    Sure any factorization (over the integers) is unique, but the primes may not be. Of course, challenging people to factor a perfect square would have been incredibly stupid.

    Calling the Mormons not "christian-orthodox" is not the same as saying they are not Christian. Considering that they are a minority with significantly different views than the majority of Christians, I think it's quite appropriate.

    Nor were they called "wacko", that was a reference to MoG's attitude towards the Jehovah's Witnesses, who are also not exactly "christian-orthodox". I don't think gowen was endorsing the term being used against either religion.

    "...intel has been making bad decisions for a while."

    Very true, but you didn't go back far enough. Remember how the Z80 almost took over the entire 8080 system market because Intel got complacent? Or how about the IAPX-432, that was supposed to be the new micro server platform?

    Intel has so far always managed to overcome its mistakes and crush its competition. I think it's too early to say that this time will be different.

    It's hard to answer your questions because most of your suppositions are wrong. For instance, the crust of Mars is mostly silicates, just like Earth's.

    You need to either go to a local library and check out a book on elementary planetary science or, if you have decent web access, look at some basic astronomy sites. A quick search with Google yields, for example http://spaceinfo.jaxa.jp/note/tansa/e/tan105_mars_ e.html.

    A good place to start is wikipedia. For Mars, that would be http://en.wikipedia.org/wiki/Mars_(planet).

    Those may or may not be the best sites for you, but look around, there is a lot of information available.

    That doesn't catch my grammar mistakes, but it makes my posts a little less embarrassing.

    AMD has been selling low power server chips for awhile, so they have the ability to power bin their chips. Now if I was AMD and Lost Circuits wanted to test the power consumption of the new Venice core, I'd run a hundred chips through the power tester and send them the lowest power one.

    This assumes the part was a sample provided by AMD, but this is the usual case as I understand it.

  15. Re:When? on Image Preservation Through Open Documentation · · Score: 1

    One way to look at how much resolution you need is to see how much you can output.

    Usually 300 full color dots per inch is considered about all you could need. This is about what you get from a dye sublimation printer. Do not confuse these 300 dpi with the specs of ink jet printers, whose dots are not individually full color.

    For an 8x10" print, full resolution output would be 8*10*300*300 dots, which is 7.2 million dots. For a 4x6" it's a bit over two million dots.

    The individual sensors on digital cameras are usually monochrome, so it takes more of them to create a full resolution print. A reasonable estimate is it takes twice as many, so you need about 14 megapixels for a full resolution 8x10" printout, and four megapixels for a 4x6".

    This is as much resolution as most people can hope to print, quite a bit less will still look good. More resolution can be useful for cropping, so getting a 5 megapixel camera can still be a good idea even if all you want is 4x6" prints.

  17. Re:Exactly... on DMCA Prevents Photoshop Support of Nikon Camera · · Score: 1

    On high end consumer cameras (sub SLR), Nikon usually gets better reviews for its lenses than Canon. The Canon lenses seem to have more chromatic aberration. Overall, though, the Canon cameras get better reviews.

    On the cheap SLR front, the kit lens for the Nikon D70 is supposed to be much better than the one for the Canon 300D. The D70 kit lens does cost a lot more, but it seems that Nikon is not as comfortable as Canon in selling lower quality lenses for their cheaper cameras.

    Nikon charging extra for full raw image support was one of the reasons I bought a Canon S70 for myself.

  18. Re:It isn't just downloads.... on Canadians May Face 25% Download Tariff · · Score: 2, Insightful

    You're just ignorant, although that's not surprising considering how little coverage the softwood timber tariffs get here in our beloved United States of America.

    Basically, the US has imposed the tariffs because we say Canada is giving illegal subsides to its timber industry. Outside observers, including the WTO, side with Canada in saying the tariffs are unjust. The American timber industry has a strong lobbying organization, which may have an influence on our trade stance.

    This is all very similar to the steel tariffs that were eventually rescinded. I suspect the main reason the steel fees went away and the lumber ones didn't is that the steel consumers (e.g. autos) were able to mount an effective political protest, whereas lumber consumers (e.g. home builders) are unable to do the same.

    I have no idea how much aluminum is replacing wood in buildings, but if the wood prices were where they should be it wouldn't be as much. So perhaps the aluminum industry has joined the lumber industry in lobbying for the tariffs.

  19. Re:No - we're doomed. on Sea Life Wiped Out by Neutron Star Collision? · · Score: 1

    The mechanism proposed for the wiping out of the ozone layer is by the production of oxides of nitrogen. The gamma rays hit the upper atmosphere, split nitrogen molecules in to atoms, which then combine with oxygen. The nitrogen oxides pretty much destroy the ozone catalytically, just like the chlorine in chlorofluorocarbons, only they last years instead of decades.

    Winds disperse the nitrogen oxides around the world, destroying much more than half the ozone layer for several years, which may be long enough to wreak our ecosystem from the increased ultraviolet radiation let through.

    I would guess some people would survive this, but it might destroy civilization.

    No, dummy, it's not centripetal force. That pulls the elevator down: I'm talking about why you need to pull down to keep it in place.

    Now, in an inertial reference frame, what I was talking about was the inertia of the elevator. If we translate that to a rotating frame of reference it becomes centrifugal force. We don't do calculations that way, because it's harder, but it is a perfectly valid way of looking at things, despite what your high school physics teacher said.

    A space elevator in free orbit will pretty much just sit there, even if it's not tethered.

    If you try to use the elevator that way, each load you send up will change its orbit, and also tend to make it spin. That's why once the elevator is attached to the Earth, you want to move its center of mass just outside of geosynch orbit to add some extra tension to the cable. This makes the elevator dynamically stable, and transfers the impulses from using it to the Earth.

  22. Re:Call me a nay-sayer... on Space Elevator Update · · Score: 2, Informative

    The energy comes from the effort you put into climbing the cable, but I think what's really bothering you is the question of where the momentum comes from.

    The momentum comes from the Earth, which is slowed down by an imperceptible amount when the cable is climbed. This transfer is through the cable, which is held in tension by its rotation with the Earth ("centrifugal" force). In climbing, the cable is bowed slightly, which causes the cable to tug on the Earth.
