Tesla's upcoming Cybercab "has been certified at 165 Wh/mi," reports Electrek — which makes it "the most efficient electric vehicle ever produced — by a wide margin." The next most efficient EV on the market, the Lucid Air Pure, consumes 28% more energy per mile. Tesla VP of Vehicle Engineering Lars Moravy confirmed the figure, which represents a certified rating — not a marketing claim or internal target. It's an impressive achievement, but it comes with a massive asterisk: Tesla accomplished this by building a tiny two-seat robotaxi with no steering wheel, no pedals, and a sub-50 kWh battery pack... Even Tesla's own Model 3 — one of the most efficient passenger EVs you can buy — needs nearly a third more energy to cover the same distance... Where the 165 Wh/mi figure genuinely matters is in the economics of running a robotaxi fleet. Energy cost per mile is one of the biggest operating expenses for any ride-hailing service, and the Cybercab's efficiency gives Tesla a structural cost advantage over competitors... The small battery pack also means faster charging times and lower per-vehicle battery costs — both critical for fleet economics. Tesla has said the Cybercab will cost $30,000, and the efficient powertrain is a big part of hitting that price target. Tesla confirmed Cybercab production has started at Giga Texas in April, though the ramp is expected to be slow initially. The company still hasn't solved unsupervised autonomous driving — the first steering wheel-less unit rolled off the line in February, but Tesla's supervised robotaxi fleet currently crashes at roughly four times the rate of human drivers.

Linus Torvalds spoke this week at the Linux Foundation's Open Source Summit North America, reports ZDNet — and described how AI is impacting Linux kernel development: "In the last six months, we've seen a lot more commits," Torvalds noted, estimating that "the last two releases, it's been about 20% more commits than we had in the previous releases over many years.... The real change that happened in the last six months was that the AI tools actually got good enough for a lot of people... we're seeing a definite uptick in just development on pretty much all fronts...." On the positive side, he framed AI-discovered bugs as "short-term pain" with long-term benefits: "When AI finds a bug in any source code... long term is you found a bug, we fixed it, that the end result is better for it." After all, he continued, "I think finding bugs is great, because the real problem is all the bugs you didn't find..." For small teams or solo maintainers, he said, flood-style AI bug reports can cause real burnout, especially when "it's a bug report, and when you ask for more information, the person has done a drive-by and doesn't even answer your questions anymore." The AI news site Techstrong notes this quote from Torvalds. "I have a love-hate relationship with AI. I actually really like it from a technical angle, I love the tools, I find it very useful and interesting, but it is definitely causing pain points." The chief challenge with AI is that it forces people to change how they work, he found. People get into a rut, and AI challenges their norm. The Linux security mailing list got the brunt of this new wave of AI-generated commits. Not all bugs are security issues, but when "people think that when they find a bug with AI, the first reaction seems to sometimes be let's send it to the security list, because this may have security implications," Torvalds said. As a result, the security list — watched over by a small group of maintainers — was overrun by duplicate entries... The Linux project learned to manage the bug influx with a set number of tools to sort out and deprioritize the obvious drive-by reports (ones where the person submitting the report won't even answer any questions). One tool, Sashiko, reviews all the patches submitted on the mailing list. "Sometimes the review is not great, but quite often it finds issues and it asks questions and says, 'Hey, what about this issue?'" he said. Linux also updated their documentation, partly just to address "an uptick in bug and security reports from discoveries made in full or in part with AI."

A proposal to make daylight saving time permanent has advanced in the U.S. House of Representative, reports California news station KCRA: A proposal to make daylight saving time permanent has advanced in the House, reigniting an age-old American debate around the twice-annual clock changes. And this time, the proposal has the president's backing. President Donald Trump said Thursday that he will work "very hard" to sign the so-called Sunshine Protection Act into law after the House Energy and Commerce Committee overwhelmingly approved the bill by a 48-1 vote. The bill still needs to pass the full U.S. House, and then the U.S. Senate would consider taking up the measure. The bill would allow U.S states to decide whether to "exempt themselves" from Daylight Saving Time, according to the article. The bill's sponsor described the annual clock-switching as "inconvenient, unnecessary, and out of step with the needs of today's families and economy," while finally creating a permanent Daylight Saving would bring "more usable daylight hours throughout the year."

