10.4: See multiple feeds over time in RSS screen saver
Authored by: t7p0m8st3r on Jun 01, '05 06:22:13AM
I whole-heartedly agree. My implementation in the original script was lousy. Thanks to other .plist hints, I did discover that my code was not an efficient way to go. I re-wrote the script and sent it in, but I guess it got separated from the original hint. This version starts with a different feed in the list each day, to get a little extra rotation into the mix. Here it is, if you're interested:
#! /usr/bin/perl -w
# SS-RSS_rotate.pl
# release version 2.0
# May 17, 2005
# rick@aveight.com
# Rick Smith
# VERSION HISTORY: removed to be concise
# rotates RSS Screensaver by hour, and starts with different RSS each day.
# rotation may jump unpredictably on first day of each new year.
