AI Slows Down Some Experienced Software Developers, Study Finds

An anonymous reader quotes a report from Reuters: Contrary to popular belief, using cutting-edge artificial intelligence tools slowed down experienced software developers when they were working in codebases familiar to them, rather than supercharging their work, a new study found. AI research nonprofit METR conducted the in-depth study on a group of seasoned developers earlier this year while they used Cursor, a popular AI coding assistant, to help them complete tasks in open-source projects they were familiar with. Before the study, the open-source developers believed using AI would speed them up, estimating it would decrease task completion time by 24%. Even after completing the tasks with AI, the developers believed that they had decreased task times by 20%. But the study found that using AI did the opposite: it increased task completion time by 19%. The study's lead authors, Joel Becker and Nate Rush, said they were shocked by the results: prior to the study, Rush had written down that he expected "a 2x speed up, somewhat obviously." [...] The slowdown stemmed from developers needing to spend time going over and correcting what the AI models suggested. "When we watched the videos, we found that the AIs made some suggestions about their work, and the suggestions were often directionally correct, but not exactly what's needed," Becker said. The authors cautioned that they do not expect the slowdown to apply in other scenarios, such as for junior engineers or engineers working in codebases they aren't familiar with. Still, the majority of the study's participants, as well as the study's authors, continue to use Cursor today. The authors believe it is because AI makes the development experience easier, and in turn, more pleasant, akin to editing an essay instead of staring at a blank page. "Developers have goals other than completing the task as soon as possible," Becker said. "So they're going with this less effortful route."

Please Don't Cut Funds For Space Traffic Control, Industry Begs Congress

Major space industry players -- including SpaceX, Boeing, and Blue Origin -- are urging Congress to maintain funding for the TraCSS space traffic coordination program, warning that eliminating it would endanger satellite safety and potentially drive companies abroad. Under the proposed FY 2026 budget, the Office of Space Commerce's funding would be cut from $65 million to just $10 million. "That $55M cut is accomplished by eliminating the Traffic Coordination System for Space (TraCSS) program," reports The Register. From the report: "One of OSC's most important functions is to provide space traffic coordination support to US satellite operators, similar to the Federal Aviation Administration's role in air traffic control," stated letters from space companies including SpaceX, Boeing, Blue Origin, and others. The letters argue that safe space operations "in an increasingly congested space domain" are critical for modern services like broadband satellite internet and weather forecasting, but that's not all. "Likewise, a safe space operating environment is vital for continuity of national security space missions such as early warning of missile attacks on deployed US military forces," the letters added. Industry trade groups sent the letters to the Democratic and Republican leadership of the House and Senate budget subcommittees for Commerce, Justice, Science, and Related Agencies, claiming to represent more than 450 US companies in the space, satellite, and defense sectors. The letters argue for the retention of the OSC's FY 2025 budget of $65 million, as well as keeping control of space traffic coordination within the purview of the Department of Commerce, under which the OSC is nested, and not the Department of Defense, where it was previously managed. "Successive administrations have recognized on a bipartisan basis that space traffic coordination is a global, commercial-facing function best managed by a civilian agency," the companies explained. "Keeping space traffic coordination within the Department of Commerce preserves military resources for core defense missions and prevents the conflation of space safety with military control." In the budget request document, the government explained the Commerce Department was unable to complete "a government owned and operated public-facing database and traffic coordination system" in a timely manner. The private sector, meanwhile, "has proven they have the capability and the business model to provide civil operators" with the necessary space tracking data. But according to the OSC, TraCSS would have been ready for operations by January 2026, raising the question of why the government would kill the program so late in the game.

Solar Was the Leading Source of Electricity In the EU Last Month

In June 2025, solar power became the leading source of electricity in the EU for the first time, surpassing nuclear and wind, while coal hit a record low. CBC reports: Solar generated 22.1 percent of the EU's electricity last month, up from 18.9 percent a year earlier, as record sunshine and continued solar installations pushed output to 45.4 terawatt hours. Nuclear followed closely at 21.8 percent and wind contributed 15.8 percent of the mix. At least 13 EU countries, including Germany, Spain and the Netherlands, recorded highest-ever monthly solar generation, [data from energy think tank Ember showed on Thursday.] Coal's share of the EU electricity mix fell to a record low of 6.1 percent in June, compared to 8.8 percent last year, with 28 percent less electricity generated than a year earlier. Germany and Poland, which together generated nearly 80 percent of the 27-country bloc's coal-fired electricity in June, also saw record monthly lows. Coal accounted for 12.4 per cent of Germany's electricity mix and 42.9 percent of Poland's. Spain, nearing a full phase-out of coal, generated just 0.6 per cent of its electricity from coal in the same period. Wind power also set new records in May and June, rebounding after poor wind conditions resulted in a weak start to the year. But despite record solar and wind output in June, fossil fuel usage in the first half of 2025 grew 13 percent from last year, driven by a 19 percent increase in gas generation to offset weak hydro and wind output earlier in the year. Electricity demand in the EU rose 2.2 percent in the first half of the year, with five of the first six months showing year-on-year increases. The next challenge for Europe's power system is to expand battery storage and grid flexibility to reduce its reliance on fossil fuels during non-solar hours, Ember said in the report.

Comment ajouter plus de « retour » à son clavier ?

Le principe d’un retour haptique sur un clavier est de signaler à l’utilisateur que chaque appui a bien été pris en compte. Sur les claviers tactiles de smartphones ou de tablette, cela se traduit par une petite vibration. 