Long-time Slashdot reader Sun writes: AMD has announced a change to the way they are licensing Vivado, their FPGA development tool... Hidden between the lines of the announcement [of a new model starting with the 2026.1 release] is the change to the free of charge tier. AMD is adding more devices to be supported in this tier, which is supposedly the carrot. The stick, however, is the removal of certain debug features. The thing that's likely to hit the hobbist community the worst, however, is that the free tier will now not be available on Linux. AMD are saying that old licenses are still in effect, so it appears that if you hurry to install Vivado now, you'd still be able to use it moving forward. It is not clear, however, whether it'll still be possible to install Vivado 2025.2 after Vivado 2026.1 becomes available. "Almost all our surveys show... close to 70% of the customers are still using Windows," explained AMD senior product application engineer Anatoli Curran on the tool's support forum. "Vivado ML Standard Edition v2025.2 is going to be officially supported (I mean if there are any bugs found, these can be fixed) until v2026.3 release... Any release older than the current 3 released versions of Vivado then becomes unsupported (meaning no bugs will be fixed with Vivado Standard Edition v2025.2 after Vivado v2026.3). "However, users can continue using V2025.2 forever, if they wish to do so... Also, Vivado ML Standard Edition v2025.2 is license-free... Users only need to obtain and use any IP Core related licenses, or Vivado Model Composer (for SysGen)."

"The numbers show that layoffs in the U.S. are roughly at or below levels from before the pandemic," reports the Washington Post, "although they are higher than in 2022 when businesses snapped up workers as the economy roared back to life... "A different measure that accounts for the growing U.S. workforce shows that layoffs affected about 1.2% of employed people in March, a number that has been steady for years outside of the pandemic..." In the technology industry, where Meta and other companies are regularly announcing job cuts, the layoff picture is complex. There has been a marked increase in layoffs in recent months in what the Labor Department calls the information industry, which includes employment of software developers and other tech workers. But Matthew Martin, senior U.S. economist at the research and consulting firm Oxford Economics, noted that hiring has also increased in that category, which includes media and entertainment. The combination of hiring minus layoffs in the information industry is effectively a wash, Martin said. Layoffs at Big Tech companies like Meta and other high-profile employers don't necessarily reflect what is happening in the country, Martin said, and draw far more attention than what may be slow and steady workforce growth. "There's a lot more headlines about job cuts than there are [about] expansion plans by businesses," he said. In his view, technology companies may be pushing out some workers and replacing them with people who have different skills as they respond to the demands of AI. It's true that businesses in some industries are devoting enormous sums of money and attention to AI. It's changing how some people work and a minority of American businesses are rolling out AI tools. But it's also become a trend for bosses to blame layoffs on the productive capabilities of AI and its ability to replace workers, even when job cuts may have little to do with the technology. Sam Altman, CEO of ChatGPT-maker OpenAI, has taken note of the pattern that he and others call "AI washing," essentially a high-tech form of whitewashing... "You know something is happening all the time when they have a word for it," said Gautam Mukunda, who teaches leadership at the Yale School of Management... AI-related employment changes are tiny so far, said Nathan Goldschlag, director of research at the Economic Innovation Group, a Washington think tank. He pointed to a recently published analysis of Census Bureau surveys, which found more than 95 percent of businesses that use AI said it hasn't changed their staff sizes — and AI-related employment increases were more common than decreases.

Long-time Slashdot reader UnknowingFool shares this report from the BBC: Air France and Airbus have been found guilty of manslaughter over a 2009 plane crash which killed 228 people. The Paris Appeals Court found the airline and aircraft manufacturer "solely and entirely responsible" for the incident, in which flight AF447 from Rio de Janeiro to Paris crashed into the Atlantic Ocean. The passenger jet stalled during a storm and plunged into the water, killing all on board. A court had previously cleared the companies in April 2023, but they were found guilty on Thursday after an eight-week trial. Both have repeatedly denied the charges and say they will appeal... The companies have been asked to pay the maximum fine — €225,000 ($261,720; £194,500) each — but some victims' families have criticised the amount as a token penalty... In 2012, French investigators found a combination of technical failure involving ice in the plane's sensors and the pilots' inability to react to the aircraft stalling led to it plunging into the sea. The captain was on a break when the co-pilots became confused by faulty air-speed readings. They then mistakenly pointed the nose of the plane upwards when it stalled, instead of down. Investigators concluded the co-pilots did not have the training to deal with the situation. Pilot training has since been improved and the speed sensors replaced.

