Using Drones for Cloud-Seeding Can Trigger Rain, Company Claims

✇Slashdot

Monday a company called Rainmaker announced their rain-triggering technology had produced 143 million gallons of freshwater for Utah and Oregon residents — making them "the first private company in history to validate the results of cloud seeding operations." The Deseret News reports: Founded in 2023, Rainmaker uses drones to disperse silver iodide into clouds, then they track precipitation with advanced radar. However, Rainmaker — and every other rain-enhancement company — has been up against the notoriously difficult challenge of validation. Since there is no control set to test, and because the weather is chaotic and variable, the Government Accountability Office declares the benefits of the technology to be "unproven." To overcome this evaluation challenge, Rainmaker flies drones in unique patterns when seeding. Then operators compare distinct radar and satellite features with where their drones operated. As of April, Rainmaker found 82 unambiguous seeding signatures, which show their seeding operations directly caused precipitation. In Utah and Oregon alone, the company said its cloud-seeding efforts have added enough water to match the annual usage of about 1,750 households. However, "this figure likely represents only a small fraction of Rainmaker's total generation this season," the company said in their press release... Their drone precision, combined with their radar systems, have produced satellite images proving a direct correlation between the seeding and precipitation. Some images show cloud holes or regions of depressed cloud tops after seeding. Rainmaker's announcement promises they'll "go forward and continue our mission to refill the Great Salt Lake, end drought in the American West and deliver water abundance wherever it is needed most around the world." (Rainmaker currently operates in Utah, Idaho, Oregon, California and Colorado.) The director of Utah's Natural Resources Department told the Deseret News that with cloud seeding, "cost per unit of water is so low; it really is the smartest thing we can be doing with our money," Ferry said.

What if Tech Company Layoffs Aren't All About AI?

"Running a Big Tech company during Silicon Valley's AI mania may not necessarily require fewer workers or cost less," writes the Washington Post: Amazon, Google and Meta together have roughly the same number of employees now as they did during an industry-wide hiring binge in 2022, company disclosures show. Growing costs for technical workers and related expenses have often outpaced sales recently. The tech giants' big AI bet hasn't yet paid for itself. That means AI might be killing jobs not through its labor-saving wizardry but by increasing spending so much that CEOs are pressured to find savings, giving them cover to consciously uncouple from their workforces. Marc Andreessen, a prominent start-up investor and a Meta board director, put it bluntly on a recent podcast. Big company layoffs are a fix for overstaffing and changing economic conditions, he said, but AI provides a convenient scapegoat. "Now they all have the silver bullet excuse: 'Ah, it's AI,'" he said... "Almost every company that does layoffs is blaming AI, whether or not it really is about AI," Sam Altman, CEO of ChatGPT owner OpenAI, said at a March conference when he listed explanations for AI's unpopularity in the United States. "Recent history suggests Big Tech companies might not be moving toward a future with fewer workers," the article concludes, "but recalibrating to spend the same, or more, on different people and projects." So in the end, "AI might soon reduce hiring," the article acknowledges, "But the reluctance or inability of the largest tech firms to cut too deeply so far could also show that the path to making a workforce AI-ready — whatever that means — isn't a predictable straight line charting declining headcount."

An Amateur Just Solved a 60-Year-Old Math Problem - by Asking AI

Slashdot reader joshuark writes: Scientific American reports that a ChatGPT AI has proved a conjecture with a method no human had developed. A 23-year-old student Liam Price just cracked a 60-year-old problem that world-class mathematicians have tried and failed to solve. The new solution that Price got in response to a single prompt to GPT-5.4 Pro was posted on www.erdosproblems.com, a website devoted to the Erds problems. The question Price solved — or prompted ChatGPT to solve—concerns special sets of whole numbers, where no number in the set can be evenly divided by any other... Price sent it to his occasional collaborator Kevin Barreto, a second-year undergraduate in mathematics at the University of Cambridge. The duo had jump-started the AI-for-Erds craze late last year by prompting a free version of ChatGPT with open problems chosen at random from the Erds problems website. Reviewing Price's message, Barreto realized what they had was special, and experts whom he notified quickly took notice.

