  1. What's in it for me? on PDF Tracking On the Way · · Score: 1

    This isn't a technology I am particularly fond of.
    It reminds me of how when I check-out at ToysRUs, they always ask for my telephone number. I know they are just collecting demographic data, but it is an invasion that really doesn't pay off for me directly.

    The reason I am OK with webpages knowing what IP address am coming from is ...
    1) apart from using an anonymous proxy - it is a necessary trade-off,
    2) it has always been this way, so I don't _feel_ like I am getting hosed
    3) it is something I know is happening and expect.

    The Remote Approach PDF...
    1) is not necessary (it just feeds the marketing drones)
    2) introduces new privacy compromises, so I _feel_ abused
    3) implements behavior a user does not expect from a document, without their knowledge.

    It also seems that my local path to the document is being sent in the clear. The only people who could use this information are people who are up to no good.

    I had the surgery done (and I would definitely do it again) - but the one down side for me was that I did give up superhuman vision. I used to be able to read the tiniest writing. Even the less-than-a-millimeter-tall letters on the new currency. Now I dont have that parlor-tick in my bag.

  4. Proves Desks are Clean! on Lifting The Lid On Computer Filth · · Score: 2, Interesting

    A desk is capable of supporting 10 million bacteria and the average office contains 20,961 germs per square inch, according to research.

    Do the math:
    10*10^6 / 20961 = 477 square inches

    So if the average desk has more surface area than 477 square inches, it is one of the cleaner places in your office! Can you put four sheets of paper on your desk?

  6. Re:Are there any good uses? on Gillette Pulls RFID Tags In UK Amid Protests · · Score: 1

    What I'd love is an RFID standard and a home re-programmer. Imagine, then if all your products came with RFIDs!
    When I get home from shopping, the re-programmer encodes the data in all the RFIDs of my purchases so that I am the only one with access to the data. Later, I can query my TV about
    -how many beers are in the fridge,
    -whether my favorite shirt is in the laundry pile or in my closet,
    - where I left my sunglasses
    - what was that book I was reading in the bathroom 3 months ago?
    and countless other things.

    The technology is so cool, just as long as you are in control. The way to get customers on board is give them a way to get control.

    Either that, or have Apple release iTag.

    hey look like bowed out triangles, squares, octagons, etc etc..

    Triangles, yes. Squares and octagons, no. Shapes with a constant diameter cannot be made from any regular polygon. They must have an odd number of sides so that the points on a side are a constant distance from the point of the opposite corner.

  9. Re:Manhole Covers on How Would You Move Mount Fuji? · · Score: 1

    Another is a equilateral triangular cover. There is no diagonal like there is in the square; no orientation that exploits a larger width than the triangle's sides.

    However there is an orientation that is shorter than the triangle's sides. The height of an equilateral triangle is only side*sqrt(3)/2 (about .87 * width). You could slide a triangular manhole cover down the manhole by making one edge vertical and the plane of the cover parallel to and just inside one edge of the hole.

  15. Re:And the problem is? on Office Depot: Windows XP Apps Must Be Microsoft-Approved · · Score: 1

    There is no problem, as long as Office Depot is making a free choice. Many posters are concerned that MS has the motive/opportunity/history to foist this rule upon Office Depot.

    Moreover, it seems that Office Depot, were it acting purely in its own interests, would not delegate its purchasing authority to a third party, but would continue to make decisions for itself - even if it ended up making the _SAME_ choices.

    This is something new, but most people are just missing the point.

  17. Re:idea gone? on Digital Movies, Analog Oscars · · Score: 1

    Fun!
    But I have a different take. I think that if an idea is written down, the writing is not itself the idea, but just a representation. When the idea is subsequently forgotten, it exists nowhere and is gone. The act of reading the representation, therefore remembering the idea, brings it back into existance. I guess my thesis is that ideas cannot exist outside our minds, although shadows and descriptions of them can.

    Of course, another tack could be to assert that my idea of X (M) is different from your idea of X (Y). This could imply that if M is forgotten, it is gone forever. You could read my description of X and create Y, but never M.

    Even further down the scale of impermanence - we could say that M changes of time. MsubsriptTODAY != MsubscriptTOMORROW. Then every idea, besides those held at this exact instant is both gone and forgottten.

    (I was a philosphy major, so you must forgive me -I never get a chance to use it.)

  19. Derivation of the equation on Pancake Physics to Cut Batter Splatter · · Score: 2, Interesting
    I have just had a bit of fun trying to derive the given equation. I came up with a result that is very very close.

    1) Hang-time of the pancake:
    • t=-2V/g

    2)Time for a 180 degree flip:
    • t=pi* pancakeRadius / (farEdgeVelocity-centerVelocity)

    3)Starting spin condition:
    • (farEdgeVelocity-centerVelocity)=angularVelocityAr m*pancakeRadius


    4) I can substitute equation 3 into 2 to get:
    • timeToFlip=pi* pancakeRadius/(angularVelocityArm*pancakeRadius)


    5) The pancake radius cancels out!
    • timeToFlip=pi/angularVelocityArm


    6)Then, I set the two times equal to eachother, because we are looking for the time to flip to be exactly the hang-time:
    • pi/angularVelocityArm=-2V/g


    7) Solve for angular velocity...
    • angularVelocityArm=pi*g/(-2V)


    8) The condition at Launch is :
    • angularVelocityArm=V / armRadius


    9) So, by 7 and 8, (substituting V)..
    • angularVelocityArm=pi*g/(-2* armRadius* angularVelocityArm)


    10) which is the same as ..
    • angularVelocityArm = sqrt ( pi*g/ (-2* armRadius) )


    This result is just a clean factor of two off from the article. I'm very suprised that I can put together enough physics to derive something that is apparently so newsworthy!

    now someone help me find the mistake!

  20. Re:Does anyone else see a flaw in this formula? on Pancake Physics to Cut Batter Splatter · · Score: 3, Insightful

    The problem seems to be in the interpretation of the english representation of the equation:

    The angular velocity of the object equals the square root of Pi, times the gravity divided by the distance the pancake is from the elbow times four

    You took this to be :

    (sqrt(pi)*1g)/(d*4)

    when it should be interpreted as:

    sqrt( pi*g / (d*4) )

    then you get the right units.

  21. Re:Why is this government-controlled? on Kid-Safe Domain Created · · Score: 1

    It seems so self-evident to me that a government enforced .porn TLD couldn't work, that perhaps I went to fast.

    If there is to be one standard, will it be the most restictive? If so, then we have to worry about what you and I would (and everyone but the most prudish individual) would call overly restrictive.

    Explain to me how a single black-list (which is what I take an "RBL" to be) can surmount these difficulties. The root problem is that there is no single standard.
    It's pretty easy when your examples are "barbie fisting", but the world is not always so black and white.

    So if it is "simple", to get "all isp's" to do something, you go right on ahead. I just think you may not have thought this through.

    About that "radical religeous right", it's not a term I ever used. But I do believe we have something to fear. Take a look at CHIP/CIPA/COPA to see what happens when even local libraries are tasked with setting a standard for internet pornography.

    Is that where I should go for information about contraceptives or to see pictures of Botticelli's "Venus"?
