«Освоить профессию с нуля» — популярный запрос, но не всегда корректный. А что, если абсолютного нуля не бывает? Ведь у каждого из нас есть свой опыт, знания и преимущества в чём-то своём.

Хабр, привет! Меня зовут Альберт Болотнов, я главный системный аналитик продукта в бигтех-компании. Я отучился на инженера в МГТУ им. Баумана, но через два года работы сменил сферу на IT, а ещё спустя год — добрал необходимые знания в курсе «Системный аналитик» в Яндекс Практикуме. В этом тексте расскажу про свой путь и дам несколько советов тем, кто ищет себя или делает первые шаги в профессии.

Вы запустили LLM-инференс в продакшене. Поток запросов не менялся, нагрузка та же, что вчера, — а Time to First Token внезапно вырос в три раза. Первая мысль: что-то с моделью. На деле причина почти никогда не в модели — она прячется в планировщике, аллокаторе GPU-памяти, очереди стримингового вывода или сети.

Чем длиннее контекст, тем больнее. Для классического attention вычислительная сложность растёт очень быстро. KV-кеш раздувается до десятков и сотен гигабайт, а в облаке всё это происходит на совершенно произвольном трафике: у одного клиента кодовый ассистент, у другого — аналитика на миллион запросов в день, у третьего — голосовой робот. На таких смешанных нагрузках всплывает то, чего не видно на референсных замерах вендора.

“Neymar’s consolation penalty against Norway at the World Cup means his first international goal, scored on his first cap, was in the same stadium (MetLife) as his last international goal on his final cap,” writes Griffin Cant. “Are there any other players who have bookended their international career in a similar way?”

Over 77,000 people were at the MetLife Stadium on 10 August 2010 as Neymar made his Brazil bow in a friendly against the USA. The fresh-faced, dodgy-haircutted 18-year-old scored after just 28 minutes, a thumping header past Tim Howard in the USA goal. Nearly 16 years later, he rolled his penalty – his 80th goal for his country on his 130th appearance – past Norway’s Ørjan Nyland at the same end of the stadium as Brazil exited the World Cup in the last 16 and followed it by announcing his retirement from international duty.

The 2022 semi-finalists have delighted fans at home as the continent’s other sides struggle with off-field problems

Over the past six decades, Morocco have achieved several performance milestones for Africa at the World Cup. The first country to qualify directly, for the 1970 finals in Mexico, they returned in 1986 and became the first team from the continent to make the last 16, then made that impressive semi-final run in Qatar four years ago.

Even if the Atlas Lions fail to match their 2022 performance, by losing to France on Thursday , they have made tournament history as the first African team to reach the quarter-finals at successive World Cups.

Продолжаю серию подборок. До этого рассказывал про инструменты для первого виртуального сервера и 10 онлайн-сервисов для сетевиков. А сегодня собрал утилиты, которые помогут найти, куда делось место, протестировать скорость диска и отследить, что именно его грузит. Интересно? Заходите под кат. 

Я давно хотел купить плату с Zynq-7020, да такую, чтобы на ней был FMC LPC разъем на который, к примеру, можно было бы установить плату c AD9361 или множеством портов Ethernet, или еще какой-нибудь вариант. И на просторах китайского Aliexpress мне попалась одна такая - TZT RK-ZYNQ7020-F версии 1.1. Я не долго думая сразу ее прикупил и решил что это как раз то, что нужно. И в этой статье хотел бы поделиться своими впечатлениями и обзором того, что на этой плате любезно нам предоставил разработчик. Это будет обзор в несколько ином ключе, без пересказа schematic, а в виде подробного инженерного обзора по подсистемам. Сначала рассмотрим комплектацию, стоимость, затем архитектуру платы, ее внешний вид и что на ней есть. Потом заглянем в питание, reset, clocking и boot. Затем память: DDR3, QSPI, eMMC, microSD. Далее интерфейсы PS: UART, USB, Ethernet, I2C, интерфейсы PL и расширения: FMC, 40-pin, HDMI, MIPI, CAN, RS485, LCD. И в конце - общее впечатление, риски и выводы. Поехали!

Всем интересующимся - добро пожаловать под кат!

Солнце является не только центром нашей планетарной системы, но и одной из причин существования жизни на Земле. Солнечный свет является набором электромагнитных излучений, которые представлены ультрафиолетовым излучением, видимым светом и инфракрасным излучением. Ультрафиолет занимает около 5% по энергии от всего Солнечного излучения. Тем не менее именно с ним связано множество технологических процессов, от очистки воздуха до полимеризации пломб. Ультрафиолет обладает массой перспективных применений, если бы его было «больше». Ученые из Университета Кюсю (Фукуока, Япония) разработали твердотельную систему, способную конвертировать видимый свет в ультрафиолет. Из чего состоит данная система, как она работает, и где может быть использован созданные ею ультрафиолет? Ответы на эти вопросы мы найдем в докладе ученых.

