В прошлый раз я писал про потерянное пробуждение и получил в комментариях справедливое замечание, что примитив там классический. Так и есть. Сегодня про место, где классики меньше: как в моём ядре устроено переключение контекста, и почему ассемблер там знает смещение поля в структуре Rust.

Это неприятная связь. Ассемблеру нужен байтовый доступ к сохранённым регистрам, а раскладку структуры определяет компилятор. Если эти двое разойдутся во мнениях, вы не получите ошибку компиляции. Вы получите ядро, которое пишет регистры мимо и падает где-то далеко от места ошибки.

Taxi driver says he acted as middleman between Yorgen Fenech and three men already convicted of €150,000 contract killing

The businessman accused of paying for hitmen to murder the journalist Daphne Caruana Galizia was impatient for the killing to take place, and once texted from his boat to say he was “preparing champagne” to celebrate, a jury in Malta has heard.

Yorgen Fenech, the 44-year-old heir to a property empire that includes several Hilton hotels, is on trial in Malta for complicity in the murder of Caruana Galizia. She died in a car bombing in October 2017 after publishing a series of revelations about senior politicians that were so damaging they triggered a snap general election.

The 21-year-old British boxer has the chance to become the second youngest world heavyweight champion after Mike Tyson when he fights for the IBF crown this month

Moses Itauma was initially unmoved when hearing that his bout against Filip Hrgovic in London on 29 August had been upgraded to a fight for the vacant IBF world heavyweight title.

“I didn’t really have any reaction,” Itauma said on Friday afternoon. “I was like, if I’m fighting Hrgovic and I’ve got the opportunity for it to be a world title, then yeah, chuck it on the line. I didn’t have any other feeling. I was taking Hrgovic serious – and, now the fight is for a world title, I’m still taking him serious. It’s still the same fight, innit?”

Serious failings by one academic, and his bosses at the University of Cambridge, should not be allowed to undermine wider progressive goals

Jason Arday’s resignation from the University of Cambridge on Wednesday marked a full stop of sorts, but not an end to the furore surrounding his promotion to a professorship at the age of 37. Academic colleagues have demanded, with justification, that an investigation into his appointment to the faculty of education in 2023, and the subsequent fallout, should include people from outside the university. Allegations of plagiarism and claims made by Mr Arday about his background, career and charity fundraising remain under scrutiny. The memoir for which he said he had received a huge advance, billed as a triumph over adversity including an early autism diagnosis, is scheduled to appear later this month. His publisher, Simon & Schuster, ought to pause while inquiries run their course.

But several things are already clear. By failing to do due diligence on Mr Arday before launching him, with fanfare, as Cambridge’s youngest-ever black professor, and through its inadequate response to later challenges, the university has done a serious disservice to black and neurodivergent scholars more widely. It has also set back the efforts of all the people and groups who have worked in good faith, over many years, to boost the presence of underrepresented groups in influential positions.

The Fifa president’s attempt to brazen out the storm, after attempting to sell a stake in the World Cup to private equity, adds insult to injury

“How did you go bankrupt?” a character is asked in Ernest Hemingway’s novel The Sun Also Rises. “Gradually, then suddenly” comes the reply. Right now, Fifa’s justly besieged president, Gianni Infantino, is experiencing something similar in relation to the loss  of his own authority.

Since taking over the running of world football’s governing body in 2016, Mr Infantino has survived regular criticism of a monetising approach which has often come at a sporting cost. But since egregious plans to sell a stake in the World Cup to the brother of Donald Trump’s son-in-law were leaked to the media, his credibility has been draining away at speed.

Hiring a convicted antisemite as an adviser; rabble rousing at a time of violent unrest. She is still in a race to the bottom and making too many mistakes

The Keminaissance will be delayed. For nearly a year, Conservative optimists and a clutch of supportive pundits have been forecasting an upturn in the fortunes of Kemi Badenoch, confident that her party will emerge from the crater it fell into in 2024, overtake Reform UK to become once again the main party of the right and, who knows, maybe, with a following wind, even push Labour aside and return to government. Every sign of strength from the Tory leader – a robust conference speech here, a viral clip on social media there – has been hailed as evidence of the coming Keminaissance. On the evidence of the past week or so, we will have to wait a little longer.

It’s quite true that Badenoch’s personal ratings are better than those of her party. True, too, that she ended a long losing streak when the Tories won a Westminster seat at the Aberdeen South byelection in June. But there is a more recent election result that should temper the boosters’ enthusiasm, along with a series of decisions that confirm that, when it comes to both strategy and judgment, Badenoch is badly lacking.

Group calls for ‘thorough and transparent investigation’ of hiring of professor who resigned after his claims came under scrutiny

The University of Cambridge has announced a review into the way it vets and hires senior academic staff in an effort to fend off external and internal criticism of its appointment of Jason Arday as a professor.

But a group of Cambridge academics quickly rejected the university’s response, saying: “We strongly believe that a thorough and transparent investigation into the wider circumstances of this damaging episode is essential.”

Excel-таблицы, интуиция опытного диспетчера и авральные совещания по пятницам. Знакомая картина для любого производственного предприятия? Вопрос о переходе к автономному планированию сегодня звучит уже не как «когда-нибудь», а как «сколько можно ждать».

Давайте разберёмся, где мы находимся на этом пути — от ручного управления к заводу, который планирует сам.

Человек или машина: разрушаем мифы

В массовом сознании «автономное планирование» — это чёрный ящик: на входе заказ клиента, на выходе — идеальный график работы станков без участия человека. В реальности всё прозаичнее и сложнее.

Современные системы планирования — это не замена специалиста, а его усиление. Искусственный интеллект здесь выступает в роли сверхмощного аналитика, способного переварить терабайты данных за секунды.

Концепция «цифровой панели планирования», предложенная немецкими исследователями из Института Фраунгофера, отлично иллюстрирует этот подход. Алгоритм мгновенно проверяет тысячи скрытых ограничений (готовность оборудования, наличие сырья, квалификацию персонала) и предлагает оператору несколько оптимальных вариантов графика. Но финальное решение и ответственность всегда остаются за человеком. Это принципиально важный момент, который снимает главную фобию индустрии — страх перед полной заменой людей машинами.

Мы жили с этой мыслью полтора месяца: подписчики шли, цена держалась, отчёт выглядел терпимо.

Пока не посчитали, сколько людей застрявает между «интересно» и «подпишусь».

Конверсия перехода в подписку ниже десяти процентов означала, что мы просим у человека лишнее действие.

Рассказываю, как мы поменяли маршрут на сайт, почему две почти одинаковые цены за действие значат разное и почему скидка не чинит лишнюю ступеньку в воронке.

Всю свою сознательную жизнь я «учил» немецкий: в школе, универе, на внутренних курсах IT-компании и самостоятельно. Слово «учил» я поставил в кавычки, потому что на самом деле я ничего никогда нигде не учил, ну разве что зазубрил немецкий алфавит в школе. Всё как-то училось само, слова запоминались после нескольких повторений, грамматика – после нескольких упражнений. Слава Богу, память всегда была хорошая. Но во-первых, если в будущем эти слова и грамматика не использовались, всё это вскорости выветривалось из головы, а во-вторых, так это не работает со сложными темами. Такими, как, например, склонение немецких прилагательных.

Тем, кто учит английский, повезло: прилагательные там не склоняются вовсе, но в немецком (как и в русском) всё совсем не так:
