    And you think the Sept 11 attacks are completely unrelated to (at least of of) those two wars you keep mentioning.

    Your comments spread across this thread are quite reasonable but here you fail both logic and common sense. Sept 11 attacks preceded the two wars often mentioned here and, unless you've been living under a rock in the past 14 years, you should know that the I war had nothing to do with Sept 11 while the A war was mostly a knee-jerk reaction to said attacks. Both shameful mis-uses of the US military resources and complete failures by any metric.

  6. Re:It's not surprising on YouTube Going Dark On Older Devices · · Score: 1

    Unless you wanted to settle for a lower performance display, you could not find a Plasma TV from Panasonic (the Cadillac of all TVs) without "smart" features. Even today, almost two years since they stopped making them, these TVs run circles around the current crop of LCD-based ones. Therefore, no, the "smart" features were not optional...

  8. Re:Going off the grid completeletly is stupid on The Myth of Going Off the Power Grid · · Score: 5, Interesting

    Why would they? The grid has no inherent storage capability into which to dump your day-time excess energy. It costs the power company to manage your bit of excess you're trying to dump into the grid.

    A few days ago I saw a nice graph showing PG&E's averaged output power during a typical 24h. It's a slanted U-shape, with the bottom somewhere around noon, then a sharp increase between 6PM and 9PM, tapering off after midnight and dropping slightly after 7AM. If they took away the solar-generated power fed into the grid by individual installations, the U becomes much deeper and PG&E projected that it will get deeper in the near future.

    The HUGE problem this energy generation/consumption pattern creates is that the baseline generators must provide the bottom of the U and not a Joule more. Everything else, especially the evening spike, must come from coal and NG power plants. Since in time the ratio between the peak and the baseline increases, more dirty and greenhouse gas emitting power plants MUST BE BUILT. In fact, all these 3 to 5kW solar installations make the greenhouse gas situation worse if the excess energy is not stored, which is contrary the feel-good but incorrect assumption about how all these solar panels help save the planet.

  9. Re:Keep digging you own hole on The Arrival of Man-Made Earthquakes · · Score: 4, Informative

    since the scale is logarithmic, you would need more than 3 million 2.0 earthquakes to dissipate the same energy as a single 8.5. So no, all these 2.0 or 3.0s don't make a dent in the probability of a giant 8.5

  10. the presentation is BS on Stanford Breakthrough Could Make Better Chips Cheaper · · Score: 5, Interesting

    The article follows the youtube presentation and the summary is, for once, accurate (i.e. does not introduce new errors).

    The trouble is that the presentation is utter BS. The GaAs devices are NEVER made out of a solid GaAs wafer; the process starts with a plain silicon wafer, on which GaAs is grown epitaxially. The secret sauce is, and always has been, how to minimize the defect density at the Si/GaAs interface.

    Such a wafer is more expensive than the plain Si one, but not 1000x more! Oh, and every purchaser would kill to get $5 8" wafers...

    Since the Stanford guys are no dummies, I guess that the announcement was deliberately made to sound ridiculous. For what purpose? Time will tell.

  11. Re:Sony should return to its roots on Why Sony Should Ditch Everything But the PlayStation · · Score: 2

    unfortunately these times are gone and won't come back. Consumer electronics carry too low a margin and there are too few potential customers willing to pay for quality but expensive(r) products for Sony to go back to their roots.

  18. Re: sorry, all my laptop batteries are dead on Using Discarded Laptop Batteries To Power Lights · · Score: 1

    You can't do that with a laptop battery pack. It would mess up the gas gauge counter (which, depending on the pack's firmware, could or could be not a recoverable event) and also could damage the cell-sensing circuits (during the initial assembly, there is a precise order in which the cells are connected to the pcb).

    Only 1S packs could be replaced this way, but these don't use the standard 18650 units and are not found in laptops.

    Silly, the overhead administering it is very, very low. Much lower than the private retirement funds.

    Are you really arguing against a system that helped old people live a little more decently? There is no denying that SS provided (and probably still does) a great social service.

  20. Re:Red Queen on How the Pentagon's Robots Would Automate War · · Score: 3, Interesting

    Sorry Bill, but this time you seem to be off mark. As a percentage of the federal budget, "Defense" is some 17.7%, to which I would add the DHS and NSA, for a grand total of about 20%. That's not spare change.

    When compared to the efficient way the other two agencies that command a large portion of the US budget (Health and SS) are run, it's hard to justify spending so much money on an endeavor so wasteful.

    In the end, the US military adventures in the last few decades have put the country in a tough place. Some of the actions have been unjust and for that the US is loathed by quite a few, some other created the impression of the US being the World Cop, therefore many expect it to act at a finger snap (e.g. in Syria and I still remember the debacle over *not* intervening in Rwanda). In the long run, this is a losing situation, no matter how many resources are thrown at it.

    My 17yo Civic has a complete mileage log for all of the 205k miles it traveled, i.e. how many gallons to full (I never do partial refueling) and how many miles traveled. If anything, the mileage is consistently better than what was on the windshield when I bought it new.

    In fact, looking at the numbers I can see the seasonal patterns (2MPG lower in winter), probably caused by my state switching to the winter blend (more Ethanol).
