Warming a Tiny Piece of Mars For Terraforming 205

dptalia writes "It's been a dream of science fiction writers everywhere that we would eventually terraform Mars. Now an engineering student has proposed a way to terraform only a kilometer of Mars. By building an array of space based mirrors to focus the sun's light, a small area of Mars could be warmed to about 68 degrees Fahrenheit (20 degrees Celsius) which would make it easier for explorers to work and live there. Since Mars' atmosphere is thin, the mirrors would have to be carefully designed to prevent them from reflecting harmful radiation as well as light and warmth."

4 Seconds Loading Time Is Maximum For Websurfers 219

nieske writes "Of course we all want webpages to load as fast as possible, but now research has finally shown it: four seconds loading time is the maximum threshold for websurfers. Akamai and JupiterResearch have conducted a study among 1,000 online shoppers and have found, among other results, that one third of respondents have, at one point, left a shopping website because of the overall 'poor experience.' 75% of them do not intend ever to come back to this website again. Online shopper loyalty also increases as loading time of webpages decreases. Will this study finally show developers of shopping websites the importance of the performance of their websites?"
