Небольшой инженерный постмортем про то, как метрики качества тестов дружно молчали, пока пользователь не прислал скриншот с очевидной ошибкой. И почему ни строчное покрытие, ни мутационное тестирование этот класс багов поймать не могли в принципе.

У меня есть внутренний дашборд, который собирает список рабочих копий проекта (git worktree) и показывает по каждой последнюю активность. В какой-то момент пришло сообщение: «разные ветки, а последнее сообщение и время везде одинаковые». Я открыл дашборд — и правда: каждая копия отображалась пять раз подряд, с идентичными данными. При этом тесты были зелёные, строчное покрытие — сто процентов, а мутационный прогон по этому куску показывал 97,8%. То есть все три метрики, которым принято доверять, дружно сказали «всё хорошо».

• ICC exploring fixed windows for each format

• Continental championships among ideas up for debate

The International Cricket Council is exploring a radical overhaul of the global calendar with discussions surrounding multilateral series, the creation of continental championships, a World Club Championship for T20 franchises, fixed windows for each format and possible changes to the length of one-day internationals.

Talks between the 12 full members will take place at the ICC’s annual general meeting in Edinburgh on Wednesday as part of a strategic review being managed by the consulting firm McKinsey.

Huge parties take place when the national team play but people in Brazil cherish a good game, whoever is playing

The World Cup atmosphere, which, for many of us, is one of the most infectious feelings there is, has, in the US been confined to the stadiums, the surrounding streets and fan festivals. This has been played out before and comes as no surprise. Football has limited traction in North American culture.

This highlights how different it is being in the US to being in Brazil, where I am now after following the national team in North America. Football’s extremely important role in Brazilian culture explains why the national team at the World Cup is the centre of our universe.

Spain’s manager answers your questions on advice for Lamine Yamal, the hardest thing about being a coach and how the current team compares to the winners of 2010

“You’ve filtered these, right?” Luis de la Fuente asks, looking at the laptop of your questions on the table in front of him, and cracking up. He takes his seat on the third floor of the Cotton Bowl, Dallas, where Spain have just finished training ahead of their last-16 meeting with Portugal. Some of the players are still out there in the sunshine, in the place where Bebeto rocked the baby in 1994. It is the morning after that Cape Verde performance against Argentina. The World Cup is a creator of memories, pictures in the mind that never go. We all have one, or more.

“Because of what it means for Spain, it has to be [Andrés] Iniesta’s goal,” De la Fuente says. “It’s not very original but that’s the image of the World Cup for us. I would have been at home watching it. I have always been very into the national team. Whenever the Selección played, it was an event at my parents’ house. My parents would watch, my brothers and sisters, people would come round to watch. That’s in Haro, La Rioja. And then as a professional, wherever the game found me, I would watch it. I would enjoy every World Cup game, but especially the Spain ones. There are other images of the World Cup, but that’s the most powerful.”

Argentina’s captain leads the way for veteran strikers at World Cup. They have different styles, but all have shown their worth

I would be shocked if the record for the most goals scored by a player in a World Cup – Just Fontaine’s 13 in 1958 – is not broken this summer. That is how elite the world’s top forwards are. They are all pushing each other to keep scoring more. We are so lucky to be watching them at the same time.

I also believe, because of the skill set required to be a world-class, modern-day finisher, we are going to see more and more playing into their 40s, so much so that it may be possible that Lionel Messi and Cristiano Ronaldo could go to another World Cup.

After their frantic display against DR Congo, England head coach needs his side to remain composed in the Azteca cauldron

It was somehow in keeping with the bedlam that has gripped Mexico since Tuesday night when their team beat Ecuador to set up a World Cup last-16 showdown with England on Sunday. There was talk of an incoming storm, which is forecast to bring the risk of flooding and affect a game talked up as arguably the biggest in Mexico’s history. There was a figurative one, too.

The kick-off would have to be brought forward from 6pm local time (1am Monday BST) to midday, Fifa was told on Friday, and there followed an intense amount of back and forth, so many different people and companies to consider. In the end, it was decided that it would have to remain at 6pm. There was a lot of energy expended for no actual change and on everybody hurtled.

England endured a tumultous buildup to their match in Mexico City, while Trump thanked Fifa publicly for overturning Folarin Balogun of the USA’s red card

Kylian Mbappe has pulled level with Lionel Messi at the top of the Golden Boot charts. Both icons have seven after the Frenchman tucked away the winning penalty against Paraguay.

Erling Haaland (5), Harry Kane (5) and Vinícius Júnior (4) all have the chance to close the gap in the next 24 hours. And also look out for Spain’s Mikel Oyarzabal (4) creeping up on the rails.

