Book Description
Seattle's Gang of Four changed the face of the city in the 1960s, '70s, and '80s by bringing four ethnic groups together in battle against city powerbrokers over development, poverty, fishing rights, and gentrification. The four leaders learned quickly that working together provided greater results than working apart. This is the story of a powerful political alliance and lifelong friendships forged through sit-ins, protest rallies, and other acts of civil disobedience. "We got very good at occupying buildings," remarked one of the Gang. Bob Santos and Gary Iwamoto recall how a Native American, Asian American, African American, and Mexican American came together to fight for their neighborhoods and their people. Bob Santos has spent most of his life in the International District of Seattle. He grew up in the N.P. Hotel with his widowed father, Sammy Santos, a professional prizefighter. He was hired in 1972 to lead the International District Improvement Association (Inter*Im). During his tenure at Inter*Im, Santos organized property owners, businesses, residents, and activists from the Asian American community to preserve the neighborhood and build new housing. Gary Iwamoto is a regular contributing writer for the International Examiner, an Asian Pacific Islander community newspaper. He has written several plays, notably Miss Minidoka 1943, which was produced by the Northwest Asian American Theater. He and Bob Santos also wrote Humbows, Not Hot Dogs in 2002.

Prior knowledge of Salesforce and Force.com platform is recommended. What You Will Learn Apply OOPs principal in Apex to design a robust and efficient solution to address various facets to a business problem Get to grips with the benefits and applicability of using different design patterns in Apex Solve problems while instantiating, structuring and giving dynamic behavior to Apex classes Understand the implementation of creational, structural, behavioral, concurrency and anti-patterns in your application Follow the Apex best practices to resolve governor limit issues Get clued up about the Inheritance, abstract classes, polymorphism in Apex to deal with the object mechanism Master various design patterns and determine the best out of them Explore the anti patterns that could not be applied to Apex and their appropriate solutions In Detail Apex is an on-demand programming language providing a complete set of features for building business applications – including data models and objects to manage data. Apex being a proprietor programming language from Salesforce to be worked with multi tenant environment is a lot different than traditional OOPs languages like Java and C#. It acts as a workflow engine for managing collaboration of the data between users, a user interface model to handle forms and other interactions, and a SOAP API for programmatic access and integration. Apex Design Patterns gives you an insight to several problematic situations that can arise while developing on Force.com platform and the usage of Design patterns to solve them. Packed with real life examples, it gives you a walkthrough from learning design patterns that Apex can offer us, to implementing the appropriate ones in your own application. Furthermore, we learn about the creational patterns that deal with object creation mechanism and structural patterns that helps to identify the relationship between entities. Also, the behavioural and concurrency patterns are put forward explaining the communication between objects and multi-threaded programming paradigm respectively. We later on, deal with the issues regarding structuring of classes, instantiating or how to give a dynamic behaviour at a runtime, with the help of anti-patterns. We learn the basic OOPs principal in polymorphic and modular way to enhance its capability. Also, best practices of writing Apex code are explained to differentiate between the implementation of appropriate patterns. This book will also explain some unique patterns that could be applied to get around governor limits. By the end of this book, you will be a maestro in developing your applications on Force.com for Salesforce Style and approach This book is a step-by-step guide, complete with well-tested programs and real world situations to solve your common occurring problems in Apex design by using the anti-patterns. It gets crackling from exploring every appropriate solution to comparing the best one as per OOps principal.

Book Description
Following hard on the explosion of British punk, in 1979 Gang of Four produced post-punk's smartest record, Entertainment! For the first time, a band wedded punk's angry energy to funk's propulsive beats-and used that music to put across lyrics that brought a heady mixture of Marxist theory and situationism to exposing the cultural politics of everyday life. But for an American college student from the suburbs-and, one expects, for many, many others, including British youth-Jon King's and Andy Gill's mumbled lyrics were often all but unintelligible. Political rock 'n' roll is always something of an oxymoron: rock audiences by and large don't tune in to be lectured to. But what can it mean that a band that made pop songs as political theory actively resisted making that theory legible? Coming to terms with the impact of Entertainment! requires us to take the mondegreen-the misunderstood lyric-seriously. The old joke has it that the title of R.E.M.'s debut album should have been not Murmur, but Mumble: true, so far as it goes. But that's the title, too, of rock 'n' roll's Greatest Hits compilation-and that strategic inarticulateness itself, which creates such an important role for the listener, has an important politics.

