This script is similar to:

ag pattern -l | xargs sed -i 's;pattern;replace;g'

with the added benefit that you can use proper regular expressions (e.g. grouping, lookaheads etc which are not supported on sed...).

Since ag is being used for searching the files, performance shouldn't be too bad (especially on SSDs).

How To Serve Flask Applications with uWSGI and Nginx on Ubuntu 14.04

Introduction

Flask is a microframework for Python based on Werkzeug, Jinja 2 and good intentions, it can help you get your Python application or website off the ground. Flask includes a simplified development server for testing your code locally, but for anything even slightly production related, a more secure and powerful web server is required.

In this guide, we will demonstrate how to install and configure some components on Ubuntu 14.04 to support and serve Flask applications. We will configure the uWSGI application container server to interface with our applications. We will then set up Nginx to reverse proxy to uWSGI, giving us access to its security and performance features to serve our apps.
