Learn X in Y minutes Where X=clojure
From the post:
Get the code: learnclojure.clj
Clojure is a Lisp family language developed for the Java Virtual Machine. It has a much stronger emphasis on pure functional programming than Common Lisp, but includes several STM utilities to handle state as it comes up.
This combination allows it to handle concurrent processing very simply, and often automatically.
The post concedes this is just enough to get you started but also has good references to more materials.
Useful for the holidays. Like playing chess without a board, you can imagine coding without a computer. Could improve your memory. 😉
