The Rails framework empowers developers with unprecedented levels of productivity by embracing principles such as “convention over configuration” and “don’t repeat yourself”. This paradigm is even apparent at the community level, where developers regularly share their custom framework extensions by way of Rails’ plugins feature. Plugins offer a way for developers to extend the core Rails framework with their own custom features, allowing for rapid integration of features such as authentication, user ratings, and search. Practical Rails Plugins shows you how to capitalize upon the wide variety of plugins at your disposal by guiding you through their integration into a number of interesting projects. You’ll learn how to rapidly augment projects involving asynchronous video transcoding, geocoding and mapping, content management, community ratings, and PDF generation. You’ll also learn how to create and distribute your own plugins. The ultimate guide to building powerful web sites faster using Rails plugins Demonstrates how to use popular plugins within a number of practical (and fully functional) projects and mini–applications Shows you how to create and distribute your own plugins
Winners Take All meets Nickel and Dimed: a provocative debunking of accepted wisdom, providing the pathway to a sustainable, survivable economy. Confronted by the terrifying trends of the early twenty-first century – widening inequality, environmental destruction, and the immiseration of millions of workers around the world – many economists and business leaders still preach dogmas that lack evidence and create political catastrophe: Private markets are always more efficient than public ones; investment capital flows efficiently to necessary projects; massive inequality is the unavoidable side effect of economic growth; people are selfish and will only behave well with the right incentives. But a growing number of people – academic economists, business owners, policy entrepreneurs, and ordinary people – are rejecting these myths and reshaping economies around the world to reflect ethical and social values. Though they differ in approach, all share a vision of the economy as a place of moral action and accountability. Journalist Nick Romeo has spent years covering the world’s most innovative economic and policy ideas for The New Yorker. Romeo takes us on an extraordinary journey through the unforgettable stories and successes of people working to build economies that are more equal, just, and livable. Combining original, in-depth reporting with expert analysis, Romeo explores: The successful business owners organizing their companies as purpose trusts (as Patagonia recently did) to fulfill a higher mission, such as sharing profits with workers or protecting the environment The growing deployment of new models by venture capital funds to promote wealth creation for the poorest Americans and address climate change. How Oslo’s climate budgeting program is achieving the emission reduction targets the rest of the world continues to miss, creating a model that will soon be emulated by governments around the world How Portugal strengths democratic culture by letting citizens make crucial budget decisions The way worker ownership and cooperatives foster innovation, share wealth, and improve the quality of jobs, offering an increasingly popular model superior to the traditional corporation The public-sector marketplace that offers decent work and real protections to gig workers in California The job guarantee program in southern Austria that offers high-quality meaningful jobs to every citizen Many books have exposed what’s not working in our current system. Romeo reveals something even more essential: the structure of a system that could actually work for everyone. Margaret Thatcher was wrong: there is an alternative. This is what it looks like.
In the 4700 years since its first recorded use, cannabis has been respected as a highly useful source of fibre, food and medicine and vilified as a social menace. Society in the 21st century seems to be of both opinions: doctors spend millions exploiting its medicinal value and thousands of people travel to Amsterdam each weekend to sit in cafes to smoke copious amounts of dope free from molestation, yet taking less than 30g (1oz) back into their own countries is an offence and public figures who admit to smoking cannabis in their youth claim that they did so without inhaling. This Is Cannabis does not preach the benefits or the deficits of cannabis; instead, it aims to provide the facts about cannabis in an authoritative, straightforward way, outlining the history, laws, and culture that have accreted around it, its effects on health, and the booming commercial potential.
The psychological health of competitive athletes is of paramount importance to performance, retention, and well-being in sport, and national governing bodies are increasingly concerned with its promotion. Psychosocial Health and Well-being in High-Level Athletes offers students, researchers, and practicing sport psychologists an accessible and rigorous grounding in the manifestations of psychosocial health in athletes, the threats athletes face to their psychosocial health, and the interventions which can be designed to enhance it. Seeking to guide future research and expand professional understanding of psychosocial issues in sport, the book is based on a model of cognitive, emotional, social, and spiritual health. It clearly defines these dimensions in a sporting context before discussing pertinent threats—such as career transitions, injuries and abuse—and interventions, including adversarial growth, life-skill interventions, prevention and organization policy, and mindfulness-based interventions. Providing an innovative and integrated perspective on psychosocial health and well-being in competitive sport, this book is essential reading for upper-level students taking any clincial sport psychology modules, and for sport psychologists, coaches, and administrators working with competitive athletes.
Until the publication of the first edition of 'Star Maps,' books were either general histories of astronomy using examples of antiquarian celestial maps as illustrations, or catalogs of celestial atlases that failed to trace the flow of sky map development over time. The second edition focuses on the development of contemporary views of the heavens and advances in map-making. It captures the beauty and awe of the heavens through images from antiquarian celestial prints and star atlases. This book uniquely combines a number of features: 1) the history of celestial cartography is traced from ancient to modern times; 2) this development is integrated with contemporary cosmological systems; 3) the artistry of sky maps is shown using beautiful color images from actual celestial atlases and prints; 4) each illustration is accompanied by a legend explaining what is being shown; and 5) the text is written for the lay reader based on the author's experience with writing articles for amateur astronomy and map collector magazines. This updated second edition of 'Star Maps' contains over 50 new pages of text and 44 new images (16 in color), including completely new sections on celestial frontispieces, deep-sky objects, playing card maps, additional cartographers, and modern computerized star maps. There is also expanded material about celestial globes, volvelles, telescopes, and planets and asteroids.

