From blogs, conferences, meetups or on the job. Also, universities have traditionally been terrible at teaching those concepts. I haven't worked with CS graduates for a few years, but usually they were terrible at designing anything, totally misunderstood OOP, etc. Because lecturers were terrible at teaching it, often because lecturers had no experience actually programming professionally. Maybe it's changed now. For example lecturers loved talking about polymorphism, even though you almost never should use it. I remember a project I inherited from a graduate where he'd gone absolutely crazy on inheritance, where an industry professional would have used just a select few interfaces. Nightmare code.
