An anonymous reader quotes a report from the Financial Post: A Texas power developer is proposing to repurpose nuclear reactors from Navy warships to power the United States grid as the Trump administration pushes to secure massive amounts of energy for the artificial intelligence boom. HGP Intelligent Energy LLC filed an application to the Energy Department to redirect two retired reactors to a data center project proposed at Oak Ridge, Tennessee, according to a letter submitted to the agency's Office of Energy Dominance Financing. The project, filed for the White House's Genesis Mission, would produce about 450-520 megawatts of around-the-clock electricity, or enough to power roughly 360,000 homes. The proposal would rewire reactors from naval vessels, originally built by Westinghouse Electric Company and General Electric, at a fraction of the cost of new builds.

According to the report, The developer expects to seek a loan guarantee from the U.S. Department of Energy and raise roughly $1.8-$2.1 billion in private capital to prepare the reactors for civilian use, targeting initial completion by 2029. The approach is technically feasible but would break new ground by adapting military nuclear assets for the commercial grid. Bloomberg first reported the story.

Adult children across the United States are increasingly reporting that their aging parents have developed what looks remarkably like the smartphone addiction [non-paywalled source] typically associated with teenagers, a phenomenon The Atlantic's Charlie Warzel has dubbed "phone-based retirement." A 2019 Pew Research Center study found people 60 and older spend more than half their daily leisure time -- four hours and 16 minutes -- in front of screens. Nielsen reported this year that adults 65 and up watch YouTube on their TVs nearly twice as much as they did two years ago. 40% of adults aged 59 to 77 reported feeling anxious without device access in a 2,000-person survey.

Ipsit Vahia, chief of geriatric psychiatry at Mass General Brigham's McLean Hospital, cautioned against treating all older adults as a monolithic group. The COVID-19 pandemic drove significant tech adoption among seniors as Zoom became essential for family gatherings, church services, and telehealth. Some research suggests device use may be linked to better cognitive function for people over 50, and Vahia noted that technology use in older adults appears to protect them from isolation and loneliness -- the opposite of its effect on teenagers.

Microsoft has denied any plans to rewrite Windows 11 using AI and Rust after a LinkedIn post from one of its top-level engineers sparked a wave of online backlash by claiming the company's goal was to "eliminate every line of C and C++ from Microsoft by 2030."

Galen Hunt, a principal software engineer responsible for several large-scale research projects at Microsoft, made the claim in what was originally a hiring post for his team. His original wording described a "North Star" of "1 engineer, 1 month, 1 million lines of code" and outlined a strategy to "combine AI and Algorithms to rewrite Microsoft's largest codebases." The repeated use of "our" in the post led many to interpret it as an official company direction rather than a personal research ambition.

Frank X. Shaw, Microsoft's head of communications, told Windows Latest that the company has no such plans. Hunt subsequently edited his LinkedIn post to clarify that "Windows is NOT being rewritten in Rust with AI" and that his team's work is a research project focused on building technology to enable language-to-language migration. He characterized the reaction as "speculative reading between the lines."

The Justice Department justified its delayed release of sensitive files by citing the need to carefully redact information that could identify victims, but at least some of those redactions have proven to be technically ineffective and can be bypassed by simply copying and pasting the blacked-out text into a new document.

A 2022 complaint filed by the US Virgin Islands seeking damages from Jeffrey Epstein's estate appeared on the DOJ's "Epstein Library" website with black boxes throughout. Techdirt founder Mike Masnick and others shared on Bluesky that the redactions could be trivially circumvented. The exposed text includes allegations that a co-executor signed over $400,000 in foundation checks "payable to young female models and actresses, including a former Russian model," and details about an immigration lawyer allegedly "involved in one or more forced marriages arranged among Epstein's victims."

Separately, Drop Site News was also apparently able to guess URLs of files not yet published by extrapolating the format.

An anonymous reader quotes a report from the Associated Press: The State Department announced Tuesday it was barring five Europeans it accused of leading efforts to pressure U.S. tech firms to censor or suppress American viewpoints. The Europeans, characterized by Secretary of State Marco Rubio as "radical" activists and "weaponized" nongovernmental organizations, fell afoul of a new visa policy announced in May to restrict the entry of foreigners deemed responsible for censorship of protected speech in the United States. "For far too long, ideologues in Europe have led organized efforts to coerce American platforms to punish American viewpoints they oppose," Rubio posted on X. "The Trump Administration will no longer tolerate these egregious acts of extraterritorial censorship."

