CaddyStaticServer

Install canddy on rpi via:

# sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https -y
# apt-cache search caddy
# curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
# sudo apt update
# sudo apt-get install caddy -y

Configuration files:

$ cat /etc/caddy/Caddyfile 
# The Caddyfile is an easy way to configure your Caddy web server.
#
# Unless the file starts with a global options block, the first
# uncommented line is always the address of your site.
#
# To use your own domain name (with automatic HTTPS), first make
# sure your domain's A/AAAA DNS records are properly pointed to
# this machine's public IP, then replace ":80" below with your
# domain name.

:80 {
	# Set this path to your site's directory.
	root * /media/sda/ucc
	# Enable the static file server.
	file_server browse {
	hide .git
}

basicauth * {
cwgo gowugowuoguwougowugouwogue
}
	# Another common task is to set up a reverse proxy:
	# reverse_proxy localhost:8080

	# Or serve a PHP site through php-fpm:
	# php_fastcgi localhost:9000
}

# Refer to the Caddy docs for more information:
# https://caddyserver.com/docs/caddyfile

The password could be generated via caddy hash-password.

Reload the server:

$  sudo systemctl reload caddy

Steps

Install kde desktop environment:

$ sudo apt install -y kubuntu-desktop

Install libvirtd and remove default qemu, then install compiled qemu:

$  sudo apt install -y libvirt-bin
$  sudo apt remove qemu-system-x86
// Go to   qemu source code: 
#  make install 
# qemu-system-x86_64 --version
QEMU emulator version 4.2.0 (v4.2.0-dirty)
Copyright (c) 2003-2019 Fabrice Bellard and the QEMU Project developers

Install virt-manager for managing the vms:

$ sudo apt install -y virt-manager
$ sudo systemctl enable libvirtd
$ sudo systemctl start libvirtd

Install win10 using following configurations:

vm configuration:

Added the qemuargs:

virt-xml win10 --edit --confirm --qemu-commandline '-set device.hostpci0.x-igd-gms=1'

libvirt configuration

libvirt hooks for pre-set vfio and post release vfio equipments:

记录步骤

我看还是用私有的笔记来记录吧

WorkingTipsOnRPIvpnServer

变更(piap->pivpn)

主要修改如下:
本来用来做公司的AP,但是因为需要，弄成了家里的pivpn,

1. 关闭了hostapd: sudo systemctl disable hostapd
2. 关闭了xray sudo systemctl disable xray
3. 关闭了shadowsocks sudo systemctl disable shadowsocks
4. 关闭了pdnsd sudo systemctl disable pdnsd
5. 关闭了dhcpd sudo systemctl disable isc-dhcp-server
6. 关闭了motion(摄像头) sudo systemctl disable motion
7. 关闭了shadowsocks-libev sudo systemctl disable shadowsocks-libev

更改了网络配置:

$ cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
#source-directory /etc/network/interfaces.d
#auto wlan0
#iface wlan0 inet static
#  address 10.16.42.1
#  netmask 255.255.255.0
auto eth0
iface eth0 inet static
  address 192.168.1.117
  netmask 255.255.255.0
  gateway 192.168.1.1

WorkingTipsOnKylinOptimized

目的

关闭kylinv10桌面特效

方法

安装qdbus：

$ sudo apt install -y qdbus-qt5

/usr/bin下新建脚本文件switchoffeffect.sh:

#!/bin/bash
qdbus org.ukui.KWin /Compositor suspend

/usr/share/applications下复制一个desktop模板用于撰写自定义启动文件:

$ sudo cp /usr/share/applications/kylin-weather.desktop /usr/share/applications/xxxxx-optimized.desktop

更改关键字段，最终效果如下:

[Desktop Entry]
Name=SwichOff
Name[zh_CN]=XX优化
Name[bo_CN]=གནམ་གཤིས།
Comment[bo_CN]=ཀྲུང་གོའི་དུས་ལྟར་གནམ་གཤིས།
Comment=Indicator applet for current weather conditions in China
Comment[zh_CN]=关闭特效
GenericName[bo_CN]=གནམ་གཤིས།
GenericName=China Weather Applet
Keywords=weather,china
Exec=sh /usr/bin/switchoffeffect.sh
Icon=kylin-weather
Terminal=false
Type=Application
X-GNOME-Autostart-Delay=10
Categories=System;Utility;
X-UKUI-AutoRestart=true;

开始菜单中点击: 设置->应用->开机启动, 点击添加，在弹出的添加自定义程序对话框中选择刚才创建的启动文件:

点击确定后，开机启动项如下:

重启后，桌面因为特效关闭的缘故，流畅度大有提升。
