A Platform-Based Software Design Methodology for Embedded Control Systems: An Agile Toolkit
A discrete control system, with stringent hardware constraints, is effectively an embedded real-time system and hence requires a rigorous methodology to develop the software involved. The development methodology proposed in this paper adapts agile principles and patterns to support the building of embedded control systems, focusing on the issues relating to a system's constraints and safety. Strong unit testing, to ensure correctness, including the satisfaction of timing constraints, is the foundation of the proposed methodology. A platform-based design approach is used to balance costs and time-to-market in relation to performance and functionality constraints. It is concluded that the proposed methodology significantly reduces design time and costs, as well as leading to better software modularity and reliability
Report on the Third Workshop on Sustainable Software for Science: Practice and Experiences (WSSSPE3)
This report records and discusses the Third Workshop on Sustainable Software
for Science: Practice and Experiences (WSSSPE3). The report includes a
description of the keynote presentation of the workshop, which served as an
overview of sustainable scientific software. It also summarizes a set of
lightning talks in which speakers highlighted to-the-point lessons and
challenges pertaining to sustaining scientific software. The final and main
contribution of the report is a summary of the discussions, future steps, and
future organization for a set of self-organized working groups on topics
including developing pathways to funding scientific software; constructing
useful common metrics for crediting software stakeholders; identifying
principles for sustainable software engineering design; reaching out to
research software organizations around the world; and building communities for
software sustainability. For each group, we include a point of contact and a
landing page that can be used by those who want to join that group's future
activities. The main challenge left by the workshop is to see if the groups
will execute these activities that they have scheduled, and how the WSSSPE
community can encourage this to happen
Should I Bug You? Identifying Domain Experts in Software Projects Using Code Complexity Metrics
In any sufficiently complex software system there are experts, having a
deeper understanding of parts of the system than others. However, it is not
always clear who these experts are and which particular parts of the system
they can provide help with. We propose a framework to elicit the expertise of
developers and recommend experts by analyzing complexity measures over time.
Furthermore, teams can detect those parts of the software for which currently
no, or only few experts exist and take preventive actions to keep the
collective code knowledge and ownership high. We employed the developed
approach at a medium-sized company. The results were evaluated with a survey,
comparing the perceived and the computed expertise of developers. We show that
aggregated code metrics can be used to identify experts for different software
components. The identified experts were rated as acceptable candidates by
developers in over 90% of all cases
An Approach to Transform Public Administration into SOA-based Organizations
Nowadays, Service-Oriented Architectures (SOA) is widely spread in private organizations. However, when transferring this knowledge to Public Administration, it is realized that it has not been transformed in terms
of its legal nature into organizations capable to operate under the SOA paradigm. This fact prevents public
administration bodies from offering the efficient services they have been provided by different boards of
governments. A high-level framework to perform this transformation is proposed. Taking it as starting
point, an instance of a SOA Target Meta-Model can be obtained by means of an iterative and incremental
process based on the analysis of imperatives and focused on the particular business context of each local public administration. This paper briefly presents a practical experience consisting in applying this process
to a Spanish regional public administration.Junta de Andalucía TIC-578