Book Description
This book launches an ambitious reexamination of the elite politics behind one of the most remarkable transformations in the late twentieth century. As the first part of a new interpretation of the evolution of Chinese politics during the years 1972-82, it provides a detailed study of the end of the Maoist era, demonstrating Mao's continuing dominance even as his ability to control events ebbed away. The tensions within the "gang of four," the different treatment of Zhou Enlai and Deng Xiaoping, and the largely unexamined role of younger radicals are analyzed to reveal a view of the dynamic of elite politics that is at odds with accepted scholarship. The authors draw upon newly available documentary sources and extensive interviews with Chinese participants and historians to develop their challenging interpretation of one of the most poorly understood periods in the history of the People's Republic of China.

Book Description
Praise for Design Patterns in Ruby "Design Patterns in Ruby documents smart ways to resolve many problems that Ruby developers commonly encounter. Russ Olsen has done a great job of selecting classic patterns and augmenting these with newer patterns that have special relevance for Ruby. He clearly explains each idea, making a wealth of experience available to Ruby developers for their own daily work." —Steve Metsker, Managing Consultant with Dominion Digital, Inc. "This book provides a great demonstration of the key 'Gang of Four' design patterns without resorting to overly technical explanations. Written in a precise, yet almost informal style, this book covers enough ground that even those without prior exposure to design patterns will soon feel confident applying them using Ruby. Olsen has done a great job to make a book about a classically 'dry' subject into such an engaging and even occasionally humorous read." —Peter Cooper "This book renewed my interest in understanding patterns after a decade of good intentions. Russ picked the most useful patterns for Ruby and introduced them in a straightforward and logical manner, going beyond the GoF's patterns. This book has improved my use of Ruby, and encouraged me to blow off the dust covering the GoF book." —Mike Stok "Design Patterns in Ruby is a great way for programmers from statically typed objectoriented languages to learn how design patterns appear in a more dynamic, flexible language like Ruby." —Rob Sanheim, Ruby Ninja, Relevance Most design pattern books are based on C++ and Java. But Ruby is different—and the language's unique qualities make design patterns easier to implement and use. In this book, Russ Olsen demonstrates how to combine Ruby's power and elegance with patterns, and write more sophisticated, effective software with far fewer lines of code. After reviewing the history, concepts, and goals of design patterns, Olsen offers a quick tour of the Ruby language—enough to allow any experienced software developer to immediately utilize patterns with Ruby. The book especially calls attention to Ruby features that simplify the use of patterns, including dynamic typing, code closures, and "mixins" for easier code reuse. Fourteen of the classic "Gang of Four" patterns are considered from the Ruby point of view, explaining what problems each pattern solves, discussing whether traditional implementations make sense in the Ruby environment, and introducing Ruby-specific improvements. You'll discover opportunities to implement patterns in just one or two lines of code, instead of the endlessly repeated boilerplate that conventional languages often require. Design Patterns in Ruby also identifies innovative new patterns that have emerged from the Ruby community. These include ways to create custom objects with metaprogramming, as well as the ambitious Rails-based "Convention Over Configuration" pattern, designed to help integrate entire applications and frameworks. Engaging, practical, and accessible, Design Patterns in Ruby will help you build better software while making your Ruby programming experience more rewarding.

Book Description
Scala is a new and exciting programming language that is a hybrid between object oriented languages such as Java and functional languages such as Haskell. As such it has its own programming idioms and development styles. Scala Design Patterns looks at how code reuse can be successfully achieved in Scala. A major aspect of this is the reinterpretation of the original Gang of Four design patterns in terms of Scala and its language structures (that is the use of Traits, Classes, Objects and Functions). It includes an exploration of functional design patterns and considers how these can be interpreted in Scala's uniquely hybrid style. A key aspect of the book is the many code examples that accompany each design pattern, allowing the reader to understand not just the design pattern but also to explore powerful and flexible Scala language features. Including numerous source code examples, this book will be of value to professionals and practitioners working in the field of software engineering.
