献给那些有云计算背景知识，准备投身OpenStack学习和研究的开发者们
开源社区 开源社区不仅仅是一种生产模式，同时也是一种基于项目活动之上的交流模式。社区不会强制成员该怎么做，它只会鼓励成员该怎么做。 本质：一群技术人员 开源精神：开放、互助、参与、分享 对项目有兴趣：乐于参与项目的运作、开发、测试、维护等 主要来源：与项目利益相关的企业/组织、个人开发者、科研机构 开源项目核心成员的主要特征 开发能力强，经验丰富 对项目所在领域的产品或者类似项目的理解和参与经验，对项目所在领域核心技术的掌握 对项目的设计思想、架构演进、关键特性实现等方面的理解 较高的代码质量 长期跟踪项目，并作出个人贡献 参与设计，实现feature，修正bug，review代码等等 项目的核心负责人 具备项目经理和产品经理的双重技能 从项目创始初期即作为核心贡献者参与项目
