Purpose

Think of it as a monthly, virtual JupyterCon. It’s a place to announce and share fun things happening in the Jupyter community.

For more discussion on the format of these calls, see the thread here.

Short reports, celebrations, shout-outs

This is a place to make community announcements (without a need for discussion).

• The Jupyter Book community have submitted a paper describing Jupyter Book 2 and MyST to the Scientific Python proceedings

  • It’s still in PR form but ready for you to read: Jupyter Book 2 and the MyST Document Stack

  • This was a huge amount of work and a wonderfully inclusive effort!

  • We’re particularly proud of the case studies from The Turing Way, QuantEcon, Project Pythia, and the QIIME 2 Framework (Q2F) documentation ecosystem :rocket: :star2:

• The Jupyter Book community also merged some updates to our documentation, including a pronunciation guide for MyST!

• GeoJupyter hosted a really successful hackathon in Berkeley in August

  • There were 4 teams that organically emerged:

    • infrastructure developers exploring containers and development environment setup,

    • documentation specialists filling in gaps and testing tutorials with fresh eyes,

    • API developers working on Python integration and data manipulation workflows, and

    • strategists zooming out to question JupyterGIS’ fundamental purpose.

  • Read the blog post to find out more! https://geojupyter.org/blog/20250903-inperson-hackathon-and-design-dialog/index.html

• JupyterGIS was used as a supporting visualisation for a Nature article!
