Nvidia Announces Vera Rubin Space-1 Chip System For Orbital AI Data Centers 147
Huang said Nvidia is working with partners on a new computer for orbital data centers, but there are still engineering hurdles to overcome. "In space, there's no convection, there's just radiation," Huang said during his GTC keynote, "and so we have to figure out how to cool these systems out in space, but we've got lots of great engineers working on it."
Are Split Spacebars the Next Big Gaming Keyboard Trend? (pcgamer.com) 58
Though for gaming, the split spacebar offers much more varied purpose. People do strange things with the WASD keys that I won't litigate here, but I'm pretty sure most gamers use their left thumb to strike the spacebar for gaming. Right? Right. If you fall into this category, you have the option of using the right-side spacebar for things like a chunky melee key, or, my personal favorite, an in-game voice chat key.
Hydropower Line From Quebec Could Power a Million NYC Homes (nytimes.com) 108
The Champlain Hudson Power Express has found a way to plug into the city, but it wasn't easy. The work included 10 new manholes and more than three miles of new underground circuitry, according to Con Edison, the city's primary electricity provider. "It was literally a hand weave under the streets of Queens," said Jennifer Laird-White, the head of external affairs for Transmission Developers. The hydropower travels from Canada via two buried cables that are as round as cantaloupes. Those lines snake for hundreds of miles under a lake, several rivers (including the Hudson for about 90 miles) and through buried trenches alongside train tracks and roads. The cables resurface in Astoria, Queens, where a converter station shapes, filters and refines the raw power into a product that New Yorkers can consume.
In two cavernous rooms that could be mistaken for "Star Wars" sets, the electricity flows through 30 hanging structures encased in what look like metallic, dinosaurlike exoskeletons. Each one weighs about as much as a small humpback whale and contains microprocessors, thousands of valves and fiber wires. "I am still wowed when I walk into that facility," said Mr. Harrison, the engineer. "I mean, it is just mind-boggling."
'Pokemon Go' Players Unknowingly Trained Delivery Robots With 30 Billion Images 57
Instead of helping users navigate the way that GPS does, VPS determines where someone is based on their surroundings. That makes Pokemon Go particularly useful as a data source, because players had to physically travel to specific locations and point their phones at various angles. That mapping effort got a significant boost in 2020, when the app added what it called "Field Research," a feature prompting players to scan real-world statues and landmarks with their cameras in exchange for in-game rewards. A portion of the data also reportedly came from areas known as "Pokemon battle arenas." Whether players knew it or not, those scans were creating 3D models of the real world that would eventually power the Niantic model. More data means better accuracy, and because Niantic was collecting images of the same locations from many different users, it could capture the same spots across varying weather conditions, lighting, angles, and heights. [...]
The idea is that Coco's robots can use VPS and four cameras mounted around the machine to get a far more precise read on their surroundings. In turn, the well-equipped robot will deliver food on time. On a broader level, Niantic says its partnership with Coco Robotics is part of a longer-term effort to build a "living map" of the world that updates as new data becomes available. Once VPS-equipped delivery robots hit the streets, they will collect even more info that can be fed back into the model to bolster its accuracy further. This kind of continuous, real-world data collection is already central to how self-driving vehicle companies like Waymo and Tesla operate, and is a large part of why that technology has improved so significantly in recent years.
Sodium-Ion Battery Tested for Grid-Scale Storage in Wisconsin (electrek.co) 135
That simpler design could make a meaningful dent in the cost of storing electricity. According to Peak Energy, its system cuts the lifetime cost of stored energy by an average of $70 per kilowatt-hour. That's roughly half the total cost of a typical battery system today. The company says it achieves those savings by removing energy-hungry cooling systems, eliminating routine maintenance requirements, and reducing the need to overbuild storage capacity to account for battery degradation over time...
If the Wisconsin pilot proves successful, it could open the door to wider adoption of sodium-ion batteries for large-scale energy storage across the US.
