Google Fiber customers can get speeds as high as 50 times more than that which is currently offered by most cable providers. Typical Broadband Versus Google Fiber ... Typical Internet broadband over an ordinary copper phone line means speeds of a few megabits per second. For services over the same fiber-optic cables as cable TV companies, speeds of 10 to 20 megabits per second are more common. For a numbers comparison, a 10 megabit connection is equal to 1280 kilobytes per second. That said, Google Fiber offers ... (view more)

Flaw Results In Xerox Scanners Making Costly Errors

Xerox has admitted that some of its scanners mix up numbers. It's a problem that could prove costly for business users. Surprisingly, the problem isn't related to optical character recognition, which turns a scanned document into text; instead, the ... mixed-up numbers are right there on the scanned image. David Kriesel, a computer scientist in Germany, discovered the problem when scanning construction documents. The documents Kriesel scanned were related to three rooms of different sizes. However, after making the scan Kriesel found the document showed all three rooms as the same size -- a clear ... (view more)

Roadrunner Supercomputer Switched Off to Save Power

In 2008, IBM's Roadrunner was crowned the fastest computer in the world. Just five years later it's being scrapped. Roadrunner is based at the Los Alamos National Laboratory in New Mexico, where staff work on several projects, including the U.S. ... nuclear weapons program. The computer has some impressive specifications. To put things into context, a new desktop might have the equivalent of two or four processors, perhaps one terabyte (a thousand gigabytes) of hard drive space and four gigabytes of memory. Computer Performance Second-to-None Roadrunner has almost 20,000 different processors. It ... (view more)

'Sentinel' Computer System Helps FBI Solve Crimes

The U.S. Federal Bureau of Investigation (FBI) plans to join the twenty-first century by using computer systems rather than paper to manage its cases. The change may improve detection rates by making it easier to cross-reference data between cases. ... The new computer system, called Sentinel, will also allow FBI agents to make notes on cases via dedicated software. A demonstration for reporters showed that Sentinel contains elements reminiscent of consumer software, such as web browsers, Microsoft Outlook, and tax preparation software.

MIT Launches Online-Only Course

The Massachusetts Institute of Technology (MIT), one of the most respected universities in the world, is planning to launch a course that can be taken entirely over the Internet. It's not enough for a degree in itself, but those who pass will earn a ... certificate. The course will be a prototype for online learning at the university. This is the first time such a high-profile institution has offered a course that yields a passing or failing grade, rather than one where students simply access the information and receive a virtual "attendance" certificate. Existing Course Makes Electronic Leap ... (view more)

IBM Makes Tech Predictions for 2016

Biometric information used for identification is among IBM's five newest forecasts for the year 2016, along with thought-reading smartphones, which is reminiscent of a forecast it made five years ago. Since 2006, IBM has published an annual list of ... five technology trends it expects to take effect within five years. This year's forecasts include the end of passwords, which by 2016 may be replaced by biometric log-ins like fingerprint scanners , iris scanners or even DNA readers. As science fiction as that may seem, it's already in the works: Windows 8 is thought to support an option for log- ... (view more)

Scientists: Table Salt to Increase Storage Density

A tandem of researchers in Singapore claim to have discovered a way to use table salt as a means to increase the density at which bits of data can be stored on a hard disk drive platter. Early projections indicate that this 'salty' method is ... actually 5 times more efficient than current hard disk densities. The method was first introduced by Joel Yang, a scientist at the Institute of Materials Research and Engineering (IMRE) at Singapore's Agency for Science, Technology and Research. Yang was able to hone his method using an extremely high-resolution e-beam lithography -- the same process by ... (view more)

Windows 8 Turns 1 PC Into 5, 10, or 5000

Microsoft has announced that Windows 8 will allow users to create multiple virtual machines on a single computer. It's a feature that's previously only been available on Microsoft's server version of Windows. The tool, which is referred to as ... Microsoft's "Hyper-V," allows users to make virtual copies of PCs -- all within 1 PC (hence, it's "virtualized"). Virtualization, more importantly, addresses major security issues in that it separates the host hardware (your computer) from the operating system (Windows) and the applications which run within Windows. Run 5, 10, 5,000 ... (view more)
