Setup Mac OS X

Edit: I've done the same process every couple years since 2013 (Mountain Lion, Mavericks and High Sierra).

I just replaced the hard drive of my mbp and decided to do a clean install of Mountain Lion (10.8.5) since I was still using Snow Leopard (10.6.8).

I kinda regret for not using Boxen to automate the process, but TBH I have this laptop for almost 3yrs and this is the first

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.

# Okay lets first implement the base cases and then we can tackle higher numbers
# First we need to have the condition thats stops the sequence, i.e when n is 1

while(n != 1) do
  # the sequence here
end

# Now for the rules to be implemented
# n → n/2 (n is even)
# n → 3n + 1 (n is odd)
