"We will make the new ð algorithm...open source in 7 days," Elon Musk posted Saturday on X.com. Musk says this is "including all code used to determine what organic and advertising posts are recommended to users," and "This will be repeated every 4 weeks, with comprehensive developer notes, to help you understand what changed."

Some context from Engadget: Musk has been making promises of open-sourcing the algorithm since his takeover of Twitter, and in 2023 published the code for the site's "For You" feed on GitHub. But the code wasn't all that revealing, leaving out key details, according to analyses at the time. And it hasn't been kept up to date.
Bloomberg also reported on Saturday's announcement: The billionaire didn't say why X was making its algorithm open source. He and the company have clashed several times with regulators over content being shown to users.

Some X users had previously complained that they were receiving fewer posts on the social media platform from people they follow. In October, Musk confirmed in a post on X that the company had found a "significant bug" in the platform's "For You" algorithm and pledged a fix. The company has also been working to incorporate more artificial intelligence into its recommendation algorithm for X, using Grok, Musk's artificial intelligence chatbot...

In September, Musk wrote that the goal was for X's recommendation engine to "be purely AI" and that the company would share its open source algorithm about every two weeks. "To the degree that people are seeing improvements in their feed, it is not due to the actions of specific individuals changing heuristics, but rather increasing use of Grok and other AI tools," Musk wrote in October. The company was working to have all of the more than 100 million daily posts published to X evaluated by Grok, which would then offer individual users the posts most likely to interest them, Musk wrote. "This will profoundly improve the quality of your feed." He added that the company was planning to roll out the new features by November.

Is there a trend? This week four different articles appeared on various tech-news sites with an author bragging about switching to Linux.

"Greetings from the year of Linux on my desktop," quipped the Verge's senior reviews editor, who finally "got fed up and said screw it, I'm installing Linux."

They switched to CachyOS — just like this writer for the videogame magazine Escapist: I've had a fantastic time gaming on Linux. Valve's Windows-to-Linux translation layer, Proton, and even CachyOS' bundled fork have been working just fine. Of course, it's not perfect, and there's been a couple of instances where I've had to problem-solve something, but most of the time, any issues gaming on Linux have been fixed by swapping to another version of Proton. If you're deep in online games like Fortnite, Call of Duty, Destiny 2, GTAV or Battlefield 6, it might not be the best option to switch. These games feature anti-cheats that look for versions of Windows or even the heart of the OS, the kernel, to verify the system isn't going to mess up someone's game....

CachyOS is thankfully pre-packed with Nvidia drivers, meaning I didn't have to dance around trying to find them.... Certain titles will perform worse than their counterparts, simply due to how the bods at Nvidia are handling the drivers for Linux. This said, I'm still not complaining when I'm pushing nearly 144fps or more in newer games. The performance hit is there, but it's nowhere near enough to stave off even an attempt to mess about with Linux.

Do you know how bizarre it is to say it's "nice to have a taskbar again"? I use macOS daily for a lot of my work, which uses a design baked back in the 1990s through NeXT. Seeing just a normal taskbar that doesn't try to advertise to me or crash because an update killed it for some reason is fantastic. That's how bad it is out there right now for Windows.
"I run Artix, by the way," joked a senior tech writer at Notebookcheck (adding "There. That's out of the way...") I dual-booted a Linux partition for a few weeks. After a Windows update (that I didn't choose to do) wiped that partition and, consequently, the Linux installation, I decided to go whole-hog: I deleted Windows 11 and used the entire drive for Linux...

