The modularity of DAC systems implies that costs for CO2 removal might drop 90% to 95% over a couple of decades, just like the recent cost declines for other modular solutions such as wind turbines, solar panels and lithium-ion batteries.

Unlike other pollutants, what matters with carbon dioxide isn’t the location of its release but the total atmospheric accumulation. Releasing greenhouse gases in industrial corridors and then removing them from the atmosphere in remote locations has essentially the same net effect as if the carbon wasn’t emitted in the first place. That means we can deploy DAC systems wherever the energy for their operation is cheapest, ecosystem impacts are lowest, and the economic activity would be welcome.

A solar microgrid, which generates, stores and distributes clean energy to homes and facilities in a local network, provides a strong answer to these needs and wants. It can integrate with the main electric grid or disconnect and operate autonomously if the main grid is stressed or goes down. The physical pieces—solar panels, batteries and inverters—have been improving for a while. What’s new and coming, though, is the ability to orchestrate these different pieces into agile electric grids.

For decades it was a symbol of freedom on Chinese controlled soil: every June 4, come rain or shine, tens of thousands of people would descend on Victoria Park in Hong Kong to commemorate the victims of the 1989 Tiananmen Square massacre.

Authorities in mainland China have always done their best to erase all memory of the massacre: Censoring news reports, scrubbing all mentions from the internet, arresting and chasing into exile the organizers of the protests, and keeping the relatives of those who died under tight surveillance.

In 2020, despite the lack of an organized vigil, thousands of Hongkongers went to the park anyway in defiance of the authorities. But last year, the government put more than 3,000 riot police on standby to prevent unauthorized gatherings -- and the park remained in darkness for the first time in more than three decades.

At a talk on ethical artificial intelligence, the speaker brought up a variation on the famous trolley problem, which outlines a philosophical choice between two undesirable outcomes.

Say a self-driving car is traveling down a narrow alley with an elderly woman walking on one side and a small child on the other, and no way to thread between both without a fatality. Who should the car hit?

To get a sense of what this means, suppose that regulators require that any public health content — for example, on vaccines — not be vastly different for politically left- and right-leaning users. How should auditors check that a social media platform complies with this regulation? Can a platform be made to comply with the regulation without damaging its bottom line? And how does compliance affect the actual content that users do see?

Twitter executives deceived federal regulators and the company’s own board of directors about “extreme, egregious deficiencies” in its defenses against hackers, as well as its meager efforts to fight spam, according to an explosive whistleblower complaint from its former security chief.

The complaint from former head of security Peiter Zatko, a widely admired hacker known as “Mudge,” depicts Twitter as a chaotic and rudderless company beset by infighting, unable to properly protect its 238 million daily users including government agencies, heads of state and other influential public figures.

Among the most serious accusations in the complaint, a copy of which was obtained by The Washington Post, is that Twitter violated the terms of an 11-year-old settlement with the Federal Trade Commission by falsely claiming that it had a solid security plan. Zatko’s complaint alleges he had warned colleagues that half the company’s servers were running out-of-date and vulnerable software and that executives withheld dire facts about the number of breaches and lack of protection for user data, instead presenting directors with rosy charts measuring unimportant changes.

Numerous other Osage had died suspiciously — the cause of death often cloaked behind alcoholic poisoning or wasting illness or as simply unknown. Despite evidence that the victims had been murdered for their oil money, the cases were never properly investigated. Moreover, they could not be linked to the same killer caught by the bureau. The history of the Reign of Terror was less a question of who did it than who didn’t do it.

even now, as their stories are being dramatized in a movie and shown in theaters across the country, there is a campaign in Oklahoma — this time with legislation — to deter the history from being taught in schools.

The Osage had these events seared in their memories. Yet most Americans had excised even the bureau’s sanitized account from their consciences. Like the Tulsa Race Massacre, which occurred during the same period, the Osage Reign of Terror was generally not taught in schools, even in Oklahoma

The experience of young users on Meta’s Instagram—where Bejar had spent the previous two years working as a consultant—was especially acute. In a subsequent email to Instagram head Adam Mosseri, one statistic stood out: One in eight users under the age of 16 said they had experienced unwanted sexual advances on the platform over the previous seven days.

