Google's Gemini 4 Argon is a frontier model for long-horizon reasoning, rolling out first to trusted cyber defenders. It sets state-of-the-art scores on DeepSWE v1.1 (77.9%), LVBench (91.7%), and CWE-bench v1 (68%), and can generate up to 1M output tokens. Internally, it optimized quantum subroutines by 40%, freed 300 TiB of memory, and migrated C/C++ code to Rust. Pricing starts at $2 per million input tokens.

A Vulkan reimplementation of Nvidia's DLSS 5 neural rendering network, matching the original bit-for-bit. The same 71-block Swin/ViT network runs FP8 on tensor cores, with all 75 block boundaries byte-identical. A WebGPU port achieves the same exactness in a browser without tensor cores or FP8. You supply the weights. Performance reaches 2.8 ms at 768x768 on an RTX 4070 SUPER.

For over 40 years, the NRO launched suitcase-sized ELINT satellites with code names like URSALA, RAQUEL, and FARRAH. Hitchhiking on larger photo-reconnaissance satellites, they evolved from chasing Soviet radars to delivering tactical electronic intelligence directly to commanders in the field. Newly declassified documents reveal how these tiny spacecraft brought the wizard war of space-based spying to the warfighter.

The Bronze Age collapse around 1200 BC wiped out the Hittites, Mycenaeans, and other great powers, and no comparable empires returned for centuries. Patrick Fitzsimmons argues that the usual suspects—drought, Sea Peoples, famine—don't explain why recovery was so slow. The real culprit: iron. Once ordinary farmers could make weapons locally, the imperial monopoly on violence vanished, and the political equilibrium shifted forever.

New research reveals that traveling waves in the brain are not just simple planar oscillations but include spiral and concentric patterns. These complex waves may help reorganize the brain in real time to meet behavioral demands, potentially playing a central role in memory and cognition. The findings challenge traditional views and open new avenues for understanding how the brain processes information.

Magnitude is an open-source inference engine that compiles and tunes its kernels on your device before a model runs, delivering up to 2x faster performance than llama.cpp—92% faster decode on Apple Silicon and 19% on NVIDIA CUDA. It connects to agents like Pi, OpenCode, and Codex with one click, uses 27% less memory per agent, and works on any Apple Silicon, NVIDIA, or AMD GPU, or just a CPU. Free, private, and Apache 2.0.

During museum visits in Germany and Poland, I kept encountering modular industrial dashboards—the physical control panels that once monitored air traffic, subway trains, and power plants. They light up, count, and even have a day/night switch. I don't know much about them, but they're fascinating design and interaction systems, now largely replaced by software. If you know more, please write.

Halfspace is an experimental IDE for solid modeling with distance fields, built on the Fidget kernel. It lets you incrementally build models, visualize the underlying fields, and export images or triangle meshes. The author, Matt Keeter, has been developing it since April 2025 and emphasizes it is not vibe-coded. The tool is cross-platform, targeting both web and native, and has driven improvements in GPU-accelerated rendering.

In 1981, after being fired from Salomon Brothers, Michael Bloomberg founded Innovative Market Systems to build a terminal that combined real-time data with instant analytics. The first Market Master terminals, delivered to Merrill Lynch in 1982, gave traders an unprecedented window on global markets. The terminal evolved from a closed network with a custom keyboard to a subscription-based service costing over $32,000 a year, becoming an icon of financial power.

Netlify rebuilt its Edge Functions infrastructure, replacing a hosted V8 isolate service with Firecracker MicroVMs running inside its own edge network. Median warm invocation latency dropped from 25–40ms to 5–6ms, p99 improved by 47.4%, and availability reached 99.998%. The migration, done with Unikraft, adds stronger isolation, scales to zero, and keeps the same pricing and developer experience.

On September 30, 2026, EDG's C++ front-end source code becomes public, with The C++ Alliance as its nonprofit home. The same engine and standards continue under a new steward, funded by tax-deductible contributions. Three development tracks—community contributions, ongoing maintenance, and collectively funded features—ensure one codebase for everyone, with no early access. John Spicer chairs the Fiscal Sponsorship Committee overseeing the process.

Ledge is an open-source Markdown notebook that executes shell commands, code, SQL, and AI prompts directly in your notes. Each note gets its own persistent shell, so variables and directories carry over between runs. Run blocks locally, on a remote server over SSH, or on your phone. Features include profiles for secrets, note locking, git sync, and an MCP server for AI agents. Available for macOS, Linux, Windows, iPhone, and Android. Install with a single curl command.

Chompi Club has released the complete hardware and software source files for the CHOMPI Mk1 sampler as a discontinuation open-source release. The GitHub repository includes firmware for TAPE, TEMPO, and a new WAVE wavetable synth, plus PCB schematics and enclosure files. No further updates or support will be provided, but the community can continue on the Chase Bliss Discord.

Singapore's FirstDate, a pilot dating app for public servants aged 21–35, uses the Gale-Shapley stable marriage algorithm—the 1962 game theory method that won the 2012 Economics Nobel. Users rank preferences, receive one match per cycle with a 72-hour decision window, and contact info is revealed only on mutual yes. Singpass verification ensures authenticity. The app's success metric is deleting its own users.

A farrier in rural France watched a car roll through the next town and soon became a mechanic, keeping his purpose of helping people get around. The author, surrounded by developers anxious about AI, finds comfort in this family story. The real driver, he suggests, was never the code but the joy of making things and solving problems. Be willing to let go of the how to hold on to the why.