The UK Will Invest Billions to Build a Nuclear Fusion Industry (thetimes.com) 74
On Monday, [science minister] Vallance will also announce £180 million for a facility in Culham, Oxfordshire, to manufacture tritium fuel and £50 million for training 2,000 scientists and engineers in fusion-related disciplines. The government is also buying a £45 million fusion-dedicated AI supercomputer called Sunrise to model plasma physics. Scientists at the UK Atomic Energy Authority last year developed an AI model that can rapidly simulate how the ultra-hot fuel in a fusion power plant will behave, cutting calculations that previously took days down to seconds...
Vallance will also announce new support and collaboration for the many fusion, robotics, engineering and AI start-ups working in Britain, to develop a strong supply chain for a new fusion sector. One of those companies, Tokamak Energy, which spun out from the UK Atomic Energy Authority in 2009, has already built a smaller reactor that has informed the Step design. In March 2022, it became the first private organisation in the world to surpass 100 million degrees Celsius in its reactor.
Ask Slashdot: What's the Best All-Purpose RISC-V System on a Chip Family? 36
And "the family needs to scale — cheap and small at the low end, capable of running Linux on the bigger variants!"
Their requirements?
- WiFi + BLE required
- LoRaWAN a nice-to-have.
- Low power modes that actually work in the field, not just on the datasheet.
- Full peripheral set — SPI, I2C, UART, ADC, timers, CAN.
- A toolchain and runtime support, support multi threads...
Slashdot reader Gravis Zero is skeptical all the requirements can be met. "If you want embedded, you get embedded. If you want to run a big OS, you get one that will run a big OS."
But Slashdot reader SysEngineer believes "The obvious architecture candidates are ARM, STM, and RISC-V" — and specifically they want to hear your experiences with the RISC-V choices. "What would you standardize on today if you were starting fresh? And how does real-world toolchain and community support hold up compared to the marketing?"

Uber Co-founder Travis Kalanick's Newest Venture? 'Gainfully Employed Robots' (yahoo.com) 59
"I left Uber in 2017 heartbroken," writes Kalanick on the new company's web site. Kalanick resigned under pressure in 2017, and complains he was "torn away from an idea and a movement that I had poured my life into... I bled, but I did not perish. I got back up and fought my way back into the arena, back to my calling. Back to building. Digitizing the Physical World is my life's work... " Kalanick is remaking his real estate company, City Storage Systems, which owns ghost-kitchen operator CloudKitchens, and renaming it Atoms, according to a manifesto posted on the new company's website. [Bloomberg notes that the company's food robotics division "makes a food assembly machine called Bowl Builder, according to its website."] In addition to its work on food, Los Angeles-based Atoms is expanding into robotics technology for mining and automotive transport. Kalanick said on the livestreamed tech talk show TBPN Friday that Atoms has effectively been in stealth for eight years and has "thousands" of employees....
Kalanick wrote on the Atoms website that the company will make "specialized robots with productive jobs that bring abundance to their owners and society at large." That will include "infrastructure for better food," he wrote, as well as "more productive mines to power Earth's industries" in addition to "wheelbase for robots" in transportation. "The industrial thing is probably our main jam," he said on TBPN. "Once you crack movement in the physical world, there are lots of people who want access to that..." Kalanick also said he was the biggest investor in Pronto, a self-driving trucking startup that currently focuses on closed sites like mines.
America's First Large-Scale Offshore Wind Project Finally Finishes Construction (wbur.org) 71
But it took a while... The plant's first construction delay happened back in 2019, they point out — and then "Just three months ago, when the project was 95% complete, the U.S. Interior Department issued a stop-work order." But after successfully challenging that order in court, and "with a stretch of good weather offshore, the developers behind the $4.5 billion project managed to get over the finish line."
The Associated Press notes it was "one of five major East Coast offshore wind projects the Trump administration halted construction on days before Christmas, citing national security concerns." Developers and states sued, and federal judges allowed all five to resume construction, essentially concluding that the government did not show that the national security risk was so imminent that construction must halt. Another one of the five, Revolution Wind, began sending power for the first time to New England's electric grid on Friday and will scale up in the weeks ahead until it is fully operational.
