À force d’optimiser, l’App Store finit par ressembler à ce qu’Apple a longtemps critiqué ailleurs : une vitrine où le payant se confond avec l’organique. Avec iOS 26.3, certains utilisateurs voient apparaître un nouveau design des annonces en recherche, plus « propre » visuellement… mais nettement plus ambigu. Un A/B test qui change tout : l’ad disparaît dans l’interface Jusqu’ici, […] L’article App Store : Ce que cache le nouveau design des pubs dans iOS 26.3 est apparu en premier sur BlogNT : le Blog des Nouvelles Technologies.

WhatsApp semble emprunter une idée bien connue de Facebook : la photo de couverture. Repérée dans des versions bêta iOS récentes, cette nouveauté ajouterait un bandeau horizontal en haut du profil, au-dessus de la photo de profil ronde, pour donner plus de « présence » visuelle à chaque compte. D’après WABetaInfo, la fonctionnalité a été détectée dans la […] L’article WhatsApp v26.1 : Les profils personnels s’offrent enfin une photo de couverture ! est apparu en premier sur BlogNT : le Blog des Nouvelles Technologies.

Michael BurryJim Spellman/WireImageMichael Burry says AI is a bubble so big that it will tank the market and economy when it pops.The "Big Short" investor said the government will try to help, but "the problem is too big to save."Burry was responding to a post on X about the challenges facing ChatGPT-maker OpenAI.Michael Burry says the AI boom is a bubble of epic proportions, and there's no way to stop it from popping and taking down the stock market and economy with it."The government will pull out all the stops to save the AI bubble to save the market to save the economy," Burry wrote on X late Tuesday. "The problem is too big to save."The investor of "The Big Short" fame issued the dire warning in response to a post by George Noble, a former hedge fund manager and ex-assistant to famed investor Peter Lynch at Fidelity.Noble wrote that "OPENAI IS FALLING APART IN REAL TIME." He pointed to the ChatGPT maker's raft of challenges, including fierce competition from Google's Gemini 3 and other AI models, soaring costs, widening losses, and Elon Musk's lawsuit against it."This is not surprising and will not end with OpenAI," Burry responded on X. The vast sums "being spent and lent by the richest companies on Earth will not buy enough time-by the very definition of mania."This is not surprising and will not end with OpenAI.

"OpenAI is the next Netscape, doomed and hemorrhaging cash," Burry wrote in early December.The contrarian investor, best known for predicting and profiting from the collapse of the mid-2000s housing bubble, has previously said on Substack that he's surprised that the startup "kicked off a multi-trillion-dollar infrastructure race," and he would short OpenAI if it was a public company.America's eight most valuable public companies — Nvidia, Alphabet, Apple, Microsoft, Amazon, Broadcom, Meta, and Tesla — are all tech titans that are betting big on AI. Each has a market capitalization over $1 trillion, and together they're valued at north of $22 trillion.The federal government stepped in to save embattled banks during the financial crisis after determining they were "too big to fail." The decision to bail out financial institutions drew widespread criticism, particularly as many individuals affected by the downturn received limited support. Experts are divided over whether the AI boom is a tech revolution or a temporary euphoria. Jeremy Grantham, a veteran investor and bubble historian, recently said the "probabilities that AI will not bust are slim to none."In contrast, "Shark Tank" star Kevin O'Leary and tech investor Ross Gerber told Business Insider last fall they weren't worried as AI was supercharging productivity and fueling rapid growth.Read the original article on Business Insider

