Please double check with Purdue's web site to make sure there's no last minute change to the schedule or room.
We use Piazza for announcements (including TA contact info), course materials discussions and lab/project posting.

Class Policies and Workload
Please see Week 1's lecture notes (posted below).
As announced in class,
a minor revision to the policy on cheating cases is posted here. Feb. 4th, 2013
As announced in class email and posted here,
a new penalty level will be implemented for all cheating cases for the rest of the semester, starting with Lab 4 and Midterm 1.
(Feb. 18th, 2013)
All exams are close-book and close-notes.
Virtual Machine for Labs/Projects
If students work on labs and projects on computers other than those in our designated lab, we require them to use
this image of VMWare that contains all
software, tools, and libraries that you will need for your assignments. (This is to avoid the potential problem that codes developed on other machines do not work on the ones used to grade them.) The login and password necessary to access this image will be provided in the labs. Students who do not already have VMWare installed on their personal machines can do so by downloading VMWare player; this is a free download. Another free alternative is Virtual Box (which works for Mac OS).
The following book is our required text:
The C Programming Language, 2nd Edition,
Brian W. Kernighan and Dennis M. Ritchie
