Yeah, NSA advised that DES keys should only be 56 bits (or fewer). That was/great/ advice given that extrapolating the final crack-box's cost backwards in time we can see that the NSA would have had the budget to brute-force crack such keys at least a decade before the public crack.
You can transform a factoring problem into a SAT problem. That doesn't mean that factoring has the same complexity class as SAT, only that it's no more than that of SAT. Polynomially transforming arbitrary SAT into FACTORS would be a different matter entirely.
I don't believe anyone would put any money on FACTORS being NP-complete.
It's an problem for which there are well-known sub-exponential algorithms, for example, whereas there are many NP problems for which there are no sub-exponential solutions. Of all NP problems, perhaps FACTORS is one of the "easiest", in fact.
The problem was with the plan, and the plan should have been fixed way back. Just continuing to disregard the plan and not deliver on time is irresponsible. Irresponsible workers are a liability. That's you, that is.
Anything with plausible deniability as a feature, as a consequence, cannot have plausible deniability as a feature. I can't believe people are so dumb that they can't work that out.
How do you 'see' a false positive? If it is positive, it's binned? Are you saying that you have to go checking through the bins just in case it dumped a real mail there?
Nonsense. Much of the spam I get in my yahoomail inbox is from Domain Keys verified senders. And I can't block that particular sender, as it's yahoo.com itself, from which a fair proportion of my real mail comes.
OK, not sign language - but how about semaphore communication?
I suspect it will just be some horrible bastardisation of saturday night fever rather than anything practically useful. But why should entertainment be practically useful? It's exercise, it probably hones reactions and coordination, and it can also be competitive to whatever level people want to take it, which seems to increase how much it will hook young'uns (males, usually). Better than the (indoor) equivalents from my youth, certainly.
And yet they offer 4.18KB, 2.88KB, 2.64KB and 1.38KB images with every page. That's 3 unecessary transactions, which is worse than just the sum of its parts.
The itanium is the ultimate batch processing box. Task switches are expensive with that great fat register set, so you just want to let it work on one thing at a time.
Superb for numerics, as you can hide all the latencies by using enough parallelism.
One where the compiler will save you a lot of hassle, but probably not be totally optimal as there are too many possibilities for it to investigate.
I'd certainly like to play with one. My bet is that a well-tuned FFT could be blisteringly fast.
Signing is irrelevant if the hackers can simply reproduce MS's process of signing. If they have hypothetically ownz0red MS's machines, there's no way of knowing if that signing process hasn't also been hijacked.
That's the commonly held belief, but when my machine was rooted 5 years back (after two zillion and one attacks, I live on a very busy IP block), I took a different approach. I shutdown, booted from CD and compared fingerprints of all files in the root filesystem with ones backed up only a now read-only floppy. I then manually replaced all the files that had been modified by the rootkit. It was about 2 hours work. A reinstall of the full system would have been much longer. It wasn't a very intrusive rootkit, it didn't modify the zImage for example, and I may have opted for a full reinstall if it had put its claws in too many critical files.
However, if you don't know 100% what you're doing, you should just assume that everything is compromised until proved otherwise, and a full reinstall is the best way to be sure.
To be sure of being susceptible to rooting by exactly the same exploit again, alas.
Possibly quite a long time. Destructive viruses are now no longer fashionable. You lose your little helper if you kill it - much better to keep it alive.
There is pretty much no way of using DRM without it being misuse. DRM removes freedoms which have been purposely and purposefully granted (fair use, etc.) ever since intellectual property laws were first written down.
Not hugely, perhaps 0.3%, but it was consistently faster for what I was doing. I put it down simply to having a better scheduler, and less cache trashing on task switches, or some other voodoo like that.
So such paradoxes are far from unusual.
Of course, we could combine these two improvements...

He didn't want everything to be a hyperlink, but that was the only way that he could get it to work using CSS. In which case, he's using a technique of asking for something that you don't want to get what you want done. This is a bad design.
So 5/10 for effort, but 0/10 for being a useful technique for a portably viewable web.
What could be possible on the command line that isn't currently? You'd have to get into some pretty contrived piping examples I'm sure, and how many people actually want to do such things? Even then, the pipe shell should be your shell of choice rather than bash. I think we're all agreed that csh and tcsh are broken, but bash and a few others are pretty powerful.
Yes. Just make sure you have the required libraries. A decent package management system, such as dpkg, will ensure this is the case. I run neither Gnome nor KDE as my environment, but can run binaries designed for both.
The (D)FT is a function. A vector of sums of products of elements of another vector. That, in itself, defines an algorithm. In some languages, the expression of the function itself is exactly the same as the expression of the algorithm. (Mathematica, GP/Pari, and presumably Maple, et al.)
I've already implied that what matters to you is of no consequence to anyone with any sense. Quite why you decide to then bring it up is further demonstration of your cognitive inabilities.

In the same way that all RISCs are the same.
