Code Nation explores the rise of software development as a social, cultural, and technical phenomenon in American history. The movement germinated in government and university labs during the 1950s, gained momentum through corporate and counterculture experiments in the 1960s and 1970s, and became a broad-based computer literacy movement in the 1980s. As personal computing came to the fore, learning to program was transformed by a groundswell of popular enthusiasm, exciting new platforms, and an array of commercial practices that have been further amplified by distributed computing and the Internet. The resulting society can be depicted as a “Code Nation”—a globally-connected world that is saturated with computer technology and enchanted by software and its creation. Code Nation is a new history of personal computing that emphasizes the technical and business challenges that software developers faced when building applications for CP/M, MS-DOS, UNIX, Microsoft Windows, the Apple Macintosh, and other emerging platforms. It is a popular history of computing that explores the experiences of novice computer users, tinkerers, hackers, and power users, as well as the ideals and aspirations of leading computer scientists, engineers, educators, and entrepreneurs. Computer book and magazine publishers also played important, if overlooked, roles in the diffusion of new technical skills, and this book highlights their creative work and influence. Code Nation offers a “behind-the-scenes” look at application and operating-system programming practices, the diversity of historic computer languages, the rise of user communities, early attempts to market PC software, and the origins of “enterprise” computing systems. Code samples and over 80 historic photographs support the text. The book concludes with an assessment of contemporary efforts to teach computational thinking to young people.

The award-winning New York Times bestseller about the American women who secretly served as codebreakers during World War II--a "prodigiously researched and engrossing" (New York Times) book that "shines a light on a hidden chapter of American history" (Denver Post). Recruited by the U.S. Army and Navy from small towns and elite colleges, more than ten thousand women served as codebreakers during World War II. While their brothers and boyfriends took up arms, these women moved to Washington and learned the meticulous work of code-breaking. Their efforts shortened the war, saved countless lives, and gave them access to careers previously denied to them. A strict vow of secrecy nearly erased their efforts from history; now, through dazzling research and interviews with surviving code girls, bestselling author Liza Mundy brings to life this riveting and vital story of American courage, service, and scientific accomplishment.

XSLT is a powerful language for transforming XML documents into something else. That something else can be an HTML document, another XML document, a Portable Document Format (PDF) file, a Scalable Vector Graphics (SVG) file, a Virtual Reality Modeling Language (VRML) file, Java code, or a number of other things. You write an XSLT stylesheet to define the rules for transforming an XML document, and the XSLT processor does the work.As useful as XSLT is, its peculiar characteristics make it a difficult language in which to get started. In fact, newcomers are often a little dazed on first contact. Learning XSLT offers a hands-on introduction to help them get up to speed with XSLT quickly. The book will help web developers and designers understand this powerful but often mystifying template-driven and functional-styled language, getting them over the many differences between XSLT and the more conventional programming languages.Learning XSLT moves smoothly from the simple to complex, illustrating all aspects of XSLT 1.0 through step-by-step examples that you'll practice as you work through the book. Thorough in its coverage of the language, the book makes few assumptions about what you may already know. You'll learn about XSLT's template-based syntax, how XSLT templates work with each other, and gain an understanding of XSLT variables. Learning XSLT also explains how the XML Path Language (XPath) is used by XSLT and provides a glimpse of what the future holds for XSLT 2.0 and XPath 2.0.The ability to transform one XML vocabulary to another is fundamental to exploiting the power of XML. Learning XSLT is a carefully paced, example-rich introduction to XSLT that will have you understanding and using XSLT on your own in no time.

This impressive collection joins the recent outpouring of exciting new work on American politics and political actors in the mid-nineteenth century. For several generations, much of the scholarship on the political history of the period from 1840 to 1877 has carried a theme of failure; after all, politicians in the antebellum years failed to prevent war, and those of the Civil War and Reconstruction failed to take advantage of opportunities to remake the nation. Moving beyond these older debates, the essays in this volume ask new questions about mid-nineteenth-century American politics and politicians. In A Political Nation, the contributors address the dynamics of political parties and factions, illuminate the presence of consensus and conflict in American political life, and analyze elections, voters, and issues. In addition to examining the structures of the United States Congress, state and local governments, and other political organizations, this collection emphasizes political leaders--those who made policy, ran for office, influenced elections, and helped to shape American life from the early years of the Second Party System to the turbulent period of Reconstruction. The book moves chronologically, beginning with an antebellum focus on how political actors behaved within their cultural surroundings. The authors then use the critical role of language, rhetoric, and ideology in mid-nineteenth-century political culture as a lens through which to reevaluate the secession crisis. The collection closes with an examination of cultural and institutional influences on politicians in the Civil War and Reconstruction years. Stressing the role of federalism in understanding American political behavior, A Political Nation underscores the vitality of scholarship on mid-nineteenth-century American politics.
