the counter as you did them. The sequence went something like this: Walk, and every time you take a step. Add 1 After you have circled the earth, p…

The number you're thinking of is 52! (52 factorial) and how long it would take for 52! seconds to pass by.

Vsauce has a great video on this, and might be where that example was taken from.

That example starts 16 minutes into the video:

But it's worth watching the whole thing.

I'd like to announce my new `npm` package called `get-uuid`. Behind the scenes, it loads `everyuuid.com`, picks a random row number, and returns that UUID.

Awesome - this will be my new coding interview question

And then do that in parallel for 10 billion people. And for each of their devices, and servers or other supporting infrastructure. And do it multiple times per second (e.g. for every log message, every datapoint, ...)

That's why we need 128 bit numbers.

I've seen "thought experiments" (not sure they're quite that, but close enough) like that for a variety of things. The big numbers I've seen that done for most often are: unique shufflings of a deck of playing cards (about 10^68), atoms in the universe (about 10^80), and a googol (10^100). I've definitely seen the playing card one involve the walk around the world, pile of paper, grand canyon, etc (also drain the ocean a drop at a time, IIRC).

I found a good UUID but immediately lost it because the custom scroll also interprets left and right scroll :(

(this also breaks browser forward and backward trackpad gestures)