Artix differs from Arch in that it does not use SystemD as its init system. I won't go down the rabbit hole of init systems here, but suffice it to say that Artix boots lightning quick (less than 10 seconds from a cold power on) and is pretty light on system resources. However, it didn't come "fully assembled..." The biggest problem I ran into after installing Artix on the [MacBook] Air was the lack of wireless drivers, which meant that WiFi did not work out of the box. The resolution was simple: I needed to download the appropriate WiFi drivers (Broadcom drivers, to be exact) from Artix's main repository. This is a straightforward process handled by a single command in the Terminal, but it requires an internet connection... which my laptop did not have. Ultimately, I connected a USB-to-Ethernet adapter, plugged the laptop directly into my router, and installed the WiFi drivers that way. The whole process took about 10 minutes, but it was annoying nonetheless.

For the record, my desktop (an AMD Ryzen 7 6800H-based system) worked flawlessly out-of-the-box, even with my second monitor's uncommon resolution (1680x1050, vertical orientation). I did run into issues with installing some packages on both machines. Trying to install the KDE desktop environment (essentially a different GUI for the main OS) resulted in strange artifacts that put white text on white backgrounds in the menus, and every resolution I tried failed to correct this bug. After reverting to XFCE4 (the default desktop environment for my Artix install), the WiFi signal indicator in the taskbar disappeared. This led to me having to uninstall a network manager installed by KDE and re-linking the default network manager to the runit services startup folder. If that sentence sounds confusing, the process was much more so. It has been resolved, and I have a WiFi indicator that lets me select wireless networks again, but only after about 45 minutes of reading manuals and forum posts.

Other issues are inherent to Linux. Not all games on Steam that are deemed Linux compatible actually are. Civilization III Complete is a good example: launching the game results in the map turning completely black. (Running the game through an application called Lutris resolved this issue.) Not all the software I used on Windows is available in Linux, such as Greenshot for screenshots or uMark for watermarking photos in bulk. There are alternatives to these, but they don't have the same features or require me to relearn workflows... Linux is not a "one and done" silver bullet to solve all your computer issues. It is like any other operating system in that it will require users to learn its methods and quirks. Admittedly, it does require a little bit more technical knowledge to dive into the nitty-gritty of the OS and fully unlock its potential, but many distributions (such as Mint) are ready to go out of the box and may never require someone to open a command line...

[T]he issues I ran into on Linux were, for the most part, my fault. On Windows or macOS, most problems I run into are caused by a restriction or bug in the OS. Linux gives me the freedom to break my machine and fix it again, teaching me along the way. With Microsoft's refusal (either from pride or ignorance) to improve (or at least not crapify) Windows 11 despite loud user outrage, switching to Linux is becoming a popular option. It's one you should consider doing, and if you've been thinking about it for any length of time, it's time to dive in.
And tinkerer Kevin Wammer switched from MacOS to Linux, saying "Linux has come a long way" after more than 30 years — but "Windows still sucks..."

Yes, a federal judge blocked an attempt by Texas at an app store age-verification law. But this year Silicon Valley giants including Google and Apple "are expected to fight hard against similar legislation," reports Politico, "because of the vast legal liability it imposes on app stores and developers." In Texas, Utah and Louisiana, parent advocates have linked up with conservative "pro-family" groups to pass laws forcing mobile app stores to verify user ages and require parental sign-off. If those rules hold up in court, companies like Google and Apple, which run the two largest app stores, would face massive legal liability... California has taken a different approach, passing its own age-verification law last year that puts liability on device manufacturers instead of app stores. That model has been better received by the tech lobby, and is now competing with the app-based approach in states like Ohio. In Washington D.C., a GOP-led bill modeled off of Texas' law is wending its way through Capitol Hill. And more states are expected to join the fray, including Michigan and South Carolina.

Joel Thayer, president of the conservative Digital Progress Institute and a key architect of the Texas law, said states are only accelerating their push. He explicitly linked the age-verification debate to AI, arguing it's "terrifying" to think companies could build new AI products by scraping data from children's apps. Thayer also pointed to the Trump administration's recent executive order aimed at curbing state regulation of AI, saying it has galvanized lawmakers. "We're gonna see more states pushing this stuff," Thayer said. "What really put fuel in the fire is the AI moratorium for states. I think states have been reinvigorated to fight back on this."
He told Politico that the issue will likely be decided by America's Supreme Court, which in June upheld Texas legislation requiring age verification for online content. Thayer said states need a ruling from America's highest court to "triangulate exactly what the eff is going on with the First Amendment in the tech world.

