Summary: According to design principles, adding concurrency to object-based programming courses does not have a negative impact on student learning, struggle, and engagement. By implementing simulations and assignments, students can experiment with concurrency extensions. Data evaluation results show that thread execution, creation, synchronization, and coordination have little or no significant effect on learning and engagement.

Summary: During software maintenance, continuous correction and enhancement activities are required. This often leads to high costs and time consumption, surpassing the initial developmental expenses. To manage software development and maintenance better, various measures of maintainability have been proposed. The Maintainability Index is commonly used to quantitatively assess the ease of software maintenance. An experiment conducted on 45 Java-based object-oriented software systems showed that the choice of maintainability index variant could impact the perception of maintainability. However, despite different values among variants, they were strongly positively correlated and generally indicated similar trends in maintainability evolution.

Summary: This study conducted a systematic mapping study to identify language features that claim to improve the implementation of object-oriented design patterns. The researchers found 18 language features that were claimed to improve design patterns and categorized them into paradigms. They also discovered that certain design patterns, such as Observer and Visitor, were more prevalent than others. Measures related to code size, code scattering, and understandability were preferred. This study provides a roadmap for future research on language features to improve object-oriented design patterns.

Summary: Research shows that challenges in continuous software development include difficulties in understanding informal documentation, the perception of documentation as wasteful, and a focus on short-term productivity. To address these challenges, practitioners are recommended to adopt practices like non-written communication and tools like architecture frameworks to improve the quantity and quality of documentation.

Summary: Identifying and understanding the artifacts that need to be changed during software maintenance is often costlier than applying the actual change. This paper proposes a metric for assessing the probability of one requirement being affected by a change in another requirement, focusing on the requirements level. The metric accounts for past co-change, overlapping implementations, and source code dependencies, and is validated through an industrial case study.

Summary: Technical debt refers to taking shortcuts in software development at the expense of long-term maintainability. Previous research has focused on identifying developer-reported technical debt, while this study proposes and evaluates an approach for automated identification of self-admitted technical debt (SATD) from multiple sources. The approach integrates source code comments, commit messages, pull requests, and issue tracking systems, achieving superior performance compared to baseline methods. The study also characterizes SATD in open-source projects and explores the relationships between SATD in different sources, revealing insights such as even distribution among sources and common keywords shared between issues and pull requests.

Summary: Technical debt refers to shortcuts taken during software development for the sake of expedience. Self-Admitted Technical Debt (SATD) occurs when developers explicitly acknowledge these shortcuts. While SATD management in Open Source projects has been studied extensively, its exploration in industry and developers' perspectives towards SATD have received limited attention. To address this gap, an exploratory case study was conducted with an industrial partner to understand how SATD is perceived and managed. The study involved collecting data on SATD from different sources and conducting interviews with 12 software practitioners. The results highlight the core characteristics of SATD in industrial projects, developers' attitudes towards it, triggers for its introduction and repayment, relations between SATD in different sources, practices used for its management, as well as challenges and tooling ideas.

Summary: Although Technical Debt (TD) has received increasing attention, most studies are based on single sources. This study investigates the management of TD across different sources and finds that most resolved TD items in issue trackers are also paid back in source code, although many are not further discussed. It is also discovered that the identification of TD items often takes a long time (around one year) but can be resolved quickly if the same developer is involved in the process.

Summary: A key aspect of technical debt management is measuring the accumulated principal. Existing approaches to estimate technical debt principal focus on architectural debt, but lack full automation, availability, and validation. This article proposes a novel approach using machine learning and architectural smells to estimate architectural technical debt principal, addressing shortcomings of current approaches. The approach applies information retrieval techniques to train a learning-to-rank machine learning model, calculates the number of lines of code creating the smell, and combines these values for the debt estimation, validated through a case study and interviews with practitioners.

Summary: The architecting of Systems of Systems (SoS) is an important topic that has gained increasing interest. However, the interplay between different disciplines involved in the architecting process is often overlooked, which has significant implications for integration and operational issues. In this research, the authors collaborated with practitioners in a large-scale radio astronomy SoS project to explore potential improvements in interface management by adopting elements of the documentation-as-code philosophy. The results and lessons learned from this study are reported in this paper.
