    "Difference needed in distillation steps between sugarcane and corn == zero."

    Sugarcane ethanol is distillated 3 times. But I don't know how many times corn ethanol is distillated. Anyway, the distillation of a solution with a bigger concentration of ethanol uses less energy than one with bigger concentration of water.

    "Very little processing is required to convert starches into sugars - one merely malts, or uses enzymatic processes directly."

    Moiling sugarcane is easier tough. But that isn't probalty that important.

    "It requires substantial energy input (above and beyond the bagasse) to make work."

    If you are talking about the plant, you are wrong. Sugarcane etanol plants work with the energy extracted from the bagasse, and still sell some eletricity to the grid.

    Now, if you are talking about the entire cycle, you are right. Sugarcane uses more energy in the form of fertilizer, tractor fuel, plant powering and transportation than there is on the bagasse.

    "On paper they are quite close, but in the real world MS is hated. Why this is should be the first priority at MS"

    I can spare MS the work... When Ubuntu fails, that is due to an error, and it doesn't call the user a pirate. When Windows fails to validate, that is dues to MS thinking the user is a pirate (and being quite verbal about it).

  5. Re:Cute, but no.. on Dragonfly-Sized Insect Spies Spotted, Denied · · Score: 1

    No, that is not an argument. Lack of power is an argument, as is the size of sensors. But it is not unfeasible because of control problems.

    You hinks it is hard controlling an helicopter because you are slow. There is no reason for a machine to be as slow as we are, in fact, they tend to have reflexes on the order of thousands of times faster than we.

    Also, depending on the design, it is quite viable to put a controler inside a firefly. With modern VLSI techniques, a very big (for our computer's standards) neural network is still very small, and still uses a tiny amount of power. Of course, such computer wouldn't be able to do anything else, and would take years to properly program, but it could very well controll a "bug".

    "The real threat is ignorance here."

    When you are talking about Linux, BSD, Solaris, etc, yes, it is.

    When talking about Windows, you have to clear all the way from browsers that execute arbitrary code from the web; files that execute automaticaly and the interface won't let you know beforehand; media that execute automaticaly, virus that spread trough text files, spreadsheets, images, video, etc; dialogs appearing all the time, trainning the user to agree to every one of them; And the list goes on...

  7. Re:GNOME or other wms on KDE Readies KOffice 2.0 As OpenOffice Competitor · · Score: 1

    One would need to configure KOffice to run with Gnome sound system. Yeah, ./configure would do it, but it is pre-compiled. I don't know if it can be changed after compilation, probably can, but it is probably quite easyer and less prone to errors to simply install arts.

    I am not contesting your overall knowledge on that area, but nanometer is nm, not nM (M is a SI prefixe, that stands for a 10^6 factor, m is an abreviation for meter). Your usage may be jargon of some knowledge area (or restricted to some geographical area), but is quite confusing.

    "Even if it isn't object-oriented, that doesn't change the fact that everything else in the kernel only cares that default_wake_function tries to wake up a thread - it doesn't matter how it works on the inside. All the other parts know about is the sched.h header file."

    Says somebody that, it seems, never tried that on real life.

    Good luck with any functionality change in sched.c. And if you really want to mess with the scheduler, not thread wake up, I really desire you a lot of luck to keep the information you need without breaking any unrelated part of the kernel.

    How does that system differ from one where you su the deamon for some user that owns no files?

    And, yes, one can break that set of precautions the same way one would break my precaution. And both were already done, and fixed, and done again...

    Chroot can be very usefull if your deamon can be buggy and corrupt something, but it simply can't protect against an intentional attack.

    "Also you'll often find chroot even on distros where there are no development tools to be found, which also encourages people to think that it's use goes beyond development."

    It is also usefull for system administration... For things like mounting a disk that is the root of some other system and using it (from a live-CD, for example), or avoiding incompatibilities on your libraries (like what the Debian-i64 did at their begining).

    What chroot is useless is for jailing a potentialy malign program. If it is not running as root, you simply doesn't need a jail, plain file permissions should be enough (and if they aren't, use another permission scheme). If it is running as root, the program can break it any time it want.

    "While these experts may have biases, they also have one thing journalists lack entirely - intimate knowledge of the subject at hand."

    Bias and knowledge are two facets of the same thing. One person can only not have a bias toward a subject if he/she has no knowledge at all about it. If you have any amount of knowledge you'll "leak" some of it when writting, and that is bias.

    But what people expect from journalists is bias. they just must stay away from unethical bias, that is ignoring what the facts and your experience leads you to conclude and publishing something else.

    But I can understand how, nowadays, somebody couldn't even know that multiplataform programming exists.
