  • Blue Origin's Satellite Internet Network TeraWave Will Move Data At 6 Tbps
    by BeauHD on 22/01/2026 at 7:00 am

    Blue Origin has unveiled an enterprise-focused satellite internet network called TeraWave, which promises up to 6 Tbps speeds via a mixed low- and medium-Earth orbit constellation. TechCrunch reports: The TeraWave constellation will use a mix of 5,280 satellites in low-Earth orbit and 128 in medium-Earth orbit, and Blue Origin plans to deploy the first ones in late 2027. It's not immediately clear how long Blue Origin expects it will take to build out the whole network. The low-Earth orbit satellites Blue Origin is building will use RF connectivity and have a max data transfer speed of 144 Gbps, while the medium-Earth variety will use an optical link that can achieve the much higher 6 Tbps speed. For reference, SpaceX's Starlink currently maxes out at 400 Mbps -- though it plans to launch upgraded satellites that will offer 1 Gbps data transfer in the future. "We identified an unmet need with customers who were seeking enterprise-grade internet access with higher speeds, symmetrical upload/download speeds, more redundancy, and rapid scalability for their networks. TeraWave solves for these problems," Blue Origin said in a statement. Read more of this story at Slashdot.

  • Weight-Loss Drugs Could Save US Airlines $580 Million Per Year
    by BeauHD on 22/01/2026 at 3:30 am

    An anonymous reader quotes a report from the New York Times: Weight-loss drugs like Ozempic have transformed millions of lives with easily administered treatments and quick results. Now it turns out the dropped pounds may have a surprising perk for airlines, too: lower fuel costs, as slimmer passengers lighten their aircraft's loads. According to a study published last week by Jefferies, a financial services firm, the four largest U.S. carriers -- American Airlines, Delta Air Lines, Southwest Airlines and United Airlines -- could together save as much as $580 million per year on fuel thanks to weight-loss drugs, known as GLP-1s. One in eight U.S. adults said they were taking a GLP-1 in a November survey published by KFF, a nonprofit health research group. Fuel is among airlines' largest expenses. The Jefferies study estimates that the four airlines will together consume 16 billion gallons of fuel in 2026 at a total cost of $38.6 billion, nearly 20 percent of their total expenses. The savings from skinnier passengers would amount to just 1.5 percent of fuel costs. But airlines and pilots must scrutinize even the smallest changes to a plane's weight and balance, and a lighter payload means each jet burns less fuel to generate the thrust necessary to fly. Investors could also stand to benefit: The researchers estimated that a 2 percent reduction in aircraft weight could boost earnings per share by about 4 percent. "Please note savings are before any lost snack sales," the Jefferies analysts added. Read more of this story at Slashdot.

  • FBI's Washington Post Investigation Shows How Your Printer Can Snitch On You
    by BeauHD on 22/01/2026 at 2:02 am

