  1. Unnecesary Corrollary on The Dismounted Soldier Problem · · Score: 2

    Okay, my suggestion with the sensors was for the creation of a *NEW* task, which is not that difficult. This *NEW* task would not compete with prior tasks (as in walking) at all, and would develop it's own nerve patterns.

    If you are skeptical of what I just said, try this experiment for 1 month: Once a day, for 5 minutes (while wating for the TV commercials to end) *PUSH* up through the center of your palm. Nothing will happen that is visible to you, but the nerve association/muscle feedback will build this activity up as a task in your mind, and you will be able to actualy feel the difference between doing and not doing this task. That difference is detectable, and that is how squid inputs are designed.

    So imagine an input system that allowed you to direct your movement by pointing in an arbitrary direction, with speed/direction rendered analog by a squid glove. (THink about the way you move in your dreams) Or even using a cranial ring (try the above experiment with pushing forward/back/left/right with the top of your head.

    Talk about intuitive, but it does take about 15 minutes before you can get good input from such a system (the first time) but the long term (a day or two) finnese reachable beats hell out all other input devices.

  2. SQUID Sensors on The Dismounted Soldier Problem · · Score: 5

    There has been a lot of development in the squid field over the last few years (squids are a type of minute voltage detector), and while it takes a little training (ususaly about 10/15 minutes of practice to get navigable, which is much less than the time it took most of us to learn the nintindo controler) sqid based controlers have been under development for a few years. The idea is you only have to THINK about moving a muscle, and its voltage changes, but it dosn't actually move until you reach a treshold value. With this tech, there are all kinds of fun ways to solve the walking problem. Personaly, I would put squids in an input glove, and have it respond to *pushes*.

Why don't you encrypt blocks of the size you are pumping out in you packets, while it is not technicaly a stream, neither is the way in which we handle network communications, and it shouldn't really matter (except for real time systems, and people rarely combine real time applications with encryption, because encryption is so slow.)

  6. Duh. on Global Population Implosion? · · Score: 1

    Check out the UN Pop Growth figgures.

    The birth rate for canada, the us, and most of europe has been LESS than the death rate for years. The only source of pop growth in these areas is immigration (or is it emmigration, can never keep those straight).

    For years we have known that as standard of living raises above a certain point, birth rate drops. The world population problem has been one of getting the rest of the world's standard of living up to the point where it's population stabilizes.

    As to why? well, as standard of living rises, people have a decreasing awareness of their own mortality, and increasing diversion to do things that kids would interfere with. People have children to RAISE their standard of living, and in situations where it is already high, the marginal utility of that extra set of hands and the emotional conection between parent and child, can easily become negative, especialy if child labor and chattle customs are discarded.

    A stable high-tech population is MUCH smaller than the one we currently have, which is one thing that many eco-alarmists overlook (I am concerned about the environment, but the world is NOT going to end in five years if I eat a burger)

  8. Metaphors and Subject Translation on On Hollywood and the Portrayal of Computers · · Score: 5

    The problems that we, as hackers (true sense), have with technical movies about hacking are manifold, but boil down to 2: technical inacuracies and overdramatization.

    These problems are not, however, restricted to our little baliwick. And they are not caused by "writers/producers/directors who just don't care", though they are exacerbated by such people.

    The problems are basic ones of the art of storytelling, and I guarantee you, that the further from mainstream experience something is, be it hacking, neuroscience, or astronomy, the more it will be altered in the art of storytelling.

    This is not an evil, because storytelling is about emotion, and emotion is not about technical details. The flashing screens are there because they elicit the emotion in a non-technical audiance that the 5 character error message would elicit in a technical audiance.

    They are called "metaphors", and the form the cornerstone of storytelling, and incidentally, learning. We start with what the people already know, and we add something.

    So when you watch a technical film on a subject which you know something about, ask yourself this: "Was the metaphor of representation good, and did the audiance come away with a better understanding AT ALL of the subject?" If the answer is no, bitch away, but if it is yes, don't critasize the writer/director/producer for poorly explaining a subject in 90 minutes which took you 5 years to understand.

