Looking at our past so as we
can better understand today

Those who cannot
remember the past are
condemned to repeat it.

  • Operation Barbarossa – 1941
    Hitler decides to invade Russia
    Blitzkreig -> all over by late Sep 1941
    Reasons for failure:
    1) logistics – speed left support for front line troops lagging far behind
    2) resilience of Soviet forces
    3) brutal weather

  • May 1942, Winston Churchill
    There is a winter, you know, in Russia," he said. "For a good many months the temperature is apt to fall very low. There is snow, there is frost, and all that. Hitler forgot about this Russian winter. He must have been very loosely educated. We all heard about it at school; but he forgot it. I have never made such a bad mistake as that."
  • 1812 – Napoleon invaded Russia
    At the time invincible, but returned with 40K of his original army of 640K
    Problems?
    1) logisitics – used to foraging & forced marches, here left animals + soldiers dead
    2) resilience of soviet forces – continuous retreat / regrouping & burning fields
  • prehistory
  • prehistory
  • Led to development of commerce + math
     previously one for one matching to count / add / subtract
  • Pascaline – first mechanical computing machines (1642)
  • Vacuum tubes invented = transition to electronics
  • ENIAC (first electronic computer) – 1946
    designed for military
    could not store programs
    Designed for military & first used in calculations for atomic bomb
  • 1948 – transistor invented (replaced vaccuum tubes)Huge size difference
  • Integrated circuits are born
    equivalent of millions of transistors
  • Internet is becoming new super computer - shared

    5. 5. operate the machine Consider these planes (an ancient tool): their designers sought fitness for use, ease of use, good control, long-lasting materials, a good feel in the hand, efficiency of operation, precise adjustment. In use over time, these tools come to be loved by their owners.
    6. 6. pre-computer Most of the qualities we seek in a machine have been valued through the ages. • useful • usable • desirable • affordable for the right people • appropriately complex • appropriately styled • appropriately adaptable, extensible, malleable • overall, having “good fit” with people, context, activity, result

    14. 14. the mac taps into pent-up desire for ease and pleasure of use Then, during the 1984 Superbowl, you see the first commercial for the Macintosh (directed by Ridley Scott of Blade Runner fame). A crowd of solemn men is gathered in a gloomy auditorium, listening to a ranting bureaucrat on a huge screen. Think of a world full of command-line interfaces… An athletic woman in colorful clothing runs into the auditorium, carrying a huge hammer… …which she throws into the screen, smashing the image and voice of the status quo. hello.

    16. 16. Ergonomic tips in using computers Ergonomics is the science of designing the job, equipment, and workplace to fit the worker. Proper ergonomic design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long-term disability
