3D printers are a type of digital fabrication tool being used by communities committed to shared software, hardware, and digital designs. This shared digital knowledge can be understood as an emerging common resource for the fabrication of physical goods and services. Yet the knowledge associated with physical resources used in 3D printing is less understood. This thesis explores what factors enable or prevent knowledge about physical materials entering the commons. 3D printing, with its particular configuration of digital and physical goods, offers a unique angle to advance the field of commons scholarship. This thesis elaborates the use of commons theory for traversing the boundary between knowledge associated with physical materials and digital content from the perspective of 3D printer users. Particular contributions are made to the branch of knowledge commons theory: notably, how design rules in technological systems can be used to theorise boundaries; how differentiating between the nature of underlying resources can help explain the inclusion of knowledge in the commons; and, how patterns of user engagement with types of knowledge in the commons can be studied over time. To develop these contributions I employ theory on the design rules of technological architecture, and use insights from the study of peer production in online communities. Empirical data comes from a qualitative study of users of Fab Labs, community workshops for digital fabrication, as well as from a quantitative study of the online user forum for the Ultimaker 3D printer.

The diploma thesis deals with the analysis, development and implementation of software using Qt framework. It reflects the history of the parents´ association and its need to register pupils attending a primary school, respectively members of the association. The diploma thesis goes through the various phases of design and development software using the Open Unified Process methodology and its subsequent processing using UML. The outputs from the analytical and design parts are then used to implement a custom registration system. This paper describes and compares several methods currently used in software development and introduces the reader to the basic principles of object-oriented programming. It provides an overview of the components and principles of processing framework Qt 5, the SDK development environment and the consequences resulting through practical uses when developing applications.

Nesta dissertação são descritas as diferentes práticas culturais que compõem a comunidade brasileira de Software Livre e de Código Aberto com o objetivo de demonstrar como são criados os laços entre agentes para a constituição de redes. Com base no trabalho de dois anos e meio de pesquisa, assumimos o ângulo das práticas culturais e do reconhecimento de agentes para problematizar a oposição binária que domina grande parte do debate sobre altruísmo e interesse próprio em economias da dádiva. Ao centrarmos o foco nas redes de trabalho e prestígio, procuramos demonstrar quão heterogênea é a malha de redes da comunidade F/LOSS brasileira. As orientações teóricas e metodológicas da antropologia do dom de Caillé e da antropologia da tecnologia de Ingold e Pfaffenberger foram combinadas para a investigação da conformação da comunidade brasileira em três domínios experienciais: o técnico, o político e o cultural. O trabalho de pesquisa foi conduzido nos encontros nacionais da comunidade brasileira, bem como através das listas de discussão, wikis, blogs, portais de notícias e conversas informais na rede IRC Freenode. O desenvolvimento da pesquisa aponta para o surgimento de uma nova cultura tecnopolítica no Brasil, produto de práticas políticas e técnicas intimamente relacionadas ao Software Livre e de Código Aberto. / In this thesis, I turn to various agents in the Brazilian Free and Open Software community - developers, evangelists, politicians, and users - in order to discuss how gift economy works to shape commitments among them for the building of networks. Drawing on two and a half years of research, I take the angle of cultural practices and prestige to problematize the binary opposition between altruism and self-interest that dominates much of the literature. By focusing on social networks and the production of prestige, I am able to demonstrate how heterogeneous the composition of social networks are for the Brazilian economy of F/LOSS sharing. The theoretical and methodological orientation of Caillé's "Anthropologie du Don" and Pfaffenberger's and Ingold's "Anthropology of Technology" were combined to describe the community of Brazilian agents, engaged in three experiential domains: technical (producers), political (agents that promote F/OSS in the federal government), and cultural (artists whose work is empowered by F/OSS and the concept of Free Culture). The research work was conducted during the gatherings of F/OSS community in Brazil, as well as in electronic mailing lists, wikis, Internet sites and informal discussions via IRC. The development of the research points to the emergence of a new technical and political culture in Brazil, embodied by the "free software movement" therefore articulating political, cultural and technological practices.

Da relação simbiótica entre a sociedade informacional e pós-moderna, a cultura e as novas tecnologias de informação e comunicação emerge uma nova forma sócio-cultural denominada Cibercultura Nesse contexto, com base em experiências bem sucedidas das comunidades desenvolvimento de software livre, assistimos o surgimento de diversas iniciativas no ciberespaço com o objetivo de colaborar em torno da produção de bens culturais e informacionais de interesse comum. Os projetos de software livre e outras iniciativas surgidas no ciberespaço são exemplos da emergência de uma nova forma de produção em rede baseada em colaboração em larga escala movida por indivíduos auto-motivados. Esta pesquisa visa investigar de que forma essa produção colaborativa ocorre na comunidade de desenvolvimento do projeto GNOME. O GNOME é um projeto de software livre que visa desenvolver um ambiente desktop para GNU/ Linux e outros sistemas similares ao Unix, e uma plataforma de desenvolvimento para a criação de novos aplicativos para o desktop. O projeto GNOME possui uma comunidade de aproximadamente 500 contribuidores de diversas nacionalidades que colaboram através da Internet no desenvolvimento de módulos de softwares de alta complexidade. Mais especificamente, buscaremos realizar um estudo sobre a relação entre tecnologias de comunicação e ações coletivas e colaborativas no ciberespaço; identificar quais instrumentos de comunicação eletrônica são utilizados no GNOME e como estes instrumentos são utilizados na colaboração entre os seus participantes. / Salvador

