  1. Re:My prediction on Microsoft Codec Required For Blu-Ray Players · · Score: 1
    My prediction is this, someone will reverse engineer the codec and release it a la DeCSS and everyone will have it. Microsoft will try to shut it down and there will be T shirts with the code printed on them.

    The difference this time is that the intellectual property is protected by patent rather than by copyright (the DMCA). You can't legally reverse-engineer a patented device -- and shouldn't have to, the patent has to reveal all the secret stuff. You can't legally use a patented device without the permission of the patent holder -- there's nothing like "fair use" in the patent area. Heck, you can't legally own a patented device without the permission of the patent holder -- a patent is an absolute, government-enforced, temporary monopoly on all uses of your invention. When people go to jail (or more likely, pay very large financial penalties) for printing up the T-shirts, it will stop in a hurry.

    Among other reasons, this is why I am strongly opposed to the very notion that algorithms (like a video codec) should be patentable.

    Isn't that the same argument the established telecos are using to "encourage" state governments to tax VOIP?

    To some extent, they have a point. So long as VOIP is people using their computers and the Internet to talk to each other, I agree with what I think you're saying, and taxes are not appropriate. Once the VOIP providers start saying "We want numbers out of the North American numbering plan (or its equivalent elsewhere in the world)" and "We want to interconnect with the public phone networks" it becomes a different issue. Now they are providing telephone service, which is much more than just transport and all the existing players in that space are regulated and taxed. I can understand the telcos complaining if the new entrants are held to different standards than the existing providers and given tax breaks too.

    Personally, I would be more interested in seeing whether or not the VOIP providers could meet the very tough reliability/availability standards that the local wireline companies are held to. Residential phone service could be substantially cheaper if it was not held to "four 9s" availability levels by state regulation.

  5. Re:Alternative view on Time to Kill Microsoft Word? · · Score: 2, Interesting
    The gyst is that Word, and all word-processors, confuse the distinct tasks of preparing your text logically, and laying it out. This leads to the standard situation that frustrates me when I have to use Word: I am entering text, when I see that it won't fit on a page, so I stop thinking about my text to change paragraph formatting and then, oh, where was I? Later I'll change the text, and probably want to change the paragraph formatting back, but won't be able to remember what it was before. Now my document is inconsistently laid out.

    Many years ago, Bell Labs commissioned an internal study comparing WYSIWYG text preparation tools versus troff (with a decent macro package). The content used in the test was large-product internal documentation, documents running hundreds of pages and prepared by teams. Test subjects using troff were about 20% more efficient, and the troff version of the "finished" documents contained far fewer style "errors". This was not the result that the department head wanted, so the study was repeated with different people and different documents, but the results came out the same. Human factors experts involved in the study identified exactly what you've suggested as the cause of the inefficiency -- people worried about page layout and text styles far too early in the process, wasting their time making text that was almost certainly going to be replaced or at least changed look good. Just to be fair, WYSIWYG editors for drawings beat pic hands down.

    My own complaint about Word, having used it off and on for 15 years, is that it still can't do floating displays, which tools like troff and LaTeX handle easily. Every technical paper or book chapter I've ever written has such displays. Which has been true of academic-style material for a very long time. Almost 50 years ago my father helped work his way through college doing typesetting at the university print shop. He heard me bitching one time when I was having to use Word about its inability to do floating displays, and knew immediately what I was talking about.

    Oddly enough, Comcast has a Linux-based program named NETSIM that does exactly what the original article was looking for. It emulates queueing delays for a variety of access technologies (dial-up, DSL, etc) including custom settings. It emulates network impairments like delay, jitter and loss. It has been used to test a variety of commercial IP-based services under a broad range of impairment conditions. The usability group made extensive use of NETSIM while evaluating different upstream/downstream speed limits for possible tiered service. It has the useful attribute that it runs entirely in user space, although it does need root privileges. It ran on every version of Linux that I ever tried it on. There's a nice Tcl/Tk control interface that works well for certain kinds of demonstrations.

    I know they have it because I wrote it and conducted many of the studies while I was at USWest Advanced Technologies. Ownership transferred to MediaOne Labs when USWest split itself in two. At that time, we licensed it to a variety of other groups under the best terms I could get out of our big-company lawyers: use for whatever you want internally, modify as desired, but no redistribution. There's a patent for it, one that's quite broad and that dummynet probably infringes. MediaOne didn't care, the patent was applied for so that no one else could get one and force us to stop using our own program. For those who care about prior art arguments, TTBOMK NETSIM predates both dummynet and NIST's nistnet software. When AT&T bought MediaOne, the Labs survived but in reduced form. Licensing of NETSIM stopped, although we continued to use it internally. When Comcast bought AT&T Broadband, most of the staff at the Labs were laid off. I turned over the complete documentation, source code, and an operating NETSIM installation on my way out the door. However, I would be surprised if any of that made the trip from Denver to Philadelphia, so in all probability, the program is no longer available.

Routine homework for primary education is one of the LAST places immersive VR will be used.

    As to the nuclear family itself, in the 2000 census, married couples with children under 18 made up only 23.5% of households in the US. Given the known historical trends, this will fall to 20% or below by 2010 -- that is, in 2014 such a household will be rather atypical. In 50 years, the typical household will be an unmarried couple, average age 50, only one of whom ever had any children, and those children are grown and gone. The technology in common use at that time will be driven by that sort of household. A futurist piece describing technology in 2054 using the married-with-children family as an example is almost guaranteed to be seriously wrong because those households will be so uncommon.

Western Europe and Japan are roughly the baseline for efficiency -- their per-capita GDP is about the same as the US, but they use about half as much energy. Western Europe and Japan have some clear geographic advantages compared to the US and Canada that makes it easier for them to be more energy-efficient. Hong Kong is pretty much at the extreme of efficiency for a rich "country", using only about one-quarter the per-capita energy of the US. But we can't all be Hong Kong -- someone has to grow crops and refine metals and all the other energy-intense activities a developed economy requires.

    At least four billion people on this planet live in poverty -- very low per-capita GDP. For the economies in which they live to become richer, they will have to consume more energy. For example, look at the increases in energy consumption in China over the last ten or fifteen years as their economy has boomed. Energy consumption is not up because they got richer -- they got richer because they increased their energy consumption (and hence the goods and services produced per person). We produce enough energy worldwide ONLY if you're willing to tell those people that they and their children will have to be poor forever.

Someone asked where US imports came from currently -- I had looked it up for other reasons recently and could give some numbers.

    The larger reason to be interested in oil in general is that most economists greatly underestimate how dependent the developed countries' wealth is on the availability of energy. When they talk about factors of production, they list labor and capital and a few others, but they don't typically list energy. And yet, people in those countries are as productive as they are (which makes their countries rich) because they apply huge amounts of energy to the production processes. And there's no substitute for energy. You can't switch to different raw materials and get away from the energy requirements. You can't substitute more people for it and still maintain the output per person. You can't have extreme specialization and large economies of scale unless you have the necessary energy for transport.

    You can put together a case that argues that within a few years, global oil production will reach an absolute peak and begin to decline. A similar argument can be made that global production of natural gas will peak within 20 years. Conservation will only take you so far. How will the enormous energy demands of the developed countries be met in 20 years?
