Longtime Slashdot reader BeaverCleaver shares a report from the BBC: The wreckage of a Pan American Airways plane has been found 74 years after it plunged into the Atlantic Ocean in a crash that prompted mandatory airline safety briefings. The Clipper Endeavor was found 2,000ft (610m) below sea level off the coast of Puerto Rico with a sonar-equipped drone. It went down on April 11, 1952, following multiple-engine failure shortly after take-off. Everyone onboard survived the impact -- but passengers struggled to locate life vests and rafts as the plane rapidly sank. Of the 69 passengers and crew onboard, just 17 survived. The disaster led to sweeping reforms in aviation safety, including compulsory pre-flight safety briefings on every commercial flight. [...] Today, before every commercial flight, cabin crew are required to outline where a plane's exits are, as well as the location of life vests and how to inflate them.

Most Linux teams don't struggle to find vulnerabilities anymore. They struggle to decide which ones deserve attention first. Between daily scanner results, vendor advisories, and hundreds of new CVEs each month, the challenge isn't visibility—it's prioritization.

When Felipe first emailed us about the GUADEC 2026 travel grant, we were thrilled to learn that we were going to have the opportunity to attend the conference in person.

This was my first GUADEC, and it was a pleasure to meet the GNOME community and put faces to names. The conference was held in A Coruña, Spain, which turned out to be an amazing city with great food, friendly people, and beautiful views along the coast.

Community

The first thing I would like to mention was how patient and open the community was to both my fiancée Laureen and me. We knew going into the conference that we were much more junior than many of the developers attending, but everyone was incredibly approachable.

I received a great deal of help debugging issues in my local development environment, as well as guidance on some of the more difficult parts of my GSoC project.

Talks

The talks were very informative and I took way too many notes to include them all here without turning this into a novel. That said, I wanted to write a short summary of a couple of talks that I found interesting:

Varlink for System Components

Sebastian Wick gave a talk about modernizing the system component stack. His proposed idea for allowing more memory safety and zero cost abstractions was to write components in Rust, however this introduces the issue of introspection. For asynchronous functionality, Tokio and Glib both have main loops, and moving data between the loops can introduce a lot of overhead. GObject bindings can also make Rust's memory safety essentially moot.

Sebastian spoke about potentially not using GObject in some cases, and instead exposing more functionality over IPC using Varlink. Varlink is language agnostic, and services could be consumed from many languages without requiring GObject bindings. This process also would be very simple, allowing signals to occur as JSON strings that are easily observable. This would require some new crates to replace Glib functionality, and some more complicated functionality like file thrashing and sftp could be particularly difficult.

It is early, the ecosystem is still being built, but Sebastian argued that usage patterns will evolve and getting involved now will help shape the future of GNOME and Rust.

Using GTK in C++ with Peel

Sergey Bugaev hosted a workshop on using GTK from C++ with Peel. Peel is a library that allows you to use GTK in C++ to make GTK applications and widgets. Sergey made a simple widget that can draw using stylus input, and he walked us through the process of creating a simple application using Peel. The workshop was very informative.

I really regret not coding his example myself, I wish a recording of the lecture had been taken. That said, his repo can be found at https://gitlab.gnome.org/bugaevc/peel and his readme has instructions for usage and a basic code example.

Debugging with Tracy

Ivan Molodetskikh gave a talk that seemed really handy to me about using Tracy to profile performance for Mutter, GNOME shell, and applications. I had never heard of Tracy before this talk, however the capabilities seemed very handy. Tracy visualizes "zones" on a timeline, allowing you to see exactly where execution time is being spent across threads. The Tracy zones must nest correctly, where parent zones cannot end before their child zones. It can also show where threads are waiting. This allows for a very clear visualization of where time is being spent in the application, and can help identify bottlenecks or bugs.

The major downside to Tracy is that it requires a lot of setup, and the application must be compiled with the Tracy client library. Ivan gave a fairly in-depth breakdown of how to add Tracy profiling to an application, and I will go back to the recording of his talk to actually implement it in the future.

Technical Take Aways for My Project

• Sergey Bugaev helped me get the GIR generation for my C API working correctly. We also improved the FFI by exposing PitiviTimelineRuler directly in the public header rather than accepting a generic GtkWidget* and performing a runtime type check. This makes the API more type-safe and simplifies the Rust implementation. The GIR generation currently works after calling gtk::init() from pitivi_timeline_ruler_get_type(), but Sergey pointed out that this approach will likely fail in CI because the generated scanner shouldn't require GTK to be initialized this way. I'm still trying to build a solid mental model of how GIR generation and introspection work, so if anyone has experience with bindings, I'd love to hear your thoughts.

