..OMG, did anyone see that to register you have to solve a math problem like:

derivative of (5*sin 3x +6cos(-pi/2))

7h15 15 345y. 6 * (05(-p1/2) = z3r0), 50 7h3 4n5w3r 15 ju57 15 * (05(3x).

Nah, he's just the millionth one. The first 999,999 turned up crap. All 1,000,001 could come up with was, "It was the best of times, it was the blurst of times..."

Thanks! Now, to put it to good use:

uint128_t rand() {
/* This number is guaranteed to be random. See http://random.irb.hr/ for details. */
return 0x455fe10422ca29c4933f95052b792ab2;
}

Well, mathematically given an infinite amount of time you could receive the number 42 from a random number generator an infinite number of times.

Given an infinite amount of time, the Windows 95 source code could be spewed out perfectly in sequence from a true random number generator.

Too bad we won't live that long, because we all know how bad-ass the Win95 source code is.

I've read that one, it sucked. The butler did it and they catch him in the end.

Your cat should have typed Hamlet.

Re:Wait...

[E 99]

Actually, a random number generator isn't really random unless it is possible for it to generate the number 42 a thousand times in a row...

However, if you get a 1,001st 42, chances are it's just broken.

Re:Wait...

[Nazlfrag]

Silly statisticians miss the point. Why do all portrayals of the great bard have him bearded? Monkeys were often used as assistants and servants hundreds of years ago, why not use one as a scriptwriter? How else do you explain all the strange spelling and random line breaks? History proves Shakespeare was a monkey without a shadow of a doubt, regardless of silly mathematicians trying to compare the immortal poet, or any other monkey at a typewriter with random numbers. A chimpanzee shares 99.7% of our DNA, yet we call them random number generators? Pseudoscientific quackery at its worst.

I'm a source too, and the first 5 are free:

I got the partial derivative of cos(4x) wrt x evaluated at 0. That's pretty trivial. You could guess at that and do well.

I just checksum my Windows registry.

Web 2.0? monkeys!!

[myowntrueself]

As Kittel and Kroemer put it, "The probability of Hamlet is therefore zero in any operational sense of an event...", and the statement that the monkeys must eventually succeed "gives a misleading conclusion about very, very large numbers."

So in other words there really is *no* hope that web 2.0 will actually produce anything truly outstanding?

Re:wonky definition of pseudo-random

[jdray]

So, what is so hard about generating "truly random" numbers in a computer? I would think that a fairly simple grabbing of arbitrary chunks of memory and using the bytes as floats would produce something that's truly random. So long as your selection method for the bytes was sufficiently arbitrary, there should be no opportunity for pattern development. What am I missing?
