Will that change? : I certainly hope so. My goal is that you can finish lab during class time. Can you explain the difference between `modulo` and `remainder`? : It's not relevant right now. Did you have a nice dinner with the trustees? : Yes. Although I don't always agree with them, we share a strong commitment to this institution. Do you mind receiving email question? : No, not at all. Quiz ---- * Work on the quiz. * When you are done, put down your pencil or pen and meditate quietly. * When the buzzer beeps, please pass your quizzes to the east, where our mentors will gather them. Lab Time -------- _We'll work on the procedures lab until 9:25 or so._ * If you had finished the lab already, you may * (a) do the "For those with extra time" * (b) work on the homework assignment Homework note: Neurobiology breaks the formatting policy. Change it to read -1 24 rather than -13 12. "79911 BIO-363-01 4.00 -13 12 Neurobiology w/lab" "79911 BIO-363-01 4.00 -1 24 Neurobiology w/lab" Homework note. Over the longer term, you will be better off using the following format for procedure definitions that use lambda. (define proc (lambda (param) body)) Basics of pair programming -------------------------- _Suppose the rest of the class had not done the reading. Explain._ * Two people working on the computer * Driver: One doing the typing of othe code * Navigator: The other looking over their shoulder * The driver and navigator should be communication. * Which means the driver should be talking out loud about their though process. * The navigator can * Point out errors * Suggest other approaches (e.g., "This would be so much nicer if ..") * Ask questions * Take a big-picture view * Serve as a reference Benefits of pair programming ---------------------------- _Suppose the rest of the class had not done the reading. Suggest benefits._ * Better code. * Learn new ways to solve. * Talking out loud about problems in the code helps you find them. Exercise -------- _Our mentors have distributed cards with simulated quotations from past CSC 151 students. Please read your cards aloud._ Forming a code of conduct ------------------------- Lab writeup: ... * Something you'd like to see in the code of conduct.
