Это вторая статья из цикла статей о создании компактной кросс‑платформенной библиотеки для разработки приложений с графическим интерфейсом на языке C++ — Frenchie. Для тех, кто привык изучать исходный код самостоятельно, репозиторий с исходным кодом библиотеки находится по ссылке. В данном материале я расскажу, про ту часть библиотеки, которая управляет состоянием контекстного окна и отслеживает связанные с ним события - platform backend.

Цель всего цикла материалов — дать представление о том, как устроены подобные проекты, начиная от открытия контекстного окна и управления его состоянием, заканчивая рисованием графических примитивов. Надеюсь, что весь цикл материалов окажется полезным как для тех, кто начинает свой путь в разработке приложений с графическим интерфейсом, так и для опытных разработчиков.

Anthony Albanese probably didn’t expect an interview with a comedian in her “Bush Barbie” character would have kickstarted the biggest firestorm of the week.

But the prime minister, appearing alongside a stuffed copy of his beloved cavoodle Toto – fell victim to an entirely avoidable and regrettable controversy when he played along with a “shag, marry, date” game.

MCP упростил жизнь разработчикам: теперь у AI-агентов есть единый способ подключаться к инструментам и сервисам.

Но у этой стандартизации есть обратная сторона — каждый MCP-сервер становится новой точкой доверия и потенциальной атакующей поверхностью.

В статье разбираю:

-почему у LLM нет чёткой границы между данными и инструкциями -как tool poisoning, indirect prompt injection и sampling abuse работают на уровне MCP -почему даже “безобидные” документы и описания инструментов могут приводить к выполнению команд -какие реальные атаки уже зафиксированы в экосистеме MCP

как индустрия пытается закрыть это через gateways, sandboxing и OAuth-архитектуры

Также показываю практическую проверку на уязвимом MCP-стенде и результаты детекции вызовов инструментов на своем сканере BarkingDog.

US telecom giant Comcast to snap up free-to-air TV channels and streaming platform to create UK’s biggest commercial broadcaster

Sky has announced a long awaited £1.6bn deal to buy ITV’s broadcasting and streaming arm to create the UK’s biggest commercial broadcaster.

Sky, which is owned by the US telecoms company Comcast, will pay £1.2bn in cash initially for ITV’s media and entertainment business, which include its free-to-air TV channels in the UK and ITVX streaming platform. It has agreed to pay a further potential £200m in the second half of 2028, depending on 2027 advertising revenues.

Launch comes just hours after Australia and Fiji sign defence agreement as expert says timing not a coincidence

China has conducted a long-range missile test in the South Pacific just hours after Australia signed a defence agreement with Fiji, sparking condemnation from Canberra and regional leaders.

The Australian foreign minister, Penny Wong, said the missile test was “destabilising” to the region, while her New Zealand counterpart, Winston Peters, described it as “deeply concerning”.

Broadway star, who is performing on the vessel, expresses shock after authorities ban Scarlet Lady from docking in Kuşadası

A cruise ship carrying 2,000 LGBTQ+ passengers and the Broadway performer Patti LuPone has been blocked from entering Turkey after local authorities said their behaviour didn’t “align with the structure of our society and our moral values”.

Virgin Voyages’ Scarlet Lady set sail from Athens, Greece, on 5 July for what was billed as “an epic all-gay voyage” over 10 days run by Atlantis, a US company that puts on cruises and vacations for LGBTQ+ people.

Crowds swelled through Tehran as mourners dressed in black carried flags proclaiming: ‘We will rise’

A crowd of “millions” assembled on Monday for the funeral procession of Iran’s assassinated supreme leader, Ali Khamenei.

The scale and depth of the march, however engineered, represents an extraordinary turnaround for a country that only seven months ago was gripped by street protests at which thousands of people were killed by government security forces.

Exclusive: National Housing Federation says ending quotas for developers could cost 32,000 homes over 10 years

Half of all affordable housing supply in rural England could be under threat under plans being considered by ministers to relax regulations for private housing developers, according to analysis.

The government has proposed ending affordable housing quotas – known as section 106 agreements – for new developments of between 10 and 49 houses in an effort to jumpstart sluggish housebuilding rates. Ministers are due to make a final decision within weeks on whether developers should be allowed to make cash payments to local authorities instead.

‘Over-enforcement poses significant risk to the communities that we try to protect,’ royal commission told

A decision aimed at reducing “censorship” on major social media sites including Facebook and Instagram potentially led to greater levels of hate speech, the royal commission into antisemitism has heard.

Meta announced in January 2025, after the re-election of Donald Trump in the US, that it would “reduce censorship”, get rid of factcheckers and only tackle illegal and very serious violations proactively, relying on users to report less serious breaches. Its platforms include Facebook, Instagram and Threads.

