  1. Lava lamps are VERY deterministic! by Rick+Schumann · · Score: 3, Interesting · on How Cloudflare Uses Lava Lamps To Encrypt the Internet (zdnet.com)

    Have you ever watched a lava lamp for a while? Especially one that's been around for a while? They're incredibly deterministic.
    I would think this would be a better source: http://random.irb.hr/

    Can two pseudo random numbers actually be combined to give a truly random number?

    LOL, no.

    I'm no mathematician, but I'm pretty sure there's no such thing as 'true random numbers'. I think the closest we can come is the Quantum Random Bit Generator from some years ago.

    3000 rolls isn't anywhere near enough.
    Two: All gamers, apparently, go through a phase where they blame their dice for things not going their way. Get over it.
    Three: This is why there are so many gamers that have boxes full of dice; they haven't got over it yet.
    Four: Still insist on 'physical' dice hamstringing you? Fine. Write a smartphone app that uses the Quantum Random Bit Generator free service. If that isn't random enough for you, then you need psychiatric help, you're way too in denial to be healthy.

    The article suggests using the Quantum Random Bit Generator Service sign-up approach; you do know your maths through at least calculus ... right?

    My solution is to make entire phrases out of captcha'ed characters.

    Like this one (solve differential equations), or perhaps this one (calculate resistor network values)?

    ..OMG, did anyone see that to register you have
    to solve a math problem like:

    derivative of (5*sin 3x +6cos(-pi/2))

    Nice!

  15. Re:Are these the tools for decompiling DNA? by cybrpnk2 · · Score: 3, Interesting · on A New Kind of Science

    I was surprised by this point, too. Wolfram mentions DNA (he MENTIONS just about everything) but not anywhere near as much as I would have thought he coulda/shoulda/woulda. If he'd spent ten years analyzing the various genome databeses out there with the same level of intensity, I think he would have REALLY come up with something spectacular. But that would make him a biologist, and he considers himself first and foremost a physicist...
