    You should know that the University of Utah has a long history of academic excellence in computer science. People like John Warnock (founder of Adobe), David Evans and Ivan Sutherland (founders of Evans and Sutherland), Robert Barton (principal architect of all Burroughs computers), Tom Stockham (created digital recording among many other things), Alan Kay (GUI guy at Xerox PARC, developed Smalltalk and is a fellow at Apple), Chuck Seitz (pioneer in asynchronous circuits), Ronald Resch (pioneer in computer art), Alan Ashton (founder of WordPerfect), Tony Hearn (developed the oldest algebraic math package, REDUCE), Duane Call (designer of the FPS-120 supercomputer and vector calculation specialist), Henri Gouraud (developed the Gouraud shading methods so important for all your games), Elliott Organick (Founder of SIGSCE and author of many FORTRAN and CS textbooks), Buit Tuong-Phong (invented the Phong shading method), Ed Catmull (computer animation pioneer and co founder of Pixar), Jim Clark (founder of Silicon Graphics, Netscape and Heatheon/WebMD), Henry Fuchs (founder of Pixel Planes and researchers in high performance graphics software), Martin Newell (object rendering and founder of Ashlar and co developed the Painter's algorithm for surface rendering), Frank Crow (famous for his anti-aliasing methods for edge smooting), Martin Griss (developed Portable Standard LISP), Suhas Patil (founder of CIRRUS Logic), James Blinn (Invented the first method for representing surface textures in graphical images. Scientist at JPL, where he worked on computer animation of the Voyager fly-bys), Jim Kajiya (Developed the frame buffer concept for storing and displaying single-raster images), Robert Johnson (Invented the magnetic ink printing technology used on virtually every check we write), Brian Barsky (Developed beta splines and methods to link computer graphics, geometric modeling, vision science, and optometry) and so on and so one are all graduates of our program.

    So, just in case some of our students read this (its always weird when your students say "I saw your comment on Slashdot yesterday"), I should have mentioned that there are exceptions to the rule (obviously) like the developers who are developing some of our image processing code right now here at the Univ. of Utah Scientific Computing Institute and our collaborators at the UCSB Center for Bio-Image Informatics. These folks are doing amazing things as is the neuroscience grad student in our lab who routinely amazes me with his ability to code. But these folks are in these graduate programs and environments because they are interested in solving innovative and new problems and they enjoy a challenge. The vast majority of students who are learning to code are not interested in asking questions or doing hard things. Interestingly, a large number of students it seems coming into CS programs at the undergraduate level want to program games, but have no idea how much math and algorithm development goes on when one is crafting new material. It's easy to use someone else's engine or physics models, but coming up with your own is harder and requires some talent and dedication to learning your craft.

  3. Kids today...... :-) on Why Johnny Can't Code · · Score: 4, Interesting

    I have been thinking it is due to a few reasons. First off, it seems that math education is sorely lacking in many college students. We are waaaay off the mark here with lots of remedial work being necessary for entering college students and this is having a major effect on peoples ability to develop algorithms. The next major reason is lack of communication skills and writing skills. When I was a grade school kid learning BASIC, we had it drilled into our heads that we had to comment our code and explain exactly what it is that we were planning. This was done to help us learn how to think through a problem, but also to get us to help communicate what it is that we were trying to do with our code. Finally, it seems that many students have gotten lazy and are simply looking for an easy way out and not wanting to code line by line.

  6. Stats on Top 10 Digital Cameras on Flickr · · Score: 4, Insightful

    Beautiful use of statistics and just the sort of thing that the Flickr board of directors can take to their marketing meetings. Companies eat this stuff up as it is a real world reflection of specific markets using their products.

    Interestingly, these statistics show that most of these cameras are solidly in the middle "pro-sumer" market and demonstrates that both Canon and Nikon did good when they went after a market that was primed to explode much like the 35mm market did in the late 70s and early 80s. Technology in both cases made it possible to build high quality cameras at affordable prices.

    Of course this means good things for the consumer, but watch out for a new megapixel war much like what we saw with computers and the Mhz war. Of course just like the Mhz war, the MP war is going to be mostly hype as I've seen some damn fine images from 6 or 8 MP cameras that were far above the quality produced by some higher MP count cameras. The secret is going to be the size and quality of the individual imagers on the CCD, the quality of the image management chips (I tend to prefer Canon's DIGIC) and the quality of the lens.

  12. Special sauce... on The IT Strategy That Makes Google Work · · Score: 5, Insightful

    One of the things that has consistently impressed me about Google is their willingness to look at old problems in new and innovative ways. Of course this is one of the hallmarks of a successful company, but it is not always successfully implemented. One example is their Google Earth application that made huge waves in certain agencies like NIMA. The interface made more than one NIMA/NRO/CIA analyst/project manager smack their forehead in stunned recognition of a superior way of layering and interacting with diverse types of data.

    The other thing that really impresses me about the company is the flat egalitarian structure that at the same time allows for tremendous independent freedom while also making much of the management fairly transparent which does tremendous things for morale. I also respect the encouragement of discourse including criticism. Not many companies can tolerate that sort of structure because they are built upon protectionism of management structures and establishment of castes of a sort. It shows that Google is one of the few companies like Apple that are succeeding because of their inherent talent. Google knows this and I would encourage them to resist the pressure to devolve into management structures that are having negative effects on tech companies as diverse as SGI, HP, Dell and Microsoft.

    As an aside, Google has shows a tremendously insightful ability to pick and choose product development talent at all levels over the years. I've been impressed by many of their hires. Whoever is heading up their HR dept. is talking actively with the Google special sauce R&D folks and they know their stuff.....

    The human eye has a "design" error, in that the photosensitive layer is not in front, there are other cells above them.......

    Actually, the mammalian (human) eye is optimized for the metabolic loads it requires. It turns out that there is no higher area of metabolism in your body than there is at the photoreceptor/retinal pigment epithelium interface. It is a highly oxidative environment and evolutionarily, you need the apposition of the photoreceptors up against a layer of cells that can deal with the shed outer segments and the metabolic loads induced by rod photoreceptors. The other advantage is that you can snuggle the photoreceptors up to these cells that have a direct connection (diffusion) to a vascular layer. If it were backwards, the blood vessels would get in the way of the image formation and cast shadows.

    In mollusks, OTOH, the outer layer of cells is the photosensitive one. The eye is more sensitive to light, has no blind spot, and allows for more data processing in the retina itself. That may be one of the reasons why octopuses are so good at camouflage, their eyes are very sensitive.

    Octopuses, squid, and cuttlefish have fairly sophisticated retinas that is true and you are correct about their anatomy. However, they do not process the same metabolic loads that the mammalian retina does and thus do not require the same degree of buffering, care and feeding that mammalian photoreceptors do. You have to be careful about using "sensitive" to describe eyes as that descriptive is dependent upon lots of things. Typically in most retinas it has to do with the ability of the opsin to capture a photon and the cell the opsin is in to transduce that signal.

    All this is one more argument for evolution and against the "intelligent design" theory.

    Intelligent design (ID) really does not even factor into either argument. ID is a religiously/politically motivated belief, not a theory that can be tested.

    The number of genes is not necessarily an indicator of sophistication. Also I should point out that as you allude to in your sarcasm, we humans are not the most sophisticated at all biological functions. For instance, the human eye is a much less sophisticated device than the eyes of other creatures such as birds, turtles and even many fish species who see in many more "channels" than we do with greater color discrimination (and they can often fix their retinas when damaged unlike us who suffer when AMD or retinal degenerative diseases hit us).
