Has anyone used the “Land of Lisp” book, or Exercism.org to learn Common Lisp? Any other fun alternatives for learning lisp?
Land of Lisp is fun, and the video is a must![0]; I also really like Norvig's PAIP (Paradigms of Artificial Intelligence Programming, available for free now on GitHub[1]). PAIP shows ways of programming in Lisp that really are unlike what I've seen in most other languages.
Lately I have been working the Exercism exercises and there are over 80 Common Lisp problems, with more problems being added over time (my hope is to finish what's there and then help by adding some more).