The Free Software Foundation announced this week that "its global call for free software supporters to organize LibreLocals this May resulted in free software supporters organizing forty-six LibreLocal events on six continents thus far." (And new dates and locations are being added daily.) The FSF invited free software supporters to organize in-person community meetups in their area during May 2026, or LibreLocal month, to bring people together to swap ideas, learn from each other, and celebrate free software. People were encouraged to organize events grounded in freedom to help spread the free software philosophy.... "The success of these LibreLocals speaks to how many people globally are interested in free software and ready to build community, and it demonstrates the strength of our movement" [said FSF executive director Zoë Kooyman]. "People getting together like this also proves how computer freedom and digital rights are on people's minds. When we reject freedom-restricting software and promote software that respects user rights, it helps further so many other basic rights...." The FSF has financially supported some of the events, but notes organizers are going above and beyond to create noteworthy events by any measure, and is impressed with the global network taking shape. "The energy we feel from all organizers is extremely motivating and we look forward to seeing LibreLocal events spread even wider over the next years! We want to support these initiatives even more, so we'll be looking to build a network of sponsors for future iterations as we work towards May 2027," says Heshan de Silva-Weeramuni, FSF program manager... William Goodspeed, the organizer behind the Beijing LibreLocal, reported that their meetup was double the size of last year's, and a number of very rich collaborative projects have emerged among the attendees. Discussing the value of connecting people, de Silva-Weeramuni notes: "Free software supporters know that connecting with each other leads them to learn, experiment, and create great things that protect our individual and shared rights. The extraordinary contributions that free software has made to the world were born through such collaborations between like-minded people towards a freer society. This same global spirit of collectively building a better future is one of the inspiring things that we have once again seen unfold through this year's many LibreLocals."

On Friday TechCrunch reported they could no longer Google the word "disregard". Google's AI Overview responded "Understood. Let me know whenever you have a new prompt or question!" below an icon for hearing the word "disregard" pronounced — then displayed several inches of blank whitespace. "The Merriam-Webster link is still in there, but you have to scroll..." Earlier this week, Google rolled out a completely new Search experience, foregrounding AI summaries and kicking the traditional "10 blue links" far down the page. But the sheer scale of Google Search means there are lots of edge cases that the company doesn't seem to have considered... Google has been catching some flack on social media for this, and it's easy to see why... For most users, that single reply is the only thing you'll see. And crucially, the AI response serves no conceivable value to a user searching the word "disregard." It's just a broken tool. Google appears to have fixed the issue — sort of. Now Googling the word "disregard" brings up a list of news stories about how Google's AI Overviews misinterpreted the word disregard in search queries.

Citing new research, the Associated Press reports that "modest gains in the fight to curb climate change have dialed back the most catastrophic of future heating." That's the good news. But the same research "also confirmed that there's no chance to limit warming to the international goal set in 2015." Researchers' new list of seven plausible carbon pollution scenarios for the future are pushing aside two staples of climate policy: the extremes on either end. The extremes have become less probable in the past several years because of how we power our world. Carbon dioxide, released from the burning of gas, oil and coal, is chiefly responsible for warming. Increasing use of green energies, like solar, wind and geothermal, which don't emit carbon dioxide, have lowered top end carbon pollution projections. However, because those changes haven't been fast enough, the bottom end projections have risen. The Paris climate agreement in 2015 set a goal of limiting warming to 1.5 degrees Celsius (2.7 degrees Fahrenheit) since pre-industrial times, or the mid-1800s, giving rise to the mantra "1.5 to stay alive," but now scientists say that even their best case scenario still shoots past that signature temperature mark. On the other end, those same new scenarios no longer include the coal-heavy future that would lead to 4.5 degrees Celsius (8.1 degrees Fahrenheit) of warming by 2100, a scary scenario that many scientific studies used in their future projections. The new proposed worst case scenario has an end-of-the-century warming of about 3.5 degrees Celsius (6.3 degrees Fahrenheit), a full degree (1.8 degrees Fahrenheit) less than the old scenario, while the updated best case future is a couple tenths of a degree Celsius (0.36 degrees Fahrenheit) warmer than previously theorized, squeezing past the Paris goal, said climate scientist Detlef Van Vuuren of Utrecht University, lead author of a recent study laying out future scenarios. "There is kind of a narrowing of the futures. It cannot be as bad as we thought, but it cannot be as good as we hoped," said Johan Rockström, director of the Potsdam Institute for Climate Impact Research in Germany. The scenarios include a "middle" one where by the end of the century the world warms 3 degrees Celsius (5.4 degrees Fahrenheit) above pre-industrial times, which is roughly the path society is currently on, scientists said... Because carbon pollution keeps rising globally and stays in the atmosphere for about century, the best case scenario is for warming to shoot past the 1.5 degree mark, peak at 1.7 degrees Celsius (3.1 degrees Fahrenheit) for maybe as long as 70 years, and eventually somehow come back down below 1.5 degrees if a technology can be designed to remove massive amounts of carbon from the air, said nine of the 10 scientists interviewed for this article. The world is warming at a pace of a tenth of a degree Celsius (nearly 0.2 degrees Fahrenheit) every five years, they said.