    alternative_right quotes a report from The Intercept: Federal prosecutors on January 9 charged Aurelio Luis Perez-Lugones, an IT specialist for an unnamed government contractor, with "the offense of unlawful retention of national defense information," according to an FBI affidavit (PDF). The case attracted national attention after federal agents investigating Perez-Lugones searched the home of a Washington Post reporter. But overlooked so far in the media coverage is the fact that a surprising surveillance tool pointed investigators toward Perez-Lugones: an office printer with a photographic memory. News of the investigation broke when the Washington Post reported that investigators seized the work laptop, personal laptop, phone, and smartwatch of journalist Hannah Natanson, who has covered the Trump administration's impact on the federal government and recently wrote about developing more than 1,000 government sources. A Justice Department official told the Post that Perez-Lugones had been messaging Natanson to discuss classified information. The affidavit does not allege that Perez-Lugones disseminated national defense information, only that he unlawfully retained it. The affidavit provides insight into how Perez-Lugones allegedly attempted to exfiltrate information from a Secure Compartmented Information Facility, or SCIF, and the unexpected way his employer took notice. According to the FBI, Perez-Lugones printed a classified intelligence report, albeit in a roundabout fashion. It's standard for workplace printers to log certain information, such as the names of files they print and the users who printed them. In an apparent attempt to avoid detection, Perez-Lugones, according to the affidavit, took screenshots of classified materials, cropped the screenshots, and pasted them into a Microsoft Word document. By using screenshots instead of text, there would be no record of a classified report printed from the specific workstation. (Depending on the employer's chosen data loss prevention monitoring software, access logs might show a specific user had opened the file and perhaps even tracked whether they took screenshots). Perez-Lugones allegedly gave the file an innocuous name, "Microsoft Word - Document1," that might not stand out if printer logs were later audited. In this case, however, the affidavit reveals that Perez-Lugones's employer could see not only the typical metadata stored by printers, such as file names, file sizes, and time of printing, but it could also view the actual contents of the printed materials -- in this case, prosecutors say, the screenshots themselves. As the affidavit points out, "Perez-Lugones' employer can retrieve records of print activity on classified systems, including copies of printed documents." [...] Aside from attempting to surreptitiously print a document, Perez-Lugones, investigators say, was also seen allegedly opening a classified document and taking notes, looking "back and forth between the screen corresponding the classified system and the notepad, all the while writing on the notepad." The affidavit doesn't state how this observation was made, but it strongly suggests a video surveillance system was also in play. Read more of this story at Slashdot.

  • 'America Is Slow-Walking Into a Polymarket Disaster'
    by BeauHD on 22/01/2026 at 1:25 am

    In an opinion piece for The Atlantic, senior editor Saahil Desai argues that media outlets are increasingly treating prediction markets like Polymarket and Kalshi as legitimate signals of reality. The risk, as Desai warns, is a future where news coverage amplifies manipulable betting odds and turns politics, geopolitics, and even tragedy into speculative gambling theater. Here's an excerpt from the report: [...] The problem is that prediction markets are ushering in a world in which news becomes as much about gambling as about the event itself. This kind of thing has already happened to sports, where the language of "parlays" and "covering the spread" has infiltrated every inch of commentary. ESPN partners with DraftKings to bring its odds to SportsCenter and Monday Night Football; CBS Sports has a betting vertical; FanDuel runs its own streaming network. But the stakes of Greenland's future are more consequential than the NFL playoffs. The more that prediction markets are treated like news, especially heading into another election, the more every dip and swing in the odds may end up wildly misleading people about what might happen, or influencing what happens in the real world. Yet it's unclear whether these sites are meaningful predictors of anything. After the Golden Globes, Polymarket CEO Shayne Coplan excitedly posted that his site had correctly predicted 26 of 28 winners, which seems impressive -- but Hollywood awards shows are generally predictable. One recent study found that Polymarket's forecasts in the weeks before the 2024 election were not much better than chance. These markets are also manipulable. In 2012, one bettor on the now-defunct prediction market Intrade placed a series of huge wagers on Mitt Romney in the two weeks preceding the election, generating a betting line indicative of a tight race. The bettor did not seem motivated by financial gain, according to two researchers who examined the trades. "More plausibly, this trader could have been attempting to manipulate beliefs about the odds of victory in an attempt to boost fundraising, campaign morale, and turnout," they wrote. The trader lost at least $4 million but might have shaped media attention of the race for less than the price of a prime-time ad, they concluded. [...] The irony of prediction markets is that they are supposed to be a more trustworthy way of gleaning the future than internet clickbait and half-baked punditry, but they risk shredding whatever shared trust we still have left. The suspiciously well-timed bets that one Polymarket user placed right before the capture of Nicolas Maduro may have been just a stroke of phenomenal luck that netted a roughly $400,000 payout. Or maybe someone with inside information was looking for easy money. [...] As Tarek Mansour, Kalshi's CEO, has said, his long-term goal is to "financialize everything and create a tradable asset out of any difference in opinion." (Kalshi means "everything" in Arabic.) What could go wrong? As one viral post on X recently put it, "Got a buddy who is praying for world war 3 so he can win $390 on Polymarket." It's a joke. I think. Read more of this story at Slashdot.

