  1. Re:Reality closer to SciFi, SciFi != Fantasy on Has Sci-Fi Run Out of Steam? · · Score: 1

    I agree that prognostication gets harder as technological progress accelerates (as do gripping science fiction premises), and that science fiction is becoming less fantastical because we are so familiar with technology similar to what we find in those stories. What seems to be missing these days, however, is the social, human element. For example, growing up I read a lot of golden age science fiction, most of the technology of which has been either now realized, or seems utterly laughable. (As an odd result of this, I've spent the better part of the decade thinking of myself as "living in the future".) In most of those stories, the technology featured prominently as a MacGuffin, a starting point for the real story.

    So you have cheap nuclear power, enough to waste in broadcasting it wirelessly, and everyone says its safe. How do you know? What do you do when you find out it's not, and the most transformative 20 years in history prove a colossal mistake? So you have institutionalized slavery (robots), not just over bodies, but minds. How do you keep the system running? Is it even moral to enslave something you've built from the ground up? So your entire economy has come to rely in some way on a single cheap service. To what extent are the people offering that service entitled to run your society? Most of these questions have been touched on and answered again and again in science ficition, but the common element is not technology. Rather, the common element is how people cause and react to change on a grand scale.

    Unfortunately, many readers tend to fixate on the technology itself, and the social message (the real meat of the tale) gets lost. After that, you degrade into what we have now: science fantasy. Exercises in world-building for the sake of world building, exotic new toys like lightsabers, super-science that acts as an instant stand-in for magic, and all the other little bits that used to be just scenery moving center stage. There's just enough there to look like science fiction, when all it really is is adventure fantasy.

  2. Re:Maxwell Equations on Researchers Discover "Magnetic Current" · · Score: 4, Informative

    Making the equations "symmetrical" for both electric and magnetic charges does not make them any more elegant or powerful

    Discussion of the existence of monopoles or true magneto current -- seriously, people -- this sentence is glaringly false. In fact, the use of magnetic charge and magneto have been integral* to electromagnetic analysis for more than 50 years now. Using the symmetric form of Maxwell's equations. The fields created by all sources and media inside an arbitrary closed surface can be analogously modeled as charge and current distributions over the surface. This is what allows you to equivalently model the open end of a driven waveguide as a rectangular patch of magneto current, an electric dipole antenna as a "cigar band" of magneto current wrapping around the feed gap. All of which, I should add, makes the equations much easier to solve. Hell if nothing else the addition of a magnetic boundary conditions can allow numeric models to converge much more quickly.

    Arguing that the phenomenon discovered does not truly uncover a magnetic monopole is one thing. Arguing that there is no benefit to symmetrical equations is as silly as that there is no benefit to expressing the equations in the "bastardly" phasor vector notation when a simple set of 12 differential equations of 12 variables would suffice.

    *No pun intended.

  3. Re:Eyecandy in cost of usability on Firefox To Replace Menus With Office Ribbon · · Score: 5, Insightful

    Another important thing to remember that menus hide unused and rarely-used features. In most modern software that's actually a pretty good thing, as very few people need or want to leverage every single feature of an application in one session. It makes it harder to discover those features, but once you learn where they are the first time around, it's a solved problem. By presenting the user with large blocks of mostly unwanted toolbars, the ribbon scheme steals valuable vertical space without offering any usability savings over the initial discovery. You still have to switch between ribbon states to find half the features you want, and select from drop-down lists of icons insted of drop-down menus of options.

    This will mesh better with Microsoft's vision of a modern application, for what that's worth. It might make some features easier to discover (I know people who are still surprised to learn about Firefox's keywords feature). Even so, I doubt it will be more popular than the current design, lead to significant changes in the way people use Firefox's features, or be worth the loss of valuable vertical real-estate. The only good thing I can say about it is that most people don't need to use menus in Firefox as it is, and the ribbon can probably be hidden like the URL bar, menu bar, and toolbars can already be hidden.

  4. Re:Ignorance is bliss on Apple Says iPhone Jailbreaking Could Hurt Cell Towers · · Score: 4, Insightful

    They're not really playing to the ignorance of their base, as it's not their base that they're trying to convince. They're trying to convince the Copyright Office, which is almost as bad because they cannot be reasonably expected to understand the intricacies of cellular network technology. That burden lies with the network operators and the FCC. As for the question of whether jailbreaking is good policy from a copyright perspective, the Copyright Office shouldn't care much about potential network problems.

