The latest experimental utility from Google Research's kitty is Google Tone. The Chrome extension enables users to broadcast and share URLs over audio signals. Google Tone uses your computer's microphone and speakers to exchange URLs with nearby computers connected to the Internet. Any computer, phone or Hangout conversation within earshot that also has the Google Tone extension installed and turned ON can receive a Google Tone notification making sharing url's effortless.

How Google Tone Works?

Tone works on a mechanism that is very much similar to human voice. This Google extension is very aptly named Tone as it has many attributes matching the human voice. For instance, it cannot pass through walls like radio frequencies or require an address or pairing to reach to the receiver. The click of a button produces a chirruping sound from your computer speakers, and this is what sends the URL to other devices that are in the sound hearing range. The chirruping sound is both a dual tone audio (DTMF) and ultra-sonic signal. This has been specially engineered to work reliably even at low volumes in short distances for many different types of audio environment.

Most people don’t realize how vulnerable they are till they get locked out of their PC or have their money stolen. The first response is usually an Anti-Virus, but with 300,000 virus and malware everyday it’s unrealistic to expect that they can catch them all.

Some even do more harm than good as most of these solutions automatically make potentially damaging changes to your PC and are highly dependent to their own ability to detect threats.

How can anyone reasonably protect themselves nowadays? Try this free app I recently discovered called SecureAPlus and read on to get a "Free upgrade" to the Premium version (normally $22.50 per year) exclusively for our readers.

With a phenomenal increase in mobile and tablet users, converged computing is definitely going to be the next big thing in the world of technology. To elaborate, "Phone–PC convergence" means a single app Eco-system and user-interface across mobile, tablet or Desktop computing devices. The technology industry has already prepped the end users for the shift. Ubuntu was without the doubt one of the first major OS name to afloat the idea and even start working on it, with options ranging from Ubuntu Edge, Ubuntu For Cars or the Nexphone concept the idea is now well conceptualized and waiting to became a reality sooner or later, recently Microsoft also joined the race with Windows 10 and started talking about the idea of "Universal Apps" across the Windows devices Eco-system. Microsoft has also taken the first step to make way into the Linux stronghold of "Internet of Things (IoT)" devices with it's "Windows For Devices" initiative and has already started offering free Windows 10 for Raspberry Pi 2.

In a recent presentation Mark Shuttleworth founder of Canonical’s Box (the company to market commercial support for Ubuntu) focused more on the convergence, specifying that currently Ubuntu’s phone application platform can already resize and fit applications to fit the different screen sizes, including smart phones to windows desktop screen sizes.

Here is a peep on how both Windows and Ubuntu are being remodeled around convergence and what are their USP's.

It seems Microsoft has found it's 'nirvana` with Windows 10, the developer announced that Windows 10 will be its last version of operating system at Ignite 2015 conference in Chicago. This announcement surely ruffled some feathers here and there. Everyone around was skeptical as to what strategy is Windows adopting. Some gurus say, its a mere publicity stunt but some tech gurus point out to another pattern, Windows is going to adopt and enact upon.

When the announcement came that Microsoft will not go ahead with any other versions of Windows, people worldwide were amazed and confused. Initially everyone thought for a second that Windows was shutting down but when clarifications came, people started speculating its strategy according to their analyses. Some learned people say that the Windows will keep a pattern similar to Apple's. Apple launched its Mac OS X, 15 years ago and has been updating it since then. Every major update Apple brings for its OS X is named differently, but the basic OS remains the same. This is definitely a better approach to avoid fragmentation in the Windows OS Eco-system which Microsoft's is aiming to converge not only on Desktop but across all devices in future.
