If you work on tools that deal with source maps, TC39-TG4 (the source maps working group) has a hackathon in Amsterdam on 18th May 2026 at the JetBrains office. @nicr.dev is the organizer who can be reached via BSky DMs or Matrix if you wish to register.

Waiting for midnight hoping that in April Renfe will release their full June timetable. I feel like a child waiting for Santa 🎁

Thanks to @wooorm.com I learned that I can change the text selection color in MacOS and now I can make everything pink.

I hate it so much when I have to book a train trip that has multiple trains, and the first one sells out before that the timetable for the last one is even available.

This is the user: github.com/dfzysmy2tf-c... They are opening issues in tens of repositories, and none of those are security vulnerabilities (in most case, the behavior they are describing is not even what actually happens!) If you see an issue from them in your project, go ahead and block.

There is a GitHub user (LLM?) that is reporting a lot of "security vulnerabilities" as open issues. They are mostly trash reports (e.g. "if you pass Object.prototype to the setFooOnObject function, it will set Object.prototype.foo so that's prototype pollution"), but what if one is real?

This is SO funny It's a parody of the Italian government websites, and it feels exactly like the originals pucs.it

Cool! Apparently the npm Dependency Links VSCode extension has a configuration to specify a custom registry. Now ctrl clicking a dependency in package.json takes me directly to npmx.dev. { "npmDependencyLinks.registryUrlPattern": "https://npmx.dev/package/{{pkg}}" }

We have more than 80 people registered to participate onsite in the Web Engines Hackfest 2026: webengineshackfest.org#attendees If you want to join us, please fill the form at: forms.gle/7gSwfFebFW7s...

I'm seeing this sudden drop in download counts in most popular npm packages, happening in the last 3 weeks. Does anybody know what's going on?

How do we get to more than just three web engines owned by three US companies? It's a gargantuan question, with no easy or right answer. I've put together a draft report, thinking about it through a very specific approach - please enjoy: Servo Readiness Report webtransitions.org/servo-readin...

Last week we were able to present @robpalmer.bsky.social with his physical Ecma Recognition Award! 🎉 This was followed by an extensive round of tributes and praise, which Rob endured somewhat uncomfortably, at every opportunity urging us to cease and attend to the waiting celebratory Temporal cake.

Remember Flow? flow.org Facebook just open source their port to Rust 👀 github.com/facebook/flo...

Prikkert.nl/en should work for this! If not I'd like to know where to improve :)

Does anybody have any recommendation for an open source tool to schedule a meeting, that: - supports time zones (so no framadate.org) - works when scheduling past a DST change (so timeful.app) (Maybe one that uses Temporal? 👀)

I am very excited to announce our partnership @eurosky.social with @igalia.com! The partnership will accelerate the development of independent, European-operated infrastructure for the open social web, enabling developers, organizations, & communities to build new applications. cc @xanlopez.xyz

Very much rooting for Cloudflare here

So do you like more the AI-generated videos with baby cats going through a difficult life, or the ones where Ms. Broccoli cheats on Mr. Tomato with Mr. Cucumber but in the end they become gay for each other?

ECMAScript Excitement 🎉 This week, TC39 elected a new editor group for the ECMAScript specification (ECMA-262). Editors are: ✨ Linus Groh ✨ Michael Ficarra ✨ Nicolò Ribaudo (@nicr.dev) ✨ Richard Gibson ✨ Ron Buckton (@chronicles.org) ✨ Shu-yu Guo (@rfrn.org)

RFC 3217 — The internet is for everyone "By 2047 the world's population may reach about 11 billion. If only 25% of the then world's population is on the Internet, that will be nearly 3 billion users."

So nice when you are in a station in the Netherlands and your favourite restaurant (the German ICE) unexpectedly shows up thanks to a delay.

@bkardell.com and @meyerweb.com chat with Igalia's @ptomato.name, @nicr.dev and Bloomberg's @jason-williams.co.uk about the JavaScript Temporal API www.igalia.com/chats/tempor...

