  1. Re:Why not collect energy on the way down and... on NASA's Test Bed For Mars Chute: Kauai · · Score: 1

    Considering that the most problematic aspect of landing on a planet is a surplus of (kinetic) energy, why not find a way to take a long glide through the atmosphere while converting some of that energy and storing it in a form that can power a propeller, rocket engine or other device to slow down the last phase of descent? The air friction from this energy collecting phase would also serve to slow down the descent, making the final phase all the easier.

    As far as forms of energy which could be converted to for storage: there's the possibility of converting CO2 to carbon carbon monoxide and oxygen; there's charging batteries to power a helicopter propeller; and ...? I don't suggest that these are practical methods of storing and using surplus energy --- they're just starting points.

    Hmmm, I wonder if some of the principles of scramjet design could be used in reverse for braking? If you're making compressed O2, you'll need a way to bottle it in a hurry without creating excessive hazards for the crew. Anyhow, I'm glad someone's finally recasting the term "Martian flying saucers".

    Key question: do you need to work with MS Exchange? If so, ask yourself whether you have a suitable replacement for MS Outlook. Pretty much anything else, office workers can adjust to, but most live in Outlook. Not being able to identify coworkers, set up meetings, in the familiar way is damn-near an impossible sell. Thunderbird etc isn't really a convincing answer. Of course, if you moved all that onto their personal smartphones first, then the proposition changes...

  12. Re:Linux kernel on Ask Slashdot: What Do You Consider Elegant Code? · · Score: 1

    Code quality in the Linux kernel varies a lot per individual driver or subsystem

    Well, Linus uses a broader definition of kernel than is customary, referring to a monolithic (macro) kernel. If you really seek elegance in OS code, you start by looking at microkernels, stripped of all the device-dependent clutter. Harmony, for instance was a mere 20 kbyte kernel, even on 68K architectures. http://books.google.com/books?id=xvOpC0_r14wC&pg=PA100 http://www.researchgate.net/publication/234826460_Harmony_as_an_object-oriented_operating_system This led to the even more succinct MQX, which is embedded in quajjillions of devices.http://en.wikipedia.org/wiki/MQX

    Placebos are pretty well understood. The BS enters when you pretend that one sugar pill is vastly more valuable than another and charge accordingly. Of course big pharma does the same with real drugs (look into "evergreening" sometime), but for them, it's more of a sideline. The basic idea is still to find treatments that actually do work better (and safer) than currently available options.

  15. Re:You know what they call alternative medicine... on Jimmy Wales To 'Holistic Healers': Prove Your Claims the Old-Fashioned Way · · Score: 1
    There's a reason there's an entire field called evidence-based medicine [wikipedia.org], which from its very name makes it distinct from just plain-old normal "medicine."

    If you prefer, we could just distinguish "real medicine" from "pretend medicine"... Of course individual practioners use a mix of the two, particularly when there's no real treatment for a diagnosed condition that is either untreatable or harmless. That in no way makes pretending a full-time substitute for evidence.

    You've forgotten that the Hz represents cycles/s, not just 1/s. Hence their so-called "spectral efficiency" is 5.7 bits/cycle. The problem of course is that the article does not address the SNR nor the BER that it took them to get that 5.7 result. If you need cryo-tech photodetectors and massive FEC to get that result, it's less impressive than doing it with the existing kit and minor data redundancy.

    The real point is that she should be allowed to refer you to someone who is allowed, in this case a dermatologist. The whole GP-as-gatekeeper issue is really profit-driven disfunction. Of course, in most jurisdictions medicine is a self-regulating profession statistically dominated by GPs, so it may be a while before that changes.

  23. Re:A cobbler should stick to his last on 4 Prominent Scientists Say Renewables Aren't Enough, Urge Support For Nuclear · · Score: 1

    Interesting analysis, but the conclusion is wonky. The problem you highlight is caused by two things: grossly distorted pricing structures intended to subsidize "renewables" and perception-skewed design safety profiles (out of all proportion to real risk) that artificially jack up the cost and delay the approval, build & commissioning of nuclear while encouraging the burning of more dangerous fossils or the broiling of birds in sunbeams. For the most part, totalitarian states don't have these problem, they can do the sensible thing without worrying over NIMBY. Odd though, that China keeps building coal plants despite their access to nuclear.
