Most data compression methods that are based on variable-length codes employ the Huffman or Golomb codes. However, there are a large number of less-known codes that have useful properties - such as those containing certain bit patterns, or those that are robust - and these can be useful. This book brings this large set of codes to the attention of workers in the field and to students of computer science.
David Salomons clear style of writing and presentation, which has been familiar to readers for many years now, allows easy access to this topic. This comprehensive text offers readers a detailed, reader-friendly description of the variable length codes used in the field of data compression. Readers are only required to have a general familiarity with computer methods and essentially an understanding of the representation of data in bits and files.

Topics and Features:
Discusses codes in-depth, not the compression algorithms, which are readily available in many books
Includes detailed illustrations, providing readers with a deeper and broader understanding of the topic
Provides a supplementary author-maintained website, with errata and auxiliary material www.davidsalomon.name/VLCadvertis/VLC.html
Easily understood and used by computer science majors requiring only a minimum of mathematics
Can easily be used as a main or auxiliary textbook for courses on algebraic codes or data compression and protection
An ideal companion volume to David Salomons fourth edition of Data Compression: The Complete Reference

Computer scientists, electrical engineers and students majoring in computer science or electrical engineering will find this volume a valuable resource, as will those readers in various physical sciences and mathematics.
David Salomon is a professor emeritus of Computer Science at California State University, Northridge. He has authored numerous articles and books, including Coding for Data and Computer Communications, Guide to Data Compression Methods, Data Privacy and Security, Computer Graphics and Geometric Modeling, Foundations of Computer Security, and Transformations and Projections in Computer Graphics.

Although Web usability has received lots of hype, especially during the dot-com meltdown, the focus has been mostly on technical issues. Usability experts stress the pitfalls of frames and too many images on Web pages. They recommend editing out unnecessary words and writing in a non-linear style-all valuable advice, of course. But less frequently do they highlight the importance of the visual presentation of Web pages. The Web is a communication medium that does most of its talking visually. What you see on a Web page tells you what you might find within the site, how to get there, and why it might interest you-not to mention the instinctive emotional response that shapes your Web experience. As a result, Web usability issues are communication issues. Easy-to-use sites are those that communicate quickly and effectively.

Site-Seeing takes a fresh approach to Web usability by applying visual communication principles and decision-making to Web design. Specifically, readers will learn the key concepts behind visual organization, look and feel, technical considerations, and clear planning that stem from audience awareness. Through numerous, full-color examples author Luke Wroblewski deconstructs “the good, the bad, and the ugly” of Web design.

The visual presentation of a site does more than merely making it pretty. It organizes information according to function. It creates distinct and appropriate personalities. It provides emotional impact and attachment. In short, it engages the audience-and keeps them coming back.
