Engineers tasked with building an airport are faced with countless challenges: The ideal location needs ample space, endless flat ground, favorable winds and great visibility. But spots in the real world are rarely ideal, and engineers are forced to work with what they have, making sure that the end product is the safest possible structure for pilots. A survey of airports around the world turns up a mixed bag, ranging from dangerous and rugged landing strips to mega-size facilities that operate like small cities. Here, PM explores the world's most remarkable airports and why they stand out.
Mental_Floss has a series of cool time-lapse videos.
We’re more than halfway through February, yet spring seems so far off for most of us covered under layers upon layers of snow. Personally, I wish we could just hit the fast forward button to about the the middle April. While time may not work that way, video does. In that regard, tonight’s Late Movies feature a series of time-lapse clips to tide you over until it warms up.

Hey, do you have a Twitter account? Have you ever noticed those messages in which people tell you where they are? Pretty annoying, eh. Well, they’re actually also potentially pretty dangerous. We’re about to tell you why.
The danger is publicly telling people where you are. This is because it leaves one place you’re definitely not… home. So here we are; on one end we’re leaving lights on when we’re going on a holiday, and on the other we’re telling everybody on the internet we’re not home.
The goal of this website is to raise some awareness on this issue and have people think about how they use services like Foursquare, Brightkite, Google Buzz etc. Because all this site is, is a dressed up Twitter search page (link). Everybody can get this information.
Chroma keying is a technique for mixing two images or frames together in which a color (or a small color range) from one image is removed (or made transparent), revealing another image behind it. This technique is also referred to as color keying, colour-separation overlay (CSO; primarily by the BBC[1]), greenscreen, and bluescreen. It is commonly used for weather forecast broadcasts, wherein the presenter appears to be standing in front of a large map, but in the studio it is actually a large blue or green background. The meteorologist stands in front of a bluescreen, and then different weather maps are added on those parts in the image where the color is blue. If the meteorologist himself wears blue clothes, his clothes will become replaced with the background video. This also works for greenscreens, since blue and green are considered the colors least like skin tone.[2] This technique is also used in the entertainment industry, the iconic theatre shots in Mystery Science Theater 3000, for example.
