CSC151 2009F, Class 16: Anonymous Procedures

Admin:
* EXAM ONE DUE!  NOW!
  * In the future, please do not hand in the printed copy of your exam 
    until the day it is due.  (Sam gets distracted.)
  * We had at least one student lose work because MediaScheme crashed 
    while they were working.  Your generation should know to 
    "SAVE EARLY AND OFTEN"
  * In spite of my making jokes about errors creeping in to the labs and
    readings because I write them at 2 a.m., I do not recommend finishing
    your exam at 2 a.m.
  * We will go over the exam on Monday.
  * It made me happy to hear how one set of students was discussing the
    exam.  (That is, using the exact quote from the front page.)
* EC, Friday, Oct 2. noon: 
    "A Historical View of the Early Development of Programming Languages" 
  * Free pizza.  
  * We need an approximate head count (10).  Is anyone interested in coming?  
* Reading for Friday: Turtle Graphics.  
  * Yes, we're starting yet another perspective on images.  
  * We'll count how many we have so far.
* The next assignment should be ready tomorrow afternoon.  
  Sorry for the delay.  
* No introductory lecture today!  
  * If you haven't done the (short) reading, you may want to do so
    at the beginning of lab
