How about we start regulating ship engines? There are currently no regulations involving large ships' emissions. But they are extremely dirty, emitting tons of unfiltered sulfur in per voyage. They use different fuel, with much 3.5% sulfur content while road cars' fuel is 0.001%. This all goes in the air.
I find it unacceptable that we consumers bend over backwards changing our habits, but the largest emissors don't change one bit and emit literally tons of sulfur in the air per voyage.
The e-up is only cheap as long as you don't compare to other cars equal in size. VW is far behind in EVs for now sadly.
Good suggestion, but the data is semi-private and I have no ownership of it. May be worth a shot though, thanks!
YAML is fine as a user. It can be just JSON without some of its visual clutter if you like brackets, or much more concise if you prefer.

All the complexity related to anchors and such is unfortunate, but that’s a problem for parser writers.
An aging economy would experience inflation since there aren't enough young people to take care of the old people. In practice old people keep working because they can't retire.
I started investing and saving for retirement in mid 2015, and the most I’ve made was just over 60k/yr.

Got about 50% total return since then (121k purchase & 61k return 183ish total). Mostly in VTSAX but the thing is, in late March 2020 I was negative returns, the market really does fluctuate and it is important to not act irrationally. Now it’s 50ish percent return since then.

Now the long game here is that based on my age I only had to put money into retirement for like 5-6years (employer match 401k + Roth contributions) now this will just be left until retirement in 30-40 years assuming the current approximate interest rate of 7-8%year inflation adjusted.

So yeah, just buy as much VTSAX and let it sit for decades. If that doesn’t work the economy of the United States is broken and you have bigger problems to worry about.
It's a moot point since the author already said he's not using fork(), but C and C++ apps don't transitively pull in dependencies, especially in the open source world.

That kind of thinking comes from node.js and Rust as far as I can tell.

There is never ever a situation where a program like GCC or Clang will acquire a third party dependency without a commit that explicitly changes the build system.

The Python example isn't really relevant because Python modules are shared libraries, but a linker doesn't have or need shared library plugins (i.e. dynamically linking against arbitrary machine code at runtime).
I'll chime in on this, it won't be possible to keep the same level of decorum as before to drive these points but here it goes: Abrahamic religions have the same source material. They all branch off based on the consensus of who the self-proclaimed prophet is, or the consensus on a lack of prophet.

Christians branch off by following Jesus Christ. Nobody else follows that, to many people the whole story jumped the shark when one guy (Saul/Paul) decides to reform his life and go on a Eurotrip to talk about Christ and comes back with a story that has incorporated regional religions along the way. Now there are ghosts, and devotion due to fear has been replaced with devotion due to love. A lot of people just disregard that part because the "New Testament" is inseparable from that guy being the major contributor. The world has basically been splintered in three for the next two millenium because its a different story.

700 years into that, after two major councils that try to reconcile this, people are still like "yeah we're all in line with season 1 but season 2 eehhhhh we can agree the guy was inspirational but" and mostly ignoring it. New sects of Abrahamic religions continue to pop up and continue from older events and books because of the wide consensus that one branch was practically procedurally generated.

So the book of John is in the "New Testament", and if we are acknowledging the similarities of Abrahamic religions it means ignoring the New Testament just for the sake of comparison. When looking at the base material, which Christians also rely upon for inspiration or as rules on how to live life, they are very compatible. The primary distinction of all of the Abrahamic religions is the divinity of the prophets or lack thereof, and thats where the incompatibilities are. It isn't useful to make an example about who says Jesus is divine, when thats the primary distinction by definition. After you get past the prophets, there are more similarities than differences.

Because later if you want to reuse parts of the code in a continuous environment (e.g. a daemon), then you will be surprised that you have memory leaks all over the place (or worse, someone else will discover it by accident).

I don't have a problem with the end-of-process-releases-all-memory optimization. But I had the impression that the author uses let's-worry-about-leaks-later-because-OS-takes-care-of-it-for-free-(in-my-use-case).

Best approach to take would be to create a memory pool with fast allocation (e.g. TLAB allocation in Java, or how computer games do it), in order to have control over how the memory is freed or when.
The WHO really dropped the ball in early 2020, since they were also recommending against personal mask use.

That said, I think it's fair to say that some kind of response might've been faster in one place vs another... But any response at the beginning was taken out of caution (again: no healthcare workers infected, no deaths, no proof of human to human transmission)

Taiwan was obviously wise in applying caution, but did they actually publish any kind of statement regarding their beliefs for h2h transmission? (I'd be surprised if they did, since without cases there hadn't been any samples, and research on the genome of the virus couldn't start before Chinese researchers uploaded it online one January 10th)

"Based on the available information there is no clear evidence of human-to-human transmission" does not mean that there was no h2h transmission: just that there was no evidence, yet.

Everyone reading this stuff was obviously concerned, but again: if you remember, the 2nd death was only confirmed on January 15th...
I’m not sure the analogy holds. Radio in its current form is a marketing device for new music and stations get paid by record labels in order to feature new releases.

