2023 IMPACT REPORT

Letter from our Executive Director

Leah Silen

I’m excited to share our 2023 Impact Report. It highlights the achievements and the collective efforts of our community. This year has been nothing short of remarkable. We supported our projects by providing access to critical funding, facilitating the work of volunteer committees dedicated to project health, and organizing events that strengthened and energized our community. These efforts allowed projects to continue reaching development milestones and promoting long-term sustainability. This year underscores the growing recognition of the critical role that open source scientific computing plays in advancing research and innovation across the globe. As we reflect on the past year, we do so with gratitude for the people who made it possible. Their efforts, support, and dedication drive us to continue our work for years to come.

In 2023, projects received over five million dollars through NumFOCUS, marking a pivotal moment in project sustainability. These funds, sourced from grants and generous donations, were instrumental in financing essential work such as maintenance, enhancing interoperability and standardization, training initiatives, and improving accessibility. An additional 3.5 million was dedicated to project services, advancing our core mission of supporting open source scientific computing projects and their communities. Amid rapid technological advancements and the growing prominence of AI and data in our daily lives, NumFOCUS initiatives broadened in scope and deepened in impact.

We expanded our community-led committees and worked to grow the impact of our existing committees. The Project Security Committee was introduced to enhance scientific computing security through risk assessments and recommendations for NumFOCUS projects. The Affiliated Project Selection Committee evaluated 48 applications, providing critical feedback and best practices. The Small Development Grants Committee distributed over $270,000 to support project growth and innovation. Our second DISC Unconference, organized by the Diversity in Scientific Computing committee, was a tremendous success, attracting 36 DEI leaders from 13 countries and producing DEI guidelines and resources for the open source community.
This year, our project communities continued to grow and fulfill their roadmaps, announcing over fifty new code releases. Projects participated in mentorship programs, organized events, facilitated diversity initiatives, and held office hours to connect with their communities. They published papers and collaborated on research projects that drove discovery and innovation at the forefront of science and technology. We congratulate code and non-code contributors on these efforts and are proud to direct resources toward their continued success.

Events are the pulse of our community, creating spaces for connection, collaboration, knowledge sharing, and innovation. Our events spanned the globe this year, offering in-person and online engagement through talks, tutorials, and workshops. With outreach extending to over 8,000 attendees and countless more through recorded content, the impact of these events continues to educate and inspire.

In closing, we thank the individuals deeply invested in the health and longevity of our project communities. We know our mission relies on the collaborative efforts of dedicated community volunteers, project contributors, donors, and staff members. Our heartfelt thanks to our staff for their relentless pursuit of efficiency and adaptability, our Board members for their visionary planning, the Advisory Council for invaluable insights, our volunteers for their invaluable service, and our donors for their unwavering support of our mission.

NumFOCUS 2023 Project Summit

Shared by Matthias Bussonnier from Project Jupyter

The NumFOCUS Project Summit 2023 was from September 11th to 13th. NumFOCUS is a US-based nonprofit that acts as a financial entity and support service provider for many projects in the Python ecosystem and more.

Every year, many projects send a few representatives to the NumFOCUS Summit for a couple of days, and this year the Summit was held near Amsterdam in the Netherlands. As this was in Europe, I could attend as one of the representatives of the Jupyter Project (and IPython).

The NumFOCUS summit was roughly structured as an unconference, with pre-scheduled sessions in the morning and allocated time in the afternoon for concurrent working groups. Those groups would be proposed in the morning and voted upon during lunchtime.

Here are some of my experiences attending the summit.

It was great having the summit in Europe, not only because it's less travel for some of the participants but because getting visas for countries in North America can be difficult. Not having any time-zone change (or at least only an hour or two) is way less tiring, at least for European attendees.

The Summit being in-person is, IMHO, important not only to meet with people you might already know online but also to have a chance to learn from and meet with contributors and maintainers from other projects. Many discussions happened outside of scheduled conference time and in smaller groups.

The unconference format is useful for bringing out topics that would likely not happen otherwise.

Topics Discussed-

This will, of course, be a biased view as I attended only some of the sessions and have my own interests.

Learning about NumFOCUS processes and challenges.

A few of the morning sessions were presented by NumFOCUS staff. The main point I got from those was that NumFOCUS had grown a lot since its inception, and the processes that worked when it was smaller don't scale with the current size. With more than 60 projects under its umbrella, like with many organizations, there are growing pains.

