Back in April I wrote about Coreboot seeing AMD Picasso APU enablement work as the first Zen/Ryzen processor target being handled by this open-source BIOS alternative. It now looks like that Picasso support is all squared away and ready for use by future AMD-powered Google Chromebooks...

While there is another nineteen years to go until the Year 2038 problem manifests, the GNU C Library "glibc" is one of the key software components still needing some fixes for this issue where this problem where storing the Unix time as a 32-bit signed integer will wrap around and become a negative number...

While just being a few days into the two-week long merge window for Linux 5.3, it's certainly another busy cycle even when considering the summer months tend to be a bit slower for developers...

One of the areas that I always have "fun" benchmarking for new CPU launches is looking at the compiler performance. Following the recent Ryzen 3000 series launch I carried out some initial benchmarks looking at the current Zen 2 performance using the newest GCC 9 stable series with its "znver2" optimizations. Here is a look at how the Znver2 optimizations work out when running some benchmarks on the optimized binaries with a Ryzen 9 3900X running Ubuntu 18.04 LTS.

AMD's GPUOpen group has released a new version of their GPU Performance API (GPA) with Navi support...

While currently Ubuntu makes use of GNOME Software as their "software center" (or "app store") with Snap integration, as we wrote about recently Canonical has begun writing their own Snap Store. Given this and that they don't plan to use GNOME Software in Ubuntu 20.04 LTS and thus have taken their developers away from working on the upstream support, GNOME developers are planning to disable the Snap plug-in for GNOME Software...

The recent work on enabling "-Wimplicit-fallthrough" behavior for the Linux kernel has culminated in Linux 5.3 with actually being able to universally enable this compiler feature...

The scheduler changes for the Linux 5.3 kernel are as busy as ever...

Microsoft's exFAT file-system is more than one decade old and while there has been out-of-tree efforts, the mainline Linux kernel as of yet does not support the file-system even with it appearing on more SD cards and other devices. But there is now a renewed effort to get an exFAT driver into the Linux kernel...
