Each of these moments — captured on video by a Tesla owner and posted online — reveals a fundamental weakness in Tesla’s “Full Self-Driving” technology, according to a panel of experts assembled by The Washington Post and asked to examine the videos. These are problems with no easy fix, the experts said, where patching one issue might introduce new complications, or where the nearly infinite array of possible real-life scenarios is simply too much for Tesla’s algorithms to master.

The Post selected six videos from a large array posted on YouTube and contacted the people who shot them to confirm their authenticity. The Post then recruited a half-dozen experts to conduct a frame-by-frame analysis.

The experts include academics who study self-driving vehicles; industry executives and technical staff who work in autonomous-vehicle safety analysis; and self-driving vehicle developers. None work in capacities that put them in competition with Tesla, and several said they did not fault Tesla for its approach. Two spoke on condition of anonymity to avoid angering Tesla, its fans or future clients.

“What can I even do?”Many people are feeling similarly defeated, and many others are outraged by the political inaction that ensues. A Muslim colleague of mine said she was appalled to see so much indifference to the atrocities and innocent lives lost in Gaza and Israel. How could anyone just go on as if nothing had happened?

inaction isn’t always caused by apathy. It can also be the product of empathy. More specifically, it can be the result of what psychologists call empathic distress: hurting for others while feeling unable to help.

I felt it intensely this fall, as violence escalated abroad and anger echoed across the United States. Helpless as a teacher, unsure of how to protect my students from hostility and hate. Useless as a psychologist and writer, finding words too empty to offer any hope. Powerless as a parent, searching for ways to reassure my kids that the world is a safe place and most people are good. Soon I found myself avoiding the news altogether and changing the subject when war came up

social networking sites create pressure to put time and effort into tending weak ties, and how it can be impossible to keep up with them all. Personally, I also find it difficult to keep up with my strong ties. I’m a great “pick up where we left off” friend, as are most of the people closest to me (makes sense, right?). I’m decidedly sub-awesome, however, at being in constant contact with more than a few people at a time.

the devolution of friendship. As I explain over the course of this essay, I link the devolution of friendship to—but do not “blame” it on—the affordances of various social networking platforms, especially (but not exclusively) so-called “frictionless sharing” features.

I’m using the word here in the same way that people use it to talk about the devolution of health care. One example of devolution of health care is some outpatient surgeries: patients are allowed to go home after their operations, but they still require a good deal of post-operative care such as changing bandages, irrigating wounds, administering medications, etc. Whereas before these patients would stay in the hospital and nurses would perform the care-labor necessary for their recoveries, patients must now find their own caregivers (usually family members or friends; sometimes themselves) to perform free care-labor. In this context, devolution marks the shift of labor and responsibility away from the medical establishment and onto the patient; within the patient-medical establishment collaboration, the patient must now provide a greater portion of the necessary work. Similarly, in some ways, we now expect our friends to do a greater portion of the work of being friends with us.

Trump slams outgoing CIA director Brennan after criticism over Russia threat | Fox News

President-elect Donald Trump blasted outgoing CIA Director John Brennan on social media Sunday after Brennan said Trump does not have a “full understanding” of Russia’s power and threat to the world.

He also suggested that Trump lacks a “full appreciation” of Russia’s aggression or about why President Obama imposed sanctions on the Kremlin for meddling in the 2016 presidential election.

As Donald Trump attempts to clamber to the Republican nomination over a still-divided opposition, there will be a lot of talk about how all these rules and quirks and complexities are just a way for insiders to steal the nomination away from him, in a kind of establishment coup against his otherwise inevitable victory.

We can expect to hear this case from Trump’s growing host of thralls and acolytes. (Ben Carson, come on down!) But we will also hear it from the officially neutral press, where there will be much brow-furrowed concern over the perils of party resistance to Trump’s progress, the “bad optics” of denying him the nomination if he arrives at the convention with the most delegates, the backlash sure to come if his uprising is somehow, well, trumped by the party apparatus.

Americans speak and think in the language of democracy, and so these arguments will find an audience,

We have found the “rotation” and “flex” models to be the best ways to combine online learning and offline teaching to meet the needs of students and schools. Unlike pure “face-to-face” teaching, these models integrate technology into the core instructional time, with greater personal attention given to students than in purely online environments.

Rotation: Lab Student groups rotate between traditional classroom instruction and online instruction in a computer or learning lab Lab monitored by an instructional aide rather than certified teacher.

