Why you shouldn't refrigerate tomatoes

...a tomato’s flavor — made up of sugars, acids and chemicals called volatiles — degrades as soon as it’s picked from the vine. There’s only one thing you can do now: Keep it out of the fridge.

Researchers at The University of Florida have found in a study published Monday in Proceedings of the National Academy of Sciences that when tomatoes are stored at the temperature kept in most refrigerators, irreversible genetic changes take place that erase some of their flavors forever.

Harry J. Klee, a professor of horticultural sciences who led the study, and his colleagues took two varieties of tomatoes — an heirloom and a more common modern variety — and stored them at 41 degrees Fahrenheit before letting them recover at room temperature (68 degrees Fahrenheit). When they looked at what happened inside the tomatoes in cold temperatures, Dr. Klee said the subtropical fruit went into shock, producing especially damaging changes after a week of storage. After they were allowed to warm up, even for a day, some genes in the tomatoes that created its flavor volatiles had turned off and stayed off.

Die-hard Clinton supporters are not that different from die-hard Trump supporters

I’ve been asking friends and family the last few days this question: “What could Clinton possibly do that would make you stay home, let alone vote for Trump?” (And for the people who say Trump is an exception, just substitute “George W. Bush” and pretend this was your choice.)

The answer so far: not much.

Imagine, for example, the power couple in Netflix’s House of Cards, who make it to the White House through years of murder and deception and scandals suppressed, but who have a sincere commitment to the issues. Imagine that were Hillary and Bill’s story, and it all came out this week: the hints of sinister murders and drug use and conniving. But still, no dent in the chances Hillary nominates a liberal supreme court judge, or pushes for climate change measures, or treats the 11 million illegals in the country in a humane way.

What I want to ask people is: Would you vote Trump, or even stay home and let Trump win in your state? For committed Democrats, I’m betting the crimes would have to be incredibly bad, and the proof incontrovertible. And the social media bubble would have to stick those unpleasant truths in your face rather than sow doubt about the truth or seriousness of any accusations.

Bizarrely, this makes me feel better about my country. You can look at your fellow Americans and not say “what a bunch of deplorables!”, but instead see a group of people who have a deep commitment to a set of principles and issues, and think their chances are better with Trump than Clinton, however much they might dislike him.

Muslim refugees: The future of Christianity in Europe?

When I first met Mattias in July at a refugee shelter just north of Berlin, he went by the name Mohammed. He had arrived in Germany from Iran the previous fall, along with thousands of other asylum-seekers—sometimes up to 10,000 arrived in a single day. After the German government assigned him to this shelter, he converted to Christianity. “I wouldn’t say I was a Muslim” before, he told me. “I didn’t go to a mosque for an entire year. Now I am going to church every week.” He expects it will take about three weeks to get off his church’s waiting list to be baptized. Perhaps once he’s more settled in Germany, he’ll be able to change his name legally to Mattias, his chosen Christian name. ...

We sat together in a sparse dormitory room at the shelter with three other Iranians who had converted from Islam to Christianity. They attend a Protestant church together...

Throughout Germany, the pews of churches like theirs are filled increasingly by asylum-seekers. ...

Muslim converts to Christianity that I spoke to in Germany cited the redemptive power of Jesus’s story, and disillusionment with Islam. It’s also worth noting the more earthly forces potentially at work: Germany does not grant refugee status to Iranians as easily as it does Syrians and Iraqis. ... Iranians seeking refugee status must prove that if they are sent home, they stand the risk of being persecuted for their beliefs. In Iran, that often means Christian converts. ...

A week after that meal, I visited Trinity Lutheran Church, which also hosts a large Iranian congregation. ...

Up the stairs and past the Iranian ushers, we poked our heads into the nave. There were few seats available, so we crowded into the choir loft along with the other stragglers. There appeared to be around 300 people in attendance, mostly Iranians, but my translator pointed out that a line of men seated behind us included Hazaras from Afghanistan—also current or former Shia Muslims—like the Iranians. Only a dozen or so in attendance appeared to be German. A woman in the front pews still wore a hijab. ...

