Two things at completely opposite ends of the “Linux world”:
eBPF. It seems super promising for improving observability and security; especially performance of these concerns. It also strikes me as a risky architectural decision. Programmable privileged kernel code + JIT. What could go wrong… that validator sure is doing heavy lifting.
Valve flexing more muscle in developing Proton as it comes to terms with the fact Microsoft’s vertical integration (and monopolistic practices increasingly unfettered by government) will eventually be an existential risk to it. It is now ridiculously easy to install and run so many games on Linux, so long as you accept the devil you know and it’s DRMy platform. Definitely not perfect but it’s so vastly improved I’m comfortable calling it “night and day”
