LXQT-QTermWidget的编译
LXQT的编译说明
https://github.com/lxqt/lxqt/wiki/Building-from-source
流程如下：
1.安装Qt5。
yum install qt5-qtbase-devel qt5-qtsvg-devel qt5-qttools-devel qt5-qtx11extras-devel
2.安装CMake，一定用要官方包安装，并编辑bashrc文件。
export PATH=$PATH:/cmake-3.15.3/bin
3.下载lxqt-build-tools编译工具并安装。
git clone https://github.com/lxqt/lxqt-build-tools.git
假如是解压在~/lxqt/lxqt-build-tools目录下。
则创建编译目录~/lxqt/build
构建指令如下：
cmake ../lxqt-build-tools
make && make install
它会安装至/usr/local的某个目录下。
4.下载
git clone git@github.com:kxtry/qtermwidget.git
使用CLion构建及编译即可。
此版本已经与原版不一样，有修改。
原版可能无法编译完成，原因是QString("sdfsdfds")会编译不通过，因为从Qt5.9版本开始，QString(char *p)设置成私有函数了。

GoLang的AST语法树
package main
import (
"fmt"
"go/ast"
"go/parser"
"go/token"
)
func main() {
// src is the input for which we want to print the AST.
src := `
// @router /login [post]
// @router2 /login2 [post]
package main
func main() {
println("Hello, World!")
}
`
// Create the AST by parsing src.
fset := token.NewFileSet() // positions are relative to fset
f, err := parser.ParseFile(fset, "", src, parser.ParseComments)
if err != nil {
panic(err)
}
for _, comment := range f.Comments {
fmt.Println(comment.Text())
}
// Print the AST.
ast.Print(fset, f)
}

nginx的惊群效应导至响应时间长变大，CPU消耗增加
在流控后台上，观测到单主机CPU消耗为27%左右，请求响应为3毫秒，甚至4毫秒。
经检查，发现nginx的配置为
worker_processes auto
主机为16核，因为auto的影响，会默认为16个进程。而在top指令中显示，nginx的消耗与flowservice持平，作为转发服务，nginx的消耗是不合理的。
考虑到nginx的惊群效应：每个请求，所有nginx子进程均会响应，导致过多无谓的CPU消耗,因为把work_processes改为4个。
果然，CPU消耗由27%降为20%,响应时间由原来4毫秒，降为1毫秒。
终端开发文档参考
终端如VT100,VT50，VT220等终端，其相关的文档都汇聚在这个网站上。

http://man.he.net/man4/console_codes【Linux Console Codes】【Linux下的console文档，是vt102的子集】
Vt102是vt100家族的第二代指令，在原有vt100基础上增加了行插入行滚动的几个指令。
