Guest lectures in Advanced/Accelerated Computer Systems (in this folder)

[ NOTE THAT TWO of the GUEST LECTURES include AN OPTIONAL EXTRA CREDIT
  HOMEWORK (*-apr-10-hw.docx and *-apr-14-hw.txt, below).
  As discussed in class, if you do one of the two extra credit assignments,
  it will be added to your raw cumulative course score.
  The homeworks are 20% of your course grade.  So, one extra credit hw
  adds 20%/8 = 2.5% extra credit to your course raw score.
  If you do a second extra credit hw, that score will replace the lowest
  score of your current homework grades.

  Any extra credit hw must be submitted by the end of Thurs. April 23.
  I may choose to orally quiz you on your extra credit homework submission
  after the final exam, to ensure that the work is truly your own.
  (If time permitted, I would quiz everybody.  Asking you to submit to
   an oral quiz does _not_ mean that I suspect you of cheating.)

  Also, please note that /course/cs4973/homework
  has two scripts to submit the extra credit:
    submit-cs4973-hw-extra1
    submit-cs4973-hw-extra2
  Use extra1 for the first optional exttra credit.  Use extra2 only if you
    are submitting two optional extra credit assignments.
  And please add a README.txt file to explain what you are submitting,
    and which extra credit it is, and how it fits with any files that
    were given.
