Mainteance
Book Five

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 be maintained."
“既使一个程序只有三行长，也总有一天需要去维护它”

5.1

A well-used door needs no oil on its hinges.
A swift-flowing steam does no grow stagnant.
Neither sound nor thoughts can travel through a vacuum.
Software rots if not used.
经常使用的门不需要往门轴里上油。
流动的东西就不会停滞不前。
流水不腐，户枢不蠹。
声音和思想都不能在真空里传播。
软件不用就会腐朽。

These are great mysteries.

5.2

A manager asked a programmer how long it would take him to finish the program on which he was working. "I will be finished tomorrow," the programmer 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, how long 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 wish to 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 be satisfied 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 retirement lunch, he discovered the programmer asleep at his terminal. He had been programming 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。

5.3

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 reviewed his program, he discovered that it contained a screen editor, a set of generalized 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 be so 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。”

5.4

Does a good farmer neglect a crop he has planted?
Does a good teacher overlook even the most humble student?
Does a good father allow a single child to starve?
Does a good programmer refuse to maintain his code?
一个好的农民不会不管他的庄稼。
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。

Management
Book Six

Thus spake the master programmer:
编程大师如是说：

"Let the programmer be many and the managers few -- then all will be productive."
“增加程序员，减少经理--这样他们都可提高效率。”

6.1

When managers hold endless meetings, the programmers write games. When accountants talk of quarterly profits, the development budget is about to be cut. When senior scientists talk blue sky, the clouds are about to roll in.
经理们忙于无休无止的会议时，程序员们在写游戏。财务主管在谈论季度盈利时开发预算将会被削减。当老科学家在谈天空的蓝色时，云团蜂拥而至。

Truly, this is not the Tao of Programming.
这不是编程之道。

When managers make commitments, game programs are ignored. When accountants make long-range plans, harmony and order are about to be restored. When senior scientists address the problems at hand, the problems will soon be solved.
经理分配任务时不会包括游戏，会计师做长期计划时，应该做到面面俱到，皆大欢喜。科学家提出一个问题，就会很快得到解决。

Truly, this is the Tao of Programming.
这才是编程之道。

6.2

Why are programmers non-productive? Because their time is wasted in meetings.
为什么程序员没有效率，因为他们把时间都浪费在开会上了。

Why are programmers rebellious? Because the management interferes too much.
为什么程序员难于管理？因为管理者的干预太多了。

Why are the programmers resigning one by one? Because they are burnt out.
为什么程序员一个接一个地辞职，因为他们累坏了。

Having worked for poor management, they no longer value their jobs.
在糟糕的管理下工作，他们享受不到工作的乐趣。

6.3

A manager was about to be fired, but a programmer who worked for him invented a new program that became popular and sold well. As a result, the manager retained his job.
一个经理将被解雇，但他手下的一个程序员写了一个流行的软件并且销路很旺。所以经理保住了他的工作。

The manager tried to give the programmer a bonus, but the programmer refused it, saying, "I wrote the program because I though it was an interesting concept, and thus I expect no reward."
经理为程序员分红，但程序员拒绝了，他说：“我写程序是因为写程序很有趣，所以我并没想过得资金”。

The manager, upon hearing this, remarked, "This programmer, though he holds a position of small esteem, understands well the proper duty of an employee. Lets promote him to the exalted position of management consultant!"
这位经理说，“这位程序员，不管他现在是什么位置，他都能理解一个雇员的职责所在。我们要把他提升为管理顾问”。

But when told this, the programmer once more refused, saying, "I exist so that I can program. If I were promoted, I would do nothing but waste everyone's time. Can I go now? I have a program that I'm working one."
这位程序员又一次拒绝了，他说：“我是一个程序员所以我可以编程，如果我被提升了，除了浪费别人的时间什么也做不了，现在我可以走了吗？我还有一个程序没写完。”

6.4

A manger went to his programmers and told them: "As regards to your work hours: you are going to have to come in at nine in the morning and leave at five in the afternoon." At this, all of them became angry and several resigned on the spot.
经理对程序员说，“你们的工作时间是早上9点到正午点。”，所有的程序员都很不满。

So the manager said: "All right, in that case you may set your own working hours, as long as you finish your projects on schedule." The programmers, now satisfied, began to come in a noon and work to the wee hours of the morning.
经理又说：“好吧，那随你们的便，只要能按时完成任务。”，程序员们这下满意了，他们中午上班，一直工作到凌晨。

