The amazing @catppuccintheme has chosen the magic wand as the icon for a Pixi manifest. Should we make it the official Pixi logo?

Don't worry, Paxton (our mascot) will stay!

Ever wondered where all my GitHub contributions come from? I have document a week's worth of @conda-forge.org contributions: uwekorn.com/2025/09/18/w...

I plan to do this for 2-3 more weeks to get an overview where I spent my time. I hope there is also content in there that helps others.

2025-37: A week in conda-forge

While I spent the majority of my time on QuantCo-internal (often strategic, non-code) work, my GitHub profile still hovers around 8,000 yearly contributions. Part of this is through my internal work, ...

Our server has recently delivered more than 1.000.000 packages for the first time. We've hit that mark a few more times since. Seeing this constant growth is fascinating and we are confident that our infrastructure will scale well beyond this number!

It's always a pleasure to get invoices from Azure. Why? Because it means our @condaforge.org sponsorship is being used! We have been sponsoring a big Windows machine through CirunHQ for the past year to build PyTorch, libmagma, and other hard-to-build software for Windows.

We're continuing our little deep dive series into Conda packaging. Mutex packages are useful to guide the SAT solver into specific parts of the dependency tree, and globally select either a GPU or CPU variant or similar features for an environment. prefix.dev/blog/what-a...

Mutex packages in the Conda world

Mutex packages are a useful mechanism to guide the solver towards certain dependencies, mutually excluding other dependency trees.

🔒 We're dogfooding sigstore attestations for our nightly releases of build backends. Really nice to see it in action! We will blog more about pixi-build and pixi-build-cmake soon.

We are full of ideas on how to expand on this and already excited to continue this work with funding from an OpenSSF technical initiative. Also, thanks to Trail Of Bits who made the CEP-27 enhancement proposal extremely solid thanks to their depth of knowledge.

This example perfectly shows how easy it is to cryptographically attest who built a given package thanks to Sigstore and upload it using rattler-build to prefix:

We would love to chat more about this. We can fix this in two ways: adding the package to conda-forge or building from source with our new build backends. Let us know what packages are outdated or missing!

Another deep dive in the technology behind Conda package managers: file linking! Did you know that there are symlinks, hardlinks and reflinks? Reflinks are the best – copy on write is space efficient and isolates the cache.

What linking means when installing a Conda package

Package managers face a fundamental challenge: how to efficiently place files from a package cache into multiple environments without excessive disk usage or compromising isolation.
