  1. I *cannot* possibly "suddenly jump".

    Again, you've posted several articles... all nonsense.

  2. Which specific sort of irony
    http://en.wikipedia.org/wiki/Irony
    would that be?

  3. You're simply blessed with indifferent ears and enough sense not
    to buy overpriced 'audiophile' stuff. (You know, even digital
    data must move over oxygen-free copper lines or be distorted.)

  4. RAID 1: Put in disk(s), have it/them synced, pull out disk(s),
    have a backup.

  5. You misread Martin on purpose, which tells us a lot about you.
    *sigh*
    The equivalent number of bits are the bits that encode the
    luminance for each pixel PLUS (at most) "an extra 2 bits of
    information beyond the luminance measurement depth at the
    pixel."

    With 11 bits of luminance any randomly picked bayer pixel contains
    at most 13 bits. A large group of bayer pixels (with 11 bits of
    luminance) actually contain well less than 13 bits (but more than
    11 bits), since their colours follow a regular pattern which is
    very easy to compress to a description.
    Martin isn't always gentle to people who wrongly believe they
    are right and who don't grasp elementary details about the things
    they proclaim as truth.

    But then he isn't paid to be that way.

    They don't care to explain to the n'th person that a perpetuum
    mobile is impossible.

    Would you have some proof for your claims[1], or are you just
    proclaiming them to be true, speaking ex cathedra by the power
    invested in you by God?

    No, liar, you're too stupid to grasp the fact that lenses admit only
    a small cone of light and block the vast majority of the light that
    comes in at incident angles. But that's just another example of how
    you really understand nothing of the real world.

    If I understand you correctly, you are postulating a microscopic
    capacitor device which when it is charged with one electron can be
    manipulated to have a potential difference of five volts.
    It might go from 0V to 2.7V or whatever. But then, presumably, you
    adjust the capacitor to get a final voltage of 5V.
    If the circuit has less than near-infinite impedance you will
    immediately discharge the capacitor. (What voltage do you need to make
    the electron jump on down the circuit? It depends on the materials.)
    If the circuit has more than this critical impedance there will be no
    current flow and whatever voltage there is will be unmeasurable.

    Any voltmeter will look like a short circuit and immediately discharge
    the capacitor (of its one electron). This is where Heisenberg comes
    in: you can either measure its voltage or know the location of the
    electron (i.e. in the capacitor) but you can't do both.
    We are now down at the quantum level and I think your question has
    become meaningless.

    Is voltage quantised? I suspect it may be.

    I seem to have not received this message to which you are replying.

    http://georgegraham.com/compress.html explains many of the problems
    with current digital recording. Well worth a read.

    So what does downtime consist off, what causes downtime.
    RAID is suitable for backups it might be less sutable for archives.

    Just joshing you, about your Usenet "handle" (the "Whisky" in it,
    was my target, to be precise).

    Oh OK then.
    But whisky dave is just a nickname I was given in a night club by a
    gril that
    needed to be able to tell one dave from another, she was already
    friends with a smelly dave
    and a violent dave, and as I was drinking whisky at the time.. and my
    entails are DW so WD
    didn;t see so bad. Also if someone recognises me in a drinking
    establishment and calls
    Hi Whisky Dave, I just say Yes thanks, but no ice and make it a single
    malt please ;-)

    And whisky is digital it's measrued in drams ;-)
    But I drink it in analogue measures....

    Hardware failures, viruses, et cetera.
    No; besides downtime reduction, RAID's prime advantage can be speed
    (depending upon the level involved).

    Its main pitfall, regarding backups, is that the user may restore a
    system, without knowing it was already corrupted by malware and/or
    other culprits.

    No need for it to be microscopic. Why should it be?

    I move one electron from one plate to the other, then adjust
    the distance. Yep.

    If a circuit has "near-infinite impedance" then it's not
    exactly a circuit.

    There are volt meters that do not need current flow, and in
    fact do not allow current to flow. Why should it look like a
    short circuit then?

    You do understand that Heisenberg isn't an either-or proposition?
    It's a statement of accuracy attainable.

    So of course I can get a voltage-to-some-degree-of-precision
    and a position-to-some-degree-of-precision. But I am not after
    the position (and "somewhere in the capacitor --- which can be
    easily as large as I want to make it" isn't exactly ... precise.
    Nor is 'somewhere along the conductors'.)

    To the contrary ...

    .... if it is quantised, then --- obviously --- not every voltage
    between 0V and 5V is reached even in normal conditions.

    And since charge is quantised and space is quantized and voltage
    depends on charge, area and distance in a plate capacitor ...

  15. No, *you* cannot. Voltage can. Of course, *you* cannot prove
    it cannot. *You* can not even explain how the voltage is supposed
    to rise gradually in the voltmeter.

    Go on stamping you foot. Dance, Floyd, dance.

    It's not my problem that you are unable or unwilling to
    understand.

    It's still not a viable >long term< backup solution, however. Too
    many things can go wrong, with such an on-the-fly approach.

  20. Shifting goalposts?

    Use a disk for every backup, in whatever backup scheme you prefer.
    It's not THAT hard ...