Corporate Wisdom
Book Seven

Thus spake the master programmer:
编程大师如是说：

"You can demonstrate a program for a corporate executive, but you can't make him computer literate."
“你可以向一位公司主管演示一套程序，但你不能让他的电脑变得象人一样。”

7.1

A novice asked the master: "In the east there is a great tree-structure that men call 'Corporate Headquarters'. It is bloated out of shape with vice-presidents and accountants. It issues a multitude of memos, each saying 'Go, Hence!' or 'Go, Hither!' and nobody knows what is meant. Every year new names are put onto the branches, but all to no avail. How can such an unnatural entity exist?"
一个新学问大师：“在东方，有一个庞大的机构，人们称作总部。它由为数众多的大小领导。每天发出大量的备忘录，每个备忘录都说：‘干这个，干那个'，没有一个人知道它是什么意思。每年这个机构都会有更多的人加进来而变得越来越大，但是去没有人去做事情。怎么烩样奇怪的东西还能存在呢？”

The master replies: "You perceive this immense structure and are disturbed that it has no rational purpose. Can you not take amusement from its endless gyrations? Do you not enjoy the untroubled ease of programming beneath its sheltering branches? Why are you bothered by its uselessness?"
大师说：“你已经知道这个巨大的机构并不合理，你就不能不管它为什么这样吗？你尽管享受它的好处就是了，干吗要去管它到底是没有效率呢？”

7.2

In the east there is a shark which is larger than all other fish. It changes into a bird whose winds are like clouds filling the sky. When this bird moves across the land, it brings a message from Corporate Headquarters. This message it drops into the midst of the program- mers, like a seagull making its mark upon the beach. Then the bird mounts on the wind and, with the blue sky at its back, returns home.
在遥远的东方，传说有一只巨大的鱼，叫鲲，它变成了一只大鸟，叫鹏，鹏的翅膀可以遮天蔽日，这只大鸟经过陆地的时候，它带来了一个消息，它把这个消息丢在程序员中，就象一只海鸥在海滩上做的记号，然后鹏背负蓝天，乘风而上，回家去了。

The novice programmer stares in wonder at the bird, for he understands it not. The average programmer dreads the coming of the bird, for he fears its message. The master programmer continues to work at his terminal, for he does not know that the bird has come and gone.
初学者惊恐地看着这只鸟，根本不敢相信，中级程序员担心这只鸟的到来，因为它害怕它带来的消息，编程大师则继续在他的终端前工作他根本不知道这只鸟曾经来过。

7.3

The Magician of the Ivory Tower brought his latest invention for the master programmer to examine. The magician wheeled a large black box into the master's office while the master waited in silence.
一个学究带着他的最新发明去见编程大师，他把一个大黑盒子推进大师的办公室。

"This is an integrated, distributed, general-purpose workstation," began the magician, "ergonomically designed with a proprietary operating system, sixth generation languages, and multiple state of the art user interfaces. It took my assistants several hundred man years to construct. Is it not amazing?"
“这是综合的、分布式的通用工作站，”，学究开始介绍了，“按人体工学设计的操作系统，第六代的高级语言，多样的用户界面，整整花了我的助手好几百人年的时间，挺不错吧？”

The master raised his eyebrows slightly. "It is indeed amazing," he said.
大师扬了一下眉毛，说：“的确很了不起。”

"Corporate Headquarters has commanded," continued the magician, "that everyone use this workstation as a platform for new programs. Do you agree to this?"
“头儿已经说了，”这位学究继续说，“每个人都要用这个工作站作平台，你觉得怎么样？”

"Certainly," replied the master, "I will have it transported to the data center immediately!" And the magician returned to his tower, well pleased.
“当然了，”，大师回答说，“我要马上把它送到数据中心去！”，这位学究满意去回去了。

Several days later, a novice wandered into the office of the master programmer and said, "I cannot find the listing for my new program. Do you know where it might be?"
几天后，一个新手走进大师的办公室说，“我找不到我新写的程序了，你知道它可能会在哪儿吗？”

"Yes," replied the master, "the listings are stacked on the platform in the data center."
“当然，”，大师说，“你的程序在数据中心的平台里放着。”

7.4

The master programmer moves from program to program without fear. No change in management can harm him. He will not be fired, even if the project is canceled. Why is this? He is filled with the Tao.
编程大师从一个项目转到另一个项目而豪无顾虑，任何管理上的变动都不能影响他，他不会被解雇，即使项目被取消了。为什么呢？他了解了道。

Hardware and Software
Book Eight

Thus spake the master programmer:
编程大师如是说：

"Without the wind, the grass does not move.
Without software, hardware is useless."
风不动则草不动，没有软件，硬件只是一堆发热的电子器件

