🛠️ Talk Spotlight: Why does scipy use pixi.toml? @rarts_ruby explains how Pixi solves scientific Python's toughest dependency challenges; C++, Rust, CUDA, Fortran, all in one tool 🚀 #SciPy2026 🔗 scipy2026.scipy.org

📣 Thank you to our Gold Sponsor @prefix_dev for supporting #SciPy2026! Your work on Python packaging makes the entire open-source ecosystem faster and more reliable. 🐍 🔗 scipy2026.scipy.org

⚡ Tutorial Spotlight: Reproducible CUDA doesn't have to be complicated! Matthew Feickert, Ruben Arts & Katrina Riehl will show you how to easily create reproducible scientific and AI/ML environments that leverage GPU acceleration across multiple machines and platforms with Pixi.

@iuliaferoli Aka the best toys!

@rarts_ruby Highly complicated, souldering-required electronics toys 😅

Biggest build I’ve taken on in a while just landed on the desk 🤖🦆 Open Duck Mini V2, an open source mini animatron inspired by the Disney Imagineers’ BDX droid. 14 Feetech servos, a Pi Zero 2W brain, and a sim2real RL policy doing the walking. Pretty much the full Physical AI stack in one tiny waddling package. Full build coming on YouTube soon! Huge thanks to @tnkrdotai for sending the kit. Project repo and docs: tnkr.ai/open-duck-mini… Let’s get Back To Engineering! #robotics #physicalAI #openduck

Damn I should have used a picture with our new logo! Excited to give this talk though!

@alexchenfeng I was just searching for these! Nice work

prefix.dev/channels/cinen… Built my reachy mini conda package on rattler-build. #Pixi #PrefixDev #RattlerBuild

@DavesRoboShack Great! Do they have a stand, presentation or logo that I should be able to notice?

@rarts_ruby At ICRA, you can look out for my research group, SpaceR. Maybe you can showcase them pixi 😉

Going to #ICRA! What should I try to run on an airport MacBook this time? Last time we ran #ROS RViz on an airport MacBook with #pixi

@iuliaferoli This exact experience is what gets me out of bed in the morning! We, @prefix_dev, are working everyday to make this problem less of an issue! Please give Pixi another try and hit me up where you're blocked, we need to show the world what the experience could be!

expectations vs reality of getting into robotics: everyone posts dancing humanoids and simulations you: version hell, hardware incompatibilities, computer catching fire the moment something works real boots on the ground physical AI reporting.

@Fmrico I'm so sorry for missing the context, my condolences!

@rarts_ruby I had terrible personal news on Saturday. See my other last post

One of the hardest talks of my career 😢, but it is done. Invited keynote titled "Designing Navigation Frameworks in ROS 2" at the 8th International Workshop on Robotics Software Engineering (RoSE’26) within #ICRA2026, the most important Robotics conference in the world.

If you want to come talk about robots (or turtles) we're holding a meetup on Tuesday night. luma.com/xayz5tru

Increasing the security of our users and the ecosystem is a top priority for us. That's why we've added OAuth2 login flow with scoped tokens for a better `pixi auth login` experience, and scoped "Trusted Publishers" & API Keys Read more: prefix.dev/blog/pixi-auth…

@AlexisPaques 100%

Who else has a problem with the growing amount of "special config files" on the top level of repos?

Thanks, Rubén Arts, for the opportunity of participate in the Pixi blog 🤓 prefix.dev/blog/pixi-at-i…

Guest blog post by @fmrico! See how Pixi and RoboStack improve his workflow at Universidad Rey Juan Carlos, improving teaching and robotics projects. prefix.dev/blog/pixi-at-i… #ROS #robotics #opensource

Want to understand why more and more Scientific Python projects are addopting Pixi? We'll give an overview during our talk at #SciPy2026 !

The latest version of Pixi comes with a new lockfile "v7"! It locks down build dependencies for the first time, making your builds even more reproducible. And of course fixes a number of issues. Read more in our blog post: prefix.dev/blog/lock-file…
