    With A3D, a physical model of the environment must be constructed just as with normal visual 3D models in the application. This allows for accurate 3D sounds as the sounds are essentially "rendered" in the environment according to acoustic physics. Hence, reflections off walls that are closer will sound different than reflections that occur further away. EAX, on the other hand, only simulates the effects of environments using real-time effects such as reverberations.

    A3D required you to actually construct a 3D model so that the reverb, sound occlusions, etc were actually calculated for that environment. If there was a column between you and the sound source, it would be muted as in the real world. If you were just inside the mouth of a tunnel, your footsteps would reverb but someone yelling at you from outside the tunnel would not reverb since the sound traveled directly to you and not from wall reflections. Neat stuff.

    With EAX, Walking into a tunnel would cause an abrupt change in sound qualities, (adding reverb, etc) at the threshold of a tunnel, because the programmer would mark that area as needing reverb. This has been masked over with newer EAX versions, (3.0 by merging the two regions, smoothing over the change) but the system is still only doing what the programmer thinks it should at that spot. Hold a watch to your ear while in the tunnel and the ticking would have reverb even though it shouldn't. There is no accurate 3D rendering of environmental sounds.

    To use a visual metaphore, A3D was like Quake 3 and EAX is like Wolfenstein-3D.

    EAX 4.0 is like Wolfenstein-3D with photorealistic textures.

    Rising slowly is to prevent bubbles from forming in the blood (for air breathers) or from the gas bag bursting (gas bladder fish). The Giant Squid does not breath air or have a gas bladder. It suffuses its tissue with ammonia to make itself buoyant, So I'm guessing that rising quickly wouldn't be a problem.

    What kills them at the surface is the warmer temperature. Giant Squid blood sucks at carrying oxygen at higher temeratures. If they are too big, they will eventually suffercate in temperate water. The Surface area to volume ratio will only allow the much younger/smaller ones to live near the surface.

    Note also that they said the chunk of tentacle that was ripped off the photographed squid was still gripping the boats deck and even fingers when it was prodded.

    It could very well be that the Squid seen attached to the Sperm whale was still cold enough to fight (if brought up fast enough) and even as it began to die, it's tentacles would continue holding on for a while.

    I didn't know the formula for Gasoline of the top of my head so I just went to howstuffworks and used the formula there.

    "Gasoline is made up of carbon chains of different lengths ranging from C7H16 through C11H24"

    I picked c11h24 so the math would be slightly in his favor. I dont think it affects the point much anyways.

    Okay, I hate pissing contests but I'm pretty sure this is right.

    With a perfect burn, Each single molecule of gas (c11h24) must be given 18 molecules of Oxygen and assuming a simple 1/4 ratio of oxygen to nitrogen (ignoring the 1% trace gas) This gives

    I'm not sure what volume a liquid c11h24 so let me give you the benefit of the doubt and assume its zero. (This is in your favor)

    c11h24 + 18o2+ 64n2 (82 molecules of gas)

    After the burn it would be:

    12h2o + 12co2 + 64n2 (88 molecules of gas)

    So we get an increase of pressure of a 7% from byproducts from the burn of a single molecule of gas.

    But if we look at temperature the flame itself, 2,500 kelvin (open air). Given an original temperature of say 300 kelvin, and the formula you mentioned (pV=nRT). The pressure would go up 833% by Temperature alone.

    So I'll let you decide it. Byproducts (7%) or temperature (833%).

    btw, we don't use electric coils because we need a source of energy to power those coils. Such as the energy contained in gasoline. And that's why "we don't do this".

    Not a troll.

    The power stroke gets its strength from expanding gases. In a pure burn the expansion is done by temperature alone. With the water injection, it is combined with the phase change of water to steam, which lowers the temperature a bit but maintains or even increases pressure.

    The hydrogen ignites first, igniting the fuel air mixture more quickly and uniformly. That is where the net increase in power and efficiency come from.

    This makes sense!

    I used to have a Honda Prelude with the CVCC Engine. Compound Vortex Controlled Combustion. The engine ran so lean that the air/fuel charge could not be ignited with a normal spark plug. So it contained a small secondary chamber that was also lean but rich enough to ignite properly. The flame front from this small charge was swirled with the rest to achieve ignition in the "too lean" mixture.

    Neat tech..

