Acer unveils C7 Chromebook, portable cloud computing for just $199

Source: http://www.engadget.com/2012/11/12/acer-c7-chromebook/

We found ourselves quite enamored with Samsung's latest entry into the Chromebook line, mostly thanks to its incredibly low price of $250. Now Acer's done gone even lower: $199 for its new C7 Chromebook. It's an 11.6-inch (1,366 x 768) machine with a 320GB HDD and an Intel processor, rated for 3.5 hours of battery life -- just about half that of Samsung's ARM-powered entry. It still manages to be under an inch thick and packs a full-size Ethernet port, plus 802.11a/b/g/n WiFi, three USB 2.0 ports and both HDMI and VGA output. (Cellular connectivity does not appear to be an option.) The C7 is available starting tomorrow at the link below, and while we know many of you still aren't sold on the Chromebook idea, at a buck less than $200 maybe it's time to start pondering more seriously.

Samsung Galaxy Stratosphere II heading to Verizon in the 'coming weeks' for $130

Source: http://www.engadget.com/2012/11/12/samsung-stratosphere-ii/

The Samsung Galaxy Stratosphere II has been officially unveiled as the latest QWERTY device coming to Verizon. We still don't know the exact date of arrival, but Big Red mentioned that it'll be heading to stores and online sometime in the coming weeks. We do, however, know the cost: $130 with two-year agreement and after a $50 mail-in rebate. What about specs? We know that the QWERTY smartphone will offer Android 4.0 (ICS), LTE connectivity, 4-inch Super AMOLED display, NFC and 1.2GHz dual-core CPU. From the sounds of it, we're looking at a pretty mid-range device here -- which ultimately is more evidence that manufacturers and carriers seem to think there's no market for power users who prefer using a physical keyboard. Head below for a brief press release discussing the new handset.

Duke University creates 'perfect' one-directional microwave cloak, might lead to stealthier vehicles

Most attempts at cloaking, no matter the slice of spectrum, usually leave clues as to what's there -- even microwave cloaks can spoil the surprise through reflections. At Duke University, researchers have licked some of those past problems with the first instance of a flawless microwave cloaking scheme. By crafting a special diamond-shaped cloak where the light properties stay consistent at the corners, the school's Nathan Landy and David Smith have successfully shielded a 3-inch wide cylinder from microwave detection without a hint that something was amiss. The gotcha, as hinted by the shape, is a two-dimensional nature that gives away the secret at less than ideal angles. Duke suggests that it still has the groundwork for something that could be vital for communications or radar -- we can imagine a stealth aircraft or ship in the far-flung future that could actively mask itself from radar signals. It's not quite the optical illusion we're looking for, but a refined version of the Duke project might be enough for a rare practical use of cloaking when fantasies are much more common.

Titan supercomputer leads latest Top 500 list, newly-available Xeon Phi chips make strong debut

Source: http://www.engadget.com/2012/11/12/titan-supercomputer-leads-latest-top-500-list-as-newly-available/

The supercomputer formerly known as Jaguar recently got an upgrade that was significant enough to earn it a new moniker, and it turns out that was also enough for it to claim the top stop on the latest Top 500 list of the world's most powerful supercomputers. Now known as Titan, the Cray-developed supercomputer at the Oak Ridge National Laboratory edged out the Lawrence Livermore National Laboratory's Sequoia supercomputer for the number one position, reaching 17.59 Petaflop/s with the aid of almost 300,000 AMD Opteron processors and 261,632 Nvidia K20x graphics chips. As EE Times notes, however, the other big story with this list is the strong showing for Intel's new Xeon Phi co-processors, which have just starting shipping to customers and have already found their way into seven of the supercomputers on the list, including one in the top ten (the Stampede at the Texas Advanced Computing Center at the University of Texas). You can see how your favorite supercomputer did at the link below.

Lamborghini's New $380,000 Aventador Is Topless And Hugely Powerful

Source: http://www.businessinsider.com/lamborghini-reveals-aventador-roadster-2012-11

In the summer of 2011, Lamborghini introduced the Aventador LP 700-4. Having delivered 1,300 so far, the Italian supercar maker is now offering the LP 700-4 as a roadster.

Without a roof in the way, drivers of the new Aventador can enjoy the noise of the 6.5-liter V12 engine that produces a huge 700 horsepower.

The Roadster LP 700-4 comes with a €300,000 ($381,420) price tag, before taxes.

It features Lamborghini's trademark scissor doors.

The roof is made of carbon fiber and weighs only 6kg (about 13 lbs).

It is removed by hand and stored in the front luggage compartment.
