☕️ Fin de la 3G chez Free Mobile : près de 15 000 sites en moins dans les 900 MHz

En octobre, quelques jours après la validation par l’Arcep d’une nouvelle prolongation de l’itinérance 2G et 3G de Free sur le réseau d’Orange, Free Mobile annonçait la fin de sa 3G. Désormais, la fiche d’information standardisée indique : « Service accessible en itinérance 2G/3G sur le réseau de l’opérateur historique partenaire ».

Au 1ᵉʳ décembre 2025 (relevé sur le mois de novembre), Free disposait encore de 21 137 sites en service dans les 900 MHz, ainsi que 181 sites dans les 2100 MHz. Au 1ᵉʳ janvier 2026, la situation a bien changé : 6 303 sites 3G en service dans les 900 MHz, 0 dans les 2 100 MHz.

Free a donc perdu près de 15 000 sites en service dans les 900 MHz en 3G… mais en gagne dans le même temps plus de 11 000 en 4G, toujours dans les 900 MHz. La 3G dans les 900 MHz chez les trois autres opérateurs ne change que peu avec ± une centaine de sites maximum.

C’est le seul opérateur sur le mois de décembre à annoncer des changements sur cette bande de fréquence pour la 4G. Les trois autres ne laisseront pour rappel la 3G de côté qu’à partir de 2028, ils continuent donc d’assurer un service à leurs clients d’ici là.

En janvier, Free est d’ailleurs toujours le seul opérateur avec des sites 4G en service dans les 900 MHz, avec désormais près de 24 000 sites (pour un peu plus de 26 000 autorisations). Orange a quatre autorisations, mais aucune mise en service.

CES 2026 : coup d'oeil chez BIWIN avec le très séduisant Mini SSD

Le Mini SSD de BIWIN ne nous est pas inconnu, mais nous ne l'avions jamais vu en vrai, et nous n'�tions pas au fait de son d�veloppement. Bien que d�voil� initialement par GPD pour la console WIN MAX 5, puis repris par ONEXPLAYER ensuite, le Mini SSD CL100 est un produit 100 % BIWIN, qui a tout simplement cherch� des partenaires apr�s le d�veloppement. Et bonne nouvelle, d'autres marques devraient rejoindre le mouvement. Sur le papier, le principe est tr�s simple : proposer une solution de stockage performante et facile � remplacer. Point de d�montage de machine ici, le SSD reprend la forme, dans les grandes lignes, d'une carte SD et s'installe via un tiroir comme une carte SIM, du moins chez GPD. On peut donc ais�ment imaginer des machines avec une m�moire interne pour un peu plus que le stockage, et � c�t� plusieurs SSD pour basculer entre les jeux et applications. […]

How Long Does It Take to Fix Linux Kernel Bugs?

An anonymous reader shared this report from It's FOSS: Jenny Guanni Qu, a researcher at [VC fund] Pebblebed, analyzed 125,183 bugs from 20 years of Linux kernel development history (on Git). The findings show that the average bug takes 2.1 years to find. [Though the median is 0.7 years, with the average possibly skewed by "outliers" discovered after years of hiding.] The longest-lived bug, a buffer overflow in networking code, went unnoticed for 20.7 years! [But 86.5% of bugs are found within five years.] The research was carried out by relying on the Fixes: tag that is used in kernel development. Basically, when a commit fixes a bug, it includes a tag pointing to the commit that introduced the bug. Jenny wrote a tool that extracted these tags from the kernel's git history going back to 2005. The tool finds all fixing commits, extracts the referenced commit hash, pulls dates from both commits, and calculates the time frame. As for the dataset, it includes over 125k records from Linux 6.19-rc3, covering bugs from April 2005 to January 2026. Out of these, 119,449 were unique fixing commits from 9,159 different authors, and only 158 bugs had CVE IDs assigned. It took six hours to assemble the dataset, according to the blog post, which concludes that the percentage of bugs found within one year has improved dramatically, from 0% in 2010 to 69% by 2022. The blog post says this can likely be attributed to: The Syzkaller fuzzer (released in 2015) Dynamic memory error detectors like KASAN, KMSAN, KCSAN sanitizers Better static analysis More contributors reviewing code But "We're simultaneously catching new bugs faster AND slowly working through ~5,400 ancient bugs that have been hiding for over 5 years." They've also developed an AI model called VulnBERT that predicts whether a commit introduces a vulnerability, claiming that of all actual bug-introducing commits, it catches 92.2%. "The goal isn't to replace human reviewers but to point them at the 10% of commits most likely to be problematic, so they can focus attention where it matters..."

