I really enjoyed the lecture! I was using logback and @Sl4jf without fully understanding them, but now I've learned about their concepts! However, this lecture didn't just stop at simple principles or knowledge; it allowed me to process logs, and if one has experience handling logs for purposes like CS response, there were many points that resonated deeply. Thus, I found myself nodding along throughout the lecture. In any case, it was incredibly helpful, and I hope you'll create lectures on a wider variety of topics 😊😊 (Or, lectures that integrate various technologies or cover an entire specific domain would be even better.)
