While Michelin keeps its staff numbers secret, industry insiders say the guide cannot keep up with the thousands of restaurants in the guide

How many inspectors does it take to review the country’s best restaurants – a pinch, a baker’s dozen? For more than a century the answer has been kept secret by the world’s authority on good food: the Michelin Guide.

But the French tyre company’s famous hotel and restaurant reference book has been challenged by chefs, restaurant critics and diners, who question whether the guide has enough of its anonymous inspectors to adequately review and monitor the eateries that are included each year.

• Interim coach Trescothick hopes for unchanged lineup

• England secured series win over Pakistan on Sunday

Marcus Trescothick is determined to sign off as England’s interim head coach with a 100% record and has no plans to meddle with a winning formula in next week’s final Test of the summer, despite securing the series win by beating Pakistan at Lord’s.

Two successful games into a series, the most likely cause of a lineup change would be fatigue, but Pakistan have not forced England to toil unduly over their two wins – last summer the average India innings lasted 107.5 overs; this summer Pakistan’s figure is 43.3. Meanwhile winning the second Test on day four means the players have nine clear days before action resumes at Edgbaston.

The Swedish flag is still flying above the pale blue building overlooking the Atlantic in Liberia’s capital, Monrovia, but the doors of the embassy are now closed to visitors. On 31 August, the Swedish embassy in Liberia ends a presence in the country that dates back to 1961.

The billions of kronor of aid that Sweden pipes into the west African country will end on the same day, as sweeping cuts to Swedish development funding come into effect.

War on Gaza and violence in West Bank is playing out in the streets of Toledo, Ohio, where the Arab American community has flourished

From his office outside Toledo, Ohio, Thamin Tim Ridi opens his phone to livestream the scene outside the besieged house of his brother, Loui, thousands of miles away in the occupied West Bank.

This month, with his property at risk of being destroyed by Israeli settlers, Loui traveled from Ohio to his ancestral home in Qusra, south of Nablus, where his mother and other family members have been living in constant fear of attack.

Java-синтаксис на 8-битных микроконтроллерах? Без виртуальной машины?

Исторически в эмбеддеде правит Си. Но Си — это вечные malloc/free, утечки памяти, выходы за границы массива и дебаг с осциллографом.

Я разрабатываю vm5277 — монолитный тулкит и язык J8B с Java-подобным синтаксисом. Он компилирует строгий ООП-код напрямую в нативный, оптимизированный ассемблер.

Что под капотом:

Управление памятью: через Reference Counting (new без free и без Garbage Collector).

Полиморфизм интерфейсов: спрятан во Flash (без оверхеда в ОЗУ).

Типы данных: встроенный 16-битный примитив fixed (Q7.8) вместо тяжелого float.

Оптимизация: тотальный Dead Code Elimination (в прошивку идет только то, что реально вызвано).

Проект в стадии суровой Альфы. Код открыт на GitHub, десятки примеров (от мигания диодом до драйверов периферии).

Aaron Renn was in a good mood. And that was fair: It’s not every day that you get labeled the No. 1 “intellectual super influencer” for a major swath of the Trump-era right.

“It’s always good to have some independent validation of your work,” he told me.

A former partner at the consulting firm Accenture, he’s now best known for his writing on urban policy and the role of evangelical Christians (like himself) in American culture. His concept of the “negative world” — the idea that contemporary mainstream culture is inherently hostile to anyone taking evangelical principles seriously — has become influential enough to receive feature treatment in the New York Times.

Yet for anyone familiar with American politics, the idea that someone like Aaron Renn is in any way the No. 1 “super influencer” on the right might seem implausible. He’s not a social media warrior with the White House’s ear, like Laura Loomer or Chris Rufo. He’s not a household name like Tucker Carlson. He doesn’t run a big media outfit like Ben Shapiro. So where does Renn’s achievement come from, and what does it mean?

The source is a new report from the boutique risk analysis firm Baron Public Affairs LLC. Baron makes its money, in part, by advising corporate clients on how best to navigate the DC political environment to advance their interests. Its new report is an attempt to guide them through a specific subset of the right: the national-populist corner of the right-wing policy world that’s achieved greater prominence since 2016.

Baron’s report paints a fascinating picture of today’s conservatism, shining a light on some of its most thoughtful, relevant, and interesting quarters. Yet in doing so, the report also skates over divisions inside the group under consideration  — splits that matter immensely for the American right’s future.

The “super influencers,” explained

In its report, Baron compiled papers published by six right-wing think tanks and one right-leaning intellectual journal. They then used a proprietary research platform to comb through 29,181 citations to individual people in those papers, and assembled a list of the top 20 most cited names in their sample. These, in Baron’s estimation, are the “super influencers” who “most inform the policy leaders of the nationalist-populist movement,” the conservatives building intellectual scaffolding to support the GOP’s turn toward both economic and political nationalism. 

