Huffman coding (minimal redundancy coding) was developed in this manner.
I went to UC Santa Cruz and had the (dubious) privilige of having the late Dr. David Huffman as a professor. He always claimed that when he was at MIT, he was flunking an information theory class, so the professor told him to solve the minimal redundancy coding problem and he would pass... So he solved it...
[for the humor impaired... BEGIN JOKE] Of course, at UCSC, we were always of the opinion that it was actually Huffman's roommate Frank who solved it, and that Frank disappeared that same night under "mysterious circumstances"...:-) [END JOKE]
Like we take Einstien's General relativity as true, yet no one has travelled at the speed of light to see if he was right.
BZZZT! And thank you for playing!
Subatomic particles accelerated to a large fraction of the speed of light do, in fact, behave as Special Relativity predicts. Clocks in free fall do in fact behave differently from those in a stable gravitational field (experiments with clocks in space).
Different subject: Fermat. Fermat's last theorem:
The equation a^n + b^n = c^n has no solutions a,b,c,n in the positive integers for n > 2.
Yes they are easy to solve, but they currently require exponential time.
Polynomial time: The number of operations required to solve the problem is a polynomial function of N, where N is the problem size. (i.e. aN^x+bN^(x-1)+...)
Exponential time. The number of operations required to solve the problem is an exponential function of N, where N is the problem size. (i.e. ae^N).
As the size of the problem grows, the time for an exponential solution grows much more rapidly than a polynomial solution.
For example, the Satisfiability problem: Exponential solution might be the brute force -- try every possible combination of boolean values. Because for problem size N, there are 2^N operations required to check everything, it's exponential.
I also salute you and your countrymen. In ALL of occupied Europe, only Denmark stood up to the Nazis and saved their Jews and other "undesirables". IIRC, King Christaan (sp?), stated that the Jews of Denmark were Danes, and he wore the yellow star himself to prove the point.
Denmark and the Danes deserve a special place in history for all time for those acts.
It seems the majority of slashdot readers (read: redneck ignorant americans) find the idea of other people (read: non-americans) being slaughtered by the Nazis humorous.
Well, well well... Let's all play the Pointless Accusations of Evil Game. In this case, it's a lot easier because the discussion is about Nazism in the first place...
I am Jewish. My wife's family came from Austria (her father was lucky enough to get out as a kid in 1938). I think the French court's ruling is dead wrong.
The problem with Geosync is the latency. Due to speed of light limitations, a point-to-point connection between to locations on earth, going through a geosync satellite is at least 500ms.
If there's no earth-sat-earth, but simply earth-sat connection you still have a 250ms latency.
The other problem of course, is the actual setting up of the web farm. If you are simply relaying through the sat, you still have all the jurisdiction problems. If you have the web farm on board, then you have the costs of building it, rad hardening it (not a minor cost), and acutally finding someone to launch it (I suspect you'd have to use SeaLaunch... I doubt that NASA or ArianeSpace would launch for you). This is a capital investment of several tens of millions of dollars, possibly more.
meter is determined to be 1/40,000 the circumfrance of the planet.
Close, but not quite correct. The meter was originally defined as 1/10,000 the distance from the North Pole to the equator, as measured along the meridian passing through Paris (emphasis mine).
Since that time, several more accurate spheroids have been measured for the earth.
I don't recall exactly, but I believe that the meter is currently defined in terms of x number of wavelengths of a certain frequency of light (which of course is defining it in terms of c.

PacBell is currently installing an external Ethernet DSL router under their 1 year contract special. At least I assume it's an external based on the equipment specification/system requirements that they give.
MS OWNS part of SCO, so they are probably able to get what they want anyways.
Through Open Desktop 3.0, SCO bundled a Unix port of Microsoft C (ODT2 got C5.1, and ODT3 got C6). Microsoft also created a port of (DOS) MS Word 5.0 for SCO Unix. It ran on ASCII terminals and under X.
I would like to preface these comments by stating up front:
I AM NOT A LAWYER
That said...
Actually, I like the suggestion that MS be barred from pre-announcing products. That would get rid of a lot of the FUD. Much of the trade press tends to "review" pre-beta MS software and run the review as a cover story...
Also, it has been bandied about before that if GeorgeW gets elected that he would drop the MS thing. At this point, MS cannot afford to let the matter drop. They have been found guilty of anti-trust violations, and those findings of law can currently be used in civil litigation (and don't believe that that isn't coming!). MS MUST appeal this decision...
The Aspect experiment therefore told us that ANY theory explaining quantum physics HAS to have non-locality (that somehow there is either superluminal (faster than light) signaling or instantaneous action) built right into it
Not necessarily. The world could be local, but it might not be independant of our existence.
Of course, my good buddy William of Ockham tells me that I should agree with you...
Remember, AC, the Danes were the ones who SAVED their Jewish population. Everyone, from King Christian(?) on down, wore the star because they were not just Jews, they were Danes.
For anyone out in the Los Angeles area, Boeing (formerly Rockwell Internation/Rocketdyne) has an F1 on display out in front of the Rocketdyne facility. It's on Canoga Avenue between Victory Blvd. and Vanowen Street.
Take the 101 into the San Fernando Valley and go north on Canoga.
Those F1's sure were big suckers.
I just thought that people might like to see one of these puppies!
Kill Switch comes to mind as a good example, excepting, of course, the horribly bad portrayals of "hacking."
Yes, the portrayals of "hacking" were bad in Kill Switch.... BUT they are perfectly in character with William Gibson's vision of cyberpunk, as expounded from Neuromancer on...
If I understand the NSA's charter, they are legally prohibited from trying to undo Mitnick's stuff. Their charter prohibits them from performing domestic surveilliance. Therefore the Feds cannot LEGALLY ask the NSA to break it. However, I'm surprised the FBI hasn't asked for that kind of CPU power (but a request for that amount of $$$ would probably freak out congress...)

Simple proof.
x = 0.99999999...
10x = 9.99999999...
9x = 10x - x = 9.99999... - 0.9999999... = 9
9x = 9 => x = 1

According to the Jargon File V3.0.0, that comment was originally in the context switching code of Unix V6. So don't go blaming it on Linux.
