Paul. Now, in Once There Were Castles, he offers a richly illustrated look at another world of ghosts in our midst: the lost mansions and estates of the Twin Cities.Nobody can say for sure how many lost mansions haunt the Twin Cities, but at least five hundred can be accounted for in public records and archives. In Minneapolis and St. Paul, entire neighborhoods of luxurious homes have disappeared, virtually without a trace. Many grand estates that once spread out over hundreds of acres along the shores of Lake Minnetonka are also gone. The greatest of these lost houses often had astonishingly short lives: the lavish Charles Gates mansion in Minneapolis survived only nineteen years, and Norman Kittson’s sprawling castle on the site of the St. Paul Cathedral stood for barely more than two decades. Railroad and freeway building, commercial and institutional expansion, fires, and financial disasters all claimed their share of mansions; others succumbed to their own extravagance, becoming too costly to maintain once their original owners died.The stories of these grand houses are, above all else, the stories of those who built and lived in them—from the fantastic saga of Marion Savage to the continent-spanning conquests of James J. Hill, to the all-but-forgotten tragedy of Olaf Searle, a poor immigrant turned millionaire who found and lost a dream in the middle of Lake Minnetonka. These and many other mansion builders poured all their dreams, desires, and obsessions into extravagant homes designed to display wealth and solidify social status in a culture of ever-fluctuating class distinctions.The first book to take an in-depth look at the history of the Twin Cities’ mansions, Once There Were Castles presents ninety lost mansions and estates, organized by neighborhood and illustrated with photographs and drawings. An absorbing read for Twin Cities residents and a crucial addition to the body of work on the region’s history, Once There Were Castles brings these “ghost mansions” back to life.

    In the winter of 1913, Grand Central Station was officially opened and immediately became one of the most beautiful and recognizable Manhattan landmarks. In this celebration of the one hundred year old terminal, Sam Roberts of The New York Times looks back at Grand Central's conception, amazing history, and the far-reaching cultural effects of the station that continues to amaze tourists and shuttle busy commuters. Along the way, Roberts will explore how the Manhattan transit hub truly foreshadowed the evolution of suburban expansion in the country, and fostered the nation's westward expansion and growth via the railroad. Featuring quirky anecdotes and behind-the-scenes information, this book will allow readers to peek into the secret and unseen areas of Grand Central -- from the tunnels, to the command center, to the hidden passageways. With stories about everything from the famous movies that have used Grand Central as a location to the celestial ceiling in the main lobby (including its stunning mistake) to the homeless denizens who reside in the building's catacombs, this is a fascinating and, exciting look at a true American institution.

    In Dreams of Iron and Steel, acclaimed historian Deborah Cadbury tells the heroic tale of the visionaries and ordi-nary workers who brought to life seven wonders of engi-neering that still have the power to awe and inspire us today.From the London sewers that banished cholera to the Panama Canal that shaved thousands of miles off a dangerous sea passage, from the Hoover Dam that diverted the world's most unpredictable river to give power to over half of the country to the transcontinental railroad that fulfilled the dream of manifest destiny, Dreams of Iron and Steel reveals the epic struggles and personal stories of the most brilliant pioneers of the industrial age, and the financiers and politicians who hung on for the ride as fortunes and reputations were lost and won.Fueled by Deborah Cadbury's characteristic scholarship and insight, this extraordinary chronicle re-createsthe human odyssey of how our modern world was forged -- with rivets, grease, and steam, but also with blood, sweat, and extreme imagination.

    Reflecting the increasing demand for efficient conversion and control of electrical power, it considers the latest power devices, circuits, and control schemes that continue to extend power electronics technology to new applications areas. Presents material methodically - first establishing the background theory before going on to specific applications. Familiarizes readers with the analysis and operation of various power conversions circuits that have applications at high power levels, and formulates equations that govern the behavior of these circuits. Discusses the application of power electronic devices in uncontrolled and controlled single phase rectifiers, inverters, ac voltage controllers, cycloconverters, and dc choppers, and demonstrates voltage and current waveform analysis for the output, starting with a simple resistive load to more practical inductive loads. Includes many worked examples, basic formulas, and an abundance of illustrations and diagrams.

