Right, and I agree everyone has gaps in their knowledge. People obviously specialize and I wouldn't ever work on compilers, for example. I'm just describing what I often see the self-taught "millennial" programmer is missing with a minimal number of data points. Doesn't mean all of them do, but hopefully by me listing it here a book such as the above can tackle these topics. I hope somebody reading this doesn't take offense of my laundry list; it's just intended to show what I think would be useful to cover in such a book given their importance to app development. I'm no way knocking self-taught programmers. They learn a lot faster than those who went the formally trained route. One of my interns who was trying to get a master degree in CS I showed how to link to a library 3-times, and he still couldn't get it.