    Now from a technical perspective: AT&T is a GSM/EDGE/UTMS network. If the iPhone is supposed to work on their network, it conforms to those international, well-vetted standards. (An part of those standards is the use of a SIM card specifically so a user can separate the handset from the network.) There shouldn't be anything that an iPhone can do on their network that any other cell modem couldn't do. TFA isn't coming up for me, so I'm not sure what Apple's specific claims are, but I have a hard time imagining that AT&T gave them some unique, magic software key to a very well-defined tower structure.

    Unfortunately, taxes are part of the problem in Michigan. Businesses just can't afford to operate under the tax burden there, so they were fleeing the state even before the recession. States have to compete for cash just like everyone else. Just like a vendor can cut prices and make it up in volume, so too can a state lower taxes and make it up in an increase in business. That such drastic cuts are necessary is not just a sign of the times, but also a sign of a state that just refuses to compete.

    In general, I find the books I want to read either 1) get popular enough that they eventually drop down to a reasonable price, 2) are just popular enough that it's available without a wait at the library, or 3) is so obscure that I can buy one of the 30 copies that are actually still available for a couple of hundred bucks on Amazon.

    Note that the one I would most be interested in an electronic copy of (legal or not), is the one that is least likely to have an electronic copy.

    There are only a few books out there that are both popular enough that a good number of people want to read them, and yet not popular enough that buying the book is actually easier than hunting down the torrent or scanning yourself. Those writers will probably get hit hardest, and the gap between immensely successful writers and sort-of-successful writers may widen because of it. As an industry-wide problem though, I doubt it'll ever have the effect that it's had on, say, the music industry.

  10. Re:In a word... on Obama Proposes High-Speed Rail System For the US · · Score: 1

    The trouble is "regional" here means almost exclusively "the northeast". There are two great commuter sinks -- New York and DC -- that produce enough jobs by virtue of the industries that are pretty much stuck there. People have to commute in from somewhere, because the cities just can't support that many full-time occupants. You have many dense housing areas within an hour or so of a few dense work areas.

    In most of the rest of the country, that just doesn't hold: a commute doesn't mean an hour on a train so much as 15-30 minutes in a car. Trains are a less than ideal solution, either because the housing areas are too sparsely populated, or there's no single major work commute destination, or the housing ares are too spread out to justify the claim that a handfull of stations can actually reduce the total traffic. Congestion just shifts around, and the time commuters thought the would save is lost trying to get to the trains.

    Also, the densest cities -- which probably have the most congestion and could benefit most from rail -- would have to reclaim land from existing roads, thereby worsening congestion for all motor traffic so that a train carrying a few people can pass by once every half-hour or so.

    Trains make sense when you have a lot of fairly dense areas within a hour's drive of each other that people frequently travel between. Japan, parts of western Europe, and the American northeast fit the bill. America as a whole does not.

    "We're Not Entirely Honest" = We've been lying

    Actually, "We're Not Entirely Honest" = "We have no idea how to give you an accurate estimate." As someone whose found himself sucked into the battery/mobile power side of a project recently, I can understand why they'd face difficulties.

    When it comes to batteries, there are really only three options for measuring how much power is stored: completely drain it over several cycles to see what you get (which is how the manufacturer confirms capacity, but isn't too useful in situ); test the voltage across the terminals and estimate absed on pre-measured battery curves (which is difficult because voltages don't change dramatically until they're nearly drained); or, in some chemistries, measure the temperature changes in the battery (which detects inreactions that don't happen until the battery is almost completely drained). In practice, all you can do is take the manufacturer-specified capacity, derate that based on conditions in your application, and test to see if you came close.

    In general, pulling more current from a battery disproportionately decreases remaining capacity. In general, it's pretty difficult to respond to sudden surges and lulls in power consumption for a user's unknown power cycle needs without making your estimate jump all over the place. In general, the problem is just a pain in the neck. It's like ordering a margarita with margarita-flavored ice cubes from a waiter whose never seen you before, then demanding to know exactly how long before you'll need to refill it (regardless of whether you intended to chug it or nurse it).

    I'm no expert, but you don't have to be to see it's not a trivial problem.

    This particular comment (the parent) is actually one of the few good comments I've seen so far.

The fact that you never got around to depositing the $10,000 is irrelevant: the teller saw $10,000, and it still has to be reported. (True story; very dumb drug lord.)
