Szumlanski is honestly one of THE best professors out there. His course is tough for beginners in programming, but goes through the content thoroughly and adds lecture notes usually after class. In lectures, he explains the content through code demonstrations (which you can follow) and provides source code in his lecture notes. He has 6 programming assignments across the year and 3 tests (including the final). He bans the use of IDEs and requires you to compile using gcc in a linux shell (it sounds bad at first, but you learn a lot more from it), essentially giving you experience using linux (using commands like scp, cat, diff, vim, ssh, output redirects, and piping).

Attend his or his TA's office hours, and do the practice problems and labs he provides! Most importantly, practice programming weekly.
