Class 28: Pause for Breath

Held Wednesday, October 11, 2000

Summary

Today we take a pause for breath and consider issues on the past two labs and the homework assignment.

Notes

• Don't forget Convo.
• I've taken a look at the schedule and have decided that I'd rather give you the exam after break.
• Sorry for all the problems with CGI. You've encountered problems with our computers being unfriendly and unwilling to tell you when you get something slightly wrong.
  • If a filename is wrong (even by one letter), the CGI script won't work.
  • If the Scheme code is wrong, the CGI script won't work.
  • If you look at the computer strangely, the CGI script won't work.
  • We'll continue with The More CGI Lab today.
• Are there questions on homework 3?
  • I've dropped the Web part, given our in-class difficulties.
  • It really helps if you carefully document the purposes and parameters of your procedures before you write (or at least before you use) those procedures. Example: findPerson.
  • It really helps if you choose reasonable names for your procedures and parameters.
  • The datees.ss file is available. Once you make a copy, you can include it in your program with

    (load "datees.ss")
    

Overview

What? Do you really think that I have my notes on Pause for Breath prepared this far in advance of the class?
