Computers don't mean computation to people any more. What do they mean? (Still based on computation!)

• data processing, word processing, etc.
• people:
  • bulletin boards
  • instant-messaging
  • newer client-server protocols for reading mail, etc
  • the "world-wide web"
  • "broadband" home internet access -- some furious driving force -- the web?
  • a plethora of interesting social stuff these days, especially around the web. e.g. "blogs", "social networking"

internet security situation: small village to smelly big city

• history starting with unlocked doors, only academic interest in security, some people thought security issues "should" be fixed
• 1988 Morris worm
• most stuff 99% secure
• nowadays, 99% secure is no better than 0.
