Hex Highway

Investigates the possible meanings of hex-sign barn decorations, both historically and at the present.

The traditional Pennsylvania Dutch folk practice of painting colorful, round geometric designs directly on barns was adapted to a detached disk format in the mid-twentieth century. Ivan E. Hoyt is one of the most celebrated artisans of hex sign painting, and in this detailed how-to book he shares his knowledge, providing information on tools, step-by-step instructions and photographs, design ideas, and painting tips. Projects include rosette, star, tulip, maple, and oak designs.

Fully revised and updated edition. Filled with all-new vintage postcards and photos. Maps for travelers following the original route.

"This book shows many of [The William Penn Highway's] scenic and historic sites"--Back cover.

Have you driven along historic Route 6 or through the rolling farmlands of Pennsylvania Dutch country and the popular Amish Lancaster County? Have you explored the battlefields of Gettysburg or the disappearing wilderness of the Poconos and the Appalachian mountains? Have you truly experienced the Susquehanna River? A celebration of our state's beauty, Backroads of Pennsylvania--written and photographed by local experts--takes you on routes covering nearly all corners of the Keystone State: routes that lead you to the state's most secluded and overlooked natural areas and sites that capture Pennsylvania's colorful history. Whether you're planning a day trip, looking for unusual destinations, or simply want to learn more about the region, Backroads of Pennsylvania will lead you deep into the soul of the state-beyond the bustling cities and common tourist attractions. Glenn Davis's Davis Photographic Specialties focuses on natural history photography and commercial advertising. His photography has appeared in many national publications, including Audubon, National Geographic, and Natural History magazines, Sierra Club calendars, and Hallmark cards.

Past, Present, Parallel is a survey of the current state of the parallel processing industry. In the early 1980s, parallel computers were generally regarded as academic curiosities whose natural environment was the research laboratory. Today, parallelism is being used by every major computer manufacturer, although in very different ways, to produce increasingly powerful and cost-effec- tive machines. The first chapter introduces the basic concepts of parallel computing; the subsequent chapters cover different forms of parallelism, including descriptions of vector supercomputers, SIMD computers, shared memory multiprocessors, hypercubes, and transputer-based machines. Each section concentrates on a different manufacturer, detailing its history and company profile, the machines it currently produces, the software environments it supports, the market segment it is targetting, and its future plans. Supplementary chapters describe some of the companies which have been unsuccessful, and discuss a number of the common software systems which have been developed to make parallel computers more usable. The appendices describe the technologies which underpin parallelism. Past, Present, Parallel is an invaluable reference work, providing up-to-date material for commercial computer users and manufacturers, and for researchers and postgraduate students with an interest in parallel computing.
