  1. Re:Cargo only on Liquid Oxygen from Lunar Rocks · · Score: 1
    NASA disagrees. Saturn and Venus both have surface gravity about 9% less than that of Earth.

    Anyway, it's really a moot point. I only said it because it makes a good sound bite. Surface gravity is not a good measure of the difficulty of leaving a gravity well. Escape velocity is a better measure, and atmospheric drag should probably be factored in too. Besides, the "surface" used for the gas giants is the tops of the clouds, which is really not a meaningful altitude.

    I can't see ... how spinner energy can launch anything off Earth.
    So what? That was never the claim.

    Hopefully, being stuck at the bottom of one of the strongest gravity fields in the solar system is a temporary condition. (Only the Sun, Jupiter, and Neptune have higher surface gravity than Earth.)

    What are you talking about? Snapshots print just fine at 5x7 on my Canon printer. I did the math one time, and I think they cost half as much as a photo lab, but even if it's a bit more expensive, it's much more convenient.

    One downside is that the inks are water soluble, so you need to frame them properly (like a watercolour painting) if you want them to last.

  5. Re:Where do they get these numbers??? on Linux Has Fewer Bugs Than Rivals · · Score: 2, Insightful

    I think they must be counting compile-time errors.

  6. Re:What about the ones they missed? on Linux Has Fewer Bugs Than Rivals · · Score: 1

    Yeah I was thinking the same thing. That's utterly pathetic, unless they're including such "bugs" as compile errors (in which case it sounds about right to me).

    Dude, you don't have to add the domain in brackets after the link. Slashdot does that for you.

  8. Re:But we already have guys up there. on Astronauts Should Fix Hubble · · Score: 1
    It's an absurd proposal. Changing orbits like that takes impossible amounts of fuel. It would be easier to launch a new Hubble than to move the current one. (Something like how it's easier to go from 0 to 60 on the highway than to turn around from going 60km/h in the wrong direction.) Besides, once the Hubble is in ISS's orbit, it wouldn't function properly anyway because of atmospheric drag.

    What would have been smarter would have been to put the ISS in a useful orbit in the first place. It's in a bizarre highly-inclined orbit just so the Russians can get there from Russia. From all other perspectives, the ISS's orbit is useless.

  9. Re:To Quote Steve Jobs... on Introducing The Heron Programming Language · · Score: 3, Informative
    I commend the designer of the Heron language for trying to simplify some of the complexity of C/C++ (Just like the D language and Eiffel tried)
    Actually, Eiffel predates the first edition of The C++ Programming Language, and was much more influenced by Ada and even Smalltalk than by C++.

  11. Re:What happens when it's not secret anymore? on Is Some Software Meant to be Secret? · · Score: 1
    I guess I'm biased against any system that relies on the courts to settle patent issues, because that implies lawyers and legal costs and all kinds of things that weigh in favour of big businesses.

    Having a patent issued should be a fairly reliable indicator that it's safe to disclose an idea without having someone else make all the money from it. Otherwise, what is it for? So if the patent office can't give some reasonable assurance that issued patents are valid, then I think they just ought to stop trying.

    That basically sums up my point of view on the topic, but I must admit I haven't given it a great deal of deep thought. How does your system help the little guy?

  12. Re:What happens when it's not secret anymore? on Is Some Software Meant to be Secret? · · Score: 1
    The validty of specfic patents can then be determined in court, as necessary, where both sides of the issue can call real experts from those fields.
    No way. This just makes the system that much more inaccessible to the individual or small-time operator who can't afford a lawyer.

    Bacteria are very complex life forms. They may not even have had a chance to evolve in the first place if all the oceans and lakes of the world (1) froze solid every winter, and (2) were permanently frozen beyond a depth of 30 metres or so.

    Mysteriously dimmed menu items

    I don't necessarily agree these are bad. The alternatives are removing them (bad because menu structure changes), not disabling them (makes no sense - they are disabled because they aren't meaningful right now), or not dimming them (bad because you don't signal the action is unavailable).

    You missed one. Keep the menu item dimmed; but when the user clicks on it, don't simply ignore the click. Instead, tell the user why the item is dimmed.
