The needs of future digital data and computer systems are expected to be two to three orders of magnitude larger than for today's systems, to take account of unprecedented amounts of heterogeneous hardware, lines of source code, numbers of users, and volumes of data. Ultrascale computing systems (UCS) are a solution. Envisioned as large-scale complex systems joining parallel and distributed computing systems, which can be located at multiple sites and cooperate to provide the required resources and performance to the users, these technologies will extend individual systems to provide the resources that are very much needed.

Up until a few years ago there were many different modelling languages available to software developers. However, this vast array of choice only served to hinder communication and as a result the Unified Modelling Language (UML) was born. Although the UML has its roots firmly in the software world, the benefits of adopting a standard visual notation have been recognised in many other fields, not least of which is the field of systems engineering. This book concentrates on systems-based applications, rather than the traditional software applications that are more usually associated with the UML. Now fully updated to reflect the changes to UML for its version 2.0 release, this new edition has been substantially re-written and includes new material on systems architectures and life cycle management.

How social media videos shape today’s political engagement and activism.

What political power do social media videos have? In what ways do they exert influence, shape public discourse, and change political life? How can participants in this field assert themselves against commercial interests, anti-democratic agitation, and authoritarian propaganda? These questions are being debated intensely as social media increasingly dominates global information flows, and videos increasingly dominate social media.

The forms, practices, and opportunities of activism depend on a media environment that is changing rapidly and profoundly in terms of its technological basis, ownership, legal regulations, and governmental control. This makes the act of understanding video activism even more relevant at a time when the internet is undergoing fundamental disruptions.
 

Unmanning studies the conditions that create unmanned platforms in the United States through a genealogy of experimental, pilotless planes flown between 1936 and 1992. Characteristics often attributed to the drone—including machine-like control, enmity and remoteness—are achieved by displacements between humans and machines that shape a mediated theater of war. Rather than primarily treating the drone as a result of the war on terror, this book examines contemporary targeted killing through a series of failed experiments to develop unmanned flight in the twentieth century. The human, machine and media parts of drone aircraft are organized to make an ostensibly not human framework for war that disavows its political underpinnings as technological advance. These experiments are tied to histories of global control, cybernetics, racism and colonialism. Drone crashes and failures call attention to the significance of human action in making technopolitics that comes to be opposed to “man” and the paradoxes at their basis.
 

How users experience and influence technological change—when so much of that change feels out of our control

Every day, we casually employ one of the most complex tools ever created, using it to read the news, plan our day, and connect with friends. In A User’s Guide to the Age of Tech, Grant Wythoff investigates the process by which now-ubiquitous technologies like our phones become integrated into our lives, showing how the “gadget” stage—before devices are widely adopted—opens the door for users to co-create these technologies and adapt them toward unexpected ends. 

In this elegant, approachable work, Wythoff offers a view of how users make new technology their own, subverting dominant power structures and imagining uses never intended by their creators. Rooted in a detailed look into the history of technique (focusing on how we do things with tools rather than the tools themselves), A User’s Guide to the Age of Tech proceeds to complicate, and influence, discussion of subjects like the digital divide and AI.

Drawing on a range of sources, including novels, patents, and newspapers, Wythoff explores the vernacular philosophies that have emerged from users and their diverse, everyday practices, bringing down to earth the conversation about digital titans, away from the abstracted domains of server farms and algorithms. Lodging a passionate argument that we know ourselves better than the data brokers who appear to wield influence over our psyches, Wythoff invites readers (and tech users) to imagine their own digital technique, acknowledge their vast expertise, and see its immense value.
