  1. Good writers are good readers on Teaching Engineers to Write? · · Score: 1

    Hopefully someone else has made this point already:

    If you want your students to write well, you must do things to get them to read well. For engineers, this means having them read several technical reports, business memos, product specifications, etc. It is very much a "learn by example" situation.

    Oh come on, the idea of using Rip-Maps have been around for *ages*

    I'm sure they have. I'm simply saying the patent in question appears (in light of scant information from the party doing the suing) to apply to a particular dusty corner of the jpeg standard, one probably not used in mainstream implementations. I have no idea whether it's actually a valid patent or not (other than having the general opinion that most patents are bunk).

    Sounds like progressive JPEG to me, in which case the patent would apply to browsers.

    Perhaps. Though progressive, as I understand it, isn't really a diff of images. It's one image where, at each stage of refinement, more data is displayed. Ie, it's simply a way of displaying a subset of the pixel information on-the-fly. See What is progressive JPEG?

  5. Shouldn't affect commodity JPEG on 31 Lawsuits Filed Over Alleged JPEG Patent · · Score: 5, Informative

    After perusing the comp.compression faq for an overview of jpeg (see question [75]), I don't think this patent, even if valid, will affect JPEG as we know it. As the parent post points out, the patent covers compression via diff's between images. (This is, as I understand it, a major component of MPEG encoding, so I'm curious why they're not the ones getting sued.) JPEG, as your web browser uses it, likely doesn't use such a technique. From the FAQ:

    The hierarchical mode represents an image at multiple resolutions. For example, one could provide 512x512, 1024x1024, and 2048x2048 versions of the image. The higher-resolution images are coded as differences from the next smaller image, and thus require many fewer bits than they would if stored independently. (However, the total number of bits will be greater than that needed to store just the highest-resolution frame in baseline form.) The individual frames in a hierarchical sequence can be coded progressively if desired. Hierarchical mode is not widely supported at present.

    My take is that this "hierarchical mode" extension is the part covered by the patent. The problem is that, assuming the FAQ article is correct, most implementations of JPEG decoding we encounter won't support it, meaning most people aren't going to be encoding their JPEG's this way since it would be incompatible with mass-market JPEG implementations. It sounds more like something a company would use as part of a proprietary format built on JPEG.

    Bottom line: don't expect this to have any ramifications for Mozilla, IE, etc.

  6. Breaker, breaker... on Your Most Damage-Resistant Hardware? · · Score: 1

    Had a 14" monitor where the "push-on, push-off" power button had become stuck in the off position. Opened the case, tried to get it unstuck, no dice. So I decided to wire around it and use the power strip it plugged into as my on/off switch (I was going to buy a new system soon anyway). Naturally, I wired it wrong. When I turned it on, POP went the monitor, and trip went the breaker. Opened it back up, re-wired it (correctly this time) and it worked fine ever after.

  7. warping you brain on What About Functional Languages? · · Score: 1
    is what functional programming does. and i like it. it's the most fun way to program in existence.

    part of the reason we don't use it is that programming is taught as a means to an end (ie, to write programs) which implies C/C++/Java. not that this is necessarily bad -- it's where the $$ is, after all. if academic institutions were more concerned with the mathematics/theories behind computational machines, most likely they'd use functional languages more (it's my understanding that MIT does this). but about all you can use it for, in the real world, is writing emacs extensions. :)

    the sad part, though, is that, in small doses, fp's can be quite useful in real-world apps. they certainly are powerful when dealing with complex data structures (imagine doing in 5 lines of Lisp or SML what it'd take 50 lines to do in C). it'd be nice if API's existed for C/C++/Java that could take in-lined fp code and integrate it with the larger program, when such would be useful. and maybe those API's are out there already.

  8. Problem as I see it... on Are Computers in Classrooms Bad for Learning · · Score: 1
    Is, first of all, schools are spending big bucks to throw computers at kids so they'll have "21st century classrooms." And, most of the time, have no real clue what to do with them. This same money could be spent increasing teacher salaries (thus attracting better teachers to the field, thus raising teaching standards, thus turning out better students, and on and on...) But instead we have mediocre teachers who know nothing about computers teaching rooms full of kids and pc's (both of which will be obsolete in 5 years...)

    A decent book on the subject is (AI researcher) Roger Schenk's Cognitive Computer. He makes a case that the only useful thing a computer has in education is learning problem-solving techniques via programming. You don't need a pc for every child to do that. An hour or two a week in the computer lab is plenty for gradeschoolers. Maybe offer a daily class in high school. But as far as the bulk of education goes, the old-fashioned ways involving books, essays, and pencil-and-paper math are just as good today as they were 100 years ago. Don't bow to corporate america's warnings that our kids "aren't ready for the workplace of tommorrow." They're 10-year olds, for heaven's sake.

    In a sense, you paid for a service that they were restricting without giving you the option of saying "no thanks".

    Perhaps. Using my school as an example, where labs were walk-in (after learning that checking id's was mostly useless), it would be difficult to keep those who had not paid their access fee out of the labs. Not that many students could get by without it, anyway. Classwork usually demanded internet access to some degree. And don't even start talking about metering internet use per person (like a phone line). Whether you were informed or not (and all policies concerning internet use in schools should be available for perusal), it's a moot point. You need access for academic work, and that's what you're paying for. Opt out doesn't happen, unless you can find a school that doesn't have internet these days (good luck.)

    not exactly sure what you mean by 2.5d layout... but some people in my lab are working on a design that involves layering processors one on top of the other, and using optical interconnects (instead of wire) to pass information int the z-direction.

    anyhow, something I've not heard mentioned, but that is extremely important when dealing with wires this size is the propagation delay through the wires. under current technology, transistor speeds have already outstripped wire speeds (ie, how fast an electron can move along a wire). as wires decrease in diameter, they get slower (more resistance). definitely will be a problem if they're planning on using this technology to simply miniaturize existing hardware styles.

    Hmmm... I'm been all for bug liability falling to developers for some time now (ie, the death of shrink-wrap). I hadn't considered its implications for non-commercial (OSS, etc) programmers. I suppose one route is to keep shrink-wrap, but tweek the GPL so that it becomes binding to anyone who *uses* the software (otherwise, the warranty disclaimer in sections 11 and 12 won't have any teeth). I'd hate to have to do that, though. Would it be possible to remove liability in the case of software distributed free-of-charge? Ie, the commercial developers are responsible for their product, but if you get something for free, you're on your own?
