Long-time Slashdot reader MojoKid writes: AMD took the wraps of its next gen RDNA 4 consumer graphics architecture Friday, which was designed to enhance efficiency over the previous generation, while also optimizing performance for today’s more taxing ray-traced gaming and AI workloads. RDNA 4 features next generation Ray Tracing engines, dedicated hardware for AI and ML workloads, better bandwidth utilization, and multimedia improvements for both gaming and content creation. AMD’s 3rd generation Ray Accelerators in RDNA offer 2x the peak throughput of RDNA 3 and add support for a new feature called Oriented Bounding Boxes, that results in more efficient GPU utilization. 3rd Generation Matrix Accelerators are also present, which offer improved performance, along with support for 8-bit float data types, with structured sparsity.
The first cards featuring RDNA 4, the Radeon RX 9070 and 9070 XT go on sale next week, with very competitive MSRPs below $600, and are expected to do battle with NVIDIA’s GeForce RTX 5070-class GPUs
The article calls it “a significant step forward” for AMD, adding that next week is “going to be very busy around here. NVIDIA is launching the final, previously announced member of the RTX 50 series and AMD will unleash the 9070 and 9070 XT.”
“We need a license to allow us to make some of the basic functionality of Firefox possible,” Mozilla explained Wednesday in a clarification a recent Terms of Use update. “Without it, we couldn’t use information typed into Firefox, for example. It does NOT give us ownership of your data or a right to use it for anything other than what is described in the Privacy Notice.”
But Friday they went further, and revised those new Terms of Use “to more clearly reflect the limited scope of how Mozilla interacts with user data,” according to a Mozilla blog post. More details from the Verge:
The particular language that drew criticism was:
“When you upload or input information through Firefox, you hereby grant us a nonexclusive, royalty-free, worldwide license to use that information to help you navigate, experience, and interact with online content as you indicate with your use of Firefox.”
That language has been removed. Now, the language in the terms says:
“You give Mozilla the rights necessary to operate Firefox. This includes processing your data as we describe in the Firefox Privacy Notice. It also includes a nonexclusive, royalty-free, worldwide license for the purpose of doing as you request with the content you input in Firefox. This does not give Mozilla any ownership in that content….”
Friday’s post additionally provides some context about why the company has “stepped away from making blanket claims that ‘We never sell your data.'” Mozilla says that “in some places, the LEGAL definition of ‘sale of data’ is broad and evolving,” and that “the competing interpretations of do-not-sell requirements does leave many businesses uncertain about their exact obligations and whether or not they’re considered to be ‘selling data.'” Mozilla says that “there are a number of places where we collect and share some data with our partners” so that Firefox can be “commercially viable,” but it adds that it spells those out in its privacy notice and works to strip data of potentially identifying information or share it in aggregate.
Hidden layers of rock below the surface of Mars “strongly suggest” the presence of an ancient ocean, according to an international team of scientists including researchers at Penn State.
From the university’s announcement:
The new research offers the clearest evidence yet that the planet once contained a significant body of water and a more habitable environment for life, according to Benjamin Cardenas, assistant professor of geology at Penn State and co-author on the study. “We’re finding places on Mars that used to look like ancient beaches and ancient river deltas,” Cardenas said. “We found evidence for wind, waves, no shortage of sand — a proper, vacation-style beach.”
The Zhurong rover landed on Mars in 2021 in an area known as Utopia Planitia and sent back data on the geology of its surroundings in search of signs of ancient water or ice. Unlike other rovers, it came equipped with rover-penetrating radar, which allowed it to explore the planet’s subsurface, using both low and high-frequency radar to penetrate the Martian soil and identify buried rock formations. By studying the underground sedimentary deposits, scientists are able to piece together a more complete picture of the red planet’s history, Cardenas explained. When the team reviewed radar data, it revealed a similar layered structure to beaches on Earth: formations called “foreshore deposits” that slope downwards towards oceans and form when sediments are carried by tides and waves into a large body of water.
“This stood out to us immediately because it suggests there were waves, which means there was a dynamic interface of air and water,” Cardenas said. “When we look back at where the earliest life on Earth developed, it was in the interaction between oceans and land, so this is painting a picture of ancient habitable environments, capable of harboring conditions friendly toward microbial life.” When the team compared the Martian data with radar images of coastal deposits on Earth, they found striking similarities, Cardenas said. The dip angles observed on Mars fell right within the range of those seen in coastal sedimentary deposits on Earth…
The study also provided new information on the evolution of the Martian environment, suggesting that a life-friendly warm and wet period spanned potentially tens of millions of years.
