Object-oriented programming is the current cure-all — although it has been around for much more then ten years. At the core, there is little more to it then finally applying the good programming principles which we have been taught for more then twenty years. C++ (Eiffel, Oberon-2, Smalltalk ... take your pick) is the New Language because it is object-oriented — although you need not use it that way if you do not want to (or know how to), and it turns out that you can do just as well with plain ANSI-C. Only object-orientation permits code reuse between projects — although the idea of subroutines is as old as computers and good programmers always carried their toolkits and libraries with them.

Software Refactoring is an important part of the software development process, especially in the maintenance phase. For many years, several studies revealed that the cost of software maintenance is greater than the cost of development ([Boehm 75], [Lientz & Swanson 80]). Although the problem is recognized, there are not many tools to help maintainers/programmers. A precise, comprehensive, usable, efficient and complete tool for software refactoring is much harder to build than an optimizer, because the later does not need to be usable and comprehensive and complete. It just needs to be precise and efficient in what it does.

重构是持续改进代码的基础。抵制重构将带来技术麻烦：忘记代码片段的功能、创建无法测试的代码等等。 而有了重构，使用单元测试、共享代码以及更可靠的无bug 的代码这些最佳实践就显得简单多了。 鉴于重构的重要性，我决定在整个8 月份每天介绍一个重构。在开始之前，请允许我事先声明，尽管我试 着对每个重构进行额外的描述和讨论，但我并不是在声明它们的所有权。 我介绍的大多数重构都可以在Refactoring.com 中找到，有一些来自《代码大全（第2 版）》，剩下的则是我 自己经常使用或从其他网站找到的。我觉得注明每个重构的出处并不是重要的，因为你可以在网上不同的 帖子或文章中找到名称类似的重构。 本着这一精神，我将在明天发布第一篇帖子并开始长达31天的重构马拉松之旅。希望你们能够享受重构并 从中获益。

Do you remember the first program you wrote? I remember mine. It was a little graphics program I wrote on an early PC. I started programming later than most of my friends. Sure, I'd seen computers when I was a kid. I remember being really impressed by a minicomputer I once saw in an office, but for years I never had a chance to even sit at a computer. Later, when I was a teenager, some friends of mine bought a couple of the first TRS-80s. I was interested, but I was actually a bit apprehensive, too. I knew that if I started to play with computers, I'd get sucked into it. It just looked too cool. I don't know why I knew myself so well, but I held back. Later, in college, a roommate of mine had a computer, and I bought a C compiler so that I could teach myself programming. Then it began. I stayed up night after night trying things out, poring through the source code of the emacs editor that came with the compiler. It was addictive, it was challenging, and I loved it.
