An anonymous reader quotes a report from the Wall Street Journal: Rivian is joining with Redwood Materials to reuse EV batteries for energy storage -- the largest repurposed-battery energy storage system for an automotive manufacturer in the U.S., executives told The Wall Street Journal. Redwood Materials is a battery-recycling firm started by Tesla co-founder JB Straubel. Once completed later this year, Rivian's plant in Normal, Ill., will draw electricity from more than 100 Rivian EV batteries in an area the size of a small parking lot. It will reduce Rivian's dependence on the power grid during peak demand hours. "It saves Rivian money on what it takes to run the plant. It reduces the demand on the grid, which is great," Rivian Chief Executive Officer RJ Scaringe said in an interview.

In the Rivian project, the batteries will come from either its test vehicles or from vehicles that have viable batteries but can no longer drive. Those batteries get sent off to Redwood, which integrates them into power storage units. Both companies declined to specify the cost of this project. The setup is expected to initially provide 10 megawatt-hours of energy, equivalent to about 1,000 home-energy battery storage units linked together, Redwood's Straubel said. "These batteries are already built," he said. "We need to integrate them and connect them together, but that can happen quite fast. They don't have to get imported from some other place." [...] Scaringe said that while branching into battery energy storage systems is "not a focus for us as a business right now," Rivian hopes to do more at its sites with Redwood. "There's hopefully a lot more, and there's going to be a lot of batteries we'll have access to," he said.

Microsoft has sharply raised prices across its Surface lineup as RAM and component costs keep climbing. "Both its midrange and flagship Surface lines are now significantly more expensive than they were just a few weeks ago, with the flagship Surface Laptop 7 and Surface Pro 11 now starting at $500 more than they launched at in 2024," reports Windows Central. From the report: The Surface Pro 12-inch, which was previously Microsoft's cheapest modern Surface PC at $799, now starts at $1,049. The flagship Surface Pro 13-inch, which originally launched for $999, now starts at an eyewatering $1,499. It's the same story for the Surface Laptop lines, with the entry-level 13-inch model originally priced at $899, now starting at $1,149. The 13.8-inch flagship Surface Laptop launched at $999, but now costs $1,499, with the 15-inch model now starting at $1,599. This means that Microsoft's midrange devices now cost more than the flagships did when they launched in 2024.

[...] Microsoft has raised prices for all SKUs on offer, meaning the high end models are now more expensive too. A top end Surface Laptop 15-inch with Snapdragon X Elite, 64GB RAM and 1TB SSD storage now costs a staggering $3,649. To compare, the 16-inch MacBook Pro with an M5 Pro, 64GB RAM, and 1TB SSD is $3,299, and that comes with a significantly better display and much more power under the hood.

A proposed California bill would require 3D printer makers to use state-certified software to detect and block files for gun parts, but advocates at the Electronic Frontier Foundation (EFF) say it would be easy to evade and could lead to widespread surveillance of users' printing activity. The Register reports: The bill in question is AB 2047, the scope of which, on paper, appears strict. The primary goal is clear and simple: to require 3D printer manufacturers to use a state-certified algorithm that checks digital design files for firearm components and blocks print jobs that would produce prohibited parts. [...] Cliff Braun and Rory Mir, who respectively work in policy and tech community engagement at the EFF, claim that the proposals in California are technically infeasible and in practice will lead to consumer surveillance.

In a series of blog posts published this month, the pair argued that print-blocking technology -- proposals for which have also surfaced in states including New York and Washington - cannot work for a range of technical reasons. They argued that because 3D printers and other types of computer numerical control (CNC) machines are fairly simple, with much of their brains coming from the computer-aided manufacturing (CAM) software -- or slicer software -- to which they are linked, the bill would establish legal and illegal software. Proprietary software will likely become the de facto option, leaving open source alternatives to rot.

"Under these proposed laws, manufacturers of consumer 3D printers must ensure their printers only work with their software, and implement firearm detection algorithms on either the printer itself or in a slicer software," wrote Braun earlier this month. "These algorithms must detect firearm files using a maintained database of existing models. Vendors of printers must then verify that printers are on the allow-list maintained by the state before they can offer them for sale. Owners of printers will be guilty of a crime if they circumvent these intrusive scanning procedures or load alternative software, which they might do because their printer manufacturer ends support."

