Hi all,
I'm slowly getting settled in at Cambridge, and as a warm-up I hacked a little JavaScript that might be an alternative to the CheckUsage script. Demo at:
http://tools.wikimedia.de/~magnus/commonsusage.html
It runs through a combination of project types (currently wikipedia, wikibooks, wikinews) and languages (currently en, de, es, fr, pl, it, sv), and queries the usage of an image through the API, which is always up-to-date. Enter an image name and click "Search", and you can see the list getting shorter as queries are completed (or longer if there are many hits); IMHO this cuts down on the "subjective waiting time" ;-)
Two drawbacks to this: * It hits the API, which might slow things down if used large-scale * Due to JavaScript security limitations, I have to go through a Perl script on the toolserver for each query (ugh!)
However, it might be an in-place alternative to Duesentrieb's script if installed on commons. Note that the perl script would also have to be on commons.
