This 25th anniversary edition of Steven Levy's classic book traces the exploits of the computer revolution's original hackers -- those brilliant and eccentric nerds from the late 1950s through the early '80s who took risks, bent the rules, and pushed the world in a radical new direction. With updated material from noteworthy hackers such as Bill Gates, Mark Zuckerberg, Richard Stallman, and Steve Wozniak, Hackers is a fascinating story that begins in early computer research labs and leads to the first home computers. Levy profiles the imaginative brainiacs who found clever and unorthodox solutions to computer engineering problems. They had a shared sense of values, known as "the hacker ethic," that still thrives today. Hackers captures a seminal period in recent history when underground activities blazed a trail for today's digital world, from MIT students finagling access to clunky computer-card machines to the DIY culture that spawned the Altair and the Apple II.

Designed to appeal to lay readers and specialists alike, this concise, scientific analysis refutes the pessimistic global warming scenarios depicted in the media. In addition to covering better-known topics such as the climate record, computer models, and the effects of clouds, oceans, and greenhouse gases, the book also provides an in-depth examination of less frequently discussed issues including the inaccuracies in historical climate data, the limitations of attempting to model climate on computers, solar variability and its impact on climate, and factors that could mitigate any human impacts on world climate. Potential upsides related to global warming and the extreme financial consequences that economically disadvantaged groups and nations would suffer as a result of many of the proposed solutions are identified.

Nearly a decade ago, Johanna Drucker cofounded the University of Virginia’s SpecLab, a digital humanities laboratory dedicated to risky projects with serious aims. In SpecLab she explores the implications of these radical efforts to use critical practices and aesthetic principles against the authority of technology based on analytic models of knowledge. Inspired by the imaginative frontiers of graphic arts and experimental literature and the technical possibilities of computation and information management, the projects Drucker engages range from Subjective Meteorology to Artists’ Books Online to the as yet unrealized ’Patacritical Demon, an interactive tool for exposing the structures that underlie our interpretations of text. Illuminating the kind of future such experiments could enable, SpecLab functions as more than a set of case studies at the intersection of computers and humanistic inquiry. It also exemplifies Drucker’s contention that humanists must play a role in designing models of knowledge for the digital age—models that will determine how our culture will function in years to come.
