What Is Thunderbolt? [What Is]

Source: http://gizmodo.com/#!5769321/what-is-thunderbolt

What Is Thunderbolt?Along with snappy Sandy Bridge processors and beefy GPUs, Apple's new MacBook Pros have a superfast, versatile new I/O tech called Thunderbolt. Whazat?

Thunderbolt is a new standard for connecting peripherals to your computer...

If your laptop is untethered and on your lap right now, it's only there temporarily. Our machines still spend most of the time bound to our desks by myriad peripherals, all of which are connected through various interfaces. Intel's Thunderbolt, formerly known as Light Peak, is a faster, simpler way to plug some of those things in.

...that's works with both PCI Express and DisplayPort devices...

One of the best things about Thunderbolt is that it's dual-protocol, meaning that different types of devices—specifically, those using PCI Express and DisplayPort connections—can work from a single Thunderbolt port. Displays using MiniDisplay port will plug in right off the bat; DVI, HDMI, and VGA displays will work with one of the existing adapters. Thunderbolt has two independent channels, too, so it can supply full bandwidth an initial device and another one daisy-chained down the line.

...and way faster than USB...

To do that, it has to be fast. And it is! Thunderbolt moves at 10 gigabits per second, up to 20 times faster than USB 2.0 and 12 times faster than Firewire 800. Early versions used an optical connection, though the first wave to roll out in consumer products will likely work over copper-based wires. Still, the researchers behind the standard say that transfer rates could be boosted to 100 Gbit/s by the end of the decade.

...that was developed by Intel...

Intel first showed off Light Peak back in September of 2009, zapping a Blu-Ray disc's worth of data in just 30 seconds. Impressive! Since then, they've worked closely with Apple to develop the standard, which brings us to...

...and first implemented by Apple...

Apple's new MacBook Pros are the first to incorporate Thunderbolt.

...with devices coming from LaCie, Western Digital, and more

Intel says a handful of companies are already developing products that will support Thunderbolt, including
Aja, Apogee, Avid, Blackmagic, LaCie, Promise, and Western Digital. They see the new standard appealing to audiovisual professionals, who need to deal with a ton of data with low latency. But Thunderbolt-compatible hard drives will make backing up huge amounts of data hella fast, too.

Cellphones are dangerous / not dangerous: handsets alter brain activity -- scientists don't know what that means

Cellphones are bad, mmkay? Or at least that is what many want us to believe, what with all these warning labels and studies telling us that mobile users will end up with brain cancer and kidney damage. Not to mention the dangers of phone addiction -- horror of horrors -- for our youth. Now, the National Institutes of Health have shown that radiation from your phone's antenna turns you into a supergenius increases brain activity. Using positron emission tomography (PET) scans on 47 individuals with a muted phone on each ear (to prevent aural brain stimulation), the study found a seven percent increase in brain activity in the area closest to the phones' antennas when receiving a call. The catch -- scientists don't know "whether this is detrimental or if it could even be beneficial," so don't go trading your Cell-Mate in for a Bluetooth headset just yet.

iBike Dash turns your iPhone or iPod touch into a cycling computer

Source: http://www.engadget.com/2011/02/23/ibike-dash-turns-your-iphone-or-ipod-touch-into-a-cycling-comput/

There's not exactly any shortage of ways to mount your iPhone or iPod touch to your bike, but there's decidedly fewer options that actually turn your iOS device into a full-fledged cycling computer that's able to replace those from the likes of Garmin. This new iBike Dash device promises to do just that, though. It not only houses your device is a protective, waterproof shell, but it includes an ANT+ speed sensor and is compatible with other ANT+ devices so you can measure heart rate and cadence. It also has room for an extra rechargeable battery to extend your run time, and it naturally makes use of a free app that takes advantage of your iPhone's GPS capabilities (no built-in GPS here to help out iPod touch users). Of course, all that means this one also costs considerably more than a simple bike mount -- look for the basic model to set you back $199, while the deluxe package (including cadence and HR monitors along with an extra battery and charger) runs $329.

Snoop Dogggg goes 4G to celebrate launch of Samsung Galaxy Indulge, was probably paid more than 4Gs to do it

You laugh, but D-O-Quadruple-G does have a certain ring to it. In fact, it sounds a little like the ringing of Samsung's Galaxy Indulge, which is tucked inside the pocket of MetroPCS' CEO right about now. You see, the aforesaid carrier has presumably paid Snoop Dogg (or Snoop Dogggg, as he'll be known until he scurries outside of a 4G coverage area) to change his name in order to celebrate the commercial launch of the world's first LTE Android smartphone. The Froyo-based phone is just barely beating out LG's Revolution and HTC's Thunderbolt, and you can bet that MetroPCS is doing everything it can to let the world know about it. Taking things one step further too far, Snoop's also appearing in a new series dubbed "The G-Connection," and you can peek the first episode just after the brizzle. For rizzle, homedizzle.

Motorola Xoom review

Source: http://www.engadget.com/2011/02/23/motorola-xoom-review/

As we put rubber to road on our Motorola Xoom review, it's important to note that it was only a matter of time before the Android army delivered a proper iPad competitor. Moto's partnership with Google (and use of the 3.0 version of its mobile operating system, Honeycomb), has made that assumed inevitability a very serious reality. There can be little question that the Xoom is certainly a contender for the hearts and minds of potential tablet buyers in the market. Besides boasting that fancy new software (a completely redesigned experience masterminded by the man behind webOS, Matias Duarte), the Xoom is equipped with formidable hardware. The 1GHz, NVIDIA Tegra 2-based slate boasts a sizable 1GB of DDR2 RAM, 32GB of internal storage, a 10.1-inch, 1280 x 800 capacitive display, 3G connectivity (Verizon on our review unit), along with front and rear facing cameras, HD video capability, and loads of wireless options. Not only is the Xoom clearly competitive (and frankly, more stacked) than most of its competition, Motorola has attempted to futureproof the device by offering a free hardware upgrade down the road which will give the tablet access to Big Red's 4G LTE network. Of course, all this power comes with a cost... literally. With a list price off contract of $799, the Xoom is quite a pricey piece of technology to own. Still, with all that's packed inside -- and more importantly with what Google has done on the software side -- the Xoom could represent the next stage of tablet evolution. Is it time to take the plunge? Read on for our definitive answer in the full Engadget review!
