Understanding the kind of thinking that lead to the creation of object-orientation should assist in this cause. The thinking behind object-orientation is actually based on the recursive idea “that everything […]
When I was in elementary school, I sat in the front row of a Lance Burton magic show. It was quite entertaining, and I, along with the rest of the audience, was amazed at the magic tricks he performed. At one point in the show, he looked around for a kid, spotted me, and asked if […]
“Captain. I have a visual.” “What’s the status?” “Just one mutant bug, sir.” “Ha! What can one bug do to our company? Destroy it.” A tank round was fired in the bug’s direction. “Good shot.
