    I think we need a world government in place to check the power of multinationals, and to set level playing field in the marketplace.

    Corporations have been very successful at co-opting the power of the American government for their own use. Multinational corporations are greedy and clever. They are doubtless the most powerful forces behind the Hague initiative.

    Don't you think that they would co-opt a world government just as quickly? Don't you suppose that they've been drooling over the prospect of a world government for decades in order to do exactly this?

    Before we all decide to submit to a world government that will protect us all from run-away corporate power, we ought to see at least one instance of this happening on a regional or national level, under living conditions humanity would unanimously find suitable.

    I first heard the SPS idea discussed in a talk given by Jerry Pournelle around 1980 at MIT. My first impression was that it sounded great, and my second was that it was potentially worrisome to be aiming microwave beams at the ground.

    Apparently, though, the risks have been pretty carefully considered and the conclusion is that this isn't much of a problem compared to suntanning or eating a typical American diet. As pointed out elsewhere, this frequency is non-ionizing and therefore does not cause chemical reactions. It can heat you up in significant intensities but nothing more, and the intensities under consideration would cause only about as much heating as being outside on a hot day.

    From the website cited above: What if the beam wanders off from the rectenna? The beam can't wander off target with a significant intensity because it needs constant feedback from the rectenna for focusing. (A phased-array system is necessary for successful focusing onto the rectenna at such distances.) If it wanders off, then it immediately defocusses and disperses to a tiny fraction of its operating intensity. It also can't be used as a weapon for this reason. Even if it were re-engineered to point anywhere with the same focussing, the transmitters would be designed to operate at a relatively benign frequency (e.g., 2.45 GHz) which would not pose a credible threat to anyone. Again, the only thing that will significantly absorb the 2.45 GHz frequency beam is a receiving antenna designed for it.

Thanks to our system of campaign financing, politicians are already paid-for corporate property by the time they arrive in office. The only issues on which the government can freely exercise a will of its own are those issues on which corporations have no preference.

  4. J. Storrs-Hall's space dock on Stepping Closer To The Space Elevator · · Score: 5

    A few years back, John Storrs-Hall (for many years the moderator of sci.nanotech) was talking about an interesting idea that, like the space elevator, is not very far beyond existing material science. It is also probably more economical. The gist is an airport runway, 300 km long and at an altitude of 100 km, with a built-in linear motor that can accelerate a spacecraft. Over 80 seconds at 10 G, the craft accelerates to 8 km/sec, necessary to maintain a circular orbit. Humans (at least young healthy ones) can survive this acceleration. Current approaches to space launch cost around $10,000 per kilogram. The space dock could allow launches for 91 cents per kilogram, dropping to 42 cents per kilogram as the construction was amortized over the first few decades of use.

    From ESR's commentary: expect Mr. Mundie to try to blur the distinctions between open-source development, use of the GPL, wholesale copyright-law violations like Napster, and outright software piracy.

    This strategy occurred to me as a potential M$ move about a year ago. Nightmare scenarios came to mind of legal prohibition of free software development. M$ can certainly buy plenty of judges and lawyers; this may yet not be an impossibility.

    Free software should remain legitimate (not just legal, but a public good) in the public perception. ESR's article is a good start, but appearing as it does in Linux Today, he's preaching to the choir. The involvement of IBM and other big companies with free software lends legitimacy, but is probably too far below the public radar to be perceived as a compelling free-speech issue.

    It would be good if somebody with the connections to do so could get these distinctions clarified in more mainstream media, before M$ has a chance to codify "free software == piracy" as U.S. law.

