HAProxy Config with ACL for Load Balancing Multiple Named Virtual Hosts
# Config ideal for load balancing many back-end Virtual Hosts with a pair of load balancers (one is for fail-over).
# HAProxy's ACL is ideal for dedicating more resources to certain virtual hosts especially to handle traffic spikes.
# Reference:
# http://www.techrawr.com/2009/09/18/using-the-acl-in-haproxy-for-load-balancing-named-virtual-hosts
# Don't copy blindly, change to suit your needs; at a minimum:-
# change maxconn based on your back-end server(s) capabilities
# enable/disable cookie option - disable if you don't want sticky sessions

Fetching lyrics in Unix

Fetching lyrics in the command line

Objective: Print the lyrics for the current playing song.

How: We'll create a small bash script to do the fetching for us (using curl) and then we'll display it either in the terminal or in our $EDITOR

Get the current song

First we'll need to get the name of the current song and its artist:
