When the eMudhra Intermediate CA was compromised, the #Python ecosystem had to move fast.

Within two days, fixes shipped for certifi, Python, pip, uv, sigstore, virtualenv, conda & more, with PyPI and python.org patched as well.

Read how PSF #security staffing made the difference, and what’s next:

A paper in Nature presents a new method for detecting exoplanets that is up to 15 times more sensitive than traditional exoplanet imaging methods. The technique uses a machine learning algorithm to remove starlight from telescope observations. go.nature.com/3X7k7T2 #AI 🔭🧪

We’re excited to welcome Joshua Mcshannon as the PSF’s newest Infrastructure Engineer! Joshua will help support python.org, @pypi.org, and @pycon.us infrastructure and add much-needed on-call redundancy.

Say hello when you see him in the repos 🐍👋

Very proud of our team with two papers on arXiv! Shrish Ray's does JWST wavefront sensing with a differentiable optical model (arxiv.org/abs/2610.40187), and Milo Langker's shows that you can infer a spectrum from a single diffraction-limited image (arxiv.org/abs/2610.41092)!
Spectral Information Content of Diffraction-Limited Images
High-resolution optical imaging is fundamentally limited by diffraction, which imprints wavelength-dependent structure onto the point spread function (PSF) of the optical system. This intrinsic chroma...

Joshua Mcshannon Joins the PSF as Infrastructure Engineer
The Python Software Foundation (PSF) is excited to announce our newest staff member and Infrastructure Engineer, Joshua Mcshannon, reporting to Director of Engineering Jacob Coffee. Joshua brings over 16 years of technical expertise from various backgrounds including bootstrapped startups and big tech. Most recently he built an AI-integrated learning platform for cybersecurity students and taught secure web application development along with DevOps/platform engineering. Joshua will focus on reducing operational complexity and toil of the PSF infrastructure, optimizing to better serve the community at large and internal PSF platforms that CPython core developers and staff members rely on daily; this includes services like python.org, PyPI, and infrastructure behind PyCon US. With Joshua on the team, the PSF will gain much needed redundancy for on-call rotations as well as capacity for new infrastructure projects. **_“We put people on the moon with a Ti-82, I’m sure we can figure something out.”_** Joshua has already shown great initiative in the work that the PSF has, diving deep into our Kubernetes infrastructure and preparing improvements to keep costs low. Away from the keyboard you’ll find him at a local show, on a nature trail, or at a flea market with his family. Say hello when you see Joshua in the repos, issue trackers, mailing lists, and on discuss.python.org! ## About the Python Software Foundation The Python Software Foundation (PSF) is a non-profit whose mission is to promote, protect, and advance the Python programming language, and to support and facilitate the growth of a diverse and international community of Python programmers.

There is apparently a FAKE conference called "PyConf 2026" that claims to be in San Francisco in December. I recommend that you do NOT register for this. The PSF is investigating.

I tried to contact them and the email bounced. If you're actually a representative of this conference please DM me.
