Let Over Lambda (ISBN 978-1-4357-1275-1, 376+iv pp.) is one of the most hardcore computer programming books out there. Starting with the fundamentals, it describes the most advanced features of the most advanced language: COMMON LISP. The point of this book is to expose you to ideas that you might otherwise never be exposed to. This book is about macros, that is programs that write programs. Macros are what make lisp the greatest programming language in the world. When used properly, macros enable amazing feats of abstraction, programmer productivity, and code efficiency and security that are unheard of elsewhere. Macros let you do things you simply cannot do in other languages.
Coq'Art is the familiar name for the first book on the Coq proof assistant and its underlying theory the Calculus of Inductive Constructions , written by Yves Bertot and Pierre Castéran. Interactive Theorem Proving and Program Development Coq'Art: The Calculus of Inductive Constructions Series: Texts in Theoretical Computer Science. An EATCS Series Bertot, Yves, Castéran, Pierre 2004, XXV, 469 p., Hardcover ISBN: 3-540-20854-2 This site has been updated for Coq8.2. Warning! Some solutions we propose don't work on versions prior to V8.2gamma. Please find here a tar file fully compatible with coq8.1pl3 and the printed edition of the book. These exercises were written after the release of the book (May 2004). The solution of some of them (e.g. mergesort ) illustrates new features of Coq. For instance, command Function and tactic functional induction.
