Well... no. Checkers on a full-sized board has not yet been "solved" in a mathematical sense. Schaeffer's program "Chinook" won the world chanpionship against human competitors, but it has not been proven to play a perfect game.
All in all the Apple laptops are very well supported for linux--builtin Airport, power management, sleep and wake, video and sound chipsets, and USB/Firewire. The only thing I don't have working on my old iBook is the NTSC video output which I don't really have a use for. The build quality is superior to most Dells and the battery life is typically much better. Most of the people working with Linux on PowerPC are running Apple laptops, so the hardware tends to be very well supported by the community.

Well, such a scheme might produce somewhat better compression (especially since the impulse responses of visual neurons resemble 3d wavelets, naturally suggesting a 3d scheme for efficient representation.) I once implemented a scheme using 3d wavelets for optic flow detection, with some pretty good results on canned data.
The drawback is that it requires more complicated encoders and decoders, which use more memory and more memory bandwidth due to the need to decode several frames at once. Today's hardware isn't quite up to the task, especially for encoding in realtime or decoding on a set-top box.
IMO, 3d transforms might help boost efficiency but they probably won't lead to a more mathematically "elegant" codec. After all, the task is to produce an image that fools the human visual system into percieving the image as real thing, using the smallest number of bits in the encoding. Since the problem definition is based on something as big and complicated and poorly understood as the human visual system, the problem solution is going to reflect that complexity. The more advanced video codecs get, the more they will reflect the complexities of the visual system. Look at mp3--it's basically a pretty simple quantized DCT scheme for audio, but getting good performance out of it requires the encoder to know about and exploit all sorts of psychoacoustic masking effects, basically embedding a model of the auditory system into the encoder.

Those interested in playing with Avida and seeing how evolution can be modeled using computation, thermodynamics, and information theory should get a copy of Cristoph Adami's book, Introduction to Artificial Life
I had the fortune to take Dr. Adami's class on the subject. It was an eye-opener to say the least. I think I remember more about statistical physics from his brief overview than I do from any other classes I took on the subject.
RMS distortion and spectra are not meaningful ways to measure physchoacoustical codecs. Codecs typically take advantage of temporal and frequency masking effects which mean that the in many cases large components of the sound can be discarded because they are masked by other sounds in the recording.
If you really want to know if you can hear the difference after re-ripping, or if the iTunes AACs are really CD quality, the best way is to do a blind ABX test (you can find software to do this here.

The account you linked is probably fictional (where's the name of the town? Pictures of the wreckage?

Anyone ever notice that when you buy a rebate-priced item at Fry's, the rebate form they hand you is ALWAYS for a similar item that is NOT the one you bought?
If your application written in C runs, say, 20% faster than Java on the same machine, then when next year's hardware comes out it will *still* be 20% faster. You will save 20% when purchasing hardware to run the application, and that 20% gets applied to all your hardware purchases in the future. Not to mention the marketing advantage of efficiency if there are competing products.
Contrary to your CS conventional wisdom, the difference adds up in many cases when you are talking dollars and cents. It doesn't just apply to the "bleeding edge."
Because it provides little to no practical benefit in the case where every device needs its own charger. Anyway, I have seen phones which use inductive charging. Not a lot of them, because in existing implementations there are few benefits beyonds sealing the case, but they're out there
Right... though again, the DCT and the FT are essentially the same operation -- the DCT is just the real part of the FT (the FT is complex).
No -- the DCT spaces its components at half-wavenumbers while the FT has components spaced at integer wavenumbers. So only every other DCT components would be equal to the real part of an FT component. (that isn't strictly true, either, since most DCTs have a half-sample offset compared to FT)
Interestingly enough it wasn't until the '90s that a "fast" or O(n log n) algorithm for calculating the DCT was found--this is well after it had become widely used in compression.
Also, there is a very long period (about 16 minutes) during re-entry when radio communitation between the suttle and ground is impossible due to the ionization of the air around the shuttle at high speeds. Columbia broke up during the radio silence, so whatever information ground telemetry recieved wouldn't have been too useful.
Well, you have to consider that applying a proven technology in an obvious way to a very slightly different device isn't really worthy of a patent. Title 103 says a patent is invalid if the claimed innovations are "obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains." I don't think it's unreasonalbe to expect that an electrical engineer, knowing of the existence of inductive charging, would consider it obvious to apply it to a "mobile device" if it improved the product in some say.
And toothbrushes come up in this discussion because they are the most common consumer devices to have inductive charging. It is a good technology to use if you are trying to make a waterproof device, which is a basic requirement for toothbrushes.
So, you are saying that a patent would be invalid if there is prior art on using "magnetic induction in connection with another gadget embedded in portable electronics to recharge..." Gee, sounds a lot like my electric toothbrush.
The patentable innovation isn't charging via magnetic induction. That's old hat. The innovative bits are integrating it into a surface so that each device doesn't need to sit in its own cradle to recharge, and despite this having the resulting electromagnetic field be small enough to not cause unwanted interference.
So how is it better? You still have to beatmatch manually. FinalScratch is decent for DJs who don't want to admit that turntable-based mixing is becoming rapidly irrelevant. gdam whomps its ass for live performance capability. Instead of spending 75% of your time making sure that beats and bars line up, you take care of it with a couple of mouse clicks, fire-and-forget.
Bochs is very crude compared to Virtual PC--it lacks a JIT so it has dismal performance, it doesn't implement clipboard sharing or drag-and-drop between emulated instances of Windows and the outside OS, and it doesn't have accelerated 3D video drivers, just to name a few things off the top of my head. Improving bochs to the point where it could be a replacement for Virtual PC would be a big project for Apple.
Finally, since most copies of Virtual PC are bundled with a Windows licence, and are sold to people who would not otherwise be buying a Windows license, I don't see how it would be terribly advantageous for Microsoft to kill it.
