  1. Re:Yet Another Overblown Crypto Hack on More on Newly Broken SHA-1 · · Score: 1

    CSS wasn't secure when it was introduced, it's only there so that anyone cracking it is violating the DMCA. Although you can't make something which in a single form will always be secure, it should be possible to make a hash/crypto scheme which is secure as long as you keep extending the key - 128 bit hash/crypto key for now, make it 256 when computers get a bit faster, then 512 and so on. A good enough algorithm should stay secure when doing this.

  2. Re:Collision free hash? on More on Newly Broken SHA-1 · · Score: 1

    The main reason they are fixed-length for signing is that the actual encrypting-with-private-key bit is computationally very expensive, and worse, it's fully exponential with the length of the message. When pgp was first written, signing an actual email would have taken days for the average desktop PC. Nowadays you could probably manage a short email, but your desktop PC couldn't sign a 700mb iso in several times the age of the universe. The hash is meant to maintain the security (because you can't change the message without changing the hash) whilst meaning you only have to do the actual calculation on 128 or 256 bits.

    Yeah, definitely 2.0, possibly even 1.x. If you want real security and stability, that's what you should go for. 2.0 is still maintained, isn't it?

    Hmm, you're right. Guess I'd better switch to tiger or whirlpool, at least once gpg has support for them.

  5. Re:Uses? on 42nd Mersenne Prime Probably Discovered · · Score: 1

    But there are no primes not in the list, because the list is a list of *all* the primes. So you don't need to worry about it being divisible by two or more primes from the set of numbers greater than your biggest old prime, because there are no primes in that set, because the original list is the list of all primes.

  6. Re:Uses? on 42nd Mersenne Prime Probably Discovered · · Score: 1

    Why not just say it can't be divisible by any of the primes in the list, thus it's a new prime?

    They already exist. RIPEMD-160 is tried and tested and seems secure, or at the more experimental stage there's Whirlpool.

  8. Re:Municipal WiFi is not free. on Municipal Wi-Fi Battle Moves to Texas · · Score: 1

    It's far more cost-effective than everyone having their own separate connection though. So it's something that makes sense for the city to run. Like municipal garbage collection, or anything else the city does. It will benefit everyone, some more than others but that's true of everything, and the benefits will be more than the costs, so the city should do it.

    Giles, is that you? It does have to be a new prime, because he has stated at the start that he is assuming his list contains all the primes.

    No, but the guy who hired him (or the guy who hired that guy, or so on up the chain), and didn't do something about it when he failed the first time, is the same guy who hired the guy who runs your telephone network, and is responsible for ensuring he does a good job. Still feel happy using them?

    You're probably right, although I wonder about putting it on a large lorry. But that's not enough to stop it happening. Get ship, put bomb on dead man's switch in case you get boarded, then head for the middle of New York. Run ship aground on manhattan island if possible. Detonate bomb.

    You don't need to enrich it if you can get enough raw Uranium. Just put it in a centrifuge and get the fissible stuff out. It's pretty inefficient, but doable.

    How preventable though? AIUI you can just go and dig up uranium yellowcake to centrifuge into weapons stuff, as long as you're not worried about irradiating yourself

  14. Re:dirty bombs on Can Terrorists Build a Nuclear Bomb? · · Score: 1

    Yes, the effects of the radiation are purely psychological. But they will be big. Americans refuse to live within 30 miles of a nuclear power plant, and that's when we know there is no output above background. Can you imagine anyone being willing to live somewhere they know has been irradiated? You can tell them it's safe all you want, but for practical purposes the area will be uninhabitable.

  15. Re:Its Microsofts Right on Microsoft Blocking Wine Users From Downloads Site · · Score: 1

    OK, not everything. But I can use the program in the fashion it is sold as being for (an OS and an office suite in this case) and make any copies necessary for said use without needing a license.

    Averages over a long period are far easier to predict. You can probably predict where a baseball team will finish the season a lot more accurately than you can predict how they'll do in their next game.

  19. Re:BSD license is't dying on OSI Hopes To Decrease Number of Licenses · · Score: 1

    Polite people will do that anyway though. If you think getting more code makes the difference, why not go GPL? I just feel it's not worth going through the fuss of having a license just to make sure my name remains on the code. If someone's nasty enough to remove my name and claim it as their own work, I'm not going to worry about stopping them, just feel a bit sorry for them.

    The fact that I own them, and the laws of my country. A copy which is necessary for the intended functioning of a computer program is not an infringing copy under UK copyright law, so there is no law preventing me from making said copy.

    DRI lets you bypass the X server, pretty much. Same with accessing OpenGL directly, that's the mesa layer there. Basically you can skip any of the layers you want to, every API is exposed to you.

    That's an interesting piece of history. However, having tried both and being able to switch at will, I feel the icons on the right make more sense. Why? Because there is a connotation, at least in my culture, of things beginning on the left and ending on the right. So it makes sense for the close button to be the rightmost thing on the titlebar. Minimise also belongs over there, because that's a sign I won't be using the program for a while. Maximise could be said to belong on the left, but when two out of the three should be on the right, that's the sensible place to put them
