RANDOM.ORG offers true random numbers to anyone on the Internet. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs. People use RANDOM.ORG for holding drawings, lotteries and sweepstakes, to drive online games, for scientific applications and for art and music. The service has existed since 1998 and was built by Dr Mads Haahr of the School of Computer Science and Statistics at Trinity College

What's this fuss about true randomness?
Perhaps you have wondered how predictable machines like computers can generate randomness. In reality, most random numbers used in computer programs are pseudo-random, which means they are generated in a predictable fashion using a mathematical formula. This is fine for many purposes, but it may not be random in the way you expect if you're used to dice rolls and lottery drawings.
As Voyager 2 prepared to cross over into deep space, the probe began outputting a strange language that scientists could not read. Further analysis suggests some sort of hack, but was it by someone on Earth?

eone Hack Voyager 2?
As Voyager 2 prepared to cross over into deep space, the probe began outputting a strange language that scientists could not read. Further analysis suggests some sort of hack, but was it by someone on Earth?
