What do you do with the books you don’t want anymore?

I have lots of books. I buy lots of them, but I don’t want to keep all of them.
Some have already done their job – as the ones I bought to study towards certification. Others are simply bad books.
What do you do with the books you don’t want anymore?
Keep them anyway? Give them away? Sell them? How do you sell them?

I have been interested in computers since I got my hands on a magazine about digital electronics back in 1983 and programming them has been paying the bills since 1991. Having focused on Microsoft-centric technology stacks for the best part of two decades, in recent years I’ve been educating myself on open source technologies such as Linux, networking and the open web platform.
