This book is meant to be a springboard from which you can start pursuing more detailed knowledge in the areas that interest you. Following are some ideas about areas that you may wish to continue exploring, depending on your career goals:

WHO SHOULD READ THIS BOOK A part of the title of this book reads “A Beginner’s Guide”; this is mostly apt. But what the title should say is “A Beginner’s to Linux Administration Guide,” because we do make a few assumptions about you, the reader. (And we jolly well couldn’t use that title because it was such a mouthful and not sexy enough.) But seriously, we assume that you are already familiar with Microsoft Windows servers at a “power user” level or better. We assume that you are familiar with the terms (and some concepts) necessary to run a small- to medium-sized Windows network. Any experience with bigger networks or advanced Windows technologies, such as Active Directory, will allow you to get more from the book but is not required. We make this assumption because we did not want to write a guide for dummies. There are already enough books on the market that tell you what to click without telling you why; this book is not meant to be among those ranks. Furthermore, we did not want to waste time writing about information that we believe is common knowledge for power users of Windows. Other people have already done an excellent job of conveying that information, and there is no reason to repeat that work here. In addition to your Windows background, we assume that you’re interested in having more information about the topics here than the material we have written alone. After all, we’ve only spent 30 to 35 pages on topics that have entire books devoted to them! For this reason, we have scattered references to other books throughout the chapters. We urge you to take advantage of these recommendations. No matter how advanced you are, there is always something new to learn. We feel that seasoned Linux system administrators can also benefit from this book because it can serve as a quick how-to cookbook on various topics that may not be the seasoned reader’s strong points. We understand that system administrators generally have aspects of system administration that they like or loath. For example, backups is not one of the author’s favorite aspects of system administration, and this is reflected in the half a page we’ve dedicated to backups—just kidding, we’ve actually dedicated an entire chapter to backups.

Many businesses want to run their e-mail servers on Linux for greater control and flexibility of corporate communications, but getting started can be complicated. The attractiveness of a free-to-use and robust e-mail service running on Linux can be undermined by the apparent technical challenges involved. Some of the complexity arises from the fact that an e-mail server consists of several components that must be installed and configured separately, then integrated together. This book gives you just what you need to know to set up and maintain an e-mail server. Unlike other approaches that deal with one component at a time, this book delivers a step-by-step approach across all the server components, leaving you with a complete working e-mail server for your small business network.

Apache ActiveMQ is a message broker for remote communication between systems using the Java Message Service specfification. Although ActiveMQ is written in Java, APIs for many languages than other Java are provided including C/C++, .NET, Perl, PHP, Python, Ruby and many more. This book provides the information needed to understand, configure and use ActiveMQ successfully to meet the requirements of many business applications.

Build engineers and project managers might refer to Maven as something more comprehensive: a project management tool. What is the difference? A build tool such as Ant is solely focused on preprocessing, compilation, packaging, testing, and distribution. A project management tool such as Maven provides a superset of features found in a build tool. In addition to providing build capabilities, Maven can also run reports, generate a web site, and facilitate communication among members of a working team. A more formal definition of Apache Maven: Maven is a project management tool which encompasses a project object model, a set of standards, a project lifecycle, a dependency management system, and logic for executing plugin goals at defined phases in a lifecycle. When you use Maven, you describe your project using a well-defined project object model, Maven can then apply cross-cutting logic from a set of shared (or custom) plugins.

Welcome to the Fedora 12 User Guide! This guide is intended for users who have a working Fedora 12 system and are able to use a mouse and keyboard.

Because of the increased reliance on powerful, networked computers to help run businesses and keep track of our personal information, entire industries have been formed around the practice of network and computer security. Enterprises have solicited the knowledge and skills of security experts to properly audit systems and tailor solutions to fit the operating requirements of the organization. Because most organizations are increasingly dynamic in nature, with workers accessing company IT resources locally and remotely, the need for secure computing environments has become more pronounced.

This book has two goals, and which of these applies to you depends on your background. For experienced DBAs, the goal is to introduce you to the new features of SQL Server 2008 that will improve your administration routines. For new DBAs, or for those who administer databases on a part-time basis, the goal is to fast-track your adherence to best practices by avoiding common mistakes. In either case, the intention is not to give you step-by-step instructions on how to do a particular task but to provide general directions on best practices. You’ll need to do the hard yards yourself, but my hope is that this book will steer you in the right direction and save you a lot of time and energy by avoiding the mistakes that I’ve made myself—sometimes more than once!

