  1. Several have retracted? on Statue of Galileo Planned for Vatican · · Score: 1

    The Vatican said that the Pope had been misquoted and since the episode, several of the professors have retracted their protest.
    Let's clarify this sentence a little bit: The Vatican said that the Pope had been misquoted, and the Vatican said that several professors have retracted their protest since the episode. The link reporting this statement is to a press release from the Catholic News Agency, which names only a single professor out of the "several" that retracted. A recent interview on NewScientist (sorry, non-free subscription required) with one of the leaders of the protest suggests a different story, that support for the protest has increased since the event:

    Only 67 of us signed the letter to our rector, however thousands of people are now supporting our initiative by signing online documents. What worried me was the reaction of the Italian media, commentators and even left-wing politicians. Their only argument was: these people are intolerant, they shut the pope's mouth. But the pope is talking continuously. It is we who have problems putting across our arguments. The church operates colleges and university centres all over the world. It owns radio and TV stations, newspapers, magazines.
    This interview also mentions that the Pope's speech was read at the opening ceremony anyway.

  3. Maybe Different, Maybe ?.... on Coping Strategies for Women in IT · · Score: 1

    Maybe, just maybe, the different genders gravitate to the fields that they like. Or, gasp, are suited for. ... Men and women are different, even if the politically correct people don't want you to believe it. So it makes sense that they just might be predisposed to liking different things...including professions.
    Oh, no! I can't possibly take the side of the "politically correct" mafia, so I guess I'll just have agree with you. Good game, sir! Good game!

    But seriously, there are many possible explanations for why different "sexes" (not "genders"). You've got "gender" notions of proper work, explicit sexism, biological suitability, etc. Do you actually believe that the current distribution of the sexes in the workforce is entirely the result of biological predisposition? Maybe you do, and are therefore willing to close the book on this one. That's okay; such premature satisfaction of curiosity has a long, noble history, providing us such excellent rational explanations as Intelligent Design.

    Or perhaps you don't believe this is the full explanation. Maybe sex discrimination, gender norms, conscious and unconscious discouragement, all of these things are responsible for---pulling number out of ass--- 27.324% of the sex distribution in the workplace. Does that sound like a good number to you? If so, we can stop studying the problem, stop seeking reform, and relax to the fact that you've figured it all out with your revolutionary "theory of differing suitabilities". You're knighthood is in the mail...

    Even if you're right---women are inferior mathematicians, sub-par engineers, shoddy historians, pathetic architects---what do you propose? Is theirs an insurmountable handicap, a congenital defect outside of the reach of modern medicine, education and cognitive science? Do we abandon approximately one half of Earth's population to the choice between unemployment or a genetically predestined career? Let me know... my spouse is finishing her PhD and she wants to know what kind of job she should be looking for.
  4. Re:That would BLOW (pardon the pun.) on An Ignition Interlock In Every Car? · · Score: 2, Interesting
    I think the better solution is to actually fuck up people who DUI. Like permanent license revocations. Repeat offenders spend 5 years in a damn sweat shop. You can always have a designated driver.

    Or maybe we could just execute them? But, oh wait, we already know that the death penalty isn't a crime deterrent. What makes you think that threatening to take away their license would work?

    Besides, there is a serious logical problem with allowing a person who has been drinking to decide when he is ready to drive again. And the formulas (e.g., one drink == 1 hour) often fail, due to metabolism, body weight, food consumption, level of tiredness, etc. This would end the problem of "I haven't had anything to drink in 2.8 hours, so I think I'm ready to drive again."

    Of course, an alternative to this law would be to require that all alcohol-serving establishments have a Breathalyzer easily accessible to its patrons.

  11. Re:Vaporware? on 'Reversible' Computers More Energy Efficient · · Score: 5, Informative

    I think you completely misunderstood the article, though in your defense it didn't do a very good job of explaining. The idea is not to be able to reverse logical operations -- that is of little value to anyone. Rather, they're trying to make the electrical changes (the energy transfer) reversible. That's a fundamentally differeent thing.

    Actually, you are wrong, in that the two things are very intimately related. I will assume that, as a chip designer, you are aware of what AND, OR, and NOT gates are, and that NAND is an example of a universal gate. NAND, however, is not reversible; you cannot in general determine the inputs by looking at the output.

    The Fredkin Gate is an example of a reversible gate. As it happens, it is impossible to do reversible computing with two input gates. The Fredkin Gate (a controlled swap; two inputs, two outputs, and a control wire that passes through) has the property that it is

    reversible (Fredkin inverts Fredkin), and

    it has the same number of non-zero outputs as it does non-zero inputs.

    To achieve reversible computing, you need reversible gates. Furthermore, with reversible gates, you can perform any computation with an arbitrarily small amount of energy; the catch is that you need more time (see adiabatic circuits, Carnot engines).

    For those of you who are seriously interested in this topic, I recommend the book "Minds, Machines, and the Multiverse" by Julian Brown.

    Aside from dealing with the above mentioned topics of information (== -log probability), entropy, and reversible computing, it moves on to show the relation of these topics to quantum computing. It even has a good bit of history.

    A very good read.

  14. Re:No difference for a long while, but... on The End of the Oil Age · · Score: 3, Interesting

    The idea is to transition to an infrastructure that does not depend on any particular generation method. This opens the way for your car to be powered by anything-- not just gasoline. Once you can put hydrogen in, you're no longer tied to a single source. As more efficient generators and methods (nuclear, solar, excercise-club treadmills) come into play, your existing car will be able to immediately take advantage of them.

    Correct. But there are other instantaneous advantages also. While converting oil and coal to hydrogen may not be a clean process, it will at least be contained to isolated places (the conversion facilities). We get hydrogen out, which runs our fuel cells with no pollution.

    Contrast this against the current system, where we all get gasoline, and burn it to produce energy. This goes on in every gas-burning automobile (and lawnmower and leafblower and generator and...) to the point that the pollution, while partially controlled, still emits from every one of these devices, spread over the face of the planet.

    Sort of like the Nvidia/ATI co-processor I use to play video games?

    When one reads "scientific computation", one automatically thinks, "not average user". But try reading it as signal processing, i.e. voice recognition. Or image processing, i.e. face/object/target recognition.

    The computers promised to us by decades of sci-fi aren't going to have a single processor. They'll have one for sound synthesis (Sound Blaster), one for image synthesis (ATI/Nvidia), one for voice recognition (special purpose DSP). And then they'll have one on the side, for wimpy stuff like your OS and your web browser.

    it is quite interesting that Dreamworks/PDI movies that closely follow the release of Disney/Pixar ones have similiar basic ideas behind them.

    That might be interesting, if it were true.

    From IMDB.com [imdb.com]:

    The release date for "Antz" was 9-19-1998, two months before "A Bug's Life" on 11-14-1998.

    "Road to El Dorado" release on 3-31-2000, while "The Emporer's New Groove" released on 12-10-2000 (and the only thing they had in common is that they took place on the same continent)

    "Shrek" released on 4-22-2001, six months earlier than "Monsters, Inc" on 10-28-2001.

    The only two Dreamworks movies on your list that actually follow Disney movies are "Sinbad" (following "Treasure Planet") and "Sharkslayer" (following "Nemo"). Seeing as "Treasure Planet" (not a Pixar film, nor was "Emperor's") was a huge failure, as will "Sinbad" be, this Dreamworks copycat theory lacks motive. "Sinbad" is based on the story of Sinbad the Pirate, while "Treasure Planet" is a modernization of "Treasure Island". "Sharkslayer" and "Nemo" both take place under water. I guess you win there.
