Each day, Bob Sheasley leaves Lilyfield Farm and heads into the city. And each day, he brings along a basket of eggs for his coworkers at The Philadelphia Inquirer. Depending on the breed of hen, these eggs may be white, green, rose, blue, or as brown as chocolate. And they are all deliciously fresh, a taste of the rural way of life that people have enjoyed for millennia, one in which chickens have played a supporting role for nearly as long. In Home to Roost, Sheasley tells of the intertwined relationship between humans and chickens. He delves into where chickens came from, what their DNA tells us about our kinship, how we’ve treated our feathered fellow travelers, and the roads we’re crossing together. This is a story of agriculture and human migration, of folk medicine and technology, of how we dreamed of the good life, threw it away, and want it back. Modern farming has changed the lives of both bird and man over the past century. But backyard farmers like Sheasley offer hope for a return to the pleasures of locally grown food, as diverse as the chickens he’s raised on Lilyfield Farm. With wit and personal insight, Home to Roost examines of how our lives can be changed for the better, with something as simple as a backyard coop.

A haunting, magical novel about joy, grief, courage and transformation from the international bestselling author of The Lost Flowers of Alice Hart. ‘On the afternoon that Esther Wilding drove homeward along the coast, a year after her sister had walked into the sea and disappeared, the light was painfully golden.’ The last time Esther Wilding’s beloved older sister Aura was seen, she was walking along the shore towards the sea. In the wake of Aura’s disappearance, Esther’s family struggles to live with their loss. To seek the truth about her sister’s death, Esther reluctantly travels from Lutruwita/Tasmania, to Copenhagen, and then to the Faroe Islands, following the trail of the stories Aura left behind: seven fairy tales about selkies, swans and women, alongside cryptic verses Aura wrote and had secretly tattooed on her body. The Seven Skins of Esther Wilding is a sweeping, deeply beautiful and profoundly moving novel about the far reaches of sisterly love, the power of wearing your heart on your skin and the ways life can transform when we find the courage to feel the fullness of both grief and joy.

This engaging and clearly written textbook/reference provides a must-have introduction to the rapidly emerging interdisciplinary field of data science. It focuses on the principles fundamental to becoming a good data scientist and the key skills needed to build systems for collecting, analyzing, and interpreting data. The Data Science Design Manual is a source of practical insights that highlights what really matters in analyzing data, and provides an intuitive understanding of how these core concepts can be used. The book does not emphasize any particular programming language or suite of data-analysis tools, focusing instead on high-level discussion of important design principles. This easy-to-read text ideally serves the needs of undergraduate and early graduate students embarking on an “Introduction to Data Science” course. It reveals how this discipline sits at the intersection of statistics, computer science, and machine learning, with a distinct heft and character of its own. Practitioners in these and related fields will find this book perfect for self-study as well. Additional learning tools: Contains “War Stories,” offering perspectives on how data science applies in the real world Includes “Homework Problems,” providing a wide range of exercises and projects for self-study Provides a complete set of lecture slides and online video lectures at www.data-manual.com Provides “Take-Home Lessons,” emphasizing the big-picture concepts to learn from each chapter Recommends exciting “Kaggle Challenges” from the online platform Kaggle Highlights “False Starts,” revealing the subtle reasons why certain approaches fail Offers examples taken from the data science television show “The Quant Shop” (www.quant-shop.com)
