От AI-тьютора к компании без людей: кого на самом деле развивает EdTech
Если посмотреть на главные тренды EdTech в 2026 году, будущее образования выглядит почти неприлично удобным: искусственный интеллект создаёт учебный контент на лету, подбирает персональную траекторию, отвечает на вопросы в любое время суток и терпеливо объясняет одно и то же столько раз, сколько потребуется;¹ длинные курсы распадаются на короткие модули, которые можно проходить между двумя созвонами, по дороге на работу или буквально внутри рабочего процесса;² симуляции позволяют тренировать навыки без риска испортить отношения с живым клиентом, а компании наконец получают возможность не просто отправлять сотрудников учиться, но оценивать их компетенции, видеть дефициты, собирать индивидуальные планы развития и измерять результат.²³
Всё это звучит разумно — особенно если помнить, каким мучительным, дорогим и часто бессмысленным было корпоративное обучение ещё совсем недавно. Сотню очень разных людей сажали в один зал перед одним преподавателем, выдавали одинаковую программу и потом искренне удивлялись: почему половина участников проверяет почту, вторая половина мысленно решает рабочие задачи, а применять полученные знания не собирается вообще никто. На этом фоне персонализация, микрообучение, AI-тьюторы и обучение в рабочем потоке выглядят не очередной технологической модой, а долгожданным возвращением здравого смысла: человек получает именно то знание, которое ему нужно, именно тогда, когда оно понадобилось, и в форме, которую он способен воспринять.
Проблема в другом. Почти все разговоры о будущем EdTech начинаются с возможностей технологии и заканчиваются ими же — как будто по ту сторону интерфейса находится не живой человек со своим опытом, страхом, усталостью, гордостью и конечным запасом внимания, а достаточно исправный приёмник образовательного контента, которому прежде просто неправильно подбирали частоту. Мы обсуждаем, как сделать обучение доступнее и точнее. И значительно реже задаёмся вопросом, почему взрослый человек вообще должен хотеть бесконечно учиться — и сколько раз за одну профессиональную жизнь он способен без серьёзных потерь пересобрать самого себя.

Claressa Shields has everything – except the rival who could transform her sport
The American has proved again that she’s in a class of her own. But is that a good thing for her sport?
Over the weekend, more than 16,000 fans, including former and current world champions such as Floyd Mayweather, Terence Crawford and Shakur Stevenson, filled State Farm Arena in Atlanta to witness Claressa Shields dominate Kaye Scott.
Shields made quick work of Scott winning by TKO in six rounds after unleashing a flurry of punches against the Australian, whose corner threw in the towel to stop the fight before more damage could be done.

In today’s newsletter: how climate crisis is affecting athletes and what steps are being taken to protect them from rising temperatures
The mercury-shattering European summer pants alongside us on the back straight, looming as we hug the shadows, sweaty sandals on the parched earth. Across Asia, Africa and North America too, inhabitants have endured the warmest July of their lives.
In Toronto, Alex Hutchinson, author of the bestseller Endure: Mind, Body, and the Curiously Elastic Limits of Human Performance, has just come back from an early run. “Here I am in Canada, a famously frosty country, and my general take when I wrote ‘Endure’ in the 2010s was that heat was not that big a deal. Occasionally, people died of heat, often in the deep south of the US, often returning to football practise in August, when they were not prepared, but that was rare.

Привет Хабр! На связи Вика Чекалина из команды «Мультимодальный ИИ» AIRI. Сегодня мы поговорим о том, как выкручиваться, когда вычислительных ресурсов мало и для деплоя необходимо сжать LLM, но так, чтобы потеря в качестве была минимальной. Логично, что нужно использовать дополнительную информацию — например, матрицу Фишера (FIM), которая содержит в себе информацию о важности и взаимодействии параметров модели.
Но FIM реальных LLM слоев просто огромные, и работать с ними напрямую вычислительно тяжело или просто невозможно. Люди придумывают различные упрощения: например, можно отталкиваться от предположения, что матрица Фишера диагональна — это сильно сокращает объём памяти, однако корреляция между различными параметрами слоя теряется навсегда. Мы решили не идти на такие компромиссы и придумали метод, который быстро и легко позволяет параметризировать полную недиагональную матрицу Фишера без потери информации о корреляции.

