生命太短暂，不要去做一些根本没有人想要的东西。——Ash Maurya，Running Lean 作者

如果你交给某人一个程序，你将折磨他一整天；如果你教某人如何编写程序，你将折磨他一辈子。——David Leinweber

软件设计有两种方式：一种方式是，使软件过于简单，明显没有缺陷；另一种方式是，使软件过于复杂，没有明显的缺陷。——C.A.R. Hoare

其实，我尝试着使Ruby更自然，而不是简单。Ruby看起来很简单，但内部是非常复杂的，就像我们的身体一样。——松本行弘，Ruby之父

大部分情况下，构建程序的过程本质上是对规范调试的过程。——Fred Brooks，《人月神话》作者

软件开发往往是这样：最开始的90%代码占用了开始的90%的开发时间；剩下10%代码同样需要90%的开发时间。——Tom Cargill

当你试图解决一个你不理解的问题时，复杂化就产成了。——Andy Boothe

用几个小时来制定计划，可以节省几周的编程时间。—— 匿名

控制复杂性是计算机编程的本质。—— Brian Kernighan

计算机科学领域的所有问题都可以通过其他方式间接解决。——David Wheeler

编程是两队人马在竞争：软件工程师努力设计出最大最好的连白痴都会使用的程序；而宇宙在拼命制造最大最好的白痴。到目前为止，宇宙是胜利者。—— Rick Cook

调试一个初次见到的代码比重写代码要困难两倍。因此，按照定义，如果你写代码非常巧妙，那么没有人足够聪明来调试它。—— Brian W. Kernighan

我不是一个伟大的程序员，我只是一个具有良好习惯的优秀程序员。― Kent Beck

你们中大多数人都熟悉程序员的美德，有三种：那就是懒惰、急躁和傲慢。– Larry Wall，Perl語言发明人

任何一个傻瓜都会写能够让机器理解的代码，只有好的程序员才能写出人类可以理解的代码。——Martin Fowler

靠代码行数来衡量开发进度，就像是凭重量来衡量飞机制造的进度。——比尔•盖茨

这不是一个bug，这只是一个未列出来的特性。——匿名

作为一个程序员，郁闷的事情是，面对一个代码块，却不敢去修改。更糟糕的是，这个代码块还是自己写的。—— Peyton Jones

它在我的机器上可以很好运行！——大部分程序员

能说算不上什么，有本事就把你的代码给我看看。——Linus Torvalds，Linux之父

我认为对象就像是生物学里的细胞，或者网络中的一台计算机，只能够通过消息来通信——Alan Kay，Smalltalk的发明人，面向对象之父

当你选择了一种语言，意味着你还选择了一组技术、一个社区。——Joshua Bloch

质量、速度、廉价，选择其中两个。——匿名

过早的优化是罪恶之源。——Donald Knuth

没有什么代码的执行速度比空代码更快。——Merb核心原则

如果你是房间里最聪明的人，那么你走错房间了。——匿名

如果只需更改一个单一的代码行，你的部门需要花费多长时间？——Mary Poppendieck

九个人不能让一个孩子在一个月内出生。——Fred Brooks，《人月神话》作者

好代码本身就是最好的文档。当你需要添加一个注释时，你应该考虑如何修改代码才能不需要注释。——Steve McConnell，Code Complete 作者

一个人在教会电脑之前，别说他真正理解这个东西了。——Donald Knuth

Life’s too short to build something nobody wants – Ash Maurya, Running Lean 作者

Give someone a program, you frustrate them for a day; teach them how to program, you frustrate them for a lifetime. – David Leinweber

There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies and the other way is to make it so complicated that there are no obvious deficiencies. — C.A.R. Hoare

Actually, I’m trying to make Ruby natural, not simple. Ruby is simple in appearance, but is very complex inside, just like our human body. – Matz, Ruby 發明人

Much of the essence of building a program is in fact the debugging of the specification. – Fred Brooks, The Mythical Man-Month 作者

The first 90% of the code accounts for the first 90% of the development time. The remaining 10% of the code accounts for the other 90% of the development time. – Tom Cargill

Complication is what happens when you try to solve a problem you don’t understand – Andy Boothe

Weeks of programming can save you hours of planning. – Unknown

Controlling complexity is the essence of computer programming. — Brian Kernighan

All problems in computer science can be solved by another level of indirection(abstraction) – David Wheeler

…except for the problem of too many layers of indirection. – Kevlin Henney’s corollary

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. — Rick Cook

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 W. Kernighan

I’m not a great programmer; I’m just a good programmer with great habits. ― Kent Beck

Most of you are familiar with the virtues of a programmer. There are three, of course: laziness, impatience, and hubris. – Larry Wall, Perl 程式語言發明人

Any fool can write code that a computer can understand. Good programmers write code that humans can understand. – Martin Fowler

Measuring programming progress by lines of code is like measuring aircraft building progress by weight. – Bill Gates

It’s not a bug – it’s an undocumented feature. – Unknown

The most depressing thing about life as a programmer, I think, is if you’re faced with a chunk of code that either someone else wrote or, worse still, you wrote yourself but you no longer dare to modify. That’s depressing. – Peyton Jones

It works on my machine! – 數以萬計的程式設計師

Talk is cheap. Show me the code. – Linus Torvalds

I thought of objects being like biological cells and/or individual computers on a network, only able to communicate with messages — Alan Kay, Smalltalk 發明人

When you choose a language, you’re choosing more than a set of technical trade-offs—you’re choosing a community. -Joshua Bloch

Quality, Speed or Cheap. Pick two. – Unknown

Developer testing isn’t primarily about verifying code. It’s about making great code. If you can’t test something, it might be your testing skills failing you but it’s probably your code code’s design. Testable code is almost always better code. – Chad Fowler

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. – Donald Knuth

No code is faster than no code. – Merb core tenet

If you’re the smartest person in the room, you’re in the wrong room. – Unknown

How long would it take your organization to deploy a change (to production) that involves just one single line of code? Do you do this on a repeatable, reliable basis? – Mary Poppendieck

Nine people can’t make a baby in a month.  — Fred Brooks, The Mythical Man-Month作者

Good code is its own best documentation. As you’re about to add a comment, ask yourself, ‘How can I improve the code so that this comment isn’t needed?’ Improve the code and then document it to make it even clearer. – Steve McConnell, Code Complete 作者

A person does not really understand something until after teaching it to a computer. – Donald Knuth
