Linux tips: Recovering lost text data from disk, or EVEN MEMORY

Okay, first new post for the new 'technical' blog. The topic is "Holy ****!!! I just had my browser/text editor crash, and I've lost all that work! What do I do now?"

Well, so long as the editor you were using stores it's data in some form of plain text, and so long as you are using linux, freebsd, or some other unix, (or possibly Mac OSX), I may be able to help.
