Russian Cable Attacks 'Threaten To Cut Off World's Internet' (telegraph.co.uk) 123

Military chiefs at Nato have been warned of global internet blackouts following a string of suspected Russian attacks on subsea cables. From a report: Telecoms companies including Vodafone, O2 owner Telefonica and Orange have written to UK, EU and Nato officials warning that a rise in sabotage incidents was putting critical services at risk. In an open letter, they wrote: "The repercussions of damage to subsea cables extend far beyond Europe, potentially affecting global internet and power infrastructure, international communications, financial transactions and critical services worldwide."

It comes after a spike in incidents relating to fibre optic cables on seabeds that carry huge volumes of data, voice and internet traffic between countries. More than 500 cables carry around 95pc of all international data, while their remote location makes them difficult and costly to monitor. At least 11 subsea cables have been damaged in the Baltic Sea since October 2023 and similar outages have been reported in the North Sea.

The incidents have fuelled fears of sabotage by hostile actors, with more than 50 Russian ships observed in areas of high cable density in the Baltic Sea. The UK is monitoring the Russian spy ship Yantar amid concerns that it is mapping critical underwater infrastructure. Concerns have also been raised about Chinese sabotage following a number of incidents around Taiwan.

Massive Expansion of Italy's Piracy Shield Underway (techdirt.com) 21

An anonymous reader quotes a report from Techdirt: Walled Culture has been following closely Italy's poorly designed Piracy Shield system. Back in December we reported how copyright companies used their access to the Piracy Shield system to order Italian Internet service providers (ISPs) to block access to all of Google Drive for the entire country, and how malicious actors could similarly use that unchecked power to shut down critical national infrastructure. Since then, the Computer & Communications Industry Association (CCIA), an international, not-for-profit association representing computer, communications, and Internet industry firms, has added its voice to the chorus of disapproval. In a letter (PDF) to the European Commission, it warned about the dangers of the Piracy Shield system to the EU economy [...]. It also raised an important new issue: the fact that Italy brought in this extreme legislation without notifying the European Commission under the so-called "TRIS" procedure, which allows others to comment on possible problems [...].

As well as Italy's failure to notify the Commission about its new legislation in advance, the CCIA believes that: this anti-piracy mechanism is in breach of several other EU laws. That includes the Open Internet Regulation which prohibits ISPs to block or slow internet traffic unless required by a legal order. The block subsequent to the Piracy Shield also contradicts the Digital Services Act (DSA) in several aspects, notably Article 9 requiring certain elements to be included in the orders to act against illegal content. More broadly, the Piracy Shield is not aligned with the Charter of Fundamental Rights nor the Treaty on the Functioning of the EU -- as it hinders freedom of expression, freedom to provide internet services, the principle of proportionality, and the right to an effective remedy and a fair trial.

Far from taking these criticisms to heart, or acknowledging that Piracy Shield has failed to convert people to paying subscribers, the Italian government has decided to double down, and to make Piracy Shield even worse. Massimiliano Capitanio, Commissioner at AGCOM, the Italian Authority for Communications Guarantees, explained on LinkedIn how Piracy Shield was being extended in far-reaching ways (translation by Google Translate, original in Italian). [...] That is, Piracy Shield will apply to live content far beyond sports events, its original justification, and to streaming services. Even DNS and VPN providers will be required to block sites, a serious technical interference in the way the Internet operates, and a threat to people's privacy. Search engines, too, will be forced to de-index material. The only minor concession to ISPs is to unblock domain names and IP addresses that are no longer allegedly being used to disseminate unauthorized material. There are, of course, no concessions to ordinary Internet users affected by Piracy Shield blunders.
In the future, Italy's Piracy Shield will add:
- 30-minute blackout orders not only for pirate sports events, but also for other live content;
- the extension of blackout orders to VPNs and public DNS providers;
- the obligation for search engines to de-index pirate sites;
- the procedures for unblocking domain names and IP addresses obscured by Piracy Shield that are no longer used to spread pirate content;
- the new procedure to combat piracy on the #linear and "on demand" television, for example to protect the #film and #serietv.