While the Sicilian city of Messina celebrated its most important religious summer holiday, thieves carried out a heist at the regional museum, making off with several works by Renaissance painter Antonello da Messina.
The thieves stole four of Antonello’s works from the Regional Museum of Messina (MuMe), local officials said on Sunday. The 15th century artist is credited with revolutionizing Renaissance portraiture by popularizing elements of Flemish realism and oil-painting techniques in Italy.
“We are devastated by what happened. They were among Antonello da Messina’s most important and best-known works. It is a tremendous loss for the museum, the city, the community and the art world,” MuMe director Marisa Mercurio told Italian news agency ANSA on Sunday.
“Messina without Antonello is deprived of the very essence of the greatest artist of the European Renaissance,” Enzo Caruso, Messina culture councillor, told broadcaster Sky Italia.
The theft is the latest high-profile heist in the art world. Days before, Italian police said they recovered three artworks by Renoir, Cézanne, and Matisse that had been stolen from Parma’s Magnani Rocca Foundation in March. Five people were detained in connection with the theft.
MuMe was closed to the public on Sunday amid ongoing investigations.
Here’s what we know so far about the heist.
How the theft happened
At least three masked people approached the museum at around 9:50 p.m. on Saturday, Italian media reported, citing museum officials and preliminary investigative materials. The theft took place during the Vara procession marking the Ferragosto holiday, which commemorates the feast of the Assumption of the Virgin Mary.
Italian media outlet TempoStretto reported that part of the perimeter railing near a side gate of the museum appeared bent or cut, and an exterior door had been forced open. The thieves appeared to target the Antonello works, going directly to the rooms after entering the museum, according to newspaper La Sicilia.
The theft took place over a few minutes, local media reported.
Marisa Mercurio, director of the museum, told Italian media that the museum’s alarms and cameras were working. Police are investigating how the thieves managed to bypass the security system. Investigators are reportedly reviewing surveillance footage of the theft.
What was stolen
All five surviving wooden panels of the San Gregorio Polyptych, an altarpiece signed and dated to 1473, were removed, while another small double-sided panel was removed from a secure display case. But authorities later recovered two of the polyptych panels that appeared to have been abandoned on a low wall outside the museum. A citizen had noticed the abandoned panels and made the first call to police.
The San Gregorio Polyptych, commissioned for the San Gregorio monastery, originally consisted of six panels but an upper-central panel believed to have portrayed the dead Christ supported by angels disappeared possibly in the 16th century. The surviving polyptych was seriously damaged in an earthquake in 1908 and subsequently underwent restoration, although large portions of lost paint were not reconstructed.
Of the remaining five panels, the two upper panels depicted the “Annunciation of the Virgin.” The middle panel portrayed “Madonna and Child Enthroned,” flanked on either side by depictions of Saints Gregory and Benedict.
The work, considered one of the masterpieces of the Sicilian Renaissance, was the only by the painter to have never left his home city of Messina. Antonello is believed to have been born around 1430 in Messina.
Another work, a small double-sided panel portraying the Virgin Mary and Child with a Franciscan friar in adoration on one side and the dead Christ in Pietà on the other, was also stolen. The painting is dated to between 1465 and 1470. The work was attributed to Antonello in 2003 and acquired by Sicily at Christie’s auction house that same year. Based on its small size, it is believed to have been created for private worship.
No official valuation of the stolen paintings has been made public, but art experts have estimated that they are worth around 70 to 80 million euros ($81 to 92 million).
Earlier this year, Italy acquired Antonello’s devotional painting “Ecce Homo” for $14.9 million from Sotheby’s in New York.
Although “Ecce Homo” is housed permanently in Abruzzo, Messina had hoped to capitalize on increased international interest in the artist following the acquisition. The city was in the midst of developing its “Messina, Città di Antonello” initiative which included exhibitions and other cultural events, as well as a possible new museum dedicated to the artist.
What comes next
Prosecutors in Messina opened an investigation into the theft. Several officials, including Caruso, suggested that the heist could have been carried out by professionals or on commission for the black market, although the prosecutor’s office have not confirmed any theories.
Investigators are reportedly also interviewing museum staff to determine how the thieves managed to evade security.
But some observers have criticized the museum’s security arrangements after the theft, raising concerns about staffing levels. Others have criticized the broader political and administrative management of Sicily’s cultural heritage.
The heist has reminded many of Sicily’s most notorious art theft from more than half a century ago. In October 1969, thieves entered Palermo’s Oratory of San Lorenzo, cut Caravaggio’s “Nativity with Saint Francis and Saint Lawrence” from its frame and carried it away. The painting, which had hung in the oratory for more than three centuries, has never been recovered.
Selling famous stolen art through legitimate channels is virtually impossible. “Stealing an Antonello may be far easier than selling one. If these are ordinary thieves, they will soon discover that—to their cost,” Lynda Albertson, director of the Association for Research into Crimes against Art (ARCA), told the Italian daily La Repubblica.
Rather than selling the artworks, stolen art is instead often used as collateral among criminals for other illicit activities, Albertson said.
Last year, a similarly brazen theft at the Louvre in Paris, France, put international attention on museum security. In October, thieves broke into the Louvre’s Galerie d’Apollon in broad daylight and escaped with eight pieces of crown jewellery valued at 88 million euros. Although several suspects have been arrested, the stolen jewels remain missing.

The director’s cut includes a host more body parts but no more insight into the villains’ personalities. What could be a gothic masterstroke is turned into a dreary procedural in the snow
Warning: this article contains spoilers
Everyone loves a director’s cut. But unlike some, The X-Files: I Want to Believe – Vrach Frankenshteyn, which debuted on Friday on Disney+, is not the kind of director’s cut that will radically alter critical perspectives on the original 2008 film. Much has been made, mainly by director and X-Files creator Chris Carter, of the new version’s grisly additions. But there is still so much about this movie that is underwritten, preposterous and lacking in basic dramatic intrigue that upping its body horror quotient merely makes the same old problems slightly more unpleasant to look at. Perhaps unsurprisingly, this new version is hidden away behind the “Extras” tab for the original film.
For those who have sensibly forgotten, I Want to Believe reunites Mulder (David Duchovny) and Scully (Gillian Anderson) several years after their departure from the FBI, when a female agent disappears and the bureau’s only lead comes from a disgraced former Catholic priest (Billy Connolly) who claims to be receiving psychic visions. So far, so X-Files. The priest, Father Joe, is a convicted paedophile who abused dozens of altar boys, which gives Scully some fairly understandable reservations about accepting his apparent supernatural gifts at face value.

Путеводитель по сертификациям DFIR-специалиста
Привет, Хабр! Меня зовут Артем Семагин, я ведущий аналитик киберкриминалистики в «Инфосистемы Джет». Пожалуй, один из самых популярных вопросов, который задают начинающие специалисты по цифровой криминалистике (да и не только начинающие), звучит примерно так:
Какой сертификат сейчас ценится, что стоит сдавать?
Если немного погрузиться в тему, то оказывается, что выбор совсем неочевиден. На рынке есть престижные сертификации (и очень дорогие) GIAC — GCFE, GCFA, а теперь ещё GX-FA и GLIR. Есть давно известный CHFI от EC-Council, множество вендорских сертификатов, таких как EnCE, ACE, MCFE, Belkasoft и от других разработчиков софта.
В этой статье я решил сделать субъективный обзор наиболее известных DFIR-сертификаций: рассказать о тех, с которыми сталкивался сам, поделиться личным опытом и мнением коллег, а также обсудить, какие сертификаты стоят потраченных времени и денег, а какие можно спокойно пропустить.

I’ve started writing to my sister, my mum, my friends … Not everyone writes back, but when we connect it’s on a deeper level than any group chat
Last January, I received a letter. Most of my post was predictably boring – a statement from the water company, my credit card bill, the occasional update about my pension contributions – but this letter was different. The envelope felt heavier than the run-of-the-mill ones I was used to. It was postmarked Paris, a place I had little connection to, and, most strikingly, it was addressed in messy handwriting – my own.
I had completely forgotten I’d written it until it turned up on my doorstep. On a trip to Paris the year before, I had visited a letter-writing cafe. The idea was simple: you wrote a letter (usually to yourself), the cafe kept it safe and sent it a year later. So, alongside trying escargots for the first time, I wrote a letter filled with questions about my not-so-distant future and addressed it to my home, in London. What will you be doing? Where will you be living? Do you have a boyfriend?

