  1. Re:Direct link to the images. on Images of Endeavour's Damaged Tiles · · Score: 2, Interesting
    That's absolutely correct. It's not thermal. If you look at the article or go to the source images on Neptec's site (and caption info), you'll notice it says it's a false-color depth image, meaning the color indicates it's depth below the surface according to the scale on the side. The damage is about 1.2 inches deep and a little bigger than your thumb in diameter.

    This isn't really an issue of insulation. It's the disturbance of laminar flow. The laminar boundary layer is actually quite a good insulator itself, especially at Mach 20. The main issue is how much the hole disturbs the boundary layer and what localized heating might result. This small of a hole in diameter, even though it's mostly through the tile, should be mostly negligible. But NASA is treating it VERY seriously and is doing simulations as well as has an arc-jet facility to test on an exact duplicate of the damage. (It's a 3D model of the hole, if you check the video, and is easily reproduced on the ground. It has even been printed out with a 3D printer.)

    Remember that Columbia damage was on the Reinforced Carbon-Carbon (RCC) panels on the leading edge of the wing, not the tiles on the belly. The leading edge is one of the hottest and most critical points where that damage occurred. This damage is generally low risk, and EVA is always risky to some degree, but this might be a great opportunity to test repair procedures. When people talk about whether NASA is making decisions based on schedule for this damage, it's not about ignoring risks for the sake of schedule. Risk wins, easily. The schedule issue is that if the damage is not a risk at all, is it prudent to fix it anyway to test procedures and have an actual flow repair to analyze upon return. Remember, EVA and extending flights adds risk to the crew too, but can be beneficial and reduce risk both for this flight and future flights.

    This sort of thinking reminds me of Carl Sagan's lesson of the Marsh of Camerina in Pale Blue Dot. For those who haven't read this brilliant book, it's a metaphor (technically, and analogy I suppose) for creating worse problems in your attempt to solve a problem. In this case, the inhabitants of Camerina drained a nearby marsh to halt the spread of disease that was killing many of them. And it worked. Except that the marsh was also an effective barrier to keep out their enemies, who subsequently attached through the now empty marsh and slaughtered them all.

    "This is exactly what patents are all about."

    Personally, I'd change the wording to "This is exactly how patents are used today." Patents, including those on algorithms (software is not patentable, despite what many people believe) have a very useful and noble purpose: to encourage people to publish their clever ideas and inventions so that others can learn from them, improve upon them, inspire new ideas, and encourage progress. A world without patents at all is a world of secrets where much effort (and expense) goes into keeping the inner workings secret. Otherwise, what's to keep people from creating and selling exact copies of your work without having to put in the investment of time and money into developing the invention like you did?

    The limited protection that patents offer is a necessary evil meant only as the incentive for publishing the details of the invention, and should be limited to only as much protection is necessary for that purpose. The protection is NOT the intent of patents, nor is it an inherent right of inventors.

    Unfortunately, that noble intention has been distorted and corrupted in a manner exactly as you describe. Now, instead of inventors we have huge multi-national corporations who patent everything including prior art and the obvious and use patent lawyers who are skilled at writing patents that are impossible to understand, such that nobody actually learns how it works AND with the added bonus that anybody who does something similar doesn't realize they've technically violated the patent even if they read it and didn't think it was similar.

    Patents are good. This system is bad. Very bad. Bring on the reforms.

  4. Re:Ownership... - what you do with YOUR goods on Sun's Open Source DRM · · Score: 1
    "It's not a question of trust, but rather of ownership."

    This is the key point of contention, but you miss the point of the other side. I tend to side with you on this, but there is some validity (within limits) to the other side.

    All the examples of ownership that people give out, including yours, are tangible property. Very few people would disagree with the assertion you can do what you want with it. (There are circumstances where you can't legally do certain things, but those aren't the point here.)

