  1. Re:Was it just [re]discovered, that simulations... on Scientists Step Down After CRU Hack Fallout · · Score: 1

    One renown scientist told me that simulations are just models that you tweak to get results you want.

    In a very narrow interpretation, this is correct. If you're playing the good scientist for the day, you tweak a model to get results which agree with known values, which are the results you want. Then, using the refined model, you simulate the situation you want to predict. When those numbers come out, you tweak your model to find out how sensitive the simulated results are to each of the simulation parameters to estimate error bounds. Lather, rinse, repeat, publish.

    Many scientists (I am among them) toss around glib quotes that serve more as cautionary tales, but the non-science public gets to hear these out of context and thinks of them as evidence of fraud. As an example which applies to simulation, in physics: "Theorists don't believe each other, experimentalists don't believe their results and computational physicists don't believe themselves." Which is really to say that computational physicists are always on the hunt for artifacts (read: wrong answers) due to the simulation process; these are distinct from incorrect theories.

    Before you conclude the innocence or guilt of the CRU folk from something you heard from some other person who wasn't even commenting on their situation, let the investigation look at all the data.

  2. Re:No Denial Here But What Are the Reasons? on FOSS Sexism Claims Met With Ire and Denial · · Score: 1

    If there's any sexism, I've seen no proof it's internal to FOSS.

    Are you raising the subject of sexism just based on the fact that only 1.5% of FOSS developers are women?

    Yes, as opposed to 28% in proprietary software (http://www.openwebvancouver.ca/sites/default/files/byron-women_in_open_source.pdf, p. 14-17). If it were as simple as "this trait [of willingness to do significant unpaid work] is far less common in women than men," then you'd expect that no volunteer organization to have a significant population of female members. But peace corps volunteers are 60% female (http://www.peacecorps.gov/wws/enewsletter/archives/may09.html).

    I'm inclined to agree with you that women are not attracted to programming in general because of social factors external to the programming world, but there are definitely internal factors as well. (As evidence, I cite the fact of active research in the field of physics education toward understanding why women initially do well in introductory courses, but progressively drop off in higher-level courses. Mind you, this research is done by real physicists.) Most technical fields suffer from this. Non-commercial programming doesn't require a different level of competence than commercial programming; free software approaches problems of similar difficulty and scale as non-free software, therefore a difference between men and women (if one exists!) in interest or competence doesn't account for the large difference in female participation. I'd bet money that there are numerous causes which the FOSS community will need lots of time to sort out and repair, but they're not all invisible.

    Bruce Byfield touches on part of the problem (http://itmanagement.earthweb.com/osrc/article.php/12068_3838186_2/Sexism-Open-Source-Softwares-Dirty-Little-Secret.htm): When an incident occurs where a joke unintentionally offends, the person who made the joke inevitably says something to the effect of "it was just a joke, chill out." This only serves to alienate women (and other offended groups), rather than re-gain their confidence. This applies in the cases of all mistakes, particularly on the part of leadership, which affect others. A failure to acknowledge the error will only persuade people to leave the community.

    Defending the mistake is the wrong thing to do, and will only make the offended people more angry because most human beings do not like having their feelings and opinions ignored (I offer a lifetime warranty on this technique for alienating people). The excuse, "it was just a joke," essentially invalidates the opinion of the offended people, whether or not the defendant intends (you might notice that people who make excuses excessively have few to no friends). The correct thing to do is actually apologize. To understand this process the apologetic party must make an attempt to stand in the other party's shoes, then coherently address their concerns. To effectively show concern for the complainant, the person apologizing must be brave about it and never mount a defense. The process follows:

    1) Do NOT defend actions. Do NOT put the burden on the other party; specifically, use active first person verbs ("I made...", "I will...", etc.), and do not use the passive voice ("I was misunderstood...") as it contains an implicit "by [someone]," effectively deflecting responsibility.

    2) Acknowledge the other person's feelings. (Examples: Formal; "I understand that you are uncomfortable with something I [said/did]." Less Formal; "I get that you're pissed at me.")

    3) Acknowledge responsibility. (Formal; "This arose from [an action I took/a statement I made]." Less Formal; "I messed up.")

    4) Cite specific failure. (Formal; "I did not foresee the [negative outcome(s)/implicit message(s)] which I [caused/expounded]." Less formal; "I didn't know [it] was meaningful to you.")

    5a) If a lesson was learned state the lesson. (Formal; "In the future I will be more aware of the impact my [w

    I am tired of Mr. Thompson's flawed argument that anyone effectively "trained" on any violent video game anywhere. Firing a rifle/pistol/whatever in a video game is nothing like firing its real-life equivalent. For starters, breathing comes into play, as well as the weight of the weapon and the motion of the trigger finger. A video game controller allows you to separate all these things from the motion of the crosshairs. Your thumb and pinky move separately rather nicely, the controller itself is fairly light weight, and when you breathe, the joystick doesn't move. Nobody can train for firing a real, live gun by shooting at elites and grunts with illuminated pixels!

