    By the time any of this technology could ship we'd probably have thought controlled car locks. No need for keys then. Presumably we'd still have tangible friends and enemies (as opposed to the virtual kind). Being able to find them by Google Earth would be useful. Of course, that could lead to a whole new twist on privacy & related issues (stalking, for instance).

  4. Re:It's not really possible. on Digital Camera Vs. Camera Phone · · Score: 2, Informative

    But with enough light, a small lens and sensor can take a good picture. You should look into the noise characteristics of digital imaging. There are differences between CMOS and CCD with regards to readout noise and pattern noise (and these are areas in which great improvements have been made), but they are not necessarily the worst noise sources.

    Photon noise (also called "shot noise") is intrinsic to the physics of photon arrival. The number of photoelectrons generated in a pixel is proportional to the number of photons incident on the pixel. The maximum number of photoelectrons (termed "well depth") which a pixel can contain depends on the size of the pixel. Bigger pixels means more photons and more photoelectrons for a given intensity of illumination. In a given time with constant illumination, a certain number of photons is expected per pixel, but the actual number in successive time intervals or in neighbouring pixels will differ. The standard deviation of this distribution is the square root of its mean value (photon arrival is governed by Poisson statistics).

    In a DSLR image detector, the well depth is at least 40000 photoelectrons (often much more) representing the saturation level. In a digicam, the well depth is typically 10000 or so, and is often less than this in cameraphones. At equivalent fraction of saturation, the shot noise in a 10000 electron well is half that of a 40000 electron well, but the signal is only one quarter as large. So the signal-to-noise ratio is twice as bad in the 10000 electron detector as in the 40000 electron detector.

    So, even with enough light, detectors with small pixels will produce noisier images, since their electron wells are small. It's a consequence of physics.

    The situation is often worse than that, since the cameraphones and small digicams typically have tiny optics. Even though their detectors are small, the lenses don't illuminate them very well (the Nokia N series is less bad than most cameraphones), and they must resort to boosing the readout gain. This amplifies shot noise directly. So, cameraphone and small digicams either need more light to reach "enough" than larger digicams or DSLRs, or they must amplify their noise even more to operate at the same light levels as DSLRs.

    Denoising in-camera or as postprocessing may make the image look better, but at the cost of losing image details with the noise artefacts. Heavy denoising produces a "watercolor" effect seen in many digicams.
  5. Cameraphone = phone + bulk != phone + camera on Digital Camera Vs. Camera Phone · · Score: 2, Insightful

    All of the subjects were motionless, so the test is useless for real-world situations, where shutter speed must be fast enough. I saw people trying to use camera phones at a sports event. The light was fairly good, but the results were pathetic blurs.

    And then there's the "vibrant colour" thing, which is seen to some extent in many digicams. Basically, the chroma has been excessively boosted, producing what photographers refer to as "Disney colour". It's a form of image distortion which can mask other flaws (especially combined with heavy denoising). As a deliberately chosen distortion, it has its place in artistic composition, but should not be the default.

    I have a Nokia "camera" phone, and after laughing at a couple of test images, I stopped trying to take pictures with it. If the target moves, the image is a blur. If the light is poor, the image is so noisy that denoising produces a watercolor. The tiny aperture means that the background is in focus, even at infinity. The only thing I can't complain about is bad bokeh, because it has no bokeh (and certainly not good bokeh!).

    For an always-in-pocket camera, I use the Sanyo C6, which has many compromises due to its compactness. However, in any lighting situation it will produce far better images than the Nokia, and does passable MPEG4 video also. For real photography, I have a Pentax DSLR with three flashes (wireless) and a dozen lenses.

  8. Re:Non-uniform heights on The Math of Text Readability · · Score: 1

    How does this law apply to punctuation and multi-part characters like i and j? Does the area to left of the space between the dot and stroke of the i count towards the 'volume'? There is often special handling for letters such as i, j, f. In essence, some combinations are not kerned, but combined into ligatures. A ligature is a single glyph of two or more joined characters. Take a look for combinations "fi", "fl", "ff", "ffl", "ffi", "ij" in properly typeset books (or even in your web browser). You may notice that the letters are joined, and not exactly the same shape as just cramming two single letters together. In fact, the "i" is often undotted.

    The "ij" combination is uncommon in English, but occurs often in some other languages, such as Dutch and Finnish. Arguably, the word "Fiji" deserves its own special ligature or special kerning.

    Since ligatures are themselves glyphs, kerning of ligatures with other letters needs to be defined for proper typesetting. For instance the space between "fi" and the following letter is not necessarily the same in "field" as in "fill".

  10. Re:Reasons to believe this is bogus on Are Mobile Phones Wiping Out Bees? · · Score: 4, Informative

    There also appears to be an obvious short-term fix to this, which is to breed the bees intentionally, either in captivity, or for the agriculturalists to hire an apiary to raise the bees near them, and harvest honey from the same crop. That's what beekeepers do: breed bees intentionally. Management of queen and drone production is an important job for spring and early summer, when the bee-keeper has decided how many hives to operate. The queens mate (lethally) with multiple drones all by themselves. Farmers, especially those raising fruits or other insect-pollinated crops, hire hives to be placed in their orchards or fields at the appropriate times. However, the bee-keeper is the one who gets to keep the honey; the farmer's benefit is a pollinated crop.

    The problem is for a healthy hive to lose its workers en masse. The queen is still producing eggs, but without mature workers the hive is doomed. It appears to be unrelated to the varroa pestilence which spread from Europe into North America in the 1970s and 1980s, and devastated many bee-keepers' livelihoods.

  23. Meltdown on gear change on Dept. of Energy Rejects Corn Fuel Future · · Score: 1

    For large motors, it's hard to incorporate discrete gears. On a gear change where the ratios are significantly different, the clutch/transmission would not be able to absorb the energy dissipated unless it's very large. So either the diameter of the clutch plate must be enormous, or the ratios must be very close. Continuously variable gearing is also problematic due to heat dissipation, unless the power conversion is _very_ efficient. Diesel-electric coupling is a pretty good solution for large motors, since no gear changes are needed.

    Perhaps a PC could be given three prices, so the purchaser has a proper choice:

    Clearly, options 2 and 3 would be lower cost than option 1. I expect that options 2 and 3 would be similar in cost, even if the Linux option included a DVD with the distribution, drivers, and a collection of FOSS packages. The trade-offs in pricing would be visible in a way that customers might understand, although the crapplet collection would probably be described as "bonus enhanced-value mega-cool selected premium packages" to mask its negative value. People who truly want Windows might opt for the reduced-crap option, even if its price is higher (especially if they experienced the crapplet search & destroy obstacle course after an earlier purchase).
