In OS X the first user is by default an administrator account so administrative functions can be run, and adding new administrators is usually as easy as authenticating and checking the appropriate box for the respective user in the Accounts system preferences. We were recently contacted by a reader who found that her system was no longer able to create new administrator accounts and all the previous administrators were now listed as standard users, leaving the root account as the only way to administer the system.… Read more
Late last year I told you about CNET's new tool to accurately rate wireless coverage across the United States. With our partner Root Wireless, we're able to show average signal strength, data throughput, dropped calls, and failed data connections for the four major carriers (AT&T, Sprint, T-Mobile, and Verizon Wireless) in great detail, even down to a city block.
Though we've received positive reader feedback about the service since its launch, we also know that you've wanted more coverage (no pun intended) beyond the current 16 metro areas. Well, the good news is that … Read more
Root Wireless, a company that offers a performance-mapping service of cell phone carriers, took the opportunity to test the wireless data performance of all four nationwide carriers at Sun Life Stadium during Sunday's big game. The results, according to Root Wireless, seem to show that T-Mobile came out on top, while Verizon came out at the bottom of the pack.
T-Mobile saw the fewest connection failures (3 percent), while Sprint came in close behind (9 percent). Both carriers had data speeds on par with their everyday service levels--T-Mobile's was 237Kbps down/126Kbps up, while Sprint's was 231Kbps … Read more
When they're not asking about the best cell phone for their needs, CNET readers are inquiring about which carrier has the best coverage in their area. It's a great question, and a very relevant one, but answering it always has been tricky. Because CNET doesn't have the resources to accurately test wireless coverage across the United States, I've suggested that readers ask their neighbors to share their carrier experiences. While that is good advice--personal stories can be very helpful in making a decision--we couldn't offer hard data. That is, until now.
Over the past year CNET has been hard at work creating a better solution. In doing so, we've teamed with Root Wireless to create a powerful tool for determining the best carrier for your neighborhood, commute, or workplace. Next time when you're shopping for a new mobile phone or considering switching to a new carrier, we hope we can help.… Read more
Maurice Tuff, an electrical engineer from Newfoundland, is the brainpower behind a technology that will deter teenagers from reckless driving. Root Four Imagination, Inc. will be showcasing the Safe Driving Monitor, a device that monitors a driver's speed, distance traveled, and braking habits.
The company recently received $25,000 from the Provincial Government of Canada to better their marketing through an e-commerce enabled website, promotional materials, and possibly attending CES 2010.
Safe Driving monitor consists of two simple parts: a sensor that plugs into the car's diagnostic port (easily accessed underneath the steering wheel), and a keychain sensor … Read more
If your iPhone was recently "Rickrolled" by a worm that targets jailbroken iPhones, the following six steps will show you how to change the root password--used to connect to your device via a Unix software secure shell--to protect yourself in the future.

Thanks to the hard work of Kent German, Bonnie Cha, and Nicole Lee, CNET's reviews of mobile handsets are unparalleled: we are the place on the Web to get in-depth evaluations of nearly every handset offered by the major carriers.
But we're not satisfied because we know you're not.
Judging a phone by its features, design, and quality is just half the story when determining whether it is worth purchasing. The other half of the equation is the quality of service provided by the carrier--and that's a factor we have not yet provided. After failing to … Read more
RootsMagic provides a set of tools for designing a family tree. With simple directions and an excellent layout, family roots can be monitored from their earliest origins.
The program's interface had us hooked from the get-go. Its simple family tree display and easily entered info meant we never needed to consult the program's instructional Help file. While we were expected to do the research ourselves, the program provided a simple bracket system for mapping out our family's history. We were prompted to enter birth and death dates, photos, hometowns and other important information, which formed a web … Read more
By default, the root user is not enabled in Mac OS X 10.6 Snow Leopard. Enabling it takes a simple procedure by way of the Directory Utility application or via Terminal. In Mac OS X 10.5, Directory Utility was located in the Applications > Utilities folder. In Snow Leopard, this is no longer the case. You can now find Directory Utility in System > Library > CoreServices.… Read more
Home schoolers, high school tutors, and students needing additional mathematics study will find this many-featured app a handy addition to their toolbox. It provides assistance for grasping two-dimensional function graphs with animation, analyzing functions, understanding analytic geometry, solid geometry, and more.
Math Studio launches a three-paned interface similar to the familiar e-mail client design: the upper-left vertical pane is a graph manager, the lower-left pane is a result editor, and the large pane on the right is a plotting area for displaying graphs. However, the cluster of icons in the three toolbars aligned along the interface's top may intimidate … Read more
