The Linux Foundation's director of IT infrastructure says they now spend more CPU cycles "rendering commits for scrapers than we spend on all other kinds of legitimate access." At any one time, across 5 geo-distributed nodes, there are 14 CPU cores doing nothing but rendering git commits as html.... [W]hen a source is guaranteed to be LLM-free, like the entire history of kernel commits, it's worth its weight in gold as a source of training data... At the time of writing, linux.git is about 1.48 million commits. Oh, and we have about 922 forks of it on git.kernel.org — but don't worry, it's actually extremely efficient on the backend, since it's mostly the same objects in every fork. Unless, of course, you're a scraper, in which case you have, oh, several BILLION valid URLs you can scrape, only to get 922 duplicates of the same 1.48 million commits — which is exactly what the scrapers are doing. But wait, it's not just commits itself. You can also ask for patches, plain renders, diffs between arbitrary commits — cgit is happy to let you, which was perfect for the times when the Internet was for humans or crawlers who obeyed robots.txt, and is AWFUL right about now, because we can generate 1.2 METRIC BAJILLION valid URLs just for a single fork of linux.git. Initially, this was the solution — look through the logs, find out which IPs are obvious scraper bots, and fail2ban them. At first, this was easy, because the bots helpfully told you who they were via their user-agent. Then, they wised up and started pretending that they were random vanilla browsers. So, we started banning them by IP — after all, it's easy to figure out that an IP that is trying to grab every possible commit in a 8-year-old abandoned fork of linux is not really some lone Chrome on Windows user who is just furiously clicking every link that comes across their screen. The bots then started fanning out to entire subnets, but this was still meh, because obviously an IP coming from Google Compute is just pretending to be a Firefox user... And... that's when things turned really, really ugly. Suddenly, the crawlers were coming from millions of random residential or mobile IPs, all pretending to be random modern browsers. An IP like that would make 4-5 requests and then never show up in the logs again... They descended like swarms of locust, hit hard and fast until the system fell over and then moved on to the next target until you recovered. Then, they returned. Rinse. Repeat. They still do that — welcome to the wonderful world of "proxy SDK monetization." It's big business, and your TV is probably doing it... Today, git.kernel.org receives about 6M daily requests demanding to see random commits. Of these, 66% are still immediately batted away with the Anubis challenge, but 33% are now solving the math and getting through to the main site — because apparently what we have to offer is worth spending a ton of cycles to calculate the Anubis challenge... With a bunch of generous assumptions, legitimate requests are only about 2% of git.kernel.org traffic — everything else are scrapers... [W]e're turning off features to reduce the number of crawlable URLs and to gate off actions that are expensive for us to run. Expect to lose some functionality, at least when accessing our resources anonymously. Trust me, we hate it just as much as you, but at this point it's a necessity... [W]e promise to still offer all of our data for download to anyone who asks. You just may have to jump through more hoops to get it. Sorry.

In May Chess.com "quietly launched" a free educational poker site named Gambit, reports The Verge, where players can learn the game and improve an Elo-like rating without risking real money. And next Chess.com will expand into more classic games, including go, backgammon, and mahjong: Like Gambit, Chess.com is developing Elo-style rating systems for these games, as well. [Chess.com's chief growth officer, Albert Cheng] didn't say when the new sites will launch but that "development is moving quite rapidly" on them, using the same playbook he used for Gambit... He and one other employee took Gambit from prototype to launch within a year, partly with help from AI, mainly for coding tasks. "I think the biggest advantage that it's provided is essentially being able to read our existing codebase and our design system and apply consistent patterns to how we develop Chess.com over to a different platform and do so quickly," Cheng said.... "Just because code is easier to write doesn't mean that you just let it run on its own, but it certainly is a superpower in getting things off the ground." Cheng also said the version of Gambit that's live at the time of writing has "zero or close to zero" AI-created assets, which were used in early prototypes. According to Cheng, without help from AI, getting another site up and running would have required a bigger team or "would have been a lot more disruptive to the status quo of building and growing Chess." Now that a "small, scrappy" team can get a new platform off the ground much faster, it's opened the door for Chess.com to dip into more games, starting with poker. The poker site already has 75,000 members, according to a blog post Friday — and they've already played nearly 20 million hands and completed 100,000 lessons. The site is now holding a daily poker tournament, and on Monday will broadcast the event with live commentary on their Twitch and YouTube channels.

