从源码编译 golang
首先下载 golang 的代码，可以从 https://golang.org/dl 或者中国的 mirror https://golang.google.cn/dl 下载最新的 go<version>.src.tar.gz. 然后开始编译就可以。
构建方法基本可以参考官方文档 就可以。

Go Proxy Configurations
To speed up our dependencies updating for golang, or prepare some patterns for our special libraries, we probably consider to use a proxy to speed it up.

The short-circuiting in bash
Bash script writing is a import approach to configure the linux system. Suppose we wish to add a user if not exists, the command may seems as follow:
TARGET_USER=alice
if (! id -u $TARGET_USER > /dev/null 2>&1 ); then
echo "creating user $TARGET_USER"
# adduser $TARGET_USER
fi
However, it is kind of too long. In this case short-circuiting is a alternative solution. (more…)

A simple workflow to create a clean python library based on Anaconda
The open-source Anaconda Distribution is an easy way to perform Python/R data science and machine learning on Linux, Windows, and Mac OS X. We could easily prepare an isolated and constant environment on anywhere based on a configure file.
Considering the various kind of strange errors due to the different versions of python and python libraries, this management tool makes our life much more comfortable in deploying and cooperating.

Gracefully shutdown a http server in golang
To gracefully shutdown a http server requires a few steps.
The http library's serving function will block over there when getting started, until we call http.Server.Close(). As for us, we can invoke the starting function in a goroutine, and call close in another one.
