The beauty of software is in its function, in its internal structure, and in the way in which it is created by a team. To a user, a program with just the right features presented through an intuitive and(作答此空)interface is beautiful. To a software designer, an internal structure that is partitioned in a simple and intuitive manner, and that minimizes internal coupling is beautiful. To developers and managers, a motivated team of developers making significant progress every week, and producing defect-free code, is beautiful. There is beauty on all these levels.
Our world needs software--lots of software. Fifty years ago software was something that ran in a few big and expensive machines.

It would be a great shame if, in all that software，there was no beauty.
