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? prefix.dev/blog/getting-star… #ROS #ROS2 #robotics

Getting started with ROS 2 Communication

Get started with ROS 2 communication for anyone, anywhere, on any platform!

Isaac ROS 5.0 is out and you can install it with Pixi! prefix.dev/blog/isaac-ros-wi… #NVIDIA #IsaacROS #ROS #AI

Should we build Pixi for Nix packages and call it Nixi?

It was a play on letters with the word prefix, that was easy to pronounce and remember

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!

If you see one of these people #ROSCON, they are likely from prefix.dev! Come say hi, we're friendly! 💛 @OpenRoboticsOrg

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! github.com/wolfv/isaac-forge

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.

Use pixi global to install any project from source now. Pixi global supports the full package spec to configure the neccesary information to install it directly, without a pixi.toml.

Building a git repo that never heard of Pixi used to mean forking it. Now you declare the build backend inline and Pixi builds it from source.

uv has become ubiquitous enough that I haven't used default python toolchain, or others, in more than a year. Every project I've seen is uv now.

PEP 723 only covers Python and PyPI, so Pixi reads tool.pixi for the rest. Which means conda dependencies in a standalone script.

As our server grows (600+ channels!) we had to redesign our channel page. It offers you an easier way to find your own or other interesting channels to fetch packages from!

We've been driving one of the biggest changes to the conda ecosystem since its inception: repodata v3. Extras, conditional dependencies, and variant flags, expressed directly in the repodata. Now in beta 👇 prefix.dev/blog/repodata-v3-…
