XSLT documents a core technology for processing XML. Originally created for page layout, XSLT (Extensible Stylesheet Transformations) is now much more: a general-purpose translation tool, a system for reorganizing document content, and a way to generate multiple results-- such as HTML, WAP, and SVG--from the same content.What sets XSLT apart from other books on this critical tool is the depth of detail and breadth of knowledge that Doug Tidwell, a developer with years of XSLT experience, brings to his concise treatment of the many talents of XSLT. He covers XSLT and XPath, a critical companion standard, and addresses topics ranging from basic transformations to complex sorting and linking. He explores extension functions on a variety of different XSLT processors and shows ways to combine multiple documents using XSLT. Code examples add a real-world dimension to each technique.Useful as XSLT is, its peculiar characteristics make it difficult to get started in, and the ability to use advanced techniques depends on a clear and exact understanding of how XSLT templates work and interact. For instance, the understanding of "variables" in XSLT is deeply different from the understanding of "variables" in procedural languages. The author explains XSLT by building from the basics to its more complex and powerful possibilities, so that whether you're just starting out in XSLT or looking for advanced techniques, you'll find the level of information you need.

Programming Python focuses on advanced uses of the Python programming/scripting language, which has evolved from an emerging language of interest primarily to pioneers, to a widely accepted tool that traditional programmers use for real day-to-day development tasks. With Python, you can do almost anything you can do with C++; but Python is an interpreted language designed for rapid application development and deployment. Among other things, Python supports object-oriented programming; a remarkably simple, readable, and maintainable syntax; integration with C components; and a vast collection of pre-coded interfaces and utilities.As Python has grown to embrace developers on a number of different platforms (Unix, Linux, Windows, Mac), companies have taken notice and are adopting Python for their products. It has shown up animating the latest Star Wars movie, serving up maps and directories on the Internet, guiding users through Linux installations, testing chips and boards, managing Internet discussion forums, scripting online games, and even scripting wireless products.Programming Python is the most comprehensive resource for advanced Python programmers available today. Reviewed and endorsed by Python creator Guido van Rossum, who also provides the foreword, this book zeroes in on real-world Python applications. It's been updated for Python 2.0 and covers Internet scripting, systems programming, Tkinter GUIs, C integration domains, and new Python tools and applications. Among them: IDLE, JYthon, Active Scripting and COM extensions, Zope, PSP server pages, restricted execution mode, the HTMLgen and SWIG code generators, thread support, CGI and Internet protocol modules. Such applications are the heart and soul of this second edition.Veteran O'Reilly author Mark Lutz has included a platform-neutral CD-ROM with book examples and various Python-related packages, including the full Python 2.0 source code distribution.

IPv6, the next generation Internet Protocol, has been in the works since the early 90s when the rapid growth of the Internet threatened to exhaust existing IP addresses. Drawing on 20 years--operational experience with the existing protocol (IPv4), the new protocol offers scalability, increased security features, real-time traffic support, and auto-configuration so that even a novice user can connect a machine to the Internet. But what does this mean for IT professionals? Having learned all the strengths and weaknesses of the old protocol, will you need to start from scratch with the new?IPv6 Essentials provides a succinct, in-depth tour of all the new features and functions in IPv6, guiding you through everything you?ll need to know to get started, including how to configure IPv6 on hosts and routers, and which applications currently support IPv6. Aimed at system and network administrators, engineers, network designers, and IT managers, this book will help you plan for, design, and integrate IPv6 into your current IPv4 infrastructure.Beginning with a short history of IPv6, author Silvia Hagen provides an overview of the new functionality and describes some live test and production networks that are using the new protocol. Hagen then shares exhaustive discussions of the new IPv6 header format and Extension Headers, IPv6 address format, and IPv6 message format. IPv6 Essentials also covers:
<ul>
<li>Security in IPv6: concepts, requirements, and solutions. Includes the IPSEC framework and security elements available for authentication and encryption</li>
<li>Quality of Service: covers the types of QoS in IPv6 and how they can be implemented</li>

Practically every day, we read about a new type of attack on computer systems and networks. Viruses, worms, denials of service, and password sniffers are attacking all types of systems -- from banks to major e-commerce sites to seemingly impregnable government and military computers --at an alarming rate.Despite their myriad manifestations and different targets, nearly all attacks have one fundamental cause: the code used to run far too many systems today is not secure. Flaws in its design, implementation, testing, and operations allow attackers all-too-easy access.Secure Coding, by Mark G. Graff and Ken vanWyk, looks at the problem of bad code in a new way. Packed with advice based on the authors' decades of experience in the computer security field, this concise and highly readable book explains why so much code today is filled with vulnerabilities, and tells readers what they must do to avoid writing code that can be exploited by attackers. Writing secure code isn't easy, and there are no quick fixes to bad code. To build code that repels attack, readers need to be vigilant through each stage of the entire code lifecycle:
<ul>
<li>Architecture: during this stage, applying security principles such as "least privilege" will help limit even the impact of successful attempts to subvert software.</li>
<li>Design: during this stage, designers must determine how programs will behave when confronted with fatally flawed input data. The book also offers advice about performing security retrofitting when you don't have the source code -- ways of protecting software from being exploited even if bugs can't be fixed.</li>
<li>Implementation: during this stage, programmers must sanitize all program input (the character streams representing a programs' entire interface with its environment -- not just the command lines and environment variables that are the focus of most securityanalysis).</li>
<li>Testing: during this stage, programs must be checked using both static code checkers and runtime testing methods -- for example, the fault injection systems now available to check for the presence of such flaws as buffer overflow.</li>
<li>Operations: during this stage, patch updates must be installed in a timely fashion. In early 2003, sites that had diligently applied Microsoft SQL Server updates were spared the impact of the Slammer worm that did serious damage to thousands of systems.</li>
</ul>Beyond the technical, Secure Coding sheds new light on the economic, psychological, and sheer practical reasons why security vulnerabilities are so ubiquitous today. It presents a new way of thinking about these vulnerabilities and ways that developers can compensate for the factors that have produced such unsecured software in the past. It issues a challenge to all those concerned about computer security to finally make a commitment to building code the right way.
