A Nutshell handbook

This book describes the state of the internet, its basic components and protocols ranging from telnet, ftp and xterm to the www and early web browsers, as current in the early 1990ies. The author was at the time working at the University of Illinois - Urbana Champain (UIUC) which was instrumental in the development of the software architecture of the early modern internet. The book also contains a collection of websites, sorted by subject.

If you're just getting started with Perl, this is the book you want—whether you're a programmer, system administrator, or web hacker. Nicknamed "the Llama" by two generations of users, this bestseller closely follows the popular introductory Perl course taught by the authors since 1991. This 6th edition covers recent changes to the language up to version 5.14.Perl is suitable for almost any task on almost any platform, from short fixes to complete web applications. Learning Perl teaches you the basics and shows you how to write programs up to 128 lines long—roughly the size of 90% of the Perl programs in use today. Each chapter includes exercises to help you practice what you've just learned. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.Topics include:Perl data and variable typesSubroutinesFile operationsRegular expressionsString manipulation (including Unicode)Lists and sortingProcess managementSmart matchingUse of third party modules Printing History November 1993 First Edition.

Regular expressions are an extremely powerful tool for manipulating text and data. They are now standard features in a wide range of languages and popular tools, including Perl, Python, Ruby, Java, VB.NET and C# (and any language using the .NET Framework), PHP, and MySQL. If you don't use regular expressions yet, you will discover in this book a whole new world of mastery over your data. If you already use them, you'll appreciate this book's unprecedented detail and breadth of coverage. If you think you know all you need to know about regular expressions, this book is a stunning eye-opener. As this book shows, a command of regular expressions is an invaluable skill. Regular expressions allow you to code complex and subtle text processing that you never imagined could be automated. Regular expressions can save you time and aggravation. They can be used to craft elegant solutions to a wide range of problems. Once you've mastered regular expressions, they'll become an invaluable part of your toolkit. You will wonder how you ever got by without them. Yet despite their wide availability, flexibility, and unparalleled power, regular expressions are frequently underutilized. Yet what is power in the hands of an expert can be fraught with peril for the unwary. Mastering Regular Expressions will help you navigate the minefield to becoming an expert and help you optimize your use of regular expressions. Mastering Regular Expressions, Third Edition, now includes a full chapter devoted to PHP and its powerful and expressive suite of regular expression functions, in addition to enhanced PHP coverage in the central "core" chapters. Furthermore, this edition has been updated throughout to reflect advances in other languages, including expanded in-depth coverage of Sun's java.util.regex package, which has emerged as the standard Java regex implementation.Topics include: A comparison of features among different versions of many languages and tools, How the regular expression engine works, Optimization (major savings available here!), Matching just what you want, but not what you don't want, Sections and chapters on individual languages. Written in the lucid, entertaining tone that makes a complex, dry topic become crystal-clear to programmers, and sprinkled with solutions to complex real-world problems, Mastering Regular Expressions, Third Edition offers a wealth information that you can put to immediate use. - Publisher.

Any program worth its salt uses operating system services. Even the simplest program is likely to read input and produce output, and most real-world applications have more complex needs. They need to check the data and time, use the network, or start and communicate with other processes. "Systems programming" really means nothing more than writing software that uses these operating system services. UNIX Systems Programming for SVR4 gives you the nitty gritty details on how UNIX interacts with applications. Whether you're a student, system administrator, or software developer, if you're working on any System V Release 4 platform, you'll find this book indispensable. The book contains many extended examples on topics ranging from string manipulation to network programming. These examples can serve as starting points for your own applications. In addition to AT&T's release of SVR4, this book pays special attention to the three most important commercial UNIX implementations: Sun Microsystems' Solaris, Hewlett Packard's HP-UX 10, and Silicon Graphics' IRIX 5.3. It also includes notes on porting software from BSD UNIX to SVR4.

curses is a UNIX library of functions for controlling a terminal's display screen from a C program. It can be used to provide a screen driver for a program (such as a visual editor) or to improve a program's user interface. This handbook will help you make use of the curses library in your C programs. We have presented ample material on curses and its implementation in UNIX so that you understand the whole, as well as its parts. Note: This handbook covers Ken Arnold's original Berkeley implementation of curses, not the System V version. Topics covered include: - Windows, screens, and images. - Multiple windows. - The WINDOW structure.

"Attacks on government web sites, break-ins at Internet service providers, electronic credit card fraud, invasion of personal privacy by merchants as well as hackers - is this what the World Wide Web is really all about?".