[Pastor Gottfried] Martens said his congregation was “lucky” to have its pews filled with asylum-seekers from the Muslim world. Being around them, he said, brought meaning to his life. “It’s such a job to be together with these wonderful people who have risked so much for their Christian faith,” he said. “I can hardly imagine [working] in a normal German congregation anymore.” His church currently counts some 1,000 baptized Iranian and Afghan members with 300 on the waiting list, he said. Before someone is baptized, he must pass a kind of Christian entrance exam by taking classes on what it means to believe in Jesus Christ as the Messiah. It’s one way of making sure people aren’t just becoming Christian for the visa, to ascertain whether “they really understand what the Christian faith means,” Martens said.

Grant reviewers dislike ideas that are novel and close to their own expertise

...we designed and executed a grant proposal process at a leading research university in which we randomized the assignment of evaluators and proposals to generate 2,130 evaluator–proposal pairs. We find that evaluators systematically give lower scores to research proposals that are closer to their own areas of expertise and to those that are highly novel. The patterns are consistent with biases associated with boundedly rational evaluation of new ideas. The patterns are inconsistent with intellectual distance simply contributing “noise” or being associated with private interests of evaluators.

The Asian-American experience of otherness

To the Woman Who Told My Family to Go Back to China:

Maybe I should have let it go. Turned the other cheek. We had just gotten out of church, and I was with my family and some friends on the Upper East Side of Manhattan. We were going to lunch, trying to see if there was room in the Korean restaurant down the street. You were in a rush. It was raining. Our stroller and a gaggle of Asians were in your way.

But I was, honestly, stunned when you yelled at us from down the block, “Go back to China!”

I hesitated for a second and then sprinted to confront you. That must have startled you. You pulled out your iPhone in front of the Equinox and threatened to call the cops. It was comical, in retrospect. You might have been charged instead, especially after I walked away and you screamed, “Go back to your fucking country.”

“I was born in this country!” I yelled back.

It felt silly. But how else to prove I belonged? ...

You had on a nice rain coat. Your iPhone was a 6 Plus. You could have been a fellow parent in one of my daughters’ schools. You seemed, well, normal. But you had these feelings in you, and, the reality is, so do a lot of people in this country right now.

Maybe you don’t know this, but the insults you hurled at my family get to the heart of the Asian-American experience. It’s this persistent sense of otherness that a lot of us struggle with every day. That no matter what we do, how successful we are, what friends we make, we don’t belong. We’re foreign. We’re not American. It’s one of the reasons that Fox News segment the other day on Chinatown by Jesse Watters, with the karate and nunchucks and broken English, generated so much outrage.

My parents fled mainland China for Taiwan ahead of the Communist takeover. They came to the United States for graduate school. They raised two children, both of whom went to Harvard. I work at The New York Times. Model minority, indeed.

Yet somehow I still often feel like an outsider.

Steve Young's secret psychological frailties

The life story of [former San Francisco 49ers quarterback] Steve Young—“QB: My Life Behind the Spiral” by Steve Young with Jeff Benedict (Houghton Mifflin Harcourt), due out Oct. 11, but available for preorder now—is the rare sports book in which the heretofore pristine hero admits to some legitimate human scars. Young grew up so close to his parents that he could never attend sleepovers at friends’ homes, and the separation anxiety and homesickness was a real problem. He threatened to quit Brigham Young multiple times. Young had such performance anxiety that, before a 1993 game, he didn’t sleep for 36 hours, so petrified he was that he’d fail, and spent hours with a psychologist. In fact, that year, Young admits in the book that a depression specialist in San Francisco diagnosed him with separation anxiety and told him: “Never once have I seen an adult with the kind of separation anxiety that you have.”

This was months after Young was named the NFL’s Most Valuable Player, in 1992.

The progression of MBA career aspirations

Universum Global essentially asked MBAs to map out their most important career aspirations. Participants were asked to choose their top career goals immediately after finishing their MBAs, within 10 years of earning their MBA, and before they retire. They were given 12 goals to choose from and allowed to pick a maximum of three.

