Save the date, mark your calendars, and decline the invite to the All Hands meeting! The second edition of @sfrubyconf is happening Nov 10-12. Our first confirmed keynote speaker is @garrytan, president and CEO of Y Combinator and longtime Rails builder. Ruby on Rails is the common ingredient in success stories like Shopify and GitHub. Last year, we brought together the people building with Rails and the companies shaping its future. This year, we're doing it again in the home to some of Rails' biggest wins.
