Its a bit funny to ask this question in this thread, but here we go: What are the important topics & technologies to learn about with these types of topics? My uni experience didn't really include things like distributed systems or containerization. Ideally fundamentals that won't be invalidated in 5 years when 'the new thing' becomes something else. (Love good book recommendations on any subject a new grad should learn, not just this topic)
