Most of the book is available for free on• It is by far the best for achieving the goals of the book, to present biomedical informatics as a systematic set of formal ideas and methods that are naturally expressed as computations on well-defined representations. Presents the concepts of object-oriented programming and incorporates the Common Lisp Object-Oriented Systems CLOS of the new ANSI standard. Next you'll see "how Chris Pine would do it": answers using more advanced Ruby techniques, to whet your appetite as well as providing sort of a "Rosetta Stone" for more elegant solutions. Lisp的语法非常简单,这是它区别于其他语言很重要的特点。 cons cells:指LIsp中的所有括号包围着的符号,数字,字符串。 Semantic Web语义网的很多工具也是用Lisp开发的,如 RacerPro, AllegroGraph 那为什么Lisp会给人一种已经死去的感觉呢?人们判断一个事物的价值一般通过三种没有科学根据的条件: 1. The site features a music video, and a comics strip. Those dark days are finally over— Land of Lisp brings the power of functional programming to the people! The name for the style of pro- gramming that relies heavily on passing functions as values is called higher-order functional programming. You are an amazing person, however, for releasing all of your hard work for anyone to learn from! Emacs Lisp is kind of a crappy Lisp dialect, but it's a very accessible way to learn the basics, and if you use Emacs, quite immediately useful.

(在Common Lisp 中许多的函数都有一种内建的功能,就是可以在参数列表的最后给他们传递一个特别的参数)如: find 'x ' x 1 y 2 z 3 :key 'car return: x 1 后面的:key参数像一个谓词函数,他先执行返回的结果再被find函数要来查找 item,最后返回找到item的原始item。 It is also the first Common Lisp book to tackle such advanced topics as environment access, logical pathnames, Gray streams, delivery of executables, pretty printing, setf expansions, or changing the syntax of Common Lisp.

Book Summary: Paradigms of AI Programming is the first text to teach advanced Common Lisp techniques in the context of building major AI systems. This would appeal to students who sat through a LISP course in college without quite getting it — so a "nostalgia" approach, as in "wow-lisp can be practical.
