Why does 2i2c upgrade core infrastructure quickly when new versions come out? Our collaborators at NASA VEDA recently asked us this exact question. Here's how Yuvi explained it. 👉 2i2c.org/blog/why-upg...

This is a nice little vignette that shows the value of having a devops team continuously developing and upgrading your deployment - updating more often when it's not *required* means doing less work when you *have* to upgrade.

Love this vision of "Backseat software". We need more software that's useful on its own right, and doesn't constantly try to inject itself into your life. blog.mikeswanson.com/backseat-sof...

I'm really excited to see 2i2c leaning more into open product development practices by building a public roadmap. This is a way for us to find more common ground between the needs of our member communities, and opportunities to support open source.

We’re proud to share a public roadmap for 2i2c's team - it's a step toward more participatory, transparent open development with our member and upstream communities. 👉 2i2c.org/blog/public-...

It's been so cool seeing new contributions in jupyterhub from @jnywong.github.io . She's brought a creative and collaborative spirit that I really appreciate! Congrats on joining the team!

We’re incredibly proud to announce that Jenny Wong was invited to join the JupyterHub team as a contributor and maintainer! 2i2c.org/blog/jenny-j...

Check out Angus' talk about the Jupyter Book re-write, and the new MyST Document Engine! Thanks for repping the jupyter book project at FOSDEM, Angus!

This was an exciting round of UX improvements to nbgitpuller thanks to feedback from the team at UC Berkeley. Thanks to the CloudBank team and @ucbids.bsky.social for facilitating collaborations like this!

🛳️ New release of myst-theme ! This is a patch release to fix a bunch of UI/UX bugs that we uncovered after the last minor release. Thanks to everybody for testing and quick feedback! github.com/jupyter-book...

This was an interesting experiment in using JupyterHub to deploy a *data science design* environment, for a user workshop, rather than a typical "notebook analytics" environment. You can serve all kinds of interfaces and side-applications with JupyterHub!

Another release of Jupyter Book and the MyST document stack! Thanks to everybody for all of the testing, bug reports, and bug fixes :-) it gets better each month :-D

We're proud to announce a new release of the Jupyter Book stack! This brings in a number of fixes and UI improvements! Check out release notes for each here: mystmd 1.8: github.com/jupyter-book... myst-theme 1.1: github.com/jupyter-book... jupyter-book 2.1.1: github.com/jupyter-book...

I'm proud that 2i2c is able to make space for more people to participate in open source leadership and community building in this way! Jupyter is lucky to have April helping out :-) 2i2c.org/blog/april-j...

I find this kind of thing really exciting - 2i2c is basically a centralized shared infrastructure team, running independent community hubs, in a way where we can directly give others control over their own infrastructure in a safe way.

We improved jupyterhub-home-nfs so that admins can see per-user home directory usage within minutes and get quota limits as metrics, so it’s easier to spot disk usage problems early. 2i2c.org/blog/faster-...

2025 had a lot of learning for us - in part, we learned that it is really hard to balance both a shared infrastructure platform *and* a collaborative development service! Here are a few thoughts about the tension between these, and our plan to leaning into that tension in 2026.

"Who is using the most resources?" is a common question for cloud admins. With our new user group cost dashboards, you can answer that question with more granularity! 2i2c.org/blog/2025/cl...

We recently pushed Jupyter Book 2, which was a breaking change for many of our users! We considered publishing a completely different package (e.g., `jupyter-book2`) but decided against it. Here's a quick rationale why:

This is a pattern I'm excited to lean into - many communities get opportunities to use cloud resources ad-hoc. We'd like our membership to be an easy way to quickly get resources when you need them, when credits / access / etc is available by government/state resources.

I'm really excited to welcome BIDS as our founding premier member organization for 2i2c. It has been one a key strategic partner ever since our creation and I look forward to many more years of impact!

Brett Cannon has a fascinating blog post about how community-wide enhancements take a *lot* of slow, methodical, diligent work behind the scenes. This kind of thing is so under-appreciated and so important chrisholdgraf.com/blog/2025/lo...

Interested in a sustainable future for open source communities in research and education? @kirstiejane.bsky.social @ucbids.bsky.social are hosting @2i2c.org leads @choldgraf.com and Yuvi Panda, w/ Jarrod Millman at the AI Futrues Lab-supported by UC Investments: events.berkeley.edu/BIDS/event/3...

