Targeting students and beginners, Adafruit released "CircuitPython" in 2017 (as a derivative of the MicroPython microcontroller-optimized programming language).

Now Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone) brings this update: Adafruit has published CircuitPython Turbo, a workflow that compiles selected Python functions into native machine code on a computer, then loads them onto compatible microcontroller boards.

It builds on MicroPython's Native and Viper emitters. In a documented Metro RP2040 fixed-point Mandelbrot test, Viper cut computation time from 8.335 seconds to 0.423 seconds, a 19.71x speedup over bytecode. The rest of the application stays in Python. The guide includes benchmarks, source code and hardware demos. The speedup is for the measured computation, not the whole application.
"Turbo support is now included in the latest official CircuitPython builds for RP2040 and RP2350 boards..." explains Torrone's announcement at Adafruit.com. "The new Turbo in CircuitPython helps when the board spends time calculating: making neopixel effects, drawing fractals, processing audio, filtering sensor readings, or preparing lots of pixels. Those projects can get smoother animation, quicker responses, or room to do more things at once." With Turbo, it's easier, better, and now even faster to make LED light up costumes that also reacts to sound at the same time, a sensor dashboard with animated graphics, or a tiny game doing physics while drawing the screen. Turbo speeds up the busy Python parts. It won't make a slow sensor or display connection faster... Your computer turns selected functions into instructions the chip can run directly. Python still handles the rest.

We have measured speedups, real display captures, and examples you can pull apart to see what happened. None of this arrived alone. CircuitPython, MicroPython, PyMCU, compiler tools, open hardware, and people sharing their work gave us pieces to connect. The Bao experiments take that idea somewhere else, handing calculations to four helper cores. Now we get to make those paths easier to use, compare results, and find the next useful thing. Maybe that's smoother animation, a responsive instrument, or an idea we haven't tried yet.

That's what I like about open source. Someone shares a piece, someone else sees a possibility, and we get to keep building it together.

"As parts of the Southern California coastline crumbled into the sea, slammed by intense waves and flooding in recent days, oceanographer Kim McCoy had one thing on his mind," reports the Los Angeles Times.

He was thinking about "the nuclear waste set in concrete on the beach near San Clemente at the shuttered San Onofre nuclear power plant." "Rising sea levels, storm waves, El Niño which increases wave height ... these could wash away a section of the walkway that protects the San Onofre seawall, and the waste canisters are just 100 feet away from that," the former wave dynamics researcher and longtime advocate against beach storage of nuclear waste said. Most experts agree the risk of erosion damaging the nuclear waste storage system is extremely low in the near term. The plant's owner, Southern California Edison, has promised the California Coastal Commission to move the waste to higher elevation on-site if modeling shows sea level rise and erosion will start to pose a challenge. But the recent waves, fueled by Hurricane Marie far away in the Pacific, resurfaced the issue of the ultimate fate of the highly radioactive spent fuel that used to power the reactors. "At the moment, it is under control, I think it's essential to say that," said James Day, a geology professor at UC San Diego. "But geologically we must be thinking long term. The waste lasts for hundreds, if not thousands of generations...." [In 2103 some of the site's canisters' approach their intended 100-year lifespans, and the utility may have to start the transfer into new cansiters.]

The distinctive twin domes that once housed the reactor cores will start coming down early next year. But the 3.6 million pounds of high-level waste will stay in the coastal community indefinitely. How much of a safety hazard that is depends on whom you ask. "San Onofre is sitting on some fairly young rocks in a seismically active region," Day said at a recent symposium at the Scripps Seaside Forum in La Jolla, hosted by the Samuel Lawrence Foundation. "This is not the sort of place you would leave nuclear waste." Others noted that collapse of beach slopes could make the site more vulnerable to tsunamis. They spoke of the corrosive effects of the ocean air on the steel canisters that hold the waste...

Edison says its system will be safe for decades to come. "The maximum credible tsunami here would not even overtake the seawall," said Manuel Camargo, principal manager of decommissioning for Edison, standing on the concrete pad that holds the steel waste storage canisters. "The maximum credible earthquake, somewhere around a 7.0 magnitude, would produce something about half of what this system is designed to withstand...." Edison is bolstering a path below the seawall. Based on state data from the California Ocean Protection Council, the seawall would not be inundated before 2050, Camargo said...

