“If you were a kid in the 1980s or 90s, you probably spent some time reading, watching, or playing with four adolescent reptilian martial arts experts with irregular DNA. To make sure I got the scoop on everyone’s favorite heroes in a half-shell, I went straight to the source – co-creator Peter Laird – who was kind enough to answer our burning questions about the franchise. If you’re looking for a thorough history of the Teenage Mutant Ninja Turtles, this is a pretty good place to start.” w/ photos

“How on earth would any human being manage to hold his or her breath for these extraordinary periods? And why? Most of us find it difficult to do a length under-water in the average swimming pool. Indeed, the average person can’t hold their breath for more than 30 seconds or so — and even someone in excellent health is gasping by two minutes. Most Japanese pearl divers, who dive deep without oxygen for their treasure, can’t manage more than seven minutes. Such discipline is vital to pearl divers if they want to make a living, but Sietas, a 35-year-old German, risked his life simply to get in the Guinness Book Of Records. So how does anyone go about training themselves to hold their breath for ten minutes and beyond?” w/ photos

“The problems with getting the ‘whole internet’ on your TV have been legion. For one, the fuzzy standard definition TVs in most homes in the late ’90s and early 2000s made content designed for (slightly) higher definition computer monitors displayed on a TV look like you’d rubbed your eyes with sandpaper. But even once you solve the display issue, the more fundamental problem is the interactive model — using a web browser requires a pointing device and text input. You need a way to punch in URLs, site logins, things you want to search for, and a way to select stuff and click on links. From your couch. It’s all about bridging the gap between a 10-foot interface (your TV) and a 2-foot interface (your computer). So the sordid history of internet browsing on your television is partly a timeline of failed interaction experiments.” w/ videos
