在linux 1.0内核调度器(schedule .c)中:

Dijkstra可能讨厌我。

/*
 *  'schedule()' is the scheduler function. It's a very simple and nice
 * scheduler: it's not perfect, but certainly works for most things.
 * The one thing you might take a look at is the signal-handler code here.
 *
 *   NOTE!!  Task 0 is the 'idle' task, which gets called when no other
 * tasks can run. It can not be killed, and it cannot sleep. The 'state'
 * information in task[0] is never used.
 *
 * The "confuse_gcc" goto is used only to get better assembly code..
 * Dijkstra probably hates me.

几年前，我在一个没有单元测试可言的大型代码库中工作。

代码中隐藏了一个执行一些日历计算的方法。它有点坏了，由于一些不幸的情况，不得不以一种非常笨拙的方式处理夏令时。

我们不得不修了几次，每一次，我们都会在几个月后发现一些东西坏了。

在花了一整天的时间修复和分析之后，我把代码放到了源代码控制中，并附上了这样的评论:

// this code was written after a version trying to do {this} failed because of {reason},
// previously we were doing {this} which failed because of {reason}. This is 
// now written {this} way so that {lots of reasons here}. If you want to touch
// this code, please make sure that it produces the right answers when tested with:
//
// {some sort of unit test}

最终，我的团队被外包了。有时我想知道这段代码发生了什么:)
