One Year of Sponsored Servo Development
Last September, the Servo project announced that long-time maintainer Josh Bowman-Matthews (@jdm) would work part-time on improving the Servo contributor experience, entirely funded by the monthly donations on OpenCollective and GitHub. In his own words, here is a look back over the past year!

Principles for fast Tokio applications
A practical guide to building low-latency, high-throughput applications on the Tokio async runtime, written from experience debugging real production systems. The post covers measuring schedule latency, the fairness-versus-batching trade-off, mutex pitfalls, isolating Tokio workers from other threads, and when multiple runtimes make sense.

I made a build profiler to understand Bun's compile times
Lalit Maganti built buildprof, an open-source Linux tool that records every process spawned during a build and renders them on a shared timeline. He used it to investigate the 5x speed difference between Bun's Zig and Rust builds, tracing the bottleneck to Full LTO in the linker and a downloaded WebKit library that amplified it.

Guest Post: Rust Is Tier-1 Language at Microsoft
Victor Ciura from Microsoft DevDiv announces that Rust has achieved Tier-1 language status at Microsoft, meaning it now has a fully paved path from local development to production. The post introduces rustc_codegen_utc, a new Rust code-generation backend that connects the Rust compiler to Microsoft's native MSVC toolchain.

Introducing CUDA Rust: Two Tracks for Writing GPU Kernels
In September 2026, NVIDIA announced it is leaning into native GPU programming in Rust. CUDA C++ and CUDA Python are mature, enterprise-grade toolchains, and NVIDIA will be growing and maturing CUDA Rust into 2027 and beyond The systems layer of AI spans inference engines, serving infrastructure, drivers, and agent runtimes, and it churns constantly as models and techniques change. More and more of it is written in Rust, which catches whole classes of bugs at compile time…

React Now Rusted All The Way Out
Master.dev describes switching a 1,036-file React Router codebase from the Babel-based React Compiler to the new Rust-native version available via oxc, achieving a 17.6x speedup in the compiler phase and a 2.4x overall build improvement. The post also covers how to migrate using both the official Vite plugin and an alternative for React Router framework mode.

Dropping Swift entirely from our Bevy iOS crates
Rustunit explains dropping Swift from Bevy iOS crates in favor of objc2—why the Swift glue went away, what the new crates look like, and what it means for Bevy-on-iOS maintainers.

Visualizing Rust's Vtables: How dyn Trait Works In Memory
A Rust learner coming from C++ examines how dynamic dispatch works in memory, contrasting Rust's wide pointer approach, a data pointer paired with a vtable pointer, with C++'s in-object vtable pointer. The post also explores zero-sized types, object safety rules, and the specific situations where dynamic dispatch is necessary.

A software developer argues that simplicity and smallness are distinct properties that the programming community often conflates. Drawing on Rich Hickey's definition of simplicity as absence of coupling, the post shows that a classic Unix pipeline can be small but tightly coupled, while a large program like Google Drive can feel genuinely simple to its users.

Developing provably correct Rust code with Verus
Many open-source and industry software projects, including several here at Amazon, are embracing the Rust programming language, since it provides performance and flexibility similar to that of the C programming language, while its clever type system automatically prevents a variety of bugs and security vulnerabilities. The result is fast code that's more correct and secure than average.

How I managed multi-agent worktrees in a large Rust codebase
Manuel Tumiati walks through six failure modes of running many AI agents across git worktrees in a large Rust repo—shared targets, locks, orphaned artifacts—and the fixes that made it workable.

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.

What Zig felt like, coming from Rust
A Rust developer's first real Zig project: how the language feels for systems work—manual memory, comptime, error handling, and where it differs from Rust's ownership model and tooling.

The making of a very fast SPI flasher
localcc builds an Xbox 360 dual-NAND modchip and pushes an RP2040-based SPI flasher as fast as possible, replacing the SPI peripheral with PIO programs written in Rust, profiling with Tracy, and optimizing the USB path to approach the ~29 second theoretical read limit through the SMC.

by Rüdiger Klaehn It is done. After four years of work and various pivots we have released iroh 1.0. We have an expanding web site describing how iroh works under the hood, but we think it is important to also understand why we made the decisions that led to the current iroh. So here is a trip down memory lane / our commit history which highlights major turning points and design decisions.

Safe SIMD in Rust, even on the inside
Sergey Davidoff explains why raw SIMD intrinsics force unsafe code in Rust and how the fearless_simd crate removes unsafe even from its own internals, using CPU feature tokens, generics, and aggressive inlining while working around ABI pitfalls.

Compiling Rust to readable C with Eurydice
LWN's Daroc Alden looks at Eurydice, part of the Inria/Microsoft Aeneas verification project, which converts Rust into clean, readable C for high-assurance and C-only environments, covering its IR passes, how it handles generics, traits and monomorphization, and where it is and is not worth using.

Matt Keeter writes a hand-tuned AArch64 assembly interpreter for the Uxn virtual machine and finds it about 30 percent faster than his safe-Rust baseline, explaining why dispatch dominates interpreter time, how keeping VM state in registers and per-opcode dispatch help, and follow-up experiments from readers.
