It's Monday already, even though I was writing a review on the weekend. I want to give it a good rating, but in fact, it wasn't a very informative class for me. I just quickly skimmed through the basics. Of course, I understand the instructor's difficulties. In a theory lecture without practical training, there are many references to prepare compared to the content that can be conveyed. How much data do you need to collect to accurately explain one simple concept? So, I guess the lecture ended up like this because I only extracted the content that could be conveyed clearly... I was reading and organizing the HTTP Complete Guide before taking this lecture (I'm still organizing it even after the lecture ended), so it wasn't worth more than reviewing some concepts. I think those who learned about networks in their undergraduate years or have some knowledge of HTTP don't need to take this lecture. Since lectures are a medium for conveying the instructor's experience, if there is an HTTP in-depth course or a network course, I would like to take it along with practical experience. For example, "Dissecting Tomcat"... In fact, I think what juniors find most difficult is the process of how the currently abstract concept is created and used concretely. I've used Tomcat too, but I don't know him very well, so I wish the lecture had included such content. I'm giving you two salt-flavored star candies to express my regret. I'm sorry if you were offended by the rating. I wanted to be honest about my regrets. I hope you can only leave good ratings for the next lecture.
