Google Chrome web browser was released for Windows in Sep 08. Google today has released beta versions of Chrome browser for Linux & Macintosh.

Google today opensourced the Google Chrome OS, billed as “an open source operating system for people who spend most of their time on the web.” The open source project is Chromium OS.

However it looks like Chrome OS’ dependency on the web will cut out most of the developing and the underdeveloped world, which has average to pathetic levels of Internet connectivity.

Finally, after years of wait and speculation, Google has challenged Microsoft on its home turf, the desktop operating system. Google today announced the Chrome operating system. The operating system will initially target netbooks , most of which currently run Windows XP, which is almost 8 years old. Netbooks running Google Chrome OS will be available for consumers in the second half of 2010.

Google has released Sputnik, a suite of 5000 tests that touch all aspects of the JavaScript language as defined in the ECMA-262 standard. It was created to check if V8, Google’s open source JavaScript engine conformed to the spec and to detect unexpected changes in behavior.

Google’s Chrome Web Browser is yet to have the kind of impact that Google manages to get so often with its products. The luke warm response to Chrome was primarily attributed to the fact that Chrome did not dramatically change anything about web browsers.