This is a book about sustainable design, by the leading sustainable design thinkers, for creative practitioners, professionals, students and academics. This challenging work provides the reader with a rich resource of future visions, critical propositions, creative ideas and design strategies for working towards a sustainable tomorrow, today. The authors boldly present alternative understandings of sustainable design, to curate a challenging, sometimes uncomfortable and always provocative, collection of essays by some of the worlds leading sustainable design thinkers. The result is an impacting and polemical anthology that reinvigorates the culture of critique that, in previous years, has empowered design with the qualities of social, environmental and economic revolution.
First published in 1976, this book tells of the dramatic struggle between tenants' groups, community associations, students, squatters, intellectuals, political parties, and property developers at Tolmers Square in north London. The author describes how property developers, interested only in maximising profits, attempted to redevelop the Tolmers area for offices, while the local authority, pressurised by local tenants and faced with a housing shortage, tried to redevelop for housing. This book is about the politics of central city redevelopment. Although this text focuses on one particular case study, the same processes operate in all cities where land is used as a commodity for financial speculation. By tracing the Tolmers case in detail, this text demonstrates the forces which operate in city redevelopment, and shows the affect which various forms of opposition can have.

The Price of Slavery analyzes Marx’s critique of capitalist slavery and its implications for the Caribbean thought of Toussaint Louverture, Henry Christophe, C. L. R. James, Aimé Césaire, Jacques Stephen Alexis, and Suzanne Césaire. Nick Nesbitt assesses the limitations of the literature on capitalism and slavery since Eric Williams in light of Marx’s key concept of the social forms of labor, wealth, and value. To do so, Nesbitt systematically reconstructs for the first time Marx’s analysis of capitalist slavery across the three volumes of Capital. The book then follows the legacy of Caribbean critique in its reflections on the social forms of labor, servitude, and freedom, as they culminate in the vehement call for the revolutionary transformation of an unjust colonial order into one of universal justice and equality.
Typically one third of the energy used in many buildings may be consumed by electric lighting. Good daylighting design can reduce electricity consumption for lighting and improve standards of visual comfort, health and amenity for the occupants.As the only comprehensive text on the subject written in the last decade, the book will be welcomed by all architects and building services engineers interested in good daylighting design. The book is based on the work of 25 experts from all parts of Europe who have collected, evaluated and developed the material under the auspices of the European Commission's Solar Energy and Energy Conservation R&D Programmes.

IT had rained in torrents all the way down from Schenectady, so when Jack Duane glimpsed the lights of what looked to be a big house through the trees, he braked his battered, convertible sedan to a stop at the side of the road. Mud lay along the fenders and running boards; mud and water had spumed up and freckled Duane’s face and hat. He pulled off the latter—it was soggy—and slapped it on the seat beside him, leaning out and squinting through the darkness and falling water. He was on the last lap of a two weeks’ journey from San Francisco, his objective being New York City. There he hoped to wangle a job as foreign correspondent from an old crony, J. J. Molloy, now editor of the New York Globe. Adventurer, journalist, globetrotter, Duane was of the type that is always on the move. “It’s a place, anyway, Moses,” he said to the large black man beside him, his servitor and bodyguard, who had accompanied him everywhere for the past three years. “Somebody lives there; they ought to have some gas.” “Yasah,” said Moses, staring past Duane’s shoulder, “it’s a funny-looking place, suh.” Duane agreed. Considering that they were seventy miles from New York, in the foothills of the Catskills, with woods all around them and the rain pouring down, the thing they saw through the trees, some three hundred yards from the country road, was indeed peculiar. It looked more like a couple of Pullman cars coupled together and lighted, than like a farmer’s dwelling. “Fenced in, too,” said Duane, pointing to the high steel fence that bordered the road, separating them from the object of their vision. “And look there—” A fitful flash of lightning in the east, illuminating the distant treetops, showed up the towering steel and network of a high-voltage electric line’s tower. The roving journalist muttered something to express his puzzlement, and got out of the car. Moses followed him. “Well,” said Duane presently, when they had stared a moment longer, “whatever it is, I’m barging in. We’ve got to have some gas or we’ll never make New York tonight.” MOSES agreed. The two men started across the road—the big Negro hatless and wearing a slicker—the reporter in a belted trench coat, his brown felt hat pulled out of shape on his head. “It’s a big thing,” Duane said as he and Moses halted at the fence and peered through. Distantly, he could see now that the mysterious structure in the woods was at least a hundred yards long, flat-topped and black as coal except from narrow shafts of light that came from its windows. “And look at the light coming out of the roof.” That was, indeed, the most peculiar feature of this place they had discovered. From a section of the roof near the center, as though through a skylight, a great white light came out, illuminating the slanting rain and the bending trees.
