    Widescreen doesn't necessarily cost scan lines. Almost all widescreen DVDs are encoded using an anamorphic squeeze. This means that the 16:9 picture is squeezed into the 4:3 frame. The DVD player can then determine whether to add letterbox bars for a 4:3 TV or send the signal directly to a 16:9 TV.

    Even if you don't have a widescreen TV or an HDTV there are plenty of Sony CRT based TVs that can squeeze the 480 scanlines into a 16:9 shape on the 4:3 tube and show the movie at full DVD resolution.

    What could be move distracting than amputated frames and obvious pans across the original material?

    Pick your poison.

    Back in the good ol' days of silver or gold backed currency the government placed controls on personal holdings and transport of those metals. It used to be ILLEGAL to stash physical gold ( see the Gold Confiscation Act of 1933). That law only changed in 1975, not that long ago.

    We may have "worthless" paper currency now but you are not restricted from holding silver and gold in your home or transporting it within and outside the US. You can always cash in your paycheck every week and buy ingots. I'd recommend holding some cash though for things like groceries and utility bills. You might be able to find a bank that will let you check against a balance held in gold though. That would solve your problem wouldn't it?

    Gold bugs sure are silly.

    I agree with your Apple comment. They are innovators with the special gift of creating solid new products.

  12. Re:In defense of The Grey Lady on NY Times Op-Ed Page Goes Subscriber-Only · · Score: 1

    Brooks and Safire are pretty different in style. I think of Brooks more as a considered commentator on conservatism, IE somewhat detached. That comes across more after you have seen his delivery on TV.

    Safire seemed more participatory in his commentary. I also found his political views more centrist, practical and libertarian (at least to my thinking).

    Last but not least calling Krugman a center-liberal is a little odd. Even Krugman happily embraces his full left-winger status. He takes shots at the right which a centrist might also but a full read of his writings clearly shows his liberal stripes. What I find disturbing is that his emotional connection to a subject often clouds his commentary on economic issues which deserve more professional handling from a distiguished MIT economist. It makes me think that his non-economic commentary is similiarly rabid. You may disagree with Brooks but you can't fault his considered style.

  13. Re:Diamond market will not collapse on A Step Toward the Diamond Age · · Score: 1

    In fact the most obvious characteristic of a jewelry grade, man-made diamond is its quality - its PERFECT. Natural stones have inclusions - ribbons of crystal defects, which the synthetic diamonds do not have. Of course the industrial process doesn't make a perfect stone - I'm talking about these emerging techniques.

    It will take some deft marketing by DeBeers to convince a woman to except a lower quality just because its "natural" With all the plastic surgery out there you'd think women were already convinced that science can make something more beautiful than nature intended ;^)

    In the end to comes down to DeBeers brilliant linking of expected engagement ring cost to the man's earning level, IE two months salary. The man is expected to put a large monetary investment into the marriage proposal to prove his dedication.

    Women want to receive a ring which signals this dedication, demonstates their future husband's earning potential and earns the envy of their girlfriends. It isn't romantic but that's the calculus underlying the whole transaction. Synthetic, flawless, cheap diamonds don't do those things and therefore won't be accepted into the tradition, at least not "officially"

    You bring up a good point: Programming languages and their interpretors, where applicable, need to be MT safe and they often aren't.

    A large matrix calculation is the perfect place for two processors to work on a problem, but if you ned to copy memory back and forth it loses a lot of efficiency. If you pass a pointer to save time you have created a sync problem.

  16. Re:You are completely right! on AMD's Dual-core Athlon 64 X2 reviewed · · Score: 1

    That is exactly what I meant. Synchronization is a tricky issue but I'd consider it far more rare than the problem of cycle hogging single-threaded apps.

    I'm not professional programmer and my hobby style projects have all been single threaded. That said, if my multi-threaded app performed poorly on a dual processor system I'd consider the good single processor performance to be a fluke more than anything. Threads cease to be threads when you need to worry about their low level interactions. The abstraction and communication protocol should be all that is necessary for hardware, OS and app to work nicely with threads.

    In most programming environments I'd expect the operating system to handle the allocation of threads to processors and for the secondary threads to have an asynchronos relationship with the master thread anyway. I'm sure the details can get tricky - they usually do.

  17. Re:this is a software problem... on AMD's Dual-core Athlon 64 X2 reviewed · · Score: 2, Interesting

    Apps that are written with multiple threads are typically also written with care to avoid locking up the computer.

    Single threaded apps are typically written with far less care and don't leave cycles free for the GUI and OS functions.

    That is why having the second processor is nice. It has free cycles when an app is hogging the other one. A multi-threaded app will use both but will probably not hog both, leaving the GUI still "snapppy".

    Those countries don't harbor terrorists like Afghanistan and would likely help us capture him. Denmark and Brazil would HELP us capture him.

    A captured high level Bin Ladin associated said that the Taliban warlords were reluctant to endorse his 9/11 plans because they were worried about taking heat from the US. Note two things - firstly they knew about the attack and endorsed it; second, that they appreciated the consequences to their rule.

    If terrorists were coming out of Brazil we would give the Brazilian government some time to clamp down on it. If they failed we would go in - guns blazing. What else would you think? Look at what the US did in Central America in the 80s, and that was just Cold War/Drug War stuff.

    If the "Greek guy" in your thought experiment had gotten permission from the US Congress to carry out the attack I wouldn't be surprised at all if Brazil attempted to retaliate.

    And about training camps in the US.... ever heard of Ruby Ridge? Our government isn't shy about shutting down "camps" anywhere they might exist.

    The parent has a good point. It is still called the "Theory of Gravity" (Or Gravitation). That doesn't mean, on a practical level, that anyone thinks the earth will stop orbiting the sun or that jumping of a tall building will result in anything but a quick trip to the morgue.

    Air conditioning is indeed one element for which demand matches solar output very well.

    1, 2, and 3 are all true and yet people still don't use solar panels as often as you would guess.

    Solar power systems still need a huge amount of batteries or a grid connection. Most people don't want to put in the effort. Perhaps if everyone paid 15-16 cents/kwh like I do that would change.

  25. Re:Taking care of some things in one post. on Breakthrough in solar photovoltaics · · Score: 1

    Maybe I was unclear but we are agreeing on coal. It is really cheap and much more profitable than natural gas most of the time.

    The demand curve isn't totally different then the solar supply curve through the day, unless of course it's raining and the PVs are producing zero electricity.

    That brings us to the solution to both storage and solar output variability - tie the panels to the grid. Well how do we power the grid then? If end users have no energy storage then power plants and transmission lines will need to sized assuming no contribution by the PVs. Certainly there will be cloudy days with near peak energy consumption won't there?

    Grid tied systems only work for the consumer because the meter runs backwards at the consumer rate. After costs and transmission losses the power company loses a lot of money. If most customers ran PV systems on reverse meters the cost of power would have to rise significantly.

    We are up to date on the competition. All the studies in the world don't necessarily add up to anything more then tenure for an academic. I wish ultra cheap, efficient PVs were all it took, but the problems are just so much bigger then getting 24 volts DC out of some panels when the sun happens to be shining.

    As an aside I think thermal solar systems using concentrators looks far more promising. YMMV
