Emma

I was a guest on the @realpython.com podcast to talk about #security and #Python 🐍🛡️ Thanks @digiglean.bsky.social for having me on the show! realpython.com/podcasts/rpp... (recorded before cybersecurity awareness month hit its full stride this week…)

Leaving the Python Core Dev Sprint feeling so energized. It’s this crew that has me coming back to the project time and time again. I love Python, Python is forever!

Apparently for today's cert leak the private key was the number 4

THIS IS NOT A DRILL. If you package/distribute/maintain root stores or chain verifiers, act immediately. If you know how to remove trust in a root, consider doing it now. Otherwise, prepare to update systems as patches/mitigations come. Go users, update to Go 1.27.3 or Go 1.26.10.

Update everything that verifies certificates against public roots.

If you’re using rustls, upgrade to rustls-webpki 0.103.16 and/or webpki-roots or webpki-root-certs 1.0.10.

** Speaker announcement ** The first speaker of RustWeek 2027 is Esteban Kuber, member of the Rust Compiler Team, with 'Building Rust for Humans'! Info & Tickets: 2027.rustweek.org/talks/esteban/ PS Want to join Esteban in our line-up? The CfP is still open! #rustlang #RustWeek2027

It’s Core Dev Sprint week, y’all! ❤️

I gave a talk at EMF titled "Men in Tech #YesAllMen", in which I told my experience of being a woman in tech. I was afraid to publish it in case it affected my current or future employment. With all the current news I would like to add my 2¢. So here is the recording: youtu.be/WXL6K1lhvt0?...

I just optimized PyFloat_PackN() C functions in Python using __builtin_bswapN() to swap bytes. Problem: GCC does crash and clang miscompiles the 16-bit function which uses _Float16 on IBM s390x! GCC bug report: bugzilla.redhat.com/show_bug.cgi... clang bug report: github.com/llvm/llvm-pr...

Two weeks until Python 3.15.0 final! hugovk.dev/next-release/ #Python #python315

The lovely folks from @rust-lang.org pinged me in a mutual security discussion channels about these ongoing attacks: There's no reason attackers wouldn't do the same to maintainers of Python projects. Report weirdness to security@python.org so we can alert others if needed. #python #security

⚠️ We believe that there is an ongoing campaign targeting owners of popular crates and rust-lang team members that is attempting to compromise devices and accounts in order to use them to publish malware. See our blog post for details: blog.rust-lang.org/2026/09/17/t...

if you wanna be a good trans ally, hire us to good jobs we are way more likely to face financial insecurity, make 60 cents on the dollar compared to our cis counterparts, and a lot of us are *insanely* talented

Unfortunately a job offer I had fell through due to head count elimination so I am currently on the market for a new job! If you need someone with 11+ years of Rust, backend, and distributed systems experience I am your guy. Contact Email: michael@ductile.systems. Boosting appreciated!

HEY did you know i made a giant starter pack of trans and trans-inclusive comic creatives? get followin'!

#PSF board election is now open (also for the Packaging Council), if you have affirmed to vote (or have done it last year), you have got the ballot (from OpaVote Voting Link) in your email inbox. Don't let it just sit there. #Python #election

As a new Harry Potter trailer makes the rounds, it bears repeating that there’s no way to watch this show without supporting J.K. Rowling’s bigotry and the structural violence she’s inflicting on the trans community.

Maintain an open source project? YOU can help test the next release of Python. It is really helpful to catch bugs and other issues before we release!

Had a lot of fun yesterday at Berkeley's first ever Frog Fest! 🐸 Loved the frog-themed activities, frog art, and got to see an albino frog!

Podcast interview with Deb Nicholson at PyCon Korea!🎙️ We talked about what @python.org does, her work as the PSF Executive Director, and her thoughts on supporting and funding the broader Python ecosystem. www.youtube.com/watch?v=l_cZ...

RustNL's Rust Maintainer Team has grown and now consists of 14 people, including three interns! ✨️ rustnl.org/maintainers/ Together, these people are either the author or a reviewer of more than 30% of all pull requests on the rust-lang/rust repository:

More good news: Jess Izen is stepping into an Engineer in Residence role with the Rust Foundation! She's done so much good work for the ecosystem already (see the post!) and I can't think of a better person to wear this hat 🦀 rustfoundation.org/media/welcom...
