  1. Re:Pound of pressure? on Ikaros Spacecraft Successfully Propelled In Space · · Score: 1

    It is correct grammar to refer to pounds of pressure as pounds are units of force. A narrower definition of pressure is, of course, force/area. Anyway, I much prefer the usage of pounds for units of force than grams or kilograms.

  2. Re: Use scientific units... on Ikaros Spacecraft Successfully Propelled In Space · · Score: 1

    By which point pounds and ounces almost make more sense.

  3. Fort Peck dam is 6,409 wide on Beaver Dam Visible From Space · · Score: 1

    The Fort Peck dam was completed in the late 1930's, it's on the Missouri river just south of Glasgow, Montana (where I got my check ride for my private pilot's license).

  4. Re:Timelines on Microsoft Gets Back Its FAT Patent In Germany · · Score: 1

    I mean, FAT is like 20 years old.

    More like 30 years old (QDOS) to 34 years old (M$ Disk BASIC).

  5. Re:Credibility on Climate Researchers Fight Back · · Score: 1

    That's the most insightful comment in this whole discussion.

  6. What's with the CO2 obsession? on Climate Researchers Fight Back · · Score: 1

    Generating CO2 is just one of many ways that man can affect the climate, there are several other gases that strongly attenuate IR, all sorts of aerosols and don't get me started about contrails.

  7. Re:Not a Soviet first? on First Weather Satellite Launched 50 Years Ago · · Score: 1

    I did and even had heard comments that the TIROS was a first stab at a recon satellite (though the Hubble 'scope borrows much more from recon satellite technology).

  8. Re:Questionable "first" anyway on First Weather Satellite Launched 50 Years Ago · · Score: 2, Informative
    You would be surprised how little it can cost to track satellites. Ever hear about the satellite tracking work done by an English school teacher and his students? They had both deduced that some Soviet sats were photo recon and that the Soviets had a new launch site.

    To be useful, a weather sat needs to download the data in near real-time and AFAIK there was no record of any Soviet bird doing that before Tiros.

  9. Re:Not a Soviet first? on First Weather Satellite Launched 50 Years Ago · · Score: 2, Interesting

    Eisenhower was especially worried about the Soviets reaction to a launcher developed by von Braun's group - they could have had a bird in orbit in January 1956. Eisenhower ordered personnel at the Cape to make sure that there was no fourth stage on that launch.

  10. Re:Not a Soviet first? on First Weather Satellite Launched 50 Years Ago · · Score: 1

    A weather sat with a better camera is a spy sat.

    You're forgetting one important difference: weather satellites need to return imagery in real time or near real time - getting a film of a hurricane forming doesn't do a bit of good if it arrives a week after the hurricane makes landfall. Besides that, a 1km resolution is adequate for most weather imagery, but very little use for recon.

  11. Crash Telecommunications Services - #62 on 25 Years of the .com gTLD · · Score: 1

    My first ISP was CTS.COM, had an account from 1995-2003. Would still be with them, but they dropped their DSL biz in 2003. What's funny is that the DNS entry for my host still resolves...

  12. Re:Help me benefit from media hype on Toyota Acceleration and Embedded System Bugs · · Score: 1

    What if the Prius is a rental or loaner car? I had a recent experience with a rental Subaru - both the headlight switch and windshield wiper switches were in non-standard locations - took me a lot of fiddling to find where each was.

  13. Re:Of course, there is an alternative theory... on Toyota Acceleration and Embedded System Bugs · · Score: 1

    As for the clutch, how long do you think it will be before car companies decide to remove the direct link from the clutch pedal to the clutch and replace it with electronic control to improve reliability and shifting?

    Don't forget emissions control reasons. There have been times in the past where manual trannies weren't available in California specifically due to the tighter reg's in CA.

  14. Re:Impossible to test on Toyota Acceleration and Embedded System Bugs · · Score: 1

    And if you look at the facts, you can see that all of the symptoms could easily be caused by driver error.

    There's a big difference between could be caused by driver error and actually being caused by driver error.

    The aviation industry has recognized that many examples of "pilot error" were caused more by poor design decisions by the manufacturer than by poor decisions by the pilot. Similarly, the TMI accident of 1979 was as much caused by poor control room design as it was by poor training of the operators.

  15. This is where Toyota screwed up on Toyota Acceleration and Embedded System Bugs · · Score: 1

    I don't think anyone at Toyota realized just how bad their handling of the event recorder data looks. I'd be much more willing to give them the benefit of doubt if they were as open with the data as GM, but this comes off as incredible arrogance.

  16. Re:Help me benefit from media hype on Toyota Acceleration and Embedded System Bugs · · Score: 1

    Some of these vehicles don't have keys: just a radio remote. The emergency shutdown procedure is to hold a button down for three seconds (another design defect).

    I would use a stronger term, it was an incredibly stupid design decision. I wouldn't be opposed to a federal regulation specifying that there is some method of shutting off an engine within one second - really easy to do with a traditional ignition switch.

  17. Compare withmachi machine tools on Toyota's Engineering Process and the General Public · · Score: 2, Interesting
    You made a good point.

    One of the design "features" of the Toyota product involved in the 2009 fatal accident in San Diego was that the driver needed to press the engine start button for three seconds to kill the engine. Can you imagine any machine tool company making a product that required the emergency stop switch to be depressed for three seconds to turn off the machine?

    Another issue with that car was that getting the tranny into neutral was not trivial (sport shifting option).

    Toyota screwed up big-time here.

  18. Re:Ah, I unplugged the atomic clock... on New Most Precise Clock Based On Aluminum Ion · · Score: 1
    As others have mentioned, sounds like a neat way of making a new gravity meter or gravity gradiometer. The gradiometer would probably be more interesting as gravity meters good for sensing a 1 centimeter change in elevation already exist.

    FWIW, I worked with some of the people who were involved with the gravity gradiometer work at the Univ of West Oz.

    Not too surprising as that song was hitting the airwaves circa 1971. Bet there are some slashdotters whose parents weren't even born when that song first aired.

  20. grpn is my favorite on 7 of the Best Free Linux Calculators · · Score: 1

    Obviously an rpn calculator, pretty much the basic trig and exponential (in some ways less than an HP-45 - my first calculator). On the other hand, it does have a deep stack limited by screen space, complex numbers, some matrix ops and an instruction called "rip" - resistors in parallel, which also works with complex numbers.

    Have you ever read about the case that led to the "Shouting fire in a crowded theater"? To save you some time, it was in an opinion upholding the arrest and conviction of people protesting the draft during WW1.

    Chomsky's quote would have more of an impact if he included George Creel before Goebbels - I think Goebbels had Creel in mind with respect to the "Big Lie".

    Airlines cannot function without making substantial use of publicly funded resources (airports, airways, etc) and thus an airliner is thus subject to regulations that may apply to strictly private property.
