European tech leaders are pushing back against high-profile VCs urging founders to work seven days a week — slamming the grindset mentality as everything from “toxic” to “childish.”  “Calling on founders to work insane hours nonstop is just bad advice,” Suranga Chandratillake, general partner at Balderton Capital and former CEO of video search engine Blinkx, told TNW. “Even sprinters don’t sprint all the time — rest and reflection is just as important as putting in the work.” His comments follow a LinkedIn post on Saturday by Harry Stebbings, podcast host and 28-year-old founder of London-based venture firm 20VC. “What European founders need to realise [is that] 7 days a week is the required velocity to win right now,” he wrote, implying that they need to match the infamous grind culture of Silicon Valley.       Martin Mignot, a partner at New York-based Index Ventures, rallied behind Stebbings. In a LinkedIn post of his own, he applauded the 9am-9pm, six days a week (illegal) work culture adopted by some tech firms in China. “Forget 9 to 5, 996 is the new startup standard,” he said.  The 💜 of EU techThe latest rumblings from the EU tech scene, a story from our wise ol' founder Boris, and some questionable AI art.

Amelia Miller, co-founder of return-to-work platform Ivee, called Stebbings’ post “unbelievably toxic.” “Only bad founders work 7 days non-stop,” she wrote. “It’s poor time management and a fast track to burnout.” Miller also said she thinks that working such long hours unfairly discriminates against parents and those with responsibilities outside the office.   Chandratillake also warned against taking advice from VCs without experience of starting and running a company. “If you’re a CEO, don’t listen to a jumped-up finance bro in a hoodie who has never done your job telling you how to do it!” he said.  The lively debate comes amid a broader conversation in European tech over whether workplace culture is holding the region back compared to the US or China.  In a podcast interview in March, Revolut boss Nik Storonsky criticised European startup entrepreneurs, saying they weren’t working hard enough and valued work-life balance too highly. Those comments followed another lively social media debate earlier this year about whether French founders lacked the “grindset” to succeed.   However, a recent survey of 128 European founders by early-stage VC firm Antler found that three-quarters of them work more than 60 hours weekly. Almost 20% of them exceeded 80 hours, challenging the notion that European founders don’t hustle.  Chandratillake said he believes that scrutinising work hours overlooks some of the real challenges founders face in Europe, such as access to late-stage financing. That said, the investor thinks there is a time and a place for the grind. “Sometimes founders have to work extremely hard and long hours, but that’s not sustainable all the time,” he said. “Building a successful company is a marathon, it takes endurance.”  European startup founders are the lifeblood of TNW Conference — and we want you there too.

At the same time, gamers around the United States are checking retailers like Walmart, Target, Best Buy, GameStop, and even Costco in search of the next-generation console.On social media platforms like X, Reddit, and YouTube, gamers are sharing photos and videos of long lines and excited crowds outside stores like GameStop and Target. And some lucky gamers are already showing off their successful purchases. While there are dozens of Switch 2 games and accessories available for purchase, gamers looking for the console itself have two options: Get the base Switch 2 console for $449.99 or opt for the Nintendo Switch 2 + Mario Kart World Bundle for $499.99. Of course, both are in short supply, even as Nintendo forecasts selling 20 million units in the next 12 months. You May Also Like The first customers to get their hands on Switch 2 consoles were the lucky players who placed a preorder through GameStop or Best Buy. Both retailers hosted midnight ET launch events around the country, which gave people the chance to pick up their preorders in person. In addition, these retailers will be selling limited supplies of consoles on a first-come, first-served basis, according to their websites.

However, even though the Switch 2 has been officially released, that doesn't mean online inventory will be available right away. Nintendo is only allowing purchases for customers with active, paid Switch Online memberships. And Target previously announced that it wouldn't start selling the console online until Friday (June 6). However, retailers like Best Buy and Walmart promised to start selling the console online promptly at midnight.When preorders officially went live on April 24, gamers promptly crashed retailer websites, and history may repeat itself for launch day.

Klarna’s CEO has warned that software engineers risk being left behind in the AI era — unless they’re also business-savvy. Speaking at SXSW London, Sebastian Siemiatkowski said the talent “who have really accelerated their careers at Klarna” are “business people who have learned to code.” The reason? “They can take their business understanding and turn it into deterministic or probabilistic statements with AI.” This shift, he warned, poses a threat to engineers. “A lot of them have allowed themselves to be isolated with technical challenges only, and not been that interested in what the business actually does,” he said. His message to them was blunt: “Engineers really need to step up and make sure they understand the business.” Siemiatkowski’s comments add another layer to Klarna’s controversial AI transformation. In December 2023, he said advances in the field had led the buy-now-pay-later firm to freeze hiring for all roles — except engineers. A year later, he had an update: the company had stopped bringing on new staff entirely. Register Now Open job listings, however, told a different story. Klarna also recently launched a new recruitment drive to ensure customers can always speak to a human. The apparent contradiction has drawn criticism, but the company is doubling down on automation. Last year, Klarna announced that its OpenAI-powered assistant was doing the work of 700 full-time customer service agents. It also used an AI-generated version of Siemiatkowski to present its financial update — suggesting even CEOs could be automated. The 43-year-old recently claimed that AI can already do “all of the jobs” that humans can do. At SXSW London, he stressed the need to be upfront about the risks. “I don’t want to be one of the tech CEOs that are like no worries everything will be fine, because I do think there will be major implications for white collar jobs and so I want to be honest about it,” he said. Despite the gloom, Siemiatkowski still sees big opportunities for people who blend business acumen with technical skills. “That category of people will become even more valuable going forward,” he said.

