Systemd Introduces A New & Practical Service For Dealing With PStore
Adding to the list of new features for systemd 243 is another last-minute addition to this growing init system... Systemd picked up a new service and while some may view it as bloat, should be quite practical at least for those encountering kernel crashes from time to time.
ZFS On Linux Has Figured Out A Way To Restore SIMD Support On Linux 5.0+
Those running ZFS On Linux (ZoL) on post-5.0 (and pre-5.0 supported LTS releases) have seen big performance hits to the ZFS encryption performance in particular. That came due to upstream breaking an interface used by ZFS On Linux and admittedly not caring about ZoL due to it being an out-of-tree user. But now several kernel releases later, a workaround has been devised.
Merging exFAT Support For Linux Is Being Talked About - Waiting On Microsoft's Blessing
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.
AMD Radeon Pro WX 3200 Announced As A Small Form Factor $199 USD Workstation Card
For those looking for a small form factor workstation-oriented graphics card or just a budget workstation GPU in general, AMD today announced the Radeon Pro WX 3200.

Not a particularly new feature itself, but recently Microsoft has begun promoting a workflow for developers of encouraging them to use Windows 10 to do Linux development by leveraging Windows Subsystem for Linux (WSL) and Visual Studio Code Remote.
Linux's 32-Bit Kernel Has Been Buggy Since Being Mitigated For Meltdown
Whether you like it or not, the Linux kernel's x86 32-bit support has already begun suffering some minor forms of bit rot. Most kernel developers are no longer actively testing x86-32 and distribution vendors are beginning to drop 32-bit support. The latest example of x86 32-bit's effectively demoted state is some buggy undefined behavior functionality living within the mainline kernel for the past year since the Meltdown mitigations landed.
With An Out-Of-Tree Kernel Patch You Can Finally Read/Write To The SSDs On Newer Macs
While Apple computers once ran well with Linux, that's not been the case in recent years particularly for MacBook Pros but now really all newer Apple computers have become a mess on Linux. There's been really messy issues in trying to run Macs on Linux. With MacBook Pros from recent revisions, it's now only finally possible for Linux to read/write to the solid-state drive if using an out-of-tree patch.

AMD Radeon RX 5700 / RX 5700XT Linux Gaming Benchmarks
While last month we could talk all about the specifications for the Radeon RX 5700 series, today the embargo has lifted concerning the Radeon RX 5700/5700XT graphics cards so we can finally talk about the actual (Linux) performance. The road is a bit rougher than we had hoped, but it's possible to drive these new Navi graphics cards today using their open-source graphics driver stack at least for OpenGL games/applications. Over the weeks ahead, the Linux driver support for Navi will continue to improve.
