After listening to the lecture, my head feels clearer and something feels like it has lifted. It is amazing that the main concepts of ARM, which had been vague until then, have been clearly organized. I was a little surprised at how much I have changed after listening to the lecture. Every time I read the ARM spec, it felt new, but now I can read the ARM spec document fluently. I also recommended it to my fellow developers because the content was immediately applicable to my project. I am glad to have listened to the life lecture and I hope more lectures are uploaded. Thank you so much for the great and informative lecture.