With the great advances in digital data compression (coding) technologies and the rapid growth in the use of IP-based Internet, along with the quick deployment of last-mile wireline and wireless broadband access, networked multimedia applications have created a tremendous impact on computing and network infrastructures. The four most critical and indispensable components involved in a multimedia networking system are: (1) data compression (source encoding) of multimedia data sources, e.g., speech, audio, image, and video; (2) quality of service (QoS) streaming architecture design issues for multimedia delivery over best-effort IP networks; (3) effective dissemination multimedia over heterogeneous IP wireless broadband networks, where the QoS is further degraded owing to the dynamic changes in end-to-end available bandwidth caused by wireless fading or shadowing and link adaptation; (4) effective digital rights management and adaptation schemes, which are needed to ensure proper intellectual property management and protection of networked multimedia content. This book has been written to provide an in-depth understanding of these four major considerations and their critical roles in multimedia networking. More specifically, it is the first book to provide a complete system design perspective based on existing international standards and state-of-the-art networking and infrastructure technologies, from theoretical analyses to practical design considerations. The book also provides readers with learning experiences in multimedia networking by offering many development-software samples for multimedia data capturing, compression, and streaming for PC devices, as well as GUI designs for multimedia applications. The coverage of the material in this book makes it appropriate as a textbook for a one-semester or two-quarter graduate course. Moreover, owing to its balance of theoretical knowledge building and practical design integration, it can serve also as a reference guide for researchers working in this subject or as a handbook for practising engineers.

Python for Software Design is a concise introduction to software design using the Python programming language. Intended for people with no programming experience, this book starts with the most basic concepts and gradually adds new material. Some of the ideas students find most challenging, like recursion and object-oriented programming, are divided into a sequence of smaller steps and introduced over the course of several chapters. The focus is on the programming process, with special emphasis on debugging. The book includes a wide range of exercises, from short examples to substantial projects, so that students have ample opportunity to practice each new concept.

This book will teach you how FileMaker Pro stores your information, and how you can rearrange that information to get the answers to meaningful questions, like which employees are due for performance reviews, who’s coming to the company picnic, and which amusement park has the best deal on Laser Tag so you can throw a party for your top 50 performers. You won’t have to learn to think like a programmer (or know the arcane terms they use), but you will learn how to bend FileMaker Pro’s hidden power to your will, and make it tell you everything it knows about your company, your stock portfolio, or how much you’ve spent on the replacement parts for the ’58 Bonneville Sport Coupe you’re rebuilding.

The FileMaker Pro 10 Bible features FileMaker Pro 10 and FileMaker Pro 10 Advanced. As a user wishing to create basic solutions, FileMaker Pro 10 is an ideal place for you to start, and the bulk of the information in this book will be immediately useful to you. For more complex requirements or for serious development work, you’ll find that FileMaker Pro 10 Advanced offers numerous advantages, with improved diagnostics and powerful developer-oriented features — and again, you’ll find information herein to ensure that you’re able to get the most out of your purchase. In addition, FileMaker, Inc. provides the server-based (Web and local network) deployment products FileMaker Server 10 and FileMaker Server 10 Advanced, providing you with options to host FileMaker solutions for large workgroups. While the Server products aren’t the focus of the FileMaker Pro 10 Bible, I nevertheless include some references to design considerations for multiuser deployment.

Testing applications for mobile phones is difficult, time-consuming and hard to do effectively. Many people have limited their testing efforts to hands-on testing of an application on a few physical handsets, and they have to repeat the process every time a new version of the software is ready to test. They may miss many of the permutations of real-world use, and as a consequence their users are left with the unpleasant mess of a failing application on their phone. Test automation can help to increase the range and scope of testing, while reducing the overhead of manual testing of each version of the software. However automation is not a panacea, particularly for mobile applications, so we need to pick our test automation challenges wisely. This book is intended to help software and test engineers pick appropriately to achieve more; and as a consequence deliver better quality, working software to users. This Synthesis lecture provides practical advice based on direct experience of using software test automation to help improve the testing of a wide range of mobile phone applications, including the latest AJAX applications. The focus is on applications that rely on a wireless network connection to a remote server, however the principles may apply to other related fields and applications. We start by explaining terms and some of the key challenges involved in testing smartphone applications. Subsequent chapters describe a type of application e.g. markup, AJAX, Client, followed by a related chapter on how to test each of these applications. Common test automation techniques are covered in a separate chapter, and finally there is a brief chapter on when to test manually. The book also contains numerous pointers and links to further material to help you to improve your testing using automation appropriately.

