// John! If you'll svn remove this once more,

你怎么看?下面的代码是安全的“svn删除”。

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.

问:“你遇到过的源代码中最好的注释是什么?”

A:很简单——就是那个帮我解决了我当时遇到的任何问题的人，而且有很多这样的人!

其次是那些帮助指导新开发避免已知陷阱的方法。

注意上面代码中的bug;我只是证明了它是正确的，并没有尝试过。
