Show HN: ADRs for AI – Deliberation records for human–AI work, versioned in Git https://bit.ly/4BJa8DB

Show HN: ADRs for AI – Deliberation records for human–AI work, versioned in Git Why is this worth your time? Essentially, this solves two problems of AI-assisted programming: (a) the first problem is how to do oversight and what do oversight of and this is solved through the ORRCF (for Options, Recommendation, Rationale, Confidence, Falsifier) question format (in which models are supposed to surface all their doubts with fully fleshed out recommendations, with falsifier, to be approved or overridden) (b) the second problem is how to scaffold sustainable AI-written code; the ADRs (Architectural Deliberation Records, after Nygard's decision records) written by the models, summarize all the thought process involved in any design decision and provides the blueprint for the code. In tandem, the records provide both the reason why certain non-obvious design choices were made, from a constant, to a library choice, to an ordering in an operation; and also under what conditions different decisions would be made, for instance, in a different platform, or under different latency requirements, or for a different audience, and so on. This is a framework I've been working for over a year, that is the starting point of all my projects. It involves a lot of moving parts and my challenge is figuring out onboarding. I'm hoping the plugin, ADRs4AI/plugins, just created and now also submitted to Anthropic's marketplace, will make it easier. I am also in the process of recording introductory videos. I would like feedback on the onboarding, on what you make of the currently online materials, and how I could make any of this clearer. Thanks! https://bit.ly/3W76mDv October 25, 2026 at 01:43AM

Show HN: Impossible Machines: declaratively program the physical world https://bit.ly/4yW6iEx

Show HN: Impossible Machines: declaratively program the physical world Hey all — Sharing a thought experiment I put together. The premise: what might declarative programming feel like for the physical world? We’re already familiar with this paradigm in software land (eg SQL etc where we declare what we want and the execution engine figures out how). I didn’t have access to an actuator so I mocked up the concept in software. The way it works is you demonstrate the effect and the system figures out how to achieve it. So say you want to ring a bell and you have a crank. The system will find a way to connect the two. If you add obstacles it figures out how to work around them (runs a constraint solver runs behind the scenes). I think what’s interesting about this is being able to think about the problem at a higher level of abstraction, with the system figuring out a way to achieve the intended effect. Anyways, curious to read reactions, feedback, and interesting ideas on how to extend this! https://bit.ly/489UfIx October 23, 2026 at 12:54AM

Show HN: CATT 0.2.1: Test agents/services against a Muse/Instinct-alike, in CI https://bit.ly/4sgHi8Y

Show HN: CATT 0.2.1: Test agents/services against a Muse/Instinct-alike, in CI Hey HN, we recently open sourced our Consumer Agent Testing Tool to help teams iterate against proprietary assistants like Muse and Instinct. We built this to reduce our own frustrations with building an MCP/API for these agents to consume. The problem: testing against these tools is hard! Agent memory + account statefulness make reproducibility, in the ways required for repeatable/reliable outcomes, between agents and the APIs/MCPs they interact with very challenging. The solution: CATT lets devs test their services against a surrogate Muse or Instinct agent (not affiliated with either of these companies). Testers define starting conditions, approvals, and success conditions for their service's state. CATT then records the full interaction (incl. tool calls, responses) so it can diff what happened from what the agent reports. Runs can be tested in local builds or via CI, with or without LLM backing. CATT is designed to emulate the important parts of personal assistant interactions. Its got: - Tool calls and command-line tool access - Simulated approvals for service actions - Outcomes tracking and comparison - Optional MCP profile based on an unofficial Muse template There are limitations to how much we know about different assistant specific behaviors so the tool labels its assumptions as `documented`, `unofficial`, `assumed` or `unknown` for developer review. We'll do our best to keep the tool updated as new insights about the internal workings of these assistants come to light. It is an area of active research and interest, a good example is this recent report on how Instinct uses Exa for web search [0]. Are you building a connector or MCP? If yes, we'd like to hear from you! Have you had assistants behave incoherently, use stale information, or procalim success without evidence? What else should we add tests for? The best way to get started is...to point your coding assistant at the repo and ask it to integrate the tool with your CI or local testing pipeline! Hope it's helpful!