Mars “was evolving,” Cardenas says in the announcement. “Rivers were flowing, sediment was moving, and land was being built and eroded.
“This type of sedimentary geology can tell us what the landscape looked like, how they evolved, and, importantly, help us identify where we would want to look for past life.”
CNN notes that the research was published Monday in the journal Proceedings of the National Academy of Sciences.
Active since 1995, the Comprehensive Perl Archive Network (or CPAN) hosts 221,742 Perl modules written by 14,548 authors. This week they announced that the CPAN Security Group “was authorized by the CVE Program as a CVE Numbering Authority (CNA)” to assign and manage CVE vulnerability identifications for Perl and CPAN Modules.
“This is great news!” posted Linux kernel maintainer Greg Kroah-Hartman on social media, saying the announcement came “Just in time for my talk about this very topic in a few weeks about how all open source projects should be doing this” at the Linux Foundation Member Summit in Napa, California. And Curl creator Daniel Stenberg posted “I’m with Greg Kroah-Hartman on this: all Open Source projects should become CNAs. Or team up with others to do it.” (Also posting “Agreed” to the suggestion was Seth Larson, the Python Software Foundation’s security developer-in-residence involved in their successful effort to become a CNA in 2023.)
444 CNAs have now partnered with the CVE Program, according to their official web site. The announcement from PerlMonks.org:
Years ago, a few people decided during the Perl Toolchain Summit (PTS) that it would be a good idea to join forces, ideas and knowledge and start a group to monitor vulnerabilities in the complete Perl ecosystem from core to the smallest CPAN release. The goal was to follow legislation and CVE reports, and help authors in taking actions on not being vulnerable anymore. That group has grown stable over the past years and is now known as CPANSec.
The group has several focus areas, and one of them is channeling CVE vulnerability issues. In that specific goal, a milestone has been reached: CPANSec has just been authorized as a CVE Numbering Authority (CNA) for Perl and modules on CPAN
San Francisco-based biotech startup Loyal says a drug it developed to increase dogs’ lifespan “has passed a significant milestone on the way to regulatory approval,” reports the Washington Post:
The Food and Drug Administration certified the daily pill as having a “reasonable expectation of effectiveness” at extending senior dogs’ lifespans. The regulator’s Center for Veterinary Medicine still has to certify that the drug is safe and that Loyal can manufacture it at scale before vets can prescribe the pill to dogs 10 years or older that weigh 14 pounds or more. Loyal’s CEO, Celine Halioua, estimates that the process should be complete by the end of 2025 and called the FDA’s initial recognition “a key step” to extending dogs’ lives…
In the past decade, a subculture of tech entrepreneurship has focused on helping people stave off death, hawking custom-made dietary supplements and $2,500 full-body MRIs and investing in the development of antiaging drugs, among many other efforts. According to data firm Pitchbook, about $900 million in venture capital has been poured into antiaging and longevity start-ups in the past 12 months. Loyal has raised more than $150 million in venture funding since its 2019 founding to develop lifespan-extending drugs initially focused on canines.
Launching veterinary drugs is in some ways easier than winning approval for human treatments. Because dogs and humans have evolved alongside one another, Halioua hopes to eventually apply her findings about pets to help prolong their owners’ lives. “If we can successfully delay the onset and severity of age-related diseases in dogs, it’s extremely compelling evidence that it will also do that in humans,” Halioua said. The biological processes of aging unfold faster in dogs because they live such short lives, she said, helping researchers and entrepreneurs probe how they work.
“Loyal’s pill is a result of research into how to mimic the life-extending benefit of caloric restriction without the appetite suppression,” according to the article, “and without the need for an owner to restrict their dog’s food.
“The drug aims to improve a dog’s metabolic fitness, or the body’s ability to convert nutrients into energy and regulate hormones, which declines in humans and canines with age…”
Magnus Carlsen “announced this week that he is auctioning off the Italian luxury brand jeans that started a dress code dispute at December’s World Rapid and Blitz Chess Championships,” reports the Associated Press. (“Condition: Pre-owned,” says the listing on eBay, where by Friday night bidding on the charitable auction was up to $14,100.)
But Carlsen drew more attention on The Joe Rogan Experience last week — partly by saying “I have no chance against my phone.” (Although he’d also described beating a fan’s computer program, according to Firstpost, by playing “some kind of anti-computer chess, where I just closed up the position as much as possible and gave it as few possibilities as possible to out-calculate me.”)
Carlsen admitted that he rarely plays against chess engines due to their overwhelming strength, but acknowledged their value as training tools. “I rarely play against engines at all because they just make me feel so stupid and useless. So, I think of them more as a tool than anything else.”
