Hello ruby friends,

Next Tuesday night is Seattle.rb's monthly talkie meetup! Things will be going as planned with one big exception: 
Ryan, Aja and I will all be travelling to Mountain West Ruby Conf that night. Don't worry though, two of my Substantial
coworkers have offered to host in my stead. Cassie Schmitz and Shawn Dempsey will be the ones who will let you in the door, 
tell you the wifi password, direct you towards the restrooms and urge you to leave at the end. Everything else will be the 
same, although I cannot promise you'll hear another of Aaron's thrilling tales of candy purchasing.

Let me know if you have questions or concerns!

Failures:

  1) Hash #=~ displays confusing error message when hashes are equal
     Failure/Error: actual.should =~ actual
       expected: {:foo=>"bar"}
            got: {:foo=>"bar"} (using =~)
       Diff:{:foo=>"bar"}.==({:foo=>"bar"}) returned false even though the diff between {:foo=>"bar"} and {:foo=>"bar"} is empty. Check the implementation of {:foo=>"bar"}.==.

One that seems to surprise a lot of people is Hash.from_xml:

 > hash = {:foo => 'bar', :baz => 'qux'}
 => {:foo=>"bar", :baz=>"qux"}
 > hash.to_xml
 => "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<hash>\n
<foo>bar</foo>\n  <baz>qux</baz>\n</hash>\n"
 > Hash.from_xml(hash.to_xml)
 => {"hash"=>{"foo"=>"bar", "baz"=>"qux"}}