This mockumentary from low-budget horror veteran Richard Mansfield isn’t the most subtle take on the artist-critic relationship but it has a certain sprightliness
Where Quentin Dupieux’s 2023 theatre hostage-taking comedy Yannick pointed out that inside every punter is a critic, this no-frills British mockumentary suggests that if artists aren’t literally haunted by their reviews, then their inner critic might be just as deadly. It begins as a documentary crew arrive to chart theatre director Martin Beswick (Jonathan Cleaver) and his new production of MR James’s A Warning to the Curious at Nottingham’s Hounds Gate theatre (in real life, filmed at the city’s Arts theatre).
He’s getting to grips with his cast, mostly amateurs apart from egomaniac thesp Colin Collins (Matthew Hunt). One day during rehearsals, one of the auditorium seats suddenly flips up, is eerily cold to the touch and has pistachio shells scattered underneath. The old ham Colin seizes the opportunity for an old Hounds Gate tale: about Cyril Cobb, a legendarily vicious director who sat in that very berth to critique other productions – hence his nickname, “Stalls”. After dying in a freak pistachio-swallowing accident, he has now apparently become, Overlook Hotel-style, part of the furniture. Captured in spectral audio recordings, he is heard opining that this new staging is: “Not … good … enough!”

With a soulful sound and soul-baring lyrics, the Afghan Whigs rode the post-Nirvana boom to the big leagues. Their frontman explains his exploration of the male ego – and how Usher got the band back together
The Afghan Whigs were always heavier than their grunge-era brethren. Not musically – their turbulent, sophisticated rock was rooted in soul and funk, and frontman Greg Dulli says the group only embraced distortion in order to be heard over the volume of metalhead drummer Steve Earle’s playing. “Any kind of jangle wasn’t gonna work.” But Dulli’s lyrics, inspired by the likes of Motown bards Holland/Dozier/Holland, were pitch-black, depicting lovers in co-dependent cycles of betrayal and recrimination. Afghan Whigs songs take place in a world where sin is irresistible, punishment inevitable and some kind of judgment inescapable.
“My songs acknowledge consequence, more than they deal in judgment,” Dulli says, between sips of water in the bar of a London hotel. Forty years on from their formation, the Whigs are resurgent. Their new album, Soft Control, ably holds its own with earlier dark masterpieces such as their 1993 breakthrough Gentlemen, and its bleakly funky conceptual follow-up, 1996’s Black Love – records that affirmed their frontman as alt-rock’s poet of arch romantic dysfunction. “I understood sorrow and loss and loneliness from an early age,” he says. His dad was the youngest of 14; several of Dulli’s uncles died when he was young. “I had been there, so why wouldn’t I explore it?”

Silent retreats are all the rage; hotel guests are embracing ‘hushpitatility’. But won’t this leave us more isolated?
Are we becoming too quiet? As a joyless, intolerant shrew, my kneejerk answer is a predictable “if only” (writing this on a train full of happy holidaymakers isn’t helping). But am I wrong? I find myself confronted with evidence that people are taking the expression “say less” literally. A study recently reported in the Atlantic found that daily spoken word counts declined by around 300 every year between 2005 and 2019. A sample group of 2,197 participants, aged between 10 and 94, wore devices that randomly recorded them as they went about their lives; each year, they spoke on average 338 fewer words than the year before. For under-25s, the decline was even steeper: 451 fewer words.
Even I can see that’s worrying. Spending time with other people is good for our brains, health and mood, while, as the US surgeon general put it so starkly in 2023, “lacking social connection can increase the risk for premature death as much as smoking up to 15 cigarettes a day”.

Republican senator Thom Tillis deplored Trump’s decision to cut US military drills with South Korea, which comes despite military officials from both countries warning that Kim Jong-un’s regime is learning new battlefield expertise, including new drone tactics, from assisting Russia with its war in Ukraine.
Tillis wrote on X:
South Korea has been a solid military ally for over 70 years that possesses exquisite military capabilities. Reducing joint exercises with South Korea does nothing more than free up thousands of North Korea’s troops to support Putin’s systematic kidnapping, torture, rape, and murder of innocent Ukrainian citizens.

