There's been work to get the Nix functional package manager available on Fedora Linux for those wanting to leverage its available packages or features like supporting side-by-side packages of different versions, atomic upgrades/rollbacks, non-root user for installing software, and other features. One of the hurdles though is that the Nix package manager relies by default on the /nix directory, which goes against Fedora's default directory requirements. Now though the Fedora Engineering and Steering Committee (FESCo) has granted permission for using the /nix directory hierarchy...

This affected a variety of Intel graphics hardware and software while now has finally been tracked down with the problematic code removed. This is a big improvement for Linux gamers on Intel graphics...

A big patch series was posted today for the Linux kernel that would allow enabling/disabling CPU security mitigations at run-time rather than the current handling that can only be managed at boot-time via various Linux kernel command-line arguments. Thus due to changing security needs, differing workloads mandating different CPU security concerns and the like, this proposed feature would allow Spectre, Meltdown, and other CPU security mitigations to all be toggled at run-time...

While more code enabling Apple Silicon is reaching the mainline Linux kernel, a lot of important functionality so far remains under development or out-of-tree in the downstream Asahi Linux repository. One piece that's quite important for modern computing and still working its way to the mainline kernel is enabling USB3 functionality with Apple Silicon devices on Linux...

Now that the Linux 6.18 merge window is over with Linux 6.18-rc1 having released yesterday, here is a look at all the interesting new features and changes to find with this kernel.
