内容简介
如果你是个程序员的话，那么你就需要本书，本书帮助你：当需要向一个超过3万行代码的程序中添加新功能时，该从哪里开始呢？该如何去理解一段用来同进解决多件事情的代码呢？当需要解决一个复杂的编边过程时，该从哪里开始呢？可能导致我们阅读代码的原因陋就简：我们不得不去修复它其中所包含的错误，或者是对它进行遍查（inspect）或者是改善它，我们阅读代码的方式可能和工程师检查机械的方式一样：找出它的工作原理，或者我们阅读代码的目的是对代码进行清理：找出其中可以被重用的部分阅读代码有它自身的技巧，并需要我们能够在重要场合对采用何种技术有判断能力，在这本不可或缺的书中，Diomidisspinellis使用了超过6个来自现实世界中的例子来向我们展示如何鉴别好的或坏的代码，如何去阅读它，从中去找寻什么，以及如何利用这种技巧来提升我们自身编写的代码的品质，请记住这个事实，如果我们养成了阅读好代码的习惯，我们就能写出品质更高的代码。
作者简介
DiomidisSpinellis从1985年起，就为许多具有创造性的并获得广泛赞誉的商业及开源项目编写和维护超过了250000行代码，与此同时他与逐步完善了本书中所介绍的技术。他从伦敦大学帝国学院获得了软件工程学科的工程学硕士学位和计算机科学学科的博士学位。现在他是雅典经贸大学管理科学及技术系的助理教授。
