Ask HN: What's the best practice for organizing your code?

I'm learning to code, and currently I have my code/sites in folders in my home directory. For example, Ruby goes into a "Ruby" folder, HTML/CSS would go into a "Sites" folder, and the two are equal, hierarchically, to the default Documents and Desktop folders.

Is my method the "right" method? I'm aware this could be a method of procrastination, but I don't want to start any habits that could be detrimental to any future work.
