Internet Broadband Through High-altitude Drones

Wed, 22 Oct 2014 04:16:00

mwagner writes: Skynet is coming. But not like in the movie: The future of communications is high-altitude solar-powered drones, flying 13 miles above the ground, running microwave wireless equipment, delivering broadband to the whole planet. The articles predicts this technology will replace satellites, fiber, and copper, and fundamentally change the broadband industry. The author predicts a timescale of roughly 20 years — the same amount of time between Arthur C. Clarke predicting geosynchronous satellites and their reality as a commercial business. "Several important technology milestones need to be reached along the way. The drones that will make up Skynet have a lot more in common with satellites than the flippy-flappy helicopter drone thingies that the popular press is fixated on right now. They're really effing BIG, for one thing. And, like satellites, they go up, and stay up, pretty much indefinitely. For that to happen, we need two things: lighter, higher-capacity wireless gear; and reliable, hyper-efficient solar tech."

Isaac Asimov: How Do People Get New Ideas?

Wed, 22 Oct 2014 02:13:00

HughPickens.com writes: Arthur Obermayer, a friend of the Isaac Asimov, writes that he recently rediscovered an unpublished essay by Asimov written in 1959 while cleaning out some old files. Obermayer says it is "as broadly relevant today as when he wrote it. It describes not only the creative process and the nature of creative people but also the kind of environment that promotes creativity." Here's an excerpt from Asimov's essay, which is well worth reading in its entirety: "A person willing to fly in the face of reason, authority, and common sense must be a person of considerable self-assurance. Since he occurs only rarely, he must seem eccentric (in at least that respect) to the rest of us. A person eccentric in one respect is often eccentric in others. Probably more inhibiting than anything else is a feeling of responsibility. The great ideas of the ages have come from people who weren't paid to have great ideas, but were paid to be teachers or patent clerks or petty officials, or were not paid at all. The great ideas came as side issues."

Fiber Optics In Antarctica Will Monitor Ice Sheet Melting

Wed, 22 Oct 2014 00:06:00

sciencehabit writes: Earth is rapidly being wired with fiber-optic cables — inexpensive, flexible strands of silicon dioxide that have revolutionized telecommunications. They've already crisscrossed the planet's oceans, linking every continent but one: Antarctica. Now, fiber optics has arrived at the continent, but to measure ice sheet temperatures rather than carry telecommunication signals. A team of scientists using an innovative fiber-optic cable–based technology has measured temperature changes within and below the ice over 14 months. This technology, they say, offers a powerful new tool to observe and quantify melting at the base of the West Antarctic Ice Sheet.

Microsoft Introduces Build Cadence Selection With Windows 10

Tue, 21 Oct 2014 23:24:00

jones_supa writes: Microsoft has just released Windows 10 TP build 9860. Along with the new release, Microsoft is introducing an interesting cadence option for how quickly you will receive new builds. The "ring progression" goes from development, to testing, to release. By being in the slow cadence, you will get more stable builds, but they will arrive less often. By choosing the fast option, it allows you to receive the build on the same day that it is released. As a quick stats update, to date Microsoft has received over 250,000 pieces of feedback through the Windows Feedback tool, 25,381 community forum posts, and 641 suggestions in the Windows Suggestion Box.

Ebola Does Not Require an "Ebola Czar," Nor Calling Up the National Guard

Tue, 21 Oct 2014 22:41:00

Lasrick writes: David Ropeik explores risk-perception psychology and Ebola in the U.S. "[O]fficials are up against the inherently emotional and instinctive nature of risk-perception psychology. Pioneering research on this subject by Paul Slovic, Baruch Fischhoff, and others, vast research on human cognition by Daniel Kahneman and colleagues, and research on the brain's fear response by neuroscientists Joseph LeDoux, Elizabeth Phelps, and others, all make abundantly clear that the perception of risk is not simply a matter of the facts, but more a matter of how those facts feel. ... People worry more about risks that are new and unfamiliar. People worry more about risks that cause greater pain and suffering. People worry more about threats against which we feel powerless, like a disease for which there is no vaccine and which has a high fatality rate if you get it. And people worry more about threats the more available they are to their consciousness—that is, the more aware people are of them."