"They're going to have to resolve the question at some point."

The Free Software Foundation's president Ian Kelling is also their senior systems administrator. This week he shared an example of how "the work we put in to making sure a program is free for us also makes it free for the rest of the world." During the COVID-19 pandemic, like everyone everywhere, the FSF increased its videoconferencing use, especially videoconferencing software that works in web browsers. We have experience hosting several different programs to accomplish this, and BigBlueButton was an important one for us for a while. It is a videoconferencing service which describes itself as a virtual classroom because of its many features designed for educational environments, such as a shared whiteboard... In BigBlueButton 2.2, the program used a freely licensed version of MongoDB, but it unintentionally picked up MongoDB's 2018 nonfree license change in versions 2.3 and 2.4. At the FSF, we noticed this [after a four-hour review] and raised the alarm with the BigBlueButton team in late 2020.

In many cases of a developer changing to a nonfree license, free forks have won out, but in this case no one judged it worth the effort to maintain a fork of the final free MongoDB version. This was a very unfortunate case for existing users of MongoDB, including the FSF, who were then faced with a challenge of maintaining their freedom by either running old and unmaintained software or switching over to a different free program. Luckily, the free software world is not especially lacking in high quality database software, and there is also a wide array of free videoconferencing software. At the FSF, we decided to spend some effort to make sure MongoDB would no longer make BigBlueButton nonfree, to help other users of MongoDB and BigBlueButton. We think BigBlueButton is really useful for free software in schools, where it is incredibly important to have free software.

On the tech team, especially when it comes to software running in a web browser, we are used to making modifications to better suit our needs. In the end, we didn't find a perfect solution, but we did find FerretDB to be a promising MongoDB alternative and assisted the developers of FerretDB to see what would be required for it to work in BigBlueButton. The BigBlueButton developers decided that some architectural level changes for their 3.0 release would be the path for them to remove MongoDB. As of BigBlueButton 3.0, released in 2025, BigBlueButton is back to being entirely free software...!

As you can see, in the world of free software, trust can be tricky, and this is part of why organizations like the FSF are so important.
Kelling notes he's part of a tech team of just two people reponsible for "63 different services, platforms, and websites for the FSF staff, the GNU Project, other community projects, and the wider free software community..."

An anonymous reader quotes a report from CBC.ca: A company largely owned by the French and U.K. governments is pitching Canada on a roughly $250-million plan to provide the military with secure satellite broadband coverage in the Arctic, CBC News has learned. Eutelsat, a rival to tech billionaire Elon Musk's Starlink, already provides some services to the Canadian military, but wants to deepen the partnership as Canada looks to diversify defence contracts away from suppliers in the United States.

A proposal for Canada's Department of National Defence to join a French Ministry of Defence initiative involving Eutelsat was apparently raised by French President Emmanuel Macron with Prime Minister Mark Carney on the sidelines of last year's G7 summit in Alberta. The prime minister's first question, according to Eutelsat and French defence officials, was how the proposal would affect the Telesat Corporation, a former Canadian Crown corporation that was privatized in the 1990s.

Telesat is in the process of developing its Lightspeed system, a Low Earth Orbit (LEO) constellation of satellites for high-speed broadband. And in mid-December, the Liberal government announced it had established a strategic partnership with Telesat and MDA Space to develop the Canadian Armed Forces' military satellite communications (MILSATCOM) capabilities. A Eutelsat official said the company already has its own satellite network in place and running, along with Canadian partners, and has been providing support to the Canadian military deployed in Latvia. "What we can provide for Canada is what we call a sovereign capacity capability where Canada would actually own all of our capacity in the Far North or wherever they require it," said David van Dyke, the general manager for Canada at Eutelsat.

