An anonymous reader writes "This is the first article I've ever read specifically about hiring open source developers, and how to judge their ability not just to code but to work with others. It's reprinted over at ITMJ [part of OSDN, as this site is] from a book by Martin Fink, the General Manager for HP's Linux Systems Division. Brings up a lot of good points, including how you need to make sure your open source people are developing things (on company time) that do the company some good, not just scratching their own itches. Fun quote: 'Discover what pseudonyms your candidate uses online. Look at the archives at SlashDot and other online locales. Does your candidate hide behind secret pseudonyms to trash other individuals? Is there passion without condemnation?'"