The five Europeans were identified by Sarah Rogers, the under secretary of state for public diplomacy, in a series of posts on social media. [...] The five Europeans named by Rogers are: Imran Ahmed, chief executive of the Centre for Countering Digital Hate; Josephine Ballon and Anna-Lena von Hodenberg, leaders of HateAid, a German organization; Clare Melford, who runs the Global Disinformation Index; and former EU Commissioner Thierry Breton, who was responsible for digital affairs. Rogers in her post on X called Breton, a French business executive and former finance minister, the "mastermind" behind the EU's Digital Services Act, which imposes a set of strict requirements designed to keep internet users safe online. This includes flagging harmful or illegal content like hate speech. She referred to Breton warning Musk of a possible "amplification of harmful content" by broadcasting his livestream interview with Trump in August 2024 when he was running for president.

An anonymous reader quotes a report from TechCrunch: Across Uzbekistan, a network of about a hundred banks of high-resolution roadside cameras continuously scan vehicles' license plates and their occupants, sometimes thousands a day, looking for potential traffic violations. Cars running red lights, drivers not wearing their seatbelts, and unlicensed vehicles driving at night, to name a few. The driver of one of the most surveilled vehicles in the system was tracked over six months as he traveled between the eastern city of Chirchiq, through the capital Tashkent, and in the nearby settlement of Eshonguzar, often multiple times a week. We know this because the country's sprawling license plate-tracking surveillance system has been left exposed to the internet.

Security researcher Anurag Sen, who discovered the security lapse, found the license plate surveillance system exposed online without a password, allowing anyone access to the data within. It's not clear how long the surveillance system has been public, but artifacts from the system show that its database was set up in September 2024, and traffic monitoring began in mid-2025. The exposure offers a rare glimpse into how such national license plate surveillance systems work, the data they collect, and how they can be used to track the whereabouts of any one of the millions of people across an entire country. The lapse also reveals the security and privacy risks associated with the mass monitoring of vehicles and their owners, at a time when the United States is building up its nationwide array of license plate readers, many of which are provided by surveillance giant Flock.

Irish competitor Diarmuid Early, dubbed the "Lebron James of Excel spreadsheets," has won the 2025 Microsoft Excel World Championship in Las Vegas, dethroning three-time champion Andrew Ngai. The BBC reports: The esport showpiece in December attracted competitors worldwide as 256 spreadsheet heads battled it out across knockout rounds to join the final 24 in Vegas. [...] A three-time champion in the financial Excel tournaments, this win was Diarmuid's first in the overall competition. He held the triple-world champion Andrew Ngai to second place, and won the $5,000 prize and title belt. [...]

Excel esports transforms a common office tool into a dynamic sport. More than 20 years old, the competitive scene has evolved from being finance based to now involving more general problem solving. Although it might help, Diarmuid said "it doesn't require accounting or finance knowledge." He described an example where Excel is used in solving a maze, scoring poker hands, or even sorting Kings and Queens into the battles in which they fought.

Generally there is a 30 minute challenge, with each challenge broken up into levels. The questions increase gradually in difficulty, with each correct answer gaining a player points. Whoever gets the most points wins, and in a tie, it is whoever got there first. "It's just, can you think on your feet and do things quickly in Excel?" he said. "If you solve the earlier levels in a neat way, that'll let you hit the ground running faster on the later ones."

An anonymous reader quotes a report from Ars Technica: CBS cannot contain the online spread of a "60 Minutes" segment that its editor-in-chief, Bari Weiss, tried to block from airing. The episode, "Inside CECOT," featured testimonies from US deportees who were tortured or suffered physical or sexual abuse at a notorious Salvadoran prison, the Center for the Confinement of Terrorism. "Welcome to hell," one former inmate was told upon arriving, the segment reported, while also highlighting a clip of Donald Trump praising CECOT and its leadership for "great facilities, very strong facilities, and they don't play games."

Weiss controversially pulled the segment on Monday, claiming it could not air in the US because it lacked critical voices, as no Trump officials were interviewed. She claimed that the segment "did not advance the ball" and merely echoed others' reporting, NBC News reported. Her plan was to air the segment when it was "ready," insisting that holding stories "for whatever reason" happens "every day in every newsroom." But Weiss apparently did not realize that the "Inside CECOT" would still stream in Canada, giving the public a chance to view the segment as reporters had intended.

