After listening to the free introductory lecture, I started listening to it right away. I have been developing desktop apps based on EclipseRCP so far, so I was at a loss about changing jobs. So I heard about the lecture through a friend's recommendation, and I started listening to it to build a backend technology stack. The lecture was easy to understand, and I was able to quickly finish it because I thought about the practical stories in the middle. I also wrote about HTTP because the reviews were helpful before I continued listening. Thank you for the lecture!