Open source products such as software development tools and server applications are gaining popularity among expert users. There is however a notable lag in adoption of desktop open source software among ordinary users especially in Africa. A number of critical factors such as performance expectancy, effort expectancy and facilitating conditions have been suggested as the determinants of Information and Communication Technologies adoption in general. This study deemed it important to establish if the above factors are the determinants of desktop open source software adoption in Africa. The study aimed to establish the Open Source Software adoption levels among university students in Kenya as well as the factors affecting Open Source Software adoption in this population. The author further aimed to assess the applicability of popular technology acceptance models in the adoption of the software in the population under study. The study employed literature review, quantitative and qualitative approaches. The study also used both descriptive and explanatory research designs in answering the research questions. The Extended Unified Theory of Acceptance and Use of Technology was used as a theoretical framework because it has synthesised all its major predecessors and accommodated all the predecessors constructs. The other reason The Extended Unified Theory of Acceptance and Use of Technology was used is because the model was developed specifically for predicting voluntary technology adoption. This study established that the adoption of Free Open Source Software products in Kenya is very low and existing literature revealed that this is also the case in other developing countries. The study concluded that the factors affecting adoption of desktop Open Source Software by Kenyan university students are usability, user training, Open Source Software compatibility, social influence, prior experience, social economic status, job market demands, proprietary software piracy culture and patent and copyright laws. Hence the study suggested that the existing technology adoption models are not appropriate in predicting technology adoption in an Africa setup. The study proposed and validated an appropriate model that fits in this context. / School of Computing / D.Phil. (Information Systems)

Informationshantering på internet är ett växande fenomen. Ett sätt för företag och organisationer att få ut information på internet är via webbplatser. För innehållshantering och utveckling av webbsidor så kan man använda content management system. Sådana system förenklar informationshanteringen på webbplatsens olika webbsidor. Det finns en uppsjö av CMS-verktyg och CMS-verktygen har stöd för olika funktioner. Den här studien är genomförd som en fallstudie där fallet som studeras är kriterier vid val av CMS-verktyg. Data har samlats in via enkäter och dokumentstudier. Kriterier har identifierats och prioriterats med hjälp av MoSCoW prioriteringsmetod av redaktörer och utvecklare som arbetar med CMS-verktyg. Prioriterade kriterier har sammanställts och ett urval av CMS-verktyg har utvärderats mot kriterierna. Utifrån insamlade data ifrån enkäter togs en prioriteringsordning fram som beskriver prioriterade kriterier vid val av CMS-verktyg. Det går att utskilja att somliga kriterier är viktigare än andra för redaktörer och utvecklare. Även visade dokumentstudien att de urvalet av CMS-verktyg som utvärderats uppfyllde majoriteten av kriterierna. / Information management on the Internet is a growing phenomenon.

O acesso a ambientes reais para simulação de smart grids está restrito a poucas universidades e empresas assim como existem poucas ferramentas disponíveis para sua simulação computacional, o que dificulta a realização de pesquisas nesta linha. Neste trabalho objetiva-se a configuração de um ambiente para simulação do protocolo DNP3 utilizando exclusivamente ferramentas open source, utilizando-se técnicas de segurança ofensiva para realizar ataques a rede e então validar o comportamento da simulação e por fim realizar a integração do ambiente de simulação com equipamentos reais. Para isso, foi desenvolvido um testbed virtual através da integração e configuração de diversas ferramentas e softwares open source e posteriormente utilizados os equipamentos do Laboratório de Proteção do Campus III na UNESP de Ilha Solteira, expandindo as funcionalidades do simulador e obtendo um testbed misto com resultados promissores em todos os testes realizados. / The simulation of computational environments is one of the main techniques applied in the study of protocols, the behavior of those protocols in computer networks, and the analysis of information security procedures. Research in the area of smart grid simulation is hampered by the fact that few universities and companies have access to real environments, and further, that the number of computational tools available is limited. This paper therefore aims to configure an environment for the simulation of the DNP3 protocol using exclusively open source tools and by applying offensive security techniques including attacks which seek to exploit network vulnerabilities; subsequently, the proposed simulation behavior is validated. For this purpose, a virtual testbed was developed by integrating and configuring various open source software and tools and later using the Campus III Protection Laboratory equipments at UNESP Ilha Solteira, expanding the simulator functionalities and obtaining a mixed testbed with results promising in all tests performed.
