The reaction of the lamps is unpredictable, and this allows them to generate really random numbers. [Joshua], a Cloudflare employee, talks about the technical details of the system in a recent ...

Quick! Think of a number between 1 and 10…was it 7? If it was, don't feel too bad, as human brains are notoriously bad at both true randomness and understanding probability. Even if you're too ...

For that you’ll need a true random number generator (RNG), and this open-source hardware RNG uses one of the better methods we’ve seen. The device, called RAVA, is based on a property found in ...

Scientists built the fastest quantum random number generator, creating truly random numbers using light from atoms, boosting ...
