I remember installing Mandrake Linux on my PC (via CD ordered online as magazines still hadn't started to include the CDs). I had the dial-up line and the modem but didn't know how to set it up as I was new to both Linux and dial-up. So I used to print the steps from websites/mail groups at office to try them at home. Initially I couldn't make it work and had no choice but to wait to get to office the next day to start again.

Finally I read a bunch of docs about how to talk to the modem and eventually I managed to do the correct steps and the modem produced its sweet handshake tone and the indicator lights started to blink - it was such a pure joy to finally be online from Linux!

That instant was unique for human-tech interaction. Perhaps comparable with becoming positively viral, but at small scale.
