Code Nation

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.

Over the long nineteenth century, African-descended peoples used the uncertainties and possibilities of emancipation to stake claims to freedom, equality, and citizenship. In the process, people of color transformed the contours of communities, nations, and the Atlantic World. Although emancipation was an Atlantic event, it has been studied most often in geographically isolated ways. The justification for such local investigations rests in the notion that imperial and national contexts are essential to understanding slaving regimes. Just as the experience of slavery differed throughout the Atlantic World, so too did the experience of emancipation, as enslaved people’s paths to freedom varied depending on time and place. With the essays in this volume, historians contend that emancipation was not something that simply happened to enslaved peoples but rather something in which they actively participated. By viewing local experiences through an Atlantic framework, the contributors reveal how emancipation was both a shared experience across national lines and one shaped by the particularities of a specific nation. Their examination uncovers, in detail, the various techniques employed by people of African descent across the Atlantic World, allowing a broader picture of their paths to freedom.
