in reply to Custom-length random/unique string generator

A minor point:

From the Camel Book (4th Edition, 2012, page 695), under the heading “Time Efficiency”:

  • If you’re deleting characters, tr/abc//d is faster than s/[abc]//g.

So, if speed is a limiting factor, consider replacing:

# Strip out "+" and "/" $buildID =~ s/\+//g; $buildID =~ s/\///g;

with:

$buildID =~ tr{+/}{}d;

Hope that helps,
