I'd say that my most controversial opinion on programming is that I honestly believe you shouldn't worry so much about throw-away code and rewriting code. Too many times people feel that if you write something down, then changing it means you did something wrong. But the way my brain works is to get something very simple working, and update the code slowly, while ensuring that the code and the test continue to function together. It may end up actually creating classes, methods, additional parameters, etc., I fully well know will go away in a few hours. But I do it because i want to take only small steps toward my goal. In the end, I don't think I spend any more time using this technique than the programmers that stare at the screen trying to figure out the best design up front before writing a line of code.

我得到的好处是，我不必不断地处理那些因为我碰巧以某种方式破坏了它而不再工作的软件，并试图找出停止工作的原因和原因。

单身人士并不邪恶

There is a place for singletons in the real world, and methods to get around them (i.e. monostate pattern) are simply singletons in disguise. For instance, a Logger is a perfect candidate for a singleton. Addtionally, so is a message pump. My current app uses distributed computing, and different objects need to be able to send appropriate messages. There should only be one message pump, and everyone should be able to access it. The alternative is passing an object to my message pump everywhere it might be needed and hoping that a new developer doesn't new one up without thinking and wonder why his messages are going nowhere. The uniqueness of the singleton is the most important part, not its availability. The singleton has its place in the world.

根据我得到的大量反馈，我最具争议的观点显然是，程序员并不总是读他们声称读过的书。这紧跟着我的观点，一个受过正规教育的程序员比一个自学成才的程序员更好(但不一定比另一个自学成才的程序员更好)。

编写完代码后再编写规格说明。(如果有的话)

In many projects I have been involved in, a great deal of effort was spent at the outset writing a "spec" in Microsoft Word. This process culminated in a "sign off" meeting when the big shots bought in on the project, and after that meeting nobody ever looked at this document again. These documents are a complete waste of time and don't reflect how software is actually designed. This is not to say there are not other valuable artifacts of application design. They are usually contained on index cards, snapshots of whiteboards, cocktail napkins and other similar media that provide a kind of timeline for the app design. These are usually are the real specs of the app. If you are going to write a Word document, (and I am not particularly saying you should) do it at the end of the project. At least it will accurately represent what has been done in the code and might help someone down the road like the the QA team or the next version developers.

将XML存储在关系数据库中的CLOB中通常是一种可怕的逃避。它不仅在性能方面很糟糕，还将正确管理数据结构的责任从数据库架构师转移到应用程序程序员身上。

有一次，我从一位同事那里看到了以下内容:

compareto (b) == 0;

我说他不能在一般情况下这样假设，但他只是笑了。
