  1. 80,000kg to GTO? No way... on More on the Orbital Space Plane · · Score: 2, Informative

    Better recheck your numbers, this is WAY off! It is more like 10,000kg at present

    Exactly! Government incentives for commercially developed space transportation is definitely the way to go. I mean, what could go wrong?

  3. Nothing you can do on What Are Software Author's Rights For Recognition? · · Score: 1

    You really have no recourse here. Unless you and the company agreed to different terms beforehand, ahything you wrote while employed by them is owned by them. They can do whatever they want with it, including giving credit to the wrong person.

  4. They're missing one point on Beer In Space · · Score: 2

    Carbonated beverages (beer, soda, etc) are not used in space as the body relies on gravity to dispose of the excess CO2. So unless you want your stomach to fill up with carbon dioxide, I would recommend sticking to other forms of alcohol. The vodka that the Russians drink seems like a better choice.

  5. Re:Doesn't even understand own product on Sun Moves Toward "Open Sourcing Java" · · Score: 2

    First of all, Sun has already released the source to the JVM, quite some time ago. It's just not under what some people consider an open license. The article was talking specifically about changing the license to GPL or something similiar.

    Second, it would NOT be awesome if they opened the spec up to everyone, like an RFC. If it was, anyone who wanted to add a new API class or method or change the way a class worked would be free to do so, creating a large number of incompatible version of Java. This is precisely what Sun is trying to avoid. Now maybe they should release control of the spec to a standards body, but that is a different story. Besides, Sun created Java and they should be able to do with it as they see fit. If people don't like it they won't use Java and it will go away.

  6. Only 3 hours on 786Kbps DSL on DivX ;-) Deux Update · · Score: 1

    I guess the one thing stopping this from taking solid root is that on a 56kbps connection it would take, like oh... FOREVER to download or upload any file that side. DSL runs you 1/2 to 1/4 of forever, and a T1 brings it to a day and a half. (T3 makes it 8 hours.)

    Your figures are slightly off. On my 768Kbps DSL it would take about 3 hours to download 650MB from a reliable host.

  7. Re:Must be quite a laser on NASA To Build Laser Space Broom For ISS · · Score: 1

    The goal here is not to destroy the target, simply change its velocity enough that it will fall out of orbit and burn up in the atmosphere. It would use photon momemtum transfer, the same way a solar sail would work. And the laser is not planned to be space-born it will be ground based.

  8. ABM Treaty on NASA To Build Laser Space Broom For ISS · · Score: 1

    It more likely would violate the anti-ballistic missle treaty, as any technology developed would be extremely useful in shooting down intercontinental balistic missiles.

  9. Not what this means on Microsoft Releases C# Language Reference · · Score: 1

    Since this was rated up to 4 (informative) I think I'll have to post this and correct the original posters misunderstanding. My impression from reading the document was not that you didn't have to explictly declare variables, you do. It's just that they are automatically set to 0 or null when the program starts. This fixes something that can cause a lot of problems and potential security violations in C/C++. When a program starts in C/C++, variables are not set to 0 by default, and will contain whatever happened to be in that memory address before the program started. This is what they fixed and seems good to me. Programs with misspellings will not compile, same as C/C++.

  10. One sided article on RMS On eBooks · · Score: 2

    This article is incredibly one-sided. While I would like to be able to read books for free as much as the next person, there is no universal right that I should be allowed to do so. Authors spend a lot of time creating and writing their works, and if they don't want to give them away to everyone, they shouldn't be required to. There are plenty of methods available to give digital information away for free, but not very many reliable ways to control access to digital information. I know a lot of people don't want any, but if you want to see quality works be published in a digital form, it has to happen. I totally disagree with the statement that most people would click to send the author one dollar if given a choice. How many people actually pay for shareware they use? (in the general public, not you personally, so don't get morally offended) Look at public radio and TV. If people would pay out of a sense of responsibility, they would not have to have continuos fund drives, and they would be the most popular outlets for programming available, which they are not. Bottom line is that authors want to make money for their published works and having them freely available will not allow them to. They will be forced to stick to printed works, or stop writing. While I'm not saying that any of the current systems are any good, simply saying there should be no copyright enforcement is very shortsighted and selfish.

  11. Re:IP Space Increase on Vint Cerf On Broadband, Wireless, IPV6 And More · · Score: 2

    Actually to use four numbers in decimal format to represent 64 bits it would have to be four sets of 16 bits. A 16 bit number is from 0 to 65535 so the format would be:

    65535.65535.65535.65535

    a little unwieldy, no? And that's only 64 bits. IPv6 has 128 bits, I believe. So as you can see, sticking with the 4 place addresses and decimal format is really out of the question.

  12. Have you read any of the past discussions? on Mir Reactivation Mission to Launch Monday · · Score: 1

    Iridium takes what, a couple guys with telescopes and slide-rules to make sure the birds stay in the right orbits?

    You obviously have not been reading much of the discussions about this subject. According to posts, supposedly from Iridium engineers, the satellite constellation needs constant monitoring and controlling from several control centers throughout the world, just to maintain the satellites in their proper orbits. Not to mention the countless gateways to the land based telephone system in order for the calls to be placed properly. So basically, Iridium can't make money for anyone, even if you got the satellites for free. Otherwise someone would step up and buy them.
  13. Re:hmm... (NOT) on Get an ACME Klein bottle! · · Score: 1

    I believe that it has to do with the speed at which galaxies are rotating. If the mass of a galaxy were only as much as all of its visible matter, it would fly apart because it is rotating too fast. Hence astronomers have deduced that there must be some "dark matter" adding mass to the galaxy to keep it together. Also I seem to recall something about the mass having to be distributed around the outside edge of the galaxy because of the rotational characteristics, but I can't remember exactly what.

  14. Vostok was never hospitable. on Life on the Moons of Jupiter? · · Score: 1

    Actually I believe that lake Vostok is a lake of melted ice completely encapsulated inside of a glacier. The pressure of being under 4 km of ice causes it to melt at that depth. Therefore it would have never be "swamplike, teeming with life". Any life there would have had to have been deposited on the surface ice and then been covered over with layer after layer of ice for eons. Surviving the whole time.

  15. Strong governments are no fun. on Smile for the US Secret Service · · Score: 2

    > It seems to me that measures like this increase the ability of the government to enforce the law, regardless of what that law actually is.

    > However the problem is not the databases and so on themselves, but the laws they are being used to
    implement.

    I'll try to give my opinion, expressed very badly I'm sure, of why I disagree. I believe you are right in saying that measures like this increase the ability of the government to enforce the law. And let's also assume that you can have a good or a bad government. So the four choices would be
    1. A weak good government.
    2. A strong good government.
    3. A weak bad government.
    4. A strong bad government.

    It seems to me that the only totally unacceptable choice would be four. If you have a strong bad government you're pretty much screwed. At this point you can't really change anything and you're stuck. Once a government becomes strong, it is very difficult to make it weak again, governments do not like to give up power. So a lot of the effort in the US is directed toward keeping our government from getting too strong. This way if, at some point in the future, the people decide that the government has become unacceptable we can still do something about it.
