Ubuntu Down Go language practice

This is a creation in Article, where the information may have evolved or changed. Go is an open source project with the BSD licensing agreement. The go language is the open source programming language that Google publishes.
Based on the trends in the IT world in recent years, I have learned to follow Google with meat, shame and then brave, to study the Google Genius 20% Project research and development of the new sharp language.
Next, get in touch with go and output the groundbreaking "Hello world!".
