ouid··on ‘In London there is no space at all’: the rise of self-storage as rents soar
the article says london, and they parent comment says "the centre".
ouid··on Students are increasingly refusing to go to school
I can't speak to the general phenomenon, but I will say that students do not come to college with any mathematical preparation. The ones who learn mathematics learn it here.

It's actually worse than this, students have a much easier time learning to program, which they have mostly never done before, than to perform even the simplest identical reasoning in the context of mathematics.

I am forced to come to the conclusion that school is so bad that it is harmful to education. This strikes me as something to consider before worrying about whether children are attending.

This is, I am assured, the basic right wing agenda coming to fruition. Make (public) schools so bad that people start thinking of them as a waste of money, but the actual work that has gone into making them terrible has been bipartisan.

Bad teachers need to be able to be fired, and schools need to compete for enrollment, rather than some secondary measure of performance.

If I were Mark Zuckerberg's coach, I too would say anything to retain him as a student.
ouid··on What If? Driven Development
The example root cause is not even close to the "root cause", this is just the root cause that auto-dealerships would like to sell you. An additional why yieles something like:

6) Regular maintenance is often more expensive than repairing the car on failure, or buying a new car, and when maintenance predicta that a part is going to fail, the solution is still to replace it

ouid··on How we hack Hacker News and consistently hit the front page
A shill is anyone who lends credibility to a con (or more modernly, PR) by claiming to believe it themselves. This can be witting or unwitting, but if what you're doing is repeating PR, even if its because you believe it, you're a shill.

In fact, a grifter prefers their shills to be defending them in good faith. The basic currency of a con is confidence. This is easier to wield if you don't have to pretend.

Unfortunately for moderation efforts, the test for whether or not someone is unwittingly repeating PR is not easy to moderate, or, by extension, automate the moderation of. But it is a problem of equal importance to the "bad faith" shills because the effect on the conversation is somewhere between identical and worse.

If theres no way to accuse someone of uncritically repeating the lies of, say, Apple, then you will select for people in your conversations who are unwittingly repeating the lies of Apple.

ouid··on Kids who get smartphones earlier become adults with worse mental health
they say that celebrities stop maturing at the age they become famous.

Having too large a group of people know you is terrible for your ability to reinvent yourself as needed. You can't change who you are or even change your mind if your previous identity is recorded and attached to you. People need to be forgotten, and this is especially true of children.

ouid··on How we hack Hacker News and consistently hit the front page
the rule against calling other people shills is the worst part of hackernews. Skepticism is important, and important to share. I have never been anything but grateful to read a comment pointing out that another comment was obviously a shill. Perhaps I have been embarrassed for not seeing the obvious truth, but always grateful.
ouid··on Fake scientific papers are alarmingly common
Responsibility is not conserved in a robust system. This is true and it is also the journal's responsibility to not mislead.
ouid··on Helping a kid who made a math mistake
Is this a mistake in a proof or a mistake in a calculation?

Let's say that the distinction here is how we establish that an answer is correct. A proof is correct if it typechecks (no really). A computation is correct if it faithfully executes the algorithm.

This distinction is more than a little artificial, but in practice it matters a lot.

ouid··on FDIC to hit biggest US banks with $16B bill for SVB clean-up
The FDIC is the insurer of last resort. They don't get to go bankrupt.

They also wield the authority of the federal government, which is the authority of the people, represented more or less collectively, and which is operating under the principle of maximizing social utility, in contrast to the insurance company in your metaphor which is trying to maximize profits for its shareholders.

ouid··on FDIC to hit biggest US banks with $16B bill for SVB clean-up
What? Companies set prices to maximize profit. If charging more in fees was going to make them more money they would aready have done it.

This argument that you are using maybe didn't come directly from a corporate PR firm, but it sounds like one.

ouid··on Unrelated Words Puzzle
the answer to radio-ocean is obviously wave. But wave was only 14% related to radio, which is wrong enough for me to call it a bug
ouid··on Welcome to Life: the singularity, ruined by lawyers (2012) [video]
You dont have to replace yourself perfectly in order for the proposal to make sense. All that matters is that you agree the two versions are connected by conscious experience. If you take steroids that massively change your personality and mood, you still perceive it as happening to you.
ouid··on Problems harder than NP-Complete
My mistake. I, and I suspect the original commenter, was thinking about the strengthened finite Ramsey theorem. From wikipedia: https://en.wikipedia.org/wiki/Paris%E2%80%93Harrington_theor...

For any positive integers n, k, m, such that m ≥ n, one can find N with the following property: if we color each of the n-element subsets of S = {1, 2, 3,..., N} with one of k colors, then we can find a subset Y of S with at least m elements, such that all n-element subsets of Y have the same color, and the number of elements of Y is at least the smallest element of Y.

