  1. Re:Questionable study on Video Games Can Make Us More Creative · · Score: 1

    Of course I haven't RTFA, but I wonder if the test is measuring what the title of the article says it is measuring. Are the results due to playing the video game, or could they be from the physical exercise involved in DDR (considerable). There is probably room for a number of different control groups. Bad science indeed.

    Voluntary physical exertion has already been proven to promote neurogenesis (the creation of new nerve cells in the brain) regardless of the involvement of visual stimulation or problem on the part of a video game. Simply running on a treadmill while staring at a blank wall will produce new neurons, so long as you "want" to do it.

    Interestingly enough, forced physical exertion does not promote neurogenesis.

  2. Re:What about athletes? on Fat People Cause Global Warming, Higher Food Prices · · Score: 1

    It's very true that athletic peoples' bodies burn more calories, but that does not necessarily correlate to their eating more calories than other people.

    Take two people, one who rides a bike two hours a day and one who does not. Two hours on a bike at 15 mph (24.1 kph) burns about 1600 calories. (Don't scoff at this as an implausible amount of exercise, I personally do this.) Your argument would state that the athlete must eat 1600 more calories than the other person. But the non-athlete might eat the same amount of calories as the athlete. They just do not burn it off, resulting in obesity. Why is it that, on average, the people in industrialized countries gain a pound every year starting on their 30th birthday? Because people consume more than they require. Athletes eat the same amount of food as other people, they just burn all of it and simultaneously improve their health. (They tend to eat higher quality food, as well.)

    It is also an outrageous fiction that athletes are a bigger drain on the health care system than the obese. "(Athletes) are a bigger drain on the health care system (than the average person) due to sports related injuries." What statistic you used to deduce that fact?!? Heart disease, high blood pressure, diabetes, and cancer are the top four killers known to medicine. They are also the four most expensive. Every single one is massively exacerbated by the sedentary lifestyle, coupled with overeating (esp. of the wrong foods) that leads to obesity. These are long term, degenerative diseases which cost more money the longer they go on. Heart disease alone costs the United States over $400 billion dollars a year. High blood pressure? Over $60 billion. (Source: CDC) There is no way that sports medicine costs even 1/10th that figure.

    But okay, let's take sports medicine. Obese people put tons of additional pressure on their joints. While there are few detailed analyses of how much obesity contributes to the overall trend, one Canadian study of 17,000 patients found that 9 in 10 who had knee replacements and 7 in 10 who had hip replacements in that country in 2004 were overweight. Sure, an athlete will tear an ACL or require some physical therapy to fix some nagging problem, but it is many orders of magnitude more insignificant than obesity and inactivity in terms of costs and resources.

    Apple's OS X v. Windows XP ads are hardly trolling. It is not trolling when a company compares their product line against their competitor's in a non-subjective way.

    When I pull up the terminal window and type 'uptime' my Mac will return a date figure which is in months (and for a while there in years + months!)

Too often people call out others for flaming simply based on the fact that they don't like what the other party is saying.

    This is not the case with Dvorak. I've been reading him since the late 80s/early 90s. While not being as overtly ridiculous a buffoon as someone like Bill O'Reilly, Dvorak's idea of "fair and balanced" is about as legitimate as that of Fox News. He often chooses which facts to include in a story to give it the slant he wants. He is consitently anti-Apple and makes little attempt to hide the fact. He reminds me of 60-Minutes' Andy Rooney or that idiot on ABC News, John Stossel. (Note: That bit about John Stossel was flaming. The man has the epistemological skills of a turnip and regularly makes an ass of himself on national television.)

The point is that he exists and has the right to voice his opinion, just like when skinheads march or Rupert Murdoch distorts the news. The only way to make people like them go away is to stop listening to them. How many times is a guy like Dvorak going to cry wolf (or inferior product) before people learn to roll their eyes at him?

Nobody would have predicted that most people would now take pictures by holding the camera out in front of them and look at the preview screen to frame a shot.