The rancor is due, perhaps, to a fundamental confusion about what crowdfunding really is. On one hand, a backer is not a customer, because the product does not exist yet and may never

On the other hand, though, neither is a backer an investor, even if many of ZPM’s backers insisted they be treated as such. A Kickstarter pledge does not buy a portion of a company. Backers do not sit on the board; they are not enfranchised to review the company’s audited financials. Investors’ interests, at least ideally, are aligned with those of the company, whereas nothing in the crowdfunding relationship ties a backer to the company for the long term. Moreover, the last thing Kickstarter wants to deal with is S.E.C. regulations.

Kickstarter’s founders hardly imagined that a situation like this would arise. Neither was a technologist — Perry Chen, now 38, was an artist and gallerist, and Yancey Strickler, 36, was a music journalist — and although several of their recent hires have engineering backgrounds, they continue to see Kickstarter as something of an arts institution

Ukraine’s president has warned his army to be ready to repel a “full scale” Russian invasion, as fears mount of a return to all out warfare in eastern Ukraine.

At least 26 people were killed and dozens wounded on Wednesday when Ukrainian government forces and Russian-backed separatists fought a fierce battle on the outskirts of the separatist stronghold of Donetsk on Wednesday, in the most serious bout of fighting since a haphazardly observed ceasefire came into force in February.

Mr Poroshenko claimed there were already 9,000 Russian troops in separatist-held territory inside Ukraine, and said their was a “colossal threat” that Russian-backed forces would launch large scale operations in the near future. Russia denies deploying troops to east Ukraine.

All told, some fourteen million people are estimated to have died as a result of these atrocities; to put this number into context, it is two million more than the total number of German and Soviet soldiers killed in battle and over thirteen million more than American losses in all of its foreign wars combined.

The Holocaust was a unique historical event, the causes of which were distinctive. But it’s precisely because it occurred alongside other wide-scale horrors that Snyder is right to “test the proposition that deliberate and direct mass murder by these two regimes in the bloodlands is a distinct phenomenon worthy of separate treatment.”

Both ideologically and practically, Stalinism gave rise to Hitler. This was thanks to Soviet communism’s absolutist and totalitarian nature, which gave Hitler all the evidence he needed that nothing less than the full militarization of society was required to confront the eastern menace. Similarly, Stalin’s paranoid worldview directly contributed to policies which only emboldened Hitler. Stalin instructed German communists to treat their Social Democratic countrymen as “social fascists,” leading to fractures on the German left that ultimately gave way for Hitler’s ascent. This hothouse geopolitical environment created, as Hobsbawm would later put it, an “Age of Extremes.”

Conservatives — with the backing, I have to admit, of many economists — normally argue that the market for labor is like the market for anything else. The law of supply and demand, they say, determines the level of wages, and the invisible hand of the market will punish anyone who tries to defy this law.

Specifically, this view implies that any attempt to push up wages will either fail or have bad consequences. Setting a minimum wage, it’s claimed, will reduce employment and create a labor surplus, the same way attempts to put floors under the prices of agricultural commodities used to lead to butter mountains, wine lakes and so on

Pressuring employers to pay more, or encouraging workers to organize into unions, will have the same effect.

In 46 percent of all two-parent households, both parents work full-time, according to Pew, up from 31 percent in 1970.

The share of households with a mother who stays home has declined to 26 percent from 46 percent.

working parents are the new norm. Sixty percent of children now live in households where all the parents at home work at least part time, up from 40 percent in 1965,

For months, worried parents in Flint, Mich., arrived at their pediatricians’ offices in droves. Holding a toddler by the hand or an infant in their arms, they all have the same question: Are their children being poisoned?

To find out, all it takes is a prick of the finger, a small letting of blood. If tests come back positive, the potentially severe consequences are far more difficult to discern.

That’s how lead works. It leaves its mark quietly, with a virtually invisible trail. But years later, when a child shows signs of a learning disability or behavioral issues, lead’s prior presence in the bloodstream suddenly becomes inescapable.

he thinks John McCain questioning his citizenship is an indication that the political establishment is in "full panic mode,"

"Everybody knows John McCain is going to endorse Marco Rubio."

The stability (and even monotony) associated with German politics under Ms. Merkel appears to be coming to an end. Her looming retirement marks a deepening crisis of the German political system that threatens not just the future of the country, but of the European Union.

