  6. “If the automobile had followed the same development as the computer, a Rolls-Royce would today cost $100, get a million miles per gallon, and explode once a year killing everyone inside." • - Robert Cringely

  8. “Better, Faster, Cheaper”

  9. The USS Yorktown “After a crew member mistakenly entered a zero into the data field of an application, the computer system proceeded to divide another quantity by that zero. The operation caused a buffer overflow, in which data leaked from a temporary storage space in memory, and the error eventually brought down the ship's propulsion system. The result: the Yorktown was dead in the water for more than two hours.”

  10. Some Advice

  11. “Objects in calendar are closer than they appear”

  12. Fail fast

  13. “It was a dark and stormy night…”

  14. Learn to express yourself in code

  15. Hi!

  16. Don’t be afraid of the faculty

  17. Be a good team member and leader

  18. “Students learn first and foremost from each other, and bringing them all together is the most important role of the university.” — From “Quality Communication through Time and Space” James Morris, 1982

  19. Think for yourself

  20. History

  21. :-)

  22. Gates Center for Computer Science

  23. Multimedia email • MIME • Andrew Message System • Mulberry • Cyrus • …

  24. Wired campuses • And free internet access • Established by CMU in 1982...

  25. Java, Common Lisp • Design projects started at CMU...

  26. Who are you? • >26 different states, >12 countries • Median SAT near 1500 • ~40 novice/beginner programmers • ~33% women • 96% predict graduating in the top half of the class • The best students ever to walk the CMU campus.

  27. Early curriculum • Very intensive • Attempts to give everyone a basic CS background in first two years • Very open second two years • Three different programming languages

  28. “Programs must be written for people to read, and only incidentally for machines to execute.” • — Abelson and Sussman

  29. “Programming is an explanatory activity.” • — Robert Harper

  30. “If we spoke a different language, we would perceive a somewhat different world.” • — Wittgenstein

  31. “C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, it blows away your whole leg.” • —Bjarne Stroustrup

  32. “The problem with using C++ ... is that there's already a strong tendency in the language to require you to know everything before you can do anything.” • — Larry Wall

  33. “If you want a language that tries to lock up all the sharp objects and fire-making implements, use Pascal or Ada: the Nerf languages, harmless fun for children of all ages, and they won't mar the furniture.” • — Scott Fahlman

  34. Be open-minded and have fun

  35. “Once a logical formalism is established one can expect that a systematic, so-to-say computational, treatment of logic formulas is possible, which would somewhat correspond to the theory of equations in algebra.” • —Hilbert, 1908

  36. “I expect that digital computing machines will eventually stimulate considerable interest in symbolic logic… The language in which one communicates with these machines … forms a sort of symbolic logic.” — Alan Turing
