Google has announced a new programming language they are calling Go. Think of it as an update to the C language with some bits borrowed from Java, C++, and Python. The compiled language is designed to compile and run very fast. The idea being that the language will be used to build applications that run in Google's Native Client software within the Chrome browser.
What apps need native access to a machines hardware? Well let's see, maybe CAD software, Photoshop type stuff and video games. Since just about all machines are now x86 based, this sort of thing could really make which operating system you run kind of irrelevant. Interesting stuff.
