As developers get started with a project, they prefer having total control over the development environment, as much as possible to perfectly match the deployment environment. The other strong requirement, especially in a team with mutiple developers would be to work on exactly replicated environments.
When developers shift from PHP, Ruby or any other platform to Python, the very first road block they face (most often) is a lack of an overall understanding of the Python ecosystem. Developers often yearn for a tutorial or resource that explains how to accomplish most tasks in a more or less standard way.
What follows is an extract from the internal wiki at my workplace, which documents the basics of the Python ecosystem for web application development for our interns, trainees and experienced developers who shift to Python from other platforms.
So, you have a binlog. You want to find out something specific that happened inside of it. What to do? mysqlbinlog has some neat features, which I thought we would look at here.

The stub_status module provides the ability to get some stats from nginx...
active connections -- number of all open connections including connections to backends
server accepts handled requests -- nginx accepted connections, handled connections (no one was closed just it was accepted), and handles requests (requests per connection = handles requests / handled connections)
reading -- nginx reads request header
writing -- nginx reads request body, processes request, or writes response to a client
waiting -- keep-alive connections, actually it is (active - reading + writing)
