Cross instructions

These instructions cover:

building a cross toolchain
populating the new ROOT
making it chrootable using qemu-user to easily run "native" builds or tests (this is like a stage3 at the end)

You do not need to follow through to the end if you don't need a stage3-like root.

Run the command:
```
python pixiv_auth.py login
```
This will open the browser with Pixiv login page.

Docker使用久了，会残留很多中间生成的镜像，占用磁盘空间。

要清理Docker镜像，本来是挺简单的，一条命令就搞定了：

\usepackage{tkz-euclide} % checked for version 3.02c

Use the script below:

isInChina(function(inChina) {
  console.log('In china: ' + inChina);
})

	#!/bin/bash

	# Put under /etc/autoMemoryReclaim.sh

	# set variables at the top
	low_cpu_usage=50 # Note: We work with integer percentages (e.g., 50%)
	idle_time=2 # Minutes
	cached_memory_limit=1000 # MB
	percent_memory_to_reclaim=5 # Percentage as an integer
	wait_period=3

	#!/usr/bin/env bash

	command -v mediainfo >/dev/null 2>&1 \|\| { echo >&2 "mediainfo 命令不存在，请先安装 mediainfo。"; exit 1; }
	command -v ffmpeg >/dev/null 2>&1 \|\| { echo >&2 "ffmpeg 命令不存在，请先安装 ffmpeg。"; exit 1; }

	out_size=24
	length=$(mediainfo --Inform="Video;%Duration%" "$1")
	bitrate_all=$(echo "${out_size}*8192/(${length}/1000)" \| bc)

	bitrate_audio_orig=$(mediainfo --Inform="Audio;%BitRate%" "$1")

	#!/usr/bin/python3

	import asyncio
	import time
	import socket
	import argparse

	import aiohttp

	class MyConnector(aiohttp.TCPConnector):