Baron did not publish the full list of 20 names (and did not respond to my repeated requests for comment). But alongside Renn, the most cited name in its sample, it revealed two other “super influencers” in an accompanying podcast: Brad Wilcox and Michael Lind. Both are revealing.

Wilcox is a sociologist at the University of Virginia and a senior fellow at the Institute for Family Studies, a think tank known for taking an unusually empirical approach to social conservatism. If you’ve followed Wilcox, whose work has often been relevant to our coverage at Vox, you’ve probably seen him offering charts, graphs, and regression analyses to defend his view that marriage is one of society’s most important and valuable institutions. His most recent book is titled, simply enough, Get Married.

Lind, by contrast, arguably isn’t a conservative at all. A longtime commentator on American politics, he began his career as a kind of left labor populist — hostile to mass immigration due to the same (empirically doubtful) fears about the harmful effects on native-born workers that once shaped Bernie Sanders’s views on the issue. 

Long critical of the cultural elitism of American liberals, Lind has drifted more and more toward writing for conservative outlets: becoming in effect, if not in self-identification, a real influence on the populist right. (He is not the only liberal on the list, which per Baron includes “two Biden-era White House officials and a writer who leads one of the more prominent tribes of the Left.”)

These three men — Renn, Wilcox, and Lind — reflect what Baron sees as the defining preoccupations of the “super influencers” more broadly.

Unlike previous generations of conservatives, the right’s new intellectuals aren’t especially interested in maximizing economic growth or projecting American power abroad (in fact, none of Baron’s top 20 were foreign policy experts at all). Instead, they’re overwhelmingly focused on different questions: how to reverse declining fertility rates, or the effect of trade competition with China on American cities and families. 

In our conversation, Renn suggested a uniting concept for the issues these writers cared about: “the social health of the nation.” By this, he meant things that couldn’t be fully captured by traditional economic metrics: whether Americans feel happy, whether they feel like they live meaningful lives, whether they feel like their families and communities are secure and stable. 

“There are these trends that don’t seem super healthy even if the GDP line continues to go up,” Renn says. “Those have been issues that weren’t part of Donald Trump’s initial set of issues, but are ones that have become widely talked about — even on the left.”

Though the preoccupations of the right’s new social thinkers may have arisen alongside Trump to challenge Reagan-era free-market conservatives, they themselves are not necessarily Trumpy. Befitting the fact that many have backgrounds in quantitative social science, and that some see themselves as liberals, they tend to be looking for answers beyond MAGA demagoguery. That’s true even though their research topics have some obvious appeal within MAGA spaces.

Super influencers against themselves

Baron’s report paints an appealing portrait of the modern right. Renn’s oeuvre is indeed fascinating, and Wilcox’s empiricism fosters a more serious conversation around social policy than the traditional culture war hysterics. More broadly, I think Baron is right that the sorts of issues that preoccupy these thinkers will indeed remain important for the right for quite some time.

But I think there’s a danger in treating this group as homogenous, or as representative of the right as a whole.

To see why, it’s helpful to go back to the report’s basic methodology — tracking citations in right-wing publications. Those publications were drawn from the following seven sources:

• American Affairs
• American Compass
• The Foundation for American Innovation (FAI)
• The Claremont Institute
• The America First Policy Institute (AFPI)
• The Center for Renewing America (CRA)
• The Heritage Foundation

These are extremely different outfits. Three of them — American Affairs, American Compass, and FAI — indeed overlap with the kinds of questions that Baron’s “super influencers” are interested in. The other four, by contrast, are MAGA more than anything else: Their mission, at least as currently constituted, is to mount an intellectual defense of the president’s worldview and/or develop policy ideas that might flesh out Trump’s inchoate impulses.

This isn’t necessarily relevant for Baron’s mission in advising clients on which influential voices deserve their attention. But for those of us interested in mapping the intellectual right, these distinctions are vital.

Indeed, by Baron’s own estimation, there is a significant difference between the kinds of people cited in reports by these two sub-groupings in its sample. The first grouping, Baron found, will regularly cite “heterodox liberals” like Lind who share some of their priorities; the second did not cite a single such liberal in any of the reports it surveyed. 

Thus, there actually isn’t one unified cadre of intellectual “super influencers” shaping the national-populist right. There are two distinctive groupings: one which influences the sorts of New Right outfits committed to their own ideological project, the other which influences reports released by MAGA appendages. While there is some overlap between those two groups, Baron’s own analysis suggests they are meaningfully distinct blocs.

This matters for the right’s future. In fact, it matters a lot.

