  • Users As Co-Designers of Software-Based Media: the Co-Construction of Internet Relay Chat
    Users as Co-Designers of Software-Based Media: The Co-Construction of Internet Relay Chat Guillaume Latzko-Toth Université Laval AbsTrAcT While it has become commonplace to present users as co-creators or “produsers” of digital media, their participation is generally considered in terms of content production. The case of Internet Relay Chat (IRC) shows that users can be fully involved in the design process, a co-construction in the sense of Science and Technology Studies (STS): a collective, simultaneous, and mutual construction of actors and artifacts. A case study of the early de - velopment of two IRC networks sheds light on that process and shows that “ordinary users” managed to invite themselves as co-designers of the socio-technical device. The article con - cludes by suggesting that IRC openness to user agency is not an intrinsic property of software- based media and has more to do with its architecture and governance structure. Keywords Digital media; Communication technology; Co-construction; Design process; Ordinary user résumé Il est devenu banal de présenter l’usager comme cocréateur ou « produtilisateur » des médias numériques, mais sa participation est généralement envisagée comme une production de contenus. Le cas d’IRC (Internet Relay Chat) montre que les usagers des médias à support logiciel peuvent s’engager pleinement dans le processus de conception, une co-construction au sens des Science and Technology Studies : une construction collective, simultanée et mutuelle des acteurs et des artefacts. Une étude de cas portant sur le développement de deux réseaux IRC éclaire ce processus et montre que les « usagers ordinaires » sont parvenus à s’inviter comme co-concepteurs du dispositif.

  • Instalación Y Administración De Servicios De Mensajería Instantánea, Noticias Y Listas De Distribución
    Servicios de red e internet Instalación y administración de servicios de mensajería instantánea, noticias y listas de distribución Raquel Castellanos Crespo Instalación y administración de servicios de mensajería instantánea, noticias y listas de distribución Servicios de red e internet Raquel Castellanos Crespo INDICE 2 Servicios de red e internet | Instalación y administración de servicios de mensajería instantánea, noticias y listas de distribución Servicios de red e internet Raquel Castellanos Crespo Protocolos La mensajería instantánea (conocida también en inglés como IM) es una forma de comunicación en tiempo real entre dos o más personas basada en texto. El texto es enviado a través de dispositivos conectados a una red como Internet. La mensajería instantánea requiere el uso de un cliente de mensajería instantánea que realiza el servicio y se diferencia del correo electrónico en que las conversaciones se realizan en tiempo real. La mayoría de los servicios ofrecen el "aviso de presencia", indicando cuando el cliente de una persona en la lista de contactos se conecta o en qué estado se encuentra, si está disponible para tener una conversación. En los primeros programas de mensajería instantánea, cada letra era enviada según se escribía y así, las correcciones de las erratas también se veían en tiempo real. Esto daba a las conversaciones más la sensación de una conversación telefónica que un intercambio de texto. En los programas actuales, habitualmente, se envía cada frase de texto al terminarse de escribir. Además, en algunos, también se permite dejar mensajes aunque la otra parte no esté conectada al estilo de un contestador automático. Otra función que tienen muchos servicios es el envío de ficheros.

    Introduction To Online Sexual Exploitation: Curriculum February 2003 Safe OnLine Outreach Project © M. Horton 2003 Safe OnLine Outreach Project Acknowledgements This document is the result of many hours of hard work and dedication. I'd like to thank Renata Karrys, Jaynne Aster, Nikki O'Halloran, Charlaine Avery, Lisa Ingvallsen and Elizabeth Nethery for their support and assistance in producing this document. Additionally the SOLO Advisory Committee, the Canadian National Crime Prevention - Community Mobilization Program, the Vancouver Foundation, Athabasca University/MediaCan and Parents Against Sexual Abuse have all been instrumental in turning this idea into a Project. Lastly, David and Conor have been silent contributors to this project since it began. Their support is woven into each page. Merlyn Horton SOLO Project Coordinator February 2003 Safe OnLine Outreach Project February 3, 2003 Introduction to the Curriculum Dear Reader, The curriculum you hold in your hands was produced in a former pottery studio in the middle of a coastal rain forest in British Columbia, Canada; the physical launch pad for this examination of a virtual issue. It is the result of three years of research. This introduction is intended to outline a context for the curriculum and to give you an overview of how to use this curriculum, who should present this curriculum and how appropriate audiences might be chosen. Context The philosophical foundation for this curriculum, and indeed for the Safe OnLine Outreach Project, is the United Nations Convention on the Rights of the Child (CRC)1. The CRC is one of four Conventions created by the United Nations to further the goal of recognizing the inherent dignity and rights of all members of the human family2.

  • Botnets, Zombies, and Irc Security
    Botnets 1 BOTNETS, ZOMBIES, AND IRC SECURITY Investigating Botnets, Zombies, and IRC Security Seth Thigpen East Carolina University Botnets 2 Abstract The Internet has many aspects that make it ideal for communication and commerce. It makes selling products and services possible without the need for the consumer to set foot outside his door. It allows people from opposite ends of the earth to collaborate on research, product development, and casual conversation. Internet relay chat (IRC) has made it possible for ordinary people to meet and exchange ideas. It also, however, continues to aid in the spread of malicious activity through botnets, zombies, and Trojans. Hackers have used IRC to engage in identity theft, sending spam, and controlling compromised computers. Through the use of carefully engineered scripts and programs, hackers can use IRC as a centralized location to launch DDoS attacks and infect computers with robots to effectively take advantage of unsuspecting targets. Hackers are using zombie armies for their personal gain. One can even purchase these armies via the Internet black market. Thwarting these attacks and promoting security awareness begins with understanding exactly what botnets and zombies are and how to tighten security in IRC clients. Botnets 3 Investigating Botnets, Zombies, and IRC Security Introduction The Internet has become a vast, complex conduit of information exchange. Many different tools exist that enable Internet users to communicate effectively and efficiently. Some of these tools have been developed in such a way that allows hackers with malicious intent to take advantage of other Internet users. Hackers have continued to create tools to aid them in their endeavors.

Back then, online to the average user meant a telephone connection directly to either another computer or to an online service, such as CompuServe or AOL. The Internet now dominates all online activity. In popular parlance, the Internet is synonymous with the World Wide Web, although it is much more, as we’ll explain in this book. The Internet can be described generally as a “network” of networks. It is a transportation vehicle for applications. In fact, the visual representations of the Net look like a road map. If lines are drawn between each connection, between larger and larger connections, and between smaller and smaller ones, the end result is a web of connections—a virtual road map. This book is divided into four rough sections. The first is for beginners. It is to get anyone up to speed quickly with the information needed about the Web. Each chapter has recommended Web sites (to type the address, or Uniform Resource Locator [URL] into your Web browser) to help direct you. The second section has more detailed information about downloads, email, secu- rity, and information on virus protection. The third part is about how to create a Web site, Web tools, blogging, and what you can add to your Web site (such as streaming media, RSS feeds, and XML, among other things). The fourth part is by far the densest.
