If one wants to search for his or her activity at the IRC channel of Creative Commons, he or she can use 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.'<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.
