He covers a lot of ground on XML and the next generation of GUI. It connects a lot of technologies that people might otherwise not totally grasp. If you haven't been following the development of XForms, E4X, SVG and XAML then this is a great way to catch up."

        It's a bit more than that. There is support for interactivity. There is support for pulling in content over HTTP. For example, the SVGs generated by GPS Visualizer [gpsvisualizer.com] pull in maps layers from various bitmap sources, allow you to drag labels around and adjust the opacity of layers using a slider.

        Also, Javascript can access SVG DOM. Imagine Google Maps implemented on that kind of technology.

      What is this new technology

      SVG? New? Not that is news! SVG 1.1 was ratified on the 14th of January, 2003. Most SVG users either view the files in the Adobe Plugin [adobe.com], or translate to raster images [apache.org] for vector charting and the like. (I actually had a pretty cool 3D pie chart program for awhile there. SVG came out of one end, translated by Batik, then viewed as a PNG.)

      why should I care about it

      You shouldn't. It's just technology marching on. If you need to do vector graphics, you'll find it far more up-to-date and better supported than PostScript. If you don't need to do Vector graphics (or don't even know what vector graphics ARE) then you definitely don't care.

      As a computer expert of 20 years and programmer of 15 years, how will this effect me?

      You'll need a new bullet-point on your resume in a few years?

      Will I have to learn totally new things, or does it build on the old ones?

      You know XML? You know PostScript? How about ECMAScript? Yes? You're good to go then.

      Who owns the patents to this new technology?

      It's older than the hills technology. I dunno, maybe my great grandmother had a patent at some point, but there are none now. (Unless someone invents a stupid one like "Method for storing Vector graphics in XML." Hmm... maybe it is patented.)

      Will Microsoft release their own version of it and crush everyone?

      Microsoft Internet Explorer (Exploder in my book) needs the Adobe plugin. AFAIK, Microsoft is mostly ignoring it.

        Well you clearly haven't come across the beta for Acrylic - http://www.microsoft.com/products/expression/ [microsoft.com] - which merges vector graphics (SVG, yee-haw) and raster.

      SVG [wikipedia.org] or "Scalable Vector Graphics" is a way of describing visual information (graphics is perhaps misleading, as it can include text) in a way that is independant of parameters like dimensions of your display, type of display device, etc.

      Some advantages of SVG:
      • For the Web, the browser gets to decide how to render graphical information (so for example, client-side anti-aliasing preferences can be used).

    Even if it is somewhat slow and clunky, at least it shows that it is possible to do.

    At this point, it is such a monumental task to implement all the intricacies of the full SVG specs that *nobody* - Not Microsoft,Adobe,Apache, Sun,Apple of anyone in the open source arena is able to do it, or even come close, it seems.

    Apps like Inkscape are probably the most advanced SVG showcases, but for some reason everybody wants to write their own browser plugin from scratch instead of starting from the authoring tools and extending them to support a 'playback' mode.

    Has nobody noticed Flash and what made it so popular?

    You can publish standards till the cows come home but the only way anything becomes popular is by being useful.

    A reference implementation of a standard is immediately useful, both to users and to developers. Why isn't it there, and if the answer is 'it's too much work' then maybe, just maybe, the overcomplexity of the standard is the problem.

    Standards are a good thing, but standards must be both implementable, and accompanied by an implementation, unless they want to float in limbo for years like SVG.

      • The other approach is to first let the world sort out what features are actually desirable, then standardize what's there and try to get implementers to converge towards the standard... Common Lisp is an example of this from programming languages.

        Don't, don't, don't follow Common LISP as an example. Common LISP has been a disaster. There are far fewer people earning their living from LISP now than there were before Common LISP standard was introduced, and far fewer programs in regular use written in LISP.

        Common LISP is a very bad standard. As Scott Fahlman [cmu.edu] wrote [google.com]:

        The result is a language that... not even its mother could love. Like the camel, Common Lisp is a horse designed by committee. Camels do have their uses.

        He should know. As he says on his home page [cmu.edu]:

        I was one of the principal designers of the Common Lisp language.

        Common LISP essentially destroyed LISP as a usable, productive language. It made an incredible number of simply wrong technical decisions; and too many of those decisions were made by the smaller companies of the eastern United States - Symbolics, LMI, Franz - trying to write a standard which was as different as possible from InterLISP [wikipedia.org], in order to kill competition from Xerox. I'm not pretending InterLISP was brilliant or the answer to all problems. It wasn't. Like Common LISP, it was a LISP2, making an artificial distinction between data and code; and it was in many ways clumsy and unorthogonal itself. But there was a great deal of creativity coming out of the InterLISP community, which Common LISP effectively killed.

