This might be true in a few years, and I am excited too. As of now, there is no help from ChatGPT in developing a complex app. ChatGPT can create mashups, straightforward web code but anything that involves thinking is still out of reach. It can't even be used to generate a consistent ui framework let alone algorithmic code. If you tried using it and skipped all the twitter clickbait you know what I am talking about.

Being able to take an arbitrary word problem and turn it into an algebraic equation (or series of equations) and be able to solve it. That a huge percentage of kids graduate high school being unable to do that means several people (mostly parents but likely the school system too) failed them.

Its called 84 watt-hours and this is energy consumed in 24 hrs. 3.5 watts is energy consumption rate and is called as power(joules/sec). 84 Wh is not actually lot.

If I read the page correctly - and I am NOT knowledgeable about the topic - the CPDLC is not used for approach control, which is the issue in NYC and DC. The example uses given are oceanic routes and above FL195 or FL285. It mentions "continuous descent approaches" as a future possibility.

Isn't approach one of those times where 1) you don't want the pilot distracted by more visual information (instead of audio), and 2) pilots listen to exchanges with other pilots to keep situational awareness?
This is the essence of NIMBY reasoning.
Because tone mapping from an high dynamic range to a standard dynamic range is not standardised, there are some recommendations, but each app uses a slightly different algorithm.
Then an app might implement tone mapping for HLG, some might display it as it is on a SDR screen (HLG is supposed to be watchable even on those old SDR screens.)
Or implement it mostly properly, but ignore the current screen color profile.
Even for SDR, some apps don't implement Bt.1886 yet, so you might see different results.
> You are simply required to memorize these rules because if you fail you are a failure.

Interesting take, completely opposite of my educational experience.

I have a terrible memory for remembering random things so I always did badly in subjects that are all about memorization (like history). Math was my refuge where I excelled, as it didn't require to memorize anything. Everything could be derived by logic; I could solve all problems on the spot during tests instead of having to hope I memorized the right answers earlier.

All other classes were of the form: (1) teacher presents a bunch of facts; (2) I'm supposed to memorize them all; (3) then I need to regurgitate a random sampling of them back during the test. I hated that so much. Math was the exception to that pattern, so I loved it.

> I think it is a joke that

Standards change greatly with time and it is a joke to believe that applying the same standards to everyone will get a good outcome.

Anecdata: I would have loved to get the possibility to study higher math at high school level, at school. I had to dig it out on my own since the local school topped out after basic calculus, linalg, statistics. I was not alone.

Today I would estimate that top 5% could easily and happily handle multivariate, ode/pde, etc in high school given proper support and encouragement.

Top few percent learn several times faster than average. What is the point, other than ancient ideology, to slow them down and hinder their learning progress?
That's the same kind of thinking that would criticize pharmaceutical companies for giving placebos. They do it because they don't know with confidence, and they want to. They are collecting evidence.
Math is a hard, abstract, mental discipline, so it’s very plausible that mere exposure to some concepts increases the subsequent understanding.

For example, I was one of the best students in class, yet it took me about a year to really get stochastic processes.

Taking advanced classes could be valuable even if you need to retake them.
For a comparison, 50W doesn't seem like much, right? Maybe if you're older you had 50W incandescent light bulbs in your house. Normal thing.

Let's say a WISP wanted to run a very basic off grid relay site with some radios that are 8-12W DC load each and a router that's 15W. Total around 50W 24x7x365. ((50 x 24 x 31)) / 1000

That's 37.2 kWh per month.

You need a surprisingly large amount of solar panels to generate a reliable 45-50 kwH per month to refill a battery bank every day when the sun comes up, in November, December, January, February at latitude 45N or above. Like, really, a lot more than you might think. Four or more 370W 72-cell.

If you end up with useEffect hell, you are coding wrong. As OP said: it deduplicates and caches requests, there is no need to use useEffect.

Here is some example code, and imo it‘s really greener than anything else.

async function getData() {
const res = await fetch('https://api.example.com/...');

if (!res.ok) {
throw new Error('Failed to fetch data');
}

return res.json();
}

export default async function Page() {
const data = await getData();

return <main></main>;

> If you ever intend to build some kind of solar setup yourself, consider a 24 Volt or ideally an 48 Volt system to reduce currents and thus save on cabling cost.

