In a Nutshell (O'Reilly) - Böcker

O'Reilly's bestselling book on Linux's bash shell is at it again. Now that Linux is an established player both as a server and on the desktop Learning the bash Shell has been updated and refreshed to account for all the latest changes. Indeed, this third edition serves as the most valuable guide yet to the bash shell. As any good programmer knows, the first thing users of the Linux operating system come face to face with is the shell the UNIX term for a user interface to the system. In other words, it's what lets you communicate with the computer via the keyboard and display. Mastering the bash shell might sound fairly simple but it isn't. In truth, there are many complexities that need careful explanation, which is just what Learning the bash Shell provides. If you are new to shell programming, the book provides an excellent introduction, covering everything from the most basic to the most advanced features. And if you've been writing shell scripts for years, it offers a great way to find out what the new shell offers. Learning the bash Shell is also full of practical examples of shell commands and programs that will make everyday use of Linux that much easier.With this book, programmers will learn: * How to install bash as your login shell * The basics of interactive shell use, including UNIX file and directory structures, standard I/O, and background jobs * Command line editing, history substitution, and key bindings * How to customize your shell environment without programming * The nuts and bolts of basic shell programming, flow control structures, command-line options and typed variables * Process handling, from job control to processes, coroutines and subshells * Debugging techniques, such as trace and verbose modes * Techniques for implementing system-wide shell customization and features related to system security

Ruby is an absolutely pure object-oriented scripting language written in C and designed with Perl and Python capabilities in mind. While its roots are in Japan, Ruby is slowly but surely gaining ground in the US. The goal of Yukihiro Matsumoto, creator of Ruby and author of this book, is to incorporate the strengths of languages like Perl, Python, Lisp and Smalltalk. Ruby is a genuine attempt to combine the best of everything in the scripting world. Since 1993, Ruby mailing lists have been established, Web pages have formed, and a community has grown around it. The language itself is very good at text processing and is notable for its broad object orientation. Ruby is portable and runs under GNU/Linux (and other Unices) as well as DOS, MS Windows and Mac. Written by Yukihiro Matsumoto ("Matz"), creator of the language, this text is a practical reference guide covering everything from Ruby syntax to the specifications of its standard class libraries. The book is based on Ruby 1.6, and is applicable to development versions 1.7 and the next planned stable version 1.8.

Introduced a quarter-century ago, the Oracle database remains the leading enterprise relational database management system (RDBMS) in the world. Oracle is a complex system, offering a myriad of products, languages, and tools. Frequent updates, releases, and editions complicate the ability of Oracle users to keep up with the huge amounts of frequently changing information about the database and its capabilities. The goal of "Oracle in a Nutshell" is to bring order to the chaos of Oracle information -- to pull together the most essential information on Oracle architecture, syntax, and user interfaces. The content and format of this book combine to boil down vital Oracle commands, language constructs, parameters, and file formats in a succinct and highly accessible desktop reference. The book covers the information that database administrators PL/SQL and Java developers, and system, network, and security administrators need as they manage Oracle databases and write code for these databases.It includes: Oracle Foundations - Overview of the Oracle architecture (memory structures and fundamental concepts), Oracle's various editions and packaging options, summary of the initialization file parameters and data dictionary views, and fundamentals of Oracle's concurrency scheme, security mechanisms (privileges, profiles, roles), and networking files (TNSNAMES.ORA, SQLNET.ORA, LISTENER.ORA, DAP.ORA, NAMES.ORA, CMAN.ORA) and options. Oracle Languages - Syntax summary for SQL language statements, SQL function calls PL/SQL language statements and characteristics, PL/SQL built-in package headers, and Java (JDBC and SQLJ) interfaces to the Oracle database. Oracle Tools - Commands provided with SQL*Plus, SQL*Loader, Import and Export, Oracle Recovery Manager (RMAN) and other backup/recovery methods, Oracle Enterprise Manager, and various performance tuning tools (Explain Plan, TKPROF, AUTOTRACE, UTLBSTAT, UTLESTAT, Statspack).

