Young ‘Sun’ Caught Blowing Bubbles by NASA’s Chandrahttps://www.nasa.gov/missions/chandra/young-sun-caught-blowing-bubbles-by-nasas-chandra/For the first time, a much younger version of the Sun has been caught red-handed blowing bubbles in the galaxy, by astronomers using NASA’s Chandra X-ray Observatory. The bubble – called an “astrosphere” – completely surrounds the juvenile star. Winds from the star’s surface are blowing up the bubble and filling it with hot gas […]Feb 23, 2026 8:07 PM

Show HN: AIOffice – Terminal tabs don't scale past 3 AI agents, so I built thishttps://github.com/ChristianFJung/AIOfficeI've been running multiple AI coding agents in parallel through Claude Code and Copilot CLI and imo once you get past 3 concurrent tasks, terminal tabs become unmanageable.So I built AIOffice — a pixel-art virtual office where each agent sits at a desk. You walk around as the boss, assign work, and see everyone's status at a glance. When you need to interact with an agent, you walk over and chat.How it works: - Each agent is a real CLI process running in a PTY on your machine - Server watches JSONL output, bridges messages over WebSocket - Phaser renders it all as a pixel-art office with spatial awareness - You chat with agents using their native CLI interfacesThe spatial metaphor turns out to be surprisingly useful — you naturally remember "Bob is at the desk by the window working on the API" instead of "which tab was that Claude instance in?"Runs on your machine and uses your CLI tools. Built with TypeScript, Phaser 3, node-pty, and WebSockets.Repo: https://github.com/ChristianFJung/Feb 23, 2026 7:52 PM

Show HN: BasaltSurge – Web3 POS checkout and AI-agent commerce APIhttps://surge.basalthq.comI’m Michael, and my team at BasaltHQ has been building BasaltSurge. We originally started this under the name PortalPay, but recently rebranded as the scope expanded. It’s a payment engine designed to bypass legacy card rails at the physical point of sale and provide a standardized checkout layer for AI agents.Having worked extensively on data and payment solutions for high-friction retail environments where traditional processors take massive cuts or deny service entirely, we wanted to build something genuinely permissionless.Here is a breakdown of what we built:QR-Based POS Checkout: Merchants print a QR code on their standard POS receipt. Customers scan it to access a white-labeled, web3-native checkout on their phone. It accepts USDC, USDT, cbBTC, and ETH on the Base network. We utilize Account Abstraction (AA) for gas sponsorship so the end-user UX isn't bottlenecked by network fee friction.Built for the Machine Economy: We unified Google's Universal Commerce Protocol (UCP) with tFeb 23, 2026 2:22 PM

For those unfamiliar, OSWorld tests whether AI agents can actually use a computer the way a human does navigating real desktop environments, clicking through UIs, filling out forms, managing files across apps.We're building an agent execution platform for computer-use AI. Think of it like Vercel but for AI agents that operate full desktop environments. You give Coasty a task, and it spins up a sandboxed environment where an agent can see the screen, move the mouse, type, and complete end-to-end workflows things like filing expenses, canceling subscriptions, filling out insurance forms, or navigating legacy enterprise software. Why this mattersMost "AI automation" today is really just API glue between apps that have APIs. But the vast majority of business workflows still live Feb 23, 2026 3:13 AM

Show HN: I'm building a pure-Rust reimplementation of rsync (Protocol 32)https://github.com/oferchen/rsyncYears ago, I was tasked with a massive data migration: multiple disks, each containing over 100 million files, with a strict, non-negotiable 24-hour downtime window. Using the standard tools available at the time was a painful experience. The single-threaded file discovery crawled, and memory usage was a constant source of anxiety. I promised myself that one day, I would come back and build a tool that could actually handle that scale natively.What started as a side project has evolved into a full systems-level undertaking. The project is oc-rsync - a complete client, server, and daemon implementation targeting rsync protocol 32, written entirely in pure Rust.I find it incredibly ironic that I am currently shipping a data migration tool while my life is packed in suitcases, as I'm migrating to another country myself. I’ve been pushing git commits multiple times a day between packing boxes.I want to be completely transparent upfront: I am actively working on this, and not everything is Feb 22, 2026 10:51 PM

Show HN: I tracked 800 Reddit URLs on Google – 56% die within 48hhttps://news.ycombinator.com/item?id=47114771I've been experimenting with parasite SEO (ranking Reddit/Quora threads on Google) and noticed my traffic kept dying after a few days.To see if this was systemic, I built a custom scraper and tracked 800 unique UGC URLs across high-competition commercial keywords for a month.The data showed a massive "churn" rate: Out of the 611 threads that dropped out of the Top 10, 56.1% were completely rotated out of the SERPs within 48 hours. Only a tiny fraction survived more than 2 weeks.I published the raw CSV data from the study here if anyone wants to run the URLs through Ahrefs and look for backlink patterns: https://contentrankr.com/ugc-churn-dataStandard rank trackers check weekly, so you don't even realize a thread is dead until days later. I also embedded a tiny free tool on that page using the Serper API where you can paste a Reddit URL and instantly check if Google has dropped it from the index.Curious if anyone else has looked into the "half-life" of Google's new UGC rankings?Feb 22, 2026 9:18 PM