And this led Carlsen to add “If I started cheating, you would never know,” reports Indian Express:
It’s not just a throwaway line about cheating either. On a two-hour-long podcast, where he touches on mostly everything under the sun, Carlsen fixates on cheating in chess. He also details how a player of his calibre would need very little to cheat in chess. “I would just get a move here and there (from an aide). Or maybe if I am playing in a tournament I just find a system where I get somebody to signal to me when there’s a critical moment: a certain moment where a certain move is much better than the others. That’s really all I would need to go from being the best to being practically unbeatable. There’s so little you need in chess (to cheat). It really is a scary situation,” Carlsen said before pointing out how in 2010 the captain of the French chess team was helping a teammate decide his next move at the Olympiad just by standing in specific spots around the table…
“If you’re not cheating in a dumb way, there rarely is going to be a smoking gun. And without that smoking gun it is going to be really hard to catch people,” Carlsen admits on the podcast… “As long as there are monetary incentives for people to cheat, there will be cheating in chess,” says Carlsen on the podcast.
The article adds that Carlsen does not believe Hans Niemann used anal beads to cheat — and that he thinks Niemann has become a much better chess player since the incident. But…
“Top level chess has been based on trust a lot. I don’t trust Niemann. Other top players still don’t trust him and he doesn’t trust me,” says Carlsen. “There is still something off about him now. We played an over-the-board tournament in Paris last year where there was increased security and he didn’t play at nearly the same level there.”
New releases we picked up this week that belong on your reading list.

“Tesla is taking steps to launch a ride-sharing service that could compete directly with Uber, Lyft and Waymo,” reports Axios, noting that Tesla “has filed for a transportation charter-party carrier permit from the California Public Utilities Commission, Bloomberg reported Thursday.”
“That classification means Tesla would own and control the fleet of vehicles,” Bloomberg reported… “In its communications with California officials, Tesla discussed driver’s license information and drug-testing coordination, suggesting the company intends to use human drivers, at least initially,” Bloomberg reported. The company is seeking the same type of permit that Waymo uses to run its robotaxi business.Uber is gearing up to begin offering autonomous vehicle services in partnership with Waymo in Austin and Atlanta later this year.
The article also adds that Musk “told investors in January that ‘I’m confident that we will release unsupervised FSD in California this year,’ referring to the company’s Full Self-Driving system.” But “Tesla has yet to apply for a permit to operate driverless vehicles…” notes the EV blog Electrek, adding “This is just a step for Tesla to test ride-hailing services ahead of autonomy.”
Reuters also points out that “Earlier in October, Tesla revealed the Cybercab, a robotaxi concept that had no steering wheel or control pedals… He has said the Cybercab will go into production in 2026 and will also be available for customers to buy for less than $30,000.”
Side Quest, formerly called Mere Mortals, will premiere on March 26 on Apple TV+. It’s the spin-off/expansion series for Mythic Quest, a comedy show on the streaming service about a video game studio developing an MMORPG of the same name. All four episodes of Side Quest will be available on the service on the same day the season four finale of Mythic Quest drops on the platform. Side Quest will revolve around the lives of the fictional studio’s employees, as well as the players and fans impacted by the Mythic Quest game.
The show will take on an anthology format, with a bunch of actors taking on leading roles for each installment. It was created by Mythic Quest writers Ashly Burch, John Howell Harris and Katie McElhenney, who also served as executive producers. Burch plays the character of Rachel in the original show. Charlie Day, Megan Ganz and Rob McElhenney, who created the Mythic Quest series, served as executive producers for the spin-off, as well. Lionsgate, 3 Arts Entertainment and Ubisoft produced the show for Apple TV+.
In addition to announcing the show’s premiere, Apple has also released the official trailer for the show, which gives you a pretty good idea of its tone and what you can expect if you watch it.

Memory safety bugs are “eroding trust in technology and costing billions,” argues a new post on Google’s security blog — adding that “traditional approaches, like code auditing, fuzzing, and exploit mitigations — while helpful — haven’t been enough to stem the tide.”
So the blog post calls for a “common framework” for “defining specific, measurable criteria for achieving different levels of memory safety assurance.” The hope is this gives policy makers “the technical foundation to craft effective policy initiatives and incentives promoting memory safety” leading to “a market in which vendors are incentivized to invest in memory safety.” (“Customers will be empowered to recognize, demand, and reward safety.”)
