How to identify the number of physical CPUs, a few cores, is hyper-threading or multi-core
Judge the basis:
1. CPUs with the same core ID are the same core hyper-threading.2. CPUs with the same physical ID are the same CPU-encapsulated threads or cores.
English version:
1.Physical ID and core ID are not necessarily consecutive but they unique. Any CPUs with the same core ID are hyperthreads in the same core.2.Any CPU with the same physical ID are threads or cores in the same socket.

KVM is short for Kernel Based Virtual Machine. It can use Virtual Hardware extension to provide virtualization software for multiple operating systems. KVM can be managed in two ways, one is command line, the other is a graphical interface.
Virt-Manager (Virtual Machine Manager) is the most frequently used management program based on KVM. It can create, edit, start, and pause Virtual machines.

KVM requires the CPU to support hardware virtualization. You can run
In Linux, many activities are related to time, such as process scheduling and network processing. Therefore, understanding the clock processing mechanism in the Linux operating system helps to better understand the operating methods of the Linux operating system. This article analyzes the clock Processing Mechanism of Linux 2.6.25 kernel, first introduces some hardware timers in computer systems, then, it focuses on the hardware clock and Software Clock processing processes in the Linux operatin

1. What is typescript.
Typescript is a superset of JS, it adds a static type of support to JS.
Read a paragraph of JS code:
var bill = {
name: "Bill",
Quack:function () {
document.write ("quack!");
}
function Sayquack (target) {
target.quake ();
}
Sayquack (Bill);This code will run wrong because, in Sayquack (target), Target.quake () should be written as Target.quack ().
Because JS is a dyn

Typescript typings
There are a lot of JavaScript libraries that inherit some of the JavaScript environment variables and syntax, and the typescript compiler does not support these in its native language. So we use the Typescript type definition file –d.ts file (that is, Typing
