Tmux 快捷键 & 速查表 & 简明教程

启动新会话：

tmux [new -s 会话名 -n 窗口名]

恢复会话：

国内从 Docker Hub 拉取镜像有时会遇到困难，此时可以配置镜像加速器。

Dockerized 实践 https://github.com/y0ngb1n/dockerized

sudo apt install openjdk-8-jdk-headless

	import sys
	import numpy

	import cv2


	def comic(img):
	# do edge detection on a grayscale image
	gray = cv2.cvtColor(img, cv2.COLOR_BGRA2GRAY)
	edges = cv2.blur(gray, (3, 3)) # this blur gets rid of some noise

	#如果没有root的话(gateway没法设, dns也没法设), 则不使用系统的usb tethering而是使用gnirehtet而更简单些:
	https://github.com/Genymobile/gnirehtet
	sudo iptables -t nat -A OUTPUT -p udp ! -d 127.0.0.1 --dport=53 -j DNAT --to 192.168.0.25:53
	./gnirehtet run
	(可以设置unbound.conf的verbosity: 3<\n> logfile: unbound.log<\n> log-queries: yes 来观察是否生效, log文件位置可以用lsof -c unbound看到)
	用来收android的更新包非常快, 打google voice也是这个gnirehtet+iptables可以用, 用手机上的lantern或wireguard应用都不行

	#手机usb线连pc并启用tether
	(manual switch on: settings/network & internet/hotspot & tethering/usb tethering
	default on: settings/system/developer/networking/select usb configuration/rndis(usb ethernet)
