Recomputing the Sky 205

An anonymous reader writes "Microsoft has unveiled the largest and clearest image of the night sky ever assembled. This so-called 'TeraPixel' sky map was generated with the help of some of Microsoft's latest HPC and parallel software assets. Quoting: 'Compared to the old sky image, the TeraPixel version is much more refined. With all the artifacts, seams and inconsistencies processed away, it looks like a true unified image of the sky above. It's like going from Super Mario Brothers on 1985-era Nintendo consoles to Halo 2 on Xbox 360s.'" You can view the image at Microsoft's WorldWide Telescope site — it requires the Silverlight plugin for Windows or Mac. No word at the site about Linux or whether Moonlight works there.

    Oh, I see what you did there. Here, let me try:

    It's like going from gaming on Windows 1.0 in 1985 to 1985-era Nintendo consoles

    Or what about

    It's like going from a red ring of death on an XBox console to Gran Turismo 3 on a Playstation 2

    Oh and I also enjoy that you used your Space Act Agreement with NASA to "make planetary images and data available via the Internet to the public" and also promote the download and installation of silvercrap. Can't do something for the public without advertising and pushing proprietary software on people, can we? I hope Google gets the chance to do this with HTML5.

    So this looks like a really cool thing that MS did, so I'm going to wait in wide eyed anticipation at how the slashdot community is going to trash it because it's from Microsoft and not Google (or at least be more overly critical of it). I do hope I'm wrong though.

      They should have done it with JavaScript and JPEGs instead of using Silverlight, which doesn't work on my Linux.

      Good enough as first bashing? .-)

      • You at least give a viable reason for disliking Silverlight. Most of the commenters just seem to hate it because it's Silverlight. Why they don't make a Linux version of it is beyond me, they really ought to.

        Now to play devil's advocate: I don't see why Silverlight garners so much more hate than Flash around here. Both are pushed using the same tactics and neither is really open. Flash has just been around longer.

        • I have to say, I dislike them both equally. Flash because it has been around too long. Silverlight because it is really just flash again when the entire idea should have been replaced.

        Playing devil's advocate -- it's pretty trivial to make a Silverlight interface to pan and zoom around a giant image like this. It's less trivial to do the same thing with, say, JavaScript or Flash.

        This is one of the handful of things that Silverlight does really well.

        Because of that, I wouldn't be surprised if this project was less a "We've got this cool thing, what Microsoft technology can we push with it?" and more "What's a thing we could do that would really show off a strength of Silverlight?"

          I'm just not sure it's true. ImageScope provides a workable flash interface to allow you to view 10,000 MPixel images just fine. It's not all that hard whatever you're writing it in. Pyramid tiled images make writing a front end pretty easy to be honest. I think the good work they've done is the image processing at the back end to get this data into nice shape in the first place.

          Actually you're trolling more than playing devil's advocate. There's a sh*tload of zoom & pan-enabled image viewing libraries, both in JS and Flash, all using tiles just like Silverlight -- try to google some.

          And for that matter it's trivial to DIY from scratch using canvas, which of course IE conveniently doesn't support, but that problem was solved too long ago. OpenLayers [openlayers.org], which you might have seen at work at OpenStreetMap [openstreetmap.org], includes a VML rendering backend, besides canvas and SVG.

          The really funny part about your "advocating" is that MS has an Ajax library that does exactly the same thing as its Silverlight counterpart: http://www.seadragon.com/developer/ajax/ [seadragon.com]

        Except that Silverlight is probably _why_ they did it in the first place. Flash and standardized HTML5 are threats to Windows and without Windows Microsoft is history so Silverlight is the hammer, the night sky is but one nail. Is there an iPhone or Android app for that? I didn't think so but you can bet that when they ship the next new Microsoft phone software, they'll release one for it.

        20 years of watching these people operate points me to these kinds of conclusions.
