The Great Internet Mersenne Prime Search (GIMPS) project has scored its 14th consecutive victory, discovering the largest prime number so far.

The number, 2 to the power of 57,885,161 minus 1, is a digit that's 17,425,170 digits long. That's big enough that if you want to see the full text, you'll have to brace yourself for a 22.5MB download.

GIMPS, a cooperative project splitting the search across thousands of independent computers, announced the find yesterday after it had been confirmed by other checks. At present, there are 98,980 people and 574 … Read more

The Web browser is the most-used kind of software in the world, having become the de facto way that people access the Internet. Today, virtually all computing tasks can be completed in the browser.

Testing browsers can veer from incredibly complex to shockingly simple, depending on what you're looking for and why. At CNET, we prefer a holistic approach to browser benchmarking, looking at a combination of tests that benchmark general browser behavior, as well as several "real-world" tests that look at browser performance in common scenarios.

Google's newest interactive browser "experiment" transports you from your desk to Oz, highlighting cutting-edge browser tech along the way.

Created in conjunction with Disney and the production company Unit9 to help promote the upcoming movie, "Oz the Great and Powerful," the experiment leverages the latest in Web standards to create a browser-based experiment that previously could have been completed only with Adobe Flash.

In the experiment, called Find Your Way to Oz, you can compose music, goof around with a photo booth, and make a short movie with a zoetrope. If you survive the tornado … Read more

Those who've bought the low-cost Samsung Chromebook will be able to watch Netflix streaming video -- at some point.

"We are collaborating with Google on a solution for ARM-based Chromebooks," said Netflix spokesman Joris Evers last night.

He didn't share details on the company's schedule or its technical approach to bringing its service to Chrome OS, Google's browser-based operating system.

Most Web apps work just fine on the $249 Samsung Chromebook even though it has a Samsung ARM processor rather than the x86 chip found in all other computers running Google's Chrome OS. … Read more

The days of needing an app, add-on, or extension to make video calls in your browser are numbered. Google and Mozilla, the respective makers of Chrome and Firefox, just demonstrated a new development in HTML5's WebRTC protocol that lets people talk to each other using two different browsers and no third-party apps.

Currently only available in Chrome 25 beta and Firefox Nightly, the change in WebRTC comes thanks to the development work of several groups. These include members of the World Wide Web Consortium (W3C) and Internet Engineering Task Force (IETF), as well as engineers at Google and Mozilla. … Read more

New mobile browsers including Google's Chrome, Microsoft's IE, and Amazon's Silk are gaining a foothold in a market that's growing faster than traditional browsing on personal computers.

The mobile browsing market has long been dominated by three products. Apple's Safari has long held the top spot in usage share measurements by Net Applications, with second place going to Google's unbranded Android browser after it surpassed Opera Mini last year.

Safari had 61.0 percent, the Android browser 21.5 percent, and Opera Mini 9.8 percent of usage in January, measurements released today show. … Read more

Microsoft Office 2013 has officially hit the streets, and it offers a significantly upgraded interface, more tools, and perhaps most importantly, a cloud-friendly system that lets you work from anywhere. While CNET's Jason Parker did give the updated Office suite high marks, he was also quick to say that its new $100-per-year subscription scheme will likely be hard for many people to swallow. Sure, there are (confusingly) single-pay standalone versions available as well, but those don't offer quite as much as the Office 365 subscription version.

In any case, if you are part of the camp that is … Read more

For most computer users, the idea of having malware or adware creeping onto your machine has become an accepted fate that comes with being online. More-tech-savvy users can manage to stay clean for a while but, like the flu, everybody gets it eventually. Whether it was through a questionable e-mail sent by a friend or from a moment of weakness when you clicked on that video link promising playful kittens, suddenly you find your beloved computer starting to behave strangely. It might be a quick process; it might not happen right away, but you will know right away something is … Read more

Mozilla Firefox (download for Windows, Mac, Linux, Android, or the Portable App) didn't invent tabbed browsing, but they sure as heck perfected it, or at least the extended network of extensions developers did. If Firefox doesn't include a tabbed-browsing feature you want, there's a good chance you can find one among its numerous add-ons.

Personally, I'm a tab glutton. I might be using a Windows XP box from 2004, but that doesn't stop me from running four Firefox windows with 10-15 tabs open in each. Each window usually relates to a specific task, project, or … Read more
