@notabenemovies.bsky.social une inspiration pour le passage sous la maison, peut-être ?

We deleted a year of AI context files—and our evals got better. On The AI Native Dev podcast, I share what changed as Datadog scaled AI coding tools to 1,000+ engineers. tessl.co/sb6 #AIagents #DevEx

Node.js 26.4.0 is out with package map support! Full changelog and download links available at nodejs.org/en/blog/rele...

Experimental package map support has been merged ! Now on to implement generation support into both Yarn and pnpm 🚀

I'll be at #jsnation EU in Amsterdam on June 11 to talk about @yarnpkg.dev's Rust rewrite! Met amazing people every year, will anyone be there as well? @acemarke.dev @danielroe.dev @tkdodo.eu @nicr.dev maybe?

We just released the 4.15 branch 🎊 One important change is that npmMinimalAgeGate will now default to 1d for new projects.

Making `npmMinimalAgeGate: 1d` the default github.com/yarnpkg/berr...

Let me tell you, "sustainability in OSS" is going to become a matter of mental health rather than money more than ever before. I fear the field will get toxic pretty fast as projects start competing entirely on social marketing antics 🫤

Reminder that Yarn lets you filter out fresh packages with `npmMinimalAgeGate` and it's a good idea to use it on your work repos!

I'll be speaking at #JSNation to tell you the story of how we ported Yarn to Rust over the past year, and what we learned doing that (A LOT 😁) Check out my #JSNation badge: gitnation.com/badges/jsnat.... Register via the badge and watch the stream for FREE! See you on June 11 & 15.

We just released the 4.14 branch! 🎊 Two important security changes: - `enableScripts` now defaults to `false` (can be overridden on a per-package basis) - A new `approvedGitRepositories` setting should be used to tell Yarn which git repos are safe to pack.

I'm working on a feature called package maps for Node.js - it's leveraging everything I learned about package resolution these past six years, in a design that's both simple and flexible enough to be backward compatible with existing installs. I'm very excited about this! github.com/nodejs/node/...

It should go without saying: Yarn isn't and will never be a company. My vision of sustainable OSS has always been that not only should the tool be free, but its maintainers as well.

Perhaps a silly question - are multi-tenancy OSes legacy at this point? It feels like every machine nowadays only ever use a single user (perhaps a second for root). As far as I understand it even cloud deployments went away from unix's multi-user towards virtualization.

I'm implementing task management primitives into Yarn. I think tools like Turbo having to parse the lockfile is sign enough that they should be native features. Scripts have always been too limiting for local development.

The state of GitHub's "Require status checks to pass before merging" section is incredible. Never saw what should be such a simple feature that simply couldn't work in two different companies. I get 500s just by searching for my jobs !

I can now say it: Rust is really neat. I'm still on my learning journey, but I like many of its constructs. And I'm in love with pattern matching.

Noticed the amazing website? It's built with @astro.build from the ground up thanks to the help of the fine folks at luckymedia.dev, and the GLSL mad skills of shadertoy.com/user/Kali 😊

It’s happening. Yarn 6 Preview is here 💫 Yes, we rewrote it in Rust 🦀⚡️ I'm incredibly excited for the future of our beloved package manager. See the benchmarks and plans in our latest post:

Just left the theater - I found Zootopia a little lacking execution-wise, but overall I liked the universe enough that I could get past that and have a good time

I joined a middle school that turned out to have a programming club (ie 2-3 pro-linux kids self-learning Dark Basic on the school computers during lunch break).

I just realized it's the 10-years anniversary of my Secret Santa planner! I hope you'll find it useful this year as well 🎄☃️ mael.dev/secretsanta/

I am looking for a full-time job. Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me. If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂

I started a new position at Mistral AI this week, still focused on developer experience. Interesting change of pace, going from a huge IPO'd company to a super fast growing startup on the rise! And a European one at that 🇪🇺🥳

It's baffling that GitHub still doesn't implement a neutral exit code. It used to be there! It was inherited from Azure Pipelines and they just ... removed it, with no replacement.

Is that a surprise? The same can happen by having the LLM update the eslint configuration to add a malicious plugin. Due to how vscode works it'll be instantly evaluated.

Ruby Central said some really concerning things today. I don’t think they’re representing the situation accurately. andre.arko.net/2025/10/09/t...

An unfortunate oversight

Yarn 4.10 is fresh off the press! 💫 It includes a new npmMinimalAgeGate setting, catalog support, and OIDC publishing.

A good security aspect of my job lately has been that I spend significantly more time writing package managers than installing packages 😄

Can’t wait for this to land: drafts.csswg.org/mediaqueries... (API for recording user preferences in a way that just works)

Why is there no JS API that can flip prefers-color-scheme for the current page? Dark mode switches require adding custom selectors, which doesn't compose with third-party components.

Mistral is very good at building interesting narratives; much better than ChatGPT it feels: chat.mistral.ai/chat/5110f7a...

React 19 broke "click a component to open its source"; not sure the team is even aware? 😮 github.com/facebook/rea...

The more I see async iterators, the more I feel like they're a really fancy way to make a frustrating and painful API

I've been hoping for this proposal for so long ❤️ github.com/tc39/proposa...
