Ladybird’s lead developer ported LibJS, the browser’s JavaScript engine, from C++ to Rust in about two weeks using human-directed prompts and multiple AI reviews, achieving byte-for-byte identical output between the Rust port and the original C++ baseline; the thread also explores Rust’s role in browser development, interop with C++, and the broader implications of AI-assisted coding in large projects.
Rust Coreutils is advancing toward full GNU Coreutils compatibility, with FOSDEM 2026 highlighting Ubuntu 25.10’s adoption, rapid bug fixes, and ongoing cross‑platform improvements; the project aims to mirror Rust‑based success for other Linux tools, supported by growing contributions and a slide deck/video from the talk available at fosdem.org.
WhatsApp deployed a Rust-based media library across billions of devices, replacing 160k lines of C++ with 90k lines of Rust to boost memory-safety and performance. Sparked by the Stagefright vulnerability, the rollout used fuzzing and tests to ensure compatibility, and introduced Kaleidoscope checks to flag dangerous, non-conformant, or spoofed files. The effort spans Android, iOS, Mac, Web, wearables, and more—the largest Rust deployment on client-side platforms—and signals broader Rust adoption for defense-in-depth security.
Skeptics scrutinize Cursor’s claim of an autonomous, from-scratch browser built by hundreds of AI agents. Discussion shows the project uses open-source components (notably Servo) and only reached a compiling state after human intervention, with doubts about actual JS execution and browser functionality. Critics say the hype outpaced verifiable evidence of a working browser built entirely by autonomous agents.
Rust director Alistair McFarlane offered $25 million to buy Amazon's struggling MMO New World as it heads toward shutdown, urging a community-led approach with publicly hostable servers; whether the bid is serious is unclear and Amazon has not commented, but the move underscores New World's troubles and has drawn attention from other developers, including Hytale's creator.
Linux 7.0 is preparing improvements to inline C helpers into Rust during LTO kernel builds, involving new annotations and patches to enhance support for Rust and LLVM/Clang's LTO capabilities, with potential performance benefits.
Fjall 3.0, a Rust-based log-structured key-value storage engine similar to RocksDB, has been released with significant performance improvements, new APIs, enhanced data checksumming, and default compression for large values, making it a competitive option for embedded database solutions.
The article predicts 2026 will be a pivotal year for Linux and open-source, with continued growth in desktop adoption, the formalization of Rust as a core language for Linux, the rise of immutable Linux distributions, enhanced security measures, and open-source playing a crucial role in AI development, despite challenges faced by Firefox.
GNOME's end-of-year code stats reveal that 44.8% of core apps are written in C, with significant portions in Vala, JavaScript, and Rust, especially in community apps where Rust is more prominent. C dominates the core components, but Rust is gaining popularity in community projects.
The article reviews the most significant Linux kernel developments in 2025, including increased Rust integration, community decisions on file systems like Bcachefs and Btrfs, hardware support updates, and Linus Torvalds' commentary on kernel policies and architecture proposals, highlighting ongoing innovation and challenges in kernel development.
The article discusses how uv's impressive speed improvements stem from treating Python packaging as a well-defined systems problem, rather than solely relying on a Rust rewrite. It highlights the importance of standardization, good tooling, and the influence of commercial projects in overcoming longstanding issues in Python's ecosystem, emphasizing that language choice is less critical than thoughtful design and implementation.
Ubuntu Linux in 2025 has focused on migrating to Rust-based system tools like sudo-rs and Rust Coreutils, exploring performance optimizations, enhancing ARM64 support, and planning for the upcoming Ubuntu 26.04 LTS release, despite some challenges with Rust transitions and security vulnerabilities.
Microsoft aims to replace its entire C and C++ codebase with Rust by 2030, leveraging AI and automation tools to facilitate the transition, driven by a goal to improve security and reduce technical debt, with significant investment in new tools and talent.
Microsoft plans to replace its legacy C and C++ code with Rust, leveraging AI and human expertise to modernize its software infrastructure, including the Windows kernel, aiming for a significant shift by 2030 to improve security and performance.
Microsoft plans to replace all C/C++ code with Rust by 2030 using AI-driven refactoring tools, aiming to modernize its codebases and eliminate technical debt, with a focus on automating large-scale code translation and development.
