Am I doing it wrong?

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:

More technical details about the discussion at last nights meetup
# Just wanted to clarify my points at the meetup last night.
#
# There were two different issues intertwined:
# (1) Whether to use extend or "include as extend"
# (2) When using "include as extend", what is the simplest way to achieve the goal?
#
# My personal opinion is that the answer to (1) is "extend", not "include as extend", but that
# is just my personal opinion. My answer to (2) is a more empirical question.
# Using the "extend" approach. Again, I personally prefer the simplicity of this approach, but

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
