The article measures mobility based on one's percentile movement across the income distribution. There are more rungs to climb in the US because there's a wider income range, whereas in Europe income differences are compressed. The same income increase in absolute terms gets you more social mobility in Europe than in the US.

I'm initially skeptical of studies that imply large-scale misunderstanding among the public about their own lives; here that Americans are too optimistic and Europeans are too pessimistic. I'm sure there's some truth to it, but it's not the whole story. The conclusion of the article is in part a reflection of the methodology.
It's also not too hard to make your own, be it for MacOS or really any modern operating system. Just write down all of the changes you make on a fresh install, script out each line and you're pretty much golden. It's definitely a lifesaver when stepping onto a new machine.
hmmm, I was thinking of doing their Tesla rental....but given the risk of being falsely arrested that may not be a good idea.
I feel the flaw is in building ontologies. Satic ones, at that.

There is great value in reducing type errors at runtime. Is hilariously ironic that one of the main tools we reach for seems intent on just moving them to design time.

Notably, not compile time. Design. Most failures from mistakes in ontology stall the problem out before release.

I think perhaps the US makes it hard for a single person to move from bottom to top quintile. But I bet that the US is the country that makes it the easiest for you to be in the bottom quintile and have grandchildren in the top quintile.

Basically, I think the US is likely the best for generational family mobility. I have seen this story many times with immigrants. The immigrants come over and work often very menial jobs. Their kids study hard and go to colleges and end up as white collar jobs. Their kids in turn (the grandkids) often go to elite colleges and end up with elite careers (lawyers, doctors, etc).
I ate dirt as a child. Dirt is natural, healthy, and as long as the shit in it is broken down, pretty much harmless. I have a great immune system to this day. My little brother, who spent his early childhood in the city, is nowhere near as robust, and gets sick frequently.

It could definitely be better, but I think there are more opportunities than most people realize. Joining the military is a big one; you get paid to learn a marketable skill, usually have your college tuition paid for, and you get to move out of your hometown. I knew a few people who joined because it was a quick way to get out of their shitty hometown where the options were sell drugs, or be poor.

Knowledge of what's available would probably go a long way towards helping people move up. My wife grew up in a small rural area with no job options besides Wal-Mart and fast food joints, and she hated it so much that she ended up getting enough scholarships to make money earning her undergrad. She's the first person in her family to go to college, and most of the rest think college is super expensive, and don't know about scholarships to help poor people go.
> I think it would be easier to become "filthy rich" for a poor person when they start in a nation with free healthcare and education.

Poor people in USA have both free healthcare and education. If they're willing to fill-out some forms.

Yes, contrary to the popular belief, poor people in USA do, in fact, get free health care and education.
That's exactly what this story is about -- people who have sued Hertz for wrongdoing.

Hertz is going through bankruptcy proceedings. During this process, a court will prioritize which debts Hertz is going to be paying off, and in what priority. Some of these debts are people who have sued Hertz for these issues. The court will be determining who gets paid and whose debts are written off under bankruptcy law.
Just looking at Figure 1 on page 8 of the paper you mentioned, it can go either way because we haven't seen a reversal in any of the trends. That is hardly a prediction. For example, if one looks at the "Services per capita", is there any sign that it will meet an inflection point in the next few years?

I know it is always appealing to tell a story with a grand unifying narrative. But sound research must prop it up with empirical evidence. Could there be limits to growth? Probably. But a highly simplistic model not informed by appropriate data or economic understanding is not the way to tell such limits.
> I remember seeing a paper referenced here once explaining why that energy loss is actually necessary, but I don't seem to have it saved anymore.

Taking a stab at explaining the energy loss…

When computing you are reducing local entropy (e.g. achieving a certain pattern of electric charges in chips and a certain pattern of pixels on the screen) while still increasing global entropy (the second law of thermodynamic). Heat dissipation from the local system to its surroundings accounts for the difference.

This is analogous to Schrodinger’s description of life where life forms increase the entropy of their surroundings to maintain their own low entropy.

Of course the real redistribution is the expropriation of the fruits of surplus labor time by those who work to heirs who do not. Redistribution in this context is giving value back to the workers who created that value.

