“If computers of the kind I have advocated become the computers of the future, then computing may someday be organized as a public utility just as the telephone system is a public utility … The computer utility could become the basis of a new and important industry.” - John McCarthy, American Computer Scientist, MIT Centennial, 1961

When Simple isn’t Easy – Git Want to be an OpenStack Contributor?

• Git has a Learning Curve

• It may or may not make perfectly intelligent people feel dumb

• You may or may not learn how to do something, not use it for a week, and feel like you’re starting over again

• Tutorials online may or may not assume you already know basics of version control and git branch strategy

• It may or may not be hard when you’re missing something “obvious” to folks with git experience

14RACKSPACE® HOSTING | WWW.RACKSPACE.COM

When Simple isn’t Easy - ReviewsWant to be an OpenStack Contributor

• To merge, a patch must be reviewed – Various voting and non-voting jobs

– +1 from two Project cores (+2)

• Those smart people you get to work with? They have opinions. Usually strong ones.

• Your Great Idea may not fit with the release cycle goals or the direction of the project.

• Your approach to content creation (coding, writing, translation, etc) may be different than someone else’s and you may be blocked as a result

• Core Reviewers are an endangered species who often don’t have time to be “nice” in comments (but they are!)

Don’t give up! The review process is a great way to learn python and OpenStack from experienced

developers who want you to succeed.

15RACKSPACE® HOSTING | WWW.RACKSPACE.COM

• Join in through launchpad and the Foundation

• Sign up for some mailing lists and join an IRC channel (or ten)

“We may actually have enough developers right now. What we need are all those other types of people.” Paraphrase of Russell B., former Nova PTL, from Mid-Cycle Meetup in Utah
