What the hell are the controls? I can't figure out how to swing the sword.

No. If you have a good hash function, that means it's computationally infeasible to determine anything about x based only on y. It's not statistically impossible at all; "statistically" doesn't concern itself

"Amplitudes" here refers to the thing that QM uses instead of probabilities, not any other sort of amplitude.

You're off by at least an order of magnitude there; we have DNA samples from well further back than that, such as from Neanderthals and from mammoths. But no, it doesn't last long enough to get DNA samples from dinosaurs. I don&#

"Quantum theory based on real numbers" means a specific thing -- quantum mechanics with real amplitudes (and real anything-else-that-would-follow-from-that). It doesn't mean just any way of representing quantum mechanics wit

Yes, but it's not the word's primary meaning. Using it in a headline like that -- where it's the first thing the reader sees, rather than after context has been established -- is misleading.

Note that the Wald story may not have actually happened: http://www.ams.org/publicoutreach/feature-column/fc-2016-06 (But yes, Abraham Wald is the statistician that the story is about.)

The problem described isn't a metaphor or a proxy; it's not about some other thing like mutual information. It's about exactly what it says it is: evenly-spaced (arithmetic) subsequences. More formally, given k, you have the

I would normally assume "sanitization" means "escaping"... as far as I'm concerned, anything other than escaping is incorrect sanitization!

I mean, of course it is, it's just saving the PNG; it's not going to decode it and then re-encode it or something!

Coding is basically just ifs and while loops.

I see, thanks!

My understanding was that one was originally the expected NSFW thing, then got taken over and turned into what it is now. I can't find an easy way to confirm or refute this at the moment, though, so this may be mistaken.

It's not pointless, it's just on a different topic. It's about who first suggested the idea. It's only "frustrating and pointless" if you thought the article was about the the truth or falsity of the idea, ra

It discusses who first suggested the idea; why is that not worth reading? That's certainly not just an ad for a book.

by Sniffnoy 5y ago
No, because it discusses who first suggested the idea. I'd say that's interesting whether the claim is true or false. It's not pointless just because it's not on the topic you thought it was on.

The article explicitly states that it is not going to present the evidence against the myth; it isn't trying to demonstrate that the myth is false, it's leaving that for elsewhere.

That doesn't go against the point of this article, it enhances it. Teams mattering reduces the fungibility of people even further .

So how much of the search space does this leave? Batygin and Brown recently did a search of existing data for Planet Nine and didn't find it, but they also put up this nice diagram[1] of just how much of the search space this rules ou

Heh, kind of like dynamic scoping, except as applied to control flow...

No, that's almost certainly not related. The relative volumes of the cube and the sphere is a geometric matter, not a topological one. Remember that topology uses much looser equivalences that do not respect such information.

by Sniffnoy 5y ago
Not a topologist, but my understanding is that high dimensions can be handled by one set of methods because there's so much freedom, while low dimensions can be handled by another set of methods because they're so constrained. An

The reason why is that Unicode was originally 16-bit, and there was no way they could fit everything into 16 bits without CJK unification. Of course later it turned out there was no way they could fit everything into 16 bits anyway, and so
