A Rust CLI helps LLM developers manage token counts, costs, and performance across multiple providers.
A Rust CLI tool for filtering semantic versions from input streams using a Lua-like query language, ideal for release management and CI automation.
SeaORM 2.0 introduces strongly-typed column access via `COLUMN.field_name` for improved ergonomics and compile-time type safety, alongside enhanced relations, pagination, and better Seaography integration.
Explains the token prediction process in a decoder-only transformer model using self-attention and feed-forward layers.
Achieve up to 200x faster N-dimensional interpolation than Scipy with InterpN, a `no-std` Rust library leveraging advanced optimizations like SIMD, const-unrolling, and PGO for embedded and scientific use.
Tako v0.5.0 introduces SIMD JSON for performance, a flexible plugin system for features like compression and rate limiting, GraphQL integration, enhanced routing, and developer experience improvements on its path to v1.0.
Observations/Thoughts
Just call clone (or alias) smallcultfollowing.com
Proposes a new Rust edition feature to automatically capture `clone`/`alias` in `move` closures and remove unnecessary `clone`/`alias` calls via a "last-use transformation" to simplify error fixing and enhance ergonomics.
A feature-by-feature comparison of Rust and Python highlighting their core differences in performance, safety, and development velocity.
An introductory video covering Rust setup, core concepts like ownership and error handling, data structures, and iterators (including Rayon for parallelism).
Explore bridging Rust and JavaScript using `wasm-bindgen` through Jakob Meier's Rust Zürisee talk, including live demos on bot detection and memory concepts.
A podcast exploring Rust in networking, featuring deep dives into projects like Fuchsia's Netstack3, Oxide's stack, Hyper, Tokio, Rustls, and interviews with their creators.
Rust Walkthroughs
A guide to building a hand-rolled, resilient recursive descent parser in Rust with full-fidelity CSTs using `logos` and `rowan`, focusing on robust error recovery and syntax design for language tooling.