Critics accusing CBS of censoring the story quickly shared the segment online Monday after discovering that it was available on the Global TV app. Using a VPN to connect to the app with a Canadian IP address was all it took to override Weiss' block in the US, as 404 Media reported the segment was uploaded to "to a variety of file sharing sites and services, including iCloud, Mega, and as a torrent," including on the recently revived file-sharing service LimeWire. It's currently also available to stream on the Internet Archive, where one reviewer largely summed up the public's response so far, writing, "cannot believe this was pulled, not a dang thing wrong with this segment except it shows truth." "Yo what," joked Reddit user Howzitgoin, highlighting only the word "LimeWire." Another user responded, "man, who knew my nostalgia prof pic would become relevant again, WTF."

"Bringing back LimeWire to illegally rip copies of reporting suppressed by the government is definitely some cyberpunk shit," a Bluesky user wrote.

"We need a champion against the darkness," a Reddit commenter echoed. "I side with LimeWire."

An anonymous reader shares a report: It's been more than eight years since Amazon bought Whole Foods, but the two companies still haven't aligned their setup for the Microsoft software their employees use. That disconnect was flagged in an 8-week Deloitte review of Whole Foods' use of Microsoft 365 apps earlier this year, according to an internal document obtained by Business Insider. Deloitte found that Whole Foods relies on "fragmented" Microsoft toolsets, has loose security and data-retention practices, and employs a complex user-management setup -- all of which contribute to inefficiencies and lower productivity when working with Amazon employees.

The consulting firm recommended a 24-month integration plan that would first move Whole Foods' corporate employees onto Amazon's backend system, followed by its frontline workers. The phased approach would ensure a "smooth transition for users and minimal disruption to business processes," while generating cost savings, the document said. The review, completed in May, highlights Amazon's ongoing challenges in integrating Whole Foods. Since acquiring the chain in 2017, the company has struggled to scale the business and integrate operations, resulting in frequent reorganizations and shifting strategic priorities.

European public institutions are quietly migrating away from American cloud providers and office software, driven less by policy ambitions in Brussels than by the mundane legal reality that GDPR-mandated risk assessments keep flagging the US CLOUD Act as an unacceptable threat to citizen data.

Austria's Federal Ministry for Economy, Energy and Tourism moved 1,200 employees to the open-source platform Nextcloud in four months. Germany's Schleswig-Holstein has already transitioned 24,000 of its 30,000 civil servants to LibreOffice, Nextcloud and Thunderbird. The International Criminal Court in The Hague announced in November 2025 that it would replace Microsoft office software after chief prosecutor Karim Khan was temporarily locked out of his Outlook account.

Competition economist Cristina Caffarra estimates that 90% of Europe's digital infrastructure is now controlled by non-European companies. Forrester predicts no European enterprise will fully abandon US hyperscalers in 2026, but these targeted migrations for sensitive government applications are already underway.

Tech giants Google and Apple are asking some employees with H-1B visas to reconsider international travel, as their legal teams warned that visa processing delays could keep employees abroad for months, according to Business Insider. From a report: Law firms representing the tech giants sent memos advising staff who require visa stamps for reentry to stay in the U.S., warning that international travel could entangle them in visa screening delays following the introduction of a new social media screening requirement, according to the news agency. The policy subjects H-1B workers and their dependents to reviews of their social media histories.

"Please be aware that some US Embassies and Consulates are experiencing significant visa stamping appointment delays, currently reported as up to 12 months," BAL Immigration Law, which represents Google, said in a memo obtained by Business Insider. The law firm said the delays were affecting H-1B, H-4, F, J and M visas.

Uber and Lyft plan to trial robotaxis in London starting in 2026 using autonomous vehicles from Baidu, as the UK fast-tracks approvals for self-driving cars on public roads. CNBC reports: Lyft's testing of Baidu's initial fleet of dozens of vehicles will begin in 2026, pending regulatory approval, "with plans to scale to hundreds from there," Lyft CEO David Risher said in a post on social media platform X on Monday. Meanwhile, Uber said that its first pilot is expected to start in the first half of 2026. "We're excited to accelerate Britain's leadership in the future of mobility, bringing another safe and reliable travel option to Londoners next year," the company added.

