Nginx TLS SNI routing, based on subdomain pattern

Nginx can be configured to route to a backend, based on the server's domain name, which is included in the SSL/TLS handshake (Server Name Indication, SNI).
This works for http upstream servers, but also for other protocols, that can be secured with TLS.

prerequisites

at least nginx 1.15.9 to use variables in ssl_certificate and ssl_certificate_key.
check nginx -V for the following:
```
...
TLS SNI support enabled
```

OS X Preferences

most of these require logout/restart to take effect

# Enable character repeat on keydown
defaults write -g ApplePressAndHoldEnabled -bool false

# Set a shorter Delay until key repeat

第二次

配置 shadowsocks

架设好 shadowsocks 服务端，在路由器上安装 shadowsocks 客户端，并配置 /etc/config/shadowsocks.json ，假设本地监听端口为 1080 。启动 shadowsocks

/etc/init.d/shadowsocks start

配置 privoxy

安装 privoxy openwrt 版。

Hot Swapping With Maven, Jetty and IntelliJ

Based on Configuring Jetty, Maven, and Eclipse together with Hot Swap

I've always been a bit jealous when it comes to the Play! framework and the great dev mode they have for hot swapping classes at runtime. Jetty has a configuration setting, scanIntervalSeconds, that mimics this when working with a more traditional WAR, but does so by looking for changes to a file and restarting the server.

Fortunately, Jetty also provides the ability to rapidly test code with hot swapping. No more server restarts. The trick to getting hot swapping to work is to attach a remote debugger to your Jetty process. The following instructions outline how to do this in IntelliJ (tested with IDEA 10.5 CE).

Modify your jetty-maven-plugin to ignore the scan interval

Open your pom and locate the plugins section

	import numpy as np


	def find_runs(x):
	"""Find runs of consecutive items in an array."""

	# ensure array
	x = np.asanyarray(x)
	if x.ndim != 1:
	raise ValueError('only 1D array supported')
