• SSC Representative Nominations.

  • Email sent this morning
  • Nominations are due Jan 29th, 2025.

• Andrii

  • [jupyter-collaboration] Issue #390 "notebook and lab can't open in RTC" - I can reliably and easily reproduce this problem by updating from jupyterlab-chat version that uses jupyter-collaboration v2 to one that uses jupyter-collaboration v3; .jupyter_ystore.db file is not getting moved / updated notebook and lab can't open in RTC jupyterlab/jupyter-collaboration#390 (comment)

    • (discussion from JupyterLab call)
      • David Q: We should explore dropping YStore by default.
      • We should open new issue for a) adding a configurable for enabling YStore & defaulting to False, and b) making YStore better. Instead of a document_ttl, we should probably just have max_updates. This bounds the disk use and makes disk use independent of when the updates were made.
    • [Zach here] my hunch is that this thin package might be a culprit. I'm not saying this package is a problem, but it's heavily under-tested. lihttps://github.com/davidbrochart/sqlite-anyio

  • [jupyter-collaboration] Issue #425 "Should most collaboration python packages depend on jupyterlab?" Are there any downsides to adding a JupyterLab dependency pin to jupyter-collaboration? A mechanism like this to specify which versions of JupyterLab current version of jupyter-collaboration is compatible with would help with versions mismatch issues. Should most collaboration python packages depend on jupyterlab? jupyterlab/jupyter-collaboration#425

    • From disucssion during JupyterLab call community seems okay with pinning, looking for more opinions if any, would be happy to open a PR

• Piyush

  • Is there a plan to move discussions to Zulip from Gitter?

• Jan-Hendrik, Sofus: Demo Blender+Jupyter: https://github.com/Octoframes/bpy_jupyter

  • Such a cool demo!
  • Flags for enabling Blender to connect an external kernel

    --ServerApp.allow_external_kernels=<Bool>
        Whether or not to allow external kernels, whose connection files are placed
        in external_connection_dir.
    --ServerApp.external_connection_dir=<Unicode>
        The directory to look at for external kernel connection files, if
        allow_external_kernels is True. Defaults to Jupyter
        runtime_dir/external_kernels. Make sure that this directory is not filled

Agenda

• Discussion around maintenance + dev challenges

  • Mike posted in Zulip that help is needed in JupyterLab for reviews, releases, etc. Link: https://jupyter.zulipchat.com/#narrow/channel/103349-ask-anything/topic/YOUR.20help.20needed.20-.20reviewing.20PRs.20.28frontends.29
  • Ian mentioned that this is needed across the board, in kernels, server, etc. If there are resources coming/available (maybe the EC can direct this), let's find a way to support our core projects.
  • Nick commented on how we test our software wholistically. After the "Big Split", this got a lot harder. How do you get the "right" eyes to review the PRs/issues that need review?

• Mike

  • new nbconvert release https://github.com/jupyter/nbconvert/releases/tag/v7.16.6
  • new jupyterlab releases
    • https://github.com/jupyterlab/jupyterlab/releases/tag/v4.3.5
    • https://github.com/jupyterlab/jupyterlab/releases/tag/v4.4.0a3
  • Add item count? added item_count jupyter_server#1492
  • GitHub Secure Open Source Program - call for maintainers to join (some training involved)
    • GitHub Secure Open Source Fund! jupyter/security#82
    • https://resources.github.com/github-secure-open-source-fund/
    • 3 week program: 5-10 hours of instruction
    • I do not understand what is the GH Sponsors situation
