The article investigates improvements to Cargo's scheduler by analyzing its behavior through benchmarks of Rust build tasks and exploring alternative scheduling algorithms.

The Cargo Team is experimenting on the Rust nightly channel to reduce target directory size by defaulting to -Zembed-metadata=no, aiming to gather feedback on this potential improvement.

A blog post presenting a vision for improving Cargo, covering workflows like dependency management, build performance, adaptability, and maintenance, and inviting community input.

Explains the mutual exclusivity issue between sccache and incremental compilation: enabling both leads to 20GB incremental cache consumption and dependencies being recompiled each time. After disabling incremental, large third-party libraries compile once and are reused across projects, achieving a cache hit rate of 53–93% after the first compilation.

Charlie Marsh built a tool called 'hawk' using Codex to identify and remove dead code across Cargo workspaces, already used to delete thousands of lines from uv and Codex.

Rust 1.97.0 is released with symbol mangling v0 enabled by default, Cargo support for denying warnings, and linker output no longer hidden.

David Lattimore introduces Cackle, a tool that helps prevent supply chain attacks in Rust by using access control lists (ACLs) to restrict what dependencies can do, reducing the risk of malicious code being introduced via third-party crates.

The author details building a tool called bygge-zig that uses the Zig build system to compile Rust projects, replicating Cargo's functionality in far fewer lines of code, highlighting the differences and challenges.

A developer tool that converts OpenAPI V3 specifications (from URL or file) into AI agent skill markdown files, enabling efficient API interaction with reduced token usage.

NASA's 34th SpaceX commercial resupply mission launched to the International Space Station, carrying nearly 6,500 pounds of cargo and scientific experiments.
