Feels very surreal but this is a general PSA that you should go and chase your dreams/aspirations. Even if they feel scary. Even if they feel too big.

Do it, scared ✨

I'm assuming we are all going to be Charlie XCX fans by the time you are done with the "and now for something completely different" section of the release notes.

Graphic with yellow background, Gleam's mascot and headline "Stack Overflow Developer Survey 2025: Most desired languages". Below that there's a screenshot from the survey: "Programming, scripting, and markup languages Rust is yet again the most admired programming language (72%), followed by Gleam (70%), Elixir (66%) and Zig (64%). Gleam is a new addition to the list, and for good reason - developers like it!"

2025 SO Developer Survey results are out and... wow! Gleam is the second most desired language. It's the first time we appeared in the survey and it's an unexpected result!
Being listed next to
@rust-lang.org @elixirlang.bsky.social & @ziglang.bsky.social makes us proud! Thanks, everyone who voted!

Notebook users: what are your favourite and least favourite things about the execution paradigm of Notebooks?

I’m interested in hearing about kernel mgmt, compute selection, venvs, etc

I didn't announce anything in my keynote, it just acts as a warning message that I can be a bit tenacious and thus somewhat exhausting for the gatekeepers I have to convince that I'm proposing something reasonable.

You did attend my EuroPython keynote, so you know what this could mean for you

Is there going to be an RM tattoo?

Watch out: my next big project is now possibly going to involve you if I don't get it done fast enough to be @hugovk.dev 's problem 😁

I didn't say the cars were stupid and dangerous, just that I can't accept that the text specified in the image is legitimate without backing evidence these days.

If the entire internet goes up behind paywalls because AI kills the ad market, what will those AI models have to train against?

Notice the subtle "made using AI" watermark on the right-hand side.

This is why I no longer believe anything posted on social media that doesn't link back to the source and that source must be reliable.

But guess who suffers first when you use AI as a search engine? Those reliable sources.

It's succinct because I found I glossed over it too much to actually drive a change in habits for myself.

Actually spotted mine!

Screenshot of my initial terminal launch showing how I point out `ls` is really `lsd` and that autojump is installed.

I'm glad I'm not the only person who does this!

I was explaining to my Ukrainian colleague the phrase ‘There’s no such thing as a free lunch’. She told me the equivalent in Ukrainian is ‘The only free cheese is in the mousetrap’ - which is so much better

Twice as many people are killed by cows in the UK per year than are killed by sharks in Australia.

I gave a talk at @europython.eu about “Exploring the CPython JIT” where I go to a journey in the execution pipeline, from the Python source code to native machine code.

fstrings.wtf - Python F-String Quiz Test your knowledge of Python's f-string formatting with this interactive quiz. How well do you know Python's string formatting quirks?

I got 21/26 on @mitsuhiko.at's fstrings.wtf quiz.

I spent a lot of time creating a cheat sheet and article on f-strings, so I was kicking myself after a few of them that I should have known. There were definitely a couple surprise Python features for me though!

Brett Cannon on Python, humans... and packaging Also, I asked about rewriting CPython in Rust just in case

This is my favorite BiteCode podcast episode so far.

It's deeply human, touching, taking us from a floppy in Amsterdam to the entire internet, and even Mars.

It's a pleasure to share our chat with Brett Cannon, Python core dev and self-proclaimed snarky Canadian:

Yeah, that's one of uv's unfortunate deviations from the pip UI (and which was an overall concern from the pip team at the start of uv because of this sort of confusion would occur)
