Octoconda - turning Github Releases into Conda Packages

Someone releases a great tool with perfectly working pre-built binaries on Github, but there's no Conda package. Octoconda helps out: It takes the release artifact and re-packages it for use in the Conda eco-system.

Flickzeug – or why patching source code is hard

TL;DR - we have extended the Rust crate diffy to be able to patch real-world source code with real-world patches, which is surprisingly hard! In the process we renamed it to flickzeug.

Publishing Conda Packages on Amazon S3

We worked together with AWS Deadline Cloud to improve S3 support in our tools! Pixi and rattler-build now seamlessly authenticate using default credentials on your system, making it simple to upload, download and index packages on S3 buckets.

S3 support in Pixi and rattler-build

We're excited to announce S3 support across our entire toolchain – rattler, pixi, and rattler-build now support the most common cloud storage standard, thanks to contributions from our friends at QuantCo. This vendor-agnostic approach to distributing Conda packages represents a major step forward for the ecosystem, offering teams the flexibility to host packages on any S3-compatible provider (AWS, Cloudflare R2, Backblaze B2, Hetzner, and more) with built-in authentication and minimal vendor lock-in.

Introducing Rattler: Conda from Rust

At prefix.dev we love Rust, but using conda/mamba from Rust is hard, so we started building Rattler, a set of crates that offer clean, compartmentalized building blocks for package management.
