    Not in all cases. Exemplary point: Antibiotics. They're already over-prescribed and as a result, we have massive problems with stuff like MRSA.

    Yes, in an ideal world we'd all have perfect information and be perfectly rational. However, we don't live in such a world and I've had a cashier tell me that he's taking antibiotics to prevent flu (I don't even know which idiot prescribed the stuff).

    As a result, the access to some drugs has to be limited in order to prevent secondary effects from happening. I couldn't care less about idiots who shot their immune system to hell with antibiotics - I do care about the multi-resistant bugs those people are training.

    Maybe you should whip out a calculator for once and calculate g-forces. A mere centimeter more means a lot less braking force to your head.
    In physics we call what happens there a "plastic deformation". If you don't wear a helmet that energy, instead of cracking the helmet, will crack open your skull.

    Again, it's not the homeopathy which works, it's the placebo effect which works. That is why there are no side-effects - because you believe it to have only positive effects because you're told there aren't any.

    However, if you were to do a trial drug test where you handed out homeopathic "drugs" and told one sample group that this particular "drug" would cure them but also possessed some side-effects... then you would actually get side-effects!

    Because of placebo's evil twin, the nocebo.

    Shadow of the Colossus won't work, though. I've got an i5@3.5GHz and a Geforce560Ti - and it won't run at more than 20 FPS. The developers of the emulator themselves stated that SotC is very demanding. Stuff like FinalFantasy works, however - though even that one slows down during the odd scenes.

  7. Re:Recommended Reading on FBI To Review Use of Forensic Evidence In Thousands of Cases · · Score: 1

    You're committing the same fallacy hardliners usually do when it comes to crime. Their usual one-stop answer:

    Harsher punishments.

    However, for deterrence (and that's what we're talking about here) to work, you need to factor in three things:
    - Adequacy of punishment (yes, adequacy. Punishment should be neither too harsh nor too soft.)
    - Reliability of punishment
    - Temporal adjacency of crime (meaning, that catching the perpetrator after several months has zero effect on deterrence)

    All those three have to work in conjunction, simply raising one will not have much of an effect.

    Though that's all beside the real problem: Punishment is not effective. The deed is already done.
    Which means that we should rather work on crime prevention measures. It's actually the same as with raising children: Punishing a child for doing something wrong is not really effective - because thus it's only taught what it should not do (maybe. See above). Rewarding the child for doing the right thing is the better way.

    Which means, when it comes to adults, find them some work.

    Ah, but that's the beauty of it: You don't need to know the number of duty cycles.
    You exchange your empty battery for a charged battery with the assurance of the fuel station that this battery carries the charge you just paid for.
    And if that one's empty, you'll replace it again.
    Furthermore, you can insert some electronics to store and display statistics - no need to sell a dumb battery.

    Again, a solvable problem.

  11. Re:Gasoline-like energy density on IBM Creates 'Breathing' High-Density Lithium-Air Battery · · Score: 1

    Why? The charge level for a battery can be determined and is an easily solvable problem.
    Also, we already have rechargable batteries with the AA form factor which have capacities from 1600 mAh to 2200 mAh (last time I looked).
    Just add some kind of conversion factor at the station, something akin to "equivalent to 60 liters of gas" and you're done.

  12. Re:Gasoline-like energy density on IBM Creates 'Breathing' High-Density Lithium-Air Battery · · Score: 3, Insightful

    You'll most likely still need to drive to a "fuel station", regardless. Filling such a high capacity battery inside of five minutes requires an incredibly high current.
    While certainly not impossible, the strain on energy distribution and the amount of wiring (the wire has to be thick to withstand the current!) will make it cheaper to have a few dedicated charging station rather than every house on its own.

  13. Re:Gasoline-like energy density on IBM Creates 'Breathing' High-Density Lithium-Air Battery · · Score: 4, Insightful

    Solved by standardized connectors and form factors.
    Instead of charging the battery in the car, exchange the empty battery for a loaded one.

  16. Re:Livescribe on Ask Slashdot: What Is the Best Note-Taking Device For Conferences? · · Score: 0

    Actually, the best way to take notes is after the lecture. That way you
    a) have to pay attention during the lecture and
    b) have to engage your brain again after the lecture to take notes of what you found noteworthy.

    Taking notes during lecture does not make you more attentive, it's actually the opposite. Because your brain effectively cannot do more than one thing at a time.

    I see this effect every day in school - I'm a teacher. As soon as I tell my pupils to take notes, it becomes very difficult to get their attention again. That's why I'm planning every lesson in such a way that there are dedicated note-taking periods, but also periods during which I say: "Pencils away!"

    When I'm letting them do experiments, one pupil of the group is the dedicated note-taker - it's his sole job to take notes and nothing else (just like the other pupils have other jobs than taking notes!). The roles are rotating - but this is more effective than having every pupil of the group do his own not-taking.

    You're trying to convince us here that two different states of coma are comparable to braindeath. This is not so. Not to mention, by the way, that you have better odds of winning the lottery than waking up from a coma after you've been in said coma for more than a year.

    I'm highly doubtful of stuff like "synthetic experience", "I feel something is wrong" and so on and so forth. It's the exact same language audiophiles use.

    Not to mention that stuff like that is a self-fulfilling prophecy - you're sensitive to the kind of lamp and you're thinking that something must be different, so obviously there is something different.
    Particularly in light of the fact that our perception of the world is highly subjective - our preconceptions colour our perception (pardon the pun), just as it obviously is in this case.
