Cheating is taken very seriously in CS 241. Be sure to understand the departmental honor code. Your work in this class must be your own. If students are found to have cheated (e.g., by copying or sharing answers during an examination or sharing code for the project), all involved will receive grades of 0 for the first infraction and will be reported to the academic office, and may receive additional penalties such as a reduction of one letter grade in the final course grade. Further infractions will result in failure in the course and/or recommendation for dismissal from the university.
You are a respected individual in a community of collegiality and trust. We honor and believe your word. We trust what you say and will generally not ask for proof. However, with trust comes responsibility. Violation of trust will not be tolerated. In particular, acts not befitting this community such as cheating (e.g., collaboration on homeworks or exams that are not meant to be collaborative) fall in the category of violation of trust. Individuals who commit such acts will lose the privileges of trust and receive grade reductions as described above.
Your machine problems must be a result of individual work. You are responsible for protecting your work. In the past, we had cases of copying solutions from other students without their knowledge. To avoid having your work copied without your knowledge, refrain from leaving source code prints lying around the lab, protect your files, don't give your passwords to anyone, and enter your passwords in a way that cannot be seen by others. Do not leave a login session active on an unattended workstation. Use xlock on the CSIL workstations if you must leave briefly, or use some similar measure (or log out!) in other labs; remember that it's a violation of the CSIL policy (and probably the other lab policies) to leave your workstation unattended for any extended period of time. Report suspicious behavior to the lab sitters or the TAs.
