  2. Re:Eye problems on User-Adjustable Glasses · · Score: 2
    When an out of focus image is presented to the retina it stimulates growth of that part of the eye resulting in a change in eyeball shape. This is the normal mechanism by which the lens-retina system forms and maintains a system that can focus in an organism over its lifetime[...]

    This, incidentally, is one of the reasons for myopia in our modern society. The eye is adjusting to long periods of close up work to which it is not well adapted. This causes the eye to grow into a maladapted shape.

    That's interesting, intriguing, and could quite possibly even be correct. Do you have any links to further evidence?

    And does this theory have anything to say about the causes of astigmatism?

  3. Re:The morning on November 19th on Leonid Meteor Shower 2002 · · Score: 5, Informative
    Morning for which time zone?

    Basically for every time zone. You see, as the Earth rotates on its axis, it is also orbiting the sun. Some part of the Earth has to be plowing headlong into the trail of dust. And that has to happen at either the "dawn" line or the "sunset" line (think about it.)

    If the Earth spun the other way 'round, meteor showers would always be best just after sunset. But, sadly, I was not consulted during the design phase...

    Now that's the general principle. In this case, astronomers are predicting two particularly dense sections of the dust trail, one intersecting Earth's orbit at dawn Europe, and another around dawn East Coast Americas. But even people not in these locations should see the best local view at about an hour before sunrise.

  4. Re:Reliability of the disk on Sharing a SCSI Drive Between Two Boxes Using Linux? · · Score: 2
    The way I see it, the only thing this avoids is kernel failure.

    I don't think this proposal avoids even that. If Server 1 and Server 2 are connected to Disk 1, and Server 1 goes belly-up, there is bound to be information in RAM cache that Server 1 didn't get to write back to Disk 1 before it went down, even it it syncs every millisecond, which would be horrible performance-wise.

    So when S2 detects the crash of S1, D1 is unclean and an FSCK is required before D1 can be cleanly remounted. That's going to take a while.

    So, the common case is software crashes, and the uncommon case is disk failure. This solution doesn't seem to save you much, if anything, in the common case, and saves you nothing at all in the catastrophic case. I think you'd be better off with one server which can be quickly rebooted, easily debugged.

    But the extra cycles there are for SETI@NotHome.

    Seriously, I agree with your main point. When I'm asked how many computers I own, I have no clue what to answer. Each of my microwave ovens probably has one, my toaster has one, all of my desktops and servers have one, but more likely several, and who can guess how many processors General Motors might have put into my car? Not to forget the ones in my VCRs, pocket, watches, modems, calculators, thermostats...

    And should two broken computers, out of which one working computer might be constructed, count as zero, one, or two?

  6. unionfs 2-fs limitation shouldn't be a big deal on Unionfs for Linux? · · Score: 2
    if they can be chained...

    For example, maybe you have

    /dev/hda1:/media/mp3 as /tmp/a/mp3

    /dev/hdc1:/media/mp3 as /tmp/c/mp3

    /tmp/join/a unions /tmp/a/mp3 and /tmp/b/mp3
    /tmp/join/b unions /tmp/c/mp3 and /tmp/d/mp3
    /all/mp3 unions /tmp/join/a and /tmp/join/b

    Mind you, I haven't looked at whether any given unionfs implementation would support this configuration, but loopback-type support typically isn't hard.

    As as aside... wherever I type "space slash", slashdot eats the space, making the above a little harder to read than it should be. Anyone know why that is, and/or a workaround?

    I wasn't disagreeing with you, but trying to correct and elaborate. Yes, saving spam won't help, and ex post facto is why, because it's not currently illegal in most places.

    Where I wrote "prohibition," read "prohibition against ex post facto laws," and maybe you'll see what I was trying to say.

    It's ex post facto, and it applies to both the Congress and to the States. See here.

    The prohibition doesn't apply in this case because this anti-fax-spam law has been on the books since 1991, so all of fax.com's supposed violations clearly would have taken place while the law was already in force.

    Here's the decision.

    I'm not sure how much this applies; prohibiting police from doing random ID checks is not the same as requiring ID at established security checkpoints. Who wants their every move to be in a database? Thank goodness there are not yet checkpoints at every state border crossing.

  11. Re:Try Emeralds on Diamonds - Are They Really Worth the Cost? · · Score: 2
    Funny the way this thread has unfolded. I designed my wife's ring to have a black opal, a ruby, and an emerald, with the black opal in the center to sort of 'connect' the colors. Symbolism all over the place. Her birthstone and mine, and the emerald 'cause it's always been my favorite, so it can represent her being "my favorite."

    She dug it plenty, and still digs it plenty. (How can one consult with one's intended on the ring design if the proposal is supposed to be a surprise?)

    But that black opal was by far the largest part of the ring's cost.

  12. Re:There is an workaround on Finding BIOS Upgrades? · · Score: 2
    Your problem is that you can't _boot_ from a HD larger than 500MB -- because as soon as Linux kernel is loaded, BIOS isn't needed any more anyways.

    Wouldn't it also work to simply put a /boot partition in the first several cylinders of the disk? I think, then, that no floppies would be needed.

    Don't count on a check. The article says "refunds or credits". What company ever writes a check when it can simply print the money in the form of a coupon?

    That way, they get you coming and going. You paid for the OS you didn't want or need, and you don't intend to buy anything from them in the future anyway, so the coupon will remain unused... Microsoft smiles. The lawyers smile, too, since they got paid. Consumers? Hey, you won, right? Be happy about it.

    Small? Compared to the size of a planet, maybe. These are stabilizing gyros, not navigational. Didn't read the article?

    The loss of function of the desk-sized 363 kilogramme (800 pound) gyro emerged after astronauts reported a loud, growling noise inside the International Space Station.

    On the other hand, that loud growling was probably the astronaut's libidos at the prospect of escorting supermodels.

    And the -r seems out of place, too, since you've already selected objects of type file with your -type f directive. How are you going to recurse a file?

  23. Re:Tsunami? on Your Own Luxury Submarine! · · Score: 1
    Extrapolating here... I believe that in the middle of the ocean, a tsunami would look like a noticable wave (say one foot high). So, that is, noticable only in an otherwise calm sea, and appearing to come out of nowhere.

    Submerged, I doubt it would even be noticable.

    Tsunamis don't take on their great height until they "climb" onto the continental shelf. So disregard what I just said, if you're not far enough out to sea when one runs across you. What would happen then?

    Let's see. If you're submerged, you'd probably feel a noticable current. If surfaced, you'd be bounced around quite a lot. But so long as you have your doors closed, this being a submarine, you're probably as easy to sink as a cork.

    it's perfect for this sort of use.

    You don't have to use ASCII, just start with a number mapping that conveys the information you need. Maybe 1-26 for letters and a few more for space, punctuation, etc.

    Then pull the top number off your pad, add your code number, write that down. Tedious but not difficult, and your friend just does the same thing in reverse to decode.

    Plus it's unbreakable, so long as no one gets a hold of your pad and you never reuse it.
