ESR: the UNIX Philosophy
Snippet from: The Art of Unix Programming
- 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 the "one true way".
- Rule of Extensibility : Design for the future, because it will be here sooner than you think.
