Canonical Releases "WLCS" Wayland Conformance Suite 1.0

While Ubuntu is not currently using Wayland by default with its GNOME Shell desktop and it doesn't look like they will try again until Ubuntu 20.10, the option is still available and they continue working in the direction of a Wayland Linux desktop future. One of their interesting "upstream" contributions in this area is with the Wayland Conformance Suite.

MDS / Zombieload Mitigations Come At A Real Cost, Even If Keeping Hyper Threading On

The default Linux mitigations for the new Microarchitectural Data Sampling (MDS) vulnerabilities (also known as "Zombieload") do incur measurable performance cost out-of-the-box in various workloads. That's even with the default behavior where SMT / Hyper Threading remains on while it becomes increasingly apparent if wanting to fully protect your system HT must be off.

Facebook Is JIT'ing C++ Code To Treat It Like A Crazy Fast Scripting Language

Facebook has worked on various programming language innovations over the years from all their work on HHVM at a time when PHP was slow to working on a super fast C/C++ pre-processor to other open-source language work. Their latest work in this area is on supporting just-in-time compilation of C++ code to treat it like a scripting language.

Dropped Linux Kernel Drivers Occasionally See Revival - FDOMAIN Gets Second Chance

When drivers get dropped from the Linux kernel it's generally due to hardware being no one cares about anymore that hasn't been produced in many years and the code often falls into disrepair to the point that the only logical way forward is dropping the driver. That happened last year to the "FDOMAIN" driver but as does happen every so often (albeit rare) thanks to the code being still obtainable through Git and the nature of open-source, interested parties can step up and revive the code.

Developers Start Debating Whether To Block Password-Based Root SSH Logins For Fedora 31

While upstream SSH has disabled password logins for the root user as their default configuration the past number of years and that has carried over into being the out-of-the-box behavior for many operating systems, Fedora continues allowing password-based SSH root log-ins by default. But with the next Fedora release they are thinking about changing that default behavior.

NixOS Takes Action After 1.2GB/s ZFS Encryption Speed Drops To 200MB/s With Linux 5.0+

The change in Linux 5.0 that initially broke ZFS On Linux compatibility ends up being pretty nasty for the ZFS encryption performance... A NixOS developer reports that the functions no longer exported by Linux 5.0+ and previously used by ZoL for AVX/AES-NI support end up dropping the ZFS data-set encryption performance to 200MB/s where as pre-5.0 kernels ran around 1.2GB/s.

Fedora 30 Wayland vs. X.Org Graphics Benchmarks On GNOME Shell

In the run up to the Ubuntu 19.04 release I ran various gaming/graphics benchmarks looking at different desktops and X.Org vs. Wayland sessions. Check that article out if interested in the situation while this posting is just some complementary data I did from Fedora Workstation 30 when looking at the graphics performance under GNOME Shell's X.Org and Wayland sessions.
