Well, time to start setting up shop for real away from Twitter - used to be fperez_org there, used it a lot as a science feed and community building tool, til the Musk purchase. Went quiet since but hadn't fully moved on; the election seems like a good time to shut the curtains and move.

Join us for the next #OSPO Meetup “Open source AI models” cohosted by @d-lab-uc-berkeley.bsky.social, featuring @fernandoperez.org & Cathryn Carson! They'll discuss open source AI, sovereign implementations, data privacy, & more. Thurs, Oct 15 @ 3pm PT in person & online Register ➡️ bit.ly/4hQ1Al9

We are excited to welcome @fernandoperez.org, creator of IPython and co-founder of Project Jupyter, to open Compute! Paris with a keynote on “Jupyter, open source and AI: science and humans?”

Are you interested in building open tools for biomedical science in the @jupyter.org ecosystem? Infrastructure, front end, AI workflows, product design - we are recruiting for multiple positions at @ucbids.bsky.social and would love to hear from you! bids.berkeley.edu/news/join-us...

Cheers to @uofcalifornia.bsky.social Berkeley News for this great write-up on the benefits of #OpenSourceAI models, featuring Schmidt DSE faculty advisor @cboettig.bsky.social and faculty co-director @fernandoperez.org. Read & share: news.berkeley.edu/2026/08/11/w... #OpenSource #OpenScience

Friends! I'm bad at advertising but better late than never! I'm co-organizing a workshop at #CSCW2026 exploring the future of infrastructure, in conversation with its deep roots in CSCW scholarship. Please join us! cscw2026-infrastructure-workshop.github.io My short pitch below 👇

🌟 📚 Join BIDS at the annual National Workshop for Data Science Education, June 22-24! Our panel on June 23 will feature #Jupyter ecosystem topics #JupyterBook, #GeoJupyter, #JupyterAI It's free to attend in person or on Zoom! Hope to see you there ➡️ cdss.berkeley.edu/dsus/nwdse

Congrats to @serenabonaretti.bsky.social or the physical publication of her awesome "Learn Python with Jupyter" 📙 👏 🎉 , and thanks for sending me a physical copy to Berkeley! The weaving of Python+Jupyter and how to use them to think is wonderful. We're fortunate to have Serena in our community!

📣 A great postdoc opportunity to work with @tsnow03.bsky.social at the intersection of statistics, earth science and open science! book.cryointhecloud.com/postdoc

Today, we’re launching Lightcone Research. AI is changing what’s tractable in scientific research, putting more ambitious questions within reach. We build open-source infra that turn this expanded reach into results other scientists can reproduce, inspect, and build on.

If you work in open source software, particularly in the life sciences, the new @os4science.org Fund is launching its inaugural call for proposals!! A great opportunity with a broad perspective on what can be funded.

📣 New #OpenSource fund for #science! Building on the impact of EOSS led by @dartar.bsky.social , this new @renphil21.bsky.social program will help scientific communities continue building our computational foundations as an open, public good. os4science.org/news/os4scie...

Last call, today at 11am, Evans Hall at UC Berkeley and online! Come for a talk and discussion by the amazing @gaelvaroquaux.bsky.social on scikit-learn, open science and an open discussion in today's science and AI context, hosted by @ucbids.bsky.social and Berkeley Statistics!

Do you have any thoughts on systemic bottlenecks in science and how to fix them? Astera is running an essay competition! astera.org/essay-compet...

UCS filed Freedom of Information Act requests to the NSF to publicly release all of its communications about its plans to restructure the National Center for Atmospheric Research (NCAR). “NCAR represents one of the most successful models of federally supported scientific infrastructure in the US.”

"Cementing a machine-learning ecosystem: scikit-learn and beyond": on Friday March 20, we at @ucbids.bsky.social and the Berkeley Statistics department are delighted to host @gaelvaroquaux.bsky.social for a seminar. Join us in person or online! events.berkeley.edu/BIDS/event/3...

🎊 We are proud to share our 2025 Annual Report, a celebration of our collaborators, alumni, and supporters + BIDS impact: bids.berkeley.edu/annual-repor... @fernandoperez.org #OpenSource

It's an honor to work with the @ucbids.bsky.social team, part of our new @berkeleycdss.bsky.social college! While "Data Science" may now be a well established idea, there is still much work to do, and Berkeley is a unique environment for this!

Interested in open science across disciplines, but especially in earth/climate/environmental tools, workflows and communities? Join us -live/zoom! @ucbids.bsky.social OSPO event, hosted at AI Futures Lab, for a discussion with NASA scientist Tasha Snow. events.berkeley.edu/BIDS/event/3...

On a busy day for science policy, it looks like oversight and operations of NCAR’s supercomputing center are transitioning to a third-party operator. www.nsf.gov/news/transit... Lean more about the costs of dismantling NCAR with this opinion from @carlonimbus.bsky.social.

📢 Call for Papers | Special Issue in Remote Sensing of Environment We are excited to announce a forthcoming special issue in Remote Sensing of Environment focused on the rapidly evolving area of Geospatial Foundation Models and their transformative potential for environmental remote sensing.

Adding an `anywidget` style/based directive & renderer into the core @mystmd.org stack is a big win for custom interactivity and extensibility. My contribution this week: to round off the first cut implementation - based on what've had in prod at @curvenote.com. opensci.dev/articles/ups...

UC Berkeley's DataHub team shared error log data that helped us redesign error handling in nbgitpuller - a tool used across education and research to distribute Jupyter content via a single link. 2i2c.org/blog/nbgitpu...

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!

What Americans Lose If Their National Center for Atmospheric Research Is Dismantled - Eos | Five ways dismantling NCAR will cost the American people, and two ways to save it.

Opinion: For more than 6 decades, NCAR has shown that open, collaborative science can save lives, support economic resilience and national defense, and expand opportunity across generations. #SaveNCAR

The power of open! Awesome to see this, which builds on the open source work done at @ucbids.bsky.social years ago by @mentat.za.net and Nathaniel Smith: bids.github.io/colormap/ Nathaniel wrote up a bit more about this work in his blog: vorpus.org/blog/the-unr...

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...

NCAR represents what is possible when a nation chooses to invest in science as a public good, writes @carlonimbus.bsky.social of @ucs.org. #SaveNCAR eos.org/opinions/wha...

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...

France announced today it’s phasing out Teams, Zoom, etc. to be replaced with a French/European solution called Visio. The data is hosted on Outscale. Transcripts and subtitles are also handled by French providers. The target is set on 2027 for government agencies.
