Prerequisites

You must be able to program in C or C++. If you can't, you should seriously consider dropping this class.

You should have a decent knowledge of computer architecture. Operating Systems (W4118) and Introduction to Cryptography (W4261) are helpful but not required.

Homework Policy

There will be four or five homework assignments, each consisting of a written part (30%) and a programming part (70%).

Unless otherwise instructed, all homeworks must be written in C or C++. Java is not acceptable; don't bother asking.

Late assignments are subject to increasing penalties. There are no grace days or "free lates". See the slides from the first class for details.

Grading

Homeworks 50%
Midterm 20%
Final 30%
The percentages will be adjusted slightly if there are only four homework assignments.

All exams are open book. This means that there won't be any "define Foo" questions. Most questions will ask you to think and to integrate material from different lectures.

Final grades are curved.

The tentative date for the midterm is Tuesday, October 21. The final exam will be at the date and time scheduled for this class by the registrar.

Courseworks

Unless there is significant sentiment to the contrary, I will not use Courseworks except for the gradebook and the discussion list. All lectures and homework assignments will be posted on this web site.
