A study this week has found that shoppers using Instacart are often charged different prices for identical products at the same store at the same time, even when selecting in-store pickup rather than delivery. The Groundwork Collaborative, a progressive policy group, and Consumer Reports organized nearly 200 volunteers across four cities to simultaneously check prices on 20 grocery items. Price differences appeared on nearly three-quarters of the items tested. In one test, more than 40 participants selected the same Safeway in Washington, D.C. and the same brand of eggs. Prices ranged from $3.99 to $4.79 -- a 20% spread. At a Target in North Canton, Ohio, Skippy peanut butter was $2.99 for some shoppers and $3.59 for others. The full 20-item basket varied by about 7% within each store. An Instacart spokeswoman said retailers on its platform set their own prices and that some run short-term, randomized pricing tests. The company said tests were "never based on personal or behavioral characteristics." Instacart acquired Eversight, an AI-driven pricing optimization company, in 2022. A Target spokesman said the company is not affiliated with Instacart and bears no responsibility for prices on the platform. Safeway and parent company Albertson's declined to comment.

Nvidia has developed location verification technology that could determine which country its AI chips are operating in, Reuters reports, citing a source, a capability that may help address ongoing concerns about the smuggling of advanced semiconductors to restricted markets like China. The feature, which Nvidia has demonstrated privately in recent months but has not released, would be an optional software tool that customers install. It taps into the confidential computing capabilities of Nvidia's GPUs and uses the time delay in communicating with Nvidia-run servers to approximate a chip's location. The technology will first be available on Nvidia's newest Blackwell chips, though the company is examining options for its older Hopper and Ampere generations. U.S. lawmakers and the White House have pushed for location verification measures as the Department of Justice has brought criminal cases against smuggling rings allegedly attempting to move more than $160 million worth of Nvidia chips to China.

McDonald's has pulled an AI-generated Christmas commercial from YouTube after viewers pushed back on what they called a distasteful, "AI slop"-filled take on the holidays. The 45-second ad, titled "It's the most terrible time of the year," was a satirical look at holiday chaos -- people tripping while carrying overloaded gift bags, getting tangled in lights, burning homemade cookies, starting kitchen fires -- and ended with a suggestion to ditch the madness and hide out at McDonald's until January. The ad was created for McDonald's Netherlands by agency TBWA\NEBOKO and production company Sweetshop, whose Los Angeles-based directing duo Mark Potoka and Matt Spicer shot the film. After the backlash, Sweetshop said it used AI as a tool but emphasized human effort in shaping the final product. "We generated what felt like dailies -- thousands of takes -- then shaped them in the edit just as we would on any high-craft production," the company said. "This wasn't an AI trick. It was a film."

If you're old enough, you no doubt remember that up until the 2.6.0 release of the Linux kernel, an odd number after the first version number indicated a pre-release, development version of the kernel. Even though this scheme was abandoned with the 2.6.0 release in 2003 and since then every single release has been a stable release, it seems the ghosts of this old versioning scheme still roam the halls, because prominent Linux kernel developer Greg Kroah-Hartman just published an explainer about Linux kernel versions. Despite having a stable release model and cadence since December 2003, Linux kernel version numbers seem to baffle and confuse those that run across them, causing numerous groups to mistakenly make versioning statements that are flat out false. So let's go into how this all works in detail. ↫ Greg Kroah-Hartman I genuinely find it difficult to imagine what could possibly be unclear about Linux kernel version numbers. The Linux kernel uses a very generic major.minor scheme, but that's not where the problems lie - it's the actual development process of each of these numbered release that's a bit more complex. This is where we have to talk about things like the roughly 10-week release cycle, containing a 2-week merge window, as well as Torvalds handing off the stable branch to the stable kernel maintainers. The other oddity is when the major version number gets incremented - the first number in the version number. There's no real method to this, as Kroah-Hartman admits Torvalds increments this number whenever the remaining numbers get too high and unwieldy to deal with. Very practical, but it does mean that going from, say, 5.x to 6.x doesn't really imply there's any changes in there that are any bigger or more disruptive than when going from 6.8.x to 6.9.x or whatever. There's a few more important details in here, of course, like where LTS releases come from, but that's really it - nothing particularly groundbreaking or confusing.

