...CDs and DVDs have several layers of encoding for error correction purposes. The lowest level is 14 to 8 encoding.
This is not error correction, it is a self-synchronizing encoding akin to barcode to make sure that long runs of zeros and ones do not become long spaces or long pits on the surface, as this could cause synchronization loss.
The 14-bit codes express the 8-bit bytes in terms of interleaved pits and spaces, where each pit or space can be either "short", or "long". At the lowest level a CD/DVD drive is effectively a barcode reader that tries to account for instability of the CD/DVD rotation speed; therefore no pattern is "invalid", and they do not interact with the RS error correction codes.
IIRC, they have a counsel of sorts to deal with things like this, where something comes along that is so much better and safer, but no more complicated, comes along.
"Comes along", you say? Don't you find their willingness to benefit, as a society, from technological advances without contributing back, as a society, anything even remotely technological, somewhat parasitic?
You are dead wrong at least about the credit card companies. When you call an 800 number, it uses ANI identification that cannot be spoofed unless you run your own phone company, not Caller ID. When you call from a cell phone, the cell phone carrier has to identify you by your phone of SIM card before they decide what caller ID to send out in the first place.
Unlike IOC, we have no idea if there were any Russian (or Korean, or Brasilian, for that matter) participants this year. The identities of the authors are kept away until we agree on the set of winners.
It'd also be interesting to know how far from the athletes the gun is located and if sound travel speed can have an impact on things (how is the electronic system synchronized to the gun? via sound? some other way?)
There is a loudspeaker right behind each athlete. Watch some Olympics on TV, duh!
I'd like to point people's attention to Fabrice Bellard's free portable retargetable emulator QEMU. The technique employed in QEMU allows to enjoy most benefits of JIT (except dynamic register allocation and cross-basic block optimization) without actually writing any code generator for the host processor.
Implementing PDP-11 and VAX in QEMU will achieve unprecedented (in a free emulator) speeds.
It was never possible to live free and untracked in a big city.
What had changed is the technology that allowed to track you with better efficiency and with lesser expense (no need to pay an agent or a private detective to sit in a car across the street), that is all.
Am I the only person here who was never addicted to caffeine and does not know how does caffeine withdrawal feel like?

In some languages some constructs bear the mark of the speaker's gender; e.g. in Russian there is no way to say anything in the past or present perfect tense without revealing your gender: "I (male) have said" is "Ya skazal", but "I (female) have said" is "Ya skazala". To assign a gender to a talking robot is therefore a necessity.
As described in their FAQ, they need a cycle that contains a Distinguished Point. But it is not guaranteed - there might as well be a simple fixed point or a small cycle that does not contain any DPs. They do not address this in the FAQ at all! The clients may be stuck in loops without sending anything to the server (having effectively found a collision), but the organizers will have no idea.
As for thinking for yourself, is it better to just blindly follow the world's pattern of greed, selfishness, anger, and lust or to seek obedience to God's command in that we love the Lord our God with all of heart, soul, mind, and strength and love our neighbors as ourselves?
Where does this black-and-white world view come from? I, for one, am perfectly capable of forming my own pattern of greed, selfishness and anger, and lust, and pride of it (NB: all in moderation). I don't need to follow anyone else's pattern, thank you. And as far as your obedience, love, heart, soul, mind, strength and other nice qualities stop one inch short of my personal space, I'll love^H^H^H^Hrespect you too as myself.
Freedom demands eternal vigilance, and you just gotta do it for yourself. That doesn't mean you can demand others apply that vigilance to their own lives; their concept of Freedom might just be different than yours.
There are valid reasons why I shouldn't run a spambot. But are there any valid reasons why I shouldn't be allowed to run a spambot?
There are none. Make yourself an intranet and run spambots there to your heart's content. Your freedom to run spambots ends at my incoming port 25.
When I ordered Dish Network with the (then new) DishPlayer, I kept my basic cable "just in case".
As it turned out, it was a good decision: Dish did not carry the SF Bay area NBC affiliate for about a year in 2001-2002, so the cable came in handy; the price of (bundled broadband + basic cable) is within a few cents of unbundled broadband - it will be more hassle than worth dropping it; and now this.
When the NBC crap hit the fan I listened to Charlie's excu^H^Hplanations, and I just knew it was bound to repeat.
I had this argument only this morning with a colleague. He shouts across the office to another colleague and has ongoing conversations with the other chap at the top of his voice.
When I asked him if he could have that conversation over IM he told me to stick my fingers in my ears or to listen to music.
First, buy a little voice recorder and record what he says.
Then, buy the most expensive noise-blocking earphones yuo can find and bill him! If he refuses, threaten him with small claims court.
Here is another real story: a PDF document about a town in Iran with a comparable level of the natural background radiation, and people live there quite happily (or as happily as one can live in Iran, for that matter).
I'd like to get rid of that ugly dish with an ugly contraption to receive signal from two satellites; where can I get the same flat thing to put on my roof, but without GPS and the gyros?
With all the achievements in x86 binary code analysis, instrumentation and compilation (think of valgrind or Transmeta, to name just a few), wouldn't it be possible to read the kernel binary into some kind of a compiler, find all uses of the instructions that have to be replaced, replace them (and the adjoining code, if necessary) with the Xen interface calls, then reassemble and relink the kernel?
How extensive and how non-trivial are the necessary changes?

Not much closer, but closer.

One look is enough to see that A, E, and I have to be typed with the left pinky. These three buttons pave a wide road to tendonitis of that finger.
The study also shows that avid gamers are also as drug-addicted, violent, sexually perverse, and prone to suicide as everyone else.
