  18. A Word on the Honor Code...

  19. A Word on the Honor Code... ● Feel free to discuss general ideas with other students, but do not share any programs or code (text of the programs). ● Cite all sources you use and everyone you collaborated with. ● This is not an exhaustive list; please see Handout #03 for a full discussion of the Honor Code.

  20. On a Happier Note... ● There are 38 hours a week where we're available to help you! ● Section leaders and course helpers staff the Tresidder LaIR Sunday – Thursday, 6PM – Midnight. ● Starts next Tuesday. ● Keith and Jeremy hold office hours each week. ● See Handout #00 for details.

  21. Why Learn to Program Computers?

  22. Computer science is no more about computers than astronomy is about telescopes, biology is about microscopes or chemistry is about beakers and test tubes. Science is not about tools, it is about how we use them and what we find out when we do. - Michael Fellows and Ian Parberry, “SIGACT trying to get children excited about CS”
