While Linus Torvalds didn't object to any of the features being worked on for this extensible scheduler framework that relies on user-space BPF programs, he was frustrated by the layout of the new C source files and remarked, "please don't do this disgusting thing...proper hierarchical filesystems have been available since 1965."

System76 today released COSMIC Epoch 1.1 as the newest feature release as well as being their first time bumping the minor version number since the December release of COSMIC 1.0.

The 46-year-old BASIC09 programming language has new compiler support with a front-end having been developed for the LLVM compiler stack. BASIC09 was developed in 1980 for the Motorola 6809 CPU running with the OS-9 operating system. With this LLVM compiler front-end, you can write BASIC09 code for modern software and hardware.

While the Linux 7.2 merge window doesn't wrap up until this weekend as the feature cut-off for new material, I have already begun some early benchmarks of the code currently staged for this next version of the Linux kernel. Linux 7.2 already was looking quite exciting with cache aware scheduling and other exciting new features while an unexpected surprise in my early testing this week was seeing some local network/socket performance improvements.

Over the years while working at Red Hat, Hans de Goede was known for driving many wonderful Linux laptop improvements benefiting AMD/Intel x86_64 hardware.

Interesting feature work for VMware virtualization on Linux now being pursued by Broadcom is to support zero-copy buffer sharing between the VM(s) and host hypervisor, which would equate to an efficiency and performance win.

Linux 7.2 has finally eliminated the strncpy API from the Linux kernel. The strncpy() function for copying up to a specified number of bytes has long been deprecated and after six years of work and hundreds of patches, no more users of the strncpy interface within the Linux kernel remained that it has now been eliminated.

20 June 07:19 AM EDT - Arm - More Performance

Merged for Linux 7.1 was ARMM64 NEON-accelerated CRC64-NVMe support for around 6x the performance out of that checksumming algorithm. The generic code had been a bottleneck in NVMe and other storage subsystem code of the Linux kernel with CRC64-NVMe being used to help verify against data corruption. Now for Linux 7.2, the NEON-accelerated code will also work for those still relying on 32-bit ARM.

The open-source world waited long enough for the GIMP 3.0 release that finally came last year with its GTK3 port and more, but for those with time on their hands this weekend and want to relive GIMP's past from long ago, GIMP 0.54 has been adapted for Flatpak to work on modern Linux desktops. What makes this version of GIMP from 1996 notable is that it was the last to use the Motif toolkit.
