1. What does Dijkstra say is the "major cause" of the software crisis?

Machines have become several orders of magnitude more powerful.


2. What does it mean to be a "very humble programmer"?

Respect our limits.  "appreciate tremendous difficulty", "stick to modest and
elegant programming languages", "respect the intrinsic limiations of the human mind"


3. Hoare oversaw a software project that had to be abandoned. What was it, and why did it have to be abandoned?

An ALGOL compiler.  It only managed 2 chars/sec, later improved to 8.


4. Name one similarity in the suggestions from Dijkstra and Hoare on how to build software.

Keep things simple / avoid complexity
