This shows a fundamental misunderstanding of OTPs. Any message of n bits could be encoded as any other message of n bits. Even your "natural language parser" doesn't help. Take an arbitrary "short" message: "A". It is equally likely that it could decode to "I" or "A" or "Z" or any other 1 character string. It doesn't matter if you know what I'm talking about.
OTPs are provably secure, as long as the key isn't compromised, e.g. by reusing it....

I play ultimate with a team that has been a contender to win US and World championships and am on the Standing Rules Commitee of the Ultimate Players Association. At the elite level, teams have multiple, sophisticated offensive and defensive strategies, numerous set plays, individual tactics, and several learned skills, in addition to raw athleticism and intensity.
In addition, since ultimate is self-officiated at all levels, there are ethical imperatives to uphold your personal and team conduct to a higher level. Knowing the rules well and ability to argue a call convincingly are also useful skills.
Saying ultimate is only about "getting in the open" is equivalent to saying soccer is just kicking the ball. As you said, "every sport involves deep strategy" when played at a high level. Playing at lower levels, not so much, but that's true with all sports as well. The sophistication possible grows with the skills, athleticism, and intelligence of the participants.
E.g. If you're playing ultimate at your family reunion, simply completing a pass is going to be difficult enough in and of itself. When you've got 14 players on the field who can huck the disc consistantly 70+ yards and run a 40 in 5", adopting some strategy is going to make the game much better.
The material, in and of itself, matters less than what the engineers do with it. It simply being made of carbon doesn't necessarily make it stiffer or stronger or lighter or more durable than a steel, aluminum, or titanium equivalent part.
That's not a 13 cm piece of metal, that's a 13 cm piece of carbon fiber composite. It may not have any actual performace advantage, but carbon fiber is much sexier than metal.;-)
Q: Which has more mass: a pound of gold or a pound of feathers?
A: The feathers have more mass. 16 avoirdupois ounces in a pound of feathers. Gold is measured in troy pounds, of which there are 12 troy ounces. (483.6 g feathers vs. 373.2 g gold)
Q: Which has more mass: an ounce of gold or an ounce of feathers?
A: The gold has more mass. 1 avoirdupois ounce is equal to 0.91 troy ounces. (28.3 g feathers vs. 31.1 g gold)
Disk drives cause major headaches with KB/MB vs KiB/MiB. At one point, I remember looking through ads for HDs, and saw MB equal to 1,000,000, 1,024,000, and 1,048,576 bytes.
What about the so-called "mega-proxies" from certain ISPs? They make all of their requests from hundreds or thousands of users look like they're coming from the same IP address.
The TJ-27 and T|E seem to be pretty equivalent: the only difference I see is the T|E's MP3 vs the TJ-27's camera. The TJ-37 (for $300) has either of them beat: MP3, camera, and 802.11b.
While Sony never had a sub-$100 handheld, they always seemed to have better features than their Palm/PalmOne competition at any shared price-point. They also had the highest-end models. The Clies were innovative and interesting. Personally I own a Palm, but that's largely because MemorySticks are stupid and my digital camera uses SD.
Once again, people seem to be forgetting that Sony doesn't cater to the "one percenters" here on slashdot
That's not the point.... The TH-55 in Japan and Europe is virtually identical to the one in the US, with the exception that Bluetooth is disabled. It's not a matter of being a "one percenter," the annoying thing is that they already did the engineering for a fantastic product, released the product in several markets, and then went out of their way to remove a feature for the American version.
The Japanese/European TH-55 is as close to a perfect "tablet" style handheld as I've seen: great screen, good battery life, 802.11b, Bluetooth, and it's compatible with all of the PalmOS apps I already have. I would have been pretty tempted to get a non-US one if the my current Tungsten|T died, but the US one is crippled since I use Bluetooth.
Not quite. Chess isn't a "solved game" like tic-tac-toe. At this point, it hasn't been determined if so-called "perfect" play by both sides would lead to a draw. There exist plenty of games that end up with one or the other player winning.
"If you really need those extra buttons, you may as well buy a new mouse."
Only problem with that is you can't get a second (or third) mouse built-into a notebook. I just wish Apple allowed for pointing device choice in the ibook/powerbooks. Just making them modular so a third-party could provide replacements would be sufficient. I hate trackpads too. I have both a trackpad and an "eraserhead" on my laptop and never use the pad. Didn't the original Mac Portable allow swapping out the trackball for a numeric keypad?
You're wrong. Quantum mechanical effects can be truly random. Nuclear decay is a good example of this.
Set up a piece of radioactive material next to a geiger counter, plug your geiger counter into your PC and you can generate all the random numbers you want.

THe following is a list of Palm devices that have some form of memory expansion:
Every one ever made by Sony
Every current Palm except the cheapest Zire
Previous Palms: m125, m500, m505
Every Handspring non-phone model (visors and treo 90)
every Handera 330 and TRGPro
AlphaSmart Dana
Every Acer model
etc....
(check out the PalmEvolutionary Tree. of the 67 models listed there, about 22 don't have some form of expansion....)

That HowStuffWorks article is wrong. It completely ignores the reconstruction filter in CD/DVD or D/A converter. Any well engineered D/A system will capture ALL of the information up to 1/2 the Nyquist frequency assuming you don't exceed the dynamic range. The reconstruction filter turns the stairstep output into a smooth analog representation and is a necessary step in any good D/A.
Even though PCM is limited to 65536 discrete steps, this amounts to over 90 Db of dynamic range in a properly dithered recording. Although a record does have a continous representation, it is limited to something on the order of 50-60 Db of dynamic range because of background noise and the physical limitations of the vinyl, the cutter, and the playback medium.
In 1993, I bought a machine with 16 MB of RAM, a 420 MB HD, and a 66 MHz processor for $3000. Damn, it played a mean game of Doom back in the day....
Nowadays, I have a 150 MHz processor with the same amount of ram, and 256 MB of removable storage, I got it all for less than $500, and it fits in my pocket with several days of battery life. (larger storage is available, but it's absurdly expensive.)
The only spec my old computer beats my Palm in is screen resolution, but XGA really wouldn't be all that useful on a 4" screen.

Up to the Nyquist frequency (i.e. 1/2 the sampling rate).
