For code, the best way is a URL to the bug tracker or commit log which shows all of your contributions. Use bit.ly if need be. A surprising number of people will list projects they've barely contributed to, using languages they barely know. If you have 2 or 3 projects to list, an "Open Source Contributions" section is fine with me. The main thing to avoid is fancy formatting. How you divide things up into sections is not a big deal. I like this article because I got my job this way. :)
