Chris update for July 2025: towards community-led funding proposals Hey all - here’s another quick update on what stood out to me from the executive council and the jupyter foundation. I think the theme for July was “ok, maybe we are all getting into too many details...

Here's an update from my perspective on the Jupyter EC for July!

discourse.jupyter.org/t/chris-upda...

- We're working on a public funding proposal process for the foundation
- The EC is trying to get better at actually delegating
- JupyterCon 2025 had a lot of submissions for its CfP!

A unicorn company that came from the hard work and creative thinking of a team of people sounds pretty great. A unicorn company built alone by a single person whirring a small army of LLMs in data centers feels...so much less exciting and fun.

I knew social media was still good for something 😅

Yes, if you make RTD versions track branches and not tags...

Note that you can now rename versions, so all you need would he a 1.x branch, and call it v1 on RTD

Amazing 😍

In ReadTheDocs is it possible to set a `latest/` for a major version, but have multiple major versions supported? E.g.

- `mydocs/v1` would update when 1.2.1 is released, then again when 1.2.2 is released, but not when 2.0.1 is released.
- `mydocs/v2` would update when 2.0.1 is released

Gave the repo2docker docs some love this week, I hope they're much easier to navigate and discover now!

Has anybody written up an analysis about how much energy the open source community uses in its CI/CD pipelines? And how much energy savings we could have with various optimization strategies?

I am really glad I did not read Station Eleven before the pandemic. Also wow what a book.

In your 20s, party start/stop times have a 2-hour buffer because your friends are totally unreliable.

In your early 30s, this shrinks to 30 minutes because people are functioning adults.

By your late 30s, you're back to a 2-hour buffer because everybody has kids and is totally unreliable again.

I'm excited about the latest release of the MyST Engine, because it means you can now host MyST sites and Jupyter Books on ReadTheDocs!

I couldn't help myself. I said no more public speaking this year but ended up submitting a talk to JupyterCon anyway!

You should submit one too! :)

god damnit the @github.com command palette was by-far the most useful way for me to navigate projects inside GitHub and now they're deprecating it 😭

🚨JupyterCon CfP extended to July 20th!🚨

This is in-part to give folks at SciPy some breathing room (the CfP was closing on the last day of SciPy before...sorry about that!)

A big opportunity and challenge at @2i2c.org is solving shared problems across our network of communities. It's hard to strike the balance between solving one community's problem, vs. solving that problem for everyone. Here are a few things we've learned:

Jupyter Book at the Scientific Python 2025 Developer Summit - Jupyter Book: Blog Updates from the Jupyter Book subproject.

A bunch of the Jupyter Book team was at the Scientific Python developer meetup in Seattle last month. We wrote up a little retrospective about it! It's exciting to see folks in the SciPy community excited about our new documentation engine!

+1 this is so damn cool

A Jupyter Book team goal over the past months has been improving the documentation for users and contributors in the @mystmd.org project. I wanted to share two important pages with big updates!

Haha fair. I guess the way I think about it is that we live in a moment where, for the first time in all of human history, we can instantaneously collaborate, create, and chaotically fight with everyone on the planet. Of course crazy+stressful stuff will happen! But it's impressive just to consider!

I think I'm giving off the wrong impression with my use of the word "drama". I don't think it is a totally negative word. Families are dramatic. Drama can be interesting! (And stressful lol)

No just the general vibes I hear about in the rumor mill. But I think this could probably apply to almost any big open source project haha

Since having two daughters I have completely lost the ability to keep it together during any video that involves dads and girls. I'm sitting here weeping to overly dramatic commercials selling Google AI products.