There’s something uniquely irritating about being forced to listen to whatever a stranger has decided to watch on their phone. Suddenly, the airport gate has a soundtrack—and it’s a tinny succession of TikToks, action scenes, and FaceTime chatter that no one else signed up for.
As Sammie Walker Herrera, a communication coach, puts it, you might be screaming internally: “When I said I listen to all kinds of music, I didn’t mean your music.”
Still, it’s one thing to object internally—and another to ask the person to turn it down. What if they get angry, ignore you, or turn up the volume out of spite? We asked etiquette and communication experts how to make the request without turning an annoying situation into an altercation.
First, decide whether you need to say anything at all
Sometimes the easiest solution is simply to get out of earshot. Nicole Del Valle Rose, an etiquette coach and founder of the Las Vegas consultancy Poised & Proper, says the most gracious response is often the least confrontational one.
“Etiquette isn’t about correcting every behavior that bothers us,” she says. “It’s about choosing the response that creates the best outcome for everyone.”
If there’s another table open at the coffee shop or plenty of room elsewhere in the train car, relocate. You’ll solve the problem in seconds and spare both of you an awkward exchange. Save the conversation for situations where you’re truly stuck, like on a plane, in a waiting room, or aboard a packed bus.
Talk about the sound—not the person
It can be tempting to make sure the offender knows they’re being rude. Resist the urge.
“You don’t want to immediately put this person on the defensive,” says Walker Herrera, who runs Speak Y’all, a communication coaching business. “Frame how it’s impacting you, rather than that they’re doing something ‘wrong.’”
Plus, you don’t know why their phone is so loud. They might be hard of hearing, or they may not realize how far the sound is carrying. Treating it as a solvable volume problem—not evidence of a glaring character defect—makes it more likely that they’ll cooperate.
Ask a question instead of making a demand
If you’re comfortable engaging for a moment, it can help to open with a little friendliness. Larry Schooler, an assistant professor of communication studies at the University of Texas at Austin, suggests first asking what the person is listening to. After they answer, he recommends saying: “Oh, cool. I was just wondering if you could maybe lower the volume or listen to it privately; I needed to concentrate on something and was just finding it hard to do.”
Showing interest softens the interaction, Schooler says. Most people would feel uncomfortable if the first words they ever heard from a stranger were instructions to stop what they were doing or change their behavior. Giving a reason for the request also helps them understand where it’s coming from, instead of concluding that you simply dislike their music, video, or podcast.
If you’d rather skip the small talk, Michelle Retsky, a speech-language pathologist and founder of Words in Motion Therapy in New Port Richey, Fla., teaches social communication for a living. She suggests starting with a genuine question: “Excuse me, do you happen to have headphones? I’m having trouble focusing, and the sound is carrying over pretty loudly over here.”
That frames the situation as a problem the two of you can solve together, which “takes pressure off of them,” Retsky says. If they do have headphones and agree to use them, problem solved. If they don’t, follow up with: “Would you mind turning it down?”
Keep it short
There’s no need to deliver a closing argument about the deterioration of public etiquette. The longer you talk, the more uncomfortable—and potentially charged—the exchange can become.
“Short-and-to-the-point requests can be incredibly effective,” says Claudia Johnson, a licensed marriage and family therapist in Seattle. Her preferred script is just five words: “Would you mind using headphones?”
Tone matters more than finding the perfect wording. Ask politely, Johnson says, and assume the person simply didn’t realize they were bothering anyone. Most people will be happy—or at least willing—to turn down the volume.
And if they refuse? Just walk away; don’t argue or try to teach them a lesson. “We can’t change how others act; we can only ask nicely,” Johnson says. “If they say no or act immaturely about it, that says something about them and not if it was OK for you to ask.”
If the noise is making a flight, train ride, or restaurant visit genuinely unbearable, ask an employee to intervene rather than escalating the interaction yourself, Del Valle Rose suggests. And if the person seems agitated or unpredictable, skip the direct request altogether. Your peace and quiet isn’t worth jeopardizing your safety.
Above all, don’t become fixated on finding a magical combination of words that will guarantee a pleasant response. Healthy communication “doesn’t come down to saying the ‘right’ things,” Johnson says. “It’s about having the courage to say what you need in a respectful manner, while giving others the dignity of deciding how they will react.”
The Power of Setting and Declaring a Goal
In September 2022, I set myself a very public personal goal: to run a 5-minute mile.
It was a completely mad idea. I was 58 years old, and, although in reasonably good shape, the fastest I could then complete a mile was in just over six minutes. I had given myself only eight weeks to cut around 70 seconds off my time—a massive improvement that most people familiar with running thought was unattainable.
The appeal of the mile is that it is neither a sprint nor a marathon, requiring a combination of sustained speed and endurance—strong legs, strong lungs, and mental fortitude.
In my quest, age would be a factor. The fastest known mile by a runner over 60 is 4:49, set in 2020 by 61-year-old Dan King, a former University of Colorado athlete. While I am disciplined about my exercise and run seven days a week, my training is casual in its duration and intensity—and critically, I am no athlete. Yet I would be trying to run just 11 seconds slower than the record for someone roughly my age.
I hired a coach and—to make everything transparent and public—announced my goal on LinkedIn. I also approached running experts for their opinion and advice. I encouraged followers of my LinkedIn page to engage with my journey and set stretch goals of their own.
Why would I do this? Why would I set myself up for potential failure in such a public way?
As founder and CEO of Discovery, a global financial services organization started in South Africa with the goal of making people healthier, the challenge was an opportunity to improve my own health while demonstrating the importance of physical activity and encouraging others to lace up their running shoes. Data from Vitality—a business model we pioneered for health and life insurers that tracks over 60 million life years of health and wellness data to reward positive health choices—shows this compellingly: moving from no exercise to just one physically active day per week reduces the risk of death by 36%, with positive knock-on effects for other healthy behaviors and mental wellbeing.
But most importantly, I did it out of a deep, long-standing conviction to illustrate the power of setting and declaring goals: in this case, out loud and in public. Not only would I be motivating myself, but by declaring it publicly and encouraging others to set their own goals, I hoped to spark a chain reaction.
This wasn’t just a personal ambition; it was an experiment in human motivation. Behavioral science explains why goal-setting is profoundly effective.
As rational decision makers facing options under conditions of risk and uncertainty, we think we are motivated to choose the most rational option—the one with the best combination of value and likelihood of occurring. This thinking—codified in the 1940s as “expected utility theory” by game theory founders John von Neumann and Oskar Morgenstern—dominated decision theory for decades.
Expected utility theory assumes a linear relationship between rival potential gains—and between potential gains and losses. But this linear model was challenged in 1979 by Daniel Kahneman and Amos Tversky. Their theory—prospect theory—proposed that losses loom larger than gains, a phenomenon known as loss aversion.
In one experiment, participants reported feeling much worse about losing $100 than they felt good about gaining $100—despite the amounts at stake being the same. A foundational reason is that people evaluate outcomes relative to a reference point, typically the status quo, rather than in absolute terms. This reference point determines whether an outcome is perceived as a gain or a loss. Once a loss is perceived, loss aversion kicks in—an emotional response in which the pain of loss far outweighs the pleasure of gain. Losses are typically felt to be twice as impactful as gains of the same size.
The logic is this: by setting and declaring a goal, we put ourselves on the line. By putting something at stake, we create something to lose. And because avoiding a loss feels psychologically twice as valuable as achieving a gain, setting and declaring bold goals triggers this force, unlocking radical motivation and decisive action. By declaring a goal publicly, I created something to lose: my credibility and public accountability to my followers.
So how did my five-minute mile work out? I began, as all strenuous physical challenges should, with a health check and a baseline fitness assessment (which I also wrote about on LinkedIn). The latter gave me a cardiovascular fitness VO2 max result of 47.7, well above the 41 classified as “excellent” for men my age. My coach set me a brutal training plan, which he thought could—if all went well—slash my time by up to 30-40 seconds.
Over the next month, I stuck rigidly to my training routine. My time was improving: I managed to whittle it down to 5:40, which was stellar progress, but still a long way off from five minutes. I posted weekly “performance dashboard” updates on LinkedIn—and there, too, I saw huge gains toward my other goal of inspiring other people to set profound goals of their own. One person pledged to wrap up their PhD analysis within the year, and another set out to learn a new instrument. One of the most moving posts came from someone undergoing chemotherapy who decided to run about 3 miles in under 30 minutes—then followed up months later to say that even though it had intimidated her to set a personal goal publicly, she had achieved it.
About six weeks into my training, I got impatient. I thought, How can I run at close to 3 minutes per kilometer when I don’t train at that speed? So I pushed a little faster than my coach had suggested. Then, after my run, I went into a full-day board meeting where I sat, barely moving, for ten hours. I went home to do an easy run up a steep hill, and to my horror, I suddenly felt a sharp pain in my calf. I had torn my calf muscle.
I tried everything to fix it, including platelet-rich plasma therapy and hyperbaric oxygen therapy. I was gutted, but I had to face it: my challenge was over.
Of course, I was devastated that I didn’t achieve my goal. I had made the rookie error of going too fast too soon, and I was bitterly disappointed. But I also saw the bigger picture: I had brought my time down to 5:35, and my VO2 max had risen from 47 to 58. Nearing age 60, I was faster and fitter than I had ever been, and my running had leveled up. Moreover, people all over the world had started chasing goals of their own and sharing their progress. My 30 posts over eight weeks had reached close to 12 million people.
So, was it a success or a failure? In the final calculation, it was a success for several reasons. First, it engaged people in the importance of physical activity. Second, it proved my hypothesis: setting and declaring a goal takes you further than you would have gone without one. And third, even if you fall short of the destination, the goal—and the journey—will change you.
After my injury, one of my key takeaways was that I had nevertheless made remarkable progress as a runner. So, I set myself another goal: could I run a marathon again—something I hadn’t done in two decades—and do so at a reasonable pace, given my age? This time, I stuck to my training plan, avoided injury, and the answer was an emphatic yes.
In 2025, I ran the London Marathon in 3 hours, 37 minutes and 40 seconds, a time that put me in the top 20% of all finishers. I could never have achieved that time 20 years ago, let alone before my 2022 challenge. This had a positive knock-on effect: my result in London meant I qualified for the Boston Marathon, and I ran an even faster time in that race.
In my case, one declared goal—even a failed one—led to another. My limits expanded. And in the process, I experienced the transformative power of setting and declaring goals.

