  1. misdirection indeed on Google's Search Copying Accusation Called 'Silly' · · Score: 1

    Summary:
    google > We made up results, and you had the very same results. You wouldn't have the same results unless you copied.
    microsoft > We are not copying because that wouldn't make sense. Google feels blahblah, Google is blahblah

    It needs an immense expertise.

  3. Re:Supermassive Black Holes? on What Exactly Is a Galaxy? · · Score: 2

    I thought galaxies were determined by the presence of a supermassive black hole as its primary gravitational organizer ... but the paper doesn't even contain the word 'black'. Globular clusters sometimes have medium-mass black holes, but no supermassive ones.

    Is my knowledge rusty?

    Not even rusty, this has never been the case. Only in the last decade it became known that black holes are in the center of most galaxies. Also, the black hole is pretty irrelevant* to the galaxy as a whole, except for the few surrounding stars, it is not the "primary gravitational organizer", it just happens that in the center, so much mass accumulates that photons can't escape. That's all.

    *milky way galaxy number of stars = 3e11, black hole mass = 3.7 million stellar masses

  4. Re:America has jumped the shark on Teachers Back Away From Evolution In Class · · Score: 1

    How about illustrating evolution and selection in Biology classes by an experiment?
    You'd need a quickly breeding organism, and in each generation you take out the ones with undesired elements. Could be insects, plants, worms. Run 3 experiments in parallel and try to make 5 generations.
    Evolution is the bread and butter of horse owners, flower growers, dog breeders; it is visible to them, you need to make it visible to students.

  5. Re:These systems which preach safety and security. on Ford Building Cars That Talk To Other Cars · · Score: 2

    In the sense of network architecture, the only way I would be even semi-okay with this would be if it really was completely decentralized and peer-to-peer.

    The associated research area -- pretty old by now -- is called VANETs.

  6. Re:Whatever gets the space program more funding... on Does the Moon Have Military Value? · · Score: 1

    The moon is of endless strategic military value!

    Why? What can you do from the moon that you can't do from earth or orbit? Oh yes, destroy continents. But what's that worth? Also, there is quite a travel time after starting an attack. So the strategic value of a militarized moon is that you can threaten to kill everyone. Great. We already have enough nuclear bombs to do that.

    No thank you. Keep weapons out of space. If you don't, you set a precedent for China, Russia, India, Iran, Brazil, ... Lets stick to the treaty.

  7. What are you trying to achieve? on Is Retaliation the Answer To Cyber Attacks? · · Score: 4, Insightful

    Is the attack scenario one bad guy?
    Then you should contact law enforcement. Also you should make sure your security set up is appropriate.

    Is the attack scenario that you are an big company and people attack you because you are known?
    Then you should make sure your security set up is appropriate. Attacking people is pointless because new ones will turn up all the time.

  12. Re:How Absurd on Does Typing Speed Really Matter For Programmers? · · Score: 2

    Another argument: Pair programming increases code quality. Surely two people sharing one keyboard doesn't increase the typing speed.

  13. Re:Depends on what language you use on Does Typing Speed Really Matter For Programmers? · · Score: 1

    I don't think GP was talking about autocompletion only. Refactoring (moving or extracting) class/method, generating classes/constructors/getters/setters/...
    Those I have not seen in any other language to this extent. Java is so great in this regard because it is statically typed and doesn't have too much language expression options (which also makes it verbose). And I'm not even mentioning the code analysis and testing tools.

  14. Re:Fast remote X connection... on NX Compression Technology To Go Closed Source · · Score: 1

    Use sshfs to mount your remote machine's disk and then run meld locally. No remote access protocol will be faster than that.

    You are ignoring the fact that all the data has to be transferred to localhost then, which will be more costly than running a GUI remotely.

