The music clock is an invisible clock. It tells the time through musical
tones. For now, it reads the hour and the minutes mod 12. Hopefully I will be
able to explore this idea and come up with a universally understandable and
recognizable system.
I use ajax requests and ruby and sox on the backend to make this work.
Now that nobody burns CDs for each other, lately when making mixes I go through a painful process:
I set and found a few applescripts to handle automating one or two of the above tasks, but I thought I might as encapsulate the whole thing. So here’s my solution as an applescript:

Copy selected tracks and re-add into itunes with album = to given text and track numbers according to selection order

-- check if iTunes is running
tell application "System Events"
if (get name of every process) contains "iTunes" then set okflag to true
end tell

display dialog "Select some tracks first..." buttons {"OK"} default button 1
else

set number_of_tracks to length of selected_tracks

I previously posted a bash script to count and print plain text and html listings of a directory: intended for displaying audiobook and music libraries. I recently tried to use the bash script on a large directory and it stalled because sed can’t handle large input. Here’s a ruby version that does the same thing:
#!/usr/bin/ruby -w
usage = "Usage: list [filename] [directory]
If filename ends with .html then output will be html,
else output will be plain text."
if not ARGV[0] or not ARGV[1]
puts usage
elsif not File.directory? ARGV[1]
puts "list: #{ARGV[1]} is not a directory"
puts usage
else
dir = ARGV[1]
# should be quoted?
plain = (`ls -1 "#{dir}"/*`+"\n")
if(ARGV[0] =~ /.html$/i)
plain = plain.split("\n")
author_count = plain.find_all{|line| line=~/:$/}.length
title_count = plain.find_all{|line| line=~/[^:]$/}.length
body = plain.collect do |line|
line.gsub(
/(.*)([^:])$/,' \1\2</br>').gsub(
/^\s*$/,' </div>').gsub(
/.*\/(.*):$/,' <h3>\1</h3>'+"\n"+' <div class="books">')
end
output = "<html>
<meta http-equiv='Content-Type' content='text/html; charset=UTF-8'/>
<head>
<style type='text/css'>
body {
font : 10pt verdana;
background: white;
width: 95%
}
h2 {
margin: 15px 0px 5px 0px;
}
h3 {
margin: 15px 0px 5px 0px;
}
.books {
border: 1px solid #dddddd;
padding: 5px 5px 5px 10px;
background: #eeeeff;
}
</style>
</head>
<body>
<h2>#{title_count} titles and #{author_count} authors</h2>
#{body.join("\n")}</div>
</body>
</html>"
else
output = plain;
end
File.open(ARGV[0], 'w') {|f| f.write(output) }
end
I’m reposting the mashup track, “Jaw Disorder, Women All in Tents” by Detective Defenstrator, featuring Quasi, the Gorillaz, Vincent D’Onofrio, Kathryn Erbe, Robert Knepper, and K-Ci & JoJo.
I gave up using iTunes to play music about year ago, but I haven’t found a free alternative to iTunes’s exceptional file management based on mp3 ID3 tags (If you know of one — I mean better than iTunes one — let me know). So occasionally I let iTunes organize my music library. I drop in folders containing new music and let iTunes go at it. The problem is that if I have folders containing an mp3 and an m3u playlist I get duplicates. If I don’t notice this right away the duplicates build up.
Here’s a bash script to delete all true duplicates. The files must be exactly the same and have almost the same name (the difference being the number iTunes appends on a copy: “song.mp3″ becomes “song 1.mp3″).
Verbose version:
#!/bin/bash
find "$1" -regex ".* [0-9][0-9]*\.[^.]*" -print0 | while read -d $'\0' copy
do
original=`echo "$copy" | sed "s/\(.*\) [0-9][0-9]*\(\.[^.]*\)/\1\2/"`
# check that the hypothetical original exists
if [ -e "$original" ];then
# check that the original is exactly the same file as the copy
if diff "$original" "$copy" >/dev/null ;then
rm "$copy"
echo "$copy deleted..."
else
echo "$copy is different..."
echo " $copy not deleted..."
fi
else
echo "$original does not exist..."
echo " $copy not deleted..."
fi
done
Quiet Version
#!/bin/bash
find "$1" -regex ".* [0-9][0-9]*\.[^.]*" -print0 | while read -d $'\0' copy
do
original=`echo "$copy" | sed "s/\(.*\) [0-9][0-9]*\(\.[^.]*\)/\1\2/"`
# check that the hypothetical original exists
if [ -e "$original" ];then
# check that the original is exactly the same file as the copy
if diff "$original" "$copy" >/dev/null ;then
rm "$copy"
fi
fi
done
