This thoroughly updated edition of The Scheme Programming Language provides an introduction to Scheme and a definitive reference for standard Scheme, presented in a clear and concise manner. Written for professionals and students with some prior programming experience, it begins by leading the programmer gently through the basics of Scheme and continues with an introduction to some of the more advanced features of the language. Many exercises are presented to help reinforce the lessons learned, and answers to the exercises are given in a new appendix. Most of the remaining chapters are dedicated to the reference material, which describes in detail the standard features of Scheme included in the Revised Report on Scheme and the ANSI/IEEE standard for Scheme. Numerous examples are presented throughout the introductory and reference portions of the text, and a unique set of extended example programs and applications, with additional exercises, are presented in the final chapter. Reinforcing the book's utility as a reference text are appendixes that present the formal syntax of Scheme, a summary of standard forms and procedures, and a bibliography of Scheme resources. The Scheme Programming Language stands alone as an introduction to and essential reference for Scheme programmers. It is also useful as a supplementary text for any course that uses Scheme. The Scheme Programming Language is illustrated by artist Jean-Pierre Hebert, who writes Scheme programs to extend his ability to create sophisticated works of digital art.

本書檢視駭客的世界，以及駭客活動背後的動機。在這個日漸電腦化的世界裡，駭客是個帶有多重意義的名詞，它對創意使用者帶來尊崇，也對規矩破壞者帶來鄙視意味。Paul Graham 的散文引領讀者瀏覽他筆下的駭客世界，一個聰明才智泛流的新荒野。 為什麼一個唸不完高中的孩子，最後卻晉身為世上最有權勢的人？科技是否將建立出新的鴻溝，一端是懂得使用科技的人，一端是不會使用的人？微軟是否將接掌網際網路？我們該拿垃圾郵件怎麼辦？這些都是本書討論的議題。 如果你想瞭解駭客心理在想什麼，這本書可以回答你的問題。如果你已經是個駭客，或許，你能從這本散文集中發現自己的身影。

This book is about learning to program in Lisp. Although widely known as the principal language of artificial intelligence research—one of the most advanced areas of computer science—Lisp is an excellent language for beginners. It is increasingly the language of choice in introductory programming courses due to its friendly, interactive environment, rich data structures, and powerful software tools that even a novice can master in short order. When I wrote the book I had three types of reader in mind. I would like to address each in turn. · Students taking their first programming course. The student could be from any discipline, from computer science to the humanities. For you, let me stress the word gentle in the title. I assume no prior mathematical background beyond arithmetic. Even if you don’t like math, you may find you enjoy computer programming. I’ve avoided technical jargon, and there are lots of examples. Also you will find plenty of exercises interspersed with the text, and the answers to all of them are included in Appendix C. · Psychologists, linguists, computer scientists, and other persons interested in Artificial Intelligence. As you begin your inquiry into AI, you will see that almost all research in this field is carried out in Lisp. Most Lisp texts are written exclusively for computer science majors, but I have gone to great effort to make this book accessible to everyone. It can be your doorway to the technical literature of AI, as well as a quick introduction to its central tool. · Computer hobbyists. Prior to about 1984, the Lisps available on personal computers weren’t very good due to the small memories of the early machines. Today’s personal computers often come with several megabytes of RAM and a hard disk as standard equipment. They run full implementations of the Common Lisp standard, and provide the same high-quality tools as the Lisps in university and industrial research labs. The ‘‘Lisp Toolkit’’ sections of this book will introduce you to the advanced features of the Common Lisp programming environment that have made the language such a productive tool for rapid prototyping and AI programming. This current volume of the ‘‘gentle introduction’’ uses Common Lisp throughout. Lisp has been changing continuously since its invention 30 years ago. In the past, not only were the Lisp dialects on different machines incompatible, but programs written in one dialect would often no longer run in that same dialect a few years later, because the language had evolved out from under them. Rapid, unconstrained evolution was beneficial in the early days, but demand for a standard eventually grew, so Common Lisp was created. At present, Common Lisp is the de facto standard supported by all major computer manufacturers. It is currently undergoing refinement into an official standard. But Lisp will continue to evolve nonetheless, and the standard will be updated periodically to reflect new contributions people have made to the language. Perhaps one of those contributors will be you.
