In short, no. Quantum computers don't really compute many things in parallel. Or rather, they do, but the problem is getting the results out. To stick with your ray tracing question, you could probably indeed trace an exponentially (in

I feel like the challenge with stuff like this is that once you edit the resulting code, the original graphical input is no longer in sync. I wish there was a good solution to this. There are many tools that come close (graphical GUI design

Can anybody explain the difference between the baseline and aligned_function cases? As the article states, they contain the exact same code, and the only difference appears to be that in one case, the function starts at C0 while in the

Actually, I'd turn this on its head and ask: Why is there this claim that they had or have any aces in the first place, Zen or no Zen? What you and the ggp are basically saying is that Intel slowed down the improvement in their proce

No. Many approximation problems are known to be NP-hard without relying on the PCP theorem. The PCP theorem is "only" one of the strongest (if not the strongest) and widely applicable result about approximation hardness. (I may

Yes, and this does indeed mean that their results may be of practical importance. At the same time, it's pretty well known that the kind of problem instances arising in practice and in those challenges are not hard instances. In other

Freedesktop.org has been doing what you're calling for for a very long time now, and with a lot of success. I remember a time when you couldn't take cut'n'paste across applications for granted... that kind of problem has

I think you may be talking past each other. It's true that investment creates jobs, but it's also true that there's no investment without consumption. The current prevailing economic policy consensus is very much misguided in

Well, they probably moved some of those funds into longer term bonds, so there could be some liquidity issues. But those would be unrelated to the price of BTC, and would be only temporary. There should never be solvency issues for a vanill

> I'm honestly not sure why you think you'd even need a GC for `hg commit --amend` or `hg rebase` (or similar operations in other VCSes). Maybe you don't call it GC, but doing a rebase in Git leaves the old, pre-rebase ver

It is supported, it's just that the only thing keeping commits not on a branch alive is the reflog. Question: How does Mercurial deal with garbage collection? After all, the desire for garbage collection is by far not unique to Git --

As a convinced Git user, this is the one aspect of the article that I found genuinely interesting. I mean, you can commit anywhere in Git, too (and I occasionally do for some advanced use cases), but it tends to not be well supported by Git

I think people generally get side-tracked by focusing too much on the staging area. It's a red herring in my opinion. I barely notice that it's there, and I do the crafting-the-public-changelog thing on an almost daily basis. I re

Git doesn't actually make people deal with staging for every commit, though. It's quite common to tell newcomers to always `git commit -a`, and `git add` for adding new files. That's pretty much exactly where SVN is/was,

While it sounds plausible on the surface, this is not at all supported empirically. There have never been economies without fractional reserve banking that one could reasonably compare with ours. There are also plausible-sounding arguments

I doubt that that's the one true answer. If I had been researching the topic at the time, I would have accepted eventual consensus. As somebody who has done research into algorithms, the reason why I would have disregarded Bitcoin&#x27

I think you're mixing up the argument of whether property is just with whether property is coercive . The arguments you've outlined are drawing a distinction between which kinds of property are thought to be just by certain s

As a counterpoint, consider that random recommendations from the internet can easily get outdated. So apparently, transparent hugepages have some issues in their current implementation that can cause big performance losses in some cases.

Yes. The "n-tetrahedron" is usually called the simplex, and the "n-octahedron" is usually called the cross-polytope.

Are miners actually selling all earned bitcoins immediately? If so, that means there must be at least 20 million USD "entering" Bitcoin every day in net terms. That seems like a lot, certainly much more than could be supported by

This "do not happen at the same time" is true in plain Xorg as well, though, since the final blit to the screen happens in the X server and not in the application. Your example of 100fps vs. 130fps on the same screen is inherently
