Random Numbers

[a hacker]

While I am not a beginner, I am not really experienced, in a sence.
I am still mystified upon how you can create a fairly random number
generator.  I mean, as long as the program generates different
numbers each time.  Something like this would be sufficient (on a greater
scale):
	$ a.out		$ a.out		$ a.out
	3		1		2
	2		3		1
	1		2		3
	2		1		3
	1		3		2
	3		2		1

As you see, it is really just pseudo random, but there is no such
thing as really random numbers from a computer.

Can anyone help?
