  1. Re:What makes Slashdot great on Computing for Near-Blind Children? · · Score: 4, Interesting

    Changing the DPI doesn't really make the image any more high resolution.

    I absolutely agree. However the issue in geography and geographic information systems often times is how many pixels represent the image. If you have enough pixels, there are operations that can be performed to enhance detail. Yes, your final image will be lossy in effect by resizing it and you will never be able to extract more information than is originally present (unless you have access to multispectral data), but it will be possible to more easily determine edges and relationships from one point to another.

    I am afraid you are an idiot befitting your Anonymous Coward title. Even with graphics that are not vector based, you can resize the pixel count in resolution and like I said in the original post If there is enough information in the original image to interpret, then one can bring up the contrast or otherwise enhance the image enough at a larger size to enable easier interpretation of relationship from point A to point B which would not be possible with fewer pixels.

    Take for instance edge enhancement filters..... Do you understand how image filters work? In order to enhance detail, one needs more pixels for the array to work on.

    This is part of what truly makes the Slashdot community great, and why I am proud to be a part of it. Geeks helping out others by poling a resource that has a truly flabbergasting diversity of combined knowledge. This question hits a bit close to home as my research is centered around vision and vision rescue strategies, but this is a more immediate need that I truly hope somebody here can help with.

    Just to clarify: I am not sure if you are asking for screen reader software or not as part of the solution? If so, there are a number of alternatives for Windows (fairly pricey), but the next version of OS X will have a built in screen reader solution! combined with other visual aids that will help the blind and near blind use their computer systems without having to invest in another solution.

    For the maps, there are a number of high resolution maps available from the USGS which can be obtained in digital form here and in atlas form here. In addition the CIA world factbook is a nice resource for kids with text and maps that can be remapped with higher resolution.

    Finally, a last resort would be Adobe Photoshop. You can take any map or image and simply resize the image with a much higher resolution (say take a map from 72dpi to 600 or 1200 dpi). If there is enough information in the original image to interpret, this might be a good solution to allowing one to zoom in images and maps for ease of interpretation.

  8. Superceded on Navy ELF to Be Scrapped · · Score: 5, Interesting

    Well, lets see: The VLF was designed to get around Soviet technology and communicate with our subs so the Soviets could not listen in on our coded transmissions. If VLF works (who else has an equivalent submarine fleet?) and ELF harms mammalian sea life, then scrap ELF. Besides, tuned wavelength lasers from space and aircraft can communicate (at least in shallower depths) with subs and not have to worry about spreading sound waves around the planet for all to hear and try to decode. Also, lasers can carry much more information than you can with ELF or VLF and you don't have to worry about carrier waves and such either.

    Also, having been on an earlier Australian sub (Oberon class), late model Australian submarine (Colins class), British submarine and several US subs, I might be tempted to say no other nation in the world can compete with the technology in the US subs. Everything else just buzzes through the water for all to hear while the latest Seawolf class is truly stunning with amazing amounts of technology layered upon layer that slips through the water with uncanny silence. Which brings up another issue: Why does the US need such a large submarine fleet? Perhaps to counter a possible naval conflict with China over Taiwan? I believe N. Korea has a few (ancient) subs...... More tactical boats perhaps would be prudent, but....

    This actually is a *BIG* thing. Built in distributed computing infrastructure that is easy to enable without a ton of scripting and custom coding has been a holy grail of distributed computing for a while. Programs like Pooch from Dean Dauger have helped considerably, but distributed computing built into applications that take advantage of an OS supported computing "grid" are another level entirely. Certainly folks that use film rendering and such can benefit, but so can users of Photoshop, not to mention a whole cadre of folks in scientific computing (like myself) for image analysis and clustering analysis (of images) and molecular simulations, particle based modeling etc...etc...etc...

  10. nothing new on Spysats Keeping Watch on the U.S. · · Score: 5, Interesting

    "Spysats" have always watched the U.S. starting with the very first Corona flights going on to the KH series from the 60's until the latest KH-12/13 Improved Crystal series. This is absolutely nothing new with organizations like the National Geospatial-Intelligence agency, that National Reconnaissance Office, the National Imaging and Mapping Agency and CIA having long standing contracts and plans to surveil regions within the boundaries of the U.S..

    When I was the subject of a recruiting effort in college for an un-named agency one of the things we discussed was merging of data modalities that would be far more powerful than capabilities then in place with the SR-71. These modalities were developed in urban areas within the U.S. such as Los Angeles and New York and a most public example was that one could see directly the collection of these data here in Salt Lake City at the last winter Olympics. Overflights of both aircraft and satellites to capture visual data, background radiation readings and other data were used in urban planning for placement of services, sniper teams, counter sniper teams and other responders. Teams were scouring this town taking images for overlay onto satellite data to build 3D models for all sorts of planning, so, yeah this is nothing new.

    What I am surprised at is how little folks know about the geospatial imaging community. It is a huge growth industry and the software that I currently use has been cobbled together from three different sources that most commonly runs on a variety of platforms from Solaris, to IRIX to Linux and Windows. I would love to see some of the code recompiled to run on OS X as some of the first code for geospatial imaging I ever saw ran on NeXTstep, not to mention that OS X is an ideal OS for this community. PCIGeomatics, ESRI, RSI etc..... are you listening?

