Robert Merton and the effect of time on portfolio choice - Buttonwood
Say, a young person’s human capital, which determines his future earnings, is 90% of
his lifetime wealth, with the balance in stocks. And say that for an almost-retired
person the proportions are reversed. If the stockmarket crashes by 40%, the young
person has lost only 4% of his wealth. But the nearly retired person has lost 36%,
which is much more serious. For older people, having all their financial wealth in
stocks is not a sensible risk to take, says Mr Merton. Human capital is low-risk. If you
have lots of it, you can take more financial risk.

曲卫国 | 2019复旦毕业典礼的发言

这些年的毕业典礼,我每次都反复絮叨非正式版的民间复旦校训:自由而无用。遗憾的是,翻看前几次的发言,我发现我的心情一年比一年沉重。2017年我主要谈的是无用,non-instrumental。2018年我发现有必要对于自由好好地思考一番,因为说到自由,大家似乎更关注自己的自由权利。

The Perfect Storm Confronting Xi Jinping

China, however, has been a net food importer since at least 2007. This includes both grains and soybeans, central pillars of the Chinese diet. This is partly due to the growing need for animal feed, as China’s livestock production has expanded to meet increasing demands from a wealthier population.

“Experts report that there is a high probability that the pest will spread across all of China’s grain production area within the next 12 months.” There is no natural predator in China that feeds on the fall armyworm, nor are there any registered pesticides in China to counter it.

從這個父親節,每天多花50分鐘,開啟家中性別平等之路
那么,该如何走出迈向平等的第一步呢?报告给出的宏观方案包括五个方面:国家层面的法律与政策制定;社会层面的性别规范;家庭层面的支持;夫妻之间的磨合以及男性自身的投入。那男性该如何投入呢?就是这么简单——每天投入50分钟。减少一顿晚饭的应酬,少睡一会懒觉,戒掉一盘游戏,而用于参与家务劳作。男性每天增加50分钟,女性相应就能减少50分钟,两性的无薪家务劳作时间便达到了各占50%的比例。

The English Word That Hasn’t Changed in Sound or Meaning in 8,000 Years - Facts So Romantic - Nautilus

The English word honey is madhu in Sanskrit and myod in Russian. Sanskrit and Russian haven’t shared a common ancestor since Indo-European, so these words had to come from the same source. (There are also the words mead in English, met in German and mjød in Danish that refer to an alcoholic drink made from honey.)

The fact that those distantly related Indo-European languages had almost the same pronunciation of a single word meant that the word—and the concept behind it—had most likely existed in the Proto-Indo-European language. “If they had a word for it, they must have lived in a place where there was salmon,” explains Guy. “Salmon is a fish that lives in the ocean, reproduces in fresh water and swims up to rivers to lay eggs and mate. There are only a few places on the planet where that happens.”

In reconstructed Indo-European, there were words for bear, honey, oak tree, and snow, and, which is also important, no words for palm tree, elephant, lion, or zebra. Based on evidence like that, linguists reconstructed what their homeland was. The only possible geographic location turned out to be in a narrow band between Eastern Europe and the Black Sea where animals, trees, and insects matched the ancient Indo-European words.

How to Mount Removable Drives and Network Locations in the Windows Subsystem for Linux
Network locations can be mounted in one of two ways. If you map a network drive to a drive letter, you can mount it using the same options as above. This would give you an opportunity to easily sign into the network share and enter your credentials in File Explorer. For example, if your mapped network drive is F:, you could run the following commands to mount it:

sudo mkdir /mnt/f

sudo mount -t drvfs F: /mnt/f

From tea to opium: how the Scots left their mark on China | Aeon Essays
Like their 18th-century predecessors, Jardine and Matheson financed Britain’s lucrative tea trade in Canton by moving their clients’ money from India to China. Instead of transferring these fortunes through a variety of legal Indian and Southeast Asian commodities, namely cotton, pepper, wood, tin and saltpetre, as had been done in the past, the Scottish traders relied increasingly on a contraband product: Indian opium. In defiance of the laws of China they, along with private traders of different nationalities including Americans and Indian Parsis, smuggled tens of thousands of chests of opium into China each year during the first half of the 19th century.

In 1848 and again in 1849, Fortune travelled in full disguise, including the traditional Qing dynasty hairstyle with a shaved hairline and long braid, deep into the countryside of Zhejiang, Anhui and Fujian provinces. He was searching for the finest tea plants in China. Having acquired thousands of specimens and seeds, he shipped them all, carefully packed in airtight glass cases, from Hong Kong to the East India Company’s Botanical Gardens in Calcutta. From there, they went further, to the Company’s gardens in the Himalayas.

Scots played an outsized role in the intertwined trades of tea and opium, giving rise to social, economic and cultural developments that changed the macro relationship between Britain and China as well as everyday cultural practices and patterns of sociability.

