Nicholas Nethercote has published a new installment of his recurring guide to improving the performance of the Rust compiler, rustc. The post walks through practical contributions from September 2026, profiling work, and the techniques that have yielded speedups. It continues his long-running series, which developers and Rust project contributors follow for guidance on how to start optimizing the compiler themselves.
- 3PSSA: a non-transformer language model built from scratch in Rust●PSSA: A non-transformer language model written from scratch in Rust
A developer has released PSSA, a language model that does not use the transformer architecture, implemented entirely from scratch in Rust and published as an open-source project on GitHub. The project is drawing attention from programmers and machine-learning enthusiasts interested in alternatives to dominant transformer-based designs and in low-level implementations outside the usual Python ecosystem.

Matt Keeter has published a blog post describing how he tests WebGPU data layouts using Facet, a Rust library for reflection over data structures. The article walks through verifying that Rust struct layouts match what GPU code expects, a common source of subtle bugs in graphics programming. It is drawing attention from developers interested in WebGPU, Rust tooling, and safer GPU programming techniques.
- 5Rpi: Rust rewrite of the Pi agent claims 10× faster startup●Rpi – a Rust rewrite of the Pi agent, 10× faster startup
Developers are discussing Rpi, a new Rust rewrite of the Pi agent that reportedly starts about ten times faster than the original. The project is drawing attention in programming communities, where commenters are weighing Rust's performance benefits for command-line AI agent tools against the cost of rewriting working software.

Developer Armin Ronacher has published a lengthy write-up on Deser, an experimental project rethinking how serialization works in the Rust programming language. The piece examines the limitations of existing approaches like Serde and proposes an alternative design. The article is drawing attention from Rust developers debating whether the ecosystem's dominant serialization model needs rethinking.
- 11Developer builds pure-Zsh prompt engine rendering in 0.6ms●For years, developers optimizing their shell prompts have faced a binary dilemma: Starship:... # zsh # shell # opensourc
A developer has unveiled a shell prompt engine written entirely in Zsh, claiming render times of 0.6 milliseconds without relying on Rust, positioning it as an alternative to Starship, the popular cross-shell prompt tool. The project is drawing attention among developers interested in shell performance, open-source tooling and Zsh customization, with discussion framing it as a new option in a space long dominated by a two-way choice.
