in reply to is rand() random

The only way to create totally random numbers from a computer system is to use special hardware. This hardware could for instance return a number based on some scientifically random natural process such as the thermal motion of atoms and molecules (Brownian Motion). I'm pretty sure that such hardware exists and is used for scientific computing, but I kinda of doubt that your computer has one. :-)
