If one wants to search for his or her activity at [[IRC|the IRC channel of Creative Commons]], he or she can use [http://www.google.com/search?&q=john+site%3Ahttp%3A%2F%2Fmirrors.creativecommons.org%2Firc%2Fcc%2F Google] or the following public domain script written in PHP 5:
<source lang="php"><?php

$nick = 'john';
$path = 'http://mirrors.creativecommons.org/irc/cc/';
preg_match_all('/%23cc\.'.date('Y').'\-\d\d\-\d\d\.log\.html/', file_get_contents($path), $matches);
$irrelevant = array();
if (file_exists('irrelevant.txt')) {
    $irrelevant = unserialize(file_get_contents('irrelevant.txt'));
}
foreach ($matches[0] as $url) {
    if (file_exists('relevant/'.($filename = str_replace('%23', '', $url)))
     || in_array($filename, $irrelevant)) {
        echo 'Skipped ', $filename, PHP_EOL;
        continue;
    }
    $contents = file_get_contents($path.$url);
    if (!strstr($contents, $nick.'</th><td class="text"')) {
        echo 'Irrelevant ', $filename, PHP_EOL;
        $irrelevant[] = $filename;
        continue;  
    }
    file_put_contents('relevant/'.$filename, $contents);
    echo 'Downloaded ', $filename, PHP_EOL;
}
file_put_contents('irrelevant.txt', serialize($irrelevant));
echo 'Saved irrelevant.txt', PHP_EOL;</source>
Please note that the herewith enclosed script searches the logs saved the current year. All relevant logs are downloaded to the local machine.
