Yeah you dumbasses should just use the search function available in every book on the shelf..
/sarcasm
Actually.. Sometimes it's nice to have answers which you know right at your finger tips. Just so you can verify that you are not going crazy. Also sometimes it's easier to search the net for something than it is searching a book for something that may or may not be in the index. Also, posts like this are easier for most people to read than cs books.
