AI Summarized Hacker News
Front-page articles summarized hourly.
Amazon's Rufus shows embeddable AI agents can generate billions, but most sites can't match that scale. Google's WebMCP would route interactions via Chrome, sidelining your site. The solution: own your agent with Rover—DOM-native, deployed in one script, understands your page and acts for users (clicks, forms, tours) without exposing APIs or RAG pipelines. Rover outperforms screenshot- or API-based approaches (81.39% WebBench, 21k+ users, 1.5M+ workflows). Potential gains: higher conversions, better onboarding, lower cart abandonment. Live now; launching Feb 25, 2026; one-line deployment.

How to isolate LLM agents by running them in Libvirt/KVM-based VMs on Linux, reducing security risks from broad permissions ('yolo mode') and enabling persistent, mobile access. The guide covers: why Libvirt/ Virsh; installing QEMU/KVM and libvirt; downloading and resizing an Ubuntu cloud image; creating a VM with cloud-init; accessing via SSH or Tailscale; inside the VM: basic tooling, tmux persistence, bash utilities; installing Claude Code, Gemini CLI, Codex; exposing services with tunnels; VM management with virsh (start, stop, snapshot, clone); cloud-init customization, snapshots, cloning, networking; quick-reference commands; and a brief Libvirt vs Lima comparison.

Bubble Sort on a Turing Machine: sorts tape input using bubble sort, provided as YAML compatible with turingmachine.io. Two variants: decimal (bubble_sort.yaml) using digits 1–7 (25 states) and unary (bubble_sort_unary.yaml) with 0-delimited unary encoding (~30 states). Includes a Python emulator (emulator.py), a generator, and a ~135-test suite. Paste YAML into turingmachine.io to watch the sort; e.g., 327154 → 123457. MIT license.

IBM says it will triple Gen Z entry-level hiring, reshaping roles for AI fluency. Software engineers will do less routine coding and more customer interaction; HR will handle more via chatbots. IBM argues investing in junior talent creates durable skills and avoids future leadership shortages, even as AI pressures rise. CEO Arvind Krishna had vowed to hire more graduates, though IBM later cut thousands of workers—a net near-flat U.S. headcount. Dropbox and Cognizant also embrace Gen Z and AI skills. AI literacy is now the fastest-growing U.S. skill.

Full-body MRIs promise a health baseline but many experts question their value for asymptomatic people. They can identify incidental findings and some cancers, but they risk overdiagnosis, unnecessary biopsies, emotional and financial costs, and are not insurance-covered. In Prenuvo/Function’s Polaris study of 1,011 people, 41 had biopsies and more than half were diagnosed with cancer; 68% of those cancers had not been targeted by screening, and 64% were localized when detected. Across populations, confirmed cancer detection is around 1.6% with notable false positives. Critics urge ‘context’ and caution; cheaper, throughput-focused baselines may evolve.

Argues OpenAI should build an OpenAI Slack, combining chat, coding, and enterprise collaboration into a single, multiagent UX. Slack’s faults (costs, outages, API friction, noisy notifications) and its broad tech dominance make it a prime target. By layering a company’s social and work graphs onto ChatGPT, OpenAI could deliver real-time, multiplayer collaboration and powerful coding agents, creating a sticky, scalable workspace that deters churn and solidifies OpenAI’s enterprise moat.

Dune2JS is an HTML5/JavaScript reimplementation of Dune II: The Building of a Dynasty by Oliver Klemenz (oklemenz). Hosted on GitHub (oklemenz/Dune2JS) with an online Play version at dune2js.com and a GitHub Pages variant (oklemenz.github.io/Dune2). It supports browser and mobile play, fullscreen/add-to-home-screen, and local development via Node.js (clone, npm install, npm start) served at localhost:8080. Project uses JavaScript, CSS, and HTML, credits contributors including Tiago Filipe Silva.

Dynamic visualization of the Euler gamma function Γ(x + i c) in the complex plane, showing real (blue) and imaginary (purple) parts as c sweeps from 0 (real Γ) through positive and negative values. The imaginary part mirrors across the x-axis on negative sweeps; when c becomes large, it resets and the sweep repeats. Based on vanilla_gamma(), derived from vanilla_zeta() from zeta-calculator.com; CC0 licensed, you may copy/paste. The tool aims to illuminate the gamma function's graphical behavior. Controls: X to resume, ζ(s) to visit zeta-calculator.com.

Directory index for NTDesignWorkbook containing dozens of DOC and PDF documents (e.g., alerts, io, proc, vm, vmdesign, namepipe, os2, etc.). Each entry shows file size (roughly 31KB–348KB) and the date 2022-May-27. The listing includes both .doc and .pdf versions for many topics; overall a catalog rather than content.

Nicole Express rants about rampant online misinformation, using the 1994 Phantasy Star Fukkokuban as a case study. She explains the game is a Master System title repackaged for Genesis, discusses how unreliable search results and LLMs can fill gaps with plausible but inaccurate details, and critiques SEO-driven blogs like Press Start Gaming and monetized content. The post reflects on trusting online sources, the AI era's hallucinations, and the need to rely on established reputations over click-generated internet noise.

Simon Willison’s blog discusses Google’s Gemini 3 Deep Think and its mission to push AI across science and engineering, then centers on his SVG-generation experiments of a pelican riding a bicycle. After a basic SVG, he attempts a more challenging California brown pelican version with detailed specs (spokes, frame, pouch, feathers, pedaling, full plumage) and shares the result, plus related posts and tags.

Fu Yong Quah explains porting Jane Street's Hardcaml_step_testbench from monadic Async-style code to OCaml 5 algebraic effects using Handled_effect. He argues monads make code harder to read and constrain features like unboxed types; algebraic effects let computations suspend and be resumed via handlers, with a local mode to ensure type safety. The post walks simple examples (Plus_one/Subtract_one) and then a hardware-simulation use: modeling a testbench with Step synchronization across multiple concurrent computations, replacing closures and complex run loops with effect handlers and continuations. It includes toy implementations showing how to express run_computations and step.

Dr. Mehmet Oz proposes AI avatars to expand rural health care as part of a $50 billion plan, including digital avatars for basic interviews, remote diagnostics with robots, and drone deliveries; he even floated AI-guided obstetric care. CMS says AI tools should extend—not replace—licensed clinicians and require evidence-based use under oversight. Critics warn AI could erode human connection, risk testing underserved rural populations, and worsen gaps where broadband is unreliable. Some tech leaders say AI could cut administrative burdens and widen access. No full implementation plan has been released.

A lightweight, header-only C library (vdb) for storing and querying high-dimensional vector embeddings. Implemented as a single header (vdb.h) with optional multithreading, multiple metrics (cosine, Euclidean, dot product), and persistence via save/load. Supports custom allocators and has no external dependencies except pthreads. Includes a C API for creating/destroying databases, adding/removing vectors, k-NN search, and retrieving results, plus Python bindings (vdb.py). Licensed Apache-2.0.

News publishers are restricting Internet Archive access amid AI scraping concerns. The Guardian and The New York Times are hard-blocking IA crawlers and Wayback access to curb AI training data leakage. The Financial Times blocks IA scraping of paywalled content. Publishers worry IA provides easy access to content for AI models; IA founder Brewster Kahle warns restricting libraries harms public access. The discussion highlights bots such as archive.org_bot and ia_archiver; a Nieman Lab survey found 241 sites disallow at least one IA bot, with Gannett outlets often blocking two. Le Monde group blocks multiple IA crawlers as well.
