Do you want to create .NET applications that provide high performance and scalability? Do you want to employ object–oriented programming techniques in a distributed environment? Do you want to maximize the reuse and maintainability of your code? Then this book is for you. In Rockford Lhotka's Expert C# 2008 Business Objects, you'll learn how to use advanced .NET Framework capabilities alongside object-oriented design and programming to create scalable, maintainable object–oriented applications. Better still, this book includes Component-based Scalable Logical Architecture (CSLA) .NET 3.6, a widely-used framework on which you can base your application development. By using the concepts and framework in the book, you can focus more on your business issues and less on technology. Using VS 2008 and C# 3.0, Rockford Lhotka shows you how CSLA .NET 3.6 allows great flexibility in object persistence, so business objects can use virtually any data sources available. The CSLA framework supports 1–, 2– and n–tier models through the concept of mobile objects. This provides the flexibility to optimize performance, scalability, security, and fault tolerance with no changes to code in the UI or business objects. Business objects based on CSLA.NET 3.6 automatically gain many advanced features that simplify the creation of Windows forms, web forms, WPF, WCF, WF, and web services interfaces, and LINQ.

The computing world today is in the middle of a revolution: mobile clients and cloud computing have emerged as the dominant paradigms driving programming and hardware innovation today. The Fifth Edition of Computer Architecture focuses on this dramatic shift, exploring the ways in which software and technology in the cloud are accessed by cell phones, tablets, laptops, and other mobile computing devices. Each chapter includes two real-world examples, one mobile and one datacenter, to illustrate this revolutionary change. Updated to cover the mobile computing revolution Emphasizes the two most important topics in architecture today: memory hierarchy and parallelism in all its forms. Develops common themes throughout each chapter: power, performance, cost, dependability, protection, programming models, and emerging trends ("What's Next") Includes three review appendices in the printed text. Additional reference appendices are available online. Includes updated Case Studies and completely new exercises.
Each chapter starts by showing the user experience we are going to create in the chapter. It then has a section discussing the major design decisions we face in building these features, and finally presents the 'solution' including the overall architecture and highlighting the most important code elements. The book presents a lot of real-world code, with comprehensive explanation and discussion. The full social network application is available for download from the Packt website, for you to examine, study, and modify. This book is written for ASP.NET and C# developers who want to build an enterprise-grade Social Network, either for their own business purposes or as a contract job for another company. The book assumes you have prior experience of developing web applications using ASP.NET 3.5, C# 3.0, SQL Server 2005/2008, and Visual Studio .NET 2008; it focuses on topics that will be of interest to existing developers not on providing step-by-step examples for each detail.

This book trains the student with the concepts needed to lay a solid foundation for joining this exciting field. More importantly, this book provides a framework for thinking about computer organization and design that will enable the reader to continue the lifetime of learning necessary for staying at the forefront of this competitive discipline. --John Crawford Intel Fellow Director of Microprocessor Architecture, Intel The performance of software systems is dramatically affected by how well software designers understand the basic hardware technologies at work in a system. Similarly, hardware designers must understand the far reaching effects their design decisions have on software applications. For readers in either category, this classic introduction to the field provides a deep look into the computer. It demonstrates the relationship between the software and hardware and focuses on the foundational concepts that are the basis for current computer design. Using a distinctive learning by evolution approach the authors present each idea from its first principles, guiding readers through a series of worked examples that incrementally add more complex instructions until they ha

Authors Jim Jeffers and James Reinders spent two years helping educate customers about the prototype and pre-production hardware before Intel introduced the first Intel Xeon Phi coprocessor. They have distilled their own experiences coupled with insights from many expert customers, Intel Field Engineers, Application Engineers and Technical Consulting Engineers, to create this authoritative first book on the essentials of programming for this new architecture and these new products. This book is useful even before you ever touch a system with an Intel Xeon Phi coprocessor. To ensure that your applications run at maximum efficiency, the authors emphasize key techniques for programming any modern parallel computing system whether based on Intel Xeon processors, Intel Xeon Phi coprocessors, or other high performance microprocessors. Applying these techniques will generally increase your program performance on any system, and better prepare you for Intel Xeon Phi coprocessors and the Intel MIC architecture. A practical guide to the essentials of the Intel Xeon Phi coprocessor Presents best practices for portable, high-performance computing and a familiar and proven threaded, scalar-vector programming model Includes simple but informative code examples that explain the unique aspects of this new highly parallel and high performance computational product Covers wide vectors, many cores, many threads and high bandwidth cache/memory architecture

Pro PHP Application Performance will help you understand all the technologies and components which play a role in how well your applications run. When seconds can mean the difference between retaining a user and losing a user, it's important for all of us to have optimization as part of our project roadmap. But what components within your application should you analyze? How should you optimize? And how can you measure how well your application is performing? These are some of the questions that are answered in this book. Along the way you will also learn the "why" of optimizing. You’ll discover why you should optimize a specific component, why selecting one function over another is beneficial, and how to find and use the optimization tools available to the open source community. You’ll also learn how to deploy caching software as well as web server software. Pro PHP Application Performance will also teach you more advanced techniques, such as: Using Xdebug to profile functions that are not running as efficiently as possible. Comparing opcode executed by different PHP functions to narrow the search for functions that run efficiently. Using strace to analyze Apache while your application is served to the user. Once you complete this book you will have a complete sense of where to start optimizing and, most importantly, have the tools which allow you to continue optimizing in other PHP applications going forward. What you’ll learn How to improve the performance of existing PHP applications How to maximize the performance of existing operating systems and databases How to refactor existing PHP code for better performance How to identify and rectify bottlenecks in PHP code How to take advantage of variable caching to increase performance Strategies for selecting server hardware for best performance Who this book is for This book will appeal to established PHP developers who wish to write new, complex applications or want to rearchitect existing ones.

Efficient management of resources is critical in the execution of any kind of software. From embedded software in a mobile device to software in a large enterprise server, it is important that resources, such as memory, threading, files, or network connections, are managed efficiently to allow the systems to function properly and effectively. As the need for resource management is often discovered late in the software development lifecycle, and changing the system design at this late stage is difficult, it is important that such tasks are performed early in the lifecycle. Since systems belonging to different domains have different system constraints and requirements, a technique that works well in a particular system or configuration might not be so effective in another. POSA 3 uses patterns to present techniques for implementing effective resource management in a system. The patterns are covered in detail, making use of several examples, and, as in previous POSA volumes, directions are given on how to implement the presented patterns. Additionally, the volume presents a thorough introduction into resource management, and two case studies where the patterns are applied to the domains of ad hoc networking and mobile radio networks. The patterns are grouped by different areas of resource management and hence address the complete lifecycle of resources: resource acquisition, coordination and release.
