I study math at uni and I was shocked realizing all my teachers use ubuntu on both their laptop and work desktop
Not only did my math master’s thesis adviser use Linux, he read his email from a command line program and wrote his papers in plain TeX, considering LaTeX a new fangled tool he didn’t need.
my whole university email server was accessed via telnet. So everyone used tty for email.
I think there may have been a gui or mail app that you coud point to it, but no one did. There was about a million(trillian?) gui’s people used for icq messaging though.
Wait what? Telnet? I am guessing cybersecurity is not one of the classes available at your school.
