Ask HN: Who Is Working to Combat AI-Powered Fraud?https://news.ycombinator.com/item?id=46137711There has been a recent explosion in AI-aided scams and fraud. Deepfakes (both video and voice), web scraping, and automated document generation have allowed scammers to target victims with more precision and believability than was ever possible before AI.All of this has always been possible to some degree, but "quantity has a quality all its own" continues to ring true.Public education ("scam awareness") is obviously the most decisive strategy, but is generally left to the underfunded public sector or the PR departments of banks, etc.As for AI-industry regulation, I'm not holding my breath. And besides, with open-source models there will always be products available to bad actors.So is anyone working on anything in the public interest? Any bright ideas?

JWST spots early Milky Way style spiral galaxy Alaknandahttps://www.spacedaily.com/reports/JWST_spots_early_Milky_Way_style_spiral_galaxy_Alaknanda_999.htmlLos Angeles CA (SPX) Dec 03, 2025 Astronomers using NASAs James Webb Space Telescope have identified a massive spiral galaxy that resembles the Milky Way but existed when the Universe was only about 1.5 billion years old. Named Alaknanda, after a Himalayan river paired with the Mandakini which shares its Hindi name with the Milky Way, the system appears as a mature, disk dominated spiral at a time when galaxies were expected to

Show HN: The Almanac – Generate Wikipedia-style biographies of anyonehttps://www.thealmanac.ai/Hi HN,We’ve been building The Almanac, a tool that creates Wikipedia-style articles for any person using their full public online footprint. Unlike Linkedin where people have to maintain their own profile, we automatically crawl the internet for their roles, art, projects, collaborations, publications, media mentions, everything that’s actually documented. You can make a profile for yourself or anyone else by generating it.A few things we focused on:Identity disambiguation: reliably separating people with similar names - this is very tricky and something that GPT/Perplexity gets wrong very oftenFull-stack research agent that crawls, filters, and writes structured articlesDetailed profiles that include timelines, infoboxes, sources, and citationsPublic search plus the ability to generate your own or someone else’s profileYou can try it here: https://thealmanac.aiExample profile: https://www.thealmanac.ai/article/davidliebGenerate a profile (requires login) : https://thealmanac.ai/genera

Show HN: Systemdesigner.net – a free interactive system-design learning platformhttps://www.systemdesigner.net/Hi HN,I built systemdesigner.net, a free platform for learning and practicing system design, ML systems, and GenAI architectures.I originally built it for myself while preparing for system design and ML/AI interviews. I realized my workflow was a mess: reading a blog here, watching a video there, taking notes in Google Docs, and drawing diagrams in entirely different tools. When mentoring engineers I saw the same problem. I wanted a single platform where the material, the practice problems, and the diagramming were part of one continuous loop rather than scattered across the internet.Here’s what it does today:- Guided learning plans you can generate based on what you want to study (distributed systems, ML, LLMs, etc). - Every page has built-in quizzes so you can check understanding immediately. - In-page tools: highlight text, take notes, ask questions, get explanations, or have AI discussions on any concept. - Interactive whiteboards for designing architectures and practicing intervie

Show HN: The $1B problem with business cards nobody's solving properlyhttps://yenhyia.buzzchat.site/88% of business cards are thrown away within a week.The average professional collects 200+ business cards per year. That's 176 contacts lost. If even 10% could've been valuable connections, we're talking about massive opportunity cost.I got obsessed with this problem after watching my own business card graveyard grow. Built a real-time networking platform (Yenhyia) that makes business cards irrelevant.The insight: The problem isn't paper vs digital cards. It's the entire networking workflow.Traditional flow: 1. Arrive at event blind 2. Random encounters 3. Awkward small talk 4. Exchange cards 5. Cards go in pocket/wallet/trash 6. Never follow upNew flow with Yenhyia: 1. See attendees before event (prep who to meet) 2. Match based on goals (mutual opt-in) 3. Chat starts with context (you both chose each other) 4. Meet in person (not random, intentional) 5. Digital card auto-shared in chat thread 6. Contact synced to phone, conversation history preservedThe technical interesting bits:- B

