I discovered the series earlier today on HN and the discovery could not have been any timely-er. I am just about to embark on the first six to eight months of a learning journey and see immediate utility in insightful series such as this one.
I also came across a really helpful post that gives recommendations on progress markers for the self-taught developer [A Better Way to Learn Programming? Notes on The Odin Project;http://everydayutilitarian.com/essays/notes-on-the-odin-proj...]. Guides like these, while they take a lot of time to write and refine, are complete lifesavers for entry-level professionals and prospective practitioners (and especially if they come from professionals that have been "tried and tested").
