Rate of contributions accelerating: what the commit messages say ...

There's some slightly weird data in there: commit 1000 was in July 2003, and commit 2000 was in April 2001. Commit 3000 was in 2004, and commit 4000 was back in 2003.

However, other interesting statistics:
- In 2005 it took about a month for each thousand commits, now it takes 4-5 days.
- Even at the start of 2008, this was 8 days

<?php
$n = 0;
print "date,commit\n";
while ($n <= 150000) {
  if (preg_match('#<h3>(.*) (.*), (.*)</h3>#', file_get_contents('http://drupal.org/cvs?commit=' . ($n+=1000)), $bits)) {
    print "$bits[2] $bits[1] $bits[3],$n\n";
  }
}
?>
