    I always thought that testing and debugging were the lengthy manual steps. Oh. Wait. "Time to market". They're talking about proprietary software. Never mind.

    The DMCA is utterly irrelevant to this issue.

    As long as the plastics don't melt (most have higher melting points than that) and the battery electrolytes don't boil (some use nonvolatile electrolytes) it should be ok at 150C.

    > Asphalt is 100% thanks to automobiles.

    The British started paving ("metaling") their roads in the late 19th century primarily for the benefit of bicycles.

    And while the driver is staring at the pretty lights he runs over the cyclist.

    Clever!

    The airframe could drive the rotor with a wavemotor mechanism and feed it predigested nutrients through the driveshaft the same way oil is fed through a crankshaft. The rotor would expel waste through its tips (messy!). The two could communicate acoustically.

    Alternatively the rotating part could simply not be alive. It would develop like an antler and when mature dry into a hard structure. The connection to the body at the shaft would wither and the rotor would become free to spin when drive by the motor mechanism.

    Vibrating rods can serve as gyroscopes of a sort. It's how MEMS gyros work.

    The rotor would have to change shape as it turned to compensate for the effect you describe. Doable, but flapping seems more practical.

    Amazing. All those years using whiteout on typewriters when I could have been using the delete key that I didn't know was there.

    Is this about patents or copyrights? BTW data is not protected by copyright in the USA.

  16. Re:No manual control? on Investigators Suspect Computers Doomed Air France Jet · · Score: 1

    Why are crashes caused by pilot error better than ones caused by software error? Yes, the computers screw up sometimes. If they screw up less often than the pilots would we are better off. Better yet, how about letting the computer fly the plane while the pilot supervises, ready to intervene if the computer goes wrong? Oh. Wait. That's exactly what they do!

    By my calculations 1 m^3/sec of air can carry away 65kW at a 50 degK temperature rise. That's doable, though you don't want it exhausting into your office.

    I think it is doable. The whole machine must be air-cooled but nothing in the RFP says that liquid cooling could not be used internally.
