If you come from math, you should know that “orthogonal” means “independent” in statistics and linear algebra. https://en.m.wikipedia.org/wiki/Linear_independence https://math.stackexchange.com/questions/1536234/correlation...

It means perpendicular in geometry. But perpendicularity implies connection, and therefore, dependency. Your links barely prove anything? I already knew that statistics is a fictional field.

Sorry, but now I highly doubt that you have any background in math. That's just a non sequitur.

Why is "opinionated" considered so valuable these days? In this case, it's redundant (curated implies opinionated, I think), so it's there to say something loudly. What? Are people not being opinionated enough? Is this defensiveness (if someone doesn't like what you did, well, you've already said it's just your opinion, man)?

I see it as a disclaimer: "I don't claim this to be the best thing applicable to everyone. I have strong opinions that some people don't agree with and this list doesn't include some things other people's lists would."

In contrast there are some list which claim to be comprehensive.

You’re using an overly narrow sense of the term in math.

Consider any orthogonal coordinate system (https://en.wikipedia.org/wiki/Orthogonal_coordinates). The whole point of orthogonality in this case is that it makes coordinate values independent of each other - varying only one coordinate cannot result in a change in any other coordinate. The term is used in this same sense in many other areas of math, and elsewhere. This is the sense in which it’s been used in software, for more than half a century.

Forgive my curiosity, but in what sense were you “originally from math” but aren’t familiar with this term beyond a high school level understanding of geometry?

It's yet another funny trend that goes around in tech circles. As someone originally from math, my personal pet peeve is the way that tech people use "orthogonal" these days. I guess people just want to communicate the idea that this piece of opinionated text is biased. Of course, everything is biased, so opinionated is supposed to be redundant. So it's a signal that the author understands that they have biases, and…

> the way that tech people use "orthogonal" these days. If you mean the sense which means “independent”, that goes beyond tech. It was used that way by a law professor in front of the Supreme Court in 2010: https://www.abajournal.com/news/article/supreme_court_word_o... In software, its use in that way dates back at least 30 years. E.g. from https://www.sciencedirect.com/science/article/abs/pii/016560... (1992): > It…

Possibly the first published use of the term in software was Van Wijngaarden, in the design of Algol 68, from 1968:

> The number of independent primitive concepts has been minimized in order that the language be easy to describe, to learn, and to implement. On the other hand, these concepts have been applied “orthogonally” in order to maximize the expressive power of the language while trying to avoid deleterious superfluities.

Good explanation!
