The stable release of Python 3.14 is out now! Go, go, go update! 🙌

discuss.python.org/t/python-3-1...
Cute illustrated logo featuring a pink/peach colored pie displaying ‘3.14’ (pi), surrounded by two snakes in blue and yellow. The design is encircled by text reading ‘r-strings • zsid • free-threading • support • sub-interpreters • REPL highlighting • note colour • colour’ in a circular arrangement. The illustration uses a soft pastel color palette with blue, yellow, and pink tones, and includes decorative sparkle elements.

The High-Energy Physics Advisory Panel (HEPAP), which I served on a few years ago has been dissolved.
The six DOE Office of Science FACA (Federal Advisory Committee Act) committees are now replaced with the Office of Science Advisory Committee (SCAC).

Already understaffed and now further diminished, the Cybersecurity and Infrastructure Security Agency is scrambling to investigate a spate of cyber attacks. The lapse of the Cybersecurity Information Sharing Act has made it even harder.

Federal officer blasts chemical spray into vocal but nonviolent Portland protester, video shows

The interaction illustrates how federal law enforcement officers do use aggressive tactics against protesters who yell and needle officers but don’t appear to present clear physical threats.

Governor JB Pritzker @govpritzker.illinois.gov · 4d
This morning, the Trump Administration’s Department of War gave me an ultimatum: call up your troops, or we will. It is absolutely outrageous and un-American to demand a Governor send military troops within our own borders and against our will.

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.

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.

(Telling you things that you already know given your background). Most clusters are not HPC systems where you have modules or are busting out Spack to do machine specific HPC builds of software. I will read your linked blog post (thanks) but having bespoke control over your software feels normal.

Wait how is this a question at all? Why are people not just using conda-forge for everything unless they need bioconda? What is there to actually discuss? Unless you had a service level agreement with Anaconda, Inc. to begin with (in which case this is a non-issue) why would you _want_ to use it?

So again, my question is “I’m not an R user and I care about this stuff for all other forms of scientific computing. The R community does science and doesn’t have good binary support for Linux. That seems strange from the outside. Why is that?”.

Matthew Feickert @matthewfeickert.com · Aug 16
Unless you’re using Spack & doing _real_ HPC workloads, ad hoc source installs are not going to cut it for my requirements. You need multi-platform securely built binaries with inspection of the build chain and provenance. You don’t get this out of the box (without help from Posit) for Linux R pkgs.

You’re probably scientists or researchers (in transit and didn’t check your profiles) so I’m not saying that you’re “bad” for disagreeing. I’m saying that as scientists we should care _a lot_ about our computational environments and be able to trivially know they are reproducible to the byte level.

“being a Linux user is a life of needing to know how stuff work”

Being a _scientist_ is a life of needing to know how stuff works.

Linux is the only choice (for now) for problems that need computing that is any of following: hardware accelerated, large scale, distributed, large data, cloud, etc.

Coming back to this a month later as I was on social media hiatus to teach. Again with real questions, not digs. Your comments seem like you don’t know or care(?) what software is running your code and how it got there. If true, how do you view your relationship between science and software?
