There are a few more that I cannot think of, but it is all mostly SYSPROG stuff.
If anyone has a specific systems topic that they are interested please let me know and I will do my best. I am retired and have more free time than I know what to do with.
My neighbors have always noticed that I would rather help them with their chores than to do my own.
I figure that I became a Senior Sysprog when I ran out of people that could answer my questions. Only two of them are still alive.
