  1. It's defining properties are contradictory on Galaxies Floating on a Dark Matter Stream · · Score: 1

    It has to coalesce faster than matter or it won't guide the matter in forming galaxies, but it has to coalesce slower than matter or it won't remain in a sphere around the galaxies that form. It has to form a spherical shape around galaxies for it to be of use in explaining the flat rotational velocities of galaxies, but it has to take the form of long filaments to explain the shape of supercluster.

  2. Re:So how hard is it to program for Cell? on IBM's Radical Cell Processor · · Score: 3, Informative
    Some comments on the first link:

    Writing concurrent software isn't that much more difficult than writing single threaded software, as long as you do a good job of partitioning the system into seperate control loops early on. The main difference will be a period of tweaking and adjusting the interplay of the different threads of execution in the system towards the end of development. It's not uncommon for this last stage to take more time than writing the code initially. A tactic that will help a lot is to build an event log into the software from the beginning that can be used to record when each thread finishes doing some processing task. The later version of the freescale 7400 series processor have many features for just this purpose, I would think the ibm 7400 core used in the cell would have the same features, but I am not sure.

    A good language to look at for how concurrency can be supported is Ada. There is a lot of good stuff in Ada and a lot of bad stuff in Ada, but the designers did a very good job on the concurrency model.

    "He expects to find investors to help pay for the research needed to figure a way to increase the tree power from less than 2 volts to 12 volts sometime this year, creating an alternative to fossil fuels."

    Well, he could increase the potential from 2 volts to 12 volts by putting them in series. I think he probably has a longer way to go than he knows.

    No matter how loud you can crank your stereo, several months of a crying baby in your house will make you appreciate the little bit of the quiet time you get.

  6. Safety, Safety, Safety ... not about improving on Stanley and the Conquest of the DARPA Challenge · · Score: 1
    Great article, but the scary part about it is that the practical application are all about improving safety by limiting human activity - there is nothing here that expands the possibility of performance, it's all about limiting.

    The DOD, major corporations, government, etc. are all concerned with limiting their liablility by limiting what a vehicle can do using AI technology - not about improving the performance of the vehicle. There is an effort to create a truck that can drive itself across the desert at 30 mph, but not an effort to make one that can drive across the desert at 150mph by integrating more seemlessly with the human driver.

    Don't get me wrong. I would love to have a car that could drive me to work each day while I read a book or browsed the net. But the current push in vehicle control systems is more toward limiting the performance the driver can expect than improving it. When I stomp down on the accelerator I need to go fast, right then, not have my acceleration limited by the fuel injection control system - and with he cost of gasoline as high as it, I am not going to stomp on the accelerator unless I have a good reason.

    So much of our intellectual efforts, engineering and legal expertise is directed toward limiting liability and risk aversion that it will eventually cripple us.

    If we lose our will to push the boundaries of what is capable, then we are doomed.

  18. Re:Silly. on Radio Telescope Has Military Uses? · · Score: 1
    It happens again and again.

    Armies start out as guerilla units and invariably strive to become 'regular' Armies, the kind that march around in ranks and files - within a generation they totally forget how to fight guerilla warfare.

    The U.S. Army was outmaneuvered for years by the Comanches in the Southern Plains, even though they had used and faced the same tactics in the Civil War just a few years before.

    During Vietnam, the U.S. never seemed to get the hang of anti-insurgency warfare, but just a decade later they utterly defeated multiple communist insurgencies in Central America with just a few hundred 'advisors'.

    Even the Vietnamese army, that so successfully used guerilla tactics from 1944 to 1975, were forced to withdraw from Cambodia by a sustained insurgency they couldn't defeat 12 years after they invaded.

    The great weakness of all regular armies is that they are always preparing to fight the last war.