Some 93% of MBAs said they wanted to be “competitively or intellectually challenged” in their first job — a significant insight into how MBA recruiters should be portraying and messaging their companies. After that, 71% said they wanted to have a “secure and stable job”; more than half (58%) said they wanted to “lead or manage a team” in their first role. And 52% said they wanted to feel their work is “serving the greater good.”
Interestingly, just 13% said they wanted to “become wealthy” in their first job. ...

Within 10 years of finishing an MBA, though, a lot changes. Becoming wealthy jumps from 13% to 57% and ranks as the most important career goal. The second-most popular goal, at 51%, is being “seen as a technical or functional expert” in a field. Remarkably, being “competitively and intellectually challenged” drops from 93% to 5%. Meanwhile, having a secure and stable job drops from 71% to 18%, and starting a company zooms from 5% to 29%.

Not surprisingly, by career’s end, holding a C-suite position is the most popular important goal, with 48% of MBAs indicating they want to do so. Serving on a company or nonprofit board becomes the second-most important goal at 36%. Some intriguing, albeit obvious, trends surface across all three time frames. Achieving a healthy work-life balance drops from 48% at the beginning of a career to 41% within 10 years, then to 6% in the “before I retire” prompt. Being competitively and intellectually challenged plunges from 93% to 5% to 1% across a career; similarly, feeling that one’s work is serving a greater good drops from 52% at the beginning of a career to 26%, and then to 14%.

How drugs affected the course of World War II

At a company called Temmler in Berlin, Dr Fritz Hauschild, its head chemist, inspired by the successful use of the American amphetamine Benzedrine at the 1936 Olympic Games, began trying to develop his own wonder drug – and a year later, he patented the first German methyl-amphetamine. Pervitin, as it was known, quickly became a sensation, used as a confidence booster and performance enhancer by everyone from secretaries to actors to train drivers (initially, it could be bought without prescription). ...

In 1940, as plans were made to invade France through the Ardennes mountains, a “stimulant decree” was sent out to army doctors, recommending that soldiers take one tablet per day, two at night in short sequence, and another one or two tablets after two or three hours if necessary. ...

Was Blitzkrieg, then, largely the result of the Wehrmacht’s reliance on crystal meth? How far is [historian Norman] Ohler willing to go with this? He smiles. “Well, Mommsen always told me not to be mono-causal. But the invasion of France was made possible by the drugs. No drugs, no invasion. When Hitler heard about the plan to invade through Ardennes, he loved it [the allies were massed in northern Belgium]. But the high command said: it’s not possible, at night we have to rest, and they [the allies] will retreat and we will be stuck in the mountains. But then the stimulant decree was released, and that enabled them to stay awake for three days and three nights. Rommel [who then led one of the panzer divisions] and all those tank commanders were high – and without the tanks, they certainly wouldn’t have won.” ...

[Hitler's physician] began giving him a “wonder drug” called Eukodal, a designer opiate and close cousin of heroin whose chief characteristic was its potential to induce a euphoric state in the patient (today it is known as oxycodone). It wasn’t long before Hitler was receiving injections of Eukodal several times a day. Eventually he would combine it with twice daily doses of the high grade cocaine he had originally been prescribed for a problem with his ears...

The effect of the drugs could appear to onlookers to be little short of miraculous. One minute the Führer was so frail he could barely stand up. The next, he would be ranting unstoppably at Mussolini. ...

When the factories where Pervitin and Eukodal were made were bombed by the allies, supplies of his favourite drugs began to run out, and by February 1945 he was suffering withdrawal. Bowed and drooling and stabbing at his skin with a pair of golden tweezers, he cut a pitiful sight. “Everyone describes the bad health of Hitler in those final days [in the Führerbunker in Berlin],” says Ohler. “But there’s no clear explanation for it. It has been suggested that he was suffering from Parkinson’s disease. To me, though, it’s pretty clear that it was partly withdrawal.” He grins. “Yeah, it must have been pretty awful. He’s losing a world war, and he’s coming off drugs.”

