I think the biggest advantage of this course is that it's helpful whether you're a beginner or already a developer. In my case, I had studied Ubuntu before and it was the operating system I mainly used for development, so I was familiar with it, but it was great to be reminded of parts I had forgotten. And so far, it's working fine on Windows WSL without any problems, so I think beginners could also do the practice sessions on WSL if they don't have a Mac. I can't guarantee what happens later though..😊😊 I think it would probably be very helpful for beginners if they encounter problems in this area and want to work through solving them. Lastly, I haven't heard much about Docker yet, but for someone like me who only had a shallow understanding that Docker is a tool for managing containers, this is becoming a time where it really hits home. Thank you.
