A co-worker emailed this to me—the Complete Pasta Theory of Software:

The ideal software structure is one having components that are small and loosely coupled; this ideal structure is called ravioli code. In ravioli code, each of the components, or objects, is a package containing some meat or other nourishment for the system; any component can be modified or replaced without significantly affecting other components.

We need to go beyond the condemnation of spaghetti code to the active encouragement of ravioli code.
