The demands placed on smartphones by marathon sessions of texting, streaming video, and surfing the Web require that they have blazing-fast processors while, at the same time, be able to disburse the heat these processors generate. A team of engineers is proposing something of a counterintuitive model to designing smartphones in the future--one that has processors alternately powering up and then cooling down, more like sprinters than long-distance runners.

Heat dissipation has become a major limitation to the computational power of processors used in smartphones, where there is no room for a fan or other type of cooling system. Only … Read more

Scientists at IBM say they have made a quantum computing breakthrough that demonstrates that a full-scale quantum computer is not only possible but is within reasonable reach.

In an announcement being made today at the American Physical Society in Boston, Matthias Steffen, manager of IBM's experimental quantum computing group, will unveil the research that has led his team to conclude they are the brink of developing scalable technology that could far outstrip what even the strongest supercomputers can do today.

A traditional bit has only two states--zero and one. But for its quantum computing efforts, IBM has decided to … Read more

During CES 2012, the surprise appearance of OnLive Desktop was an intriguing idea for Windows lovers: rent a Windows 7 computer remotely and stream the whole experience to your iPad.

Helping the cause for the first iteration of OnLive Desktop was its price: free. That version had only 2GB of cloud storage, and the Windows 7 environment ran only a suite of Microsoft Office applications (sans Outlook), but for the cloud-curious and those who lack a word processor for their iPad, OnLive's streaming solution is a clever way to explore a mobile office.

OnLive was slated to release a Pro version with more dedicated servers, 50GB of storage, and access to an assortment of other applications, including a Flash-enabled browser, for $9.99 a month; that's hardly inexpensive, and likely to appeal largely to business executives with expense accounts. Today's launch of OnLive Desktop Plus is a surprise half-step: for $4.99 a month, users get the same 2GB of storage, but added access to that long-promised Flash browser; Microsoft Internet Explorer is included; and users also get Adobe PDF compatibility, and Dropbox support. … Read more

Researchers are getting down to the atomic level in the pursuit of smaller and more powerful computers.

The University of New South Wales in Australia today announced it has made a single-atom transistor using a repeatable method, a development that could lead to computing devices that use these tiny building blocks.

About two years ago, a team of researchers from the Helsinki University of Technology, the University of New South Wales, and the University of Melbourne in Australia announced the creation of a single-atom transistor designed around a single phosphorus atom in silicon.

Now a new paper published in the … Read more

While cloud computing and virtualization have transformed server infrastructure dramatically, it's the rise of solid-state drive/flash technologies that have enabled a storage renaissance.

Flash storage will continue to bring a much needed boost to the enterprise landscape. From Fusion-io's IPO last year to the recent launches of a host of venture-backed startups like Nutanix and Tintri, there's a lot going in the world of flash storage.

As an increasing number of applications and databases are virtualized and deployed to the cloud, traditional disk-based storage arrays are creating serious performance bottlenecks that are rendering them increasingly irrelevant. … Read more

As computers and robots advance, more of the physical world will become "machine readable," whether by a security camera or a robotic car able to process information on the road.

Designer and filmmaker Timo Arnall last week created a video of machine vision footage that helps illustrate the point of view of these machines. The video is a montage of experiments to make machines "see" the human world and create some order around it.

In some scenes, the computer places a colored rectangle around cars and pedestrians to analyze parking-lot traffic or highway congestion. In others, they graphically track the movement of people in city streets, walking through buildings, or waiting in lines.

In a blog post, Arnall said he's captivated simply by the look of the videos, with their colored arrows and boxes superimposed on street corners and roadways. But it's also part of getting familiar with the perspective of robots. "It's something we need to develop understandings and approaches to," he wrote, "as we begin to design, build, and shape the senses of our new artificial companions." … Read more

We've been having a classic-video-game kind of time here at Crave recently, what with our sister site CNET News revisiting one of the old-schoolest of them all--Spacewar--and Crave itself reminiscing about all the quarters we scrounged (and promptly fed to Pac-Man) back in the days of the old arcade.

It's no wonder, then, that we've got an itch to make like Mario, touch us some Super Stars, and stomp us some enemies.

Luckily, it looks like Converse is set to hand us just the footwear for the job. According to blog Highsnobiety, the shoemaker plans to release the pictured sneaks--the Converse One Star Super Mario Bros. OX--this coming March, in Japan (apparently no pricing info is available yet). We're hoping we'll be able to track them down online.… Read more

What started out as a research project at IBM has become not only an unbeatable "Jeopardy" champion but also a new line of business for Big Blue. And it's coming to the cloud.

IBM's Watson project proved a big hit when it appeared as a contestant on "Jeopardy" one year ago and proved that machines are indeed smarter than man (I for one welcome our robot overlords.)

And now, IBM is taking Watson to the next level, having created a commercial business unit working to offer Watson both on-premise and as a hosted cloud … Read more
