There's no I in Interface

I'm refreshing my memory about software design patterns by watching some videos and taking some notes. I thought I would document them here for future posterity. These are the design patterns as defined by the Gang Of Four (GoF) in their seminal book "Design Patterns: Elements of Reusable Object-Oriented Software" and can be found on Amazon (non-affiliated link) .

My first job - not even out of high school - was detasseling for the regional farmers through the local coop. Now, I grew up in Iowa, so there's a fair amount of things I need to explain, but let's just cut to the chase and say that all you've ever heard about Iowa is probably true. Corn. It's everywhere. Pioneer was a major business in them parts, and they had enough capital to make it worth your while to work in the heat of the Iowan summer walking miles through paper-cutting corn leaves to make a buck.

A couple summers of that work, though, and one might reflect on their current situation and aspire to some