Life as a bride in rural India

Upon reaching adulthood, they would be transferred to the guardianship of another family, along with a huge dowry that serves as an incentive to treat them well. The transfer is final. Once married, the new bride cannot return to visit her parents without permission, which is given sparingly, so that the bonds to her old home will weaken.

She must show her submission to the new family: She is not allowed to speak the names of her in-laws, because it is seen as too familiar, and in some places she is not allowed to use words that begin with the same letters as her in-laws’ names, requiring the invention of a large parallel vocabulary. Each morning, before she is allowed to eat, the daughter-in-law must wash the feet of her husband’s parents and then drink the water she has used to wash them.

Dhaka has the world's worst traffic

Dhakaites will tell you that the rest of the world doesn’t understand traffic, that the worst traffic jam in Mumbai or Cairo or Los Angeles is equivalent to a good day for Dhaka’s drivers. Experts agree. In the 2016 Global Liveability Survey, the quality of life report issued annually by the Economist Intelligence Unit, Dhaka ranked 137th out of 140 cities, edging out only Lagos, Tripoli and war-torn Damascus; its infrastructure rating was the worst of any city in the survey. ...

Yet on my flight to Dhaka I was told that the traffic in the city would be unusually light. For weeks, Bangladesh had been gripped by a hartal, a nationwide general strike and “transportation blockade.” ...

When my plane touched down I caught a taxi, which exited the airport into a roundabout before making its way onto the infamous highway. There, unmistakably, was a traffic jam: cars and trucks, as far the eye could see, stacked up in a configuration that bore no clear relationship to the lanes painted on the blacktop. ...

The distance from airport to hotel was eight and a half miles. The trip had taken two and a half hours. We wheeled into the hotel’s driveway and the cabby spun around to offer his verdict. “Some traffic,” he said. “Not so bad.”

Winning the lottery makes you like incumbent politicians more

Incumbent politicians tend to receive more votes when economic conditions are good. In this paper we explore the source of this correlation, exploiting the exceptional evidence provided by the Spanish Christmas Lottery. Because winning tickets are typically sold by one lottery outlet, winners tend to be geographically clustered. This allows us to study the impact of exogenous good economic conditions on voting behavior. We find that incumbents receive significantly more votes in winning provinces. The evidence is consistent with a temporary increase in happiness making voters more lenient toward the incumbent, or with a stronger preference for the status quo.

How to get a 3.5% riskfree interest rate for the next 20 years

If someone offered you a guaranteed 3.5% return for 20 years, you’d probably be tempted either to sign up right away or call the cops to arrest the guy for securities fraud.

But the guy offering this deal is Uncle Sam, and you should neither barge in nor run away screaming. You should look closer, because this offer from the U.S. Treasury is legitimate and highly attractive, although it isn’t right for everyone.

The government guarantees that if you hold Series EE savings bonds for 20 years, you will get back twice the amount of money you put in. That translates to a return averaging a whisker more than 3.5% annually. A 20-year U.S. Treasury bond, meanwhile, yields about 2.1%.

In today’s yield-starved world, a 3.5% return sounds almost like manna from heaven. Is there a catch? Of course there is — several, in fact.

First, and worst, that 3.5% return isn’t protected against inflation. And you will earn that rate only if you hold on for the full 20 years; until then, interest accrues only at the current rate of 0.1% annually. ...

You generally can’t redeem savings bonds the first year you own them and, if you cash out within the first five years, you will forfeit the last three months of interest. (That’s not much of a penalty at this point, though, at 0.025%.)

Finally, interest rates could take off between now and 2036, making that 3.5% look a lot less appealing. ...

And you can invest only $10,000 in EE savings bonds per Social Security number each year; if you’re married, you and your spouse together can buy $20,000.

Why Americans don't favor more redistributive taxation

[A] large share of survey respondents resist full equalization of after-tax incomes even when conventional optimal tax analyses would strongly recommend it. In a hypothetical situation meant to mimic the tax policy problem, between 50% and 95% of respondents choose not to fully offset inequality due to brute luck even when there are neither efficiency costs of redistribution nor differences in desert across individuals. These choices suggest that the two reasons why conventional optimal tax analyses tolerate after-tax inequality—the importance of encouraging effort and the possibility that some people "choose" to have low incomes—are not the only reasons why survey respondents, and perhaps Americans in general, accept it.

