    You know what the difference between a telescope and a mortar is? The stuff inside the tube.

    If you're in a warzone, checking up on a group of people setting up a tube on a tripod is a perfectly reasonable thing to do.

  2. Re:Uh. So? on Banks Find Way To Sell Consumers' Shopping Data · · Score: 2

    I fail to see any issue with this. The bank that owns my credit card has a list of the transactions I've made on it. And they are now going to send me spam targeting me based on those transactions. The bank has always had the information. The bank still has it. There is no privacy issue here.

    Let's say I want to know who in your town has purchased pornographic videos. I go to the bank with a "buy one get one free" deal for my pizza parlor and have them send it to everyone who's purchased one or more porn videos. As people redeem those coupons, I build up a pretty good idea of who's watching movies they'd rather I didn't know about.

    I can repeat this sort of thing with different deals and different criteria, and get a pretty good idea of what sort of information the bank has. Since the bank is kindly hiding the link between my coupons and your habits, you don't have any idea that I'm doing this.

    Give it some time and they'll be as commonplace and unremarkable as anything else on the road.

    Doesn't mean they'll know how to use the thing, though.

    As written in the law: Vehicles entering the roundabout yield to vehicles in the roundabout, you signal your exit by activating your right-hand turn signal when approaching your exit.

    As practiced by drivers: Vehicles in the roundabout are expected to yield to vehicles entering the roundabout, your choice of exit is indicated by which signal you activate before entering: "right" for the first exit to the right, "left" for the third exit, "neither" for the second exit.

    In the US, I turned right out of the DMV onto a 30mph road, turned first right, turned first right, turned first right, turned first right, and then turned back into the DMV. I had already passed the "written" part of the test (really, multiple choice. One question was 'what does this sign mean?'. It was a STOP sign...). That was it. Apparently that's all you need to drive one of the massive honking SUV's they have out here at 100^W 65(hah!) mph on the freeway. It does explain a lot about the (apallingly-bad) standards of driving out here though.

    My first driver's test covered everything from basic handling to things like merging onto highways, dealing with (simulated) railroad crossings, and reacting to emergency vehicles (not simulated: there really was a firetruck coming up from behind). No roundabouts -- to the best of my knowledge, the nearest one was a little over 500 miles away.

    I've heard that the test for established drivers is about as you describe: if you've got a clean driving record, it's mostly a formality, and partly a way to filter out the occasional older driver who just doesn't know when to quit.

  10. Re:Bitcoin on Ask Amir Taaki About Bitcoin · · Score: 1

    Inflation: I have excess money right now. I know it will be worth less in the future, so my best option is to turn it into a non-monetary form: either purchase something I will need in the future, or invest it somewhere.

    Deflation: I have excess money right now. I know it will be worth more in the future, so my best option is to store it under my mattress until such time as I have a pressing need to spend it.

    There are two problems with deflation, both stemming from the above. The first is that unlike prices, wages don't deflate cleanly: instead of giving annual paycuts, wages deflate by companies laying off the highest-paid workers and hiring cheaper ones. The fact that wages tend to deflate ahead of prices doesn't help. The second is that wealthy people stop investing and start saving, which causes the economy to stagnate: companies have trouble getting the money they need to grow.

  12. Re:On the upside on Final Attempts To Contact Mars Spirit Rover Fail · · Score: 1

    Martian winds are nowhere near strong enough to move the rover -- because of the low pressure, even the strongest winds would be just barely perceptible to a human.

    Over the short run (hundreds of years), burying is unlikely: there's nothing near Spirit that's a good enough windbreak to generate a drift covering the rover. The rover will generate its own downwind drifts, but in the short run, those will simply make it easier to find the rover. Over longer terms, it's quite possible that a more distant feature will generate a drift covering Spirit.

    I do think that Nintendo should consider going USB for media sales though. The cost of a USB stick that can compare to a DVD is size is a small fraction of the cost of the game, so the cost factor that lead to optical media is less of an issue.

  17. Re:No reason to buy on Nintendo Chief: Consumers Don't Understand 3DS Yet · · Score: 1

    I don't have stereo vision normally but it works with the 3DS (and any other 3D system that I've tried that works by showing different pictures to each eye). I'm not sure how exactly that works, but it makes the 3DS even more attractive for me and less of a gimmick

    I've encountered people with that issue before, when I ran my university's virtual reality lab. There are about a dozen different cues the brain uses to judge depth; my guess is that by suppressing one of the major ones (accommodation, ie. focal depth) and emphasizing one of the minor ones (stereopsis), it avoids whatever's causing you to have trouble seeing 3D.

    (Incidentally, this same combination of suppressing accommodation and emphasizing stereopsis is why many people get headaches from current 3D systems.)

    There have been studies that show a huge increase in collision, especially rear-end collisions at intersection cameras.

    There's a tradeoff involved with red-light cameras: they increase rear-end collisions, which have a low injury rate, but decrease T-bone collisions, which often result in major injury or death. Total collision rate at the intersection goes up, but the injury and death rate goes down.
