Howard is an incredible professor. I would highly recommend taking a class with him if you have the chance.
He is incredibly knowledgeable and a great lecturer. For the entirety of each two hour lecture, I found myself completely engaged throughout. I learned the concepts thoroughly through his lectures. He has a way of teaching that allowed me to fully understand these concepts. I wasn't just learning what code to write down, but I was learning about how the program actually words and why we need to tell the computer something in a certain way. I was able to develop a deep understanding of these concepts. This made my life infinitely easier when it was time for exams, because I didn't actually feel the need to study a lot. I already knew the concepts so well that all it took was a review before I felt confident. He also allowed us to have cheat sheets for the exams which helped a lot.
The projects will be tough, especially the last few. It cannot be emphasized enough that you can't start a project too early. Just do yourself a favor and start the project the day it gets assigned. You won't regret it.
Howard's office hours were always extremely helpful, and he will take time to answer your question or look at your code one-on-one.
I remember Howard introducing himself on the first day of lecture as "human". And he definitely is. He's easily approachable, and he will be understanding if you are going through something. He will take time to explain a tricky concept or answer your question.
This class is by no means easy. You will have to put in a lot of time and effort. But if you are hardworking and stay on top of the work, you can be very successful in Howard's class.
My advice for a successful quarter: go to every lecture in person, start the projects when they're assigned, and go to office hours.
