ubuntu16.04--在标题栏显示网速
有时感觉网络失去响应，就通过Ubuntu 14.04自带的系统监视器程序来查看当前网速，但是这样很不方便，遂打算让网速显示在标题栏，那样就随时可直观的看到。一番搜索尝试后，成功实现！同时也实现了CPU、内存使用率等的显示。
先来看下效果图：
效果真是挺好的！
之前需要通过deb包安装，现在可以通过添加PPA安装：
- sudo add-apt-repository ppa:fossfreedom/indicator-sysmonitor
- sudo apt-get update
- sudo apt-get install indicator-sysmonitor
终端执行： indicator-sysmonitor &，然后Ctrl+C就可以实现后台运行indicator-sysmonitor，看下图标效果，效果很不错！

But it is the same with man as with the tree. The more he seeks to rise into the height and light, the more vigorously do his roots struggle earthward, downward, into the dark, the deep - into evil.
其实人跟树是一样的，越是向往高处的阳光，它的根就越要伸向黑暗的地底。----尼采
