  1. Re:Help me out here a little... on Utilities Battle Homeowners Over Solar Power · · Score: 1

    One should note that there's no real "storage buffer" in this system. Oh, there's some high-power capacitors in places, and you get a little bit of play because of the natural capacitance of the lines, but, with in a fairly tight margin, income has to equal outgo at all times. There's no "storing it for later" past a few minutes. This means the utility is constantly managing their input, turning on generators when they're needed, turning them off when they're not, which can be tough because a lot of that equipment can't be turned on or off on a moment's notice--and it gets a lot tougher when they don't control a significant amount of their inputs.

    The answer is simple. He's taken dozens, if not hundreds of measurements. The odds are in favor of one of the measurements turning up a correlation by chance. The odds against this particular measurement being by chance are 19 to 1--but he's selected it out of the group. The chances that one of *any* of his measurements would show such a correlation by chance are quite high, and he's just selected out the one that got that correlation.

    We the People petitions are meaningless. Get enough signatures, and you'll get a signed form letter from the White House. Nothing actually happens.

  6. Re:Note to the terminology-impaired on Chinese Hacker Group Targets Air-Gapped Networks · · Score: 1

    So workstations on an airgapped network can never get software upgrades?

    Correct. The system would have to have its airgrapped status stand down temporarily to perform the upgrade. Which is one reason that upgrades on such systems are rarely done.

  7. Re:Note to the terminology-impaired on Chinese Hacker Group Targets Air-Gapped Networks · · Score: 1

    Yes it is. Otherwise, you would never get a single computer on that network. At some point you *have* to bring something into the area.

    Correct. And at that point, the system is not airgapped. It will be airgapped once installation is complete and system sealed.

  8. Re:Note to the terminology-impaired on Chinese Hacker Group Targets Air-Gapped Networks · · Score: 1

    Sure it is. An "air gap" is a network configuration- e.g. there is no wire connecting the network to the outside world.

    Wrong. An "air gap" is a *network and system* configuration. There is no *nothing* connecting the system/network to the outside. If there isn't air between hardware and *any* outside media, network or otherwise, there isn't an air gap.

  9. Re:I wonder... on Chinese Hacker Group Targets Air-Gapped Networks · · Score: 1

    And the answer is, they are not air-gapped during the update procedure, which thus must be carefully controlled Updates tend not to happen often in such evironments, for exactly that reason.

    I once asked a prof how I was supposed to know which integration formula/identify I was supposed to be using. He basically said "after a while you just know which ones". Because, apparently, there are no teachable rules for this, just hand waving guidelines which are supposed to make sense at some point.

    Well, yes. Integrating an unfamiliar type of equation is one of the tougher things to do in math--in fact, most of the time it's not possible to integrate a comoplex equation symbolically, which is why we do numerical integrations.

    Doom might be a little hard to find (but not impossible), but you can get Secret of Monkey Island from Good Old Games. It's a remake (still kinda old even so), but very faithful.

    Well, that's the problem. With a few notable exceptions, the game industry doesn't give two figs about being taken seriously artistically. They just want to make as much money as possible.

  16. Re:Sensors wrong on Planes Without Pilots · · Score: 2

    Theoretically, it can do that. Practically, somebody has to figure out all the possible emergency options ahead of time, along with how to rank them by desirability, for the computer to choose one. An experienced pilot can reason through his options based on his experience and knowledge of the actual situation facing him. A computer has to be preprogrammed with all possible options and how to rank them by someone who has to imagine all the possible situations before they happen.
