Constructing Temporal Networks of OSS Programming Language Ecosystems

One of the primary factors that encourage developers to contribute to open source software (OSS) projects is the collaborative nature of OSS development. However, the collaborative structure of these communities largely remains unclear, partly due to the enormous scale of data to be gathered, processed, and analyzed. In this work, we utilize the World Of Code dataset, which contains commit activity data for millions of OSS projects, to build collaboration networks for ten popular programming language ecosystems, containing in total over 290M commits across over 18M projects. We build a collaboration graph representation for each language ecosystem, having authors and projects as nodes, which enables various forms of social network analysis on the scale of language ecosystems. Moreover, we capture the information on the ecosystems' evolution by slicing each network into 30 historical snapshots. Additionally, we calculate multiple collaboration metrics that characterize the ecosystems' states. We make the resulting dataset publicly available, including the constructed graphs and the pipeline enabling the analysis of more ecosystems.Comment: Accepted to SANER 202

Morphofunctional markers of kinetic aptitude in a sport selection system

In the article we study morphofunctional markers of sportsmen kinetic aptitude as one of the criteria for sport selection and sporting achievements prediction. The article contains various renderings of sport selection, shows its stages as a united system based on the hierarchy principle and targeted approach. It also extends different scientific views on the young people sporting aptitude detecting. The article reveals separate results of the diversified long-term researches (1965–2016) on the issues of physical and training load optimization in athletes of various sports taking into consideration their constitutional type (morphofunctional marker). Experimental materials are proved by high sporting achievements of Greco-Roman wrestlers and speed underwater swimmers. The study broadens the scientific knowledge about the opportunities of athlete perspective determination by means of morphofunctional criteria (markers) not only in a particular sport, but at the stage of his specialization
