I have reached the same stage and am unable to continue doing the course online. Is buying the book the only option? It seems strange to me as the home page of the website says that "The site contains all the software tools and project materials necessary ..." and "Everything is free and open-source"
Both editions are pre-orders and the earliest I can get it is December 2020?!
It's really not fair to not put this upfront, that we can only do half the project then wait half a year before being allowed to pay to do the rest.
Does anyone have a link to another version? I'm not paying $70 on US Amazon
That is the second edition. Everything on the website (and here on the forums) is for the first edition.
You want the first edition (unless you would like to wait and do everything from the second edition -- I don't know what the plans and timetable might be for making materials such as the planned revised software suite available online).
