<p>The development of open source software has gone from a model characterized by skilled software developers that developed open source software for their own interest and their own needs to a model that is more business friendly and more attractive for companies and organizations. One new business model for open source software is the professional open source software model or OSS 2.0. The business model includes three roles: the open source project, the professional open source company and the user. This dissertation studies the relationship between these three roles and focuses on the development of the user role and how it may develop for a new user in a specific OSS ecosystem.</p><p>The roles in the eco system that has been studied are taken by the open source project Alfresco, the professional open source company Redpill and a user from a large international company, without any previous experience of open source software or the business model of professional open source. The result of the study showed a well developed eco system between the open source project and the professional open source company but a need of more information about the user’s role in it. Open source software is still seen by the user as an unsafe and unsecure alternative to the proprietary software available and more information about the business model of professional open source software and how the user can interact and influence the eco system is still needed.</p>

Programmers often have to choose components online for reuse based on software quality. To help with this choice, most component repositories (SourceForge, CodeProject, etc.) provide information such as user ratings and reviews of components. However, the reusability of components is not immediately obvious from this material. To make things worse, reviews and other material could potentially contradict one another about reusability or any other issue. Moreover, there could be multiple components that claim to perform identical tasks in which case it becomes difficult to identify the most reusable component. This thesis presents the result of two studies aimed at discovering how to use material from a component repository to automatically characterize the reusability of components. It was found that two factors (out of three) were significant predictors of reusability. Additionally, a review summarizer was developed to summarize user reviews and return the overall opinion reflected by the comments. / Graduation date: 2013

Recently, computational methods and software have been receiving more attention in the econometrics literature, emphasizing that they are integral components of modern econometric research. This has also promoted the development of many new econometrics software packages written in R and made available on the Comprehensive R Archive Network. This special volume on "Econometrics in R" features a selection of these recent activities that includes packages for econometric analysis of cross-section, time series and panel data. This introduction to the special volume highlights the contents of the contributions and embeds them into a brief overview of other past, present, and future projects for econometrics in R.

Research within the last fifteen years on global advocacy networks has often focused on their accomplishments through the linking of similar groups. The majority of this research while being useful to examine transnational political dynamics has two deficiencies. The first is that there is little or no consideration of the network infrastructure (from code to cables) that allows the aforementioned linkage to occur. It is therefore important to investigate the politics of infrastructure, architecture and design and the power and control thereof. Secondly, prior to Web 2.0. technologies, advocacy networks were nodes of information distribution, rather than nodes to which information was directed, and then subsequently collected, compiled and used for political purposes. It is quite reasonable to argue that Web 2.0. technologies (again due to considerations of code, digital architecture and design) have altered the manner in advocacy networks interact with their supporters, other organizations and formal political institutions. This change is located within the advocacy network’s technoorganizational structure. Subsequently, as the digital architecture for the internet is an inter-operable free/libre open source software (FLOSS) common to information exchange, it stands to reason that as an infrastructure this technology is directly a political landscape over which and in which friction and contestation can and does occur. In regard to the methods of interaction, FLOSS technologies have greatly expanded the pool of potential social activists and reduced the costs of engagement, activism and highlighting issues. With these factors in mind it can be argued that FLOSS has created opportunities for civil society to emerge and engage with society at large in ways that are both new (in a digital medium) and similar (tackling issues of social justice as constructed by the social activists). When considered at a systematic level this process has several implications. These implications include the impact of 4 networking on identity, social relations, power relations and so on, which in turn acknowledges that modern computer networking can act as a mechanism that radically restructures various political relations. This itself acknowledges various contests over modern computer networking (one position which is expressed by various FLOSS proponents), and the physical infrastructure and the power and control thereof which allows such networking to even exist in the first instance. Within this context, which could be described as an information ecosystem, there is a recognition that advocacy networks have emerged as new sources of power ready to exert influence through networking that occurs in a) a non formal manner and b) ‘beneath the radar’ as it were.

This study has been performed with an aim to provide an insight into how Node.js is used and the Node.js technology adaptation in the open source community. This research displays the diversity of Node.js and can inspire the reader to further development or continued research. Studies into different usages of Node.js have been missing in academic research and therefore this study gives a new, important insight into this technology. The authors used the exploratory case study methodology. For data collection, the authors created a JQuery and HTML script that fetched the desired dataset from Github and that were used as a static base for the study. Based on the usage areas extracted from the literature study, the authors specified different categories of usage. The dataset was manually investigated and placed into the categories, if they were relevant. The results show that web applications is by far the most well represented category with over 50% of all usages falling into this category. Network applications and Web servers come in at second and third position with 14% and 13% respectively. This study provided further categories and the authors could generate a set of diagrams, showing a trend on how the different usage areas changed from 2010 to 2015.

Based on collaboration rather than competition, Open Source Software provides a new dynamic in the development and use of software systems. As such it has the potential to make a significant legal, social and economic impact on the industry. While its origins trace back to the start of the software industry, the recent success of the Linux operation system, Apache web server or the Mozilla Firefox Internet Browser provide impetus to the growth of interest in this movement. However, while a number of studies have been conducted on its development, few have provided empirical evidence of its adoption within the South East Asian context. This study aims to investigate factors leading to the adoption of Open Source Software in Singaporean Organisations. The research has found that the adoption of Open Source Software is driven by the perception of a cost advantage. The organisations interviewed have acknowledged cost as being one of their biggest concerns and top priorities. While costs were stated to be of major concern to the organisations, objective measures of cost such as Total Cost of Ownership (TCO) and Return on Investment (ROI) were rarely used by the organisations studied. This perception of cost saving is found to be led by industry sources such as publications, conferences and websites. The next significant finding is the need for increased open source software skills in the industry. One of the major drivers of Open Source Software Adoption in the organisations is that they posses pre-existing skills in Open Source Software use. This enables them to better mitigate risk and to lower their training costs. The final principal finding is that Open Source Software appears to be used mainly in systems infrastructure applications. Organisations reported a large degree of satisfaction including increased stability, scalability and cost effectiveness. Issues remain with Open Source Software’s manageability, its quality of support and ease of use.
