American Airlines Picks Starlink For In-Flight Wi-Fi

American Airlines plans to install SpaceX's Starlink Wi-Fi on more than 500 narrow-body Airbus aircraft starting early next year. It does not, however, have any immediate plans to change providers on its Boeing fleet, which currently uses a mix of Viasat and Panasonic. CNBC reports: American in January rolled out free in-flight Wi-Fi for members of its frequent flyer program, following United Airlines, Delta Air Lines and others. Delta in March said it would use Amazon Leo for in-flight Wi-Fi for hundreds of jets starting in 2028. United, Southwest Airlines and Alaska Airlines, which merged with Hawaiian Airlines in 2024, have selected Starlink. The move is a big win for SpaceX as it prepares for a potentially massive IPO next month. SpaceX said Starlink and its connectivity business generated $11.39 billion in revenue last year, accounting for 61% of the company's total sales.

A Fundamental Principle of Aeronautical Engineering Has Been Overturned

An anonymous reader quotes a report from Wired: Aerodynamic drag is a major "barrier" in high-speed airplanes, automobiles, and bullet trains. This is because a design with less aerodynamic drag allows the aircraft to move at higher speeds with less energy. When an aircraft or car body moves at high speed, a thin layer of air called the "boundary layer" is formed on its surface. This boundary layer has two states: laminar flow, in which air flows in an orderly fashion, and turbulent flow, which involves turbulence. The longer the air stays in the laminar flow state with low friction, the smaller the air resistance becomes, but as the air speed increases, it transitions to turbulent flow. The key to reducing aerodynamic drag is how to delay this transition to turbulence. For more than 80 years, the principle of "the surface of an object must be smooth" has been the basic premise of aeronautical engineering throughout the world in order to suppress the transition to turbulence and reduce aerodynamic drag. This premise was based on the results of a 1940 study by Ichiro Tani, a Japanese aerodynamicist who quantitatively demonstrated the relationship between "surface roughness" (an indicator of the state of the machined surface) and turbulent transition, arguing that surface roughness, which was unavoidable with the manufacturing technology of the time, prevented laminar flow from being realized. However, in 1989 Tani reinterpreted the experimental data on rough-surface pipes obtained by fluid engineer Johann Nikulase in the 1930s, bringing a new perspective that "roughness may not necessarily only promote turbulent transition and increase fluid resistance." Inheriting this idea, a research group led by Yasuaki Kohama of Tohoku University experimentally demonstrated in the 1990s that fibrous rough surfaces, which have fine fibrous irregularities on their surface, have the effect of delaying transition under certain conditions. The same Tohoku University research team recently announced a discovery that significantly advances this trend. Aiko Yakino, associate professor at Tohoku University's Institute of Fluid Science, and her research group were the first in the world to demonstrate that aerodynamic drag can be reduced by up to 43.6 percent simply by applying distributed micro-roughness (DMR), a surface roughness so fine and irregular that it cannot be distinguished by the naked eye. This technology is fundamentally different from the "rivulet (shark skin) process," which is known as a typical aerodynamic drag reduction technology. The rivulet process mimics the fine longitudinal grooves in shark skin, and by carving grooves approximately 0.1 mm wide along the direction of airflow, it aligns the vortices that occur near the wall surface of turbulent airflow areas. DMR, on the other hand, delays the switch from laminar to turbulent flow by means of random and minute irregularities. The flow zones it affects and the mechanisms it employs are based on completely different concepts.

Windows' Classic 3D Space Cadet Pinball Is Getting a Physical Re-Creation

Hobbyist CNCDan is trying to build a real-world version of Windows' classic 3D Pinball for Windows -- Space Cadet, using 3D-printed flippers, bumpers, LEDs, slingshots, and a raised playfield modeled after the original virtual table. But in bringing the digital table into the real world, CNCDan has already run into several physical challenges the software never had to contend with... Ars Technica reports: After scaling and skewing the on-screen, perspective-shifted view of the Space Cadet playfield onto a 1-meter-tall table, he ended up with a rectangular playfield just 56 cm wide. That's on the smaller side for commercial pinball tables and maps to playfield bumpers that are just 53 mm wide -- way smaller than any prebuilt bumpers that are commercially available. Once CNCDan dealt with issues with unreliable plastic microswitches for those tiny bumpers (Hall effect magnets seemed to help), he ran into a separate problem with the even smaller bumpers on the raised playfield. The wiring for those bumpers had to be arranged very carefully to avoid blocking a kickback return alley underneath, a positioning problem that the original designers of the virtual table didn't have to consider at all. CNCDan also ended up adding a physical mechanism to simulate the short delay 3D Space Cadet players may remember, when the ball dropped down a hole from the raised playfield back to the flippers below. CNCDan says he's currently looking for artists to help him with a hand-drawn re-creation of the original Space Cadet playfield, which he doesn't want to use AI for. "I'm sure [AI] can do it, but I'd much rather give this job to a real human being," he said in the video.