This function is outside the reach of Peano arithmetic.

ouid··on Problems harder than NP-Complete
Wait, that doesn't make sense, does it? The Ramsey function grows so fast that Peano arithmetic cannot prove that it is total.
ouid··on Fern leaves and cauliflower curds are not fractals (2012)
From the article you linked:

>Ultimately, the term fractal dimension became the phrase with which Mandelbrot himself became most comfortable with respect to encapsulating the meaning of the word fractal, a term he created. After several iterations over years, Mandelbrot settled on this use of the language: "...to use fractal without a pedantic definition, to use fractal dimension as a generic term applicable to all the variants."

ouid··on Fern leaves and cauliflower curds are not fractals (2012)
As far as i can tell, fractal doesn't have a definition. The closest it ever came was the one you roughly gave.
ouid··on Majority of gig economy workers are earning below minimum wage: research
the problem with below minimum wage labor has never been that there's no demand for it...
ouid··on Federal Zoning Bill Would Preempt Local Parking Mandates
Teachers are paid, in large part, by the federal government. What's your complaint?
ouid··on Ed Sheeran demonstrates how copyright is destroying musicians
In the desert there is only a single place to drill for water, but there is enough water if you drill there to serve everyone.

The king, in an attempt to find this well, issues a proclamation, that whoever finds this place to drill will own all of the water that comes out of it for the rest of their lives.

Most of the desert dwellers recognize that searching for this well wont keep them fed in the meantime, so an enterprising young duke offers a different deal. He says that he will pay people to search for the well, in exchange for the rights to the water if they find it.

Many desert dwellers take him up on this deal, its a good job, and it pays well enough to subsidize the searching.

When the well is finally found, the king grudgingly hands the duke the rights to the water, and with the wealth that the exorbitant prices he charges for water brings him, the duke eventually owns the whole desert and deposes the king.

That's it, thats the whole story. If you thought it was stupid, and that the king should have done things differently, we are in agreement.

ouid··on The ‘Enshittification’ of TikTok: Or how, platforms die
It's basically the very definition of bad faith to respond to a comment asking for reasons to believe a thing like this.

Valve charges 30%. I personally believe that this is an evil amount. The fact that the market bears it is, by my estimation, strong evidence of their monopoly position. The same argument holds for any "platform" charging that much more than the the cost of hosting.

Calling your opposition terminally negative is pretty shitty.

ouid··on FBI agents accuse CIA of 9/11 coverup
IANAL, but one sensible reason could be that the CIA investigates in a manner which is not always consistent with the FBI's rules for gathering evidence. Sharing the wrong information could poison prosecution.
ouid··on I'm never investing in Google's smart home ecosystem again
because its dumb to put a computer whose behavior you cannot check and which regularly receives "updates" in charge of something that couldn't even be called an inconvenience before, like walking to the thermostat or flipping a lightswitch?
ouid··on Pixel phones are sold with bootloader unlocking disabled
The internet is not a thing you connect to, what you must actually do is register your intent to disable the bootloader with an adversarially controlled server, and that server must respond with a yes.
ouid··on The grid isn’t ready for 300M EVs by 2030
load balancing doesnt work like that. the draw on a high throughput gas station is hundreds of megawatts for hours. Are you proposing 100MWh batteries installed at charging stations?

Sure people can top up their cars overnight, but what about people who street park? Charging a tesla battery to full overnight (16hr) is still 5kW.

On the other hand in the world where gas is very expensive, and you have a PHEV, you can pkug in most of the time and solve almost all of your gasoline demand, while still being able to fill your car at 20MW in critical situations

ouid··on The grid isn’t ready for 300M EVs by 2030
A gas pump fills a car at 20 MW, many gas stations operate at capacity for many hours a day with a dozen pumps active. EVs are ~4 times as efficient, but even being very generous, you've still got gas stations with the sustained power draw of an industrial arc furnace. This is not a trivial infrastructure problem to overcome. Very high power draw like that requires very high voltage transmission, which is dangerous and difficult.

Plug in hybrids are an extremely sensible intermediate step, and perhaps the only feasible endpoint. They solve almost every problem that electric vehicles solve, and also almost every problem that electric vehicles have.

ouid··on Wikipedia user edits over 90k uses of “comprised of”
the justifications in the essay might be poor, but it is sensible to restrict the language of wikipedia to be as unambiguous as possible, given its status as "authoritative on most topics".

For an example in the other direction, wikipedia should ban the word inflammable. Its original meaning, which some authors will definitely prefer (if they are pedants), is entirely the opposite meaning of the colloquial meaning. Should wikipedia pick a meaning for the word, which people are free to ignore, or just outright ban it? (except in etymology wikipedia, where it is an example of a word, rather than part of the explanatory grammar)

ouid··on How companies use dark patterns to keep you subscribed
Well, exploiting brand loyalty is also a dark pattern. The better your brand, the more you can sell it for.
ouid··on A Programmer's Introduction to Mathematics
The current state of the metatheory of Banach tarski is that it follows from the ZF + Ultrafilter, but not ZF + dependent choice, and has very little to do with the excluded middle.
ouid··on Up next: a lawsuit threatening your YouTube watch queue
it doesn't have to be "displayed" at all. It doesnt even have to be searchable. Once they start selecting things to show you, they stop being a host and start being a publisher.
