CGI script that will stream files from my ~/Music directory
#!/usr/bin/env php
<?php
/*
* This is a terrible way to build a streaming server as a cgi script! It
* takes a song from a query string, checks for its existence in the

#!/usr/bin/env bash
# Meant to be run in a git directory
# This gets the first 12 bytes of a .git/index file which according to the spec (https://github.com/git/git/blob/master/Documentation/technical/index-format.txt) are:
# - 4 byte signature
# - 4 byte version
# - 32-bit (4 byte) number of entries, i.e. number of files
#
# This will pass the final 32-bits off to python to unpack a NBO Long to show the number of entries
