Overhauling repo2docker's documentation | 2i2c 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…

Documentation doesn't get enough love these days! We're heavy users of the repo2docker tool for user environment generation for our communities. Chris recently spent a bit of time updating repo2dockers documentation, and wrote up an experience report about it. Thanks Chris!

Product and team highlights from Q2 2025 | 2i2c This post highlights what stood out to us from last quarter and reflects on the targets we set at the start of the quarter. This quarter, our team learned the importance of shipping iteratively and…

Each quarter, our team checks in on what we've released, how we've improved as an organization, and what's coming next for members of our community network.

What we've been up to: 2i2c.org/blog/2025/q2...

Solving classes of problems, rather than just an instance of a problem (with an example) | 2i2c The Problem # Two of our the communities we serve ( NMFS Openscapes and CryoCloud) reported issues with starting GPU nodes on their hubs. Upon investigation, I discovered that the cluster autoscaler…

Our Product team gets a unique view across science and education communities. That perspective means we're able to solve classes of problems, in ways that benefit all the communities we serve.

Yuvi, our Tech Lead, shares what happened when we noticed autoscaling problems: 2i2c.org/blog/2025/au...

DevCon 2025: A DevOps and Cyberinfrastructure Success Story | CIROH DocuHub Our team demonstrated how modern DevOps principles and cloud infrastructure can seamlessly support large-scale technical workshops for over 200 attendees.

CIROH's Research Cyberinfrastructure and DevOps team shared their experience and methods from their recent DevCon - check it out for inspiration: docs.ciroh.org/blog/devcon2...

Congratulations to the team on a successful conference! It was a pleasure collaborating with you!

We're addressing feedback on the challenges of managing user groups in JupyterHub by introducing new group management features to track resource usage efficiently. By integrating insights from Prometheus and Grafana, communities can better manage complex, dynamic user bases: 2i2c.org/blog/2025/ju...

Offering Jetstream2-powered hub support at 2i2c | 2i2c 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…

Early this year, we started to explore Jetstream2 on behalf of our NSF-supported communities. We're happy to report that 2i2c is now able to deploy both mybinder.org-like hubs as well as persistent storage hubs on Jetstream2 hardware!

What we’re learning about cloud costs for Earth science workflows in our JupyterHub – Openscapes Andy Teucher

Openscapes, partnering with NASA, NOAA and 2i2c, hosted a community call in April 2025 to share learnings about managing cloud costs for earth sciences.

Check out the blog post, including the community call recording and notes:

Launching Jupyter Book for 2i2c Communities | 2i2c A core component of our mission to make research and education more impactful, accessible, and delightful is leveraging our unique global network of communities to make meaningful improvements to the…

We've launched Jupyter Book for 2i2c communities!

With Jupyter Book 2, communities can focus more on content than design, with improved interactive environment launches from Jupyter Book, added features for landing pages, and colocated community documentation with hubs.

Volume 38 Issue 1 | Oceanography Volume 38 | Number 1 | March 2025

Three of our user communities put 2i2c infrastructure to work making research and education more accessible, and they shared their experiences in the March 2025 Oceanography magazine: tos.org/oceanography....

Chris is joining Project Jupyter's Executive Council | 2i2c 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…

We're proud to announce that our Executive Director, Chris Holdgraf, was elected to the Jupyter Project's Executive Council! We excited for the impact that he'll have in this strategic role!

Towards frictionless, portable, and sustainable reproducibility with Binder | 2i2c Last December I had an opportunity to discuss the current and future state of the open publishing ecosystem at a workshop hosted by HHMI1. While 2i2c doesn’t primarily focus on “publishing”…

We're exploring ways to support scientific reproducibility and sustainability with Binder. What if we could reduce the gap between where researchers conduct their computational analyses using open source technologies and bridge them to publishing platforms for dissemination?

Thank you for letting us know @antonakhmerov.org ! We've popped the full link above in the replies.

2i2c joins the mybinder.org federation with a cheaper and faster way to deploy Binderhub | 2i2c If you’re interested in supporting mybinder.org with cloud resources, financial resources, or human resources, please see the Support Binder page for how you can help. tl;dr: The 2i2c team is joining ...

Whoops the link got cut off! Here is the full link to the blog post: 2i2c.org/blog/2025/bi...

2i2c has officially become part of the mybinder.org federation, introducing a new, cost-effective, and faster approach. We hope to make it easier for more people to join the federation by contributing a single-node BinderHub at 2i2c.mybinder.org.

Enforcing per-user storage quotas with `jupyterhub-home-nfs` | 2i2c When sharing a storage disk between users, as is usually the case in a JupyterHub deployment, it is important to put in guardrails so that one user cannot eat up the whole storage capacity from the…

We have just shipped a solution for managing storage quotas in JupyterHub with @developmentseed.org 🚀

No more worrying about users filling up shared storage space. Check out our blog post for more: https://2i2c.org/blog/2025/per-user-storage-quota/

2024 impact report: new team structure, new funding, and growth in our network | 2i2c 2024 has been a busy year for 2i2c, with many highs and lows, a lot of impact, and significant organizational change. As the year comes to an end, I want to reflect on the work we’ve done in 2024, and...

As 2024 draws to an end, we’re excited to share our retrospective and impact report. We’re incredibly proud of the work that 2i2c and our community network have done in 2024, and would love to hear your feedback for where should go next in 2025. : 2i2c.org/blog/2024/re...