The moves add to Baidu's growing global footprint, which it says includes 22 cities and more than 250,000 weekly trips, as it races against other Chinese players like WeRide and Western giants like Alphabet's Waymo. The UK, in particular, has seen a wave of interest from driverless taxi companies, following the government's announcement in June that it would accelerate its plans to allow autonomous vehicle tech on public roads. The government now aims to begin permitting robotaxis to operate in small-scale pilots starting in spring 2026, with Baidu likely aiming to be among the first. The city of London has also established a "Vision Zero" goal to eliminate all serious injuries and deaths in its transportation systems by 2041, with autonomous driving technology expected to play a large role.

"Garmin's Collier Trophy award-winning Autonomi emergency Autoland, a system designed to safely land an aircraft in the event of pilot incapacitation, made its first real-world use and save on Saturday," writes Slashdot reader slipped_bit. AvBrief.com reports: Social media posts from flight tracking hobbyists reported a King Air 200 squawked 7700 about 2 p.m. local time today. The Autoland system was initiated and landed the aircraft at Rocky Mountain Metropolitan Airport near Denver. A recording from LiveATC's feed of the airport's tower frequency includes a robotic female voice declaring a pilot incapacitation and the intention to land on Runway 30. The aircraft landed successfully and there have been no reports of injuries. The nature of the incapacitation and the condition of the pilot have not been released. VASAviation put together this nice animation of the event [here].

The aircraft, N479BR, was being operated by Buffalo River Outfitters from Aspen to Rocky Mountain Metropolitan. It's not clear how many people were on board. The system appeared to work flawlessly, and the controller at Rocky Mountain Metropolitan seemed to take it in stride, accommodating as many requests as he could before shutting down the airport for the landing.

Alphabet is acquiring Intersect for $4.75 billion to accelerate data center and power-generation capacity as AI infrastructure demand surges. CNBC reports: Alphabet said Intersect's operations will remain independent, but that the acquisition will help bring more data center and generation capacity online faster. "Intersect will help us expand capacity, operate more nimbly in building new power generation in lockstep with new data center load, and reimagine energy solutions to drive U.S. innovation and leadership," Sundar Pichai, CEO of Google and Alphabet, said in a statement.

Google already had a minority stake in Intersect from a funding round that was announced last December. In a release at the time, Intersect said its strategic partnership with Google and TPG Rise Climate aimed to develop gigawatts of data center capacity across the U.S., including a $20 billion investment in renewable power infrastructure by the end of the decade.

Alphabet said Monday that Intersect will work closely with Google's technical infrastructure team, including on the companies' co-located power site and data center in Haskell County, Texas. Google previously announced a $40 billion investment in Texas through 2027, which includes new data center campuses in the state's Haskell and Armstrong counties.

Linux's share of the desktop market has climbed to as much as 11% by one count, but that figure includes Chromebooks, and the traditional Linux desktop remains hamstrung by the same fragmentation that killed Unix decades ago. Steven J. Vaughan-Nichols, writing in The Register, argues that the proliferation of Linux desktops -- more than a dozen significant interfaces exist today, and DistroWatch lists "upwards of a hundred" -- makes it nearly impossible for ordinary users to know where to start.

Linus Torvalds has long agreed with this hypothesis. "We have way too many desktops," Vaughan-Nichols notes, summarizing Torvalds' position. The deeper issue lies in software delivery: traditional package managers like DEB and RPM "simply don't scale for the desktop," forcing distro builders to constantly rebuild programs for their specific environments. Containerized solutions like Flatpaks, Snaps and AppImages should solve this by bundling dependencies into universal packages, but the Linux community remains divided over which to adopt.

Linux Mint, for instance, refuses Snap because "Canonical has too much control over the Snap store." Hardware support further complicates this challenges, the veteran journalist writes. While Dell sells Ubuntu machines and specialist vendors like System76 and TUXEDO Computers cater to enthusiasts, "none of them make it easy" for mainstream buyers, and no major OEM strongly backs Linux. Torvalds has pointed to Chromebooks and Android as the model: Linux won on smartphones because "there's a single, unified platform with a unified way to install programs."

