Comment Proof of cutoff point (Score 1) 143

One could image the editors being just a little bit 'happier' with the proof if just a bit more information was provided about the number 7825.

Correct me if I'm wrong, but 7825 has to be part of at least one Pythagorean Triple, no? If you take all the integers up to 7824 and you can divide them up, but then you fail when you add 7825, then 7825 has to be part of a triple, otherwise it wouldn't be a tipping point.

So there has to be at least one set of numbers a and b such that a + b = 7825. a and b must be smaller than 7825 which is why 7825 has to be the c in the Pythagorean theorem.

So if any such numbers a and b could be given as additional information, the reason for 7825 would be clearer.

Like if you're dividing red and blue marbles over 2 containers and you can't have two of the same color in a container. You can divide 4 of them, 1 of each color in each container, but when you try to place a fifth, all containers are full.

Here, same thing: when you reach 7825, all the containers are full and you can't squeeze in an extra triple anywhere.

Have you ever read what happened in Yellowstone when the wolves were reintroduced?


Now, okay, the wolf is an apex predator who has a much bigger effect on the ecosystem than a pigeon. But I believe this is one of the best examples you can give that putting species back where they've gone extinct can have some very beneficial effects.

We have managed to establish a basic form of communication with some chimpanzees, well within human liftetimes, because they are able to see us (visual sensors in the right frequancy band) and they are able to make delicate motions that we can see.

If we make contact with aliens of approximately that level of sophistication, we should be fine.

Add to that the possibility of them hearing us (again, sensors in the right range) and hopefully vice-versa, and we should not have too much problems that cannot be overcome.

Comment Re:Support for NFC payments ? In the kernel ?? (Score 5, Informative) 141

From TFA:

"This release implements support for the Secure Element. A netlink API is available to enable, disable and discover NFC attached (embedded or UICC ones) secure elements. With some userspace help, this allows to support NFC payments, used to implement financial transactions. Only the pn544 driver currently supports this API."

In other words, the kernel now contains the necessary API so the PC can correctly talk to a NFC Secure Element which is needed to be able to make payments over NFC, in tandem with userspace tools.

So yeah, the label is a bit misleading...
