    I always laboured under the impression that physics was a mere subset of mathematics.

    Mathematics is the servant of physics.

    Mathematicians are like tailors. They make a lot of clothes; various sizes, various shapes, various number of sleeves and legs. Physicists then come to the warehouse where these things are stored, and search for the proper clothes that will fit their experimental creatures.

  3. Re:No worrys. on Lost Nuclear Bomb Found Off Georgia Coast? · · Score: 1
    In the Mark 15 Mod 0, the third stage is the bomb's casing, which is made of highly-enriched uranium, almost pure U-235.

    If I remember correctly, the third phase is not enriched U235, but either natural or depleted uranium, the 238 isotope.

    U-238 *is* fissile. But the neutron has to have high energy. A slow neutron just gets absorbed and unstable U-239 nucleus is formed, the kinetic energy of the neutron not being enough to destabilize the nucleus. A fast neutron (with energy higher than if-I-remember-correctly 1.8 MeV) packs enough punch to kick the resulting nucleus over the potential barrier, so it splits and releases energy. So we need to have fast neutrons for U238 fission. These are produced by the fusion stage. So there is no need to use dangerous and expensive enriched uranium for the bomb casing.

    So maybe it won't be *that* bad...

    Publish anonymously or pseudonymously. There are ways to avoid being tracked down, some involving cybercafes, some (the more reliable) involving wardriving, some (the more expensive) using throwaway cellphones.

    As added advantage, if the thing is legal in the country where published, the probability the resources will be spent on tracking down the one who did it is quite low. Another possibility is to cooperate with somebody in Far East; China will do.

    A good hint for rapid dissemination is using mailinglists. While it's easy to take down a website, a mail sent to a list is usually on the way to all the listmembers in few minutes. Once a couple hundred tech-minded or freedom-minded people have their hands on the code (or specs), it's fairly impossible to restrict its proliferation; see DeCSS or the anonymous posting of RC4 specs.

    can't you just cover them over with something or disable them in the BIOS?

    When you disable things on hardware level, you can be reasonably sure they won't work anymore. When you just switch them off, there's still chance of getting them working again by banging the hardware directly via direct I/O and mapped memory access. Not too much of threat here, though. Modifying things on hardware level is fairly bulletproof from the software side, when well-done.

    When I see a guy with a soldering iron and a motherboard I become the personification of the "Are you sure?" dialogue box.

    Been there. There are fuses on the mobos, on the +5V lines to the ports; they often look like yellow or green resistors. (If they aren't there, then the traces on the boards play their role instead.) Messing with powered-on hardware (especially keyboards, PS/2 mice, and USB ports) often blows them. Replacement is simple; if it's a fuse, either change it or solder a Polyswitch fuse (better than a regular one, these ones will revert to conductive state few seconds after the circuit is interrupted) parallel to it, if it's a blown trace, repair it with a wire with an optional fuse (and if you omit the fuse, make sure the power supply stops working when shorted instead of going up in smoke). I also got a board with couple bad capacitors (from the batch of the Taiwanese ones that had bad electrolyte formula) that was unstable. Replacing them with elyts from other board that died for a different reason cured it. Addition of a TV card and a discarded 14" monitor turned it to a nice TV and a DivX player nearly for free.

    Otherwise, at least until the Palladium-grade chipsets start appearing, direct motherboard mods aren't too useful. It's usually better to design it as a PCI card (or USB device, if the operating speed isn't critical) instead.

    This presumes the passive wiretap scenario. MITM is different - Alice talks with Eve and thinks she's Bob. Bob talks with Eve and thinks she's Alice. Eve sits like a transparent proxy between them and has fun. It screws up the timing, but if Eve attacks the transaction on higher network layer, the timing of individual photons doesn't matter as both the Alice-Eve and Bob-Eve connections are standard-compliant. Which works not only for quantum crypto, but for more mundane things like SSH and SSL and anything that uses a key exchange protocol without authentication. (Moral: Beware of MITM.)

    You can spit into Eve's coffee if you're using authentication. If Eve doesn't have something that's Bob's when Alice asks for it (eg. a private half of a RSA key, or in symmetrical scenario some shared secret), Alice becomes suspicious. So either Eve does full-transparency without touching the data, and then MITM degrades to passive wiretap, or she reveals herself. (Moral: check the certificate fingerprints.)

    She can also modify the early phase of the protocol handshake, often unencrypted, and degrade security on purpose; eg. she can modify the server response that it allows only export-grade ciphers, or SSLv2 (which has a protocol-level bug), and then break the intercepted comm in her leisure. (Moral: disable support for easily breakable protocols, to prevent this style of attack.)

    Uh, why should I worry about whether or not one of the preferentially treated subjects" leaks the information? That is as likely to be helpful to me as not.

    That depends on what side you are. If you are the one who pays, or the one to whom the info leaked to, regardless of the color of your hat, you have an advantage against the ones who aren't.

    Which puts to disadvantage all the ones who aren't members of (or friendly with) big corporations or e-crime rings. For a small admin of a small network it means just that the adversaries have more time to write worms and that the time between a vulnerability getting known and a vulnerability getting exploited shrunk again, at least for the ones who didn't play the advance-info racket (who will pay for it once more, indirectly, in the form of bandwidth wasted by worms from even more machines patched too lately).

    ...you either get the lossy output that will produce artifacts when re-compressed,...

    What about applying some DSP technique on the decompressed signal in order to pre-compensate the recompression losses?

    The changes of characteristics imposed on the signal by the compression-decompression of XM broadcast/receive chain are known, or at least can be measured. The characteristics of MP3 compression are known as well. Some parts of the signal will get lost. There are three ways to cope:

    1) Suck it up and consider it good enough. Or use high-enough bitrate to make the losses not matter; the XM quality itself isn't exactly CD, so 256k MP3 or Ogg variable bitrate stream should be more than enough.

    2) Preprocess the analog signal from XM, adding/removing some input-dependent frequencies for the MP3 algorithm to throw away without showing recompression artefacts. Don't ask me how, this is a question for DSP people.

    3) Tweak the MP3 compression algorithm to use different model for throwing out information deemed unimportant, to compensate for the compression artefacts of the XM step. Again, question for DSP people.
