  1. Further, cancer risk may be a power law on Pittsburgh Cancer Center Warns of Cell Phone Risks · · Score: 1

    The fact is, most Bluetooth headsets are Class 2 devices, which have a maximum power of 2.5 mW. This is orders of magnitude less than the emissions from a cell phone, which can peak at 500 mW.

    Not only that, cancer risk may increase as a power law of exposure, rather than linearly. (Depending on the mechanism of damage, of course.)

  2. Re:Good on The Death of Nearly All Software Patents? · · Score: 1

    From my experience with watching how the companies I work for treat patents, they aren't used offensively. They are used to:

    A) Show proof of innovation to venture capitalists, stock holders and management
    B) Ensure they will have the right to use that process, so some other guy won't use a patent offensively against them.

    And this, plus:

    C) Give them something to trade when somebody with a patent on something they're doing goes after them

    are how they're usually used, at first.

    But when a company gets seriously behind the pack in competition and is looking at bankruptcy, its executives normally refuse to abandon the stockholders, employees, and their own paychecks and let it go quietly into that dark night. At that point they will often dig out the patent portfolio and start a bunch of actions against competitors who are beating them at their own game, on the chance that some of them are doing so using their own patented technology.

    If the competitors ARE using their certified inventions, and if they can prove it (or are close enough that the competitors decide to concede the battle), they can obtain a revenue stream, a lump of cash for themselves, and/or access to some of the comptitors' own "secret sauce recipies", while penalizing the competitor and leveling the playing field. This might bring them back into the game - or at least mitigate the damage and extend their company's life.

  3. Can't prove CORRECTNESS, can prove other stuff. on The Death of Nearly All Software Patents? · · Score: 1

    Fact is, it is possible to prove the correctness or otherwise of a computer program, so it's mathematics.

    Actually it's not possible to prove correctness - though there's other stuff you can prove.

    Consider:

    What constitutes "correctness" depends on the intent of the program. A perfect "cat", for example, is broken if what you wanted was "sum".

    So if you have a method to formally prove correctness of a program, you have to specify to it what the intent of the program is. And you have to do that in a formal way. This, itself is a programming problem. So you have ANOTHER program which may or may not be correct, as a necessary step for proving the correctness of the first program, and this new "program" is itself not proven correct. Infinite regress.

    The "correctness" proof, meanwhile, is demoted to a proof of equivalence between the two "programs", which are merely different ways to express the same intent.

    Of course this can be very useful: The two (or more) forms of expression of the intent can be wildly divergent. Expressing the same intent in two or more divergent forms drastically reduces the chance that the same error is made in all of the expressions. Combined with an automatic way to prove equivalence between them (and thus root out the errors that don't occur in all of the expressions) and you end up with a drastic reduction in the number of errors in the final product and a drastic increase in the chance that there are no undiscovered errors.

    Other things that can sometimes be proved about programs include impossibility and membership in a class of programs with equivalent degrees of computational difficulty.

    No.

    For starters, time is usually very precious when such a car is needed. (You lose much of a day off both ends of a vacation, for example.) Such proposals have the consistent flaw of valuing the driver's time at zero.

    Then there's the extra driving and related fuel costs to pick up and drop off the specialty vehicle. (If you're 50 miles from the rental company - and in areas where you actually need, say, off-road capability that's a SHORT distance, you're talking an extra 200 miles of driving.)

    Then there's the enormously higher cost per passenger mile of a rental vehicle - which has to make up the company's costs for operation, losses, damage, sitting idle waiting for a customer, etc.

    Then there's the risk of the vendor not having a suitable car when you need it. (He has to have a lot of cars sitting idle a lot of the time to keep that risk low, amortizing that cost over the time it is rented - see above about costs of idle time.)

As such it's accessible to psychopaths.

    If you want broadcast, broadcast.

    When the ISPs all support multicast in a compatible way (or even support it at all) we can switch over to that. Unfortunately many have not chosen to do that - at least so far. (Not surprising, since many of them are broadcast media conglomerates. Multicast-for-the-masses would enable their competition on a shoestring-budget level.) Meanwhile, live torrents do the same job for the users without additional support from the ISPs.

    Yes it's not "efficient". But the main cost of the inefficiency falls squarely on the pocketbooks and infrastructure of the ISPs - the very people who have chosen not to provide the more efficient form of transport. How poetic.

    Perhaps, as this begins to deploy and places an additional load on the ISPs' infrastructures, they will change their minds about promoting multicast and rush to deploy/enable it.

    If they hurry they might head this off. If they wait until it's widely adopted they'll probably be stuck with it. Why should the users switch to something that's more efficient for the ISPs - but incompatible with what they're using now - when what they're using now does the job for themselves just fine?

    So if the reduction in latency and upstream traffic from going with multicsast isn't enough to convince the users to switch, the ISPs will be stuck begging the authors to upgrade the code to use multicast distribution where available as a friendly gesture. B-)

    There's a proverb related to that: "Fast nickels are better than slow dimes."

    There's also a similar law in wind power: The Betz Limit. A mill gets power by slowing the wind. But slowing the wind also reduces the amount of air going through the mill, from which you can extract power. Take ALL the power from the column of air that passes through your mill and you get no air and no power. Between not slowing the air at all and stopping it completely there is some amount of power collection where you get the most power from it. Betz computed that.

    Similarly, if you want to bleed an animal and collect the blood there is some maximum amount you can take (whether expressed as a rate per month or a percentage of the blood on each pass through the heart). Take more and the animal is weakened enough that its blood production slows and can't keep up. Continuing to collect at that rate will kill it.
