Open Source

Documentation is incredibly important for open source projects to communicate their value and show users how to make the most of their tools. However, it’s one of those things that often gets de-prioritized with all of the other work that needs to happen in a project.

We were excited to hear that JupyterCon is happening again in 2025. The Call for Proposals just wrapped up, and our team was involved in preparing and submitting several directly from 2i2c as well as from the ecosystem in general.

When we first committed to offer Jetstream2 support at 2i2c, Jetstream2, Magnum, OpenStack, ClusterAPI were all new concepts that we hadn’t used at 2i2c before. And although the initial exercise of reading about each of them independently was confusing, learning how they actually glued together was the key.

Thank you to Emilio Mayorga for sharing this publication. Several community members, including Paige Martin (Australian Climate Simulator), Eli Holmes (NOAA Fisheries), and Emilio Mayorga (University of Washington) published case studies in Oceanography magazine’s “Vision for Capacity Sharing” issue.

We are proud to announce that 2i2c’s Executive Director, Chris Holdgraf, was recently elected to Jupyter’s Executive Council. The 2i2c team discussed whether Chris should run for this position last year, and concluded that it was a way for our non-profit to both support Jupyter’s mission at a strategic level, and represent the interests of research and education communities in Jupyter’s direction.

Building upon our previous work developing per-user storage quotas for our AWS infrastructure, we are pleased to announce that this feature is now available for GCP-hosted hubs! To provide this feature on this vendor, we have updated our infrastructure provisioning system to create persistent disks, and enable automatic backups of the disk for disaster recovery purposes.

Project Pythia and the “Jupyter notebook obsolescence” problem # Project Pythia provides educational resources for essential software tools that enable open, reproducible and scalable geoscience, such as the Pangeo stack of packages (Xarray, Dask, Jupyter).

2i2c are pleased to announce the development and deployment of automated backups of home directories on GCP-hosted hubs! We have developed the gcp-filestore-backups project that regularly creates backups of JupyterHub home directories for disaster recovery purposes.
