Last month NXP posted open-source Linux kernel driver patches for their Neutron NPU accelerator. The NXP Neutron NPU aims to help with edge AI applications and this neural processing unit is found in their different SoCs. Unfortunately, their GitHub repository for the user-space software ends up containing a binary-only blob that will end up delaying plans on getting this driver into the mainline Linux kernel…

Oversight Board tells Meta expanding Community Notes outside of US poses ‘significant’ risks
Meta didn’t consult its Oversight Board last year when it announced sweeping policy changes to content moderation and a rollback of third-party fact checking in the United States in favor of Community Notes. But the company did ask the board for advice on how to expand the crowd-sourced fact checks to other countries.
Now the Oversight Board is publishing its advice to Meta. In a 15,000-word policy advisory opinion, the group urged Meta to be cautious with an international rollout, warning that an expansion of the program could “pose significant human rights risks and contribute to tangible harms” if safeguards are not put in place.
The board, notably, was asked to weigh in on a fairly narrow set of questions, including how it should evaluate whether to withhold the feature in certain countries. Meta “respectfully” asked the Oversight Board to avoid “general” critiques about the system, which it has said is modeled after X.
In its opinion, the Oversight Board said that Community Notes “could enhance users’ freedom of expression and improve online discourse” with enough safeguard. But it recommended Meta withhold the feature in countries with “high polarization,” as well as countries in the midst of a crisis or “protracted conflict.” The board also said that Meta should avoid countries with a history of organized disinformation networks, because the notes may be more easily manipulated in such places, and countries with “linguistic complexity” that Meta may be ill-equipped to understand.
Depending on how you interpret that advice, that could exclude quite a few countries, though the board stopped short of making country-specific recommendations. Still, it raises questions about how closely Meta will follow the suggested guidelines. For example, the United States could be considered a country with “high polarization.” (Community Notes has been live in the US for more than a year.)
While the Oversight Board was careful to say it “neither endorses nor opposes” an expansion of Community Notes, it did discuss Meta’s approach to fact checking, noting that its partnerships with outside fact-checking organizations are still largely in place outside of the US. And the opinion cautions against ending these relationships, noting that research into Community Notes on X shows that authors writing notes often rely on work done by professional fact checkers.
“Community Notes and fact checking are not mutually exclusive,” Oversight Board member Paolo Carozza tells Engadget. “One doesn’t have to replace or substitute for the other, they can coexist. And in some situations, there are really important reasons for them to coexist. The board really deliberately stayed away from any kind of suggestion that the introduction of Community Notes ought to result in the removal or ending of fact checking.”

Xcadey’s new bike computer is another cut-price challenger to Garmin and Wahoo
Xcadey has announced its entry into the cycling computer market with its literally named Bike Computer on display at the Taipei International Cycle Show.
The brand is a partner of Euskaltel-Euskadi and has been making power meters for over a decade.
The new device has many of the features riders have come to expect, including offline mapping, navigation and sensor connectivity.
GPS, BeiDou and GLONASS are all supported by the device, meaning position accuracy should be pretty good.

The device has a 3.2in display with a 480×800 resolution touchscreen, which offers good clarity but may be difficult to navigate in the rain.
Behind the screen, the brand says the computer runs on Android software powered by a 12mm high-performance chip.

I tried the device and it’s much like a smartphone in terms of refresh rate.
A benefit of using the Android OS is the possibility to integrate training apps directly into the device, which Xcadey says it is looking into.

The brand claims battery life will be around 20 hours, and that the device is IP67-rated.
We’ve seen other brands, such as Bryton, make quick impacts in the cycle computer market and Xcadey is looking to do the same.

The price, while not confirmed, is expected to be around the €150 mark and the Bike Computer is expected to launch in time for summer.

Wheeltop expands its challenge to SRAM and Shimano with new wireless groupset
Wheeltop is displaying many of its EDS groupsets at this week’s Taipei International Cycle Show, and nestled away at the back of its stand, we spotted an unreleased TT groupset.
The new groupset looks to use the same derailleurs as the TX road groupset, with the system fully wireless.
The brake levers feature a hydraulic cable port, although there were no callipers on display to match the groupset.