В прошлую пятницу я сидела в переговорке и в очередной раз слушала историю про то, как «у нас плохо работают HR». Позиция закрывалась 47 дней. Кандидат в итоге выбрал конкурента, потому что у нас «слишком долго думали». Убыток по расчёту финдира — около двух миллионов. Виноваты, разумеется, мы.

Я в HR двадцать один год. За это время закрыла больше двух тысяч вакансий, обучила четыре команды рекрутёров и пережила три «крупных сокращения», после каждого из которых оставалась в компании. Что, наверное, кое‑что говорит о моей ценности. Но раз в квартал я всё равно сижу в переговорке и слушаю, как я не справляюсь.

Я устала. Не в смысле «завтра уволюсь», а в смысле устала объяснять одно и то же на разных языках разным руководителям. Каждый раз слышу вариации трёх мифов, и каждый раз мне приходится их разбирать. Здесь попробую разобрать их один раз и надолго — так, чтобы можно было потом просто присылать ссылку.

Наверное, пора вновь вынырнуть в ленте хабра с радиолюбительской тематикой и самодеятельным конструированием. В предыдущей паре статей было рассказано про один из шедевров радио‑DIY — специально разработанный для соревнований по КВ‑радиосвязи трансивер RA3AO, а также про восстановление попавшего ко мне в руки экземпляра, которому пришлось практически полностью пересобрать передающую часть.

Дальше нужно было соорудить в пару к нему усилитель мощности примерно на 50–100 Вт для КВ‑диапазонов, желательно со встроенным сетевым питанием и подходящими габаритами, чтобы более гармонично сочетаться с большим настольным трансивером. И вот с позапрошлого лета, с перерывами, шла работа над таким усилителем. Про неё и будет рассказано дальше.

Training document used to teach inspectors updated after campaign by celebrities including Chris Packham

Ofsted, the body responsible for safeguarding in education in England, has dropped guidance for inspectors that linked autism and extremism after an outcry from celebrity campaigners.

An education minister has disclosed that an updated training document “no longer includes reference to children with autism” after claims that it was “offensive” and “clumsy” discrimination.

Darts development organisations and win for David Munyua at PDC World Darts Championship have turbocharged a resurgence in interest in the sport

Peter Wachiuri pumped his fists as he sensed victory at the Jacaranda showground in the Kenyan city of Nakuru. Leading his opponent, James Kamama, in the final of the main event, Wachiuri approached the oche again, picked a dart from his left hand, leaned forward with an intense gaze on the dartboard, and threw double 10.

“Game shot!” the announcer’s voice boomed across the hall. Cheers erupted in the crowd, gospel music played out of the speakers and Wachiuri launched into a celebratory on-stage dance.

Six pieces of suspected space debris found washed up on north Queensland beaches could be “space balls” that are often left over from rocket launches, according to one expert.

The Australian Space Agency confirmed on Sunday it was working to determine the nature and origin of the mysterious objects, which police said were suspected of containing hazardous chemicals.

Я потихоньку пишу книгу для руководителей среднего уровня, публикую в тг, попробую ещё на Хабр порепостить. Вдруг кому-то будет полезно или интересно.

Руководить в среднем звене – это особый мир. Нас всегда тянут в три стороны – подчинённые (ещё вопрос, кто чей подчинённый по факту), начальство (тянут то нас, то наши жилы), и коллеги (или «коллеги», равные по иерархии, зачастую – конкуренты).

Жизнь заставляет нас постоянно балансировать между взаимоисключающими требованиями. Иногда кажется, что своих целей, потребностей, желаний и голоса у нас просто нет – всё навязано кем-то извне. А ты бегаешь, как дурак, и ставишь костыли, чтобы всё это не развалилось, да ещё и как-то работало. В идеале – чтобы развивалось.

Нишу среднего звена я выбрал сознательно. Во-первых, я в ней всегда и работал – общий опыт управления 20 лет. Опыта работы топ-менеджером у меня нет, поэтому о чём не знаю – говорить не буду.

What is the virus? Where did it come from? Are humans at risk? What does it mean for the agricultural sector and wildlife? Experts answer your questions

A deadly strain of bird flu, known as H5 bird flu, has arrived on the Australian mainland.

The federal agriculture minister, Julie Collins, confirmed in late June that a brown skua – found sick in Western Australia – had died from the H5N1 virus. The skua is a wild migratory bird.

Nicholas Stern joins growing number backing Miliband, saying he has vision and experience to revive economy

A former chief economic adviser to the Treasury has called on Andy Burnham to appoint Ed Miliband as chancellor, arguing the energy secretary has a “bold” vision to revive the economy.

