Looks like Google is rolling out a new right hand sidebar to provide concise summaries of programming and script-related queries.

As usual, this is being rolled out in phases (or being tested). I’m currently seeing this in Firefox 5 but not Chrome.
Below are some examples for SWFObject, jQuery, noscript and Javascript (click to enlarge).
