The Web is awash in Ruby code that is now virtually impossible to change or extend. This text helps you solve that problem by using powerful real-world object-oriented design techniques, which it thoroughly explains using simple and practical Ruby examples. Sandi Metz has distilled a lifetime of conversations and presentations about object-oriented design into a set of Ruby-focused practices for crafting manageable, extensible, and pleasing code. She shows you how to build new applications that can survive success and repair existing applications that have become impossible to change. Each technique is illustrated with extended examples, all downloadable from the companion Web site, poodr.info. The first title to focus squarely on object-oriented Ruby application design, Practical Object-Oriented Design in Ruby will guide you to superior outcomes, whatever your previous Ruby experience. Novice Ruby programmers will find specific rules to live by; intermediate Ruby programmers will find valuable principles they can flexibly interpret and apply; and advanced Ruby programmers will find a common language they can use to lead development and guide their colleagues. This guide will help you Understand how object-oriented programming can help you craft Ruby code that is easier to maintain and upgrade Decide what belongs in a single Ruby class Avoid entangling objects that should be kept separate Define flexible interfaces among objects Reduce programming overhead costs with duck typing Successfully apply inheritance Build objects via composition Design cost-effective tests Solve common problems associated with poorly designed Ruby code

    Just four years later, Compaq was on the Fortune 500 list, and, two years after that, they had exceeded $1 billion in annual revenue. No company had ever achieved these milestones so rapidly.But few know the story behind the story. In 1982, when Compaq was founded, there was no software standardization, so every brand of personal computer required its own unique application software. Just eight years later, compatibility with the open PC standard had become ubiquitous, and it has continued to be for over two decades.This didn’t happen by accident. Cofounder and then CEO Rod Canion and his team made a series of risky and daring decisions—often facing criticism and incredulity—that allowed the open PC standard marketplace to thrive and the incredible benefits of open computing to be realized.A never-before-published insider account of Compaq’s extraordinary strategies and decisions, Open provides valuable lessons in leadership in times of crisis, management decision-making under the pressure of extraordinary growth, and the power of a unique, pervasive culture.Open tells the incredible story of Compaq’s meteoric rise from humble beginnings to become the PC industry leader in just over a decade.

    Each idiom comes with a detailed description, example code showing the "wrong" way to do it, and code for the idiomatic, "Pythonic" alternative. *This version of the book is for Python 2.7.3+. There is also a Python 3.3+ version available.* "Writing Idiomatic Python" contains the most common and important Python idioms in a format that maximizes identification and understanding. Each idiom is presented as a recommendation to write some commonly used piece of code. It is followed by an explanation of why the idiom is important. It also contains two code samples: the "Harmful" way to write it and the "Idiomatic" way. * The "Harmful" way helps you identify the idiom in your own code. * The "Idiomatic" way shows you how to easily translate that code into idiomatic Python. This book is perfect for you: * If you're coming to Python from another programming language * If you're learning Python as a first programming language * If you're looking to increase the readability, maintainability, and correctness of your Python code What is "Idiomatic" Python? Every programming language has its own idioms. Programming language idioms are nothing more than the generally accepted way of writing a certain piece of code. Consistently writing idiomatic code has a number of important benefits: * Others can read and understand your code easily * Others can maintain and enhance your code with minimal effort * Your code will contain fewer bugs * Your code will teach others to write correct code without any effort on your part

By doing so, we obscure where the real power lies.In this powerful and necessary book, James Ball sets out on a global journey into the inner workings of the system. From the computer scientists to the cable guys, the billionaire investors to the ad men, the intelligence agencies to the regulators, these are the real-life figures powering the internet and pulling the strings of our society.Ball brilliantly shows how an invention once hailed as a democratising force has concentrated power in places it already existed – that the system, in other words, remains the same as it did before.
