Show HN: A Minimal Monthly Task Planner (printable, offline, no signup)https://printcalendar.top/Hi HN,I built a tiny tool because I couldn’t find a clean, distraction-free monthly planner that:1. shows a clean monthly task view 2. doesn’t require an account 3. doesn’t sync or store anything online 4. works offline 5. is printable 6. and keeps a minimal, distraction-free aestheticSo I made https://printcalendar.top/ — a minimal monthly task planner.It’s intentionally simple. No logins, no integrations, no dashboards. Just a small tool for people who want structure without clutter.Dec 4, 2025 5:29 AM

Show HN: RAG in 3 Lines of Pythonhttps://pypi.org/project/piragi/Got tired of wiring up vector stores, embedding models, and chunking logic every time I needed RAG. So I built piragi. from piragi import Ragi kb = Ragi(\["./docs", "./code/\*\*/\*.py", "https://api.example.com/docs"\]) answer = kb.ask("How do I deploy this?") That's the entire setup. No API keys required - runs on Ollama + sentence-transformers locally.What it does: - All formats - PDF, Word, Excel, Markdown, code, URLs, images, audio - Auto-updates - watches sources, refreshes in background, zero query latency - Citations - every answer includes sources - Advanced retrieval - HyDE, hybrid search (BM25 + vector), cross-encoder reranking - Smart chunking - semantic, contextual, hierarchical strategies - OpenAI compatible - swap in GPT/Claude whenever you want Quick examples: # Filter by metadata answer = kb.filter(file_type="pdf").ask("What's in the contracts?") #Enable advanced retrieval kb = Ragi("./docs", config={ "retrieval": { "use_hyde": True, "use_hybrid_search": True, "use_crosDec 4, 2025 12:03 AM

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/generaDec 2, 2025 9:36 PM

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 intervieDec 2, 2025 4:35 PM

Constant-Current Design for a 100M Outdoor LED Runhttps://news.ycombinator.com/item?id=46118447Last winter, I was asked to design permanent architectural lighting for a 100-meter-long pedestrian pathway in northern Europe. The client wanted uniform, maintenance-free illumination using addressable LEDs—but with one catch: the installation had to survive -30°C winters, summer rain, and run reliably for years without visible voltage drop or color shift.Most off-the-shelf “12V RGB” solutions failed within weeks in testing. Voltage sag over 100m caused the far end to dim by 60%, and thermal drift made white balance inconsistent. So I went back to basics: constant-current control, not constant-voltage.Here’s how I solved it—and why you might want to rethink “just add more power injectors.”Why Constant-Voltage Fails at Scale Standard WS2812B/SK6812 strips are designed for short runs (Dec 2, 2025 7:04 AM

Show HN: ICT – New Information Model for Matter Time Consciousness (Experiment)https://www.academia.edu/s/8924eff666TL;DR: ICT (Information–Consciousness–Time) treats matter as fixed information, consciousness as the rate of informational change, and time as the structuring of this change. The model unexpectedly drew interest from researchers in information physics (feedback below) and includes three concrete falsifiable experiments.1. Core IdeaThree base relations:1. Matter = fixed information M = I_fixed2. Consciousness = rate of informational change C ∝ dI/dT3. Reality = interaction of stable and flowing information R = f(I_fixed, dI/dT)This connects to Landauer’s limit, free-energy principle, Bekenstein bounds, and integrated-information concepts, but treats information itself as the fundamental physical substrate.2. Time as informational processIn ICT, time is:> “The transition of potential information into structured experience.”This links phenomenological time, physical time, and informational/computational time. Consciousness “shapes” this transition → generating an effective local arrow of Dec 1, 2025 9:11 PM

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:Nov 30, 2025 4:05 PM

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 basicNov 29, 2025 12:10 PM