Braun also argued that it would be trivial for anyone who uses 3D printers to make small tweaks to either the visual models of firearms parts, or the machine instructions (G-code) generated from those models, to evade detection. Mir further argued that the bill offers no guardrails to keep this "constantly expanding blacklist" limited to firearm-related designs. In his view, there is a clear risk that this approach will creep into other forms of alleged unlawful activity, such as copyright infringement. [...] Braun and Mir have a list of other arguments against the bill. They say the algorithms are more than likely to lead to false positives, which will prevent good-faith users from using their hardware. Many 3D printer owners also have no interest in printing firearm components. Most simply want the freedom to print trinkets and spare parts while others use them to print various items and sell them as an income stream.

A Chicago concert superfan Aadam Jacobs who has recorded more than 10,000 shows since the 1980s is working with Internet Archive volunteers to digitize the collection before the cassettes deteriorate. "So far, about 2,500 of these tapes have been posted on the Internet Archive, including some rare gems like a Nirvana performance from 1989," reports TechCrunch. From the report: For many of these recordings, Jacobs was using pretty mediocre equipment, but the volunteer audio engineers working with the Internet Archive have made these tapes sound great. One volunteer, Brian Emerick, drives to Jacobs' house once a month to pick up more boxes of tapes -- he has to use anachronistic cassette decks to play the tapes, which get converted into digital files. From there, other volunteers clean up, organize, and label the recordings, even tracking down song names from forgotten punk bands. The archive is available here.

Bloomberg's Mark Gurman reports that Apple is developing display-free AI smart glasses aimed at rivaling Meta's Ray-Bans, with multiple frame styles, a distinctive oval camera design, and tight iPhone integration. "The idea is to unveil the product at the end of 2026 or early the following year, with the actual release coming in 2027," writes Gurman. From the report: Like Meta's offering, Apple's glasses will be designed to handle everyday uses: capturing photos and videos, syncing with a smartphone for editing and sharing, handling phone calls, listening to notifications, playing music, and enabling hands-free interaction via a voice assistant. In Apple's case, that assistant will be a significantly upgraded Siri coming in iOS 27. The glasses are part of a broader, three-pronged AI wearables strategy that also includes new AirPods and a camera-equipped pendant. Each device is designed to leverage computer vision to interpret the user's surroundings and feed contextual awareness into Siri and Apple Intelligence. That will enable features like improved turn-by-turn map directions and visual reminders.

When Apple typically enters a new product category, it offers clear advantages over what's currently available. We saw this with the original iPod, iPhone, iPad and Apple Watch -- and, even though it was a flop, the Vision Pro. That approach won't be as obvious with Apple's upcoming foldable iPhone, but we should see it on full display with the glasses. According to employees working on the project, Apple's strategy is to outdo competitors by tightly integrating the glasses with the iPhone and offering a higher-end build. While Meta relies heavily on partner EssilorLuxottica SA for frames, Apple is unsurprisingly planning to go at it alone in terms of design. That also should set it apart from Alphabet Inc.'s Google and Samsung Electronics Co., which are leaning on Warby Parker.

Apple's design team has whipped up at least four different styles and plans to launch some or all of them, I'm told, as well as many color options. The latest units are made from a high-end material called acetate, which is known to be more durable and luxurious than the standard plastic used by many brands. Here are the designs in testing:
- A large rectangular frame, reminiscent of Ray-Ban Wayfarers
- A slimmer rectangular design, similar to the glasses worn by Apple Chief Executive Officer Tim Cook
- Larger oval or circular frames
- A smaller, more refined oval or circular option

"Robotic bird decoys are being deployed at Grand Teton National Park," reports Interesting Engineering, "to influence the behavior of real sage grouse and help restore a declining population.". Robotics mentor Gary Duquette describes the machines as "kind of a Frankenbird." (SFGate shows one of the robot birds charging up with a solar panel... "Recorded breeding calls are played at the scene, with clucking and cooing beginning at 5 a.m. each day.")

Duquette builds the birds with a team of high school students, telling WyoFile that at school they "don't really get to experience real-world problems" where failures lurk. So while their robot birds may cost $150 in parts, the practical experience the students get "is priceless." Spikes in the electric currents burned out servo motors as the season of sagebrush serenades loomed, Duquette said. "The kids had to learn the difference between voltage and amperage...." To resolve the problem, the team wired a voltage converter in line with the Arduino controller and other elements on an electronic breadboard. "We pulled through and got it done in time," he said...

