We're building the fast, deterministic and reproducible package manager Pixi for scientific and robotics workflows. Based on @condaforge & @robostack packages.

A new guest blog post: shipping "Common Lisp" with Pixi. If you want to support your own ecosystem or a new or old programming language without building the package manager for it, then this is for you!

Always great to see users that are having success with rattler / rattler-build, and cleaning up the misconceptions around Conda Community packaging:
> I found Rattler by chance, and replaced thousands of lines of bash nonsense with clean, declarative YAML. Then, embedded Rattler in my Rust code, and installed with a clean, declarative API (such fluent APIs).

It's been a crazy week for cyber security. I am proud that we are protecting @condaforge / Pixi users with Basilisk and pixi-audit, our new tools (links below). In the screenshot you can see the recent high-severity brotli vulnerability, and the backport that fixed it.
We helped to coordinate three security responses this week:
- Pixi 0.82.1 revokes the eMudhra certificate, please update
- PHP 8.5.12 was released by us on conda-forge
- litellm 1.107.0 quarantined and blocked on prefix

We are also working on CVE scanning for @condaforge (basilisk.prefix.dev/) which you can use through `pixi audit`: prefix.dev/blog/pixi-audit-b… - please try the beta and stay safe!

We’ll be at NVIDIA GTC Berlin next week!
We’ll be joining the Edge Round Table on Tuesday morning and the Startup Stack-a-thon on Wednesday.

We wrote a blog that's a little different from what we normally publish.
It's more focused towards starting out with ROS, and avoiding the complexity of installation. Is this interesting content for you? Should we make more of this?

Isaac ROS 5.0 is out and you can install it with Pixi!

Building bridges between open-source projects is a big part of why I joined @marimo_io.
I got to know the @prefix_dev folks through @SciPyConf, and worked together to make computational research easier to reproduce and share.
Special thanks to Julian and @rarts_ruby!
marimo now supports @prefix_dev Pixi sandboxes!
Share portable notebooks with dependencies beyond Python, including CUDA-enabled @PyTorch, ffmpeg and R.
Already using Conda or Pixi? Bring your ecosystem to marimo’s reactive notebooks, with Conda and PyPI requirements saved alongside your code.
The Pixi team is at ROSCON in Toronto - come find the yellow backpacks if you want to chat! We keep spotting Pixi in so many cool robotics projects and it's making us proud. To get a glimpse of what we're working on, join the talk about the EU CRA this afternoon!

NVIDIA Isaac ROS 5.0 brings AI agents to robotics development. 🤖
Announced at #ROSCon, the release adds agentic workflows, Isaac Skills, ROS 2 Lyrical support, GPU-accelerated libraries and NVIDIA Jetson support from Orin Nano to Thor.
Open source and available now 📖 nvda.ws/3VahoaA
If you see one of these people #ROSCON, they are likely from prefix.dev! Come say hi, we're friendly! 💛

We made it easy to install Isaac ROS! The new `isaac-forge` repository contains many upstream NVIDIA Isaac ROS packages to make them installable with Pixi. You can test it today on your #NIVIDA #Jetson!
No docker needed!

Congratulations to the Mojo 1.0 release @Modular! So glad to have you in our community, and seeing @clattner_llvm on stage with `pixi` in the background was definitely a highlight for us.
playground.rattler.build got a redesign and a recipe generator for PyPI, CRAN and CPAN.
Paste a package name, get a recipe.yaml back.
