How do I remember that the HTML named entity for an ellipsis is
… and not
&ellip;? Because if it were ellip, for ellipsis, I wouldn’t be wondering in the first place about whether or not there’s an “h” in there. (It’s a horizontal ellipsis.) (There’s also a vertical ellipsis numbered entity.) Though the exact definition of the Binary Borgnine Horizon System is as hazy as its name, it’s basically that you should look for ways to reduce in two steps — first to a binary, then between the two. That there’s a good number of these easy-level Sudoku puzzles sitting around in life.
Argentina and Venezuela are another example. How do I remember that Venezuela is at the top of South America and Argentina is at the bottom of South America? I happen to have noticed once, in elementary school, that they started with letters at opposite ends of the alphabet. Only I found it a shame that the letters were switched around in order, because I needed to remember it as A to V. Top to bottom — the Western text direction other than left-to-right. Then I realized that, because I happen to know that they’re switched around, it can only be the one way. In other words, because I already knew about that first letter thing, I had a binary. Understanding that there was an extra step involved meant that it couldn’t be the original way. It filled in two more countries in my image of South America, and I could avoid learning by rote.
The Borgnine Horizon, by the way, is the point beyond which all is Ernest Borgnine. There’s no actual idea attached to that.