Plans for a deep geological repository beneath Yucca Mountain in Nevada crumbled in the face of local opposition in 2011. Utilities around the U.S. now sue the federal government every year to recoup their storage expenses because the Department of Energy has not come through on its promise. The lawsuits cost taxpayers $2 million a day, according to Camargo. "It's so safe that it's almost a problem," Camargo said. "It's not a priority to a lot of folks to move it."
"The Trump administration's Department of Energy wants to create 'campuses' in several states to store waste," the article points out, "and, in exchange, give local jurisdictions funding to develop different aspects of the nuclear cycle — such as fuel creation, power generation and potentially fuel recycling..."

"The administration wants to address the fact that waste is sitting at 80 reactor sites around the country. It also needs places for waste from new reactors it wants to build."

"Californians just made it through the hottest August on record without having to endure any rolling power outages," reports the Los Angeles Times. In fact, the state hasn't implemented rotating power outages since 2020.

Because "Over the last few years, California has quietly but dramatically increased the resiliency of its electrical grid through a significant expansion in battery energy storage." These batteries hold onto solar energy captured during the day, so it can be sent to the grid as demand peaks in the evening and morning, when most people are at home running air conditioners and other appliances.

During the August heat wave of 2020, the California Independent System Operator, which manages the flow of electricity for most of the state, declared a Stage 3 Emergency and hundreds of thousands of households lost power in rolling outages. At the time, the system had less than 100 megawatts of battery storage available, according to system spokesperson Jayme Ackemann. Today, it has more than 17,000 megawatts available....

According to Ackemann, the system seeks to add 20,000 to 25,000 megawatts of battery storage capacity by 2045 — the same year it has set a goal of achieving carbon neutrality. That means the state would remove as many carbon emissions from the atmosphere as it emits.

In recent years, California has steadily grown the share of electrical power generated by renewable sources — such as solar, wind, geothermal and hydropower — which bolstered the resiliency of the grid by increasing the overall amount of energy available. An uptick in people installing rooftop solar panels has provided an additional power boost, Ackemann said. In May, California became the first known large-scale power system in the world to have relied on more than 50% solar power for an entire month.... California's grid is also now integrated with electrical systems across much of the Western United States. This means that if there is an extreme heat event in Southern California, energy from a cooler area such as the Pacific Northwest can be imported to help meet regional demand. All of this has collectively helped the state's electrical system weather this year's long-lasting heat.
"Southern California continued to break temperature records this week when Long Beach and Anaheim reached a blistering 107 degrees and Escondido hit 112 degrees..."

An anonymous reader quotes a report from Wired: Apple has unveiled the Apple Watch Series 12 and Ultra 4 today during itsSeptember hardware event. The new models retain the signature designs of their predecessors but add a faster S11 chip, new health and fitness features, and the watchOS 27 software update announced atWWDC last June. Both the Series 12 and Ultra 4 run on the upgraded S11 chip, which Apple says delivers faster CPU and GPU performance, along with improved Siri capabilities. Apple is also expanding the smartwatch's wellness-tracking suite with a redesigned Health app that includes a Longevity tab with new metrics, like Health Age and a Readiness score.

There's also a new "Health Sensing System," designed with 32 electrodes for more accurate readings (the Series 11 only had two), photodiodes organized in a ring to capture light more efficiently, and new LEDs that allow heart rate measurements to be collected every 5 seconds, giving you a continuous stream of heart data throughout the day. Apple Watch Series 12 also includes faster charging, though battery life remains at 24 hours. Meanwhile, the Ultra 4 increases battery life to 50 hours.

WatchOS 27 also brings deeper Siri and Apple Intelligence integration, including AI-suggested apps, new one-handed gestures, expanded workout and women's health tracking, and Siri Recap for real-time transcription and translation.

Google plans to invest at least $15 billion in AI infrastructure in Finland through 2028, its largest single investment in Europe. The company also signed a 22-year power agreement with Finnish utility Fortum and said it will explore business models that could support new nuclear reactors at Fortum's Loviisa site.