The second finding offers an explanation of the first: a large share of survey respondents prefer an alternative logic for taxation than that which is typically used in optimal tax analyses. The conventional logic stems from the use of a social welfare function that exhibits diminishing marginal social welfare of income. When presented with two possible justifications for their choices in the tax problem, between 62% and 79% of respondents prefer, instead of this logic, one tied to a centuries-old idea that Richard Musgrave (1959) named classical benefit-based taxation (CBBT). Under CBBT, taxes are assigned based on the benefit a taxpayer obtains from the activities of the state, with benefit being measured by the state's role in increasing the taxpayer's economic opportunities. In addition to being Adam Smith's first maxim of taxation, CBBT has a long history in public debate over taxes in the United States, from its use as a justification for the new personal income tax in 1913 to its use by presidents Franklin Delano Roosevelt and Barack Obama to advocate for progressivity. In that context, finding support for CBBT among the American public is natural, despite its absence from modern optimal tax theory.

What it feels like to die

For those who do die gradually, there’s often a final, rapid slide that happens in roughly the last few days of life—a phase known as “active dying.” During this time, [Stanford palliative care specialist James] Hallenbeck writes in Palliative Care Perspectives, his guide to palliative care for physicians, people tend to lose their senses and desires in a certain order. “First hunger and then thirst are lost. Speech is lost next, followed by vision. The last senses to go are usually hearing and touch.” ...

“As the brain begins to change and start to die, different parts become excited, and one of the parts that becomes excited is the visual system,” [director of UCLA Brain Injury Research Center David] Hovda explains. “And so that’s where people begin to see light.”

Recent research points to evidence that the sharpening of the senses some people report also seems to match what we know about the brain’s response to dying. Jimo Borjigin, a neuroscientist at the University of Michigan, first became intrigued by this subject when she noticed something strange in the brains of animals in another experiment: Just before the animals died, neurochemicals in the brain suddenly surged. While scientists had known that brain neurons continued to fire after a person died, this was different. The neurons were secreting new chemicals, and in large amounts.

“A lot of cardiac-arrest survivors describe that during their unconscious period, they have this amazing experience in their brain,” she says. “They see lights and then they describe the experience as ‘realer than real.’” She realized the sudden release of neurochemicals might help to explain this feeling.

Borjigin and her research team tried an experiment. They anesthetized eight rats, and then stopped their hearts. “Suddenly, all the different regions of the brain became synchronized,” she says. The rats’ brains showed higher power in different frequency waves, and also what is known as coherence—the electrical activity from different parts of the brain working together.

“If you’re focusing attention, doing something, trying to figure out a word or trying to remember a face—when you’re doing high-level cognitive activity, these features go up,” Borjigin says. ...

[A] half-dreaming, half-waking state is common in dying people. In fact, researchers led by Christopher Kerr at a hospice center outside Buffalo, New York, conducted a study of dying people’s dreams. Most of the patients interviewed, 88 percent, had at least one dream or vision. And those dreams usually felt different to them from normal dreams. For one thing, the dreams seemed clearer, more real. The “patients’ pre-death dreams were frequently so intense that the dream carried into wakefulness and the dying often experienced them as waking reality,” the researchers write in the Journal of Palliative Medicine.

Seventy-two percent of the patients dreamed about reuniting with people who had already died. Fifty-nine percent said they dreamed about getting ready to travel somewhere. Twenty-eight percent dreamed about meaningful experiences in the past. (Patients were interviewed every day, so the same people often reported dreams about multiple subjects.)

For most of the patients, the dreams were comforting and positive. The researchers say the dreams often helped decrease the fear of death. “The predominant quality of pre-death dreams/visions was a sense of personal meaning, which frequently carried emotional significance for the patient,” they report.