"That project is nearly complete as well," notes WBUR, "and will eventually be capable of powering up to 350,000 homes."
Are U.S. Utilities Trying to Delay Easy-to-Use Solar 'Balcony' Panels? (npr.org) 120
But what's holding up their adoption in America? For the panels to become more widely available in the U.S., state lawmakers are proposing bills that eliminate complicated utility connection agreements, which are required for larger rooftop solar installations and, most utilities say, should apply to plug-in solar too. Those agreements, along with permitting and other installation costs, can double the price of solar panels. Utah enacted the first law, last May, supporting plug-in solar, and now some 30 pieces of similar legislation have been introduced around the United States. [And Virginia seems poised to pass a similar law.]
But the drive toward plug-in solar is facing pushback from electric utilities. They are raising safety concerns and prompting legislators to delay votes on the bills. So far, utilities have won over lawmakers in five states and convinced them to delay votes on plug-in solar bills... Plug-in solar advocates say that safety concerns about the new technology have been addressed and that utilities are really just worried about losing business, because every kilowatt-hour generated by a plug-in solar panel is one less the utility sells to a customer... There are safety risks with any electrical appliance, and it's true that plug-in solar panels present some unique problems. But safety experts also say those issues can be managed....
German utilities expressed many of the same concerns nearly a decade ago when plug-in solar started to become popular in Germany. But with more than a million systems installed, no safety incidents have been reported for customers who used the panels as instructed, according to a research paper funded by the U.S. Department of Energy.
Gaming Site Editor Jailbreaks an Amazon Echo Show (aftermath.site) 10
Not only can the hacked Echo Show 8 control my entire smart home, it now plays back my entire local music library as well as any internet radio channels like The Lot Radio and NTS. It can also synchronize with any additional Echo Show running LineageOS in my house using the SendSpin protocol... I would gladly take it any day of the week over most of the devices these companies offer, especially Amazon. It may not be as intuitive as out-of-the-box smart home products, but I don't need my devices to be intuitive, I need them to behave. I had finally found a smart display that wasn't a cop...
The hardware is old and creaky, and after the hack it can only use 1GB of the 2GB of ram. And yet it still manages to feel snappier than the stock hardware. "The amount of telemetry, ads, and general bloat Amazon shoves down our throats definitely doesn't help performance," [XDA Devs Forum user] Rortiz2 told me. "That's actually another reason why we did LineageOS, it kind of gives the device a second life. Even though it's still a bit buggy, it feels way better to use than the stock firmware...." If you want a smart speaker with a display that just runs a stripped-down version of Android that you have full control over, you're going to have a hard time finding it outside of these three specific models unless you cobble something together yourself. It is a deceptively simple thing to desire — the kiosk computer from science fiction that isn't a narc — yet few companies really offer it.
"It should be against the law to not give an end user the ability to consensually load whatever OS or program they want on their device..." the article concludes, arguing that "If we budge on the inalienable right to modify our hardware then we forsake a key part about what makes computers special."
And in the mean time, "There are so many devices that could be put to use rotting in e-waste facilities and thrift stores..."
Should Keycaps Use Text or Glyphs for Delete, Return, Tab, Caps Lock, and Shift? (macrumors.com) 76
"Apple already uses glyph-based key labels on several European keyboard layouts," notes The Mac Observer, "including British English versions of the MacBook. Because of this, the design will feel familiar to many users outside the United States."
The change was noticed last week by Chicago-based X.com/YouTube user "Mr. Macintosh", who makes how-to videos about now and old Macs.