"We also give them the ability to not be under the control of a singular individual who could decide to disconnect the service for political or other reasons."

An anonymous reader quotes a report from Wired: [P]erhaps AI can, in fact, learn in a more human way -- by figuring out interesting questions to ask itself and attempting to find the right answer. A project from Tsinghua University, the Beijing Institute for General Artificial Intelligence (BIGAI), and Pennsylvania State University shows that AI can learn to reason in this way by playing with computer code. The researchers devised a system called Absolute Zero Reasoner (AZR) that first uses a large language model to generate challenging but solvable Python coding problems. It then uses the same model to solve those problems before checking its work by trying to run the code. And finally, the AZR system uses successes and failures as a signal to refine the original model, augmenting its ability to both pose better problems and solve them.

The team found that their approach significantly improved the coding and reasoning skills of both 7 billion and 14 billion parameter versions of the open source language model Qwen. Impressively, the model even outperformed some models that had received human-curated data. [...] A key challenge is that for now the system only works on problems that can easily be checked, like those that involve math or coding. As the project progresses, it might be possible to use it on agentic AI tasks like browsing the web or doing office chores. This might involve having the AI model try to judge whether an agent's actions are correct. One fascinating possibility of an approach like Absolute Zero is that it could, in theory, allow models to go beyond human teaching. "Once we have that it's kind of a way to reach superintelligence," [said Zilong Zheng, a researcher at BIGAI who worked on the project].

Experts interviewed by NBC News warn that the rapid spread of AI-generated images and videos is accelerating an online trust breakdown, especially during fast-moving news events where context is scarce. From the report: President Donald Trump's Venezuela operation almost immediately spurred the spread of AI-generated images, old videos and altered photos across social media. On Wednesday, after an Immigration and Customs Enforcement officer fatally shot a woman in her car, many online circulated a fake, most likely AI-edited image of the scene that appears to be based on real video. Others used AI in attempts to digitally remove the mask of the ICE officer who shot her.

The confusion around AI content comes as many social media platforms, which pay creators for engagement, have given users incentives to recycle old photos and videos to ramp up emotion around viral news moments. The amalgam of misinformation, experts say, is creating a heightened erosion of trust online -- especially when it mixes with authentic evidence. "As we start to worry about AI, it will likely, at least in the short term, undermine our trust default -- that is, that we believe communication until we have some reason to disbelieve," said Jeff Hancock, founding director of the Stanford Social Media Lab. "That's going to be the big challenge, is that for a while people are really going to not trust things they see in digital spaces."

Though AI is the latest technology to spark concern about surging misinformation, similar trust breakdowns have cycled through history, from election misinformation in 2016 to the mass production of propaganda after the printing press was invented in the 1400s. Before AI, there was Photoshop, and before Photoshop, there were analog image manipulation techniques. Fast-moving news events are where manipulated media have the biggest effect, because they fill in for the broad lack of information, Hancock said. "In terms of just looking at an image or a video, it will essentially become impossible to detect if it's fake. I think that we're getting close to that point, if we're not already there," said Hancock. "The old sort of AI literacy ideas of 'let's just look at the number of fingers' and things like that are likely to go away."

Renee Hobbs, a professor of communication studies at the University of Rhode Island, added: "If constant doubt and anxiety about what to trust is the norm, then actually, disengagement is a logical response. It's a coping mechanism. And then when people stop caring about whether something's true or not, then the danger is not just deception, but actually it's worse than that. It's the whole collapse of even being motivated to seek truth."

An anonymous reader shares a report: Microsoft is celebrating the resurgence of interest in physical media in the only way it knows how... by halting the Windows Media Player metadata service. Readers of a certain vintage will remember inserting a CD into their PC and watching Windows Media Player populate with track listings and album artwork. No more.