Принято считать, что люди сотни лет назад были глупыми, темными и до смерти суеверными. Отчасти это, конечно, правда. Но в своей изобретательной находчивости они довольно часто превосходят человека нынешнего. И данное “волшебное” устройство лишний раз доказывает, что умственные способности людей старины недооценивать нельзя ни в коем случае.

President Donald Trump is heading to Ankara, Turkey, for the annual NATO summit. Last year, he pushed NATO allies to spend more on defense. This year, his mission is to try to enforce those pledges.

Norah Jones hosts the legendary rock stars as they return to the studio for a new album. Plus, mindfulness meditation with the Getty Museum

This official Rolling Stones podcast is hosted by Norah Jones and released across six weeks, with each chapter charting the making of the band’s upcoming studio album, Foreign Tongues. Unsurprisingly, it’s a polished exercise in PR for one of the world’s biggest acts. Its first episode is also something of a tribute, as it considers how Mick, Keith and Ronnie returned to the studio following the death of drummer Charlie Watt in 2021. Hannah J Davies

Documentary intersperses pastel scenes of spotless tourist resorts with candid interviews with the asylum seekers who labour to keep them pristine

Every year, millions of tourists flock to the Canary Islands, a Spanish archipelago in the Atlantic Ocean where the sun always shines. Through static shots resembling picture postcards, Mette Carla Albrechtsen’s pastel-hued documentary captures the leisure activities on offer: cerulean rooftop pools, pristine sandy beaches and raves that stretch into dawn. But as the resort asks its visitors to put their minds on hold, the film casts a critical gaze on the human labour that powers this luxury paradise. Interspersed with restful scenes of relaxation are candid interviews with on-site workers, whose stories reveal the trials and tribunals behind the glossy travel brochures.

Some simply come to the Canary Islands looking for an escape from routine. One long-time Danish resident laments the gloomy weather of his home country, but he finds it difficult to develop lasting relationships in the archipelago, a transitional space where few of his migrant friends set permanent roots. Others flee from more desperate circumstances – economic hardship and war. In one staggering juxtaposition, the film cuts from a popular nightclub to a sombre dock where social workers tend to a group of migrants rescued from dangerous sea journeys. Promised a safe passage to Spain by their traffickers, tens of thousands of asylum seekers are now left in a stateless limbo, all while contributing their labour to the various luxury resorts.

Premium Bluetooth noise-cancelling cans combine comfort with extensive connectivity and a user-replaceable battery

Sennheiser’s latest Momentum Bluetooth headphones build on the German audio specialist’s renowned sound quality with improved noise cancelling, exceptional comfort and a user-replaceable battery to keep pace with rivals.

The Momentum 5s cost £330 (€400/$400/A$749) and directly replace their three-year-old predecessors, facing strong competition from Bose, Sony and Sonos.

Sedaris plays up the curmudgeonliness in a collection that nevertheless entertains

I’ll confess my heart sank slightly at the prospect of reading David Sedaris’s new volume of essays, some of them previously published in the New Yorker, and which, relative to his earlier output, strike me as increasingly shticky and reliant on anecdotes too thin for their weight. (From the essay Little America: “Few things drive me crazier than people who put their feet up on the furniture.”) After nine previous volumes, Sedaris would seem to be suffering from a problem that comes to all writers in the end, and memoir writers in particular, which is a dearth of useable material. What can there possibly be left in the Sedaris backstory that the writer hasn’t already mined?

Well, as it turns out, there is still lots of useable stuff, as well as some an editor could have put a red line through, although Sedaris, who has sold more than 16m books, may well consider himself part of the post-editing elite. (I was reminded while reading of a line from a profile of JK Rowling several years ago in which, referring to The Casual Vacancy, Ian Parker wrote: “Some sentences cause you to picture a Little, Brown editor starting to dial Rowling’s number, then slowly putting down the handset.”) And perhaps it doesn’t matter; as long as Sedaris’s superfans keep coming, both for the books and events, why mess with the formula? For less committed followers, however, reading Sedaris is a glitchier experience than it was.

The island has a culinary tradition as old as its ancient olive trees. Our writer savours its family-run tavernas, village bakeries and local produce

As someone with Cypriot roots and distant Greek heritage, I’m often asked the question: which is the best island? People lean in, expecting a secret – some tiny, untouched haven, known only to locals. My answer is always the same: Crete. With its fiercely proud identity, warm communities and exceptional food, it feels both deeply Greek and entirely itself.

For our anniversary weekend, my husband and I head to Lassithi, in the island’s far eastern corner. As a chef and food writer, I’m drawn to the area’s reputation for exceptional produce: Sitia extra virgin olive oil, creamy xigalo cheese, mountain honey and an abundance of excellent tavernas.

• Coach calls it ‘greatest day’ in country’s football history

• Neymar appears to announce Brazil retirement

Ståle Solbakken called it “the greatest day in Norwegian football history” while Erling Haaland labelled it one of “the sickest”. One thing is for certain, however: Norway are through to the quarter-finals of the World Cup for the first time after deservedly beating Brazil.