> In 2017, a study found that as much as 62% of the cadmium from cadmium telluride models were leached out at room temperature depending mostly on acidity of the solutions.[3]

From the related article:

"The pieces are cut out from modules of the four major commercial photovoltaic technologies: crystalline and amorphous silicon, cadmium telluride as well as from copper indium gallium diselenide."

So they cut pieces from a sealed module? Seems unsurprising that leaching would occur when you cut pieces of a PV panel and expose it to acidic solution for an extended period. Functional installed solar panels are sealed behind a protective glass panel.
Beautifully simple to read and understand. The speculative nature of employee stock options needs to be better appreciated by staffers. If the choice was salary or stock, this was a time (post hoc reasoning) for better pay. I feel a duty of care was missed, but perhaps I misunderstand the obligations people who are "in the know" have towards employee-investors.

'America is still the best country in the world to start a business and take risks'. Do you have any data to back this up? I'm purely curious. Note you didn't state, 'and make an insanely large sum of money there', so I wouldn't be surprised if there were many more countries where it would be a good choice.

'America has more freedoms than most of the world'. What is in parenthesis is a sweeping generalization and what are you defining as 'most of the world'.

I'm not even sure what you're getting at with the NATO statement in relation to social mobility.

I'd just like to point out one thing I've noticed quite a bit and would love Europeans to chime in - that is - European exceptionalism. We, Americans, were known for American exceptionalism but that has eroded to a point where I haven't heard a single good thing about America in the last decade or so. We're shameful and contemptful of our nation. Slightest positive thing is considered nationalistic and right-wing, so we've become accustomed to similar mindset as the Germans post-WWII with regards to nationalism.

But, I am seeing some rise of European exceptionalism and wonder if things have changed over in Europe? Is it more united? Even small things like '.eu' domain is proudly used. I'd be damned if I use '.us' domain. Just a small example of many.

Social mobility is very different than economic mobility. It's not hugely difficult to earn six figures in the US if you're committed, work hard, and pick a good field. Heck, I did it without any college.

Social mobility is a different story. I was raised in a rural area, which is essentially a social class of its own. Since becoming an adult, I've found myself gravitating towards working-class people. I like the bluntness, the awareness of real issues, and the family values. I make more money than many of the yuppies who live a mile away, but socially, I'm several rungs "below" them.

I could get a nice haircut, mow my lawn properly, get divorced, and fit right in, if I chose to, but I don't want to. I think you'll find many lower-class Americans wouldn't, even if they knew how to.

Edit: by "Working class", I mean blue-collar and not wealthy. The salary cap is a little higher than the traditional definition, but I think it's a more accurate representation of middle America.
Actually they do. Without naming names, let's assume two populations, A and B.

A-Females are willing to marry B-Males, but B-Females are not willing to marry A-Males. This creates lots of abundance for B-Males and lots of scarcity for A-Makes.

As for jobs, in theory they can always be created a new. But in practice there are 1) very few people who can create jobs 2) external forces that might prevent new jobs from being created

Smoothed U.S. Recession Probabilities (1 month later)
Last month, a post titled “U.S. Recession Probabilities September 2021: 44% (stlouisfed.org)” generated some good discussion on Hacker News [1]. It now being December, I thought it would be interesting to check the updated forecast [2]. I was pleasantly surprised to find that the probability had plummeted. But furthermore, it was very interesting to see that the retroactive probabilities in September had dropped below 3%. I know many of you are interested in analyzing time series, and thought this was an interesting case study on the role of smoothing!

The shoelace machine gun is essentially non-useable for any real form of attack. It’s stupid & a straw man to bring up imo.

Congratulation!

Building a marketplace to sell something (Apps, courses, clothes, food, ...) is a very challenging problem.

I am an App developer who sales app in Google Play. The only thing I am concerning is, how much users are Google Play (marketplace) is gonna to bring to me? Rest of the concern factors are secondary to none.

Even if Google Play choose to charge higher fee, or providing a more crappy publishing tool, I still will stay with Google Play. Because I know if I try to sell my Android app elsewhere, I will get 0 customer.

Good luck to your venture!

