An irregularly updated journal of my Fair and Balanced thoughts, reactions, opinions, biases, outrages, strategies, victories, and commentary. Whatever it is, it's much too subtle to be considered a parody...
While before I was getting in over my head, now I think I have the right solution for Trackbacks. I will write a hack that causes MT to check for an existing trackback to my URL and not send a duplicate ping. It should be as simple as getting the trackback RSS feed, searching for the <link>http://myserver/mypath/myfile.html</link> that I'm about to send anyway, and not pinging if the site reports I've already sent it.
My only design question is 'should it resend if the excerpt changes?', and that's something I can think about. It should be a relatively small hack, since all the tools are already there.
