  1. Re:Incredible chip! on Motorola G5 - 2Ghz 64bit · · Score: 1

    You can use a computer you already have as a general-purpose DSP without using a DSP chip as the CPU. However, you're not going to get as good of performance (read: You get what you pay for). And the majority of DSP chips are not compiler friendly (although this is changing in some of the newer generation chips) because DSP chips have structures that are difficult to map into HLL's like C. Putting a general purpose OS on a DSP chip will only end up hurting performance. If you want a quick prototyping base for DSP work, use your computer. If you want peak price-performance, you're going to do it on a DSP chip and with a minimal RTOS.

    Now last I looked, TI's 'C6x architecture was headed that way with speed and scalability, but no one is ever going to write or port a general purpose OS (ie, Linux, Windoze, MacOS, Be) for/to that chip.

    Uh, why would you port a general purpose OS to a DSP chip? DSP chips are special purpose devices that fit a lot of niches (well, okay, niche really isn't the word since they outsell CPUs by orders of magnitude) that don't need general purpose processors. Much better to have a controller chip of some kind (say x86 or PPC) interfacing with a DSP farm for processing.

    That choice is probably out of their hands. More likely, the decision to place the bulk of the process of determining merit on the courts was enacted by some higher up, perhaps in Congress or the White House. And those people are most heavily influenced by the major corporations, who realize that court time is expensive, and likely will rely on the decision of a non-technical person or group of people to make final decision.

    Is there anyone out there besides me who realizes that a lot of the questionable patents could be weeded out if the patent office wasn't badly understaffed and undertrained and if they weren't under pressure by Congress to handle applications faster?

    A little reality check here: the number of people working as patent clerks who have a strong background in high tech fields is probably very small. These people don't get paid the kind of money that can be made in the industry. And they're under a lot of pressure to get applications processed as soon as possible. How many of you would honestly be willing to take a job with the Patent Office? If it meant you could do something concrete to regulate what gets patented and what doesn't? Or what about lobbying to get more and better trained people working at the patent office and give them more time and resources to research patent applications? There's too much money invested in the system to expect it to just go away, but that doesn't mean the system can't be used properly.

    Hmm...need to carefully read article when brain isn't so foggy. Economics == Nap Time.

    However, a quick read of the introduction suggests that differential pricing isn't such a bad thing in some markets:

    The outcome of this investigation is that

    (i) efficient pricing in such environments will typically involve prices that differ across consumers and type of service;

    (ii) producers will want to engage in product and service differentiation in order for this differential pricing to be feasible; and,

    (iii) differential pricing will arise naturally as a result of profit seeking by firms. It follows that differential pricing can generally be expected to contribute to economic efficiency [2].


    Admittedly, I am kinda tired, and could easily overlook something. If production costs are separate from shipping and placement costs, then it's easy to see the hardcover costing more, or at least having slimmer margins. I guess the biggest thing is to look at all the different places that the price difference can come from:
    • Production Cost Differences
    • Shipping Cost Differences
    • Placement Cost Differences
    • Bookstore economics (shelf space, quantity, etc.)
    • Basic Supply vs. Demand
    • Others that I'm likely overlooking
    The only way to really know where the price difference comes from is by tracking the price per unit from tree to consumer.

    Perhaps a better way to do this is to have an online resource (say www.ora.com/student) that provides the practice problems and answers. Too often I've found textbooks where the answers are wrong. Having the problems online makes it easier to fix errors. Also, other people can submit problems, so the author isn't burdened with additional content to create. Having a high quality reference is a good thing. But too many people might think that a new edition of a book contains more than just new problem sets. It's better to keep the reference and the teaching parts separate. Alternative solution: Separate, low cost problem set manual.

  8. Re:Hardcover vs. Softcover on Interview: Tim O'Reilly Answers · · Score: 1

    I've heard that the hardcover and softcover versions of a book cost about the same to produce, and that the purpose of a hardcover edition is to extract extra money from people willing to pay more to read a book earlier (since the hardcover comes out well in advance of the softcover).

    I'd like to see this validated or debunked. My gut feeling is that it's wrong. Hardcover books are almost universally heavier and bulkier than softcover versions with the same content. For equal numbers of copies of each, the hardcover version will end up with higher material costs (okay, the fancy ORA binding might make up for this) in production, and higher shipping costs, due to the higher shipping weight and volume. Factor in the economies of scale that result from differing volumes, and the price spread can swell.

    Of course, issues such as font and page size play into this too, but who wants a hardcover book that requires a magnifying glass to read?

    Actually font aliasing blurs the font out, most often making it harder, not easier, to read (IMHO). It's helpful for lines, curves, etc. but definitely not for fonts. Unless you don't value your eyesight that is.

    Antialiasing doesn't sharpen anything. How can it? It's blurring it to make it smoother. And it's not a really trick of the human eye either. I've yet to see a computer graphics book that properly discusses the reasons for antialiasing. But a lot of that is because many CS types don't have a good background in Fourier analysis. The human eye, much like a monitor, is a point-sampling device. However, the human eye has much higher resolution than any monitor can hope to achieve. As a result, the lower sampling frequency of the monitor is visible as the so-called "jaggies" (high frequency transitions). Anti-aliasing attempts to reduce the impact of the jaggies by interpolating pixels to produce smoother (lower frequency) transitions graphically.

    I'm not sure I'm all that interested in writing anything major for the public domain, since the GPL allows just as much use of the software, but also encourages other people to produce Free software.

    This isn't meant as flamebait, but I've got a couple of problems with this (although they're closely intertwined):
    1. The GPL doesn't allow just as much use of code as true Public domain code. That's because the GPL restricts how any code covered by it is used.
    2. "Encourages other people to produce Free software" puts it lightly. Obligates law-abiding users of GPL'd code is more like it. Public domain code has no restriction on how it's used in a software project. GPL'd code does.
    Anyways, those are minor semantic issues.

    I think your post gets at the heart of any economic system in that there's always going to be problems that aren't easy to resolve. How would something like the Linux kernel or the GIMP be handled under such a system? There you have a open development system where many people contribute differing amounts. Figure that out and you can better handle "bazaar"-style development projects under this system.

    As to your scenarios:
    • Scenario 1: Some would say that the author should undertake the project anyways, for the academic gains achieved. But in reality, if he undertakes the project anyways, he may lose money, in addition to valuable time he could've spend working on other interesting projects.
    • Scenario 2: That's a problem of an inflexible contract. There should be elements of the contract to account for overruns in development time, in addition to incentives for faster development.
    • Scenario 3: Good luck solving that one. Perhaps partial refunds if the developer and contractor agree it's not worth pursuing. But you won't find an easy solution that makes everyone happy.
    Economic systems are not simple. There's many complex situations that can arise that need to be thought out. And there needs to be a way to retrofit the system with additional tweaks to handle situations that weren't envisioned originally.

    FWIW: At a place I used to work at, they were considering a very large CD changer system (~60+ IIRC). After looking into it in greater detail, they decided instead to buy a bunch of HDDs instead and copy the CDs onto the HDDs. If you use SCSI HDDs, then multiple people can access multiple files/disks at the same time, and the overall cost (for them anyways) actually worked out cheaper. I suspect that at the prices you quoted, you wont be able to access multiple CDs simultaneously. Disk will be more expensive for you, but probably a better all-around solution.
