 ### end of the formerly uncommented #2001-02-22 John Doe

Many years ago (about 1994) I was working on a Oracle PRO*C application for a large multi-national software company that you will have heard of. The app I was working on was a massive Oracle application and they had a utility that ran overnight tidying up data and doing all sorts of aggregate calculations. Every time anything needed doing as a batch job, it got shoved into this utility and as you can imagine it became an absolute monstrosity. It was also notable for the tiny number of comments that it had for such a massive program.

它为数不多的评论之一仍然是我所见过的对纯粹的WTF的最好的评论……我试图在一个函数中找到一个bug，它有数百行长，中间是函数中唯一的注释:

/* I did this the other way */

直到今天，这仍然是我所见过的最好的评论。

这是我们在大学宿舍使用的自定义DHCP服务器，根据它们是否注册/安装补丁和防病毒，将计算机放入“干净”或“脏”IP地址池:

public boolean getDirty (String MAC) // not as fun as it sounds

在我决定用脚本语言取代它之前，我必须将它添加到旧的数据驱动规则引擎中。

我没有亲身经历过这种情况，但这是一个很好的故事(详见我的评论中的解释):

#define MSGTAG_B33R     0x723 /* RIPLVB */

Fix problem where Nulls don't work properly.  Stupid Microsoft!

代码以迂回的方式一行一行地将null转换为零长度的字符串，因为愚蠢的程序员不理解null是什么，也从未听说过Nz()函数。
