  1. Re:Hrm... on FCC Wading Into Digital TV Quagmire · · Score: 1

    If there's enough demand for digital TV, it will happen.

    hat's just an irrational faith in the market system. There's a chicken and egg problem here. What broadcaster is going to give away his market in order to champion a switch to a digital system.

    All I want is compatible standards so that I can watch a movie in wide screen at home.

  3. Re:Can anyone tell me wtf a Klein bottle is? on Get an ACME Klein bottle! · · Score: 2

    Every ordinary continuous, unbroken surface embedded in three dimensions has an inside, an outside and encloses a definite volume. A Klein bottle plays a trick by using a 4th dimension to connect the surfaces in a way analogous to a mobius strip (a two dimensional surface twisted in the third dimension so as to have a single side) and so that the inside surface (and inside volume) is contiguous with the outside surface (and outside volume).

    For example, you can use a continuous, unbroken surface to keep a toxic gas from poisioning your pet hampster, Hemos. A sphere, a cube, a cylinder, a torus, a duodecahedron -- pick your favorite shape. Just don't use a Klien bottle. There's nothing but the 4th dimension keeping the stuff on the inside from the stuff on the outside.

    A Klein bottle differs from an ordinary bottle in that an ordinary bottle is not a continuous surface -- it has an edge.

    It's not that it has zero volume but a continuous, unbroken surface.

    Actually, a Klein bottle does have zero volume. Volume is a measure of three dimensional space enclosed by a continuous, unbroken surface (such as a sphere). A Klein bottle actually encloses no space (the inside is contiguous with the outside) and has no volume. That is really the joke of the page.

  5. Re:Electric cars on Get an ACME Klein bottle! · · Score: 2

    it's an engineering mistake to design something with more than needed!

    Bullshit! Good engineers design with margins -- margins for peak performance, margins for reliability, margins for safety.

    Why do we need computers in cars?! fuel injection is *NOT* that complex. Oxygen sensors?! WHY?!?!?!?!?!? are you going to be driving the thing in the MOUNTAINS?! You'll be at the same elevation for practically the entire life of the car!

    Computers in cars satisfy two requirements -- emissions and efficiency. Federal law (and environmental responsibility) requires clean cars that use a minimum of fuel. Consumer demand and safety requires a certain amount of performance at least from time to time. A computer allows the fuel/air mixture to be continually adjusted to meet these conflicting needs for a relatively small cost per vehicle. Rather than being a rantable offense, it's actually a fine application of engineering principles of which you seem to be woefully ignorant.

  6. Did you say backup? on The CIHost Saga Continues · · Score: 1

    Also remember to test that you can restore from backup. I worked at a company with an elaborate backup plan incorporating daily, weekly, monthly and annual backups with some onsite and offsite storage of backups. But they had never tested recovery. When it came time to restore some files, they discovered that the backups were unreadable. That is not the time to learn this.

    From the O'Reilly book Practical Unix Security:
    When was the last time you backed up your computer?
    a. today
    b. this week
    c. this month
    d. this year
    e. never
    f. My computer is already against the wall and can not be backed up any further.

    If your answer is a or b, good for you. If your answer is c, d or e, put the book down and back up your computer. If your answer is f, keep reading; everything is just fine.

  8. Re:Lawyers & Technology v. Politicians on Techies vs. Laywers & Judges · · Score: 1

    When we litigate, of course, we get experts to tell us what's what. In court, it's all about the duelling experts. It is these experts who teach the lawyers what they need to know before the court appearances, and who also educate the judge during the trial. If you're a personable guru with people skills and can tell a good story, you can make big bucks being an expert witness, let me tell you. All this to say that during a trial, the lawyers will be informed and up to speed as best they can be, as they will be prepped by the experts.

    I think that part of the problem is that the experts don't get involved until the case is nearing trial. At that point, it becomes "Let's find an expert to support our [lame] case." rather than "let's see if the technology supports the claim that we want to make."

    Fundamental misunderstandings of HTML linking, the copying inherent in network operations and how the OS runs programs, even such basic differences between "methods of operations" and copyrightable expressions in the Lotus/Borland case.

    The real problem is that the little guy has already been hurt by the deep pockets before it gets to this stage.

    No. The original DeCSS program was a Windows program, but the purpose for writing it was to get an unencrypted VOB file on a hard disk for developing the player software while udf filesystem drivers were still in development. Shortly afterward, a Linux version of CSS was writted so that the intermediate step of unencrypting the file under Windows was unnecessary.

    If I were TH's character, I would have driven off with Helen Hunt and not looked back. This guy was driven to survive and get off the island.

The wings were a minor feature but perhaps one that gave him hope for the sail he improvised.

    She said he was "The love of my life." But she waited something like a year before she got married and had a kid? I'm sorry, but it seems that she gave up on him too easily and then regretted it. It could take a lifetime to get over the loss of the love of your life, but this culture dosn't want to recognize that. This movie wasn't about to buck that piece of cultural "wisdom".

    To be completely accurate, Pope Gregory XIII proposed his calendar reform in 1582, hundreds of years before Napoleon was born. The pope in office when Napoleon ruled was Pius VII.

    From the Brittanica article on the calendar:
    The French republican calendar was short-lived, for while it was satisfactory enough internally, it clearly made for difficulties in communication abroad because its months continually changed their relationship to dates in the Gregorian calendar. In September 1805, under the Napoleonic regime, the calendar was virtually abandoned, and on January 1, 1806, it was replaced by the Gregorian calendar.

    I've very concerned about this statement. It is my understanding from reading the livid-dev archives that the disk keys are stored on a sector that the hardware will not read until the CSS authentication process has been begun. See this message for example.

    Does a private individual have the right to make a program that executes a proprietary algorithm, if they used a clean-room method to find this algorithm?

    It is my understanding that clean room implementations are done to avoid violating copyright on code that needs to be emulated.

    For example, when the IBM PC BIOS needed to be emulated, clean rooms were set up so that the people seeing the code where not the same people writing the code. That way, they wouldn't unintentionally copy the exact expression.

    One of the CSS documents purports to be a clean room specification. Someone could write a C program from that description, but I don't think it would help in this case where the claim is misappropriation of trade secrets.

    Sure. Don't show them to anyone.

    Here's an important question: can you sue for damages, a person or group who released a product using your patents, if they gave that product away for free?

    Yes. Patents grant exclusive control over any process. They are stronger than copyrights in that even independantly developed implementations are covered. Patents are also for a much shorter duration than copyrights. Patent holders can sue for royalties from anyone utilizing their patent.
