Good omen! Got upgraded to first on my flight to #PyConUS!! 💅

I am *so* excited to see all my friends this week at #PyConUS!

maybe a good time to update your workflows to *not* use pull_request_target with a checkout securitylab.github.com/resources/gi...

oh my god

doesjitgobrrr.com now shows annotations for merged PRs to JIT-related files and other infra changes. This should help surface what might be contributing to day-over-day performance shifts! www.doesjitgobrrr.com?goals=5%2C10...

ah yes, i'm at the point in my talk writing process where i think it's absolute garbage. must mean i'm prepared enough.

Me before feature freeze yesterday? Pasting inline comment screenshots into general PR reviews.

Just as importantly! After two years, it's now time to ceremoniously hand over the `main` branch to @savannah.dev! `main` is now accepting new features for Python 3.16, and I bet it's going to be even better than 3.15. peps.python.org/pep-0826/ #Python #Python315 #Python316

Python 3.15 beta 1 is here 🎉! This means that 3.16 (my first release as RM) is in development! Not to be sappy but this is such an honour. The trust the team has in me is not lost on me. I will do my best to make sure that 3.16 is the best Python yet. 🖤 discuss.python.org/t/python-3-1...

i'm going to lose my mind. love to literally not be able to review PRs with less than 24 hours before beta 1

aaaaaa I have THREE talks next week at #PyConUS! you should come to all of them!! but if you want to listen to me wax poetic about containers and my favourite 3.14 feature, sys.remote_exec(), this is the talk for you!

I updated the #PyConUS feed to have the 2026 branding! Check it out and follow it since you can't follow hashtags by themselves!

finally finished migrating all my sites over to @fastapicloud.com but let's hear it one more time for my little rpi docker swarm cluster that hosted all my personal sites. rip arrakis 2024 - 2026 <3 savannah.dev/posts/raspbe...

Python 3.14.5 release candidate is out now! Please test! blog.python.org/2026/05/pyth... Next up, 3.15 beta 1 tomorrow. #Python #Python314 #Python315 #release

beta 1 go brrrrrr

PEP 831 (aka "frame pointers everywhere!") was accepted! If you are an author of a C extension or native lib built with a custom build system, it is now strongly recommended you add -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer to CFLAGS so profilers & debuggers can step through your lib.

in! space!

rather personal but it's our 1-year wedding anniversary this weekend (!!!) and apparently to celebrate we've been featured on the cover of a magazine???? lmao

📰 Core Dispatch #3 is out! It was a busy two weeks for PEPs, leading up to beta 1 next week. 5 PEPs accepted, 2 rejected, an early 3.14.5 to land the incremental GC revert, and 3.15 beta 1 next Tuesday! coredispatch.xyz/editions/3

ughhh github is about to become tech's next great schism, isn't it? counting down the days until half my watchlist packs it up for gitlab or tangled. mega bummer.

New machine on doesjitgobrrr.com today! We've now got a Linux aarch64 runner thanks to @diegor.it 🎉

What's that you say? The very first FastAPI Conf! ⚡ Coming at you live! This October! In Amsterdam! Y'all better get yourselves on the waitlist!

sorry, you mean to tell me that auto-save is not the default in vs code??? is everyone just manually saving files out there???

A massive congratulations to the @typescriptlang.org team on this release! We love to see it 🎉 Looking forward to migrating my projects over to 7.0 in the coming months!

Went to an early screening of Damian McCarthy’s Hokum tonight and holy hell, that was probably the scariest film I’ve watched in a long time.

artisanal kubernetes

As of yesterday's run, Python 3.15 with the JIT enabled made the FastAPI benchmark: - 1% faster on RPi (blueberry) - 2% faster on Windows (prometheus) - 6% faster on Ubuntu 24.04 (ripley) - 13% faster on macOS M3 Pro (jones) www.doesjitgobrrr.com/run/2026-04-18

lmao, make it stop.

A very busy week prepping this edition! 😅 Thank you to @hugovk.dev and @emmatyping.dev for helping curate and edit edition 2. 🖤

🗞️ We're going to revert the incremental garbage collector in Python 3.14 and 3.15. See here for details: discuss.python.org/t/reverting-... #Python #Python314 #Python315

An internal team just adopted tsgo (soon TypeScript 7) and told us they were able to shave off about 400 hours a month of waiting on CI builds. npmx.dev/package/@typ...

Just shipped v0.2.0 of the @fastapi.tiangolo.com VS Code extension! There's now a CodeLens above your path operations showing how many tests reference them, which you can click to jump straight to the test(s). Now you can navigate in both directions: path operation to test, test to path operation.

We were so lucky to have @lukasz.langa.pl as our very first Developer in Residence. I consider the program an incredible success story of what funding can do in open source. That is in large part a reflection of his hard work, and the amazing team of DiRs who followed. Thank you Łukasz!

Frame pointers? Frame pointers! peps.python.org/pep-0831/

Breakfast thoughts: are people still using jQuery anymore?

Y’all, I don’t even speak Spanish and will need to use Apple Live Translation via my AirPods, but you better believe I will be *seated* for my good friend @pablogsal.com’s keynote! 🔥

Folks, this next edition is going to be good. I'm already looking at the curated content and people have been working on very cool™️ stuff. Subscribe if you haven't already!

Just released debugwand v0.5.0, now with Podman support! Thanks @corona10.bsky.social! 🎉 pypi.org/project/debu...

lmao to the “recruiters” in my inbox offering me JavaScript roles. read the room, my guy, read the room.

Niche but since folks have asked: If you've noticed the prometheus runner (Windows) on doesjitgobrrr.com looking worse lately: tail calls were enabled since that's what shipped in 3.15.0a8, so it's an "interpreter got better" situation, not a JIT regression.

I panic-bought tickets to see Dune 3 in 70MM IMAX opening weekend at the Metreon, so I guess I’m going to SF in December!

Correction: April 7th is a TUESDAY! Releases on Tuesday! (We are now accepting editors 😅)

Core Dispatch #1 New releases are slated to drop on Monday: 3.13.13, 3.14.4, and 3.15.0a8. PEP 803 got accepted, so free-threaded builds will have a stable ABI. Ken Jin also wrote up what's going on with the JIT in 3.15. coredispatch.xyz/editions/1
