  1. Re:OH GOD on Microsoft Responds to 'Save XP' Petition · · Score: 5, Informative

    That's because Halo 2 doesn't actually need directx10. It has a 'is this vista check', and it might use a couple of minor new directx 10 direct3d calls (which can easily be captured and reimplemented in direct3d 9).

    Correct. A lot of the rest, well, not so much. And I appologize in advance for tearing into you over this, but I do 3D graphics programming for a living and it just pisses me off to no end how MS's marketing statements have somehow morphed into technical truths when they are clearly not true at all.

    In a nut shell, DX10's rendering features can be (and are, under OpenGL) implemented under the old driver model. Vista's shiny 3D desktop and ridiculous DRM (which are separate from Direct3D 10), however, cannot. Microsoft consistently choses to confuse the two, but they are distinct technologies that shouldn't probably don't rely on each other to any significant degree. Details follow.

    The real features of directX10 like Video memory virtualization and gpu multitasking (which allows Vista to have multiple direct3d accelerated applications (including the desktop) all running at the same time in (possibibly overlapping windows).

    This is all possible on XP with both OpenGL and Direct3D 9. Seriously, get a couple of 3D programs that run in windowed mode and drag them around your monitor. Overlap them. It works fine on XP. Managing the GPU resources is simply done inside the driver. All Vista's model does is move some functionality that used to be common to all drivers up into the kernel, because refactoring things this way allowed them to remove some of the overhead from most D3D API entry points - overhead that exists in D3D 9 (which is obviously not crippled or useless because of it).

    The D3D10 feature set could be implemented in XP without rewriting the kernel. There might be more overhead when calling rendering functions, but it probably wouldn't be worse than calling D3D9 functions (and D3D9's API is a lot chattier than D3D10's). There is no D3D10 feature that requires the Vista kernel rewrite.

    If you don't believe me then go put a GeForce 8 series card in a XP machine, install the latest driver, and then download GLEW. Get it to dump out a list of available OpenGL extensions (visualinfo.exe in the bin directory, assuming you downloaded the Win32 binaries). Note these extensions in particular: GL_EXT_geometry_shader4, GL_EXT_texture_array, GL_NV_transform_feedback, as well as a few others I don't care to list. Those are all the OpenGL equivalents to the new D3D10 feature set. If NVIDIA can expose D3D10 generation features through OpenGL on an XP driver running on the old XP kernel, Microsoft can do the same thing through Direct3D 10. They simply choose not to.

    The only thing the old driver model can't actually do is share graphics resources among multiple processes, something that pretty much no 3D graphics application would ever really do in the first place (because launching processes and getting them to talk to each other is really expensive on Windows), and something which is not required for useful D3D 10 support. Read on to find out why they stuck in a useless feature.

    You aren't going to get a proper Compiz or Aqua class desktop for XP because XP simply can't do this stuff. Vista/DirectX10 can.

    The shiny 3D desktop thing in Vista is the only thing that really requires the new driver model, as it is what actually makes use of the ability to share D3D resources among multiple processes (it basically shares any 3D app's render surface into its own texture set). And note that the shiny desktop doesn't even use D3D10. It just uses D3D9 plus the extensions to D3D9 that are only available under the new driver model - extensions which only serve to notify applications that their device will (almost) never be lost (mundane window/D3D device setup thing, has nothing to do with actually rendering) and expose th

    Yet obviously this country has already spent a lot of time under a gold standard, and it's very easy to verify that during this time inflation was about the same as it is now or slightly worse, and the boom-and-bust cycle was considerably worse. It's really easy to google for graphs of these things, it's not some obscure data.

    Yes, and most of that data is from the last century and doesn't account for things like the current level of industrialization, advances in medicine, overall exucation, etc, etc. I mean, really, if we're gonna whip out the charts then why don't we talk about the bust that hit around the 1930's, you know, the only one that the average person knows by name? It happened very shortly after the current system was introduced...

    Too many variables have changed over the last hundred years for any such analysis to be even remotely scientific.

    If you want to argue that commodity backed money is bad, try this: commodity values are severely dependent on political and economic structures that extend far beyond any one nation's control. That's why I'd be against a gold standard, and it's a much more rational way to argue than comparing pre and post Fed economic charts when almost everything else has also changed.

    When the government spends more than it takes in, the treasury department sells bonds.

    Wikipedia says (emphasis mind):

    When the expenses of the U.S. Government exceed the revenue collected, it issues new debt to cover the deficit. This debt typically takes the form of new issues of government bonds which are sold on the open market. However, the debt can also be monetized by which the Federal Reserve creates an entry on its books to credit the US Government for an amount equal to the dollar amount of the bonds the Federal Reserve is acquiring. The money created in this process not only includes the new dollars that came into existence just to purchase the bonds, but much more because this new money is now sitting in the form of checkbook money at the Federal Reserve. Under the scheme of Fractional Reserve Banking this new checkbook money is treated as an asset to lend against. Economists estimate the expansion of the money supply as being many times the amount of the initial money created with the exact amount being a function of what percentage of deposits banks must set aside as "reserves".

    Even if that's overblown, you still have this to deal with (from the same article):

    A traditional defense of the national debt is that we "owe the debt to ourselves", but that is increasingly not true. The US debt in the hands of foreign governments is 25% of the total, virtually double the 1988 figure of 13%. Despite the declining willingness of foreign investors to continue investing in dollar denominated instruments as the US Dollar has fallen in 2007, the U.S. Treasury statistics indicate that, at the end of 2006, foreigners held 44% of federal debt held by the public. About 66% of that 44% was held by the central banks of other countries, in particular the central banks of Japan and China.

    How, exactly, does selling treasury bonds to foreigners (like, say, the Chinese) offset the new dollars circulating in the US economy? I mean, yes, you could say "well, they would have otherwise spent that money into our economy", but you don't know that for sure. And anyway, that's exactly what selling them the bond does, as it allows the government to create and use more money, which is then amplified by the fractional reserve banking system. That money won't be removed from the system until much later, and at that time it's likely to be repaid by simply issuing bonds elsewhere.

    Yes, the gold standard is the wrong answer. So is unfettered and irresponsible government spending. And it's just stupid to ignore the fact that this causes inflation which does hurt everyone but the military and the
