Read Ammon Shea's blogs and other content on the Penguin Community. A surprising, lively, and rich history of that ubiquitous doorstop that most of us take for granted. Ammon Shea is not your typical thirtysomething book enthusiast. After reading the Oxford English Dictionary from cover to cover (and living to write about it in Reading the OED), what classic, familiar, but little-read book would he turn to next? Yes, the phone book. With his signature combination of humor, curiosity, and passion for combing the dustbins of history, Shea offers readers a guided tour into the surprising, strange, and often hilarious history of the humble phone book. From the first printed version in 1878 (it had fifty listings and no numbers) to the phone book's role in presidential elections, Supreme Court rulings, Senate filibusters, abstract art, subversive poetry, circus sideshows, criminal investigations, mental-health diagnoses, and much more, this surprising volume reveals a rich and colorful story that has never been told-until now.

The book has an introductory chapter that gets the reader started quickly with programming in Perl. The initial part of the book discusses Perl expressions, statements, control flow, built-in data types such as arrays and hashes, and complex data structures built using references. On Perl has several chapters covering specialized topics. The chapter on socket-based network programming deals with forking and using fork to write complex interactive client-server programs. There is a chapter with in-depth discussion of CGI programming including error-handling and security issues that arise. The chapter on web-client programming deals with writing programs that access Web pages, fill up GET and POST forms, handle cookies and redirected Web pages. The book has several unique chapters not found in any other book on Perl in the market. The chapter on security discusses hashes such as MD5, message authentication codes (MACs), digital signature schemes, and encryption techniques such as DES, Rijndael, and RSA. Other chapters deal with writing recursive programs that work with files and directories; this chapter also discusses predefined modules that deal with portability in file names and paths across operating systems, recursive traversal of file hierarchies and tarring and untarring of filles. The chapter on functional programming illustrates that Perl functions are first-class, can be used to write closures and can be composed to form more complex functions. In particular, this can be useful for programming in artificial intelligence.

Guidance to help you grasp even the most complex network structures and signaling protocols The Second Edition of Signaling in Telecommunication Networks has been thoroughly updated, offering new chapters and sections that cover the most recent developments in signaling systems and procedures. This acclaimed book covers subscriber and network signaling in both fixed and mobile networks. Coverage begins with an introduction to circuit-switched telephone networks, including an examination of trunks, exchanges, access systems, transmission systems, and other basic components. Next, the authors introduce signaling concepts, beginning with older Channel Associated Signaling (CAS) systems and progressing to today's Common Channel Signaling (CCS) systems. The book then examines packet networks and their use in transmitting voice (VoIP), TCP/IP protocols, VoIP signaling protocols, and ATM protocols. Throughout the book, the authors emphasize functionality, particularly the roles of individual protocols and how they fit in network architectures, helping readers grasp even the most complex network structures and signaling protocols. Highlights of the Second Edition include: Coverage of the latest developments and topics, including new chapters on access networks, intelligent network application part, signaling for voice communication in packet networks, and ATM signaling Drawings and tables that help readers understand and visualize complex systems Comprehensive, updated references for further study Examples to help readers make the bridge from theory to application With the continued growth and expansion of the telecommunications industry, the Second Edition is essential reading for telecommunications students as well as anyone involved in this dynamic industry needing a solid understanding of the different signaling systems and how they work. Moreover, the book helps readers wade through the voluminous and complex technical standards by providing the essential structure, terminology, and functionality needed to understand them.
