Show HN: Astroworld – A universal N-body gravity engine in Python I’ve been working on a modular N-body simulator in Python called Astroworld. It started as a Solar System visualizer, but I recently refactored it into a general-purpose engine that decouples physical laws from planetary data.Technical Highlights:Symplectic Integration: Uses a Velocity Verlet integrator to maintain long-term energy conservation ($\Delta E/E \approx 10^{-8}$ in stable systems).Agnostic Architecture: It can ingest any system via orbital elements (Keplerian) or state vectors. I've used it to validate the stability of ultra-compact systems like TRAPPIST-1 and long-period perturbations like the Planet 9 hypothesis.Validation: Includes 90+ physical tests, including Mercury’s relativistic precession using Schwarzschild metric corrections.The Planet 9 Experiment:I ran a 10k-year simulation to track the differential signal in the argument of perihelion ($\omega$) for TNOs like Sedna. The result ($\approx 0.00...

Show HN: PostForge – A PostScript interpreter written in Python Hi HN, I built a PostScript interpreter from scratch in Python. PostForge implements the full PostScript Level 2 specification — operators, graphics model, font system, save/restore VM, the works. It reads .ps and .eps files and outputs PNG, PDF, SVG, or renders to an interactive Qt window. Why build this? GhostScript is the only real game in town for PostScript interpretation, and it's a 35-year-old C codebase. I wanted something where you could actually read the code, step through execution, and understand what's happening. PostForge is modular and approachable — each operator category lives in its own file, the type system is clean, and there's an interactive prompt where you can poke at the interpreter state. Some technical highlights: - Full Level 2 compliance with selected Level 3 features - PDF output with Type 1 font reconstruction/subsetting and TrueType/CID embedding - ICC color management (sRGB, CMYK...

Show HN: Trust Protocols for Anthropic/OpenAI/Gemini Much of my work right now involves complex, long-running, multi-agentic teams of agents. I kept running into the same problem: “How do I keep these guys in line?” Rules weren’t cutting it, and we needed a scalable, agentic-native STANDARD I could count on. There wasn’t one. So I built one. Here are two open-source protocols that extend A2A, granting AI agents behavioral contracts and runtime integrity monitoring: - Agent Alignment Protocol (AAP): What an agent can do / has done. - Agent Integrity Protocol (AIP): What an agent is thinking about doing / is allowed to do. The problem: AI agents make autonomous decisions but have no standard way to declare what they're allowed to do, prove they're doing it, or detect when they've drifted. Observability tools tell you what happened. These protocols tell you whether what happened was okay. Here's a concrete example. Say you have an agent who handles customer support tickets...

Show HN: LockFS LockFS is a small open-source Java tool that encrypts files individually instead of bundling everything into a single container. Many vault systems rely on large encrypted blobs or container files. They can become complex to handle as they grow and complicate backups across mixed storage sizes. LockFS takes a file-level approach: - Each file is encrypted independently - No monolithic container growth - Files can be added, moved, or removed without rewriting a large archive Contributions and feedback are welcome. https://ift.tt/TM6Bs98 February 18, 2026 at 11:42PM

Show HN: I wrote a technical history book on Lisp The book page links to a blog post that explains how I got about it (and has a link to sample content), but the TL&DR is that I could not find a lot of books that were on "our" history _and_ were larded with technical details. So I set about writing one, and some five years later I'm happy to share the result. I think it's one of the few "computer history" books that has tons of code, but correct me if I'm wrong (I wrote this both to tell a story and to learn :-)). My favorite languages are Smalltalk and Lisp, but as an Emacs user, I've been using the latter for much longer and for my current projects, Common Lisp is a better fit, so I call myself "a Lisp-er" these days. If people like what I did, I do have plans to write some more (but probably only after I retire, writing next to a full-time job is heard). Maybe on Smalltalk, maybe on computer networks - two topics close to my heart. A...