• Federico also spent some time reviewing my project with me. He suggested refactoring PitiviTimelineRuler so all of the mutable drawing state lives inside a single RefCell rather than several individual ones, I think the result would look something like this:

#[derive(Default)] struct DrawingState { cache: BTreeMap<...>, font: Option<...>, handler_id: Option<...>, } #[derive(Properties)] #[properties(wrapper_type = super::MyWidget)] pub struct MyWidget { #[property(get, set)] zoom_level: Cell<u64>, state: RefCell<DrawingState>, } Thanks to GNOME Foundation

I want to give a special thanks to the GNOME Foundation for granting us the travel grant to attend GUADEC 2026. It was a wonderful experience and I look forward to attending future conferences in person!

"General Motors has been pulling a Tim Cook and boosting its software and subscription business," reports Business Insider. During the automaker's Tuesday earnings call, executives said they're increasingly leaning on software subscriptions like OnStar and Super Cruise to generate high-margin recurring revenue long after customers buy their vehicles. GM says OnStar brought in about $800 million in the second quarter, while Super Cruise revenue grew about 70% year over year. From the report: GM says its software business keeps roughly 70 cents of every dollar it brings in. That's a rare level of profitability in the auto industry, as many car sales generate just four to 10 cents per sales dollar. [...] GM expects to add about 1 million OnStar subscribers this year, bringing the total close to 13 million. Super Cruise, GM's hands-free, eyes-on driving system, is growing even faster. GM added about 70,000 subscribers during the quarter and expects to end the year with more than 850,000. Revenue from the service increased about 70% from a year earlier. And a lot of drivers are sticking around after the free period ends. GM said between 30% and 40% of eligible owners continue paying after their included three-year Super Cruise subscription expires. [..] "We do think we have tremendous levers, multiple levers of growth," Barra said on the call. "We definitely think there's a lot of opportunity at GM to grow, improve margins, and become less cyclical." "Software and services are becoming increasingly important to how customers experience GM vehicles and how we deliver value beyond the initial purchase," a spokesperson previously told Business Insider. "As vehicles become more software-defined, we can introduce new digital experiences through updates and optional services rather than hardware changes."

Code found in the iOS 27 beta suggests Apple is developing a system that could restrict leased iPhones when customers fall behind on payments. The discovery follows a recent Bloomberg report that Apple may soon launch a new "Apple Upgrade" leasing program, allowing customers to pay for hardware through monthly installments. 9to5Mac reports: The code describes a system called App Managed Features, which allows an authorized financing or provider app to enroll an iPhone and perform ongoing status checks. If the contract is no longer in good standing, Apple's system services can place the iPhone in "Restricted Mode," which blocks access to most apps until the payment or contract issue is resolved, while keeping a small set of apps available. The fixed allowlist currently found in the iOS 27 beta includes: Accessibility Reader, App Store, Health, Magnifier, Phone, Clock, Settings, Wallet, Passwords, and the Restricted Mode interface itself. Apps that can send critical alerts, such as Messages, Home, and certain medication or safety apps, may also remain accessible. However, the provider appears to have some control over those exceptions. The code does not appear to cancel, suspend, or otherwise modify App Store subscriptions associated with blocked apps. As a result, a subscription could continue billing even while access to its app is restricted. Additionally, there isn't a fixed number of missed payments that automatically triggers the restrictions. The financing provider's app decides when to lock the device based on its own policies. Finally, the new framework also introduces a new type of activation lock called "Partner Finance Lock," which is meant to prevent users from erasing, reselling, or stripping a restricted device for parts.

