Aho, one of the authors of the dragon books. When I studied CS 40 years ago it was given standard literature on compiler construction, a mandatory course.
No idea whether it is still used today. Well, no idea whether there is anything fundamentally new in compilers such an old book would not cover.
There are plenty of advanced compiler techniques, but you can't understand them until you understand the fundamentals. There will always be a place for the purple dragon book.