Sometime before Christmas, the metadata servers stopped working and on Windows 10 or 11, the result is the same: album not found. We tried this out at Vulture Central on some sacrificial Windows devices that had media drives and can confirm that a variety of compact discs were met with stony indifference. Some 90s cheese that was successfully ripped (for personal use, of course) decades ago? No longer recognized. A reissue of something achingly hip? Also not recognized.

The abstract of a paper on NBER: School boards have statutory authority over most elementary and secondary education policies, but receive little attention compared to other actors in education systems. A fundamental challenge to understanding the importance of boards is the absence of data on the policy goals of board members -- i.e., their ideologies -- forcing researchers to conduct tests based on demographic and professional characteristics -- i.e., identities -- with which ideology is presumed to correlate.

This paper uses new data on the viewpoints and policy actions of school board members, coupled with a regression discontinuity design that generates quasi-random variation in board composition, to establish two results. The first is that the priorities of board members have large causal effects across many domains. For example, the effect of electing an equity-focused board member on test scores for low-income students is roughly equivalent to assigning every such student a teacher who is 0.3 to 0.4 SDs higher in the distribution of teacher value-added. The second is that observing policy priorities is crucial. Identity turns out to be a poor proxy for ideology, with limited governance effects that are fully explained by differences in policy priorities. Our findings challenge the belief that school boards are unimportant, showing that who serves on the board and what they prioritize can have far-reaching consequences for students.

The restaurant industry is trying to figure out whether America has hit peak pizza. From a report: Once the second-most common U.S. restaurant type, pizzerias are now outnumbered by coffee shops and Mexican food eateries, according to industry data. Sales growth at pizza restaurants has lagged behind the broader fast-food market for years, and the outlook ahead isn't much brighter.

"Pizza is disrupted right now," Ravi Thanawala, chief financial officer and North America president at Papa John's International, said in an interview. "That's what the consumer tells us." The parent of the Pieology Pizzeria chain filed for chapter 11 bankruptcy protection in December. Others, including the parent of Anthony's Coal Fired Pizza & Wings and Bertucci's Brick Oven Pizza & Pasta, earlier filed for bankruptcy.

Pizza once was a novelty outside big U.S. cities, providing room for growth for independent shops and then chains such as Pizza Hut with its red roof dine-in restaurants. Purpose-made cardboard boxes and fleets of delivery drivers helped make pizza a takeout staple for those seeking low-stress meals. Today, pizza shops are engaged in price wars with one another and other kinds of fast food. Food-delivery apps have put a wider range of cuisines and options at Americans' fingertips. And $20 a pie for a family can feel expensive compared with $5 fast-food deals, frozen pizzas or eating a home-cooked meal.

[...] Pizza's dominance in American restaurant fare is declining, however. Among different cuisines, it ranked sixth in terms of U.S. sales in 2024 among restaurant chains, down from second place during the 1990s, Technomic said. The number of pizza restaurants in the U.S. hit a record high in 2019 and has declined since then, figures from the market-research firm Datassential show.

The world's oceans absorbed yet another record-breaking amount of heat in 2025, continuing an almost unbroken streak of annual records since the start of the millennium and fueling increasingly extreme weather events around the globe. More than 90% of the heat trapped by humanity's carbon emissions ends up in the oceans, making ocean heat content one of the clearest indicators of the climate crisis's trajectory.

The analysis, published in the journal Advances in Atmospheric Sciences, drew on temperature data collected across the oceans and collated by three independent research teams. The measurements cover the top 2,000 meters of ocean depth, where most heat absorption occurs. The amount of heat absorbed is equivalent to more than 200 times the total electricity used by humans worldwide.

This extra thermal energy intensifies hurricanes and typhoons, produces heavier rainfall and greater flooding, and results in longer marine heatwaves that decimate ocean life. The oceans are likely at their hottest in at least 1,000 years and heating faster than at any point in the past 2,000 years.

