  • Really makes you wonder what type of system actually works – communism failed, dictatorship usually reaches a violent end, and looking at US & India, democracy also has its pitfalls once the politicians game the system.
    “Globalization and going viral have been the catchphrases of the networked 21st century. But until now the former has mainly referred to a fluid worldwide economy managed by important people, and the latter has mostly meant cute-animal videos and songs by nobodies. This year, do-it-yourself democratic politics became globalized, and real live protest went massively viral. But as they’ve rejuvenated and enlarged the idea of democracy, the protesters, and the rest of us, are discovering that democracy is difficult and sometimes a little scary. Because deciding what you don’t want is a lot easier than deciding and implementing what you do want, and once everybody has a say, everybody has a say. No one knows how the revolutions will play out: A bumpy road to stable democracy, as in America two centuries ago? Radicals’ taking over, as in France just after the bliss and very heaven? Or quick counterrevolution, as in France 60 years later? The mostly liberal, secular young people who made the revolutions in Tunisia and Egypt last winter have been subordinated, if not sidelined, by better-disciplined political organizations. And they all agree it’s partly their own fault, a function of naiveté about the realities of democratic politics.”

    “Happiness doesn’t always make you feel happy.”

    • Dan Kindlon, a child psychologist and lecturer at Harvard, warns against what he calls our “discomfort with discomfort” in his book Too Much of a Good Thing: Raising Children of Character in an Indulgent Age. If kids can’t experience painful feelings, Kindlon told me when I called him not long ago, they won’t develop “psychological immunity.”
    • When ego-boosting parents exclaim “Great job!” not just the first time a young child puts on his shoes but every single morning he does this, the child learns to feel that everything he does is special. Likewise, if the kid participates in activities where he gets stickers for “good tries,” he never gets negative feedback on his performance.
    • In fact, rates of narcissism among college students have increased right along with self-esteem.
    • Kids who always have problems solved for them believe that they don’t know how to solve problems. And they’re right—they don’t.
    • parents who protect their kids from accurate feedback teach them that they deserve special treatment
    • The irony is that measures of self-esteem are poor predictors of how content a person will be, especially if the self-esteem comes from constant accommodation and praise rather than earned accomplishment. According to Jean Twenge, research shows that much better predictors of life fulfillment and success are perseverance, resiliency, and reality-testing—qualities that people need so they can navigate the day-to-day.
    • “Research shows that people get more satisfaction from working hard at one thing, and that those who always need to have choices and keep their options open get left behind,” Schwartz told me. “I’m not saying don’t let your kid try out various interests or activities. I’m saying give them choices, but within reason. Most parents tell kids, ‘You can do anything you want, you can quit any time, you can try this other thing if you’re not 100 percent satisfied with the other.’ It’s no wonder they live their lives that way as adults, too.”
    • underlying all this parental angst is the hopeful belief that if we just make the right choices, that if we just do things a certain way, our kids will turn out to be not just happy adults, but adults that make us happy. This is a misguided notion, because while nurture certainly matters, it doesn’t completely trump nature, and different kinds of nurture work for different kinds of kids (which explains why siblings can have very different experiences of their childhoods under the same roof). We can expose our kids to art, but we can’t teach them creativity. We can try to protect them from nasty classmates and bad grades and all kinds of rejection and their own limitations, but eventually they will bump up against these things anyway. In fact, by trying so hard to provide the perfectly happy childhood, we’re just making it harder for our kids to actually grow up. Maybe we parents are the ones who have some growing up to do—and some letting go.

  • Steve Jobs was onto something with the 10″ form factor for tablets, it seems. This study indicates how difficult it is to use regular (desktop versions) websites on a 7″ tablet. Even though the screen is much larger, the user experience is better with the mobile version of a site on a 7″ screen.

  • The user experience is pretty messed up it seems, even after the introduction of Newsstand.
    This also indicates why Android has trouble with user experience (touch responsiveness & smoothness in particular). It all depends on the designer in the end, and iOS is no exception.

  • “The main points are fairly straightforward:
    1) Every lens and every camera exhibits slight variations relative to its twins that are detectable, but rarely significant.
    2) Variations that wouldn’t make the slightest difference in a print may seem quite different when the numbers are presented in a lens review. And, just because one copy of lens X is sharper than one copy of lens Y, doesn’t mean they all are, or that they all will be in your camera.
    3) Occasionally, an acceptable lens mounted to an acceptable camera combine their variations in a way that makes them unacceptable together. The lens may be fine with a different camera, and the camera fine with a different copy of the lens. 
    4) Really bad, soft, out-of-acceptable range lenses do occur. They are fairly rare though and easy to detect.
    5) Camera autofocus is more variable and less accurate than you think.”

  • Quite enlightening, if you ever wondered why many lens reviewers say that they needed to try 4-5 copies of a lens before they got a proper one. Then again, also makes you slightly paranoid about whether your camera body+lens combo works properly. Summary:
    “The mechanical parts that are assembled to form a lens, lens mount, and sensor are going to vary a bit with every lens and every camera.This variation will cause every copy of a lens, and every copy of a camera body, to have slightly different characteristics.A lens may be fine on one camera and not another. A camera may do fine with one lens and not another.Some lenses (and cameras) will be far enough out of spec to just suck, no matter what they are mounted to.It seems logical that ‘bad batches’ can occur because a shipment of one or more parts is defective and not caught during routine testing (or the manufacturer decides it’s cheaper to ‘ship and repair’ than to hold a shipment).When the manufacturer knows about a “bad batch”, they probably identify the problem and correct it for future lenses, but they aren’t going to announce it unless they absolutely have to – when something is so bad it’s affecting overall sales of that item. Roger’s Rule of Problem Announcements: Once its announced that 5% of lens X has a certain problem, 50% of the members of any online forum will announce their lens has the problem. Whether they own lens X or not.Of course future batches aren’t necessarily better, just different. Problem A may have been fixed, but the new supplier of part 32543 may make a bad batch, or the machine tools used to lathe the last set of part 2433 may have become more worn and less accurate.”
