微博工程师法则（Laws of Engineer in Weibo）：

1. 工程师必须牛逼
2. 除非抵触法则1，否则不能吹牛逼
3. 除非抵触法则1和2，否则开源才牛逼

QQ的XML消息格式整理

QQ可以使用xml的方式发送消息，以下为了方便描述统称为卡片。

发送方式

通过机器人的API进行发送xml即可，但是如果选择发送xml，那么其他如[image=xxx]、[@xxx]这些命令就不可使用了。整个消息只有XML。

基本结构

xml主要由msg,item,source这3部分组成

<?xml version='1.0' encoding='utf-8' standalone='yes'?>

# brew install nginx
sudo ln -s /usr/local/opt/nginx/homebrew.mxcl.nginx.plist /Library/LaunchDaemons/
sudo chown root:wheel /usr/local/opt/nginx/homebrew.mxcl.nginx.plist
sudo launchctl load /Library/LaunchDaemons/homebrew.mxcl.nginx.plist

# Why do you need sudo?
# If you want nginx to be able to bind to port 80, it will need superuser privileges

Recently, I use JMXterm to collect info about Java JVM via JMX and MBeans. Here is a short note.

- Download JMXterm
https://sourceforge.net/projects/cyclops-group/files/jmxterm/1.0.0/jmxterm-1.0.0-uber.jar/download

- Run JMXterm
java -jar jmxterm-1.0.0-uber.jar --url localhost:<jmx listen port>

- All MBeans from java.lang
$>domain java.lang