A late double from Haaland decided the contest, with the final score 2-1, and immediately caused chaos back home. Tens of thousands took to the streets of Oslo in the early hours to celebrate, including an impromptu gathering at the royal palace, where fans were greeted by Crown Prince ‌Haakon, who was wearing a Norway scarf.

• Unused substitute fell over advertising board

• Midfielder given oxygen and taken to hospital

A historic night for England as they beat Mexico 3-2 in their World Cup last-16 tie was soured by an injury sustained by Jordan Henderson after falling over an advertising board in the post-match celebrations.

The former Liverpool captain, who was an unused substitute, was taken to hospital and it was confirmed later that he had broken his wrist and that he is out of the tournament.

Organisation says objects consistent with ‘debris from a foreign rocket body that recently re-entered the atmosphere’

The Australian Space Agency has said the six so-called “space balls” found in north Queensland were likely from a “foreign rocket body” that had recently re-entered the atmosphere after being in orbit.

The six mysterious objects were found by the public washed ashore in the Forrest Beach area, north of Townsville, on Friday, Saturday and Sunday and were suspected of containing hazardous chemicals.

From the World Cup fan park in Manchester, supporters cheer through the night as England beat Mexico to advance to the quarter-finals

Manchester is up there with the greatest footballing cities in the world. But even here, the fans had hardly seen a game like it.

In the early hours of Monday morning, at Europe’s biggest World Cup fan park, as the final whistle blew after an agonising 11 minutes of injury time, the crowd cheered with a roar loud enough to wake anyone in Manchester still asleep.

The distinct spices of their respective regions make these approaches to runner beans uniquely different, but equally flavourful

I always look forward to runner bean season, and especially to cooking them in stir-fries with Indian spices. Today’s recipes are very different from each other, not least because they hail from two very different regions, namely Rajasthan and Kerala, respectively, both of which have their own distinct spices and flavours.

The firm’s share price has risen 80% under Allison Kirkby’s leadership – but pressure remains for her to deliver further growth

• Business live – latest updates

If timing is everything, then Allison Kirkby may have judged it perfectly.

Since becoming BT’s first female chief executive more than two years ago the company’s share price has climbed 80%, an investor-pleasing turnaround that has seen Kirkby well-rewarded with a pay and bonus package of £5.6m last year, the largest for a boss of the telecoms company in well over a decade. However, there are questions over how much credit Kirkby can take for the apparent revival of the business.

The men, who drugged and secretly filmed their victims, were members of an online gang targeting mainly women of Chinese heritage

Early last year, Ivy*, a Chinese student living in Germany, got a phone call from the police. At first, she thought it was a scam. An officer said they needed her help with an investigation involving someone she once knew. What followed turned her world upside down.

The police told her that her former boyfriend, identified in court documents as Tong Z, had been investigated for sexual assault and covert photography. Then came the tougher blow: police showed her a number of nude photos Tong Z had secretly taken of her while she was asleep. Ivy, now 27, recognised herself, though she had no memory of the moment.

Playing at altitude with the passionate backing of 80,824 fans at Estadio Azteca, and with a man advantage for most of the second half, Mexico scored twice but could never equalize and lost 3-2.

⚽️ Mexico 2-3 England | Player guide | And email us

We haven’t even mentioned Balogun-gate yet. The Belgian FA, and you can assume a large proportion of the football world, has been left “astonished” by Fifa’s decision after lobbying by Donald Trump to reverse the suspension given to the striker for his red card in the team’s win over Bosnia and Herzegovina. He is now free to play in the last-16 game against Belgium.

Sources have told the Guardian that Trump made three calls to Fifa, starting from Wednesday, to ensure that the change was made.

Клиент - производитель строительных материалов.

Каждый день на погрузку стройматериалов приезжают десятки фур. При этом, габариты паллет, на которых грузят материалы, фиксированы жестко, а вот реальные размеры машин — нет. Внешне кузов может выглядеть ровным прямоугольником, а внутри могут быть скрыты «сюрпризы»: заниженная к кабине крыша, выгнутые борта или самодельные крючки на дверных стойках. Глазом эту кривизну не оценить. 

В момент погрузки, вилочный погрузчик заносит паллету шириной 2,40 метра, а она упирается в “неучтенный” выступ внутри кузова. Цена такой ошибки — повреждённый груз, развёрнутая на КПП машина, простой ворот, сорванный график отгрузки. 

Решение заказчика: поставить человека на осмотр: сотрудник заглядывает в кузов и по визуальному осмотру решает, грузить фуру или разворачивать. Это медленно, субъективно, не масштабируется, а отказы по геометрии кузова составляют заметную долю разворотов.

Задача, которую решала наша команда: автоматизировать осмотр кузова перед погрузкой. Убрать сотрудника из точки принятия решения и выдавать решение “грузить / не грузить” на основании математических расчетов и реальной геометрии.

Планка задана высокая. Нужно замерять сразу три габарита:
