X Window’s Principles

The main principles of “X Window System” desgin. Source from en.wikipedia.org

  • Do not add new functionality unless an implementor cannot complete a real application without it.
  • It is as important to decide what a system is not as to decide what it is. Do not serve all the world’s needs; rather, make the system extensible so that additional needs can be met in an upwardly compatible fashion.
  • The only thing worse than generalizing from one example is generalizing from no examples at all.
  • If a problem is not completely understood, it is probably best to provide no solution at all.
  • If you can get 90 percent of the desired effect for 10 percent of the work, use the simpler solution.  “Worse is better.”
  • Isolate complexity as much as possible.
  • Provide mechanism rather than policy. In particular, place user interface policy in the clients’ hands.
