As you can do with UserTalk scripts in Radio UserLand, you can write scripts that enhance the functionality of Movable Type. The software can be extended with Perl scripts that are executed by placing HTML-style tags and attributes in templates, the same technique employed by the software itself. The script output appears in the rendered file.
Plug-ins also can filter text on any Movable Type template tag. I wrote one this afternoon that tackles an obnoxious form of comment abuse: Posting a bogus comment packed with spam links.
The RemoveExcessiveLinks filter sets the number of links you're willing to tolerate in a user-submitted comment. When a comment hits or exceeds the number, all links are removed from the comment.
To use it, place the RemoveExcessiveLinks.pl script in Movable Type's plugins directory. Use it with a tag by adding a remove_excessive_links attribute with the number of comments to trigger your wrath, like so:
<MTCommentBody remove_excessive_links="5">
With this example, any comment with five or more links will be sanitized to remove all of its links.
I subscribed to XM Satellite Radio during the trip, stopping at a Wal-Mart in Live Oak, Florida, to buy a Delphi SkyFi receiver.
The Jetsons future has arrived. I set up XM service with a cell phone and credit card as we drove down Interstate 10, placed an antenna smaller than a floppy disk on the dash, and began receiving 230 stations within 30 minutes.
I bought the radio to free myself of the need to maniacally hunt for stations as they dropped in and out of range on the road trip. Though I got it primarily for Sporting News Radio (how could the Lakers trade Shaq?), the most useful channel turned out to be Open Road, a truckers' radio station that offers frequent interstate weather reports.
Because of Open Road, we avoided storms on I-10 coming home, stopping for the night in Biloxi, Mississippi, when they reported thunderstorms from Alabama to Jacksonville. Driving at night on a highway full of trucks and tired travellers always makes me think about Jayne Mansfield. And not in a good way.
Open Road's a fascinating example of a community forming out of thin air. More than 70,000 of XM's one million subscribers are truckers, according to Truck.Net, and callers, who are primarily long-haul truckers, talked about road conditions, kvetched about concerns such as the law that forbids idling trucks overnight to keep with the air conditioning on, and discussed the need to organize politically. It felt like an 18-wheeled MetaFilter.