With the current, rapidly deteriorating state of the Windows operating system, you have to take the small wins you can get: Microsoft is now offering the option of removing "AI" actions from Windows 11's context menus. buried deep in the Windows 11 Insider Preview Build 26220.7344 release notes, there's this nugget: If there are no available or enabled AI Actions, this section will no longer show in the context menu. ↫ Windows Insider Preview release notes If you then go to Settings > Apps > Actions and uncheck all the "AI" actions, the entire submenu in Windows 11's context menus will vanish. While this is great news for those Windows users who don't want to be bothered by all the "AI" nonsense, I wish Microsoft would just give users a proper way to edit the context menu that doesn't involve third party hackery. KDE's Dolphin file manager gives me full control over what does and does not appear in its context menu, and I can't imagine living without this functionality - there's so many file-related operations I never use, and having them clutter up the context menu is annoying and just slows me down. There's more substantial and important changes in this Insider Preview Build too, most notably the rollout of the Update Orchestration Platform, which should make downloading and installing application updates less cumbersome, but since it's a new feature, application won't support it right away. This release also brings the new Windows MIDI Services, and Microsoft hopes this will improve the experience for musicians using MIDI 1.0 or MIDI 2.0 on Windows. There's a slew of smaller changes, too, of course. I'm not exactly sure when these new features will make their way to production installations - who does, honestly, with Microsoft's convoluted release processes - but I hope it's sooner rather than later.

When Mac OS X was designed, it switched to the bundle structure inherited from NeXTSTEP. Instead of this multitude of resources, apps consisted of a hierarchy of directories containing files of executable code, and those with what had in Mac OS been supporting resources. Those app bundles came to adopt a standard form, shown below. ↫ Howard Oakley A short, but nonetheless informative overview of the structure of a macOS application. I'm sure most people on OSNews are aware that a macOS application is a bundle, which is effectively a glorified directory containing a variety of files and subdirectories that together make up the application. I haven't used macOS in a while, but I think you can right-click on an application and open it as a folder to dig around inside of it. I'm trying to remember from my days as a Mac OS X user - 15-20 years ago - if there was ever a real need to do so, but I'm sure there were a few hacks you could do by messing around with the files inside of application bundles. These days, perhaps with all the code-signing, phoning-home to Apple, and other security trickery going on, such acts are quite frowned upon. Does making any otherwise harmless changes inside an application bundle set off a ton of alarm bells in macOs these days?

Over the course of 2025, every single major cloud provider has failed. In June, Google Cloud had issues taking down Cloud Storage for many users. In late October, Amazon Web Services had a massive outage in their main hub, us-east-1, affecting many services as well as some people's beds. A little over a week later Microsoft Azure had a [widespread outage][Azure outage] that managed to significantly disrupt train service in the Netherlands, and probably also things that matter. Now last week, Cloudflare takes down large swaths of the internet in a way that causes non-tech people to learn Cloudflare exists. And every single time, people share that one XKCD comic.

After Gandi was bought up and started taking extortion level prices for their domains I've been looking for an excuse to migrate registrar. Last week I decided to bite the bullet and move to Porkbun as I have another domain renewal coming up. However after setting up an account and paying for the transfer for 4 domains, I realized their DNS services are provided by Cloudflare! I personally do not use Cloudflare, and stay far away from all of their products for various reasons.

The waydroid package prior to version 1.5.4-2 (including aur/waydroid) creates Python byte-code files (.pyc) at runtime which were untracked by pacman. This issue has been fixed in 1.5.4-3, where byte-compiling these files is now done during the packaging process. As a result, the upgrade may conflict with the unowned files created in previous versions. If you encounter errors like the following during the update:

error: failed to commit transaction (conflicting files) waydroid: /usr/lib/waydroid/tools/__pycache__/__init__.cpython-313.pyc exists in filesystem waydroid: /usr/lib/waydroid/tools/actions/__pycache__/__init__.cpython-313.pyc exists in filesystem waydroid: /usr/lib/waydroid/tools/actions/__pycache__/app_manager.cpython-313.pyc exists in filesystem

You can safely overwrite these files by running the following command: pacman -Syu --overwrite /usr/lib/waydroid/tools/\*__pycache__/\*
