Built my first PC in 1982. Have used and worked on many platforms, not much on MACs. But a lot on DOS, Windows, Linux, IBM AS400, etc.
I’ m not a programmer, but have some experience with that.
Have been using various forms of Linux since 1994. My desktop PC runs Debian with XFCE GUI. Love XFCE, have been using it since Redhat 5.0 came out.
I once ran a catalog department for a wholesale distribution company. Lived in a spreadsheet and flipping from AS400 to Windows and Redhat Linux. It took all the tools of those to accomplish the scripted publishing. (Web & print- through Quark)
I will never go back to Windows, too many security issues.
The only names I recognize in what you wrote are DOS, Window, and Linux. Have zero experience with Linux, but at least I have heard of it.
My first PC for the home was a Tandy from Radio Shack. At work we had DOS and Lotus 123. All the computers at work were in a central location on our floor, and the Computer Techs took care of everything.
We just left our desk and went to an available computer in that room, brought up our spreadsheet etc. saved our updates to a floppy disk which we took back to our desk, after we printed out a report, if we needed hard copy.
Once a week the techs backed up all the data and stored it in a fireproof safe. Once a month the techs saved everything and sent it to 2 other remote locations in other states, where it could be operational within a few hours.
Since we always had computer techs on hand, I just never learned much about computers, other than using those programs and muddling through at home.
I have started using Modzilla Firefox for most things now, since internet explorer is just not working very well.
A strange thing to me, is that I have an icon for amazon.com at the bottom of my screen, and it will load faster, and better than either the internet explorer or modzilla. So sometimes, I just bring up Amazon.com by clicking that, and then change the internet address.
It’s weird to me.