  • Apple Reportedly Replacing Siri Interface With Actual Chatbot Experience For iOS 27
    by BeauHD on 22/01/2026 at 12:45 am

    According to Bloomberg's Mark Gurman, Apple is reportedly planning a major Siri overhaul in iOS 27 and macOS 27 where the current assistant interface will be replaced with a deeply integrated, ChatGPT-style chatbot experience. "Users will be able to summon the new service the same way they open Siri now, by speaking the 'Siri' command or holding down the side button on their iPhone or iPad," says Gurman. "More significantly, Siri will be integrated into all of the company's core apps, including ones for mail, music, podcasts, TV, Xcode programming software and photos. That will allow users to do much more with just their voice." 9to5Mac reports: The unannounced Siri overhaul will reportedly be revealed at WWDC in June as the flagship feature for iOS 27 and macOS 27. Its release is expected in September when Apple typically ships major software updates. While Apple plans to release an improved version of Siri and Apple Intelligence this spring, that version will use the existing Siri interface. The big difference is that Google's Gemini models will power the intelligence. With the bigger update planned for iOS 27, the iOS 26 upgrade to Siri and Apple Intelligence sounds more like the first step to a long overdue modernization. Gurman reports that the major Siri overhaul will "allow users to search the web for information, create content, generate images, summarize information and analyze uploaded files" while using "personal data to complete tasks, being able to more easily locate specific files, songs, calendar events and text messages." People are already familiar with conversational interactions with AI, and Bloomberg says the bigger update to Siri will be support both text and voice. Siri already uses these input methods, but there's no real continuity between sessions. Read more of this story at Slashdot.

  • Spotify Lawsuit Triggered Anna's Archive Domain Name Suspensions
    by BeauHD on 22/01/2026 at 12:02 am

    An anonymous reader quotes a report from TorrentFreak: Spotify and several major record labels, including UMG, Sony, and Warner, have taken legal action against the unknown operators of Anna's Archive. The action follows the shadow library's announcement that it would release hundreds of terabytes of scraped Spotify data. Unsealed documents reveal that the court already issued a broad preliminary injunction, ordering hosting companies, Cloudflare, and domain name services, to take action. [...] All these documents were filed under seal, as the shadow library might otherwise be tipped off and take countermeasures. These documents were filed ex-parte and kept away from Anna's Archive. According to Spotify and the labels, this is needed "so that Anna's Archive cannot pre-emptively frustrate" the countermeasures they seek. The lawsuit (PDF), which was unsealed recently, explains directly why Anna's Archive lost several of its domain names over the past weeks. The .ORG domain was suspended by the U.S.-based Public Interest Registry (PIR) in early January, while a domain registrar took the .SE variant offline a few days later. "We don't believe this has to do with our Spotify backup," AnnaArchivist said at the time, but court records prove them wrong. The unsealed paperwork shows that the court granted a temporary restraining order (TRO) on January 2, which aimed to target Anna's Archive hosting and domain names. The sealed nature of this order also explains why the .ORG registry informed us that it could not comment on the suspension last week. While the .ORG and the .SE domains are suspended now, other domains remain operational. This suggests that the responsible registrars and registries do not automatically comply with U.S. court orders. [...] While the unsealed documents resolve the domain suspension mystery, it is only the start of the legal battle in court. It is expected that Spotify and the music companies will do everything in their power to take further action, if needed. Interestingly, however, it appears that the music industry lawsuit may have already reached its goal. A few days ago, the dedicated Spotify download section was removed by Anna's Archive. Whether this removal is linked to the legal troubles is unknown. However, it appears that Anna's Archive stopped the specific distribution of Spotify content alleged in the complaint, seemingly in partial compliance with the injunction's ban on 'making available' the scraped files.
