Project/Tooling Updates
Zed editor launches performant, aligned split diffs, detailing the engineering challenges of scaling this feature across its unique multi-file multibuffer architecture.
A status update on porting Rust to CHERIoT, detailing compiler adaptations for 64-bit capabilities on a 32-bit platform, core/alloc library support, and a notable tail call bug fix.
SeaORM 2.0 introduces native Apache Arrow and Parquet support, enabling direct schema derivation from entities for efficient columnar data export and import.
Benchmarking `bincode` `next`, `v1`, and `v2` reveals significant performance improvements across diverse encoding and decoding scenarios, with one minor regression in `v1`.
Introducing Almonds opeolluwa.github.io
Almonds is a new open-source, Rust/Tauri-powered local-first desktop workspace consolidating notes, tasks, and local AI with a strong emphasis on data ownership and self-hosting.
SafePilot v0.1 is the first public release of a self-hosted, open-source AI operations assistant featuring workspace isolation, policy controls, and integration routing.
Observations/Thoughts
Ubuntu's adoption of Rust for foundational Linux utilities is presented as a key example of the language "crossing the chasm" to the early majority, urging the Rust project to adapt its strategy for this new phase of growth.
Read Locks Are Not Your Friends eventual-consistency.vercel.app
`parking_lot::RwLock` can be significantly slower than `Mutex` in read-heavy Rust workloads with short critical sections due to cache line contention from internal atomic reader counts.
A Rust project built with detailed specs and Claude Code AI achieved near-zero functional bugs in its initial release, attributed largely to Rust's strict compiler.
A presentation on device-envoy, a Rust library using Embassy for simplifying embedded application development on microcontrollers.
Rust Walkthroughs
Optimizing a Rust Matrix SDK's room list sorting performance by tackling memory pressure, lock contention, and introducing data-oriented design, resulting in a 78x speedup.
Research
Explore Cargo Scan, a novel tool using Rust's type system and side-effect analysis to reduce third-party crate auditing to a median of 0.2% of lines of code.
Miscellaneous
