    I've come up with a wonderful algorithm. What you do is keep a 'sum' number, and randomly generate a 'shift' number by shifting the original bits n times, then add this number to the 'sum' number. It can be repeated as many times as you want, with randomly generated n's. I was trying to come up with a good name for it, and all I thought of was my daughter, Multi...

    When you fold something in half, it becomes twice the thickness, so 10 folds gives 2*2*2*2*2*2*2*2*2*2 times the thickness, or 2^10 = 1024. I was pointing out the fact that he wasn't trolling, he was simply mistaken.

    I've always heard it used in multiplication, but if you take '10 fold' to mean '10 folds' then it would be exponential, i.e. '10 fold' = 2^10 = 1024, which I think was the mistake made here.

    The backup isn't important, the real question is 'Who has the data'.

    The loss of the data isn't important, the gain of the data by people who probably shouldn't have access to banking information and home addresses is a problem, though.

    Once you have bank account numbers, presumably with the bank involved, I assume it would be trivially easy to phish people by sending emails with correct bank names and REAL names, so large amounts of login credentials wouldn't be too hard to gain with the rest of this information, sadly.

    Of course, this is assuming that there isn't enough data lost to allow people to clean out the accounts.

  12. Re:Advantages? on The Last DC Power Grid Shut Down in NYC · · Score: 1

    It's certainly more interesting to ponder all this than what you're doing, which is to fold your arms and proclaim my 'computer is running on DC power.' You sound like you're trying to tie philosophy into a technical discussion.
    If you've taken a basic circuits class, you'll note that almost every IC will take in a (for simplicity) +5V power source through the circuit and place that into a 0V ground. This is always present, whether a clock signal is present or not to trigger a change in the voltages within the circuit, the +5V and +0V are required to maintain the state of the system (assuming volatile components, since non-volatile components require very little if any power to maintain)

    In almost every system you describe, the AC voltages have a purpose of triggering a change in the circuit, rather than powering the circuit. If that AC voltage suddenly gets flattened to 0V, the system would halt, but no state information would be lost. In this sense, you are correct that your computer would 'run on' a high frequency oscillation, however if the signal was suddenly stopped, no state information would be lost, the circuit would simply perform no calculations. In this sense, I am correct that the AC signal is a non-essential, though very useful, component of a computing system. Should the 5V power source be eliminated, all information would be lost, and the AC signal would 'open' and 'close' the gates of transistors with a 0V difference across them (producing no change). Thus, the computer 'runs on' DC power.

    In so many words, the clock is a signal, not a power source.

    If you would prefer to debate what constitutes a computer, in your Palm III backlight example, I'd rather not get into that, as it's a rather inane debate.
  13. Re:Advantages? on The Last DC Power Grid Shut Down in NYC · · Score: 1

    Actually, your computer is running on DC power, and the components are triggered (not powered) by DC. If there was no DC the clock signal wouldn't power a whole lot.

    but it uses electricity which comes from coal or oil, to produce hydrogen that contains less energy than the oil you had to burn to make it Actually, TFA states that the process could be self-sustaining (assuming free plants) with respect to electrical output.

    Guess what -- this working microbial fuel cell takes C,H,O in as vinegar or cellulose, and outputs H2 and CO2! Do you really call that 'carbon neutral' as a fuel source? It's still dumping CO2 into the atmosphere, just less of it per Joule of useful energy. Yes, I do call it carbon neutral. The plants take in C02, H20 and E to create vinegar and cellulose, and due to thermodynamics, plants can't create more H20 and C02 than they take in; so by definition it's carbon neutral.

    It would be so that the form would always be filled out correctly, and only once.

    What if someone wanted to change their vote midway through voting? They would probably end up scratching out the candidate they had voted for rather than request a replacement ballot as they are supposed to.
    In this instance, the machine would act as a quick total verification (to allow the hand count to be quickly validated) as well as a type of file buffer, so that people could vote more clearly for whom they desired.

    most will draw the line at saying the patent action is a good thing, because we don't know who might get hit by it next. Microsoft can write off a $5M loss on patents about as easily as they can write off Ballmer's lunch, but while $5M might not be much to Microsoft, I'm wondering if they knew what they were doing by handing the company money; After all, it's not particularly to Microsoft's advantage to kill a patent troll, they'd be doing their competitors a favor.
