    Internet tough guy. Lemme guess, 16 or so?

    The suicidal are often among the more capable in society, apart from their moment(s) of weakness. The only people who are always happy, are the parasitizing-mentally retarded who are generally well-supported by another member or collective of society. Any system of eugenics should start with consideration of IQ (since it is in general the so-far-strongest hereditary attribute correlated with success and flexibility), and be effected through sterilization. Any other suggestion is just aesthetics or mean-spiritedness.

    Let me amend that. The cup doesn't even need to be symmetric, as long as the orientation stays the same across rolls (i.e. you don't spin it). You'll still get a stationary ergodic sequence of rolls.

    First, there are PRNGs which can boost a seed of perfect randomness into arbitrarily much cryptographically guaranteed pseudo-randomness. (It'll be as hard to break the pseudo-randomness, as it is to break the crypto.) I'm no expert on this, but read this if you're interested: http://www.wisdom.weizmann.ac.il/~oded/foc-book.html

    However, a shaken die isn't even a PRNG in any reasonable sense of the word. A die well-shaken in a symmetric cup, by a chaotic system, is real randomness in the sense that the rolls will be a stationary independent sequence. It'd take some work to convince me that I'm wrong on this, but I'll listen.

    Here is a shitty way to use a biased die in such a system for randomness (it just uses the die as a coin, and uses von Neumann's method; if I were smarter I'd do better). Label the faces 1,2,3 as "A". Label the faces 4,5,6 as "B". Roll the die repeatedly and each time "AB" comes up, mark that as "0". Each time "BA" comes up, mark that as "1". (Making sure not to reuse letters. I.e., "ABA" does not count as "01" but "ABBA" does.) Note that the sequence of 0s and 1s you mark down is uniform independent random.

    And yes, I'd much rather have an atomic decay RNG. However, "perfect enough for cryptography" randomness isn't magic. People screwed up in the past, just because they weren't paranoid enough. Le chiffre de Vigenère was good enough for centuries.

    There's no way you can predict the outcome of well-shaken dice. Even if the dice were imperfect, the random numbers could easily be whitened by any number of methods. Atomic decay isn't uniformly random either, of course - the waiting time for decays is exponentially distributed and not stationary (it is decaying after all), but this is easily corrected for.

    Using atomic decay is all about being faster, and less maintenance.

    ZZT was a great intro not only to game design and programming, but also hex editing! You could find the byte which disabled level editing, by comparing your levels to the ones that came with the game.

    Horrible ROMs is where opinion gets interesting. Everyone likes Mario 3 well enough; but only certain people can tolerate Clash at Demonhead. I rate it as one of the best NES games ever, along with Solar Jetman which had huge seamless gamefields and very challenging physics. Too challenging and weird, which is probably why it failed, but there's still nothing like it. It's sort of like a single-player story mode for xpilot.

    I guess my point is mostly that depending on juice for nutrition, for all the sugar you end up getting, maybe not the best idea. Better to eat real whole vegetables and drink cola, than to drink juice and eat processed crap.

    I'm glad you found what works for you.

    My reactions to orange juice and cola respectively, are completely the opposite of yours.

    Minute Maid brand OJ (the most processed) will actually make me vomit; Tropicana just makes me feel sick for half the day; and fresh-squeezed from good oranges is "safe" about half the time, otherwise it's like Tropicana.

    Cola doesn't do this. Still, I usually just drink water, and get my nutrition from actual food, which leans toward the healthy side. No point in drinking a few hundred calories.

    I just read a novel wherein one of the main characters said to himself while arguing a lost cause: "I am the Lorax. I speak for the trees." It was rather poignant in the context.

    If this novel were in the visual medium of animation, it would probably not be possible (or financially reasonable) to make such a reference. That is at least a little bit sad, and part of the "hidden tax" that comes along with so-called intellectual property.

    Just like when he forgot to give air to Laurie when he teleported her to Mars, it emphasizes the fact that he is nearly totally disconnected from most aspects of humanity.

    He blew his enemies up in showers of gore presumably because it happened to be slightly easier than the alternative, even if it spattered a roomful of traumatized bystanders. He knew enough to stop the "bad guy", but beyond that he just didn't care either way. Now that's chilling.

    For that reason I was very glad that they left the gore in, even though in the movie it looks worse than the equivalent scene in the comic.

    Refined sugar is just as new to our bodies, on the evolutionary time scale, as high fructose corn syrup. Even the volumes associated with the modern concept of fruit juice are new: 12 oz. of orange juice is considered reasonable to drink, even though it's equivalent to eating six oranges in a few minutes. Lots more sugar, and much more frequently, than we had during what I'm sure was a pre-technological paradise. Oh yeah, even "natural" juices often have the vitamins stripped out and added back in after pasteurization. Little difference between orange juice and cola, really. If you like one over the other fine, but it's close to a wash nutritionally.

    There's nothing wrong with living your life by various rules of thumb, because it's impossible to get into all of the details in one lifetime. But insisting on the dogmatic conclusions of your heuristics, is sheer insanity.
