Story cards stay below the sticky dock while audio, chapters, date, and brief navigation remain accessible.
Image-blaster is a Claude skillset that orchestrates multiple AI models to transform a single photo into a full 3D environment in under five minutes. It chains World Labs' marble-1.1 for Gaussian splat scenery, Hunyuan 3D via FAL for textured meshes, and ElevenLabs for ambient sound effects. Output plugs directly into Unity, Unreal, Blender, or Three.js with adjustable polygon counts up to 1.5 million faces.
An in-browser PPO reinforcement learning demo that trains a neural network to play Snake entirely on your GPU via WebGPU. Built on tinygrad's TinyJit-to-WebGPU pipeline, it lets you watch training metrics in real time, run multi-seed experiments, and compare hyperparameter sweeps. It's a slick demonstration of how ML training is being democratized right inside the browser.
Borealis is a pure-OCaml CCSDS protocol stack that launched into low Earth orbit on April 23, 2026, aboard DPhi Space's ClusterGate-2 satellite. It handles end-to-end encrypted command-and-control with post-quantum key rotation (ML-DSA-65), eliminating the entire class of memory corruption CVEs that plague C/C++ flight software. Using Jane Street's OxCaml branch, they cut p99.9 latency from 29ns to 9ns per packet with zero GC pressure.
A sharp-eyed developer discovered that Bun's Rust rewrite contains undefined behavior in code marked as safe — specifically, lifetime erasure in PathString that enables use-after-free via dangling pointers. The issue blew up with 180 upvotes and 62 laugh reactions on GitHub. A collaborator has since submitted a PR marking affected functions as unsafe and auditing roughly 70 call sites.
Google's Project Zero chained two vulnerabilities for a full zero-click exploit on the Pixel 10: a Dolby audio CVE for remote entry and a VPU driver bug that lets userspace map arbitrary physical memory into userland. Since the kernel sits at a predictable physical address on Pixel, no ASLR bypass was needed. The VPU bug was patched 71 days after the initial report.
The Department of Justice subpoenaed Apple and Google for download and account data on over 100,000 users of EZ Lynk's Auto Agent app, which pairs with an OBD dongle for vehicle diagnostics and modifications. The DOJ alleges the app enables Clean Air Act violations by bypassing emissions controls. The EFF has flagged the dragnet's chilling effect on users who downloaded the app for legitimate diagnostic purposes, and both Apple and Google are reportedly preparing legal challenges.
The venerable digital library now hosts over 75,000 free ebooks and has added nearly 5,000 computer-generated audiobook titles through a collaboration with Microsoft and MIT. No registration, no proprietary apps — everything works in standard browsers and ebook readers. Classics like Frankenstein and Moby Dick remain the top downloads, and the volunteer-driven Distributed Proofreaders pipeline keeps new titles flowing.
Zenith is a browser-based planetarium that shows a hyper-zoomed-in real-time view of the sky above you at roughly 180x magnification — stars visibly drift across the screen in about 30 seconds as Earth rotates. It pulls imagery from the Pan-STARRS telescope survey and overlays object names from the SIMBAD database, all while keeping your location data strictly on-device. Built entirely in client-side JavaScript using Leaflet.js.
A fully functional scientific calculator built on a custom 4-bit (nibble-oriented) soft CPU written in SystemVerilog, naturally suited for BCD arithmetic where each decimal digit fits in one nibble. It targets Altera Cyclone II FPGAs and includes web-based simulators for testing in the browser. The project spans 983 commits and includes a Python microcode assembler and Qt 6.9+ desktop interface.
A nostalgia-drenched web app that wraps all of Wikipedia in a fully functional Windows XP desktop interface — categories become folders, articles become documents, and you can right-click Wikimedia Commons images to set them as your wallpaper. It also includes a Geofile Explorer for geographic browsing with drag-and-drop image uploads. The top-voted HN story today at 407 points.
