If you want to get more technical, lean in to the Electrical Engineering department and find some courses there. You'll learn a lot about the underlying hardware and logic that your programming is interfacing with.

If you want to learn about applying your skills more successfully, look into an area where you think you'll be working. Most people don't graduate with a CS degree and start working on compilers. I worked at a network vendor where we made firewalls/routers, a lot of our programmers didn't have a clue how customers implemented our products in the real world. In that case, taking networking and security courses would be beneficial.
