Cryptography, too, relies heavily on random numbers for the generation of unbreakable keys. Better, cheaper ways of generating and handling such numbers are therefore always welcome.

Python 2 and Python 3, the two versions of the programming language in widespread use, include a function called shuffle that can randomize a list or another sequence of data.

A new network paradigm can generate meaningfully random numbers—and fast. In network encryption, randomness has huge value because it’s not “solvable” by hackers. Classical computers can ...
