Nowadays, a global information infrastructure connects remote parties through the use of large scale networks, and many companies focus on developing e-services based on remote resources and on interactions between remote parties. In such a context, e-government (e-gov) systems became of paramount importance for the public administration, and many ongoing development projects are targeted on their implementation, security, and release (Bettini, Jajodia, Sean Wang, & Wijesekera, 2002). For open-source software to play an important role in this scenario, three main technological requirements must be fulfilled: (1) the identification and optimization of de facto standards for building e-gov open-source software components, (2) the adoption of open-source techniques to secure e-gov services and (3) the standard integration of these components into an open-source middleware layer, capable of conveying a completely open-source e-gov solution. This article highlights that e-gov systems should be constructed on an open-source middleware layer, providing full public responsibility in its development. The role of open-source middleware for secure e-gov services deployment is discussed, focusing on implementing a security environment without custom programming. An alternative solution is given and consists of the adoption of a stand-alone architecture that fulfils all security requirements.

As Free and Open Source Software (FOSS) increases in importance and use by global corporations, understanding the dynamics of its communities becomes critical. This paper measures up to 21 years of activities in 1314 individual projects and 1.4 billion lines of code managed. After analyzing the FOSS activities on the projects and organizations level, such as commits frequency, source code lines, and code comments, we find that there is less activity now than there was a decade ago. Moreover, our results suggest a greater decrease in the activities in large and well-established FOSS organizations. Our findings indicate that as technologies and business strategies related to FOSS mature, the role of large formal FOSS organizations serving as intermediary between developers diminishes.

Abstract A well-known way to help newcomers overcome initial contribution challenges is mentoring. This strategy has proven effective in offline and online communities, and to some extent has been employed in Open Source Software (OSS) projects. Through mentoring, newcomers are trained to acquire the technical, social, and organizational skills they need. Despite the importance of OSS mentors, they are under studied in the literature. Understanding who mentors in OSS projects are, the challenges they face, and the strategies they use can help OSS projects better understand and support mentors' work. In this paper, we investigate the OSS mentors' perspectives by employing a two-stage study. First, we understand the characteristics of the mentors in a large OSS community through a large-scale online survey in the Apache Software Foundation. We found that contributors who are volunteers and less experienced are less likely to take on the role of mentoring. Second, we identify the challenges that mentors face and how they mitigate these challenges through interviews with OSS mentors (n=18). In total, we identified 25 general mentorship challenges and 7 sub-categories of challenges regarding task recommendation. We also identified 13 strategies to overcome these challenges. Our results provide insights for OSS communities, formal mentorship programs like Outreachy, and tool builders who design automated support for task assignment and internship.

Reflection about the role of community engagement and corporate social investment in Brazil, associated with the presence of a large economic enterprise, is the major stimulus of this chapter. It seeks to present how cross-sector governance can contribute to the social development of a city and how this process can be led by a partnership comprising a corporate foundation, government, and civil society. The concept of the public–private social partnership (PPSP) is explored: a strategy for building a series of inter-sectoral alliances aimed at promoting the sustainable development of territories where the company has large-scale enterprises, through joint efforts towards integrated long-term strategic planning, around a common agenda. To this end, the case of Canaã dos Carajás is introduced, a municipality in the State of Pará, in the Amazon region, where large-scale mining investment is being carried out by the mining company Vale SA.

AbstractThe PRISMS-Fatigue open-source framework for simulation-based analysis of microstructural influences on fatigue resistance for polycrystalline metals and alloys is presented here. The framework uses the crystal plasticity finite element method as its microstructure analysis tool and provides a highly efficient, scalable, flexible, and easy-to-use ICME community platform. The PRISMS-Fatigue framework is linked to different open-source software to instantiate microstructures, compute the material response, and assess fatigue indicator parameters. The performance of PRISMS-Fatigue is benchmarked against a similar framework implemented using ABAQUS. Results indicate that the multilevel parallelism scheme of PRISMS-Fatigue is more efficient and scalable than ABAQUS for large-scale fatigue simulations. The performance and flexibility of this framework is demonstrated with various examples that assess the driving force for fatigue crack formation of microstructures with different crystallographic textures, grain morphologies, and grain numbers, and under different multiaxial strain states, strain magnitudes, and boundary conditions.

Purpose: Engineering, procurement, and construction (EPC) contracts are on their way to becoming the most common type of contract used by the private sector for large-scale infrastructure projects. Every project requires a strong relationship between all of the experts participating in EPC projects and the client. This relationship must be solidly established by an architect; otherwise, the project may fail for all parties involved, including the client, contractor, lenders, government, and others. The purpose of this study is to identify if the working of the EPC contracts is favourable for the architectural profession, and to identify the way in which the working could be improved. Methodology: A qualitative approach was applied to analyze the critical points of EPC contracts based upon reviews of related case studies from the public sector and supplementary interviews with professionals in the field. Main Finding: The architect's role in an EPC contract is not crucial and is equal to other stakeholders involved in the project. Also, EPC contractors have the power to dictate the workflow of the project and hence, architects might have to compromise in terms of the design, compensation, etc. Implications: It is very important for every project to have an outcome based on each stakeholders/consultants inputs specially on larger projects, this article is a step towards understanding the role of architects under an EPC contract as the future projects will come under its purview.  Novelty: The study is done under the lens of a newly graduated architect and not as any other professional, thereby trying to develop an understanding for fresh architects.

Modern cell phones are required to receive and display alerts via the Wireless Emergency Alert (WEA) program, under the mandate of the Warning, Alert, and Response Act of 2006. These alerts include AMBER alerts, severe weather alerts, and (unblockable) Presidential Alerts, intended to inform the public of imminent threats. Recently, a test Presidential Alert was sent to all capable phones in the U.S., prompting concerns about how the underlying WEA protocol could be misused or attacked. In this paper, we investigate the details of this system and develop and demonstrate the first practical spoofing attack on Presidential Alerts, using commercially available hardware and modified open source software. Our attack can be performed using a commercially available software-defined radio, and our modifications to the open source software libraries. We find that with only four malicious portable base stations of a single Watt of transmit power each, almost all of a 50,000-seat stadium can be attacked with a 90% success rate. The real impact of such an attack would, of course, depend on the density of cellphones in range; fake alerts in crowded cities or stadiums could potentially result in cascades of panic. Fixing this problem will require a large collaborative effort between carriers, government stakeholders, and cellphone manufacturers. To seed this effort, we also propose three mitigation solutions to address this threat.