Patrick Wintour reports from the funeral of Ali Khamenei as the Iranian regime puts on a show of confidence and resilience.

Iran is holding a multi-day funeral for its former supreme leader Ali Khamenei in a show of defiance and resilience after its war with the US and Israel. Patrick Wintour, the Guardian’s diplomatic editor, is there. “I’m just one dot on those numbers you’re seeing from helicopters. When I was in the mosque yesterday, it was absolutely rammed, packed, and people couldn’t get into the mosque. There were clearly more than 50,000, 60,000 there.”

Khamenei had ruled for 36 years until he was killed in the first day of airstrikes in February. After such a shocking start to the war, it seemed as though Iran was facing an existential threat. Instead, explains Robert Malley, a US special envoy for Iran during Joe Biden’s presidency, the ceasefire deal being negotiated is in Tehran’s favour.

В прошлых статьях я уже подробно разобрал базовую инфраструктуру Matomo: как развернуть систему на собственном сервере LAMP, рассчитать нагрузку, выстроить правильную архитектуру сайтов, measurable и Roll-Up аналитики внутри Matomo. Но вся эта серверная часть — только фундамент. 

И сегодня мы наконец переходим к самому важному слою Matomo — tracking-коду и архитектуре отслеживания пользовательских действий.

Наша команда создаёт сервис управления доступом (коротко - СУД) в одной из самых больших в Сбере платформ - Платформе Кибербезопасности, или просто ПКБ. На ней обрабатываются все данные Банка, связанные с кибербезопасностью, а также работает множество продуктов и сервисов, предназначенных для противодействия внутреннему и внешнему мошенничеству, защиты инфраструктуры, а также для мониторинга и анализа различных угроз. Подробнее о том, что собой представляет ПКБ, можно посмотреть в Кибрарии Сбера в статье Аналитическая платформа кибербезопасности. Опыт Сбера. Там же можно узнать, как наш сервис вписан в платформу.

В вводной части немного расскажу об архитектуре сервиса, его задачах, с чем мы уже справились и что ещё предстоит сделать и почему.

Наш сервис используется в большой гетерогенной среде, которая содержит не только разрабатываемое в банке программное обеспечение, но и opensource-продукты, предоставляющие различную функциональность (Apache Flink и MLFlow), а также управляющие данными (Apache Hadoop, Ozone и Clickhouse).

This reboot of a 2000 film, based on a script by the great Ingmar Bergman, features some extremely odd camera work and a very strangely written female lead. But it’s frequently bewitching

The film Faithless, a cruel adultery fable directed by Liv Ullmann from a screenplay by the great Ingmar Bergman, was something of a throwback even when it came out in 2000: that sort of sensual dissection of arty middle-class mores was no longer common cinematic currency. Arthouse indulgence hadn’t died out altogether and it still hasn’t today, but, for generations of viewers in 2026 weaned on premium streaming, the lofty waft of the new Faithless TV reboot, adapted from the Bergman scripts by Sara Johnsen and directed by Tomas Alfredson (Let the Right One In, Tinker Tailor Soldier Spy), might seem alien.

We’re smoking on planes and wearing corduroy suits in deep maroon: yes, it’s 1977 and, in Stockholm, actor Marianne (Frida Gustavsson) and her pianist husband Markus (August Wittgenstein) are visited by Markus’s oldest friend David (Gustav Lindh), a wannabe film auteur who’s returned from London bruised by his divorce. Episode two introduces a second timeline, in the present, where lauded director David (Jesper Christensen) and veteran performer Marianne (Lena Endre, who was the younger Marianne in the Ullman movie) meet again and reflect on the damage caused by their affair.

Faithless aired on Sky Atlantic and is on Now

На Kaggle завершился шестой эпизод Playground Series, и тема на этот раз была астрономическая: по горстке чисел определить, что перед нами: звезда, галактика или квазар. По этому выпуску я решил собрать почти исчерпывающий разбор EDA.

Shoppers urged to seek quality products or alternatives as data shows demand surpassing last year’s total

Britons are expected to buy nearly 8m mini fans this year as they are “surging on to the market” in the hot weather – but almost half of those are expected to be low-quality products that end up in landfill within a year.