    Actually, upon examining the history of photography, we see that the twin-lens reflex camera was one of the most prominent consumer camera designs throughout the first half of the 20th century.

    As the name implies, TLR cameras have two lenses, the objective lens for taking the picture and the viewfinder lens whose image is reflected through 45-degrees upwards and projected on a ground glass focusing screen. Since the image projected on the ground glass is viewable on the top of the camera's box body, these cameras were often held at waist height... (the reason why most of your family's photos from the 50s look like they were taken from a child's height!)

    They peaked in the 1950s after the Japanese manufacturers began producing the single lens reflex (SLR) camera. SLRs perform the objective and viewfinder functions through the same lens with the help of a mirror which flips up, producing the characteristic "slap" sound of the SLR.

    At any rate, the design of twin lens reflex camera caused people way back in the 20s, 30s, 40s and 50s to walk around taking pictures in a stiff-armed manner, holding their cameras far away from their faces and peering at a tiny screen. Sound familiar?

The more ecological niches there are in a locale, the more intense the evolutionary pressure to adapt. When species adapt to these circumstances, they often produce organic chemical compounds which are highly complex and completely unique.

  22. Sensors? Pfft... on 8 MegaPixel Digital Sensor Unveiled · · Score: 5, Interesting

    In terms of high-end photography, there are several requirements which rate MUCH higher than simple FPS:

    Input Dynamic Range. This is the range of light values in a scene which the sensor "sees" and is able to record. In order to understand this, think of light at dusk reflecting off wet pavement in the distance. The super bright orange glare hitting your eyes is extremely high intensity light, while the shadowed sides of houses and trees and things are low intensity light. Both of these elements have detail that can be recorded. With a low dynamic range, one or the other can be exposed properly. With a high dynamic range it is possible to capture the detail in very dark shadows and very bright highlights without clipping. (Clipping is truncation to flat black or white pixels with no detail). Chemical film, especially positive film (slide film), has a dynamic range which obliterates the best digital sensors.

    Falloff. This is the ability to clip gracefully. When using any type of transducer, whether it's a microphone, a square of film or a digital sensor, there is a response curve which maps values input values (light/sound) into recordable output values. In the age of analog (vacuum tubes, vinyl records and chemical film) the response curves were all based on Calculus. They literally rolled off (logarithmic) at the ends. This meant that as the microphone, vacuum tube or film overloaded, it did so gracefully with a smooth transition to clipping. In the digital world, our chips are "dumb". They can only do algebra, not calculus. Their falloff is linear. 8-bit = 256 values, 16-bit = 65536 values, etc. Anything above or below this is immediately clipped to white or black, on or off. The digital world is flat, if your input source is flat, you sail right off the edge into infinity.

    Single Pixel Resolution. 99.99% of digital camera sensors use a single layer of matrixed sensors (Bayer array). These sensors are located in gangs of three, similarly to the pixels on an old CRT television. The problem is that each sensor can only see red, green or blue. There is a lot of jibber-jabber that I could go on with, but essentially, bayer sensors really only see 1/3 of the picture information their lenses dump on them. Chemical film is stacked in layers, thus each pixel location "sees" all three RGB. Currently only the Foveon X3 sensor in Sigma digital cameras is capable resolving all the information in each color channel at each individual pixel location.

    Now, even if this new Matrix chip performs at even the sub-par level of today's CCD camera sensors, simply buying a camera with one in it does not by any means guarantee quality photography. Back when the sensor (film!) was interchangable from camera to camera, there was still intense competition between camera and lens manufacturers. This is because the sensor can only "see" the image that the lens and camera body deliver to it. The most important factor is the lens! Imagine rubbing vaseline on your glasses and walking around like that all day. This is life with a cheap camera lens. There's a reason why most professional lenses, without a camera body, cost betweed two and ten times as much as an entire point and shoot camera. If a lens is a valve for light, then a professional lens is like a firehose, a prosumer is like a garden hose, a point and shoot is a drinking straw and a cameraphone is a hypodermic needle.
