CSC151.01 2015S, Class 07: Writing Your Own Procedures, Continued

Overview

Preliminaries

I see that some of you have started to experience the rush of "I got it to work!"
Some of you received comments on Lab 3.
- We'll only send comments on things that are clearly special or need feedback (or both).
- It's okay to be wrong, as long as you indicate that you know you are wrong.
- Everyone who turned in lab 3 still got credit; the comments are mostly to help you learn. (They mostly take the form "If Scheme computes a square root incorrectly, asking Scheme to check the answer is probably a bad idea.")
Quiz today!
Note: You should probably switch off who is on the keyboard every ten minutes or so.

Assignment 3.
- Due next Tuesday at 10:30 p.m.
- Don't forget the prologue and epilogue!

Comments from the Podium

Some of you have figured out that it's easier to navigate the classroom if you use the coat hooks at the back of the room. (It keeps your coats in nicer shape, too.)
Citation of "I learned this with _" is hard.
- If you look at it, you should cite it.
- It's nice to cite immediate predecessors (I just learned about X with _, I used that idea here.)
It's Friday! It's PSA time.
- I'm growing to care about you as people, and so I want to see you happy and healthy. (Or at least I don't want to see you unhappy and unhealthy.)
- If you drink, drink responsibly.
- Consent is necessary. Giving and receiving consent while impaired is difficult, if not impossible.
- Consider choices in advance.
- Most reasonable choices are not uncommon. But also consider health risks of some choices.

Adding Neighbors

How well does your add-smaller-right-neighbor work with (drawing-of-square 20 30 40)?