Publications from the first three of Baron’s sources tend to be less hard-edged about partisan conflict; they engage with liberals quite a bit because they prioritize their long-term policy goals and are looking for coalition members who can help advance them. In their work, you can see some of the virtues the Baron report documents amongst the cited “super influencers” — empiricism, “genteel temperament,” a focus on distinctively 21st century social problems.

Work by the other four, by contrast, tends to paint American political divisions in apocalyptic terms. Claremont writers, for example, have famously described the 2016 election as “Flight 93” and declared that “most people living in the United States today — certainly more than half — are not Americans in any meaningful sense of the term.” They do not cite liberals approvingly because they see them as worse than political rivals: as villains, the authors of America’s ills, whose power must be crushed for the country to survive. 

“We are in the process of the second American Revolution, which will remain bloodless if the left allows it to be,” as Heritage president Kevin Roberts put it in an interview on Steve Bannon’s podcast.

One of the principal questions of the right’s looming post-Trump era will be whether it can move past this kind of zero-sum partisanship. The Baron report might lead one to be optimistic on that front: if Aaron Renn truly is the leading influence among the American right’s national-populist intellectuals, that portends a future where America’s warring political tribes can finally start to find common ground.

But I wouldn’t bet on it, at least not for some time now.

There are deep reasons why Trump, a human embodiment of rage and division, leads the Republican Party — and why some of the right’s top thought leaders are so loyal to him. So long as those reasons persist, the influence of more thoughtful “super influencers” on practical politics may be more limited than one might hope.

With millions of club shirts going to waste every season, a radical recycling rethink is needed

When Joanna Czutkowna buried a Manchester United jersey, a cotton T-shirt and a wool-cotton jumper in her Lancashire farm and dug it up a year later, the video went viral. The T-shirt had disappeared, apart from the seams (sewn with polyester thread), the jumper was 80% gone, but the United shirt remained – grubby but indestructible. (Insert joke here)

The big reveal was not a surprise, certainly not to Czutkowna, who has worked in textiles and sustainability for 20 years, but it was a reminder: a football jersey is not just for Christmas, or even the next hundred Christmases.

• Atlético say they will not allow Barcelona to buy Álvarez

• Jesus poised for Barça and Martinelli for Al-Hilal

Arsenal are running out of time to persuade Julián Álvarez to join them from Atlético Madrid after agreeing to sell Gabriel Martinelli, Gabriel Jesus and Fábio Vieira in deals collectively worth more than £70m.

Álvarez has his heart set on Barcelona despite Atlético’s insistence they will not sell to their La Liga rivals and returned to training on Sunday after being left out of their squad for the win over Sevilla. The Arsenal manager, Mikel Arteta, is understood to have spoken to Álvarez last week in an effort to persuade the former Manchester City forward to return to the Premier League and to have been informed the Argentina international wants only Barcelona.

Unions say ban will take time to enact, while president also wants under-15s social media ban as key legacy

French high schools are rushing to put in place a ban on mobile phones this week as Emmanuel Macron pushes for children to spend less time in front of screens.

Education unions warned that banning mobile phone use in lycées – where children are aged 15 to 18 – would be hard to implement quickly.

Death toll from unprecedented deluge of ice, rock, mud ​and debris now stands at more than 900. Plus, was it a mistake to take away Pluto’s planet status?

• Don’t already get First Thing in your inbox? Sign up here

Good morning. Rescue teams are working to reach hundreds of people feared trapped in the tunnels and underground areas of half a dozen hydropower projects in Nepal as more than 900 workers were reported missing after the devastating flash floods.

The death toll from the ⁠unprecedented deluge of ice, rock, mud ​and debris that crashed through valleys of Nepal on Wednesday last week has risen to 903 people, with 16 reported dead on the Tibet side of the border. More than 4,000 are missing in Nepal, with another 500 in Tibet. Hundreds of bodies, many unidentified, have been buried in shallow graves.

How large is the rescue operation? Nepal’s prime minister, Balendra Shah, said almost 21,000 security personnel were involved in the rescue operations, besides civilian workers and volunteers. China’s state-run CCTV reported that Beijing had mobilised more than 2,100 rescue workers. The Red Cross has ‌estimated that more than 90,000 people are likely to have been affected by the disaster, which China and some experts linked to the effects of the climate crisis.

Why has the disaster sparked a racism row in Australia? A slew of racist social media comments have been made towards missing Australians. Most of them were on pilgrimages, including to Mount Kailash in Tibet. Mainstream media outlets including News Corp, Channel 7, Channel 10 and Nine have been hit with highly offensive and discriminatory comments on Facebook articles identifying the missing Australians.

