This comment is in the library of babel.

How many bytes is the Library of Babel?

Petabytes? Exabytes? Zettabytes?

The specifications described in Borges' original short story implies there are 25^1312000 books, which is unfathomably large but technically still finite.

[–] threelonmusketeers@sh.itjust.works 2 points 11 months ago (1 children)

If it's stored on a server somewhere, it can't be infinite.

[–] Irelephant@lemm.ee 16 points 11 months ago (1 children)

Its generated dynamically based on a seed string.

[–] threelonmusketeers@sh.itjust.works -1 points 11 months ago (1 children)

Huh, if it's dynamically generated, would the storage required to host website grow as visitors search for more strings?

[–] bane_killgrind@slrpnk.net 5 points 11 months ago (1 children)

It doesn't generate and save it, it generates it again at the same position.

[–] threelonmusketeers@sh.itjust.works 1 points 11 months ago (3 children)

In that case, wouldn't the "address" for the position of the string in the library be as long as the string itself?

[–] Redjard@lemmy.dbzer0.com 3 points 11 months ago

Yes, it's a fancy way to turn a link containing encoded text into that text.

This is a link to a book. Its much larger than the url, thats just the seed to generate it.

[–] filcuk@lemmy.zip 2 points 11 months ago* (last edited 11 months ago)

Address is the seed. It's not stored. Try visiting it to see how it works.

[–] dreadbeef@lemmy.dbzer0.com 26 points 11 months ago

Every v4 UUID 🤭 /snark

[–] tauren@lemm.ee 15 points 11 months ago

Thank God, found mine.

[–] heavy@sh.itjust.works 13 points 11 months ago

Finally, a useful website

[–] homesweethomeMrL@lemmy.world 5 points 11 months ago (1 children)

My son is also named Bort.

[–] nightwatch_admin@feddit.nl 3 points 11 months ago (1 children)

Bort..as? Orville vibes, sorry.

my Minecraft uuid isn't in here :(

[–] Irelephant@lemm.ee 1 points 11 months ago

is it a v4? The search thing is a bit wonky.

[–] sik0fewl@lemmy.ca 4 points 11 months ago

It would be nice if they were sorted.

[–] Hairyfishnuts@sh.itjust.works 4 points 11 months ago (1 children)

Splain Lucy. What's the use case for these, please? Tried looking it up myself but still not sure. Thanks in advance.

[–] Irelephant@lemm.ee 4 points 11 months ago (1 children)

A uuid is something that can be used as an id (identifier). It stands for Univerally Unique Identifier. This has a list of all of them, because it generates every valid one.

[–] Hairyfishnuts@sh.itjust.works 5 points 11 months ago (3 children)

I did learn what it stood for in my travels. I wish to know the use cases for such things. Eli5 if posssible, please.

[–] StaticFlow@feddit.uk 6 points 11 months ago

In applications it was very common to use an auto incrementing number for id's. So one account would have id of one, then the next two, etc... This can cause problems if there is an unautheticated api endpoint which returns user info given an ID value, someone could just put in all the Id's counting up from one to find out all the records in the database. UUID's are a way of obscuring that, making it pretty hard to enumerate all records if they cant count up in an orderly fashion. It's also useful in distributed systems, the many instances of a running service could generate an ID value on each server instance before recording the value in the the database, there is a low chance of ID collisions.

[–] letsgo@lemm.ee 3 points 11 months ago

One use is in URL identifiers. If my account number is 47, for example, I could reasonably guess that accounts 1-46 exist and potentially look at other customers' data.

But if it uses a UUID instead then it's a lot harder to do that.

[–] Irelephant@lemm.ee 3 points 11 months ago

They are used as ids, like a post id or a user id in technology.

[–] bane_killgrind@slrpnk.net 2 points 11 months ago

The video the guy did about making this was great
