@cmaureir I am still processing all the #PyCon inputs. Thanks for your talk and for making C a little bit less intimidating. Looking forward to being able to add appendappendappend :)

my PyCon US talk is online! you can now listen to me spiel about attestations and PEP 740:

Welcome to another exciting edition of "Phildini Liveblogs Talks After They Happened", starting with @amethyst's #PyCon talk "Or Else!"

Last night I was talking to @leonardr about stories that are set so far in the future that they are functionally fantasy. "The Book of the New Sun", "The Dancers at the End of Time", that sort of thing.

This morning I was passing #Pittsburgh's Steel Tower, which is an ordinary office building that happens to be the tallest skyscraper in the city, on the way to #pycon sprints, and it occurred to me that The Steel Tower is totally the sort of thing that could show up in such a story.

PyCon was lots of fun! The slides for my talk on processing large JSON files without running out of memory:

Looking forward to videos getting posted so I can watch all the talks I ended up missing due to scheduling conflicts/practicing my talk/getting lost/meeting someone in the hallway.

Y'all shouldn't allow me to be stimulated by #Python, friends, & amazing talks for 3 days straight. It gets gears moving too much, and then I become an idea faerie, and nobody really likes those too much.

Anyway...

Why don't we see #art contests or galleries at #PyConUS (& other #PyCon conferences)?

There are SO MANY amazing #Artists in the #Python community, and a screen intended for slideshows (or even a poster) does not really give them an effective way to share what they've created.

1/5

What an unforgettable time at #PyConUS 2025!

We loved connecting with #PyLadies from around the world!

PyLadies Lunch
PyLadies Auction
@georgically announcing PyLadiesCon 2025
@mariatta Unveiling our new open-source project

So grateful to share this journey with you all!

Loved the keynote by @drkariljordan, Executive Director at @thecarpentries, today at #PyConUS! It was awesome to hear about the instructors and individuals that have made use of #Python to make an impact.

Some of the people called out directly include @aflaxman, @fgazzelloni, and @marijane (the others couldn't be located on Mastodon).

May as well throw this query out to the fediverse.

I am looking for *concrete examples* of code that works correctly when interpreted by Python 2.7 but *silently produces incorrect output* when interpreted by Python 3.x. I encountered such a thing about 10 years ago but didn't save it and have been unable to reconstruct it.

All examples are good, but examples that produce output from which it's difficult or impossible to recover the correct output are better.

My #PyConUS session is later today, let's find out together if your requirements.txt is haunted?

Join the haunt in Ballroom BC at 1:45PM, don't be scared!

Have you ever been annoyed by some Python code not stopping immediately when you press control-C? It's a common problem in scientific computing because of bugs in many of the compiled-code "extension modules" that accelerate this use of Python.

I gave a talk today at #PyCon about what needs to happen to get those bugs fixed. I'm told a video will be available within a few days, but already you can see my slides and detailed notes at <https://research.owlfolio.org/pubs/2025-pyext-ctrlc-talk/>.

After the t-strings open space today, a lot of people wondered how they could get in touch/stay up to date.

We just stood up a (very preliminary) website with links to resources and contact information. It'll expand greatly between now and when 3.14 launches.

https://t-strings.help/

I attest that this will be a good talk. Come verify!

Whoever created this, thank you. This captures the energy of open source perfectly. If you see a problem you can be the one to fix it, and that's amazing!

That was a fantastic keynote by @roguelynn today at #PyConUS about the necessity of play.

It really resonated with me (and I'm sure many others) having worked on and maintained many projects and faced burnout. It brought back memories of an open space that occurred at PyCon US 2021 where this issue was brought up and heavily discussed.

At #PyConUS and wondering what to do after the plenary sessions? Interested in #opensource #security?

Dustin Ingram and I are hosting a supply-chain security open space with many talks! Come hang out and meet fellow security-minded Pythonistas in Room 321 at 10:30:
