The Humble ProgrammerTuring Award Lecture, E.W. Dijkstra, 1972

We shall do a much better programming job,

• provided that we approach the task with a full appreciation of its tremendous difficulty,

• provided that we stick to modest and elegant programming languages,

• provided that we respect the intrinsic limitations of the human mind, and

• approach the task as Very Humble Programmers


Maarten LooijenComputer Scientist

Meaning of life,

I consider the happiness and usefulness,

is the purpose of our life,

meaning of our life.

The very existence of our life,

is surely not for trouble,

not for suffering.
