The method used to generate the digits, a pair of 555 timers sending pulses through linear-feedback shift registers, would at best be considered pseudo-random.

So it turns out the random number generator long used by developers working with Google's V8 JavaScript engine doesn't really generate random numbers at all.

Over the years, multiple studies have found that Google Chrome’s V8 JavaScript engine was returning not-so-random numbers when you called the Math.random() function. Today that’s been fixed ...

That means that even if some enemy understands everything about how the random number generator works, they still can’t predict the outcome.

Current methods of generating random numbers can produce predictable results. Researchers said the new method could generate higher-quality random numbers with less computer processing.

Hardware Scientists have created a random number generator that's truly random—and no, that's not an easy thing to do at all News By Jess Kinghorn published April 16, 2025 ...

A new random number generator that uses a micro laser developed by researchers at NTU Singapore is a hundred times faster than computer-based systems.
