I cannot understand what you're trying to say at all.

Ok but no one here actually implied that they think like this.

YouTube already supports that natively these days, although it's kind of hidden (and knowing Google, it might very well randomly disappear one day). Open the description of the video, scroll down and click "show transcript".

In that case, how come they "left in the first days of the job" because "they saw what they were going to work on and peaced out"?

I seriously doubt saying "big blond haired baby who likes burger and fascism" instead of "Trump" would have made a difference for these people.

No, it's both.

The purpose of high school is to give you a wide foundation on everything.

The purpose of an undergraduate degree (in math) is to give you a wide foundation (in math).

In a (math) PhD, you are generally hyper-specialized in a very, very narrow area (of math).

No, and this is where this formal notion of basis I mentioned unfortunately diverges from what is perhaps more useful in practice.

You can represent any function f: [-pi, pi] -> R as an infinite sum

    f(x) = sum_(k = 0 to infinity) (a_k sin(kx) + b_k cos(kx))

for some coefficients a_k and b_k as long as f is sufficiently nice (I don't remember the exact condition, sorry).

This is very useful, but the functions sin(x), sin(2x), ... , cos(x), cos(2x), ... don't constitute a basis in the formal sense I mentioned above as you need an infinite sum to represent most functions. It is still often called a basis though.

The set of all real->real functions is still a vector space.

This vector space also has a basis (even if it is not as useful): there is a (uncountably infinite) subset of real->real functions such that every function can be expressed as a linear combination of a finite number of these basis functions, in exactly one way.

There isn't a clean way to write down this basis, though, as you need to use Zorn's lemma or equivalent to construct it.

> This might be okay for consumer apps, but maddeningly, the same doctrine gets applied to enterprise applications as well. I've literally heard non-techie employees of a Fortune 100 company ask for their legacy green screen terminals back because the new, flashy SPA was slowing them down.

Applying general design principles without taking actual use cases into account is the worst.

A common one is putting heaps of whitespace around each cells in a table. Visually appealing, sure. But unusable if I need to look at more than 8 rows at the same time.

I feel like this is kind of pedantic - if your definition of the word "political" renders their point moot, then clearly they must be using a different definition.

But I understand what you mean. The problem is that 99% of online discussions about politics are not about how it relates to anything else. They are usually the same 5 conversations rehashed over and over again. And for some reason, they are aggressively derailed in that direction.

I once had to solve a captcha in a foreign language because of that. Wasn't something obvious like motorcycles either, it was something like "click on all hamsters" in a grid full of various rodents.

I suppose the point is that it's not the voiceless glottal fricative?

To my ears [ħ] sounds closer to [x] and [χ] than to [h] (even though the place of articulation is closer to [h]), but I'm sure it's different for people who (natively) speak a language with all three.

> FluffyChat, Nheko, Cinny are all great fully featured apps and separate codebases

Ok, I was mistaken about everything being an Element fork.

To move the goalposts slightly though --- do any of these apps properly support threads (i.e. messages in threads show up in and only in separate views)?

My team uses Matrix and I must say I'm not satisfied. There are messages that I get a notification for every time I open the app, and "mark as read" buttons that do nothing, especially if you use threads. This is something that has supposedly been fixed many times, but it's one of these persistent issues that keep coming back.

Also, as far as I can tell, there is no real diversity in clients even though Matrix is in principle an open protocol. Everything is either Element or a fork of it, or at least is built on matrix-react-sdk, which makes them all effectively the same.

I'm not saying you're wrong, but I wonder if this "missing piece of insight" is at least sometimes an illusion, as in the "monads are like burritos" fallacy [0]. Of course this does not apply if there really is just a missing fact that too many explanations glossed over.
