  1. Re:any signal can be found and killed on North Korea Forced US Reconnaissance Plane To Land · · Score: 1

    If they are smart, the bombs will just destroy a cheap antenna. But even the GPS senders themselves are much cheaper than laser guided bombs.

  2. Re:don't people already do this? on Heise's 'Two Clicks For More Privacy' vs. Facebook · · Score: 1

    Either I accept a site as it is, or I will not visit it regularly. If a site tries to do things that I do not accept, I will not trust it, and I would not visit it regularly. Who knows what they will next come up with?

  3. Re:Use it in orbit on Chinese Want To Capture an Asteroid · · Score: 1

    Well, parts of several asteroids are constiting of a metallic iron/nickel alloy. I don't see why it would be that hard to turn it into some kind of structure for example. It should only need focussed sunlight to heat it up and mold it.

  4. Use it in orbit on Chinese Want To Capture an Asteroid · · Score: 1

    I think the interesting point is to have these resources in orbit. so this can be used the build space ships or a really big station.
    Bringing it down to earth is probably expensive, but using it in space would save the fuel needed to bring that material up.

  5. Just reduce the number of timezones on Ask Slashdot: Could We Deal With the End of Time Zones? · · Score: 1

    For example the USA could reduce the number of time zones to 1 or 2 for the main land. Just look at this map of time zones. China has only one time zone, half of Europe is in the same time zone and Russia just removed 2 of its time zones. Merging a time zone with the 2 neighbouring timezones is just a shift by one hour for the people, but already makes things much easier.

  6. Re:Why.... on Do You Want Best Buy Opening Your New Laptop? · · Score: 1

    I prefer to buy used business class laptops. They can be much cheaper than new consumer class laptops, and still outlast them.
    I don't need computing power on a laptop, so I don't see a reason to go for a new one. If I really need computing power, I have my desktop. But that does not really happen anymore.

  7. Re:Will the file copy/move crash.... on Estimated Transfer Time Is No More In Windows 8 · · Score: 1

    This is the reason why I still don't use the explorer in windows, but a replacement. Try to copy/delete/move several files, if one of them is locked it will cancel the whole process.

  8. Re:I wouldn't hit it on Chinese Researchers Propose Asteroid Deflection Mission · · Score: 1

    It is impacting at 90 km/s, and has a weight of 10kg. That gives it a kinetic energy of 40Gigajoule, which is equivalent to 10 tons of TNT. That is already a considerable power, which might break something up.

  9. Re:its a scam on Yahoo, Facebook Test "Six Degrees of Separation" · · Score: 1

    Little correction... the database will be 400GB, so an iteration would take up to 70-80 minutes.

  10. Re:its a scam on Yahoo, Facebook Test "Six Degrees of Separation" · · Score: 1

    My idea to solve this problem: Starting from a random person, look up all the friends, look up all their friends and so on. For each step count the total number of "friends of friends". If after 6 steps it it would be 50% of all facebook accounts, it would mean that 50% of all people on facebook are within 6 degrees of separation from that person.
    If the list of facebook accounts is converted to a serially numbered list, and the friends lists to lists of account numbers, the whole database would be just 100GB (750 Mio accounts, 130 friends each, 4 bytes per friend). A bit array to check which accounts are in the n'th "friends of friends" list is just 100MB. It should be no problem to run this on a home computer, with the bit array in memory and the facebook database on the hard disk. One "friends of firends" iteration would take just 20 minutes, if we assume that the program just goes through the whole database once.

  11. Re:China is COMMUNIST on China Praises UK Internet Censorship Plan · · Score: 1

    Actually the so-called communist countries called themself "socialists", only in western countries they are called communists. Communism was the next evolutionary step of the society, which was not achieved yet. It was imagined as a society without any unequalities and without a need for money, with abundant resources and people not caring about their own consumption or wealth, but about the society as a whole. There were failed attempts to get closer to this, for example bread given away for free, but that did not work too well (too much bread was thrown away). So it was said that the society is not ready for this yet.
    It is kinda funny how much the Star Trek Federation seems to be real communism.