News Earth Small earthquakes can have a big impact on the movements of major faults The little quakes can disrupt the growth of slow-slip events along megathrust faults Megathrust faults can generate some of Earth’s largest quakes. One example is the 2011 Tohoku earthquake, which rocked Japan and fomented a tsunami that devastated coastal areas, as shown. These same faults can also release immense amounts of seismic energy over days or weeks in harmless slow-slip events. enase/Getty Images By Nikk Ogasa 15 hours ago Seismic symphonies of minor earthquakes may affect grand movements on major faults. Small and distant earthquakes can disrupt the growth of slow-slip events — gradual fault movements that can release tremendous amounts of energy at gentle tempos, a new analysis of seismic data suggests. Reported in the May 16 Science Advances, the research shows that the more frequently small earthquakes occur near a fault’s slow-slip zone, the less synchronized the slipping becomes. Megathrust faults — massive fractures where one tectonic plate pushes under another — are notorious for hatching Earth’s most devastating temblors. These same faults can also slide steadily for days or weeks in slow-slip events while emitting faint vibrations called tectonic tremor. First identified around two decades ago, these softly humming events can shift stress on faults and may influence the timing of large, destructive earthquakes. But it’s not clear why these enigmatic events can grow for hundreds of kilometers along some faults while remaining restricted to small parts of others.

An artist's illustration of an unlucky massive star approaching a supermassive black hole. Credit: University of Hawai'i Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday. At any given time across the universe, massive cosmic bodies are releasing incomprehensible amounts of energy. Stars burn like celestial nuclear fusion reactors, quasars emit thousands of times the luminosity of the Milky Way galaxy, and asteroids slam into planets. But all of these pale in comparison to a new class of events discovered by researchers at the University of Hawai’i’s Institute for Astronomy (IfA). According to their findings published June 4 in the journal Science Advances, it’s time to classify the universe’s most energetic explosions as extreme nuclear transients–or ENTs. ENTs are as devastating as they are rare. They only occur when a massive star at least three times heavier than the sun drifts too close to a supermassive black hole. The colliding forces subsequently obliterate the star, sending out plumes of energy across huge swaths of space. Similar events known as tidal disruption events (TDEs) are known to occur on a (comparatively) smaller scale, and have been documented for over a decade. But ENTs are something else entirely. “ENTs are different beasts,” study lead author and astronomer Jason Hinkle explained in an accompanying statement. “Not only are ENTs far brighter than normal tidal disruption events, but they remain luminous for years, far surpassing the energy output of even the brightest known supernova explosions.” Hinkle was first tipped off to ENTs while looking into transients—longlasting flares that spew energy from a galaxy’s center. Two particularly strange examples captured by the European Space Agency’s Gaia mission caught his eye. The pair of events brightened over a much longer timeframe than previously documented transients, but lacked some of their usual characteristics. “Gaia doesn’t tell you what a transient is, just that something changed in brightness,” Hinkle said. “But when I saw these smooth, long-lived flares from the centers of distant galaxies, I knew we were looking at something unusual.” Hinkle soon reached out to observatory teams around the world for what would become a multiyear project to understand these anomalies. In the process, a third suspect was detected by the Zwicky Transient Facility at the Palomar Observatory in San Diego. After months of analysis, Hinkle and collaborators realized they were witnessing something unprecedented. An infrared echo tells us that a dusty torus surrounds the central black hole and newly-formed accretion disk. Credit: University of Hawai’i The ENTs analyzed by astronomers displayed smoother, longer lasting flares that pointed towards something very particular—a supermassive black hole accreting a giant, wayward star. This contrasts with a more standard black hole that typically acquires its material and energy unpredictably, resulting in irregular brightness fluctuations. The energy and luminosity of an ENT boggles the mind. The most powerful ENT documented in Hinkle’s study, Gaia18cdj, generated 25 times more energy than the most powerful known supernovae. For reference, a standard supernova puts out as much energy in a single year as the sun does across its entire 10 billion year lifespan. Gaia18cdj, meanwhile, manages to give off 100 suns’ worth of energy over just 12 months. The implications of ENTs and their massive energy surges go far beyond their impressive energy outputs. Astronomers believe they contribute to some of the most pivotal events in the cosmos. “These ENTs don’t just mark the dramatic end of a massive star’s life. They illuminate the processes responsible for growing the largest black holes in the universe,” said Hinkle. From here on Earth, ENTs can also help researchers as they continue studying massive, distant black holes. “Because they’re so bright, we can see them across vast cosmic distances—and in astronomy, looking far away means looking back in time,” explained study co-author and astronomer Benjamin Shappee. “By observing these prolonged flares, we gain insights into black hole growth when the universe was half its current age… forming stars and feeding their supermassive black holes 10 times more vigorously than they do today.” There’s a catch for astronomers, however. While supernovae are relatively well-documented, ENTs are estimated to occur at least 10 million times less often. This means that further study requires consistent monitoring of the cosmos backed by the support of international governments, astronomical associations, and the public.

