| 1. | Loupe – A iOS app that raises awareness about what native apps can see(github.com) |
| 295 points by Cider9986 23 hours ago | 113 comments | permalink | |
tl;dr: Loupe is an open-source iOS/iPadOS app (built almost entirely with AI coding tools) that reveals what device fingerprinting data any third-party app can access via public iOS APIs. It organizes readings into three tiers—Passive (no prompt), Needs Permission, and Advanced side-channel techniques like `canOpenURL` probing and Keychain persistence across reinstalls. All data stays on-device, and the project is made by Mysk as a companion to their privacy-focused Psylo browser. | |

| 2. | Renting a sewing machine from the library(bbc.com) |
| 237 points by sohkamyung 12 hours ago | 126 comments | permalink | |
tl;dr: Finnish libraries have evolved beyond books into community hubs lending sewing machines, 3D printers, tennis rackets, and bookable spaces, with Finland spending €66 per capita on libraries—roughly five times the UK and US. Backed by law requiring libraries to promote democracy and active citizenship, they function as inclusion infrastructure, helping users navigate digital bureaucracy and consistently returning $3-5 in value per dollar invested. Researchers argue libraries are among the few remaining trusted public spaces where people can exist without consuming. | |

tl;dr: SMPTE has made its entire Standards catalog—including all published Standards, Recommended Practices, Engineering Guidelines, and RDDs, plus future releases—freely available to the public. The move is backed by Diamond-level corporate members (Apple, Google, Disney, Sony, AWS, etc.) and accompanies a modernization push that includes GitHub-based workflows, HTML-based authoring, and an integrated publishing pipeline. The goal is to improve interoperability and adoption as the industry navigates IP-based workflows, AI authenticity, and content provenance. | |

| 5. | UHF X11: X11 Built for VisionOS and Apple Vision Pro(lispm.net) |
| 205 points by zdw 18 hours ago | 41 comments | permalink | |
tl;dr: UHF X11 turns the Apple Vision Pro into a full X11 display server, rendering each top-level X client as its own rootless spatial window in visionOS. It accepts TCP connections from external X clients with MIT-MAGIC-COOKIE-1 authentication, supports custom bitmap fonts, and includes experimental indirect GLX for OpenGL apps. Retro flair comes via CRT scanlines, phosphor masks, glow, and vignette effects. | |

tl;dr: A hobbyist reverse-engineering the 1989 DOS game F-15 Strike Eagle II has finished reconstructing the C source code for all executables, far ahead of schedule. The project (v0.9.1) is now seeking testers to drop the rebuilt binaries into an original game install (version 451.03 with Desert Storm expansion) and report crashes, graphical glitches, or input issues. Since it's a bug-for-bug reconstruction, testers should verify reported issues aren't also present in the original game. | |

tl;dr: After six years and 362 commits, Linux 7.2 has fully removed the strncpy() API from the kernel, which was long deprecated due to bug-prone NUL termination semantics and performance overhead from redundant zero-filling. Developers should now use replacements like strscpy(), strscpy_pad(), strtomem_pad(), memcpy_and_pad(), or plain memcpy() depending on the use case. | |

| 8. | Temporary Cloudflare accounts for AI agents(blog.cloudflare.com) |
| 212 points by farhadhf 1 day ago | 112 comments | permalink | |
tl;dr: Cloudflare now lets AI agents deploy Workers without signing up first, via a new `wrangler deploy --temporary` flag that provisions a throwaway account valid for 60 minutes. Wrangler's CLI output advertises the flag so agents discover it autonomously, and humans can later "claim" the temporary account (including its Workers, databases, and bindings) by signing in, or let it auto-delete. It's part of a broader push—alongside partnerships with Stripe and WorkOS's auth.md—to remove signup friction for agentic deployments. | |