ESA's New Documentary Paints Worrying Picture of Earth's Orbital Junk Problem (inkl.com) 31

The European Space Agency's short film Space Debris: Is it a Crisis? highlights the growing danger of orbital clutter, warning that "70% of the 20,000 satellites ever launched remain in space today, orbiting alongside hundreds of millions of fragments left behind by collisions, explosions and intentional destruction." Inkl reports: The approximately eight-minute-long film "Space Debris: Is it a Crisis?" attempts to answer its conjecture with supportive statistics and orbital projections. [...] The film also mentions that the kind of Earth orbit matters when discussing whether we're in a space junk "crisis" -- though unfortunately, orbits at risk appear to be those with satellites that help with communication and navigation, as well as our fight against another primarily human-driven crisis: global warming. Still, the film emphasizes that solutions ought to be thought of carefully: "True sustainability is complex, and rushed solutions risk creating the problem of burden-shifting." You can watch the film on ESA's website.

Amazon Set To Launch First Operational Satellites For Project Kuiper Network (geekwire.com) 37

Amazon and United Launch Alliance will launch 27 full-scale satellites on April 9 as part of Amazon's Project Kuiper, marking the company's first major step toward building a global satellite internet network to rival SpaceX's Starlink. GeekWire reports: ULA said the three-hour window for the Atlas V rocket's liftoff from Cape Canaveral Space Force Station's Space Launch Complex 41 in Florida is scheduled to open at noon ET (9 a.m. PT) that day. ULA is planning a live stream of launch coverage via its website starting about 20 minutes ahead of liftoff. Amazon said next week's mission -- known as Kuiper-1 or KA-1 (for Kuiper Atlas 1) -- will put 27 Kuiper satellites into orbit at an altitude of 280 miles (450 kilometers).

ULA launched two prototype Kuiper satellites into orbit for testing in October 2023, but KA-1 will mark Amazon's first full-scale launch of a batch of operational satellites designed to bring high-speed internet access to millions of people around the world. [...] According to Amazon, the Kuiper satellite design has gone through significant upgrades since the prototypes were launched in 2023. Amazon's primary manufacturing facility is in Kirkland, Wash., with some of the components produced at Project Kuiper's headquarters in nearby Redmond.

The mission profile for KA-1 calls for deploying the satellites safely in orbit and establishing ground-to-space contact. The satellites would then use their electric propulsion systems to settle into their assigned orbits at an altitude of 392 miles (630 kilometers), under the management of Project Kuiper's mission operations team in Redmond. Under the current terms of its license from the Federal Communications Commission, Amazon is due to launch 3,232 Kuiper satellites by 2029, with half of those satellites going into orbit by mid-2026.

Micron Hikes Memory Prices Amid Surging AI Demand (tomshardware.com) 15

Micron will raise prices for DRAM and NAND flash memory chips through 2026 as AI and data center demand strains supply chains, the U.S. chipmaker confirmed Monday. The move follows a market rebound from previous oversupply, with memory prices steadily climbing as producers cut output while AI and high-performance computing workloads grow.

Rivals Samsung Electronics and SK Hynix are expected to implement similar increases. Micron cited "un-forecasted demand across various business segments" in communications to channel partners. The price hikes will impact sectors ranging from consumer electronics to enterprise data centers.

'An Open Letter To Meta: Support True Messaging Interoperability With XMPP' (xmpp.org) 31

In 1999 Slashdot reader Jeremie announced "a new project I recently started to create a complete open-source platform for Instant Messaging with transparent communication to other IM systems (ICQ, AIM, etc)." It was the first release of the eXtensible Messaging and Presence Protocol, and by 2008 Slashdot was asking if XMPP was "the next big thing." Facebook even supported it for third-party chat clients until 2015.

And here in 2025, the chair of the nonprofit XMPP Standards Foundation is long-time Slashdot reader ralphm, who is now issuing this call to action at XMPP.org: The European Digital Markets Act (DMA) is designed to break down walled gardens and enforce messaging interoperability. As a designated gatekeeper, Meta—controlling WhatsApp and Messenger—must comply. However, its current proposal falls short, risking further entrenchment of its dominance rather than fostering genuine competition. [..]