With the Fedora Linux operating system and the instructions in this book, you can transform your PC into a safe, powerful, and free computer system. Starting with Fedora, you can simply replace (or coexist with) Microsoft Windows on your everyday desktop computer. You can also configure your computer to share your files, printers, Web pages, or directory services to other computers. Then, if you choose, you can transition your skills to manage anything from a small office to a large, corporate Red Hat Enterprise Linux computer installation. This book tells you how and gives you all the software you need to do it.

This book is a collection of recipes for the working Linux sysadmin–a set of stand-alone quick guides and tips that you can keep on your desk for easy reference. Hardcore in-depth manuals are great when you have the time to sit down and read through them thoroughly, but that’s not always the case when you have a bug that you needed fixed yesterday. This book is aimed at giving you tools to fix problems faster but also to help you set up software and systems to avoid problems showing up in the first place. Or at least to help you catch them sooner and solve them faster when they do show up. I wrote this because when working as a sysadmin, I spent a lot of time hunting for just this sort of information. This is a collection of things that I’ve personally found useful and wanted to share with other people in my position.

Windows Server 2008 R2, or simply R2 for short, is the second release of Windows Server 2008. It isn’t a completely new release, but rather adds additional features and refinements to the existing release. In this book, we focus on the new features and refinements in R2. We assume you have at least a general knowledge of Windows Server, and that you have some familiarity with Windows Server 2008, although we don’t assume you’re actively running Windows Server 2008. Where an R2 feature is a refinement of a feature that was new in Windows Server 2008, we provide background on the Windows Server 2008 feature to provide context.

Welcome to XSLT and XPath, two members of the W3C XML family of standards. This book concentrates on using XSLT and XPath to solve problems that you are likely to encounter every day in writing XSLT stylesheets. I have tried to focus most attention on the features that you will need frequently, while still treating other aspects of the subject in brief. You can find additional detailed information in the Quick Reference appendixes, and in more advanced works such as Michael Kay’s XSLT 2.0 and XPath 2.0 Programmers Reference, also in the Wrox list.

Mobile is a rapidly growing space that is yet to reach its full potential and reach worldwide. The combination of mobility, form factor, price, social media, and a global market is enabling scenarios that previously were either hard to imagine or to develop. Developers, both professional and otherwise, are fl ocking to mobile platforms to create applications and games. An approachable, effective, integrated application platform is a goal that every software vendor should be aiming for. The Windows Phone 7 application platform enables developers to create engaging consumer experiences running on a Windows Phone. It is built upon existing Microsoft tools and technologies such as Visual Studio, Expression Blend, Silverlight, and the XNA framework. Developers already familiar with those technologies will be able to create new applications for the Windows Phone quickly and easily. This book helps you to understand the Windows Phone application framework. It focuses on Windows Phone design guidelines, provides guidance architecture, and solidifies it with hands-on, real-world development scenarios. It is comprehensive, highly readable, and replete with useful real-world examples. I highly recommend this book for smartphone developers, IT professionals, and engineering managers. Whether you are new, or one who has experience on the iOS and Android platforms, this book serves as the ideal reference for development on the Windows Phone.

Java Programming, Fifth Edition provides the beginning programmer with a guide to developing applications using the Java programming language. Java is popular among professional programmers because it can be used to build visually interesting graphical user interface (GUI) and Web-based applications. Java also provides an excellent environment for the beginning programmer—a student quickly can build useful programs while learning the basics of structured and object-oriented programming techniques. This textbook assumes that you have little or no rogramming experience. This book provides a solid background in good object-oriented programming techniques and introduces object-oriented terminology using clear, familiar language. The writing is nontechnical and emphasizes good programming practices. The examples are business examples; they do not assume a mathematical background beyond high-school business math. In addition, the examples illustrate only one or two major points; they do not contain so many features that you become lost following irrelevant and extraneous details. The explanations in this textbook are written clearly in straightforward sentences so that native and non-native English speakers alike can master the programming concepts. Complete, working code examples appear frequently in each chapter; these examples help the student make the transition from the theoretical to the practical. The code presented in each chapter is also provided on disk, so that students can easily run the programs and experiment with changes to them.

