  1. Because everyone should be forced to go along with what California wants......

    That is how it works at the local level in California with the urban centers controlling the state. Why shouldn't the same apply to the nation?

  2. It's not ironic at all. The democrats weren't the ones that started the recount process, it was a third party candidate after reading a study that showed a marked discrepancy in votes between paper districts and e-voting districts. Regardless of the outcome of a recount, if a recount is what it takes for people to finally accept the results of the election then that's a good thing.

    Yet coincidentally Stein only selected states which could make a difference for Hillary. The Democrats made it clear to Hillary that forcing a recount would just look bad for them but nothing prevents them from using Stein as their stalking horse and apparently Stein is happy to go along with it.

  3. To clarify, I think far better of him than that, but I'm somewhat surprised he would be eager to fight for a group who treats him that way.

    They still share a common interest in defeating Trump or at least Lessig believes so. Sanders supported Clinton even knowing that she and the Democrats had cheated in the primary election against him. Like nations, politicians have interests instead of friends.

    And now you can get an Eneloop Pro AA in 2500 mAh capacities, with far lower leakage & more lifetime cycles than anything from those days. And D-cells go up to 11,000 mAh.

    The low discharge NiMH cells are pretty good and they have a higher capacity than any NiCd cell but they are still not as rugged and do not last as long as industrial (but not consumer) NiCd cells. The low discharge and high temperature NiCd cells which use a thicker and tougher separator seem to last forever.

    In my classroom, I have 1980s D size Radio Shack NiCad batteries that are 1.2V 1200 Mah. My students are asked to compare them to modern NiMh AA batteries rated at 1.2V 2600 Mah. We then compare them to roughly AA sized LiPo batteries that are 3.7V 2000Mah batteries. To compensate for battery size, we calculate volume as well as wattage.

    The bottom line is that if you have not noticed the steady progress of battery technology over the years, you are at fault.

    The battery progress in this case is obscured by marketing. Consumer D size NiCd batteries were almost always C size batteries installed into a D size case (the same goes for most NiMH D cells produced now) which was easy to verify by just feeling the weight. Even in the 1980s, you could buy true 4000 mAH D cells if you knew where to find them and were willing to pay the price.

    The standard AA sized NiCd cell in the 1980s was about 500 mAH and paste style high capacity cells up to 900 mAH were available even then.

    is a microphone. Both headphones and microphone share the same mechanism (using a voice coil). The microphone is more sensitive (as it generates small alternative current when the sound makes the diaphragm vibrate) ; and headphones do the opposite, its diaphragm vibrates when the device injects positive or negative current. Even a bigger speaker is sensitive enough to act as a microphone.

    This is only true for *dynamic microphones* which are tiny voice coil speakers. Most microphones are electret microphones which are a variation of the condender microphone and nothing like speakers but in consumer gear they are increasingly being replaced by MEMS microphones.

    I remember way back when, when Apple shifted Macs from 68000-based processors to the Power PC. Instantly, the fastest 68000-based Mac was the 68000 emulation mode of the Power PC. And native was faster still.

    As with a lot of semiconductor products they produced, Motorola did not make the effort necessary to compete using the later 68k processors so it is not surprising that emulation on a faster processor would yield good results. To be fair to Motorola, the 68k ISA was even less friendly to high performance designs than x86.

    Why don't laptop screens come in a 9x12-ish format? Because they are built to accommodate the keyboard, not the screen.

    You can use a solar panel as an infrared LED. It will produce light and heat, and may melt snow.

    I do not know why this would not work but I could not find anything online saying why other than the series connected reverse protection diodes (not the shunt diodes) which are commonly used. The minimum power would be higher than the output power but maybe that is not enough for snow removal.

    Let's see ...

    Forward Biased Panel Power 200 J/sm^2
    Heat of Fusion of Water 330 J/g
    Snow Density of 300 kg/m^3

    The number I come up with is about 1 hour per centimeter of snow meaning at least a day for the typical snow storm where I live but I suspect given the cold conditions that higher current could be used to safely increase that by 2 to 4 times.
