  1. Re:25K?! Argh... on NASA and Google To Back New "Singularity University" · · Score: 1

    Yeah, but then we have the quite reasonable fallback: extraordinary claims require extraordinary evidence.

    A completely physically-naive person would look at hard drive capacities from 1960-1990 and extrapolate a trend to infinite capacity. Physicists and the hyper-specialized niche of hard-drive boffins know better.

    Now, which one does Kurzweil sound more like?

    The thing about stat 101 is that anyone can be wrong based on it! Statistics should be called "numerical skepticism".

    Singularitarians, being primarily hopeful, lose out on the selling point of the nearly-defunct Christianity: there's no skin off my back if I'm wrong. Since I'm a technical person, I'm contributing to the singularity if it's going to happen; and merely making a living if it's not. There's no hell for me to go to, so I don't see the need to believe in a Miracle.

    (In case the last paragraph is misleading, I do what I do for the love of it, not for the money.)

    The hell it isn't.

    When I come up with an idea for an inequality, or even just a probabilistic model, I can whack together a few lines of R and see how it works. Usually almost instantly! Basic programming (i.e. work) literally replaces "genius", and I don't need to think like Hardy and Littlewood, or Fisher, or Feynman to get really good hints as to why some ideas of mine are good, or bad. They say Feynman solved PDEs in his head by visualizing the solutions. For the rest of us, there's a computer. That's a "force multiplier" of possibly inconceivable magnitude.

    Of course, most people don't do this with a computer. That's probably a pity. But the point is, the computer (along with basic programming skills) turns motivation, curiosity, and insight into results without the need for the mystical catalyst of "genius".

    On the other hand, these results are infinitely more modest than The Singularity and, honestly, will likely stay that way. Really, since we can't even agree as a species whether we cause global warming, I'm not holding out hope that we're looking at technological utopia in a few decades.

    If I were to believe in its feasibility, I'd rather take my fantasy tempered by reality... I'd go with Hugo de Garis, who predicts a gigadeath war between AI and its supporters, against the reactionaries. There would be a hell of a lot of people who, once computers start replacing us, will have a rather dark (but not totally unjustified) idea about what would come next...

    I think the idea is that people with $25K go to Singularity University in order to "learn" how to spend their money on more singularitarian bullshit.

    Any place of learning, from high school through community college and up to grad school, is Singularity University. Hint: take math and science classes. I think I'd rather take linear algebra and diff eq. at a community college than pay $25K to hear a blowhard's dream for the future. Hell, if you take a decent statistics class you can outsmart these guys by learning about what's wrong with extrapolating a fitted curve past its support is not valid...

    What I have noticed is that these days, any mention made of an income disparity at all receives a knee-jerk accusation of communism. Even when the mentioner explicitly disdains the idea of any social programs or income adjustment, and is quite willing to accept his struggle.

    This is extremely disturbing to me... The end of civilization comes when the elites are too weak and ashamed to even accept the fact that there is an under-class.

    Did you know that the Brothers Karamazov was originally written as a series for a newspaper over the course of months? I wondered for a while, why the chapters seemed to start with a recap of the previous one.

    Anyway, agreed, it's great. I've noticed though, that in contrast my favorite science fiction tends to be very weak on characterization (e.g. Vinge) and more focused on entire societies and their conflicts and trajectories. A "systems view" if you will.

  9. Re:Turbo button... on How To Diagnose a Suddenly Slow Windows Computer? · · Score: 1

    C128: You have to be in 80-column mode (which was really impressive to me back then...) to use fast; the (separate) chip for 40-column couldn't operate at 2MhZ, and thus would disable. (The "slow" mode was 1MhZ btw.)

    Turbo: I think that the turbo button was there for compatibility with old software. Software wasn't always written with explicit timing routines, so usually a game written for an 8MhZ machine would be unplayable at 25MhZ. There were some hacks to slow down software by introducing interrupts, but this of course wasn't as reliable as getting the hardware speed closer.

    As software started to be written with evolving hardware in mind, the turbo button became superfluous. (Today's turbo button is "installing a graphics card" ;-)

  10. Re:Dying Technology on Building a Better CAPTCHA · · Score: 1

    Your description is vague (perhaps intentionally so), but I'm skeptical nonetheless.

    The persistence-of-vision hurdle is easily jumped, by tuning a decay function to interpolate across the animated gif so that it looks like the appropriate single frame. Note, this only has to be done once.

    This leaves the optical illusions. Again, there are really only so many of these, and they can be pattern-recognized and classified as whatever they represent. You can stick them together in any combination but this just adds a segmenting problem. Both of these problems have already been solved for standard captchas (where there is the extra problem of those lines connecting letters, in order to make the segmentation harder).

  11. old-hat hard science fiction on The Science and Physics of Back To the Future · · Score: 2, Interesting

    These kinds of considerations aren't anything new, and injecting them into soft sci-fi like Back to the Future is a waste of time. BttF is enjoyable, though, and does make a great accidental (?) satire of the American dream and hubris. For science, read some Larry Niven or Stanislaw Lem instead.

    For example, Vernor Vinge did something like this, involving teleportation. A teleporter could control both the outcome position and velocity, but velocity was "harder" and took effort proportional to the difference in velocity.

    Therefore, long distance teleports were only feasible along a longitude, and to the opposite latitude, since you had to match momentum or die by either being crushed or flung off into space. The earth's spin matches at lat X long Y, and lat -X long Y, but nowhere else.

    As a result, one of the world's superpowers controlled both semi-polar regions, alternating by season; while the other stuck to the equator.

Basically what happens is that promiscuous women implicitly quarantine the men who find them. It just so happens, if I understand correctly, that there is a portion of the phase-space, where increasing the rate of promiscuity in women serves to reduce the overall rate of disease by concentrating the disease among the promiscuous while keeping men from sleeping with the unpromiscuous women.

    So I told him how much the strippers at that establishment make (most of it under the table) for what is basically a part-time job, and he got real quiet. Then I asked him, since I knew he was under the same "patent transfer" arrangement I was, what exactly the difference was between selling your body and selling your mind, apart from the fact that you'll never get your ideas back, ever. He didn't talk to me much after that. Some people can't handle the truth I guess.