Show HN: OctoFlow v1.0.0 – GPU VM where the GPU runs autonomously, CPU is BIOShttps://news.ycombinator.com/item?id=47113604Three days ago I posted OctoFlow 0.83 here (GPU-native programming language, 2.2 MB binary). The feedback was great. Since then I've pushed v1.0.0 with the thing I've actually been building toward: a GPU Virtual Machine.The idea: the GPU is the computer, the CPU is the BIOS.You boot a VM, program a dispatch chain of kernel instances, submit once with vkQueueSubmit, and everything — layer execution, inter-layer communication, self-regulation, compression, database queries — happens on the GPU without CPU round-trips. The CPU just provides I/O. let vm = vm_boot() let prog = vm_program(vm, kernels, 4) vm_write_register(vm, 0, 0, input) vm_execute(prog) let result = vm_read_register(vm, 3, 30) 4 VM instances, one submit, no CPU involvement between stages.The memory model is 5 SSBOs: Registers (per-VM working memory), Metrics (regulator signals), Globals (shared mutable — KV cache, DB tables), Control (indirect dispatch params), Heap (immutable bulk data — quantized weights).What makes it iFeb 22, 2026 6:55 PM

Show HN: Vexp – graph-RAG context engine, 65-70% fewer tokens for AI agentshttps://news.ycombinator.com/item?id=47113273I've been building vexp for the past months to solve a problem that kept bugging me: AI coding agents waste most of their context window reading code they don't need.The problemWhen you ask Claude Code or Cursor to fix a bug, they typically grep around, cat a bunch of files, and dump thousands of lines into the context. Most of it is irrelevant. You burn tokens, hit context limits, and the agent loses focus on what matters.What vexp doesvexp is a local-first context engine that builds a semantic graph of your codebase (AST + call graph + import graph + change coupling from git history), then uses a hybrid search — keyword matching (FTS5 BM25), TF-IDF cosine similarity, and graph centrality — to return only the code that's actually relevant to the current task.The core idea is Graph-RAG applied to code:Index — tree-sitter parses every file into an AST, extracts symbols (functions, classes, types), builds edges (calls, imports, type references).

Ask HN: How do you test your MyBatis dynamic SQL queries?https://news.ycombinator.com/item?id=47104032(Full Disclosure: I am developing this plugin and drafting this post with the assistance of AI agents. It’s been an eye-opening experiment in how AI can help "scratch an itch" faster than ever.)I’m currently working on a project using MyBatis, and one of the biggest friction points for me is verifying dynamic SQL. Whenever I have a complex query with , , or OGNL expressions, the feedback loop is painfully slow.My current "workflow" (which I find incredibly tedious) is: 1. Copy the raw SQL from the XML mapper. 2. Manually scrub the XML tags like and . 3. Replace all #{param} placeholders with actual values, one by one. (or :param) 4. Finally, paste the cleaned-up SQL into the IDE’s database console to see if it even runs.I was surprised to find that, despite many MyBatis plugins existing, none of them seem to offer a "direct execution with parameters" feature within the IDE. I expected this to be a standard feature by now, but it feels like we’re still stuck with manual labor for query Feb 21, 2026 7:52 PM

A perceptual-first mobile audio DSP experimenthttps://news.ycombinator.com/item?id=47097362Hi HN,I’ve been working on a long-running personal DSP experiment that started from a simple observation: most real-world listening happens on constrained systems — phone speakers, budget earbuds, car audio, Bluetooth, and heavily compressed streams. In that environment, “accurate” or “flat” processing often doesn’t survive contact with reality.Instead of optimizing for frequency response, I tried optimizing for perceptual survival under constraints. The system is built around a few principles:• Virtual pitch / harmonic reconstruction to preserve perceived low-end on small transducers • Targeted removal of low-mid intermodulation zones that create perceived “mud” on cheap hardware • A biologically-informed notch around the ear-canal resonance region to reduce fatigue at higher listening levels • Minimum-phase, high-headroom internal processing to preserve transient coherence • Treating codecs, OS mixers, and streaming artifacts as first-class constraints, not edge casesThe interesting Feb 21, 2026 4:00 AM

Reddit Ads support is leaking PII and actively crossing user sessionshttps://news.ycombinator.com/item?id=47092914I have been dealing with a Reddit Ads account issue over the last week, and it has quickly escalated into a severe privacy and security red flag.

Show HN: AetherCam, a video recorder focusing on audiohttps://aethercamera.proHey everyone,I wanted to share one of my passion projects that I've been working on for the past year. AetherCam is a video recording app that allows you to apply effects to the audio track in real-time. You can boost volume, add reverb, compressor, eq, and delay. Everything on the fly.The idea for AetherCam came to me when I was recording myself playing guitar and thought that the part that I came up with would sound really cool if there was some reverb applied to it. Day after that "revelation", I sat down and started coding the app. I had some prior experience with AVFoundation and Core Audio, as I worked in a startup that dealt with audio for a brief moment, so knew what I needed to get the ball rolling, but still, the effects were one of the toughest part to write.I already have version 1.1 in the works that significantly improves the reverb engine. Would love to know what you think! :)Feb 20, 2026 7:22 PM
