Most of the project participants didn't come to the project with the kind of skills enumerated, but they reflect the baseline at which we get significant productivity from a contributor. Some of the cultural factors that are harder to describe include:

• being a self-starter, we don't hold hands well
• good diagnostic skills in problem resolution
• being a quick learner
• having a high attention to detail
• low tolerance for bugs and a focus on correctness and security
