Libro: Computación y programación funcional

This looks on topic, but post that are not in English are usually ignored or flagged. At least translate the title here. Something like "Book: Informatics and functional programing [Spanish]"

For blog post I recommend to translate them and post the translated version. For a book, that's probably too much work. (Anyway, the English version of the book may get more buyers.)

Edit: And definitively translate your comments here.

A book about lambda calculus and functional programming using Racket and Python.