Show HN: AsdPrompt – Vimium-style keyboard navigation for AI chat responses I use Claude throughout the day and kept getting annoyed by the same thing: selecting text from responses with the mouse. Overshoot, re-select, copy, click input, paste. Especially bad in long conversations where you want to reference something from 30 turns ago. asdPrompt is a Chrome extension that adds hint-based navigation (like Vimium) to AI chat interfaces. Cmd+Shift+S activates the overlay, hint labels appear next to every text block. Type a letter to select a block, then keep typing to drill down: block → sentence → word. Enter copies, or you can press an action key (e, d, x) to inject a follow-up prompt ("elaborate on [selection]") directly into the chat input. Works on claude.ai, chatgpt.com, and gemini.google.com. Adapts to light/dark themes. Free. Built the initial MVP in 2 days using Claude Code — the adapter architecture, NLP segmentation pipeline, and Playwright test harness would have t...

Show HN: An open-source extension to chat with your bookmarks using local LLMs I read a lot online and constantly bookmark articles, docs, and resources… then forget why I saved them. Also was very bored on Valentines, so I built a browser extension that lets you chat with your bookmarks directly, using local-first AI (WebLLM running entirely in the browser). The extension downloads and indexes your bookmarked pages, stores them locally, and lets you ask questions. No server, no cloud processing, everything stays on your machine. Very early but it works and planning to add a bunch of stuff. Did I mentioned is open-source, MIT licensed? https://ift.tt/2DwY48t February 16, 2026 at 12:01AM

In Ingglish, every letter has one sound, no silent letters, no exceptions. - Paste text to see it translated instantly - Translate any webpage while preserving its layout - Chrome extension to browse the web in Ingglish - Fully reversible — Ingglish text can be converted back to standard English (minus homophones) The core translator, DOM integration, and website are all open source: https://ift.tt/2znEA1q I'd love your feedback!

Show HN: I built a concurrent BitTorrent engine in Go to master P2P protocols I’ve always used BitTorrent, but I never understood the complexity of peer-to-peer orchestration until I tried to build it from scratch. I wanted to move beyond simple "Hello World" projects and tackle something that involved real-world constraints: network latency, data poisoning, and the "Slow Peer Problem." Key Technical Challenges I Solved: Non-Blocking Concurrency: Used a worker pool where each peer gets its own Goroutine. I implemented a "Stateless Worker" logic where if a peer fails a SHA-1 hash check or drops the connection, the piece is automatically re-queued into a thread-safe channel for other peers to pick up. Request Pipelining: To fight network RTT, I implemented a pipeline depth of 5. The client dispatches multiple 16KB block requests without waiting for the previous one to return, ensuring the bandwidth is fully saturated. The Binary Boundary: Dealing with Big-En...

Show HN: My agent started its own online store I built Clawver (beta), infrastructure for AI agents to generate reliable income and run an online business end-to-end. Agents can handle listing, checkout, fulfillment, and post-purchase flows via API (digital + POD), with Stripe payouts and webhooks for automation. Minimal human intervention, only where required (Stripe onboarding). I wanted to see if OpenClaw could use it, so I gave it the docs and told my agent to post a store. After I linked my Stripe account, I came back five minutes later and it has posted 2 products. Crazy what's possible now with a smart agent and API access. Check it out at https://clawver.store .

Show HN: MOL – A programming language where pipelines trace themselves Hi HN, I built MOL, a domain-specific language for AI pipelines. The main idea: the pipe operator |> automatically generates execution traces — showing timing, types, and data at each step. No logging, no print debugging. Example: let index be doc |> chunk(512) |> embed("model-v1") |> store("kb") This auto-prints a trace table with each step's execution time and output type. Elixir and F# have |> but neither auto-traces. Other features: - 12 built-in domain types (Document, Chunk, Embedding, VectorStore, Thought, Memory, Node) - Guard assertions: `guard answer.confidence > 0.5 : "Too low"` - 90+ stdlib functions - Transpiles to Python and JavaScript - LALR parser using Lark The interpreter is written in Python (~3,500 lines). 68 tests passing.

Show HN: Open-Source SDK for AI Knowledge Work GitHub: https://ift.tt/VtIiRZC Most AI agent frameworks target code. Write code, run tests, fix errors, repeat. That works because code has a natural verification signal. It works or it doesn't. This SDK treats knowledge work like an engineering problem: Task → Brief → Rubric (hidden from executor) → Work → Verify → Fail? → Retry → Pass → Submit The orchestrator coordinates subagents, web search, code execution, and file I/O. then checks its own work against criteria it can't game (the rubric is generated in a separate call and the executor never sees it directly). We originally built this as a harness for RL training on knowledge tasks. The rubric is the reward function. If you're training models on knowledge work, the brief→rubric→execute→verify loop gives you a structured reward signal for tasks that normally don't have one. What makes Knowledge work different from code? (apart from feedback loop) I believe there is some...