Unlike companies that have a certain uniformity, NumFOCUS works with many projects that each have their idiosyncrasies, making finding tools sometimes difficult.

I'm also happy to learn that NumFOCUS is working on changing its ticketing system for a more streamlined workflow of interaction between project members and NumFOCUS staff.

Unconference sessions
Security
We talked about many things related to security processes. One of the longer discussions was about the scoring of CVE assessment of impacts and review of the fixes. This is something that can be fairly difficult for maintainers not trained in security
There was some mention of the new NumFOCUS Security committee and what their role would be. The committee currently has 7 members, and its formation is still in process, but from the draft charter, the high-level role would be:
The Security Committee will improve the safety of research, data, and scientific computing communities by assessing and making recommendations to address cybersecurity-related risks in NumFOCUS sponsored projects.
From my experience as part of the Jupyter Security Committee, I think that having a role at the NumFOCUS level to centralize Security report reception, high-level triage, and forwarding to the relevant Project Maintainers and monitoring responses would be helpful to avoid duplicating this process at each project level.
Some discussions happened around the conflicting uprating modes of Security vs. open source and the difficulty it entails.
We wondered whether a security bug bounty program should be run at the NumFOCUS level and how to fund it.
Documentation
Another unconference session I participated in was the documentation one. This was less structured, but there were some good iterations.
One of my main feelings is that people are happy with sphinx, which is still widely used in the ecosystem. Many projects feel the limitation and have the impression we are trying to make sphinx do more and more things it was not meant to achieve in the first place. Should, for example API and Narrative docs use the same tools?
More questions were raised around the process of documentation and tooling to "verify" docs. How can we ensure docs are written? Rust project has tools for “docs coverage” Could we have this for Python? There was some mention of PEP 782, but many attendees are not familiar with it yet, as it is quite recent and still being written.
The session was finished with a wishlist of things that Sphinx or current tooling can not do (easily): - in IDEs, have documentation in the viewer that is as good as in the rendered docs - have multiple input types as first-class citizens (Sphinx is still very first-centric). For example, translation of notebooks breaks down easily - have documentation for all ecosystems under the same UI - break 1-1 connection between rst <-> html - not be limited by static HTML as an output, i.e., can I take all the existing docs and render it in, for example, a Single Page Application with dynamic rendering options. - reducing friction in writing documentation. Docusaurus mentioned as an example of another tool with a much faster rendering cycle but doesn't have "intersphinx" - numpydoc could be stricter to enforce more consistency across projects
We ended up creating a discord channel for documentation: https://discord.com/invite/vur45CbwMz
Academic Recognition and Licenses
Throughout the Summit I heard the familiar thread of lack of contribution recognition, particularly in the academic world. Academic careers rarely reward software contribution, and even when this is the case, new software contributions are preferred to existing ones.
Publications also often forgo software citation, and as usual, many discussions floated around this topic.
One thing that caught my attention was the discussion about Software Licensing and the question of the effects of having a license that includes a clause that software must be cited in an academic paper if used for given research. Funding sources often have such clauses that the institution giving money for research must be disclosed. Is the legal avenue one way to incentivise institutions to ensure software is cited?

The Open Source Science Initiative accelerated in our mission to connect users of open source research software with the development teams behind that software.
Development of the Map of Open Source Software (MOSS) began, supported by ongoing interest group calls in Healthcare and Life Sciences, Climate and Sustainability, and Chemistry. MOSS is an interactive, composable map of open-source research software that lets you explore the following five key questions:
Which open-source scientific software tools are available in any given domain?
Which tools produce what published research?
Who are the people behind both the papers and the tools?
Who funds development and maintenance of these papers and tools?
Which nodes in the system produce the greatest impact as defined by the user?
Learn more about MOSS and view some demos of the prototype at https://map.opensource.science
In September, we launched “Spotlight,” a new series where we present science-related OSS tools and the people and stories behind them. We want the series to shine a light on how open-source scientific software “gets done” while highlighting the outstanding tools that exist in the open-source research software ecosystem. The first three Spotlight posts were published in 2023, and we’re looking forward to seeing many more in 2024.
The team also connected with practitioners and developers at over 40 conferences and meetups around the world!
We look forward to next year as we continue MOSS development, expand our interest group support, and refresh our communications material including our website. For now, check out our Medium or subscribe to our newsletter for information on how to get involved with OSSci!
