  1. Re:Japan has unique opportunity on Japan to Deploy Massive Broadband Satellite · · Score: 1

    To moderate or to post... such a hard choice.

    Japan would be able to build a network of LEO (low earth orbit) satellites that could provide very quick service, if they were willing to build and put several of them into orbit.
    Here's why.

    An object in a polar LEO (as the original poster suggested) passes over the same point on earth at the same point every day. The Japanese would need several satellites to provide continuous coverage to the nation and surrounding islands.

    How many satellites would Japan need? about 80. Iridium, Motorola's Satellite Phone network, had about 80 satellites in polar LEO. These satellites ensured that Japan (and the rest of the earth), had full coverage all of the time.

    Iridium was built for ~$150 million USD. It costs about that much to buy a GEO satellite from Lockheed Martin or Boeing.

    It would be really cool if Japan would build an Iridium-like constellation. It isn't likely due to the ease of purchasing a GEO satellite and the unproven nature of the iridium-style cluster.

  2. Re:Why launch in Alaska? on Satellites on the Cheap · · Score: 2, Insightful

    They were most likely borrowing space on someone else's booster.

    If a commercial communications sat was launching into a polar low earth orbit from a pad in Alaska, and had room, a free ride is the right price for this project. :-).

  3. Re:A Few Random Thoughts on Browsing Alone · · Score: 1

    Presidential voting has been tracked for the last 55 years, since the end of the 2nd World War.

    It has been theororised that Presidential voting was at an artificial high right after the war, because Americans had an unprecedented community engagement in WW2.

    Because of this, voter turnout in Presidential elections declining doesn't mean much.

  4. Re:I'm a government consultant on Dot-Commers vs. Government Contractors · · Score: 1

    I work for a Government Contractor, and I find that work hours and attitude are more flexible here than at my previous employment.

    I choose to work 6am to 4pm, 4 days a week.
    Some of my co-workers come in about 11am Monday through Friday.

  5. Re:Going to acceleration or height? on Magnetic Space Launches · · Score: 1

    But, we don't launch humans to GEO.

    The space station and the shuttle, along with a lot of other things, like the Iridium constellation, are all in Low Earth Orbit, which is only 400 miles up-ish, as opposed to 26K miles up.

  6. Re:UPS Distribution Centers on How Not To Ship Computers · · Score: 1

    I worked for a UPS shipper for a few weeks on campus.

    What you say is true.

    Additionally, if you insure an item for $1000 or more, they will hand-process the items.

  7. Re:And yet.... on Transmeta To Release Next Generation CPU · · Score: 2, Insightful

    Crusoe chips show their worth in these machines, because a couple of power-hungry drives have been removed.

    Dell sold the Latitude LT and the Latitude LS(nearly full-size machines) which had Intel(P/266 and P3/400) chips in them.
    These machines have no internal CD and floppy.

    When you remove some of the energy consumers, those that remain will be more amplified.

    If Intel put PIII/400s or P/266s back into machines without internal removable-media drives, we would see an increase in battery life in those machines as well.

  8. Learning vs. Imitating on Learning Java Through Violence · · Score: 2, Interesting

    In middle school, I built robots for a pascal-based fighting environment such as this one.

    I notice now that I was merely imitating the coding practices found in the example code and the code that my friends and I shared.
    I was learning interfaces and code structure in a very oblique manner.
    I wasn't learning program structure or timing.

    It was a lot of fun, but I didn't walk away from the experience with anything more than a cursory memory of what code is.
