unix設計哲學

說到Unix為我們所帶來的軟件開發的哲學，我必需要說一說。Unix遵循的原則是KISS（Keep it simple, stupid）。在https://en.wikipedia.org/wiki/Unix_philosophy 上有很多的基本上大同小異的Unix哲學，都是很經典的。

Doug McIlroy 是認為UNIX的哲學是這樣的：三條哲學，簡明扼要，就是這三條哲學貫穿著整個Unix世界。尤其是第一條“do one thing and do it well”真是相當精彩！

l Write programs that do one thing and do it well.

l Write programs to work together.

l Write programs to handle text streams, because that is a universal interface.

隻要是Unix的程序員，他們會比別的程序員在任何時候都會不停地強調著這三條哲學。

而《The Art of Unix Programming》總結了下麵這些哲學，都是至理名言啊。

Rule of Modularity: Write simple parts connected by clean interfaces.
Rule of Clarity: Clarity is better than cleverness.
Rule of Composition: Design programs to be connected to other programs.
Rule of Separation: Separate policy from mechanism; separate interfaces from engines.
Rule of Simplicity: Design for simplicity; add complexity only where you must.
Rule of Parsimony: Write a big program only when it is clear by demonstration that nothing else will do.
Rule of Transparency: Design for visibility to make inspection and debugging easier.
Rule of Robustness: Robustness is the child of transparency and simplicity.
Rule of Representation: Fold knowledge into data so program logic can be stupid and robust.
Rule of Least Surprise: In interface design, always do the least surprising thing.
Rule of Silence: When a program has nothing surprising to say, it should say nothing.
Rule of Repair: When you must fail, fail noisily and as soon as possible.
Rule of Economy: Programmer time is expensive; conserve it in preference to machine time.
Rule of Generation: Avoid hand-hacking; write programs to write programs when you can.
Rule of Optimization: Prototype before polishing. Get it working before you optimize it.
Rule of Diversity: Distrust all claims for "one true way".
Rule of Extensibility: Design for the future, because it will be here sooner than you think.

X Windows 的設計者 Mike Gancarz 給出了下麵九條哲學思想

在今天，這種思想依然被傳承著，在影響著世界上各個角落的每一個程序員。