Amazon's AI Tool Listed Products from Small Businesses Without Their Knowledge

Bloomberg reports on Amazon listings "automatically generated by an experimental AI tool" for stores that don't sell on Amazon. Bloomberg notes that the listings "didn't always correspond to the correct product", leaving the stores to handle the complaints from angry customers: Between the Christmas and New Year holidays, small shop owners and artisans who had found their products listed on Amazon took to social media to compare notes and warn their peers... In interviews, six small shop owners said they found themselves unwittingly selling their products on Amazon's digital marketplace. Some, especially those who deliberately avoided Amazon, said they should have been asked for their consent. Others said it was ironic that Amazon was scouring the web for products with AI tools despite suing Perplexity AI Inc.for using similar technology to buy products on Amazon... Some retailers say the listings displayed the wrong product image or mistakenly showed wholesale pricing. Users of Shopify Inc.'s e-commerce tools said the system flagged Amazon's automated purchases as potentially fraudulent... In a statement, Amazon spokesperson Maxine Tagay said sellers are free to opt out. Two Amazon initiatives — Shop Direct, which links out to make purchases on other retailers' sites, and Buy For Me, which duplicates listings and handles purchases without leaving Amazon — "are programs we're testing that help customers discover brands and products not currently sold in Amazon's store, while helping businessesâreach new customers and drive incremental sales," she said in an emailed statement. "We have received positive feedback on these programs." Tagay didn't say why the sellers were enrolled without notifying them. She added that the Buy For Me selection features more than 500,000 items, up from about 65,000 at launch in April. The article includes quotes from the owners of affected businesses. A one-person company complained that "If suddenly there were 100 orders, I couldn't necessarily manage. When someone takes your proprietary, copyrighted works, I should be asked about that. This is my business. It's not their business." One business owner said "I just don't want my products on there... It's like if Airbnb showed up and tried to put your house on the market without your permission." One business owner complained "When things started to go wrong, there was no system set up by Amazon to resolve it. It's just 'We set this up for you, you should be grateful, you fix it.'" One Amazon representative even suggested they try opening a $39-a-month Amazon seller account.

