• Qt ☛ Qt for Android Automotive 6.9.2 is released

  The latest patch release of Qt for Android Automotive 6.9.2 was released. This release is based on Qt 6.9.2 with over 550 bug fixes, security updates, and other improvements done to Qt base. There are no additional Qt for Android Automotive features delivered with version 6.9.2.

• The GitOps Plateau – Have We Stopped Innovating? [Ed: Cargo cult and hype]

  GitOps adoption is steady but innovation has slowed.

• CNX Software ☛ LWMalloc is a lightweight dynamic memory allocator for embedded systems

  LWMalloc is an ultra-lightweight dynamic memory allocator designed for embedded systems that is said to outperform ptmalloc used in Glibc, achieving up to 53% faster execution time and 23% lower memory usage.

• Kernel Space

  • Marcin Juszkiewicz ☛ Git worktrees and kernel development

    I have a feeling that each SBC which has landed on my desk has required some kernel work. This involved fetching things from the mainline, the distro kernel, other distro kernels, SoC-specific trees, etc.

    In the end, I ended up with several git trees copied into the “~/devel/sources/linux/” directory, and used this setup for most of my kernel-related activities.

• Rust

  • Rust Blog ☛ The Rust Programming Language Blog: Welcoming the Rust Innovation Lab

    TL;DR: Rustls is the inaugural project of the Rust Innovation Lab, which is a new home for Rust projects under the Rust Foundation.

    At the Rust Foundation's August meeting, the Project Directors and the rest of the Rust Foundation board voted to approve Rustls as the first project housed under the newly formed Rust Innovation Lab. Prior to the vote, the Project Directors consulted with the Leadership Council who confirmed the Project's support for this initiative.

    The Rust Innovation Lab (RIL) is designed to provide support for funded Rust-based open source projects from the Rust Foundation in the form of governance, legal, networking, marketing, and administration, while keeping the technical direction solely in the hands of the current maintainers. As with the other work of the Rust Foundation (e.g. its many existing initiatives), the purpose of the RIL is to strengthen the Rust ecosystem generally.

  • LWN ☛ Announcing the Rust Innovation Lab [Ed: They choose Seattle, Washington (Microsoft) and Microsoft GitHub (proprietary), which looks bad for Rust.]

    During the opening of RustConf 2025 in Seattle, Washington, the Rust Foundation announced a new initiative to provide financial and administrative support to open-source Rust projects. The first project to benefit from the new Rust Innovation Lab is Rustls, an implementation of TLS in Rust. The foundation welcomes inquiries from other projects. Dr. Rebecca Rumbul, Executive Director of the Rust Foundation said: Rustls is hopefully the first of many really good [...] projects that will find a home in the foundation.
