American airlines have transformed into financial services companies that happen to fly planes as loyalty programs now constitute their primary profit engine rather than passenger transport. Delta, American, Southwest, and United all operated their passenger services at a loss in 2024 while generating $14 billion in combined operating profits from credit card partnerships. Delta received $2.1 billion from American Express in Q2 2025 -- exactly matching its total operating profit -- while the airline's passenger operations alone would have posted a loss. These loyalty programs command valuations in the tens of billions, sometimes exceeding the airlines' total equity value, with Delta reporting 1% of U.S. GDP flows through its co-branded cards. Customers can now reach American Airlines' top loyalty tier without boarding a single flight.

Intel's chief executive Lip-Bu Tan has hit out at "misinformation" over his career after U.S. President Donald Trump alleged the semiconductor industry veteran was "highly conflicted" and should resign. From a report: In a letter to Intel staff published late on Thursday, Tan said that Intel was "engaging" with the Trump administration "to address the matters that have been raised and ensure they have the facts." "There has been a lot of misinformation circulating about my past roles...âI want to be absolutely clear: Over 40+ years in the industry, I've built relationships around the world and across our diverse ecosystem -- and I have always operated within the highest legal and ethical standards," Tan wrote. Tan's move to reassure staff at Intel, the only US-headquartered company capable of manufacturing advanced chips, came hours after Trump had demanded his resignation in a post on Truth Social. Trump did not detail Tan's alleged conflicts of interest but the U.S. president's broadside followed a letter from Tom Cotton, the Republican head of the Senate intelligence committee, to Intel's chair expressing "concern about the security and integrity of Intel's operations" and Tan's ties to China.

alternative_right quotes a report from The Register: Space fans looking to camp out in style have a chance to pick up an Airstream trailer that once served as the Convoy Command Vehicle for NASA's Space Shuttle operations at Edwards Air Force Base -- if they have a couple hundred thousand to spare, that is. "This is the NASA 025 Command Vehicle," current owner Jonathan Kitzen says of the once-silver, now paint-daubed and otherwise unassuming Airstream trailer. "NASA 025 was designed to land crewed missions at Edwards Air Force Base. [Airstream] informed me that this was, in their, words, 'the only NASA Airstream ever sold,' and the others [001-024] were all crushed or in museums. The sister crew vehicle (a 28-ft with one rear axle) is sitting at Kennedy museum [the Kennedy Space Center Visitor Complex]. All the rest are gone, except for this one." Kitzen picked up the vehicle in 2022 up after spotting it on a government surplus auction site, where it had been listed with few details and at a very low starting price. As for how the rare vehicle ended up for sale in the first place, Kitzen says he was told it was a mistake. "Apparently there was some miscommunication when the vehicle was decommissioned," he claims in the sale listing. "It should have been offered to museums but the sales team did not know what it was. They were told it was just a 'NASA vehicle,' they did not know it had any special status or history. To the sellers they thought it was just a van that could have been for moving laundry around the base. It was an accidental (yet valid) sale. "When I pulled up to Vandenberg Air Force Base after getting my NASA contractor badge I was greeted by the senior asset manager," Kitzen continues. "'We didn't know what we were selling!' were the first words out of her mouth. 'We didn't advertise it or offer it up to museums, the phone has exploded. Nobody told us what it was!'" [...] The listing on vehicle sale site Hemmings.com has an asking price of $199,000, though with no offers yet submitted. A listing on eBay with a $50,000 minimum bid and $290,000 buy-it-now price ended in May with no takers.

