First Borders, then Best Buy. Now Amazon's gunning for Safeway

SEATTLE -- For the last five years, Amazon has been working to figure out an online business that has claimed its share of carnage -- grocery delivery.

Here in the company's backyard, it's deployed a fleet of green, refrigerated trucks to bring produce, meats, boxes of cereal, and more to customers' front doors 24 hours a day, whenever they choose. And the company has tinkered with pricing formulas, as well as the kind of goods it offers, trying to come up with the right mix that engenders loyalty and still earns a profit.

Lockheed laser weapon hits its mark again

Lockheed Martin's ADAM laser weapon wants to step up its game.

In a series of tests in March and April, the prototype directed-energy system destroyed eight small-caliber rocket targets in flight at a range of approximately 1.5 kilometers (0.9 mile), Lockheed said Wednesday. The defense contractor described the targets as "free-flying Qassam-like rockets," making reference to the simple but deadly projectiles developed by the military arm of the Palestinian group Hamas.

You can see a video of one of those test-firings below.

The 2013 tests follow a series of trials in 2012 when the ADAM (… Read more

Intel's upcoming 'Haswell' chip primed for gaming

Intel wants to make its future "Haswell" chip better than past generations of silicon at gaming and announced tools to make this happen at the Game Developers Conference today.

Forty years ago, the Ohm F speaker was a game-changer; it still is

Lincoln Walsh died a year before his radically innovative speaker technology made its commercial debut in the Ohm Acoustics F in 1972. The speaker featured an omnidirectional Walsh driver that projected a massive stereo soundstage. At the time of its introduction the $900 per pair Ohm F was hailed as one of the greatest speakers of all time by the international press. It sounded like nothing else, and the single 12-inch, truncated cone driver produced bass, midrange and treble frequencies (37Hz to 17kHz). The driver had a titanium top section, aluminum midband and paper bottom, with a single voice-coil at … Read more

How to trick Siri into using Google Maps

Much has been made of the general suckiness of Apple Maps, but, hey, we're stuck with it, right? If you ask Siri for directions, that's gonna be her go-to app.

Google Maps is back on iOS, but this time as a standalone app. You'll find it doesn't look like it did on iOS 5, due to Google having complete freedom with the user interface and design. As such, using Google Maps on iOS is going to feel a bit familiar, yet like a completely new experience.

To install Google Maps on iOS, you'll need to be using an iPhone (3GS and newer), iPod Touch (fourth and fifth gen) or an iPad running at least iOS 5.1. If you're using one of the above devices, download Google Maps for iOS … Read more

Apple's Find My iPhone app gets driving directions

Apple today made a slight new addition to its Find My iPhone software (iTunes), with a tweak that gives owners driving directions right to a lost device.

Under the previous system, users saw only the precise location on a map with the option to refresh. The new update shows your device's location just like a point of interest within Apple's maps software, with the option to fire up driving directions by tapping a car icon.

In practice this means you can now hunt down a device's location without having to guesstimate a location and switch over to … Read more
