What causes nearsightedness? It doesn't appear to be genetic. Spending lots of time outdoors while growing up seems to greatly reduce the chances of being nearsighted.
- Amit Patel
"Near work, such as reading, had always seemed like an obvious contributor, since short-sightedness appears more common among highly educated people."
- Clare Dibble
"Playing indoor sports turned out to have no benefits for the eyes, whereas even physically inactive time spent outside was beneficial"

"The result? On average the children in Sydney spent nearly 14 hours per week outside, and only 3 per cent developed myopia. In contrast, the children in Singapore spent just 3 hours outside, and 30 per cent developed myopia. Once again, close work had a minimal influence; the Australian children actually spent more time reading and in front of their computers than the Singaporeans...

My optometrist was very impressed that my myopia is getting better. He thinks it's because I take off my glasses to read, but now I think it's because I spent a lot more time outside than others.

How multiplayer competitive games vary based on whether they're skill-based or luck-based, and whether they're played with strangers or with friends.
- Amit Patel
"The most important realization is that typical form of 'fun' that we associate with competitive games is either reduced or turned into a negative experience. Competitive game play with friends becomes less about winning and more about shared experiences. This is a very different emotion. The ability to tell player stories, communicate, discuss and joke with one another are all features...

"The second group are pro-social players who are predisposed to react to competitive situations with a focus on relationship building. In general, they have a lower base level of testosterone. Intriguingly, they do not experience the same misery of failure. In some sense, they aren't playing to win so they don't mind losing. In fact, some studies suggest they even experience increased...

“No pain, no gain applies to happiness, too, according to new research published online in the Journal of Happiness Studies. People who work hard at improving a skill or ability, such as mastering a math problem or learning to drive, may experience stress in the moment, but experience greater happiness on a daily basis and longer term, the study suggests.”

I wanted to use Flash 10's drawTriangles() API but it seems to be slower, and the output quality is worse, than Flash 10's other new graphics API.
- Amit Patel
What's in Flash 10.1? Better error handling, microphone access, GPU acceleration, better video streaming, peer to peer networking, reduced cpu hogging on busy pages (example: not activating Flash until it's visible on screen, shutting down running Flash programs)
- Amit Patel
Reduced cpu hogging! I've been wondering: are flash apps such CPU hogs because they're poorly written, or does flash not provide enough types of events that everyone ends up polling for everything?
- Laurence Gonsalves
Laurence, it is the former, not the latter. Biggest newbie error has to do with not cleaning up after yourself.
- Jason Wehmhoener
I think it's both. I think mostly it's apps that keep polling and timers going for animation and don't turn them off when you're in another tab or whatever. But I also find that even when I have no event handlers or timers, there's still a non-zero cpu consumption, which is rather annoying. I had also read somewhere that because plugins must use the ancient Netscape plug-in API from long long ago, there are some issues that are hard to resolve properly. :(

"At the demonstration non-lethal lasers were used, but they did present a video showing a mosquito bursting into flames and falling to the ground when hit by a laser. Not only can the system target a mosquito, it can also differentiate a male from a female – the females being the only ones that feed on blood and spread disease."

no, it wasn't, but im researching it .....April, well how about "Harnessing blowflies to teach robots how to see" ... http://friendfeed.com/mashabl... :] ... putting flies on flight simulator ... ---- it is INCREDIBLE how any fly can fly - change speed, stop on a dime, so to speak .. it is not possible to recreate such brilliant flight capabilities technically

sorry ..maybe i have changed the story a little bit, it should have been "mosquitos will be used to spread genetically modified malaria, unable to infect, but causing antibodies creation - therefore - vaccination

no problem :] ... here is the link .... http://friendfeed.com/gizmag... ... well , and here may be the REAL story :] - http://news.bbc.co.uk/2... .. i thought they are supposed to bite, but they are actually supposed to take over and create noninfectious kind of mosquitos
- Petr Buben
ok, here is the real now deal - In a daring experiment in Europe, scientists used mosquitoes as flying needles to deliver a "vaccine" of live malaria parasites through their bites. .... http://www.usatoday.com/news... ..... - Malaria kills nearly a million people each year, mostly children under 5 and especially in Africa.

