It doesn’t scare me, I was just wondering if there was ever a need for just plain old users of computers, or even someone like me who is an old mainframe person, what it might be used for if we were not PC oriented. I mean I know PC’s better than most perhaps but I was trying to figure out how I might use the knowledge. 8>)
The mainframe is back, sort of, but it's called the cloud now. You'd use ssh to connect to the cloud server's Linux command prompt, and it's also the gold standard for secure file transfers. It's not flashy software but it's stable and high quality with very few bugs. It's a must learn for cloud computing.
Reading between the lines I kind of thought that was the case. I could see a use for securely sharing large files between two computers over a wireless network?
