    Bravo couchslug, for saving me the trouble of writing up a post. My thoughts exactly.

    Additionally though... It's not JUST that geeks are held back. Even people of average intelligence are allowed languish, while being forced to memorize the basics, over and over again, with just a couple twists the second and third time around.

    eg. From 6th grade on through high school, I was taught introductory algebra every year... That's 7 years running. In 6th grade it was represented by blank spaces in equations, rather than Xs, but exactly the same otherwise.

    It's some horrible combination of unbelievable grade inflation, combined with the concept of grading attendance and volumes of busywork, which has made the US secondary school system fail society so miserably.

    I see no reason to believe increasing the amount of time spent in school will reverse this, nor can I possibly recomend foisting even more of this mild form of torture on anyone's children.

    The point you've responded to states that two kinds of regulation (preventing companies from offering catastrophic coverage, and preventing companies from offering policies across state lines) are bad.

    The parent was an anti-regulation shill. Nothing more. It's a shame you can't see that.

    C) These problems exist currently, the two classes of regulation in the quoted point have nothing to do with recision, and I can see no reason why it would cause recision to increase if those two classes of regulation were removed. If you can find one, state it and it'll be worth discussing.

    One of the two was "low-cost catastrophic-only insurance". The very idea is LAUGHABLE. The fact of recision directly counters this idea. Even the "high-cost" general-coverage insurance plans face serious issues with recision. There's no way a lower-cost option is going to somehow do better.

    the insurance company must be liable to pay some sizeable percentage of what you paid

    If so, you're undeniably better off NOT getting insurance. Put that money in a savings account and earn interest on it. Then you get more than 100% of the money you put in. AND for the 99.9% of the population that never needs it, you also get all your money BACK.

    Health insurance ONLY WORKS if the health insurance company will be required to pay your medical bills, no matter how expensive they get. That's exactly why you're paying them... for INSURANCE against the very unlikely event that you end up with astronomical medical bills.

    Do doctors or lawyers or engineers ever argue that their service should be free?

    Both doctors and lawyers most certainly do. There's a very tentative balance between charging for your services to stay alive and well, and doing charitable work.

    A great many doctors do a LOT of charity work, including traveling to foreign countries to treat people who can't pay anything. In fact, accepting Medicare patients tends to be a loss rather than a profit for many doctors, but most will still accept those patients.

  7. Re:makes sense on The Fresca Rebellion · · Score: 3, Interesting

    Among the major options that many right-leaning politicians in America have been pushing is tearing down regulation that has prevented insurance companies from offering low-cost catastrophic-only insurance, and removing regulation that prevents cross-state offerings for insurance. Those two items alone would greatly expand the choices and lower prices across the board for insurance.

    Look up recision. In the private health insurance market (ie. not through your employer) if you start racking up significant medical bills, you have a ~50% chance that your insurance company will find some excuse to cancel your insurance coverage on any technicality they can come up with.

    THAT is what an unregulated health insurance industry will get you. It's cheaper to only insure people who won't get sick, so everyone will find some way to eliminate those with any chance of major bills, or worse, discontinue their insurance for no reason when they actually start to need it.

  8. Re:Q. What is Theora? on Theora 1.1 (Thusnelda) Is Released · · Score: 1

    Possibly - so long as you don't want any audio with your video.

    MPEG-1 Layer 2 audio is patent-free as well. Sisvel/AudioMPEG has stopped asserting patent rights on the technology some time ago now.

    It's only the slightly more recent MP3 (MPEG-1 Layer 3) which will get you into patent trouble... Which is a non-issue, since from the very beginning, just about EVERY hardware device or software player made that supports MPEG-1 video also supports MPEG-1 Layer 2 audio, but usually NOT MP3.

    Encoding and decoding complexity for MPEG-1 is... actually going to be quite close to MPEG-2.

    Complexity, and everything else about MPEG-1 is going to be IDENTICAL to MPEG-2. MPEG-2 IS MPEG-1, with just a couple features added, like support for interlaced video...

    h.264 also offers quality improvements at *every* bitrate

    At high bitrates, the improvements are absolutely nominal. It's a fundamental law of perceptual encoding. Here's my /. form-letter response:

    You're also welcome to look-up subjective benchmark comparisons of H.264/AVC and MPEG-2, which, even if they've biased the test to use old and poor quality MPEG-2 encoders, at the very least, will demonstrate the diminishing returns of H.264/AVC at increased bitrates/quality.

    And finally, there are inherent limits that audio and video codecs cannot possibly exceed... For audio, that limit is called "Perceptual Entropy" (PE), and was defined decades ago. Once you exceed PE, you no longer have any hope of reproducing an audio signal that cannot be distinguished from the uncompressed original... You can only hope to make it sound acceptable, the distortions non-obvious, and eliminate sounds that might seem like they don't belong, anyhow. MPEG-1 Layer II audio, as used in DAB, is already quite close to that limit, and 128kbps compression substantially exceeds the PE for 44.1KHz stereo audio.

    For video, I will admit I have never heard of such a nice simple term and single study to exactly define the limit... Still, I'd be willing to make an educated guess that the figure is no more than 40:1, because (like PE with audio) a rather sharp tailing-off of improvements can be seen in subjective codec tests when nearing that level of compression, which spans the full range of codecs, no matter the technology used.

    As with audio, even early lossy video codecs (like MPEG-2) are sufficiently close to that fundamental limit to make the development of better high-bitrate codecs largely pointless. Instead, the focus has been, and continues to be, on the low-end, where you're simply trying to make it look "good", rather than identical, and can flexibly discard perceptual information in a way that it isn't too... distracting.

    There is still some room for debate on the subject, since MPEG-2 doesn't entirely hit the perceptual limits of lossy compression. Still, newer codecs don't have very much room to squeeze better compression out of video, while maintaining high-quality video that is close to being indistinguishable from the original.

    But if you want to argue that point with me, you face two further problems... First, I've used H.264/AVC encoders and recent/advanced MPEG-2 encoders plenty, so I can speak pretty conclusively when I say there's not much improvement to be had at high bitrates (but like HE-AACv2, it does an impressive job at very low bitrates). Secondly, I know codec internals pretty well, so I can also attest that H.264/AVC is heavily based on the same technologies as it's predecessors (MPEG-1, MPEG-2), and that all the (terribly CPU-hungry) improvements that have been made (eg. qpel vs half-pel, multiple ref/anchor frames, in-loop deblocking, et al.) simply can't provide very much compressibility improvement with high quality (weakly quantized) materials... The amount of change and randomness is too high for such tricks to be effective,

    that doesn't mean someone hasn't patented some part of the format at a later time than the standard came out,

    Yes, it does. You have 1 year after publication to file a patent. After that, any patent is invalid.

    Would such a patent pass the test of prior art? It depends on what they patented,

    It would be trivially easy to demonstrate the patent is invalid in the specific case of a MPEG-1 video encoder/decoder, since people were doing that before the (later) patent was filed.

    If the quality is a little bit worse, but it's still fit for the purpose, and it's free, then it has more value than superior technology that is not affordable.

    MPEG-1 is completely free, in most areas of the world, due to patent expiration.

    It'll also put Theora to shame in just about every respect. Encoding and decoding complexity is so low your digital watch could handle it, and h.264 offers practically no quality improvement at high bitrates, and only a small improvement at VERY LOW bitrates (what it was designed for).
