Show HN: Two-Dimensional Phase Portrait Plotterhttps://haraldrevery.com/notebook_pages/2dphaseportraitHi! I made a two-dimensional phase portrait plotter website page.Purpose: If you don't have any study guide for exercises related to dynamic systems or too lazy to run python and set up sliders to visually see potential bifurcations, you can play around with said dynamic system (numerically) to visually get a feel of the system.It includes numerical approximations for:- Euler/4th Order Runge-Kutta solver for the system --> You can also pick initial point + backwards integration.- Poincaré Index (index theory)- Nullclines- Eigenvalues of the Jacobian matrix (sometimes called "stability matrix" in the literature)It's based on old python code that I made for a dynamic system course that I converted to JavaScript using Grok, Sonnet 4.5 and Gemini Pro.Does not include:- Bifurcation diagrams - can't make it without a computer algebra system (CAS), way above my skill level...- Anything that isn't two-dimensional (for one dimension you can just use a regular calculator) - 3D got highly computaFeb 14, 2026 1:35 PM

Show HN: Skill that lets Claude Code/Codex spin up VMs and GPUshttps://cloudrouter.dev/I've been working on CloudRouter, a skill + CLI that gives coding agents like Claude Code and Codex the ability to start cloud VMs and GPUs.When an agent writes code, it usually needs to start a dev server, run tests, open a browser to verify its work. Today that all happens on your local machine. This works fine for a single task, but the agent is sharing your computer: your ports, RAM, screen. If you run multiple agents in parallel, it gets a bit chaotic. Docker helps with isolation, but it still uses your machine's resources, and doesn't give the agent a browser, a desktop, or a GPU to close the loop properly. The agent could handle all of this on its own if it had a primitive for starting VMs.CloudRouter is that primitive — a skill that gives the agent its own machines. The agent can start a VM from your local project directory, upload the project files, run commands on the VM, and tear it down when it's done. If it needs a GPU, it can request one. cloudrouter start ./my-project clFeb 13, 2026 7:02 PM

We're an Italian startup building a stablecoin yield app for everyday Europeans people who have never touched a wallet, don't know what Morpho is, and have no interest in learning.What we do today: Users deposit euros via cooinbase pay. We convert to USDC, split their deposit across multiple isolated Morpho vaults on Base chain (each with different collateral types and borrowers pledging 150-200% of what they receive), and they earn 4-7% APY. They see one number: their balance growing daily. No wallet, no gas fees, no tokens. We have apps built for both iOS and Android, currently in beta.The market context: This category is exploding in the US. Axal (a16z CSX, $2.5M), Nook (Coinbase Ventures, $2.5M, ~7.6% avg APY, built by ex-Coinbase/Uber team), YieldClub ($2.5M), and Aave itself launched a consumer savings app with up to 9% APY and $1M deposit protection.

So I built @SornicBot on Telegram - you send it any article URL and it sends back an MP3 you can listen to right inside Telegram.How it works:Open @SornicBot on Telegram Send any article link Get back an MP3 in seconds It extracts the article text (strips ads, popups, cookie banners), then converts it to natural-sounding audio. You get 3 free articles per day.Just forward an interesting article link to the bot and listen to it later.If you prefer a web experience, there's also https://sornic.com where you can:Choose from 6 different AI voices Queue up multiple articles for back-to-back listening Download MP3s for offline use Get HD audio quality with credits The bot is free to use with a daily limit.

After playing with time related concepts in various projects, I wanted to build an app of my own and made this using WebGL and React. This is my first ever app and I’m quite proud of this beta version.Try the full experience for free in any browser. No ads, just a beautiful clock you can run in a tab, window, or PiP while working or studying. (One-time purchase unlocks saving custom themes, settings, and presets and is usable on the web, app, or screensaver.) You can start by trying out some of the different preset styles and then customizing it to your preferences.Key features:• Show/hide seconds, Feb 12, 2026 12:52 PM

Show HN: Nomad Tracker, a local-first iOS app to track visas and tax residencyhttps://www.thenomadtracker.comHi HN, I’m full stack developer (formerly iOS) and I just launched Nomad Tracker, a native iOS app to help digital nomads track physical presence across countries for visa limits and tax residency.Key idea: everything runs on-device. No accounts, no cloud sync, no analytics.Features:- Calendar-based day tracking per country. - Schengen 90/180 and other visa “runways”. - Fiscal residency day counts and alerts. - Optional background location logging (battery-efficient, never overwrites manual data). - Photo import using metadata only (no image access). - On-device “Fiscal Oracle” using Apple’s Foundational Models to ask questions about your own data. Also you can choose AI models for this, but not local.I created this because other apps felt limiting and didn’t do what I needed. This app is visual, user-focused, and designed to make tracking easy and clear.Happy to answer questions or discuss the technical tradeoffs.Feb 11, 2026 6:12 PM