When British consumers began sweetening their Chinese tea with Caribbean sugar, these two commodities, one from the East Indies, the other from the West, reinforced one another. The result was new fuel for the industrial revolution. In addition to coal, sugary tea made the revolution possible by helping British workers endure inhumanely long shifts in the textile factories of the industrial North.

News | ABC Dataset
We introduce ABC-Dataset, a collection of one million Computer-Aided Design (CAD) models for research of geometric deep learning methods and applications. Each model is a collection of explicitly parametrized curves and surfaces, providing ground truth for differential quantities, patch segmentation, geometric feature detection, and shape reconstruction. Sampling the parametric descriptions of surfaces and curves allows generating data in different formats and resolutions, enabling fair comparisons for a wide range of geometric learning algorithms. As a use case for our dataset, we perform a large-scale benchmark for estimation of surface normals, comparing existing data driven methods and evaluating their performance against both the ground truth and traditional normal estimation methods.

What's not happened since May 35, 1989 | The Japan Times
Now in Beijing everybody feigns ignorance. I don’t blame those ordinary Chinese interviewed on the streets who unanimously said, “I don’t know about it.” Their behavior isn’t wrong; it’s politically correct. What was wrong were the views of those of us in the West who dreamed a dream about China after June 4.

No civil society developed in China, although we thought in the late 1990s that the veterans of the 1989 Tiananmen incident would remain in the Communist Party and would eventually change the system from the inside toward democratization. We were wrong again. It’s time for us to stop our wishful thinking and become more realistic.

Opinion | Thirty Years After Tiananmen: Someone Always Remembers - The New York Times
This view is not limited to a few dissidents or foreign scholars, people out to make China look bad or who just can’t let bygones be bygones. The memory of Tiananmen is also being kept alive by people in China who believe that a government that uses force to stay in power is illegitimate.

History is also written with the smallest of gestures. Every spring I make a small trip to the Babaoshan cemetery in the western suburbs of Beijing to pay respects to two victims of the Tiananmen Square massacre
Four lines of the poem inscribed on the back of Xuehan’s tombstone explain, in a code of sorts, both the cause of his death and Xu Jue’s ritual:

Eight calla lilies
Nine yellow chrysanthemums
Six white tulips
Four red roses

Eight, nine, six, four. Year, month, day. June 4, 1989.

Two years ago, Ms. Xu died of cancer, at 77. Both years since, I’ve made the trip to the graves, thinking someone ought to put out the flowers. Each time, the 27 flowers were already there, tied in a neat bundle. Someone remembered. Someone always remembers.

Neuer Windatlas für Baden-Württemberg vorgestellt
Plus précisément: dans l'ancien atlas des vents, les emplacements par exemple de 5,5 m / s en moyenne annuelle (hauteur du moyeu de 140 m) étaient considérés comme appropriés. Les emplacements avec une densité éolienne moyenne d’au moins 215 W / m2 (hauteur du moyeu 160) devraient être considérés comme appropriés dans le nouvel Atlas. Cela correspond - converti à l'ancienne base d'imposition - à une vitesse annuelle moyenne du vent de 5,65 m / s à 5,9 m / s à 160 m au-dessus du sol. Cette nouvelle valeur d'orientation pour les zones appropriées - au moins 215 W / m2 - est recommandée comme base future pour l'évaluation par les autorités de planification et les autorités.

Le nouvel atlas éolien a coûté environ 218 000 euros.

The New Tiananmen Papers
It is not clear who, exactly, attended the Politburo meeting. But at least 17 people spoke, and each began his remarks with the words “I completely agree with” or “I completely support,” referring to Deng’s speech and Li’s report. All agreed that the student demonstrations had started as a “disturbance” (often translated as “turmoil”). They agreed that only when the demonstrators resisted the entry of troops into Beijing on June 2 did the situation turn into a “counterrevolutionary riot” that had to be put down by force. Each speech added personal insights, which served to demonstrate the sincerity of the speaker’s support for Deng’s line. Through this ceremony of affirmation, a divided party sought to turn the page and reassert control over a sullen society.

Ghosts of D-Day: The Civilian Casualties of the Battle of Normandy – BLARB
Most Germans had actually left Caen by June 6, a fact the Allies knew, prompting one British historian to call the bombing of Caen “close to a war crime;” there are also indications that some planes flew too high to hit their targets accurately. But my mother’s family was deeply grateful for the Allies. Living in Caen, they had suffered for four years under a regime of daily humiliations and threats, of near-starvation rations. None of the survivors I knew referred to the deaths of their loved ones as a crime. Caen was bombed in order to isolate the Germans by destroying lines of communication. To call that a war crime is to fall into the same black-and-white thinking that leads us to avoid mentioning civilian deaths in the first place.

