今天，软件工程师不仅需要知道如何高效编程，还得知道怎样树立正确的工程实践，以便其代码库得以可持续地健康发展。本书强调了编程和软件工程之间的区别。
软件工程师该如何管理一个活跃的代码库，使其在生命周期中不断发展并响应时刻变化的需求？基于在Google的工作经验，软件工程师Titus Winters和Hyrum Wright以及技术作家Tom Manshreck，坦率而深刻地讲述了一些世界优秀的从业者如何构建和维护软件。本书介绍了Google独特的工程文化、流程和工具，这些方面如何提高工程组织的效率。

铁达时·温特斯 Titus Winters，Google资深软件工程师，是Google C++代码库的负责人：每月有数以千计的各色工程师编辑2.5亿行代码。