A Call to Action

The XMPP Standards Foundation urges Meta to adopt XMPP for messaging interoperability. It is ready to collaborate, continue to evolve the protocol to meet modern needs, and ensure true compliance with the DMA. Let's build an open, competitive messaging ecosystem—one that benefits both users and service providers.

It's time for real interoperability. Let's make it happen.

Madison Square Garden Bans Fan After Surveillance System IDs Him as Critic of Its CEO (theverge.com) 99

An anonymous reader quotes a report from The Verge: A concert on Monday night at New York's Radio City Music Hall was a special occasion for Frank Miller: his parents' wedding anniversary. He didn't end up seeing the show -- and before he could even get past security, he was informed that he was in fact banned for life from the venue and all other properties owned by Madison Square Garden (MSG). After scanning his ticket and promptly being pulled aside by security, Miller was told by staff that he was barred from the MSG properties for an incident at the Garden in 2021. But Miller says he hasn't been to the venue in nearly two decades.

"They hand me a piece of paper letting me know that I've been added to a ban list," Miller says. "There's a trespass notice if I ever show up on any MSG property ever again," which includes venues like Radio City, the Beacon Theatre, the Sphere, and the Chicago Theatre. He was baffled at first. Then it dawned on him: this was probably about a T-shirt he designed years ago. MSG Entertainment won't say what happened with Miller or how he was picked out of the crowd, but he suspects he was identified via controversial facial recognition systems that the company deploys at its venues.

In 2017, 1990s New York Knicks star Charles Oakley was forcibly removed from his seat near Knicks owner and Madison Square Garden CEO James Dolan. The high-profile incident later spiraled into an ongoing legal battle. For Miller, Oakley was an "integral" part of the '90s Knicks, he says. With his background in graphic design, he made a shirt in the style of the old team logo that read, "Ban Dolan" -- a reference to the infamous scuffle. A few years later, in 2021, a friend of Miller's wore a Ban Dolan shirt to a Knicks game and was kicked out and banned from future events. That incident spawned ESPN segments and news articles and validated what many fans saw as a pettiness on Dolan and MSG's part for going after individual fans who criticized team ownership.
"Frank Miller Jr. made threats against an MSG executive on social media and produced and sold merchandise that was offensive in nature," Mikyl Cordova, executive vice president of communications and marketing for the company, said in an emailed statement. "His behavior was disrespectful and disruptive and in violation of our code of conduct."

Miller responded to the ban, saying: "I just found it comical, until I was told that my mom was crying [in the lobby]. I was like, 'Oh man, I ruined their anniversary with my shit talk on the internet. Memes are powerful, and so is the surveillance state. It's something that we all have to be aware of -- the panopticon. We're [being] surveilled at all times, and it's always framed as a safety thing, when rarely is that the case. It's more of a deterrent and a fear tactic to try to keep people in line."

Signal President Blasts WhatsApp's Privacy Claims (cybernews.com) 59

Signal president Meredith Whittaker challenged recent assertions by WhatsApp head Will Cathcart that minimal differences exist between the two messaging platforms' privacy protections. "We're amused to see WhatsApp stretching the limits of reality to claim that they are just like Signal," Whittaker said in a statement published Monday, responding to Cathcart's comments to Dutch journalists last week.

While WhatsApp licenses Signal's end-to-end encryption technology, Whittaker said that WhatsApp still collects substantial user metadata, including "location data, contact lists, when they send someone a message, when they stop, what users are in their group chats, their profile picture, and much more." Cathcart had previously stated that WhatsApp doesn't track users' communications or share contact information with other companies, claiming "we strongly believe in private communication."