Waste managers and recycling campaigners have raised concerns as the number of online searches for electrically powered handheld fans, which sell for as little as £2, has already surpassed that seen in the whole of 2025 in the first six months of this year.

Sumitra Peries’ 1978 film about teenage sisters and thwarted romance is laden with passions that can’t be spoken aloud

Here is a gem of South Asian cinema from 1978, by the Sri Lankan director and editor Sumitra Peries. With its lucid monochrome cinematography and calm, natural, unselfconscious performances, there is a freshness and warmth to this film. It is often on the brink of melodrama or soap opera, many shots having a tendency to slow zoom into the actors’ faces, and yet The Girls is in fact rather understated. A great deal of its poignancy resides in this very suppression of emotion. We are in a world of passions that can’t be spoken aloud. It is a story through whose entire running time I wistfully hoped for a happy ending, but that is what Peries ruthlessly withholds from her audience.

Kusum (Vasanthi Chathurani) is a studious, serious teen from a poor family with a scholarship to a very good school. Her father is seriously ill and her mother works hard to make ends meet. She has a rather tense, quarrelsome relationship with her sister Soma (Jenita Samaraweera), who is naughtier, flightier and always receiving letters from “pen pals” – boys. Kusum’s sobering story is triggered in flashback by the sight of a visiting local dignitary, the “divisional revenue officer”, being welcomed to her village.

From Desiderius Erasmus to Luis Rubiales, a cultural history of this most intimate of gestures

If, on a European holiday, you get flustered greeting people – should you kiss? how many times? – spare a thought for Dutch theologian Desiderius Erasmus. Visiting England in 1499, he found a nation of enthusiastic kissers. “Wherever you go, you are received on all hands with kisses; when you take leave you are dismissed with kisses,” he wrote in surprise, or possibly, alarm. On the continent, the fashion for greeting with a peck on the lips had long fallen by the wayside (probably because of sexual propriety), but the English held firm. It didn’t matter if the other person was of the opposite sex, everyone puckered up.

Whether you like to snog, smooch, suck face or osculate (the scientific term), kissing seems so natural and instinctive, it’s hard to imagine it having a history at all. But just as kissing is not seen in all cultures, so, historian of emotions Katie Barclay writes, its meanings have changed across time too. From foot-kissing knights to baby-kissing politicians, to the “shut-up kiss” of Hollywood romcoms, this rich and fascinating history reminds us that kissing is, and always has been, a contested public gesture as well as a private pleasure.

Europe’s longest and most dramatic canyon is replete with exotic wildlife, including kingfishers and beavers, ruined castles and architectural oddities

We’re sipping chestnut kir on a terrace overlooking the Tarn River in southern France when we hear excited voices from the table beside us: “Regard! C’est un castor!” Below us, a beaver the length of my leg is languidly swimming upstream. We don’t need our binoculars because the Tarn is so clean that almost every fish, frog, pebble and ribbon of weed can be seen with the naked eye, magnified by the clarity of the water. This meandering, jade-green river – which winds from its source in the Cévennes national park to Moissac, just north of Toulouse – is home to trout, perch, carp, otters, frogs, toads, kingfishers and herons. We add “beavers” to our list.

Above us, huge vultures have been drifting all day, cruising the thermals in groups of nine or 10. And when our eyes haven’t been on the river or the sky, they have been welded to the many orchids on the bank: including monkey, bee, military, butterfly, pyramidal and fragrant orchids. Later, we discover that 30 varieties have been recorded in this orchid hotspot.

As a child, enduring break after break, I thought of myself as simply unlucky. Truth was, I needed to tune in to my aches, pains and well-founded fears

It was the first day of spring this year. I was topless, face-down on a foldaway travel table, as the masseuse uttered six words that brought my attempt at relaxation to an abrupt end: “I think your arm is haunted.”

I have broken my right arm seven times: seven breaks on seven separate occasions. Some years, my arm was in a sling more than it was out of one. The novelty of getting your mates to cover your cast in that 00s grafitti “S” and the relief of missing the bleep test at school quickly wore off.

Early flight data shows K2 Airways plane crashed into sea with five crew on board south-west of Karachi

Pakistan has located the wreckage of a Boeing cargo plane, the country’s airports authority said, adding that rescuers were searching for the five crew members on board when the aircraft went missing.

The plane was approaching Karachi from Sharjah in the United Arab Emirates when radar showed it “rapidly descending” on Tuesday evening after reporting a “navigational system issue”, according to the Pakistan Airports Authority (PAA).

The regional crossfire raised the risks that an interim agreement to halt fighting in the war could break down, putting the Middle East again at risk of a wider conflict.
