Run a python script forever

In this section, we are going to show how to run a python script as a systemd service, allowing you to boot it at the start of a Linux machine and to maintain it alive.

Test method: Telegram Bot

We are going to use a very basic Telegram bot in order to test that our script will:

1. Automatically start when the machine boot
2. Automatically restart when it crashes/exits for whichever reason

If you are getting this in gdb on macOS while trying to run a program:

Unable to find Mach task port for process-id 57573: (os/kern) failure (0x5).
 (please check gdb is codesigned - see taskgated(8))

1. Open Keychain Access
2. In menu, open Keychain Access > Certificate Assistant > Create a certificate
3. Give it a name (e.g. gdbc)

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

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers
