Show Notes

In this episode of Sustain, Richard Littauer sits down with Daniel Roe and Matias “Patak” Capeletto to talk about npmx, the community-built alternative interface for exploring the npm registry. They dive into how a small idea exploded into hundreds of contributors and thousands of pull requests, why the project intentionally puts people and community ahead of nonstop productivity, and how they’re approaching governance, inclusion, burnout, and sustainability. They also explore how npmx could make finding the right JavaScript packages easier, the challenges of funding a fast-growing open source project, and why healthy open source communities need much more than great code. Start listening now!

[00:02:22] Daniel explains what npmx is and what started in January 2026 quickly attracted dozens of pull requests, eventually growing to hundreds of contributors and a large Discord community.

[00:05:44] They discuss modern web technology, Algolia powered search, dark mode, expanded download graphs, package comparisons, and other improvements contributed by the community, and about building around people instead of productivity.

[00:09:58] Matias shares the open source project that went on vacation.

[00:14:36] Daniel and Matias talk about managing disagreements, establishing a code of conduct, separating developer and user communities, and why shared values and inclusion are essential to the project.

[00:18:43] Matias explains npmx’s connection to the Ecosystem Performance community and how the site can surface modern or better-maintained alternatives instead of relying only on package popularity.

[00:22:52] Rather than trying to support every programming ecosystem, Daniel talks about making npmx smarter within JavaScript and TypeScript.

[00:26:54] They discuss sponsorships, grants, company partnerships, conferences, and the eventual need to fund one or two developers full-time if the project is going to thrive long term.

[00:29:58] Daniel explains why open source needs more programmers.

[00:31:54] Find out where you can go online to learn more and help with projects at npmx.

Quotes

[00:08:53] “It was very special for a lot of us that were a little lost with that connection and all the noise from companies telling people they’re going to be replaced.”

[00:11:37] “You are the thief of joy.”

[00:13:03] “That was a side effect of people having fun with their friends that they were meeting for the first time online.”

[00:16:56] “Everybody that shares our values is welcome, but it’s not that everyone is welcome by itself.”

[00:30:07] “I don’t think OSS is a business.”

Spotlight

[00:33:18] Richard’s spotlight is the book, With a Bird: A Reader on Avian Kinship and his digital alarm clock.

[00:34:02] Daniel’s spotlight is the game, Clues by Sam.

[00:34:35] Matias’s spotlight is the tool, AgentScan.

“Today we’re launching the Software Stewardship Lab.” - Vlad-Stefan

In this episode, Richard, Abby, and Eriol welcome Vlad-Stefan Harbuz - University of Edinburgh PhD student, Executive Director of the Software Stewardship Lab, and Director of the Open Source Pledge - to talk about the Open Source Pledge and the newly launched Software Stewardship Lab. They discuss how companies can better support the open source software they depend on, why it can be difficult to know where funding should go, and how the lab hopes to address issues like software security, hidden dependencies, and maintainer burnout. Press download now to hear more!

[00:02:03] Richard introduces Vlad and his background, and Vlad shares his path into open source research.

[00:03:30] Vlad explains how the Open Source Pledge works.

[00:06:17] The conversation turns to how the funding goes directly to maintainers.

[00:07:57] Vlad discusses why open source funding becomes a popularity contest.

[00:10:05] We hear about challenges for large companies joining the pledge.

[00:13:16] Vlad tells us about the Software Stewardship Lab.

[00:15:09] The conversation highlights the importance of design, user experience, copywriting, localization, data collection, and other essential work that is frequently overlooked or poorly funded.

[00:17:59] Vlad discusses potential partnerships with the Software Sustainability Institute and researchers studying open source, research software, and community health.

[00:20:58] We hear how the lab plans to fund its work and the hidden risk of binary dependencies.

[00:25:49] The lab’s work extends beyond dependency mapping to research on maintainer burnout, the effects of AI, mental health, and governance structures that encourage sustainable participation.

[00:28:48] Vlad urges employees and decision-makers to recognize that supporting open source is both a public good and a practical business investment that can prevent critical infrastructure from breaking.

Quotes

[00:09:12] “These metrics are at best proxies currently.”

[00:17:47] “We need more educational resources to show people that this stuff is really important and it’s not just lines of code.”

[00:28:19] “It’s about creating a larger space that focused on more general questions in open source sustainability.”

[00:28:53] “I would like to tell people that work for large companies to tell their employers that their corporate commercial work relies more on open source software that people develop for free in their free time, the work is tremendously important for their business, and there are other organizations that are doing work to help create resources to make this infrastructure more sustainable.”

[00:29:31] “Try to convince your boss that this stuff is worth funding, and not just for the social good! It’s also in the company’s interest, so you have two very good reasons to do it.”

Show Notes

In this episode of Sustain, Richard talks with Chelsea Finnie, Chairperson of Python New Zealand and a Senior Network DevOps Engineer at REANNZ, about the serious behind-the-scenes work required to keep open source communities alive. Chelsea shares how they moved from Python conference volunteer to community leader, then walks through Python New Zealand’s financial crisis after discovering improper use of funds, the legal and governance challenges that followed, and how Linux Australia helped keep the organization and Kiwi PyCon alive. It’s a candid conversation about trust, accountability, burnout, community rescue, and why open source leadership is about much more than code. Press download now to hear more!