Show HN: Privacy-first iOS Keyboard with above-key predictionshttps://www.klava.space/Hey y'all, building Klava – an iOS keyboard inspired by BlackBerry, Windows Phone and other iconic aesthetics. It's pretty cool, I love it.It started because I missed BlackBerry keyboard's above-key predictions dearly. That is, suggestions are displayed above individual keys as you type, and you can flick them up to input words. Then came the realisation that I am violently nostalgic for the design languages of the past, when phones were fun – and have been looking for something like that on iOS for ages. Lastly, I realised that everything should be highly customisable and privacy-first because that's nice for me and for everyone.v1.2 now out with 25+ languages supported. Any Qs on the peculiarities (there are a ton) of building a custom iOS keyboard – feel free to shoot, and any thoughts & feedback.Feb 11, 2026 6:11 PM

Show HN: CodeRLM – Tree-sitter-backed code indexing for LLM agentshttps://github.com/JaredStewart/coderlm/blob/main/server/REPL_to_API.mdI've been building a tool that changes how LLM coding agents explore codebases, and I wanted to share it along with some early observations.Typically claude code globs directories, greps for patterns, and reads files with minimal guidance. It works in kind of the same way you'd learn to navigate a city by walking every street. You'll eventually build a mental map, but claude never does - at least not any that persists across different contexts.The Recursive Language Models paper from Zhang, Kraska, and Khattab at MIT CSAIL introduced a cleaner framing. Instead of cramming everything into context, the model gets a searchable environment. The model can then query just for what it needs and can drill deeper where needed.coderlm is my implementation of that idea for codebases. A Rust server indexes a project with tree-sitter, builds a symbol table with cross-references, and exposes an API. The agent queries for structure, symbols, implementations, callers, and grep results — getting back eFeb 11, 2026 1:10 PM

I built ClawHosters (https://clawhosters.com), a managed hosting platform for OpenClaw, the open-source AI agent framework.Quick timeline: domain registered February 5th. First paying customer six days later. I probably should have spent more time on it, but it works.If you haven't seen OpenClaw, it lets you run a personal AI assistant that connects to Telegram, Discord, Slack, and WhatsApp. Self-hosting it is absolutely possible, but it's a pain. You're dealing with Docker setup, SSL certs, port forwarding, security hardening, keeping the image updated. Most people don't want to deal with any of that. They just want the thing running.That's what ClawHosters does. You pick a tier (EUR 19-59/mo), click create, and you've got a running instance with a subdomain. About 60 seconds if we have prewarmed capacity, maybe 90 seconds from a cold snapshot.Some technical details that might interest this crowd:*Subdomain routing chain.* Every instance gets Feb 11, 2026 11:35 AM

I wanted something that felt like a "neural extension" of my keyboard.It’s a macOS-native app that sits between your voice and your active window. Here is what it actually does:The Core Input Workflow:Push-to-Talk & Smart Send: Hold a global shortcut to speak. It detects the active app to determine the correct send method (e.g., Cmd+Enter for Slack vs Enter for Discord).Inline Editing: You can format while speaking. Need a line break, a specific spelling, or a bulleted list? You just say it, and it handles the formatting inside the sentence before outputting."Call Ghost": Post-processing commands (translate, polish, expand) are available immediately after speaking, before the text is typed out.The Experimental Stuff (WIP):1. Ghost Twin (Style Transfer): I call this a "Virtual Personality Engine" (a bit pretentious, I know). It analyzes your local writingFeb 11, 2026 6:35 AM

I can't help thinking that it's so obvious we are almost at the very top of this bubble - but here it feels like the majority of HN doesn't think like that...Yet just in 2026 we had:- AI.com was sold for $70M - Crypto.com founder bought it to launch yet another "personal AI agent" platform, which promptly crashed during its Super Bowl ad debut.- MoltBook-mania - a Reddit clone where AI bots talk to each other, flooded with crypto scams and "AI consciousness" posts. 250,000+ bot posts burning compute for what actual value?

Looking to improve taxonomy over time with ongoing missed matches/remaps where the automation was wrong.90-day price ratings - I've been collecting price data for a while now, so the site can tell you if a product is at its lowest price in 90 days () or within 5% of that low ().

(1) You don't have to figure out which webhooks you need or write listeners for each one. The library handles all of that. This follows the approach of libraries like dj-stripe in the Django world (https://dj-stripe.dev/). (2) Stripe's API has a 100 rpm rate limit. If you're checking subscription status frequently or building internal tools, you'll hit it. Querying your own Postgres doesn't have this problem. (3) You can give an AI agent read access to the stripe.* schema to debug payment issues—failed charges, refunds, whatever—without handing over Stripe dashboard access. (4) You can join Stripe data with your own tables for custom analytics, LTV calculations, etc.It creates a webhook endpoint in your Stripe account to forward webhooks to your backenFeb 10, 2026 5:14 PM
