Voxlocal: a minimal voice agent written in Rust

Sam Khawase walks through building Voxlocal, a minimal local voice agent in Rust, explaining each stage of the pipeline from audio capture and Whisper speech recognition through text normalization, embeddings and retrieval, LLM tool routing and Piper speech synthesis, and measuring where the time goes.

C for Rust Programmers

A guide to the C programming language written from the perspective of someone who learned Rust first. BD103 walks through the surprising and unexpected parts of C for Rust programmers, including booleans and headers, strings and pointer lengths, integer types like size_t, the arrow operator, and the memory safety pitfalls Rust usually prevents.

Property Testing with Agent Swarms

Inanna Malick shows how to have coding agents build property-testing machinery (reference models, generators and assertions) for a repo, then turn the failures into small, reviewable fixes. Pointed at OpenAI's Codex, the public playbook found thirteen distinct correctness bugs, and runs on jj, uv, Prometheus and Babel produced merged upstream fixes.

Generic Const Args and You

Back in June of 2024 at RustFest Zürich, the Const Generics project group first discussed a new design for supporting more complex uses of generic parameters in Const Generics. Since then, we've continued to refine the initial design and have implemented the new design as a family of features dubbed "Generic Const Arguments" (GCA for short).

Writing Rust code that's faster than state-of-the-art libraries by asking agents to make the code faster

Max Woolf shows how iterative agentic coding—prompting agents to repeatedly speed up Rust code—produced solutions faster than established libraries, with concrete methodology and caveats.

Testing WebGPU data layouts with Facet

Matt Keeter shows how Facet reflection plus naga lets Rust unit tests catch WGSL/Rust struct layout mismatches—padding on mat3x3, dynamic arrays, and field offsets—before GPU hangs force a reboot.