A noggin fabricated by a 3D printer tops the robo-grouse. Wyoming Game and Fish staffers in Pinedale supplied grouse wings from hunter surveys, and body feathers came from fly-tying supplies at an angling store. Packaging foam from a Hello Fresh meal kit replicates white breast feathers, accented by yellow air sacs...
The Independent wonders if more national parks would be visited by robot birds... During this year's breeding season, which runs through mid-May, researchers are using trail cameras to track whether real sage grouse respond to the robotic displays and return to the restored lek sites. If successful, officials say similar robotic systems could eventually be used in other national parks facing wildlife management challenges.

A new powerful chipset has arrived to take on x86 CPUs and Apple's M5, writes Wccftech.

The blog Windows Central writes that "Qualcomm's Snapdragon X2 processors are here" — and they run Windows: Microsoft has done a massive amount of work to improve compatibility and has also convinced developers to embrace Windows 11 on Arm. Users of Windows 11 on Arm PCs spend 90% of their time on Arm-based apps that run natively. Additionally, apps that do not run natively can often run through Prism emulation, which has improved dramatically since launch...

[A]pp compatibility issues are overblown by many, and unfortunately those sharing false information are the same folks people rely on to make purchases... Works on Windows on Arm maintains a list of compatible apps and games for the platform. There, you'll see well-known apps like Google Chrome, the Adobe Creative Suite, and Spotify. We also have a collection of the best Windows on Arm apps to help you out. Snapdragon X PCs aren't gaming PCs, but there is a growing library of games that can run on the chips.

"RGB LED TVs have been the talk of the TV world this year," argues The Verge, with models coming from all the manufacturers." And the first one of 2026 is here — the UR9 from China's Hisense — "the first look at the viability of the new backlight technology outside of demo rooms." They call it "a step above the traditional mini-LED TVs of years past." and "a great first shot against OLED's bow." HDR is colorful and accurate, it has great brightness, and it is capable of showing colors beyond the P3 color space for movies and TV shows that have wider color. But at $3,500, the 65-inch model I reviewed is priced comparably to high-end OLEDs from LG and Samsung, which is tough competition... One of the touted benefits of RGB LED TVs is their ability to achieve 100 percent of the BT.2020 color space... [But] even if a TV is capable of extending beyond P3 and into BT.2020 colors (which the UR9 absolutely is), with most movies and TV shows it doesn't matter. It's also a bit of a chicken-or-the-egg situation — we need TVs that can accurately display BT.2020 before the color space is fully adopted by TV and movie creators, but if there's no content, why get a BT.2020 TV?
BGR points out this new mini LED TV also "includes a DisplayPort (DP) connection alongside HDMI."

"Well, technically, it's a USB-C port that delivers full DisplayPort functionality, but it's labeled as DisplayPort." The TV also has three HDMI 2.1 ports, making it a great choice for game consoles and PCs. And while HDMI 2.1 supports 4K/120Hz, the Hisense UR9S will deliver 4K/170Hz or 4K/180Hz visuals [a higher refresh rate] when connected to a gaming PC via DisplayPort. Better yet, the TV is AMD FreeSync-compatible, and Hisense plans on adding Dolby Vision 2 HDR in future firmware.

The Hisense UR9S will be available in four sizes: 65, 75, 85, and 100 inches. It's worth mentioning that the two largest sizes will max out at 180Hz for the refresh rate, while the 65 and 75-inch screens come in at 170Hz. This is exciting news for serious gamers looking for the best gaming TVs and a huge step forward in the evolution of panel tech. RGB Mini LED TVs were showcased by a handful of manufacturers at CES 2026, including Samsung, Sony, and LG; so Hisense will certainly have some competition.

Bloomberg describes him as a "former Harvard Medical School professor whose research has focused on the intersection of AI and neuroscience."

"For the past 20 years, I studied how the human brain stores and retrieves memories," Kreiman writes on LinkedIn. And now "My co-founder Spandan Madan and I built a new algorithm to endow humans with perfect and infinite memory." Engramme connects to your **memorome**, i.e., entire digital life. Large Memory Models work in the same way that your brain encodes and retrieves information. Then memories are recalled automatically — no searching, no prompting, no hallucinations. [The startup's web site promises "omniscient AI to augment human cognition."]

We have built the memory layer for EVERY app. Read our manifesto about augmenting human cognition. ["We are not just building software; we are enabling a complete transformation of human cognition. When the friction disappears between needing a piece of information and recalling it, the nature of thought itself changes. This synergy between biological intuition and digital precision will be the most disruptive force in modern history, fundamentally reshaping every profession... We are dedicated to creating a world where everyone has the power to remember everything they have ever learned, seen, or felt "]

Welcome to a new future where you can remember everything. This is the MEMORY SINGULARITY: after 300,000 years, this is the moment that humans stop forgetting.
Bloomberg reports that the startup (spun out of a lab at Harvard) is "in talks with investors to raise about $100 million, according to people familiar with the matter."

