Culture and Code: The Evolution of Digital Architecture and the Formation of Networked Publics

Culture and Code traces the construction of the modern idea of the Internet and offers a potential glimpse of how that idea may change in the near future. Developed through a theoretical framework that links Sheila Jasanoff and Sang-Hyun Kim’s theory of the sociotechnical imaginary to broader theories on publics and counterpublics, Culture and Code offers a way to reframe the evolution of Internet technology and its culture as an enmeshed part of larger socio-political shifts within society. In traveling the history of the modern Internet as detailed in its technical documentation, legal documents, user created content, and popular media this dissertation positions the construction of the idea of the Internet and its technology as the result of an ongoing series of intersections and collisions between the sociotechnical imaginaries of three different publics: Implementors, Vendors, and Users. These publics were identified as the primary audiences of the 1989 Internet Engineering Task Force specification of the four-layer TCP/IP model that became a core part of our modern infrastructure. Using that model as a continued metaphor throughout the work, Culture and Code shows how each public’s sociotechnical imaginary developed, how they influenced and shaped one another, and the inevitable conflicts that arose leading to a coalescing sociotechnical imaginary that is centered around vendor control while continuing to project the ideal of the empowered user

Future of the Internet--and how to stop it

vi, 342 p. : ill. ; 25 cmLibro ElectrónicoOn January 9, 2007, Steve Jobs introduced the iPhone to an eager audience crammed into San Francisco’s Moscone Center.1 A beautiful and brilliantly engineered device, the iPhone blended three products into one: an iPod, with the highest-quality screen Apple had ever produced; a phone, with cleverly integrated functionality, such as voicemail that came wrapped as separately accessible messages; and a device to access the Internet, with a smart and elegant browser, and with built-in map, weather, stock, and e-mail capabilities. It was a technical and design triumph for Jobs, bringing the company into a market with an extraordinary potential for growth, and pushing the industry to a new level of competition in ways to connect us to each other and to the Web.Includes bibliographical references (p. 249-328) and index Acceso restringido a miembros del Consorcio de Bibliotecas Universitarias de Andalucía Electronic reproduction.

Greenpass Client Tools for Delegated Authorization in Wireless Networks

Dartmouth\u27s Greenpass project seeks to provide strong access control to a wireless network while simultaneously providing flexible guest access; to do so, it augments the Wi-Fi Alliance\u27s existing WPA standard, which offers sufficiently strong user authentication and access control, with authorization based on SPKI certificates. SPKI allows certain local users to delegate network access to guests by issuing certificates that state, in essence, he should get access because I said it\u27s okay. The Greenpass RADIUS server described in Kim\u27s thesis [55] performs an authorization check based on such statements so that guests can obtain network access without requiring a busy network administrator to set up new accounts in a centralized database. To our knowledge, Greenpass is the first working delegation-based solution to Wi-Fi access control. My thesis describes the Greenpass client tools, which allow a guest to introduce himself to a delegator and allow the delegator to issue a new SPKI certificate to the guest. The guest does not need custom client software to introduce himself or to connect to the Wi-Fi network. The guest and delegator communicate using a set of Web applications. The guest obtains a temporary key pair and X.509 certificate if needed, then sends his public key value to a Web server we provide. The delegator looks up her guest\u27s public key and runs a Java applet that lets her verify her guests\u27 identity using visual hashing and issue a new SPKI certificate to him. The guest\u27s new certificate chain is stored as an HTTP cookie to enable him to push it to an authorization server at a later time. I also describe how Greenpass can be extended to control access to a virtual private network (VPN) and suggest several interesting future research and development directions that could build on this work.My thesis describes the Greenpass client tools, which allow a guest to introduce himself to a delegator and allow the delegator to issue a new SPKI certificate to the guest.

How to accelerate your internet : a practical guide to bandwidth management and optimisation using open source software

xiii, 298 p. : ill. ; 24 cm.Libro ElectrónicoAccess to sufficient Internet bandwidth enables worldwide electronic collaboration, access to informational resources, rapid and effective communication, and grants membership to a global community. Therefore, bandwidth is probably the single most critical resource at the disposal of a modern organisation. The goal of this book is to provide practical information on how to gain the largest possible benefit from your connection to the Internet. By applying the monitoring and optimisation techniques discussed here, the effectiveness of your network can be significantly improved

Interoperability of DRM Systems

The study deals with the cutting-edge subject of electronic contracts which have the potential to automatically process and control the access rights for (electronic) goods. It shows the design and the implementation of a rights expression exchange framework. The framework allows DRM systems to exchange electronic contracts, formulated in a standardized rights expression language, and thus provides DRM system interoperability. The work introduces a methodology for the standardized composition, exchange and processing of electronic contracts or rights expressions

The Future of the Internet and How to Stop It

This extraordinary book explains the engine that has catapulted the Internet from backwater to ubiquity—and reveals that it is sputtering precisely because of its runaway success. With the unwitting help of its users, the generative Internet is on a path to a lockdown, ending its cycle of innovation—and facilitating unsettling new kinds of control. IPods, iPhones, Xboxes, and TiVos represent the first wave of Internet-centered products that can’t be easily modified by anyone except their vendors or selected partners. These “tethered appliances” have already been used in remarkable but little-known ways: car GPS systems have been reconfigured at the demand of law enforcement to eavesdrop on the occupants at all times, and digital video recorders have been ordered to self-destruct thanks to a lawsuit against the manufacturer thousands of miles away. New Web 2.0 platforms like Google mash-ups and Facebook are rightly touted—but their applications can be similarly monitored and eliminated from a central source. As tethered appliances and applications eclipse the PC, the very nature of the Internet—its “generativity,” or innovative character—is at risk. The Internet’s current trajectory is one of lost opportunity. Its salvation, Zittrain argues, lies in the hands of its millions of users. Drawing on generative technologies like Wikipedia that have so far survived their own successes, this book shows how to develop new technologies and social structures that allow users to work creatively and collaboratively, participate in solutions, and become true “netizens.” The author has made an online version of this work available under a Creative Commons Attribution-Noncommercial-Share Alike 3.0 License.
