This isn't exactly true. As the author of global illumination renderer I witnessed many situations where FP code in Java just sucks. This is especially the case for trigonometrical operations, where implementations in JDKs >= 1.4 return bit-for-bit identical results on all platforms. This is achieved with math library, thus wasting the potential of direct computation with FPU. This is also the reason why some half-baked benchmarks concluded that with JDK 1.4 Java become much slower, while in fact it is definitely faster save for these FP operations.
BTW, this is a good time to plug my Java app benchmark based on the renderer I wrote: JatMark.
Not necessarily. Photon mapping would probably introduce subtle differences because of biased/noisy kernel estimates and insufficient number of photons. Even with final gathering (which would make it much slower, also due to two large mirrors in the image), the accuracy (which is all this guy seems to be after) would suffer.
Not to mention the fact that integrating direct lighting from spherical sources and calculating depth of field with distributed ray tracing aren't fast either.
Technically, you have three types of color sensitive cells in your retina (so-called S, M and L cones) and you need at least three variables to describe color as seen by humans. That said, nonlinearities in cones' reception make it beneficial for color reproduction to add more variables. Hence RGBE.
Also remember about CMY and CMYK problem in printing, where theoretically CMY would be enough to reproduce full gamut, yet CMYK is used due to ink impurities, which make it difficult to match exact black.
Some years ago I wrote a small aphorism in Elvish for my Tolkien-positive love interest, using TengwarScript (Windows). I'd put in the box with a CD I bought for her, but never got any reaction. Many months (or was it years?) later I've learned that she never saw the card, as she somehow managed to overlook it...
All you need to get Java plugin running is to make a symlink. Once. Since the symlink is in ~/.mozilla/plugins/, you won't have to make any "fresh" ones after you update Mozilla.
Well, these benchmarks are supposedly suggesting that Opterons excell at server-type operations, while workstation performance is lacking. However, if you check their benchmark setups, there seems to be another way of looking at this: isn't is so that Opterons simply run better on Linux rather than Windows?
Certainly unrealistic movement played its role, but rendering is also very important. Just look how much better Dr. Sid's face looks than Aki's. Hers has large areas of smooth skin and unnatural light reflection is very well visibile. Hence, plastic look.
Your are obviosly wrong if you think that MiniMax alone, even coupled with processing power of DeepBlue could achieve anything. Read here about other factors involved.
What is also worth remembering is the fact that Mr. Simonyi founded the chair of "Professor of Public Understanding of Science" at Oxford, which is currently held by Richard Dawkins. His book "Unweaving the Rainbow" is a direct result of all this.
Speaking of Tori's new CD: I am looking for mp3/ogg version. Obviously, I intend to buy the album when it's finally released, but I'd love to hear it earlier. Anyone with URL?
"But an asteroid this size will only affect the size of a large city. There is plenty of time to evacuate the area, assuming you have a day's notice or more."
I don't think you'd like to organize evacuation of a city (not even "large city") in a day. Really.

Physics you say? Just look at your eye (pun intended).
While we are at it, you may wish to check Java application benchmark I wrote some time ago. JatMark
I looked at it with ie 6.0 and many transparent PNGs were broken.

Oh great. Somebody learns that most people are idiots and this is supposed to be news? Just great.

I am posting this from Mozilla installed in /usr/local/mozilla. The link in my ~/.mozilla/plugins is seemingly enough, as Java works. Try it yourself.

Some nice non-game applets I found recently: here and here.
Sir, it does really sound weird for Mozilla user to complain about Java's bloat.
Hotspot optimizes bound checks away. What would be more useful for scientists are:
a) true arrays,
b) FPU-using trigonometrical ops

No, in case of signal loss JDAMs use intertial navigation to aim at the last point acquired by targetting system.

We need "moderation: disgusting", and we need it now.
Well, it lacked subsurface scattering, which is pretty important thing when rendering stuff like human skin. Check it here.

Additionally, if you look for main author's name with google, all you get are 7 links to some other people. Smelly.

Aerostats, here we come!
No, there is Knuth's LCG implementated in java.util.Random. Check the sources.