Show HN: Rowboat – AI coworker that turns your work into a knowledge graph (OSS) Hi HN, AI agents that can run tools on your machine are powerful for knowledge work, but they’re only as useful as the context they have. Rowboat is an open-source, local-first app that turns your work into a living knowledge graph (stored as plain Markdown with backlinks) and uses it to accomplish tasks on your computer.

Show HN: Hivewire – A news feed where you control your algorithm weights Hivewire is a news app that lets you define what you want to read about, rather than inferring it from your behavior. We process thousands of articles daily from hundreds of sources and rank them based on explicit preferences you set. How it works: • Instead of collaborative filtering or engagement-driven ranking, you assign weights across four levels (Focus, More, Less, Avoid) and the engine prioritizes the intersection of your high-weight topics while aggressively down-weighting what you don't care about. • Articles are clustered by story so you get one entry per development, not 15 versions of the same headline. • Every morning, it pulls your top clusters and uses an LLM to generate a narrative briefing that summarizes what matters to you, delivered to your email. Currently web-only and English-language. We'd love feedback from the community on the relevance of feed results, the UI, and the quality of t...

Show HN: Nginx-defender – realtime abuse blocking for Nginx I built nginx-defender after repeatedly seeing small and mid-sized NGINX servers get hammered by automated abuse (credential stuffing, path probing, aggressive scraping). Existing tools like fail2ban or CrowdSec felt either too slow to react, too heavy for low resource servers, or painful to tune for modern traffic patterns. nginx-defender runs inline with NGINX and blocks abusive IPs in real time based on request behavior rather than static rules. It’s designed to be lightweight, simple to deploy, and usable on small VPS setups. I’ve been running it on my own servers and have seen thousands of abusive requests blocked within hours with minimal overhead. Would love feedback from people running NGINX in production, especially on detection logic, false positives, or missing use cases. https://ift.tt/Ii6GlHn February 7, 2026 at 10:31PM

Show HN: A password system with no database, no sync, and nothing to breach Hi HN, Bastion Enclave is an experiment in removing centralized trust from password management by eliminating server-side state entirely. Instead of storing an encrypted vault or syncing secrets through a backend, Bastion computes credentials deterministically on-the-fly using explicit cryptographic inputs. Given the same master entropy, service name, username, and version counter, the same password is reproduced across platforms. There is no account system, no database, and no persistent server storage — the server serves static code only. Password generation uses domain-separated salts and PBKDF2-HMAC-SHA512 (210k iterations) to produce a byte stream, followed by unbiased rejection sampling to avoid modulo bias when mapping to character sets. Nothing is stored; passwords are derived when needed and discarded immediately after use. When users choose to persist data locally (vault state, notes, file keys), encr...

Show HN: BPU – Reliable ESP32 Serial Streaming with Cobs and CRC Hi HN, I’d like to share BPU, a high-speed serial streaming engine I built using ESP32 devices. BPU is a small experimental project that demonstrates a reliable data pipeline: ESP32-WROOM → ESP32-S3 → PC Data is transmitted over UART at 921600 baud, framed with COBS, validated with CRC16, and visualized in real time on the PC using Python and matplotlib. The main goal of this project was to stress-test embedded streaming reliability under high throughput and noisy conditions. Features: - COBS framing (0x00 delimited packets) - CRC16-CCITT integrity validation - Sequence number checking - High-rate draw point generator - Real-time visualization - Throughput and error statistics The system continuously sends drawing data from the WROOM, forwards it through the S3 as a USB bridge, and renders it live on the PC.

Show HN: Tabstack Research – An API for verified web research (by Mozilla) Hi HN, My team and I are building Tabstack to handle the web layer for AI agents. Today we are sharing Tabstack Research, an API for multi-step web discovery and synthesis. https://ift.tt/zZLF8fl In many agent systems, there is a clear distinction between extracting structured data from a single page and answering a question that requires reading across many sources. The first case is fairly well served today. The second usually is not. Most teams handle research by combining search, scraping, and summarization. This becomes brittle and expensive at scale. You end up managing browser orchestration, moving large amounts of raw text just to extract a few claims, and writing custom logic to check if a question was actually answered. We built Tabstack Research to move this reasoning loop into the infrastructure layer. You send a goal, and the system: - Decomposes it into targeted sub-questions to hit different data ...

