  1. Re:Lack of competition on Intel Skylake Bug Causes PCs To Freeze During Complex Workloads (arstechnica.com) · · Score: 1

    Simulation testing is very difficult. It is many orders of magnitude slower than the actual device. At some point, you have to ask "should we do 2 more months of simulation on this or just spend a million $ or so to fabricate some samples with the newest tiny geometry?" So you fabricate, find 50 errors missed in simulation, fix those and start simulations again. Fabricate again (whoops! there goes another million) and find that there are flaws caused by the fixes, flaws hidden by the previous flaws, newly discovered flaws, and yet there will still be flaws that won't be easily found, or found soon.

    With each new fabrication the pressure builds to market a chip that at least have known bugs that can be worked around. Customers want faster chips and more features, and they're somewhat willing to work around bugs to have what they want. Rather than wait for another multi-month cycle that angers fans and customers and costs money, the manufacturer ships and crosses its fingers. We're human beings, and we're doing the best we can, which is very good.

    Let's say I'm now lighting a room with a 100 W incandescent producing 1650 lumens, then I replace it with a LED lamp requiring only 21 watts for the same light. I've saved 79 watts.

    Years from now, I replace that with new tech using only 5.2 watts. I've saved only an additional 15.8 watts. The impact is nowhere near the same, 79 versus 15.8

  4. Re:I like my LEDs... on Nanotech Could Make Incandescent Light Bulbs As Efficient As LEDs (sciencemag.org) · · Score: 2

    Take a CD or DVD and hold it so you can see a diffraction spectrum. Incandescents have a continuous spectrum, and so do the LED-phosphor bulbs used for room lighting, although the latter is likely to be stronger in the blues. Every fluorescent I've seen has actual gaps in the spectrum.

    Although it's a start, CRI is not a good measure; it's possible for instance to combine several monochromatic sources to produce a CRI of 100. Something better is needed.

  5. Re:What's the lifetime of the bulb? on Nanotech Could Make Incandescent Light Bulbs As Efficient As LEDs (sciencemag.org) · · Score: 1

    There are two related factors that will be better for the new incandescent bulb.

    One is "notching" that conventional bulbs are prone to, which is related to the electric field and crystal structure in the tungsten filament, which will be reduced in the new design. (I'm not sure of this claim, sorry.)

    The other is that any thin region of the filament will tend to run hotter in the conventional bulb, hastening the sublimation and further thinning in that region. This effect will be reduced in the new design because some of the heat comes directly from electricity and some from reflected IR.

    Note, however, that the new design uses a flat filament that will be very much thinner than the conventional filament wire, and that unexpected problems are likely to appear.

    Most people can't see colors by moonlight; it's too dark for cones to work well.

  7. The push to make more efficient LEDs has been going on as long as LEDs have been a commercial product, about 45 years now. Government pressure has sped up the process for useful LED home lighting somewhat, but basic LED efficiency not so much.

  8. You can buy incandescent bulbs designed to work at 130 volts nominal, which means they'll last about 3x as long as a bulb designed for 117-120 V. They don't sell very well; consumers have chosen wisely by buying incandescents with a lifespan of about 1000 hours.

    I mean, the companies involved are the same ones making lightbulbs to this day.

    Westinghouse got out of the consumer incandescent market decades ago. GE stopped making conventional incandescents more recently; GE (political corruption) is part of the push to make them illegal so that GE could sell more expensive halogen and CFL lamps.

    I think a cochlear implant will do the job, provided that you still have enough nerve function to hook the device to. It's not cheap, requires professional adjustment after an operation, and the quality is poor. At most you get 22 narrow frequency bands and have to interpolate for intermediate frequencies.

    The technology is improving, but progress isn't particularly rapid.

    Writable disks are more expensive than stamped disks, and aren't as durable. Stamped disks are difficult or impossible to individualize (AFAIK). I suppose it would be possible to laser-write something individual on each stamped disk, but even that would add cost that somebody would have to justify to the accountants. Resold disks complicate matters, and disks sold in countries that don't respect copyright or otherwise flout the law don't provide the manufacturer any protection.

    Still, it seems like a good idea.

    Piracy provides consumers with a mechanism to acquire something that the author prices outside of what it is worth,

    Although "worth" can be objective (Nails are worth a lot because they hold my house together.), many uses of worth are subjective. Your claim leads to the demand "I find the author's work to be worthless, therefor he must allow me to copy it for no charge."

    Just as a person owns the product of his physical labor and has the legally protected right to keep or trade that product, so he has the ownership right to the product of his mind and (within certain limits) that right is legally protected. The BASIS of intellectual property is the individual, not societal utility. You don't have a right to what I created, except on my terms, and I don't have a right to what is yours.

    The fundamental virtue of human activity is to provide for your own life. By taxing efforts to provide for yourself, income taxes discourage productive activity, so they are destructive and immoral.

    Government's primary responsibility is the protection of its citizens lives and the means by which they provide for themselves, which requires that the government should protect the fruits of their productive efforts known as property. Add to that a means to handle wrongs (a court system) and the government's responsibilities are covered; and that is the proper limit of "social services."

    A basic principle of justice is that "you get what you pay for and pay for what you get". The government protects your life, you pay a head tax. The government protects your property, you pay a property tax. Use the court system, pay court fees. The government has no just basis for taxing income.
