  • 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.

  • Evaluation of the CSF Firewall
    Bachelor Thesis in Software Engineering, 15 credits May 2013 Evaluation of the CSF Firewall Ahmad Mudhar Contact Information: Ahmad Mudhar E-mail: [email protected] University advisor: Kari Rönkkö Nina Fogelström School of Computing Internet : www.bth.se/com Blekinge Institute of Technology Phone : +46 455 38 50 00 SE-371 79 Karlskrona Fax : +46 455 38 50 57 Sweden 1 Abstract The subject of web server security is vast, and it is becoming bigger as time passes by. Every year, researches, both private and public, are adding to the number of possible threats to the security of web servers, and coming up with possible solutions to them. A number of these solutions are considered to be expensive, complex, and incredibly time-consuming, while not able to create the perfect web to challenge any breach to the server security. In the study that follows, an attempt will be made to check whether a particular firewall can ensure a strong security measure and deal with some security breaches or severe threat to an existing web server. The research conducted has been done with the CSF Firewall, which provides a suit of scripts that ensure a portal’s security through a number of channels. The experiments conducted under the research provided extremely valuable insights about the application in hand, and the number of ways the CSF Firewall can help in safety of a portal against Secured Shell (SSH) attacks, dedicated to break the security of it, in its initial stages. It further goes to show how simple it is to actually detect the prospective attacks, and subsequently stop the Denial of Service (DoS) attacks, as well as the port scans made to the server, with the intent of breaching the security, by finding out an open port.

  • Trabajo De Fin De Carrera
    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.
