O'Reilly, the popular publisher of IT books, is releasing an interesting online code search tool that allows you to search for sample code found in the examples of nearly 700 of its books.
With Google Code Search around, one can very easily find a programming function that performs what he needs. I think that such ease of search might entice many computer science students into using it to help them out with their programming assignment. It's a brave new world, I believe it will change the way things are done in the software development world. Google is giving another massive push to open source which is qualitatively different from any other push open source had ever been given.
Refer to the Google Code Search FAQ for more info about its functionality.