Ancient Slashdot reader alanw shares a post from the OSS Security mailing list, where sysadmin Jan Schaumann wonders what to do after the Linux kernel cranked out 432 CVEs in a little over 24 hours: "I understand the position that CVEs were always a flawed way to track or prioritize security changes... But this onslaught really shows it's not feasible to attempt to prioritize individual kernel changes. I'm not sure what to do here going forward." The Register reports: The nixCraft team speculated on social media that AI bug reports are a likely reason for all those kernel CVEs, which wouldn't be without precedent - Linus Torvalds himself said in May that the Linux kernel security mailing list had become "almost entirely unmanageable" due to AI-assisted bug hunting. Nonetheless, Torvalds has described AI as a useful tool for Linux development while still noting it can be a drag for maintainers, both from a workload standpoint and the fact "it keeps finding embarrassing bugs." [...] Unfortunately for Linux sysadmins, the position in which they find themselves in this current mess isn't one that's readily solved. CVEs might be a messy way to track and prioritize security updates, especially when hundreds of them are published over a short period, but without something better, it falls to IT and security teams to determine which vulnerabilities affect their systems and which kernel updates they need to deploy. Senior kernel maintainer Greg Kroah-Hartman replied to Jan's post, pushing back on the idea that the kernel's CVE volume is uniquely unmanageable. The kernel isn't special, he argues -- companies everywhere are finally realizing they need to re-evaluate how they update all of their systems and devices, something that's traditionally been "woefully ignored." On the "just always update" approach, Greg says that's precisely what the kernel community endorses: "This is what the kernel developer community recommends and supports. If you want support from us, do this." Can't manage it yourself? Pay a company for support, or "just use Debian or Yocto as their security practices are amazing." He points to Android as proof the approach scales, calling it "the largest deployment of software in the world" -- billions of devices kept updated "with one very-overworked developer guiding it all." As for reviewing every CVE individually, he notes this can be largely automated by intersecting the files a CVE touches with the files you actually build, which typically trims the relevant set "down to about 10% of the overall total" -- the approach enterprise distros already take for their customers. Panic-mode selective patching gets a blunt "Good luck with that!" -- regulations like the EU's Cyber Resilience Act are set to legislate that habit away ("rightfully so," in his view), and "your insurance company might wish to have a talk with you as well." Greg also warns the flood isn't over: "The number of llm-found issues is only on the rise right now, it's going to be a very long 18 months at the least to dig ourselves out of this mess, and people had BETTER be updating their systems all along the way if they expect to be secure in any way." As for the 432-CVE burst itself, he explains it was simply him catching up on a weeks-old, publicly visible review queue over the weekend -- delayed by "a perfect storm of 6 weeks straight of conferences and vacations" -- so it shouldn't have come as a surprise to anyone watching the public git repo.

Apple is reportedly launching a Klarna financing deal that will let U.S. customers spread the cost of devices over up to three years, pushing the company closer to a hardware-as-a-service model. "The only thing you don't get under the new arrangement is AppleCare, for which you'll allegedly need to pay extra," notes Computerworld. From the report: The introduction of the scheme gives consumers a way to purchase the company's popular high-end devices when they are introduced -- no doubt,at higher cost -- this fall. [...] A combination of changed customer habits and external threat means the stars are now aligned for hardware-as-a-service models. "Reframing a device as a low monthly payment protects that [upgrade] cadence and allows Apple to start marketing their products as device-as-a-service to consumers, which no other vendor was ever able to do," [IDC analyst Francisco Jeronimo] wrote to me. There is a one-more-thing aspect to this: the products are effectively being leased, a new approach that will give Apple a stronger grip on EOL devices, helping it grab more of them for refurbishment, resale, and recycling. Over time, this will give the company a much stronger grip on the lucrative second-user market that exists around Apple equipment, even while for almost every consumer product we find the life we want is something we can rent, but probably can't afford to own. The other solid reason to take a partnership approach is risk management. Apple had intended to develop its own buy-now, pay-later scheme via Apple Pay Later, but abandoned that plan as it became riskier with rising bank rates. "Also, by backing the program with Klarna rather than reviving the in-house subscription plan it shelved in 2024, Apple captures the demand upside without taking the credit risk onto its own balance sheet," Jeronimo said. "Apple Upgrade lands at precisely the moment Apple needs it," Jeronimo wrote in a note seen by Computerworld. "Having just pushed Mac and iPad prices up on the back of the memory shortage, with iPhone increases widely expected in September -- as well as the new iPhone foldable expected at $2,500 -- Apple's real risk is that rising prices even further can impact the upgrade cycle."