This book covers every aspect of mobile app development, starting with major application components and screen layout and design, before moving on to how to manage sensors such as internal gyroscopes and near field communications. Towards the end, it delves into smartphone multimedia capabilities as well as graphics and animation, web access, and GPS. Whether you are writing your first app or your hundredth, this is a book that you will come back to time and time again, with its many tips and tricks on the rich features of Android 3.

The concept of wavelet analysis has been in place in one form or the other since the beginning of this century. The Littlewood - Paley technique and Calder ó n - Zygmund theory in harmonic analysis and digital filter bank theoryin signal processing can be considered forerunners to wavelet analysis. However, in its present form, wavelet theory drew attention in the 1980s with the work of several researchers from various disciplines — Str ? mberg, Morlet, Grossmann, Meyer, Battle, Lemari é , Coifman, Daubechies, Mallat, and Chui, to name a few. Many other researchers have also made signifi cant contributions.

This book is a collection consists of 17 chapters each of which originally formed an individual article on DMXzone. Linda started out by writing a 12 article series but on finishing that, we realised the insight Linda brought to web design and developed the heme. In this book Linda firstly introduces the concepts of the elements and principles of design, and then looks at each of these aspects in detail, using real websites to provide good (and occasionally bad) examples of the points she's making. By constantly referring to actual websites Linda manages to show how theoretical considerations make practical sense. In chapters 12 and 13 Linda brings together the points and uses our new understanding to appreciate the care and skill that has gone into some websites. By walking us through a detailed deconstruction of several top websites our analytical skills are improved and the earlier teaching points are reinforced. The collection is rounded out by several chapters that dig deeper into the subject of typography and lastly a chapter on appreciating different approaches to navigation. Throughout Linda has provided numerous references and suggestions for further reading.

First of all, let’s get out of the way what this book is not… This book is about breadth rather than epth, so it may not cover some areas in as much detail as you would want. Secondly, this book is written for the professional edition of Visual Studio 2010, so we will not be covering some of the great new features available in Premium and Ultimate editions of Visual Studio. It’s not that these features are not important—it’s more that I believe the majority of developers utilize the professional edition and there’s more than enough to cover already.

With the latest release of the Xcode Developer Tools, the new developer has access to a formidable tool-chest for Mac and iPhone development that is easier to use than any previous version. The missing piece, to me, has always been a simple and clear description of the tools and technologies needed to write for the Mac and iPhone. That is why I have written this book.

The Cambridge Dictionary of Statistics aims to provide students of statistics, working statisticians and researchers in many disciplines who are users of statistics with relatively concise definitions of statistical terms. All areas of statistics are covered, theoretical, applied, medical, etc., although, as in any dictionary, the choice of which terms to include and which to exclude is likely to reflect some aspects of the compiler's main areas of interest, and I have no illusions that this dictionary is any different. My hope is that the dictionary will provide a useful source of reference for both specialists and non-specialists alike. Many definitions necessarily contain some mathematical formulae and/or nomenclature, others contain none. But the difference in mathematical content and level among the definitions will, with luck, largely reflect the type of reader likely to turn to a particular definition. The non-specialist looking up, for example, Student’s t-tests will hopefully find the simple formulae and associated written material more than adequate to satisfy their curiosity, while the specialist seeking a quick reminder about spline functions will find the more extensive technical material just what they need.

VHDL is defined by IEEE Standard 1076, IEEE Standard VHDL Language Reference Manual (the VHDL LRM). The original standard was approved in 1987. IEEE procedures require that standards be periodically reviewed and either reaffirmed or revised. The VHDL standard was revised in 1993, 2000, and 2002. In each revision, new language features were added and some existing features enhanced. The aim in each revision was to improve the language as a tool for design and verification of digital systems.