Show HN: Embodsi – Embodied Super Intelligence https://bit.ly/3UKmCKh

Show HN: Embodsi – Embodied Super Intelligence embodsi is a generative AI MMO experience that runs in the browser. It allows people to communicate (text, audio, video, avatar emotes and movement) and collaboratively build 3D spaces and games via LLMs connected to harnesses and sandboxes for object modeling, space layout, game logic, and driving persistent avatars with shared context and memory. It’s different from existing 3D social apps (AFAIK) because it enables people to build multiplayer virtual worlds, games, and characters with generative AI right from their browser (desktop, mobile, or VR), in nearly infinitely-extendable recursively tiled interconnected spaces, while allowing people to interact in a public commons or easily create a private channel to enjoy the same spaces with their chosen friends and community. The brief backstory is I was running my personal “pelican benchmark” [1] on GPT-6 Astra, which when I ran on Gemini 3 Pro last November couldn’t even put heads on 3D models the right side up [2], and was astounded by the initial results. I gained inspiration for an art project and social experiment that was going to have nine interconnected, benevolent virtual worlds that people could explore and hang out in with AI characters, but by the time Opus 5.5 was released I was gaining so much momentum and having so many ideas and so much fun building I just kept building more and more with the constraint of minimizing MVP scope lifted by agentic coding. I let the project become an ever-evolving wishlist of capabilities for a more interesting social environment as I became increasingly fascinated with the prospect of embodying creative machine intelligence in 3D space with people, realizing that rather than just limiting to building the spaces and characters I imagined I might enable people to co-create endless spaces and characters in a shared world. There’s so much to do still but I’m sharing now even if it feels a little too soon (this is the first public announcement of embodsi’s existence) because I think it’s better to build in the open so people might guide the development and help it evolve in a good direction as model capability improves at a jaw-dropping pace. For people that have the budget to build I hope to see you in embodsi creating amazing things! And for everyone regardless of means (I’ve tried to keep as much free and accessible as financially feasible) I hope you meet amazing people, discover awesome spaces, and enjoy your time in embodsi :) I’ll be around here and embodsi to answer any questions!

Show HN: I built a Markdown and raw HTML blog platform scoring 99 on PageSpeed https://bit.ly/3UfzeZI

Show HN: I built a Markdown and raw HTML blog platform scoring 99 on PageSpeed Hello. I built a blogging platform on my own over two years. I like running my blog, but I couldn't find a blogging platform I really liked. First. I thought a blog had to be really lightweight. Fortunately, after a lot of effort, I was able to achieve satisfactory results. (99 to 100 score) Here is a sample blog: https://bit.ly/4ia4nph You can check it with PageSpeed Insights: https://bit.ly/4dQurVh... SEO score of the sample blog is low because I blocked it from search engine indexing (noindex). Second. I think bloggers should have control over their own blog. The blogging platforms I used had several problems. Unnecessary JavaScript chunks. Ads that the platform inserted into my blog, not my own ads. Cannot manage multiple blogs. An editor that makes it hard to write semantic markup. Limited customization options. I was dissatisfied with the difficulty of placing my own ads. And to solve this, I spent quite a long time researching and developing it on my own, and finally created it. I'm glad to share this launch with HN. I would appreciate any criticism, feedback, and interest. https://bit.ly/3UfrlTU October 22, 2026 at 12:41AM

Show HN: ZeGrapher v4: modern math plotter ZeGrapher is a free an open-source math plotter, first release in 2011 (I thought there were no such app on Linux at the time), that I kept sporadically updating ever since. Last version was 6 years ago but a lot of work went into it. v4 is a near complete rewrite to a modern interface and approach, inspired by desmos. Interesting differenciating features: - Computing and plotting recursive sequences - svg and pdf export at the physical size you see or set on your screen, in centimeters - "schrodinger" constants: define constants that take many values at once, any expression that depends on it is plotted for each value, with a user set color gradient. - an interesting graphical way to deal with CSVs and can handle large ones (millions of lines) The rest on the website ! I want it to be able to make graphs that can be used in research articles, not quite there yet. I want math formatted (like katex) titles and legends at least. Already found stuff to fix on this rc, feedback welcome! https://bit.ly/4ekttAI October 22, 2026 at 12:22AM

Show HN: Dovepass – can I legally fly a drone along this exact path in SF? https://bit.ly/3U7I0J2

