  1. confusing arts and crafts on Paul Graham: Hackers and Painters · · Score: 1

    Graham is confusing the arts and the crafts. You probably need to be a decent craftsman to be a good artist, but you just being an excellent craftsman isn't sufficient. Painting is not just a skillful depiction of objects and people, it's about the human condition. Most software is not.

    borrowing features from Lisp (code metadata, auto boxing/unboxing)

    For just about every language feature, you are going to find some Lisp variant that had those features. But these particular features are not all that characteristic of Lisp and lots of other languages have had them, too. Since several of the JDK 1.5 features are exactly where C# differs from java (e.g., foreach, metadata, autoboxing), it stands to reason that the adoption of them in JDK 1.5 was in reaction to C#.

    And what the hell is wrong with that? Sun has been dragging their feet far too long. If Microsoft finally forces them to get their stuff together, all the better. Unfortunately, even the 1.5 changes still leave many very serious problems with Java unaddressed.

    being a better C++ (typesafe enums and parameterized types)

    Neither Java nor C# are a "better C++", they are completely different languages with a somewhat similar syntax.

    No, the way Sun has implemented it, it does not require modification to the JVM. That's a problem because it ends up being not entirely type safe across compilation boundaries, and because it is less efficient than it could be otherwise.

  6. use decision trees on Computationally Cheap Spam Filtering? · · Score: 1
    Most of the "Bayesian" spam filtering is naive Bayesian, which is really just an important-sounding excuse for using a computationally expensive and simplistic classification method.

    If you want computationally efficient methods for detecting spam, look into decision trees (search on Google for decision trees and spam filtering). If you set them up properly, they result in a sequence of simple tests like "Is this addressed to me?", "Does the subject line contain the word 'penis' or 'breast'?", etc. Like the so-called Bayesian spam filters, decision trees also give you probabilities. Properly trained, they probably work at least as well as Bayesian methods, and they should run a lot faster.

    There are a bunch of open source packages available for deriving decision trees from data. Furthermore, while computing decision trees is non-trivial, they can be converted automatically into a few lines of Perl or C code--no runtime libraries required.

  8. seems reasonable to me on Shuttle Politics · · Score: 1
    The shuttle fleet is an outdated, hugely expensive boondoggle for contractors. They shouldn't just be grounded for a while, they should be converted to scrap metal and be replaced by something better. I rarely agree with Republican representatives from Texas, but I think he is right on this one (even if he can't divide).

    As for this being due to Lockheed's campaign contributions, I kind of doubt it. I suspect Lockheed makes lots of money on the current shuttle contracts. Opening up this issue just risks that more of the development of the next craft will be done in-house, as contracting is more and more viewed as being responsible for safety problems.

  9. do not store in OCR'ed format on Best OCR for Technical Texts? · · Score: 1
    Scan your manuals in 300dpi or 600dpi grayscale and archive them that way. This will allow you to go back and use better OCR as OCR technology improves.

  10. we can thank Microsoft for this on Summary of JDK1.5 Language Changes · · Score: 2, Interesting
    Sun is finally rolling this out because of competition from Microsoft and C#. Until C# looked real, Java had mostly stagnated.

    Unfortunately, this doesn't quite make Java competitive with C# yet. Major missing features are:

    • JVM support for generics. Lack of JVM support makes generics not type-safe across compilation units, and it also makes them less efficient. The result is that the current generics implementation for Java is a stop-gap measure that isn't a good long-term solution. C#/CLR doesn't have generics yet, but Microsoft is planning on CLR changes to support them.
    • Lack of value classes. Value classes are essential for scientific programming, and automatic optimization cannot infer them reliably.
    • Lack of operator overloading. Again, that's essential for scientific programming. Some people worry that they lead to unmaintainable code. Of course, andy feature can be abused, but that's really a problem with overloading, not operator overloading.

    Also, Sun's patents on core Java technologies and the lack of a well-defined, open Java standard are still serious problems. The fact that Swing is de-facto part of the Java standard but that Swing is as ill-defined as the Windows API is another problem because it makes it hard to create open source implementations of Java.

    Wow, what a "great" idea with a long history:
    • The US can become just like the USSR. Oh, they didn't bother with the Internet, they just had people watch each other directly.
    • It goes great with current economic policies: people lose their jobs, then the government hires them to do this. Again, just like the USSR.
    • You can pay them even less if you stick them in prison first. Prisoners are already doing customer support for your airline tickets--why not have them watch you, too?
    • Surely, Walker has patented this, so it's a great example of entrepreneurial spirit.
    The idea of having lots of people watch lots of other people has been around for a while. Brin explored it in his book Kiln People. It may happen the way it is described in Kiln People: people deploying private web cams and making the images available.

  19. Re:Because free software is not planned on Why Open Source Doesn't Interoperate · · Score: 2, Interesting
    To make software interoperate, developers need to create interfaces before writing their software.

    Interoperability relies on standards that come from standards bodies. As long as the software conforms to those standards and works correctly, it interoperates. Interoperability with standards requires less planning on the part of the programmer because the standards have already been written by other people.

    Often no planning is done and developers start writing their code without a clear vision of what they want to write.

    Good. More software projects should start off with that kind of openness and willingness to adapt to changing circumstances.

    Even Linus is against the creation of standard interfaces internal to the Linux kernel. That decision inhibits the creation of a truly modular system.

    That part I fully agree with. But it has nothing much to do with "interoperability" because it is an issue within a single project.

    Also, Linus's stance is unreasonable: it is quite possible to define interfaces and yet to maintain the same flexibility that exists in Linux. The problems of the Linux kernel with modularity are cultural problems; technically and managerially, they are solvable if people wanted to solve them.

    We are not disagreeing on that, we are disagreeing on whether that's a good thing. You seem to think it is. I don't think so. US foreign policy should be aimed at improving the conditions in the rest of the world so that such attacks don't happen. But if US voters have the impression that they live behind an impenetrable shield (an illusion, but just as dangerous as an illusion), they aren't going to make the economic and political sacrifices to make that happen.

    Don't worry LA or New York or DC are taken out, trust your NATO brothers or friendly UN to... uh, nevermind I'm an idiot.

    Yes. The rest of the world has to trust the UN and organizations like NATO. The rest of the world has to live with the possibility that Russia or Iraq or North Korea or India can drop a bomb on them. Or, for that matter, that some US president declares them undesirable and drops a bomb on them. It's what gets people to negotiate and work towards better international cooperation. But the US wants to remove itself from all that and be able to send its military anywhere in the world with impunity, with no international checks and balances, and without the need to talk to anybody about it. And it's already happening: Bush has given the finger to numerous major international compromises that he didn't like for short term economic reasons.

    The only thing that makes this worse is that, in the end, SDI isn't even going to be effective: the US will behave as if it worked, but the US population will still be at grave risk. And enormous sums of money will have been consumed in the process.

    A far more reasonable and effective alternative is to invest all that money in international aid, education, and nuclear weapons destruction and control. But, of course, defense contractors wouldn't make much money from that.

    Recent history argues otherwise. NATO invoked Article V, but used it as an excuse to try to stop the attack on Al-Quaeda in Afghanistan.

    In complaining that NATO members may have tried to stop it, you are presuming that that attack was, in fact, necessary, justified, and effective. That was certainly not clear then, and it still is far from clear. It is something that would have warranted more discussion before going ahead, and there was no time pressure to rush into it, other than domestic US politics.

    In fact, NATO was, if anything, quite supportive of the US efforts and it was the US that declined more NATO participation.
