    OK, not really, but how are you so sure it wasn't? I got my own education (partially) here on Slashdot while moderating, when I stumbled over a troll who mostly starts his posts "As one of the {original|first|...} {inventors|founders|programmers|...} {of|at|responsible for|...} <something connected with the article>, ..."

    > What am I missing?

    I'll start to list some of the things you're assuming, that are wrong:

    (1) The probability distribution of the individual bytes of the memory of your computer is uniform;
    (2) The individual bytes of the memory of your computer are independently distributed (i.e., there is no correlation whatsoever between the value of a byte and the values of the surrounding bytes);
    (3) If you could invent a "sufficiently arbitrary" method for selecting the bytes, it wouldn't already pay to use the address itself as the random number;
    (4) If you construct a float from independently uniformly distributed bytes, the distribution of the value of the float would be the distribution you are interested in (see IEEE_754);

    On the other hand, you are correct that this announcement is mostly a big yawn because:

    (1) High quality truly random numbers have been available via the Internet a long time (just not from direct quantum sources)
    (2) Hardware for generating large quantities of truly random numbers from various noise sources has been available for a long time
    (3) Hardware for generating large quantities of truly random numbers directly from quantum sources is now available (Quantis)

    Most of those legacy documents will not need to be edited, now, will they? So just converting them to PDF would be sufficient. I'm sure someone provides that service. I've even heard rumors here on Slashdot that Microsoft provides some kind of plug-in which can read most of the old Office file formats in the newer versions of Office. Luckily I don't need that. With my minuscule experience with trying to read old MS docs, I doubt it works in all cases (say, documents with embedded math formulas).

    Actually, now that I think of it, CAPTCHA's already pose problems to some (visual CAPTCHA's for the visually impared), but I wasn't thinking about that. I probably should have, since one can think of other CAPTCHA's where other specific handicaps would be a problem (human facial recognition comes to mind, for example; see Prosopagnosia).

    Since brain damage can cause very peculiar and specific cognitive problems, probably every kind of CAPTCHA will give trouble to someone. So I suppose there will be a variety of choices, just like there is sometimes an auditory choice given now.

    This is probably a logical choice for documents which the recipient doesn't need to edit, and might need to print. That would cover most governmental forms or informational reports.

    ODF would seem to be mainly useful (or at least required) for government correspondence with third parties like contractors. Actually, my impression of the Massachusetts decision was that the move to ODF is designed to enable the internal archive of government documents to be readable "forever". That archive possibly may not be open to the public, or perhaps will be opened to the public only after a certain period set in law (and not necessarily distributed via the Internet).

    As a lot of previous posters have noted, it will be a while before this technology will be in wide use to power cars, because of the need to provide a viable distribution infrastructure, and the fact that the rate at which the hydrogen is generated isn't fast enough yet to power a car.

    However, the minute I have a source of hydrogen I can use it to run a fuel cell to generate electricity to power my laptop or other portable electronic device. The rate at which I need hydrogen is a lot smaller. The heat from the fuel cell could be used to help run the reaction which generates the hydrogen (only needs 30 degrees Celsius).

    Yes, I agree that the GPP was not being realistic, but my reply had to do with your blithe statement: "Music is no different." It is. You continue to show exactly how much you don't understand about the difference in the continuation of your post. Or at the very least, you greatly deemphasize the differences in order to be able to view the situation as being parallel to your own.

    > I sell computer peripherals. Amazon makes about 15 points on my products; Best Buy makes about 50 points. This is out of my control,

    I somehow guessed that you would make some kind of analogy between music distribution and physical goods distribution. The retail margin is out of your control for two reasons, neither of which applies to the music industry. First, you are (I would guess) a smaller player than Amazon or Best Buy. The music industry, on the other hand, is an extremely powerful cartel with billions of dollars of income. Secondly, and more importantly, you have competition. Unless you sell some kind of very specialized peripherals which are heavily protected by patents, there is no legal problem for someone else to produce competing products, and Amazon and Best Buy can choose to work with your competitors if you don't agree to their terms. In the music industry, competition is prevented by copyright and the fact that demand is largely generated via advertising and the advertising is almost totally controlled (or was, until the Internet sprang up) by the music industry.

    > If, say, in selling computer peripherals my salary averages 9% of the sell-in price, it's not accurate to say that my employer gets to keep the other 91%.

    First of all, even though the music industry pushed through legislation in the US which enabled them to consider their signed musicians as employees (with respect to gaining copyright control over all of their work), they're not. Musicians are artists. They are the geese which lay the golden eggs. I'll admit that some employees in other industries are perhaps as especially creative in what they do as musicians in the music industry, but the vast majority of employees are not. Even if you don't agree with that, musicians are performers, and those other creative employees are not.

    > Warner Music managed to keep about 3% of their income last year. The other 97% all went to other people. If their average artist collected even a 4% royalty, they did better than the record company.

    When I look at WMG on Yahoo Finance I see a profit margin of only 0.3%! Checking the income statement there shows SG&A of 72% of gross income. For comparison, GE and Johnson & Johnson had SG&A's more in the line of 50% of gross income, and Microsoft was running 37%. Unfortunately, since this is a lumped expenditure which includes the entire payroll of WMG and all its advertising expenses, I cannot judge whether the big difference here is because the music industry is more heavily dependent on advertising, or whether its other expenses, like top executive salaries, are larger. Frankly, I'd guess that even though the music industry does depend on advertising, its advertising costs are offset by the monopoly it has on its product (e.g., radio stations are dependent on the music industry to provide them with content, because if they went elsewhere, the independent content they would obtain wouldn't be on MTV, and visa versa).

    > There are new and exciting ways to market products, such as the Internet

    And those ways were what I was actually talking about; in the case of the music industry, its product can even be distributed via the Internet (another difference).
