Heartbeats

Heartbeat Art

An innovative history of heartbeats, pulse, and technoscience in the works of a wide international array of artists and composers. Heartbeat Art is the first study of how artists have engaged with heartbeats from the 1960s to the present, creating sophisticated and technological works that project in unique ways the circulatory processes of the body beyond its physical limits. Drawing on a long history of scientific and artistic experimentation, Claudia Arozqueta offers detailed case studies of heartbeat works by a wide range of international artists working at the interconnections of our bodies, art, and science and technology, including Yoko Ono, Pauline Oliveros, Heinz Mack, Brian O’Doherty, Teresa Burga, and many others. Technoscientific advances in monitoring heartbeats and pulses in the nineteenth century—such as René Laennec’s stethoscope, Étienne-Jules Marey’s sphygmograph and chronophotograph, and Willem Einthoven’s electrocardiograph—transformed the movements of the heart into audible and visual representations. Artists saw in the language of these scientific technologies a way of mingling the inner with the outer, the physical with the technological, and data with flesh. Using archival research, interviews, and correspondence, Arozqueta describes significant works in detail, discusses their contexts and development, and examines the larger classes and contours of this neglected area of artistic activity. Other artists in the volume include Éliane Radigue, Jean Dupuy, Linda Montano, Catherine Richards, Diana Domingues, Mona Hatoum, Rafael Lozano-Hemmer, and Christian Boltanski.

The Linux Enterprise Cluster

The Linux Enterprise Cluster explains how to take a number of inexpensive computers with limited resources, place them on a normal computer network, and install free software so that the computers act together like one powerful server. This makes it possible to build a very inexpensive and reliable business system for a small business or a large corporation. The book includes information on how to build a high-availability server pair using the Heartbeat package, how to use the Linux Virtual Server load balancing software, how to configure a reliable printing system in a Linux cluster environment, and how to build a job scheduling system in Linux with no single point of failure. The book also includes information on high availability techniques that can be used with or without a cluster, making it helpful for System Administrators even if they are not building a cluster. Anyone interested in deploying Linux in an environment where low cost computer reliability is important will find this book useful. The CD-ROM includes the Linux kernel, ldirectord software, the Mon monitoring package, the Ganglia package, OpenSSH, rsync, SystemImager, Heartbeat, and all the figures and illustrations used in the book.
