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.

Help Galaxy Zoo: Tidal Tales Open Cosmic Storybookhttps://science.nasa.gov/get-involved/citizen-science/help-galaxy-zoo-tidal-tales-open-cosmic-storybook/Galaxies carry the imprints of past encounters. When they pass near one another or collide, gravity pulls their stars into long tails, thin streams, and faint shells – features that preserve the history of these dramatic events. Thanks to deep, high-resolution images from the Euclid space telescope, an ESA (European Space Agency) mission with critical contributions from NASA, we can now see these delicate structures more clearly than ever before in unprecedented numbers.Mar 12, 2026 3:41 PM

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

Apollo Cosplay on a 21st-Century Clock - Why Artemis Keeps Slipping Toward 2029 - Part 3https://www.spacedaily.com/reports/Apollo_Cosplay_on_a_21st_Century_Clock_Why_Artemis_Keeps_Slipping_Toward_2029_Part_3_999.htmlLos Angeles CA (SPX) Mar 09, 2026 NASA's latest reboot of the Artemis Moon program comes with familiar language: 'back to basics,' 'muscle memory,' 'step-by-step,' and an explicit nod to the Mercury-Gemini-Apollo playbook. The agency wants to fly more often, change hardware less, and build up capability incrementally, just like the 1960s. The problem is that Artemis is trying to cosplay Apollo in a world with very different politics, partners and rivals - and the gaps are showing.Mar 9, 2026 5:07 AM

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.

Show HN: Trawl – LLM-powered web scraper that calls the AI once - runs pure Gohttps://news.ycombinator.com/item?id=47297522Every scraper I've written has the same failure mode: it works for three months, a site redesigns, and my CSS selectors silently return empty strings. The data is still right there on the page — a human can find it instantly — but the scraper is blind.Trawl fixes this by splitting the problem. You describe what you want: trawl "https://books.toscrape.com" --fields "title, price, rating, in_stock" The LLM (Claude) looks at one sample item and derives a full extraction strategy — CSS selectors, attribute mappings, type coercion, fallback selectors. That strategy gets cached. Every subsequent page with the same structure is extracted with pure Go + goquery. No API calls, no token cost, full concurrency.The key insight: LLMs are good at understanding HTML structure, but you don't need them to extract 10,000 rows. Use AI for intelligence, Go for throughput.When a site redesigns, the structural fingerprint changes, the cache misses, and trawl re-derives automatically.You can preview exactly Mar 8, 2026 2:18 PM

Show HN: PolyClaude – Using math to pay less for Claude Codehttps://github.com/ArmanJR/PolyClaudeHi HN!I built this tool specifically for Claude Code users who hit the 5-hour rate limit wall mid-flow. There's no official plan between Pro ($20/mo) and Max ($100/mo). it's a fixed gap with nothing in between.The workaround most people do manually: running multiple Pro accounts and switching when one is limited. This actually works, but naive rotation wastes a lot of capacity. When you activate an account turns out to matter as much as which one you use. A single throwaway prompt sent a few hours before your coding session can unlock an extra full cycle.PolyClaude automates this. You tell it your accounts, your typical coding hours, and how long you usually take to hit the limit. It uses combinatorial optimization to compute the exact pre-activation schedule, then installs cron jobs to fire those prompts automatically. When you sit down to work, your accounts are already aligned.It's free and open source. Install is one curl command, then an interactive setup wizard handles the rest.RMar 7, 2026 10:24 PM
