The speed of light is the universal speed limit, so naturally, optical technologies appeal when trying to construct speedy computational devices. Fiber optics let us shoot data to and fro at top speed, but for the time being our CPUs still make their calculations using electronic transistors .

Researchers build optical transistor out of silicon, provide path to all-optical computing

Maingear gave us a quick nudge to say something was coming. Now it can reveal that — alongside Intel’s third-generation processors inside all of its desktops and laptops — it’s further updated two of its tower models. The F131 ($1,049), the middleweight option, now houses the same vertical heat-dissipating design found on Maingear’s Shift model, alongside hot-swappable storage
The Logitech Ultrathin Keyboard Cover: covers the front, but you’ll need a back shield. (Credit: Sarah Tew) (Updated April 26, 2012 with two new keyboard cases.) The one differentiating feature separating the iPad from portable computers such as Netbooks for many people, other than the OS, is a keyboard
Google’s changing its search algorithm to punish sites that emphasize search-engine optimization over quality. Mountain View’s data centers will exclude sites that offer no useful content, have articles written in keyword-sprinkled gibberish or only link to sites within a cluster. If the computers find it, the site’s pagerank will be demoted, with the company expecting to affect around three percent of all English language queries when it goes live later this week.
Welcome to Growing Up Geek , an ongoing feature where we take a look back at our youth and tell stories of growing up to be the nerds that we are. Today, we have our new reviews editor, Sarah Silbert
A prototype of WristQue, a wearable sensor for connecting to smart building controls. (Credit: Martin LaMonica/CNET) CAMBRIDGE, Mass.–An MIT Media Lab project called WristQue offers a way to interact with smart buildings and computers in an unobtrusive way. Researchers at the Media Lab recently completed the first prototype of WristQue wearable sensor and described some of its potential uses yesterday here
Let’s face the fact that tablets and smartphones these days tend to hog the headlines when it comes to computing devices, and computers are not all that hot anymore. This does not mean that nobody is buying desktops, notebooks and workstations any longer, but rather, the more interesting bits of news and rumors all hail from the smartphone and tablet departments.
Bill Buxton has spent most of his career getting between humans and computers. While his initial focus was on music and digital instruments, that eventually led to an interest in human-computer interaction, and pioneering work with multitouch systems and other user interfaces.
Recently, Microsoft rolled out Skype for Windows Phone Beta at Mobile World Congress which happened this February at Barcelona, Spain, and we are proud to bring you word that the app itself will now be available in the Windows Phone Marketplace – not the Beta version, mind you, but the full blown app that has dropped the “Beta” tag, where it is now simply known as Skype for Windows Phone.