I'm not an expert, but yesterday I've heard from a pilot that most US gyros don't have a tail stabilizer (is that how it's called?), unlike the Magni models (Magni is a small Italian manufacturer of gyros), which don't have the problem you are describing.

If there's an expert, I'd love to hear if what I just wrote is correct.

When people get tired enough of crappy behavior from other people, regardless of the excuse, people tend to do something about it.

This is why we have sayings like "what goes around comes around."

Business exists to serve humanity, not the other way around. Humans created it to serve human needs. Humans can exist without business. Business doesn't exist without humans.

Historically, the honey bee was revered as a symbol of a civilizing force and the force it symbolized was trade. Trade -- aka business -- is how you make the world better pragmatically. It operates on the idea that both sides gain something of value.

I don't know how or why, but we seem to have collectively forgotten that.
Also, avoid using dishwasher and dryer. But some types of plastic cookware is just a pain to clean up. The only solution is avoid buying any plastic cookware or food container completely.

Unheated food-grade plastic is generally okay, but when exposed to heat or UV light, you have a big problem.

Stagflation is what happens when the central bank engages in expansive monetary policy but there are barriers to starting companies or working at jobs. This describes American healthcare, education and housing pretty well but it's a long term trend.

Think about it. The fed gives a bank money, the bank gives money to you so you can build a house and then the city denies you the construction permit. You decide to just buy an existing house instead.

The only thing stopping this democratization would be crash-worthiness. While this is more true for Western markets currently, regulations will come to India as well.

However many Indians ride in the 3-wheeled death-traps called auto-rickshaws so I don't know... I've personally been in one which almost rolled over when the driver made a sharp turn at (relatively) high speed.

For comments in plain JSON a common approach is to use keys like "comments" or "description" in object literals.

As for trailing comma the only real issue in practice is noisy unified diff output. But for JSON word diff or similar works better in any case when the trailing comma is not an issue.
From the very page you link to:

Nonetheless, according to Stephen J. Lukasik, who as Deputy Director and Director of DARPA (1967–1974) was "the person who signed most of the checks for Arpanet's development:

"The goal was to exploit new computer technologies to meet the needs of military command and control against nuclear threats, achieve survivable control of US nuclear forces, and improve military tactical and management decision making."
We used to think so, right? Then the pandemic arrived, and restaurants started offering takeaway meals only, and... lo and behold, the prices are the same.

Besides, I have many other issues with cinema popcorn specifically. I don't care it's terribly overpriced, but basically most of these venues don't offer any healthy snacks AND you are forbidden to bring your own, so you either eat shit or just sit there hearing all others eat. Fine for an adult, but when you have kids, this becomes really frustrating.
> the range-optimal speed is where the parasitic drag is equal to the lift-induced drag

Not quite true -- range-optimal speed is where the sum of those terms is minimal. With some assumptions, this is where the derivative is 0, dDrag/dv = 0, and since derivative is linear, this means: the range-optimal speed is where the (infinitesimal) increase of parasitic drag (with speed) is equal to the decrease of lift-induced drag (in other words, opposite derivatives).
How could that have been solved?
Shipping only count for something like 2% of human caused release of CO2 and the pollution isn't local (cars inside a city is worse for humans). I agree something should be done ASAP but it isn't a low hanging fruit (hard to regulate worldwide shipping) so I doubt it will happen anytime soon.
This is one of the reasons companies should be forced to decentralize (as it was the case in Spain, though it was not forced).

I am glad to see that some companies moved south of Paris (Thalès, Bouygues, Dassault Systèmes,...) and people working there and living around our in Versailles can bike to the office.

If we managed to spread companies in the country, we would have less concentration of elitarism and pepole would live a more quiet life.

I'm not. I just didn't want to quote that entire section; it's a TL;DR, after all. The title of the article is a little misleading.
The hospitalization rate and resulting panic could do it, though. Hospitalizations were about 20% of cases; worse, the rate dropped off less for young people than the death rate did, so while your chance of dying from COVID as a 30-40 year old was only about 1 in 2000, your chance of being hospitalized was about 1 in 30. Having 1 out every 30 people in the labor force hospitalized will shut down a lot of workplaces, particularly if their coworkers want to avoid the inconvenience (and $100K+ hospital bill).

I have an acquaintance that runs a box factory. Their COVID outbreak resulted in only one death, but it knocked one whole building out for about 2-3 weeks. Reportedly their competitors each had 3-4 such outbreaks.
I'm starting to believe that prices in supermarkets without taxes are a very, very good thing.

It's baffling how many people here think they don't pay taxes AT ALL. While in reality they pay around 20% in prices of goods and around 1/3 of their pay at work goes to mediocre public health service and taxes.
> We got a water filter for this one.

Is that enough?

I keep reading about how microplastics can be too small for a carbon filter and that you would need a reverse osmosis device, to completely remove plastics.

I can't say am really sold on using a device with a plastic membrane to completely remove plastics.

All the online materials on the topic are for the majority just product placements, it feels very disorienting to be able to make a data driven decision. Do you have any insight.

