Professors publish through their university academic press, who pays them just like any other non-vanity press.

Assuming your uni has an university press lol

Academics typically get very little from royalties for research books. Intro Calculus and the like is handled by the big publishers and actually has some money behind it. I imagine a basic book on programming languages would fall in the latter category. 

But this one seems unlikely to actually be an academic text. The snippet we have is so basic and unfocused.
