A few weeks ago Google launched Google Code Search which allows you to search through source code that Google finds while crawling the Web. Like Google Scholar, this promises to be a really useful tool for searching specifically for resources that you want while ignoring all the other garbage that’s out there. It's also another small step into pulling the deep web up to the surface.
Of course this also opens the door to embarrassing numerous programmers and organizations and exposing many security holes by allowing you to search for code vulnerabilities, usernames/passwords, backdoor passwords, etc. Google has acknowledged these potential problems but maintains that all tools can be used for good or bad purposes and that the good far outweighs the bad in this case. Kudos for Google not caving into the whiners.
My own vanity search revealed that Google has only indexed a very small amount of code that I’ve made available on the Web. (Of course not all the code I’ve made available has my name on it.) I am really surprised Warrick hasn’t been indexed yet considering the code has been available for quite some time. It’s possible that switching the URL where the source code is located when the version changes it is causing Google to be a little skittish.
