I'm a nuclear engineer and I noticed that there was no official venue where people were learning the particular computer basics that I consider essential for daily operation of a computer as an engineering tool.
I figured maybe other fields have the issue too and I got it together enough to out out my first and only ebook on the topic. It's higher level than OP here, but still focuses mostly on the command line. Anyway, it's called Digital Superpowers and is $10. If anyone wants a preview chapter or anything I can send you one.
