The Khronos Group announced today they have begun working on SYCL SC as a safety-critical variant of this heterogeneous compute programming model...

I've been playing around with the current development state of Fedora 38 the past few days on several test boxes. While only reaching Fedora 38 Beta this week, it already feels quite polished and stable.

KDE developer Xaver Hugl has written a blog post how the KWin compositor's DRM back-end has been working to move itself off GBM surfaces (gbm_surfaces) to instead allocate buffers directly and import them into EGL. This ultimately should be a win for the KWin compositor once everything is complete...

The Ubuntu 23.04 "Lunar Lobster" development builds recently transitioned from Linux 5.19 as in use by Ubuntu 22.10/22.04.2 to a Linux 6.1 based kernel. This led some -- including myself -- to wonder if Canonical changed course and shifted to Linux 6.1 LTS instead of the Linux 6.2 kernel that has been out as stable since last month. Fortunately, that's not the case and Ubuntu 23.04 is preparing to soon land Linux 6.2 across all kernel flavors...

From early December to late February there was an absence of new Compute-Runtime updates for that open-source stack for providing OpenCL and oneAPI Level Zero support for Intel graphics hardware on Linux. It was out of trend as they worked to move from a weekly~biweekly release rhythm to a monthly release cadence while taking extra time for making various other changes too. After that three month lull, they are back to pushing out new compute updates and damn it's looking nice. At least in my testing, the progress they've quietly made over the past few months has been very nice for the compute stack compatibility/support and performance.

The ipmitool utility on Linux systems is widely-used for controlling IPMI-enabled servers and other systems.