In patients’ final hours, after they’ve stopped eating and drinking, after they’ve lost their vision, “most dying people then close their eyes and appear to be asleep,” says Hallenbeck, the Stanford palliative-care specialist. “From this point on … we can only infer what is actually happening. My impression is that this is not a coma, a state of unconsciousness, as many families and clinicians think, but something like a dream state.”

Richer people spend less time on the Internet

Our dataset contains information for more than forty thousand primary home computers, or “home devices,” at US households in 2008 and more than thirty thousand in 2013. These data come from ComScore, a firm that tracks households over an entire year, recording all of the web sites visited, as well as some key demographics. ...

We find that higher income households spend less total time online per week. Households making $25,000-$35,000 a year spend ninety-two more minutes a week online than households making $100,000 or more a year in income, and differences vary monotonically over intermediate income levels.

The new college orientation: Microaggression edition

A freshman tentatively raises her hand and takes the microphone. “I’m really scared to ask this,” she begins. “When I, as a white female, listen to music that uses the N word, and I’m in the car, or, especially when I’m with all white friends, is it O.K. to sing along?”

The answer, from Sheree Marlowe, the new chief diversity officer at Clark University, is an unequivocal “no.”

The exchange was included in Ms. Marlowe’s presentation to recently arriving freshmen focusing on subtle “microaggressions,” part of a new campus vocabulary that also includes “safe spaces” and “trigger warnings.”

Microaggressions, Ms. Marlowe said, are comments, snubs or insults that communicate derogatory or negative messages that might not be intended to cause harm but are targeted at people based on their membership in a marginalized group.

Among her other tips: Don’t ask an Asian student you don’t know for help on your math homework or randomly ask a black student if he plays basketball. Both questions make assumptions based on stereotypes. And don’t say “you guys.” It could be interpreted as leaving out women, said Ms. Marlowe, who realized it was offensive only when someone confronted her for saying it during a presentation. ...

“What’s an environmental microaggression?” Ms. Marlowe asked the auditorium of about 525 freshmen. She gave an example. “On your first day of class, you enter the chemistry building and all of the pictures on the wall are scientists who are white and male,” she said. “If you’re a female, or you just don’t identify as a white male, that space automatically shows that you’re not represented.” ...

Another subset of microaggression is known as the microinvalidation, which includes comments suggesting that race plays a minor role in life’s outcomes, like “Everyone can succeed in this society if they work hard enough.” ...

But some students appeared slightly confused.

“When you use the term ‘self identify’ as a white woman, are you saying that you can choose your race?” one white male student asked.

“I’ll give you an example,” Ms. Marlowe said. “I went to a conference. I was talking to this man. I thought he was black. I was talking about diversity and social justice.”

“He said, ‘I’m Cuban,’ ” Ms. Marlowe told the crowd. “I assumed he was black because he was the same skin complexion as me, and the same type of hair.”

But, Ms. Marlowe said, while it is sometimes difficult to identify a person’s racial or ethnic background based on appearance, she does not believe that gives license to people like Rachel A. Dolezal, the white woman who claimed to be African-American while working for the N.A.A.C.P. in Spokane, Wash. “You can’t say you’re black if you’re not, historically.”

The student still seemed confused.

“Maybe we can unpack it afterward,” Ms. Marlowe told the student. “You want to come see me afterward?”

What it's like for a chef to get a bad NYT review

[David] Chang, knowing that the [New York Times] review would appear online the next day, slept fitfully, and woke in a bed that “was wet with sweat,” he told me later. Mid-morning, he went uptown, to discuss an expansionary media venture. During the meeting, he broke a promise to himself, and read the review on his phone. He then apologized to his hosts and left. He took a taxi to Momofuku Nishi, where he told his colleagues that they were experiencing something akin to a diagnosis of terminal cancer.

[New York Times critic Pete] Wells’s review began, “Searching for money, for love and for food, we strike bargains. We may be content with one for years until we begin to be shadowed by the suspicion that the terms aren’t working out in our favor anymore.” He protested, genially, about the restaurant’s noise and its uncomfortable seats, praised some dishes, and continued, “Too much of the cooking at Nishi is self-referential, inward looking, and so concerned with technique that you can’t help being conscious of it. In his early days, Mr. Chang used to serve the kind of food chefs like to eat: intense, animalistic, okay with messiness, indifferent to prettiness. Nishi serves the kind of food chefs cook to impress each other.” He gave the restaurant one star.

