  1. Re:Maybe it's a bad idea to have a "smart grid" on Securing the Smart Grid · · Score: 1

    Say what you will about the security or reliability of our current power grid, but it's got uptime measured in a whole shitload of 9's.

    Funny you should mention that. I had an outage at my San Francisco Bay area townhouse just this morning. (While I was reading the electric bill. B-) ).

    I'm in "rotating outage block 50" - i.e. I don't get rotating outages because I'm on the same chunk of the grid with some essential services. Like the local City Hall, cop shop, and fire station (which also went down), serving several miles of the major commute routes for this side of the bay. And maybe the west coast air traffic control center, which is just a few blocks away.

    Of course the rural "vacation / retirement cabin" in Nevada has outages every month or so, often lengthly. Power there comes from the nearest substation via several tens of miles of elevated wiring (at an altitude of over a mile in the passes of the Sierras).

    It will still be controlled by mega-corporations and will be able to impose the same restrictions as your current ISP. Simply replacing the physical media does not address the net neutrality issue. IMO, the only way this can be addressed is through laws which protect consumers and guarantee free (as in speech) and open access to the internet.

    How about, rather than regulating the transit itself, requiring the separation of enterprises that provide "content" from those that provide bit plumbing? That could be done under antitrust laws. Alternatively, downgrading the transport of competing services below one's own could be interpreted as anticompetitive behavior - antitrust again. Remove the business tie-in and you remove much of the incentive for using selective QoS for anything but tuning transport characteristics to improve handling of each stream type.

    And providing "Internet Service" with some pieces blocked or throttled, when the Internet originally deployed without such preferential transport, could be interpreted as false advertising. FCC doesn't have the authority? No problem. The FTC has all it needs.

    And I have worked for the federal government. You aren't even ALLOWED on a computer that can access the Internet until you go through security training.

    If it's anything like the security training I've seen in the private sector, it's a joke.

My favorite part was where the script - which already has your single-login-id-for-everything-in-the-company asks you to enter your password so it can check whether it's a "good" one. B-b )

    The question is: Why are they (government departments or enterprises) deploying Windows and related systems at all in a secure environment, rather than removing it entirely as fast as they can retrain their personnel? They're already known to be the most exploitable and exploited systems by orders of magnitude.

    Apple's iWork suite (Pages, KeyNote and Numbers) is rumored to be coming out at $20 per application, c.f. the current version at $80 for the bundle. That's a significant price drop but hardly a collapse (and could be self-compensating if it leads to more sales) ...

    Also: a significant chunk of the price of an application is the cost of packaging (media production, artwork, packaging and manual printing, package assembly, ...), order processing, shipping & handling, middle-man profit margins, and the like. Replacing this with electronic distribution and only one middle-man to pay off results in a much larger share of the per-unit price going to the application provider. So the price can drop considerably before it starts cutting into his per-unit gross. Combined with possibly larger sales due to the lower price point, along with the app store's access to a broad market, and he might make out like a bandit.

    Losers: Existing retail outlets, wholesalers, and the rest of the support network those costs paid for.

    A bigger hazard for the existing software providers is that electronic distribution drastically lowers the up-front sunk costs of bringing a product to market. This could result in increased competition from less-established and less-funded small developers.

And these aren't even bottlenecking the CPU itself... to be honest I don't know what the bottleneck is right now in some items... I'll open up the task manager... cpu utilization will be comfortably low on all cores, hard drive lights are idle so it shouldn't be waiting on IO... and the progress bar is just sitting there... literally 20-30 seconds later things start happening again... WHAT THE HELL? What are the possible bottlenecks that cause this?

    Might be thrashing or a task scheduler issue. Try a different OS on that machine to see if the performance changes, or try a similar machine configured with more memory.

    But it might also be the Von Neumann Bottleneck. If your working set - either data or instructions - is bigger than the on-chip caches, you get constant cache misses. It's like thrashing but between cache and memory rather than between memory and the swap partition.

    Ford now produces some of the best stuff on the road (including the highest mileage hybrid), and does better than even the best Japanese cars on reliability (even BEFORE Toyota started having speed control issues).

    They're also the only one of the big three that didn't need a government bailout/confiscation to stay open - let alone thrive.

  20. HOT engine starts. on Ford To Offer Fuel-Saving 'Start-Stop' System · · Score: 1

    How many cycles will a flywheel driving starter motor / solenoid setup last?

    The extra starts will be with a HOT engine, with the lubrication already circulated, cylinders and coolant warmed, fuel pressurized, etc. This is a MUCH lighter load on the starter, flywheel gear teeth, and bearings.

    TFA doesn't mention what will be used, but a spring / torsion system that captured the rotational inertia of the engine to stop it, and then used that stored energy to restart the engine would be great for warm restarts.

    And would be a real bummer if the engine happened to misfire on the start - at which point it would have to be cranked anyhow.

    Ford once worked on such a system, using block of rubber as the spring. This got the internal nickname "the rubber band engine". That was back before computerized engine control and it was retired undeployed due to a lack of reliability.

    Computer-controlled start was a holy grail among the engineers working on the first four generations of engine control computers (back when I was among them). But it's a hard problem to get reliable. So it only started appearing on cars within the last few years - perhaps after hybrids made solving the problem mandatory.

    I'm betting on the system being based on the regular starter motor for non-hybrids. The starter is already there, so only software (and maybe materials upgrade for longer life) is required, rather than the addition of a new mechanism. But it would be interesting if the RBE finally makes it to the big time.

    That small bit of sugar would be lost in the volume of sugar in a typical diet anyway.

    Not necessarily. It may depend on a number of things. Like what sort of sugar it is (sucrose? fructose? lactose? Is the person producing lactase?), when it's taken (empty stomach? blood sugar already low?), what the source is and how it's processed (corn derivative? Were the bacterial enzymes used to produce it purified out {fat chance}?), whether the person is allergic to any of the impurities, etc.

    For instance: A common placebo is, or once was, "milk sugar", i.e. lactose. A large part of the world's population does not produce lactase after infancy (and much of the rest drops production of it if not drinking milk regularly), so the sugar reaches their intestines (and the bacterial cultures growing there) intact. Presence of even a small periodic spike of lactose could swing the ongoing war among the various lines of intestinal bacteria in favor of the more benign sorts such as lactobacilis, shifting the pH and reducing the output of other bacterias' toxins.

    The Congress is there to determine the "will of the people" and the President to execute it. They are often at odds about what should be done - and it's the job of Congress, not the President, to make the call. The President, as the guy that has to implement the results, has significant input - enough to override a small majority for the opposite view. But if the majority is significant, and the mandate is Constitutional, he has to suck it up and carry out the will of the People as expressed through Congress.

    If the President is sufficiently charismatic to sway Congress to his position when it differs from that of a large majority of the population, he's not a great President. He's becoming an Emperor and/or Tyrant.
