With the growing popularity of Linux and the advent of Darwin, Unix has metamorphosed into something new and exciting. No longer perceived as a difficult operating system, more and more users are discovering the advantages of Unix for the first time. But whether you are a newcomer or a Unix power user, you'll find yourself thumbing through the goldmine of information in the new edition of Unix Power Tools to add to your store of knowledge. Want to try something new? Check this book first, and you're sure to find a tip or trick that will prevent you from learning things the hard way.The latest edition of this best-selling favorite is loaded with advice about almost every aspect of Unix, covering all the new technologies that users need to know. In addition to vital information on Linux, Darwin, and BSD, Unix Power Tools 3rd Edition now offers more coverage of bash, zsh, and other new shells, along with discussions about modern utilities and applications. Several sections focus on security and Internet access. And there is a new chapter on access to Unix from Windows, addressing the heterogeneous nature of systems today. You'll also find expanded coverage of software installation and packaging, as well as basic information on Perl and Python.Unix Power Tools 3rd Edition is a browser's book...like a magazine that you don't read from start to finish, but leaf through repeatedly until you realize that you've read it all. Bursting with cross-references, interesting sidebars explore syntax or point out other directions for exploration, including relevant technical details that might not be immediately apparent. The book includes articles abstracted from other O'Reilly books, new information that highlights program tricks and gotchas, tips posted to the Net over the years, and other accumulated wisdom.Affectionately referred to by readers as "the" Unix book, UNIX Power Tools provides access to information every Unix user is going to need to know. It will help you think creatively about UNIX, and will help you get to the point where you can analyze your own problems. Your own solutions won't be far behind.
The Resource Description Framework (RDF) is a structure for describing and interchanging metadata on the Web--anything from library catalogs and worldwide directories to bioinformatics, Mozilla internal data structures, and knowledge bases for artificial intelligence projects. RDF provides a consistent framework and syntax for describing and querying data, making it possible to share website descriptions more easily. RDF's capabilities, however, have long been shrouded by its reputation for complexity and a difficult family of specifications. Practical RDF breaks through this reputation with immediate and solvable problems to help you understand, master, and implement RDF solutions.Practical RDF explains RDF from the ground up, providing real-world examples and descriptions of how the technology is being used in applications like Mozilla, FOAF, and Chandler, as well as infrastructure you can use to build your own applications. This book cuts to the heart of the W3C's often obscure specifications, giving you tools to apply RDF successfully in your own projects.The first part of the book focuses on the RDF specifications. After an introduction to RDF, the book covers the RDF specification documents themselves, including RDF Semantics and Concepts and Abstract Model specifications, RDF constructs, and the RDF Schema. The second section focuses on programming language support, and the tools and utilities that allow developers to review, edit, parse, store, and manipulate RDF/XML. Subsequent sections focus on RDF's data roots, programming and framework support, and practical implementation and use of RDF and RDF/XML.If you want to know how to apply RDF to information processing, Practical RDF is for you. Whether your interests lie in large-scale information aggregation and analysis or in smaller-scale projects like weblog syndication, this book will provide you with a solid foundation for working with RDF.
Ajax can bring many advantages to an existing web application without forcing you to redo the whole thing. This book explains how you can add Ajax to enhance, rather than replace, the way your application works. For instance, if you have a traditional web application based on submitting a form to update a table, you can enhance it by adding the capability to update the table with changes to the form fields, without actually having to submit the form. That's just one example.

Adding Ajax is for those of you more interested in extending existing applications than in creating Rich Internet Applications (RIA). You already know the "business-side" of applications-web forms, server-side driven pages, and static content-and now you want to make your web pages livelier, more fun, and much more interactive. This book:

Provides an overview of Ajax technologies, and the importance of developing a strategy for changing your site before you sit down to codeExplains the heart and soul of Ajax: how to work with the XMLHttpRequest objectIntroduces and demonstrates several important Ajax libraries, including Prototype, script.aculo.us, rico, MochikitExplores the interactive element that is Ajax, including how to work with events and event handlers that work across browsersIntroduces the concept of web page as space, and covers three popular approaches to managing web spaceExplains how to make data updates, including adding new data, deleting, and making updates, all from within a single pageDescribes the effects Ajax has on the Web-breaking the back button, losing browser history, dynamic effects that disappear when the page is refreshed, and moreCovers advanced CSS effects, including drag and drop "scroll bars", pagination, and the use of SVG and the Canvas objectExplores mashups-Ajax's ability to combine data from different web services in any number of ways, directly in our web pagesYou don't need to start over to use Ajax. You can simply add to what you already have. This book explains how.
Do you think that only professionals with expensive tools and years of experience can work with web graphics? This guide tosses that notion into the trash bin.

Painting the Web is the first comprehensive book on web graphics to come along in years, and author Shelley Powers demonstrates how readers of any level can take advantage of the graphics and animation capabilities built into today's powerful browsers. She covers GIFs, JPEGs, and PNGs, raster and vector graphics, CSS, Ajax effects, the canvas objects, SVG, geographical applications, and more -- everything that designers (and non-designers) use to literally paint the Web.

More importantly, Shelley's own love of web graphics shines through in every example. Not only can you master the many different techniques, you also can have fun doing it.

Topics in Painting the Web include:

GIF, JPEG, PNG, lossy versus lossless compression, color management, and optimizationPhoto workflow, from camera to web page, including a review of photo editors, workflow tools, and RAW photo utilitiesTricks for best displaying your photos onlineNon-photographic raster images (icons and logos), with step-by-step tutorials for creating popular "Web 2.0" effects like reflection, shiny buttons, inlays, and shadowsVector graphicsAn SVG tutorial, with examples of all the major componentsTips and tricks for using CSSInteractive effects with Ajax such as accordions and fadesThe canvas object implemented in most browsersGeographical applications such as Google Maps and Yahoo Maps, with programming and non-programming examplesVisual effects such as forms and data displays in table or graphicsWeb design for the non-designer

Graphics are not essential to the web experience, but they do make the difference between a site that's functional and one that's lively, compelling, and exciting. Whether you want to spruce up a website, use photos to annotate your stories, create hot graphics, or provide compelling displays for your data, this is the book for you.
