That's effectively a pull-based system, which works fine but is inefficient. With a binary dependency tree of depth N, you have to touch 2^N nodes in such a pull-based system every time you evaluate it, no matter how many nodes you may have updated.

If you only updated 1 node, a push-based system will only update nodes that have changed, which will be considerably less (likely linear in depth). For instance, consider:

var evenSeconds = clock.Seconds.Where(x => x % 2 == 0);
var countEvents = evenSeconds.Count();
var minutes = clock.Seconds.Count(x => x / 60);
var hours = minutes.Count(x => x / 60);

Even though evenSeconds and countEvents is only updated every other second, and minutes once every 60 seconds, your pull-based approach will have to check all nodes up to the root every time clock.Seconds changes.

In a push-based system, clock.Seconds would trigger seconds+1. If that's not even, propagation stops there, if it is even then this updates evenSeconds, which would then trigger an update for countEvents. Ditto logic for minutes and hours.

You can see the push-based system permits minimal state changes via early termination if downstream dependents won't see any changes.

You said violence is increasing, which is fear-mongering and needs citation.

> Never before in human history have humans lived in densities that they live in modern cities

Citation badly needed. We're in a crisis of low density in almost every urban area on the planet thanks to the auto industry and zoning laws, which I'll explain below.

> I’d want to see evidence that “It’s illegal to build walkable areas in most of the US”.

Ah, so the problem here is that you're interpreting the existence of sidewalks as walkability. That's not what it means: https://en.wikipedia.org/wiki/Walkability.

Walkability is a complex concept dictated largely by zoning, the practice legally defining the type and qualities of structures that can be built. And zoning, almost everywhere in the US, prohibits walkable urban design: https://duckduckgo.com/?q=walkable+neighborhoods+illegal+due...

The desalination plan provide water when the groundwater reservoirs are too low to fulfill freshwater demand.

I don't own a car but I use to think it is worth paying for roads since I benefit from postal services, busses and stuff being delivered to stores.

But I have no idea how road consumption is distributed. (they don't last forever)

I could in theory just as easily pay for that though the normal channels. It can just be included in the price of goods.

Parking spaces consume a very expensive amount of space in cities. If someone hardly ever drives their car(s) sould they have to pay the same?

I'm not a fan of capitalism but if you want such a system to work it should be allowed to scale prices with cost? It would have to be regulated to avoid driving up the prices to what people can afford.

Bicycles and pedestrians use roads too. Billing everyone doesn't seem very challenging. Many highly used areas could really use maintenance and cleaning.

I honestly have no idea which products and services would get more expensive but the benefits and cost are distributed weirdly.
I mean, I get it. But shaving 4.5ms does seem to fall into the realm of not most peoples problems?

Note that I want to stress that that is no reason for some folks to stop focusing on it. And kudos on the improvement. Criticism, if any, here is that statistics once again rears its head to make something feel bigger by using a percent.
Production does scale with human labour input. At small increments it scales linearly, but you get scale efficiencies as you ramp up. Then you satisfy demand at a certain price point and reach equilibrium.

But if you can dramatically increase productivity per worker and for a given capital investment, your costs stay the same but your production is now higher and you can cut prices. That stimulates demand which mops up the available supply. Now very broadly several things can happen, it's more than the below but this isn't an essay.

One effect is the price of production drops, you raise margins a bit and cut prices which increases demand. The company makes more money and society gets more stuff at a cheaper price. If your product is itself productive, like it's a tool, then your customers can produce more with it more cheaply. Your company is more profitable, your society gets even more stuff. Your customers are better off, so they can hire more people, buy more products, pay people more. It's great all round.

Another possibility is demand goes up so much that in addition to the above your company can expand, increasing production further with more scaling effects, hiring more people, maybe also developing new products because it can invest more.

So productivity increases can wash through the economy raising all boats. That's partly what GDP growth is, and it's one reason why for example the lowest 10% by income in the UK now earns twice as much in purchasing power parity than they did in the early 80s. That sounds great, and it is, but middle incomes have stagnated the most and inequality has risen. Fairness matters, but raising all boats is worth doing. Let's not let the real social issues we do have blind us to economic reality.

Makes me realize how spoiled I am by standard libraries nowadays.

Outside of toy projects, interviews, and teaching them, I've never actually written a sort function.

A bit odd that Pinecone is publishing this…

if their theory holds true that means private sellers were massively under negotiating, or that there is a large arbitrage value between when a seller wants to sell and the days on market.

ie assume seller is willing to pay $50 a day to have car sold today (and not have to field calls etc). That means selling a car a month faster is worth $1500. Carvana can borrow the $25K car value at ~5% to pay $100 interest to hold the asset for a month playing the time arbitrage.

I'm finding one thing that seems to be happening generationally (or just in my experience) is that folks are far more willing to pay for convenience/now. That means they'd rather have the $25k and car sold today than have the $1500 in their pocket a month later (and field calls etc).

I’m glad people are enjoying Ozempic. My experience from seeing a family member on it, is I would not touch it if I were a 500-pound alcoholic smoking two packs of cigarettes a day. That’s an exaggeration since it probably outweighs the health issues there, but only slightly.

The person I know taking Ozempic has only lost weight (35 lbs) due to the fact that eating now makes her sick. She has been sapped of all energy and has developed issues with her bladder, circulatory system, joints, thyroid, and digestive system since starting Ozempic. I’m not saying it’s due to Ozempic, but I am saying all these issues have cropped up in the few months since she started taking it, and she never had any chronic health issues prior. At least she lost some weight, I guess.

I don't think you're romanticising at all. I visited (of all places) Mariupol, in 2013. As a city built around the Azovstal steel works, it was still horrendously, actively polluted when I visited. But it also beautiful. Dozens of parks with ice rinks, sports grounds, lakes. Each soviet era block was surrounded by greenery, and despite the wide thoroughfares the city was indeed quiet and friendly. Not to say it was idyllic - the pollution was horrific, the poverty was grinding. With little in the way of pensions, the elderly people were forced to sell jams and preserves from their apartments to survive. Each building had an aging guardian in the doorway - and I was told my by Ukranian partner that part of their function was to prevent the apartments being stolen and sold out from under their residents. But in terms of urban greenery and place spaces, few places I've been, including relatively green bohemian cities like Berlin, come close.
Genuine question here. What would be the expected change over the same period? The abstract says 53% of lakes saw declines...does that mean 47% saw no change or gains? If so, that seems pretty close to net stable to me globally. Or frankly what we would expect to see (some gains, some losses)

Also, this is stated later in the doc:

"Between 1984 and 2015, a loss of 90,000 km2 of permanent water area was observed by satellites—an area equivalent to the surface of Lake Superior, whereas 184,000 km2 of new water bodies, primarily reservoirs, were formed elsewhere (14)"

My first impression was that this means there has been a growth in total permanent water area from 1984-2015. Am I just reading this wrong?
