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

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 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.

You're right that discoverability is not really the issue.

However, I still agree with the GP that if you are not on the Play Store, you lose most of your installations.

If someone has already discovered your app and can't find it on the Play Store, they are more likely to assume that it's not supported on their phone, unavailable in their region or whatever. Even if you explicitly tell them to just download the APK, most people will not do that. Keep in mind that the average user probably doesn't even know that you can install apps from outside the Play Store. Or even if they guess that it's probably possible, they might well perceive it as complicated and sketchy.

As a customer of Kagi, it's better than the current Google but it's still not the Google of 2010. Google sponsoring irrelevant results is one thing, but the bigger issue remains: in 2024, creating a trove of worthless "articles" and optimizing the crap out of search result performance is a viable business model. Even if the SEO is done with mostly Google in mind, Kagi still picks up enough of this junk to be a nuisance. No doubt the same is true for all alternative search engines.

I remember it being the case before too. It wasn't unconditional like it is now. For example, I distinctly remember being able to scroll through someone's profile in a normal browser window without being logged in, but in an incognito window, I was immediately told to log in or create an account.

They may have had other heuristics too that led to inconsistent behavior between users. So it should not be so surprising if some people report that that happened even though it didn't happen to others.

It is, and if you choose the number uniformly at random, it's not just "effectively" zero, it is precisely zero.

GP's point, as I understand it, is that it is not actually possible to choose a number from [0, 1] uniformly at random in "real life".

I think you could argue that, e.g. in the dartboard thought experiment, the probability of choosing individual points doesn't really matter: only probabilities of measurable subsets with positive measure matter.

Some of the ideas he partially helped popularize like the concept of language shaping how we think has been pseudo-scientific nonsense that is still actively harming society today.

While the idea of language literally changing the way you think is probably not true, I think the weaker version of limiting the thoughts you can express is still interesting. What's the use of having revolutionary thoughts if it is literally impossible to articulate them in any meaningful way to anyone else?

Anyway, while the book is a cautionary tale, it's still science fiction at the end of the day. Orwell can hardly be blamed for people taking the Newspeak stuff too seriously.
