Прекратите это делать! Начните делать другое! Я говорю о двух типах ценности — одна тает от массовости, другая ею живёт.

Есть приёмы, которые работают, только пока о них знают немногие. Рабочий способ обхода блокировки, удачная торговая стратегия, налоговая лазейка, лайфхак против корпоративной политики паролей — все они могут терять силу, как только становятся известны всем. А есть противоположный класс вещей: пока ими пользуются мало людей, толку от них почти нет, а ценность растёт как раз с ростом числа участников.

Дальше в статье — что это за механизмы, кто их впервые описал и какие практические выводы отсюда следуют.

• Uefa says claims will be made in Switzerland

• It says claims relate to alleged criminal mismanagement

Uefa is preparing to make a criminal complaint against Gianni Infantino for alleged “criminal mismanagement” in connection with his failed Fifa Forward Enterprise plan and has applied for the release of documents related to its conception.

In an explosive escalation of the war engulfing football’s governing bodies, Uefa has made separate applications in the United States for information, including from Fifa and the investment firm Thrive Capital.

Обычная логика такая: не хочу, чтобы меня узнавали — открываю приватное окно, и всё, я новый посетитель. Логика была верной примерно до середины десятых годов.

Сейчас узнавание держится не на cookie, а на наборе свойств самого браузера. Их не надо никуда сохранять — они просто есть, и по их сочетанию посетитель определяется с высокой надёжностью. Очистка хранилища на это не влияет никак: удалять там нечего.

Experts say findings mean breast screenings for cancer could also flag cardiovascular problems in women

Doctors have discovered a way to use routine mammograms that screen for breast cancer to spot heart disease, the world’s leading – and frequently underdiagnosed – cause of death in women.

Researchers analysed the scans using artificial intelligence and were able to successfully identify women with coronary heart disease, high blood pressure or who had suffered a stroke.

• Wrexham third strip unveiled with similar badge to O’s

• ‘What you playing at?’, Orient post to Hollywood owners

Leyton Orient have criticised Wrexham’s owners, Ryan Reynolds and Rob Mac, for putting a badge on their new kit that mirrors their own.

Wrexham unveiled their new third strip on Wednesday; it has cream with a black collar and terracotta-orange detailing, and it received the Hollywood seal of approval with pictures of Mac and Reynolds modelling it on the club website.

A welcome return to watch Cambridge brought back a whole lot of memories, nostalgia and contemplation

On 11 February 1989, Cambridge United beat Hartlepool 6-0. My memories of the game are faint. The internet can’t even tell me who scored – perhaps Laurie Ryan got a couple. I do recall walking past some Hartlepool fans on Coldham’s Common who were peering into a brook. “Looking for a new centre forward?”

Not a terrible joke from my dad. There was polite laughter at least.

I was thrilled to finally experience the Nevada festival. But I underestimated how hardcore it was – and the life lessons it would bring

I was naked in our tent at Burning Man last year when all hell broke loose. The 100km/h (62mph) gust wrenched our tent stakes from the ground – and me from my nap.

I threw on a dress, fear coiling in my belly when I saw the midafternoon sky had turned dark.

Градиентный спуск — стандартный инструмент обучения нейросетей. Но с точки зрения линейной алгебры операция обновления весов выглядит некорректно: мы складываем вектор и ковектор.

Paul Greengrass drama The Uprising was supposed to be a historical epic about the Peasants’ Revolt of 1381 – but a strange new campaign has inserted a surprising figure

Nobody likes to have the full plot of a movie spoiled before they’ve even seen it. However, sometimes this can be taken to the extreme. Take the new Paul Greengrass movie, The Uprising, for example. It is two weeks away from its US release and not only does nobody know the plot, but nobody seems to know what it is even about. Seriously, nobody at all. The film’s distributors just spent yesterday squabbling in public about whether Robin Hood was in it or not.

Here’s what we know so far. Initially, all the trailers and promotional materials made The Uprising look like a film about the Peasants’ Revolt that tore through England in 1381. And this was very exciting, since the revolt was a thrilling moment in history that has been bizarrely underserved by Hollywood over the years. Most exciting of all, though, it sounded like it fit exactly into Greengrass’s wheelhouse: full of action and realism and political awareness.

Bag, camera and pipe belonging to 86-year-old are latest relics uncovered as glaciers melt due to global heating

An 86-year-old mountaineer has been reunited with his backpack and climbing equipment after the kit emerged from a melting glacier in Austria – more than 60 years after he was forced to leave them there.

Items including an ice axe, camera and a pipe dating from the 1950s or 1960s were discovered on the Sulztalferner glacier in Austria’s Tyrol region, at an altitude of 2,955 metres (9,700ft) above sea level, by a hiker in July.
