Sorry to interrupt you, but if you are reading HN while sitting on your lectures, why not just go home and get some sleep?

Sometimes the only reason you go to lecture is to be sure to catch important announcements. You can to that with little sleep, and in the meantime, you need something low-effort to keep you awake. So there's one theory.

Or you can buy a beer once a week to someone that will send you "important announcements" by email, and having a good solid sleep in own bed ;)
