The ACM Digital Library is a great resource for all things computing, but they also have a publication called XRDS: Crossroads which is the ACM magazine for students. Each issue centers around a theme and includes articles, interviews, and even career advice for computer science students.
Also, the library now has O'Reilly for Higher Education. In it you can find a digital copy of your textbook, as well as additional books, videos, and courses to supplement your class learning. If you need help with Python, Java, or other programming languages, they have resources just for you.