They call it "the business-impersonator scam". And it's fooled 396,227 Americans in just the first nine months of 2025 — 18% more than the 335,785 in the same nine months of 2024. That's according to a Bloomberg reporter (who also fell for it in late November), citing the official statistics from America's Federal Trade Commission: Some pose as airline staff on social media and respond to consumer complaints. Others use texts or e-mails claiming to be an airline reporting a delayed or cancelled flight to phish for travellers' data. But the objective is always the same: to hit a stressed out, overwhelmed traveller at their most vulnerable. In my case, the scammer exploited weaknesses in Google's automated ad-screening system, so that fraudulent sponsored results rose to the top [They'd typed "United airlines agent on demand" into Google, and the top search result on their phone said United.com, had a 1-888 number next to it and said it had had 1M+ visits in past month. "It looked legit. I tapped the number..." ]

After I reported the fake "United Airlines" ad to Google, via an online form for consumers, it was taken down. But a few days later, I entered the same search terms and the identical ad featuring the same 1-888 number was back at the top of my results. I reported it again, and it was quickly removed again... A [Google] spokesperson there said the company is constantly evolving its tactics "to stay ahead of bad actors." Of the 5.1 billion ads blocked by the company last year, she said, 415 million were taken down for "scam-related violations." Google updated its ads misrepresentation policy in 2024 to include "impersonating or falsely implying affiliation with a public figure, brand or organization to entice users to provide money or information." Still, many impostor ads slip through the cracks.
"Reported losses from business-impostor scams in the United States rose 30 per cent, to US$835 million, in the first three quarters of 2025," the article points out (citing more figures from the America's Federal Trade Commision). An updated version of the article also includes a response from United Airlines. "We encourage customers to only use customer-service contact information that is listed on our website and app."

And what happened to the scammed reporter? "I called American Express and contested the charge before cancelling my credit card. I then contacted Experian, one of the three major credit bureaus, to put a fraud alert on my file. Next, I filed a complaint with the FTC and reported the fake ad to Google.

"American Express wound up resolving the dispute in my favour, but the memories of this chaotic Thanksgiving will stay with us forever. "

"On Saturday, videos shared widely on social media showed Waymo vehicles stopped mid-intersection with hazard lights flashing, forcing other cars to maneuver around them," reports the San Francisco Chronicle.

The Independent notes that "Without working traffic lights, the driverless cars were seemingly left confused, with many halting in their tracks and causing major traffic jams. Local riders and pedestrians shared photos and videos of the vehicles stuck at intersections with long lines of drivers piling up behind them..." In some instances, several Waymos were piled up in front of a single intersection. "6 Waymos parked at a broken traffic light blocking the roads. Seems like they were not trained for a power outage," another social media user wrote.
More from CNBC: San Francisco resident Matt Schoolfield said he saw at least three Waymo autonomous vehicles stopped in traffic Saturday around 9:45 p.m. local time, including one he photographed near Arguello Boulevard and Geary Street. "They were just stopping in the middle of the street," Schoolfield said.

The power outages began around 1:09 p.m. Saturday and peaked roughly two hours later, affecting about 130,000 customers, according to Pacific Gas and Electric. As of Sunday morning, about 21,000 customers remained without power, mainly in the Presidio, the Richmond District, Golden Gate Park and parts of downtown San Francisco. PG&E said the outage was caused by a fire at a substation that resulted in "significant and extensive" damage, and said it could not yet provide a precise timeline for full restoration...

Amid the disruption, Tesla CEO Elon Musk posted on X: "Tesla Robotaxis were unaffected by the SF power outage." Unlike Waymo, Tesla does not operate a driverless robotaxi service in San Francisco. Tesla's local ride-hailing service uses vehicles equipped with "FSD (Supervised)," a premium driver assistance system. The service requires a human driver behind the wheel at all times...

The Waymo pause in San Francisco indicates cities are not yet ready for highly automated vehicles to inundate their streets, said Bryan Reimer, a research scientist at the MIT Center for Transportation and co-author of "How to Make AI Useful." "Something in the design and development of this technology was missed that clearly illustrates it was not the robust solution many would like to believe it is," he said. [He recommends "human backup systems in place around highly automated systems, including robotaxis."] State and city regulators will need to consider what the maximum penetration of highly automated vehicles should be in their region, Reimer added, and AV developers should be held responsible for "chaos gridlock," just as human drivers would be held responsible for how they drive during a blackout.

Waymo did not say when its service would resume and did not specify whether collisions involving its vehicles had occurred during the blackout.

Archive.org now has a page with "the raw analog waveform and the reconstructed digital tape image (analog.tap), read at the Computer History Museum's Shustek Research Archives on 19 December 2025 by Al Kossow using a modified tape reader and analyzed with Len Shustek's readtape tool." A Berlin-based retrocomputing enthusiast has created a page with the contents of the tape ready for bootstrapping, "including a tar file of the filesystem," and instructions on dumping an RK05 disk image from tape to disk (and what to do next).

