Several refactorings performed while evolving software features aim to improve internal quality attributes like cohesion and complexity. Indeed, internal attributes can become critical if their measurements assume anomalous values. Yet, current knowledge is scarce on how developers perceive the relevance of critical internal attributes while evolving features. this qualitative study investigates the developers' perception of the relevance of critical internal attributes when evolving features. We target six class-level critical attributes: low cohesion, high complexity, high coupling, large hierarchy depth, large hierarchy breadth, and large size. We performed two industrial case studies based on online focus group sessions. Developers discussed how much (and why) critical attributes are relevant when adding or enhancing features. We assessed the relevance of critical attributes individually and relatively, the reasons behind the relevance of each critical attribute, and the interrelations of critical attributes. Low cohesion and high complexity were perceived as very relevant because they often make evolving features hard while tracking failures and adding features. the other critical attributes were perceived as less relevant when reusing code or adopting design patterns. An example of perceived interrelation is high complexity leading to high coupling.

Massive Open Online Courses (MOOCs) allow their participants to acquire knowledge in various fields, such as STEM, at low cost or for free, provided they have access to the Internet and a web-enabled device. this study investigates a critical phenomenon in STEM MOOCs: dropout rates from a gender perspective. Our objective is to identify retention factors of women in engineering and STEM MOOCs through a PRISMA-based Systematic Literature Review of conference papers and journal articles retrieved from IEEE Xplore and Scopus. Seventy-two papers were retrieved, of which 15 were relevant, withthe majority of the information pertaining to the strategies and best practices enhancing women's retention and engagement in STEM MOOCs. Gender socialization, lower self-efficacy and time constraints were the main dropout factors, although female students have been found to adapt more easily to digital learning environments. this comprehensive analysis aims to establish solid foundations for future MOOCs and academic studies on this topic.

Vulnerability datasets have become an important instrument in software security research, being used to develop automated, machine learning-based vulnerability detection and patching approaches. Yet, any limitations of these datasets may translate into inadequate performance of the developed solutions. For example, the limited size of a vulnerability dataset may restrict the applicability of deep learning techniques. In our work, we have designed and implemented a novel work-flow with several heuristic methods to combine state-of-the-art methods related to CVE fix commits gathering. As a consequence of our improvements, we have been able to gather the largest programming language-independent real-world dataset of CVE vulnerabilities withthe associated fix commits. Our dataset containing 26,617 unique CVEs coming from 6,945 unique Github projects is, to the best of our knowledge, by far the biggest CVE vulnerability dataset with fix commits available today. these CVEs are associated with 31,883 unique commits that fixed those vulnerabilities. Compared to prior work, our dataset brings about a 397% increase in CVEs, a 295% increase in covered open-source projects, and a 480% increase in commit fixes. Our larger dataset thus substantially improves over the current real-world vulnerability datasets and enables further progress in research on vulnerability detection and software security. We release to the community a 14 GB PostgreSQL database that contains information on CVEs up to January 24, 2024, CWEs of each CVE, files and methods changed by each commit, and repository metadata. Additionally, patch files related to the fix commits are available as a separate package. Furthermore, we make our dataset collection tool also available to the community.
