2i2c at JupyterCon 2025: Helping communities navigate the Interactive Computing ecosystem

Thu, 20 Nov 2025 00:00:00 +0000

This year several team members attended JupyterCon 2025 to show off our own work and the upstream work that we’ve been doing in open source. JupyterCon recently shared the videos of all talks, so here’s a quick run-down of 2i2c’s contributions and where you can watch more.

Building computational narratives with Jupyter Book #

Introducing Jupyter Book 2: Next-generation Tools for Creating Computational Narratives - Chris Holdgraf and Rowan Cockett ( Curvenote) introduce the next generation of Jupyter Book, built on modern tooling and designed for creating rich computational narratives.

Tutorial: Build-a-Jupyter Book With the Turing Way - Angus Hollands co-led this hands-on tutorial teaching participants how to create their own Jupyter Books using examples from the Turing Way.

JupyterHub’s evolution and sustainable operations #

Not Just for Notebooks: JupyterHub in 2025 - Yuvi Panda explores how JupyterHub is evolving beyond just notebooks to support a wider range of interactive computing workflows.

Cloudy With a Chance of Savings: Per-User Usage and Cost Monitoring for JupyterHubs in the Cloud - Jenny Wong presents our recent work improving tools and approaches for monitoring per-user cloud costs in JupyterHub deployments, helping communities operate more sustainably.

Lightning Talk: Controlling Home Directory Costs (with User Empathy) on the Cloud - Yuvi Panda shares practical strategies for managing home directory storage costs while keeping user experience in mind, using jupyterhub-home-nfs.

Finally, there were also several talks that weren’t by 2i2c team members, but were partially enabled by 2i2c’s collaboration. We’re particularly proud of these, because it’s an example of us bringing others into the ecosystem and empowering them to contribute.

Understanding the JupyterHub community #

Findings from the Voices of JupyterHub report - This community strategy talk shares insights from conversations with JupyterHub users and operators about their needs and challenges. It’s not given by a 2i2c team member, but many of us have been involved in guiding (and being participants in!) this project.

MyST-ifying Project Pythia - Julia Kent of NSF NCAR discusses Project Pythia, an open-source platform dedicated to educating geoscientists on Python for complex Earth data analysis. Learn how Project Pythia manages its expansive repository of “cookbooks” and educational content, detailing their strategic shift to MyST Markdown and Jupyter Book 2 to drastically improve project sustainability and reduce maintenance overhead.

How CryoCloud built a healthy open science community #

Building a successful open science community in the cloud - Tasha Snow shares key insights from running the CryoCloud JupyterHub, emphasizing that a successful scientific community relies on both technology and social innovation. She shares data-driven results on how shared JupyterHubs can significantly reduce research computing costs and accelerate scientific iteration. She also explores the critical balance between platform capabilities and the need for social infrastructure to overcome technical barriers and foster true collaboration.

Sharing JupyterHub's vision for more flexible application deployment at the doepy talk series.

Wed, 03 Sep 2025 00:00:00 +0000

Our Technical Lead Yuvi Panda recently gave a talk at the doepy meetup about JupyterHub’s interest in moving beyond the “single-user notebook application” and towards a more flexible approach to enabling administrators to deploy many different types of applications and environments.

Check out a video of the talk here:

This is an important step for the JupyterHub project in order to support the many different kinds of workflows that data scientists need to use in their work. We hope that this generates more interest in the JupyterHub project and gives us useful feedback to guide the team’s understanding of this direction.

An update to 2i2c's value proposition

Mon, 06 May 2024 00:00:00 +0000

2i2c recently finished it’s three year retrospective after closing out its original seed grant. As part of this process, we’re revisiting our organizational strategy, structure, and overall plan, in order to incorporate the learning that we’ve done over our first three years.

Our value proposition is a key framing for 2i2c’s intended impact, key stakeholders, and platform strategy. We recently completed a team exercise to refine this statement for 2i2c, and are excited to share it with you below:

A global network of community hubs for interactive learning and discovery

Our interactive computing platform gives your community a digital home to create and share knowledge, and a global network of communities to learn from.

This is an exciting direction that leans into and builds upon the way we’ve described our service so far. It recognizes that the value in our service doesn’t end with simple access to an interactive computing environment, but lies in how that environment’s tools empower a community to create and share knowledge with one another.

We believe that this is an exciting direction to build towards, because it is based in the value of the collection of communities we serve, and the way that this network can be greater than the sum of its parts. We’re excited to lean into this direction in how we shape our platform, what open source contributions we make, and where we aim to have impact in the coming years.

To begin, we’ve interwoven some ideas from this value proposition into 2i2c.org, and the way that we describe our service. We’d love feedback from anyone who has an idea, a critique, or “yes, and” to share.

A recent talk with this value proposition #

As part of this work, 2i2c’s Executive Director, Chris Holdgraf, gave a talk about 2i2c to the Incentivizing Open and Collaborative Research (ICOR) community. Here are some links in case others are interested:
