You need two textbooks, and one smart card:
(1) Problem Solving and Program Design in C, 4th Edition or 5th Edition,
Jeri B. Hanly, and Elliot B. Koffman
4th Edition: ISBN-10: 0321198034, ISBN-13: 9780321198037, Addison-Wesley, 2004
5th Edition: ISBN-10: 0321409914, ISBN-13: 9780321409911, Addison-Wesley, 2007
Either edition is fine.
(2) Either Just Enough Unix, 5th Edition or Visual QuickStart Guide: Unix, 3rd Edition
If you already purchased Just Enough Unix from a previous class, there is no need to purchase an additional book. If you have not already bought a book, the Visual Quickstart Guide is less expensive, and presents the same material, but it is organized more clearly, and is probably a better match for the needs of this course.
(2a)Just Enough Unix, 5th Edition, Paul K. Andersen.
ISBN: 0-07-295297-0 McGraw-Hill, 2006
Either the 5th edition (shown) or the 4th edition (not shown) will do. You can get online access to the 5th edition for around $36, a lot cheaper than buying a paper book. See http://ebooks.primisonline.com Click on "McGraw-Hill Ebooks", then "Next", then "Science Engineering and Math", then "Computer Science". It will be the first book on the list.
(2b) Visual QuickStart Guide: Unix, 3rd Edition , Deborah S. Ray and Eric J. Ray
ISBN: 0-321-44245-8, PeachPit Press, 2007
List price for print copies of this book is $24.99—about 1/3 the list price of the Andersen book—yet this book is organized more clearly, and more of the book is relevant for the purposes of this course. An electronic copy is also available from PeachPit press for $17.99.
(3) Smart Card for Sun Rays (available at bookstores that sell UD textbooks for around $6-7). You need this for efficient access to the Sun Ray terminals and for accessing your Sun Ray session during office hours. I'll say more about this in lecture.
