  2. Re:Smart Grid is a scam on Electronic Armageddon, and No Electricity Either · · Score: 1

    Stuff that they've been miserably slacking on for the last 20 years order to pocket more short term profits while their infrastructure rots.

    The only thing the power companies have been slacking on is building power stations, due to economic and regulatory factors that are only partially in their control. Old transformers don't need to be "rebuilt" -- they require almost no maintenance and have life expectancies of decades. The technology for those hasn't changed in a hundred years. Power lines likewise have a low maintenance cost and the technology hasn't changed. Modernization for them has largely been adding power meters that "phone home" wirelessly or via a POTs line, removing the need for meter readers. That really is their biggest project, and it pays for itself quickly -- they're not slouching here to get "more profits".

    The Big Lie is that this modernization supposedly needs to be done in order for green energy technologies (eg grid interactive solar) to work,

    It's not a lie. If you're interfacing to the grid, they need to have a way to measure how much current you're putting on the wire, when, where, and be able to turn it off and on remotely, just like any other power station. And there are no regulations for how to do this in many municipalities. You think the cost they're talking about is the hardware? Silly you. It's the administrative costs.

    They might feel threatened because local generation obviously reduces the amount of energy sold, but it also makes that energy cheaper to sell and distribute because it smooths out the peak loads and reduces average current on long-distance transmission lines.

    Dude. power generation in just my state was 66*10^9 kWh in 2005, and represented a mere 1.8% of the total US consumption. The largest operating solar power plant in the world and manages a mere 60MW output, and takes up 25 hectacres of space. The Prairie Island Nuclear Power Plant, by comparison, manages 1,096MW output. For ONE of its reactors. Do you seriously think they feel threatened by the solar cells on your roof?

    But the power company has this line that it's making the grid "congested" as if the electrons are trying to go in **ZOMG!** both directions or something!

    Actually, it's more like they don't want a bunch of DIY greenies hooking equipment up to the grid incorrectly and causing problems that are difficult to trace and would likely be blamed on them, rather than the homeowner. You screwup the hookups, or the power feed isn't phased correctly, and your whole neighborhood goes dark because of your home improvement project.

  3. Re:De-spinning. Again. on Apple Dominates "Premium PC" Market · · Score: 1

    That's right. When comparing the price/value of computer hardware, the cost of software does not matter. Your $700 mid-range (or upper middle or however you want to measure it) hardware is $700 worth of hardware regardless of how much you spend on software.

    Hey, captain obvious called -- something about the "total cost of ownership"? I'm saying "premium" is a weasel-word. It's meaningless.

  4. De-spinning. Again. on Apple Dominates "Premium PC" Market · · Score: 2, Interesting

    Wow, what a clever manipulation of statistics. Somehow people who spend less than $1,000 don't have "premium" computers? How does that even work? I mean, I blow $1,500 on hardware but no software and it's "premium", but if I'm a poor graphic designer and buy a PC for $700 instead and spend the rest on Adobe's atrocious licensing fees, that makes me "not premium"? This doesn't say anything about "premium" or "not premium" -- this DOES however say a lot about how much people are willing to blow on Apple products. Answering why they're doing this is left as an excercise for the reader.

    I wouldn't personally implement a system like this, but the fact that it doesn't cover all potential circumstances doesn't mean it's worthless. I don't know why Slashdotters always have such a hard time grasping that.

    Because we're a bunch of purists who spend our time trying to find novel new solutions to esoteric problems the average person doesn't know or care about. We do have an easy time grasping it, but because of our own personal and professional standards, extensive experience, and training in information technology, we want the best. "Sorta works" just isn't in the geek vocabulary. And, I'd argue, that's how it should be.

    It's not security through obscurity; it's advantage through security.

    Pardon me for being a purist. But anything this easily thwarted also has no legal value, and my understanding here is that it's a punitive measure against the "leaker". If the document got leaked in the first place, chances are good the "leaker" in question can form an affirmative defense that a third party acquired the copy. Worse, if the algorithm is limited to a finite set of permutations, and anything that sticks to words and phrases is a very finite space (cryptographically speaking), the argument could be made that the document was leaked through a different source, run through the algorithm, and coincidentally matched the "signature" of the leaker's copy.

    It's completely bogus. If they want to keep data private, then use real cryptography, and validated software/hardware combinations that make the cost of extracting the data in a usable format more expensive than the data it's protecting. The military does it, as to certain businesses, and intelligence agencies around the world. The technology is there, it works, and it's real security.

    You're assuming it costs more money to police them than it does to kick off the heavier bandwidth users and then have a larger profit margin. 90% of the users pay for the 10% who use bandwidth heavily. Get rid of the 10% and profits soar. Ah, but you assume internet access is a regulated public utility and so they have to be fair and impartial? Te-he. Silly techie, trix are for kids!
