Shellshock bug testing for vulnerability

There's a new bug that has been discovered recently, requiring affecting most linux systems running bash. You can read more about it here, but the question most often asked is: how to check if you are vulnerable? Here's a simple way to find out. Login to your Linux box and run the following:

env x='() { :;}; echo vulnerable' bash -c "echo this is a test"

The output will be, if you are not vulnerable:

bash: warning: x: ignoring function definition attempt
bash: error importing function definition for `x'
this is a test

If you are vulnerable:

vulnerable
this is a test

Update (Oct 2): Here's a newer version of the test script. It incorporates tests for all of the other bugs related to shellshock

Test results are self explanatory:

If not vulnerable (will appear in a healthy-green colour):

Not vulnerable to CVE-2014-6271 (original shellshock)
Not vulnerable to CVE-2014-7169 (taviso bug)
Not vulnerable to CVE-2014-7186 (redir_stack bug)
Test for CVE-2014-7187 not reliable without address sanitizer
Variable function parser inactive, likely safe from unknown parser bugs

If vulnerable:

Variable function parser active, maybe vulnerable to unknown parser bugs
Vulnerable to CVE-2014-6271 (original shellshock)
Vulnerable to CVE-2014-7169 (taviso bug)
Vulnerable to CVE-2014-7186 (redir_stack bug)
Test for CVE-2014-7187 not reliable without address sanitizer

Windows 9 gets features from Ubuntu and Windows Phone

You've asked for it and Microsoft heard you loud and clear:

"In the version of Windows 9 demoed in the leaked video, the Metro style Start screen has been replaced with a traditional Windows desktop, complete with the taskbar at the bottom with frequently used app shortcuts. One new element that wasn’t in prior leaked screenshots is the search icon. It appears on the taskbar, next to the Start button. On the right side of the search icon is, at long last, the Virtual Desktop icon. Virtual desktops, a feature that allows users to create, save, and easily switch between multiple desktop configurations, has been available in competing operating systems, like Ubuntu, for some time. With it, a user could have a desktop with several image and video editing applications open and running, and then switch to a different desktop used for browsing the web, or one with a running game, waiting to resume progress. It’s a useful way to manage system resources, as well as screen real estate."
