Slashdot reader yeokm1 is the Singapore-based embedded security researcher whose side projects include installing Linux on a 1993 PC and building a ChatGPT client for MS-DOS. He's now sharing his latest project — installing Llama 2 on DOS: Conventional wisdom states that running LLMs locally will require computers with high performance specifications especially GPUs with lots of VRAM. But is this actually true? Thanks to an open-source llama2.c project [original created by Andrej Karpathy], I ported it to work so vintage machines running DOS can actually inference with Llama 2 LLM models. Of course there are severe limitations but the results will surprise you. "Everything is open sourced with the executable available here," according to the blog post. (They even addressed an early "gotcha" with DOS filenames being limited to eight characters.) "As expected, the more modern the system, the faster the inference speed..." it adds. "Still, I'm amazed what can still be acco

An anonymous reader shared this report from the Wall Street Journal: Five years ago, Airbus made a bold bet: The plane maker would launch a zero-emissions, hydrogen-powered aircraft within 15 years that, if successful, would mark the biggest revolution in aviation technology since the jet engine. Now, Airbus is pulling the brakes. The company has cut the project's budget by a quarter, reallocated staff and sent remaining engineers back to the drawing board, delaying its plans by as much as a decade... Airbus has spent more than $1.7 billion on the project, according to people familiar with the matter, but over the past year concluded that technical challenges and a slow uptake of hydrogen in the wider economy meant the jet wouldn't be ready by 2035... Airbus says the past five years of work and money haven't been wasted. The company has established that hydrogen is technically feasible and delaying the project will give it more time to fine-tune the technology, executives said...

For the first time, astronomers have confirmed the existence of a lone black hole," reports Science News — "one with no star orbiting it." It's "the only one so far," says Kailash Sahu, an astronomer at the Space Telescope Science Institute in Baltimore. In 2022, Sahu and his colleagues discovered the dark object coursing through the constellation Sagittarius. A second team disputed the claim, saying the body might instead be a neutron star. New observations from the Hubble Space Telescope now confirm that the object's mass is so large that it must be a black hole, Sahu's team reports in the April 20 Astrophysical Journal.... [And that second team has revised its assessment and now agrees: the object is a black hole.] While solitary black holes should be common, they are hard to find. The one in Sagittarius revealed itself when it passed in front of a dim background star, magnifying the star's light and slowly shifting its position due to the black hole's gravity. This passa

There was excitement when biotech company Collosal announced genetically modified grey wolves (first hailed as a "de-extinction" of the Dire wolf species after several millennia). "But bioethicists and conservationists are expressing unease with the kind of scientific research," writes the Chicago Tribune. [Alternate URL here.] "Unfortunately, as clever as this science is ... it's can-do science and not should-do science," said Lindsay Marshall, director of science in animal research at Humane World for Animals, formerly the Humane Society of the U.S.... Ed Heist, a professor at Southern Illinois University and a conservation geneticist, said the news bothered him. "This is not conservation, but people conflate it," he said. "The point is entertainment...." Naomi Louchouarn [program director of wildlife partnerships at Humane World for Animals], has dedicated her studies and research to the relationship between humans and animals, specifically carnivores like gray wolves. "The reaso

TechCrunch looks at Mechanize, an ambitious new startup "whose founder — and the non-profit AI research organization he founded called Epoch — is being skewered on X..." Mechanize was launched on Thursday via a post on X by its founder, famed AI researcher Tamay Besiroglu. The startup's goal, Besiroglu wrote, is "the full automation of all work" and "the full automation of the economy." Does that mean Mechanize is working to replace every human worker with an AI agent bot? Essentially, yes. The startup wants to provide the data, evaluations, and digital environments to make worker automation of any job possible. Besiroglu even calculated Mechanize's total addressable market by aggregating all the wages humans are currently paid. "The market potential here is absurdly large: workers in the US are paid around $18 trillion per year in aggregate. For the entire world, the number is over three times greater, around $60 trillion per year," he wrote. Besiroglu did, however, cl