8.1

A novice asked the master: "I perceive that one computer company is much larger than all others. It towers above its competition like a giant among dwarfs. Any one of its divisions could comprise an entire business. Why is this so?"
一个初学者问编程大师：“我知道有一家计算机公司比所有其它的公司都大。在它面前它的竞争对手就象站在巨人面前的侏儒。它的任一部门都有各自的业务，为什么会这样呢？”

The master replied, "Why do you ask such foolish questions? That company is large because it is so large. If it only made hardware, nobody would buy it. If it only maintained systems, people would treat it like a servant. But because it combines all of these things, people think it one of the gods! By not seeking to strive, it conquers without effort."
大师说，“为什么你问如此愚蠢的问题呢？那家公司大是因为它就是如此之大，如果它只做硬件，就没有人会买，如果它只维护系统，人们只会把它当作仆人，但是它的业务囊括了所有这些东西，人们就对它顶礼莫拜好象不用努力奋斗就可击败竞争对手

8.2

A master programmer passed a novice programmer one day. The master noted the novice's preoccupation with a hand-held computer game. "Excuse me", he said, "may I examine it?"
有一天编程大师碰见了一个正玩掌上游戏机的编程新手，他说：“给我看一下？”

The novice bolted to attention and handed the device to the master. "I see that the device claims to have three levels of play: Easy, Medium, and Hard", said the master. "Yet every such device has another level of play, where the device seeks not to conquer the human, nor to be conquered by the human."
新手把游戏机递给大师，“我看到上面说明了三种难度的玩法：容易，中等，高难”，大师说，“但是每个这样的游戏机都有另外一种玩法，此时游戏机即不是想着怎么赢你，也不是怎么被你赢。”

"Pray, great master," implored the novice, "how does one find this mysterious setting?"
“那么请问大师”，初学者说，“这种玩法到底是怎样玩的呢？”

The master dropped the device to the ground and crushed it under foot. And suddenly the novice was enlightened.
大师把游戏机摔到地下然后用脚踩碎它，突然初学者明白了。

8.3

There was once a programmer who worked upon microprocessors. "Look at how well off I am here," he said to a mainframe programmer who came to visit, "I have my own operating system and file storage device. I do not have to share my resources with anyone. The software is self-consistent and easy-to-use. Why do you not quit your present job and join me here?"
有一个工作在微机上的程序员对前来参观的大型机程序员说：“看看我这里吧，我有自己的操作系统和文件存储设备，我不需要与别人共享任何资源，软件条条有理并且易于操作。为什么你不辞去你的工作到这里来呢？”

The mainframe programmer then began to describe his system to his friend, saying: "The mainframe sits like an ancient sage meditating in the midst of the data center. Its disk drives lie end-to-end like a great ocean of machinery. The software is a multi-faceted as a diamond and as convoluted as a primeval jungle. The programs, each unique, move through the system like a swift-flowing river. That is why I am happy where I am."
大型机的程序员对他的朋友说：“大型机就象古代圣贤一样深思熟虑，它的磁盘设备从头到尾就象是一个巨大的机械设备的海洋。软件象钻石一样有多个面，象远古的森林一样令人费解。每一个程序都象水经过河流一样穿行于系统中，那就是为什么我乐于为它工作”

The microcomputer programmer, upon hearing this, fell silent. But the two programmers remained friends until the end of their days.
微机程序员听了这些话后，默默不语，但这两个程序员至死都是很好的朋友

8.4

Hardware met Software on the road to Changtse. Software said: "You are the Yin and I am the Yang. If we travel together we will become famous and earn vast sums of money." And so the pair set forth together, thinking to conquer the world.
硬件和软件在路上碰见了，软件说：“你是阴我是阳，如果我们联手就可以赚大钱。”所以它们走到了一直，考虑怎样征服世界。

Presently, they met Firmware, who was dressed in tattered rags, and hobbled along propped on a thorny stick. Firmware said to them: "The Tao lies beyond Yin and Yang. It is silent and still as a pool of water. It does not seek fame, therefore nobody knows its presence. It does not seeks fortune, for it is complete within itself. It exists beyond space and time."
不久，它们遇到了固件，固件衣衫褴褛，拄着一根拐棍步履蹒跚。固件对它们说：“道在于阴阳之外。它静如止水，它从不指望能扬名远近，所以没有人知道它的存在。它也不寻求幸福，它只是与它自己的存在在一起，它存在于空间和时间之外。”

Software and Hardware, ashamed, returned to their homes.
软件和硬件面有惭色，各自回了家。
