29:09 Why are you iterating through the list if you can just call list.remove(observer) immediately? Since you're passing through the observer and not li.
Great series! Learned a lot! Can you please share the code? Thanks!!
Mike, this whole series has been incredibly relevant to me for a project I'm currently working on, and your explanation has dramatically enhanced my understanding. I find your explanations to be some of the best on YouTube and I don't understand how you're not getting more views. I'll certainly continue to watch!
Great. Planning to continue OpenGL series?
