CHAOSScast
This CHAOSS Community podcast features members who spent considerable time and effort to understand open source community health and how we can measure it through metrics, analytics, and software. We invite guests to this podcast to talk about how they use open source community health metrics and software in their own open source communities, companies, or foundations. This podcast fills the gap with open source community metric definitions and software on one side and their use on the other side.

[00:00:31] The guests introduce themselves and their backgrounds.
[00:03:31] Yaya tells us the brief history of CHAOSS Asia that started in 2020.
[00:05:09] Divya talks about the growth and strategy of CHAOSS Asia and how it shifted to broader community engagement and partnerships.

[00:09:24] Divya shares plans for 2025 to include creating a database of open source communities in Asia.
[00:11:02] Yaya dives into some challenges such as cultural and language barriers, CHAOSS is more research-focused, and the need for localized, language-accessible discussions and events.
[00:13:18] Divya brings up awareness being a huge challenge when it comes to the CHAOSS project because many assume CHAOSS is only about non-technical/community work and region-specific tailored outreach is necessary.
[00:15:29] Harmony asks about the current focus in CHAOSS Asia and Divya shares increasing awareness through virtual meetups, conference talks, and partnering with organizations.
[00:16:40] Leon speaks about the social media and language inclusion presence with CHAOSS Asia managing Twitter and LinkedIn and considering localized subgroups for language-specific events.

Value Adds (Picks) of the week:
[00:25:24] Harmony’s pick is mentorship.
[00:26:17] Divya’s pick is her two cats.

Thank you to the folks at Sustain for providing the hosting account for CHAOSSCast!
CHAOSScast- Episode 107
In this episode of CHAOSScast, we have a special crossover episode with Sustain, hosted Richard Littauer. Richard chats with CHAOSS contributor Sean Goggins, a tenured full Professor of Computer Science at the University of Missouri. Sean discusses his extensive involvement in the open source community, particularly through his work with the CHAOSS Project, a Linux Foundation initiative focused on understanding and improving open-source project sustainability. Their conversation covers Sean's academic background, his role in CHAOSS, the importance of distributed leadership, and how metrics can impact the sustainability of open source projects. Sean also shares insights into his teaching methods, the challenges of maintaining open source software, and the future direction of his work on CHAOSS and Augur. Hit the download button now!
[00:02:32] Sean shares that he’s a professor specializing in software engineering, algorithms, data science, and visualization, and he discusses his tenure status and passion for research and open source work.
[00:03:48] Sean explains how open source leadership is distributed rather than centralized.
[00:05:52] We hear how the CHAOSS Project emerged from studying open source governance and leadership. Sean and Matt Germonprez started working on open source collaboration data and a metrics-focused discussion at a Linux Foundation Summit that led to the founding of the CHAOSS Project in 2017.
[00:09:30] Richard asks Sean how he balances research, teaching, and open source. Sean discusses how he splits time between research (40%), teaching (40%), and service (20%), with CHAOSS being a major part of his research efforts.
[00:14:34] Sean explains that the Augur Project was born out of a need for structured open source data tracking.
[00:16:25] Richard asks Sean if he teaches his students about open source, and he explains that he uses CHAOSS and Auger to teach students about GitHub collaboration, pull requests, and open source workflows.
[00:20:32] Sean shares his insights on research and open source. He emphasizes his involvement in maintaining software and aiding organizations in making sense of CHAOSS metrics through Augur, which has given him a deep understanding of open source development.
[00:21:51] Sean explains why he thinks metrics help make projects more sustainable and how the CHAOSS community has benefitted from fostering a welcoming environment for both technical and non-technical contributors.
[00:26:30] We hear some challenges within CHAOSS where it’s been difficult to build a strong developer community around CHAOSS software tools and maintaining open source software requires significant effort.
[00:29:18] He goes further to explain how to be a better project and that there’s potential for improving project sustainability through structured mentoring and governance.
[00:36:14] Sean shares CHAOSS Project’s future and research goals.

Episode 106: Funding Impact Measurement Working Group
Thank you to the folks at Sustain for providing the hosting account for CHAOSSCast!
CHAOSScast – Episode 106
In this episode of the CHAOSScast, host Alice Sowerby introduces guests Dawn Foster, Cailean Osborne, and Paul Sharratt to discuss the newly formed 'Funding Impact Measurement Working Group' within the CHAOSS community. The panel explores the group's origins, goals, and objectives, emphasizing the importance of mixed method approaches to assess the impact of funding on open source projects. They highlight the significance of both quantitative and qualitative methods to understand the effects of funding better and share insights on creating standardized frameworks for impact assessment. The discussion also touches on the challenges of public versus private funding, the nuances of financial support in open source projects, and the potential benefits of having a collaborative, open forum for related discussions. Hit download now to hear more!
[00:02:55] Dawn explains the newly established ‘Funding Impact Measurement Working Group’ within the CHAOSS Project including its goals and how often they meet.
[00:04:26] Paul describes how the working group was founded after a research paper was written on measuring the impact of public funding on open source and how they presented at Open Forum Academy at Harvard Business School.
[00:07:20] Dawn highlights open source funding comes from different sources and more about Microsoft’s FOSS Fund and measuring the impact of corporate sponsorship.
[00:10:25] Cailean outlines all the core objectives of the working group.
[00:13:17] We hear about the working group’s first meeting, including members from Digital Infrastructure Insights Fund, and the plan to build a repository of funding models, their effectiveness, and key case studies.
[00:15:34] There’s a discussion on the challenges in measuring funding impact, which Dawn explains cases where funding has led to community conflicts (some contributors get paid while others remain unpaid).
[00:19:45] Cailean talks about the long-term vision for the group which is expanding participation across different funding sources and building open source tools (e.g., Python scripts, Jupyter Notebooks) to support funding impact assessments.
[00:21:26] Dawn encourages participation in a working group by contributing in various ways, whether through technical resources, providing insights and experiences related to funding impacts, or simply learning and engaging in discussions.
[00:23:42] Paul and Cailean emphasize the need for qualitative research alongside quantitative metrics. Policymakers often seek “hard numbers,” but contextual insights from interviews and case studies are crucial.
Value Adds (Picks) of the week:
[00:29:12] Cailean’s pick is Audrey Tang at RightsCon on her dual meaning of digital in Chinese.
