Submission + - Why American broadband is slow

Presto Vivace writes: The basic truth about broadband that cable companies want to hide

The American cities that are delivering best-in-the-world speeds at bargain prices are precisely the cities that aren't relying on Verizon, AT&T, Comcast, Time-Warner, etc. to run their infrastructure. In Kansas City, Google built a state-of-the-art fiber optic network largely just to prove a point. In Chattanooga and Lafayette, the government did it. At the moment, the US federal government could issue 5-year bonds at a 1.58 percent interest rate and make grants to cities interested in following Chattanooga and Lafayette down that path. But it doesn't happen, because while broadband incumbents don't want to spend the money it would take to build state-of-the-art fiber networks, they are happy to spend money on lobbying.

Submission + - MIT Trains Robots to Jump (mit.edu)

Nerval's Lobster writes: MIT just announced that its researchers have programmed a robotic cheetah that can leap over obstacles without a prompt from a human controller. The machine’s onboard sensors rely on reflected laser-light to judge obstacles’ distance and height, and use that data to fuel the algorithm for a safe jump. The robot’s controlling algorithm takes into account such factors as the speed needed to launch its mass over the obstacle, the best position for a jump, and the amount of energy required from the onboard electric motor. As of this writing, the robot can clear 90 percent of obstacles on an open track. “A running jump is a truly dynamic behavior,” Sangbae Kim, an assistant professor of mechanical engineering at MIT, is quoted as saying in a university press release. “You have to manage balance and energy, and be able to handle impact after landing. Our robot is specifically designed for those highly dynamic behaviors.” For years, some tech pundits have worried that robots and software will gradually replace human workers in key industries such as manufacturing and IT administration. Now they have something else to fret over: Robots replacing the world’s hurdlers.

Correct me if I'm wrong, but when I take the train I don't drive it and they still put windows on the cars. The passenger area of a commercial airliner also has windows. What would I want to take the windows out of a self-driving car? I like to see where I am and where I'm going even when I'm not in charge of getting myself there.

Of course Facebook is keeping you in a bubble... of exactly the things you chose to put in your bubble. It's no different than any other source of news. Fox News, MSNBC, New York Times, Wall Street Journal, Huffington Post - all bubbles telling one part of one side of the story.

If you don't actively look for other sources of information or other sides points of view, your news sources aren't going to give you "fair and balanced" information.