It's really exciting to see Min back on the BIDS team. He's been a huge leader and contributor in open source over the years, and I'm excited to be able to work with him more closely in his new timezone and role! bids.berkeley.edu/news/min-rag...

I'm really excited to announce the first partner in our new membership model for @2i2c.org - BIDS has been a huge ally over the years and I'm excited to keep improving open infrastructure together with them

📣 Thurs, Oct 16 @ 3:30pm PT -> Launching the BIDS membership of @2i2c.org ! With special guests @choldgraf.com and Yuvi from 2i2c - Help shape the future of open source at UC Berkeley at a fireside chat, a Q&A session, and community gathering time with snacks and drinks! 🍿🥤

We've learned that our member communities care a *lot* about cloud cost transparency and reliability, so we're working hard to drill down into user data about costs and usage for community leaders to access.

This post describes the system we're piloting to provide team-wide contributions to open source projects that are strategic and impactful ✨. It's a follow-up to 2i2c.org/blog/2025/go..., which described our goals in being a Good Upstream Citizen for 2i2c.

How should organizations support open source communities? We're moving from scattered individual efforts to strategic team-based contributions that strengthen upstream communities like JupyterHub 🚀 👉 2i2c.org/blog/2025/fo...

Million dollar idea: A bot that joins every of your Slack/Zoom/Meet videos for the first 3 minutes and debugs everybody's microphone and video problems immediately.

🚨 The deadline for Jupyter Community Funding Proposals (blog.jupyter.org/your-ideas-o...) has been extended to October 5th, 2025 ( by one week). We've got a few great-looking proposals in the works (github.com/orgs/jupyter...), so you've all got another 7 days to write!

One of our team goals last quarter was improving "demonstrable reliability" of our infrastructure - we've learned that making the cloud safe, predictable, and reliable is a key thing our member communities need to make the most use of their hubs

Would love feedback from anybody that follows along with this post series - doing leadership in open source often feels like invisible work, so this is one attempt at making is a bit more visible!

I really want somebody to re-write nbviewer so that it uses mystmd.org under the hood for sharing galleries of notebook content!

TIL the Jupyter Community Forum at discourse.jupyter.org gets like 600,000 user visits a month!

We reduced AWS infrastructure costs for communities by switching from older `r5.xlarge` to newer `r8i-flex.large` instances for our "always-on" hub infrastructure. It's a good day when we save cloud costs for our communities ✨ Learn more 👉 2i2c.org/blog/2025/aw...

LLMs can be a useful partner in conversation, but don't forget they are also sycophantic and reluctant to challenge you. Apparently this is leading to relationship breakups because their LLMs convince people they're utterly in the right. futurism.com/chatgpt-marr...

Do I have any colleagues that would let me borrow their apartment in NYC the weekend of October 8th? :-)

TIL you can get web analytics plots for GitHub dashboards. Insights -> Traffic

If you aggregate the unique weekly visitors from jupyter.org, docs.jupyter.org, and mybinder.org, and multiply that by 52 weeks, you get about *16 million unique visitors to Jupyter websites each year*. Wild. Check it out 👉 plausible.io/jupyter.org

JupyterCon 2025 has an early-bird registration discount that ends October 3rd! Get your tickets now, and check out the schedule below events.linuxfoundation.org/jupytercon/p...

We’ve extended the deadline for Jupyter Community Workshop proposals! Proposals are now due September 14th, and review will be complete by September 26th. Workshops will be held through February 2026. Learn more and submit your proposal here: blog.jupyter.org/jupyter-comm...

We are gonna have to get a lot better at writing quick n dirty blog posts! 😅

Open practices means open communication. We're running an experiment to share more of our learning, experiments, and contributions in real-time rather than waiting for polished outcomes. Here's a little post describing this effort 👉 2i2c.org/blog/2025/co...

Here's an update for the Jupyter Community about what stood out from my view on the Executive Council in August. tl;dr, we finally have a call for proposals for community funding! I suspect this will take most of time for the next month or two. discourse.jupyter.org/t/chris-upda...

Y'all set a very high bar in terms of the empathy you bring to your interactions with stakeholders (in the sense of being able to consider their viewpoint). The balance with "foundational contributions" really sets you apart in this ecosystem (and I'd hope gives you a "competitive edge"!)
