I'm sure there are specific programs that would benefit from a treatment from these rules. However, there's one thing pretty fundamental to this article that I have a hard time agreeing with. And that is the notion that there are these three different memory types, two of which can only store "4 to 6" things. I'm inclined to believe that there are probably many gradations of long vs. short term memory in the structure of the brain. In fact, I bet the gradations even vary by topic and of course depend on what sorts of tasks a person is accustomed to performing from day to day. I imagine that the "4 to 6" figure fell out of a study that aggregated a large amount of data collected across subjects and that the figure itself can't capture much of the nuance or even the nuance of cohorts. In other words, it may very well be that a large percentage of people who work professionally as software developers are capable of keeping more than 4 to 6 "facts" about code they're looking at in their head. But that they would also appear to have the same capacity as random people when it comes to arbitrary facts that one would be asked to memorize in a psychological study.