In January the same Google security researchers helped co-write an article noting there are now strong memory-safety “research technologies” that are sufficiently mature: memory-safe languages (including “safer language subsets like Safe Buffers for C++”), mathematically rigorous formal verification, software compartmentalization, and hardware and software protections. (With hardware protections including things like ARM’s Memory Tagging Extension and the (Capability Hardware Enhanced RISC Instructions, or “CHERI”, architecture.) Google’s security researchers are now calling for “a blueprint for a memory-safe future” — though Importantly, the idea is “defining the desired outcomes rather than locking ourselves into specific technologies.”
Their blog post this week again urges a practical/actionable framework that’s commonly understood, but one that supports different approaches (and allowing tailoring to specific needs) while enabling objective assessment:
At Google, we’re not just advocating for standardization and a memory-safe future, we’re actively working to build it. We are collaborating with industry and academic partners to develop potential standards, and our joint authorship of the recent CACM call-to-action marks an important first step in this process… This commitment is also reflected in our internal efforts. We are prioritizing memory-safe languages, and have already seen significant reductions in vulnerabilities by adopting languages like Rust in combination with existing, wide-spread usage of Java, Kotlin, and Go where performance constraints permit. We recognize that a complete transition to those languages will take time. That’s why we’re also investing in techniques to improve the safety of our existing C++ codebase by design, such as deploying hardened libc++.
This effort isn’t about picking winners or dictating solutions. It’s about creating a level playing field, empowering informed decision-making, and driving a virtuous cycle of security improvement… The journey towards memory safety requires a collective commitment to standardization. We need to build a future where memory safety is not an afterthought but a foundational principle, a future where the next generation inherits a digital world that is secure by design.
The security researchers’ post calls for “a collective commitment” to eliminate memory-safety bugs, “anchored on secure-by-design practices…” One of the blog post’s subheadings? “Let’s build a memory-safe future together.”
And they’re urging changes “not just for ourselves but for the generations that follow.”
Alphabet has announced a new development for Taara’s technology that could lead to low-cost, high-speed internet connectivity, even in far-flung locations. Taara’s general manager, Mahesh Krishnaswamy, has introduced the Taara chip, a silicon photonic chip that uses light to transmit high-speed data through the air. The Taara chip is abut the size of a fingernail, far smaller than the technology the Alphabet division has been using. Taara Lightbridge, which is what its first-generation technology is called, is the size of a traffic light and uses a system of mirrors and sensors to physically steer light to where it needs to go. The new chip uses software instead.
Taara is a project under X, Alphabet’s moonshot factory. The high speed wireless optical link technology underpinning the project was originally developed for X’s Project Loon internet broadcasting balloons. Alphabet pulled the plug on Loon in 2021 and focused on Taara instead, using its technology to beam broadband across the Congo River and the streets of Nairobi. Even years before Loon shut down, Alphabet’s X was already toying with the idea of using light to beam internet and tested the technology in India.
Taara’s technology works by using a “very narrow, invisible light beam to transmit data at speeds as high as 20 gigabits per second, up to distances of 20 kilometers (12.1 miles).” It’s like traditional fiber, in the sense that it uses light to carry data, except that light doesn’t travel through cables. Instead, Taara’s hardware emits beams of light. The beams from two units must be aligned with each other to be able to form a secure link that can transmit data, which is why Lightbridge was fitted with the parts needed to be able to physically steer the light. Taara’s new chip doesn’t need those components: It contains hundreds of tiny light emitters controlled by software with automatic steering
Krishnaswamy said Taara’s light-beaming units will only take days to install instead of the months or years it can take to lay fiber. During tests in the lab, the Taara team was able to transmit data at speeds of 10 Gbps over a distance of one kilometer (0.62 miles) using two of the new chips. They’re now looking to improve the chip’s capacity and range by creating an “iteration with thousands of [light] emitters.” The team expects the chip to be available in 2026.

Amazon’s long-awaited update to its assistant is almost here. About 18 months after the company first previewed the “next-gen Alexa” built with generative AI, it unveiled Alexa+, and early access will be available starting in March. Alexa+ will exist alongside the older Alexa and will cost $20 a month, unless you have a Prime membership, which will make it free to use. The new assistant will come with all the modern upgrades that its contemporaries like the redesigned Siri or Gemini offer, like more conversational interaction, better contextual understanding and the ability to “summarize complex topics” and “make suggestions based on your interests.” But it does one thing differently, and it’s the way Amazon purports to integrate with third-party apps and the rest of the internet that could set it apart.