alternative_right shares an interview from The Register with David W. Hill, who served as lead designer for ThinkPad from 1995 to 2017. Here are some excerpts from the wide-ranging interview: Hill revealed that he tried several times to introduce additional laptops that had the famous "butterfly keyboard" found on the ThinkPad 701C. [...] Hill told The Register that he had wanted to make more ThinkPads with butterfly keyboards and had tried at least three times to make it happen -- in one case there was a prototype where only half of the keyboard moved -- but was never able to get there. Eventually, screens became big enough that there was no need to have a keyboard that expanded. However, Hill said, he thought about putting a butterfly keyboard on a netbook when they were a viable product category in the late aughts. [...] One of the features Hill is most proud of developing is the ThinkLight, an overhead light located above the screen that lit up the entire keyboard and deck. Though the advent of keyboard backlights has made the ThinkLight redundant -- Lenovo discontinued it in 2013 -- it offers capabilities that backlights do not. If you want to place a paper on top of your keyboard, the LED will light it up, allowing you to see more than just your key legends. ... When designing the 25th anniversary ThinkPad, which came out in 2017, Hill brought back the ThinkLight, but he actually wanted to have -- for the first time -- two LEDs instead of one. The dual lights would have eliminated shadows and provided even better illumination, but unfortunately, this effort proved too costly to make it into the final product. [...] When I asked Hill about products he wanted to come out with but never got to, he talked about an idea for portable workstations that would fold up like a laptop but have a separate keyboard and screen like a desktop when you put them on your desk. He collaborated with butterfly keyboard creator John Karidis on this concept, but couldn't make it ready for market. "We did a lot of experimentation with laptops that sort of unfolded to be more like a desktop: things where the display elevated or the keyboard would remove so you could use them like a workstation, rather than just being a clamshell with a hinge, you open and close," Hill recalled. "We did a lot of experimentation with that and got close a few times, but never could completely sell it. I always thought it was an opportunity to create a new category."

Ancient Slashdot reader Epeeist shares a report from The Guardian: The newest version of the maglev train is capable of traveling at 600km/h (about 370mph). However, the train's engineers have wrestled with the problem of the shock waves which occur as the train exits the mouth of a tunnel. When a high-speed train enters an enclosed space such as a tunnel, air in front is compressed, like in a piston. The resulting fluctuations in air pressure coalesce at the tunnel mouth, generating low-frequency shock waves. These are colloquially known as a "tunnel boom" -- a related, albeit different phenomenon to the "sonic boom" heard as aircraft pass the speed of sound. Tunnel booms pose serious challenges to operational safety, as the shock waves can disturb humans and animals nearby, as well as causing structural damage. Now, however, researchers have discovered that placing innovative soundproofing buffers at tunnel mouths can reduce shock waves by up to 96%. This promises improvements in operational safety, noise pollution and passenger comfort, as well as safeguarding animals in the vicinity of future lines. [...] The porous structure of the new 100-meter long buffers, combined with porous coatings on the tunnel body, allow the trapped air to escape before the train reaches the tunnel mouth, suppressing the boom in the same way as a silencer fitted to a firearm.

Duolingo's decision to go "AI-first" sparked backlash from users, but the company's second quarter earnings result tell a different story. Quarterly revenue exceeded expectations, stock surged nearly 30%, and daily active users grew 40% year-over-year. TechCrunch reports: Now the company anticipates making over $1 billion in revenue this year, and daily active users have grown 40% year-over-year. The growth is significant but falls in the lower range of the company's estimates of growing between 40% and 45%, which an investor brought up to [CEO Luis von Ahn] on Wednesday's quarterly earnings call. "The reason we came [in] towards the lower end was because I said some stuff about AI, and I didn't give enough context. Because of that, we got some backlash on social media," von Ahn said. "The most important thing is we wanted to make the sentiment on our social media positive. We stopped posting edgy posts and started posting things that would get our sentiment more positive. That has worked."

An anonymous reader quotes a report from Wired: Two years ago, researchers in the Netherlands discovered an intentional backdoor in an encryption algorithm baked into radios used by critical infrastructure -- as well as police, intelligence agencies, and military forces around the world -- that made any communication secured with the algorithm vulnerable to eavesdropping. When the researchers publicly disclosed the issue in 2023, the European Telecommunications Standards Institute (ETSI), which developed the algorithm, advised anyone using it for sensitive communication to deploy an end-to-end encryption solution on top of the flawed algorithm to bolster the security of their communications. But now the same researchers have found that at least one implementation of the end-to-end encryption solution endorsed by ETSI has a similar issue that makes it equally vulnerable to eavesdropping. The encryption algorithm used for the device they examined starts with a 128-bit key, but this gets compressed to 56 bits before it encrypts traffic, making it easier to crack. It's not clear who is using this implementation of the end-to-end encryption algorithm, nor if anyone using devices with the end-to-end encryption is aware of the security vulnerability in them. Wired notes that the end-to-end encryption the researchers examined is most commonly used by law enforcement and national security teams. "But ETSI's endorsement of the algorithm two years ago to mitigate flaws found in its lower-level encryption algorithm suggests it may be used more widely now than at the time."