Costumed Crowd 'Speedruns' Scientology Building For Social Media Trend

Last Saturday someone dressed as Jesus "was among the dozens of people in costumes and masks seen on a video forcing open the door of a Scientology building on Hollywood Boulevard," reports the Los Angeles Times, "after a tug-of-war with a security guard." The footage posted on TikTok and Instagram shows the group sprinting up and down stairs and clashing with black-shirted security guards, giggling and gasping to catch their breath while church members scream at them to leave. On their way out — as security guards approach armed with fire extinguishers — one of the sprinters stops and dances to celebrate their successful escape, a move reminiscent of a taunt from the video game Fortnite. For weeks, groups of people have barged into two of the church's Hollywood properties, racing through hallways and tussling with security guards, trying to see how far they can get before they are forced to leave by church staff... Church officials say the incidents are not a game and have accused the speed runners of "hate crimes." After dozens on Saturday stormed the Ivar Avenue building that houses an exhibit dedicated to the church's founder, science fiction author L. Ron Hubbard, the external door handles were removed from all three of Scientology's properties on Hollywood Boulevard by Sunday morning. Guards could be seen blocking the doorway to one building on Monday afternoon... No arrests have been made. A report from the Associated Press cites a joke left on one of the videos: that if runners reach the top of the building, they'll find Tom Cruise. One commenter on a recent TikTok video of a speedrun asked why people are doing this, and another user simply replied, "because it's fun." The 18-year-old who started the trend told the Hollywood Reporter his original video has been viewed over 100 million times. "From there on out, I pretty much knew that Scientology was like a free gateway to a lot of views." Vulture notes that "there's even a Roblox re-creation of the trend, made using the 'maps; drawn from actual videos"

Retina Scan for Diabetes Could Also Reduce Deaths During Pregnancy in Developing Countries

This week Bill Gates wrote a blog post about a special camera from medtech startup Remidio, which delivers high-resolution images of a patient's retina in seconds. The camera plugs into a phone running an AI system that watches for early signs of diabetes — all without needing a blood draw, eye dilation, or a dibetes specialist. It's already been used in 40 countries for more than 15 million patients. But that same hardware, with different software, can also flag the conditions that drive so many dangerous pregnancies. Gestational diabetes sharply increases the risk of pre-eclampsia [a spike in blood pressure during pregnancy responsible for half a million fetal deaths every year and 70,000 maternal deaths]... In most of rural sub-Saharan Africa or South Asia, it usually isn't screened for at all, because the standard test requires a lab. A retinal scan offers a different way in. Remidio's device is currently being used in India to screen pregnant women for conditions that drive stillbirth. And researchers are now adapting the same hardware to screen for anemia and hypertension, too... [S]mall, portable, affordable diagnostics in the hands of community health workers are exactly the kind of lever that can start to move a number that hasn't moved in a long time.

Marvel, DC, Game Publishers Launch Rival Events Saturday for Free Giveaways

The once-a-year free comic book giveaway "is splitting in two," according to a local news report. Launched in 2002 by Diamond Comic Distributor, comic book giants like Marvel and DC have historically participated together. But things changed after Diamond Comic Distributors went bankrupt in 2025, "leaving other companies to swoop in and pick up where Diamond left off." The rights to the "Free Comic Book Day" brand were sold to Universal Distribution, which plans to bring Free Comic Book Day back on Saturday. On the same day, Penguin Random House plans to launch a rival event called Comics Giveaway Day. This means you'll still get plenty of free comics, but this time they will be separated, with some coming under the Free Comic Book Day branding and others arriving under the Comics Giveaway Day branding. Free Comic Book Day will include publishers like DC, Image, Dynamite and Archie Comics. Comics Giveaway Day will include publishers such as Marvel, Dark Horse, Boom! Studios and Tokyopop... The other big change coming this year is the introduction of game publishers Wizards of the Coast and Upper Deck to the lineup, as part of Universal Distribution's Free Comic Book Day. Wizards of the Coast is known for its tabletop role-playing game Dungeons & Dragons, as well as its trading card game Magic: The Gathering. Upper Deck is best known for its sports trading cards and entertainment collectibles, along with deck-building games like the Legendary series... In addition to adding these game makers, Universal plans to expand Free Comic Book Day to include what are colloquially referred to as your friendly local game stores. Marvel's offerings this year include a special Alien, Predator & Planet of the Apes one-shot, while D.C. is offering the first chapter of their upcoming graphic novel Aquamanatee. Other comics include Avatar: The Last Airbender — Legends from Dark Horse Comics and Sonic the Hedgehog from IDW Publishing.

GameStop Is Preparing Offer For eBay

GameStop is reportedly preparing a potential offer for eBay, an unusually ambitious move given that eBay's roughly $46 billion market value is nearly four times GameStop's. Reuters reports: GameStop is preparing an offer for eBay as CEO Ryan Cohen pursues plans to boost the struggling videogame retailer's market value more than tenfold, the Wall Street Journal reported on Friday. Shares of eBay, which has a market capitalization of about $46 billion, soared about 14% in extended trading. GameStop gained 4%. The company has a market value of nearly $12 billion. GameStop has been quietly building a stake in eBay's shares ahead of a potential offer, the report said, citing people familiar with the matter. If eBay is not receptive, Cohen could decide to take the offer directly to the e-commerce company's shareholders, the Journal said.

