22 條經典的編程引言

過早的最佳化是萬惡之源。Premature optimization is the root of all evil!
- Donald Knuth

在水裡行走和以一個需求規格進行軟體開發，有一點是相同的，那就是如果水或需求都被凍住不了，那麼行走和軟體開發都會變得容易。Walking on
water and developing software from a specification are easy if both are
frozen
- Edward V Berard

Hofstadter 定理：“一件事情總是會花費比你預期更多的時間，就算是你已經考慮過本條Hofstadter 定理”。It always
takes longer than you expect, even when you take into account
Hofstadter’s Law.
- Hofstadter’s Law

有些遇到問題的人總是會說“我知道，我會使用Regex”，那麼，你現在有兩個問題了。（意思是：你本想用Regex來解決你已有問題，但實際上你又引入
了“Regex”的一個新問題）Some people, when confronted with a problem, think “I
know, I’ll use regular expressions.” Now they have two problems
- Jamie Zawinski

偵錯工具的難度是寫代碼的兩倍。因此，只要你的代碼寫的儘可能的清楚，那麼你在調試代碼時就不需要那麼地有技巧。Debugging is twice
as hard as writing the code in the first place. Therefore, if you write
the code as cleverly as possible, you are, by definition, not smart
enough to debug it.
- Brian Kernighan

用程式碼來衡量開發進度，無異於用重量來衡量製造飛機的進度。Measuring programming progress by lines of
code is like measuring aircraft building progress by weight.
- Bill Gates

PHP被一些不合格的業餘人員造就成了一個小惡魔；而Perl則是被一些熟練的但不正當的專業人員造就成了一個超級大惡魔。PHP is a
minor evil perpetrated and created by incompetent amateurs, whereas
Perl is a great and insidious evil, perpetrated by skilled but
perverted professionals.
- Jon Ribbens

在兩個場合我被問到：“請你告訴我，如果你給機器輸入了錯誤的數字，那麼，是否還能得到正確的答案？”我並不能正確領會這類想法。（注意，本引言的作者姓
Babbage，這個名字和神父同名，意思是，作者在反問提問的人，你是問我還是向神父祈禱？）On two occasions I have
been asked, ‘Pray, Mr. Babbage, if you put into the machine wrong
figures, will the right answers come out?’ I am not able rightly to
apprehend the kind of confusion of ideas that could provoke such a
question.”
- Charles Babbage

在編程的時候，我們一定要想像一下，以後維護我們自己的代碼的那個人會成為一個有暴力傾向的瘋子，並且，他還知道我們住在哪裡？Always code
as if the guy who ends up maintaining your code will be a violent
psychopath who knows where you live.
- Rick Osborne

現代的編程是“程式員努力建一個更大更傻的程式”和“世界正在嘗試創造更多更傻的人”之間的一種競賽，目前為止，後者是贏家。Programming
today is a race between software engineers striving to build bigger and
better idiot-proof programs, and the Universe trying to produce bigger
and better idiots. So far, the Universe is winning.
- Rich Cook

我才不關心My Code是否能在你的機器上工作！我們不會給你提供機器。I don’t care if it works on your machine! We are not shipping your machine!
- Ovidiu Platon

我總是希望我的電腦能夠像電話一樣容易使用；我的這個希望正在變成現實，因為我現在已經不知道怎麼去使用我的電話了。I have always
wished for my computer to be as easy to use as my telephone; my wish
has come true because I can no longer figure out how to use my
telephone.
- Bjarne Stroustrup

電腦是一種在人類曆史上所有發明中，可以讓你比以前更快地犯更多的錯誤的發明，同樣，其也包括了“手槍”和“龍舌蘭酒”這兩種發明的缺陷。A
computer lets you make more mistakes faster than any other invention in
human history, with the possible exceptions of handguns and tequila.
- Mitch Ratcliffe

如果偵錯工具是一種標準的可以剷除BUG的流程，那麼，編程就是把他們放進來的流程。If debugging is the process of
removing software bugs, then programming must be the process of putting
them in.
- E. W. Dijkstra

教一群被BASIC先入為主的學生，什麼是好的編程風格簡直是一件不可能的事。對於一些有潛力的程式員，他們所受到的智力上的傷害遠遠超過了重建他們的信
心。It is practically impossible to teach good programming style to
students that have had prior exposure to BASIC. As potential
programmers, they are mentally mutilated beyond hope of regeneration.
- E. W. Dijkstra

理論上來說，理論和實際是一樣的。但實際上來說，他們則不是。In theory, theory and practice are the same. In practice, they’re not.
- Unknown

只有兩個事情是無窮盡的：宇宙和人類的愚蠢。當然，我現在還不能確定宇宙是無窮盡的。Two things are infinite: the
universe and human stupidity; and I’m not sure about the universe.
- Albert Einstein

Perl這種語言就好像是被RSA密碼編譯演算法加密過的一樣。Perl - The only language that looks the same before and after RSA encryption.
- Keith Bostic

我愛“最終期限”，我喜歡“嗖嗖嗖”的聲音就像他們在飛一樣。I love deadlines. I like the whooshing sound they make as they fly by.
- Douglas Adams

說Java好的是因為它跨平台就像好像說肛交好是因為其可以適用於一切性別。Saying that Java is good because it
works on all platforms is like saying anal sex is good because it works
on all genders
- Unknown

XML就像是一種強暴——如果它不能解決你的問題，那隻能說明你沒有用好它。XML is like violence - if it doesn’t solve your problems, you are not using enough of it.
- Unknown

愛因期坦說，自然界中的一切一定會有一個簡單的解釋，因為上帝並不是反覆無常和獨裁的。當然，不會有什麼信仰能程式員像愛因期坦那樣感到舒服。
Einstein argued that there must be simplified explanations of nature,
because God is not capricious or arbitrary. No such faith comforts the
software engineer.
- Fred Brooks
