Number #553752677 will surprise you!

It's actually number #5316911983139663491615228241121378304 if you were keeping count.

PINs can be up to 6 digits (at least here in the UK, but I doubt it's country specific), even though the ones they give you by default are only ever 4. So that's only a leak of 1% of them.

My card doesn't even let me include repeating digits in its PIN. I suppose it can make a one-off guess more likely than one in a thousand to correctly guess my PIN.

Which is honestly not a bad idea, given that somebody shoulder surfing or trying to read smudges on the PIN pad becomes much easier in the case of repeated numbers.

"1111" would just leave a fingerprint on a single key, for example, and only one possible PIN (or maybe 3, if the bank/card allows 6 digit PINs).

Would love it if the scrollbar was draggable on iOS! I thought it was broken until I realized you can click on a spot to scroll to.

My favorite of these was a trick where someone picked a card out of a deck and then Teller revealed a large version of that same card in an unexpected area in the vicinity, It turns out that what he had done was hide a complete set of large cards in the area before the trick and memorized the location of every one of them so, e.g., the king of hearts would be at the top of a palm tree, the three of spades under a dri…

The best part is that that kind of trick usually becomes more, rather than less, impressive when its inner working is revealed. I recently got to see them perform live, and my favorite trick by far was one of that kind.

Watching Teller do the cups and balls trick with transparent cups is mesmerizing.

Yes, you can see everything. No, you still can't follow it.

Sure, you can see that "something changed" after the fact when it is stable. However, Teller is so damn smooth and fast that any active change looks like teleportation.

Compression is now so advanced, we can browse web pages weighing over 340 undecillion bytes. We truly live in an age of wonders.

I am pretty sure this sets a new record for highest Weissman score

Weissman score doesn't really have meaning anymore if the input is constrained. For example this website is 200KB as per the network traffic and I can beat it handily with ten-line script to generate every UUID. Or even verbally by just saying "every UUID".

Seems like some hacker leaked all UUIDs. Check if your UUIDs are part of the leak.

Nerd hacker politics, but SSN leaks are no joke.

Agreed: The real joke is any organization using SSNs as an authentication mechanism (as opposed to an identifier).

I tried to find the biggest UUID and if I got it right, it's 99999999-9999-4999-9999-999999999999 (note the 4 in the 3rd block) I'm curious why it's not 99999999-9999-9999-9999-999999999999 (all 9s)?

It depend on the UUID version you're using. Version 4 (Random) will always have that value be 4 as per RFC 9562. So 99999999-9999-9999-9999-999999999999 is a valid UUID but not a valid UUID v4. If you wanted to be pedantic the website should have been named https://everyuuidv4.com/ https://datatracker.ietf.org/doc/html/rfc9562

The last line of https://xkcd.com/566/, except it's UUID formats.

Very 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?

Definitely! Takes a bit of time to go through all of them, though.

I think this is a joke, but I think it is a problem if someone finds any sensitive uuid here, because the list on this website is a tiny subset of all possible uuids, so it provides a useful rainbow table for anyone attempting brute force attacks. I.e. generating and using random uuids would have an astronomically small success rate, whereas trying the ones on this site may not (depending on where they came from, whi…

You should check out the author's blog post about the site — it is quite literally every UUID, computed and rendered on demand. https://eieio.games/blog/writing-down-every-uuid/

Oh.. ha, gotcha. Thanks for explaining. Incidentally, glad uuid's computed on the fly (as opposed to pre-computed) as I think the site would require a very (impossibly?) large database.

They're coming straight out of your processor :)

Careful where you scroll: Your password and your crypto wallet recovery phrase are in there somewhere too! (Unless you have one of those fancy 24 word long ones.)
