I've suggested adding a command to docker to make listing at least the top-level PIDs in containers easier. ## Virtual Machines The two main technologies on Linux are Xen and KVM (and there's Bhyve for BSD). At my employer we sometimes use SR-IOV for direct network interface access, and NVMe for direct disk access. x series.

React got popular due to the virtual document object model (DOM) which enables it to enhance performance of web apps and PWA significantly. Usage of Virtual DOM allows efficient rendering where only certain part of webpage is rerendered speeding up performance. Absence of Virtual DOM results in less memory intensive applications.
