  • Hackaday ☛ Hackaday Podcast Episode 341: Qualcomm Owns Arduino, Steppers Still Dominate 3D Printing, And Google Controls Your Apps

    The nights are drawing in for Europeans, and Elliot Williams is joined this week by Jenny List for an evening podcast looking at the past week in all things Hackaday. After reminding listeners of the upcoming Hackaday Supercon and Jawncon events, we take a moment to mark the sad passing of the prolific YouTuber, Robert Murray-Smith.

  • Bootlin ☛ Updated Buildroot support for STM32MPU platforms, ST BSP v6.1

    The buildroot-external-st project is an extension of the Buildroot build system with ready-to-use configurations for the STMicroelectronics STM32MP1 and STM32MP2 platforms. More specifically, this project is a BR2_EXTERNAL repository for Buildroot, with a number of defconfigs that allow to quickly build embedded GNU/Linux systems for the STM32MPU Discovery Kit platforms and Evaluation board.

  • Sebastian Wick: SO_PEERPIDFD Gets More Useful

    A while ago I wrote about the limited usefulness of SO_PEERPIDFD. for authenticating sandboxed applications. The core problem was simple: while pidfds gave us a race-free way to identify a process, we still had no standardized way to figure out what that process actually was - which sandbox it ran in, what application it represented, or what permissions it should have.

    • Request Workflow: Accept & Forward by Default and Clearer History

      Alright! Here we go again! This time with some small improvements to the request workflow: “Accept and Forward” is now the default action for requests that can be forwarded, and we have removed the confusing colors from the icons in the Comments & History timeline when adding a review. We started the redesign of the request workflow in August 2022. Then, in September 2022, we focused on the support of multi-action submit requests.

    • Dominique Leuenberger ☛ Tumbleweed – Review of the week 2025/41

      Dear Tumbleweed users and hackers,

      Week 41 started strong, with daily snapshots released, but unfortunately, we hit some roadblocks by the end of the week. A seemingly harmless rename of a snapper plugin caused quite some havoc in openQA, as SELinux was unaware of that change and consequently, a completely untrusted executable was blocked from messing around with the bootloader. Generally, exactly what we want – except in this case, it was an intentional rename of a file. The change has been retracted for now and will be given back to engineering.

      Our Debian User Group met on September 27^th for our first meeting since our summer hiatus. As always, it was fun and productive!

    • OMG Ubuntu ☛ This Extension Brings Live Calendar & Clock Icons to Ubuntu’s Dock

      You can bring the GNOME calendar, clock and weather app icons to life in Ubuntu with a GNOME Shell extension that makes them show real-time information, right on the dock. If you keep the clock, calendar or weather icons pinned in the Ubuntu Dock (or an equivalent, like Dash to Panel) and you find yourself wishing they were dynamic, like macOS’ native equivalents, this does it! If this sounds a bit familiar, you’ve got a good memory!

    • Hackaday ☛ A Function Generator From The Past

      It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina Neumryr]’s niche comes in building projects from old electronics magazines, and her latest, a function generator from the British Everyday Electronics magazine in April 1983, is a typical build.
