    Well, the original poster did say "how about a building code" that makes plugging in your cat5/fiber pipe as easy as plugging in the proverbial toaster. The beauty of the system is that you get to sell the same old devices that network using proven technology with huge MTBFs and all the attic crawling is done by professionals before they put the walls on. No house mods necessary (of course if you WANT neon lights and an extreme freon powered person cooler you can have those installed).

    So the building code to install cat5 cable as standard is easy to draft, and is already in the planning stage for countries like singapore

    As for your observation on security - yes, mm wave and microwave surveilance and snooping is common knowledge now, even to the point of being portrayed in movies like bruce willis and denziel washington's _the siege_.

    It would be a lot more expensive though to build one of those jar type things that gene hackman lived in in _enemy of the state_ using common materials and still have the place looking like a home. I would say that that anti-tempest security building standard would be quite hard to do.

    1 it would be impossible to get those kinds of intense magnetic fields without using superconductors. Conventional conductors would melt with the kind of electrical current you would need.

    2 unfortunately buckyballs don't seem to lubricate. but see that post on FLIR made with nanotechnology for more commercial nanotech products.

    3 You want great 3d uses of holograms? Try imaging This technique could generalise for anything else you want to look at under a microscope in 3D. Cells. Fuel rods in a nuke reactor. the hologram captures all that data at the quantum level.

    the application is commercial because there are hologram companies that sell equipment to other companies. If you want to get into it yourself for next to nothing look at this link and search for hologram

  8. public != insecure. on Because Only Terrorists Use 802.11 · · Score: 2

    Public libraries - usually requires library card with name and address on record. otherwise the person at the loans desk will have seen you. That's part of how they caught that big identity theft guy.

    kinkos - never used it myself. Is there a security camera behind the desk?

    hotel room - the clerk saw you, and would probably identify you in a line up. Happens to people all the time.

    Tourist information center - clerk and camera.

    Airport lounge - you probably have an air plane ticket. Interpol is great at tracking those. using a fake name/passport just makes them feel like it's going to be a good day.

    Highway rest stop - actually this might be a pretty good one. The only thing I can think of is taking biometric evidence like a fingerprint off the coin you fed it. unless there's a clerk and camera.

    internet cafe - clerk and camera.

    cable company kiosks - Do you mean those kiosks which stand in the middle of the street? They usually are very crippled in their interface. you can't even run ping. I dunno. Maybe you might be able to exploit them.

  9. building security != network security on Because Only Terrorists Use 802.11 · · Score: 2

    Read the international building code. and the international residential code.

    the interesting thing is that there's even regulations about what kind of security you are prohibited from putting on your building.

    The thing is though building security != network security. while door locks and building alarm systems and indeed buildings themselves are well understood, the wireless network and the way we want to use it is new and evolving.

    Imagine if you were trapped by an earthquake under tonnes of microwave transparent material, and the only thing in your little coffin shaped cavity was your fully charged and still operational laptop. You fire up snort and find a wireless lan and then attempt to contact the admin...

    Network security could be a matter of life and death.

  10. Re:airships on Fuel Cell Powered Backup System · · Score: 2

    good point. of course, it would take quite a big reactor pile to loft an aircraft carrier, and you'd have to insulate it somehow to prevent huge convection currents within and the baloon volume becoming an enormous IR visible target.

    but I take your point: airships can be filled with more things than a lighter than air gas, including heated air.

    I just chose hydrogen because it is very abundant, and works at ambient temperature.

  11. hydrogen compressor on Fuel Cell Powered Backup System · · Score: 2

    they should bundle it with a mains powered hydrogen compressor, so you can store hydrogen safely in your own canisters when times are good.

    I'm betting that running hydrogen through a normal air compressor would be asking for trouble.

    By gently heating a hydrocarbon fuel with a catylist, you can get nydrogen gas out of it. If this technology matures you could end up with a portable powerplant that runs on pure H2 gas and a wide variety of other fuels.

  13. airships on Fuel Cell Powered Backup System · · Score: 5, Interesting

    The goodyear blimp is only a flying billboard, whereas the hindenberg was more like an ocean liner.

    They were called airships because they were originally intended to do everything a ship could do, only from the air. The germans used airships to attack britain in the first world war and there were plans for airborne freight for go-anywhere delivery of parcels at a fraction of the cost of other courier systems.

    I suppose that if engineers really wanted to work at it and spend a lot of money, we might have nuclear powered, hydrogen lofted aircraft carrier blimps defending america today - stealth airbases that could suddenly appear deep behind enemy lines and move around at will.

    alternatively you could have a solar powered blimp-yacht for recreation: solar cells on the top of the air bag generate electricty, a scoop on the front collects h2o. electricity splits the h2o into hydrogen for loft and propulsion and oxygen. Fuel cells turn the hydrogen back into electricity on demand and drive the electric motors connected to the propellers.

  14. Re:Molecular computers may benefit from this... on Molecular Photography · · Score: 5, Informative

    Synchrotrons are used for x ray crystalography. they can produce X-ray photons at a wide range of frequencies and you can carefully select the photons you want using an x-ray monochromator.

    The X-rays will not tell you anything about the nuclei of the molecules you are looking at, as the photons go through the electrons in the crystalised protein they will make an interference pattern, and from that you can calculate the shape of the electron cloud around the molecule.

    Note that this gives you no infomation on the quantum state of the nuclei, which is what this quantum computer needs to know.

    Nuclear Magnetic Resonance molecular analyisis works in a similar way to Magnetic Resonance Imaging, just on a smaller scale.

    The moment a "clone" brand comes out which the user can actually get under the hood of and make insane mods to. Nobody ever races the same vehicle that just anybody can go to a shop and buy. It has to be all custom. Heck, even atheletes who race their bodies tune and shave and tweak every last muscle fiber before that starting gun goes off.

    I think that 90% of the race happens before the racers are at the start line.
