The topic of `Category Mistakes,' which I have discussed in my four previous blog posts is not limited to digital systems. Engineers in all areas use models and they, too, can potentially fall into the trap of mistaking the model for reality.

Before really discussing category mistakes in computer science in follow-up posts, I will first continue testing my aforementioned categories on the writings of people I admire the most. I shall take a 2014 blog post, written by Michael Hicks in connection with the Heartbleed bug. (His post was written on July 1st, 2014 and I accessed it on September 19th, 2016.)

Before discussing several "category mistakes" in computer science in follow-up posts, it is much preferred to first introduce a few categorical distinctions and definitions and to subsequently test these concepts on the writings of computer science's greatests (i.e., the writings of the people I and many others admire the most).

(A comprehensive overview of my system later appeared in Science of Computer Programming [1]). Dr. X had already published his theoretical insights and he wanted me to incorporate his findings into my Ph.D. dissertation.