It's already happened — at least on Google Maps. Google's online maps reflect name changes in official government sources, Google posted Saturday. So when the U.S. Geographic Names Information System formally changed the name for "Lake Ontario" to "Lake America," Google also renamed it "Lake America" — for visitors from the U.S. "Those in Canada will continue to see 'Lake Ontario'," Google said. And people from every other country in the world... "will see both names." Though here's how it will be written... Lake Ontario (Lake America) "These updates follow our long-standing policy for bodies of water with names that vary from country to country, and are starting to roll out now." Meanwhile, NPR reports that Ontario's Premier posted a billboard reading "Lake Ontario — Now and Always" on Canada's side of the lake (repeating the message in French). And The Daily Beast reports Google move has also drawn some criticism online: "Hey you gave one of the Great Lakes the wrong name; pretty embarrassing mistake so you might want to fix that," one user wrote on X... MapQuest has said it will not be changing the name, and instead launched a new tool that allows users to rename it themselves to whatever they want.

America's public education system has become "an avenue for multitrillion-dollar companies to enact their agendas," argues a NewYork Times reporter who's covered that tech industry influence for over 10 years. Big tech companies "advocate for new laws to require schools to teach industry-aligned subjects. They sit on committees that help shape learning standards for public school students..." The reporter concludes that "Silicon Valley's efforts to capture the attention of education professionals and provide student training materials can also double as marketing or indoctrination." They enable some of the most powerful corporations on the planet to spin rosy technology stories for administrators, teachers and students, giving them a sanitized view of industry practices and product risks. Many parents would likely object if, say, Exxon Mobil wrote their children's environmental science curriculum. Or if Purdue Pharma trained their children's biology teachers. Yet, over the last decade, schools have often embraced the technology industry in similar ways with few questions asked. The article excerpts the soon-to-be-released book " Coding Kids: Big Tech's Battle to Remake Public Schools," with the reporter adding more thoughts on LinkedIn: Every few years, Silicon Valley has urged American public schools to quickly adopt the latest technology or teach the latest tech subject: Big Data analytics; laptops for every child; algorithm-driven math and reading apps; compter programming; virtual reality. And each time the urgent arguments sounded remarkably similar: if schools just adopted the latest tech tool, or taught the latest tech subject, it would democratize learning for every child and equip students with valuable career skills. Despite good intentions, "today we know some of those classroom tech drives did not exactly pan out as advertised." Now some of the same companies that urged schools to provide laptops and coding lessons are employing similar arguments to urge schools to quickly adopt A.I. tools. I've spent years covering Chromebooks and student chatbot use. And I'm troubled by our collective amnesia around school tech. Thanks to long-time Slashdot reader theodp for sharing the article.

ScienceDaily reports: A microchip about the size of a grain of rice can generate a highly organized "rainbow" of light, a capability that could eventually support faster, higher-capacity 6G communications and extremely precise timing for quantum technologies. Physicists at Loughborough University, working with an international research team, demonstrated a system that produces a series of precisely spaced light frequencies. Those optical frequencies can then be converted into multiple high-frequency electromagnetic signals known as millimeter waves. Millimeter waves are attracting growing interest for future communications because they can provide considerably more bandwidth, giving networks more room to transmit data. A major obstacle, however, has been producing these signals with the precision and stability required for advanced applications... "They could ultimately contribute to faster, higher capacity 6G networks," [said Dr. Luke Peters, of Loughborough University's Emergent Photonics Research Centre], "but the potential goes far beyond communications. These frequencies could also be used in radar systems as well as spectroscopy and astronomical instruments, helping scientists study materials and make extremely precise measurements of the universe. "These applications are still some way off, and there are challenges to overcome before the technology can be used in real-world systems — but our latest work has tackled a major one..." A microcomb generates an extremely precise set of light frequencies arranged somewhat like the colors in a rainbow, although the light itself is invisible to the human eye. A specialized antenna can then convert those optical frequencies into millimeter waves. Earlier research demonstrated that microcombs could produce a single precise millimeter wave frequency. Generating many frequencies simultaneously could be far more useful because each could potentially serve as a separate channel for transmitting information at the same time. Achieving that, however, requires a microcomb with exceptional stability and signal quality. In a new Nature Communications paper, the Loughborough led researchers report a system capable of doing exactly that. Their system connects its chip-based microresonator to a much larger loop of optical fiber where laser light continuously travels through both parts of the system, according to the article. "The team is now investigating how the microcomb system could eventually move from a laboratory experiment into practical technology."

