Trying to justify spending money on a MacBook when you could have bought a cheaper Windows laptop? Take a peek at these five handy tips for Mac OS X.
Is an iPad a PC? Depends on who you ask.
It's true the way we use personal technology now is changing, making what we refer to as a "PC" a moving target. Recently, some market share studies have grouped tablets with traditional PCs to show how power in the laptop and desktop market is shifting in favor of, well, Apple, a longtime underdog in the PC world.
PlayStations have seen plenty of army action with games like Call of Duty: Black Ops. Now they're doing real-life military duty as part of the Condor Cluster, a U.S. Air Force supercomputer whose off-the-shelf components include more than 1,700 Sony PS3 processors.
The computer--which will undertake a range of tasks including synthetic aperture radar enhancement, image enhancement, and pattern recognition research--also incorporates 168 separate graphical processing units. It's capable of computing about 500 trillion calculations per second, which makes it some 50,000 times faster than the average laptop.
As such, the Condor can read a whopping 20 pages of information per second. Even when 20 percent to 30 percent of the characters on a page are removed, the computer can recover all of the sentences and words with about 99.9 percent accuracy, according to the official Web site of the U.S. Air Force.
Affordability was a key motivator in the decision to use PS3 processors.
"The total cost of the Condor system was approximately $2 million, which is a cost savings of between 10 and 20 times for the equivalent capability," said Mark Barnell, director of the Air Force Research Laboratory's high-power computing division.
He said the Condor isn't made to compete with the world's largest general-purpose supercomputers, but is meant for highly specific military tasks. "The biggest thing for us was [that] the particular applications and the hardware we chose to build this computer with purposely match those applications well," he said.
Initial projects scheduled for the Department of Defense mega-machine, housed in Rome, N.Y., will include neuromorphic artificial intelligence research, in which programmers will "teach" the computer to read symbols, letters, words, and sentences so it can fill in human gaps and correct human errors. … Read more
The all-black Cr-48 that Google is shipping to the first members of its Chrome OS notebook pilot project looked awfully familiar to us when it showed up at our office.
Software aside, after putting it side by side with a black MacBook that Apple shipped in 2007 we had in house, it dawned on us why: the two are practically twins. Not identical, but at least fraternal. The overall look is shockingly similar to Apple's now-extinct machine: from the color to the chiclet keyboard to the hinge, size, trackpad, even to the indentation in the place where you lift … Read more
Apple today made a move to resolve some display problems that popped up among some of the first buyers of the redesigned MacBook Air.
The Mac maker released a software update for the 11-inch and 13-inch Air meant to resolve a "rare issue where MacBook Air boots or wakes to a black screen or becomes unresponsive."
Some of the early reviewers of the hardware noticed flickering horizontal lines sometimes appearing on the display of the 13-inch model or displays being discolored when waking from sleep. Other early purchasers noted similar issues on Apple support forums. Apple didn't … Read more
Time-lapse videos compress imperceptibly slow events into short videos, seeming to speed up time before your eyes. CNET Editor Antuan Goodwin shows you how they are made and how to shoot one of your own.
SAN FRANCISCO--The Chrome OS hardware Google promised in July of last year is still not ready for prime time. But if you're a developer or an eager early adopter, you're in luck.
At an event today here in the city's Dogpatch neighborhood Google showed us the not-yet-finished hardware that will run Chrome OS. It's called Cr-48, and it's not much to look at: a plain, black, unbranded notebook that companies and individual users who are accepted into Google's pilot program can use.
The actual Chrome OS notebooks that normal people can buy, from Samsung … Read more
Last week, I spent a couple of hours at the Computer History Museum in Mountain View, Calif., which for a small-time collector of tech artifacts is like Charlie getting into the chocolate factory.
The highlight of the visit was a personal tour by Apple co-founder Steve Wozniak, who wandered among the displays and explained how some of the products had influenced his understanding and passion for technology, which culminated in the creation of the first Apple computer. You can see several videos of Wozniak, who was very generous with his time despite nursing a sore throat, here.
My relatively short … Read more
Those IT administrators who felt suckerpunched by Steve Jobs' decision to nix the Xserve seem to be recovering just fine.
There wasn't exactly weeping and gnashing of teeth (at least that we know of), but a lot of loyal Mac users in IT departments were seriously disappointed a few weeks ago when Apple said that as of January 31 the assembly line churning out the Xserve would be permanently halted. There was talk from some of ditching Macs altogether at work in a fit of bitter disappointment, and in light of some anticipated major technical challenges.
With a few … Read more
