For those interested in getting a job working with Open Source software, I'd also recommend reading the recently published interview with Todd Cranston-Cuebas (Senior Tech Recruiter at Ticketmaster/Citysearch) entitled "How To Get Hired As An Open-Source Developer". It contains some insightful tips on what clueful recruiters are looking for in candidates for Open Source positions along with some nice suggestions regarding what to include (or not include) in your resume.