Buttons on the levers enable you to shift gears when out of the tri-bars, and the blades themselves are made from a carbon fibre composite.
The shifters feature a simple up and down ergonomic, and they both feel good in the hand.

We asked for more details about the launch, but all we were told was that it’s expected in the coming months.
Wheeltop has been seen as a challenger to established brands SRAM and Shimano, with the new groupset expanding its reach.

Elsewhere on the stand, Wheeltop is showing off its first cranksets.
This has been something missing from the brand’s line-up until now, with buyers required to look elsewhere to complete their drivetrain.
The cranks feature four carbon fibre finishes and come in an array of sizes.

The toughest bike lock I’ve ever tested now has a smaller, lighter and cheaper option
Litelok’s X1 bike lock and its pricier X3 stablemate are immensely tough against hand tools and physical attacks, making them the best overall bike locks I’ve tested.
It was Litelok’s anti angle-grinder performance that really impressed me in testing, but the downside of the X1, X1 Plus and X3 is their size. These locks are fine if you need to secure a hefty cargo bike or an eMTB, but they’re somewhat bulky at around 2kg.
If you want the ultimate in security but are looking for something a little more portable, the options have been thin on the ground.
That’s where the new X1 Mini comes in.
Made in Wales

Litelok inventor and founder, Neil Barron, says: “We designed the new X1 Mini after lots of customer requests. It’s still made in the same way in Wales, at our solar powered Swansea factory. It gets the same level of Barronium armour technology and the same tough lock mechanism.”
Barronium is a fused composite armour made up of multiple, extremely hard ceramic and metallic materials that, combined, make it tougher than an angle-grinder disc. Barronium repels attacks by turning the grinder’s energy and force on itself.
Like its stablemates, the new X1 Mini has attained Sold Secure Cycle Diamond status, along with Sold Secure Powered Cycle Diamond and ART4 insurance-rated standards.
It also meets the ‘Police Preferred Specification’ of Secured by Design (SBD), providing the best available deterrent for cyclists and motorcyclists looking to secure bicycles, ebikes, motorcycles and scooters.

The X1 Mini is priced at £139.99, £50 cheaper than the X1 Plus and £10 less than the standard X1. It weighs half a kilogram less than the X1 Plus and X3, and is 6cm shorter.
The new lock comes with a frame mount, with Restrap’s smart belt-loop holster available separately.

Melania Trump Welcomes Humanoid Robot At White House Summit
Longtime Slashdot reader theodp writes: In Melania and the Robot, the New York Times reports on First Lady Melania Trump’s inaugural Fostering the Future Together Coalition Summit, which brought together international leaders, First Spouses from around the world, tech leaders, educators, and nonprofits to collaborate on practical solutions that expand access to educational tools while strengthening protections for children in digital environments (Day 2 WH summary). The Times begins:
“On Wednesday, Mrs. Trump appeared at the White House alongside Figure 3, a humanoid, A.I.-powered robot whose uses, according to the company that makes it, include fetching towels, carrying groceries and serving champagne. But Mrs. Trump joins tech executives and some researchers in envisioning a world beyond robot butlery. She is interested in how these robots could cut it as educators. Both clad in shades of white, the first lady and the visiting robot walked into a gathering of first spouses from around the world, a group that included Sara Netanyahu of Israel, Olena Zelenska of Ukraine, and Brigitte Macron of France. The dulcet tones from a (presumably human) military orchestra played as the first lady and her guest entered the event. Both lady and robot extolled the virtues of further integrating robots into the educational and social lives of children. In the history of modern first-lady initiatives, which have included building a national book festival (Laura Bush), reshuffling the food pyramid (Michelle Obama) and advocating for free community college (Jill Biden), Mrs. Trump’s involvement of a humanoid robot in education policy was a first.”
“Figure 3 delivered brief remarks and delivered salutations in several languages. With its sleek black-and-white appearance, Figure 3 would fit right in with the first lady’s branding aesthetic, which includes a self-titled coffee table book and movie, not least because the name “MELANIA” was emblazoned on the side of its glossy plastic head. After Figure 3 teetered gingerly away, Mrs. Trump looked around the room and told them that the future looked a lot like what they had just witnessed. ‘The future of A.I. is personified,’ she told her audience. ‘It will be formed in the shape of humans. Very soon artificial intelligence will move from our mobile phones to humanoids that deliver utility.’ She invited her guests to envision a future in which a robot philosopher educated children.”