Finland has emerged as a major data-center hub thanks to its available land and power. "I've heard it called the 'Texas of Europe' at industry events," Matti Lajunen, partner of real estate at Finnish law firm Hannes Snellman, told CNBC. "What we're now seeing is weekly new inquiries for market entry into Finland from new players."

Ruth Porat, president and chief investment officer of Alphabet and Google, said in a statement: "Google is proud to deepen our roots in Finland with the company's largest single investment in Europe, building on more than 15 years of sustained investment in Finland. This investment underscores Google's commitment to grow our presence responsibly, pairing the expansion of our technical infrastructure with new energy capacity, grid enhancements, and energy affordability initiatives."

Apple's iPhone 18 Pro and Pro Max were announced today and keep last year's overall design but put the emphasis on camera upgrades, including a 48-megapixel variable-aperture system, new manual controls, and 4K Dolby Vision recording. Prices for the devices start at $1,199 and $1,299, respectively. TechCrunch reports: The new Pro series camera features a 48-megapixel camera with variable aperture, made with six thin blades. This system will likely improve low-light photography quality and speed. There are also new pro controls in the camera software, including white balance, shutter speed, aperture and histogram. There are also new photographic styles with texture and grain controls. [...]

The new camera can record 4K videos in Dolby HDR Vision, and also apply cinematic effects after shooting the footage. The new Pro devices also have a smaller dynamic range island on the front of the device, which now allows you to track three live activities instead of two.

Both phones are powered by Apple's latest A20 Pro silicon and feature a newly designed vapor chamber for improved cooling. The company has also improved the battery with a better design. Apple also said the iPhone 18 Pro supports video playback of 36 hours, and the 18 Pro Max has 45 hours of playback capacity. Apple Unveils the iPhone Duo, Its First Foldable iPhone

An anonymous reader quotes a report from Ars Technica: Those who remember PC gaming in the days before Steam may have fond memories of the "big box" packaging that made those games stand out as shelf eye candy and sought-after in-home collectibles. Today, PC gaming platform GOG is hoping to reignite some of the nostalgia for those days by adding downloadable 3D models and printable, foldable high-res packaging scans for a handful of PC games on the platform.

Thus far, the "Printable Big Box" collection on GOG is limited to just five games: Armikrog, Descent, Hitman: Codename 47, Myst, and Star Trek: 25th Anniversary. Players browsing those games on the GOG store will now see "3D Boxes" listed among the included "Goodies" before purchase. Owners of those games on GOG can download a ZIP file containing a version of the box art as an animated 3D object file (in an easy-to-open GLB format) and a "flat printable template" in PDF, SVG, and Adobe Illustrator formats. Those downloads allow for what GOG calls "a proper papercraft project for anyone who misses shelves full of PC game boxes."

The physically focused expansion of the existing GOG Preservation Program comes through a partnership with Benjamin Wimmer's Big Box Collection website, which has grown since 2015 to include over 1,000 3D scans from his private collection of physical PC games. In an interview with GOG, Wimmer said that while he appreciates the artistry of a good old-fashioned big box, he also appreciates their evolution into the "interactive cards" on modern digital storefronts that "provid[e] us art, screenshots, gameplay videos and whatnot and that not shown as a box, [it] is just good UX." "Physical media doesn't survive the way software can -- boxes get lost, crushed, thrown out," GOG writes in today's announcement. "Scanning them, and letting you print your own, is preservation in a different shape: the same mission that keeps these games running on modern PCs, applied to the objects they used to come in."

The U.S. Department of Energy has approved a $1.9 billion loan to NextEra Energy to restart Iowa's shuttered Duane Arnold nuclear plant, which Google has backed as a power source for its growing AI infrastructure. "The sizable loan is the second of its kind, suggesting that the Trump administration views revived nuclear power as a key source of electricity for tech companies seeking to power their AI data centers," notes TechCrunch. From the report: James Danly, Deputy Secretary of Energy, said that the Iowa power plant's restart in 2029 will "drive down electricity costs," though he did not explain how. Just 50 megawatts will be set aside for the local power cooperative, NextEra CEO John Ketchum said during an earnings call (PDF) last year. That capacity would cover 18% of Iowa's demand growth since 2021, the year before ChatGPT was released.

