This outrageous and inventive short story is not just focused solely on crap itself, but the spirituality of crap. This parody of the Tao Te Ching begs the question: Is everything crap? McFergus translates Li Chang's master work from an ancient roll of toilet paper, a minor Chinese national treasure purchased on eBay, to uncover the lost legend of Li Chang.DISCLAIMER: There is no Winnie the Pooh bear in this story. There is no piglet. The only honey pot in this story has crap in it. THIS IS NOT THE TAO OF POOH.

    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.

    My grandfather, my father, Maria Eugenia, my sister, were all considered mad and I was as well. The reason was that we took a different path to everybody else.'Rafael Bielsa, Marcelo's brother, Foreign Secretary of Argentina, 2003-05. Marcelo Bielsa is one of football's greatest eccentrics and greatest enigmas. He is described by Pep Guardiola as: 'the greatest football manager in the world'. To the Tottenham manager, Mauricio Pochettino, he is 'my footballing father, the reason I became a player, the reason I became a manager.' This will be the first English biography of one of football's most contradictory characters. This is a definitive and comprehensive biography from growing up in Argentina under a military dictatorship to reviving the stricken power of Leeds United.

    All of a sudden, he found himself falling back into the old religious devotions of an earlier time. The meaning he had found through years of engagement with therapy began to dissolve. Here, in On Tuesdays I'm a Buddhist, Harding examines the search for meaning in life which keeps him fastened to the idea of god. After many therapy sessions focused on an effort to uncover personal truth, and long solitary months on the road with a one man show, Harding is finally led to an artists' retreat in the shadow of Skellig Michael.Mixing stories from the road with dispatches from his Irish Times columns, On Tuesdays I'm a Buddhist is a spell-binding and powerful book about the human condition, the narratives we weave around the self, and the ultimate bliss of living in the present moment. 'What happens between one story and the next? That's the really interesting part. That's the space where we find bliss; where we float sometimes, suspended, and only for a brief moment. Perhaps only for a few scarce moments in an entire life.'

    if you want to understand how the concept of life is changing, read this' Professor Andrew Briggs, University of OxfordWhen Darwin set out to explain the origin of species, he made no attempt to answer the deeper question: what is life? For generations, scientists have struggled to make sense of this fundamental question. Life really does look like magic: even a humble bacterium accomplishes things so dazzling that no human engineer can match it. And yet, huge advances in molecular biology over the past few decades have served only to deepen the mystery. So can life be explained by known physics and chemistry, or do we need something fundamentally new?In this penetrating and wide-ranging new analysis, world-renowned physicist and science communicator Paul Davies searches for answers in a field so new and fast-moving that it lacks a name, a domain where computing, chemistry, quantum physics and nanotechnology intersect. At the heart of these diverse fields, Davies explains, is the concept of information: a quantity with the power to unify biology with physics, transform technology and medicine, and even to illuminate the age-old question of whether we are alone in the universe.From life's murky origins to the microscopic engines that run the cells of our bodies, The Demon in the Machine is a breath-taking journey across the landscape of physics, biology, logic and computing. Weaving together cancer and consciousness, two-headed worms and bird navigation, Davies reveals how biological organisms garner and process information to conjure order out of chaos, opening a window on the secret of life itself.

    It is difficult to think about law, politics, religion, public policy, intimate relationships, morality—as well as feelings of remorse or personal achievement—without first imagining that every person is the true source of his or her thoughts and actions. And yet the facts tell us that free will is an illusion.In this enlightening book, Sam Harris argues that this truth about the human mind does not undermine morality or diminish the importance of social and political freedom, but it can and should change the way we think about some of the most important questions in life.

    Hailed as the father of modern anatomy and neurobiology, he was largely responsible for the modern conception of the brain. His groundbreaking works were New Ideas on the Structure of the Nervous System and Histology of the Nervous System in Man and Vertebrates. In addition to leaving a legacy of unparalleled scientific research, Cajal sought to educate the novice scientist about how science was done and how he thought it should be done. This recently rediscovered classic, first published in 1897, is an anecdotal guide for the perplexed new investigator as well as a refreshing resource for the old pro.Cajal was a pragmatist, aware of the pitfalls of being too idealistic--and he had a sense of humor, particularly evident in his diagnoses of various stereotypes of eccentric scientists. The book covers everything from valuable personality traits for an investigator to social factors conducive to scientific work.

     Neural networks are a key element of deep learning and artificial intelligence, which today is capable of some truly impressive feats. Yet too few really understand how neural networks actually work. This guide will take you on a fun and unhurried journey, starting from very simple ideas, and gradually building up an understanding of how neural networks work. You won't need any mathematics beyond secondary school, and an accessible introduction to calculus is also included. The ambition of this guide is to make neural networks as accessible as possible to as many readers as possible - there are enough texts for advanced readers already! You'll learn to code in Python and make your own neural network, teaching it to recognise human handwritten numbers, and performing as well as professionally developed networks. Part 1 is about ideas. We introduce the mathematical ideas underlying the neural networks, gently with lots of illustrations and examples. Part 2 is practical. We introduce the popular and easy to learn Python programming language, and gradually builds up a neural network which can learn to recognise human handwritten numbers, easily getting it to perform as well as networks made by professionals. Part 3 extends these ideas further. We push the performance of our neural network to an industry leading 98% using only simple ideas and code, test the network on your own handwriting, take a privileged peek inside the mysterious mind of a neural network, and even get it all working on a Raspberry Pi. All the code in this has been tested to work on a Raspberry Pi Zero.

    It brings comfort, purpose, and sense of pride. These feelings mean so much to the Christian. But are these feelings justified? Do Christians have good reason to trust the truth of their beliefs?
