Though YouTube shouldn't exactly be your most trusted source of medical advice, in at least one case, videos on the site can help people manage a common form of vertigo without having to see a doctor, according to researchers from the American Academy of Neurology.

However, as is the case with pretty much any aggregator on the Internet (think Wikipedia), one should proceed with a healthy dose of caution, because just over half the videos are accurate -- which means, of course, that the others aren't.

The researchers who reviewed YouTube videos of the Epley maneuver, which can … Read more

The iPhone and iPad are truly elegant designs, but they are the rare exceptions in the rather drab world of consumer electronics. Most cameras, printers, computers, home theater receivers, and speakers are pretty sedate, but there is one product category that stands out: turntables. I've picked a choice selection that represents remarkable achievements in industrial design, and they're highly functional, exquisitely engineered products.

The Redpoint Model A turntable has an aluminum and composite Teflon platter, damped by silicone oil, and the turntable features a battery-powered 12-volt DC motor with precious metal brushes. The turntable weighs 90 pounds.… Read more

For years, analysts have debated whether tablets will eventually replace laptops. Turns out that consumers largely believe they will--and the elderly are far more convinced of that fact than whippersnappers.

Polling company Poll Position, which surveyed 1,155 registered American voters last week, found that 46 percent of respondents believe tablets will eventually replace laptops. About 35 percent of those folks say that devices like Apple's iPad or the Amazon Kindle Fire won't replace notebooks. Nearly 20 percent of respondents had no opinion on the matter.

Although it's generally believed young people will drive the adoption of … Read more

More good news for Silverlight it seems, as based on two new job postings on Microsoft's site (1, 2), the company is looking to hire additional Silverlight engineers, as well as bring the technology to more of its devices--including the Xbox.

Blog TechTrends discovered and reposted the positions earlier today, before Microsoft removed the reference to the Xbox, which was referred to as "Silverlight on the Xbox as part of the next wave." The posting has since been changed to refer to "various devices we plan to enable over the coming years."

The news comes … Read more

Ten years ago today, President Bill Clinton gave the green light to the U.S. military to stop intentionally scrambling satellite signals, thus paving the way for civilians to use GPS with the same accuracy as the military had long enjoyed.

A decade later, mobile navigation is an indispensable part of many people's everyday lives, both in the U.S and around the globe. GPS receiver prices have dropped sharply, costing a few hundred dollars or less where they used to cost thousands. Devices have also gotten more compact and feature-rich, now routinely including access to real-time information from the Internet during route calculation--the latest traffic reports, online points of interest, and so on.

Clinton's order, which kicked into gear at 8 p.m. EDT on May 1, 2000, effectively increased the pinpoint accuracy of any consumer-grade satellite navigation receivers from around 100 yards to just 10 yards.

"President Clinton's landmark decision to open up the GPS signal in 2000 was the catalyst that triggered the launch of navigation systems as we know them today," said Johannes Angenvoort, executive vice president of Navigon, the developer of MobileNavigator for the iPhone and other smartphones, which is arguably the most comprehensive application of its kind.

A history of satellite navigation Apart from cars, boat, airplanes and so on, satellite navigation technology is now standard in mobile phones and handheld devices, but the satellite positioning signal has been available to the U.S. military since 1960. Then, the first navigation satellite, the Transit 1B, launched into space and marked the beginning of the U.S. Navy Navigation Satellite System. This system was developed primarily to guide Navy military missiles.

This pioneering project led the U.S. Department of Defense to improve accuracy with a follow-up system, which launched in the 1980s, called the Global Positioning System (GPS) that is still in use for positioning today.

When GPS service was first made available for civilians in 1983, for national security reasons, the U.S. military decided to scramble the signal, making it a little too inaccurate to be reliable. This practice, also known as "selective availability," was aimed at preventing military use of GPS by the enemies.

President Clinton's decision to turn off the GPS interference signal in an effort to make the GPS more responsive to civil and commercial uses helped consumer-grade mobile satellite navigation finally make its breakthrough.… Read more
