First class: Friday 8 January
Important Note: Please try
to send
all course material from a
University of Waterloo account (ie., SSH into a teaching or
research machine and send from there). If you don't have a
Waterloo account yet, please contact the MFCF help
center (MC3011). In the meantime you can use the account you gave
in the first class. Also please don't send any
messages with "zip" or "gif" attachments (send "tif" or "jpg" instead,
or refer me to a URL). Those are common filetypes in Microsoft
viruses and are removed by my SPAM filter.
