"Simplicity is a necessary precondition for reliability."
- Edsger W. Dijkstra (handwritten annotation to EWD498)
"A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over, beginning with a working simple system."

Some searching today found a wikiquote page[2] which led me here[3] also claiming an EWD498 handwritten annotation as the source.
Do you know definitively whether the annotation appears in EWD498?
(I thought at one time I actually found an image with the handwritten annotation, but I can't find it at the moment... Maybe I dreamed that...)
