  1. BMI aside, it's a slippery slope on Charging the Unhealthy More For Insurance · · Score: 1
    Disregarding the issue of using BMI to indicate a person's relative health, this begins the process of health insurance companies using more and more factors to decide how much you pay or whether you're covered at all. For now, it's BMI. Tomorrow it may be a full genome scan for latent genetic disorders or your susceptibility to other illnesses - obesity, alcoholism, sickle cell anemia, cancer, etc. Can you think of a better definition of a pre-existing condition?


    Next they'll consider the likelihood of your offspring being healthy - do the parents carry genes for inherited diseases? What are the odds that a child will have a genetic disease? They can refuse to allow to cover your offspring if you and your spouse aren't genetically 'fit'.

    A scary world, indeed.

  2. Medeco deadbolt locks - that's easy! on The Study of Physical Hacks at DefCon · · Score: 2, Funny
    "Medeco deadbolt locks ... can be opened in seconds with a strip of metal and a thin screw driver..."

    The thin strip of metal is called a "key" - you insert it into the "lock", and turn it. I'm not sure of the screwdriver's purpose. Perhaps you use it to scratch your head, wondering why you brought it along.

    So you're a boat that is typically used for transporting goods, vehicles, and passengers across relatively short distances that has been pressed into service carrying magical paraphernalia for Hogwarts, I presume?

    Perhaps you meant "The Spelling Faerie" or "The Spelling Fairy"?

  4. I know of one DRM technique that hasn't ... on The DRM Scorecard · · Score: 1

    ... been cracked, and no, it wasn't for lack of popularity. The original Divx security was never broken. It was as close to a perfect system as has been deployed in that it did not rely on information burned into the player and information burned on the disk. It actually updated its crypto keys every time it phoned home. The security processor was not part of the parent player - it was a separate, tamper-resistant gizmo with self-destruct tendencies. If you didn't pay your bill or the box couldn't phone home, it wouldn't play any Divx disks.

  6. Re:Why this IS important on openMosix Is Shutting Down · · Score: 1

    No problem. To your point, though, there's a little-used half-duplex standard called 100base-T4 that uses all 4 pairs. Current 10base-T and 100base-TX only use two pair, one in each direction.

  7. Re:Why this IS important on openMosix Is Shutting Down · · Score: 1
    The other side of the interconnect problem is latency. You have a delay of 3.33 nS per meter of cabling at the speed of light. At 96 Gbps (I'm assuming 96 Gibps, i.e. 96 * 2^30), that's 344 bits per meter 'in the pipe'. Most forms of cabling transmit pulses at anywhere from .66c to .9c, so it's actually worse in real life.

    If I want to interconnect two machines across the street from each other (say 50m of fiber down to the street, another 50m across the street, and another 50m to the other machine), that's a microsecond round trip, ignoring processing time on the other side. In other words, you could send 103kb+ one way in the same time it takes to send a single bit and receive (instantaneous) acknowledgment.

    Raw network speed isn't the only variable in the CPU-CPU interconnect equation. We can raise bit rates, but we're going to have a hard time raising the speed of light!

  10. Crunching the numbers on Digitizing 100 Years of Astronomical Data · · Score: 1
    If we assume there are a half million plates as the article states (let's call it a 512K, i.e. 2^19), and there's a petabyte (2^50) worth of uncompressed data on them, that's 2^31 bytes (2GB) per plate. Assuming 3 bytes/pixel and square plates, that's about 26750x26750 pixels. With a 12x12 inch plate, that'd be about 2230 pixels/inch. If the plates are smaller, say 4 inches, that goes up to a more respectable 6700 pixels/inch.



    Cost of storage? Free!!! They should get a few gmail accounts and store the scans there. Occasionally mail them between accounts for redundancy. 8-)

    I drive a 2k3 Cooper S like a demon possessed, and average 32 mpg between fill-ups. I'm sure if it weren't so fun to drive I could bump that figure to over 40. The Cooper S is quite a bit larger and more comfortable than the Smart car, I feel certain.

  16. Re:Too complicated! on Perfect Silicon Sphere to Redefine the Kilogram · · Score: 1
    The attraction of using centripetal force is that over a small area, you can design a (very nearly) perfectly uniform gravitational field. Note that the strength of the field need not be any exact value, just uniform.


    My original thought was that by setting the velocity of the mass to exactly 1 m/s and and the length of the string to exactly 1 m you'd be left with the definition of a kg. It seems that what you're left with is 1 N.

    We've got a precise definition of the second:

    the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom.
    and the meter:

    the distance traveled by light in absolute vacuum in 1/299,792,458 of a second
    Why not tie the kg to the second and meter via the Newton? 1 Newton is defined as 1 kg * m * s^-2. Using centripetal force in a plane normal to the earth's gravitational field eliminates gravity from the equation.
