interestingly, soda.csua.bekeley.edu had logging by 1993. and the mechanism? a complete rewrite of wall as the redundantly named wallall, which wrote to a log file right after it wrote to all the ttys. that way there was no need to snarf a pty just to log.
and by the way, i don't agree that it's ok to log any public stream just because it's public. some public media don't feel like a medium of record, and invite an informal behavior that their users would regret if they knew they were being logged. if i knew everything i'd say in public could be held against me forever, i'd say very different things.
Wasn't there something with the username of the log file being named after Larry Wall? Or the account that you finger to read it? Because his last name was also Wall?
... although he actually did study at UC Berkeley at one point, so maybe the plot was somehow thicker than I realized.
