Now updated in line with the 2011 syllabus, this quick-reference revision guide has been designed to help students prepare for their foundation exam. It is also a key reference aid for managers, practitioners, vendors and consultants in the workplace and while travelling. This handbook provides an introduction to the ITIL service lifecycle model and an overview of the ITIL qualification structure. It contains a chapter on each of the components of the lifecycle: service strategy, service design, service transition, service operation and continual service improvement.
This book distils into a single coherent handbook all the essentials of process automation at a depth sufficient for most practical purposes. No other book covers the gap between the theory and practice of control systems so comprehensively.
A single dramatic software failure can cost a company millions of dollars - but can be avoided with simple changes to design and architecture. This new edition of the best-selling industry standard shows you how to create systems that run longer, with fewer failures, and recover better when bad things happen.
Fundamentally, computers just deal with numbers. They store letters and other characters by assigning a number for each one. There are hundreds of different encoding systems for mapping characters to numbers, but Unicode promises a single mapping. Unicode enables a single software product or website to be targeted across multiple platforms, languages and countries without re-engineering. It´s no wonder that industry giants like Apple, Hewlett-Packard, IBM andMicrosoft have all adopted Unicode. Containing everything you need to understand Unicode, this comprehensive reference from O´Reilly takes you on a detailed guide through the complex character world. For starters, it explains how to identify and classify characters - whether they´re common, uncommon, or exotic. It then shows you how to type them, utilize their properties, and process character data in a robust manner. The book is broken up into three distinct parts. The first few chapters provide you with a tutorial presentation of Unicode and character data. It gives you a firm grasp of the terminology you need to reference various components, including character sets, fonts and encodings, glyphs and character repertoires. The middle section offers more detailed information about using Unicode and other character codes. It explains the principles and methods of defining character codes, describes some of the widely used codes, and presents code conversion techniques. It also discusses properties of characters, collation and sorting, line breaking rules and Unicode encodings. The final four chapters cover more advanced material, such as programming to support Unicode. You simply can´t afford to be without the nuggets of valuable information detailed in Unicode Explained.

This revised edition incorporates much-demanded updates throughout the book, based on feedback and corrections reported from classrooms since 2008 Learn the fundamentals of programming multiple threads accessing shared memory Explore mainstream concurrent data structures and the key elements of their design, as well as synchronization techniques from simple locks to transactional memory systems Visit the companion site and download source code, example Java programs, and materials to support and enhance the learning experience
The core book in SEI´s influential architecture curriculum, this book introduces software architecture both for practicing software engineers and for students pursuing careers in software design or management. It combines the authority of SEI´s pioneering curriculum with the proven pedagogical effectiveness of a book that´s been used for many years in countless training and college courses. The authors provide a comprehensive overview of the field of software architecture in a single, easy-to-digest package. This book will help readers understand: Why software architecture is critical to development projects and the organization as a whole Which technical and organizational factors influence architecture, and are in turn influenced by it How architecture drives quality attributes such as performance and reliability How to master and choose among today´s best architectural tactics
Spectral methods, particularly in their multidomain version, have become firmly established as a mainstream tool for scientific and engineering computation. While retaining the tight integration between the theoretical and practical aspects of spectral methods that was the hallmark of their 1988 book, Canuto et al. now incorporate the many improvements in the algorithms and the theory of spectral methods that have been made since then. This second new treatment, Evolution to Complex Geometries and Applications to Fluid Dynamics, provides an extensive overview of the essential algorithmic and theoretical aspects of spectral methods for complex geometries, in addition to detailed discussions of spectral algorithms for fluid dynamics in simple and complex geometries. Modern strategies for constructing spectral approximations in complex domains, such as spectral elements, mortar elements, and discontinuous Galerkin methods, as well as patching collocation, are introduced, analyzed, and demonstrated by means of numerous numerical examples. Representative simulations from continuum mechanics are also shown. Efficient domain decomposition preconditioners (of both Schwarz and Schur type) that are amenable to parallel implementation are surveyed. The discussion of spectral algorithms for fluid dynamics in single domains focuses on proven algorithms for the boundary-layer equations, linear and nonlinear stability analyses, incompressible Navier-Stokes problems, and both inviscid and viscous compressible flows. An overview of the modern approach to computing incompressible flows in general geometries using high-order, spectral discretizations is also provided. The recent companion book Fundamentals in Single Domains discusses the fundamentals of the approximation of solutions to ordinary and partial differential equations on single domains by expansions in smooth, global basis functions. The essential concepts and formulas from this book are included in the current text for the reader s convenience.
Learn to build Rails-based web applications using all the latest features offered in Rails 5.2. Author Stefan Wintermeyer begins by teaching the basics of Ruby 2.5 before proceeding through all aspects of Rails, utilizing clean, succinct examples - rather than a single large application. This book covers topics including Active Storage, Credentials, Active Record, Scaffolding, REST, Routing, Bundler, Forms, Cookies, and Sessions, all of which are vital for modern Rails web applications. To complement these topics you´ll also learn about test-driven development, Action Cable, Active Job, Action Mailer, I18n, Asset Pipeline, and caching. Finally, you´ll see a how-to for a production web server with nginx. This complete set of skills will set you up for a future of efficient and elegant Rails coding. What You Will Learn Use the Ruby on Rails web development framework Install and manage the Rails framework Persist data for your web application with Active Record Work with forms Apply a test-driven development approach to your Rails-based web applications Discover many Rails secrets and tips Who This Book Is For Beginners with at least some prior programming experience. Ruby experience is helpful, but not required.