Внутри Anthropic работает Model 2 — сильнее всего, что можно купить. Компания оставила ее себе
14 августа Anthropic опубликовала второй Risk Report — 186 страниц о том, насколько опасны ее собственные модели. В разделе с будничным названием "Заметки о невыпущенных моделях" компания между делом сообщила: внутри работает модель под кодовым именем Model 2. Она сильнее Claude Mythos 5 — самой мощной модели, к которой Anthropic вообще кого-либо подпускает; ею пишут код и генерируют данные; выпускать ее не планируют. Axios подал эту строчку как главную новость отчета. Но если дочитать документ, новость там другая — и куда менее уютная.

Suno v.5.5 Custom Model
В последние недели собрал и протестировал 15 пользовательских 1 моделей (CM). Не претендую на полноту изучения опции, но надеюсь, что кому-то мой опыт сэкономит время. Основной вопрос: как на поведение модели влияют материал для тренировки (DS), стили, Lyrics и параметры.
1 идея витала в воздухе, как только народ услышал генерации очень похожие на известных артистов. В Udio/ Suno требовались танцы с бубном, в Sonauto (ныне Treblo) достаточно было ввести имя в промпт. В конце 2024 г. один проф. певец задал мне вопрос: "Как генерить с моим голосом и манерой?". Сделал его RVC-модель, он: "Тембр точно мой, но манера не везде", а с DS для Suno v3.5: "... похоже, и тембр, и манера. А можно, чтобы вообще как я и чистый звук?" Ответ: "Нужна ваша собственная модель".
Кажется, первыми CM предложили Mureka (Personalized Model): DS из 100+ треков (до 4 мин.), разовый платеж $100-200, тренировка ~3 ч. (сам не пробовал). Zaptrem (основатель Sonauto) на запрос о CM ответил, что не раньше v3. Локальные/ "открытые" инструменты я не смотрел (в своё время помучился с RVC на Google Colab и HuggingFace), но … как-нибудь попробую.
Во всех экспериментах с муз. ИИ меня интересовало 2 момента: а) как это устроено; б) как облагородить свои треки — придать правильное и "живое" звучание. Я не профессионал, но мне не нужно, чтобы ИИ за меня сочинял. Думаю, композитору важно самому отвечать за каждую ноту. Хотя можно и так: "Сгенери в моём стиле, а я выберу".
"Наевшись" вариативности с Persona, Your Voice, да и вообще с генерацией в Suno, я решил тестировать CM сразу на ярком материале. У меня не было и нет планов создавать несуществующие песни знаменитостей 2, но с DS из треков известных певцов поведение CM (похоже/ непохоже) должно быть очевидным для многих. Suno не работает с хитами, но пропускает генерации от Sonauto/ Treblo, т.к. мелодия и текст другие. Треки очень близки к реальным артистам — если не фанат, решишь, что просто не слышал эту песню.