A three-layer memory architecture for long-running agentshttps://news.ycombinator.com/item?id=46097759Anthropic's recent piece on effective harnesses for long-running agents hit close to home. We've been wrestling with the same problems — agents that try to one-shot everything, declare victory prematurely, and leave chaos for the next session to clean up. But we solved some of these problems differently. Here's what's working for us, what isn't yet, and where we respectfully disagree with the proposed solutions.The Memory Problem: Three Layers Beat One Anthropic's solution is a progress.txt file plus git history. It works, but it's flat. We use three layers instead: Layer 1: Model actualization. A semantic memory system that helps the orchestrating agent understand "what are we building and why." This is the soft layer. Layer 2: Think Jira meets Git, but for AI agents. Structured storage of tasks with metadata: blockers, decision paths, dependencies, progress state. The agent doesn't just know what to do next — it understands the logic of how we got here and where we're going. Layer 3:

Show HN: Mitsuki, a Python web framework as fast as Node or Javahttps://github.com/DavidLandup0/mitsukiHey HackerNews! Just wanted to share something slapped together recently, looking for feedback.Context: I worked in both research and enterprise and have built a lot of services in Python and Java, and they converge to using similar patterns, regardless of how different the architectures and domains are (web apps, ML research, distributed systems, etc.)After writing a lot of Python, I was missing a framework that strongly supported some of these patterns formally, and find that this structure lets you make assumptions that can really boost dev experience on long term projects.Microframeworks are great. They let you get started with a single file of a few lines, but (in my opinion) lack the structure you want on long term projects, working with teams, so you end up making that structure yourself anyway. In doing so, you get a small initial boost in productivity, but at the cost of your productivity in the future.Mitsuki tries to both allow you to start quick and easy with a single file

The melting ice raises average global sea level, alters ocean currents and affects temperatures in places far from the poles. But melting ice sheets don't affect sea level and temperatures in the same way everywhere. In a new study, our team of scientists investigated how ice melting in Antarctica affects global climate

Show HN: A Low-Level Bluetooth Hid Remote for Blind Mobile UI Macroinghttps://news.ycombinator.com/item?id=46086952As a former insomniac and engineer, I built this simple, battery-operated HID remote to solve a specific, recurring problem: the unavoidable light exposure and cognitive effort required to skip mobile app ads or sponsor reads while trying to fall asleep. The simple act of fumbling with a bright screen destroys melatonin production, actively sabotaging one's sleep hygiene protocol.The Problem with Standard HID Standard Bluetooth media remotes fail this use case because they rely on the Next Track code, which often skips the entire episode in popular podcast players. They also cannot interact with proprietary UI elements like in-app skip buttons or YouTube's "Skip Ad" overlays. The HID standard and the consumer controls usage table does not include time skipping.The Technical Solution: Pointer Anchoring and UI Macroing This device implements a custom protocol to achieve reliable, precise, and blind UI interaction across both iOS and Android:Low-Level Reports: The firmware leverages basic

Are MAGA and fundamentalist views like antivax a lesion-like brain problem?https://news.ycombinator.com/item?id=46065113Biological and cognitive underpinnings of religious fundamentalism Zhong “we found that participants with dorsolateral prefrontal cortex (dlPFC) lesions have fundamentalist beliefs similar to patients with vmPFC lesions and that the effect of a dlPFC lesion on fundamentalism was significantly mediated by decreased cognitive flexibility and openness. These findings indicate that cognitive flexibility and openness are necessary for flexible and adaptive religious commitment, and that such diversity of religious thought is dependent on dlPFC functionality.” https://pmc.ncbi.nlm.nih.gov/articles/PMC5500821/A neural network for religious fundamentalism derived from patients with brain lesions https://www.pnas.org/doi/10.1073/pnas.2322399121The neural underpinning of religious beliefs: Evidence from brain lesions https://pmc.ncbi.nlm.nih.gov/articles/PMC9583670/

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. We're burning a small nation's power grid because nobody questioned whether copying a sentence needed to ship a document.The semantic lie: Copy and cut were always opposites,

Thoughts of a Neopagan /the Metal Ageshttps://news.ycombinator.com/item?id=46050409Let us imagine walking through a Neolithic village thousands of years ago, surrounded by collectively cultivated fields and domestic animals cared for by the group. There is no struggle for accumulation because this concept is foreign; people work together, share food and resources, economic differences are so subtle as to be almost non-existent, someone may have a few more sheep, but this does not create castes or hereditary privileges; life is organized in an egalitarian way because survival itself depends on cooperation, it is a functioning anarchy, a social eco-balance that honors the cycles of nature. Then something cracks; with the advent of the metal ages, copper, bronze, and finally iron, societies undergo a profound mutation and with this mutation, like poison flowing in a river, the first real social inequalities arise; one wonders why metals? The answer lies not in the material itself, but in the manufacturing process they require. Extracting minerals, smelting, and forging
