One of the new Linux kernel features Google engineers have been working on is fs-verity for read-only file-based authenticity protection. Fs-verity is similar to dm-verity with a similar aim but is designed to work on a per-file basis for read-write file-systems rather than at the block level...

Solus, the promising Linux distribution started back in 2015 by Ikey Doherty that led to the creation of its own "Budgie" desktop, has been without its founder since this summer. While the circumstances under his decision to fade away from the project aren't clear, he is well and has shared this message to relay with the community...

With the Linux 4.20~5.0, the kernel is now VLA-free as a step towards being able to compile the mainline code with the LLVM Clang compiler or other non-GCC compilers. Another step in this direction has been merged this cycle and that is cleaning up the compiler attributes code...

With the increasingly popular RISC-V open-source processor instruction set architecture (ISA), there is the possibility for vendor-specific instruction set extensions. At this point the kernel has no infrastructure in place for its RISC-V port to allow for such bits, but that is being worked on as part of bringing up AndeStar RISC-V CPUs under the Linux kernel...

October was very interesting for Linux gaming with no AAA native game ports released but a heck of a lot more Windows games are now running nicely on Linux thanks to Steam Play / Proton / DXVK. So it's quite interesting to see Valve's just-published monthly Steam Survey results for the month prior...
