Well, this tutorial isn’t necessarily for NOOBs. Note the preceding sentence, “Our first Teapot application will be a fairly extensive login management front end.”
This is a substantial and nontrivial application intended for people who are already familiar with Pharo. I could’ve chosen a much simpler application, but then you wouldn’t learn very much at all. This application has a lot of meat to it, and you will learn a lot. That makes it quite useful, which was my aim.
Any application worth doing requires work. It requires commitment. Nobody is going to hand you such an application on a silver platter.
If a NOOB never pushes themselves beyond the basics, they will never advance beyond being a NOOB.
