Albert Sweigart (but you can call him Al), is a software developer in San Francisco, California who enjoys bicycling, reading, volunteering, computer security, haunting coffee shops, and making useful software.

He is originally from Houston, Texas. He finally put his University of Texas at Austin computer science degree in a frame. He laughs out loud when watching park squirrels, and people think he's a simpleton.

Al has written two books, "Invent Your Own Computer Games with Python" and "Making Games with Python & Pygame".

His web site and blog are located at http://coffeeghost.net

This article should acquaint you with basic Arduino programming and show you how to write programs that interact with objects in the real world.

This document is not intended to be a complete reference for shell scripting, as such a subject could fill entire libraries.

6.00 Introduction to Computer Science and Programming

This is an attempt to create a 'do it yourself' course in Unix and CLIX. The course will use CLIX rather than the command line (Terminal.app).

Wizard Book n. Hal Abelson's, Jerry Sussman's and Julie Sussman's Structure and Interpretation of Computer Programs (MIT Press, 1984; ISBN 0-262-01077-1), an excellent computer science text used in introductory courses at MIT. So called because of the wizard on the jacket. One of the bibles of the LISP/Scheme world. Also, less commonly, known as the Purple Book.

This site is a companion to the influential computer-science text Structure and Interpretation of Computer Programs, by Abelson, Sussman, and Sussman. Its purpose is to demonstrate the Web's potential to be a channel for innovative support for textbook users.

The material on this site is aimed at instructors using SICP as a course text, and at people using the book for self-study.
