White dwarf magnetic field study reveals inner accretion dynamicshttps://www.spacedaily.com/reports/White_dwarf_magnetic_field_study_reveals_inner_accretion_dynamics_999.htmlCambridge, MA (SPX) Nov 21, 2025 Some 200 light years from Earth, the core of a dead star is circling a larger star in a macabre cosmic dance. The dead star is a type of white dwarf that exerts a powerful magnetic field as it pulls material from the larger star into a swirling, accreting disk. The spiraling pair is what's known as an "intermediate polar" - a type of star system that gives off a complex pattern of intense radiatNov 26, 2025 9:07 AM

Show HN: I built directory of fashion brands because I didn't know how to dresshttps://brandlist.it.comHi HN guys! I hope you have a happy day.A year ago, I was terrible at grooming and styling myself. To be honest, it severely affected my self-esteem and made me hesitant to even go outside.I didn't want to be a supermodel or hot—I just wanted to look like a normal person. But when I tried to find clothes, I hit a wall. I didn't know which brands were good, what style I liked, or where to start. I wasted hours just looking for a simple shirt.So, I decided to solve this problem the way I know how: by building a tool.BrandList is a directory of fashion brands categorized by specific styles (like "Classic", "Minimal", "Streetwear"). The goal is to help people find brands that fit their vibe without knowing the specific brand names beforehand.Key Features:Curated by Style: You don't search by name; you browse by "look."No Login Required: You can add/suggest brands without signing up (I hate friction).It is currently an MVP. I would love your feedback on the UX and the categorization. If youNov 26, 2025 8:17 AM

ClipE96: We Left the Clipboard Unguarded for 40 Yearshttps://news.ycombinator.com/item?id=46051434In 1984, Apple shipped copy and paste. It was a miracle of usability—and architecturally broken from day one.Press Ctrl+C and the entire payload—bytes, formatting, metadata, embedded objects—dumps into a system buffer that any application can read. No auth. No logging. No revocation.The clipboard is a broadcast channel disguised as a convenience.The catastrophe: The clipboard is now the #1 data exfiltration vector in enterprise. 77% of knowledge workers paste corporate data into AI tools. Every paste bypasses your CASB, EDR, SIEM, and DLP. Your security stack guards the front door while users walk data out the side.The waste: 40 billion copy operations/day × ~100KB average = 4 exabytes of daily churn. RAM pressure, cloud sync, VM duplication—all unnecessary. Annualized: 83B kWh, 33M tons CO₂, $10B in energy costs.

Ask HN: Have you used an LLM for grief support?https://news.ycombinator.com/item?id=46047833My wife of 14 years recently told me she wants to end our marriage. One of the main reasons is that she has felt overwhelmed in a long‑term caregiving role: I have generalized anxiety disorder, and although I’ve been in counseling for years (EMDR, family‑systems work), take an SSRI, meditate daily, and avoid alcohol/drugs, I still sometimes panic when I think I might upset someone. I’m actively working on it, but this news has been devastating.Emotionally, it feels similar to grief after a major loss. I've been crying a lot, have little appetite, and feel physically sick I'm in touch with friends and my therapist, but I've also been turning to LLMs for supplemental support, and suprisingly, it has been very helpful. It's strange to feel comforted by a machine, but it has helped me emotionally.I'm curious how others see this.Have you used an LLM for grief processing or therapy? What was helpful, what wasn't, and what risks are there?I'm not treating it as a replacement for friends or a Nov 25, 2025 4:57 PM

Launch HN: Onyx (YC W24) – Open-source chat UIhttps://news.ycombinator.com/item?id=46045987Hey HN, Chris and Yuhong here from Onyx (https://github.com/onyx-dot-app/onyx). We’re building an open-source chat that works with any LLM (proprietary + open weight) and gives these LLMs the tools they need to be useful (RAG, web search, MCP, deep research, memory, etc.).Demo: https://youtu.be/2g4BxTZ9ztgTwo years ago, Yuhong and I had the same recurring problem. We were on growing teams and it was ridiculously difficult to find the right information across our docs, Slack, meeting notes, etc. Existing solutions required sending out our company's data, lacked customization, and frankly didn't work well. So, we started Danswer, an open-source enterprise search project built to be self-hosted and easily customized.As the project grew, we started seeing an interesting trend—even though we were explicitly a search app, people wanted to use Danswer just to chat with LLMs. We’d hear, “the connectors, indexing, and search are great, but I’m going to start by connecting GPT-4o, Claude Sonnet Nov 25, 2025 2:20 PM

Show HN: Open-Source Visual Wiki Your Coding Agent Writes for Youhttps://www.npmjs.com/package/daviaHi HN,We’re Ruben, Afnan, and Theo. A couple of days ago we released the early repo for Davia and were surprised by how much feedback came in right away. We decided to turn it into a full open-source package you can run locally.Davia is designed for coding agents to generate an editable internal wiki for your project. It focuses on producing high-level internal documentation: the kind you often need to share with non-technical teammates or engineers onboarding onto a codebase. Writing this kind of documentation takes forever, diagrams are often missing, and most tools don’t let you edit everything locally or integrate smoothly with your workflow.Davia is fully open source. It produces an editable workspace: – Text lives in a Notion-like editor – Diagrams live on editable whiteboards – Everything runs locally and can be modified either in your IDE or in the workspaceOne thing people found especially interesting is that you can delegate the documentation to your IDE’s AI agent.
