New Go integrates with Chrome and Chrome OS. Native, high-speed add-ons and web apps here we come!
A basic definition of 'Native' would be 'closer to the core of your computer'. Add-ons at the moment are executed at a great distance from your computer's processor. This is for security concerns mostly -- if the code is executed in the browser, it can't get at your core files. You're safe. But it's also slow. That's where Native Client steps in.
Google's Native Client software is special in that it runs at much higher speeds than your usual Firefox or Chrome add-ons. It runs much more like another application on your computer, rather than 'a web app' in the browser. It has security built-in that won't allow developers to program dangerous applications.
But it's not actually new. It's been around for months. What is new is that Go, Google's new language, will integrate fully with Native Client!
This means two very important things: a) web apps will be propelled to a new level of speed and complexity when coded in Go with Native Client and b) you are now looking at how applications in Chrome OS will be developed and run.
When you run programs in Chrome OS they will simply be Native Client web applications. There won't be a difference between Photoshop or Gmail, World of Warcraft or FarmVille -- they'll all be tabs in Chrome.
Everything will be a tab in Chrome.
One Google to rule them all. One browser to find them. One tab to bring them all and in the darkness bind them.
