With this hands-on guide, you'll learn how to write effective, idiomatic Python code by leveraging its best and possibly most neglected features. Author Luciano Ramalho takes you through Python's core language features and libraries, and shows you how to make your code shorter, faster, and more readable at the same time.Many experienced programmers try to bend Python to fit patterns they learned from other languages, and never discover Python features outside of their experience. With this book, those Python programmers will thoroughly learn how to become proficient in Python 3.This book covers:Python data model: understand how special methods are the key to the consistent behavior of objectsData structures: take full advantage of built-in types, and understand the text vs bytes duality in the Unicode ageFunctions as objects: view Python functions as first-class objects, and understand how this affects popular design patternsObject-oriented idioms: build classes by learning about references, mutability, interfaces, operator overloading, and multiple inheritanceControl flow: leverage context managers, generators, coroutines, and concurrency with the concurrent.futures and asyncio packagesMetaprogramming: understand how properties, attribute descriptors, class decorators, and metaclasses work"

    John, Virgin Islands. It tells you exactly where to go, how to get there, and what to do and see when you arrive.

Best Selling St John Guidebook since 1994. Updated in 2009.

    No one would foresee that the greatest success story to arise from these events would be the globalization of organized crime. "McMafia" is a fearless, encompassing, wholly authoritative investigation of the now proven ability of organized crime worldwide to find and service markets driven by a seemingly insatiable demand for illegal wares. Whether discussing the Russian mafia, Colombian drug cartels, or Chinese labor smugglers, Misha Glenny makes clear how organized crime feeds off the poverty of the developing world, how it exploits new technology in the forms of cybercrime and identity theft, and how both global crime and terror are fueled by an identical source: the triumphant material affluence of the West. To trace the disparate strands of this hydra-like story, Glenny talked to police, victims, politicians, and members of the global underworld in eastern Europe, North and South America, Africa, the Middle East, China, Japan, and India. The story of organized crime's phenomenal, often shocking growth is truly the central political story of our time. "McMafia "will change the way we look at the world.

    But ever wonder who's pulling their strings? Who the movers and shakers are around the globe?

    One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.

    Just about everyone has at least heard of Albert Einstein's formulation of 1905, which came into the world as something of an afterthought. But far fewer can explain his insightful linkage of energy to mass. David Bodanis offers an easily grasped gloss on the equation. Mass, he writes, "is simply the ultimate type of condensed or concentrated energy," whereas energy "is what billows out as an alternate form of mass under the right circumstances." Just what those circumstances are occupies much of Bodanis's book, which pays homage to Einstein and, just as important, to predecessors such as Maxwell, Faraday, and Lavoisier, who are not as well known as Einstein today. Balancing writerly energy and scholarly weight, Bodanis offers a primer in modern physics and cosmology, explaining that the universe today is an expression of mass that will, in some vastly distant future, one day slide back to the energy side of the equation, replacing the "dominion of matter" with "a great stillness"--a vision that is at once lovely and profoundly frightening. Without sliding into easy psychobiography, Bodanis explores other circumstances as well; namely, Einstein's background and character, which combined with a sterling intelligence to afford him an idiosyncratic view of the way things work--a view that would change the world. --Gregory McNamee

    In the dry language of development reports and economic projections, the true misery of the 312 million who live below the poverty line, or the 26 million displaced by various projects, or the 13 million who suffer from tuberculosis gets overlooked. In this thoroughly researched study of the poorest of the poor, we get to see how they manage, what sustains them, and the efforts, often ludicrous, to do something for them. The people who figure in this book typify the lives and aspirations of a large section of Indian society, and their stories present us with the true face of development.

    Arguing that the processes creating the technium are akin to those of biological evolution, Kelly devotes the opening sections of his exposition to that analogy, maintaining that the technium exhibits a similar tendency toward self-organizing complexity. Having defined the technium, Kelly addresses its discontents, as expressed by the Unabomber (although Kelly admits to trepidation in taking seriously the antitechnology screeds of a murderer) and then as lived by the allegedly technophobic Amish. From his observations and discussions with some Amish people, Kelly extracts some precepts of their attitudes toward gadgets, suggesting folk in the secular world can benefit from the Amish approach of treating tools as servants of self and society rather than as out-of-control masters. Exploring ramifications of technology on human welfare and achievement, Kelly arrives at an optimistic outlook that will interest many, coming, as it does, from the former editor of Wired magazine."Gilbert Taylor, Booklist

    This book draws on material Michael created for his renowned Object Mentor seminars, techniques Michael has used in mentoring to help hundreds of developers, technical managers, and testers bring their legacy systems under control. The topics covered include: Understanding the mechanics of software change, adding features, fixing bugs, improving design, optimizing performance Getting legacy code into a test harness Writing tests that protect you against introducing new problems Techniques that can be used with any language or platform, with examples in Java, C++, C, and C# Accurately identifying where code changes need to be made Coping with legacy systems that aren't object-oriented Handling applications that don't seem to have any structureThis book also includes a catalog of twenty-four dependency-breaking techniques that help you work with program elements in isolation and make safer changes.

    The authors help students learn key sociological concepts through real research examples related to the dynamic interplay of race, class, gender, and other social variables.

    Metaphor, the authors explain, is a fundamental mechanism of mind, one that allows us to use what we know about our physical and social experience to provide understanding of countless other subjects. Because such metaphors structure our most basic understandings of our experience, they are "metaphors we live by", metaphors that can shape our perceptions and actions without our ever noticing them.In this updated edition of Lakoff and Johnson's influential book, the authors supply an afterword surveying how their theory of metaphor has developed within the cognitive sciences to become central to the contemporary understanding of how we think and how we express our thoughts in language.
