DSpace How-To Guide: Tips and tricks for managing common DSpace chores

PDF fileThis short booklet is intended to introduce the commonest non-obvious customization related tasks for newcomers to DSpace administration. It has been written against the current stable version 1.3.2 of DSpace. We have tried to include instructions for different operating systems as required; most customizations, however, work identically cross-platform

FORM Matters: Fast Symbolic Computation under UNIX

We give a brief introduction to FORM, a symbolic programming language for massive batch operations, designed by J.A.M. Vermaseren. In particular, we stress various methods to efficiently use FORM under the UNIX operating system. Several scripts and examples are given, and suggestions on how to use the vim editor as development platform.Comment: 10 pages, PDF document (PDFLaTeX source available upon request) with 2 JPG figures; submitted to Computers & Mathematics with Application

Deliverable DJRA1.3: Tool prototype for creating and stitching multiple network resources for virtual infrastructures

This document describes the prototype FEDERICA Slice Tool developed for the virtualization of network elements in FEDERICA and for creating and stitching network resources over this virtual infrastructure. An SNMP-based resource discovery prototype is also introduced as a new functionality to be integrated in the tool.The deliverable also presents aviability study for the use of traffic prioritization in the FEDERICA infrastructure and some network performance measurements on a real slice within FEDERICA.This document reports the final results of JRA1.2 Activity in the development of a tool prototype for creating sets ofvirtual resourcesinFEDERICA.The prototype goal is to simplify and automate part of the work for NOC.The tool may also serve,with different privileges, a FEDERICA user to operate on his/her slice. The tool described here was designed with the objective of providing an interactive application with a graphical interface to operate on resources for the NOC and the end users (researchers). The tool simplify the creation and configuration of resources in a slice and it is a mandatory step to ensure scalability of the NOC effort. It offers an interactive Graphical User Interface that translates the users’ actions to commands in the substrate (networknodesandV-nodes)andslice elements(VirtualMachines).User accounts may be created for the NOC and for researchers, each with specific privileges to enable different sets of capabilities. The NOC account has full access to all the resources in the substrate, while each user’account has full access only to the virtual resources in his/her slice. The tool has been developed using the Java programming language as Open Source code and relies on the open source Globus® Toolkit. Testing has been performed in a laboratory environment and on some FEDERICA substrate equipment (1switch, 2VMwareServers) in their standard configuration. For testing the router, web services and GUI an additional computer was used, using a public IP address.Postprint (published version

Linux Networking Cookbook is a soup-to-nuts collection of recipes that covers everything you need to know to perform your job as a Linux network administrator. You'll dive straight into the gnarly hands-on work of building and maintaining a computer networ

Telemedicine system in the South Atlantic. Phase VII (I)

The information technology and communications (also known as ICT) are an essential part of the evolution in the economy and society. Access to information has become a vital tool for the development of a community. Consequently, there has been a phenomenon known as "digital divide", which refers to differences between countries that have access to ICT and those without. This project aims to provide a small gesture to reduce the gap between what is often called "differences between North and South", providing an improvement in the telemedicine system that the NGO Telecos Sense Fronteres is developing to the Region of South Atlantic of Nicaragua since 2006. This seventh stage of the project has tried, first of all, to make a careful maintenance of the infrastructure and equipment which currently has the Hospital Ernesto Sequeira Blanco of Bluefields; to improve their performance by incorporating a system of virtual desktops. In addition, the VoIP telephony system has been expanded to other departments of the hospital and other health centres of Bluefields, plus designing a virtual private network for their internal use. Secondly, there has been worked in a radio-link to bring telemedicine to Monkey Point, a rural community, isolated and without access to telecommunications. Finally, it has been emphasized the fact to bring the project to the community of Bluefields in order that they appropriate it and not see it as mere spectators. Related to this, some collaboration agreements have been closed with various local institutions that can contribute to self-management of the project, such as Bluefields Indian & Caribbean University (with engineering students) or the Sistema Local de Atención Integral en Salud (both with the economic and health sides).Català: Les tecnologies de la informació i les comunicacions (també anomenades TIC) són una part essencial dels canvis en l'economia i la societat actual. L'accés a la informació s'ha convertit en una eina vital pel desenvolupament d'una comunitat. Arran d'això, ha sorgit un fenomen conegut com a “bretxa digital”, el qual fa referència a les diferències entre països que tenen accés a les TIC, i aquells que no. Aquest projecte pretén aportar un petit gest per tal de disminuir aquesta bretxa entre el que freqüentment s'anomena “diferències entre Nord i Sud”, proporcionant una millora en el Sistema de Telemedicina que la ONG Telecos Sense Fronteres està desenvolupant a la Regió de l'Atlàntic Sur de Nicaragua des del 2006. En aquesta setena fase del projecte, s'ha pretés, en primer lloc, fer un manteniment acurat de la infraestructura i els equips dels quals disposa l'Hospital Ernesto Sequeira Blanco de Bluefields, millorat-ne les prestacions amb la incorporació d'un sistema d'escriptoris virtuals. A més, s'ha ampliat la xarxa de telefonia VoIP per tal de fer-la extensiva a altres departaments de l'hospital i a altres centres de salut de la població, concretant una xarxa privada virtual pel seu ús intern. En segon terme, s'ha treballat en un radioenllaç per fer arribar la telemedicina a Monkey Point, una comunitat rural, aïllada i sense accés a les telecomunicacions. Finalment, s'ha fet èmfasi en apropar el projecte a la pròpia comunitat de Bluefields amb la finalitat que se l'apropiïn i no el vegin com a mers espectadors. En aquesta direcció, s'han establert convenis de col·laboració amb diferents entitats que poden contribuir a l'autogestió del projecte, com són la Bluefields Indian & Caribbean University (amb estudiants d'enginyeria) o el Sistema Local de Atención Integral en Salud (amb la part econòmica i relacionada amb la salut)