What has Donald Trump claimed US forces are doing? Hours after the attacks, the US president, Donald Trump, claimed in a social media post that Iran’s energy hub of Kharg Island was being “blown to smithereens” but gave no further details. The White House and ⁠the US defense department did not immediately respond to requests for comment. Attacking Kharg, which handled 90% of ⁠Iran’s oil exports before the war, would severely disrupt the Islamic republic’s energy trade and put huge pressure on its economy.

US trade representative Jamieson Greer has a level-headed reputation but commerce secretary Howard Lutnick and White House adviser Peter Navarro also have key roles

Having reportedly read Victor Hugo’s Les Misérables, in French, during a military tour of duty in Iraq, Jamieson Greer considered himself an unlikely target for accusations of francophobia.

But Donald Trump’s US trade representative, hitherto one of the president’s less high-profile cabinet members, found himself in that uncomfortable position amid the acrimonious collapse of bilateral trade talks with Canada that now threatens to degenerate into an all-out trade war between the two close trading partners whose economies are tightly intertwined.

Pedro Sánchez says two countries cooperating and accuses Israel and Russia of spreading fake news about migration

Spain’s prime minister, Pedro Sánchez, has said there is no evidence to suggest the Moroccan government was behind last month’s massive border crossing into Ceuta but accused Israel and Russia of spreading disinformation.

As many as 141 people are thought to have died trying to enter the Spanish enclave at the end of July. The influx of about 70,000 men, women and children unleashed a political crisis, a humanitarian emergency and reignited tensions within the EU over immigration.

Conservative leader sacks shadow chancellor Mel Stride and shadow foreign secretary Priti Patel

• Conservative reshuffle: who’s who in Kemi Badenoch’s top team?

Kemi Badenoch sacked her shadow chancellor, Mel Stride, and the shadow foreign secretary, Priti Patel, in a sweeping Conservative reshuffle on Monday, replacing Stride with Andrew Griffith, and Patel with Tom Tugendhat.

Stride, who had been shadow chancellor since Badenoch became leader, was widely seen among Tories as failing to make an impression at a time when Labour had been under pressure over the economy.

Привет! Я Максим Савченко, iOS-разработчик. Эта история началась с вопроса, как сделать живую форму в духе иконки Siri — и довольно быстро уехала в другую сторону: аттрактор Лоренца на сотнях тысяч, а потом и на миллионе частиц, где и расчёт, и отрисовка живут на GPU.

Вся схема держится на одной идее: состояние частиц на CPU больше не возвращается. Compute-шейдер читает один буфер, пишет в другой, render-pass сразу рисует результат, на следующем кадре буферы меняются местами.

В статье разбираю это по шагам: математика и выбор интегратора, ping-pong-буферы, compute/render-пайплайн, point primitives и additive blending. А в конце — GPU Frame Capture и замеры на физическом iPhone. Спойлер, который я сам не ожидал: RK4 в этой конфигурации оказался далеко не самым дорогим местом. Основная цена ушла в отрисовку и overdraw.

Если коротко: это не гайд «как нарисовать красивую картинку», а разбор того, зачем вообще лезть в Metal и где кадр упирается на реальном устройстве.

Debut director James Ross II shows promise in this gore fest, but the fear factor suffers from an overly complex plot

Sleep has been part of the horror genre repertoire since The Cabinet of Dr Caligari, and the anxieties around it are spiking as the “sleep economy” becomes a thing. This ambitiously structured gore fest about a woman suffering from waking nightmares comes with an all-black cast, but race isn’t a central preoccupation here. Instead, as night terrors burst the banks into reality, debut director James Ross II concentrates on maintaining an appropriately scrambled and claustrophobic experience – perhaps to the detriment of the fear factor.

On her 15th birthday, Riley (Jasmine Mathews) is paralysed in a waking/sleep state at her foster home, able to observe but powerless to intervene to stop a care worker going berserk. Since this massacre, Riley keeps a strict sleep protocol as an adult, making sure anyone under the same roof drops off before her, which apparently protects them from the malevolent presence invading her nights. Old foster home pal David (Stephen Barrington) accepts an invitation to the house where Riley’s dad murdered her mum, but gets the willies when a pallid demon begins manifesting in the small hours. It turns out that Riley’s boyfriend, Cam (RJ Brown), has been lax in letting her fall asleep before him – and now her resident succubus is on the loose again.

Divers join search teams scouring deep waters for ⁠any survivors, with eight people so far confirmed to have died

Nearly 20 people are still missing after a ferry capsized ⁠off northern Cyprus, killing at least eight, as divers join search teams scouring deep waters for ⁠any survivors.

The double-hulled ⁠ferry ​with 267 people onboard took in water and flipped over on Sunday just off the port city ⁠of Kyrenia, leaving survivors clinging to the upturned hull. They were rescued by passing vessels and members of the coastguard.
