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

    If trouble comes calling, Carlton isn't afraid to let his fists do the talking and woe betide anyone who crosses him, or those close to him. At last Carlton gives the full account of his life including how his story has been made into a hugely successful film. Born and raised in East London, Carlton was a key member of the notorious Essex Boys gang and the West Ham InterCity Firm, one of the most violent hooligan gangs to trouble the football terraces during the 1980s. He's been shot at, stabbed, glassed—he's even had an axe in his head. Yet the event that really brought turmoil into his life was the murder of his best friend in the infamous Range Rover murders. Carlton vowed that he would find those responsible and make them pay. There isn't much that Carlton hasn't seen or experienced in his life and his tales of violence, gang wars and close calls with death will have you on the edge of your seat. He knows how close he has come to dying and has therefore shut the door on a gangland life. He may have changed but, as he himself says, "I'll always need to exercise the Carlton Leach brand of justice. It's in me."

    The Lean Startup movement is very promising, but for many teams it ends up translating into an important question: ”Yeah, but what to build ?” “In ThoughtWorks, our response has been a process called an inception. We gather together a good sample of the people who will be affected by the product and have an intensive session to set an initial direction, using a series of exercises focusing on collaboration and the capture of broad goals. We don't attempt a detailed specification, as that is exactly the kind of thing that becomes out of date as soon as code hits production. But we do want to understand what kind of outcomes we are hoping for, the features that we think will drive these outcomes, and how to assess the effectiveness of our product. With The Lean Inception, Paulo has captured his experience in running these inceptions over the last decade. In particular it's focused on his work to boil the inception down to its essence, concentrating the activity on a single, if very intensive, week of work. Paulo shares how he makes this work, through writing a product vision, capturing personas, understanding the user journeys, and developing high-level features. The result isn't a detailed plan of work, which we find quickly rots into irrelevance. It is a guiding set of goals to set us off in the right direction. It doesn't plan out a final product, with all the features that our users will need, instead it focuses on an initial product that we can release and learn from - the Minimum Viable Product. “ – Martin Fowler, Chief Cientist at ThoughtWorks

    Infrastructure engineers use a software version of this “chaos monkey” to test online services’ robustness—their ability to survive random failure and correct mistakes before they actually occur. Tech entrepreneurs are society’s chaos monkeys, disruptors testing and transforming every aspect of our lives, from transportation (Uber) and lodging (AirBnB) to television (Netflix) and dating (Tinder). One of Silicon Valley’s most audacious chaos monkeys is Antonio García Martínez.After stints on Wall Street and as CEO of his own startup, García Martínez joined Facebook’s nascent advertising team, turning its users’ data into profit for COO Sheryl Sandberg and chairman and CEO Mark “Zuck” Zuckerberg. Forced out in the wake of an internal product war over the future of the company’s monetization strategy, García Martínez eventually landed at rival Twitter. He also fathered two children with a woman he barely knew, committed lewd acts and brewed illegal beer on the Facebook campus (accidentally flooding Zuckerberg's desk), lived on a sailboat, raced sport cars on the 101, and enthusiastically pursued the life of an overpaid Silicon Valley wastrel.Now, this gleeful contrarian unravels the chaotic evolution of social media and online marketing and reveals how it is invading our lives and shaping our future. Weighing in on everything from startups and credit derivatives to Big Brother and data tracking, social media monetization and digital “privacy,” García Martínez shares his scathing observations and outrageous antics, taking us on a humorous, subversive tour of the fascinatingly insular tech industry. Chaos Monkeys lays bare the hijinks, trade secrets, and power plays of the visionaries, grunts, sociopaths, opportunists, accidental tourists, and money cowboys who are revolutionizing our world. The question is, will we survive?

    His heroic legacy of being shot down while preparing to rescue a fallen teammate began long before this tragic day.An Apache aviator said of Mark's final battle: ..."I have never witnessed such an act of heroism in my three years of fighting in combat. I have over 2,700 hours total time with 1,500 hours of combat time in both Iraq and Afghanistan...JAG 28 continued to advance on the enemy while taking intense enemy fire, and continuously fired his weapon in an attempt to get to his fallen teammate and destroy the enemy."Mark chose to enlist in the Air Force as a Special Operations Combat Controller after he received his Bachelor's degree from The University of Alabama. Because of his above average grades and near-photographic memory, his Business Finance degree would have done him well. But, he felt a higher calling; one that put him between us and the enemies bent on our destruction.Even though he had pledged that freedom must be preserved, his greatest desire was to marry the right girl and have a family-Mark never got that chance. Instead he selflessly gave his life for the country he loved.Since Mark's death, his family's eyes and hearts have been opened to multiple examples of selflessness and patriotism by meeting his teammates and leaders in the military. The family has witnessed first-hand the ability for them to turn off their stern, professional personae and turn on compassion, love, support and acceptance. The author feels a strong desire to Honor our Heroes. This book highlights one hero, SrA Mark A. Forester, and also helps recognize many other men and women who volunteer to fight for our freedom.My Brother in Arms is not a memorial in print, but a biography for continuing Mark's legacy of perseverance, determination and accomplishing our missions on earth.
