Google Code Search

Google's new code searhc engine rocks! This is gonna be super awesome to dudes like me....
http://www.google.com/codesearch
It not only supports basic search operators, and have added some nifty advanced searching keywords, such as regexp, file:regexp, lang, package:regexp, license...

We can find common web vulnerability very easily (xss, sql injection, remote command execution, remote file inclusion...you name the rest) It must be cool that some one developed a set of signatures like gdhb to match common web application vulnerabilities......Can I do it!