Is WhatsApp Being Ditched for Signal in Dutch Higher Education? (dub.uu.nl) 42

For weeks Signal has been one of the three most-downloaded apps in the Netherlands, according to a local news site. And now "Higher education institutions in the Netherlands have been looking for an alternative," according to DUB (an independent news site for the Utrecht University community): Employees of the Utrecht University of Applied Sciences (HU) were recently advised to switch to Signal. Avans University of Applied Sciences has also been discussing a switch...The National Student Union is concerned about privacy. The subject was raised at last week's general meeting, as reported by chair Abdelkader Karbache, who said: "Our local unions want to switch to Signal or other open-source software."
Besides being open source, Signal is a non-commercial nonprofit, the article points out — though its proponents suggest there's another big difference. "HU argues that Signal keeps users' data private, unlike WhatsApp." Cybernews.com explains the concern: In an interview with the Dutch newspaper De Telegraaf, Meredith Whittaker [president of the Signal Foundation] discussed the pitfalls of WhatsApp. "WhatsApp collects metadata: who you send messages to, when, and how often. That's incredibly sensitive information," she says.... The only information [Signal] collects is the date an account was registered, the time when an account was last active, and hashed phone numbers... Information like profile name and the people a user communicates with is all encrypted... Metadata might sound harmless, but it couldn't be further from the truth. According to Whittaker, metadata is deadly. "As a former CIA director once said: 'We kill people based on metadata'."
WhatsApp's metadata also includes IP addresses, TechRadar noted last May: Other identifiable data such as your network details, the browser you use, ISP, and other identifiers linked to other Meta products (like Instagram and Facebook) associated with the same device or account are also collected... [Y]our IP can be used to track down your location. As the company explained, even if you keep the location-related features off, IP addresses and other collected information like phone number area codes can be used to estimate your "general location."

WhatsApp is required by law to share this information with authorities during an investigation...

[U]nder scrutiny is how Meta itself uses these precious details for commercial purposes. Again, this is clearly stated in WhatsApp's privacy policy and terms of use. "We may use the information we receive from [other Meta companies], and they may use the information we share with them, to help operate, provide, improve, understand, customize, support, and market our Services and their offerings," reads the policy. This means that yes, your messages are always private, but WhatsApp is actively collecting your metadata to build your digital persona across other Meta platforms...

The article suggests using a VPN with WhatsApp and turning on its "advanced privacy feature" (which hides your IP address during calls) and managing the app's permissions for data collection. "While these steps can help reduce the amount of metadata collected, it's crucial to bear in mind that it's impossible to completely avoid metadata collection on the Meta-owned app... For extra privacy and security, I suggest switching to the more secure messaging app Signal."

The article also includes a cautionary anecdote. "It was exactly a piece of metadata — a Proton Mail recovery email — that led to the arrest of a Catalan activist."

Top Broadband Official Exits Commerce Department With Warning About Starlink (politico.com) 183

An anonymous reader quotes a report from Politico: A top Commerce Department official sent a blistering email to his former colleagues on his way out the door Sunday warning that the Trump administration is poised to unduly enrich Elon Musk's satellite internet company with money for rural broadband. The technology offered by Starlink ... is inferior, wrote Evan Feinman, who had directed the $42.5 billion broadband program for the past three years. "Stranding all or part of rural America with worse internet so that we can make the world's richest man even richer is yet another in a long line of betrayals by Washington," Feinman said.

Feinman's lengthy email, totaling more than 1,100 words and shared with POLITICO, is a sign of deep discomfort about the changes underway that will likely transform the Broadband Equity, Access and Deployment Program. Commerce Secretary Howard Lutnick recently pledged a vigorous review of BEAD, with an aim to rip out what he sees as extraneous requirements and remove any preference for particular broadband technologies like fiber. The program, created in the 2021 infrastructure law program, became a source of partisan fighting last year on the campaign trail as Republicans attacked the Biden administration for its slow pace. No internet expansion projects have begun using BEAD money, although some states were close at the beginning of this year. Feinman's critique: In his email, Feinman notes Friday was his last day leading BEAD and that he's "disappointed not to be able to see this project through."

