AI Summarized Hacker News

PatchGuard on Windows x64 protects key kernel data (SSDT, GDT/IDT, selected system images like ntoskrnl.exe, hal.dll, ndis.sys, and MSRs) by storing checksums, per-processor contexts, and obfuscated, timer-driven validation. Boot-time initialization is triggered indirectly via a divide-error fault from a misnamed KiDivide6432 routine, with debugger presence affecting boot; PatchGuard copies INITKDBG, builds a PATCHGUARD_CONTEXT with function pointers, XOR-encrypts it, then queues a timer DPC whose DeferredContext points to the XOR’d patch context. Validation may be intercepted via exception-handler hooks or KeBugCheckEx hooks, timer-finding hacks, or hybrid schemes. The paper argues this security relies on obscurity; hardware-enforced separation remains work.

Aether is an open-source ISP orchestration lab dashboard for simulating subscriber lifecycles and network topologies. The JD DEMO environment resets every 6 hours or via CI. Traffic is configurable via simulator.config.json and can run in a Vagrant VM. It provides shortcuts to add customers, plans, services, and routers, view topology and sessions, and simulate subscribers connecting via DHCPv4 directly from the dashboard without SSH. Modules include BNG health, real-time session monitoring, and pre-configured access nodes; currently the UI shows zero results in all tables.

ABP (Agent Browser Protocol) is a Chromium-based browser engine with an embedded HTTP server that drives web browsing as a sequence of atomic steps for language models. Each action injects real input, waits for a settled state, and returns a screenshot, events, and state; JavaScript pauses between steps so the agent never races the page. It exposes a REST/MCP API for local use and supports tab/navigation, input, screenshots with element markup, a virtual cursor, dialogs, file pickers, downloads, execution control, and session recording for training.

Physicist Astrid Eichhorn argues for asymptotic safety: quantum gravity remains well-behaved at the Planck scale if there is a finite, nontrivial fixed point, with scale symmetry linking Planck-scale physics to the macroscopic world. Her work, and collaborators', suggests matter and gravity converge to this fixed point even with known fields, implying a fractal-like space-time where laws stop changing at small scales. If true, it can predict particle masses (Higgs, top, neutrinos) and constrain dark-matter candidates, while possibly compatibile with other quantum-gravity ideas. Experiments test these implications.

Wiz officially joins Google, uniting Wiz’s cloud security with Google’s scale to accelerate security in the AI era. Wiz remains multi-cloud (AWS, Azure, GCP, OCI) and will deepen integration with Google Cloud, Mandiant threat intel, and the Google Unified Security Platform. Over the past year Wiz expanded its AI Security Platform—covering AI usage visibility, AI-native risk prevention, and runtime protection—and launched Wiz Exposure Management, AI Security Agents, and WizOS base images. Security research highlighted systemic risks (Moltbook, CodeBreach, RediShell, NVIDIAScape) and supply-chain attacks. The company plans to leverage Gemini and continue innovating, with demos available.

Bloomberg's Temporal piece centers on a nine-year effort to replace Date with Temporal in JavaScript. Born from early pain points—mutability, inconsistent parsing, and calendar/time-zone handling—the proposal evolved through TC39 with Bloomberg and Igalia leadership. It culminated in Stage 4 approval and broad shipping (Firefox, Chrome, Edge, TypeScript, and more). Temporal introduces a top-level Temporal namespace with ZonedDateTime, Instant, a family of Plain* types, calendars, and Duration, plus a shared temporal_rs library to unify engines. Future work includes integrating with date pickers and DOM timestamps.

Learning requires falling, not just skirting danger. After taking up inline skating, the author found faster progress by embracing falls safely (with gear and technique). Adults’ fear of pain makes them hesitate, slowing growth. The principle applies to music and writing: letting go of perfectionism and trying—even badly—builds skills. Low-stakes risk yields breakthroughs; higher stakes require safer falls. The post endorses practice and Rhythmic Training as a tool, and invites readers to share, subscribe, or hire the author.

Faster asin() Was Hiding In Plain Sight details speeding arcsin in PSRayTracing. After exploring Taylor-series and Padé approaches (with half-angle corrections) and seeing limited gains, the author uncovers a NVIDIA/Cg-inspired fast asin approximation (asin_cg) using a 4th-order Horner polynomial plus a sqrt term. Implemented in C++, it matches std::asin accuracy but runs about 1.5–1.9x faster across tested CPUs (Intel, MSVC, Apple M4). The post emphasizes researching existing fast trig approximations before re-deriving and shares cross-platform benchmarks and lessons learned.

A Cloudflare security block prevents access to ft.com, asking to enable cookies and informing the user they have been blocked by a security service. It notes actions that could trigger the block and suggests contacting the site owner with details and the Cloudflare Ray ID (9dab58c77fb97d12). It also shows the user’s IP and Cloudflare protection.

The article argues that Meta’s smart glasses and other connected devices routinely upload user data to company servers for AI training and advertising. It notes that Windows, Google, and Apple collect telemetry and profiles via terms of service, and cites Yann LeCun’s claim that billions of images are used to train models. It concludes that privacy is not guaranteed: when you use an internet-connected device, your data is controlled by the company, and Meta’s “AI-first” shift intensifies data collection for training and profit.

MPs rejected a Lords amendment to ban under-16s from social media and instead granted ministers sweeping powers to restrict internet access for under-18s without new legislation. The powers could block websites, apps and games, impose digital curfews, or require ID checks/biometric verification, with no proven harm test. Critics warn it cedes control from Parliament and Ofcom to ministers and could enable ideological censorship. The plan threatens adult privacy and data security through age-verification requirements, expands an unregulated age-assurance industry, and calls for regulating providers and pausing deployments until science clarifies benefits/harms.

CodeWall demonstrated an autonomous agent breach of McKinsey’s Lilli AI platform, gaining full production access in ~2 hours. Lilli stores 46.5M chats, 728k files, 57k user accounts, and 384k AI assistants for 70%+ of staff. The test mapped 200+ API endpoints, with 22 unauthenticated; a SQL injection exposed via error messages allowed 15 blind iterations and live data exposure, including prompts and guardrails. Poisoned prompts and data exfiltration were possible. CodeWall offers AI-security testing.
