  1. Re:Sounds impractical on IBM Researchers Open Source Homomorphic Crypto Library · · Score: 3, Interesting

    The summary doesn't really explain this that well... the benefits here (if I'm reading this correctly) are that someone with a HUGE block of ciphertext and the encryption key can modify slices in situ without having to decrypt the large block and re-encrypt. They can just swap out the old data for the new, based on the index.

    This begins to have significant benefits when applied to hosted computing (called Cloud Computing this decade), where, say, all your email is stored encrypted, as is the email index, and you just want to add/remove something without decrypting the entire blob. It also means that cloud hashing becomes significantly easier, as does filesystem-level encryption (since we no longer need to depend on block ciphers, but can use a homomorphic stream cipher and then chop it up after the fact).

    Err, no, you are actually reading it completely wrong.

    The point is actually that you can give encrypted data, say, some of your company's vital statistics, to an outsider (for example, a consulting agency); that agency can do a computation on that encrypted data (say, their super-secret algorithm that analyzes your company and tells you how to get rich fast) and get an encrypted result, which it then gives back to you. Only you can then decrypt the result.

    You get to keep your data secret, and the company doing the computation gets to keep the function they compute secret; the only thing revealed to you is the function applied to your data, and nothing is revealed to the consulting agency.

    The big stumbling block to this point has been that the speed gains achieved by homomorphism have been offset by the overhead in implementing the homomorphic algorithms in the first place -- meaning that it's faster to decrypt, modify, re-encrypt.

    Homomorphic encryption most certainly is not about speed gains.

    That's just bullshit. A Linux distro is the party that provides the software to you. It's not "third party software". You report bugs to the distribution. You get updates from the distribution. The distribution does the stabilization and integration work to make everything work smoothly with all the other packages in the system. Granted, most of the packages have upstreams, but that doesn't make it "third party" software. The distribution is the gatekeeper. They make all the decisions on what the users get and what they don't. They configure, build and package the software. They often make significant changes to the software, for example keeping track of security bugs and backporting fixes to their stable releases. The upstreams cannot push upgrades (or malware) to users, but have to go through the distribution.

    And if things break, if you get malware in a package, the distribution is the party that loses its reputation. They have a reputation to protect, unlike many third parties, which might want to get some extra revenue from people who click on ads to "optimize their IP address" or some such crap. That's why the packages from a distribution won't come with IE toolbars that are installed along with the package.

    The distribution idea, to make a centralized party to act as a gatekeeper and to take the third parties out of the equation for a normal user, is the revolutionary idea that ensures a well-working ecosystem.

    It's nowhere near as confused as the ruling by a UK top court a few years ago about software patents.

The UK court ruled that algorithms are not patentable, unless the algorithm in question has an effect on the computer that makes it "a better computer", such as by "making more memory available for programs" or "making it run faster". Now I'm actually convinced that it wasn't a desperate decision by the court in order to keep software patents either: UK's response to an European Patent Office questionnaire about whether algorithms should be patentable largely repeated the conclusions of the court, and it's hard to say that it was a pro-SWPAT stance, although it certainly wasn't an anti-SWPAT stance. It was plainly and simply a confused stance which did not make any sense at all.

Plainly, that's not what copyright is for, and the courts don't usually sanction trying to use it for that. One factor against copyright in this particular case is that the message was highly fact (or allegation) rich and not some elaborate prose warranting copyright protection.

    No, they haven't. This has nothing to do with where the product was manufactured and everything to do with where it was first sold to the public. Therefore, once the product (the individual watch in this case) was first sold in the US with the permission of the rights holder, after that they can no longer control further sales. In this case the watch was never sold in the US with the rights holder's permission, so the first sale doctrine does not apply in the US.

    All this applies regardless of where the watch was actually manufactured. It might have been manufactured in the US but never sold in the US with permission, and the situation would have been the same. So essentially it's not about first sale; it's about first sale in the US.

