Writing Programs You Can Keep in Your Pocket

Why is programming fun?

What delights may its practioner expect as her reward?

The programmer, like the poet, works only slightly removed

from pure thought-stuff.

She builds her castles in the air, from air, creating by exertion of

the imagination.

Yet the program, unlike the poet's words, is real in the sense that it

moves and works.

It prints results, draws pictures, produces sounds, moves arms.

The magic of myth and legend has come true in our time.

One types the correct incantation on a keyboard, and

a display screen comes to life, showing things that never were

nor could be.

-- Frederick P. Brooks, Jr.