PALAU, Micronesia — The ride out to sea was, in a word, unpleasant. The coastal waters of Palau, an island nation in the western Pacific, are typically calm and electric blue, like what you might see on a screensaver or postcard. The country has put in place some of the world’s most rigorous protections to keep its marine environment pristine.
But on this particular morning in July, a super typhoon named Bavi was churning north of us in the Philippine Sea. Clouds darkened the water and battered us with rain as our boat seesawed through the swell toward the horizon.
Our destination was what you might call a coral garden — a patch of coral, about two miles from shore, that scientists had planted over the past couple of years in an effort to rebuild a damaged reef.
I was wet, cold, and nauseated when we arrived. So naturally, I strapped on a mask and jumped in.
Below me, I could see dozens of star-shaped metal structures that researchers had attached to the seafloor. They were studded with corals in all forms and colors: neon blue antlers, fluffy green mittens, baseball-sized brains. Some of the corals looked like a collection of human vertebrae. Others resembled miniature pine forests.
In the past two decades, governments, nonprofits, and even hotels around the world have dedicated hundreds of millions of dollars to replanting coral reefs like this one. Reefs are among the planet’s most endangered ecosystems: Rising ocean temperatures, pollution, and other threats have killed off an estimated 50 percent of live coral globally since the 1950s.
Those steep losses erode the irreplaceable benefits that coral reefs provide. They go far beyond tourism. Healthy reefs lessen coastal flooding from storms like Bavi. They also serve as nurseries and homes for larger animal species, such as endangered sea turtles and valuable fish like snappers and groupers that people eat.
That’s why so much time and money has gone into restoring these ecosystems globally. Including here in Palau. A different typhoon and warming waters had destroyed some of the region’s coral many years ago, which caused the local fishery to decline, according to Sharp Sakuma, the governor of Ngaraard, a Palauan state where the coral garden is located. “It’s our food,” Sakuma said of fisheries. So a few years ago, he asked local researchers to help bring the reef back.
But reef restoration has a fatal flaw.
Rising global temperatures are heating up the ocean and fueling marine heat waves, which kill reefs. That means that much of the coral that people painstakingly plant often ends up dying months or years later — simply because the ocean is too hot. It’s like planting trees to restore a forest that will soon burn in a wildfire. And this raises serious doubts about the role reef restoration can play in the recovery, and ultimate survival, of these iconic ecosystems.
The colorful antlers, mittens, and brains below me, however, were not your typical planted corals.
They were different.
And they may offer a new reason for hope.
These corals had all gone through what you might call a fitness test. In a lab on shore, marine scientists exposed them to extreme heat and scored them for their ability to tolerate warming. Corals on some of the metal stars here got top marks — they appeared resistant to heat. Those individuals may have more of a fighting chance at surviving as ocean temperatures rise.
These sorts of fitness tests for corals are inexpensive and unexpectedly low-tech: They take place in cheap, store-bought picnic coolers, like what you might bring to the park. But by helping researchers identify the hardiest corals, these tests could help overcome one of reef restoration’s greatest challenges.
Subjecting corals to hot water in a plastic cooler may sound ridiculous. Until you consider the stakes and the circumstances: As the planet warms, simply protecting our beloved, life-supporting places is no longer enough to save them. Neither is restoring them to some former state.
To truly help coral reefs endure, we may actually need to reengineer them.
Scattered across a remote stretch of the Pacific is a collection of more than 300 islands, which, together, form the nation of Palau. Many of those islands are no larger than a small house. And because they’re eroding at the base, they look as though they’re floating above the ocean. When you’re out at sea, it’s easy to pretend that you’re flying through the floating mountains of Avatar’s Pandora.
But the real magic is, without a doubt, underwater.
Palau is surrounded by a vast network of coral reefs, many of which are in near-perfect condition. The region has more than 400 coral species — for comparison, the Caribbean has about 70 — which form the base of a thriving marine ecosystem. On just one weekend of diving there, I encountered close to 100 sharks, more than a dozen sea turtles, and three enormous manta rays. (In my more than 20 years of diving, I’ve rarely seen such an abundance of sea life.)
In the last two decades, Palau has become an epicenter for research on how warming affects coral reefs. Part of that is practical: The country’s abundant corals allow scientists to study how different species and populations respond to rising temperatures. It’s also home to a well-equipped marine lab, the Palau International Coral Reef Center.
But there’s also an urgent local need. Palau is deeply dependent on its coral reefs: Its fisheries and tourism make up more than a quarter of the country’s GDP. And while Palau is home to one of the world’s largest marine protected areas — which bans commercial fishing across 80 percent of its national waters — that does little to protect the reefs here from the existential global threat of ocean warming.
Why is heat such a dire problem?
One “coral” is not a single animal but a colony of hundreds or thousands of individual animals, known as polyps. Those polyps are all nearly genetically identical. They grow the colony — the coral structure that you see on a reef — by cloning themselves over and over again.
Polyps fuel themselves, in part, by grabbing particles out of the water with tentacles (up close, polyps look a bit like sea anemones). But most of their food, and much of their color, comes from a kind of algae that lives within their cells. Like plants, that algae photosynthesizes. And it passes the solar energy it generates onto the coral, in return for nutrients and a place to live.
This partnership fails under extreme heat.
When the ocean is too warm, the algae malfunction, and the polyps kick them out. As a result, the corals lose their primary source of food and their iconic color. That’s bleaching. A bleached coral is not dead but starving, and it will die unless the water cools back down.
Yet there’s another key detail here: Some corals seem to resist this heat-fueled bleaching. They appear naturally more tolerant to warming than their peers. And you can actually see this when you’re snorkeling during a heat wave: Some corals will be bone white, whereas other colonies of the same species nearby will appear fully saturated. Heat tolerance is a trait with natural variation, like height or eye color in humans.
It’s this detail that underpins efforts to make reef restoration less futile in a warming world. If scientists can find local corals that can tolerate warming, they can use them to regrow native reefs that might endure some degree of climate change, here and anywhere coral reefs can be found.
What scientists in Palau are trying to demonstrate is how — absent a naturally occurring heat wave — you can identify those heat-tolerant colonies.
On a mostly clear afternoon in July, days before the typhoon grazed Palau, I boated out to a shallow reef with Steve Palumbi, a marine ecologist at Stanford University. He’s tall and thin and has white hair that he often pulls back into a short ponytail.
Once the boat dropped its anchor in the sand, Palumbi and I jumped in, along with three researchers from the Palau International Coral Reef Center (PICRC). I felt like I was swimming in a tropical fish tank. The water was clear and full of silvery fish. A carpet of colorful coral coated the seafloor. Every hole and crevice was occupied — by a giant clam, a spiky starfish, a sea cucumber, a furry crab. The reef was a giant apartment building with a cast of unusual tenants.
I followed Palumbi and the PICRC researchers over to metal structures on the reef that his team had built. They looked like sunken bed frames, and like those metal stars, they were covered in pieces of coral.
These corals are some of Palumbi’s guinea pigs.
Over the last two years, researchers in his lab at Stanford have been subjecting them to a variety of different heat tests and scoring their performance. The concept is simple: Put the corals in a tank, crank up the temperature, and measure how quickly each one bleaches. The colonies that stay colorful as the temperature soars — the “winners” — may be more tolerant to warming.
Why are some corals more heat-tolerant than others?
For years, scientists have been chipping away at this question. We now know, for example, that a polyp’s genetics has something to do with it; like height in humans, heat-tolerance is partly heritable and can be passed on from parents to their kids. The specific kind of algae living in the coral tissue — its solar power-plant partner — matters, too.
Yet there are still big unknowns. Scientists still don’t know exactly how the genes of polyps and algae may combine in some way to influence tolerance. In search of answers, a researcher in Palumbi’s lab, Brendan Cornwell, is running corals through heat tests, and then examining the genomes of the winners and losers in search of clues.
There are several different ways to measure a coral’s tolerance to warming in a lab. Some tests expose corals to moderately high temperatures over weeks, whereas others blast them with extreme heat over days, or even hours. Longer-lasting tests tend to better represent a natural heat wave — what corals will actually face in the years to come. But they’re expensive, time-consuming, and require expertise. That’s a problem for people who are racing to rebuild damaged reefs, especially in poor regions that lack fancy marine labs and funding.
