Inform them that you've put the answer key to their upcoming final exam on a poorly secured EC2 instance or s3 bucket. This technique serves a variety of students in different ways. Those who have no idea what you mean get a valuable introduction to independent study. Those who have the chops might up their game enough to crack it. Those who are rich enough to hire a smart kid to do it for them impart a valuable lesson to the group on the nature of privilege. Those who are neither smart nor rich are incentivized to stay in school. To top it off, make the final exam consist of thought provoking essay questions whose answer key takes the form of detailed notes and citations.