Latin is dead—yet it also lives on - Johnson

A millennium or so after Cicero’s moans, in other words, Europeans spoke a range of tongues that were nevertheless related to each other and to Latin. What happened next in Italy had as much to do with politics as with the dynamics of languages. The contrast with its northern neighbour is instructive. France was unified by the conquest of territory spreading out from Paris; the conquerors brought Parisian speech with them, and that became “French”. A mighty state then did its best to teach that language everywhere, and to eradicate local variants.

Italy was unified far later, in the 19th century. “Italian” was thus created by the pen, not the sword. The 13th- and 14th-century works of Dante, Petrarch and Boccaccio were the peninsula’s most revered literature. So when, in the 16th century, Pietro Bembo sat down to write a grammar for the prestige language of their texts, he used their (by now rather old) Tuscan dialect as his model. In this way “Italian” was born—though Bembo titled his book simply “Writings on the Vulgar Tongue”. It soon spread to elites in other regions.

‘Overrun,’ ‘Outbred,’ ‘Replaced’: Why Ethnic Majorities Lash Out Over False Fears - The New York Times
That dynamic, sometimes known as a majority with a minority complex, is thought to be a major factor in the rise of right-wing populism in Europe, religious nationalism in Asia, and white nationalist terrorism in the United States and New Zealand.

When communal tensions broke out into the outright fighting known as the Troubles in the late 1960s, Northern Ireland’s Protestants were numerically, politically and economically dominant. But they were a minority on the island as a whole, feeding a sense of demographic peril.

Fears of existential, sectarian conflict can be self-realizing.

“more negative attitudes toward Latinos, blacks, and Asian-Americans” and “more automatic pro-white/anti-minority bias.”

Atrocities. Norms. Bicycles. See Where We’re Going With This?
But he didn’t do it alone. An entire team culture enabled Mr. Armstrong and his fellow riders to dope themselves to peak performance. The team’s doctor, its support workers, even riders’ wives were all enlisted to support and cover up the drug regimen. Team members from that time describe doping as a joint effort, something everyone approached with the same dedication and care that they applied to the rest of their training.

The pervasive doping, on that team and others, endangered riders’ health. It ruined lives. But if you read accounts by people who were involved, the most striking thing is that doping didn’t feel bad to them at the time. It felt more like a responsibility; one more thing that the team was doing to reach their ultimate goal of victory — and that everyone needed to help with.

Everyone on Lance Armstrong’s team knew that performance-enhancing drugs were banned in cycling. But those weren’t the rules that mattered. The internal rules, the norms for how people should behave to be a good member of the team, were the ones that held sway. And those norms said: Good members of this team do whatever it takes to win, so take the drugs.

In fact, even if you do know that your group is wrong, independence is still painful. In a 2005 study, fMRI scans of people contradicting their group’s statements showed increased activity in the part of the brain that processes emotional distress and fear, even when the subjects knew they were giving the correct answer to an easy question.

Those incentives, left unchecked, will shape group norms; those norms, in turn, will demand conformity. Participation in horrifying acts can become a condition of membership in good standing.

This Is How I Thread (Parallelism & Pointwise) | Another Fine Mesh
If parallelism is a tool, then that implies it is used to build something. What is that something? Put simply, optimized software. More specifically, parallelism is used to help computers solve bigger problems in less time. However, parallelism is not the only technique used to optimize code.

In the computing world, one name we give our workers is threads (short for threads of execution). When multiple threads are used in conjunction to solve a problem, this is called multithreading. If a problem can be subdivided so that multiple threads may execute concurrently to accomplish the same goal, then less time will be required to finish. However, subdividing problems is not always straightforward.

Fortunately, the algorithms used for many of the examine metrics in Pointwise fall into the “embarrassingly parallel” category.
So, what does it mean for an algorithm to be “embarrassingly parallel”? Simply put, it means that very little effort is required to divvy up a problem into parallel tasks. On top of this, little or no communication or synchronization among threads is required. Raw information is provided to each thread and each thread processes that data independently.
Unfortunately, cases like this are the exception. Data is rarely in such an amenable format, and threads often need to be highly interdependent to arrive at a solution.

However, closer inspection reveals that simply dividing the point data between threads for multithreaded execution will not provide sufficient isolation. This is because the algorithm requires that incident element data remain constant while a point is being positioned. If one thread modifies any point on a hull that another thread is manipulating, then results become inconsistent at best and corrupt at worst. The likelihood of such a scenario occurring increases dramatically as the number of threads increases.

Such organization can be achieved through the use of mesh partitioning. If the input mesh may be reliably and consistently partitioned into contiguous chunks, then each thread would be free to operate on its own chunk without fear of interfering with a concurrent thread.
The solution we adopted for this problem is to create a new, non-contiguous partition that only includes boundary points. This partition is then processed serially after multithreaded execution.

Of course, mesh partitioning presents overhead that a serial implementation