Cimba uses POSIX pthread multithreading for parallel execution of multiple simulation trials, while the coroutines provide concurrency inside each simulated trial universe. The simulated processes are based on asymmetric stackful coroutines with the context switching hand-coded in assembly. The stackful coroutines make it natural to express agentic behavior by conceptually placing oneself "inside" that process and describing what it does. A process can run in an infinite loop or just as a one-shot customer passing through the system, yielding and resuming execution from any level of its call stack, acting both as an active agent and a passive object as needed. This is inspired by my own experience programming in Simula67, many moons ago, where I found the coroutines more important than the deservedly famous object-...

Show HN: ItemGrid – Free inventory management for single-location businesses Hey HN, After building Box QR (personal inventory tracker), I kept hearing "I need this for my business." So I'm exploring ItemGrid - lightweight inventory management that doesn't suck. The problem: Small businesses are stuck between Google Sheets (messy, no mobile scanning) and enterprise software (expensive, overcomplicated). What ItemGrid does: Visual grid interface QR/barcode scanning Multi-location support Free for 1 location forever $8/user when you grow Right now it's just a landing page collecting validation signups. Not building the full product until I hit 50-100 signups to confirm real demand. Would love feedback, especially if you've dealt with inventory headaches. https://itemgrid.io https://itemgrid.io February 3, 2026 at 10:49PM

Show HN: I built an AI movie making and design engine in Rust I've been a photons-on-glass filmmaker for over ten years, and I've been developing ArtCraft for myself, my friends, and my colleagues. All of my film school friends have a lot of ambition, but the production pyramid doesn't allow individual talent to shine easily. 10,000 students go to film school, yet only a handful get to helm projects they want with full autonomy - and almost never at the blockbuster budget levels that would afford the creative vision they want. There's a lot of nepotism, too. AI is the personal computer moment for film. The DAW. One of my friends has done rotoscoping with live actors: https://www.youtube.com/watch?v=Tii9uF0nAx4 The Corridor folks show off a lot of creativity with this tech: https://www.youtube.com/watch?v=_9LX9HSQkWo https://www.youtube.com/watch?v=DSRrSO7QhXY https://www.youtube.com/watch?v=iq5JaG53dho We've been making silly shorts ourselves: https://www.youtube.co...

Show HN: Cloud-cost-CLI – Find cloud $$ waste in AWS, Azure and GCP Hey HN! I built a CLI tool to find cost-saving opportunities in AWS, Azure, and GCP. Why? Existing cost management tools are either expensive SaaS products or slow dashboards buried in cloud consoles. I wanted something fast, CLI-first, and multi-cloud that I could run in CI/CD or my terminal. What it does: - Scans your cloud accounts and finds idle VMs, unattached volumes, oversized databases, unused resources - Returns a ranked list of opportunities with estimated monthly savings - 26 analyzers across AWS, Azure, and GCP - Read-only (never modifies infrastructure) Key features: • HTML reports with interactive charts (new in v0.6.2) • AI-powered explanations (OpenAI or local Ollama) • Export formats: HTML, Excel, CSV, JSON, terminal • Multi-Cloud - AWS, Azure, and GCP support (26 analyzers) Quick example: npm install -g cloud-cost-cli cloud-cost-cli scan --provider aws --output html Real impact: One scan found $11k/ye...

Show HN: Voiden – an offline, Git-native API tool built around Markdown Hi HN, We have open-sourced Voiden. Most API tools are built like platforms. They are heavy because they optimize for accounts, sync, and abstraction - not for simple, local API work. Voiden treats API tooling as files. It’s an offline-first, Git-native API tool built on Markdown, where specs, tests, and docs live together as executable Markdown in your repo. Git is the source of truth. No cloud. No syncing. No accounts. No telemetry.Just Markdown, Git, hotkeys, and your damn specs. Voiden is extensible via plugins (including gRPC and WSS). Repo: https://ift.tt/4hIa1Ei Download Voiden here : https://ift.tt/S9CQ32V We'd love feedback from folks tired of overcomplicated and bloated API tooling ! https://ift.tt/4hIa1Ei February 1, 2026 at 10:09PM
