Pragmatic Version Control Using Subversion
What readers are saying about Pragmatic Version Control using Subversion I expected a lot, but you surprised me with even more. Hav- ing used CVS for years I hesitated to try Subversion until now, although I knew it would solve many of the shortcom- ings of CVS. After reading your book, my excuses to stay with CVS disappeared. Oh, and coming from the Pragmatic Bookshelf this book is fun to read too. Thanks Mike. Steffen Gemkow Managing Director, ObjectFab GmbH I’m a long-time user of CVS and I’ve been skeptical of Sub- version, wondering if it would ever be “ready for prime time.” Until now. Thanks to Mike Mason for writing a clear, con- cise, gentle introduction to this new tool. After reading this book, I’m actually excited about the possibilities for version control that Subversion brings to the table. David Rupp Senior Software Engineer, Great-West Life & Annuity This was exactly the Subversion book I was waiting for. As a long-time Perforce and CVS user and administrator, and in my role as an agile tools coach, I wanted a compact book that told me just what I needed to know. This is it. Within a couple of hours I was up and running against remote Subversion servers, and setting up my own local servers too. Mike uses a lot of command-line examples to guide the reader, and as a Windows user I was worried at first. My fears were unfounded though—Mike’s examples were so clear that I think I’ll stick to using the command line from now on! I thoroughly recommend this book to anyone getting started using or administering Subversion. -

TRABAJO DE FIN DE CARRERA TÍTULO DEL TFC: VirtualEPSC, el mundo virtual 2.0 del Campus del Baix Llobregat TITULACIÓN: Ingeniería Técnica de Telecomunicación, especialidad en Telemática AUTORES: Luis Miguel Amorós Martínez Noemí Arbós Linio DIRECTOR: Toni Oller Arcas FECHA: 14 de julio de 2010 Título: VirtualEPSC, el mundo virtual 2.0 del Campus del Baix Llobregat Autores: Luis Miguel Amorós Martínez Noemí Arbós Linio Director: Toni Oller Arcas Fecha: 14 de julio de 2010 Resumen En las últimas décadas, se han producido cambios tecnológicos de gran envergadura que han provocado una ruptura brusca con las tecnologías existentes hasta el momento. Una de las más importantes es Internet, que se ha convertido en el entorno de comunicación más importante de la historia, con más de mil millones de usuarios en todo el mundo. Internet ha sufrido una serie de cambios en los últimos años y uno de los últimos conceptos que han surgido es el de web 2.0. Esta filosofía se basa en dar un rol más activo a los usuarios, por ejemplo, utilizando la colaboración de los usuarios en Internet, también llamado inteligencia colectiva; y en el diseño centrado en el usuario. Este trabajo describe los pasos seguidos para desarrollar una web 2.0 que aloja un mundo virtual que emula el Campus del Baix Llobregat. Se describe cómo son el diseño y la arquitectura del proyecto, y cómo se ha hecho la implementación de las diferentes partes. El resultado se denomina VirtualEPSC, una web 2.0 que aloja una aplicación multimedia en 2D que emula el Campus del Baix Llobregat, donde los usuarios podrán interactuar entre ellos. -

Tracking Known Security Vulnerabilities in Third-Party Components

All rights reserved. Tracking known security vulnerabilities in third-party components Author: Mircea Cadariu Student id: 4252373 Email: [email protected] Abstract Known security vulnerabilities are introduced in software systems as a result of de- pending on third-party components. These documented software weaknesses are hiding in plain sight and represent the lowest hanging fruit for attackers. Despite the risk they introduce for software systems, it has been shown that developers consistently download vulnerable components from public repositories. We show that these downloads indeed find their way in many industrial and open-source software systems. In order to improve the status quo, we introduce the Vulnerability Alert Service, a tool-based process to track known vulnerabilities in software projects throughout the development process. Its usefulness has been empirically validated in the context of the external software product quality monitoring service offered by the Software Improvement Group, a software consultancy company based in Amsterdam, the Netherlands.

Exploring Factors and Measures to Select Open Source Software
Exploring Factors and Measures to Select Open Source Software Xiaozhou Li*a, Sergio Moreschini*a, Zheying Zhanga, Davide Taibia aTampere University, Tampere (Finland) ∗ the two authors equally contributed to the paper Abstract [Context] Open Source Software (OSS) is nowadays used and integrated in most of the commercial products. However, the selection of OSS projects for integration is not a simple process, mainly due to a of lack of clear selection models and lack of information from the OSS portals. [Objective] We investigated the current factors and measures that prac- titioners are currently considering when selecting OSS, the source of infor- mation and portals that can be used to assess the factors, and the possibility to automatically get this information with APIs. [Method] We elicited the factors and the measures adopted to assess and compare OSS performing a survey among 23 experienced developers who often integrate OSS in the software they develop. Moreover, we investigated the APIs of the portals adopted to assess OSS extracting information for the most starred 100K projects in GitHub. [Result] We identified a set consisting of 8 main factors and 74 sub- factors, together with 170 related metrics that companies can use to select OSS to be integrated in their software projects. Unexpectedly, only a small part of the factors can be evaluated automatically, and out of 170 metrics, only 40 are available, of which only 22 returned information for all the 100K projects. [Conclusion.] OSS selection can be partially automated, by extracting arXiv:2102.09977v1 [cs.SE] 19 Feb 2021 the information needed for the selection from portal APIs.