Feinman's email warns the Trump administration could undermine BEAD and he encourages people to fight to retain its best aspects. Feinman said the administration should "NOT change it to benefit technology that delivers slower speeds at higher costs to the household paying the bill," adding that this isn't what rural America, congressional Republicans or Democrats, the states or the telecom industry wants. "Reach out to your congressional delegation and reach out to the Trump Administration and tell them to strip out the needless requirements, but not to strip away from states the flexibility to get the best connections for their people," Feinman wrote. He said he's not worried about the Trump administration nixing requirements around climate resiliency, labor and middle class affordability, saying those issues "were inserted by the prior administration for messaging/political purposes, and were never central to the mission of the program."
Feinman warns that changes to the BEAD program under the Trump administration could stall state-level broadband progress, with Louisiana, Delaware, and Nevada already stuck in review.

Meanwhile, no specific guidance or timeline for these changes has been provided, and Arielle Roth's confirmation as NTIA head is still pending in the Senate.

Alphabet Spins Off Laser-Based Internet Project Taara From 'Moonshot' Unit (ft.com) 22

Alphabet is spinning out Taara, a laser-based internet company from its X "moonshot" incubator, securing backing from Series X Capital while retaining a minority stake.

Taara's technology transmits data at 20 gigabits per second over 20km by firing pencil-width light beams between traffic light-sized terminals, extending traditional fiber-optic networks with minimal construction costs.

Based in Sunnyvale, California, the company operates in 12 countries, including India and parts of Africa, where it created a 5km laser link over the Congo River between Brazzaville and Kinshasa. The two-dozen-strong team partners with telecommunications firms like Bharti Airtel and T-Mobile to extend core fiber-optic networks to remote locations or dense urban areas.

Taara originated from Project Loon, which was shut down in 2021 after facing regulatory challenges. The company is developing silicon photonic chips to replace mirrors and lenses in its terminals and potentially enable multiple connections from a single transmitter.

After Meta Blocks Whistleblower's Book Promotion, It Becomes an Amazon Bestseller (thetimes.com) 39

After Meta convinced an arbitrator to temporarily prevent a whistleblower from promoting their book about the company (titled: Careless People), the book climbed to the top of Amazon's best-seller list. And the book's publisher Macmillan released a defiant statement that "The arbitration order has no impact on Macmillan... We will absolutely continue to support and promote it." (They added that they were "appalled by Meta's tactics to silence our author through the use of a non-disparagement clause in a severance agreement.")

Saturday the controversy was even covered by Rolling Stone: [Whistleblower Sarah] Wynn-Williams is a diplomat, policy expert, and international lawyer, with previous roles including serving as the Chief Negotiator for the United Nations on biosafety liability, according to her bio on the World Economic Forum...

Since the book's announcement, Meta has forcefully responded to the book's allegations in a statement... "Eight years ago, Sarah Wynn-Williams was fired for poor performance and toxic behavior, and an investigation at the time determined she made misleading and unfounded allegations of harassment. Since then, she has been paid by anti-Facebook activists and this is simply a continuation of that work. Whistleblower status protects communications to the government, not disgruntled activists trying to sell books."

But the negative coverage continues, with the Observer Sunday highlighting it as their Book of the Week. "This account of working life at Mark Zuckerberg's tech giant organisation describes a 'diabolical cult' able to swing elections and profit at the expense of the world's vulnerable..."

Though ironically Wynn-Williams started their career with optimism about Facebook's role in the app internet.org. . "Upon witnessing how the nascent Facebook kept Kiwis connected in the aftermath of the 2011 Christchurch earthquake, she believed that Mark Zuckerberg's company could make a difference — but in a good way — to social bonds, and that she could be part of that utopian project...

What internet.org involves for countries that adopt it is a Facebook-controlled monopoly of access to the internet, whereby to get online at all you have to log in to a Facebook account. When the scales fall from Wynn-Williams's eyes she realises there is nothing morally worthwhile in Zuckerberg's initiative, nothing empowering to the most deprived of global citizens, but rather his tool involves "delivering a crap version of the internet to two-thirds of the world". But Facebook's impact in the developing world proves worse than crap. In Myanmar, as Wynn-Williams recounts at the end of the book, Facebook facilitated the military junta to post hate speech, thereby fomenting sexual violence and attempted genocide of the country's Muslim minority. "Myanmar," she writes with a lapsed believer's rue, "would have been a better place if Facebook had not arrived." And what is true of Myanmar, you can't help but reflect, applies globally...