Google is reportedly looking to build up to six data centers near the Duane Arnold Energy Center, which hasn't operated since 2020 when an intense rainstorm damaged the power plant. Rather than repair it, NextEra decided to mothball it. At the time, cheap natural gas was flooding the market, making nuclear power economically unappealing. A lot has changed in the last six years, though. After decades of little growth in demand, the sudden rise of AI coupled with broader electrification of the economy meant that utilities and power providers were suddenly scrambling to find new generating sources of electricity. New data centers are expected to nearly triple the sector's electricity demand by 2035.

The EV blog Electrek reports: A Clinton Township, Michigan man was charged $418 for a single EV charging session at Elder Hyundai's Macomb Township store after finding the charger listed as publicly available on the EVgo app, but didn't discover the charges until after wrapping up his 40-ish minute charging session. "I was flabbergasted," explained Stanley Kpenkann, who had been driving a rented Chevy Bolt EV at the time. "Never in my wildest dreams did I think I would be saddled with a bill of $418 for a charging session."

After calling EVgo to report the error, he found that the exorbitant charge wasn't a mistake at all - Elder Hyundai was charging customers an eye-gouging $5 per kWh, plus another $5 for every minute connected.
A local news report notes that "After back-and-forth with EVgo, the company processed what it called a goodwill refund of $405." (And the dealership argued their charger was reserved for its own customers and vehicles, so they set prices high to deter outside use.)

But Electrek argues the story "speaks to much larger problems among the EV charging business in particular and car dealerships in general..." [In June] Plug & Play EV's Steve Birkett took to LinkedIn to call out his local Hyundai dealer in Union, NJ for charging a ridiculous $15 per kWh to top off his IONIQ 5 (!)... Even worse, he noted that a number of area dealerships that had listed their ports as "public" were actively discouraging public use with signs and stickers designed to turn people away...

[U]nlike gas stations, EV charge point operators in many states aren't required to clearly advertise what they'll charge before a driver plugs in in the same way that gas stations are: with clearly legible signage that's visible from the street.

A new study published Friday in AGU Advances "depicts the most advanced picture yet of how a rare but massive solar storm could affect some US industries and electric systems more than others," reports CNN.

"During a 250-year solar storm, the East Coast would have widespread potential for grid failure." Researchers modeled what a Carrington Event — a 1-in-150-year geomagnetic storm or even rarer — could mean for the modern day. They estimate the US economy would lose about $1.5 billion to $2 billion per day from direct and indirect costs, as millions of people face power outages. The findings show the most vulnerable areas are the Northeast and the Northern Plains, especially locations at higher latitudes.

No one knows when the next big storm will hit. While the most severe geomagnetic storms are labeled as once-in-a-century or rarer, these events don't follow a fixed schedule. "That timing only averages out on very long timescales," said Anna Kelbert, a geophysicist at the Harvard-Smithsonian Center for Astrophysics, who was not involved in the study but previously studied solar storm effects on power grids. "The event can occur at any time, as soon as a week from now, or centuries later...." [Shawn Dahl, service coordinator at the Space Weather Prediction Center operated by the National Oceanic and Atmospheric Administration in Boulder, Colorado], said the sun is now coming down from a period of heightened activity, which is also when some of the biggest storms to hit Earth have occurred in the past. "We still need a lot of work to be ready...."

"We haven't really seen events like this size in the modern era, where we've had all of this high technology and we've had the power grid of this size," said Ed Oughton, researcher at George Mason University and lead author of the new study... Because the US grid's actual structure is proprietary for security reasons, the team used engineering models to create various network and transformer setups including the 10,464 substations and 16,256 transmission lines found across the country... The grid structure also contributes to higher risk in some areas. For instance, the eastern US is linked together in a single grid interconnection. A voltage issue in Maine, if not isolated early, could cascade through the grid to Washington, DC. The West works similarly, whereas the Texas interconnection operates mostly within the state...

Power is restored over time depending on any alternative electrical paths that could bypass the substation or availabilities of spare transformers, for instance. "This nationwide analysis shows that we are currently ill-prepared to face a major magnetic storm, and that the societal impacts would be catastrophic," Kelbert said.
"The study estimates power disruptions for 5.1 million people and 135,000 businesses," according to the article, and "The outages could last from hours to days to weeks depending on the damage and resources available to get back online, said Oughton."

