A short article on git branching for new git users.

Branching with git for safe merging

Version Control is a critical tool in any software development project. Despite this, many of us suffer from a crippling fear of one terrifying event: The Dreaded Merge Conflict. Here I'll show you a risk-free way of merging with an easy way to back out if things go belly up.

c:\dev>git status
# On branch master

Practical Use of Docker

Docker is a useful abstraction for processes

  • Web application server (django/rails/tomcat/...)
  • Database
  • Reverse HTTP proxy (nginx/apache)

... each in their own Docker container
