• Do not plagiarize on homeworks or projects — stated explicitly every year, and this year on video (15:45).
  • How they catch it: public GitHub repos from non-CMU followers are visible to the staff too, so those solutions get fed into Gradescope's plagiarism checker alongside student submissions (7:26, 15:45).
  • Extra deterrent: the instructor says he will take this recording's timestamp to Warner Hall as proof that students were warned, removing any excuse (15:45).
  • Side observation from the leaderboards: non-CMU submissions are generally not as good as CMU code, so copying them is a bad bet as well as a violation (7:26).
  • Applies to copying from friends and from random internet sources alike; if something is genuinely ambiguous, email the instructor first, and consult CMU's academic integrity policy (linked on the slide) (16:24).