At the presentation, vice president of Alexa and Fire TV Daniel Rausch outlined three ways the new assistant can integrate with other services you use. Firstly, it already works with “tens of thousands” of integrations already available, with Uber, Sonos, Samsung and Xbox being a few of the many logos that were displayed when Rausch said this. Presumably, that means Amazon worked with these partners to get their apps to play nicely with Alexa+ through their APIs.
Secondly, for the large swath of the online world that doesn’t have apps or the resources to code an API just for Alexa+, the assistant should be able to scour the internet for their website and navigate it on your behalf. During the presentation, Rausch demonstrated how Alexa+ was able to go to the Thumbtack website to hire a professional to fix his oven. Instead of having to whip out a phone or laptop to click through menus himself, Rausch could just verbally tell Alexa+ what he needed and what times he was available, and the AI did the rest.
Sam Rutherford for Engadget
This example in particular struck me as very similar to Google’s restaurant-reservation system Duplex, which, since way back in 2018, could call businesses on your behalf to book a table. All you had to do was tell Google what date and times you were considering, how many people were in your party and it would make the call for you, even speaking in a human-sounding voice to the restaurant. The way Alexa+ would click around websites on your behalf seems like Duplex on steroids.
Finally, Alexa+ can work with the “AI agents” on other sites, so you can talk to just one assistant instead of dozens of chatbots. In the presentation, Rausch got Alexa+ to work with the AI music generator Suno to come up with a country-style song about bodega cats.
After the company’s presentation, I spoke with Rausch to get more clarity on how Alexa+ will work with the rest of the online world. For one, I wanted to know for sure if that third method would work with customer service chatbots from companies like Capital One, United Airlines and more. While Rausch said that he had no details to share on specific names or services, he did confirm that “the SDK is all about integrations like that,” saying it’s for people to use Alexa to connect with agents on their behalf to complete tasks.
Rausch is aware that any friction at all in the adoption and setup process can turn people away. To that end, upgrading to Alexa+ should not require any additional sign-ins or authentication. You should be able to have all your connected appliances, security cameras and home routines carry over without any effort.
“The reason that customers love Alexa is it takes away all the complexity,” Rausch said. People don’t need to remember the brand of the WeMo plug they bought, for example, to be able to tell Alexa to turn off a lamp. “We would never take that away,” he said. When you’re adding new services after upgrading to Alexa+, Rausch said you’ll either do so “in the ways that you do it today” or that it’ll get even easier, since “Alexa can walk you through those setups in many more cases.”
Sam Rutherford for Engadget
According to Rausch, instead of having to “dig around in the Alexa app, you just say ‘Alexa, I want to set up a streaming account with Hulu’ or something.” You’ll be presented with a QR code on an Echo device with a screen to facilitate that, and the assistant should guide users along the way.
“We like to say Alexa is an expert, and now an expert on herself.”
Amazon isn’t the only company that has made its assistant perform tech support for users. This approach is very similar to how Siri can teach you how to, say, shoot a video in Cinematic mode or create a Genmoji. Where better to get help about a product you’re using than the product itself? Why make me go to a different place for information?
“From a customer experience perspective, customers just want the thing done,” Rausch said. “They don’t have to be responsible or care about any of these things, right?” He believes people just want the plumber or a reservation booked, and don’t want to fuss around with websites and phone calls.
People do want their digital assistant to be helpful and easy to use, but isn’t it equally important that these AI services are accurate and reliable?
When I asked Rausch how Amazon worked around the tendency of generative AI to hallucinate and sometimes spread misinformation, he said “I actually think in the industry, there’s been a mistake of thinking a model is a product.” He also said “LLMs are at the foundation of the architecture, but they’re not the only thing answering the question.”
In other words, Alexa+ is using a combination of Amazon’s knowledge graphs, reliable sources on the internet and partnerships with authoritative outlets. “Other products will simply give you an answer out of the LLM. If you’re asking for an authoritative answer, that’s not actually sometimes the way to get one. and I think that’s what you’re highlighting,” he said.
Rausch added that Amazon has “taken great care” with Alexa. “Will it make mistakes? Every piece of software makes mistakes,” he said. “But we’re working hard to ground it in knowledge.”
I’ve yet to try out Alexa+ for myself, and everything we’ve seen so far has been in highly controlled demos, so it’s hard to tell what real world performance will be like. But if the new Alexa is truly able to work with third-party services in a way that’s seamless and effective, it would not only bring Amazon back into the consumer AI race, but could possibly give it an advantage over the likes of Google, Apple and OpenAI. Considering Amazon really brought the idea of a virtual assistant into homes around the world, this could also have an impact that goes beyond the tech-savvy users of today’s AI services.
