  2. Re:To really put things in perspective.. on Much Ado About Gas Prices · · Score: 1

    Don't think for a second that gas is actually cheaper than $6/gallon here.
    I'm quite confident that you're wrong.
    I remember reading that the most expensive oil in the world was in... San Francisco.
    At least in France, where gas prices are in the same range as the rest of Europe, I'm pretty sure most of the price is tax.
    Wikipedia appears to be down, the next information I was able to find was here, where it indicates a tax of 60EUR/hL, or .6EUR/L, which should be about 1/2 the price of gas.

  3. Re:equivelent MPG on Google.org, a For-Profit Charity · · Score: 1

    A kilowatt-hour should have a standard number of joules
    1 kWh = 1000 Wh = 1000 W * 3600s = 3,600,000 J = 3.6 MJ

    However for this kind of things it's useful to consider the inefficencies in distribution (e.g. does it 'cost' more to get a gallon of gasoline or the equivalent amount of electricity?)

  5. Re:(sigh) on Voting Machines Wreak Havoc in Maryland Elections · · Score: 2, Informative

    How many candidates per piece of paper? How big should each candidate's name be written? In what ORDER should the names of the candidates be written? When are the ballots printed?
    In France, there's one candidate per piece of paper. There are piles for each candidate; you're supposed to take several to keep the secret (you're also getting some in the mail). Put one piece of paper in the envelope (in secret), put the envelope in the box (in front of election officials). I've never heard of voter fraud in France (doesn't mean there isn't any though)

  6. Re:Strace?! on Sun Wins Top Tech Innovation Award · · Score: 1

    With strace can you trace everything from I/O operations through to system calls to monitor your live application without taking anything offline and get almost no performance hit?
    With strace you can get system calls, without taking anything offline (you can attach to a running process); I don't know about any performance hit (the man page appears to say there are some). I/O operations are usually sytstem calls so they're covered.

  7. Re:Just like there will never be another Doom on Can Anyone Beat WoW? · · Score: 1

    Command & Conquer did the same for RTS.
    That's not true.
    I would say it was Dune II (some might argue it was Warcraft, too).
    The simple fact there's disagreement tends to point that neither is actually a "defining" game.

  8. Re:I may want one of these after all on Microsoft leaks Zune Details in FCC filing · · Score: 1

    Windows + Pause to open System Properties (probably the least used shortcut)
    The least used shortcut? Are you kidding?
    Also Win + L I believe allows you to switch users in XP

  9. Re:Maxwell's demon on Irish Company Claims Free Energy · · Score: 1

    Maxwell's demon has nothing to do with vacuum energy.
    Maxwell's demon allows decreasing the entropy of a closed system (violating the 2nd principle of thermodynamics) but doesn't change the amount of energy present (respects first principle).

  10. Re:Errr... on Firefox Analyzed for Bugs by Software · · Score: 1

    It's impossible to detect logic errors out of the box (cases of "it's a feature, not a bug!"). (At least, it's impossible without "strong" AI, which would "know" if it's reasonable to allow raising the landing gear while on the tarmac).
    It might be possible with techniques such as model checking, but it involves a lot of help from the programmer.

    Sorry about the link.
    Corrected link. Unfortunately there are only 2 examples since there are trade secrets involved with bug reports.
    This might look like a slashvertisement, but I didn't submit the original story (which does pick up on a press release)

  12. Re:If this is the same on Firefox Analyzed for Bugs by Software · · Score: 2, Informative

    These tools can't neither find all bug in your code nor swear that those it finds are real bugs
    That's true. It's impossible to have both (all bugs and no false positives, soundness and completeness), and even one of them is usually extremely expensive (computationally).
    It helps to follow "good practices" and be more precautious
    That's not true of Coverity (disclaimer: I work for them), we find real bugs. You can see a couple examples here. The engineers are usually the ones excited about it, once they've seen the bugs.

  13. Re:Errr... on Firefox Analyzed for Bugs by Software · · Score: 4, Informative

    I hope these Coverity guys aren't pompous enough to think that their tool can find ALL bugs in a program
    We aren't (I'm a Coverity employee). We find real bugs, and we find false positives (but not too many of those).
    Hmm, they should run their tool on its own source code, that would be fun.
    We do that regularly.

    I think you got it wrong. parchment is tanned skin, vellum can be made of cellulose (but is orginally parchment)

    Because NOT letting people run around with guns really solved Washington DC's and Chicago's violent crime problem, didn't it?
    I doubt it's a fair comparison.
    I'm not sure how they do not let people run around with guns and comply with the 2nd amendment, but in any case you can definitely acquire a gun more easily than you can in the UK.