Research professor Rob Ricci at the University of Utah's school of computing posted pictures and video of the tape-reading process, along with several updates. ("So far some of our folks think they have found Hunt The Wumpus and the C code for a Snobol interpreter.") University researcher Mike Hibler noted the code predates the famous comment "You are not expected to understand this" — and found part of the C compiler with a copyright of 1972.

The version of Unix recovered seems to have some (but not all) of the commands that later appeared in Unix v5, according to discussion on social media. "UNIX wasn't versioned as we know it today," explains University of Utah PhD student Thalia Archibald, who researched early Unix history (including the tape) and also worked on its upload. "In the early days, when you wanted to cut a tape, you'd ask Ken if it was a good day — whether the system was relatively bug-free — and copy off the research machine... I've been saying It's probably V5 minus a tiny bit, which turned out to be quite true."

"Yet another distro is making the move to the KDE Plasma desktop," writes Linux magazine.

"Parrot OS, a security-focused Linux distribution, is migrating from MATE to KDE Plasma, starting with version 7.0, now available in beta." Based on Debian 13, Parrot OS's goal is a shift toward "modernization, focusing on clearing technical debt and future-proofing the system." One big under-the-hood change is that the/tmpdirectory is now automatically mounted astmpfs(in RAM), as opposed to the physical drive. By making this change, Parrot OS enjoys improved performance and reduces wear on SSDs. This shift also means that all data in/tmpis lost during a reboot.
ParrotOS senior systems engineer Dario Camonita explains the change in a blog post, calling it "not only aesthetic, but also in terms of usability and greater consistency with our future goals..."

"While MATE will continue to be supported by us as long as upstream development continues, We have noticed and observed the continuous improvements made by the KDE team..."

And elsewhere Linux Magazine notes two other distros are embracing the desktop Enlightenment: For years, Bodhi Linux was one of the very few distributions that used anything based on Enlightenment. That period of loneliness is officially over, withMX Mokshaand AV Linux 25. MX Moksha doesn't replace the original MX Linux. Instead, it will serve as an "official spin" of the distribution...

The Enlightenment desktop (and subsequently Moksha) was developed with systemd in mind, so MX Moksha uses systemd. If you're not a fan of systemd, MX Moksha is not for you. MX Moksha is lighter than MX Linux, so it will perform better on older machines. It also uses the Liquorix kernel for lower latency. AV Linux has been released with the Xfce and LXDE desktops at different times and has only recently opted to make the switch to Enlightenment.

An anonymous reader shared this report from the Washington Post. (Alternate URL here): The American patrol satellite had the targets in its sights: two recently launched Chinese spacecraft flying through one of the most sensitive neighborhoods in space. Like any good tactical fighter, the American spacecraft, known as USA 270, approached from behind, so that the sun would be at its back, illuminating the quarry.

But then one of the Chinese satellites countered by slowing down. As USA 270 zipped by, the Chinese satellite dropped in behind its American pursuer, like Maverick's signature "hit-the-brakes" move in the movie "Top Gun." The positions reversed, U.S. officials controlling their spacecraft from Earth were forced to plot their next move. The encounter some 22,000 miles above Earth in 2022 was never acknowledged publicly by the Pentagon or Beijing. Happening out of sight and little noticed except by space and defense specialists, this kind of orbital skirmishing has become so common that defense officials now refer to it as "dogfighting..."

Much of the "dogfighting" activity in space is simply for spying, defense analysts say, with specifics largely classified — snapping photos of each other's satellites to learn what kind of systems are on board and their capabilities. They monitor the signals and data emitted by satellites, listening to communications between space and the ground. Many can even jam those signals or interfere with orbiting craft that provide missile warnings, spy or relay critical information to troops... Traditionally, once a satellite was in orbit, it largely stayed on a fixed path, its operators reluctant to burn precious fuel. But now, the Pentagon and its adversaries, notably China and Russia, are launching satellites designed to fly in more dynamic ways that resemble aircraft — banking hard, slowing down, speeding up, even flying in tandem.

"Traditionally satellites weren't designed to fight, and they weren't designed to protect themselves in a fight," said Clinton Clark, the chief growth officer of ExoAnalytic Solutions, a company that monitors activity in space. "That is all changing now."
"Unlike dogfights between fighter jets, the jockeying-for-position encounters in orbit take place over several hours, even days," the article points out.

But it also notes that recently Germany's defense minister "complained about a Russian satellite that had been flying close to a commercial communications satellite used by the German military. 'They can jam, blind, manipulate or kinetically disrupt satellites,' he said."
