  1. reality distortion on Can Apple Find a European iPhone Partner? · · Score: 1

    In Europe, unlike in the US, Apple has the option of selling the iPhone through its own dealer network without a simlock.

    Apple has the same option in the US. I know: I only use unlocked phones on US networks because I don't like the default phone choices.

    The real problem with offering unlocked iPhones is that, unlike other smart phones, the iPhone is not fully programmable and that it is dependent on server support.

    Get a Symbian or Linux phone, a phone with MIDP support, or even (holds nose) a Windows Mobile phone; they may not be as pretty as the iPhone, but unlike the iPhone, they make sense unlocked.

    Regarding linux and C++ backwards incompatibility, please read these to get an idea why what you are suggesting is a bad idea:

    Those people don't know what they're doing. You'll always get some of those. There are lots of statically linked C++ binaries being shipped without problems. Yes, there are a few things you need to watch out for, so what? There are a few things you need to watch out for even when shipping supposedly cross-platform Java code.

    In any case, you're comparing apples and oranges anyway: Solaris is the equivalent of one Linux distribution. Is making software releases for Ubuntu any harder than for Solaris? No, it's not, it's actually easier because Ubuntu release and package management is far better.

    Please point me to a kernel trace toolkit that can replace the level of functionality found in DTrace. I'm skeptical.

    There are several general purpose tracing toolkits for Linux, and a number of special purpose tools. Whether they "can replace the level of functionality found in DTrace" is irrelevant; Linux also doesn't have Pacman built into the kernel, but that wouldn't mean that it were all of a sudden deficient if Solaris included a Pacman kernel module.

    What's in the Linux kernel is what users actually need and use, not what some overpaid Sun engineer dreamed up because he needed to justify his existence in the next annual performance review or because he wanted to make a name for himself at the next USENIX. As far as I'm concerned, "too much useless crap" is one big problem with Solaris.

    It's basic geometry and physics: in low light, there are only a small number of photons originating at each surface point and going into any particular direction. How many of those enter the camera depends on the total opening of the lens(es) you use. Detection efficiency of a good CCD itself is about 50-90%, and even normal CCDs are not that far below and already better than the human eye.

    I write these filters for a living. Please don't try to tell me how they work.

    I'm curious: you talking about the RAW conversion software in Blackbeltsystem's package or something else?

    In any case, whatever you write for a living, your descriptions contain several mistakes.

    Here's a simple summary of the key steps for converting raw images to RGB images (http://gauss.ffii.org/PatentView/EP1262917):

    There are a number of conventional demosaicing methods to convert a raw data image into a color image. Three main common categories of demosaicing methods include interpolation-based methods, feature-based methods, and Bayesian methods. The interpolation-based demosaicing methods use simple interpolation formulas to interpolate the color planes separately. The interpolation-based demosaicing methods include bi-linear methods, band-limited interpolation methods using sinc() functions, spline interpolation methods, and the like. The feature-based demosaicing methods examine local features of a given image at the pixel level, and then interpolate the image accordingly. The basic idea of the feature-based methods is to avoid interpolating across edges of features. The Bayesian methods attempt to find the most probable color image, given the data, by assuming some prior knowledge of the image structure.


    Note that interpolation or prediction are crucial steps; you cannot do reasonable demosaicing with only "fractional scaling" and "summing".

    Your description of human color vision is also bogus:

    From the human perception angle, your ability to perceive brightness is separate from your ability to perceive color (due to rods and cones.) Because the sensing mechanisms are separate, it is reasonable to say that any particular color also has an independent luminosity.


    There are several things wrong with that:
    • "Rods and cones" aren't used for color vision, only cones are.
    • There is no "separate" sensing mechanism for "brightness"; anything your eye determines about "brightness" in a scene is derived from the signals coming from the rods (night vision) or cones (day vision). In fact, the human eye/brain solves a problem very much like raw conversion.
    • Human vision is not based on absolute "brightness" or "color" at all, but on brightness and color differences.
    • A light source of any particular "color" has a corresponding "luminosity", but the "luminosity" measured by a single R, G, or B pixel does not let you predict the correct gray level value at that point.
    • Luma, luminance, luminosity, and brightness are distinct, well-defined concepts, yet you keep using them almost interchangeably. For example, "luma" is a weighted sum of gamma corrected components (a useless concept in the context of this discussion), while "luminance" is a weighted sum of linear components.

    The potential loss in color resolution is a pretty steep price for two stops worth of sensitivity

    First, there is likely no significant "loss in color resolution"; the resolution you're getting in the color channels right now is already only based on heuristics.

    Second, even if there were a loss of resolution in the color channels, you wouldn't notice it: you can't see high frequencies in the color channels.

  8. Re:Sacrifices color resolution: is it worth it? on Kodak Unveils Brighter CMOS Color Filters · · Score: 1

    The color image that results can be converted into a luma version by a simple fractional scaling factor applied to each channel, then summed

    That is not how raw conversion works; if it did, your 8M pixel camera would only give 2M pixel images. Actual raw conversion essentially uses heuristics to reconstruct the actual luminance at each sensor site, even though that information cannot be reconstructed in general from the measurements.

    The 8 Mpixel color image that comes out of your camera is already a complicated guesswork; in terms of real color information, it's more like 2-3 Mpixel, since there really are only 2 million complete RGBG cells.

    Making one of the RGBG cells into a "white" cell doesn't really change much of anything in terms of resolution: color resolution is still half what grayscale resolution is. And it does actually help with color accuracy, since having four different receptors lets cameras deal a lot better with fluorescent lights.

    This will also increase dynamic range slightly, since the "white" receptors are more sensitive than the RGB receptors.

    This looks like a very good thing overall, really.

    we had a brief refresher on the process of sublimation before we waded into the polar ice caps.

    Maybe you need a refresher on the phase diagram: the average surface pressure on Mars is just about the triple point (0.006 atm), which means that you get liquid water when frost (= pure water) warms up in the valleys. Furthermore, even at lower pressures, ice that sits on a surface and warms up will develop a layer of liquid underneath it, even if the surface sublimates.

    Where's a good corroborating source for that

    You mean like trying it out perhaps?

    Forgive me for being skeptical, but I don't think any reputable source for such a statement exists.

    Forgive me for being blunt, but any source that says that liquid water cannot exist anywhere on the surface of Mars is full of shit If you take ice, put it under 0.007 atm and raise the temperature to 0.1 C, the water will go through a liquid phase when melting; this isn't optional. It happens only in some areas and seasons, but it does happen.

    Anything that might break through to the surface will immediately freeze and sublimate

    Water that "breaks through the surface" probably contains significant impurities, lowering its vapor pressure and melting point, so it will stay liquid under a wider range of conditions.

    I also agree with Linus that ZFS is pretty much the only part of Solaris that is at all interesting. And, frankly, the main reason I'd like to see ZFS released under GPLv2 is that then Linux users would have a choice.
