  1. Re:Blu-Ray Delay? on Toshiba May Delay HD-DVD Launch to 2006 · · Score: 1

    HDTV in North America (and Korea) is 9GB/hour

    in MPEG2. In MPEG4, maybe 1-2G/hr :)

    But then the A/C switch wouldn't double as the Turbo button.

  3. Re:How long? on Excursions at the Speed of Light · · Score: 1

    But the light in front of you would be blue-shifted, and so the total power reaching you would increase.

  4. Re:Overheating issues? on AMD's New Venice Core Shows Overclocking Potential · · Score: 2, Informative

    This should be on the Slashdot front page

    In CMOS, Power=CVF^2 + Leakage. I^2R assumes a constant, non switching current and a resistive load. A CPU has neither.

  5. Re:Tri-LED? on Mitsubishi LED Projector: Small, Cheap, Durable · · Score: 1

    It may use the 3-chip DLP solution, one color per. But $699 would be a bit of a decrease in price over the last 3-chip I saw for $15000

  6. Re:Razored processor architecture on Cooling Down Hot Processors · · Score: 2, Informative

    Bzzt, actully you're both wrong.

    I'm also an EE. True, as technology improves the voltage is lowed. The Vt must also be lowered, thus increasing leakage. But for A GIVEN PROCESS is in the method described by GP, drain-source voltage has minimal effect on subthreshold leakage. The standard equation is, assuming Vds > 100mV

    Id_sub=Id0*W/L*exp[q(Vgs-Vt)/(N0*KT)]

    Id0 begin the current at Vgs-Vt and N0 being the subthreshold slope

    Well, you detector will also light up for most cordless phones, microwaves, ect

    The Federal Reserve prints more when they feel the econonmy can obsorb the inflation that an increase in total cash will cause. The goverment then can spend more money then they earned in taxes, will out a deficit.

    Actually, the biggest hurdle is that all the roads are on a 1 mile grid. and the road signs. And the markers. and those little white lines that police airplanes use to time you and give you a speeding ticket. Moving a road is a bitch.

    The international unit of the second is defined as "the duration of 9,192,631,770 cycles of microwave light absorbed or emitted by the hyperfine transition of cesium-133 atoms in their ground state undisturbed by external fields"

  14. Re:What about reliability? on On-CPU Peltiers From AMD? · · Score: 1

    Yes, except for the photons released by you monitor, all energy consumed by a computer ends a heat (and the photons, once they strike something). Charge is added to the gate of the transitor to turn it on. The charge is then dumped to ground to turn the transistor off. Think of it like lifting a log over your head. During the motion of lifting, you are doing work. No drop the log. All the energy in this process is now heat. Work was done, but the potential was released. P=CFV^2 + leakage + crowbar

  15. Re:The problem with stock options... on What The Bubble Got Right · · Score: 3, Interesting

    Of course, options do dilute the value of the stock. But the public knows this going in, the total outstanding options are stated in all reports. And the public votes each year weather or not to continue to provide options. If the company grows and stock price increases, everyone is happy. If the price stagnates, the options are worth zilch, are not sold and the market is not diluted.

    How do you calculate the cost to the company? You can't estimate the cost when the option is granted, it have no fixed value until the option is sold. If you wait until the option is sold, then the public has already bought their shares, with no way to know the expense that will be created when the option is exercised. Once you try to expense options, you may as well buy public stock, hand it to the employees but not let them cash out for 5 years. At which point you way as well just pay them more

  16. Re:You do realize on Battery Development Off The Beaten Path · · Score: 1

    Another reason which help computers evolve exponentially is that computers are used to design computers. With more processing power, an engineer can design a more complicated device.

  17. Re:Current VS. Voltage... on Rescuers Prep for Hybrid Car Accidents · · Score: 1

    When your dry, an meter will read 100K-1Meg ohm from hand-hand. There is another problem accossiated with the duration which is rarely mentioned. Most of this resistance is from the skin. Your internals are mostly electrolytic. As you hands begin to burn and the skin peels away, the resistance drops, and then you're in real trouble. Now only a few dozen volts can produce plenty of current to kill you.

    Its something like that. arm-arm current will pass thru the heart and stop it. arm-leg current will just cook your arm and leg.

    As far as I can tell, all the large supermarkets belong to one of two groups. Safeway owns Kroger, Abertsons, maybe Furrs. Tom Thumb and Dillions are together. Any card will work at any other member, though the cashier people throw a fit. Works good at the self checkout
