>>7619780I am the originator of the post which you replied to.
I have never met 1 CS major who knew even what a Singleton was, let alone how to implement one.
I can only assume by your post that you have never worked on a large coding project? (a medium to large software company)
If you do not understand how important OOA is,
then my advice is to partner up with someone who does. (assuming you are a coder)
Not knowing OOA is a bit like walking into a basement with thousands of wires, entangled, and having to untangle them by hand... in the dark.