Brazil’s UFO Capital Marks 30 Years Since ‘Alien Encounter’
Thirty years after the alleged 1996 “ET of Varginha” encounter, debate continues to rage over the events that happened in Brazil’s self-styled UFO capital. An anonymous reader quotes an excerpt from the Guardian: The skies over this far-flung coffee-growing hub went charcoal black, the heavens opened and one of Brazil’s greatest mysteries was born. “It really was something unique,” recalls Marco Antonio Reis, a zoo director, who was at his ranch outside Varginha one stormy day in January 1996 when, he says, an otherworldly creature came to town. Reis and other locals claim the unusually ferocious downpour heralded a series of disturbing and seemingly paranormal events. At least six of the zoo’s animals, including a spider monkey, a tapir and a raccoon, died mysteriously after a horned interloper with bulging red eyes was spotted in the vicinity by a woman who had gone out for a smoke. When a vet examined their corpses, “they were all black inside,” Reis claims.
On a nearby wasteland, three young women spotted a peculiar and malodorous being with a heart-shaped face and three lumps on its head cowering beside a wall. “I’ve seen the devil,” one of those witnesses would later tell her mum. Soon afterwards, an unexplained infection was rumored to have killed a strapping police intelligence officer who was said to have grappled with the oleaginous unidentified being. Three decades later, Reis says he is convinced Varginha received a non-human visit. His only doubt was from where it came.
“We don’t know if it was extraterrestrial or intraterrestrial,” the 71-year-old says as he climbs a staircase to the veranda where the smoker claims to have seen what, in reference to Steven Spielberg’s 1982 film, became known as the “ET of Varginha”. A 2ft statue of a two-toed alien now marks the spot. “It’s possible it was an intraterrestrial, from inside the Earth They don’t just come from space,” Reis says. “It might have come from the depths of the Earth, too. We don’t even know what it’s like at the bottom of the sea, do we?”

All About the New Princeton Carbonworks Alta 3532 Wheels in Zwift
Princeton Carbonworks arrived in Zwift last week, with three wheelsets released to the game: the Alta 3532, the Wake 6560 White, and the Mach TSV2/Blur Disc. Today, we’re looking at the Alta 3532 wheels, which are ultra-lightweight climbing wheels.
Here’s what the Drop Shop says about them: “Float up the climbs. Flow through the corners. A light-on-your-feet feeling with instant acceleration, effortless rhythm, and the kind of ride that makes every effort feel smoother.”

The wheels are now available in the Drop Shop, accessible at level 35 and above, for 685,000 Drops. They are rated 3 stars for aero and 4 for weight, so we expected them to climb quite well. But since Zwift’s 4-star rating system isn’t precise enough for our taste, we ran these wheels through our standard battery of tests to determine exactly how they perform in Zwift and stack up against other wheelsets in game.
Let’s dive in and learn all about the performance of this wheelset from Princeton Carbonworks…
Aero (Flat/Rolling) Performance

Princeton’s Alta 3532 wheels deliver “midpack” aero performance, which isn’t surprising considering their profile.
They are 26.8 seconds faster across an hour of flat riding compared to our baseline 32mm wheels. This puts them effectively neck and neck with the Zipp 353 NSW wheels, the top climbing wheels in the game. For comparison, the most aero non-disc hoops in game (ENVE SES 8.9) put 46.7 seconds into the baseline wheels across an hour.
Climb Performance

When the road tilts upward steeply, the Alta 3532 really shine! They outclimb every other wheelset in the game, and by a significant margin.
Princeton’s Alta 3532 wheels gain 14.1 seconds over our baseline wheels in an hour of climbing, beating the current top climbers (Zipp 353 NSW and Lightweight Meilenstein) by 4.3 seconds.
Note: all test results above are from a 75kg, 183cm rider holding 300W steady using the Zwift Carbon frame.
Conclusions
The Alta 3532 wheels from Princeton are Zwift’s new top climbing wheels, edging out the Zipp 353 NSW and Lightweight Meilenstein, which were effectively tied for the top spot.
Their aero performance is rather lackluster, though, so racers may want to look at one of the all-arounder wheelsets for all but the steepest and longest race climbs.
(Speaking of all-arounders, look for a post on Princeton’s new Wake 6560 wheels to drop soon. Their performance on the flats and climbs is second to none!)