Nicholas Stern, a professor at the London School of Economics who was a senior figure in the Treasury during Gordon Brown’s tenure, said only Miliband had the experience and the strategic vision to accelerate investment and rebuild public trust in the state’s ability to “get things done”.

Juggling, trapeze and hula hoop classes for over-50s are taking off as people rediscover their inner child and tap into health benefits

Rumman Talukder’s favourite circus trick is called the Mermaid. Every Sunday, the 60-year-old IT consultant drives from his home in Stanmore to a circus school in Ware to practise it. Hanging from a trapeze by one arm, with his back arched and his legs wrapped around the rope, he says it makes him feel “strong and graceful”.

“My wife thinks I’m mad but in the run-up to turning 60, I decided I wanted to challenge myself; to find things not normally associated with people my age,” he says.

You are dealing with a lot right now. Lean on loved ones, and try not to look too far ahead

My husband recently died. It was a protracted illness, but in the three weeks between him being very ill and him passing I did not get to speak to him about death. We had spoken about it earlier in our relationship and he wasn’t frightened. He was the sort of man who didn’t want a fuss and I never lingered by his bedside; I just did what was needed, had a chat and moved on to running the home. I have cried every day since he died.

I have so many recriminations on my part: feelings of not looking after him, not taking the time … We had planned to move in with my daughter part-time, in another part of the country, splitting our time between her house and ours. Now my husband has died, I will be doing this on my own. My dog, who has been such a companion since I lost my husband, died suddenly. He got me through the past six months. I am not equating the profound loss of my husband to my dog, but I feel overwhelmed with grief.

Cooling down has become political amid record highs, as experts say row is distracting from work of protecting lives

As the afternoon heat rose to a dizzying 41.7C (107F) in eastern Brandenburg on Sunday, taking German temperatures to unprecedented highs, Mario, 65, took precautions but did not panic. Two years ago, a fierce heatwave had prompted him to buy a powerful device that few Germans own: an air conditioning unit.

“The summers are slowly getting warmer,” says the retired handyman in Neuzelle on the German-Polish border, whose bungalow is now among the 6% of German homes with fixed air-conditioning. “And as you get older, the heat gets harder to endure.”

Farage is under pressure over £5m gift, byelection losses and rise of rival Restore but allies say exit speculation is ‘wishful thinking’

“Of course he’s tired. He’s just done two months campaigning every day on the road, it would be weird if he wasn’t. But that doesn’t mean he’s going to quit,” says one friend of Nigel Farage who has spent time with him in recent weeks.

Westminster has been ablaze with rumours that Farage is growing weary in the job of leading Reform UK after the bruising scandal around his decision to accept a £5m gift from the crypto billionaire Christopher Harborne. He is now also facing further questions about whether his lifestyle has been partly funded by George Cottrell, his close friend and a convicted fraudster.

Anthony Albanese mocks ructions on conservative side of politics and says three rightwing parties are caught up in ‘race to the bottom’

Liberal frontbencher Dan Tehan says he does not want to be in a rightwing coalition with One Nation, despite senior colleagues urging closer ties with Pauline Hanson and polls suggesting her rise will make it difficult for the opposition party to ever govern in its own right again.

The prime minister, Anthony Albanese, on Sunday mocked the Liberal, National and One Nation parties as an “axis of grievance” on the conservative side of politics, but Tehan said a formal alliance was not being discussed among his colleagues.

In a political wasteland dominated by billionaires, war criminals and mega-corporations, the head of the Catholic church is a rare figure of moral leadership

What do Donald Trump, Vladimir Putin and Benjamin Netanyahu have in common? Answer: a chronic inability to tell right from wrong. The three leaders currently causing the most harm in the world share a predilection for violence, a chilling lack of compassion, and extraordinary self-regard mixed with paranoia. Yet the characteristic linking them most closely is their rejection of – or failure to grasp – basic moral standards. Worse, these men typically behave, in their public lives at least, in ways that are fundamentally immoral. And that’s a problem for everyone. Their moral malaise is contagious.

Ideas about what, in absolute terms, constitutes right and wrong are always contentious, as moral philosophers from Aristotle to Kant have shown. Pope Leo, leader of the world’s Catholics, warned recently that “we are living in a time when it is becoming difficult even to recognise what is truly good for everyone”. Yet most people, most of the time, observe a personal moral code held in common with others. There is broad agreement, for example, that it’s wrong to kill, steal, cheat and lie. In an ostensibly secular age, 76% of people worldwide identified with a religion in 2020 – a potent expression of individual and collective morality.
