We recently figured out a simple way to give individual users their own /tmp folder so that they have more space in a cost-effective way. /tmp is often used for storing intermediate data files and processing steps, but a few communities like MAAP and EarthScope were running into size limits.

This summer, we participated in the Responsible GenAI for NASA Earthdata workshop, a community gathering organized by University of Washington’s eScience institute, to explore how others were using GenAI in their workflows across the NASA community, and share best practices.

I recently got back from the 2026 Responsible GenAI for NASA EarthData workshop in Seattle. It was an opportunity for members across the NASA ecosystem to share their experiences experimenting and learning with Generative AI models around Earth Data.

Compute quotas and usage dashboards are now available on 2i2c hubs 🚀 This allows hub admins to cap the amount of compute resource a user can access over a given time period, as well as providing end-users with updates on their current usage.

What we learned # Migrating from one ingress controller to another is not a trivial task! Context # The news that the best-effort maintenance of the Ingress NGINX Controller would end in the first quarter of 2026 sparked a considerable amount of discussion among the community about what the best replacement for this controller is.

At the 2026 Pythia Cookoff at NCAR, we spent some hackathon time rebuilding the Project Pythia Cookbook Gallery and blog on shared MyST Engine tooling, replacing the one-off custom scripts Pythia had been using before.

Starting with Dask Gateway version v2026.3.0, JupyterHub access scopes support has been added to Dask-Gateway. That means hub admins can now set, via JupyterHub role-based access control (RBAC), which hub users or groups have access to Dask-Gateway.

We helped shepherd and implement a batch of accessibility improvements in myst-theme as part of the Jupyter Book project. The Jupyter Book team blogged about it here: jupyterbook.org/blog/posts/2026/accessibility-improvements Accessibility is a key part of making technology broadly impactful and useful, and it’s increasingly a requirement for the institutions we serve.

This week, another Linux kernel exploit “Dirty Frag” (CVE-2026-43284 and CVE-2026-43500) was disclosed to the general public. Unlike the recent Copy Fail Linux kernel zero-day, this set of exploits was leaked ahead of the embargo period expiring, leaving insufficient time for kernel maintainers to release a patch.

Eric Van Dusen was running a workshop titled “Teaching in the AI Classroom: Expanding Access to Interactive Computing through JupyterHub and CloudBank” at the National Artificial Intelligence Research Resource (NAIRR) Annual Meeting, showing how JupyterHub can be used to seamlessly provide access to GPU computation for teaching.