Working with PICRC, the Nature Conservancy, and other partners, Palumbi’s lab has been trying to demonstrate that the quick and cheap version of these heat tests — using picnic coolers to pressure-test corals over a few days — works well enough. They can help identify heat-tolerant corals and, thus, improve reef restoration, all within one work week, and on a low budget.
That afternoon, Palumbi was collecting corals from those metal frames to test at PICRC. Using wire cutters, Palumbi and the other researchers snapped off branches of coral from the individual colonies. Breaking fragments of coral off a colony is not unlike taking clippings from plants — the “donor” colony continues to grow, even as parts of it are removed.
After filling plastic bins with dozens of coral fragments across three species, the researchers brought them to the boat, loaded them into a large container full of seawater, and then we headed back to shore.
It is hard to put a price tag on coral reefs, but those who have tried say it is quite a lot.
The authors of one study published in 2024 estimated that reefs in the Asia Pacific, which includes Palau, Australia, and Indonesia, among other countries, contribute about $25 billion a year on average to the region’s economies for their role in supporting fisheries and tourism alone.
That doesn’t include the damage that reefs offset during tropical storms. Coral reefs are self-regenerating seawalls that can reduce wave energy — dulling the fiercest brunt of a hurricane making landfall, for example — by an average of 97 percent. In the US, economists estimate that reefs save the country more than $1.8 billion a year just in avoided flood damage. Globally, the cost savings from coral reefs are far higher.
So it’s no surprise that people are so eager to rebuild reefs when they collapse.
To restore these ecosystems, people typically harvest fragments of coral from the wild and grow them in a tank on land or in a “nursery” in the ocean. Then they plant them, one piece at a time, on the seafloor, often using an adhesive putty.
Reef restoration has grown into a global project of enormous scale: A network called the Coral Restoration Consortium counts more than 900 reef restoration efforts worldwide led by more than 350 organizations. By one estimate, groups have spent more than $250 million on reef restoration over roughly the last decade.
But as important as those efforts may be, many of them haven’t worked — they haven’t actually helped coral reefs grow back. “Show me a square mile of reef that has been [successfully] restored,” Palumbi said. “There isn’t one.”
At the heart of that failure is climate change: Prolonged bleaching kills off much of the planted coral, undoing a tremendous amount of effort.
One of the most extreme examples of this is in Florida. In the last three decades, organizations have planted tens of thousands of corals in the Florida Keys, which is home to the world’s third-largest barrier reef. I visited in 2022 and saw the progress of restoration firsthand — there were beautiful fields of planted staghorn and elkhorn, two federally threatened coral species. Some colonies were more than a meter wide. I wrote a story about how it was reviving Florida’s reef.
Then in summer 2023, a record-breaking heat wave struck. The reefs turned a ghostly white. And eventually, nearly all of the staghorn and elkhorn coral in the Florida Keys — including the vast swaths of replanted corals — died, becoming functionally extinct. It was one of the more devastating things I’ve seen in my time covering the biodiversity crisis.
There are similar examples from around the world — in Colombia and Costa Rica, for example, along with Indonesia and the Seychelles.
It’s not that restoration groups are unaware of this problem. Scientists have been studying bleaching for many years in search of solutions. In Florida, researchers are testing out what happens if you cross-breed corals from South Florida with colonies from a warm reef in Honduras, which have a natural ability to withstand higher temperatures. Perhaps their hybrid babies will be more likely to survive the next heat wave. But most of these approaches are time-intensive, costly, run by teams of PhDs, or stuck in the lab.
“The lab science is cool,” Palumbi told me. “But it’s going too slowly. We don’t have time to wait.”
The outdoor research space at PICRC looked like a typical marine lab — a labyrinth of pipes and pumps and, of course, tanks full of sea creatures, which in this case included corals, urchins, and giant clams that would abruptly close if you got too close. It looked appropriately science-y. With the exception of one wooden shelf. On it were eight blue and red plastic picnic coolers, in which Palumbi’s team is doing the bulk of its heat testing.
After returning to shore with bins full of coral fragments, Palumbi put some of them into the coolers, which were fitted with small heaters and pumps. The water inside was around 30 degrees C (86 degrees F). That’s the average high temperature for waters in this region, and the baseline for the test he was about to run.
Then Palumbi, rather unceremoniously, cranked up the dial.
Over each of the next four days, the water in half of the coolers would hit a higher temperature, before returning to the baseline of 30 degrees. On day one, for example, it would reach 34; on day two, it would hit 35; and so on. And each morning, Palumbi would assess the fragments for bleaching. Although these tests run for only a few days, they’re meant to mimic what some corals might experience at low tide during a heat wave, Palumbi said.
I visited the lab early one morning, after just one day of heat stress — after the coolers had reached 34 degrees. Palumbi laid the fragments out on a white grid to evaluate their color, ranking them from one (no bleaching) to five (fully bleached). They were shaped like twigs and still had their normal orangy brown color. No bleaching yet. By the next morning, however, the corals appeared more varied: Some were starting to pale and others remained saturated.
On the last morning of the test — after the coolers had reached 37 degrees, or close to 100 degrees F — nearly all the fragments were white, resembling cauliflower florets. They had expelled their algae. And yet a handful of the fragments still appeared mostly brown. Even after getting blasted by extreme heat, they hadn’t bleached.
“Those are the champions,” Palumbi said.
Palumbi believes that quick heat tests like this stand to benefit restoration projects across the tropics. The equipment, including four coolers, costs less than $1,000, according to Courtney Klepac, a researcher in Palumbi’s lab, who studies heat testing. Groups that are rebuilding reefs can essentially run the corals they harvest through these tests, and then only plant the champions.
That’s precisely the idea behind a project Klepac leads called the Coral Futures Academy. She’s been helping environmental groups across the Pacific integrate these low-overhead heat tests into local reef restoration efforts. And these actually include the coral garden I snorkeled during the typhoon: All the pieces of coral there had gone through similar heat tests.
As promising as this approach sounds, however, there is an important caveat: These tests are only useful if they actually predict which corals are more likely to survive under real-world warming. And so far, scientists haven’t proven that.
Previous studies comparing short heat tests to those that are longer and more faithfully replicate a real heat wave show mixed results; the winners of one are often not the winners of the other. It suggests that surviving a short blast of heat requires different skills than withstanding warmth that lasts for weeks.
Some researchers have also measured what happens to corals that went through an even faster one-day test after they were put in the ocean and then experienced a real heat wave. The champions in those rapid tests were not always more heat-tolerant in the wild.
Ilan Bubb, a marine biologist at the University of Amsterdam who’s studied heat tests, says it’s like trying to predict a person’s marathon time based on how well they perform in a sprint. “We know there’s some correlation there, but how good is that correlation?” he said. “How much information you can get about that marathon from a hundred-meter sprint is still just undetermined.”
Palumbi, Klepac, and their colleagues have been exploring this question, too. They’ve compared bleaching scores from heat tests that last for three or four days to those that last for roughly two weeks. The results appear to be similar, Klepac said: On average, the same corals resisted or succumbed to bleaching in both experiments.
Klepac has also studied what happens to heat-tested corals when an actual marine heat wave hits. At the coral garden I visited with those metal stars, PICRC researchers planted the heat-test winners as well as the poorer performers, as a point of comparison. And as Klepac’s unpublished research shows, the winners of the short heat tests survived better during a bleaching event in Palau in 2024, compared to the losers.
“I am probably one of the few people that you will talk to that kind of low-key gets a little excited for bleaching events,” Klepac told me. “It is a very true test of what we’ve been doing. If we’re trying to market this approach, I want to feel confident that what we’re prescribing actually works.”
There are other drawbacks to this testing approach. For one, it relies on a visible trait — whether a coral resists bleaching or not. That trait, however, doesn’t always indicate whether the coral has the genes to resist bleaching. The colony may have just been healthier going into the test than its peers. Two runners, for example, might get different times in a 100-meter sprint, not just because of their genes but because of how much rest they got the night before.
This matters when you’re trying to rebuild a reef: Typically, you want the coral colonies you plant to eventually reproduce and create heat-tolerant babies. That only happens if the parents have heat-tolerant genes.
And there are other traits that corals need to survive, beyond the ability to withstand warming.
“It’s not just about heat tolerance,” said Liam Lachs, a coral researcher at University of Queensland in Australia who has extensively studied the value of different heat tests.

