《编程之道》 －－设计

Thus spake the master programmer:

"When the program is being tested, it is too late to make design changes."

编程大师如是说：

”当程序被测试时，再修改设计方案就太迟了。“


There was once a man who  went  to  a  computer  trade  show.

Each day as he  entered,  the man told the guard at the door:" I am a great thief, renowned for my feats of

shoplifting. Be forewarned, for this trade show shall not escape unplundered."

This speech disturbed the guard greatly, because there were millions of dollars of computer equirpment

inside, so he watched the man carefully. But the man merely wandered from booth to booth, humming

quietly to himself.

When the man left, the guard took him aside and searched his clothes, but nothing was to be found.

On the next day of the thrade show, the man returned and chided the guard, saying:" I escaped with a vast

booty yesterday, but today will be even better." So the guard watched him even more closely, but to no avail.

On the final day of the trade show, the guard could restain his curiosity no longer. "Sir Thief," he said, " I am

so perplexed, I cannot  live in peace. Please enlighten me. What is it that you are stealing?"

The man smiled. " I am stealing ideas," he said.
