最初的《毁灭战士》拥有一个带有静态墙壁的引擎，但却不能移动;结果，所有的门都是垂直打开的;任何东西都不可能水平移动。当源代码发布后，我在查看代码时，在处理门的源文件中看到了这个，在一大块注释掉的代码的开头:

// UNUSED
// Separate into p_slidoor.c?

#if 0           // ABANDONED TO THE MISTS OF TIME!!!
//
// EV_SlidingDoor : slide a door horizontally
// (animate midtexture, then set noblocking line)
//

try {

}
catch (SQLException ex) {
    // Basically, without saying too much, you're screwed. Royally and totally.
}
catch(Exception ex)
{
    //If you thought you were screwed before, boy have I news for you!!!
}

public function get state( /* of Palestine back */ ):Boolean

I was doing a database in Access, very simple thing - at least it was supposed to be at the start or I would have done it in Delphi. The client wanted to be able to get the customer info out of the database but they would not enter enough information to reliably identify the customer. I told them to use the phone number as the key as each customer (the way they worked, not for everyone) would have a different number. After a few frantic calls from them, (It's not working we can't enter the customer) I discovered that they were too lazy to look up the phone numbers from their old system and were trying to enter all the numbers they did not know as "n/a". In trying to sort this out for them I ended up with a lot of checking loops in the code and had the comment beside one outcome "This should never be reached if they do what they are supposed to do!!!!!!!!!"

他们还曾经问过我:“即使我们输入了错误的地址，我们如何才能找到正确的客户?”而这一切都是为了花生。

我最喜欢的是这样的

大概有5行。

并不难。

这是唯一的评论。