I sort of regret going with a 48V system because it prevents me from plugging in a lot of devices directly to the battery. I have a few USB-C PD fast charging modules I would want to use directly. Also a battery-to-battery charger such as an iCharger or ISDT product won't do 48V as input or output. Not a big deal if you just want to connect an inverter all the time.

A more relevant issue may be that your solar panel's voltage will have to be > 48V. Actual voltage will depend on your MPPT charger. Victron seems to require battery voltage + 5V. Mine requires a minimal of 60V from the panels, so I have 3 24V panels wired in series, and cannot downsize.

I think 24V would've been a good sweet spot. The USB-C PD modules only step-down, so they cannot output 19V with 12V power.

That's absurd reasoning. Once you have a battery system, you don't worry about Carnot's theorem and therefore you aren't limited by the efficiency limits of heat engines. It's pretty much an imaginary limit after that, and is similar to all of those people who didn't think Moore's Law could continue past some arbitrary point.

Hydrogen and lithium are both on the same column and have one electron in their outer shell. They should have very similar chemical properties. You're just demonstrating the problem I was talking about: That the facts should be driving a strong motivation to solve these problems. Instead, it is just a series of excuses to not try. As if climate change just wasn't something to worry about.
That's what I thought throughout the article. I wonder if it is a typo or the author is confused about East and West?
The Praetorian Guard appointed Claudius as emperor, and had assassinated several others, all of which could be considered, arguably, a major step in the downfall of the Roman Empire.

Remember, this was a response to illustrate: ”When your military suppliers and contractors become large enough to buy the government, they grow like a malignancy, bleed the productivity and resources of the empire into building things that explode, and kill the host."
I love constraint programming. It allows you to code very close to the original spec. There are differences between systems though. Z3 might have a good raw performance, but using it feels like programming in "two worlds". In contrast, Picat or Prolog integrate seamlessly with constraints. I did a talk about constraint programming with Scryer Prolog here (Spanish audio): https://www.youtube.com/watch?v=c_yP_kr7DxI

Fantastic! definitely bookmarking. I spent a big part of the last few days attempting this, my model didn't come out nearly so well. I decided that it was because I don't have enough training images, and so have been taking 3x as many pictures of my dog to compensate.
People react to things differently. They also aren't complaining "about everything." They're highlighting a specific problem with a specific product and using a single exterior example to make their point.

While they had a strong reaction to this that was over the top at points, I still feel it was a worthwhile thread documenting a new problem.
My kid is currently in elementary school in a desirable district in Menlo Park. On the first day of school, the teacher sent home a list of expectations for what the students should be able to accomplish by year-end for math. There were expectations for multiplication and division problems (x number correct in y minutes, up to 12s). I had my daughter attempt this a couple times that week, and messaged the teacher on Thursday to ask what the process was for demonstrating her proficiency.

We were told that she could not test out of the standard path. She literally had to do 1s and 2s multiplication tables worksheets alongside students who are learning this material. She is allowed, during free time, to do Khan Academy, where she is several grade levels ahead. However, she is so loaded down with busywork that even though it's now April, she still hasn't yet finished all of the multiplication and division worksheets. As a result, there has been very little free time during which she could actually learn anything.

The most frustrating thing is that we're not even looking for the teacher to provide advanced instruction — just to let her go off and do KA on her own.
re: mirrors: It's because they don't mirror left-to-right. They mirror front-to-back.

Some experimenting with a dry erase marker and a piece of glass will demonstrate this. Write some words on the glass and hold it somewhere in front of the mirror. You'll be able to read the text on the glass and in the mirror simultaneously. The mirror did not flip the text around at all. If instead you write the words on paper it only seems to do this, but notice that between looking at the paper yourself and looking at in the mirror you're doing the flipping of the paper.
I would classify a trick as something that happens to work but isn't rigorous. Like treating dy/dx as a fraction sometimes works, but only under certain conditions.

Kids don't need "support at home from parents". Very few parents are competent to teach kids math properly (even those who think they are). Kids do better learning from someone else, better still if the someone else is a professional.

