In a few years, the only proof something is real will be that it existed before AI did. julien.danjou.info/p/the-pre…

After a short stint in a startup that didn't go as expected, I'm back at @elastic, joining Elasticsearch's Analytical Engine team. There's tons of work, and I bring there — among others — my care for nice APIs and my knowledge of the Arrow ecosystem, lingua franca of analytics!

Allez, vu que c'est la tradition : « 🎼🎵🎶 c'est Noël c'est Noël cette m c'est Noël 🎵🎶 » (C'est la faute de @bluxte qui me l'a mise dans la tête 😂)
« C'est Noël, c'est Noël, c'est Noël » Comme chaque année, c'est le moment de ressortir Orinoco Flow ^^

My "following" feed is now just a few screens long here. Is it just me? Is it a new "feature" to drive people to the "for you" algorithmic mess or a paid account?

Sebi is an amazing devrel, a great engineer and an awesome human being. If you have the opportunity, you should definitely hire him!
🚨 So after 21 years of career, it finally happen, I have been let go from my company, in fact the complete marketing team has been let go ... It came really as a complete surprise, I was not expecting that at all since they were super happy with and the significant impact I had. Also the company is doing really well ... But it's life, it's not easy, I'm recovering slowly and I'm already looking for my next adventure. So if you are looking for a experienced IT professional with expertise going from advocacy (community, pre-sales & customers) to Java, with a lot of knowledge and opinions on Platform Engineering/k8s ecosystem and how all of this can be infused with AI, don't hesitate to ping me. Remote EMEA Also don't hesitate to RT this post. Love you all, my network of friends has already been beyond awesome helping when I told them in private last week.

Quand la domotique automatise l’inutile… et qu’on adore ça 😅 Merci à @bluxte @mathieupassenau @neonox31 et à toute l’équipe du @DevFestToulouse ! Trop cool d’avoir parlé des automatisations WTF et des données qu’on génère chez nous. À refaire !

Someone shared a fascinating visual of an AI agent moving through a real codebase - reviewing structures, making decisions, and committing changes. It’s a reminder that software development is quietly entering a new phase. xitter.cf/NostalgiaFolder/status…
Someone shared a fascinating visual of an AI agent moving through a real codebase - reviewing structures, making decisions, and committing changes. It’s a reminder that software development is quietly entering a new phase. Not automation in the traditional sense, but systems that can understand context, navigate complexity, and contribute meaningfully. We’re still early, but the trajectory is unmistakable: coding is becoming more collaborative between humans and intelligent agents than ever before.
Readers added context they thought people might want to know
This is a visualization of the history of a git repository not an AI agent exploring a codebase. gource.io

Let the gentle introduction begin! We've heard from you that we need to provide more getting started content. Last week we kicked off the series, and now we've got the first video! This tutorial walks you through Rerun's core concepts like entity paths, archetypes, and the blueprint system. With this knowledge, you can start visualizing robotics and computer vision data in minutes. By the end of this video, you'll understand how Rerun's logging architecture works, how to create synchronized 2D/3D visualizations, and how to navigate the viewer to debug multimodal data. youtu.be/eBmh5cuOZO8

Today was my first day at @rerundotio! I'm joining as a backend software engineer to build the "data platform for physical AI". The development of AI-powered robots (from vacuums to cars) requires new tools to build their model and analyze their behavior. 1/2

Rerun is building that platform, and I'm joining to work on Rerun Cloud, the data platform to store/query/analyze/enrich that data. It's all Rust with a good dose of Arrow, DataFusion, LanceDB and and cutting edge data tools and libraries. Pretty happy so far! 🤖🦀 2/2
