In college nobody knows if you really do pull an all nighter
If you were a cs student in 1995, you pretty much had to work in one of the basement labs. One of the profs liked to come to the lab at 3am before a deadline and laugh at us.
Also we didn't really have many people with laptops, so if you had a group project meeting in the lab was pretty much the only way you could all get computers but still interact with each other.
The social aspects of the old labs made for many memories and lessons.