  13. The Current State of Cybernetics on Interview with Kevin Warwick · · Score: 4

    Well, since I am planning to enter this field, I hav some thoughts on the matter. For starters, things we have:

    A) Video: We have direct cortex implants that supply low res/approx 640x480, and we have the beginings of artificial retinas, which could have video piped into them.

    B) Communication: The power requirements/broadcast range of the new ultra-wide spectrum burst tech is perfect for this kind of stuff. Small and Strong.

    C) Output: We have the beginnings of direct brain implanted output, though the main researcher in that field understands lots of nuroscience and little CS, so he isn't makeing real good use of the channels he is setting up. We also have implantable "nerve sensors" for lack of a better word, that have been developed to drive prostetics, that don't go anywhere near the brain, and could be put in a healthy system, just to grab its output.

    D) Audio: Actually, weve had audio for decades, as it's REALLY easy, just tag a voltage source onto the audio nerve.

    We have all the pieces, it seems, but why don't we have cybernetics yet? Well, take a look at What We Don't Have:

    A) Power: We need a good implantable power source, be it a long term battery, a really good thermocouple, or an expansion-generating polymer run alongside a muscle to grab a little juice when you extend.

    B) Community: THe developers working on the parts in different fields are not yet treating them as "parts" and aren't really talking yet. We need more cross-field communication.

    C) Miniturization: While we have all this neat tech, it is simply to big right now to think about an integrated system.

    How We Will Get It:

    A) The Disabled: As much as I may claim I need a Jack, my doctor doesn't believe me. But Parapalegics have a MUCH better case, and between them and the blind, we have a large population that has a genuine need for this kind of equipment.

    B) Insurance Companys: That large population cost certain people a great deal of money, and anything which reduces that cost, is considered a GOOD thing, so insurance companys have and will continue finacning research into this field.

    C) The Law: I don't care who you are, you can't say NO to a blind crippled baby and stay in office, so no one will outlaw this kind of tech, and it will mature.

    D) Crazy Hackers: And then I will go and get some, and just like the comercialization of breast implants, I will keep going to different doctors until I find one who will say "YES".

    On another point, race conditions are mentioned in this discusion, and I think that while a given moderator should be able to specify what level s/he wants a comment to go to, I don't think that moderator should be able to supply more than 1 pt towards that goal.

    So here we stand, at the threshold of creating life, and around us two camps grow. One proclaiming that we are wrong to play God by doing this thing (whom I shall call the Believers); and the other, that God doesn't care about this, or doesn't exist (whom I shall call the Scientists). This drama has played itself out many times before, and shall play itself out many times again; and though I know I cannot stop it, I offer my futile thoughts on the subject in an effort to do the imposible.

    The first claim held by the Believers is that there are regions of action reserved for God, things that, rather than being good or evil, are in some way beyond us, sacrsanct territory for God alone, and to tread within these areas is childish and irresponsible of us.

    The Scientists response to this is to claim that their is no God, and thus no reservation of action can be attributed to him.

    My response is to say "hogwash". If God had reserved an area for himself, it would STAY reserved, he being God and all; leaving us neatly in the realm of natural rights (those things we are physicaly capable of doing or causing to happen) that the Scientists support, without inviolating the God of the Believers.

    The second claim made by the Believers is that there are certain decisions which, were we to choose one of the options available, we would be playing God. Aborition, Geneticaly Engineered Foods, Euthanasia, and the like are such decsions.

    The general response of the Scientists is to say "go away you silly Believer, this is just the first claim rephrased".

    My response is that this second claim, while dependant upon the first, is also "hogwash"; because If I posses the power to act, and choose not to, then THAT is an action, and I am as responsible as If I had acted for the outcome.

    An Example:
    Case 1: I do not know cpr, you have a heart attack, I rage at God for letting you die.
    Case 2: I do know cpr, you have a heart attack, I do nothing, I feel guilty (and am prosecuted) for letting you die.
