  • Apple Blocks US Users From Downloading ByteDance's Chinese Apps
    by BeauHD on 06/03/2026 at 10:00 pm

    An anonymous reader quotes a report from Wired: While TikTok operates in the United States under new ownership, Apple has deployed technical restrictions to block iOS users in the United States from downloading other apps made by the video platform's Chinese parent organization ByteDance. ByteDance owns a vast array of different apps spanning social media, entertainment, artificial intelligence, and other sectors. The leading one is Douyin, the Chinese version of TikTok, which has over 1 billion monthly active users. While most of those users reside in China, iPhone owners around the world have traditionally been able to download these apps from anywhere without using a VPN, as long as they have a valid App Store account registered in China. That's not true anymore. Starting in late January, iPhone users in the U.S. with Chinese App Store accounts began reporting that they were encountering new obstacles when they tried to download apps developed by ByteDance. WIRED has confirmed that even with a valid Chinese App Store account, downloading or updating a ByteDance-owned Chinese app is blocked on Apple devices located in the United States. Instead, a pop-up window appears that says, "This app is unavailable in the country or region you're in." The restriction appears to apply only to ByteDance-owned apps and not those developed by other Chinese companies. The timing and technical specifics suggest the restriction is related to the deal TikTok agreed to in January to divest Chinese ownership of its U.S. operations. The agreement was the result of the so-called TikTok ban law passed by Congress in 2024, which also barred companies like Apple and Google from distributing other apps majority-owned by ByteDance. The Protecting Americans from Foreign Adversary Controlled Applications Act states that no company can "distribute, maintain, or update" any app majority-controlled by ByteDance "within the land or maritime borders of the United States." The law was primarily aimed at TikTok, which has more than 100 million users in the U.S. and had been the subject of years of debate in Washington over whether its Chinese ownership posed a national security risk. But ByteDance also has dozens of other apps that at some point were also removed from Apple's and Google's app stores in the U.S.. Now it seems like the scope of impact has reached even more apps that are not technically designed for U.S. audiences, such as Douyin, the AI chatbot Doubao, and the fiction reading platform Fanqie Novel.

  • System76 Comments On Recent Age Verification Laws
    by BeauHD on 06/03/2026 at 9:00 pm

    In a blog post on Thursday, System76 CEO Carl Richell criticized new state laws in California, Colorado, and New York that would require operating systems to verify users' ages and expose that information to apps, arguing the rules are easy for kids to bypass and ultimately undermine privacy and freedom more than they protect minors. "System76's position is interesting given that they sell Linux-loaded desktops, workstations and laptops plus being an operating system vendor with their in-house Pop!_OS distribution and COSMIC desktop environment," adds Phoronix's Michael Larabel, noting that they're also based out of Colorado. Here's an excerpt from the post: "A parent that creates a non-admin account on a computer, sets the age for a child account they create, and hands the computer over is in no different state. The child can install a virtual machine, create an account on the virtual machine and set the age to 18 or over. It's a similar technique to installing a VPN to get around the Great Firewall of China (just consider that for a moment). Or the child can simply re-install the OS and not tell their parents. ... In the case of Colorado's and California's bills, effectiveness is lost. In the case of New York's bill, liberty is lost. In the case of centralized platforms, potential is lost. ... The challenges we face are neither technical nor legal. The only solution is to educate our children about life with digital abundance. Throwing them into the deep end when they're 16 or 18 is too late. It's a wonderful and weird world. Yes, there are dark corners. There always will be. We have to teach our children what to do when they encounter them and we have to trust them." "We are accustomed to adding operating system features to comply with laws," writes Richell, in closing. "Accessibility features for ADA, and power efficiency settings for Energy Star regulations are two examples. We are a part of this world and we believe in the rule of law. We still hope these laws will be recognized for the folly they are and removed from the books or found unconstitutional." Read more of this story at Slashdot.

  • Mozilla Is Working On a Big Firefox Redesign
    by BeauHD on 06/03/2026 at 8:00 pm

    darwinmac writes: Mozilla is working on a huge redesign for its Firefox browser, codenamed "Nova," which will bring pastel gradients, a refreshed new tab page, floating "island" UI elements, and more. "From the mockups, it appears Mozilla took some inspiration from Googles Material You (or at least, the dynamic color extraction part of it) because the browser color accent appears influenced by the wallpaper setting," reports Neowin. "Choosing a mint-green desktop background automatically shifts the top navigation bars to match that exact shade." Mozilla has a habit of redesigning Firefox every few years. Before "Nova," there was the "Proton" redesign in 2021, the "Photon" redesign in 2017, and the "Australis" redesign in 2014. Nova is still in early development, so it might take a year or two before it appears in an official stable Firefox release. Neowin adds: "Not every redesign project ends well for Mozilla, though. You might remember 2012's Firefox Metro, an ambitious attempt to build a custom browser for Windows 8s touch-first interface. The team built it to operate both as a traditional desktop application and as a touch-optimized Metro app. The whole thing was scrapped in 2014 after two years in development due to a dismally low user adoption rate (a preview version of the software had been released a year earlier on the Aurora channel)."

