6. Apple Releases iOS 18 Security Updates for iOS 26 Holdouts

Apple Releases iOS 18 Security Updates for iOS 26 Holdouts β€” daringfireball.net Β· 18h ago Β· ⭐ 24/30 Apple initially faced criticism for withholding iOS 18 security updates from iPhones capable of running iOS 26, potentially leaving users who preferred not to upgrade vulnerable. Previously, iOS 18 security updates were exclusively for devices unable to run iOS 26. However, as of April 1, Apple has begun pushing iOS 18.7.7 to all devices running iOS 18, including those compatible with iOS 26. This policy change ensures that users can receive critical security patches without being forced to upgrade to the latest operating system. Apple has thus addressed the security gap for users opting to remain on iOS 18, providing essential updates independently of an OS upgrade. 🏷️ iOS Security, Apple, Security Updates, Policy β€”

Pluralistic: EU ready to cave to Trump on tech (04 Apr 2026) β€” pluralistic.net Β· 6h ago Β· ⭐ 24/30 The article critically suggests that the European Union is poised to concede to potential demands from a Trump administration regarding tech policy, particularly concerning tariffs. It highlights a perceived vulnerability of the EU to external pressures, framing it as a potential β€˜digital subjugation.’ The brief entry points to broader issues like β€˜the trouble with tariffs’ and other critical observations on current events. The main takeaway is a pessimistic view on the EU’s ability to maintain its digital sovereignty against US geopolitical influence. 🏷️ EU Tech Policy, Trump, Tech Regulation, International Relations β€”

What does Open Source mean? β€” nesbitt.io Β· 4h ago Β· ⭐ 21/30 The article’s title and subtitle, β€˜A stack of incompatible expectations,’ introduce the core problem of diverse and often conflicting understandings surrounding the term β€˜Open Source.’ Without further content, the piece implies that the definition and implications of open source software are subject to varied interpretations. It suggests that stakeholders often approach open source with different assumptions and requirements. The main conclusion is that the concept of Open Source lacks a universally agreed-upon interpretation, leading to potential misunderstandings. 🏷️ Open source, expectations, FOSS β€”

15. Roman moon, Greek moon

Roman moon, Greek moon β€” johndcook.com Β· 21h ago Β· ⭐ 14/30 The article clarifies the etymology and interchangeable usage of the terms β€˜perilune’ and β€˜periselene’ in celestial mechanics, prompted by their use in describing the Artemis II mission. β€˜Perilune’ refers to the point of closest approach to the moon, which for Artemis II occurs on the side opposite Earth. Both β€˜perilune’ and β€˜periselene’ are synonymous, with β€˜lune’ deriving from Latin (Roman) and β€˜selene’ from Greek, both meaning moon. The article concludes by explaining that these terms are used interchangeably based on their distinct linguistic origins, providing clarity for lunar orbital terminology. 🏷️ Perilune, Periselene, Artemis II, etymology β€” Generated at 2026-04-04 14:04 | Scanned 78 sources -> 2388 articles -> selected 15 Based on the Hacker News Popularity Contest 2025 RSS source list recommended by Andrej Karpathy Produced by Dongdianr AI.
