@Tim: In the link you give the question is "I would like to know why the Lasso provides variable selection and ridge regression doesn't.". That seems to be a different question to me. If this question wouldn't be marked as a dup0licate I would like to post an answer.

@boulder this question was already answered in several places, I added few more links as duplicaes.