  12. Re:What is the point? on Cutting Edge Tech Slated For Next Mars Rover · · Score: 1

    Yes, what will the hydrogen react with? How could it be used as a fuel?

  13. Re:US cell system on Leaked AT&T Letter Damages Case For T-Mobile Merger · · Score: 1

    I think the German antitrust agency would never allow that merger since the resulting company would have more than 30% market share. I think the rules are not too different for the European agency.
    A stronger antitrust regulation should also work for the USA.

  14. Re:Why So Long a Flight Time? on NASA's Juno Blasts Off To Investigate Jupiter · · Score: 2

    It is cheaper that way, since a smaller rocket can be used when launching the probe at a slower speed. Also the Voyagers weighted only 722kg, while Juno weighs 3625kg. The higher mass decreases the speed, unless a much larger rocket is used.

  15. Re:Missed the point on The Most Expensive One-Byte Mistake · · Score: 1

    Correcting myself, it's the runtime engine doing this, not the compiler.
    Strings in pascal are just normal variables. For example you can write something like:
    string a,b;
    a = "Hello ";
    b = "world!";
    If (a+b == "Hello world!") ....
    (that is not pascal code, it's just for illustration)

  16. Re:Missed the point on The Most Expensive One-Byte Mistake · · Score: 1

    The big advantage of Pascal strings, which use a counted length, over C strings was: In Pascal you don't need to think about buffer sizes. The compiler can just handle everything since it knows how much memory is needed for the string, and reserves only the memory really needed for it.

  17. Temperature and power problem on Evaluating the Capabilities of Chip-Sized Spacecraft · · Score: 2

    It is probably impossible to thermally isolate and heat such a small spacecraft, since the ratio of surface area to volume is horribly large. So these things will be at a temperature of 3K, unless they are in sunlight.
    I don't think that any battery will work for this, since there are no chemical reactions at these temperatures. They can run on solar cells when in sunlight, but when they are not in sunlight they will be dead and useless.

  18. Re:Far better than the Shuttle, if its reliable on Dragon Capsule Could Be 1st Private Craft To Dock With ISS · · Score: 1

    Would be interesting to know what it would cost to build another JWST. Maybe NASA would have less trouble with getting the funding for the development of it if they could build another one cheaply.

  19. Re:so... on Shuttle Atlantis Docks With International Space Station For the Last Time · · Score: 3, Informative

    There is a nice list on [a href=http://en.wikipedia.org/wiki/International_Space_Station#Docking_schedule]Wikipedia[/a].
    It is not only the Russian Progress and the European ATV, but the Japanese HTV, the SpaceX Dragon spacecraft and something called Cygnus. Payloads are 7t for ATV, 6t for HTV, 6t for Dragon, 2.6t for Progress, 2.7t for Cygnus.

  20. Re:We could do this in the USA on EU Proposal: Shift Farming Subsidies To Science · · Score: 1

    It would also help if your country switched to an election system with proportional representation. As I understand your election system the states with low population density have much more power per citizen than the high density states. And low population density means more farmers.
    Proportional representation would not only change that, but also allow smaller parties to get elected. Oh well, it is easy to suggest that changes from outside I guess. Obviously the parties currently in power would not be interested in that change.

  21. Re:Submarine patent? on Patent Troll Goes After Notebook Cooling · · Score: 1

    Temperature-controlled fans are also pretty old though. I bought such a CPU fan from arctic cooling in 2002. Even my computer from 1993 had a temperature-controlled fan in its power supply. It was just switching on and off, but still temperature-controlled.

    Yes but then I see how the guns are all going upwards when firing in the video. It will make things considerably more expensive to fix that. Everything has to be more stable, heavier and larger.