Tutoring rarely helps anyone learn as it almost always consists in heavily guided spoon-feeding. Also there are very few good tutors as those who are adequately trained in math to tutor it have much better employment alternatives (including teaching).

In 25 years teaching math in universities I've never seen a student who used a tutor and learned math at the same time. I don't teach my kids math and I don't help them with their homework. What kids need is teachers who know math.

Google Keyboard is multilanguage too, if you mean having multiple languages active at the same time and the swiping/hints responding to both. I'm currently typing this comment using it.
If a keyboard app feels like an extension of your body, it means you write a lot. It doesn't mean that you are "terminally online", and even if you were online all the time, that's a personal choice and not being online all the time doesn't even solve the problem shared here.

I'd even say, perhaps it's best not to tell people that their problems aren't problems to begin with. I'm not saying one should care, it'd be enough just not to explicitly dismiss on their face.
I might be misunderstanding, but could OP mean ‘age’ and you mean ‘portion of lifespan’?
Objectively your application has already been designed by the framework you choose. It tells you how to do and where to put most things and it also does all of the heavy lifting, a.k.a. actually doing something useful. The design the application developer needs to be concerned with is how to split functionality into reusable components where it's needed. I mostly see big fails here: a lot of kind of best practice theater, but what you end up with are very complex components doused with concrete.

I also see some straw man arguments, e.g.

> Developers dislike design because it's time-consuming.

I've never met a developer who doesn't like to design. I'd say the vast majority of developers even if tasked with something as simple as creating a button first try to craft a universal solution that can somehow be reused. Instead the correct design methodology most of the time is called KISS. You can always make it more complex later, but making it simpler is usually a lot more difficult.

I just checked - the panel on my toy system faces directly east but only gets about 2ish hours of non-optimal light a day (between 10ish and 12ish - after that there are chimney shadows) due to houses being in the way. This is peak in summer - for the rest of the year i get less because the sun is lower longer.
This is why I enjoyed doing math contests. You always got these problems that illuminated how things actually work, and the answer is always some set of basics applied to elegantly solve it.

I'm actually looking for a set of such problems as I think it's a lot better than grinding out hundreds of quadratics or polynomial derivatives and such. I found the AOSP stuff already, wonder if there's other good sources.
Not judging you, but havent you heard of machu pichu. That is in Peru.
"Fuck every math department. Every fucking math teacher, professor, and administrator who buys into this math reform shit can fuck right off."

Essentially no mathematician buys into this stuff. In general professional mathematicians and mathematics educators are little involved in the processes that design curricula in public schools. They are simply not included. No one feels more threatened by expertise than education school professors.
> Growing up in Seattle in the 90s, the school district was obviously racist and classist. Advanced programs were in the richer (whiter) neighborhoods and poor kids got to go to schools with police wagons out front.

I grew up in Sacramento in the 80's/90's, and the best schools were not in the rich/white areas. The top-performing schools were in so-so neighborhoods, and the schools were very diverse. Best of all, you could test in and enroll from anywhere. We literally had a kid in HS who drove down halfway from Tahoe each morning. It wasn't perfect, but it was much, much better than what we have now, as this article shows.

Tip to OP (I think they already have this idea, based on the post): when that lead-acid battery dies, replace it with a LiFePo4, which is substantially more efficient, lasts 3x as long, has a higher energy density, provides a usable voltage far further into its discharging %, etc. etc... A couple pages that describe the differences linked below...

tl;dr if you are starting a solar battery project, LiFePo4 is the clear choice by far, unless you're going for the absolute cheapest possible build due to immediate budget constraints.

Denmark has had a private school system for decades, and 15% of students go into the private schools (as a parent you pay a portion of the costs so it is not necessarily extremely expensive). "Private" mostly means that you still have to teach specific basics, but you can do it in your way like Montessori.

One advantage of the private schools is they can kick out students they cannot manage easily, while the public schools have to keep everyone. Some recent strutural changes in the public shools are said to have declined their quality, enough so that many government ministers, even of the left wing, are sending their children to the private schools.

I guess it's one of those Nordic myths -- like high minimum wage (there is none in Denmark).