"Only about 2% of visually impaired people in the United States use guide dogs," notes StudyFinds.com, "partly because breeding and training takes years and fewer than half the dogs in training actually graduate."

But someday there could be another option: What if you could ask your guide dog where the nearest water fountain is and hear it answer back, complete with directions and an estimated walk time? Researchers at the State University of New York at Binghamton have built a robotic guide dog that can do something close to that, holding simple back-and-forth conversations about navigation with its handler, describing the surrounding environment, and talking through route options as it leads the way... Their work, presented at the 40th Annual AAAI Conference on Artificial Intelligence, pairs a large language model, a system that understands and generates language, with a navigation planner. Together, the two let the robot understand open-ended requests, suggest destinations, and adjust plans on the fly.

In 2024 the Verge's consumer tech reporter paid $173 for a WD Black SN850X 2TB SSD. But "now that same SSD costs $649..."

"Like with RAM, demand from the AI industry is swallowing up supply from a limited number of manufacturers, leading to a drastic reduction in the inventory that's available to consumers" — and skyrocketing prices: The price on my WD Black drive nearly quadrupled since November 2025, and consumer SSDs across the board are seeing similar increases, much like with RAM. The 4TB version of the popular Samsung 990 Pro SSD previously cost $320, but will now run you nearly $1,000. External SanDisk SSDs saw a 200 percent price hike at the Apple Store in March....

According to price trends from PC Part Picker, NVMe SSD prices began ticking upward in December 2025, with prices on 256GB to 4TB SSDs now double or triple what they were just a few months ago, and continuing to climb.

Amazon CEO Andy Jassy says the company may eventually sell its Trainium AI chips directly to outside customers, not just through AWS, which would put Amazon in more direct competition with Nvidia. "There's so much demand for our chips that it's quite possible we'll sell racks of them to third parties in the future," Jassy wrote in his annual shareholder letter Thursday. He also revealed the company's chip business is already running at more than $20 billion annually, with demand so strong that current and even future generations are largely spoken for. Quartz reports: Access to Amazon's chips is currently limited to Amazon Web Services, with customers paying for cloud-based usage rather than owning any physical hardware. Selling to AWS and external customers alike, as standalone chipmakers do, would put annual revenue at around $50 billion, up from the $20 billion the company estimates for the year, Jassy said. The $20 billion figure spans three product lines: Trainium, the AI accelerator chip; Graviton, a general-purpose processor; and Nitro, a chip that helps run Amazon's EC2 server instances. All three are growing at triple-digit rates year over year, Jassy claimed in his letter.

Jassy said demand for Trainium has outpaced supply at each generation. Trainium2 is essentially unavailable, with its entire allocated capacity spoken for. Trainium3 started reaching customers in early 2026, and reservations have filled nearly all available supply. Even Trainium4 -- which is not expected to reach wide release for another year and a half -- has substantial pre-orders committed. Jassy argued that a full-scale Trainium rollout could shave tens of billions off annual capital costs while meaningfully widening profit margin.

Starting May 20th, Amazon will stop Kindle Store access for Kindle and Kindle Fire devices released in 2012 and earlier. After that date, those devices will "no longer be able to purchase, borrow, or download new content." Owners can still read content already on the device, but if an affected device is reset or deregistered after the cutoff, it can't be re-registered. The Verge reports: The complete list of affected devices goes all the way back to the original Kindle that launched in 2007 with a full keyboard and scroll wheel. [...] Amazon will be notifying affected users over email ahead of May 20th with an explanation of what their older devices can and cannot do. Pre-2012 Kindle Fire devices will be subjected to the same limitations as Kindle e-readers when it comes to books, but other apps and Amazon services on those devices won't be impacted.

For longtime users wanting to take the opportunity to upgrade to newer Kindle hardware, Amazon will offer a 20 percent discount on new Kindle devices and a $20 ebook credit that will be added to their accounts after upgrading, valid until June 20th, 2026, at 11:59PM PT. Their older purchases will be available on new devices as long as they log in to the same account they've been using for the past 14 years or more.