Temporal is now Stage 4 at TC39 🎂🎂🎂 Thanks to all the other champions of JavaScript's new date-time API. It has been a wild ride over many years! I wrote a blog post explaining how we got here 📜 bloomberg.github.io/js-blog/post...

Polypane is really cool

ECMAScript EXTRA-SPECIAL excitement 😉 🚨🚨🚨 IT'S ABOUT TIME! 🚨🚨🚨 Congrats to @ptomato.name on advancing Temporal to Stage 4 at @tc39.es today 🎉 Temporal is the replacement for the JavaScript Date API 👍

Exciting things happening in TC39 right now

Apparently I sponsor @patak.cat on GitHub, @patak.cat sponsors @danielroe.dev, and @danielroe.dev sponsors both @patak.cat and me. I feel like there is an optimization opportunity here 🤔

JavaScript quiz: what is the output of this code? (code in the alt text for copy&pasting)

Emptying the Nutella jar and then putting it back in the cabinet making me believe I can have some must be a crime.

🚀 We've released Moonforge, a brand new fully open-source Linux distribution based on Yocto. We aim to provide a production-ready foundation for building embedded operating systems! Read more: www.igalia.com/2026/03/09/I...

Some time ago, @jonkuperman.com & @tchetwin.bsky.social had a dream for the JS engineers at Bloomberg to be more public about the cool JS work we have going on. That dream has come true - now we have a blog platform 🎉 (You'll see more articles over the next few days) bloomberg.github.io/js-blog/

Step 1. Get hired by Discord Step 2. Implement background updates for their desktop app rather than forcing me to update when I want to open it Step 3. Quit Discord

Updating my Ubuntu version feels scarier than migrating across PDSes.

Atproto Amsterdam happened! We solved private data AND payments, and also digital credentials trust chains and also moderation and games too. Wait, no we just had a great three hours of chatting about atproto (mostly). Thanks @internetarchive.eu for hosting us!

So unfair when your good quality bug report gets closed as a duplicate of one opened 10 days later 😭

npmx is now in alpha: this is our story, as told by our team and friends

We need a shared database where we can mark GitHub accounts as "LLM pretending to be a human", and an extension to surface that information. Similar to how Bluesky labelers work.

JavaScript's date object has been tricky for years, but that is changing. The NEW Temporal API brings, 🌍 Easily handle time zones 📆 Precise date math 🕒 Parse ISO strings without errors ⌛ Durations, date ranges, and more. Start experimenting 👇 developer.mozilla.org/en-US/docs/...

Revolut lets me add drawings on my card, and in the "Transportation" category it has everything except for trains???

We are having a small atproto meetup in Amsterdam this Thursday! As it's the first time there is limited space: sign up if you want to come :)

The cake I made yesterday for my boyfriend's birthday

The EU is working in a revision of air passenger rights. It does some good things (like requiring airlines to process claims more quickly), but it also increases the minimum delay to be eligible for compensation for 2h to 4h. There is an EU petition asking to restore the original minimum time.

After seeing @lcas.dev trying to deal with a domain renewal on Squarespace for three days... Folks, that's all rotten. Jump off to literally any other registrar. You probably have domains there after that Google Domains shut down a while ago: move them to somebody that knows how to handle domains.

atproto fact: the @npmx.dev PDS is only 3 hours by train from the @eurosky.social PDS. We're lucky to have powerful friends so close to us. Germany is slowly becoming the European atproto data pole.

I am so confused. Why does the first one work and the other two don't? www.typescriptlang.org/play/?ssl=3&...

The EU Commission published a new regulation on Open Railway Data 😄 eur-lex.europa.eu/legal-conten...

Does anybody know based on what GitHub generates "invoices" vs "receipts" for payments? It seems to be entirely dependent on which cart I use to pay, but I do not understand *what* in my cards makes it do one thing or the other.

@thealexlichter.com given that you liked my last two posts, we are on the same PDS, and we are in the same city, what about having dinner some day next week? :) Are there other npmx-adjacent people in Amsterdam? 😄 @matteogabriele.bsky.social?

Who do we need to lobby to to make @github.com add a "Post on Bluesky" button here?

I will be so sad the day Claude stops hallucinating my name as the author of all these cool JS projects.