Finnish Startup IXI Plans New Autofocusing Eyeglasses

An anonymous reader shared this report from CNET: Finland-based IXI Eyewear has raised more than $40 million from investors, including Amazon, to build glasses with adaptive lenses that could dynamically autofocus based on where the person wearing them is looking. In late 2025, the company said it had developed a glasses prototype that weighs just 22 grams. It includes embedded sensors aimed at the wearer's eyes and liquid crystal lenses that respond accordingly. According to the company, the autofocus is "powered by technology hidden within the frame that tracks eye movements and adjusts focus instantly — whether you're looking near or far..." iXI told CNN in a story published on Tuesday that it expects to launch its glasses within the next year. It has a waitlist for the glasses on its website, but has not said in what regions they'll be available... This type of technology is also being pursued by Japanese startups Elcyo and Vixion. Vixion already has a product with adaptive lenses embedded in the middle of the lenses (they do not resemble standard glasses). CNET spoke to optometrist Meenal Agarwal, who pointed out that besides startup efforts, there have also been research prototypes like Stanford's autofocal glasses. "But none have consumer-ready, lightweight glasses in the market yet." CNN reports on the 75-person company's product, noting that "By using a dynamic lens, IXI does away with fixed magnification areas." "Modern varifocals have this narrow viewing channel because they're mixing basically three different lenses," said Niko Eiden, CEO of IXI... So, there are areas of distortion, the sides of the lenses are quite useless for the user, and then you really have to manage which part of this viewing channel you're looking at." The IXI glasses, Eiden said, will have a much larger "reading" area for close-up vision — although still not as large as the entire lens — and it will also be positioned "in a more optimal place," based on the user's standard eye exam. But the biggest plus, Eiden added, is that most of the time, the reading area simply disappears, leaving the main prescription for long distance on the entire lens. "For seeing far, the difference is really striking, because with varifocals you have to look at the top part of the lens in order to see far. With ours, you have the full lens area to see far..." The new glasses won't come without drawbacks, Eiden admits: "This will be yet another product that you need to charge," he said. Although the charging port is magnetic and cleverly hidden in the temple area, overnight charging will be required... Another limitation is that more testing is required to make the glasses safe for driving, Eiden said, adding that in case of a malfunction of the electronics or the liquid crystal area, the glasses are equipped with a failsafe mode that shuts them down to the base state of the main lens, which would usually be distance vision, without creating any visual disturbances.

Nvidia CEO Jensen Huang Says AI Doomerism Has 'Done a Lot of Damage'

Nvidia CEO Jensen Huang "said one of his biggest takeaways from 2025 was 'the battle of narratives' over the future of AI development between those who see doom on the horizon and the optimists," reports Business Insider. Huang did acknowledge that "it's too simplistic" to entirely dismiss either side (on a recent episode of the "No Priors" podcast). But "I think we've done a lot of damage with very well-respected people who have painted a doomer narrative, end of the world narrative, science fiction narrative." "It's not helpful to people. It's not helpful to the industry. It's not helpful to society. It's not helpful to the governments..." [H]e cited concerns about "regulatory capture," arguing that no company should approach governments to request more regulation. "Their intentions are clearly deeply conflicted, and their intentions are clearly not completely in the best interest of society," he said. "I mean, they're obviously CEOs, they're obviously companies, and obviously they're advocating for themselves..." "When 90% of the messaging is all around the end of the world and the pessimism, and I think we're scaring people from making the investments in AI that makes it safer, more functional, more productive, and more useful to society," he said. Elsewhere in the podcast, Huang argues that the AI bubble is a myth. Business Insider adds that "a spokesperson for Nvidia declined to elaborate on Huang's remarks."

How Many Years Left Until the Hubble Space Telescope Reenters Earth's Atmosphere?

"The clock is ticking" on the Hubble Space Telescope, writes the space news site Daily Galaxy, citing estimates from the unofficial "Hubble Reentry Tracker" site (which uses orbital data from the site space-track.org, created by tech integrator SAIC): While Hubble was initially launched into low Earth orbit at an altitude of around 360 miles, it has since descended to approximately 326 miles, and it continues to fall... "The solar flux levels are currently longer in duration and more elevated than previously anticipated, resulting in an earlier reentry forecast for the Hubble Space Telescope if no reboost mission is conducted," Hubble Reentry Trackersays the Hubble Reentry Tracker... ["Hubble has been reboosted three times in its history," the site points out, "all by servicing missions using the Space Shuttle."] NASA partnered with SpaceX in 2022 to explore the feasibility of raising Hubble to its original altitude of 373 miles. Such an adjustment would have bought Hubble a few more years in orbit. However, the future of this plan remains uncertain, as NASA has not made any official announcements to move forward with it... Solar flux levels, which determine atmospheric drag, have increased in recent years, accelerating the telescope's decline. This change in solar behavior means that the possibility of Hubble reentering Earth's atmosphere in the next five to six years is quite high if no corrective action is taken. ["But it is difficult to estimate this value due to the variability of future solar flux," the site cautions. "In the best case, Hubble may not reenter for 15 more years, around 2040. In the worst case, it could reenter in 4 years..."] Once Hubble reaches an altitude of 248 miles, it is expected that it will have less than a year before reentry... While Hubble's end may be near, there is a promising new project on the horizon: Lazuli, a privately-funded space telescope funded by former Google CEO Eric Schmidt. Lazuli aims to become the first privately-funded space telescope, and it could be the successor Hubble enthusiasts have been hoping for. Schmidt Sciences, the organization behind the telescope, plans to launch Lazuli by 2028, providing a more modern alternative to Hubble with a larger mirror and enhanced capabilities. The telescope's proposed design includes a 94-inch-wide mirror, which is a significant upgrade from Hubble's 94.5-inch mirror, and will feature updated instruments to capture more detailed data than ever before.

