It was the best lecture I've ever seen. The PPT material was also very well made. I had a lot of trouble deciding whether to start web development with Django or Rails. The trend these days is Python, so let's do everything with Python! So I was going to start web development with Django, a Python web framework. The biggest problem while learning Django was that it was hard to track down the cause by myself when an error message appeared. I was curious about Rails, so I just skimmed through it, but thanks to that, I decided to go with Rails. Above all, it was easy to track down when a problem occurred. The beginner level content was enough. I wanted to move on to the intermediate level, so I bought both of the two Rails books (paper book, Insight e-book) that are available in Korea. If there are intermediate and advanced courses, I definitely plan on buying them.