"Honeybee colonies are under siege across much of North America..." reported the New York Times last week. [Alternate URL here.] Last winter beekeepers across America "began reporting massive beehive collapses. More than half of the roughly 2.8 million colonies collapsed, costing the industry about $600 million in economic losses..." America's Department of Agriculture says "sublethal exposure" to pesticides remains one of the biggest factors threatening honeybees, according to the article — but it's one of several threats. "Parasites, loss of habitat, climate change and pesticides threaten to wipe out as much as 70% or more of the nation's honeybee colonies this year, potentially the most devastating loss that the nation has ever seen." Some years are worse than others, but there has been a steady decline over time. Scientists have named the phenomenon colony collapse disorder: Bees simply disappear after they fly out to forage for pollen and nectar. Illness disables their r

"Using electrochemistry, University of Oregon researchers have developed a way to make iron metal for steel production without burning fossil fuels..." the University of Oregon wrote last year. "Decarbonizing this step would do roughly as much to reduce greenhouse gas emissions as converting every gas-guzzling vehicle on the roads to electric... If scaled up, the process could help decarbonize one of the largest and most emissions-intensive industries worldwide," replacing carbon-spewing industrial blast furnaces. Paul Kempler, their research assistant chemistry professor, added "The reason we got excited about this chemistry, is that our reactants are two things that are very cheap: saltwater and iron oxide." And this week he announced that "We actually have a chemical principle, a sort of guiding design rule, that will teach us how to identify low-cost iron oxides that we could use in these reactors." "Those reactions conveniently also produce chlorine, a commercially valuable by

"The time has come for me to step away," ArcoLinux lead Erik Dubois posted last week. ("After eight years of dedication to the ArcoLinux project and the broader Linux community...") 'Learn, have fun, and enjoy' was our motto for the past eight years — and I really had fun doing all this," Dubois says in a video version of his farewell post. "And if we reflect back on this teaching and the building and promoting of Linux, it was fun. But the time has come for me to step away..." Over its eight years ArcoLinux "accomplished several important milestones," reports Linux magazine, "such as creating over 5,000 educational videos; the creation of ArcoInstall; the Carli education project; the Arch Linux Calamares Installer (ALCI); the ArcoPlasma, ArcoNet, ArcroPro, and Ariser variants; and much more." According to Dubois, they weren't just creating a distribution but a mindset. Dubois says that the code will remain online so others can learn from, fork, or remix the distro. He also

Discover magazine reports that a team of researchers have produced evidence that the ancient building blocks for water have been here on earth "since early in the planet's history, according to a study published in the journal Icarus." Pinpointing when and where Earth's hydrogen is an essential key to understanding how life arose on the planet. Without hydrogen, there's no water, and without water, life can't exist here. Ironically, researchers turned to a meteorite containing hydrogen to prove that such former bodies did not provide the H2 ingredient of water's H2O recipe. They examined a rare type of meteorite — known as an enstatite chondrite — that was built similarly to early Earth 4.5 billion years ago and the team discovered hydrogen present in the chemical. The logic is that if this material resembling early Earth's composition can contain hydrogen, so too could the young planet.... Since the proto-Earth was made of material similar to enstatite chondrites, by th

Matt Asay answered questions from Slashdot readers in 2010 (as the then-COO of Canonical). He currently runs developer relations at MongoDB (after holding similar positions at AWS and Adobe). This week he contributed an opinion to piece to InfoWorld arguing that DeepSeek "may have originated in China, but it stopped being Chinese the minute it was released on Hugging Face with an accompanying paper detailing its development." Soon after, a range of developers, including the Beijing Academy of Artificial Intelligence (BAAI), scrambled to replicate DeepSeek's success but this time as open source software. BAAI, for its part, launched OpenSeek, an ambitious effort to take DeepSeek's open-weight models and create a project that surpasses DeepSeek while uniting "the global open source communities to drive collaborative innovation in algorithms, data, and systems." If that sounds cool to you, it didn't to the U.S. government, which promptly put BAAI on its "baddie" list. Someone needs
