Proven strategies for maintaining and optimizing legacy code to get the most out of your existing applications. Examples in C-sharp, C++, and Java, as well as strategies for better using the industry standard modeling language: UML 2.0 Addresses the very concrete problems that programmers face working in the context of large untested code bases Based on successful classes for Object Mentor, the author helps organizations maintain older systems rather than go to the cost of developing new ones This book provides programmers with the ability to cost effectively handle common legacy code problems without having to go through the hugely expensive task of rewriting all existing code. It describes a series of practical strategies that developers can employ to bring their existing software applications under control. The author provides useful guidance about how to use these strategies when refactoring or making functional changes to code bases. One of the book´s key points is that it teaches developers to write tests that can be used to make sure they are not unintentionally changing the application as they optimize it. Examples are provided in Java, C++, and Csharp, and the book assumes that the reader has some knowledge of UML notation. Strategies using UML and code in C++ and Java primarily while language independent advice will be delivered in side bars and appendices for language specific users.

Backcover Get more out of your legacy systems: more performance, functionality, reliability, and manageability Is your code easy to change? Can you get nearly instantaneous feedback when you do change it? Do you understand it? If the answer to any of these questions is no, you have legacy code, and it is draining time and money away from your development efforts. In this book, Michael Feathers offers start-to-finish strategies for working more effectively with large, untested legacy code bases. This book draws on material Michael created for his renowned Object Mentor seminars: techniques Michael has used in mentoring to help hundreds of developers, technical managers, and testers bring their legacy systems under control. The topics covered include Understanding the mechanics of software change: adding features, fixing bugs, improving design, optimizing performance Getting legacy code into a test harness Writing tests that protect you against introducing new problems Techniques that can be used with any language or platform-with examples in Java, C++, C, and C# Accurately identifying where code changes need to be made Coping with legacy systems that aren´t object-oriented Handling applications that don´t seem to have any structure This book also includes a catalog of twenty-four dependency-breaking techniques that help you work with program elements in isolation and make safer changes. © Copyright Pearson Education.

The continuing growth in Internet services and the associated bandwidth consumption presents many challenges to be met at the network tiers. The deployment of a fiber-optic local network is important because as soon as it is in place, it provides broadband access to the Internet cloud. In this book, such architecture is envisioned to be moderate in costs and complexity through sharing of resources, simplified nodes at the user-side, and centralized network management. The provisioning of wireless networks and, consequently, the handling of mobile networking dynamics is considered to be essential to enable truly ubiquitous networking possibilities so the convergence of the optical and the radio domains has a central position in the book. The optical code division multiple access (OCDMA) technology serves as basis on top of which many networking concepts are evaluated. A unique insight is given in the complete trajectory of OCDMA system design from modeling, to photonic integration, until full-scale transmission experiments. This book is intended for (under-) graduate students and system designers in the area of fiber-optic local networks.
