  1. Re:Solar-synched on Ikonos 1-Meter Resolution Earth Images from Space · · Score: 1

    This is not the same as geostationary.

    Ikonos orbit is tuned to precess (to change plane of rotation) synchronously to Earth orbiting the Sun. The plane of orbit does not stay the same due to not ideally spherical shape of the Earth, this orbit is a nice hack to use this 'not a bug, but a feature'.


    This way it is never in shadow and is always passing over the object at the same time: morning and evening. This is a standart orbit for spy satellite (although not the only one possible). Not only the pictures are made under the same favorable light conditions which makes interpretation easier, but you also never loose solar power.

  2. Re:1984? on Ikonos 1-Meter Resolution Earth Images from Space · · Score: 1

    There is a significant difference.

    In 1984, The Goverment can track everyone, but no one can track what The Goverment is doing.

    In Ikonos case, everyone can use its data to check on anyone, including goverment and big corporations.

    If you offer me a choice to live in socity where no one (including big corporations) has any privacy, or society where goverment and big corporations have all the privacy they want, I'll take the first one without thinking for a second. Because if they have privacy, the next second you do not have any and they still have it.

    Therefore Ikonos in a long run is a good thing for privacy.

  3. Authorship of hydrogen bomb on I Am Not Doctor Strangelove · · Score: 2

    Amazingly enough, the patent on radiative compression of thermonuclear bomb was filled by Klaus Fuchs (russian spy) and Von Neumann. The name of Teller is not mentioned in patent application. He however immediately saw the benefits of the idea and pushed for it real hard.

    I'd recommend book by Richard Rhodes Dark Sun: The making of Hydrogen Bomb to everyone interested.

  4. Re:Sigh. on Bright Star Getting Brighter · · Score: 1

    Supernova exploding in few lightyears away will generate enough neutrinos to give you lethal dose of radiation . What is worse, the rock between you and SN makes thing even more dissapointing as some neutrinos will generate secondary particles that are more easily absorbed in you body. Most energy in SN event (99% or more) is in neutrinous.

    Fortunately, Eta Carinae seems to be pretty far from us.

    Do not worry seems like a right attitude unless you have means to move to different galaxy.

  5. Re:Already exists on Software Licenses Get Worse · · Score: 2

    You wish. The software I am using for editing GDSII files (microelectronics masks format) just shuts itself down without bothering to save data or making sure that database stays uncorrupted.

    Anyone has pointers to free UNIX GDSII software (except for MAGIC)?

  6. Futurological Congress on Deep Magic: Matrix, Menace and Virtual Reality · · Score: 1

    Try to read this story by polish writer Stanislaw Lem --- IMHO, one of the best SF writers of this century.

  7. The problem with decryption contests... on Adam Beberg Leaves Distributed.net to develop Cosm · · Score: 1

    The idea is to do it because it can be done. It is a game.

    As a side benefit those guys worked out many issues with distributed computing which may apply to other areas like SETI.

  8. Why Moscow? on Elbrus gets Moscow Government backing · · Score: 1

    Luzhkov (Moscow major) pretty much owns the city,
    so you may concider it a private investment :-)

  9. Well, it does let you read foreign press... on The Myth of the Internet War · · Score: 1

    Some other good sources of information:


    http://www.stratfor.com/crisis/kosovo/Default.ht m

    http://www.egroups.com/list/kosovo-reports/info. html

    US coverage is somewhat biased. I do not believe in wars when on one side there are only knights in shining armor and on the other are only brutal murderers.

  10. 10% code, but more than 10% motivation ? on Feature:Free Linux · · Score: 1

    Because nothing did.
