30. Hackers?
“A hacker is someone who thinks outside the box. It's
someone who discards conventional wisdom, and
does something else instead. It's someone who looks
at the edge and wonders what's beyond. It's
someone who sees a set of rules and wonders what
happens if you don't follow them. A hacker is
someone who experiments with the limitations of
systems for intellectual curiosity.”
- Bruce Schneier, Secrets and Lies, 2000
