  1. Re:Photographic prints! on Ask Slashdot: Best Option For Printing Digital Photos? · · Score: 2

    The best bet for long term preservation is digital storage by a third party that is focused on preserving the data that is put in its care. Yeah, I'm talking cloud here.

    The other part of this is to put the images into a lossless format that will be around for a few decades, and is so broadly used that you can be sure there will be a means to migrate the images to the next format when the one you are currently using becomes obsolete. For most photos, that means converting to .png (portable network graphics) format (.jpg is lossy and lacks a few useful features). Pros and high end amateurs should explore the .tiff format. I don't think anyone would consider .raw a suitable long term archival format.

    The .xcf format might become the format of choice for archiving, it offers a lot of advantages. But it is probably 5 years too soon to judge its staying power.

    It is another type of photoshopping. And I mean this in a good way.

    A perfect photo does not need any help, but how many of them have you, or anyone you have known-- even the professionals-- ever taken? All other photos can benefit from a little post work.

    Printing to canvas or some other texture can make an almost-good photograph look wonderful, and a would-be-perfect-except-for-something look exceptional. We are talking art here, not a precisely accurate reproduction of reality.

    Using Photoshop or the Gnu Image Manipulation Program to do the post work really well is not an option for hobbyists with thousands of photos to process and no time to devote to learning all the techniques. Printing to a textured surface is a quick and easy way to often get better results than what comes straight out of the camera.

  3. Re:Not only that... on Some USAF Pilots Refuse To Fly F-22 Raptor · · Score: 1

    What has been spent on these has probably been well spent. We now have 180+ F-22 fighters that are more than a match for anything that China or any other nation can put into production in the next 30 years.

    But as anyone who bothered to RTFA would know, the remainder of the F-22 program, to build the fleet to 600 planes, has been canceled. Which makes perfect sense, as there is no need for any more of them within the service life of the existing fleet.

    Some money is still being spent on developing the fighters that will become the F-22 replacements. Most of these future fighter planes will likely be drones capable of mid air refueling by other drones, and with no finicky O2 systems to worry about. Oh, and drone pilots are very well protected from the perils of blackouts, hypoxia, and such, and are much better at keeping a cool head and making good decisions in the midst of aerial combat.

    Keep practicing on them video games. You just might become a USAF ace fighter pilot when you grow up.... without ever having to leave your basement or go into the big room with the blue ceiling.

  4. Re:Need comparison with competitive aircraft on Electric Airplane Ready For Production · · Score: 1

    Good points.

    The loss of efficiency of using a pusher prop will be mostly offset by the gain in efficiency in using a canard wing. Traditional tails adjust the angle of attack of the lifting wing by exerting negative lift to pivot the plane around its center of lift. Canards use positive lift to adjust the angle of attack of the primary wing. IIRC, in a standard airplane on take off, the tail increases drag by something like 15%, enough to require a bigger engine than is needed for level flight. But a canard wing increases lift by usually around 20%, and putting the two together you can get a lot more performance out of a much smaller engine.

    Not to mention the safety factor: canards can be designed to stall before the main wing does, resulting in porpoising rather than making like an auger.

    Also IIRC, the main difficulty with canard designs has always been managing the control systems, which has required much more complex mechanical linkages than a traditional plane. But if you go to fly by wire, the computers would handle all of that (naturally you would have redundant computers).

    I don't know that a person would necessarily "experience" RFI between components on a rack that were not properly shielded from each other. Moving a cheap portable AM radio around the rack might reveal a very bad problem, but would not rule out a milder problem that could still be causing corrupted signals. The computer users would not necessarily realize things were not right since the protocols are pretty much self-healing. It would just be that all that money put into a fancy system might be buying no better throughput than a cheap system would provide, as the system would be operating at much lower than 100% of its specified efficiencies as packets and data streams are rejected and repeated, etc.

    It would be really nice if someone who knew a thing or two about signal processing in a noisy environment would jump here.

    In the meantime, I would suggest that persons interested in putting bare MBs on a rack look into the reasons why standards compliant computer cases are built to be Faraday boxes.