Postal Service to Impose Its First-Ever Fuel Surcharge on Packages
The U.S. Postal Service plans to impose its first-ever fuel surcharge on packages (source paywalled; alternative source), adding an 8% fee starting in April as it struggles with rising fuel costs and ongoing financial pressure. The surcharge will not apply to letter mail and is currently expected to remain in place until January 2027. The Wall Street Journal reports: Other parcel carriers, including FedEx and United Parcel Service, have imposed fuel surcharges, as well as a basket of other surcharges and fees, for years. Both FedEx and UPS have dramatically raised their fuel surcharges in recent weeks as the price of oil has increased amid the turmoil in the Middle East. […] The post office has been trying to increase the volume of packages it delivers. It previously differentiated itself from commercial carriers by saying that it doesn’t apply residential, Saturday delivery or fuel or remote-delivery surcharges.

Attaching A Giant Sword To An Excavator
Because some people are still out there having fun (crazy to think about), this is a video of Youtuber Handy Geng making a giant sword (inspired by Ichigo’s Soul-Cutter sword from manga Bleach), then attaching it to the business end of an excavator. Well, provided the business end is the excavator’s arm, MY business end is the rear *wink* The swordcavator lacks the speed to do any real slashing damage, but it’s still plenty capable of piercing (like my roommate’s voice) and crushing (like the weight of life). *runs AI feel-good check on post, AI terminates its own session* Sometimes they be like that though.
Canada’s Immigration Rejected Applicant Based On AI-Invented Job Duties
New submitter haroldbasset writes: Canada’s Immigration Department rejected an applicant because the duties of her current job did not match the Canadian work experience she had claimed, but the Department’s AI assistant had invented that work experience. She has been working in Canada as a health scientist — she has a Ph.D. in the immunology of aging — but the AI genius instead described her as “wiring and assembling control circuits, building control and robot panels, programming and troubleshooting.” “It’s believed to be the first time that the department explicitly referred to the use of generative AI to support application processing in immigration refusals,” reports the Toronto Star. “The disclaimer also noted that all generated content was verified by an officer and that generative AI was not used to make or recommend a decision.”
The applicant’s lawyer was shocked “how any human being could make this decision.” “Somehow, it hallucinated my client’s job description,” he said. “I would love to see what the officer saw. Something seriously went wrong here.”
The applicant’s refusal came just as Canada’s Immigration Department released its first AI strategy, which frames artificial intelligence as a way to improve efficiency, service delivery, and program integrity. The department says it has long used digital tools like analytics and automation to flag fraud risks and triage applications, and is now also experimenting with generative AI for tasks such as research, summarizing, and analysis. In this case, however, the department insisted the decision was made by a human officer and that generative AI was not involved in the final decision.

Roblox Gift Cards Are Majorly Discounted During Amazon’s Big Spring Sale
We may earn a commission from links on this page. Deal pricing and availability subject to change after time of publication.
If money was on sale 20% off, you’d buy a ton of it, right? Well, this Roblox gift card is “worth” $100 in Robux, the online currency used on the gaming platform Roblox, but it’s on sale for $80 during Amazon’s Big Spring Sale. If you’re reading this, chances are good that at some point in the next day/week/month, your child is going to hassle you for Robux anyway, so you might as well pay 20% less. (Your purchase also comes with a free “virtual item,” but your child doesn’t care about that.)
Speaking of children, parents, listen up: If you keep a bunch of these cards around, you’ll never have to scramble for a last minute present again, whether for your kid’s Easter basket or the birthday party you forgot about until the invite reminder showed up on your phone. The chances are very good that any kid who gets a Roblox gift card is going to like it better than all the stupid educational toys they were given, making your kid the hero of the day.
Amazon doesn’t put these cards on sale often, and not usually at such a deep discount. Here’s a chart to show you how relatively rare an occurrence it is:

The point is, don’t wait. It will hurt 20% less next time your kid asks you to give them real money to spend on virtual items in a game they will probably tire of within a week. I love Roblox.