By only planting the corals that perform well on these heat tests, you might miss colonies that have other important strengths, such as the ability to withstand disease. In fact, future research may reveal that testing corals for one of these other traits may ultimately be a better predictor of their survival in the era of climate change, says James Guest, a reef ecologist at Newcastle University in England.
Palumbi readily admits that the short picnic cooler tests are not perfect. But the important question, he says, is whether they are good enough — good enough to start using them now to help reefs as the science around fitness testing gradually improves.
That much is clear, he says, and several other researchers I spoke to agreed. While the utility and accuracy of short heat tests is not yet proven, people who want to rebuild reefs should still use them, they said. For restoration, there simply aren’t many better alternatives.
“It’s quick, it’s easy to do, people can apply it relatively straightforwardly, and it offers some kind of test,” Guest told me. “Coming up with these practical approaches makes sense.”
The sun was still low in the sky as Palumbi and I strapped on our tanks and weights and plunged into the ocean near one of Palau’s floating islands.
Sinking down felt like descending onto an alien planet. There were rolling hills of branching coral and stacks of plate coral the size of merry-go-rounds. Schools of colorful fish flew over them, like flocks of birds across a woodland.
Toward the end of the dive, we came across a single coral colony as large as a suburban home. The surface was lumpy and covered in what looked like large bulbous fingers. Given its size, the coral was likely at least three hundred years old.
When we were back on the boat, I asked Palumbi what he thought of the reef. “It doesn’t get better than this,” he said.
Isn’t it arrogant to think we can recreate, or even fortify, something as complex as a coral reef?
There could have been 200 species of coral on this one reef alone, Palumbi said, some of which may still be unknown to science. If this is what coral reefs are supposed to look like, even our best science probably can’t recreate them.
It seems like our time would be far better spent trying to prevent reefs like this from dying in the first place. “We all know that we have to solve the bigger problem,” Guest said. “If we don’t reduce carbon emissions and we don’t deal with climate change, nothing we do is going to help corals.”
But the way Guest and other scientists see it, restoration — and the science to improve it — is not about recreating thriving coral reefs. The goal is much more humble, and much more depressing: to prevent as many species and reefs as possible from disappearing altogether so that, if and when the planet cools back down, there’s still something left to regrow.
Reef restoration encompasses a broad range of approaches, Guest said, meant to “stop species and populations from going off into an extinction vortex.” It would seem anything that might help that cause even a little bit — including a handful of plastic picnic coolers — is worth a try.

Привет, Хабр! Понадобилось мне в 2026 году установить XPEnology на ESXi, но актуальных инструкций я не нашёл. Восполняем этот пробел.
Инструкция будет полезна администраторам или DevOps, начинающим своё знакомство с XPEnology.

- Ознакомиться с функционалом NAS Synology перед покупкой дорогостоящего оборудования.
- Протестировать установку или настройку новых пакетов.
- Протестировать сценарии перед их реализацией на реальном железе. Например, замену, дисков меньшего объёма на больший. Или обновление DSM 7.2 на 7.3