Walmart Announces Drone Delivery, Integration with Google's AI Chatbot Gemini

Alphabet-owned Wing "is expanding its drone delivery service to an additional 150 Walmart stores across the U.S.," reports Axios: [T]he future is already here if you live in Dallas — where some Walmart customers order delivery by Wing three times a week. By the end of 2026, some 40 million Americans, or about 12 percent of the U.S. population, will be able to take advantage of the convenience, the companies claim... Once the items are picked and packed in a small cardboard basket, they are loaded onto a drone inside a fenced area in the Walmart parking lot. Drones fly autonomously to the designated address, with human pilots monitoring each flight from a central operations hub.... For now, Wing deliveries are free. "The goal is to expose folks to the wonders of drone delivery," explains Wing's chief business officer, Heather Rivera... Over time, she said Wing expects delivery fees to be comparable to other delivery options, but faster and more convenient. Service began recently in Atlanta and Charlotte, and it's coming soon to Los Angeles, Houston, Cincinnati, St. Louis, Miami and other major U.S. cities to be announced later, according to the article. "By 2027, Walmart and Wing say they'll have a network of more than 270 drone delivery locations nationwide." Walmart also announced a new deal today with Google's Gemini, allowing customers to purchase Walmart products from within Gemini. (Walmart announced a similar deal for ChatGPT in October.) Slashdot reader BrianFagioli calls this "a defensive angle that Walmart does not quite say out loud." As AI models answer more questions directly, retailers risk losing customers before they ever hit a website. If Gemini recommends a product from someone else first, Walmart loses the sale before it starts. By planting itself inside the AI, Walmart keeps a seat at the table while the internet shifts under everyone's feet. Google clearly benefits too. Gemini gets a more functional purpose than just telling you how to boil pasta or summarize recipes. Now it can carry someone from the moment they wonder what they need to the moment the order is placed. That makes the assistant stickier and a bit more practical than generic chat. Walmart's incoming CEO John Furner says the company wants to shape this new pattern instead of being dragged into it later. Sundar Pichai calls Walmart an early partner in what he sees as a broader wave of agent style commerce, where AI starts doing the errands people used to handle themselves. The article concludes "This partnership serves as a snapshot of where retail seems to be heading..."

Gentoo Linux Plans Migration from GitHub Over 'Attempts to Force Copilot Usage for Our Repositories'

Gentoo Linux posted its 2025 project retrospective this week. Some interesting details: Mostly because of the continuous attempts to force Copilot usage for our repositories, Gentoo currently considers and plans the migration of our repository mirrors and pull request contributions to Codeberg. Codeberg is a site based on Forgejo, maintained by a non-profit organization, and located in Berlin, Germany. Gentoo continues to host its own primary git, bugs, etc infrastructure and has no plans to change that... We now publish weekly Gentoo images for Windows Subsystem for Linux (WSL), based on the amd64 stages, see our mirrors. While these images are not present in the Microsoft store yet, that's something we intend to fix soon... Given the unfortunate fracturing of the GnuPG / OpenPGP / LibrePGP ecosystem due to competing standards, we now provide an alternatives mechanism to choose the system gpg provider and ease compatibility testing... We have added a bootstrap path for Rust from C++ using Mutabah's Rust compiler mrustc, which alleviates the need for pre-built binaries and makes it significantly easier to support more configurations. Similarly, Ada and D support in gcc now have clean bootstrap paths, which makes enabling these in the compiler as easy as switching the useflags on gcc and running emerge. Other interesting statistics for the year: Gentoo currently consists of 31,663 ebuilds for 19,174 different packages.For amd64 (x86-64), there are 89 GBytes of binary packages available on the mirrors.Gentoo each week builds 154 distinct installation stages for different processor architectures and system configurations, with an overwhelming part of these fully up-to-date.The number of commits to the main ::gentoo repository has remained at an overall high level in 2025, with a slight decrease from 123,942 to 112,927.The number of commits by external contributors was 9,396, now across 377 unique external authors.

