Subject: Re: comparing objects

The first solution sent by Marcin Wolski works for normal ruby classes, 
but I got something wrong when using with an ActiveRecord class. I am 
not sure about the problem know.

So I tried Robert Klemme's solution, using:

in_both = obj_from_db.select do |u1|
   obj_from_xml.any? do |u2|
     u1.email == u2.email && u1.age == u2.age
   end
end

That's working know.
I have to study a little more of your suggestions since this aproach 
still looks like slowly yet....

To figure the problem, I am using this algorithm at 
http://www.dobbyme.com

That's a birthday reminder. The idea implemented here is: I got your 
gmail contacts (useim gdata gem) and lokk at dobbyme's database to match 
if you have some contact already registered.

I think now the actual aproach is fine, but with a lot of users I will 
start to have some troubles...am I right ? Opnions ?
