The average book on Agile software development describes a fairyland of greenfield projects, with wall-to-wall tests that run after every few edits, and clean & simple source code.
The average software project, in our industry, was written under some aspect of code-and-fix, and without automated unit tests. And we can't just throw this code away; it represents a significant effort debugging and maintaining. It contains many latent requirements decisions. Just as Agile processes are incremental, Agile adoption must be incremental too. No more throwing away code just because it looked at us funny.
Mike begins his book with a very diplomatic definition of "Legacy". I'l skip ahead to the undiplomatic version: Legacy code is code without unit tests.
Before cleaning that code up, and before adding new features and removing bugs, such code must be de-legacified. It needs unit tests.
To add unit tests, you must change the code. To change the code, you need unit tests to show how safe your change was.
The core of the book is a cookbook of recipes to conduct various careful attacks. Each presents a particular problem, and a relatively safe way to migrate the code towards tests.
Code undergoing this migration will begin to experience the benefits of unit tests, and these benefits will incrementally make new tests easier to write. These efforts will make aspects of a legacy codebase easy to change.
It's an unfortunate commentary on the state of our programming industry how much we need this book.

Capturing a wealth of experience about the design of object-oriented software, four top-notch designers present a catalog of simple and succinct solutions to commonly occurring design problems. Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves. The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns as your guide, you will learn how these important patterns fit into the software development process, and how you can leverage them to solve your own design problems most efficiently. Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other design constraints, and the consequences and trade-offs of using the pattern within a larger design. All patterns are compiled from real systems and are based on real-world examples. Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk. 0201633612B07092001

Compilers: Principles, Techniques and Tools, known to professors, students, and developers worldwide as the "Dragon Book," is available in a new edition. Every chapter has been completely revised to reflect developments in software engineering, programming languages, and computer architecture that have occurred since 1986, when the last edition published. The authors, recognizing that few readers will ever go on to construct a compiler, retain their focus on the broader set of problems faced in software design and software development.

An interactive guide to the fundamentals of the Java programming language utilizes icons, cartoons, and numerous other visual aids to introduce the features and functions of Java and to teach the principles of designing and writing Java programs.
Written by an expert in the game industry, Christer Ericson's new book is a comprehensive guide to the components of efficient real-time collision detection systems. The book provides the tools and know-how needed to implement industrial-strength collision detection for the highly detailed dynamic environments of applications such as 3D games, virtual reality applications, and physical simulators. Of the many topics covered, a key focus is on spatial and object partitioning through a wide variety of grids, trees, and sorting methods. The author also presents a large collection of intersection and distance tests for both simple and complex geometric shapes. Sections on vector and matrix algebra provide the background for advanced topics such as Voronoi regions, Minkowski sums, and linear and quadratic programming. Of utmost importance to programmers but rarely discussed in this much detail in other books are the chapters covering numerical and geometric robustness, both essential topics for collision detection systems. Also unique are the chapters discussing how graphics hardware can assist in collision detection computations and on advanced optimization for modern computer architectures. All in all, this comprehensive book will become the industry standard for years to come.
In his long-awaited book, Martin Fowler has done for application domain patterns what the Gang of Four [Gamma et al.] have done for general purpose design patterns in their book, Design Patterns: Elements of Reusable Object-Oriented Software. This book is a must have for all analysts and designers doing object-oriented business modeling and business process re-engineering. —Donald G. Firesmith, Knowledge Systems Corporation Fowler shares with you his wealth of object modeling experience and his keen eye for identifying repeating problems and transforming them into reusable models. Analysis Patterns provides a catalogue of patterns that have emerged in a wide range of domains, including trading, measurement, accounting, and organizational relationships.

The definitive OpenGL Shading Language reference AND tutorial - now fully updated and revised for the latest version * *Includes extensive new coverage, including a thorough discussion of GLSL for OpenGL ES, the emerging standard for handheld media devices. *Clear, approachable, and relevant examples that help programmers quickly address the challenges they're most likely to encounter. * Authored by experts who have been intimately involved in the design and evolution of the OpenGL Shading Language. OpenGL Shading Language, 3/e is the definitive guide to creating graphics applications with the newest version of the OpenGL Shading Language. Using this book, graphics programmers will learn how to exploit the full performance and flexibility of modern GPU hardware to create stunningly realistic and creative effects. One part reference, one part tutorial, this will be their go-to source from the moment they begin learning the language until they've become seasoned experts. This book's content has become ever more important to a wider spectrum of graphics programmers. For years, programmers treated graphics hardware as 'state machines' whose behavior could only be modified by changing bits of state. This severely limited the effects they could realistically achieve. The OpenGL Shading Language puts control of graphics hardware squarely in the programmer's hands: key stages of the graphics pipeline are now completely programmable. With this new freedom, of course, the programmer also gains new responsibilities. It's a fundamental paradigm shift -- and this book will help programmers make the leap. This edition covers significant enhancements in the new version of OpenGL Shading Language, including the latest version of GLSL for OpenGL ES, the emerging standard for handheld media devices. As in previous editions, however, it relies throughout on clear, approachable code samples that address the specific tasks and skills graphics programmers are most likely to need
