  1. Your Money on Next Generation Stun Guns? · · Score: 1, Informative

    Apparently, they got almost 1 million dollers from the USMC for this. And yet they can't afford a real webpage. Does anyone else smell a scam?

  2. movies vs. games on Videogames as Art · · Score: 1

    First of all, not all movies are considered art. Infact, most aren't. Most movies are made to entertain the masses, and so have to appeal to the lowest common denominator. The few movies that are considered "art" are usualy made by smaller studios, and have a much more uncompromizing attitude to their vision. In the same vein, most video games are produced by large studios, and are made to appeal to the largest potential market share. These games should properly termed "entertainment", and considered on the same level as stock action movies. There are some games that, like independent art films, try to rase the bar, and don't flinch from dificult concepts. Ico comes to mind, as does Myst. I think that the comparison of movies and games, vis a vis, art is valid, as long as you remeber that not all movies are art.

  3. National ISP on Spanish Internet Provider's SMTP traffic Blocked · · Score: 2, Interesting

    The article didn't make this too clear, so maybe someone can answer... Is this the only ISP in spain? Is it run by the spanish goverment? Because the way that AHBL phrased it announcement, it seems more like TDE is a smalltime provider in Spain. Can anyone clear this up?

  4. In case it gets slashdoted on Morphing Plane Wings for Efficient Flights · · Score: 1, Informative

    To maximize a plane's efficiency over a broader range of flight speeds, Penn State engineers have developed a concept for morphing airplane wings that change shape like a bird's and are covered with a segmented outer skin like the scales of a fish.

    Dr. George Lesieutre, professor of aerospace engineering who leads the project, says, "Airplanes today are a design compromise. They have a fixed-wing structure that is not ideal for every part of a typical flight. Being able to change the shape of the wings to reduce drag and power, which vary with flight speed, could optimize fuel consumption so that commercial planes could fly more efficiently."

    Morphing wings can also be useful for military defense and homeland security when applied to unmanned surveillance planes that need to fly quickly to a distant point, loiter at slow speed for a period of time and then return, Lesieutre explains. Flying efficiently at high speed requires small, perhaps, swept wings. Flying at slow speed for long periods requires long narrow wings. The morphing wings designed by the Penn State team can change both wing area and cross section shape to accommodate both slow and fast flight requirements.

    Lesieutre and the wing design team will detail their concept in a paper, "Tendon Actuated Compliant Cellular Truss For Morphing Aircraft Structures," on Tuesday, April 20, at the 45th AIAA/ASME/ASCE/AHA/ASC Structures, Structural Dynamics and Materials Conference in Palm Springs, Calif. The authors are Lesieutre; Dr. Mary Frecker, associate professor of mechanical engineering; Deepak Ramrakhyani, doctoral candidate in aerospace engineering; and Smita Bharti, doctoral candidate in mechanical engineering.

    The essential features of the Penn State concept are a small-scale, efficient compliant cellular truss structure, highly distributed tendon actuation and a segmented skin. The cellular truss structure is the skeleton of the wing. The skeleton is formed of repeating diamond-shaped units made from straight metal members connected at the angles with bendable or "compliant" shape memory alloys. Tendons in each unit, like the ropes that shape a tent, can pull the units into new configurations that will spring back, thanks to the shape memory alloys, when the tendon tension is released.

    Since the underlying structure can undergo radical shape change, the overlaying skin of the wing must be able to change with it. Lesieutre says a concept that he thinks holds great promise is a segmented skin composed of overlapping plates, like the scales of a fish. He notes that conveyers on the baggage carousel in airports are composed of a similar pattern of plates.

    So far, the design team has built a tabletop model of the compliant cellular truss structure and a computer graphic model of the wing structure.

  5. It will get better over time (at least a bit) on Increasing the Value of the Domestic IT Worker? · · Score: 1

    A large part of the problem is that, while there is a large, international supply of IT workers, there is only one country that has a demand for them, and that's the US. Once India and China and the rest start generating a larger demand for IT workers, the cost of outsourcing will go up, and make it less attractive to US companies. One thing I want to know is how this effects Europe. We always hear about the drain on the American IT jobs, but how are European IT jobs fairing. Do European countries outsource as much? To where? Is it a problem?

  6. Other Search Engines on How to Build a Search Engine · · Score: 2, Insightful

    I know that other people must use search engines other then google, but who? And why? I could see netscape, because it's the default homepage for many browsers, and maybe Ask Jeeve due to the easy syntax, but why would people go out of their way to Gigablast or Looksmart. Who's even heard of those two?

    Not for nothing, but if this thing realy uses magnets of any power, it's the last thing I'd want in my computer.

  8. Benefits on USB Going Wireless · · Score: 1

    The benefits would be things like wireless printers and scanners. It's also a way to reduce wire clutter (never a bad thing), and, according to the paper, allow connection of up to 127 devices without racks and racks of USB hubs. It would also be nice for digital camaras, since you wouldn't need to worry about the correct adaptor. You could offload your pictures on any WUSB enabled computer. What abount wireless pen drives? Connecting multiple devices to a laptop? I think there's alot of use to this technology.
