Re: Every V4 UUID
#102Sometimes I feel bad when I generate a UUID without using it for anything. Like I've wasted it.
There's enough of them that you're saving a scarcer resource by not recording it anywhere.

#103Very useful! I'll refer to it when I forget my UUIDs, I use this site all the time to remember my bitcoin private key [0] [0]: https://privatekeys.pw/keys/bitcoin/1
Thanks for this, I didn't know that people create weak BTC keys for fun. I guess some are also used as bot honeypots?
Back in the day people used to SHA256 a passphrase and create a Bitcoin private key from it.

#104The 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…
Yeah, I at first, I though I knew exactly how it worked. Then I saw the search field, and I suddenly had no idea what the hell was going on. Now, the big question, do I want to spoil the magic trick and read how this was done, or should I keep being astonished and flabbergasted?
I disagree with my sibling comment. The trick is beautiful. If you generate UUIDs such that each bit in the result can be reliably traced back to a single bit in the input, then you can take a substring of the UUID and use that to infer which bits of the input integer must be set to produce that substring. So you can produce a whole list of input bytes that meet the criteria and those become your search results.
The real magic trick here is that the uuids on the page only look random to us because of some bit twiddling and XOR trickery. If we had a better intuition for such things we would notice that successive UUIDs are just as correlated as successive integers.
Elegant stuff

The explanation for full-text search was actually slightly more intelligent than what I initially assumed. I figured it just generated UUIDs until it found one that was in the correct direction of search (for the next/previous button), since I had observed that walking forwards and backwards in search results was giving different results each time, but in fact the author did the slightly better thing which is to just generate a bunch of possible results and then pick the best (I wonder how many results it generates for this?).

#106Compression is now so advanced, we can browse web pages weighing over 340 undecillion bytes. We truly live in an age of wonders.
Meh. Years ago I had my bakeries churning out undecillions of units no problem in Cookie Clicker. No big deal!
They just don't make em like they used to...

#107This is amazing! I can finally get that vanity UUID I was dreaming of for so long!

Re: Every V4 UUID
#110I’m writing a script that scrolls through the site, scrapes the UUIDs, and stores them in an AWS S3 bucket. I’ll let you know when it finishes.
Something tells me S3 was not designed for that and will break, and then everything will break.
And because StackOverflow broke too, there's nobody available to fix it.
