It began life under the name ARPANet in 1969. It was born in the U.S.A., created in the midst of the Cold War by the government as a strategic mechanism that would provide for the emission and reception of electronic communication signals in the event of a world catastrophe. Commissioned by the Department of Defense, four computers called nodes were connected using modems, telephone wires and satellites, one each at UCLA, UCSB, Stanford and University of Utah. ARPANet stands for Advanced Research Projects Agency Network. Its purpose was to share information and results of research among the various scientists involved in Department of Defense projects. Each node was specifically designed io be independent of the others in case of that aforementioned world catastrophe.

Parallel prefix networks are used in priority encoders, and to compute carries in fast adders. A typical microprocessor contains many such networks, and often they are hot- spots. Although parallel prefix (or scan) has been much studied, surprisingly many questions remain unanswered. As geometries shrink, it is not at all clear how to make low power prefix networks with the desired timing properties. Here, I develop a method of writing very highly parameterised parallel prefix network generators in which we specify the combinators used to build the networks and then search for a topology that matches the given delay constraints. This first case study indicates that, in this functional setting, combinators and search fit well together. The resulting prefix networks are both small and shallow, and likely to be useful in low power applications.

The combination of evolving ICT standards that increase the interoperability between applications and the ever-increasing need for a more seamless access to and exchange of information is a major driver in the OECD ICT strategy. This paper describes the role and use of web services in the context of recent developments at the OECD to improve the accessibility of statistical information. It follows up on a paper presented at the 2002 ISIS meeting about “Improving Access to Statistical Information at OECD in Response to Users’ Requirements” and describes a technology framework – called “dot.STAT” – that has been devised for the implementation of applications that enable easy access to certain OECD reference data. The concepts outlined in this paper have been developed in close collaboration with the Statistics Directorate, specialised OECD-internal groups and task forces 2, as well as members of the SDMX Consortium3.

What Is Silverlight?
Silverlight is a new Web presentation technology that is created to run on a variety of platforms. It enables the creation of rich, visually stunning and interactive experiences that can run everywhere: within browsers and on multiple devices and desktop operating systems (such as the Apple Macintosh). In consistency with WPF (Windows Presentation Foundation), the presentation technology in Microsoft .NET Framework 3.0 (the Windows programming infrastructure), XAML (eXtensible Application Markup Language) is the foundation of the Silverlight presentation capability.

This book provides a set of design and implementation guidelines for writing secure programs for Linux and Unix systems. Such programs include application programs used as viewers of remote data, web applications (including CGI scripts), network servers, and setuid/setgid programs. Specific guidelines for C, C++, Java, Perl, Python, TCL, and Ada95 are included.

Large volumes of content (bookmarks, reviews, videos, etc.) are currently being created on the “Social Web”, i.e. on Web 2.0 community sites, and this content is being annotated and commented upon. The ability to view an individual’s entire contribution to the Social Web would be an interesting and valuable service, particularly important as social networks are often being formed through created content and things that people have in common (“object-centred sociality”). SIOC is a Semantic Web research project that aims to describe online communities on the Social Web. This paper describes how SIOC and the Semantic Web can enable linking and reuse scenarios of data from Web 2.0 community sites, and introduces a SIOC Types module to further specify the type of content items and act as a “glue” between user posts and the content items created and annotated by users.

This How To shows you how to create and configure a custom least-privileged service account to run an ASP.NET Web application. By default, an ASP.NET application on Microsoft Windows Server 2003 and IIS 6.0 runs using the built-in Network Service account. In production environments, you usually run your application using a custom service account. By using a custom service account, you can audit and authorize your application separately from others, and your application is protected from any changes made to the privileges or permissions associated with the Network Service account. To use a custom service account, you must configure the account by running the Aspnet_regiis.exe utility with the -ga switch, and then configure your application to run in a custom application pool that uses the custom account’s identity.
