I noticed today that PyPI now (not sure for how long) has a filtering option when you look at the distributions of packages. That's a nice quality of life improvement.

The Data Science Institute is assuming responsibility for a new, campus-wide effort—the RISE-AI Collaboration HQ—which will catalyze research communities centered on innovative focus areas and build connections among @uwmadison.bsky.social's AI community. news.wisc.edu/rise-ai-coll...

Many well earned congratulations to Lukas! Quite a big deal and fully deserving as it matches his vision for the future of particle physics. Very much looking forward to seeing where he leads his group in discovery!

Big grant news today! I feel very lucky and honored for this opportunity from @erc.europa.eu . We will attempt to go for a big qualitative step up in how we use AI/ML to predict how particles interact with matter. Stoked to get started on this in 2026. we will release job advertisements soon!

1/New paper led by Matthias Vigl arxiv.org/abs/2509.01397 - we wanted to see whether you can see double descent and a benefit of overparametrization in particle physics data and tasks. We see both model- and epoch-wise double descent but the story is more complicated than we thought:

Personal opinion: GitLab as a company is bad at interacting with community and it shows.

This is absurd. The red supergiant Betelgeuse is the bright feature in this image. But that darker blue splotch is a *companion star* that's just been discovered—and it orbits so close to Betelgeuse that it's inside the larger star's outer atmosphere.

Thank you @prefix.dev and Astral (tagging @crmarsh.com as the company isn't on Bluesky AFAIK) for bringing these tools to scientists everywhere far faster than I expected! Also thanks to @snarky.ca and everyone else who thought, worked, and pushed hard to get standards and people moving.

lol. Listening to a data science podcast and people are discussing distributed model training using “this software called SLURM”. University computational research pays dividends yet again.

Today I learned that Michigan is on Eastern time and not Central and oh boy does that change up some scheduling for the week in interesting ways.

I've now fully gotten rid of pyenv from my Python development life with Pixi and uv! Feels pretty great to have a much cleaner workflow _everywhere_.

🎉 Great news: Our Machine Learning and Physical Sciences workshop will be back again this year! 🎉 Keep an eye out for updates on deadlines etc, we will be updating the website soon ml4physicalsciences.github.io #ML4PS2025

Learning in action at #SciPy2025! 👀 Yesterday’s #Pixi workshop showed how to mix conda + pip, simplify ML, and speed up training. Thanks to @matthewfeickert.com, Ruben Arts & John Kirkham! We’re back this morning with our packaging workshop. Come demystify #Python! lnkd.in/eBk5cz6i

Seeing fellow organizing committee member Paul Anzel on my flight makes it feel like #SciPy2025 started early for me. :) Very excited for this week!

Have seen zero news about how the BBB lets ACA premium subsidies expire at the end of 2025. The high deductible bronze plan for me and my son would be $1350 a month without those subsidies (it’s $176 month now). An increase of $14,089 per year. I think people will forgo health insurance.

The Big Beautiful Bill has important new limits on graduate student and professional school student loans from the US government—of particular importance at law schools, a $50K per year borrowing limit (w/$200k cap), starting in the summer of 2026. The key text is in the screenshots below.

America is beautiful, contradictory, unfinished. I am proud of our country even as we constantly strive to make it better, to protect and deepen our democracy, to fulfill its promise for each and every person who calls it home. Happy Independence Day. No Kings in America.

Happy #HiggspendenceDay to everyone! It has truly been an amazing period of knowledge growth since the discovery announcement. :)

I don’t think anyone is prepared for what they just did w/ ICE. This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined. It is setting up to make what’s happening now look like child’s play. And people are disappearing.

I'm really looking forward to getting to teach this tutorial with @ruben-arts.bsky.social and John next week at #SciPy2025! This has been fun to collaborate with them on to create. I hope tutorial participants enjoy it and come away feeling they have a whole new toolkit to empower themselves with!

🙌 We’re excited to have @matthewfeickert.com, John Kirkham, and Ruben Arts teaching us "Reproducible Machine Learning Workflows for Scientists with pixi" at #SciPy2025! 🔥 Learn how to create fast and reproducible ML environments using pixi, the next-gen package manager for scientific workflows.

I'm hiring! Looking for folks interested in a postdoc position on muon colliders, spanning accelerator and experiment. More info here: fa-ewlq-saasfaprod1.fa.ocs.oraclecloud.com/hcmUI/Candid... @muoncollider.bsky.social

A student doing work this shoddy for a class presentation would fail. Shouldn't the standards be even higher for people making decisions about the health of all Americans?

