Being abstract is something profoundly different from being vague… The purpose of abstraction is not to be vague, but to create a new semantic level in which one can be absolutely precise. — Edsger Dijkstra
抽象和模糊完全地不同，抽象的目的并不是把事情变模糊，而去创建一个新的语义层，在那里是绝对精确的描述。 — Edsger Dijkstra
Commentary: most debugging problems are fixed easily; identifying the location of the problem is hard. — unknown
修复bug很容易，但是定位bug却很困难 – 匿名
Given enough eyeballs, all bugs are shallow (e.g., given a large enough beta-tester and co-developer base, almost every problem will be characterized quickly and the fix obvious to someone). — Eric S. Raymond, programmer and advocate of open source software, from The Cathedral and the Bazaar
只要给于足够的重视，所有的bug浮现出来(比如：只要给于足够多的beta测试者和开发人员一起工作，那么，几所所有的问题都会很快的出现，而修正也会是显而易见的）
Programs must be written for people to read, and only incidentally for machines to execute. — Harold Abelson and Gerald Jay Sussman, computer scientists and authors, from The Structure and Interpretation of Computer Programs
代码应该是写给其他人来读的，而能让机器运行的仅仅是附带着的。—— Harold Abelson 与 Gerald Jay Sussman, 计算机科学家和作家，摘自《The Structure and Interpretation of Computer Programs》
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, object-oriented programming expert at Bell Labs
开始的90%的代码用了90%的开发时间，而剩下的最后的10%的代码会需要另外90%的开发时间。– Tom Cargill,面向对象编程专家,贝尔实验室
The sooner you start to code, the longer the program will take. — Roy Carlson, University of Wisconsin
你越早开始都手编码，你所花费来编程的时间就越长 — Roy Carlson, University of Wisconsin
The value of a prototype is in the education it gives you, not in the code itself. — Alan Cooper, software author, from The Inmates are Running the Asylum
原型的价值在于他给你的教训，而不是代码自身 — Alan Cooper, software author, from The Inmates are Running the Asylum
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. — Charles Antony Richard Hoare
世界上有两个设计软件的方法，一种方法是设计的尽量简单，以至于明显的没有什么缺陷，另外一种方式是使他尽量的复杂，以至于其缺陷不那么明显。
Weeks of programming can save you hours of planning. — unknown
多做几周的编程可以节省你做计划的时间 —— 匿名 （意思为，只有实践过了，你才更容易做计划，没有实践过，做起计划来将会很头痛）