"Myanmar is where Wynn-Williams thinks the 'carelessness' of Facebook is most egregious," writes the Sunday Times: In 2018, UN human rights experts said Facebook had helped spread hate speech against Rohingya Muslims, about 25,000 of whom were slaughtered by the Burmese military and nationalists. Facebook is so ubiquitous in Myanmar, Wynn-Williams points out, that people think it is the entire internet. "It's no surprise that the worst outcome happened in the place that had the most extreme take-up of Facebook." Meta admits it was "too slow to act" on abuse in its Myanmar services....

After Wynn-Williams left Facebook, she worked on an international AI initiative, and says she wants the world to learn from the mistakes we made with social media, so that we fare better in the next technological revolution. "AI is being integrated into weapons," she explains. "We can't just blindly wander into this next era. You think social media has turned out with some issues? This is on another level."

NAB Calls For End of ATSC 1.0 (broadbandtvnews.com) 47

An anonymous reader quotes a report from Broadband TV News: The National Association of Broadcasters (NAB) has filed a petition with the Federal Communications Commission (FCC) urging the agency to establish a clear, industry-wide transition plan for the full deployment of Next Gen TV (ATSC 3.0). The proposal outlines a two-phased transition while modernizing regulatory requirements to support consumer access and innovation. [...] Under the plan, stations in the top 55 markets, covering 70% of the US population, would transition by February 2028, with all remaining full-power and Class A stations following in or before February 2030. The petition also calls for updates to FCC rules to ensure television reception devices support Next Gen TV, maintain existing MVPD carriage obligations and eliminate regulatory hurdles that could slow adoption. To clarify, ATSC 1.0 is the current standard for free over-the-air (OTA) TV. While ATSC 3.0 (also called NextGen TV) is its intended replacement, it's not backward-compatible, meaning consumers need new equipment to receive it. NAB's petition is to allow a complete shutdown of ATSC 1.0 to accelerate the transition to ATSC 3.0, meaning older TV setups relying on free OTA signals would stop working unless consumers upgrade their equipment. Their argument is that ATSC 3.0 adoption has been slow, and networks would benefit more from shifting away from OTA broadcasting entirely.

Reddit user bshensky argues that shutting down OTA TV would benefit large media corporations and harm independent stations. It's also worth noting that OTA TV operates on valuable spectrum, which could be repurposed for mobile broadband (this has happened before), benefiting cellular providers.

Leaked Apple Meeting Shows How Dire the Siri Situation Really Is (theverge.com) 51

A leaked Apple meeting reveals significant internal struggles with Siri's development, as AI-powered features announced last June have been delayed and may not make it into iOS 19. The Verge reports: Bloomberg (paywalled) has the full scoop on what happened at a Siri team meeting led by senior director Robby Walker, who oversees the division. He called the delay an "ugly" situation and sympathized with employees who might be feeling burned out or frustrated by Apple's decisions and Siri's still-lackluster reputation. He also said it's not a given that the missing Siri features will make it into iOS 19 this year; that's the company's current target, but "doesn't mean that we're shipping then," he told employees. "We have other commitments across Apple to other projects," Walker said, according to Bloomberg's report. "We want to keep our commitments to those, and we understand those are now potentially more timeline-urgent than the features that have been deferred."

The meeting also hinted at tension between Apple's Siri unit and the marketing division. Walker said the communications team wanted to highlight features like Siri understanding personal context and being able to take action based on what's currently on a user's screen -- even though they were nowhere near ready. Those WWDC teases and the resulting customer expectations only made matters worse, Walker acknowledged. Apple has since pulled an iPhone 16 ad that showcased the features and has added disclaimers to several areas of its website noting they've all been punted to a TBD date. They were held back in part due to quality issues "that resulted in them not working properly up to a third of the time," according to Mark Gurman.

[...] Walker told his staff that senior executives like software chief Craig Federighi and AI boss John Giannandrea are taking "intense personal accountability" for a predicament that's drawing fierce criticism as the months pass by with little to show for it beyond a prettier Siri animation. "Customers are not expecting only these new features but they also want a more fully rounded-out Siri," Walker said. "We're going to ship these features and more as soon as they are ready." He praised the team for its "incredibly impressive" work so far. "These are not quite ready to go to the general public, even though our competitors might have launched them in this state or worse," he said of the delayed features.

