2 ways to extract elements from within XML namespaces using Nokogiri
When trying to select elemenets in the default namespace, e.g. "xmlns= http://www.w3.org/2005/Atom", try the following two ways. Note the xmlns=" attribute on entry element:

Original xml:
Nokogiri::XML(@xml_string).xpath("//author/name").each do |node|
    puts node
  end


1. Define a namespace context for your XPath expression and point your XPath steps to match elements in that namespace. Define a namespace-to-prefix mapping and use this prefix (a) in the XPath expression.

Dear Rubyists,

I just lost a contract because of my code in a Rails project.

The specific code in question is related to a "posting a comment" feature. Here are the details:

In this project, "posting a comment" does not simply entail inserting a row into the database. It involves a procedure to yes, insert a row, but also detect its language, check for spam, send emails, and "share" it to Twitter and Facebook. I believe this algorithm should be encapsulated. I do not believe it belongs in a controller or a model. I do not believe Active Record callbacks should be used.

The "senior developer", whom is the stake holder's right hand man, said this:

Follow the instructions here: The Hitchhiker's Guide to Riding a 
Mountain Lion http://j.mp/Qm5UJD, including installing XQuartz.

After installing XQuartz set the correct path to the X11 library to 
install Ruby 1.8.7-p358 with rbenv:

  export CPPFLAGS=-I/opt/X11/include

then let the compiler know where gcc-4.2 is:

#   ~/Library/Rime       (macos)
