Windows 7 editions
Did you know there's an entire article on Wikipedia about the various Windows 7 editions? Talk about confusing.

RhythmToWeb moved to Google Code
I have moved the RhythmToWeb project to Google code. Apart from a small bugfix (it used to send empty requests every x seconds when Rhythmbox was first started), I have also added a couple of server-side examples.

Apache nice URLs without mod_rewrite
I recently noticed a peculiar behavior in Apache. It seems that if I have, for example, a file
The only situation I can imagine where you would absolutely need
/var/www/hello.php, the following URLs will load the same file:
- http://localhost/hello.php
- http://localhost/hello
- http://localhost/hello/goodbye/
The only situation I can imagine where you would absolutely need
mod_rewrite is if you need to have URLs like http://example.com/1234, you can't handle that with MultiViews (but you can handle http://example.com/article/1234).

RhythmToWeb Updated
I've recently received an e-mail from Aaron Hill, about some modifications he's done to RhythmToWeb. I took his idea of storing information about more than one song, and adapted it in my own way. You can now use the buttons under the song information on the right to browse the last 5 songs I've played. It will also automatically refresh, so if you wait around long enough you'll see it switch to a new song when I start playing one (I really don't know who I'm kidding, no one will ever wait on my blog to see when my song changes :P). Anyway, on to the code:
PHP, this gets called by Rhythmbox:
<?php
define('CALLBACK', 'rtw_callback');
define('JS_FILE', 'nowplaying.js');
define('MAX_ENTRIES', 5);
define('SERIALIZE_FILE', './data');
function test_value($var) {
if ( strlen($var) && mb_strtolower($var) != 'unknown' && $var != '0' ) {
return true;
}
return false;
}
$song_info = array();
foreach ($_GET as $key => $value) {
if (test_value($value)) {
$song_info[$key] = $value;
}
}
$last_songs = unserialize(file_get_contents(SERIALIZE_FILE));
if ($last_songs === false) $last_songs = array();
elseif (count($last_songs) >= MAX_ENTRIES) {
while (count($last_songs) >= MAX_ENTRIES) {
array_shift($last_songs);
}
}
$last_songs[] = $song_info;
file_put_contents(SERIALIZE_FILE, serialize($last_songs));
file_put_contents(JS_FILE, CALLBACK . '(' . json_encode($last_songs) . ')');
