The unavoidable price of reliability is simplicity.
The competent programmer is fully aware of the limited size of his own skull. He therefore approaches his task with full humility, and avoids clever tricks like the plague.
Edsger W. Dijkstra
Simplicity carried to the extreme becomes elegance.
Simplicity is hard to build, easy to use, and hard to charge for. Complexity is easy to build, hard to use, and easy to charge for.
Simplicity — the art of maximizing the amount of work not done — is essential.
From the Agile Manifesto
Controlling complexity is the essence of computer programming.
Any intelligent fool can make things bigger, more complex, and more violent. It takes a touch of genius — and a lot of courage — to move in the opposite direction.
Complexity kills. It sucks the life out of developers, it makes products difficult to plan, build and test, it introduces security challenges and it causes end-user and administrator frustration.
Increasingly, people seem to misinterpret complexity as sophistication, which is baffling—-the incomprehensible should cause suspicion rather than admiration. Possibly this trend results from a mistaken belief that using a somewhat mysterious device confers an aura of power on the user.
