Hardware Virtualization Slower Than Software? 197

Jim Buzbee writes "Those you keeping up with the latest virtualization techniques being offered by both Intel and AMD will be interested in a new white paper by VMWare that comes to the surprising conclusion that hardware-assisted x86 virtualization oftentimes fails to outperform software-assisted virtualization. My reading of the paper says that this counterintuitive result is often due to the fact that hardware-assisted virtualization relies on expensive traps to catch privileged instructions while software-assisted virtualization uses inexpensive software substitutions. One example given is compilation of a Linux kernel under a virtualized Linux OS. Native wall-clock time: 265 seconds. Software-assisted virtualization: 393 seconds. Hardware-assisted virtualization: 484 seconds. Ouch. It sounds to me like a hybrid approach may be the best answer to the virtualization problem. "

Samsung Develops World's First three-inch VGA LCD 173

Nomad05 writes "Samsung announced this week it has developed the world's first three-inch VGA LCD panel that "directly meets industry interface standards for digital still cameras." What this means is that future LCD screens on digital cameras will allow multimedia to be viewed at a resolution of 640x480. Presently, a majority of camera LCDs only display multimedia at a resolution of 320x240 — significantly lower in quality than Samsung's new LCD. In layman's terms, expect significantly brighter, more detailed LCD displays, which will enable you to review your photography more thoroughly after you take an exposure. This innovation will make it easier to spot blurry images and ensure your photo is framed properly. "

OfficeMax Drops Mail-in Rebates 321

A reader writes "Looks like OfficeMax is dropping mail-in rebates. 'Rebates were the #1 customer complaint we were getting,' said Ryan Vero, OfficeMax's chief merchandising officer. Hopefully other retailers will realize what a good idea this is and follow suit." The best part is that the discount is applied now at the register, so those of us who always thought that the rebates were a scam (or were too lazy to mail in the card) finally get some savings.

Australia Wants to Regulate Internet Streaming 257

Paul writes "After an incident that occurred on a popular television show's internet stream, the Australian government has once again demonstrated that it simply does not understand the internet by indicating that they intend to regulate streaming video. I wonder what these geniuses plan on doing with porn streamed from Europe?"

MacBook Users Fix Trackpad Problem with Origami Paper 291

yonnage writes "Some Apple MacBook owners are plagued with what seems to be a defective trackpad button. The button, when pushed, seems "squishy" and sometimes even unresponsive. While these MacBook owners are getting turned away at the Apple Genius Bars, they have come up with a custom and unique solution to the problem. A piece of paper, placed strategically under the battery pack where the trackpad is located, seems to fix this problem for most users."

Ants Use Pedometers to Find Home 202

Ant writes "New Scientist (a short video clip included) reports that desert ants have an internal pedometer that keeps track of how many steps they take, according to a new study. The insects seem to rely on this system to find their way back to the nest after foraging. Other insects may also possess this pedometer-like system. Some types of ants appear to use visual cues or leave scent trails to find their way home. But desert ants have a remarkable ability to retrace their steps from their nesting site even though they travel on flat terrain that is devoid of landmarks, and any odors quickly fade in the hot temperatures."

Spain Outlaws P2P File-Sharing 432

Section_Ei8ht writes "Spanish Congress has made it a civil offense to download anything via p2p networks, and a criminal offense for ISP's to allow users to file-share, even if the use is fair. There is also to be a tax on all forms of blank media, including flash memory drives. I guess the move towards distributing films legally via BitTorrent is a no go in Spain." Here is our coverage of the tax portion of this law.

Mobile Phones and Lightning a Lethal Mix 374

An anonymous reader writes "In a letter to the British Medical Journal, doctors wrote that people should not use mobile phones outdoors during thunderstorms because of the risk of being struck by lightning. Usually 'when someone is struck by lightning, the high resistance of the skin conducts the flash over the body in what is known as a flashover, but if a metal object, such as a phone, is in contact with the skin it disrupts the flashover and increases the odds of internal injuries and death.'"

The company, most famous on the US market for its Roomba vacuum cleaner, provided '300 PackBot Tactical Mobile Robots deployed in Iraq and Afghanistan to open doors in urban combat, lay fiber-optic cable, defuse bombs and perform other hazardous duties previously done by humans alone.'"

Core Duo Reaches the Desktop 299

rtt writes "AMD has long reigned the desktop CPU market due to Intel's offerings struggling to keep up in terms of performance and power consumption. Yonah is the predecessor to the Core architecture and is predominantly a mobile chip, and is used at the heart of Intel's Viiv technology. Bit-tech has an article about Yonah beating the top of the range desktop AMD chip, the FX60, clock for clock. From the article" 'When Yonah is running at the same clock speed as AMD's Athlon 64 FX-60, we found that it beat it into a corner in just about every situation.'"

Well I'll Be A Monkey's Uncle 648

killproc writes "A new report suggests that interbreeding between humans and chimpanzees happened a lot more recently than was previously thought. The report, published in the most recent issue of the journal Nature, estimates that final break between the human and chimpanzee species did not come until 6.3 million years ago at the earliest, and probably less than 5.4 million years ago."

Novell Delivers Device Driver Breakthrough 241

An anonymous reader writes "Novell today announced a new Linux device driver process to make it easier for third party device driver writers to integrate their drivers with SUSE Linux." From the article: "The new driver process allows customers to obtain drivers independently of Novell® kernel updates and supplies a straightforward approach third parties can use when developing device drivers for Novell's SUSE® Linux Enterprise products. The new Linux driver process developed by Novell allows hardware and software vendors to provide Linux drivers and driver updates for their products to customers directly and transparently, in a way that is completely integrated with SUSE Linux Enterprise delivery and support."