    This issue is about intellectual property. You actually can't do anything you want with the content of most creative works. If you buy a book, you aren't allowed to copy the whole thing and give it or sell it to someone. Same thing with a CD. (There are exceptions of course, such as in Canada where there's a levy on recordable media that compensates for "personal copying".)

    The saving grace for the content providers has always been that content has been tied to a tangible medium (books, CDs, records, tapes, DVD, film, etc.). In that case, the violation of copyright is naturally limited by the practicality of copying and distributing the associated tangible media. In order for it to be widespread, one needs to invest money and time in the operation and hence require payment at the other end. These copy-for-profit operations always have been (and should be) hunted and prosecuted.

    The issue at hand here is that, when you now buy a song digitally, there is no tangible medium required. There is no cost on copying. There is no cost on distribution thanks to the internet. So there are no limitations of practicality anymore. This isn't (primarily) and issue of losing rights that we used to have. It's an issue of putting back a safety net that used to be there, and aren't anymore. I hate to say it, but it's the content providers that are losing a lot more in terms of effective rights in this. With tangible media gone, the inherent protections of practicality that came with them are gone. They've lost that. The safety net is gone. If we continue to ignore that then we will lose the argument.

    In order to for us to make convincing arguments, we need to demonstrate that they are safe even without the safety net. If we can't then perhaps a replacement safety net, such as some form or DRM, is necessary, and justifiably so.

    This needs to be an issue about what copyright is about, why it exists, what limited rights the content creators should have, what rights the users should have, and how to protect the balance. We want to keep the rights we always had, but so do they. If we keep making this an issue about "it's mine, I paid for it and I'm going to do what I want with it", we'll lose and we should. Copyright is useful when done properly, but is misunderstood and misused on both sides. You can't ensure a balance by only focusing on one side which both sides are guilty of. (I used "we" and "they", but a lot of us are both creators and users.)

  8. Re:I mostly agree on NASA Priorities Out of Whack? · · Score: 1
    I would tend to agree somewhat. However there is one huge hole in the complaints and arguments. NASA has a lot less control over its priorities that most people think. It gets its priorities largely from Congress. And despite the implications of the article, it is not driven largely by Congress members with shuttle contractors in their districts. Yes, the shuttles are old technology and the ISS has little resemblance to its original intention. But there are international agreements here and huge cancellation fees in many cases. For financial and political purposes, there's very little choice here but to finish the ISS, and this relies heavily on the shuttles. To top it off, they are bound to the Columbia Accident Investigation Board recommendations for shuttle flight safety, hence the large costs in getting the shuttles and flights to meet these standards and extension of schedules to meet ISS commitments.

    There is a plan to retire the shuttles and still support ISS, but it's not like they can do that tomorrow. It takes years of development which IS going on right now.

    As far as the Moon and Mars, manned missions versus probes and robotics, science, and deflecting asteroids and comets, there are quite polar opposite opinions out there. The article argues one case, but the author doesn't indicate why the priorities he suggests are more important than other priorities. When he "boils down" the net worth of NASA Life Science research to "billions of dollars spent for astronauts to take each other's blood pressure", it's clear this guy is not the least bit objective or knowledgeable about what NASA actually does. This is the opinion of a "couch" space expert, which is about what his interest in manned exploration amounts to -- sitting on the couch. NASA was created essentially for manned space flight. Some people are content to stay here and let robots do all the space work. Would North American society exist today if that was the extend of the exploration will in Europe 500 years ago? (Exploration which was, by the way, largely driven with interests in financial spin-offs.)

    Does NASA, or Congress, have its priorities straight? Perhaps, perhaps not. Much of it is a matter of opinion. Much of it is a matter of existing commitments. Much of it is drvien by economic considerations. But in any case, this article is one of the worst analyses of the subject I've seen.

    "existing facial rec systems have been known to fail..."

    2D versus 3D, my friend. 2D cameras measure reflected intensities from a given perspective, and therefore are prone to problems with (a) reflectivity/lighting, (b) the viewing perspective, and (c) other things in the image (occlusions, clutter). 3D directly measures the shape of the face, which is harder to change than you think. (Really, it's the shape of the skull that primarily dictates the shape. Only certain areas of the face can change much and don't largely affect the verification.)