    Interesting post. I usually try to stay out of the religious discussion on slashdot, because, really, it's full of people who have heard some arguments against Bible and think they are experts on the subject even without having ever read it. Invariably none of them have heard of the rather clear distinction between moral law (that is supposed to be eternal) and the ritual law that forbade the Israeli from e.g. mixing separate materials in clothing in some ways, to remind them of their covenant with God - which the New Testament has made abundantly clear is not God's current covenant with people (there's a reason it's called the Old Covenant). But no, bashing the Bible with poor reasoning appears to be so fun that anyone should do it, regardless of whether they've ever read it. Come on, people, you can find better arguments against the Bible, they certainly do exist, and you can figure them out. Of course that might require, heavens forbid, actually researching stuff instead of just blindly bashing and repeating arguments invented by equally ignorant people.

    But I'm not blaming you for all that. I get the feeling your post contains kind of authentic puzzlement about the behavior of us Christians. That's good. I think it deserves an answer. I'll do my best to explain in the hope that you find some kind of answer to your puzzlement in my words.

    What you are wondering about is one quality that I believe truly sets Christianity apart from other monotheistic religions. What you describe is, I believe, actually quite close to Islam (and I'd say that Islam and Judaism are much closer to each other than either to Christianity). Islam teaches us thus, simplifying things a bit: If you can believe in God (Allah), that's undoubtedly good; but even if you can't, the most important thing is that you submit. The literal translation of the word "islam" is "submission" (and "muslim" = "one who submits"). This is reflected in popular muslim names like Abdullah, "slave of Allah".

    The relationship of God to people, as reflected in the Old Testament, is somewhat like that, but my feeling is that it's not that strict in a sense. The emphasis, in any case, is on good deeds, and to an extent obeyance. Somewhat in contrast to Islam, the Old Testament still talks about God adopting Israel as its people, and giving them his good law because he knows, like a father setting limits to his daughter, that it's good to the people. Even in the OT, it's more of a parent-child relationship than master-slave. In the Old Testament, the child is the people of Israel.

    In the New Testament, the death of Jesus changes things materially. It begins a New Covenant, replacing the old one that the people of Israel had broken so many times anyway. The death of Jesus provides a complete atonement of the sin of mankind. The Bible literally promises that to those who believe, all their sins are forgiven because of the blood of Jesus. In fact, this is a core tenet of Christianity: That every person, no matter how Christian, is a sinner, and repeatedly commits sin; that nothing they do themselves can redeem themselves. However the Bible also promises that we can leave all our sins to Jesus, and he will wash them away. It's not a matter of ego, as you say:

    Either these people don't really believe, or they believe but they think their god is lying about the whole eternity bit, or their own ego is so great that they just think god'll forgive them all their transgressions

    Indeed, it's hard to believe that God forgives all our transgressions, but that's what the Bible says about the matter. It also says that if the death of Jesus did not atone some of our sins, there would be no way to heaven for any of us. Yes, to a Christian life is a journey towards life less controlled by sin, but nobody will become so good that he would not need God to wash away his sins. This may seem like excusing doing anything at all, because we know we will be forgiven. That's half true - we know we will be fo

They demonstrate quite nicely that enforcing a foreign judgment of a foreign state with which there is no treaty is nowhere near that automatic you claim. In each of the cases in that document, the claims that the party had requisite contacts were quite a bit stronger than in e360. In each of those cases there was a judgment in US court. And in each of those cases, the UK court refused to enforce.

    There even was a case (US v. Inkley) where the US government seeked to enforce a default monetary judgment in a fraud case, where the defendant had been present and arrested in Florida, but the US government had stupidly let him leave the country. The judgment obtained was not enforceable in UK. How do you explain that if you think it's so automatic?

    (Note that inside the EU it's quite a bit more automatic, since they have treaties on the subject. So a judgment in Spain would be much more easily enforceable in the UK than a judgment in US.)

    The leading case on the foreign law enforcement judgment is Jimmy Wayne Adams and others v. Cape Industries plc and Capasco Limited [1990] 2 WLR 657. Steven Loble acted for the plaintiffs in that case which involved the common law enforcement of judgments obtained in Texas by 206 plaintiffs injured by asbestos. The judgments were obtained against the defendants in the United States District Court for the Eastern District of Texas Tyler Division and proceedings were brought in the High Court of Justice in London to enforce the judgments.

    (2) It would be contrary to natural justice/public policy to enforce the judgment on the grounds that there had been no proper judicial assessment of the damages.