Citrix's Desktop as a Service (DaaS) product includes a lightweight, hardened second operating system called UniconOS (once called "eLux") to offer Windows customers a write-protected file system Citrix says is secure against computer viruses and other malware. Nerds.xyz reports: According to the company, the environment remains isolated from the Windows filesystem and uses Secure Boot protections covering the shim, bootloader, kernel, and initial RAM filesystem. That separation matters when ransomware encrypts Windows or a faulty update leaves the operating system trapped in a boot loop. Instead of repairing Windows immediately, an employee can boot into UniconOS and use Citrix DaaS to access virtual applications and desktops. Citrix SecurAccess with Chrome Enterprise provides access to internal web applications under the organization's existing security policies. In other words, UniconOS does not actually fix the damaged Windows installation. It gives employees another route to their applications while the IT department investigates or repairs Windows... [T]he installer shrinks the Windows volume, creates a new partition, copies UniconOS onto it, and registers the necessary boot entries. Windows remains the default operating system during ordinary use, although administrators can configure boot delays and fallback behavior... The approach could prove useful following a widespread ransomware attack or another defective Windows update resembling the CrowdStrike incident of 2024. Recovery would happen independently on every compatible endpoint instead of requiring IT employees to physically handle thousands of computers.

A team of researchers at Southern Illinois University Carbondale engineered yeast to create cookies that were 3D printed out of plastic waste, reports Futurism: The yeast breaks down the components of plastic compounds and agricultural byproducts like discarded plant stalks into proteins, fats, acids, and flavorings that we can eat. When these are combined together, the mixture is fed into a 3D printer that spits out cookies of any desired shape. The researchers chose to print their cookies as the Greek letter Â, creating what they call "ÂBites" — or micro bites. They haven't actually eaten one of their ÂBites yet, as they wait for university approval... "I think it has a pleasant, appealing aroma," Lahiru Jayakody, a microbiologist at SIU who led the research, told NewScientist. "And it will taste good, too. We've not tasted it, but it smells good — that's for sure — like a real cookie...." The researchers used CRISPR gene-editing technology to reprogram yeast strains to eat polyethylene terephthalate (PET), a widely used form of plastic commonly found in disposable water bottles, food packaging, and clothes, which is rich with carbon. Before the yeast can start feasting, the PET plastics are subjected to a process called oxidative hydrothermal dissolution to break them down into smaller bits that the microbes can digest. The purported advantage of this approach is that it's environmentally friendly, using only heat, water, and oxygen. The yeast feasts on these stripped-down plastic bits, turning them into a slurry of proteins, fats, and acids that're combined with fiber, starch, and sweetener to make them more palatable. One of the yeast strains in particular was able to turn plant biomass into tasty vanilla flavorings... [R]ight now, it's an expensive process, costing around $60 to produce a kilogram of cookies, The Guardian reported. And some experts say it's wishful thinking to believe we can 3D-print, and then eat, ourselves out of these global problems with 3D-printed, delectable treats. "We produce 400 million tons a year of plastic waste. You're not going to turn it all into cookies," Jason Hallett at Imperial College London told New Scientist. "So it's not a solution to the plastic-waste crisis. There's no way you could do this commercially. We're not gonna be eating plastic cookies."