🍉🍋🐍🍇🍎 "Brainmelting Snake" Serpentes is back An updated offering of blissful boomer arcade goodness is here! It's Snake, but every fruit has 5 effects assigned to it randomly. Eat the fruits to reveal their effects, then use them to your advantage... or die trying. Based on a hellishly addictive hidden gem made by Benjamin Soulé in 2015, this new Serpentes got a second serving of 11 fresh fruits to unlock, mix, and match with the old ones, featuring new mechanics, reworked old ones, and a new original soundtrack by Pentadrangle. Boomer Arcade at its crunchiest Select two bonuses to start your run, then score the best possible score in 60 seconds. Death is inevitable, but dying only means retrying the very next second, as the fruits' properties get reshuffled. As you reach higher scores and fill up the leaderboard, you'll unlock new bonuses to select at the start, and new fruits to mix into the game for new effects. Strategize on the fly The fruits have 5 rows of properties. The first row is simply score. The second one adds and removes lengths of tail. The third one adds enemies, obstacles, it makes your snake faster, and some other fun things. The fourth row makes your next fruit more valuable, or maybe you'll get a wider selection of fruits, or you'll get a way to destroy some of the enemies and obstacles. Finally the fifth row holds a variety of powerful bonuses and mini-games that play through the game of Snake. Complete a row on all the fruits to get 20 extra seconds on the timer. Quickly pick up 5 of a same fruit to unlock its fifth property. Try different priorities. Adapt your strategy to the effects you uncover. Or die and restart. After all, a run is just 1 minute. Pay to win The free demo for this game is essentially the same as the full game. However, the demo only lets you select one starting bonus, instead of two. This makes it considerably harder than the full game, though not impossible, and we believe it's representative enough to get an idea of whether this game is for you. Besides this, the demo mostly features the fruits from the original version, and only 2 of the 11 unlockable new ones. Controls This game plays entirely with the keyboard, or with a gamepad. (keyboard still required to input your name at least once for the leaderboard) Use directions to move your snake, and hold them to move faster. That's it. 🍌🍑🐍🍒🥑 Praise for Serpentes "It captures the spirit of the original Snake perfectly [...] and then dials it up to eleven." — Derek Yu"Each variation of the Snake theme has generally been the same until Benjamin Soulé released 'Serpentes'." — Indie Retro News"[about Serpentes] I love the way it feels in my brain." — The Beauty of Games, by Frank Lantz🍋🍊🐍🥝🍍 This game was partially funded on Patreon by people like you!

Martian "slope streaks" spotted by NASA's Mars Reconnaissance Orbiter in 2017. Scientists previously thought these large, discolored features may be signs of running water. (Image credit: NASA/JPL-Caltech/University of Arizona) Mysterious dark streaks flowing across Mars's surface may not be the result of running water after all, a new artificial intelligence (AI) analysis suggests.The streaks, first observed running along Mars's cliffsides and crater walls by NASA's Viking mission in 1976, were long thought by scientists to have formed as a result of the flow of ancient water across the now mostly desiccated planet's surface.But an AI algorithm trained on slope streak observations has revealed a different origin for the streaks — likely being formed from wind and dust, not water. The findings, published May 19 in the journal Nature Communications, could have important implications for where humans choose to explore Mars, and the places they search for evidence of possible ancient life. "That's the advantage of this big data approach," study co-author Adomas Valantinas, a planetary scientist at Brown University, said in a statement. "It helps us to rule out some hypotheses from orbit before we send spacecraft to explore."The sinewy lines are darker than the surrounding Martian ground and extend for hundreds of meters downhill. The shorter-lived of these features are called recurring slope lineae (RSL), and regularly spring up during Mars's warmer spells.This led some planetary scientists to suggest that seasonal temperature fluctuations could be causing ice or frozen aquifers to melt, or humid air to condense, sending streams of salty water trickling down the planet's craters. If this were true, it would make these regions of particular interest to future Mars missions.To investigate this, the scientists behind the study trained a machine learning algorithm on confirmed streak sightings before making it scan through 86,000 satellite images to create a map of 500,000 streak features.RELATED STORIES"Once we had this global map, we could compare it to databases and catalogs of other things like temperature, wind speed, hydration, rock slide activity and other factors." Bickel said. "Then we could look for correlations over hundreds of thousands of cases to better understand the conditions under which these features form."Using the map, the scientists found the streaks were most likely to form in places where wind speed and dust deposition was high, suggesting that they came from layers of fine dust sliding off steep slopes.Other studies have pointed to tantalizing evidence of water and even life on Mars. If the study findings hold up, they could serve as a guide to sift between the Red Planet's useful leads and its red herrings.
