This is the reason the VM was introduced. So that no matter what OS the user is running, they can follow along without having to go search for ways to get all this setup and running. The setup is very minimal thanks to Chef and Vagrant.

Kenneth is trying to teach best practices and tools to use. He also explained in the beginning of the video that you should be comfortable with a terminal and text editor that you like. This shouldn't be your first time looking at a terminal.

Heroku is a simple way to get your project out to the public and it's free. Nothing inspired me more as a developer than having others look at my work. I think it adds a little bit of excitement to be able to show your work to others almost immediately. Even if it's something small, it's still something to "show off" and feel good about.

You're right. That was an oversight on our side and we've corrected it. Thanks.

I did not know this existed, I'll have to give it a look. The setup method makes sense, not sure I like having to check is_valid() though.
