程序设计绝对是一门艺术，而不仅仅是一门技术。

首先程序设计的出发点是，是给别人看，可读、易理解、好维护，如果你的程序只能自己来维护，到你离开这个程序时，你程序也就与你一起离开了这个世界。

为了可读、易理解、好维护，你的程序要有好的设计，而不是一接手就进行东抄抄、西抄抄的写代码工作。

写代码是一个工程，程序设计是一种艺术；如果程序员只注重代码，那就象盖房子时的砌砖匠，只知道照图施工而已。世界那么多令人叹为观止的美丽建筑物，那是设计家的艺术杰作，而不是砌砖匠的艺术杰作。

Keep It Easy Read and Right (from ibm readbooks)

Sometimes good style and efficient runtime performance do not mix. Wherever you face a conflict between the two, choose good style. Hard-to-read programs are

hard to debug, 
        hard to maintain,
                and hard to get right.

Program correctness must always win out over speed.

Make it right before you make it faster.

Keep it right when you make it faster.

Make it clear before you make it faster.

Do not sacrifice clarity for small gains in efficiency.

Keep It Simle and Stupid

Knowledge Intergration is Supper Skill
        What I hear I forget,
                What I see I remember,
                        What I do I understand.

whatever style you use, please use it consistently, since a mixture of styles within one program tends to look ugly. If you are contributing changes to an existing program, please follow the style of that program.