YouTube is updating search filters so users can explicitly choose between Shorts and long-form videos. The change also replaces view-count sorting with a new "Popularity" filter and removes underperforming options like "Sort by Rating." The Verge reports: Right now, a filter-less search shows a mix of longform and short form videos, which can be annoying if you just want to see videos in one format or the other. But in the new search filters, among other options, you can pick to see "Videos," which in my testing has only showed a list of longform videos, or "Shorts," which just shows Shorts.

YouTube is also removing the "Upload Date - Last Hour" and "Sort by Rating" filters because they "were not working as expected and had contributed to user complaints." The company will still offer other "Upload Date" filters, like "Today," "This week," "This Month," and "This Year," and you can also find popular videos with the new "Popularity" filter, which is replacing the "View count" sort option. (With the new "Popularity" filter, YouTube says that "our systems assess a video's view count and other relevance signals, such as watch time, to determine its popularity for that specific query.")

Germany's Harz mountains, once known for their verdant spruce forests, have become a graveyard of skeletal trunks after a bark beetle outbreak ravaged the region starting in 2018 -- an infestation made possible by successive droughts and heatwaves that fatally weakened the trees. Between 2018 and 2021, Germany lost half a million hectares of forest, nearly 5% of the country's total.

Since 2010, EU land carbon absorption has declined by a third, and Germany is now almost certain to miss its carbon sequestration targets, according to Prof Matthias Dieter, head of the Thunen Institute of Forestry. "You cannot force the forest to grow -- we cannot command how much their contribution should be towards our climate targets," he said.

Foresters in the Harz are responding by abandoning monoculture plantations in favor of mixed-species approaches. Pockets of beech, firs, and sycamore are now being planted around surviving spruce. A 2018 study in Nature found tree diversity was the best protection against drought die-offs, and more recent PNAS research found that species richness protected tree growth during prolonged drought seasons. The approach marks a shift from Germany's pioneering modern forestry methods, which relied on single-species plantations now proved vulnerable to climate-driven disasters.

China has hacked the emails used by congressional staff on powerful committees in the US House of Representatives, as part of a massive cyber espionage campaign known as Salt Typhoon. An anonymous reader shares a report: Chinese intelligence accessed email systems used by some staffers [non-paywalled source] on the House China committee in addition to aides on the foreign affairs committee, intelligence committee and armed services committee, according to people familiar with the attack. The intrusions were detected in December.

The attacks are the latest element of an ongoing cyber campaign against US communication networks by the Ministry of State Security, China's intelligence service. One person familiar with the attack said it was unclear if the MSS had accessed lawmakers' emails. The MSS has been operating Salt Typhoon for several years. It allows China to access the unencrypted phone calls, texts and voicemails of almost every American, and in some cases enables access to email accounts. Salt Typhoon has also intercepted the calls of senior US officials over the past couple of years, said people familiar with the campaign.

Samsung Electronics and SK hynix are projected to raise server memory prices by up to 70% in early 2026, according to Korea Economic Daily. "Combined with 50 percent increases in 2025, this could nearly double prices by mid-2026," reports the Register. From the report: The two Korean giants, alongside US-based Micron, dominate global memory production. All three are reallocating advanced manufacturing capacity to high-margin server DRAM and HBM chips for AI infrastructure, squeezing supply for PCs and smartphones. Financial analysts have raised their earnings forecasts for the firms in response, as they look to benefit from the AI infrastructure boom that is driving up prices for everyone else. Taiwan-based market watcher TrendForce reports that conventional DRAM prices already jumped 55-60 percent in a single quarter.

Yet despite the focus on server chips, supply of these components continues to be strained too, with supplier inventories falling and shipment growth reliant on wafer output increases, according to TrendForce. As a result, it forecasts that server DRAM prices will jump by more than 60 percent in the first quarter of 2026. Prior to Christmas, analyst IDC noted the "unprecedented" memory chip shortage and warned this would have knock-on effects for both hardware makers and end users that may persist well into 2027.
