Microsoft says that some USB printers will start printing random text after installing Windows updates released since late January 2025. From a report: The known issue affects Windows 10 (version 22H2) and Windows 11 (versions 22H2 and 23H2), but according to an update to the Windows release health dashboard, the latest Windows 11 24H2 is not impacted.

"After installing the January 2025 Windows preview update (KB5050092), released January 29, 2025, or later updates, you might observe issues with USB connected dual-mode printers that support both USB Print and IPP Over USB protocols," Redmond explains. "You might observe that the printer unexpectedly prints random text and data, including network commands and unusual characters."

On affected systems, users will often see erroneously printed text that begins with the header "POST /ipp/print HTTP/1.1," followed by other IPP (Internet Printing Protocol) related issues headers. These printing issues are more frequent when the printer is turned on or reconnected after being disconnected. Affected users will observe the printer unexpectedly printing when the print spooler sends IPP protocol messages to the printer and the printer driver is installed on the Windows device.

Longtime Slashdot reader UnknowingFool writes: Gamer's Nexus performed tests on the effect of removing legacy 32-bit PhysX on the newest generation of Nvidia cards with older games, and the results are not good. With PhysX on, the latest generation Nvidia was slightly beaten by a GTX 580 (released 2010) on some games and handily beaten by a GTX 980 (2014) on some games.

With the launch of the 5000 series, NVidia dropped 32-bit CUDA support going forward. Part of that change was dropping support for 32-bit PhysX. As a result, older titles that used it would perform poorly with 5000 series cards as it would default to CPU for calculations. Even the latest CPUs do not perform as well as 15-year-old GPUs when it comes to PhysX.

The best performance on the 5080 was to turn PhysX off however that would remove many effects like smoke, breaking glass, and rubble from scenes. The second-best option was to pair a 5000 series with an older card like a 980 to handle the PhysX computations.

According to The Verge, Sonos has abandoned its plans to release a streaming video player this year. From the report: The news was announced by the company's leadership during an all-hands call today. That product, codenamed Pinewood, was set to be Sonos' next major hardware launch. It was already deep into development and has spent months in beta testing. But now the team behind it will be reassigned to other projects as interim CEO Tom Conrad reprioritizes the company's future roadmap and continues what he hopes will be a turnaround from a bruising 2024. He told employees that a push into video from Sonos is off the table "for now." [...]

Pinewood was designed to offer many of the same streaming video apps as other devices on the market along with deep universal search and content aggregation. But as I reported last month, Sonos also intended for it to double as an HDMI switcher and support passthrough functionality for gaming consoles, 4K Blu-ray players, and more. The box was also set to allow new configurations of surround sound systems using Sonos' many speakers.

An anonymous reader quotes a report from Ars Technica: On Wednesday, Google DeepMind announced two new AI models designed to control robots: Gemini Robotics and Gemini Robotics-ER. The company claims these models will help robots of many shapes and sizes understand and interact with the physical world more effectively and delicately than previous systems, paving the way for applications such as humanoid robot assistants. [...] Google's new models build upon its Gemini 2.0 large language model foundation, adding capabilities specifically for robotic applications. Gemini Robotics includes what Google calls "vision-language-action" (VLA) abilities, allowing it to process visual information, understand language commands, and generate physical movements. By contrast, Gemini Robotics-ER focuses on "embodied reasoning" with enhanced spatial understanding, letting roboticists connect it to their existing robot control systems. For example, with Gemini Robotics, you can ask a robot to "pick up the banana and put it in the basket," and it will use a camera view of the scene to recognize the banana, guiding a robotic arm to perform the action successfully. Or you might say, "fold an origami fox," and it will use its knowledge of origami and how to fold paper carefully to perform the task.

In 2023, we covered Google's RT-2, which represented a notable step toward more generalized robotic capabilities by using Internet data to help robots understand language commands and adapt to new scenarios, then doubling performance on unseen tasks compared to its predecessor. Two years later, Gemini Robotics appears to have made another substantial leap forward, not just in understanding what to do but in executing complex physical manipulations that RT-2 explicitly couldn't handle. While RT-2 was limited to repurposing physical movements it had already practiced, Gemini Robotics reportedly demonstrates significantly enhanced dexterity that enables previously impossible tasks like origami folding and packing snacks into Zip-loc bags. This shift from robots that just understand commands to robots that can perform delicate physical tasks suggests DeepMind may have started solving one of robotics' biggest challenges: getting robots to turn their "knowledge" into careful, precise movements in the real world. DeepMind claims Gemini Robotics "more than doubles performance on a comprehensive generalization benchmark compared to other state-of-the-art vision-language-action models."

