Reflecting on Five Years as the PSF’s First CPython Developer in Residence

After nearly five wonderful years at the Python Software Foundation as the inaugural CPython Developer in Residence, it's time for me to move on. I feel honored and honestly so lucky to have had the opportunity to kick off the program that now includes several wonderful full-time engineers. I'm glad to see the program left in good hands. The vacancy created by my departure will be filled after PyCon US as the PSF is currently focused on delivering a strong event. I'm happy to share that Meta will continue to sponsor the CPython Developer in Residence role at least through mid-2027. The program is safe.

As a member of the Python Steering Council during Łukasz’s tenure as Developer in Residence, I express my personal gratitude for his dedication to the CPython project and the larger Python community. I know I echo the sentiment of everyone who has served on the Council during his time as DiR. He has defined what it means to be a Developer in Residence - a position that is incredibly important to the smooth operation of the CPython project, in large and small ways, visible and hidden. Our bi-weekly meetings gave the Steering Council a detailed, unique, and invaluable contemporaneous perspective on what’s happening in CPython. Łukasz leaves big shoes to fill, and we wish him all the best in his next endeavor. It’s comforting to know that he will continue to be a Python leader and member of the core team.

In my time as a developer in residence, I personally touched some pretty amazing projects like the transition to GitHub issues from bugs.python.org, the replacement of the mostly manual CLA process with an automated system, the introduction of free threading to Python, and the replacement of the interactive shell in the interpreter. And between the thousands of pull requests I've reviewed or authored, and the many less glamorous tasks like content moderation and keeping the lights on when it comes to core workflow, I've interacted with some amazing individuals. Some of them are core developers now. I've witnessed the full-time paid developer in residence roster at the Python Software Foundation grow from one person to five.

As for me, ever since seeing it for the first time in 2013, I had dreamed about moving permanently to Vancouver BC. This dream is coming true soon. As part of that move, I'm joining Meta as a software engineer on the Python Language Foundation team. In any case, I'm not disappearing from the open-source Python community. I'll be seeing you online and maybe even in person at Python-related conferences.

Applications to Join the PSF Meetup Pro Network Are Back Open

Following the introduction of the PSF Community Partner Program, the Python Software Foundation (PSF) is pleased to announce that we have reopened the application for Python Meetup groups to join the PSF’s Meetup Pro Network! We’re very excited to bring back this offering to the Python community after applications were temporarily suspended under the broader PSF Grants Program pause last August. Make sure to check out the PSF’s Meetup Pro Network documentation page for more information on how to apply. 

Reopening applications for the PSF’s Meetup Pro Network is a small but meaningful step forward for our community support-focused programs. The rest of the PSF Grants Program remains on hold while we work through important considerations, such as what we can responsibly budget and how the program will be structured for long-term sustainability. We look forward to sharing more updates when possible. 

The PSF welcomes your comments, feedback, and suggestions regarding the reopening of the PSF Meetup Pro Network on the corresponding Discuss thread. We also invite you to join our upcoming PSF Board or Grants Program Office Hour sessions to talk with the PSF Board and Staff synchronously. If you wish to send your feedback privately, please email grants@python.org. 

About the PSF’s Meetup Pro Network

The PSF manages a Meetup Pro account and adds qualified Python-focused Meetup groups to the overarching PSF Meetup Pro Network. Meetup organizers no longer pay for Meetup subscriptions once they become part of the PSF’s network. We currently have 109 groups in the PSF Meetup Pro Network, which costs the PSF $15/month per group.

The PSF can run reports on Meetup activity, such as the number of interested attendees and events. Management of membership and events is left to the group’s organizers. Any registration fees or deposits for RSVPing or paying for registration to an event are also managed solely by the Meetup organizer. 

Once a Meetup organizer accepts the invite to join, a notation will be shown under the group name: “Part of Python Software Foundation Meetup Pro Network.” Check out the Meetup Pro overview page for more information.

Criteria and how to apply

We've made the application process and criteria as simple as possible, so Python Meetup groups around the world can easily get the support they need. Along those lines, we’ve kept the requirements short and sweet—to qualify for the PSF’s Meetup Pro Network, a Meetup group must:

• Offer content that is majority Python related
• Include or link to a Code of Conduct in the About section of the Meetup page
• Hold at least 2 events per year (virtual or in-person)

To apply, fill out the short application form on psfmember.org, that asks for basic contact information, as well as gathers information related to the criteria listed above. Make sure you have an account on psfmember.org and that you’re signed in! A PSF Staff member will reach out with any questions or provide the steps needed to add eligible groups to the PSF Meetup Pro Network.