  19. Re:Yo, Jimmy, I've got an idea: on Should Wikipedia Just Accept Ads Already? · · Score: 5, Interesting

    Wikipedia is not collecting money for Wikipedia. Wikipedia has enough money.
    Wikimedia is collecting money to build up Wikipedia's sister projects and get funding for 3rd world education projects (e.g. free books). But since Wikipedia is the most prominent project, they go from this angle.

    Maybe Wikipedia having ads would be the 'internet way'. But the 'internet way' is also shitty websites. And all the projects with 'paid writers' or 'experts' have failed compared to Wikipedia. So better be independent, and (roughly) continue the way its done now.

    Of course, I agree with your criticism. I would even be ok with a regular (e.g. every 3 years) database reset that deletes the discussion pages and user (privileges).

  20. Re:These documents should not be released. on WikiLeaks Under Denial of Service Attack · · Score: 1

    Exposing what was talked about freely in private, can jeopardize international relations, and be easily misunderstood out of context. And keeping friendly international relations and a mutual understanding, across cultural and religious borders, is of utmost importance in todays world.

  21. Re:Alternatives? on The Coming War Over the Future of Java · · Score: 1

    [Objective-]C[++], Pascal, Fortran, or whatever is just as portable as Java, if not more so.

    Show me a GUI "Hello, world!" that'll run on every platform Java does - even if Java windows look like shit. Java isn't just a cross-platform language, it's also a cross-platform toolkit that hides all the OS specifics, far more than any of the languages you mention.

    wxWidgets - helping X-windows newbs like me since at least 1997.

    People answering Qt, wxWidgets, .NET etc do not understand this point.

    Java is designed to be platform independent. It is not only implemented to be platform independent. They actually have/had people crafting APIs. Look for instance at the Bluetooth API. It is straightforward, can be explained and so on. It is not implemented in Java itself, but the API has been crafted so that others can implement it beautifully. And it works! There are implementations by various providers for their hardware. You never have to deal with the specific hardware.
    Look at .NET on the other hand: You have a number of libraries trying to bring Bluetooth onto .NET. Some are nice. But nowhere is guaranteed that
        - you can work with the same API with different Bluetooth hardware
        - you can work with the same API with different OS hardware (e.g. mobile device vs. desktop)
    With Java you can develop and unit-test your mobile app on your desktop. With .NET you need an emulator.

    This is the difference between a library that provides abstraction for one aspect, and implements it for a range of systems (like wxWidgets provides a GUI delegating to OS-specifics), and a true platform, or virtual machine in the true sense of the word, that hides all aspects from you.
    It does not matter if you don't like Java's syntax. Build on the JVM. There is nothing like the JVM, nothing that has the same attitude.

    PS: There is a nice API talk on googletalks by a Java designer.
    PPS: The alternative to this Oracle suing is to move to Europe :-)

  22. Re:Black hole formation? on Massive Gamma Ray Bubbles Discovered In Milky Way · · Score: 1

    I'm sure I'm missing something, but I thought gamma ray bursts could occur as a result of black hole formation, which I thought was quite prevalent in the center of the galaxy. Wouldn't this be (or why isn't this) the top suspect?

    AFAIK the origin of Gamma ray bursts (GRBs) is not known yet (at least from the books I read, situation may have changed in recent years).
    This is about Gamma Ray "Bubbles" (not GRBs), which just means some structure emitting at gamma ray frequencies.

    Without having access to the article, I can only guess: Could those be the lobes/jets of our galaxy?

  24. Re:You CAN have their email address on Google Challenges Facebook Over User Address Books · · Score: 2, Informative

    The problem is that importing Facebook "friends" to gmail requires you to get access to their email address. Friends are in quotes, because Facebook friendship is more like shallow aquantances than friendship. Most of those people you don't want to share your email address with. It is a different thing entirely when people voluntarily give out their email addresses by signing up for Facebook apps, but in this case the email sharing would happen involuntarily.

    The email address is already visible in the info tab of the profile. This discussion is solely about whether a user can export all friends email addresses (that he can already see) *automatically*.
