The lecture on Tuesday will be delivered by 
Mr. Stylianos Paparizos, a graduate student in
our College on a Fullbright scholarship from Greece. 
He is your teaching assistant from now on and he comes
from the land of Demeter (the Greek Goddess of Agriculture :-).
He will cover DJ, both the theory and the API of DJ.

If you have questions about the course material, please send
email to stelios@ccs.neu.edu.

Mr. Paparizos has a mailbox in 161 and he also holds
a weekly office hour in 53 CN from 5.30 to 6.30 pm on Tuesdays.

I have to go on an urgent trip and will be back for class on Thursday.
If you have difficulty in running DJ, please send email to
Doug Orleans who knows the theory and the library very well.
He is the implementor of DemeterJ and much of DJ and a PhD
student in our College.
