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

You can now publish "Channel Notices" on prefix - tell your users what's new in your channel! These will be shown in the channel overview, and in Conda, Pixi and other tools.

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

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.

playground.rattler.build got a redesign and a recipe generator for PyPI, CRAN and CPAN. Paste a package name, get a recipe.yaml back.

pixi update --offline now resolves against only what you already have: the package cache and local file:// channels. Air-gapped machines, planes, CI without egress.

Pixi now fully supports archspec, so you can create CPU-optimized environments and let Pixi handle the installation logic. Read more about it in the blogpost we updated: prefix.dev/blog/building_cpu…

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.

Conda packages can have extras now. Optional dependency groups you declare and then consume, via v3 repodata. Plus when conditions and variant flags. This should also be available on conda-forge in the near future! 📖 : pixi.prefix.dev/latest/conce…