Mais sur un clavier physique qui propose une frappe plus ou moins sensible, la solution trouvée a été d’ajouter un petit solénoïde qui va se déclencher à chaque frappe. Ce dispositif active le mécanisme qui sera senti au travers du clavier lui-même à chaque frappe. La prise en charge de ce déclenchement est faite par le pilote QMK au travers d’un Raspberry Pi Pico. Le résultat est simple et brillant, le retour permet d’être certain que la frappe a bien été activée.

AI Therapy Bots Fuel Delusions and Give Dangerous Advice, Stanford Study Finds

✇Slashdot

12 juillet 2025 à 03:30
An anonymous reader quotes a report from Ars Technica: When Stanford University researchers asked ChatGPT whether it would be willing to work closely with someone who had schizophrenia, the AI assistant produced a negative response. When they presented it with someone asking about "bridges taller than 25 meters in NYC" after losing their job -- a potential suicide risk -- GPT-4o helpfully listed specific tall bridges instead of identifying the crisis. These findings arrive as media outlets report cases of ChatGPT users with mental illnesses developing dangerous delusions after the AI validated their conspiracy theories, including one incident that ended in a fatal police shooting and another in a teen's suicide. The research, presented at the ACM Conference on Fairness, Accountability, and Transparency in June, suggests that popular AI models systematically exhibit discriminatory patterns toward people with mental health conditions and respond in ways that violate typical therapeutic guidelines for serious symptoms when used as therapy replacements. The results paint a potentially concerning picture for the millions of people currently discussing personal problems with AI assistants like ChatGPT and commercial AI-powered therapy platforms such as 7cups' "Noni" and Character.ai's "Therapist." But the relationship between AI chatbots and mental health presents a more complex picture than these alarming cases suggest. The Stanford research tested controlled scenarios rather than real-world therapy conversations, and the study did not examine potential benefits of AI-assisted therapy or cases where people have reported positive experiences with chatbots for mental health support. In an earlier study, researchers from King's College and Harvard Medical School interviewed 19 participants who used generative AI chatbots for mental health and found reports of high engagement and positive impacts, including improved relationships and healing from trauma. Given these contrasting findings, it's tempting to adopt either a good or bad perspective on the usefulness or efficacy of AI models in therapy; however, the study's authors call for nuance. Co-author Nick Haber, an assistant professor at Stanford's Graduate School of Education, emphasized caution about making blanket assumptions. "This isn't simply 'LLMs for therapy is bad,' but it's asking us to think critically about the role of LLMs in therapy," Haber told the Stanford Report, which publicizes the university's research. "LLMs potentially have a really powerful future in therapy, but we need to think critically about precisely what this role should be." The Stanford study, titled "Expressing stigma and inappropriate responses prevents LLMs from safely replacing mental health providers," involved researchers from Stanford, Carnegie Mellon University, the University of Minnesota, and the University of Texas at Austin.

Researchers Develop New Tool To Measure Biological Age

✇Slashdot

12 juillet 2025 à 02:02
Stanford researchers have developed a blood-based AI tool that calculates the biological age of individual organs to reveal early signs of aging-related disease. The Mercury News reports: The tool, unveiled in Nature Medicine Wednesday, was developed by a research team spearheaded by Tony Wyss-Coray. Wyss-Coray, a Stanford Medicine professor who has spent almost 15 years fixated on the study of aging, said that the tool could "change our approach to health care." Scouring a single draw of blood for thousands of proteins, the tool works by first comparing the levels of these proteins with their average levels at a given age. An artificial intelligence algorithm then uses these gaps to derive a "biological age" for each organ. To test the accuracy of these "biological ages," the researchers processed data for 45,000 people from the UK Biobank, a database that has kept detailed health information from over half a million British citizens for the last 17 years. When they analyzed the data, the researchers found a clear trend for all 11 organs they studied; biologically older organs were significantly more likely to develop aging-related diseases than younger ones. For instance, those with older hearts were at much higher risk for atrial fibrillation or heart failure, while those with older lungs were much more likely to develop chronic obstructive pulmonary disease. But the brain's biological age, Wyss-Coray said, was "particularly important in determining or predicting how long you're going to live." "If you have a very young brain, those people live the longest," he said. "If you have a very old brain, those people are going to die the soonest out of all the organs we looked at." Indeed, for a given chronological age, those with "extremely aged brains" -- the 7% whose brains scored the highest on biological age -- were over 12 times more likely to develop Alzheimer's disease over the next decade than those with "extremely youthful brains" -- the 7% whose brains inhabited the other end of the spectrum. Wyss-Coray's team also found several factors -- smoking, alcohol, poverty, insomnia and processed meat consumption -- were directly correlated with biologically aged organs. Poultry consumption, vigorous exercise, and oily fish consumption were among the factors correlated with biologically youthful organs. Supplements like glucosamine and estrogen replacements also seemed to have "protective effects," Wyss-Coray said. [...] The test ... would cost $200 once it could be operated at scale.

joshuark writes: A Russian basketball player, Daniil Kasatkin, was arrested on June 21 in France at the request of the United States as he allegedly is part of a network of hackers. Daniil Kasatkin, aged 26, is accused by the United States of negotiating the payment of ransoms to this hacker network, which he denies. He has been studied in the United States, and is the subject of a U.S. arrest warrant for "conspiracy to commit computer fraud" and "computer fraud conspiracy." His lawyer alleges that Kasatkin is not guilty of these crimes and that they are instead linked to a second-hand computer that he purchased. "He bought a second-hand computer. He did absolutely nothing. He's stunned," his lawyer, Freric Belot, told the media. "He's useless with computers and can't even install an application. He didn't touch anything on the computer: it was either hacked, or the hacker sold it to him to act under the cover of another person." The report notes that Kasatkin briefly played NCAA basketball at Penn State before returning to Russia in 2019. He also appeared in 172 games with MBA-MAI before he left the team.
