That's what's happening on that page. As people edit Wikipedia,
information about their updates is logged to this page
http://en.wikipedia.org/wiki/Special:RecentChanges
Laszlo has a chron job that reads that page every 3 minutes looking for
entries by anonymous users (because Wikipedia exposes the IP address
only for anonymous users) guesses the user location from the IP address
and stores the last 30 in his own database.
When you run http://www.lkozma.net/wpv/newest2.php?lastid=12345, it
scans that database and returns a list, starting at the specified lastid
if that's within the range held in the database.
The data at http://en.wikipedia.org/wiki/Special:RecentChanges is
changing all the time, so the data returned by newest2.php is dynamic,
rather than being a static XML file that changes only when updated by
the author.
