Providing guidance (and some example code) in mentoring a new developer in Ruby, I threw together this little sample that calls upon my BusinessSpew API.

bs.rb

require 'net/http'  #including external libraries
require 'json'

URL = "http://bs.leveragedsynergies.com/api"  #Constant definition

#TODO: params can be extracted from input on the command line    <== and example of a comment
params = { paragraphs: 2, sentences: 4, title: 'Daily BusinessSpew Report' }  #Ruby hash for set of parameters


uri_string = URI.escape("#{URL}/#{params[:sentences]}/#{params[:paragraphs]}/#{params[:title]}")  #illustration of Ruby string interpolation
uri = URI(uri_string)
request = Net::HTTP.get(uri)  #call to "class method" (in external library)
bs = JSON.parse(request)

title = bs['title']  #manipulating JSON
paragraphs = []   #assignment of a variable in order to establish its scope

bs['paragraphs'].each do |p|   #common Iteration AND Ruby Block
  paragraphs << p  # "shovel" shorthand (syntactic sugar)
end

puts "#{title}\n#{'=' * (title.size)}\n\n"    #the common 'puts' statement and more string interpolation
puts paragraphs.collect{ |p| ["\t#{p}\n\n"] } #common ruby iteration operation (inline block)
puts           # empty 'puts' provides blank line
puts

This could be easily enhanced to accept input parameters (using the Ruby hash.merge! command. I will resist the strong temptation to modify this and leave that as an exercise for you - the reader.