An anonymous reader quotes a report from Ars Technica: Apple earned the lowest grades in a report on laptop and smartphone repairability released today by the consumer advocacy group Public Interest Research Group (PIRG) Education Fund. The report, which looks at how easy devices are to disassemble and how easy it is to find repairability information, gave Apple a C-minus in laptop repairability and a D-minus in cell phone repairability. For its "Failing the Fix (2026): Grading laptop and cell phone companies on the fixability of their products" report, PIRG analyzed the 10 newest laptops and phones that were available via manufacturers' French website in January. [...] Apple leads the list of laptop repairability losers, largely due to it having low disassembly scores. Apple, along with Dell and Samsung, also lost a full point for being members of TechNet and the CTA. Lenovo had the second-worst grade with a C-minus. Like Apple, Lenovo had low disassembly scores.

It also lost 0.5 points for failing to properly post PDFs explaining the French repair scores for some of its newest laptops sold in the region, as required in France. This is especially noteworthy because Lenovo got an F in last year's report for missing this information on at least 12 laptops. At the time, Lenovo director of communications David Hamilton provided a statement to Ars saying that the missing information was "due to a backend web compatibility issue that temporarily prevented the display of repairability scores on our Lenovo France website" that was "widely resolved." However, it appears that over a year later, Lenovo still isn't providing sufficient information to meet France's requirements

"While Lenovo has improved somewhat with their compliance with French consumer law by providing more repair score PDFs on their website, we urge the company to resolve this multi-year issue," this year's report says. PIRG's report concluded that "laptops are pretty stagnant in terms of repairability" across many of the eight most popular laptop brands in the US. However, Proctor noted to Ars that consumers' access to parts, tools, and information that vendors have has improved, but improvements around ease of disassembly "take longer to realize." He also praised vendors' efforts to release more repairable designs, such as Apple's MacBook Neo. For its repairability index, PIRG weighed physical ease of disassembly most heavily, while also considering the availability of repair documentation, spare parts, spare-parts affordability, and other product-specific criteria. It then adjusted company grades by deducting points for membership in trade groups that oppose right-to-repair laws and adding small bonuses for manufacturers that supported right-to-repair legislation.

Acer stood out as the only laptop vendor that avoided the 0.5-point trade-group penalty, since it was not listed as a member of TechNet or the Consumer Technology Association.

Apple may have a supply problem on its hands with the MacBook Neo... The laptop reportedly relies on "binned" A18 Pro chips with one GPU core disabled, and demand is so strong that the supply of those cheaper leftover chips could run out before the next model is ready. That leaves Apple choosing between lower margins, shifting production plans, or changing the lineup to keep its $599 hit product in stock. MacRumors reports: The all-new MacBook Neo has been such a hit that Apple is facing a "massive dilemma," according to Taiwan-based tech columnist and former Bloomberg reporter Tim Culpan. [...] In the latest edition of his Culpium newsletter today, Culpan said the MacBook Neo is selling so well that Apple's supply of the binned A18 Pro chips with a 5-core GPU will "run out" before the company is able to fully satisfy demand for the laptop. Apple's initial plan was to have suppliers build around five to six million MacBook Neo units before ceasing production of the model with the A18 Pro chip, he said, but it sounds like demand is so strong that Apple might run out of A18 Pro chips to put in the MacBook Neo before the second-generation MacBook Neo with an A19 Pro chip is ready next year. Apple is unlikely to mark the MacBook Neo as temporarily sold out, so it may be forced to take action, but profit margins might be affected.

A18 Pro chips are manufactured with TSMC's second-generation 3nm process, known as N3E, and Culpan said TSMC's N3E production lines are currently operating at maximum capacity. As a result, he said that Apple may have to pay a premium to restart A18 Pro chip production for the MacBook Neo, which would lower its profit margins. Apple would have to disable a GPU core on these chips to ensure that they have only a 5-core GPU, like all other MacBook Neo units sold to date. Alternatively, Culpan said that Apple could reallocate some of its chip production that was originally planned for other devices, but he said the cost would still be higher than what it paid for its initial batch of A18 Pro chips.

Culpan speculated that Apple could also opt to discontinue the $599 model with 256GB of storage, leaving the $699 model with 512GB of storage and a Touch ID button as the only configuration available. This is unlikely to happen any time soon, in our view, given how heavily Apple has been promoting the MacBook Neo's affordability. Apple might also be able to move up the release of a MacBook Neo with the iPhone 17 Pro's A19 Pro chip, but that too would be a costlier option, at least until the company achieves a sufficient stockpile of binned A19 Pro chips with a 5-core GPU. In any case, Apple could opt to keep the starting price of current and future MacBook Neo models at $599 and simply accept lower profit margins on the laptop, especially given that it attracts customers to the macOS and broader Apple ecosystem.