    PP's first point is undeniable. Slashdot has become home to a lot of high school know-it-alls, and of course geekdom has always had a large number of persons who retain their prepubescent inflated ego problems into their twenties and later.

    The second point is not valid. With several nations now discussing lunar bases, Mars expeditions, middling high Earth orbit habitiations, etc, there is a lot of very common stuff that could be mined from asteroids very profitably. Ice in lunar orbit will be worth a great deal. Any oxides that could release O2 in solar furnaces would make a miner wealthy. An ounce of frozen methane Up There would be worth much more than an ounce of gold down here.

    Asteroid miners are betting that China, India, the USA, or Russia-- or some private corporations-- will continue to move into space; that a market will develop for their goods near their point of sales. To me, this seems like a reasonable bet for a wealthy man. For if something disrupts human progress into space, it is going to disrupt any other investments a truly wealthy man could make.

  14. Re:Time delay - info from the future? on Quantum Experiment Shows Effect Before Cause · · Score: 1

    A serious problem with these kinds of experimental structures is that they fail to take into account the indeterminate time of the observations.

    It is not just that the states of the particles are indeterminate until they are observed; it is also true that the exact timing of the observations that collapse the probability waves are also indeterminate. The most we can say with any accuracy is that the observation occurred sometime before the article was published. But did each observation occur when it was recorded by an instrument, or at some moment after that, when the observer first saw the record? Until the record itself is seen, the recording is pretty much just another cat, isn't it? Or maybe the actual observation occurs some indeterminate time after the photons from the recording device were processed through the retina, the optic nerve, the visual cortex, and finally recognized by the observer's consciousness? Or perhaps the true observations do not happen until Alice, Bob, and Victor get together to talk it over; perhaps until then there is only uncertainty about what has happened / is happening since only until that time can each of the three be certain that no glitches interfered with the others' work.

    So if we cannot accurately determine when the observations were actually made, nothing can be said about the order in which the events "really" occurred. "Really" most definitely in quotes here, since this whole discussion is about a region where reality is plastic, possibly fluid, and possibly not even there.

    These kinds of experiments do not do QM justice; they are merely parlor trick exercises in trying to exclude the observer from the process so that QM could be treated like another simple model of levers and pulleys like all the best that classical physics has given to us. But the core of QM is that the consciousness of the observer is inherently bound up with the observation.

    Physics needs to know a lot more about the process of observation before it can talk sensibly about a cat in a box, or whether the chicken preceded the egg.

    Oh, for all the kiddies out there: FORTRAN for FORmula TRANslation: first compiled language, circa 1955. COBOL for COmmon Business Oriented Language: first real compiled language, circa 1960, developed with speed typists in mind. (Hence arithmetic operations were spelled out: "ADD", "MULTIPLY" rather than "+", "*". The bottlenecks were different back then.) Bit bucket: the tray under the punch card machine that caught the little bits that were punched out of the Hollerith cards. Later on, a guy named Chadless developed pre-perfed cards where the holes were made by folding back the tabs rather than punching through the card; these were called Chadless cards. So naturally the stuff that accumulated in the bit buckets of the older Hollerith punch machines became known as chad. (Loose chad was not good, it would get into the guts of the punch card machines and cause jams, or worse, get carried into the computer room itself in card decks, and break card readers and high speed tape machines.)

If he stays with programming, then he will need to learn more than can easily be done in javascript, but that is down the road and around the bend. If he never goes any further than javascript, he will still know a thing or two about tricking out a web site, etc, that will help him more clearly present himself in college, etc.

    The best first language, though, is going to be the one being used by some project that he has gotten involved with. For example, Blender is a FOSS 3D modeler and animation package that has standardized on Python. There are some music - MIDI - mixing packages that use Perl. Some websites he might want to contribute to run on Rails. These all offer kid-accessible APIs that are like virtual Lego sets (for that matter, Lego's robotics are pretty cool, I think they use Forth). So maybe he should be encouraged to select a project and get his feet wet with whatever that project is using. If he ends up switching languages a few times as his interests change, so much the better. Learning how to quickly learn a programming language is a major skill set of its own.
