If your GPS told you to jump off a bridge, would you?

That's exactly what happened the first time I went geocaching. After throwing some coordinates in a GPS, we were off to a great start. The GPS led us to a bridge and said that we had reached our destination while crossing it. That meant that the geocache couldn't be too far from the bridge. We began searching around it, looking up in the trees and shuffling through the tall grass with our hands.

Let me begin by telling you all straight out, I realize I'm whining. I know this is pathetic and petty and I'm supposed to have a shred of journalistic integrity or something. I figure, if I can't whine in my own column, than what's the point? So if you're not in the mood for a rant, just 'peace out' sister brother mother friend. Go with my blessing because I've had a doozy of a day, and I'm about to unload.

Earlier this week I had an appointment to see my lady doctor. Thinking of myself like a family sedan, I decided that regularly scheduled tune-ups could go a long way to increase my longevity. It was a lovely thought. Unfortunately, when I arrived for my check-up, the secretary informed me she had been trying to reach me all day: 'Your physician called in sick.'

In our constantly-on-the-go society, smartphones and tablets make it easy to navigate through even the busiest days. If you tend to get lost, travel often or strive to be more efficient, rely on your mobile device as a navigation tool. Whether you're embarking on a road trip, driving to your kids' away games, meeting clients in an unfamiliar area or going on a hike, new 4G LTE mobile devices, such as the Samsung Galaxy S Aviator or Samsung Galaxy S Tab 10.1, and the latest GPS technologies will get you there successfully.

Today's smartphones, tablets and GPS technologies are more sophisticated and user-friendly than ever before. Helpful new features include embedded GPS receivers and mapping services, providing real-time position tracking and voice-guided or text directions.

BERKELEY, Calif. - Sharp-eyed dog walkers along the San Francisco Bay waterfront may have spotted a strange-looking plane zipping overhead recently that that looked strikingly like the U.S. stealth drone captured by Iran in December.

A few key differences: The flying wing seen over Berkeley is a fraction of the size of the CIA's waylaid aircraft. And it's made of plastic foam. But in some ways it's just like a real spy plane.

The 4 1/2-foot-wide aircraft, built by software engineers Mark Harrison and Andreas Oesterer in their spare time, can fly itself to specified GPS coordinates and altitudes without any help from a pilot on the ground. A tiny video camera mounted on the front can send a live video feed to a set of goggles for the drone's view of the world below.

'It's just like flying without all the trouble of having to be up in the air,' Harrison said.