An anonymous reader quotes a report from Wired: A little over a month after the Department of Defense (DOD) bragged that nearly half of its 3.5 million employees were using AI at work, members of the Army's Combat Capabilities Development Command (DEVCOM) received an email informing them that they were burning through tokens, and needed to limit use. "Although the Army CIO announced in May 2026 that they were offering unlimited tokens, by mid-June the Army CIO pool was exhausted of tokens and had to re-establish limits," the email reads. The email goes on to say that although the Army has chosen to renew token usage at "its current levels," it's unclear "if the Army CIO pool will be renewed after 1 Oct." The Army uses Ask Sage, a multimodal generative AI platform where users can run different large language models (LLMs), including Alphabet's Gemini, Meta's Llama, and OpenAI's ChatGPT. "Apparently the whole Army burned through the whole year of tokens for just one service," says an Army employee who spoke to WIRED [...]. The Army employee says that the Army has been pushing its workers to lean into using generative AI. Employees were given an allotment of at least 200,000 tokens per month, according to emails viewed by WIRED, and were automatically allocated more if they burned through their initial allotment. Employees who had signed up for Ask Sage but were not regularly using it would receive emails encouraging them to use more of their allocated tokens. In order to use Ask Sage, the Army had access to 100,000,000 tokens as part of an annual subscription to an "enterprise pack." Tokens represent a unit of output, either in text or image, from an LLM. For the Ask Sage tool, a single token equates to about 3.7 characters, according to documents viewed by WIRED. The Defense Department burned through some 20 billion tokens per day during the 38-day Operation Epic Fury in Iran, according to Breaking Defense. It's unclear if the tokens used by regular DOD employees are drawn from the same pool as those who might be using AI tools on classified or secret information.

Microsoft has announced Xbox Backward Compatibility for PC, a new preservation program that will let players run select classic Xbox games on Windows PCs and handhelds like the ROG Xbox Ally. Tom's Hardware reports: "This marks the beginning of a broader effort to preserve XBOX games from the past and bring them to PC over time," the company said in a blog post authored by Xbox "VP next generation" Jason Ronald. Alongside backward compatibility, the company says games will also include new features. The four titles in the announcement are: BLiNX: The Time Sweeper; Conker: Live and Reloaded; Crimson Skies: High Road to Revenge; and Fuzion Frenzy. You can now buy all of these games on PC, and they're also included in all Xbox Game Pass plans. Anyone who already owns these titles digitally on console can also now play them on PC or handheld, with support for Xbox Play Anywhere and Xbox Cloud Gaming. Crucially, this appears to be a digital-only preservation effort, so it won't help anyone who only owns physical copies of these games. Xbox has reportedly been testing a way to digitize physical games as far back as Xbox One, but that hasn't yet materialized yet. Alongside the preserved original gameplay, Xbox claims these games will let users customize graphics settings, with up to 4x resolution scaling, VSync support, Fullscreen and Windowed modes, anisotropic filtering, and enhanced anti-aliasing, with more features to come in the future. Notably, Xbox will add achievements to select original Xbox games on console and PC.

At a Galaxy Unpacked event in London today, Samsung unveiled a new foldable smartphone designed to compete with the still-unannounced iPhone Fold. Called the Galaxy Z Fold 8, it features a wider 4:3 form factor with a 7.6-inch inner AMOLED display, Snapdragon 8 Elite Gen 5 for Galaxy chip, up to 16GB of RAM and 1TB of storage. "The inner display has enough extra real estate for multi-tasking and entertainment," reports Mashable, which got a chance to try the new foldable ahead of the event. "And if you're worried about a crease in the middle of the display, don't be. We got up close with the device, and the crease fully disappears when the display is activated." From the report: As stated above, the main distinguishing factor of the new Z Fold 8 is its wider 4:3 proportions compared to the Z Fold 8 Ultra. If the latter is a book-style foldable, the former can almost be called a tablet-style foldable, instead. We think the wide screen will serve even better for reading books or multi-tasking with several apps open at once. Also, at 201g, Samsung is really emphasizing how light the device is. The company is calling it the "world's lightest fold ever." And while the device may be light, its no lightweight. Samsung's newest foldable features Flex Titanium technology, which makes the Galaxy Z Fold 8 more durable. Speaking of durability, it also boasts Samsung's advantage hinge technology, Armor Flexhinge. The Z Fold 8 feels like a solid middle point between the premium Z Fold 8 Ultra and the comparatively affordable Z Flip 8. All three phones use the same chip, but the Z Fold 8's 4,800mAh battery is smaller than that of the Z Fold 8 Ultra. However, the Z Fold 8 does have an option for 16GB RAM and 1TB of storage, similar to the Ultra.
