I think it was about 1995. I was going to the university and was looking for something Unix compatible I could use at my home computer to perform assignments instead of needing to go into school computer lab. Remote work basically. Think I was using LessTif instead of Motif for some coding task.
Ahh. Those were the days. Used modem to connect to school and connect remotely to the network using Linux. :)
Don’t worry too much about it if it doesn’t make sense to you. It can be really valuable if you’re deploying a substantial amount of IoT devices on the edge with no to little possibility to do over the air upgrades reliably or when the cost of failure is high (i.e. a technician has to be on site to fix it). So, sometimes you just want it to be running as stable as possible for as long as possible without management.
