**Thus spake the master programmer:**

**编程大师如是说:**

"Though a program be but three lines long, someday it will have to bemaintained."  
“既使一个程序只有三行长,也总有一天需要去维护它”

**A manager asked a programmer how long it would take him to finish theprogram on which he was working. "I will be finished tomorrow," theprogrammer promptly replied.**

**经理问程序员要多长时间才能完成他的项目。“明天”**

**"I think you are being unrealistic," said the manager. "Truthfully, howlong will it take?"**

**“太不着边际了,老实说,要多久?”**

**The programmer thought for a moment. "I have some features that I wishto add. This will take at least two weeks," he finally said.**

**程序员想了一想说。“还有一些新的功能要加进去,可能至少要两个星期吧。”**

**"Even that is too much to expect," insisted the manager, "I will besatisfied if you simply tell me when the program is complete."**

**“即使两个星期恐怕也太夸张了,什么时候你只要告诉我说程序已经完成就好了。”**

**The programmer agreed to this.**

**Several years slated, the manager retired. On the way to his retirementlunch, he discovered the programmer asleep at his terminal. He had beenprogramming all night.**

**几年后,这个经理已经退休了,在他的离职午餐上,他发现这些程序员在他的终端前睡着了,他整夜都在编程。**

**A novice programmer was once assigned to code a simple financial package.**

**一个初学者被要求编写一个财务软件。**

**The novice worked furiously for many days, but when his master reviewedhis program, he discovered that it contained a screen editor, a set ofgeneralized graphics routines, and artificial intelligence interface,but not the slightest mention of anything financial.**

**他疯狂地工作了很多天,但他的主管检视他的程序时发现,它写了一个编辑嚣,一个图形程序集,和人工智能的界面,但是看不到任何跟财务有关的东西。**

**When the master asked about this, the novice became indignant. "Don't beso impatient," he said, "I'll put the financial stuff in eventually."**

**主管要求解释时,程序员被激怒了:“你太没耐心了,我会在最后写财务的部分。”**

**一个好的老师不会不管哪怕是最差的学生。**

**一个好的父亲不会让他的任何一个孩子挨饿。**

**一个好的程序员不应拒绝维护他的程序。**
