As a Perl programmer and someone who is exploring open source alternatives for video surveillance, I cam across a show on the Floss Weekly netcast hosted by Randal Schwartz -- a leader in the Perl Programming community. See https://en.wikipedia.org/wiki/Randal_L._Schwartz. Randal is the author or co-author of several leading books about Perl published by O'Reilly: https://www.oreilly.com/pub/au/335 I've used his books extensively and was delighted to learn of his hosting role in Floss Weekly.
Here's his 1 hour broadcast about Zoneminder:
For what it's worth, I've been exploring a recent upstart project, Shinobi, as it sports features that I'd like to have in Zoneminder and I felt that Zoneminder might be languishing. (I have not finished watching this netcast, I wanted to post here while I remembered.)