Google is advancing this effort through a partnership with Apptronik to develop next-generation humanoid robots powered by Gemini 2.0. Availability timelines or specific commercial applications for the new AI models were not made available.

Roomba maker iRobot has warned it may cease operations within 12 months unless it can refinance debt or find a buyer, just one day after launching a new vacuum cleaner line. In its March 12 quarterly report, the company disclosed it had spent $3.6 million to amend terms on a $200 million Carlyle Group loan from 2023, as U.S. revenue plunged 47% in the fourth quarter.

"Given these uncertainties and the implication they may have on the Company's financials, there is substantial doubt about the Company's ability to continue as a going concern for a period of at least 12 months from the date of the issuance of its consolidated 2024 financial statements," the company wrote.

The robot vacuum pioneer has initiated a formal strategic review after a failed Amazon acquisition, the departure of founder Colin Angle, and layoffs affecting over half its workforce. iRobot cited mounting competition from Chinese manufacturers and expects continued losses for "the foreseeable future."

Amazon, Alphabet's Google and Meta Platforms on Wednesday said they support efforts to at least triple nuclear energy worldwide by 2050. From a report: The tech companies signed a pledge first adopted in December 2023 by more than 20 countries, including the U.S., at the U.N. Climate Change Conference. Financial institutions including Bank of America, Goldman Sachs and Morgan Stanley backed the pledge last year.

The pledge is nonbinding, but highlights the growing support for expanding nuclear power among leading industries, finance and governments. Amazon, Google and Meta are increasingly important drivers of energy demand in the U.S. as they build out AI centers. The tech sector is turning to nuclear power after concluding that renewables alone won't provide enough reliable power for their energy needs. Microsoft and Apple did not sign the statement.

AmiMoJo shares a report from Electrek: The U.S. installed 50 gigawatts (GW) of new solar capacity in 2024, the largest single year of new capacity added to the grid by any energy technology in over two decades. That's enough to power 8.5 million households. According to the U.S. Solar Market Insight 2024 Year in Review report (PDF) released today by the Solar Energy Industries Association (SEIA) and Wood Mackenzie, solar and storage account for 84% of all new electric generating capacity added to the grid last year.

In addition to historic deployment, surging U.S. solar manufacturing emerged as a landmark economic story in 2024. Domestic solar module production tripled last year, and at full capacity, U.S. factories can now produce enough to meet nearly all demand for solar panels in the U.S. Solar cell manufacturing also resumed in 2024, strengthening the U.S. energy supply chain. [...] Total US solar capacity is expected to reach 739 GW by 2035, but the report forecasts include scenarios showing how policy changes could impact the solar market. [...] The low case forecast shows a 130 GW decline in solar deployment over the next decade compared to the base case, representing nearly $250 billion of lost investment.

An anonymous reader quotes a report from TechCrunch: There's a power crunch looming as AI and cloud providers ramp up data center construction. But a new report suggests that a solution lies beneath their foundations. Advanced geothermal power could supply nearly two-thirds of new data center demand by 2030, according to an analysis by the Rhodium Group. The additions would quadruple the amount of geothermal power capacity in the U.S. -- from 4 gigawatts to about 16 gigawatts -- while costing the same or less than what data center operators pay today. In the western U.S., where geothermal resources are more plentiful, the technology could provide 100% of new data center demand. Phoenix, for example, could add 3.8 gigawatts of data center capacity without building a single new conventional power plant.

Geothermal resources have enormous potential to provide consistent power. Historically, geothermal power plants have been limited to places where Earth's heat seeps close to the surface. But advanced geothermal techniques could unlock 90 gigawatts of clean power in the U.S. alone, according to the U.S. Department of Energy. [...] Because geothermal power has very low running costs, its price is competitive with data centers' energy costs today, the Rhodium report said. When data centers are sited similarly to how they are today, a process that typically takes into account proximity to fiber optics and major metro areas, geothermal power costs just over $75 per megawatt hour. But when developers account for geothermal potential in their siting, the costs drop significantly, down to around $50 per megawatt hour.

The report assumes that new generating capacity would be "behind the meter," which is what experts call power plants that are hooked up directly to a customer, bypassing the grid. Wait times for new power plants to connect to the grid can stretch on for years. As a result, behind the meter arrangements have become more appealing for data center operators who are scrambling to build new capacity.

MojoKid writes: AMD just launched its latest flagship desktop processors, the Ryzen 9 9950X3D. Ryzen 9 9950X3D is a 16-core/32-thread, dual-CCD part with a base clock of 4.3GHz and a max boost clock of 5.7GHz. There's also 96MB of second-gen 3D V-Cache on board. Standard Ryzen 9000 series processors feature 32MB of L3 cache per compute die, but with the Ryzen 9 9950X3D, one compute die is outfitted with an additional 96MB of 3D V-Cache, bringing the total L3 up to 128MB (144MB total cache). The CCD outfitted with 3D V-Cache operates at more conservative voltages and frequencies, but the bare compute die is unencumbered.

