We instituted peer reviews to help identify bugs before they hit production, and we observed something very interesting: few bugs were being identified during the reviews.

我们建立了同级评审来帮助我们在应用系统的bug影响生产环境的系统之前识别出他们，并且我们观察到一些事情非常有趣：在评审过程中很少的bug被识别出来。

As a rule, code compiled with full optimization can be difficult or impossible to debug, making it very difficult to identify bugs that may be causing the system to function incorrectly.

通常，经过完全优化的编译代码很难或者几乎不可能进行调试，这就加大了发现那些造成系统功能错误所在的难度。
