I couldn't be at #guadec2026 this year but I recorded a talk about JavaScript in GNOME, static analysis, types, and some performance work that @igalia.com is supporting. Will we finally nail the Big Hammer?? Video: www.youtube.com/live/HnduDRy... Slides: ptomato.name/talks/guadec...

JavaScript's new Date-Time API was standardized two days ago 🎉 Here's an interview with @ptomato.name @jason-williams.co.uk & Andrew Paprocki on the creation of Temporal 📮 www.bloomberg.com/company/stor...

The Temporal proposal, co-championed by Igalia, advances to Stage 4 at TC39 — replacing JavaScript's Date API after nine years of work. Congratulations to everyone involved! Here's to better date-time handling on the web and beyond. www.igalia.com/2026/03/13/T...

It was a pleasure to be on our Igalia podcast once again, chatting about Temporal!

Temporal is finally here, "8 yrs, 11 mos" in the making! Congrats @ptomato.name and and the champions! Humbled to be invited to the @tc39.es meeting where it moved to Stage 4. During my work on temporal-polyfill, I collaborated with the champions to improve datetime arithmetics and duration rounding

ECMAScript Euphoria! 🎉 We don't always post when a single proposal advances, but when we do, it's Temporal -> Stage 4. Just days shy of 9 years from Stage 1, a herculean effort on the part of many champions, delegates, invited experts, and contributors, past and present. Thank you all! 🙌

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...

Some of my coworkers at @igalia.com worked on this feature!

Congratulations to @bkardell.com on joining the W3C TAG! www.igalia.com/2026/02/10/I...

Open source sustainability requires corporate action, not charity: Igalia engineer proposes concrete pledges to compensate unpaid maintainers

The EC is putting together an initiative to develop their strategy for open digital ecosystems. Given its potential to push forward the development and funding of open-source software in Europe and beyond, Igalia submitted a response with some suggestions. Read more: www.igalia.com/2026/02/03/I...

Wrote a blog post about the work I've been doing at @igalia.com to implement the Temporal proposal in JavaScriptCore: blogs.igalia.com/compilers/20...

ECMAScript excitement 😉 🚨🚨🚨 IT'S ABOUT TIME! 🚨🚨🚨 Congrats to @manishearth.bsky.social on shipping the Temporal API in Chrome 144 stable today 🎉 developer.chrome.com/blog/new-in-... Temporal is the replacement for the Date API.

Temporal_rs has been released!!! This is the first public release of Temporal_rs, a Rust implementation of the Temporal API powering Boa, Kiesel, V8 plus other engines. This will be shipping in Chromium soon More info in our blog post: boajs.dev/blog/2025/09...

GNOME 49 has been officially released! Head over to the release notes to discover all the new features and enhancements: release.gnome.org/49 Many thanks to our community for your work over the past 6 months. You're amazing! #GNOME #OpenSource #FLOSS #FOSS #Linux

www.youtube.com/live/Z7F3fgh... Should time jump to it

The livestream from my talk at #guadec2025 is up: www.youtube.com/watch?v=Z7F3... It'll be edited into individual talks later, but for now you can fast-forward to the second talk in the livestream. Slides: ptomato.name/talks/guadec...

I've been enjoying the talks at GUADEC 2025 and tomorrow I'll be on the stage myself, talking about what's new in JavaScript and TypeScript for GNOME development! (Sneak peek: in GNOME 49 we'll get Temporal 😄) Come see me live or follow along online at 10:10 CEST! events.gnome.org/event/259/co...

The recording of my talk about Temporal from JSNation last month is published! gitnation.com/contents/tem...

Ok, I've had whiskey and my flight is delayed, so... time for some unadvised unadulterated software eng and management advice (thread)

This is a good read on why monthly donations are more helpful for the GNOME Foundation than yearly or lump-sum donations. I've used GNOME for many years, and contributed to it for about half those years, and I'd love it if you'd like to join me there on the "Friends of GNOME" page

It has indeed been a difficult year for GNOME, financially. If you benefit from GNOME as a user, we really need your donation: donate.gnome.org

Yay for Temporal, web standard date management that doesn't suck. Talk by @ptomato.name. #JSNation

Yesterday I presented about #Temporal at #JSNation. In case you missed it, here are my slides! (with clickable links on the "learning more" page!) ptomato.name/talks/jsnati...

So grateful to see this work hit the world! Standards is an interesting process - I was the initial champion of this proposal, along with @b.trl.sn and @mattjohnsonpint.bsky.social. Since then @pipobscure.com , @jason-williams.co.uk, @ptomato.name and so many others have done more than we did.

Temporal is coming! ✨ @igalia.com and Bloomberg did a lot of work on this! So pleased to see it arriving! developer.mozilla.org/en-US/blog/j...

This weekend, several Igalians will be in Brussels for #FOSDEM 2025, which will take place on Feb 1st and 2nd. We will be giving talks covering different #OpenSource tech and topics and, as always, we are super excited to have hallway chats with everyone. 📜👇

Hey, there is a new blog post for people who are interested in pointer compression, isolate groups, and sandbox in V8. dbezhetskov.dev/multi-sandbo...

Check out all of the amazing work done by our compilers team in 2024! 👀 blogs.igalia.com/compilers/20...

I gave a remote talk at JSNation US in November, on Temporal, the modern way to handle dates and times in JS, coming soon to a JavaScript engine near you. Now the recording and transcript of that talk is published! gitnation.com/contents/tem...

Are you a developer who has a browser use-case for ShadowRealms? Does it solve a specific need for you that current technology (iframes) can't? If you answered yes and can share these with me, let's chat. (DMs are open). Please repost for visibility/reach. #WebDev

ECMAScript excitement 😉 Congrats to Ujjwal Sharma on advancing Intl.DurationFormat to Stage 4 at TC39 today 🎉 Intl.DurationFormat enables language-sensitive duration formatting. Example: 10000 seconds ➡️ 2 hours 46 minutes 40 seconds github.com/tc39/proposa...
