O desenvolvimento de software é uma atividade intensive em esforço humano. Assim, a forma como os desenvolvedores encaram suas tarefas é de suam importância. Em um ambiente como o usual em projetos de FOSS (free/open source software) em que profissionais (desenvolvedores pagos) compartilham os esforços de desenvolvimento com voluntários, a moral da comunidade de desenvolvedores e usuários é fundamental. Neste artigo, apresentamos uma análise preliminary utilizando técnicas de análise de sentimentos realizada em um projeto de FOSS. Para isso, executamos a mineração da lista de endereços eletrônicos de um projeto e aplicamos as técnicas propostas aos participantes mais relevantes. Embora a aplicação seja limitada, no momento atual, experamos que essa experiência possa ser benéfica no future para determiner situações que possam afetar os desenvolvedores ou o projeto, tais como baixa produtividade, abandono do projeto ou bifurcação do projeto, entre outras.

Over Time

Most libre (free, open source) software projects rely on the work of volunteers. Therefore, attracting people who contribute their time and technical skills is of paramount importance, both in technical and economic terms. This reliance on volunteers leads to some fundamental management challenges: Volunteer contributions are inherently difficult to predict, plan, and manage, especially in the case of large projects. In this chapter we present an analysis of the evolution over time of the human resources in large libre software projects, using the Debian project, one of the largest and most complex libre software projects based mainly in voluntary work, as a case study. We have performed a quantitative investigation of data corresponding to roughly seven years, studying how volunteer involvement has affected the software released by the project, and the developer community itself.

In this chapter we investigate the potential of open source software to increase the impact of microfinance (MF) especially for the very poor. We argue that especially small and medium organizations play a crucial role, because they are more flexible in operations and familiar with the local context. We consider how new information and communication technology (ICT) can increase outreach of MF to the very poor within a self-sustainable holistic approach. We consider the potential of free/open source software projects to address the computing needs of small and remote MFIs, and we describe the reasons why no suitable solutions have emerged yet. While the use of FOSS and ICTs in general can help increase outreach, we feel the need to draw attention to the challenges that come with it; one should not forget that access to basic financial services is not all that is needed by the very poor.