    As traffic volume and data demands increase, these applications become more complicated and brittle, exposing risks and compromising availability. This practical guide shows IT, devops, and system reliability managers how to prevent an application from becoming slow, inconsistent, or downright unavailable as it grows.Scaling isn't just about handling more users; it's also about managing risk and ensuring availability. Author Lee Atchison provides basic techniques for building applications that can handle huge quantities of traffic, data, and demand without affecting the quality your customers expect.In five parts, this book explores:Availability: learn techniques for building highly available applications, and for tracking and improving availability going forwardRisk management: identify, mitigate, and manage risks in your application, test your recovery/disaster plans, and build out systems that contain fewer risksServices and microservices: understand the value of services for building complicated applications that need to operate at higher scaleScaling applications: assign services to specific teams, label the criticalness of each service, and devise failure scenarios and recovery plansCloud services: understand the structure of cloud-based services, resource allocation, and service distribution

    interstate system changed the face of our country. The Big Roads charts the creation of these essential American highways. From the turn-of-the-century car racing entrepreneur who spurred the citizen-led “Good Roads” movement, to the handful of driven engineers who conceived of the interstates and how they would work—years before President Eisenhower knew the plans existed—to the protests that erupted across the nation when highways reached the cities and found people unwilling to be uprooted in the name of progress, Swift follows a winding, fascinating route through twentieth-century American life.  How did we get from dirt tracks to expressways, from main streets to off-ramps, from mud to concrete and steel, in less than a century? Through decades of politics, activism, and marvels of engineering, we recognize in our highways the wanderlust, grand scale, and conflicting notions of citizenship and progress that define America.

    

    The mills at Wicksbridge are imaginary, but their planning, construction, and operation are quite typical of mills developed in New England throughout the nineteenth century.

    Like other European cities, it was still emerging from its medieval past. But in a mere century Paris would be transformed into the modern and mythic city we know today.Though most people associate the signature characteristics of Paris with the public works of the nineteenth century, Joan DeJean demonstrates that the Parisian model for urban space was in fact invented two centuries earlier, when the first complete design for the French capital was drawn up and implemented. As a result, Paris saw many changes. It became the first city to tear down its fortifications, inviting people in rather than keeping them out. Parisian urban planning showcased new kinds of streets, including the original boulevard, as well as public parks and the earliest sidewalks and bridges without houses. Venues opened for urban entertainment of all kinds, from opera and ballet to a pastime invented in Paris, recreational shopping. Parisians enjoyed the earliest public transportation and street lighting, and Paris became Europe's first great walking city.A century of planned development made Paris both beautiful and exciting. It gave people reasons to be out in public as never before and as nowhere else. And it gave Paris its modern identity as a place that people dreamed of seeing. By 1700, Paris had become the capital that would revolutionize our conception of the city and of urban life.

    But Bella Bathurst throws a powerful, revolving light into the darkness of this historical tradition. Robert Louis was a sickly fellow, and - unlike the rest of his strong-willed, determined family - certainly not up to the astonishing rigours of lighthouse building, all of which are vividly described here. To build these towering structures in the most inhospitable places imaginable (such as the aptly named Cape Wrath), using only 19th-century technology is an achievement that beggars belief. The comparison that comes to mind is with the pyramid building of ancient Egypt. For instance, we learn that the ground rocks for the Skerryvore lighthouse were prepared by hand (even though the "gneiss could blunt a pick in three blows") in waves and winds "strong enough to lift a man bodily off the rock" and that "it took 120 hours to dress a single stone for the outside of the tower and 320 hours to dress one of the central stones. In total 5000 tons of stone were quarried and shipped" - and all by hand. It is mind-boggling stuff: you'll look at lighthouses with a new respect. - Adam Roberts

    His first tunnel trips inspired a lifelong fascination with exploring underground worlds, from the derelict subway stations and sewers of New York City to sacred caves, catacombs, tombs, bunkers, and ancient underground cities in more than twenty countries around the world. Underground is both a personal exploration of Hunt’s obsession and a panoramic study of how we are all connected to the underground, how caves and other dark hollows have frightened and enchanted us through the ages.In a narrative spanning continents and epochs, Hunt follows a cast of subterraneaphiles who have dedicated themselves to investigating underground worlds. He tracks the origins of life with a team of NASA microbiologists a mile beneath the Black Hills, camps out for three days with urban explorers in the catacombs and sewers of Paris, descends with an Aboriginal family into a 35,000-year-old mine in the Australian outback, and glimpses a sacred sculpture molded by Paleolithic artists in the depths of a cave in the Pyrenees.Each adventure is woven with findings in mythology and anthropology, natural history and neuroscience, literature and philosophy. In elegant and graceful prose, Hunt cures us of our “surface chauvinism,” opening our eyes to the planet’s hidden dimension. He reveals how the subterranean landscape gave shape to our most basic beliefs and guided how we think about ourselves as humans. At bottom, Underground is a meditation on the allure of darkness, the power of mystery, and our eternal desire to connect with what we cannot see.

    The consequences of this gathering may be enormous. In this new ebook, experts Patrick J. Michaels and Paul C. Knappenberger assess the issues sure to drive the debate before, during, and after the Paris meeting.

    Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations.Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples–all applicable to C# developers–and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment.The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals.