I wonder if the divergence between Asian and Western countries in sperm count is due to cultural reasons. Maybe the fall of traditional culture in the West, and all the allowances it made for male behavior, has had psychological effects that have something to do with it.

Plastics are massively used in Asia, which is why I speculate the cause could be psychological as opposed to chemical.
I recently started in the book “The value of everything” , and it’s the first book to give me a solid understanding from the early theories and it’s working its way to today. Especially the decomposition of where the theories differ is enlightening. I just arrived at marginal utility theory. It explains it far better than all the classes I had in economics.
> Transportation is expensive, both from a relative cost perspective, and also from a resource(-wastefulness) perspective.

It really isn't. That locomotive running flat out may use a lot of energy. But it's also moving an enormous amount of freight, making the energy used per unit mass fairly small. For instance, CSX estimates it can move about 1 ton of freight 492 miles per gallon of diesel: https://www.csx.com/index.cfm/about-us/the-csx-advantage/fue...

Your trip to the store and back will probably use more energy.
>In a lot of ways I think the cost of housing is dependent on the housing density vs job density of the area. If job density is much higher than the housing density, then the price of housing goes up by a lot.

The cost of housing is dependent on job density * quality only to the point what people are able to pay, and then rest is what they are willing to pay. A lot of people buy/rent slightly above their means if they are willing to pay it. Housing price is like an auction house so willing to pay is a bigger factor than able to.

Artificially reducing number of available houses comes in a lot of reasons/pretense but in the end its just a result of people seeing/forced to see their house as an asset; You acquired your house at price X at auction. A local urban developer want to build 100 more units close to you, from prediction of demand and would be profitable at price X (or even <X), so you passively/actively work against that proposal, tell the developer that he can build up to 90 more units, so price of your estate increase X+N. Now the next 90 buyers that bought the house have a reason to keep the price of estate above X+N, tell the developer that he can only make 80 units. Rinse and repeat.
I'm talking about stock investors. People tend to buy on anticipation, so the folks who get in early drive up the price for the folks who are waiting for a sure thing.
It's also evidence that they're doing science properly. You don't declare causation until you have reason to believe the arrow of causality goes a certain way. You can distinguish between “doing science properly” and “progressive bias” by seeing how the authors treat papers where the conclusion could be spun “progressively” via unscientific conclusion-jumping… of which this is one, I think.

A problem with such tiny cars is that they cannot absorb enough kinetic energy in a crash. Although they cannot go very fast compared to traditional cars, a frontal collision between two tiny cars going at full speed will likely have severe outcomes for the drivers and passengers. Of course, it might get worse when they get hit by a faster driving traditional car.

You are aware that tofu/tempeh/s. milk are made out of soy, right? I'm seriously concerned that one mass production (meat) will turn to another. The mass producers need to sell.

I hope my comment does not start a carnivore vs vegan war (as just like you, I'm neither).
That's kinda what I'm saying. It's not all "pretend" either. It's a goal, just not one we're willing to devote any resources towards. It's worth pointing out the difference. We want ex-cons to get jobs, just not working with us. It's the "not my problem" culture that is the USA.

I don't think that example you gave is a flaw in the logic. We don't know when people are rehabilitated, and there's reasons for having minimum sentences, whether you agree with them or not.

The greater issue in my opinion is that we do a bunch of stuff to create this illusion of safety for the public (and businesses), and we're not willing to budge to give people a chance. We very reluctantly pass laws that clear some peoples records if they're young enough and haven't done anything so terrible... and that's if you're lucky.

Disenfranchisement should be an exception for people that are likely highly-dysfunctional, not a general purpose solution. A new despised underclass to place a substantial percentage of the population. Seems dystopian to me.
Your comment seems to rest upon a claim that we do not have flu vaccines. In fact, we do, and about half of all US adults are vaccinated against the flu every year — and more than half of US children are vaccinated, since the flu is more dangerous to children than adults.

Do you have a specific strain of flu in mind when you claim that we have reached herd immunity "to various strains" without vaccination?

I don't think we can come anywhere close to ruling this out but of course we also don't know how many people felt this way before and hid it so the data is far to muddy to make a clear conclusion.
Echoing this sentiment. I spent years doing mental gymnastics to justify my meat and dairy consumption. Going vegan was a great release of that mental tension.
you mean versus having a product that loses money ?

Uber was losing between $1B and $5B a quarter when they IPO'd. In the last quarter of 2020, Uber lost close to $1B, and they're still valued at $108B, with no real long term plan for survivability. The way I see it, risks include legislative changes WRT driver status, bad press, self driving cars, a post pandemic world where more people own a car, and less people are in cities. And we're talking about a company that is primarily marketing and software, where the wind can change very quickly, and assets are mostly intangible and untransferable.

car manufacturing is much harder to get into, so having a factory and an almost-complete design is already a huge milestone. Obviously, they'll need to sell _some_ cars, but they could even make money if they were to sell cars at a loss, through carbon credits.
