1. Mobile carriers can get your GPS location
Total comment counts : 35
Summary
Apple’s iOS 26.3 adds a privacy feature that limits precise location data shared with cellular networks to devices with Apple’s 2025 in-house modem. While cell towers give rough location, 2G–5G protocols (RRLP/LPP) can request GNSS coordinates (GPS, GLONASS, etc.), enabling meter-level accuracy and remaining largely invisible to users. GNSS data normally stays on-device, but these control-plane protocols allow carrier access. Past uses by DEA and Shin Bet highlight privacy risks. The author urges Apple to disable GNSS responses to carriers and notify users when such requests occur, noting potential state-actor abuse.
Overall Comments Summary
- Main point: The discussion centers on pervasive location data collection by carriers, devices, and governments, and how individuals can control or be protected against it, including exploring mesh-based alternatives.
- Concern: The main worry is that location data is harvested, stored, and monetized with little protection or accountability, enabling surveillance and misuse.
- Perspectives: Views range from calling for retroactive privacy protections and real accountability, to accepting that data access by carriers and advertisers is pervasive, to promoting decentralized mesh networks to reduce centralized data collection.
- Overall sentiment: Mixed
2. Genode OS is a tool kit for building highly secure special-purpose OS
Total comment counts : 5
Summary
Genode OS Framework is a toolkit for building secure, purpose-built operating systems. It uses a recursive sandbox model where every program runs in a dedicated sandbox and can create sub-sandboxes, forming hierarchies with policy controls at each level to shrink the attack surface. It blends L4-like principles with Unix philosophy, offering small, composable building blocks—including kernels, drivers, file systems, and protocol stacks. It supports x86, ARM, and RISC-V, with L4 family kernels, Linux, or a custom kernel. Virtualization options include VirtualBox on NOVA and ARM VMM. Open source and commercially supported by Genode Labs, with 100 components.

4. Outsourcing Thinking
Total comment counts : 2
Summary
The post examines whether using large language models to ‘outsource thinking’ harms our cognitive skills and communication. Building on Andy Masley’s lump of cognition fallacy, the author argues that outsourcing thinking isn’t simply about reducing effort: it can reshape what we think about, and who we are when we speak. The piece discusses which activities are more likely to be detrimental, highlighting deception in communication and the erosion of authentic self-expression when machine-generated language replaces human words. While agreeing with Masley on some points, the author broadens the scope and invites reflection on the many, nuanced implications of LLM use.
Overall Comments Summary
- Main point: The commenter questions the value of do-not-use-for-AI lists, argues people will misuse AI under enormous economic and professional pressures, and notes AI changes cognitive load.
- Concern: The main worry is that safeguards may be ineffective against irresponsible AI use and that AI could increase cognitive load and reduce attention.
- Perspectives: One view dismisses cautionary AI-use lists as quaint and assumes people will act responsibly, while the commenter also shares personal experiences of higher cognitive load and more skimming when using AI.
- Overall sentiment: Mixed
5. Claude Code is your customer
Total comment counts : 11
Summary
AI-native, as Claude Code shows, means APIs designed for agents, not just human users. The author argues true AI-native SAAS has been 24 years in the making and will hinge on well-documented APIs that AI agents can read and act on in real time. By 2026 an API-first product is essential; by 2030 any product without an agent-friendly API will die. Commenda exemplifies this with an API-centric SAAS. Bezos’ API Mandate anticipated external interfaces; today Claude Code chooses services by docs, not landing pages. Poor docs and opaque auth kill wins; agent-first APIs win.
Overall Comments Summary
- Main point: The discussion centers on evaluating the practicality and impact of AI agents (e.g., Claude Code) in tasks like reading docs, choosing products, and shaping AI-native startup strategies.
- Concern: The main worry is that relying on agents for complex decisions may be unreliable, overlook regulatory and human-judgment constraints, and misjudge the pace of adopting legacy systems.
- Perspectives: Some participants see potential in agents enabling API-first products and agent-enabled workflows, while others are skeptical about their usefulness for vendor selection and question the inevitability of an API-driven future.
- Overall sentiment: Mixed
6. Show HN: Minimal – Open-Source Community driven Hardened Container Images
Total comment counts : 5
Summary
Chainguard’s Minimal CVE Hardened container image collection provides production-ready images with minimal CVEs, rebuilt daily using apko and Wolfi to reduce attack surface. Some images (HTTPD, Jenkins, Node.js) may include shell via transitive dependencies; CI treats this as informational. All builds pass a CVE gate (no CRITICAL/HIGH vulnerabilities) before publishing, and images are cosign-signed via Sigstore. Verification: replace minimal-python with any image name to confirm CI-built, untampered images. Licensed under MIT; images include Wolfi and other licenses with full details in each image’s SBOM.
Overall Comments Summary
- Main point: The discussion centers on how hardened container images can be used in practice, how to integrate them into CI/CD pipelines, and how to keep them up-to-date with CVEs, while weighing open-source sustainability versus vendor SLAs.
- Concern: The major worry is sustaining timely CVE patching and SLA commitments in an open-source effort, given the breadth of images to cover and profitability challenges.
- Perspectives: Opinions vary from optimism about practical use and automation to requests for pipeline integration details, acknowledgment of vendor offerings and free hardened images, and caution that guaranteeing SLAs in open source may be difficult.
