Subject: Default parameters? + (Noob) Guidance

Hi guys, would love your help with a few questions:

1) working on the RubyMonk.com primer.
It's pretty good, but it got vague and super challenging all of a
sudden. (or maybe i just got dumb.)

This is where I am stumped:

     def say_hello(name)
         "Hello, #{name}."
     end

The output:

     returns "Hello, Master." when say_hello("Master") is called ✔
     Error: returns "Hello, Qui-Gon Jinn."
     when say_hello is called with no parameters
          Error: wrong number of arguments (0 for 1)

The question:

How do I write a default value, to account for when the object is called
with no parameter?? I feel I've tried everything: googling/ testing,
re-reading
rubymonk/ testing, rereading ruby doc/ testing; can't get it!

The link:

http://rubymonk.com/learning/books/1/chapters/19-ruby-methods/lessons/69-new-lesson

Help!

2) in moving forward, how would you recommend I teach myself?
     a. Michael Hartl's tutorials? or perhaps
     b. Chris Pine's PragProg book: "Learn to Program"?