    If I remember right, their are couple of ways the water injection helps. First, it evaporates a bit thus cooling the air so that a larger mass is pulled in during the intake stroke (depends on ambient humidity). Any mist not yet evaporated will increase the power by turning to steam during the power stroke. The phase change of the water to steam also keeps the powerstroke cooler than it otherwise would have been. Good for engine longevity and I think it also reduces NOX emissions.

    No references, just reguritating what I remember.

    Conspiricy theory? Retarded Children? Apocalyptic endgame blabber? Where did this come from?

    Besides I thought I did address your original question. I gave you a rational reason for MS to hold off on Software Patent pressure.

    Maybe you play chess? Understand this, You need to move the peices a bit before claiming Check Mate. Or are you so enamored by Bill Gates or disillusioned by RMS that you believe that since MS hasn't declared "check" that they are not playing the game to win?

    Or maybe you so savy that you know something we don't? That MS has only has the warmest and most loving feelings towards open source? Are you an Economist? Visionary? Soothsayer? When MS pays attention to you, you either get absorbed or destroyed. Maybe you can show us otherwise? But what you call FUD, I call History.

    You say talk about things they actually do? How about crushing the competition by any means necessary. I'd believe even the most devout MS fanboy would have to admit to the predatory nature of Microsoft, or maybe you would just prefer to hold your hands to your ears and yell "Na Na Na!" until finally through the miracle of denial, the sheep can truley sleep peacefully with the lions.

    I hate to break it to you, but that myopic view of nirvana doesn't mesh with reality.

    Let me teach you how the world works, It's really quite simple. The world is driven by Greed with a capital "G". IBM doesn't love OpenSource, but they encourage it whole heartedly because they make money from it. As long as thats true we have nothing to fear from them or their patent portfolio because IBM loves money.

    MS also loves money, but unfortunately MS only loses money from OpenSource. Make no mistake, we are their only true competitor left standing. Their shody products look bad in comparison and can't compete in price for the few products that actually shine. Because of that, and to protect their precious monopoly, MS will do anything it can to control or extinguish OpenSource. This is not being Evil, it is simply a business strategy.

    Software Patents, DMCA, TCPA, Palladium.. These are only chess peices being positioned for battle. It's not hard to see the goal. Opensource is a rogue element, a wild cannon. It needs to be controlled so that the IT field can be pinned down and milked for the maximum profit. How far do you think Microsoft will go to get more control so that they can make more profit?

    The competitor MS cares about the most is OpenSource and GPL. But that war will wait until Software patents are ratified in the EU, China, etc.

    The issue of Software patents is a touchy one, and MS is desparate to have it approved. They even went as far as blackmailing the government of Denmark. They know that it wouldn't be constructive to give any extra ammo to it's opponents at such a critical time.

    The goal of MS is to subsume OpenSource or extinguish it. Remember the failed MS email standard that contained both a submarine patent and licensing that strictly forbid GPL developement? MS allowed that technology to die stillborn rather than bend and allow GPL use of any of it's patents (as IBM does, see here).

    Once software patent laws are in place and enforcible, do you honestly think that MS would not use Software Patents to toast the one competitor it could never control/buy/extinguish, Open Source and the GPL?

    Heres what they did, from here

    Microsoft had several methods of detecting and sabotaging DR-DOS with Windows. One was to have Smartdrive detect DR-DOS and refused to load it for Windows 3.1. There was also a version check in XMS in the Windows 3.1 setup program which produced the message: "The XMS driver you have installed is not compatible with Windows. You must remove it before setup can successfully install Windows." This was not true, but rather, was an attempt to undermine the competition.

    And heres a taste of the internal emails, from the same source.

    Microsoft's David Cole emailed Phil Barrett on September 30 1991: "It's pretty clear we need to make sure Windows 3.1 only runs on top of MS DOS or an OEM version of it," and "The approach we will take is to detect DR DOS 6 and refuse to load. The error message should be something like 'Invalid device driver interface."

    They threatend Frontpage with an MS bundled product in order to make them sell out.

    They bundled DOS 7 with windows, called it win95 and killed dos competition.

    They bundled Explorer with Windows to kill Netscape.

    They buy up good software in order to discontinue support of competitive OS's. (sybaria, gecad, etc)

    They buy up game companies and tie them to the XBox (halo was originally coming out for the Mac and PC. Not really unethical but damned annoying if you don't have an XBox.)

    Tie sales of computers to sales of windows (Microsoft tax)

    Astro turf campaigns to artificialy generate an image of public sympathy and support.

    Prevented competitors products from being installed by OEMs. (Beos, Netscape, etc)