The Ryzen 9 9950X3D turns out to be a high-performance, no-compromise desktop processor. Its complement of 3D V-Cache provides tangible benefits in gaming, and AMD's continued work on the platform's firmware and driver software ensures that even with the Ryzen 9 9950X3D's asymmetrical CCD configuration, performance is strong across the board. At $699, it's not cheap but its a great CPU for gaming and content creation, and one of the most powerful standard desktop CPUs money can buy currently.

An anonymous reader quotes a report from Ars Technica: HP, along with other printer brands, is infamous for issuing firmware updates that brick already-purchased printers that have tried to use third-party ink. In a new form of frustration, HP is now being accused of issuing a firmware update that broke customers' laser printers -- even though the devices are loaded with HP-brand toner. The firmware update in question is version 20250209, which HP issued on March 4 for its LaserJet MFP M232-M237 models. Per HP, the update includes "security updates," a "regulatory requirement update," "general improvements and bug fixes," and fixes for IPP Everywhere. Looking back to older updates' fixes and changes, which the new update includes, doesn't reveal anything out of the ordinary. The older updates mention things like "fixed print quality to ensure borders are not cropped for certain document types," and "improved firmware update and cartridge rejection experiences." But there's no mention of changes to how the printers use or read toner.

However, users have been reporting sudden problems using HP-brand toner in their M232-M237 series printers since their devices updated to 20250209. Users on HP's support forum say they see Error Code 11 and the hardware's toner light flashing when trying to print. Some said they've cleaned the contacts and reinstalled their toner but still can't print. "Insanely frustrating because it's my small business printer and just stopped working out of nowhere[,] and I even replaced the tone[r,] which was a $60 expense," a forum user wrote on March 8. HP said in a statement: "We are aware of a firmware issue affecting a limited number of HP LaserJet 200 Series devices and our team is actively working on a solution. For assistance, affected customers can contact our support team at: https://support.hp.com." It's unclear how widespread the problems are.

Adafruit Industries used large language model (LLM) tool Claude Code to streamline hardware development, writes managing director ptorrone.

In a demo video Limor 'Ladyada' Fried compares the LLM's command-line interface to working with the build-automation tool CMake or "a weird cross between IRC and a BBS." The first step was converting a PDF of the hardware's datasheet into text, and Claude Code first displays the appropriate Bash command, while asking "Do you want to proceed?" ("What's nice is that it doesn't make changes, even though it has write access to files in the directory...") Eventually from the data sheet it creates things like an accurate register map, C++ headers, and even license text — and more.

"We are using it to automate parts of the coding and debugging process for an Arduino-compatible Metro Mini board with an OPT 4048 color sensor," writes ptorrone: Using Claude Code's shell access, we can compile, upload, and test code in a semi-automated workflow, allowing the LLM to suggest fixes for errors along the way... While the AI isn't perfect for high-level driver development, it's proving VERY useful for tedious debugging and super-fast iterative improvements, bringing hardware automation closer to ...reality.
In the video Fried describes it like this. "I have a full debugging cycle, where I'm there — I'm like driving the car — but I have this copilot that's telling me where to go..."

"I feel like I'm getting closer to having a semi-automated way of doing driver development."

"The ubiquitous ESP32 microchip made by Chinese manufacturer Espressif and used by over 1 billion units as of 2023 contains an undocumented 'backdoor' that could be leveraged for attacks," writes BleepingComputer.

"The undocumented commands allow spoofing of trusted devices, unauthorized data access, pivoting to other devices on the network, and potentially establishing long-term persistence." This was discovered by Spanish researchers Miguel Tarascó Acuña and Antonio Vázquez Blanco of Tarlogic Security, who presented their findings yesterday at RootedCON in Madrid. "Tarlogic Security has detected a backdoor in the ESP32, a microcontroller that enables WiFi and Bluetooth connection and is present in millions of mass-market IoT devices," reads a Tarlogic announcement shared with BleepingComputer. "Exploitation of this backdoor would allow hostile actors to conduct impersonation attacks and permanently infect sensitive devices such as mobile phones, computers, smart locks or medical equipment by bypassing code audit controls...."