Catastrophic.

NEW: NSF will be kicked out of their building. Announcement will be made tomorrow by HUD Sec. and Governor of VA. HUD will take over the NSF building over the next two years. NSF staffer: "There is no planning for NSF, no identified future location, appropriation for a new building or a move."

The United States should not wage war against Iran. Donald Trump’s bombing of Iran is unconstitutional. Only Congress can declare war — and the Senate must vote immediately to prevent an another endless war. This is a horrific war of choice.

🔥 Meet our Keynote Speakers for #SciPy2025! Dr. Yusra AlSayyad is Deputy Associate Director of Data Management at the Vera C. Rubin Observatory and a researcher at Princeton University. 👀 Don’t miss her talk on lessons from a decade of scientific Python in astronomy ➡️ hubs.la/Q03sdlsb0

Michael Pham fled Vietnam at the age of 13. He was named bishop of San Diego a month ago. Today, he stood watch at a courthouse: ICE agents were “standing there covered with masks as we walked toward the courtroom. Eventually the agents scattered and went away” timesofsandiego.com/life/2025/06...

Power is out, which means it is a “work from cafe” day.

🔥 Meet our Keynote Speakers for #SciPy2025! Dr Malvika Sharan, co-Director of Open Life Science (OLS) and a senior researcher at The Alan Turing Institute will be sharing with us her expertise at our favorite conference. You can't miss her ➡️ hubs.la/Q03sdlsb0

I suspect that fact that the vast majority of LLM users don’t seem to have received this (really very simple!) message is because the AI companies have a vested interest in us not understanding it. “ChatGPT is smart, it just makes mistakes sometimes” is much more marketable than the truth.

🔥 Meet our Keynote Speakers for #SciPy2025! Hon. Dr. Kathryn D. Huff 🇺🇸, nuclear engineer, policy leader, and former Assistant Secretary for the Office of Nuclear Energy will be joining us in Tacoma! 🙌 Don't miss her talk, grab your ticket now: hubs.la/Q03sdlsb0

PHOTOS: Thousands protest in ‘No Kings’ rally in Urbana

@msnbc.com reporter at the 1:15 mark. “The chaos you’re seeing is not the result of peaceful protestors, it’s the result of actions of law enforcement, specifically the Los Angeles sheriff’s department.” #nokings

Millions of people marched. Millions. We hear that number a lot, even billion, so it doesn't sound as big as it should. That's a *lot* of people. Do you know, say, 100 people? A million is ten thousand times that many. Want to count to a million one per second? It'll take 11 days. A lot of people.

Just finished up at the Evanston No Kings rally. It was safe, peaceful, and a show of solidarity by *at least* 1,000 people. Go to your local protest. Don’t let this administration scare you. Stand with your community when our leaders won’t.

Shortly after the Atlanta #nokings event kicked off at 10, organizers said Liberty Plaza near the state Capitol had already reached maximum capacity of 5,000.

As AWS open source just turned our request down, anyone have contacts at Google Cloud or Microsoft Azure who thinks they might be interested in donating cloud credits for an educational tutorial at SciPy 2025?

Journalists and others, take note: this is an excellent, comprehensive, and up-to-date perspective on the still-escalating threats to NOAA beyond the NWS. NWS remains in pretty dire straits, yet the prospects for the rest of NOAA are actually even more dire (especially with respect to climate).

If I were asked to teach physics with ChatGPT I would honestly seek a job at another institution

This is a BSG quote I've thought about a lot in recent years, as French law enforcement has become increasingly militarized, and I found myself and my son gassed during a completely peaceful and quiet protest (for a social subject).

When reviewing resumes it becomes difficult for the nerd in me to not fixate briefly on the myriad of kerning crimes that appear upon opening some files.

More NSF news: here's a letter from 89 former members of the 12 dissolved advisory committees to the NSF, House, Senate, and NSB. drive.google.com/file/d/1N44A...

I've seen folks talk about how "in four years" they'll be able to get back to their planned projects and I really don't think that's going to work out. People & projects losing funding now will not be able to hit pause and come back once funding is restored. Hard-won progress & capacity will be lost

Joint w/@asinclair.bsky.social and the #SCIMaP team: brief correspondence in @nathumbehav.nature.com on the impact of NIH indirect cost cuts on the economy and employment, impacts that will only worsen given similar proposals for NSF/DOE + overall science proposal. rdcu.be/eo3Hp
