The Evolution of Stack Overflow Posts: Reconstruction and Analysis [article]

Sebastian Baltes, Lorik Dumani, Christoph Treude, Stephan Diehl
2018 arXiv   pre-print
Stack Overflow (SO) is the most popular question-and-answer website for software developers, providing a large amount of code snippets and free-form text on a wide variety of topics.  ...  Based on different analyses using the dataset, we present: (1) insights into the evolution of SO posts, e.g., that post edits are usually small, happen soon after the initial creation of the post, and  ...  Acknowledgements The authors would like to thank Florian Reitz for his help with database-related issues and Tobias Zeimetz for creating the post history ground truth.  ...

An empirical study of question discussions on Stack Overflow [article]

Wenhan Zhu, Haoxiang Zhang, Ahmed E. Hassan, Michael W. Godfrey
2021 arXiv   pre-print
On Stack Overflow, discussions through comments and chat rooms can be tied to questions or answers. In this paper, we conduct an empirical study that focuses on the nature of question discussions.  ...  Our findings suggest that question discussions contain a rich trove of data that is integral to the Q&A processes on Stack Overflow.  ...  Our analysis is based on the data dump of Stack Overflow from December 2018 (the comment dataset) and web crawling in June 2019 (the chat room dataset).  ...

M. Santander-García, D. Jones, J. Alcolea, V. Bujarrabal, R. Wesson
2021 arXiv   pre-print
Reconstruction of the CE of four objects suggests that the mass of SD nebulae actually amounts to a very small fraction of the envelope of their progenitor stars.  ...  We aim at testing this hypothesis by investigating the mass of a sample of 21 post-CE PNe, ~1/5th of the known total population, and comparing them to a large sample of 'regular' (i.e. not known to host  ...  This work has made use of data from the European Space Agency (ESA) mission Gaia (https://www. cosmos.esa.int/gaia), processed by the Gaia Data Processing and Analysis Consortium (DPAC, https://www.cosmos.esa.int  ...
