int getRandomNumber() { return 4; // chosen by fair dice roll. // guaranteed to be random. }
Hover Text:
RFC 1149.5 specifies 4 as the standard IEEE-vetted random number.
I prefer using a whole wall of lava lamps for a random number.
Seems like the place to share. Ages ago a group epoxied a webcam and used the random flashes (from cosmic rays?) as their source of randomness.
I think what they're referring to is a company - I think it's CloudFlare - who use a bunch of physical randomness generators to seed their commercial random number generator. One of those seeds is a webcam pointed at a load of lava lamps.