John Ternus has officially taken over as Apple CEO after 15 years under Tim Cook, stepping up from his role as senior vice president of hardware engineering. A 25-year Apple veteran who helped oversee products including AirPods, Apple Watch, Vision Pro, Apple silicon, and the new MacBook Neo, Ternus now inherits the challenge of pushing Apple forward in AI while Cook stays on as executive chairman. TechCrunch reports: Ternus has worked at Apple for nearly half of his life -- now 51 years old, he has been with the company for 25 years. He joined Apple's product design team in 2001 as only his second job out of college (his first was at a small maker of virtual-reality devices called Virtual Research Systems). By 2013, Ternus was a VP of hardware engineering and was promoted to the SVP role in 2021. [...] Ternus previously reported to Cook, who he considers a mentor, and led all of hardware engineering at Apple. That's a pretty big deal for a company that's known for ubiquitous hardware like the iPhone and the MacBook. [...] Ternus' earliest project at Apple involved scrutinizing parts for the Apple Cinema Display, an early desktop monitor. "At some point in my first year, I found myself at a supplier facility. I was far away from home. Well past midnight, I was using a magnifying glass to count the number of grooves on the head of a screw ... and I was arguing with the supplier because these parts had 35 grooves. They were supposed to have 25," Ternus recalled in his commencement speech. "I distinctly remember stepping back for a minute and thinking, 'What the hell am I doing? Is this normal?'"

As Ternus climbed the corporate ladder, his responsibilities grew. He may no longer spend as much time analyzing screws, but he still seems to take pride in getting the little details right. In a recent interview, when Ternus was asked about his favorite memory of Steve Jobs, he mentioned the former Apple co-founder's attention to craftsmanship. "[Jobs] was moving a piece of furniture, a chest of drawers, and pulled it away from the wall and looked at the back and was just reflecting on, you know, that the carpenter who made it had made it beautiful," Ternus said. "It finished the back as beautifully as the rest of it, even though nobody was going to see it, right? And I think about that all the time because I think that perfectly exemplifies what we do here."

From there, he went on to lead the hardware development behind products across the Apple ecosystem, overseeing launches like AirPods, Apple Watch, and the Vision Pro. He also had a hand in major technical upgrades at Apple, like Apple's transition from Intel chips to its own proprietary Apple silicon. Most recently, Ternus was involved in the production of the MacBook Neo, Apple's new, more affordable laptop model that lowers costs through some clever trade-offs in hardware design, like using an iPhone chip to power the device. "We never want to ship junk. We want to ship great products that have that Apple experience, that Apple quality. To do that with the Neo required building something completely new from the ground up ... leveraging both the technologies we'd been developing like Apple silicon, but also the kind of expertise that we've developed over many, many years of building Macs, and building phones, and building iPads, and all of these things," Ternus told Tom's Guide.

California lawmakers have passed a bill that would legalize plug-in "balcony" solar systems, allowing residents to connect small solar panels directly to a standard wall outlet after completing a simple online registration. The systems would be capped at 1,200 watts and must meet safety requirements designed to prevent power from feeding back onto the grid during outages. KQED reports: The legislation, SB 868, sailed through the state assembly and senate with bipartisan support. The bill now moves to the governor's desk for signature. The devices can be tented in a backyard, hung off a balcony or placed on a roof. Models range from as low as $300 to $2200, depending on size. The bill would open the solar market to people who were previously left out: renters, people with unsuitable roofs, and those lacking the capital to build out a rooftop system, which can cost in the tens of thousands of dollars.

[...] If signed into law by Newsom, the legislation would exempt plug-in solar devices from what critics say is a cumbersome and expensive interconnection application process, and replace registration with a free and straightforward online form. [...] The newly passed bill outlines several device requirements. The balcony solar systems must be capped at generating 1,200 watts per home, plug into a standard outlet, offset a customer's onsite electricity use and meet state and national electrical codes. They also must be certified by an outside safety organization like Underwriters Laboratories and have a feature that would prevent electricity from feeding back into the grid if there's a power outage.

