This is a tutorial, including screencasts, links, and code, on creating awesome command-line applications in the Ruby programming language, using the library Methadone.
We’ll walk through the creation of a simple application to manage your “dotfiles”, which are configuration files used in most UNIX and Mac systems. Along the way, we’ll learn most of the features of Methadone, as well…

Summary : 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.

Summary : A philosophical manual of media power for the network age. Evil Media develops a philosophy of media power that extends the concept of media beyond its tried and trusted use in the games of meaning, symbolism, and truth. It addresses the gray zones in which media exist as corporate work systems, algorithms and data structures, twenty-first century self-improvement manuals, and pharmaceutical techniques. Evil Media invites the reader to explore and understand the abstract infrastructure of the present day. From search engines to flirting strategies, from the value of institutional stupidity to the malicious minutiae of databases, this book shows how the devil is in the details. The title takes the imperative “Don't be evil” and asks, what would be done any differently in contemporary computational and networked media were that maxim reversed. Media here are about much more and much less than symbols, stories, information, or communication: media do things. They incite and provoke, twist and bend, leak and manage. In a series of provocative stratagems designed to be used, Evil Media sets its reader an ethical challenge: either remain a transparent intermediary in the networks and chains of communicative power or become oneself an active, transformative medium.

Summary : THE NUMBER ONE NEW YORK TIMES BESTSELLER NOW A MAJOR FILM, STARRING STEVE CARELL AND BAFTA AND GOLDEN GLOBE NOMINATED TIMOTHEE CHALAMET ‘What had happened to my beautiful boy? To our family? What did I do wrong?’ Those are the wrenching questions that haunted every moment of David Sheff’s journey through his son Nic’s addiction to drugs and tentative steps toward recovery. Before Nic Sheff became addicted to crystal meth, he was a charming boy, joyous and funny, a varsity athlete and honor student adored by his two younger siblings. After meth, he was a trembling wraith who lied, stole, and lived on the streets. With haunting candour, David Sheff traces the first subtle warning signs: the denial, the 3am phone calls (is it Nic? the police? the hospital?), the attempts at rehab. His preoccupation with Nic became an addiction in itself, and the obsessive worry and stress took a tremendous toll. But as a journalist, he instinctively researched every avenue of treatment that might save his son and refused to give up on Nic. This story is a first: a teenager's addiction from the parent's point of view – a real-time chronicle of the shocking descent into substance abuse and the gradual emergence into hope. Beautiful Boy is a fiercely candid memoir that brings immediacy to the emotional rollercoaster of loving a child who seems beyond help. Read the other side of Nic Sheff's bestselling memoir, Tweak. Praise for Beautiful Boy:- 'A brilliant, harrowing, heartbreaking, fascinating story, full of beautiful moments and hard-won wisdom. This book will save a lot of lives and heal a lot of hearts'. Anne Lamott 'An important book... moving, timely and startlingly beautiful.' Richard Branson
