Is There a Constraint on Your System?

Most important things we have been learning about programming originated with people who did not have access to very large computers. We can all benefit by in occasional toy programmes when artificial restrictions are set up so that we are forced to push our abilities to the limit. The art of tackling many problems with all our energy will sharpen our talents for the real problems. And the experience will help us to get more sure from our accomplishments on less restricted equipment.
