Installing Arch Linux on VirtualBox in Windows 10

I recently upgraded to a new system, and instead of running Arch Linux natively I've decided to run it inside VirtualBox on Windows 10. Below I note down the steps I took, which closely follow the excellent wiki pages of archlinux. But along the way, I also noted a few other steps steps I took to make this system very comfortable, which you'll have to figure out for yourself if you like them or not!

Setting up Windows 10 to be ready

There isn't much of preparation required, given that I started from scratch, but I did have to setup my windows environment a little bit.

1. Install the windows package manager chocolatey
2. Install qBittorrent (which will be used to download an iso copy of arch) by running the following command from the command line choco install qbittorrent (recommended to run the command line as an adm

good, 你已经有了一个自己的shadowsocks代理了，现在想要把这个代理公布出去给所有人分享。
但是没有两个小时，代理就没法使用了，为什么？因为你需要额外注意以下事项（以下步骤需要比较高的linux技能）
本文只关注于确保shadowsocks服务还“活着”，如果你希望让其跑得更快，请参考 
https://github.com/clowwindy/shadowsocks/wiki/Optimizing-Shadowsocks

1、 shadowsocks的timeout设置
超时时间越长，连接被保持得也就越长，导致并发的tcp的连接数也就越多。对于公共代理，这个值应该调整得小一些。推荐60秒。

2、 检查操作系统的各种限制
对于openvz的vps，特别需要检查一下

一行 Python 实现树

使用 Python 内置的 defaultdict，我们可以很容易的定义一个树形数据结构：

def tree(): return defaultdict(tree)

就是这样！
