At 3.30am, Vello Senkel awoke to a knock on his door. Standing on his doorstep were his neighbours with an urgent request: “Do you have salt? We want to boil macaroni.” He acquiesced, but it turned out that salt wasn’t the only ingredient they were missing: “And do you also have macaroni?” His warm face, framed by jaw-length white hair, is at once charmed and outraged as he recounts the interaction while smoking a cigarette outside his apartment building the following morning.
Senkel, whose nickname is Velho (Finnish for wizard), is known for his proficiency in the kitchen. In his apartment, where he lives alongside 77 other formerly homeless people in a Helsinki suburb, he shows me his fully stocked freezer. From his neatly organised fridge he pulls out the jars of pickled cabbage and shrimp salad he has prepared to take to a friend’s house for lunch later.

A series of moves by Donald Trump’s administration to sow doubt in the integrity of US elections has intensified concern among voting experts – and sparked hope among election deniers – that it could declare a national emergency.
The White House and US federal agencies have released a string of documents this summer – including disputed analyses of alleged voting by noncitzens and historical intelligence memos – stoking expectations that the US president could move to exert greater control over November’s US midterm elections.

The contest in Nevada's 2nd Congressional District should be a shoo-in for Republicans. But a problematic candidate, inflation and Trump's unpopularity give Democrats not far-fetched hopes for a massive upset.

Two years ago, Zainab Bibi Ahmed thought she had turned her back on the Democrats for good. Now, she is volunteering for the party’s US Senate nominee in Michigan, Abdul El-Sayed.
Ahmed was one of 100,000 people to vote uncommitted in the February 2024 Democratic Michigan primary, in a bid to send a message to then US president Joe Biden about his support for Israel, as people watched what Amnesty International later called a “live-streamed genocide” in Gaza on their screens.

Today, if you wish, you can go get a staggering amount of granular data about your health without your doctor’s involvement. All on your own, you can get an MRI of your entire body, a CT of your coronary calcium, an ultrasound of your blood vessels, and maybe someday an immersion ultrasound in a spa.
Direct-to-consumer medical imaging tests are a huge and growing business worth billions of dollars. Over 100,000 Americans are already customers. But do these test results actually make us healthier?
As a radiologist, a doctor specialized in the alchemy of turning information into health, I translate data hidden in images into words that motivate behavior to promote healthier, longer lives. Because it is central to what we do, radiologists have grappled for decades with the question of whether and how information improves health. It turns out to be surprisingly complicated.
In order to make a difference in someone’s health, the test must accurately predict or diagnose a condition, resulting in a change in mindset and behavior, and that change in mindset and behavior must produce a better outcome than not doing the test.
For example, whole-body MRI of the general public, a test not recommended by any medical guideline, medical society, or payer, creates information by taking a picture of your body. That information is accurate for some diseases but not others. It might change your mind by finding something you didn’t know about, like a small mass in your kidney or thyroid gland, which then might change what you or your doctor does. For example, your doctor might order another test to better understand if the mass is important or perform surgery to take it out.
This seems logical. But the reason whole-body MRI of the general public isn’t recommended while other screening tests are is because in the absence of evidence, it is believed to be unlikely to produce a better outcome than doing nothing at all.
Many people think, as I once did, that early diagnosis always improves health. That logic is especially intuitive for an early diagnosis of cancer. But in many cases, that intuition, however understandable, can be wrong. Finding something with a diagnostic test might not help, despite creating an illusion that it does.
For both examples I gave—small thyroid masses, small kidney masses—it has been well documented that aggressive efforts to treat them, despite many being cancer, does not help most people. Isn’t that strange? Yet despite ourselves, we keep finding and removing them.
That’s the tricky thing with diagnostic tests. It’s terrifically hard to unsee something. For those who receive no benefit from treatment, only secondary harm results: surgical pain and complications, the anxiety of a scary diagnosis, and financial burden.
There are numerous non-intuitive examples like this in which only in retrospect do we realize patients have been harmed because a diagnostic test and its downstream actions were promoted to millions before confirming things worked as intended. This is why scientists and medical professionals are so obsessive about evidence and statistics. It’s really hard to know if something is hurting or helping if we rely on common sense.
The likelihood of benefit and the likelihood of harm matter tremendously. For example, if whole-body MRI is performed on a high-risk patient with a cancer-causing genetic syndrome, it is much more likely to create health benefits than if it were to be performed in the general population. This is one of the paradoxical things about diagnostic tests. It’s not just about test accuracy. Equally important is the people being tested, because baseline risk strongly influences the benefits.
Harm is often caused not by the test itself, but from actions taken to manage the information of unknown significance it produces. It is in this way that a seemingly harmless test can hurt people. We do tests to find things, and when we find things, we commonly act, even when we shouldn’t, because we aren’t rational decision-makers.
Direct-to-consumer testing will change how medicine is practiced. It empowers us to make personal decisions about our health and generates novel, complex information that will unlock scientific breakthroughs.
When buying one of these tests, we should pay attention to what the company is claiming. Is their test a curiosity, an entertainment product, a research tool, or clinical care? The lines are often intentionally blurry.
The need for scientific support, informed disclosure, and regulatory compliance increases as the test moves from curiosity toward clinical care. If the test has only been shown to provide information or to make a diagnosis, or has only been shown to improve health in patients with specific risk factors different from our own, we should be skeptical. As they say, buyer beware.
Many companies encourage us to assume their test improves our health. In such cases, the information we are buying may help us, hurt us, or be a placebo and do nothing at all.
Допустим, вы решили заняться беспилотными технологиями в стартапе или RnD подразделении при университете. У вас за плечами мобильный робот на условном Arduino. И вот появился заказчик, который хочет автоматизировать свои процессы и даже готов за это заплатить. Вам нужно взять некую технику, обвешать датчиками и приводами, добавить вычислитель и научить автономно двигаться, попутно решая проблему заказчика. У вас всё серьёзно: у проекта есть руководитель, электроникой занимаются электронщики, механикой - конструктора, есть специализация у программистов (системы восприятия, навигации, планирования и т.п.). Казалось бы, что может пойти не так?
Ниже я хотел бы описать ряд проблем, с которыми столкнулся (как программист) при работе над проектами по созданию беспилотных технологий. Врядли я кого-то удивлю, наверняка это всё “детские болезни”, которые решаются правильным планированием и в зрелых компаниях не встречаются. Но на начальном этапе о них полезно помнить.

