I've removed advertising from most of this site and will eventually clean up the few pages where it remains.

While not terribly expensive to maintain, this does cost me something. If I don't get enough donations to cover that expense, I will be shutting the site down in early 2020.

Perl script to get Numly

Following up on Numly tags help protect your digital content, I wrote a Perl script to fetch Numly ESN's.

I have this script create a ".numly" file in the same directory as the original page; my page display code notices if that file exists and displays it if it does.

So, for example, to create the Numly data for this page, I'd run "getesn.pl http://aplawrence.com/Programming/numly_tags.html" and that will create "/Programming/numly_tags.numly" in the appropriate place.

I didn't put a lot of error checking in here, and of course you'd need to modify it for your own particular needs.

See LWP and POST and GET for more on using Perl LWP.