For Bejar, that finding was hardly a surprise. His daughter and her friends had been receiving unsolicited penis pictures and other forms of harassment on the platform since the age of 14, he wrote, and Meta’s systems generally ignored their reports—or responded by saying that the harassment didn’t violate platform rules.

“I asked her why boys keep doing that,” Bejar wrote to Zuckerberg and his top lieutenants. “She said if the only thing that happens is they get blocked, why wouldn’t they?”

As soon as you hit Google’s territorial waters, you came under our jurisdiction, our terms of service. Our laws–or lack thereof–apply here. By boarding our self-driving boat you granted us the right to all feedback you provide during your journey. This includes the chemical composition of your sweat.

Unified logins let us get to know our audience in ways we never could before. They gave us their locations so that we might better tell them if it was raining outside. They told us where they lived and where they wanted to go so that we could deliver a more immersive map that better anticipated what they wanted to do–it let us very literally tell people what they should do today. As people began to see how very useful Google Now was, they began to give us even more information. They told us to dig through their e-mail for their boarding passes–Imagine if you had to find it on your own!–they finally gave us permission to track and store their search and web history so that we could give them better and better Cards. And then there is the imaging. They gave us tens of thousands of pictures of themselves so that we could pick the best ones–yes we appealed to their vanity to do this: We’ll make you look better and assure you present a smiling, wrinkle-free face to the world–but it allowed us to also stitch together three-dimensional representations. Hangout chats let us know who everybody’s friends were, and what they had to say to them. Verbal searches gave us our users’ voices. These were intermediary steps. But it let us know where people were at all times, what they thought, what they said, and of course how they looked. Sure, Google Now could tell you what to do.

“We learned so much about regulation with Google Health. It turns out, the government has rules about health records, and that people care about these rules for some reason. So we began looking around for ways to avoid regulation. For example, government regulation meant it was much easier to experiment with white space in Kenya than in the United States. So we started thinking: What if the entire world looked more like Kenya? Or, even better, Somalia? Places where there are no laws. We haven’t adapted mechanisms to deal with some of our old institutions like the law. We aren’t keeping up with the rate of change we caused through technology. If you look at the laws we have, they’re very old. A law can’t be right if it’s 50 years old. Like, it’s before the Internet

“The word ‘date’ should almost be stricken from the dictionary,” Ms. Silver said. “Dating culture has evolved to a cycle of text messages, each one requiring the code-breaking skills of a cold war spy to interpret.”

Raised in the age of so-called “hookup culture,” millennials — who are reaching an age where they are starting to think about settling down — are subverting the rules of courtship.

Instead of dinner-and-a-movie, which seems as obsolete as a rotary phone, they rendezvous over phone texts, Facebook posts, instant messages and other “non-dates” that are leaving a generation confused about how to land a boyfriend or girlfriend.

Hodgson approached the organisers of the California State Fair wine competition, the oldest contest of its kind in North America, and proposed an experiment for their annual June tasting sessions.Each panel of four judges would be presented with their usual "flight" of samples to sniff, sip and slurp. But some wines would be presented to the panel three times, poured from the same bottle each time. The results would be compiled and analysed to see whether wine testing really is scientific.

Results from the first four years of the experiment, published in the Journal of Wine Economics, showed a typical judge's scores varied by plus or minus four points over the three blind tastings. A wine deemed to be a good 90 would be rated as an acceptable 86 by the same judge minutes later and then an excellent 94.

Ekman had traveled the globe with photographs that showed faces experiencing six basic emotions—happiness, sadness, fear, disgust, anger, and surprise. Everywhere he went, from Japan to Brazil to the remotest village of Papua New Guinea, he asked subjects to look at those faces and then to identify the emotions they saw on them. To do so, they had to pick from a set list of options presented to them by Ekman. The results were impressive. Everybody, it turned out, even preliterate Fore tribesmen in New Guinea who’d never seen a foreigner before in their lives, matched the same emotions to the same faces. Darwin, it seemed, had been right.

