Interesting quote from the author:

While I consider Java to be twice as "programmer efficient" as C++, I consider Common Lisp to be twice as good as Java for some applications.

Practical ... in Java

That's an oxymoron.

How is commercial use defined in terms of the book? It's not that free. Then again, if you use an algorithm for something at work, it does makes sense to reimburse the author. I just thought I should point it out.

Looks interesting. Thanks for sharing.

Just checked the content. It is a "modern" book despite some old stuff in neural network, generic algorithm and expert system. It is a book mainly about natural language process with a bigger title "artificial intelligence" which should be carefully avoid in today's word.

Nice article
