Jupyter Open Studio Day SF 2025

The fun did not stop after JupyterCon. Next Monday after the conference, Bloomberg invited everyone to their office to collaborate on Jupyter projects. There were many of the friendly faces who decided to make a trek from Southern California to the Bay while there were here for JupyterCon.

Building on the momentum from the Sprint Day, I continued to explore those topics during the event.

• I exported all GitHub PRs and issues related to the filebrowser package (label:pkg:filebrowser) and ran analysis with Claude to find which of 800+ items might relevant to upload/copy/move UX. As a good first issue to solve (I’ve never contributed to the JupyterLab core!) I prototyped the button to cancel the file upload in JupyterLab. Below is my feature in action, but the full presentation is available here.

• I had a chat with participants about how my Jupyter Marketplace can be useful for developers, what additional signals to include. I appreciated a suggestion from Ely @ Bloomberg to include a contribution activity indicator (number of commits/issues/PRs over some period of time).
• I had an opportunity to help Hannah Chen @ Bloomberg to try and set up my Auto Dashboards extension for generating Streamlit dashboards from Jupyter notebooks with live preview inside JupyterLab. She is uv user, so I learned how to do a development install using uv for JupyterLab extensions and updated my instructions.

Huge thanks to Ely and Bloomberg for the invite and organizing the event for us!