Tarlogic developed a new C-based USB Bluetooth driver that is hardware-independent and cross-platform, allowing direct access to the hardware without relying on OS-specific APIs. Armed with this new tool, which enables raw access to Bluetooth traffic, Targolic discovered hidden vendor-specific commands (Opcode 0x3F) in the ESP32 Bluetooth firmware that allow low-level control over Bluetooth functions. In total, they found 29 undocumented commands, collectively characterized as a "backdoor," that could be used for memory manipulation (read/write RAM and Flash), MAC address spoofing (device impersonation), and LMP/LLCP packet injection.

Espressif has not publicly documented these commands, so either they weren't meant to be accessible, or they were left in by mistake.

An anonymous reader quotes a report from Ars Technica: On Thursday, music labels sought to add nearly 500 more sound recordings to a lawsuit accusing the Internet Archive (IA) of mass copyright infringement through its Great 78 Project, which seeks to digitize all 3 million three-minute recordings published on 78 revolutions-per-minute (RPM) records from about 1898 to the 1950s. If the labels' proposed second amended complaint is accepted by the court, damages sought in the case -- which some already feared could financially ruin IA and shut it down for good -- could increase to almost $700 million. (Initially, the labels sought about $400 million in damages.) IA did not respond to Ars' request for comment, but the filing noted that IA has not consented to music labels' motion to amend their complaint. [...]

Some sound recording archivists and historians also continue to defend the Great 78 Project as a critical digitization effort at a time when quality of physical 78 RPM records is degrading and the records themselves are becoming obsolete, with very few libraries even maintaining equipment to play back the limited collections that are available in physical archives. They push back on labels' claims that commercially available Spotify streams are comparable to the Great 78 Project's digitized recordings, insisting that sound history can be lost when obscure recordings are controlled by rights holders who don't make them commercially available. [...] David Seubert, who manages sound collections at the University of California, Santa Barbara library, told Ars that he frequently used the project as an archive and not just to listen to the recordings.

For Seubert, the videos that IA records of the 78 RPM albums capture more than audio of a certain era. Researchers like him want to look at the label, check out the copyright information, and note the catalogue numbers, he said. "It has all this information there," Seubert said. "I don't even necessarily need to hear it," he continued, adding, "just seeing the physicality of it, it's like, 'Okay, now I know more about this record.'" [...] Nathan Georgitis, the executive director of the Association for Recorded Sound Collections (ARSC), told Ars that you just don't see 78 RPM records out in the world anymore. Even in record stores selling used vinyl, these recordings will be hidden "in a few boxes under the table behind the tablecloth," Georgitis suggested. And in "many" cases, "the problem for libraries and archives is that those recordings aren't necessarily commercially available for re-release."

That "means that those recordings, those artists, the repertoire, the recorded sound history in itself -- meaning the labels, the producers, the printings -- all of that history kind of gets obscured from view," Georgitis said. Currently, libraries trying to preserve this history must control access to audio collections, Georgitis said. He sees IA's work with the Great 78 Project as a legitimate archive in that, unlike a streaming service, where content may be inconsistently available, IA's "mission is to preserve and provide access to content over time." "That 'over time' part is really the key function, I think, that distinguishes an archive from maybe a streaming service in a way," Georgitis said. "The Internet Archive is not hurting the revenue of the recording industry at all," Seubert suggested. "It has no impact on their revenue." Instead, he suspects that labels' lawsuit is "somehow vindictive," because the labels perhaps "don't like the Internet Archive's way of pushing the envelope on copyright and fair use."

"There are people who, like the founder of the Internet Archive, want to push that envelope, and the media conglomerates want to push back in the other direction," Seubert said.

Warner Bros. Home Entertainment has confirmed widespread issues affecting DVDs manufactured between 2006-2008 that are experiencing premature disc rot. The company is offering replacements for affected titles but no refunds, even when replacements aren't possible.

The problem manifests in various ways: complete disc failure, freezing midway through playback, or menu issues. Movie critic Chris Bumbray recently discovered several of his classic film DVDs had deteriorated, including titles not available digitally. DVD collectors have documented this issue for years via YouTube and forums, with speculation that a Pennsylvania manufacturing plant used subpar materials.

Brother has rejected claims that its firmware updates intentionally disable printer functionality when third-party cartridges are installed. The controversy emerged after a YouTube video by Louis Rossman, which has garnered over 160,000 views, alleged the company had joined competitors in anti-consumer practices. The allegations stem from online reports, including a 2022 Reddit post claiming firmware update W1.56 disabled automatic color registration on a Brother MFC-3750 using non-Brother toner, rendering it "effectively non-functional."

In a statement to Ars Technica, Brother explicitly denied these accusations: "Please be assured that Brother firmware updates do not block the use of third-party ink in our machines." The company said it recommends genuine supplies for "optimal performance" and performs a "Brother Genuine check" during troubleshooting, which may have caused "misunderstanding."
