    I don't think so. If this never gets to court or if he's acquitted, the constitution is fine.

    The constitution that allows such an arrest is not by any definition "fine".

    You can walk into any house in America and find what they allegedly found. Gasoline, cleaning fluids, flour (yes flour), steel wool scouring pads, and matches, wires for the lamps, cell phones, the list of things that police can designate as bomb making materials is endless.

    The only probable solution would be to dedicate specific channels for their use and have rigidly enforced laws in place which forbid usage by consumer devices.

    I'm not sure how you rigidly enforce laws in battle field situations. If you could, why not just make a law against the enemy carrying weapons?

    There are two key requirements in the Darpa Challenge:

    1) High priority radios in the military and civilian sectors must be able to operate regardless of the ambient electromagnetic environment, to avoid disruption of communications and potential loss of life.
    2) Response operations, such as disaster relief, further motivate the desire for multiple radio networks to effectively and efficiently share the spectrum without requiring direct coordination or spectrum preplanning.

    In the end I suspect that the winning entry will pay little heed to the regulatory frequency allocations, and fall back on the FCC standard of non-interference by instantaneously finding unused frequencies over a wide spectrum and pushing messages through those spaces in small encrypted bursts so short that licensed users of that bandwidth would not even notice it. Alternatively you might be able to embed your transmission within already widely used frequencies for digital television, AM /FM radio, by using the gaps between allocated frequencies.

    Why should they read Claude, when what they are asking for is not anything to do with bandwidth or power, but simply competing transmissions, some perhaps hostile? The DARPA Spectrum Challenge places no explicit restrictions on bandwidth, and perhaps only portability restrictions on power. I rather suspect DARPA has already developed radio technologies that would make Mr Shannon's jaw drop.

    Someone watches all of those gamed. Every uninteresting baseball inning, every boring back and forth soccer kick, even days long cricket matches.

    There is no shortcut magic that ESPN has. They just have lots of eyes.

    If you don't have that many eyes, Artificial Intelligence has a much better chance of picking up a remote encampment or a caravan of cars, or even pack mules and foot soldiers in hours of desert streaming by. At least it eliminates the 90% of the video stream that holds nothing of interest.

    Seriously, real world code is by definition 'real world' and doesn't live by the theoretical pillars of design. It has to deal with actual deadlines, finite resources and of course office politics.

    Exactly.
    Where the professor can take 6 months to prepare a small simplistic demo application custom tailored to demonstrate his (pet) coding methods and design standards, in the real world you have to get things done, not in 6 months, not in 6 weeks, and seldom in 6 days. You might have 6 hours on a good day.

    But corporate world code runs every single day, not twice a semester. Its "good enough".

    systems are long lived, and few if any are fully understood by the current staff, because the guy who wrote it moved on 8 years ago.
    And Yet, it gets the job done day after day, year in and year out, because people watch it and know what to expect.

    Do houses fall down because of bad 2x4s? Virtually never. Maybe after years of
    remodeling, rewiring, re-plumbing, the place will burn down, but there is usually
    a recent idiot involved, rather than the original builder.

    We build things "good enough" in this world. Not Perfect.

    That does not address the fact that the summary states that conductivity does not change as the wire is stretched.

    The summary states no such thing.
    It states that conductivity reduction changes are offset by other changes that reduce resistance.
    However that offset is limited to a very small range of current and voltage. Mostly it works for voltage and amperage that would be
    found in signaling, not power transmission.

    One can not negate the basic laws of electrical transmission that huge amperage can not be carried on tiny wires.

    So, there is no difference between "off" and "hibernating."

    The difference is the lack of a resume file. The computer is not hibernating if this file is missing or was never written because the power was switched off without taking the time to hibernate the computer.

    I believe the intent is to prevent pedophile pedators from clandestinely communicating with potential underage prey. However, since sex-offender status is applied to more than just pedophiles, I would think that this is overly broad.

    Exactly. In many jurisdictions, you become a sex offender simply by peeing in a back alley in the dark after the bars close.

    There really needs to be a legal redefinition of the terminology to weed out the pedophiles from the person on the losing side of a he-said/she-said.

    Exactly: They aren't breaking encryption, they are simply surfing for keys.

    Quote TFA:

    So, how does it work? Elcomsoft Forensic Disk Decryptor acquires the necessary decryption keys by analyzing memory dumps and/or hibernation files obtained from the target PC. You’ll thus need to get a memory dump from a running PC (locked or unlocked) with encrypted volumes mounted, via a standard forensic product or via a FireWire attack. Alternatively, decryption keys can also be derived from hibernation files if a target PC is turned off.

    Note the basic misunderstanding embedded in that last sentence: Turned off != Hibernated.

    While this tool might help you break into a computer you found hibernated, or running while locked, it won't do any good if the power cord is yanked, or the encryption software was intelligently written to only store its key an some volatile memory.

    so shouldn't this alter the conductivity of the 'wire'? http://en.wikipedia.org/wiki/Electrical_resistance_and_conductance#Relation_to_resistivity_and_conductivity

    One would think so.

    But you could design for that, simply by using the smallest diameter as your critical dimension when selecting wire size.

    Of course it also allows for some new circuit elements, those that can measure stretch via voltage drop, which might be very useful in robotics or prosthetics.
    In short it might not be as much of a detriment as it is an advantage.

    6+ years puts you into the long suffering crowd, (with me) to whom almost anything approximating stable earns high praise.
    Somewhere around 4.6 it actually became fully functional again. I can't wait to try RC1. There were many releases where I
    wouldn't dream of trying an RC?, having been bitten too often.

    It has been a long and bumpy road. One more upgrade like 4.0 would probably kill this project completely. Its not totally the KDE Team's fault,
    there were far too many Distros that jumped on way too early, making 4.0 the default, then claiming they really didn't.