Thirty years later, this society has vanished. Average real incomes declined for nearly 20 years beginning in 1993. Germany not only grew more unequal, but the standard of living for the lower strata stagnated or even fell. The lowest 40 percent of households have faced annual net income losses for around 25 years now, while the kinds of jobs that promised long-term stability dwindled.

on the surface Germany appears to be an economic success story. Its G.D.P. has grown consistently for nearly a decade; unemployment is at its lowest since reunification in 1989. In amassing trade surpluses, Germany has enjoyed several advantages: an advanced manufacturing sector; the ability to get primary products and services from other members of the European Union; and being in the eurozone, which effectively gives the country a devalued currency, making its exports more attractive.

John F Kennedy, the 35th President of the United States, was shot dead on 22 November 1963. He was travelling in an open-topped limousine.

A week after Kennedy was killed, President Lyndon B Johnson set up a commission to investigate the case.

Around 88% of the records are open in full; 11% are open but with "sensitive portions" removed; and 1% are withheld in full.According to the 1992 law, all records must be published in full within 25 years, unless the president says otherwise.The deadline is Thursday.

SEOUL—With a clandestine trip to Beijing this week, North Korean leader Kim Jong Un has taken his first, tentative steps onto the world diplomatic stage.

Mr. Kim and his regime have sought legitimacy and recognition as a nuclear-weapons state as the country’s dilapidated economy has faced ever-tougher sanctions.

In Texas-sized congressional primaries, most GOP candidates run toward Trump

In several crowded Texas congressional primaries Tuesday, Republican candidates have decided that the best way to stand out is to stand squarely in Trump’s shadow — a campaign strategy that has been only slightly scrambled last week by the president’s sudden embrace of gun control and protectionist tariffs.

Isaac’s “Make America Like Texas” message is calibrated to couple Trump’s charisma to the more traditional Lone Star brand of small-government conservatism: “When I talk to people that move to Texas, I say, ‘Welcome to Texas, vote accordingly,’ because it’s not a mistake,” he said. “Our model works

cience is being turned against itself. For decades, its twin ideals of transparency and rigor have been weaponized by those who disagree with results produced by the scientific method. Under the Trump administration, that fight has ramped up again.

The same entreaties crop up again and again: We need to root out conflicts. We need more precise evidence. What makes these arguments so powerful is that they sound quite similar to the points raised by proponents of a very different call for change that’s coming from within science.

Despite having dissimilar goals, the two forces espouse principles that look surprisingly alike: Science needs to be transparent. Results and methods should be openly shared so that outside researchers can independently reproduce and validate them. The methods used to collect and analyze data should be rigorous and clear, and conclusions must be supported by evidence.

The Trump administration has been signaling for months that it plans to  implement conservative reforms to core federal welfare programs, including by allowing states to have work requirements for Medicaid. So it was no surprise on Thursday when the Centers for Medicare and Medicaid Services issued guidance for “state efforts to test incentives that make participation in work or other community engagement a requirement for continued Medicaid eligibility.”

So far, it’s unclear how widely adopted work requirements will be and how exactly states will implement them under CMS’s new guidance. On Friday, Kentucky was the first state to have its 1115 waiver creating work requirements approved by CMS. On Thursday, Verma noted that nine other states had already submitted waivers asking the federal government to approve incentives or requirements for some Medicaid beneficiaries. In addition to allowing strict job mandates, CMS will also allow requirements for “other community-engagement activities,” including volunteering, job training, and caregiving. (These rules only apply to specific adults; CMS carves out people with disabilities, the elderly, children, and pregnant women.)

Yet if states want work requirements to increase the health and self-sufficiency of Medicaid beneficiaries—their stated goal—most available data suggest they’ll fall short. As the Kaiser Family Foundation reported in 2017, most people on Medicaid who can work do work. Around 60 percent of adult enrollees have a job, and for the most part those who don’t report impediments in their ability to work. Even those who are not officially disabled often attest to having debilitating conditions—like severe back problems—that make full-time jobs difficult or impossible. Others may be in school, work as primary caretakers for loved ones, or may have retired.

The Sultan of Yogyakarta holds a powerful political and spiritual position on the Indonesian island of Java. He is manoeuvring to make his eldest daughter his heir, sparking a bitter feud, as the BBC's Indonesia editor Rebecca Henschke reports.

In Javanese culture, things are not said directly, but instead conveyed by symbolism.

The Javanese royal rule stretches back to the 16th Century and while the family is now Muslim like most Indonesians, the rituals they carry out are steeped in mysticism, a product of Hinduism, Buddhism and animism of the past.