Book of Shapes is a curated collection of minimal, generative, and customizable SVG patterns created by Nikolaj Sokolowski. It features over 100 patterns across categories like grid, radial, noise, flow, isometric, organic, distortion, and physics. Each pattern is designed to be easily customized and used in various projects.

A retro website that recreates the dial-up internet experience of 1996, complete with the modem handshake and painfully slow page loads. Hacker News commenters found it fun and nostalgic, though one joked that the pages still load too fast, and another recalled the ripterm client and the Remote Imaging Protocol.

Boris Cherny's claim that Claude Opus used TLA+ to find race conditions has sparked excitement about formal verification. But TLA+ has limits: it can't express reachability properties (like proving a game is winnable), hyperproperties (like energy-saving mode always uses less power), or properties over multiple steps or real time. While hacks like auxiliary variables and self-composition exist, they're messy and don't compose well. TLA+ is great for invariants and liveness, but not a silver bullet for agentic coding.

An American on the MEXT scholarship completed a computer science PhD at Tokyo Institute of Technology while working part-time at Google. He explains why Japan's flexible student visa, three-year graduation clock, and growing AI scene made it attractive, but also warns about name recognition abroad, limited graduate courses, and the isolation of doing a doctorate in a foreign country.

Three people died at Burning Man in 2026, the highest toll in its history. A crude comparison to the U.S. mortality rate predicts about 12 deaths, but after age-standardization the expected number drops to 4.9. Using a Poisson model, observing 3 deaths has a p-value of 0.27—not abnormal. The real anomaly is Burning Man's near-zero death rate over decades, likely due to self-selection of healthy attendees.

Ink & Switch has unveiled PlayBook, a programmable paper notebook that blends physical pages with digital interactivity. A Hacker News commenter calls it one of the coolest demos from the lab in a while, though notes the published live demo omits several demos shown in the talk and leaves unclear how users can build their own, making deeper evaluation difficult.

A set of recommendations for AI labs that produce significant mathematical results. Drawing on over 600 responses from the mathematical community, the document argues that labs must not treat math results as marketing, should release proofs with full attribution and formalization, and must fund human understanding of AI-generated mathematics. It also warns that proprietary models risk creating a two-tier system that alienates mathematicians from their own discipline.

John Coltrane once sketched a diagram for Yusef Lateef: the chromatic scale arranged in circles, with lines tracing harmonic relationships. This post rebuilds that diagram as an interactive widget and decodes its secrets. It reveals how Coltrane changes, tritone substitution, and the 2-5-1 progression all emerge from the circle's symmetric shapes—squares, triangles, and hexagons—that divide the octave into equal parts.

The Great Dirhombicosidodecahedron, known as Miller's Monster, is a uniform star polyhedron with 124 faces, 240 edges, and 60 vertices. It uniquely has eight faces meeting at each vertex and is the only uniform polyhedron with snub faces that are squares. This page documents the construction of a physical model, requiring 1280 external facelets, 42 A4 pages of nets, and an edge length of 21.6 cm.

Functional ultrasound imaging (fUSI) captures rapid movies of brain tissue, tracking blood flow changes with up to 20% signal change—far exceeding fMRI's few-percent BOLD. It offers ten times higher linear resolution, 1000x more voxels, and no magnet. I break down the physics and signal processing, from plane-wave transmission to Power Doppler and clutter filtering, and share Python tutorials to make fUSI accessible beyond Matlab. The modality is far from its ceiling.

The author rants about LinkedIn's performative culture, where every other post is a generic computer vision project, like hand tracking or pothole detection. To prove how trivial these are, he builds his own YOLO-based detector for such posts in 90 minutes, from data collection to training. The real issue, he argues, is that LinkedIn rewards looking interesting over actual skill, so everyone claps and moves on.

A Hacker News thread about SDF, a public access Unix system founded in 1987 that still offers shell accounts to members. Commenters praise its Mastodon and Pixelfed instances, recommend SSHing in for the com chat and bboard discussions, and note a long history of prior HN discussions going back to 2017. One user admits having an SDF login but not knowing what others use it for.

Yantra is a powerful LALR(1) parser generator for C++ that integrates a lexer, parser, and AST builder into one tool. It builds a full AST first, then walks it top-down, enabling parent actions before children. Features include UTF-8 support, multi-mode lexer, and optional amalgamated output. With no dependencies beyond the C++ standard library, it's easy to build and use. Ideal for compiler and language tooling, Yantra offers a fresh alternative to Bison and ANTLR.

GPU text rendering has long relied on texture atlases, SDF, or MSDF—all baked at fixed resolutions that blur or round corners when scaled. Slug, Eric Lengyel's 2017 algorithm, now in the public domain, instead computes per-pixel coverage analytically from glyph outlines in the fragment shader. This article compares the five main approaches and explains why Slug stays sharp at any size, transform, or viewing angle, making it ideal for 3D, AR/VR, and dynamic text.

Pi.dev once proudly declared it would never support MCP, and its team dismissed the protocol on podcasts. Now MCP ships in Pi's core. The shift came after rethinking MCP's evolution and building Codemode, a JavaScript sandbox that orchestrates tool calls. Pi's makers argue MCP should resemble OpenAPI with intelligent tool discovery, and they want to help shape it for small harnesses rather than watch from the sidelines.
