The whole idea behind this is that you'd be able to encrypt your data, upload it to your cloud provider, and use their hardware to do a bunch of work on it, without ever decrypting it. The reason why this is attractive is because you don't want your cloud provider looking at your data. If you can sort your data by plaintext, while still in ciphertext form (ie, without decrypting it on the cloud's hardware AT ALL), then what's stopping your cloud provider from doing it, too? You're leaking information about your data to your provider, and if they wanted to, they could perform a process of elimination and discover your plaintext.
Note, sorting is only ONE example of a class of algorithms that might have to be performed. Pretty much any useful algorithm would in some way leak information about the plaintext, in a way that would be visible to people who don't have your private key. That defeats the whole purpose. Might as well just upload all your data XOR encrypted.
The thing to keep in mind here is that the idea is to make it so your cloud provider has no way to read, or infer information about, your data. I'm in the camp that believes it's not possible, but even if it is possible, known methods (like this one) are neither plausible nor secure.
No. You're not capturing the magnitude of how few operations we have at our disposal with FHE. We can add, and we can multiply, and we can compare ciphertexts. Those are the three basic operations you can perform. Even if you could somehow divine the proper sorting of plaintexts, based upon their ciphertexts (And I'm even ignoring the fact that that would leak information like a sieve, for now), you'd have to go through god knows how many hundreds of add/multiply/compare iterations to do it. It's just not feasible.
Now, to address that little point I said I was ignoring. If you can discern ANYTHING about the plaintext from the ciphertext, it means your encryption is leaking. However, in order to do anything useful with cloud computation, you HAVE to be able to know about the ciphertext. How many "cloud" operations do you have at your workplace where you process data blindly adding and multiplying? Imagine an actuarial scenario: You've got a bunch of (encrypted) policy data that you've uploaded to the cloud for rating. The premium rate for a policy depends on dozens or hundreds of variables. Everything from where you live to whether your car has power windows. Without being able to discern that information from the ciphertext, you can't properly rate the policy. But if you can discern the information, you've defeated the entire purpose of your encryption.
It's neat math, but I don't see how it can be used to do anything useful, while still protecting your data.
So, I've got this encrypted data, and I can do these operations to it and it'll still be encrypted blah blah blah. I want to alphabetically sort some data. If I'm reading this right, you're screwed. Not seeing the utility, if that's the case.
You are searching the Internet. I'm not sure what context is lost by using the search box instead of navigating to google.com. I can understand your point about the Windows search, but the Internet doesn't have subdirectories, and you don't have a working folder in it.
From what I've seen of the KDE devs, you'd be exactly wrong on that front. New features are always prioritized because they're exciting, while bugfixes get ignored. I don't have the link handy, but awhile back I saw a bug report regarding (iirc) icon opacity, that had stagnated for years. From everything I've seen, the devs aren't as interested in making sure everything works flawlessly as they are in being progressive.
Doesn't dark matter have to interact via gravity in order to be responsible for the things it's claimed to be responsible for? If that's the case, why didn't it react with anything? It's not as though the regular matter was interacting through electromagnetic, weak, or strong forces in any significant way during the collision. Gravity should have effected both types of matter equally, shouldn't it?

Well shit, even the book industry is laughing at the music industry now.
In fact, from what I've heard from a buddy who used to work at apple, it's not uncommon for them to do custom designs (by which I mean minor adjustments, not wholescale redesigns) for their chips. They don't manufacture them, certainly, but they're not just shipping devices with bog-standard chips they got from sparkfun.
So, we think the bird went extinct 40k years ago, so we're using that to date the painting as being that old? Does that seem backwards to anyone else? How about we date the painting, then maybe we can get a better estimate of exactly when these birds went extinct?
The thing people don't like is that Apple doesn't give you the choice. Sure, you're the protecting father who doesn't want little Sally installing viruses on her sparkly new iPad. That's great. They should give you parental controls. Those parental controls should be able to be disabled so sleezy Sam can browse all the dark corners of the internet, install all his dubious apps, and play porn games on his iPad.
People don't mind being ABLE to restrict the content that reaches them. They mind when it's some corporation halfway across the USA pushing their social agenda on them*.

Fortunately for the government, the people of our country have the attention span of a goldfish. Weeks will go by, everyone will forget about this just like they've forgotten about everything else, and the government will hand out a barely-publicized slap on the wrist.
The summary tries to drum up angst about the title of the bill, but when you think about it for a couple seconds, it becomes evident that it's actually just the most honest bill title you'll ever see. I'm not saying anything about whether their "reasonable and justifiable" limitations are reasonable and justifiable in my opinion. Clearly they are in their opinion however, and they have entitled their bill thusly. Here in the USA, if this same bill was attempted, it'd probably have a cryptic title with lots of numbers in it that don't tell you anything about what it does/says/means. At least this bill TELLS you that it's fucking with your freedoms.
So Bravo, I say, to whoever penned the title to this bill. Good to see a government not hiding behind the curtains of obfuscation.
PS: Let's not forget that there're more than a couple bills in whatever land you're hailing from that likely could be titled similarly, because when it gets right down to it, some limitation of "freedom of expression" is needed. We just tend to call them murder laws instead, but there's no reason why they have to be called that.
Because perhaps the reproduction genes of other viruses don't function in the same fashion, and thus cannot be attacked in this way? That's what comes to mind first.
Centralized communications base, perhaps? Rather than beaming commands to a bunch of scattered robots, they beam to the stationary comm base, which then can use other (perhaps more suitable/robust) transmission protocols/wavelengths to the robots.
I think you're just smelling progress in other parts of the world. We here in the USA have too many other things going on to be worrying about a space race right now. It's not on the forefront of the mind of anyone who matters.

Doesn't matter what we call the two things. We just know that in this case, one requires the other.
So that's why fat people live shorter lives! Time really just moves faster for them, because they have more mass!
Additionally, I'd be willing to bet more people regard their music as indispensible than their ebooks.

If statistics tell us that the modern generation does more for its neighbour, then it is more empathetic for any practical meaning of the term.
Either that or more kids are trying to get laid with the girl next door.

Sure, but they don't have any real power to do anything about it. As long as the majority forgets, that's all the government needs.