According to The Information (paywalled), Apple reportedly moved up the release of new Mac mini and Mac Studio models after unexpectedly strong enterprise demand for Macs capable of running AI workloads. MacRumors reports: Apple normally releases new Mac models in the autumn, closer to October or November, making this week's announcement unusually early, falling just before the anticipated arrival of new iPhone models. The Information says that the AI-driven boom in Mac Studio and Mac mini sales is behind the early launch. Apple noticeably promoted the ability to link multiple Mac Studios together into a single, more capable system for running large frontier AI models, a feature aimed at business and developer customers rather than everyday consumers.

Apple highlighted the Mac mini and Mac Studio's shift toward business buyers in June, with a "Business at the Park" event involving executives from major companies Ford, Disney, and Anthropic. The Mac mini was said to be the "darling" of the event. Even so, enterprise's rush toward powerful desktop Macs more broadly took Apple by surprise.

The company reportedly did not possess an engineering team dedicated to business customers or staff focused on developer relations, and lacked an enterprise AI strategy. Businesses that approached Apple asking to buy access to the company's Private Cloud Compute infrastructure were reportedly turned down. Apple is instead leaning on partners such as WebAI and Mount Thor, which provide AI tools and execution environments built on Apple hardware.

The Washington Post shares this tip for car buyers.

Electric vehicles "are not driving the recent growth in recalls warning that vehicles could erupt into flames at any time, even when parked and turned off." A Washington Post analysis of National Highway Traffic Safety Administration (NHTSA) recall notices found that conventional gas and diesel vehicles made up the vast majority of vehicles covered by the "park outside" label since 2021.

Last week, The Post wrote about an alarming surge in these so-called "park outside" recalls... A total of an estimated 3.4 million vehicles currently have outstanding recalls of this kind, according to vehicle history provider CarFax. Safety experts say the surge in "park outside" recalls appears to be caused by other changes to modern gas and electric vehicles, such as the additional technology in everything from transmissions to seat warmers.... [It's a messy mix of things that "doesn't lend itself to simple description of what's happening," says Sean Kane, president of auto safety-analysis firm Safety Research and Strategies. "But it boils down to growing electronic systems and the number of components."]

They're known as "key-off fires," said Frank Borris, a former NHTSA investigator who now works as a safety consultant. "The engine is off," he said, "but the circuits are still hot and they stay hot all the time." Earlier this year, Kia needed to recall 463,000 Tellurides because of the risk that the front power-seat switch could overheat and ignite the seat. That was the second time Kia had issued a recall for that one defect. The first recall, in 2024, didn't fully address the problem. More than 66,000 Ford Expeditions and Lincoln Navigators from the 2021 model year were recalled due to circuit boards in the battery junction box that could short out. At least 16 fires were blamed on the problem, which often ignited when the vehicles were parked and turned off.

NHTSA has issued 93 "park outside" recalls since 2021, according to a Post analysis. Nearly half — 44 recalls — covered vehicles exclusively with conventional internal-combustion engines, while 38 recalls were just for EVs or hybrids. So the number of campaigns were nearly equally divided between gas and electric or hybrid vehicles. But gas vehicles pull away when comparing the size of the recalls. Gas-only campaigns covered a combined 4.6 million vehicles with "park outside" recalls over the past five years, compared to only about 662,000 vehicles that were EVs or hybrids...

Other countries have provided limited looks at the EV fire issue, such as an United Kingdom government review of data from Norway finding that gas and diesel vehicles had a fire incidence rate that was four times higher than EVs from 2016 to 2021.
Just in 2026, U.S. authorities have announced 17 new "park outside" recalls covering 1.7 million vehicles, according to the article.

Longtime Slashdot reader dhartshorn writes: Foreign-produced "bulk power" equipment is now effectively banned, and the list of what constitutes such equipment is essentially everything used to make up the grid... much of which we are heavily dependent on foreign sources to supply. In a Wednesday executive order, President Trump said foreign supply of electric equipment "constitutes an unusual and extraordinary threat" to national security. The Hill reports: Under the order, it will be up to Energy Secretary Chris Wright, in coordination with other officials, to determine whether a piece of equipment poses an issue. The order could impact a wide range of equipment, including substations, transformers, batteries used for energy storage, generators, turbines, software and more. It does not lay out specific threats or single out any country by name.

[...] Under the last Trump administration, the president put a similar order in place. The new order comes amid several reported cyberattacks on U.S. water systems, which officials suspect have links to Iran, according to The New York Times.