System developers have used modeling languages for decades to specify, visualize, construct, and document systems. The Unified Modeling Language (UML) is one of those languages. UML makes it possible for team members to collaborate by providing a common language that applies to a multitude of different systems. Essentially, it enables you to communicate solutions in a consistent, tool-supported language. Today, UML has become the standard method for modeling software systems, which means you're probably confronting this rich and expressive language more than ever before. And even though you may not write UML diagrams yourself, you'll still need to interpret diagrams written by others. UML 2.0 in a Nutshell from O'Reilly feels your pain. It's been crafted for professionals like you who must read, create, and understand system artifacts expressed using UML. Furthermore, it's been fully revised to cover version 2.0 of the language. This comprehensive new edition not only provides a quick-reference to all UML 2.0 diagram types, it also explains key concepts in a way that appeals to readers already familiar with UML or object-oriented programming concepts.Topics include: * The role and value of UML in projects * The object-oriented paradigm and its relation to the UML * An integrated approach to UML diagrams * Class and Object, Use Case, Sequence, Collaboration, Statechart, Activity, Component, and Deployment Diagrams * Extension Mechanisms * The Object Constraint Language (OCL) If you're new to UML, a tutorial with realistic examples has even been included to help you quickly familiarize yourself with the system.

When Microsoft releases Windows Vista, the new operating system will support applications that employ graphics now used by computer games-clear, stunning and active. The cornerstone for building these new user interfaces is XAML ("Zammel"), the XML-based markup language that works with Windows Presentation Foundation (WPF), Vista's new graphics subsystem. An acronym for Extensible Application Markup Language, XAML offers a wealth of new controls and elements with exciting capabilities, including animation and rendering of 3D graphics. Windows developers are already jazzed by the possibilities of using XAML for fixed and flow format documents like PDF and HTML, 2D and 3D vector-based graphics, form development, animation, audio and video, transparent layering, and a lot more. Many feel that XAML will eliminate the need for multiple file formats or plug-ins (read: Flash), while lowering development costs and reducing time to market. The problem is, most developers don't know XAML. While it is fairly easy to understand, you still need a quick guide to bring you up to speed before Vista's release, and that's where this book's simple, no nonsense approach comes in."XAML in a Nutshell" covers everything necessary to design user interfaces and .NET applications that take advantage of WPF. Prerequisites such as Microsoft's new unified build system, MSBuild, and core XAML constructs and syntax-including shortcuts - are all presented with plenty of examples to get you started. The Core XAML Reference section lets you dig even deeper into syntax rules and attributes for all XAML elements with a series of quick-reference chapters. This section divides XAML elements into logical categories of elements, controls, shapes and geometry, layout, animations, and transformations for easy reference. "XAML in a Nutshell" helps you learn, firsthand, how to use this XML-based markup language to implement the new generation of user interface graphics. As one reviewer noted, "Strong code examples and an efficient, conversational style take the tedium out of learning XAML and make the subject understandable-even interesting."

The online documentation of VB/VBA language components seems to follow the 80/20 rule: the basic facts that you need to use a language statement are provided in the documentation. But the additional 20 percent that you need to use it effectively or to apply it to special cases is conspicuously absent. To a professional VB/VBA programmer, though, this missing 20 percent of the language's documentation isn't a luxury, it's a necessity. And in VB & VBA in a Nutshell: The Language, it finally is available. The bulk of the book consists of an alphabetical reference to the statements, procedures, and functions of the VB/VBA language. Each entry has a standardized listing containing the following information: * Its syntax, using standard code conventions * Differences in the operation of the keyword in a macro environment (e.g., in Office) and in Visual Basic, if there are any * A list of arguments accepted by the function or procedure, if any * A description of the data type returned by a function * The finer points of a keyword's usage that are often omitted from or blurred over by the documentation * Tips and gotchas that include undocumented behaviors and practical applications for particular language elements -- a section particularly invaluable for diagnosing or avoiding potential programming problems * A brief, nonobvious example that illustrates the use of the keyword Also included in VB & VBA in a Nutshell: The Language is a brief overview of the VB/VBA language, including: * Basic VBA programming concepts, such as its data types and its support for variables, constants, and arrays * Error handling in VBA applications * Object programming with VBA * Using VBA with particular applications.Excel and Project are utilized to show how to work with an application's integrated development environment and to take advantage of its object model Regardless of how much experience you have programming with VBA, this is the book you'll pick up time and time again both as your standard reference guide and as a tool for troubleshooting and identifying programming problems. VB & VBA in a Nutshell: The Language is the definitive reference for Visual Basic and VBA developers.