T-Mobile Raising Rates for More Legacy Customers (cnet.com) 45

After raising rates last June for customers on some of its older plans, T-Mobile is pushing up costs again -- but it's not entirely clear how many people are affected. From a report: According to a memo obtained by CNET and sent to T-Mobile employees early this morning, some people will see a $5 per-line increase beginning with their April or May bills.

The memo by Jon Freier, president of T-Mobile's consumer group, states that customers affected by the price hike should be notified by the end of today, March 13. Only those who receive a notice will see the rate increase.

Freier cites the "rising costs over the past several years" as the impetus behind the price push. Other carriers are facing the same headwinds, such as Verizon last December and this January, and AT&T last January and June.

Supercomputer Draws Molecular Blueprint For Repairing Damaged DNA (phys.org) 10

Using the Summit supercomputer at the Department of Energy's Oak Ridge National Laboratory, researchers have modeled a key component of nucleotide excision repair (NER) called the pre-incision complex (PInC), which plays a crucial role in DNA damage repair. Their study, published in Nature Communications, provides new insights into how the PInC machinery orchestrates precise DNA excision, potentially leading to advancements in treating genetic disorders, preventing premature aging, and understanding conditions like xeroderma pigmentosum and Cockayne syndrome. Phys.Org reports: "Computationally, once you assemble the PInC, molecular dynamics simulations of the complex become relatively straightforward, especially on large supercomputers like Summit," [said lead investigator Ivaylo Ivanov, a chemistry professor at Georgia State University]. Nanoscale Molecular Dynamics, or NAMD, is a molecular dynamics code specifically designed for supercomputers and is used to simulate the movements and interactions of large biomolecular systems that contain millions of atoms. Using NAMD, the research team ran extensive simulations. The number-crunching power of the 200-petaflop Summit supercomputer -- capable of performing 200,000 trillion calculations per second -- was essential in unraveling the functional dynamics of the PInC complex on a timescale of microseconds. "The simulations showed us a lot about the complex nature of the PInC machinery. It showed us how these different components move together as modules and the subdivision of this complex into dynamic communities, which form the moving parts of this machine," Ivanov said.

The findings are significant in that mutations in XPF and XPG can lead to severe human genetic disorders. They include xeroderma pigmentosum, which is a condition that makes people more susceptible to skin cancer, and Cockayne syndrome, which can affect human growth and development, lead to impaired hearing and vision, and speed up the aging process. "Simulations allow us to zero in on these important regions because mutations that interfere with the function of the NER complex often occur at community interfaces, which are the most dynamic regions of the machine," Ivanov said. "Now we have a much better understanding of how and from where these disorders manifest."

SpaceX Readies Starlink India Launch 32

SpaceX's Starlink has secured its first agreement in India, partnering with telecommunications leader Bharti Airtel to bring high-speed satellite internet to the world's most populous country, the companies announced Tuesday [PDF].

The landmark deal will enable Starlink to tap into Airtel's extensive retail network and ground infrastructure while expanding its global reach into previously underserved regions across India, pending regulatory authorizations.

"We are excited to work with Airtel and unlock the transformative impact Starlink can bring to the people of India," said Gwynne Shotwell, President and Chief Operating Officer of SpaceX. "The team at Airtel has played a pivotal role in India's telecom story, so working with them to complement our direct offering makes great sense for our business."

The collaboration will explore selling Starlink equipment through Airtel's retail stores and offering services to business customers while connecting communities in rural areas with limited connectivity.

Axiom Space and Red Hat Will Bring Edge Computing to the International Space Station (theregister.com) 7

Axiom Space and Red Hat will collaborate to launch Data Center Unit-1 (AxDCU-1) to the International Space Station this spring. It's a small data processing prototype (powered by lightweight, edge-optimized Red Hat Device Edge) that will demonstrate initial Orbital Data Center (ODC) capabilities.

