Volunteers Find Oddly High Solar Flare Rateshttps://science.nasa.gov/get-involved/citizen-science/volunteers-find-oddly-high-solar-flare-rates/Patches of the Sun’s surface often show strong magnetic fields. These fields can emerge within a matter of hours, and can decay slowly or quickly, sometimes over days, weeks, or even months. Thanks to a new study about these long-lived active regions, we now know much more about the patches where these strong magnetic fields […]Mar 13, 2026 10:07 PM

Looking for Partner to Build Agent Memory (Zig/Erlang)https://news.ycombinator.com/item?id=47356098I’m working on a purpose-built memory platform for autonomous AI agents.Right now, agent memory is stuck between two hohum options: RAG (which loses relational topology) and Graph Databases (which require massive pointer chasing and degrade under heavy recursive reasoning).I'm building an alternative using Vector Symbolic Architecture (Hyperdimensional Computing). By mathematically binding facts, sequences, and trees into fixed-size high-dimensional vectors (D=16,384), we can compress complex graph traversals into O(1) constant-time SIMD operations…and do some quasi brain-like stuff cheaply, that is, without GPUs and LLMs.The design is maturing nicely and strictly bifurcated to respect mechanical sympathy:• The Data Plane (Zig): Pure bare-metal math. 2GB memory-mapped NVMe tiles via io_uring. Facts are superposed into lock-free 8-bit accumulators strictly aligned to 64-byte cache lines. Queries are executed via AVX-512 popcount instructions to calculate Hamming distances at line-rate.

Show HN: I built a Mac app that converts files when you rename themhttps://news.ycombinator.com/item?id=47340433Hi HN,I built Morpholder after repeatedly running into the same annoying workflow on macOS.Every time I needed to convert a file I had to open a converter, upload the file, download it again, and move it back to Finder. It always felt unnecessary when I already knew the format I needed.So I tried a different idea: what if renaming the file actually converted it?Morpholder watches folders and performs the real conversion when the extension changes.For example:favicon.png → favicon.ico photo.heic → photo.jpg video.mov → video.gif video.mp4 → audio.mp3But it also unlocks some workflows beyond simple conversions:- Append _nobg to an image → background is removed automatically (uses Apple’s subject detection) - Rename an image to .txt → text is extracted from the image using Live Text - Append _min → compress image for the web while preserving quality - Rename an image to .icns → builds a macOS app icon package - Append _pages to a PDF → exports each page as high-resolution imagesThe app ruMar 11, 2026 7:54 PM

Show HN: Reviewd – A free, local alternative to Claude Code Review(no API costs)https://github.com/simion/reviewdAnthropic just launched their official Claude Code Review tool, pricing it at $15–$25 per PR. If your team is shipping 10+ PRs a day, that model scales terribly.Even before their launch, I was running a custom local Claude agent for my team to review PRs. The feedback was great and it caught real bugs, but the workflow was a massive time sink. I was manually invoking "claude --agent .. branch_name", grab the output, filter it and post the relevant comments.So I built reviewd to automate the local execution: https://github.com/simion/reviewdIt is a Python-based background daemon that runs on your machine or a VPS.How it works: 1. It polls GitHub/BitBucket for open PRs. 2. Creates a near-instant git worktree (no re-cloning). 3. Optionally runs your actual local test/lint commands (the AI gets the stdout/stderr). 4. Pipes the context into the Claude, Gemini, or Codex CLI you already have installed. 5. Parses the JSON output and automatically posts structured inline and summary comments toMar 11, 2026 4:43 PM

COPV Damage Tolerance Life Demonstration Guidelineshttps://www.nasa.gov/centers-and-facilities/nesc/copv-damage-tolerance-life-demonstration-guidelines/The NESC has invested significant time and resources to better understand composite overwrapped pressure vessels (COPV) performance and more importantly, how these complex, high-pressure storage systems can fail. These vessels, which store high pressure propulsion and life-support system fluids on launch vehicles and spacecraft, are ubiquitous at NASA, and failures have the potential to be catastrophic.

Show HN: Movie site built on a game enginehttps://movie-chain.com/I'm an ex-gamedev (Guitar Hero) who built a movie website that looks like a Trello board. Each column can contain a different movie or cast member. Load pre-made boards or create your own by dragging and dropping between the columns. You can share boards with others.For example, start with Quentin Tarantino’s movies in Column 1, put the cast of Once Upon a Time in Hollywood in Column 2, then put Brad Pitt’s entire filmography in Column 3. Keep going as long as you want, building a "chain" ala Six Degrees of Kevin Bacon.I was frustrated that all popular movie websites are page-oriented: one HTML page per movie or person. I asked myself what a movie site designed in 2026 would look like, in an era when full-screen canvas sites like Miro are common. And then asked what if the site was built on a game engine? I used PixiJS.I ingested TMDB movie data into my own SQLite database head of time, so there are no external API calls at runtime. This was necessary because opening a board with 100'sMar 8, 2026 3:17 PM
