Re: converting hash to shuffled array

That's quite inefficient. Why not something like:

    my $key  = (keys %db) [rand keys %db];
    print "<a href = '$db{$key}'><img src = '/images/$key'></a>";

I gotta ask - where might be an explanation of the implicit int() within the subscripting []'s? It's so beautiful and dreadful at the same time. I've seen something like this done before, a long time ago, but I guess I just accepted it as 'magic'. I was reminded on CB that a FP number wouldn't make any sense as a subscript and so the DWIMish gnomes happily fixed the value. But sometimes I get this panicky feeling that if the magic isn't documented, it'll run away when I'm not looking.	[reply]