        We would have been so much better with a standard based on Portable Standard Lisp [metu.edu.tr], or on EuLisp [bath.ac.uk], or on Scheme [mit.edu]. We would have been so much better with no standard at all. Instead, we got a LISP2 with a bizarrely complex lambda-list syntax, with a comment syntax which was incompatible with the LISP reader (so that in-core editing and development were effectively impossible), with so many horrible design errors.

        Of course, it succeeded in its primary goal. Xerox was driven out of the LISP marketplace. But the cost for LISP has been horrendous: the language has been effectively destroyed. And for what was and should be the queen of programing languages, that's a disaster.

        Oh, yes - I was during the eighties a very junior member of the British Standards Institution's LISP working group. I was there. I still think LISP is the best possible programming language, but these days I use Java.

        This is a very different story. CSS had to compete with unstructured HTML code full of font and color tags, and it was clearly a technically better solution (although complex). Everybody is using CSS because it is the only way to separate the content of a web page, from its presentation. And because CSS is extremely popular CSS2 has a clear road ahead.

          This is a very similar story. SVG has to compete with semantically void images, and it was clearly a technically better solution (although complex if written by hand). Everybody will be using SVG because it is the only way to separate the content of images from their presentation, and to make them properly scalable.

          The situation of CSS was very similar. (Presentational) HTML was already a very mature platform which did almost everything that CSS does now years ago and it did this in a very coh

          • If SVG was released when CSS was (i.e. ten years ago), maybe your argument would have made sense. You say that "SVG is the only way to separate the content of images from their presentation, and to make them properly scalable" and you are wrong. Flash has allowed this for many years now. No, it is not a standard, but it seems that nobody other than you and me cares about it. And, well ... why should they?
            • Have you ever tried viewing the source of a Flash file? That should give an indication of how easy it is to use a piece of it inside another file, or how easy a screen reader or non-textual browser would display the contents. SVG with XHTML embedded can easily be stripped down to just the contents.

  • The OpenSVG talks are being streamed live over the MBONE. How come the MBONE is still experimental? How come it hasn't been replaced by a standard tech in all routers? Does IPv6 do multicast? The version being rolled out in some routers today?
    • The Internet does not support multicast, because multicast requires routers to carry lots of routing table entries, and those aren't free. So far I haven't seen any good solutions to this problem.
    • IPv6 does do multicast. The mutlicast join protocol is different (MLDv2, as opposed to IGMPv3) and you get a few trillion addresses (multicast gets a 120-bit range of addresses) but otherwise it is the same.

      The MBONE was technically disbanded a decade ago - the Internet backbone has been carrying native multicast (as opposed to tunnels) for a long time. It is ISPs that are the problem, refusing to enable it.

      Virtually all modern routers support multicasting - IGMPv2 and DVMRP at the very least, with more mod

Other big ISPs, including DSL/telcos, are in the same position. Why do you think they haven't already jumped on this? Wouldn't they also be trumping their independent ISP competition (such as it is, like Earthlink and some mom & pops) with their superior service?

        • It would be infinitely cheaper, easier and more reliable. (Fewer streams = fewer packets dropped = more bandwidth usable = more channels + higher quality MPEGs) I have absolutely zero idea on why they've not jumped on this - UUnet/MCI is the only big ISP I know of that supplies multicast to the home, the others I've asked simply say "we don't do that" and decline to say why.

          It would certainly multiply the value of their content. It would also multiply the value of their service, as it would reduce the start

          • The only "good" reason I can think of is that they're afraid of multiplying the downloaders, and therefore losing more of their content to piracy. It's idiotic, but the copyright owners have relied on bandwidth being too scarce to "email movies" among friends, rather than take any constructive action. It's one reason why they've let the RIAA fight it out over such small potatoes as the piracy share of a merely $14B:y industry: they want to study the "lab" before doing anything, and bandwidth scarcity buys t

    What is so cool about SVG is talked about in this keynote. SVG, is vector graphics AND text, AND placed raster images, AND animation described in an open, easy to read format.

    One advantage is that you can design a webpage the same way you design a printed piece. Where you have just as much control over it. MS explorer requires an adobe plugin to display it, similarly to how it displays flash. Firefox is going to display SVG natively in the 1.1 browser (actually already does with the deerpark alphas.

    The code is easily visible like HTML. The desktops that use SVG for the gui, I don't know much about, but it's fantastic. Nice icons, or buttons or any visual element that is smaller in file size, breaks out of the square we are used to, and the elements can be enlarged or reduced and still be rendered beautifully.

    check out inkscape if you want to experiment with svg, or the open clipart library to see some cool examples. of SVG.
