A python script for extracting email addresses from text files.You can pass it multiple files. It prints the email addresses to stdout, one address per line.For ease of use, remove the .py extension and place it in your $PATH (e.g. /usr/local/bin/) to run it like a built-in command.

How to proxy web apps using nginx?

Virtual Hosts on nginx (CSC309)

When hosting our web applications, we often have one public IP address (i.e., an IP address visible to the outside world) using which we want to host multiple web apps. For example, one may wants to host three different web apps respectively for example1.com, example2.com, and example1.com/images on the same machine using a single IP address.

How can we do that? Well, the good news is Internet browsers

Step by step guide to install nominatim server
I followed these two blogs to install server
1. http://koo.fi/blog/2015/03/19/openstreetmap-nominatim-server-for-geocoding/#Compile_Nominatim
This explains ( and is the main blog which I followed) various steps
2. https://www.linuxbabe.com/linux-server/openstreetmap-tile-server-ubuntu-16-04
This explains how to setup swap files and install tiles if needed.
I will use Ubuntu 14.04 LTS as the platform. Just a basic install with ssh server. We will install Apache to serve http requests. Make sure you have enough disk space and RAM to hold the data and serve it efficiently. I used the Finland extract, which was about a 200 MB download. The resulting database was 26 GB after importing, indexing and adding Wikipedia data. The Wikipedia data probably actually took more disk space than the OSM data. My server has 4 GB RAM, which seems to be enough for this small data set.