I speedcube, and deliberate practice is extremely important. I also code, and deliberate practice doesn't do much in that area.
I need to have a feel for the code, understand what chunks of code do without having to read every line. That's tacit knowledge.

Maybe the difference could be explained with racecar driving. Driving the track correctly, hitting apexes, downshifting at the right moment; that's deliberate practice.

Knowing your car, understanding what a particular vibration means, feeling when you're approaching your traction limit, knowing that your engine is weak from 4-5k RPM, that's tacit knowledge.

Deliberate practice can foster tacit knowledge, however. Going through the motions opens your mind up to understanding what's going on behind the relatively simple task you're performing.

> America is still the best country in the world to start a business and take risks.

Not convinced. Serious illness can happen to anyone at any time, especially under the stress of running a business, and America has one of the weakest safety nets for a developed country.

> America still has more freedoms (speech especially) than most of the world.

The First Amendment is a great thing, but it can't maintain a culture of free speech on its own. The US's at-will firing (particularly combined with employer-dependent healthcare) means many Americans find it harder to express their views openly than people in other countries.

> Europeans don't give us enough credit. And they're replete with their own crises to always be pointing the finger.

European countries argue a lot, but there's a deep mutual respect underlying it. A willingness to reflect and see what other countries are doing better is vital in the long run.

> We're optimists, but the media is telling us not to be. They want us to yell at each other and drive ourselves into the dirt.

There's definitely a strain of hair-shirt criticism that's more interested in wallowing in self-denigration than making things better. But acknowledging the problems is important too.
> I would caution against using the existence of the Fangyan as firm evidence of a single language intelligible across Han China.

This is a good point. In particular it's a bit difficult to evaluate how much of 通語 was aspirational vs reality, especially as we don't have good documents outlining what the process of learning Chinese was like, but it clearly reflects a desire for a lingua franca (rather than it being a completely foreign concept). But it is clear that as soon as we have outside observers who are learning Chinese for the first time (an extremely valuable resource for tracking uniformity of language!), that at various times in China's history there was a single lingua franca.

E.g. Ricci says this, which is pretty much a direct refutation of the original article's point that a unified lingua franca was a 20th century invention,

> The Chinese have different languages in different provinces, to such an extent that they can not understand each other... The Chinese also have another language which is like a universal and common language...[much later] With all the varieties of languages, there is one that we call cuonhoa [官話], that is to say, the forensic language (lingua forense); it is used in audiences and tribunals; and, if one learns this, he could use it in all the provinces; in addition, even the children and women knew enough of it to be able to communicate with the people of another province. [Excerpted and translated by Paul Yang in The Portuguese-Chinese Dictionary of Matteo Ricci: A Historical and Linguistic Tradition, Proceedings of 2nd International Conference on Sinology, pg. 198-199]

Even allowing for the fact that Ricci is almost certainly experiencing some sort of selection bias (probably mainly talking to people with a certain amount of educational background), it's a pretty clear statement of a single language used across all of Ming China that superseded regional languages.

> Even the received literature of the Han Dynasty and Northern and Southern Dynasties is rich with extremely rare words and hapax legomena which may speak to a great regional diversity of language (there's other reasons for this too of course).

The whole post-Han pre-Tang time period is a bit of a crazy minefield to get through from a language perspective because of political (and consequently linguistic) disunity. There's also a bit of craziness in the Qing with competing standards (the old Ming Mandarin standard based off the Nanjing standard and the Beijing Mandarin standard, the competition extended up all the way into Beijing itself!) that also lead to a significant amount of fragmentation (and why e.g. there was a perceived need to make what would become the 老國音).

I don't mean to say that there was always a standardized, unified language, but I do mean to say that the idea of having one is very ancient, and convincing evidence that one was created and basically "worked" is also much older than the 20th century.
> If they're willing to fill-out some forms.

How does that part work in practise? Are these forms something someone from a poor uneducated background can actually realistically fill out?

The way I see it many Americans I had the chance to talk with either take a gamble on their health or they spend not unsignificant time and energy to find their ways through the system. The first choice can turn out just fine, or (in many cases) completely catastrophic. The second choice takes away time and resources that could have been spent somewhere else.