  11. Level ONE! on "Levels" of Computers the Future? · · Score: 4, Insightful

    Well, by God I want a Level ONE computer. Is not that what all geeks will aspire to? On a serious note, this proposal is going to run into some problems with the definition and quantification of just what is "A computer". For instance, we are not far off from having multiple core CPUs on one chip which gives many software vendors massive headaches. Additionally, the concept of clustering (I favor xGrid myself) shows the problem as well. Are you defining a level designation per task? per installation? per "box"? Honestly this smacks of marketing speak that is designed to sell discrete "game" packages and I am inclined to dismiss it as such unless somebody can more clearly define why this is necessary or why this has applicability beyond the gaming market. I suppose that if you could "quantify" the nature of the task in terms of how much "horsepower" or throughput a given computer system is capable of then one could apply it to something other than a game. But the problem is often not CPU limited unless you are dealing with large calculations which occupy big iron many hours to days to weeks and even when working with games you have the problem of perception. One could establish I suppose a lower limit of 30fps on any given resolution and then that will dictate what level of hardware was needed to maintain that frame-rate, but even then there are going to be other issues.....shading......polygon counts.....ray tracing.....etc....etc....etc.....

    At any rate, because people should not let games wash over them like the TV does, they should have to work a little bit at it. Giving them options to tweak is important as it does teach some degree of problem solving and process optimization that for many kids at least is important.

  12. Why always somewhere else? on 3G Internet Access Via PCMCIA Card · · Score: 5, Interesting

    So the question is: Why is the US the last place that gets many of these technological advances in networking and wireless data access? When I was over in NZ a couple of weeks ago, there were little tiny cell phones from Japan that were unbelievable in their capabilities. Stuff that typically takes years to show up here in the States are being used by Japanese school kids as a matter of everyday life. A card such as this that connects to a 3G network and auto switches to GPRS where available! (yes, I did read the article) would be huge here in the US particularly given the diverse geography throughout the US as one travels from one place to another.

    Now if I could only get this either built into my Apple portables or get a 12in Powerbook or an as yet unreleased subnotebook with a PCMCIA slot....because the implementation and use of this particular card seems a little cluttered. You have to reboot with the card present in the PCMCIA slot which could be a Windows issue with networking I suppose.

  13. Resurgence of old on Digital Generation, Analog Retro Chic · · Score: 4, Interesting

    Certainly there has been a resurgence of old lately, but you will find this trend among any time where there has been a mass revolution in the way things are. For instance, the whole arts and crafts (Gustav Stickly, Morris, Green and Green, etc....etc...etc...) movement which in some part was a reaction or rebelling against the industrial movement of the early 19th century and celebrated the individual craftsman, designer and artist.

    Right now we certainly have a rebellion against the "digital world" in many senses with a resurgence of what is warm and old including the use of tubes in stereo equipment and musical instruments to growing popularity of "old phone styles", to automobile designs borrowed from older elements and Hollywood has been borrowing every theme and idea from movies in the past for many of its current releases in an effort to come up with something successful.

It was explained to me that this "new fangled CD technology" sounded too "crisp" and that playing the signal back through tubes warmed things up considerably.

    The cost of publication is not insignificant, and the issues related to electronic publishing are similar to those faced by all publication houses. However, the right business model will take advantage of this market and be able to compete with new practices where other companies are either unwilling or unable to succeed in. Many of the existing companies already have the means in place, just not the willingness to capitalize on this potential.

    Under the old model, when one would like to have their results published in journals like Journal of Comparative Neurology or Science or Nature, there are going to be publication costs, particularly if publishing lots of color images. Internet related journals like MolVis are significantly cheaper to publish in given that one is not making printing plates and such, but there are still labor costs associated with assembling the articles as most scientists know little about the nuts and bolts of publication.

    Publishing my last article in Journal of Comparative Neurology cost something like $4000 US due to the color images, and then there are costs associated with subscribing to those journals that universities and such have to incur. Again, moving to Internet related journals are significantly less expensive, but journals now have to worry about piracy issues as well as distribution issues and quality issues that for the most part the .pdf standard rectifies. Most of the journals are now publishing on the Internet with the .pdf standard, and now are dealing with issues related to how competition in the publishing business using the Internet.

    Now if we could only get a decent tablet design that allows for .pdf reading and markup.......Apple, are you listening? Do you want to leverage OS X, Quicktime, Preview, Inkwell, and the iTMS to gain entry into the publishing business? The academic markets would be ideal for just such an entry and could be a profitable cost center that for the most part has the standard (.pdf) but is missing 1) distribution model 2) appropriate hardware to deal with all of the e-book issues that as of yet have not had a decent solution.

    This is interesting. Right now I am traveling in Australia and New Zealand on business and the general impression I get here is that there has been a movement in America by the Republican party to take the country away from the people. There is lots of support for the American people, but very little for our government, and this is starting to cause problems with foreign companies wanting to work with US companies. Already we are having huge problems attracting foreign talent for projects in the US because of the visa restrictions that have been put in place and that is affecting more than just academia. It WILL trickle down into business and make the US less competitive.

    I would hope that the Democrats start looking into this and do more than their standard "launch an investigation", because I would suspect this problem is a little more intractable because of the fairly strong partisanship in the US right now.