[00:01:47] Chelsea explains their work at REANNZ and their role as a senior network DevOps engineer including Python-based network automation and the PANDA initiative for advancing network device automation.

[00:03:08] Chelsea talks about contributing an open source “glue” service connecting Prometheus Alertmanager to Argus using Flask.

[00:04:21] Chelsea takes us through how they got involved with Python New Zealand, helping rescue AV production for a Kiwi PyCon event, and realizing they might be capable of helping run a conference themselves.

[00:06:58] They share the lighter side of joining the Python NZ committee, including a sea shanty lightning talk and an election promise to write a Python-based sea shanty.

[00:08:35] Richard shifts into the central issue: Python New Zealand leadership had been dealing with a major financial and governance crisis and Chelsea explains discovering the budget hole, seeking legal advice, reviewing the transactions, and what happened when Linux Australia stepped in.

[00:14:43] Chelsea reflects on Linux Australia’s role as a lifeline and why having financially stable open source organizations matters.

[00:15:46] Richard highlights the often-overlooked legal and financial responsibility that comes with serving on nonprofit or open source boards and Chelsea shares where Python NZ stands now.

[00:18:26] They tell us about the new safeguards and governance checks and notes that better accounting systems, such as Xero, would likely have exposed the financial problems earlier

[00:20:31] Chelsea shares how they stay motivated through heavy work and the value of open source leadership.

[00:21:57] Richard points out that Chelsea was not only helping fix financial and governance issues but also continuing to lead Python New Zealand and run events. Chelsea talks about the decision to run Kiwi PyCon on the “West Island.”

[00:25:08] Chelsea says one of their goals as chairperson is to identify and support the next people who will lead Python New Zealand and future events.

[00:26:14] Richard closes by encouraging listeners to get involved in their local open source communities, whether Python New Zealand or any other regional group.

At UN Open Source Week in New York, Richard hosts a short, on-the-fly Sustain mini-episode from IBM’s offices with Andrew Nesbitt of Ecosyste.ms, a registry-of-registries built from dependency data across 300 million repositories. Nesbitt explains how that data is being used to prioritize security scanning with new AI models, revealing that many heavily used but dormant transitive dependencies—often unseen and unaudited—are high risk; in his testing of about 3,000 critical, abandoned projects across multiple ecosystems, roughly 50% had serious vulnerabilities, including logic flaws that can chain across dependency trees. He warns that LLMs accelerate both discovery and exploitation, shrinking traditional 90-day disclosure windows to effectively zero. They urge developers to prune and update dependencies and devices promptly, and to support maintainers respectfully—financially or with broader help—amid vulnerability floods and initiatives like the “Summer of Bliss.”

Show Notes

In this episode of Sustain, Richard welcomes back Courtney Miller to unpack her PhD research on one of open source’s most overlooked problems: what happens when widely used software is abandoned. Courtney explains why abandonment is not always simple, or even always bad, but can create real risks for the developers and projects that depend on it. From npm package research and downstream impact to Abandabot, AI-assisted tooling, maintainer burnout, and responsible sunsetting, this conversation explores how the open source ecosystem can better understand, detect, and respond when the software we rely on stops being maintained. Press download now!

[00:01:28] Courtney explains the focus of her dissertation.

[00:02:34] Courtney defines abandonment.

[00:03:44] Her ecosystem-wide analysis focused on the npm JavaScript ecosystem, looking specifically at widely used packages.

[00:05:23] The first part of the dissertation involved interviews with maintainers who rely on abandoned packages and often lack tools or clear processes for responding.

[00:06:31] Courtney describes two types of abandonment: Explicit Notice Abandonment and Activity Based Abandonment.

[00:09:27] Courtney explains the third and final chapter called, Designing Abandabot.

[00:11:10] Richard raises the point that some software can be “done” and still function fine. Courtney agrees, noting that not all abandonment matters and beyond alerts remediation matters.

[00:13:22] The conversation expands into under-resourced and under-maintained projects, which can also become supply chain risks before they are fully abandoned.

[00:14:53] Richard brings up the “Whale Fall” idea and Courtney agrees and points to responsible sunsetting as an important research area.

[00:17:39] We learn about Courtney’s experience bringing AI into the dissertation, especially for building Abandabot’s prediction system.

[00:20:54] Richard asks whether AI is already making abandonment more common.

[00:24:52] Courtney talks about staying grounded in real practitioner problems as the open source and AI landscape changes quickly.

[00:26:30] Final Takeaways: Courtney argues that abandonment needs to be addressed now, especially through software composition analysis tools that can help developers understand and respond to real dependency risk.

Quotes

[00:01:35] “The title of my dissertation is: “Supporting the Sustainable Use of Open Source Software.”

[00:07:10] “There is no right answer how to define abandonment.”

[00:07:26] “Explicit Notice Abandonment”- where the maintainers of a package publicly express their intent to no longer do so.”

[00:07:42] “The other type of abandonment was called “Activity Based Abandonment” -commonly used as a way of identifying abandonment in open source sustainability literature.”

[00:08:26] “Out of the widely used packages, around 15% had abandonment issues.”

[00:11:38] “Not all abandonment matters. If left pad is abandoned, who cares?”

[00:21:35] “Maybe projects never have to die. You can create a fork and maintain it on your own.”

Spotlight

[00:27:20] Richard’s spotlight is the translation feature on iPhone in Books.

[00:28:20] Courtney’s potlight is her dog, Chanel, and SAFE-MCP.
