in thread Zipcode Proximity script

At which point you're into a lot more complexity. If you're going to pre-generate that much data, just build a data set for each state that includes all zips within the greatest possible search radius, and start each search with the right data set.

    For the data set I was working with it really was no complexity at all. It certainly isn't the biggest reduction of the data but it's a fairly quick reduction to do. You could certainly partition it better but this was a quick and dirty way to do it that worked for my application.

[ambrus]: Corion: what I don't understand is, if you make a one-shot AnyEvent timer with short timeout, does this code guarantee that the Prima timer can't queue two timeout events before invoking any of them?
[ambrus]: Because that could break AnyEvent code, which is why I added a guard.
[ambrus]: (It might be easier to use the callback scalar as a guard, as in $c and &$c(); $c = ();)
[Corion]: ambrus: Hurr - yes, that might happen, as Prima will queue lots of stuff (Well, Windows will)
[Corion]: But I'm really amazed that it just took this little code (plus the idle handler I have in mind and something else dk suggested)
[Corion]: ambrus: I wrote the handler so that it stops the timer if it's supposed to be a one-shot
