A novice asked the Master: ``Here is a programmer that never designs, documents or tests his programs. Yet all who know him consider him one of the best programmers in the world. Why is this?‘’
The Master replies: ``That programmer has mastered the Tao. He has gone beyond the need for design; he does not become angry when the system crashes, but accepts the universe without concern. He has gone beyond the need for documentation; he no longer cares if anyone else sees his code. He has gone beyond the need for testing; each of his programs are perfect within themselves, serene and elegant, their purpose self-evident. Truly, he has entered the mystery of Tao.‘’
“A null pointer points to regions filled with dragons, demons, core dumps, and numberless other foul creatures, all of which delight in frolicing in thy program if thou disturb their sleep.”
