QSOE: QNX-inspired OS with dual-kernel architecture (custom kernel & seL4)
by Yuri Zaporozhets 23 Jun '26

23 Jun '26

Hi! This is my project which I recently announced: https://qsoe.net Interestingly, when working in the shell (mksh-derived), the subjective "feeling" is that QSOE/N (with Skimmer) is ~10 times faster than /L :) . Launching e.g. "time ls" command confirms this: 0.1s for QSOE/L (with seL4) vs. 0.01s for QSOE/N. The work continues. Now I'm working on a video controller support for my SiFive Unmatched; then, when the _real_ text-mode console is there, I'll return to active QSOE developments. -- Regards, Yuri

RFC: Enabling uROS on seL4
by HHN 22 Jun '26

22 Jun '26

Hi Everyone, I have recently been experimenting with porting uROS to seL4. uROS (micro-ROS) is a very minimal version of ROS (Robot Operating System) - a well known robotics middleware suite. I have implemented the micro-ROS examples <https://github.com/micro-ROS/micro-ROS-demos/tree/kilted/rclc> and the necessary system to run them on seL4 over here <https://github.com/Johan511/sel4_uros>. A high level explanation of the work can be found here <https://johan511.github.io/posts/2025-01-19-uros-on-sel4/>. I do not have any prior experience with Operating system development or with ROS, so any critiques are much appreciated. Thank you -- Hari Hara Naveen