Sailfish OS reviews are always the same

João Carrasqueira at XDA Developers has taken a look at the current state of Sailfish OS, and concludes: As an idea, I love Sailfish OS. Not only does it bring a wholly unique interface to mobile devices at a time when things seem more unified than ever, but it also has the potential to bring the full power of Linux to a smartphone you actually want to use. But the lack of apps makes it hard for it to become anyone's daily driver, and the power of Linux is somewhat hampered because it relies on dedicated repositories that, again, don't get much support. The community as a whole would benefit if the UI for Sailfish OS could also be open-sourced and made available as a desktop environment other distros could adopt. I can see a world where many more Linux distros might be ported to mobile devices using this UI, and leading to more apps being ported to the platform as well. It's unlikely, but taking that step could make a big difference. ↫ João Carrasqueira It seems like Sailfish OS, much like any other mobile operating system that isn't Android or iOS, is still stuck in application hell, where they've always been. Windows Phone, BlackBerry 10, postmarketOS, Sailfish OS - they all suffer from the fact that the services and associated applications people actually need to use in their day-to-day life just simply aren't there, and never will be unless something utterly drastic happens. You're pretty much forced to fall back on possible Android application compatibility layers, at which point you're basically just running Android in an worse way. As an extremely early customer of the original Jolla Phone, and owner of the very rare Jolla Tablet, I considered if I should add the new Jolla Phone as an incentive for the current fundraiser, but I decided against it because I already know what the review is going to be like. Interesting user interface, very limited set of often buggy native applications, constant reliance on often buggy Android compatibility layer, €750 is a lot of money for a barely mid-range phone. Oh, and the UI layer is closed source. I don't need an expensive phone I won't use after the review period to write any of that. There's very little new to write about or discover when it comes to mobile operating systems other than Android and iOS, and that's not through the fault of the people developing these platforms. All the smart developers working on postmarketOS, Salfish, Ubuntu Touch, and others are doing a great job and the very best they can, but in the end these platforms are limited by the fact that the services we all depend on just do not work on any of them. I don't have the solution for the problem - other than very heavy-handed regulation to demand open APIs, which I support but will never happen - so the status quo will remain as it is. It's a sad state of affairs when even Google-free Android is almost a non-starter at this point.

The Nokia N8 has a brand new, modern, actively maintained, and regularly updated Symbian ROM

I have a Nokia N8, and it's one of my favourite retro (?) devices I own. It was one of Nokia's last efforts to make Symbian happen in the post-iPhone era, and while the hardware was quite nice, Symbian just wasn't made for multitouch devices. It didn't move the needle much for an already dying Nokia, and things just got worse from there. A bright spot with the Nokia N9, some decent Windows Phone devices, and then the end. We all know the story. The Nokia N8, though, seems to have been given a new lease on life recently. This smartphone, released in 2010, can be turned into a usable, capable device again, thanks to a brand new, modern custom Symbian ROM called Reborn. It takes the latest stock Symbian version for the N8, removes any and all applications/links/etc. that don't work anymore, and then proceeds to make a ton of things work again. Modern TLS for HTTPS support, updated certificates, modern email support, a brand new application store, a new update application with a steady stream of OTA updates to fix issues, a bunch of security fixes, a whole slew of quality-of-life touches, and so, so much more. This is absolutely amazing work. Clearly a labour of love, there's already been tons of updates over the past year since the ROM's initial release, and I obviously can't not install this on my own N8, assuming it still works. A video by Janus Cycle covering the project is also available, for the more visually-oriented among us.

Microsoft continues beating the “agentic” Windows drum

We're a mere €124 away from the first incentive during our fundraiser: making me use stock Windows 11 for a month. Since the writing appears to be on the wall, and the donation pulling us across the line can come in any moment, I figured I'd better take a peek at how things stand with Windows. I came across a story about Yusuf Mehdi, an executive vice president and consumer chief marketing officer, who apparently became the face of Microsoft's "AI" push. After 35 years, he's leaving the company, but not after pledging to continue pushing "AI" deeper into Windows 11. Despite this intense backlash, Mehdi is doubling down on the AI vision during his final months at the company. In his LinkedIn announcement, he stated: "I will work through the next fiscal year to help reimagine Windows for the agentic era, grow Microsoft 365 services, and bring our One Copilot vision to life." Microsoft has recently scaled back on some intrusive Copilot features in Notepad, Snipping Tool, and Photos, but the executive leadership team still views AI agents as the inevitable future of the Windows desktop experience. ↫ Abhijith M B at Windows Latest The numbers for Microsoft and every other software company who dove head-first into "AI" are clear: it's one of the biggest bottomless pits of all time, and they're all throwing money down the pit hoping it'll eventually fill up and overflow. Meanwhile, 100 metres down in the pit, a dude in a leather jacket is holding out a bucket and collecting some of the money before it disappears into the void below. For Microsoft, "AI" represents a $235 billion loss (so far!), so the company had to do something - anything - to stop the bleeding. They tried shoving Copilot buttons in every nook and cranny of its products, but users rightfully and understandably revolted. They're toning it down in Windows, and recently, they've also had to tone it down in Office as users were horrified to discover a floating Copilot button in Word, Excel, and so on. People really do not want this shit, which puts these companies in a hugely precarious position: just how badly can they abuse the geese? We'll see just how much Microsoft will actually roll back its force-feeding practices, and I'm not excited to be partaking in the Windows 11 experiment soon.
