Multiple Releases

Do developers postpone fixing Technical Debt (TD) in software systems? TD is a metaphor that refers to short-term decisions in software development that may affect the cost of the software development life cycle. The bad smell is an imperfect solution in the software system that negatively impacts the internal software quality and maintainability. In this paper, we will study five open-source software projects (OSSPs) that have several releases and also estimate the numbers of architecture smells (ASs), design smells (DSs), and code smells (CSs) for every release. Designite will be used to detect smells. We describe a case study conducted to explore the following: (1) What is the average smells density for architecture, design, and code smells in an OSSP? (2) Does the density of each smell type increase over multiple releases? (3) What percentage of each smell-type density is eliminated by refactoring? We collected around 2 million LOC from five OSSPs that have multiple releases from the GitHub repository to statistically analyze the software concerning the smells as indicators of TD. We find 36% of Architecture Technical Debt (ATD) is Cyclic Dependency, while 33% of Design Debt (DD) is Cyclically-dependent Modularization. More than 70% of Code Debt (CD) is Magic Number. Even though the developers do refactoring between releases, the TD density in general increases. On average, by refactoring, developers remove around 48%, 16%, and 22% from the introduced ATD, DD, and CD from their next release, respectively.

A Site

Geophysical methods can be helpful in mapping areas of contaminated soil and groundwater. Electrical resistivity and very low‐frequency electromagnetic induction (VLF) surveys were carried out at a site of shallow hydrocarbon contamination in Utah County, Utah. Previously installed monitoring wells facilitated analysis of water chemistry to enhance interpretation of the geophysical data. The electrical resistivity and VLF data correlate well, and vertical cross‐sections and contour maps generated from these data helped map the contaminant plume, which was delineated as an area of high interpreted resistivities.

Fuel Storage

A group of World War II naval fuel storage tanks strategically located in a tropical rainforest in Cairns, Australia, were adapted for arts and cultural purposes. This paper explores the adaptive reuse of this unusual industrial heritage site. It uses a case study approach to demonstrate how the social and aesthetic values of the place have been conserved and grown, and how these values have interacted to increase community attachment through a community-initiated approach to the site’s reuse. A scoping review and secondary data helped develop the case study and informed semi-structured interview questions for key industry stakeholders. The paper deduces that a community-led bottom-up approach to the reuse of space for arts and culture results in greater community attachment and, as opposed to top-down approaches, allows for continued growth in social and aesthetic value. Nevertheless, ongoing success of community initiatives in most cases is also reliant on the structure of a government-led administration.