Le samedi, c'est souvent le moment parfait pour parler jeu vidéo, manette en main ou café posé à portée de clic. Jusqu'ici, notre chronique prenait la forme d'un rendez-vous mensuel. Le problème, c'est qu'au fil du temps, nous avions toujours plus de titres à recommander, commenter ou remettre en lumière. Résultat, un seul mois devenait trop étroit pour contenir toutes nos envies. Il fallait donc revoir la formule. Désormais, la rubrique devient quotidienne, avec un thème différent chaque mois afin de garder un fil conducteur clair et agréable à suivre. Pour inaugurer ce nouveau rythme, nous avons choisi les jeux à faire entre amis, en couple, entre frères et sœurs, surtout avec cette personne suffisamment patiente pour supporter vos erreurs répétées. Oui, nous aurions pu citer immédiatement Portal 2 et son mode coopération légendaire, mais ce serait trop simple. Nous allons donc nous concentrer sur quatre jeux qui ont semé un joyeux chaos dans une relation père-enfant, avec cris, rires, conseils inutiles et parfois vengeance passive sur la manette suivante. Et pour ouvrir cette sélection, difficile de trouver meilleur ambassadeur que It Takes Two. […]

Nvidia Jeston : fin de vie anticipée pour certains modules sur fond de crise de la mémoire

Entre des prix trop élevés et des disponibilités impossibles pour un développement industriel, la gamme de cartes Jetson voit ses modèles LPDDR4 totalement abandonnés par Nvidia.

Jetson Xavier NX

Jetson Xavier NX

Comme la majorité des constructeurs de cartes de développement, la gamme de cartes de développement Jetson de Nvidia souffre de la situation de la mémoire vive et, en particulier, de la pauvreté de l’offre en mémoire DDR4/LPDDR4. De Raspberry Pi à Radxa en passant par Friendly Elec et la myriade d’autres constructeurs qui vivent autour de ces produits, grands comme petits, ce secteur va assez mal en ce moment et tous les tarifs augmentent en flèche.

Les cartes Nvidia Jetson équipées de mémoire LPDDR4 sont donc particulièrement touchées. Chez beaucoup de constructeurs, la disparition est passée sous silence, les boutiques ne sont simplement plus livrées. Nvidia informe surtout ses partenaires industriels des mouvements qu’il pratique. La marque communique donc sur « une accélération de la fin de vie de certains modules spécifiques ».

Les Nvidia Jetson sont la partie émergée de l’Iceberg

La liste est donc la suivante :

Les Nvidia Jetson TX2 NX en 4 et 8 Go
L’ensemble des Nvidia Jetson TX2i
Les Nvidia Jetson AGX Xavier de type industriel et les versions 32 Go
La Nvidia Jetson Xavier NX

Ce sont de « vieux » modules, mais qui sont encore largement implantés dans des produits industriels. Tous datent d’avant 2021 et vont suivre un calendrier précis de distribution EOL (End Of Life / fin de vie). Les dernières commandes se feront dans les mois qui viennent et jusqu’au 15 juillet prochain. Elles ne pourront plus être annulées ni retournées. Cela laisse un peu de temps pour les industriels pour faire des réserves avant de changer de modèle vers des solutions de type Nvidia Orin ou compatibles.

Au 15 juillet 2027, Nvidia cloturera les derniers achats de cartes Jetson intégrées dans des produits. A partir de cette date, il ne sera plus jamais possible de commander ces produits.

La majorité des cartes de développement suivent actuellement une voie encore plus brutale. Les prix des composants ont tellement explosé et la quantité de mémoire disponible en format LPDDR4/LPDDR4x a tellement diminué qu’il n’est plus rentable de les produire. Sur une carte de développement imaginée pour une commercialisation à 30$ HT avec 1 Go de mémoire vive, il n’est pas tenable d’acheter le module de mémoire seul à 15$ HT. La réception par ces industriels d’une faible quantité de mémoire par rapport à leurs besoins les oblige à faire des choix et leurs boutiques sont désormais vides.

NanoPi R3S

NanoPi R3S

Je regardais ce matin les disponibilités de certaines cartes sur le marché. Une NanoPi R3S lancée en 2024 avec 1 Go de LPDDR4 était listée à 30$ HT. L’option 32 Go de eMMC était facturée 5$ HT. Aujourd’hui le produit a disparu des pages de son catalogue et on la trouve sur AliExpress en 1 Go sans eMMC à 41.59€ TTC. Les versions avec eMMC ont simplement disparu.

La faiblesse des ventes entraine évidemment une baisse des achats et un renchérissement des autres composants pour les marques. Au final, la situation devient totalement invivable. Le marché des cartes de développement tout entier est dans une crise majeure et je ne  serais pas surpris qu’on voie disparaitre pas mal d’acteurs à moyen terme. Et cela malgré un marché en demande, mais des industriels comme des particuliers qui ont découvert ces produits dans une approche économique qui ne correspond plus à la situation actuelle. On est passé de produits ayant un gros attrait de par leur prix très abordable en amont à des solutions qui ne valent plus forcément l’investissement nécessaire en aval pour le développement et leur support logiciel.