Backblaze Hosts 314 Trillion Digits of Pi Online (nerds.xyz) 67
Here's what StorageReview founder Brian Beeler said about the project: "Pushing [Pi] to 314 trillion digits was far more than a headline number. It was a sustained, months-long computational challenge that stressed every layer of modern infrastructure, from high core-count CPUs to massive high-speed storage, and it gave us valuable insight into how extreme, real-world workloads behave at scale. Making this dataset available in the Backblaze cloud takes the project a step further by opening access to one of the largest raw outputs ever generated in a single-system calculation. Hosting multi-petabyte files for the broader community is no small feat, and we appreciate Backblaze stepping up to ensure researchers, developers, and enthusiasts can explore and build on this record-setting achievement."
Apple MacBook Neo Beats Every Single x86 PC CPU For Single-Core Performance (notebookcheck.net) 329
Strait of Hormuz Closure Triggers Work From Home, 4-Day Weeks In Asia (fortune.com) 114
Vietnam also called on businesses to let people work-from-home to "reduce the need for travel and transportation." The Philippines is pushing for a four-day work week, and has ordered officials to limit travel "to essential functions only."
South Asia is getting hit hard too. Bangladesh brought forward the Eid-al-fitr holiday, allowing universities to close early in a bid to save fuel. Pakistan also instituted a four-day week for government offices and closed schools. India suspended shipments of liquefied petroleum gas to commercial operators to prioritize supplies for households, leading to worries from hotels and restaurants that they may be forced to close without fuel supplies. Countries across the region are also considering price caps, subsidies, and tapping strategic oil reserves. On Wednesday, the International Energy Agency "unanimously" agreed to release 400 million barrels of oil and refined products from its reserves.
The Associated Press offers a look at the energy supplies that countries hold and when they tap them.

ASUS Executive Says MacBook Neo is 'Shock' to PC Industry (pcmag.com) 226
He also described the MacBook Neo as a "content consumption" device, similar to an iPad. "This is different from the use case of a mainstream notebook," which can handle more compute-intensive tasks, Hsu said. "How big of an impact [the MacBook Neo] will have on the PC industry will still require some time for us to observe," Hsu said while suggesting it might not gain traction among Windows PC users due to software differences. "Of course, the entire Windows PC ecosystem will push out products to compete against Apple," he added.
Intel Demos Chip To Compute With Encrypted Data (ieee.org) 37
Startups are racing to beat Intel and each other to commercialization. But Sanu Mathew, who leads security circuits research at Intel, believes the CPU giant has a big lead, because its chip can do more computing than any other FHE accelerator yet built. "Heracles is the first hardware that works at scale," he says. The scale is measurable both physically and in compute performance. While other FHE research chips have been in the range of 10 square millimeters or less, Heracles is about 20 times that size and is built using Intel's most advanced, 3-nanometer FinFET technology. And it's flanked inside a liquid-cooled package by two 24-gigabyte high-bandwidth memory chips—a configuration usually seen only in GPUs for training AI.
In terms of scaling compute performance, Heracles showed muscle in live demonstrations at ISSCC. At its heart the demo was a simple private query to a secure server. It simulated a request by a voter to make sure that her ballot had been registered correctly. The state, in this case, has an encrypted database of voters and their votes. To maintain her privacy, the voter would not want to have her ballot information decrypted at any point; so using FHE, she encrypts her ID and vote and sends it to the government database. There, without decrypting it, the system determines if it is a match and returns an encrypted answer, which she then decrypts on her side. On an Intel Xeon server CPU, the process took 15 milliseconds. Heracles did it in 14 microseconds. While that difference isn't something a single human would notice, verifying 100 million voter ballots adds up to more than 17 days of CPU work versus a mere 23 minutes on Heracles.
Samsung Wants To Let You Vibe Code Your Galaxy Phone Experience 34
Samsung recently debuted the Galaxy S26 series of phones and made a point to not call them smartphones -- they're "AI phones" now. This certainly rang true with the majority of upgrades to the devices being AI software-focused, like the new Now Nudge and expanded Audio Eraser tools, with the biggest hardware bump for the base models coming via the 39% improved NPU processing (the processor in charge of on-device AI tasks). It also teased the debut of Perplexity on its phones, joining as an alternative to the Gemini assistant, and teased the possibility of other AI models getting the same treatment in the future.
