It's a well-known book but I find it very impressive just how meticulous the author has been over the years. Another author who is similar in attitude is Donald Knuth. Of course most the errata comes from readers but still. Like battle scars, it makes the book even more impressive.

This one by Evil Martians is fairly recent https://rails-tutorial.evilmartians.io/ I haven't done it, since I already know Rails very well, but I know these guys as reputable contributors to the Ruby ecosystem.

It’s the official new Getting Started but ported to a browser-based runtime powered by WebContainers, so you can complete the whole tutorial without having to install Ruby or Rails. It’s very cool!

Cool recomm. I’ll check it out - web containers seems like a poor idea for a development course but I suppose it removes setup complexity.