SpaceX is scheduled to launch the Roman Space Telescope on a Falcon Heavy rocket, with the launch window opening at 7:26 a.m. EDT (1126 GMT). NASA will carry the launch live on YouTube. CNN offers this mission overview from NASA Administrator Jared Isaacman. "Roman will investigate dark matter, dark energy and the structure of the universe itself, and accelerate the future of discovery of potentially habitable planets outside our solar system." In fact, "NASA anticipates that Roman will image more than 50 times as much of the sky in the next five years as Hubble covered in three decades," reports USA Today, noting that "every single image it beams back to Earth will contain the equivalent of 100 pictures Hubble would capture." The barrel-shaped Roman telescope is due to set up operations nearly 1 million miles from Earth and begin scouring previously unobservable areas of the cosmos... NASA will make all of Roman's data available for anyone to peruse, meaning astronomers from all over the world will have the opportunity to make use of the observatory for advanced research, NASA says... Spanning 42 feet long and more than 14 feet wide, the Nancy Grace Roman Space Telescope is outfitted with two primary instruments Its 300-megapixel near-infrared camera is built to look across the universe and study the three-dimensional distribution of dark matter, reports The Conversation. But it's also carrying a coronagraph instrument built to dramatically reduce the glare from distant stars "that will test the technology for future missions that plan to detect Earth-like planets around other stars." The mission's generating some excitement. "Nearly three decades after dark energy's discovery, astronomers are letting themselves hope that a breakthrough is almost at hand," writes Scientific American, adding that cosmologists "are increasingly questioning the validity of their vaunted standard model, although no one can decide exactly what comes next." Roman will chase down three different ways of detecting dark energy, seeking to more precisely define what its effects on the universe are and whether they're changing over time. The first one involves surveying the skies for a special variety of supernova that's so predictable that scientists can use it as a beacon for calculating what a host galaxy's distance is and how fast it's moving away from us — the same technique that first betrayed dark energy back in the 1990s. The second entails mapping large numbers of galaxies to discern huge, faint bubbles in the cosmos that represent the fossilized signatures of sound waves that froze out of the universe's primordial plasma as it expanded and cooled. The sizes of those bubbles scale with the size and growth of the very early universe, offering a powerful probe for studying cosmic change over time. The third tracer uses a technique called microlensing, which reveals clumps of dark matter via their warping of background starlight, to fill in scientists' still incomplete reckoning of matter's cosmic distribution. The Houston Chronicle reports that the telescope will also study rogue planets, isolated black holes, starquakes and planet-forming disks around nearby stars. "Almost regardless of what your scientific interest is, Roman is probably already planning to take observations," Julie McEnery, Roman's senior project scientist at NASA, said during a July news conference." NBC News reports that after the Roman telescope launches, "it's set to spend more than three months journeying to its final destination, located roughly 1 million miles from Earth." Three primary surveys are planned over the course of the Roman telescope's mission. During the largest one, which will last over a year, the telescope will peer through the Milky Way's dense, star-packed center, known as the galactic bulge, building a vast catalog of all the astronomical objects it observes. The second and third surveys will focus on dark matter and dark energy. Axios notes that Roman's primary mirror "is about the same size as that of Hubble's, but at 80% less weight — reflecting huge tech advancements since Hubble was built in the 1970s." And NPR reports NASA began planning the $4.3 billion telescope 15 years ago to search for supernovas to help explore dark energy — when "a call came in from the government office in charge of surveillance satellites." "The National Reconnaissance Office reached out to NASA," [remembers cosmologist Daniel Scolnic at Duke University], "saying, 'We have this amazing satellite sitting in a hangar that we're not using. And what what do you guys think about instead of pointing downwards, we point upwards, and you guys use it?'" NASA said yes. It took some substantial modifications, but now that old satellite is set to become NASA's next major space observatory.... Another goal of the telescope is to spend a month surveying all the stars in the Milky Way galaxy. Julie McEnery is Roman's project scientist. She says even though Roman has broadly the same sensitivity and sharpness of vision as the currently orbiting Hubble Space Telescope, its design lets it do things much faster. "That one month of observations to survey our Milky Way galaxy would take about a century with Hubble," says McEnery.

Petit passage chez Genki pour découvrir une manette unique en son genre, la Manta. A première vue, elle n'a rien d'extraordinaire si on met de côté ses dimensions assez massives à cause de la présence d'un écran dans le bas. Pour autant, la prise en main est confortable avec des poignées qui se placent bien dans les paumes, tandis que les boutons et joysticks sont facilement accessibles. Un écran ? Avec un OS ?! Cet écran de 2.79" très précisément n'est pas là pour faire joli bien qu'on puisse changer le thème du fond, la couleur du texte, etc. D'ailleurs, si on peut effectuer ces actions, c'est tout simplement parce que derrière tourne MantaOS, un système d'exploitation léger qui va permettre de faire énormément de choses. Créer des macros à la volée, c'est classique, alors pourquoi ne pas aller plus loin ? Cet OS est ouvert via Genki Forge, un hub que les développeurs vont pouvoir utiliser pour des outils ou applications divers et variés ; par exemple, on peut profiter de la puissance du contrôleur RP2350 intégré pour lancer un jeu en local.