| 9. | The Wholesale Plagiarism of Obscure Sorrows(waxy.org) |
| 371 points by ridesisapis 17 hours ago | 147 comments | permalink | |
tl;dr: A San Francisco marketing agency called Qontour built an unauthorized website republishing the entire text of John Koenig's book "The Dictionary of Obscure Sorrows," replacing his original illustrations with DALL-E images and adding a GPT-4 word generator, all monetized with their own Amazon affiliate code. The bootleg site now outranks Koenig's official site in Google, ChatGPT, and Gemini, which incorrectly attribute it to him—and Simon & Schuster's DMCA takedowns have had no effect. The author frames this as an egregious example of a broader trend of AI-driven plagiarism displacing original creators. | |

| 10. | GPT-5.5 hallucinates 3x more than MIT-licensed GLM-5.2(arrowtsx.dev) |
| 527 points by oshrimpton 1 day ago | 253 comments | permalink | |
tl;dr: Despite being roughly half the size, the MIT-licensed GLM-5.2 scores within 4 points of GPT-5.5 on the Artificial Analysis Intelligence Index while hallucinating far less (28% vs 86%), suggesting raw parameter scaling has plateaued and may actively harm truthfulness. The author argues massive models like DeepSeek V4 Pro (94% hallucination rate) fail to recognize their own knowledge limits, wasting compute confidently producing wrong answers. Model training and selection should instead optimize a trilemma of capability, hallucination rate, and compute efficiency. | |

| 14. | Where to Find the Colors Your Screen Can't Show You(moultano.wordpress.com) |
| 460 points by moultano 1 day ago | 119 comments | permalink | |
tl;dr: Most screens (sRGB and Display-P3) can't reproduce huge swaths of the visible color space, particularly intense cyans, because the gamut is constrained by the phosphors and primaries chosen decades ago. The author shows where to find these "impossible" colors in real life: light filtered through forest canopies, shallow tropical water, iridescent bird feathers and butterfly wings, bioluminescent dinoflagellates, UV-lit scorpions, and—most accessibly—the LED "green" traffic light, which is actually a vivid turquoise outside any screen's gamut. | |

tl;dr: Hyundai is buying SoftBank's remaining 9.65% stake in Boston Dynamics for $325 million, making the robotics firm a wholly owned subsidiary. The move positions Hyundai to deploy Boston Dynamics' Atlas humanoid robot at its Georgia EV plant by 2028, starting with parts sequencing before scaling to heavier tasks by 2030, with Hyundai Mobis already producing Atlas actuators. SoftBank, meanwhile, is redirecting focus toward Roze AI, a new AI infrastructure venture targeting a $100 billion valuation. | |

tl;dr: The author encoded a small HTML page (208 bytes) into the RGB channels of a 9x9 pixel favicon, prepending a 4-byte length header so a decoder knows where the payload ends. On page load, JavaScript draws the favicon to a canvas, reads the pixels back, and reconstructs the HTML — though a bootstrap loader is still required, making it a curiosity rather than anything practical. | |

| 313 points by Pamar 3 days ago | 146 comments | permalink | |
tl;dr: The 3-30-300 rule, proposed by Cecil Konijnendijk and adopted by cities like Florence and Fort Collins, states every home should have a view of 3 trees, 30% neighborhood tree canopy, and a park within 300m. A study of 862 European cities found only 14% of residents meet all three criteria, with the 30% canopy requirement being the hardest to satisfy. Globally, of eight major cities tested, only Singapore passed — a problem with real consequences, since hitting the 30% target alone could prevent thousands of European heat deaths annually. | |

| 526 points by danabramov 1 day ago | 302 comments | permalink | |
tl;dr: ATProto doesn't have "instances" like Mastodon because it deliberately decouples hosting from apps—your data lives in swappable personal hosting (a PDS), while apps merely aggregate over everyone's data, similar to how RSS feeds relate to readers like Google Reader. This avoids Mastodon's fiefdom problem where your identity is tied to a specific server, federation can break between admins, and your account dies if the instance goes down. Decentralization in ATProto is measured by hosting portability and app diversity, not instance count. | |
