  1. Re:This again? on Toyota Partners With Tesla To Make Electric Cars · · Score: 1

    The problem with that overly narrow analysis is that gasoline-powered cars produce exhaust that clings to the ground in heavily populated areas that are often down in a valley, whereas coal-electric cars produce exhaust that clings to the ground and spreads out near a coal plant that is probably out in the middle of an unpopulated salt flat. Sure, if your only concern is the environment as a whole, that doesn't make any difference, but if you're looking at it from a human health perspective, the EVs are much, much, much cleaner.

    True, and this being Wi-Fi, that's a very real problem. I was thinking more of wired ethernet when I made that comment. This is one reason why for high density Wi-Fi coverage areas, you should generally reduce the transmit power to limit the range of the radio and use more radios.

    It's pretty much a given that there's prior art. It's a patent on a server dynamically generating markup. They filed a patent in 2002 for what amounts to a basic template-driven C-based CGI script similar to the ones I and thousands of other people were writing way back in the 1990s.

    Now granted, I couldn't find any online way to view the full patent text, so there might be something more to it, but from the way the ruling describes it, I'd be surprised if nobody else had done something similar more than a decade before that patent application.

    Heck, if the court's interpretation of what the patent covers is correct, the patent would be violated by Gopher/WAIS. The ANSI standard behind that dates back to the 1970s.

    This patent is beyond laughable.

    I'm assuming you would agree that movies depicting gang killings are expression, right? Take West Side Story, for example. What about movies that are depictions of actual gang killings, e.g. Freedom Writers? As soon as you get into dramatizations of real-life murders, the line rapidly blurs. So as long as the actual dead body isn't shown, you're okay with it. But what about photos of DUI victims in MADD videos? Is that okay? If so, how is that different? If not, how is that not expression?

    At what point do depictions of murder victims become "not okay"? There really isn't a clear line. What makes child porn special is that it causes irreparable psychological harm to the (still-living) victim, and that's why disseminating it is illegal. This, of course, assumes that there is an actual child victim. In cases where it is faked (either through adult actors/actresses or through CGI), that's a much harder argument to make.

    Just a demonstration of why the most important thing about data preservation is choosing the right technology: I went to Wendy's last week and found out the hard way that they use thermal paper to print their receipts. By the time I got to where you're going, the heat from the food had turned my receipt into a charcoal-grey blob with indistinct writing....

    Acid-free paper goes a long way, but ultimately they need to put acid-free paper maps TO the vault all over the place, paint them on sides of buildings, etc. so that if civilization collapses, somebody millennia from now will be able to find the vault. Either that or they need to bury it near a population center so that people will actually be LOOKING for it. This, of course, assumes that they expect civilization to collapse. If they don't, then there's really no point to doing any of this.

    It's not like we can't find hardware to read legacy digital media from the late 1970s or early 1980s on. The reason it's hard to find stuff before that is because A. stuff wasn't standardized before that point, and B. it wasn't prevalent enough. Thus, out of the triple-digit instances of a particular model of mainframe tape drive, a single-digit number of them might still be functional, and that single-digit number might be zero. When you have hardware that was built in the millions of units, this is not nearly as common a problem. Also, now that data formats have largely converged to a set of broadly deployed standards, chances are, any records of value are periodically carried forward to newer hardware anyway, making this largely moot. The exceptions are mostly government jobs. :-)

Now if they admit to another crime, then they should be tried for that second crime, and if convicted, sentenced to a longer term. Otherwise, anything else is a rather blatant violation of two different parts of the fifth amendment---the right to a trial by your peers (being held indefinitely without a new trial), and double jeopardy (having your sentence changed outside the deliberately limited scope of an appeal under 18 U.S.C. 3742(b)).

    Who cares? Radiation exposure is cumulative. And high altitude flying is basically unavoidable; these stupid little machines aren't.

    Saying that it doesn't matter because you're exposed to more of it in your daily life is like saying that picking up a possibly-loaded revolver, putting it up to your head, spinning the cylinder, and pulling the trigger on Cinco de Mayo is not dangerous because people are shooting guns up in the air anyway and one of those bullets might hit you. What matters is not the million times that the unavoidable background radiation misses everything and causes no irreparable damage. What matters is the one time that the radiation does cause damage. Thus, unnecessarily increasing that risk is stupidity, pure and simple, no matter how little you might be increasing it.

    Deliberate ionizing radiation exposure should NEVER be allowed for non-medical purposes, and even then, should be targeted to a single area of the body, not spread across your entire person.

  24. Re:But no one cares about cosmic ray exposure... on Scientists Question Safety of New Airport Scanners · · Score: 2, Interesting

    Quit exaggerating. The background radiation level doubles every 6,000 feet, so an entire 24-hour day at 30,000 feet is like a month on the ground. A four hour flight is roughly the equivalent of 5 days on the ground.

    Also, remember that radiation exposure is considered cumulative. There is no safe level of radiation exposure. The more you are exposed to, the greater your risk of death, period. Thus, it is utterly irrelevant whether the backscatter machine only adds... say a tenth as much radiation as the rest of the flight. That's still 10% more than you would have gotten otherwise. (And yes, I pulled that number out of thin air solely for example purposes.)

    Besides, if you need to get somewhere quickly, the radiation absorbed while flying is an unavoidable risk. The radiation from backscatter machines isn't. It's like the worry about CT scans. Do they increase cancer risk? Yes. Are they sometimes medically necessary? Also yes. So the risk outweighs the damage when they are medically necessary, but nobody in their right minds would argue that everyone admitted to the hospital should get a full-body CT scan just in case one of them has something wrong. (I know we're talking about several orders of magnitude difference in dosage here, but the principle is still the same.)

    No, that's millimeter wave, which is the other type of full body scanner. Both backscatter X-ray and millimeter wave scanners cause cancer, they just do it in different ways.

    Either way, you won't see me setting foot anywhere NEAR one of those scanners. If enough people demand to be hand searched that it brings air travel to a grinding halt, maybe this bullshit will stop.
