In our product we have a big utilities file that we require (with do) at the beginning of a lot of our files. Is there a reason not to turn this into a module? For example, instead of doing this: do '../dbi_utilities.pl'; our ($db,$user,$pw,$attr); my $Data = DBI->connect($db,$user,$pw,$attr) or die "Could not connect to database: $DB...

It seems to me that all hashing does is storing information in semi-random positions in an array. I want to know how any of the data can be made useful after it's stored. My question is this: what are some examples where hashi...

Hi If you believe that a use case flow of events creates an actor, how would you model that? I have a use case that creates a windows service, which (in my mind) is another system with its own set of use cases and actors.

I don't understand what happens here : use PAR { file => 'foo.par', fallback => 1 }; I think that's an anonymous hash. How is a module using it from the use line? Can you shed some light? EDIT: I'm not interested in the PAR module. I'm just interested in how that works behind the curtain. How can I configure my modules like that? ...