When I spoke to Chang that day, he talked almost without interruption for ninety minutes, in bursts of defiance, anger, and self-laceration. We met a few days later, and he was barely calmer, although self-awareness softened the effect. He apologized for whining; when he dreamed up conspiracy theories, he labelled them as conspiracy theories, and laughed dryly. (He came to accept, in time, that this article wasn’t planned with thoughts of discussing his restaurant.) When he said “Fuck him!” it was as often with resignation as with scorn. ...

“I can’t ever read that review again—I’ll get so fucking angry I’ll die,” Chang said. “I made a lot of that food! I tasted it! It was delicious. And . . . fuck!”...

Within weeks, the restaurant had abandoned its no-tipping policy and added a brunch menu.

Design secrets of medieval castles

A moat, which is a body of water that surrounds a castle, is often thought of as a water obstacle that had to be crossed; but this wasn’t the primary function of a moat. One of the biggest concerns of the inhabitants of a medieval castle or fortress was the fear that an invading army would dig tunnels under the fortification. This tunneling could either provide access to the castle or cause a collapse of the castle walls. A moat prevented this because any tunnel under the moat would collapse and fill with water. ...

Stairwells were often very carefully designed in Medieval Castles. Stairwells that curved up to towers often curved very narrowly and in a clockwise direction. This meant that any attackers coming up the stairs had their sword hands (right hand) against the interior curve of the wall and this made it very difficult for them to swing their swords. Defenders had their sword hands on the outside wall, which meant they had more room to swing. Another ingenious design of stairs was that they were designed with very uneven steps. Some steps were tall and other steps were short. The inhabitants, being familiar with the uneven pattern of the stair heights could move quickly up and down the stairs but attackers, in a dimly lit stairwell, would easily fall and get bogged down in the stairwells. This made them vulnerable to attacks and slowed their attacks down significantly.

How companies track your web browsing without cookies

In the ad tech industry, cookies are gradually being shunted in favor of fingerprinting. The reason that fingerprinting is so effective is that even if you have a device that you think is identical to the device of the person sitting next to you, there are going to be a number of differences in the behavior of your browser. The set of fonts installed on your browser could be different. The precise version number of the browser could be different. Your battery status could be different from that of the person next to you, or anybody else in the world. And it turns out that if you put all of these pieces of information together, a unique or nearly unique picture of the behavior of your device emerges that’s going to be relatively stable over time. And that enables your companies to recognize you when you come back. ...

[Editor’s note: Earlier in the interview, Narayanan had mentioned that the rate at which your battery depletes might be an identifier.] But let’s say you’ve got 41 fonts installed on your browser today. You come back in a week, maybe you have 43 fonts installed. But 41 of those are going to be the same as what they saw a week ago. And it changes slowly enough that statistically you can have a high degree of confidence. In the industry they call these things statistical IDs. It’s not as certain as putting a cookie on your browser, but you can derive a very high degree of confidence.

One man's nuclear fears helped create today's San Francisco housing crisis

In 1948, a federal housing bureaucrat named Paul Oppermann, trying to come to terms with the perils of the nuclear age, proposed a solution to the problem of protecting America’s cities from the bomb: empty them out preëmptively by encouraging the population to move to suburbs and small towns of fifty thousand or fewer. “No power in the world could afford to drop an atomic bomb on a city of 50,000 or less” is how the San Francisco Chronicle summarized the talk that Oppermann gave to a local planning organization. Plus, Oppermann explained, you get slum clearance into the bargain. The next year, Oppermann assumed office as San Francisco’s planning director.

The story of Oppermann—who did not send the residents of San Francisco packing but merely crippled growth with arcane lot-size rules and off-street-parking-space minimums—comes down to us via a San Francisco Bay Area cartographer, programmer, and amateur historian named Eric Fischer.
