• Red Hat ☛ Beyond a single cluster with OpenShift Service Mesh 3

  In my previous article, we explored the chaos of decentralized microservices and how a service mesh acts as a modern, unified platform to bring order to the network. We unraveled the core concepts, from the role of the sidecar proxy to the central authority of the control plane, and established why Red Hat OpenShift Service Mesh 3 is a powerful solution for today’s complex architectures. Beyond its single-cluster capabilities, the most significant advancement in OSSM 3 is its streamlined and robust support for a multi-cluster topology, which transforms a collection of independent clusters into a single, cohesive application network.

  • Hackaday ☛ Hackaday Podcast Episode 339: The Vape Episode, A Flying DeLorean, And DIY Science

    Hackaday Editors Elliot Williams and Tom Nardi start this week’s episode off with an update on the rapidly approaching 2025 Supercon in Pasadena, California. From there they’ll talk about the surprisingly high-tech world of vapes, a flying DeLorean several years in the making, non-contact pulse monitoring, and the potential of backyard radio telescopes to do real astronomy. You’ll hear about a dodecahedron speaker, a page turning peripheral, and 3D printed tools for unfolding boxes. They’ll wrap things up by taking a look at the latest generation of wearable smart glasses, and wonder if putting a bank of batteries in your home is really with the hassle.

  • The Register UK ☛ Bcachefs goes DKMS after Torvalds' kernel banishment

    The bcachefs file system, now "externally maintained" outside the Linux kernel codebase, offers packages of its first version to be loadable on the fly.

    The development of bcachefs has been officially jettisoned from that of the Linux kernel itself. At present, the work-in-progress kernel 6.17 still contains bcachefs code, but unmodified from the 6.16 release. In response, the project has published its first set of packages of a version that can be dynamically loaded as a DKMS module, as promised a couple of weeks ago in an email from project lead Kent Overstreet.

    It's available as an APT repository, which for the time being limits it to the Ubuntu and Debian family of distros.

    This is the code that would have been the newer revision inside kernel 6.17 – but Linus Torvalds banished it last month. This means that if you test on the current release candidate of kernel 6.17, there are two different versions of bcachefs available: the built-in one, which is the same code as in kernel 6.16, and alternatively the newer version available in the dynamically loaded DKMS code.

    Do you have the audacity to use Audacity? If so, our reviewer says he wouldn't consider you audacious for a second because this app is fantastic.

    • India Times ☛ Canonical says transforming telco infrastructure through secure open-source adoption

      Canonical, the distributor of the open-source operating system (OS) Ubuntu, said it is transforming the telecom industry’s infrastructure by driving the adoption of secure open-source solutions.

      “We have moved up the chain. Customers and partners are now using the Canonical stack for virtualisation and abstraction. There are now Kubernetes container and orchestration solutions,” Naeem Maver, Vice President (Asia Pacific), Canonical Ubuntu, said at the second-edition of the recently concluded ETTelecom 5G Innovation Summit 2025.

      • AMD Enables PyTorch on Radeon RX 7000/9000 GPUs with Windows and Linux Preview

        AMD has rolled out a public preview of ROCm 6.4.4 that finally lets PyTorch run natively on Windows and Linux for a broad swath of its consumer silicon. The update brings official framework support to Radeon RX 9000 (RDNA 4) and RX 7000 (RDNA 3) GPUs, as well as to select Ryzen AI 300 "Strix" and Ryzen AI MAX "Strix Halo" APUs, fulfilling a promise AMD made at Computex 2025 to make ROCm more cross-platform and developer-friendly. "At Computex this year, I shared our commitment to making ROCm a true cross-platform, developer-first stack. I said we'd bring ROCm to Radeon on Windows and Linux in the second half of 2025. I'm proud to say that today, we're delivering on that promise," says Andrej Zdravkovic, Senior Vice President and Chief Software Officer.