Aliett Buttelman cofounded FazitCourtesy of Aliett ButtelmanAliett Buttelman is the cofounder of Fazit, a skincare and makeup company.Taylor Swift wore Fazit's glitter freckles in October 2024, skyrocketing sales.Buttelman had sent samples to the artist and others around her, hoping they'd be used.This as-told-to essay is based on a conversation with Aliett Buttelman, cofounder of Fazit. It has been edited for length and clarity.When people hear that my company took off after Taylor Swift wore our product, they might assume it was a matter of luck. But really, it was the result of a 360-degree strategy we'd developed to get the product into Taylor Swift's hands.I started Fazit with Nina LaBruna about three years ago. Nina had been a marketing client of mine, and she had pitched me on the idea of entering the skincare patch market. From there, we expanded into cosmetics, which was a truly revolutionary move. We launched glitter freckles — a makeup patch to put glittery spots on the cheekbones — in April 2024, and the product immediately went viral online, selling 100,000 units in its first week.Aliett Buttelman (right) cofounded Fazit with Nina LaBruna.Courtesy of FazitWe felt Taylor Swift embodied the essence of the glitter freckles. There would be no one better in the world to wear it. So, we started sending the product to the wives and girlfriends of Kansas City Chiefs players, to Taylor's make-up artists, and to Sabrina Carpenter, who was opening for her at the time, hoping to catch her attention.My life changed on a Monday night after hot yogaThe night Taylor wore the freckles, in October 2024, I had just come home from hot yoga, and the Monday night football game was already on. The Chiefs were playing, and a content creator noticed the freckles on Taylor and messaged me. When I saw the product on her face, I just started bawling.Taylor Swift wore the Fazit patches for Monday Night Football.Courtesy of FazitA part of me just couldn't believe it. The biggest celebrity in the world was wearing our makeup patches, validating all the hard work Nina and I had put in. But really, I was crying because I knew this moment counted: it was about to open the door to so many possibilities. It was our chance, despite the brand being so young.We did over $1,000,000 in sales in the first 48 hoursWe immediately got to work. People noticed the freckles, but didn't know Fazit was the brand behind them. I started reaching out to as many media contacts as I could and hired a publicist. The next day, I was on CBS and Peacock.Nina handles the back end of the business, and she was just as busy. She had to double the size of our warehouse overnight. Shipping labels were printing nonstop. We generated seven figures in sales within the first 48 hours after Taylor wore the freckles, and our web traffic increased by 4,800%.The Swift effect changed the financials of our companyThe first two months were primarily about staying afloat and avoiding too many cracks in the business. Before the Taylor effect, Fazit only had one employee in addition to Nina and me. After that, we called any friends and family we could, asking for help with fulfilling orders.The influx of sales significantly changed the company's financials. Nina and I initially bootstrapped the company with $13,000 of our own savings. After some success, we raised $200,000 from friends and family. But in the fall of 2024, we only had enough cash on hand to run the business for about five more months.Taylor changed that. We had private equity and venture capital firms reach out, but we haven't needed to fundraise. For the first time, Nina and I were able to take a distribution. Now, we have a business that is so profitable and healthy that we can really focus on the next stage of growth.The explosive growth has brought Nina and me closerA year after Taylor wore the freckles, she donned them again, which gave us another sales boost. This time,…

Business Insider's reporter got no sleep in a reclining seat on an overnight train through Europe.Joey Hadden/Business InsiderI spent 12 hours in a regular seat on an overnight train from Berlin to Vienna.For less than $50, I got a reclining seat in a seating carriage with five other people.I've traveled on Amtrak sleeper cars in private rooms, but I didn't adjust well to the shared space.I got exactly zero hours of sleep on an overnight train from Berlin to Vienna in October 2022. I had taken overnight trains in the US before, but this was my first time on a sleeper train in Europe — and my first time in an accommodation shared with other guests. I spent the 12-hour journey in a seating carriage that held six passengers.Since I wanted to maximize my time exploring during the day, I thought an overnight train would be the best way to travel through Europe. And at $40, it was the cheapest overnight train ride I've ever booked. Ultimately, though, the ride was too uncomfortable to sleep, and I arrived in Vienna feeling too exhausted to explore.To get from Berlin to Vienna in 12 hours, I took the Austrian Federal Railway's OBB Nightjet train.A Nightjet train stopped at a station.Joey Hadden/Business InsiderThe rail line operates overnight routes between Austria, Italy, France, and the Netherlands, and it goes as fast as 143 miles per hour, according to the company's website.Nightjet trains have sleeper cars with seating carriages and bunks of three, four, or six.A full couchette accommodation on a Nightjet train.Nightjet - © ÖBB/Harald EisenbergerI booked the former, which are cabins with six regular assigned seats that deeply recline. Some routes have private cabins, but mine didn't."We recommend the sleeper or couchette car for night travel. There is enough space to stretch out. Seated carriages are recommended for shorter journeys," OBB Nightjet wrote in a statement to Business Insider.A sleeper cabin on an OBB Nightjet train.Nightjet - © ÖBB/Harald Eisenberger"The quality of travel depends not only on the carriages, but also on the route," the statement also said.I used a Eurail pass to travel by train through four countries, but without the pass, my ticket would have cost $40.The author's Eurail pass on a European train.Joey Hadden/Business InsiderTo travel by train, I bought a Eurail pass for $477, which gives access to most European trains for a set number of days.Some trains only require a Eurail pass to ride, while others, including overnight trains, incur an additional discounted price.With my seven-day Eurail pass, the train trip cost $14.
