I know some Lisp/Scheme, but never really did any projects in it. What did you use to learn Racket (both the language and the ecosystem)? If I had to read a single book/tutorial, what will give me the most bang for my time? I tried reading the official docs, but while they're great for reference, probably not the best in terms of tutorials/learning.