    • Lloyd's began in Edward Lloyd's Thames-side coffee house in Tower Street in the City of London.
    • Although the exact date of its establishment is unknown, evidence exists that Lloyd's coffee house was well-known in London business circles by 1688.
    • Lloyd himself was not involved in insurance but provided premises, reliable shipping news and a variety of services to enable his clientele of ships' captains, merchants and rich men to carry on their business of insuring ships and their cargoes.
    • The wealthy individuals in the coffee house would each take a share of a risk, signing their names one beneath the other on the policy together, with the amount they agreed to cover. For this reason they were known as 'underwriters'.
    • Lloyd died in 1713 but the coffee house continued to prosper as a centre for marine insurance.
    • By the end of the 18th century the underwriters had elected a committee and moved to their own premises in the Royal Exchange. Only members of Lloyd's were allowed to accept insurance business.
    • The Society of Lloyd's was incorporated by Lloyd's Act 1871 which provided the business with a sound legal basis and laid the foundations for today's market.
    • By the turn of the century the traditional club of marine underwriters had become an international market for insurance risks of almost every type. Lloyd's pre-eminence as a world centre for insurance had been established.
  8. All hope is not lost on A Map to Nowhere? · · Score: 2
    It looks like all those "imagine a Beowulf of X" wishes may not be in vain after all. Chasing down complex causalities will benefit greatly from molecular dynamics simulations.

    This intrigued me:

    Successful biological systems resist simple analysis for the very same reason that they are successful. Every time we gain greater knowledge of any such system we discover that it is far more complicated, redundant, self-healing, adaptable, and resistant to "single points of failure" than it first appeared. If the functioning of the genome were as simple -- and therefore easily manipulated -- as the advocates of the genome project have been implying, it would be impossibly fragile.
    I'm not sure whether to agree with the author that this is a bad thing for would-be gene therapists. For one thing, it offers a bit more of a safety net for highly speculative treatments.

    As far as figuring out causality, this is actually probably helpful. Protein synthesis is reliable despite noise in the system. Accidental conformational tweaks (this coil of RNA happened to be a couple angstroms to the left, instead of to the right, and therefore failed to bind with that site on the ribosome) are somehow rendered insignificant in the final outcome.

    From an analytical standpoint, it would be great if the one-gene-one-protein doctrine worked. But we don't need to fear the analytical worst case, where molecules bump and grind willy-nilly with no discernible pattern, and the reliable production of correct proteins is just some kind of well-balanced accident. There will be a pattern, just not the nice simple one we hoped for. Despite the article's analogy, this will be an easier problem in principle than cryptanalysis. There is still work worth doing here.

    In fact, there will be plenty of work, and much of it will be work to which computer geeks are well suited. Long healthy life available soon would be preferable, but an increase in employment is way better than a poke in the eye with a sharp stick.

    There is one more good consequence of all this. Earlier, it looked like there would certainly be a quick race to lock down the entire genome as intellectual property in the private sector. Now that genome information isn't so immediately profitable, it will migrate to the public domain much more easily. And that will be good for everybody. Unfortunately the complex causal phenomena will become patent targets instead, but with luck that's another battle for another decade.

    The VIVA project was initiated several years ago to bring high-level computer language capability to FPGA programming and to take advantage of the massively parallel capabilities of FPGAs. FPGAs are cheap to make, much cheaper than complex microprocessors such as the Intel Pentium III. The yield rate is higher because the deposition densities are much more uniform for FPGAs than for microprocessors. Furthermore, the entire chip surface can be dedicated to usable transistors, with the potential to provide orders of magnitude more computing capability on the same size chip.

Radio remote controls as used in battlebots are legacy systems, designed to control model cars and kludged to control model airplanes. These applications don't involve combat and really just don't require that much bandwidth.

    I also think that microsecond reflexes are probably overkill; useful reflex time is limited by the inherent acceleration and deceleration times of the robot's parts. Even cats and mongeese get by with millisecond reflexes.

    I'd like to see somebody design a battlebot where they focus on a high-bandwidth control system rather than a bad-ass weapon. (Most of the weapons end up looking pretty lame anyway.) Video cameras are cheap these days, so no reason the operator can't where a headset that gives him a robot's-eye vantagepoint. There are analog joysticks and 6DOF controllers.
