doors

When my doorbell goes ding dong and the dogs go crazy, the last thing I want to do (aside from shushing my beasts) is actually talk to the person at the door who I probably didn't even want to talk to in the first place. Unless it's the pizza guy.

Fortunately, a Wi-Fi-enabled doorbell called DoorBot could make the mystery of a random household visitor a thing of the past. The $169 high-tech door device features a built-in camera (with infrared for nighttime support) that captures live video of the person who presses the button. From there, a notification pops up on the owner's device that gives the option to display the video feed on the app (works with iOS and Android tablets and smartphones).… Read more

Refrigerators have always been the hub of the kitchen. Considering that is where all the food lives, it only makes sense. However, there is another aspect of the big appliance that draws constant attention, and that would be the refrigerator door. Sure, the door is where all the fun easy-access items such as condiments reside, but there is another side to the story: the outside.

As a wide-open plain, the outside of the refrigerator door is a perfect area for personalization. Long the center for communication, refrigerators have more recently upped the ante by including Wi-Fi-enabled touch screens (such as … Read more

LAS VEGAS -- A German security researcher says he has uncovered several security holes in routers made by China-based Huawei that are used by many Internet service providers -- vulnerabilities that could allow attackers to take control of the devices and snoop on peoples' traffic.

Huawei routers are mostly used in Asia, Africa and the Middle East. Because they're cheap, though, they're increasingly turning up in other parts of the world, the German researcher -- Felix Lindner, also known as "FX" -- said in an interview with CNET after his Defcon talk on Sunday.

The problem … Read more

The mystery of the magic Microsoft device is finally solved, but what's with all the unanswered questions? In trying to add fuel to the Surface hype machine, Microsoft leaves too much to the industry's collective imagination as we all keep speculating about the tablets' battery life, release dates, prices, and UI experience.

The competition among tablets is still presently in favor of the iPad, so we're hoping that Microsoft has more compelling announcements in the future that integrate some of the company's other inventions.

Jeff and I always fight about which popular musician deserves credit for this generation's aural decay, but the Imperial College in London may have a solution to our problem: let computers compose the music!

A team of researchers believe that digital music can move beyond human creation and evolve autonomously without a real composer. They've developed a learning computer algorithm that continuously creates and combines loops in a random sequence.… Read more

For me a great hi-fi doesn't necessarily have to be the best-sounding one.

It's more about a sound that draws me in. One CD or LP leads to the next, and I don't want to stop to eat, read, go to bed, or watch TV. A great hi-fi is one that lets the music cut loose. Even cheap gear might have what it takes to get my juices flowing. Take the Velodyne vPulse in-ear headphones; they make too much bass and are far from the most refined headphones in my collection, but I keep using them. I … Read more

A good portion of my adolescence was devoted to re-creating "Star Trek" props from household items. I still have my Lego flip communicator.

Now I can save myself a lot of time, effort, and Legos by dropping $30 on ThinkGeek's Star Trek Electronic Door Chime.

A DIY "Star Trek" door can be done. This guy made one. If you don't have the patience for that kind of elaborate project, you can settle for the ThinkGeek door chime's swooshing sound effects instead.… Read more

We've been following the Chevrolet Cruze sedan's evolution from concept to production model. We've even taken a first drive in one. Now, as the 2011 Geneva auto show approaches, we get an early look at the production version of the Cruze's hatchback design.

Interestingly, the five-door Cruze's silhouette and roofline don't change all that much from those of the four-door model when viewed from the front quarter. However, when viewed in profile or from the rear quarter, the Cruze begins to resemble a bow-tie badged Subaru Impreza.

While a Geneva debut signals definite European … Read more

Today, a Ford press release crossed my desk with an interesting tidbit about the sales figures for its new Ford Fiesta. It turns out that the majority of buyers have chosen the five-door hatchback body style over the more conventional four-door model. Apparently, someone at Ford thought this was newsworthy, but for me, it was sort of a no-brainer: the five-door was always the better car in my eyes. But that got me to thinking, "What is it with Americans and hatchbacks?"

We're big fans of hatchbacks here at CNET Car Tech, particularly those of the hot … Read more

The Internet is a killer of art--or at least that's how a couple of former rock 'n' roll gods see it.

John Mellencamp, known for such '80s hits as "Jack and Diane" and "Hurts So Good," last week said the Web is the most dangerous creation since the atomic bomb. Stevie Nicks, the Fleetwood Mac songstress, concluded in an interview this week that the "Internet has destroyed rock."

Jac Holzman, the man who discovered The Doors, founded Elektra Records, and nudged the big recording companies into adopting the compact disc, considers the Web … Read more
