That is kind of misleading statement. What quantum computers change is not how many operations per second you could do, but how many operations you need to factor large numbers. I believe that Bremermann's limit should also apply to qu

Well sure, but there is a much more direct refutation of the claim that no physical system can achieve human level intelligence: humans exist.

Not really. If we are inside a simulation running on some CPU in the "real world" and they move the simulation to a CPU that's half as slow, from our point of view nothing changes. From the point of view of whoever is running

That is pretty amazing, you should definitely advertise it!

Well, in this case T-Mobile is not modifying your packets, they are just slowing them down, so maybe they would still qualify?

The practice the author was referring too, paying indulgences is (thankfully) not a "widely practiced religious act".

Well, we have found all the particles predicted by the Standard Model, last one missing was the Higgs boson. However, no-one really believes that the Standard Model is the ultimate theory. There must be other stuff out there that we have fo

Yes, I'd seen that white paper, and thought static_if would never happen in C++. Concepts are nice for some things, but as Alexandrescu argues convincingly in the talk omaranto linked, they become quickly become very unwieldy if you ne

Yes, that was it. Thanks for finding it.

Really cool talk on an implementation of static_if in C++14. I'd suspected something like it should be possible, but couldn't get it to work right. Great to have someone figure it out for me :). Also, cool to see that they are con

It's easy to feel outraged, but you'd be just playing Trump's game. Does he believe there is a chance that the US will actually ban Muslims from entering the country? Or even that it would be a good thing if it did? No, he ju

Well, Lebesgue integration cannot handle delta functions either since they are not even functions but distributions. (Incidentally, there is such a thing as Lebesgue-Stieltjes integral, the kind of issues Riemann-Stieltjes solve are orthogo

For applications in physics and other sciences the Lebesgue integral is not critical. Even if you care about making sure your calculations are mathematically sound then the theory of the Riemann integral (much older than Lebesgue's) is

I believe gp meant Javascript's "use strict" equivalent in C++, which I would say is comparable to the compiler flags.

It is not. $e_r$ is a rotating vector, not constant. Also $r$ is not really constant either. Actually, if you think about it, the only plausible way you could have something in space with zero jerk and non-zero acceleration would be an inte

Even without any encryption, a perfectly compressed signal will be indistinguishable from random noise. Of course, it might still be distinguishably artificial depending on how it is encoded, but I believe that the SETI searches that have b

You make an argument that I think a lot of people make implicitly and that I think is worth refuting. The argument is this: "The fact that HFT firms make money 300+ days in a row, means they are not really running any risk (and probabl

I am happy to discuss these issues, but would rather have a fact based discussion than resort to insults. Firstly, not sure what you think the distinction is between HFTs as opposed and "algorithimic market makers". I think most p

This is an often repeated claim, but things do not become true by repetition. First of all, HFTs have certainly taken over market making functions in today's markets, almost entirely in equities, to a lesser extent in some other asset

Not that I hold it against him, but José Saramago was a white guy (although he was pretty tan). It is a pretty great book.