  5. What kind of tripe is this? on Astronomers Again Baffled by Solar Observations · · Score: 1
    From this page, from the site in the third link: http://thunderbolts.info/webnews/ghosts_of_dark_ma tter.htm

    The low brightness of supernovae in highly redshifted galaxies is easy to explain, based upon Halton Arp's linking of high redshift and faintness of a galaxy to the youthfulness of a nearby galaxy. In an electric universe, a galactic circuit powers supernovae. In a new galaxy the driving potential is low, causing both the observed faintness and high intrinsic redshift. A supernova in such a galaxy will therefore have reduced power and brightness.
    (Emphasis my own.) What the hell does a low "driving potential" have to do with redshift? Last I checked, applying an E field does not alter the color of propagating EM radiation. What the hell are the editors thinking? I understand the need for a diversity of ideas, but at least try to present ones which are well-founded.

  8. linear vs. non-linear on Debunking a Bogus Encryption Statement? · · Score: 1

    I'm a casual observer in this field, so someone correct me if need be.

    Typically, with encryption, the time required to brute-force attack is exponential to the number of bits. So:

    let n = the number of bits in the encryption key

    let t = time required to crack said encryption

    and a = an arbitrary constant

    typically t is proportional to 2^n.

    So, when you encrypt with a 128-bit key, t = a * 2^128

    But if you use a 64-bit key twice, then t = 2a * 2^64 = a * 2^65 since all you have to do is crack a 64-bit key, then crack another.

    As you can see, using two passes with a 64-bit key is 2^63 times worse than just using a 128-bit key once.

While the X-Prize is nice, the fact of the matter is that the majority of space launches are unmanned and I think the X-Prize goal of getting two men into space and back safely is very nice indeed (afterall, we need manned launches, too), but slightly misguided. Maybe it should be for an unmanned craft of some kind that can put something into orbit and then two weeks later retrieve it.

    Or what about the shipping department? Overseas shipping is amazingly expensive. If stuff could be sent by way of self-guided cruise missile, it'd be cheaper to ship and a hell of a lot faster.

    I may be a little naive to think that stuff could be shipped overseas by way of missile, but unmanned orbital placement is far more profitable than X-Prize-type stuff and will be used far more often as a result.

Are fuel economy issues just FUD from [insert lobby group of choice]? Or is the answer simply 'it depends on how you drive, what you had for breakfast, and the color of your neighbors' cat?'"
    No, you're not a rare breed. There are a few things that affect gas mileage and to different degrees. Here they are in the order of greatest degree of effect to least as I've observed.

    1) Engine displacement

    Larger engines draw more air/fuel mixture into the cylinders, then burn it.

    2) Number of cylinders

    In an internal combustion engine, the cylinders are constantly accelerating, therefore, more cylinders = more energy consumption just to keep the engine going.

    3) Vehicle weight

    Heavier vehicles take more energy to accelerate and increase the amount of friction in the wheel bearings.

    4) Aerodynamics

    Vehicles that are less aerodynamic lose more energy to wind resistance. Opening a window affects wind resistance, too.

    5) Transmission

    If your transmission is better matched to the speeds at which you commonly drive and the range of rotational speeds at which the engine runs most efficiently, you get better gas mileage.

    6) Engine care

    If you keep your oil pan full and change it often enough, your engine will continue to run nicely for a very long time. Wear produces small leaks over time, which affect gas mileage by sapping power and causing incomplete combustion in the cylinders.

    7) Intake system

    A friend of mine switched to a high-flow air filter and gained 3 miles per U.S. gallon. This is because the engine doesn't have to work as hard to take air in to the cylinders as a result of higher flow rates. A higher possible flow rate results in less vacuum at a given engine speed. Also, carburetion vs. fuel injection makes a difference. While a well-tuned carburetor is just as good as fuel injection, carburetors are subject to gasoline loss due to evaporation.

    8) Exhaust system

    The engine also has to push exhaust gases out. A less restricted exhaust system makes that require less work. I've heard of improvements ranging from 0 to 5 miles per gallon as a result of switching from a stock muffler to an irritating glass pack muffler.

    9) Driving style

    If you drive faster, it takes extra energy to get to gain those precious miles per hour. If you regularly run the engine to the red line, you consume gas much more quickly than someone who keeps it in that range of max efficieny most of the time. If you run your air conditioner, the compressor for the refrigerant consumes a significant amount of gas. (The heater doesn't, though, since it runs off the same system as the radiator, which works all the time that the engine is running.) If you have a gazillion watt stereo system, it consumes energy through your car's alternator. If you don't believe me on that one, look in a physics textbook. Oh yes, and my favorite, if you drive with one foot on the brake pedal at all times, you'll sap energy and wear your brake pads down.
