I prefer to answer questions by e-mail. So try sending me mail first. If we cannot resolve the doubts by mail, we can meet during my office hours or fix an appointment.
I'll be posting answers to FAQ on homeworks and programming exercises here as needed. So please check this page before sending me mail. Thanks.
We are posting FAQ on the course wiki. Please check there to see if your question has been answered.
Languages I can probably help with, but no guarantees: Java, Visual Basic, Fortran
