Algebraic Codes for Data Transmission
The need to transmit and store massive amounts of data reliably and without error is a vital part of modern communications systems. Error-correcting codes play a fundamental role in minimising data corruption caused by defects such as noise, interference, crosstalk and packet loss. This book provides an accessible introduction to the basic elements of algebraic codes, and discusses their use in a variety of applications. The author describes a range of important coding techniques, including Reed-Solomon codes, BCH codes, trellis codes, and turbocodes. Throughout the book, mathematical theory is illustrated by reference to many practical examples. The book was first published in 2003 and is aimed at graduate students of electrical and computer engineering, and at practising engineers whose work involves communications or signal processing.

Code Over Country
A hard-hitting exposé of SEAL Team 6, the US military's best-known brand, that reveals how the Navy SEALs were formed, then sacrificed, in service of American empire.The Navy SEALs are, in the eyes of many Americans, the ultimate heroes. When they killed Osama Bin Laden in 2011, it was celebrated as a massive victory. Former SEALs rake in cash as leadership consultants for corporations, and young military-bound men dream of serving in their ranks.But the SEALs have lost their bearings. Investigative journalist Matthew Cole tells the story of the most lauded unit, SEAL Team 6, revealing a troubling pattern of war crimes and the deep moral rot beneath authorized narratives. From their origins in World War II, the SEALs have trained to be specialized killers with short missions. As the wars in Iraq and Afghanistan became the endless War on Terror, their violence spiraled out of control.Code Over Country details the high-level decisions that unleashed the SEALs' carnage and the coverups that prevented their crimes from coming to light. It is a necessary and rigorous investigation of the unchecked power of the military-and the harms enacted by and upon soldiers in America's name.

Clean Code in Python
Getting the most out of Python to improve your codebaseKey FeaturesSave maintenance costs by learning to fix your legacy codebaseLearn the principles and techniques of refactoringApply microservices to your legacy systems by implementing practical techniquesBook DescriptionPython is currently used in many different areas such as software construction, systems administration, and data processing. In all of these areas, experienced professionals can find examples of inefficiency, problems, and other perils, as a result of bad code. After reading this book, readers will understand these problems, and more importantly, how to correct them. The book begins by describing the basic elements of writing clean code and how it plays an important role in Python programming. You will learn about writing efficient and readable code using the Python standard library and best practices for software design. You will learn to implement the SOLID principles in Python and use decorators to improve your code. The book delves more deeply into object oriented programming in Python and shows you how to use objects with descriptors and generators. It will also show you the design principles of software testing and how to resolve software problems by implementing design patterns in your code. In the final chapter we break down a monolithic application to a microservice one, starting from the code as the basis for a solid platform. By the end of the book, you will be proficient in applying industry approved coding practices to design clean, sustainable and readable Python code. What you will learnSet up tools to effectively work in a development environmentExplore how the magic methods of Python can help us write better codeExamine the traits of Python to create advanced object-oriented designUnderstand removal of duplicated code using decorators and descriptorsEffectively refactor code with the help of unit testsLearn to implement the SOLID principles in PythonWho this book is forThis book will appeal to team leads, software architects and senior software engineers who would like to work on their legacy systems to save cost and improve efficiency. A strong understanding of Programming is assumed.

Programming Entity Framework - Code First
This mini book will act as an extension to Programming Entity Framework 2nd Edition. Code First is an additional means of building a model to be used with the Entity Framework and is creating a lot of excitement in the .NET development community. The reader will begin with an overview of what Code First is, why it was created, how it fits into the Entity Framework and when to use it over the alternatives. Next the reader will gain an understanding of how Code First's built in conventions work and how to override them with configuration - whether they choose to use attribute based Data Annotations or strongly typed Fluent API configurations. The mini-book will then review the modeling possibilities of Code First, looking first at the impact of its conventions and then demonstrating how to override that behavior (and its impact on the database) first with the Annotations and then with the Fluent API. The book will also explore how Code First Database initialization works, the options it provides and how they impact your application development and database. Finally the reader will get a chance to see Code First in action in a small application.Because more complex application development with Code First will depend on an understanding of the DbContext API, which is the focus of Minibook #2, readers will see additional application scenarios with Code First in that following mini-book.

Codes and Consequences
This edited volume examines the implications of the phenomenon known as codeswitching, where, in given situations, different people with access to the same linguistic repertoire (or one person in different situations) will sometimes make very different linguistic choices. Employing Myers-Scotton's concept of "markedness" the contributors examine codeswitching in situations like everyday conversation, literary texts, sermons, and others to show the underlying socialsubtexts of the choices people make.

No Code Required
No Code Required presents the various design, system architectures, research methodologies, and evaluation strategies that are used by end users programming on the Web. It also presents the tools that will allow users to participate in the creation of their own Web. Comprised of seven parts, the book provides basic information about the field of end-user programming. Part 1 points out that the Firefox browser is one of the differentiating factors considered for end-user programming on the Web. Part 2 discusses the automation and customization of the Web. Part 3 covers the different approaches to proposing a specialized platform for creating a new Web browser. Part 4 discusses three systems that focus on the customized tools that will be used by the end users in exploring large amounts of data on the Web. Part 5 explains the role of natural language in the end-user programming systems. Part 6 provides an overview of the assumptions on the accessibility of the Web site owners of the Web content. Lastly, Part 7 offers the idea of the Web-active end user, an individual who is seeking new technologies.

Gender Codes
The computing profession faces a serious gender crisis. Today, fewer women enter computing than anytime in the past 25 years. This book provides an unprecedented look at the history of women and men in computing, detailing how the computing profession emerged and matured, and how the field became male coded. Women's experiences working in offices, education, libraries, programming, and government are examined for clues on how and where women succeeded—and where they struggled. It also provides a unique international dimension with studies examining the U.S., Great Britain, Germany, Norway, and Greece. Scholars in history, gender/women's studies, and science and technology studies, as well as department chairs and hiring directors will find this volume illuminating.