I've had my Air for nearly two years and had heard about these hinge problems. It just happened to me this morning. Bleh.
- Amit Patel
I got the Air the week it came out, and I've had two different sets of hinge problems. A definite case of function attempting to follow form.
- Daniel Dulitz
Well, they say they *are* willing to repair it under warranty. However, *only* if I first have them repair a dent for $250–500. I've had the dent forever and to me it's just cosmetic. So I said no. I'll just live with the hinge problem until the machine dies and then I'll decide what to get next. And I won't get AppleCare.
- Amit Patel
Apple has had hinge problems before the Air. I had an iBook that had a lot of problems with the display cable passing through the hinge, so it would only work when the screen was at a certain angle. I had it repaired under warranty and it happened again. Naturally, this started happening right after I told someone that this computer (my first mac) had given me less trouble than any PC I'd ever owned :)

‘ In fact, unlike Jeanne, Susan is a lifelong sun worshipper. In addition, Susan began smoking in her late teens, and although she stopped for six years in her 20s, she averaged a pack and a half a day for 16 years before quitting in her late 30s. Jeanne never smoked. Over time, it seems, these habits have made a remarkable difference in the way they look. Now, “Susan looks ten years older than I do,” Jeanne acknowledges. ’

Interesting bit: "According to the research analysis, every 10 years of smoking resulted in a perceived extra 2.5 years of age." (Trying to dig up the original study now to see if it actually did prove that.)

“Computer chassis are typically equipped with many case fans, some are designed for exhaust and others for intake. When intake fans’ combined airflow is greater than exhaust, a positive pressure is created inside the chassis. Conversely, when the airflow is greater for exhaust than it is for intake, a negative pressure is created.”

The page has some good diagrams. The positive pressure seems to be better for dust but from what I've read elsewhere it's worse for cooling.

While touring Canada's Banff/Yoho National Parks, we went to Emerald Lake. It's very pretty. It's glacial fed, so the water is silty instead of clear. But the big surprise here was that this is the site of the Burgess Shale! It's an incredible fossil site that led to the discovery of the creatures of the cambrian explosion (500 million years ago), my favorite time period in the evolution of life. The animals were odd — five eyes? spiny legs? This was before the common forms today (like two arms, two legs, one head, two eyes) beat the competing forms. The site is up on the mountain in the distance, and was unfortunately closed when they designated it a heritage site.

Theory is that omega 3 (leaves) is “springtime” food and omega 6 (seeds) is “autumn” food, for storing up fats for winter. We now eat lots of seed/grain based food, so we end up storing too much fat in our bodies. Hm...

"FlashSort sorts n elements in O(n) time. Flash-Sort uses a vector L(k) of length m in a first step for the classification of the elements of array A. Then, in a second step, the resulting counts are accumulated and the L(k) point to the class boundaries. Then the elements are sorted by in situ permutation."

“Today the Google Maps team is rolling out a number of refinements to the look and feel of our maps, the biggest such changes since we first launched about 4.7 years ago. In that time we've been steadily adding details like walkways, address labels, bus stops, new country coverage, and improved satellite imagery, but the look of the map hasn't changed much.”

The book is actually pretty good. It's rather pompous, with the whole "lenses" schtick, the deck of cards, the slowly building "map", and all that. But it's decently written, uses good examples, and generally makes good and broadly applicable points. It's the kind of game design book where you find yourself daydreaming about game ideas instead of reading the book, which I think is a good sign. I'm mostly thinking about non-video games, and it still makes sense.

Jesse Schell was my favorite teacher at CMU. When I went there I didn't even know they had a Game Design course, yet the lessons I learned there have helped my experience design skills more than any other single course. I wish I could take it every year.

Also there's a Kindle version! Though at $44 it's the most expensive Kindle book I'd own. I think I'd spring the extra $10 for the hardcopy.