Ekman’s findings energized the previously marginal field of emotion science. Suddenly, researchers had an objective way to measure and compare human emotions—by reading the universal language of feeling written on the face. In the years that followed, Ekman would develop this idea, arguing that each emotion is like a reflex, with its own circuit in the brain and its own unique pattern of effects on the face and the body. He and his peers came to refer to it as the Basic Emotion model—and it had significant practical applications

What if he’s wrong?

Each of these developments has made it easier to do one’s business without wasted time and energy — without friction. Each has made economic transactions quicker and more efficient. That’s obviously good, and that’s what Bain Capital tries to do in the companies it buys. You may employ a lazy brother-in-law who is not earning his keep. If you try to do something about it, you may encounter enormous friction — from your spouse. But if Bain buys you out, it won’t have any trouble at all getting rid of your brother-in-law and replacing him with someone more productive. This is what “creative destruction” is all about.

These are all situations in which a little friction to slow us down would have enabled both institutions and individuals to make better decisions. And in the case of individuals, there is the added bonus that using cash more and credit less would have made it apparent sooner just how much the “booming ’90s” had left the middle class behind. Credit hid the ever-shrinking purchasing power of the middle class from view.

e. If credit card companies weren’t allowed to charge outrageous interest, perhaps not everyone with a pulse would be offered credit cards. And if people had to pay with cash, rather than plastic, they might keep their hands in their pockets just a little bit longer.

preparing for a series of raids that would target for deportation hundreds of families who have flocked to the United States since the start of last year

images, pilfered from the restaurant’s social media pages and the personal accounts of friends who had “liked” Comet Ping Pong online. Those photos have been used across dozens of websites. Parents, who declined to talk publicly for fear of retribution, have hired lawyers to get the photos removed.

Musicians who have performed at Comet Ping Pong have been pulled in, too. Amanda Kleinman, whose band, Heavy Breathing, has performed there several times, deleted her Twitter account after the abusive comments became overwhelming. Similar comments have flooded her YouTube music clips

“We are at a dangerous place in American culture where a good percentage of people aren’t distinguishing what is a real news source based on real reporting and fact-checking and only reinforcing pre-existing ideas they have,” Ms. Kleinman said.

It misunderstands a new media world in which every story, and source, is at risk of being discredited, not by argument but by sheer force.

During the months I spent talking to partisan Facebook page operators for a magazine article this year, it became clear that while the ecosystem contained easily identifiable and intentional fabrication, it contained much, much more of something else.

I recall a conversation with a fact checker about how to describe a story, posted on a pro-Trump website and promoted on a pro-Trump Facebook page — and, incidentally, copied from another pro-Trump site by overseas contractors. It tried to cast suspicion on Khizr Khan, the father of a slain American soldier, who had spoken out against Donald J. Trump.

California’s Internet companies may have once dreamed of liberating China through technology, but these days they seem more willing than ever to play the Communist Party's game

"This is a restoration of the Cultural Revolution or another historical retrogression," said another.

The Washington Post is one of many Western newspapers that carries a regular paid supplement by China Daily, another Communist Party mouthpiece.

Live free or die: This is the maxim of our age. But the freedoms we celebrate are particular and limited. We fetishize the freedom of business from state control; the freedom not to pay taxes; the freedom to carry guns and speak our minds and worship whom we will. But despite, in some cases because of, this respect for particular freedoms, every day the scope of our lives appears to contract.

Half a century ago, we were promised that rising wealth would mean less work, longer vacations and more choice

our working hours rise in line with economic growth, and they are now governed by a corporate culture of snooping and quantification, of infantilizing dictats and impossible demands, all of which smothers autonomy and creativity. Technologies that promised to save time and free us from drudgery (such as email and smartphones) fill our heads with a clatter so persistent it stifles the ability to think.