Personal Info on 17.5 Million Users May Have Leaked to Dark Web After 2024 Instagram Breach

An anonymous reader shared this report from Engadget: If you received a bunch of password reset requests from Instagram recently, you're not alone. As reported by Malwarebytes, an antivirus software company, there was a data breach revealing the "sensitive information" of 17.5 million Instagram users. Malwarebytes added that the leak included Instagram usernames, physical addresses, phone numbers, email addresses and more. The company added that the "data is available for sale on the dark web and can be abused by cybercriminals." Malwarebytes noted in an email to its customers that it discovered the breach during its routine dark web scan and that it's tied to a potential incident related to an Instagram API exposure from 2024.

China Tests a Supercritical CO2 Generator in Commercial Operation

"China recently placed a supercritical carbon dioxide power generator into commercial operation," writes CleanTechnica, "and the announcement was widely framed as a technological breakthrough." The system, referred to as Chaotan One, is installed at a steel plant in Guizhou province in mountainous southwest China and is designed to recover industrial waste heat and convert it into electricity. Each unit is reported to be rated at roughly 15 MW, with public statements describing configurations totaling around 30 MW. Claimed efficiency improvements range from 20% to more than 30% higher heat to power conversion compared with conventional steam based waste heat recovery systems. These are big numbers, typical of claims for this type of generator, and they deserve serious attention. China doing something first, however, has never been a reliable indicator that the thing will prove durable, economic, or widely replicable. China is large enough to try almost everything. It routinely builds first of a kind systems precisely because it can afford to learn by doing, discarding what does not work and scaling what does. This approach is often described inside China as crossing the river by feeling for stones. It produces valuable learning, but it also produces many dead ends. The question raised by the supercritical CO2 deployment is not whether China is capable of building it, but whether the technology is likely to hold up under real operating conditions for long enough to justify broad adoption. A more skeptical reading is warranted because Western advocates of specific technologies routinely point to China's limited deployments as evidence that their preferred technologies are viable, when the scale of those deployments actually argues the opposite. China has built a single small modular reactor and a single experimental molten salt reactor, not fleets of them, despite having the capital, supply chains, and regulatory capacity to do so if they made economic sense... If small modular reactors or hydrogen transportation actually worked at scale and cost, China would already be building many more of them, and the fact that it is not should be taken seriously rather than pointing to very small numbers of trials compared to China's very large denominators... What is notably absent from publicly available information is detailed disclosure of materials, operating margins, impurity controls, and maintenance assumptions. This is not unusual for early commercial deployments in China. It does mean that external observers cannot independently assess long term durability claims. The article notes America's Energy Department funded a carbon dioxide turbine in Texas rated at roughly 10 MW electric that "reached initial power generation in 2024 after several years of construction and commissioning." But for both these efforts, the article warns that "early efficiency claims should be treated as provisional. A system that starts at 15 MW and delivers 13 MW after several years with rising maintenance costs is not a breakthrough. It is an expensive way to recover waste heat compared with mature steam based alternatives that already operate for decades with predictable degradation..." "If both the Chinese and U.S. installations run for five years without significant reductions in performance and without high maintenance costs, I will be surprised. In that case, it would be worth revisiting this assessment and potentially changing my mind." Thanks to long-time Slashdot reader cusco for sharing the article.
