There are so many specialized areas that are useful, like common design patterns, basic data structures, various algorithms, transactions, multithreading, parallel processing, etc. Too many things to list, but I agree with a poster below that suggested looking at the course offerings for a computer science degree. You might be able to find outlines of the courses to get specific topics. On a day to day basis, code coverage is something that more people should use when writing unit tests to ensure they have tests that execute all their code.
