@socialent2026 For now yes.

Finally sharing what I’ve been building these past few months: Popkorner 🍿

I love movies. I wanted a simple, beautiful app for new trailers, watchlists and release alerts, for films and TV shows. So I built one.

You can also see what friends are watching and turn your reviews into shareable cards.

Try it on iPhone! I’d love to hear what you think:

@socialent2026 So cool ! I’d love to try your app but it’s not available in France 🥺

[Jean-Mathieu Saponaro @jmsaponaro]

@Joshua_WD Yes they do 😊

[Jean-Mathieu Saponaro @jmsaponaro]

And yes, there’s some AI in there but only to make it even more helpful ✨ Search in your own words, describe the mood you’re after, or ask questions about a movie or series.

No spoilers (unless you ask for them 🙈)

If they truly believe the risk is that high, and I think they do, then we need 100x more research and understanding of it. That requires them to openly share their models, datasets, training code, and agent traces.

@ChatGPT the markdown rendering on side panels is broken on the desktop app on Mac v26.721.81911.

[Jean-Mathieu Saponaro @jmsaponaro]

@claudeai can we also have a « Pet » hanging out on our screen like on the ChatGPT’s desktop app? 🦀 😄

[Jean-Mathieu Saponaro @jmsaponaro]

@OpenAI I find it crazy that Personal Skills defined on the ChatGPT Web App aren’t synced to the Mac OS desktop app. Is this being fixed soon ?

How does @datadoghq monitor the data and pipelines that power its own products?
I talked about this at DASH: Spark + Apache Iceberg Lakehouse behind products like Cloud Cost Management, tracking freshness, quality, and performance.

So many impressive product announcements at @dashdatadog today around « AI for Datadog » and « Datadog for AI ».
Exciting times at @datadoghq.
#DASH2026

[Jean-Mathieu Saponaro @jmsaponaro]

Excited to go to @dashdatadog conference for the first time! And as a speaker! I’ll talk about the data pipelines behind some of the @datadoghq products you use every day and how we unified and overhauled all the Data Observability tooling for our data teams. #DASH2026

Ever wondered what your AI agent was actually doing?
Lapdog by @datadoghq runs locally and traces reasoning and tool calls in Codex, Claude Code, and Pi. Free, no account required.

Toto 2.0, @datadoghq's TSFM, is out and state-of-the-art across time series forecasting benchmarks.
Trained on #observability data generalizing beyond it. Scaling works for time series just like it does for language.

@AmenaiSabuwala ✨ What’s the app on the first screenshot?

[Jean-Mathieu Saponaro @jmsaponaro]

Fascinating use of #AI in the real world...ahem...universe. ☄️

@Freyy_is This !

Has anyone tried the new #AppleStudioDisplay mic and camera for meetings? Can we ditch our separate studio mic and 4k webcams already for video calls? 🎥 🎙️ 🖥️

The Datadog plugin in Cursor is *unbelievably good*.

Has saved hours of my time in the past week.

[Datadog, Inc. @datadoghq]

See how Cursor uses Datadog MCP, now Generally Available, to bring observability-driven automation to life.
