13 years ago today, the first version of what became PHP Network Weathermap was released… it was a series of versions in Perl, adding functionality to the GRNET Weathermap. After a few of those, and getting tired of explaining how to build CPAN modules, I started re-writing the whole thing in PHP, initially before the Cacti Plugin Architecture existed, as a standalone script sometime in April 2005. Sadly, it looks like the Cacti Forums have had some database corruption over the years, so posts that old seem to be missing.