"It all sounds rather grand for something that resembles a glorified shoebox," reports the Register. Axiom Space said: "The prototype will test applications in cloud computing, artificial intelligence, and machine learning (AI/ML), data fusion and space cybersecurity."

Space is an ideal environment for edge devices. Connectivity to datacenters on Earth is severely constrained, so the more processing that can be done before data is transmitted to a terrestrial receiving station, the better. Tony James, chief architect, Science and Space at Red Hat, said: "Off-planet data processing is the next frontier, and edge computing is a crucial component. With Red Hat Device Edge and in collaboration with Axiom Space, Earth-based mission partners will have the capabilities necessary to make real-time decisions in space with greater reliability and consistency...."

The Red Hat Device Edge software used by Axiom's device combines Red Hat Enterprise Linux, the Red Hat Ansible Platform, and MicroShift, a lightweight Kubernetes container orchestration service derived from Red Hat OpenShift. The plan is for Axiom Space to host hybrid cloud applications and cloud-native workloads on-orbit. Jason Aspiotis, global director of in-space data and security, Axiom Space, told The Register that the hardware itself is a commercial off-the-shelf unit designed for operation in harsh environments... "AxDCU-1 will have the ability to be controlled and utilized either via ground-to-space or space-to-space communications links. Our current plans are to maintain this device on the ISS. We plan to utilize this asset for at least two years."

The article notes that HPE has also "sent up a succession of Spaceborne computers — commercial, off-the-shelf supercomputers — over the years to test storage, recovery, and operational potential on long-duration missions." (They apparently use Red Hat Enterprise Linux.) "At the other end of the scale, the European Space Agency has run Raspberry Pi computers on the ISS for years as part of the AstroPi educational outreach program."

Axiom Space says their Orbital Data Center is deigned to "reduce delays traditionally associated with orbital data processing and analysis." By utilizing Earth-independent cloud storage and edge processing infrastructure, Axiom Space ODCs will enable data to be processed closer to its source, spacecraft or satellites, bypassing the need for terrestrial-based data centers. This architecture alleviates reliance on costly, slow, intermittent or contested network connections, creating more secure and quicker decision-making in space.

The goal is to allow Axiom Space and its partners to have access to real-time processing capabilities, laying the foundation for increased reliability and improved space cybersecurity with extensive applications.

Rayhunter: A Cheap New Tool from EFF to Detect Cellular Spying (androidauthority.com) 23

Equuleus42 (Slashdot reader #723) brings word that the Electronic Frontier Foundation (EFF) is sharing a new tool for fighting back against cellphone surveillance by Stingray cell-site simulators.

Android Authority reports: "Rayhunter" uses an open-source software package designed to look for evidence of IMSI catchers in action, running on an old Orbic Speed RC400L mobile hotspot. The great thing about that choice is that you can pick one up for practically nothing — we're seeing them listed for barely over $10 on Amazon, and you can find them even cheaper on eBay. There's an installation script for Macs and Linux to automate getting set up, but once the Orbic is flashed with the Rayhunter software, it should be ready go, collecting data about sketchy-looking "cell towers" it picks up.

Right now, much of the use of IMSI catchers is still shrouded in mystery, with the groups who regularly employ them extremely hesitant to disclose their methods. As a result, a big focus of this EFF project is just getting more info on how and where these are actually used, giving protestors a better sense of the steps they'll need to take if they want to protect their privacy.

Why Most Countries Are Struggling To Shut Down 2G (restofworld.org) 56

Global telecom operators are struggling to shut down aging 2G networks despite pressure to free up spectrum for 4G and 5G services, as the transition threatens to exclude millions of vulnerable users.

While Vietnam successfully decommissioned 2G in November 2024 by providing free 4G phones to low-income users, countries like South Africa and India have delayed shutdowns over concerns about cutting off phone access for millions. According to GSMA Intelligence, 61 countries have planned or initiated 2G network shutdowns to enhance bandwidth and reduce maintenance costs. For 2.5 billion people worldwide, smartphones cost about 30% of monthly income, keeping basic phones essential despite declining global feature phone sales.
