    No, of the 7, those 2 conditions can be reduced to a triplet not a 6th binary pair. That leaves 5 binary pairs and the triplet.

  2. Re:Perhaps this explains my Garmin on GPS Always Overestimates Distances (i-programmer.info) · · Score: 1

    If you are running on a track your Garmin watch is accurate enough to underreport when worn on your inside wrist and overreport when worn on your outside wrist.

    If you are running on a track and the polling frequency of your GPS is too low (not a factor with my Garmin) you also get the problem of underreporting due to chording the curve.

    So, let's allow passengers with concealed weapons permits to carry on board.

    Seems very counterproductive. US deaths due to accidental firearm discharges are higher than US deaths due to terrorism.

    That's handwaving, for if you know a way to reliably detect small submarines which are attempting to be stealthy you've solved a far larger problem than this one.

    I'm on-board with Military funding to thwart this - let's fund the military and have them lay down 200 redundant cables. It's absurd how few of these we have.

    2 cables or 200, it doesn't matter when talking about exposure to intentional sabotage by a state actor. Destruction of such assets is inherently asymmetric.

    Right. Ignoring the fact I was wrong and she was averaging more like 6 books a day, the fact remains that suspicions and charges of fraud are reasonable.

    Accusing someone of a fake review is not the same as accusing them of fraud.

    How is it not? She financially benefited from writing fake reviews while claiming they were real. She violated multiple Amazon terms of service to receive compensation.

    and outright accusing them of fraud simply from the act of posting consumer reviews to an e-commerce site.

    She averaged, what?, three book reviews a day, for years. Mostly new books too, it isn't like she was sitting in front of her computer writing reviews for books she had read decades before.

    Unless you're suggesting she actually read all of those books the fraud accusation is just, and unless you knew her personally to have read all of those books the suspicion of fraud is reasonable

  9. Re:Physical store advantage? on Walmart Plays Catch-Up With Amazon · · Score: 1

    Yes, Walmart has a huge and efficient distribution system, but can they really leverage that for online sales? When stocking stores, they ship large quantities to each store. For online sales, it's small quantities of a much larger variety. You have to support the customer who is the only one in the area buying that item just as well as you do the customer who buys the most popular item. I doubt their distribution system can adapt to that model.

    What you're missing with this line of thought is the proper comparison.

    Walmart's huge and efficient distribution system, which you rightfully point out is efficient at moving large quantities, is not competition for the Amazon business model.

    It is competition for the Amazon + UPS/USPS business model.

    WalMart can leverage their back end to get products very close to customers very cheaply. They then simply need to solve the last (5) mile(s) problem. Amazon relies on external companies (UPS/USPS/FedEx) to do this and while they are creating same-day delivery infrastructure in-house in major metropolitan areas they have nowhere near the population coverage WalMart already has.

    First of all, rotors don't "warp" in the sense that you're implying. Vibrations from a "warped" rotor aren't from deformed metal, its from uneven brake pad material deposits that can come from improper bedding procedures or operation outside of ideal operating temperatures.

    Just about every one of your claims about how GPS (and SA) works are wrong.

    The Saudis are forcing OPEC to keep producing oil because they have the cash reserves to operate at a loss for a good while and are trying to drive the US oil producers-who rely on fracking-out of business. The problem with that strategy is that fracking is becoming more efficient, which lowers the break-even point. Basically the Saudis are playing the long game in order to try and shore up their monopoly status.

    That's 2007 thinking, and likely incorrect.

    1 - The Saudis have already lost the battle to prevent US frackers from drilling. Even if no new wells are drilled and nobody touches the significant fracklog of drilled-but-not-fracked wells there is more than enough surplus production to last through 2020 when:

    2 - The Saudis don't have enough cash reserves to hold out more than ~5 years at current spending levels and $60 bbl oil. At current prices (and look at the futures market) they're going to run dry early.

    http://www.telegraph.co.uk/fin...

    And note how futures prices have decreased even more since.

    http://www.cmegroup.com/tradin...

    Thus they are not playing the "long game" they are playing a very very "short game" of "spend on the military so the ruling class doesn't get beheaded and hope we can hold on".

    It makes sense this can be flooded

    Flooding is very possible.

    - just pick up the signal and send it back amplified, and it seems there's something really close.

    But what you're describing there is impossible. By the time the light reaches you, the attacker, it is too late to create a false target which appears closer than you (assuming a time-detect lidar system). An attack must presuppose and be delivered before the target pulses are sent from the transmitter.

    I assume at least they're looking for brightness rather than timing (distance travelled is very short and light is very fast) to determine the distance of an object.
