Obligatory "this painting is a mathematical formula, a big function on the x and y coordinates of each pixel" video from Iñigo Quilez. https://www.youtube.com/watch?v=8--5LwHRhjk

The one where he does a landscape is one of my favourite videos of all time.

It's the same for me when foo and bar are used as examples.

Someone gave me the advice to use animals, ideally animals of very different sizes or colours. People instantly picture them and remember them.

The alternative I'd suggest to someone using Hugo for a simple site/blog would be https://www.getzola.org. Single binary, batteries included.

Does anyone have a better go to?

This is what I use and I’ve been very happy with it for many years. It hasn’t caused me any trouble and as far as I can tell it hasn’t changed in the whole time I’ve used it.

This article and its associated HN comment section continue in the long tradition of Big O Notation explainers [0] and getting into a comment kerfuffle over the finer, technical points of such notation versus its practical usage [1]. The wheel turns...

Hehe, yes, Ned sent me a lovely email the other day about it. Happy to be doing my part.

Most people from almost every specialty mostly dismiss calculus as useless, don't even remember linear algebra is a thing, and never learn or forgets everything about statistics. (But the reaction to probability varies a lot.)

I have no idea what's up with those disciplines, but it's an almost universal reaction to them. Unless people are very clearly and directly using them all the time, they just get dismissed.

Can’t imagine what it might be.

Given the various ways people in this thread have pointed out you lack fluency with the notation, why do you think it reasonable for people to want to learn it without learning the concepts it's describing?

I’m not sure that’s quite my position. Happy to cede that I lack fluency, and I appreciate your time and the time others have given to help me understand.

I would just say "almost always" to cut off the pedants. You do use the same notation to describe the best-case and average-case as well; people just don't care about those as often.

I did push up a rewording that hopefully lands better. Fingers crossed.