Сразу два важных предупреждения:
Первое: сначала будет немного теоретической нудятины, но оно того стоит.
Второе: уважаемые химики, это научно-популярный текст, я упрощаю. Если захотите в меня что-то бросить, кидайте в меня донатами.
Поехали.
Что вообще нужно для пожара?
Один скажет: нарушение техники пожарной безопасности.
Другой: источник огня
Третий: наличие воздуха

Hackers linked to Iran have been blamed for a cyber-attack that caused a British power plant to be temporarily shut down.
The incident involved a small-scale energy generator, according to the UK government, which said that at no point was there a risk to the wider energy system.

At Tata Steel’s factory in Llanwern, south Wales, production lines that should be running full-time are now falling quiet for parts of the day, with workers being put on to maintenance and cleaning work while machines sit idle.
There aren’t enough orders to keep them running all the time, the company says, because of a surge of cheap steel coming from Asian countries that is threatening the viability of several UK sites that make similar products, and risk hundreds of jobs.

Scottish people have always been known for their friendliness. “We’re not like the south of us,” they say, referring to England. The official slogan of Scotland’s largest city, “People make Glasgow”, appears everywhere – on T-shirts, buildings, bus stops and mugs. And when I first moved to Scotland from India in 2018, I was immediately welcomed by kind strangers and helpful neighbours. People showed curiosity, rather than intrusiveness. They respected queues; told me I fit right in. Music, art and cultural events were considered inclusive spaces in the city, with calls for diversity, creativity, inclusion – all the good things.
As an outsider, this was a dream come true: to be myself, to be alone, to have brotherhood and a community. It was life-changing. I could do whatever I wanted, wear whatever I wanted, walk by myself at night, even. That is a luxury, especially for a woman. But something has changed, particularly after Covid, a global recession and years of austerity. Now, I watch the steady rise of far-right, fringe violence and I feel a special scrutiny upon me.

It is a sticky, sweltering July afternoon, and I have accidentally found myself at a wake with Jorja Smith. I’m told that the pub where we have met, in the leafiest part of leafy south-west London, is usually a safe bet for an inconspicuous table. But today, sweaty black suits carrying pints drift between tables, and long queues snake round the bar.
Dressed in a simple tank top, bare-faced with her hair scraped back, Smith is waiting for me when I arrive. “I’ve been waiting for my drink for ages,” she says. “But I feel bad saying anything because, you know …”

Очередная история про AI и разработку, но с конкретикой. Mattermost на Team Edition, три ежедневные боли: нельзя нормально ответить на сообщение в канале, не видно прочитал ли коллега, для созвона кидаешь ссылку на локальный Jitsi с отдельной авторизацией.
За день собрал три плагина в Cursor: reply с цитатой, галочки доставлено/прочитано, голосовые комнаты на Pion прямо в server-плагине. Личная инициатива, не тикет в бэклог. Коллегам понравилось, мне в копилку.
Рассказываю, почему не переезжали на другой мессенджер, как задавал рамки AI (опыт с медиа помог), и где плагины не работают: спойлер, нативные приложения.
P.S. про обложку. Превью для Habr тоже сгенерировал AI. Оно, конечно, вообще не похоже на настоящий Mattermost: другие цвета, другой UI, будто мессенджер из параллельной вселенной. Но мне так понравилось, что решил оставить. Пусть будет из разряда «ожидание vs реальность» или «Mattermost, который мы заслуживаем».