    However, this too isn't all that "revolutionary" as the article suggests. Real-time 3D range images have been around for 5-10 years, especially using structured light (some even faster than 40 ms), and robust 3D face recognition algos have been around for almost as long. There just haven't been any/many commercial products yet, and this example is also in the lab, so it's more or less at the same implementation level as 3-5 years ago with similar systems.

    "As someone who works on validation of computer target recognition, I recommend being very skeptical."

    As someone who has written, studied, tested, validated, and worked with 3D target recognition and facial recognition algorithms, I agree to a point. I only agree because it's always good to be skeptical of these things until the (unbiased) evidence has been presented.

    That being said, the jump from 2D to 3D recognition is nothing but revolutionary in terms of recognition and verification accuracy. Beards, cosmetic surgery, and even swelling are not major impediments. They do reduce the match, but less than you'd think. There are areas of the face that don't change much even in such cases. 3D face recognition is more about measuring the shape of the skull. The skin generally follows the shape of the skull except where there are heavy fat deposits, or of course if you grow a beard. Unless you're changes were to the extent of a normal face to something like the Elephant Man or Eric Stoltz in "Mask" (no, not the Jim Carry movie), it's still going to do quite well.

    And even then, the application here is verification. If the changes were enough to make it fail, that would just mean you'd have to go through either a secondary manual security check and/or update the biometrics. It's not like you could, say, pretend to be Tom Cruise and say your face changed. If you don't look like Tom Cruise with a beard or fatter face, and have the same shaped skull, and have the other security info to back you up, you're going to get your biometrics updated.

    As a general comment (not specific to the parent post), I know /. likes to pick apart these things, but /. readers are not of so superior intelligence that they can come up with flaws in 2 minutes that experts in the area of research have not addressed, studied, or solved in years of research.

    "Uh, yeah, because facial recognition software is so accurate."

    Actually, I've worked on 3D facial recognition algorithms and they can be incredibly accurate. You are correct that 2D facial recognition algos have limited accuracy, but that's largely because 2D cameras merely measure the amount of light reflected into each pixel, so any real-world dimensional measurement is an interpretation of feature locations and extrapolated into 3D. Perspective views is big problem as are lighting conditions, clutter, and disguises.

    A 3D sensor directly measures the 3D shape and can fit it quite easily to the reference model. We've done 3D face matches with wigs, glasses, and beards at the same time and still correctly identified the person. You really have to cover up a significant amount of the shape of the face to fool it.

    And even then, that was for identification. This application is verification, so a disguise would be counterproductive. You'd have to take someone with a similar face shape and use professional face-shaping make-up (like for movies) to make an identically-shaped face to fool it into believing you were someone you were not. Not just one that looks the same, but is actually the same size and shape. Hard to do, especially without someone clearly seeing you are wearing the fake features, despite what Mission Impossible or other movies make us believe.

    That being said, I don't know the statistics on similarities of faces. I would certainly bet identical twins could fool it, though I'm not sure how identical their face shapes are statistically.

    In an absolute sense that might be true in that very few bands make a living in general from music. However, relative to sales of recorded music, bands make most of their money from touring and merchandising. Basically, the artist "cut" of the CD sales goes towards paying back the "loan" for the recording work (including salaries, catering, etc., etc., over which the artist has little or no input). Most of what they make on tour is theirs to keep, minus the direct costs of the support staff. Yes, this can be substantial on big tours, but they also make bigger money. The point is that you can take the revenue and subtract the costs directly and see how much per show you are making so you know when you are losing money. CD sales are a cross-your-fingers-and-hope that you make back enough to cover the "loan" you contracted for.

    Only the biggest artists make much income from commercial music sales (not home-recorded CDs), and that's because they're big enough to dictate better contract terms and make back the recording costs quicker and easier.