  • Iran War Provides a Large-Scale Test For AI-Assisted Warfare
    by BeauHD on 06/03/2026 at 7:00 pm

    An anonymous reader quotes a report from Bloomberg, written by Katrina Manson: The U.S. strikes on Iran ordered by President Donald Trump mark the arrival on a large scale of a new era of warfare assisted by artificial intelligence. Captain Timothy Hawkins, a Central Command spokesperson, told me last night that the AI tools the U.S. military is using in Iran operations don't make targeting decisions and don't replace humans. But they do help "make smarter decisions faster." That's been the driving ambition of the U.S. military, which has spent years looking at how to develop and deploy AI to the battlefield [...]. Critics, such as Stop Killer Robots, a coalition of 270 human-rights groups, argue that AI-enabled decision-support systems reduce the separation between recommending and executing a strike to a "dangerously thin" line. Hawkins said the military's use of AI assistance follows a rigorous process aligned with U.S. policy, military doctrine and the law. Artificial intelligence helps analysts whittle down what they need to focus on, generating so-called points of interest and helping personnel make "smart" decisions in the Iran operations, he told me. AI is also helping to pull data within systems and organize information to provide clarity. Among the AI tech used in the Iran campaign is Maven Smart System, a digital mission control platform produced by Palantir [...]. That emerged from Project Maven, a project started in 2017 by the Pentagon to develop AI for the battlefield. Among the large language models installed on the system is Anthropic's Claude AI tool, according to the people, who said it has become central to U.S. operations against Iran and to accelerating Maven's development. Claude is also at the center of a row that pits Anthropic against the Department of Defense over limits on the software.

  • Python 'Chardet' Package Replaced With LLM-Generated Clone, Re-Licensed
    by BeauHD on 06/03/2026 at 6:00 pm

    Ancient Slashdot reader ewhac writes: The maintainers of the Python package `chardet`, which attempts to automatically detect the character encoding of a string, announced the release of version 7 this week, claiming a speedup factor of 43x over version 6. In the release notes, the maintainers claim that version 7 is, "a ground-up, MIT-licensed rewrite of chardet." Problem: The putative "ground-up rewrite" is actually the result of running the existing copyrighted codebase and test suite through the Claude LLM. In so doing, the maintainers claim that v7 now represents a unique work of authorship, and therefore may be offered under a new license. Version 6 and earlier was licensed under the GNU Lesser General Public License (LGPL). Version 7 claims to be available under the MIT license. The maintainers appear to be claiming that, under the Oracle v. Google decision, which found that cloning public APIs is fair use, their v7 is a fair use re-implementation of the `chardet` public API. However, there is no evidence to suggest their re-write was under "clean room" conditions, which traditionally has shielded cloners from infringement suits. Further, the copyrightability of LLM output has yet to be settled. Recent court decisions seem to favor the view that LLM output is not copyrightable, as the output is not primarily the result of human creative expression -- the endeavor copyright is intended to protect. Spirited discussion has ensued in issue #327 on `chardet`s GitHub repo, raising the question: Can copyrighted source code be laundered through an LLM and come out the other end as a fresh work of authorship, eligible for a new copyright, copyright holder, and license terms? If this is found to be so, it would allow malicious interests to completely strip-mine the Open Source commons, and then sell it back to the users without the community seeing a single dime.

  • Proton Mail Helped FBI Unmask Anonymous 'Stop Cop City' Protester
    by BeauHD on 06/03/2026 at 5:00 pm

    Longtime Slashdot reader AmiMoJo shares a report from 404 Media: Privacy-focused email provider Proton Mail provided Swiss authorities with payment data that the FBI then used to determine who was allegedly behind an anonymous account affiliated with the Stop Cop City movement in Atlanta, according to a court record reviewed by 404 Media. The records provide insight into the sort of data that Proton Mail, which prides itself both on its end-to-end encryption and that it is only governed by Swiss privacy law, can and does provide to third parties. In this case, the Proton Mail account was affiliated with the Defend the Atlanta Forest (DTAF) group and Stop Cop City movement in Atlanta, which authorities were investigating for their connection to arson, vandalism and doxing. Broadly, members were protesting the building of a large police training center next to the Intrenchment Creek Park in Atlanta, and actions also included camping in the forest and lawsuits. Charges against more than 60 people have since been dropped. Read more of this story at Slashdot.