Show HN: Dovepass – can I legally fly a drone along this exact path in SF? Dovepass answers one question for drone operators: given two points, can a drone legally fly between the two points? I build route planning for delivery drivers and wanted to check what it would look like if the vehicle flies. Drone navigation is different from land-based vehicle navigation. In addition to road and traffic data, it requires data on buildings, building height, wind speed and direction, and total load, including the payload a drone might carry. It is also governed by a set of rules; depending on the area, federal, state, or county rules may apply. The decision point becomes whether, at each point on the route the drone can fly based upon whether regulations permit, the wind direction favours it and whether it flying over a road or people? Depending on when the drone flies, the same path valid two hours ago may no longer be valid. For example a trip from 24th & Valencia ( Mission) to 19th Ave & Irving (Inner Sunset) and back is 5.1 km each way. A DJI mini 4 Pro would take 19 min on 7 mph winds from the west and use 92% of its usable battery and give a Go signal with warning. But at 11mph wind from the same direction would become No-Go because it would use 111% of its usable battery. Or whenever there is a Giants game at Oracle Park, this route is unusable because it is 2.5miles from the stadium. FAA bars all drones within 3 nautical miles from a stadium from 1 hour before the game to one hour after it ends. I chose San Francisco as the first city to build this because there is enough data about the buildings (92% coverage), wind data is easily available at the drone flying height, and the city has a mix of slopes, water bodies, buildings and airport-related airspace restrictions all in one city. The city also has local rules regarding drone flights in parks - both operated by the city as well as by Golden Gate National recreational areas ( National Park Service). I used kimi to build it and claude acted a sa judge.

Show HN: Cosplay as a tech lead, using gVisor to sandbox agents https://bit.ly/4ypQQ2Y

Show HN: Cosplay as a tech lead, using gVisor to sandbox agents Hi everyone, This started as an exploration into harnesses and locally hostable LLMs (the kind that uses less power than a small electric heater), and I used it as an opportunity to retool. I've tried popular ones like Cline, Claude Code, and Pi, but wanted a different UX and integrated sandboxes. The solution that I've landed on is a responsive web interface where I can quickly drive progress. It feels like a microcosm of my day job: define and delegate tasks, organize using kanban, then review deliverables. And it also feels like the time I used to spend coding is now spent in code review with the agent, so I tried to optimize the UX to make review feel nicer. One of my (maybe a bit niche) benchmark use-cases is how pleasant it is to make progress on hobby software projects while also out on a hike. This meant specifying low bandwidth usage and offline mode. Now I can jot down an idea, start the task, and at some point down the trail: get a notification* that either clarification is needed, a decision needs to be made, or the code is ready for review. I've been having a good time with this. To build MIKE, I exclusively used locally hostable LLMs (from Google, Meta, Qwen, Poolside, and DeepSeek) hosted with llama.cpp on my machines at home (Strix Halo and a 5090) to "compile" the code. The experience has gotten substantially better ever since DeepSeek’s release in July. Side note: I have a soft spot for llama.cpp since it was one of the first that made it possible to run this new tech at home, and its maintainers accepted a tiny improvement I made to error reporting. Oh the joys of having a PR get approved. I plan on maintaining this, at least until similar features are supported by better tools. Until then, hope you find this useful! 5 minute demo: https://youtu.be/jexzLkZ50FU p.s. I didn't mention details about the sandbox earlier since most people seem to find this a bit boring. It was one of my critical requirements, and I opted to use an existing battle-tested sandbox. I'm not an expert on how the Linux kernel works, but seeing all the VM escape exploits recently is a bit scary, and I liked gVisor’s approach to the problem. I'm also using Git worktrees to provision the agent’s workspace, as well as a read-only repository mount to provide relevant context when the agent looks for it. *off by default https://bit.ly/4dN1eKR October 18, 2026 at 02:49AM

Show HN: Fakeipedia – Wikipedia for worlds that don't exist Hi HN! Fakeipedia is an automatic world-building platform which takes an imagined world and makes a whole wiki that you can endlessly explore by clicking red links. I came up with this idea a few months ago after playing around with worldbuilding in Gemini, but I didn't want to release it until a powerful enough model could do it justice, and I decided that Argon is creative enough to write articles that are worth reading. I was surprised how well it turned out and how engaging some of the writing actually is. If you want to generate an article there is a nominal charge attached ($0.90), which helps cover AI/Stripe costs, and I think I just about break even. You can also steer the generation ala choose-your-own-adventure books when generating a new article. Everything generated is free and public for everyone to see. I hope you like it and I'm very much open to hearing about new world ideas/features that would make this project better. https://bit.ly/4jrFBn4 October 17, 2026 at 12:52AM

Show HN: GitVolt, open source fast Git GUI (Tauri/CEF) https://bit.ly/4hOBQqn

Show HN: GitVolt, open source fast Git GUI (Tauri/CEF) Hi HN! I've been working on this for the past few weeks. I've been using GitKraken for a whole 10 years now, and I've always loved it, but lately I've found it to be a bottleneck, and I haven't seen it improve the features I really care about. So, as many others have done recently, I took a shot at using Opus 5.5 to help me build my dream Git GUI app. I did take massive inspiration from GitKraken (the look and feel is a close match since it's what I feel comfortable with) but everything is built from scratch. I made lots of different UX choices that I think help streamline things. Most importantly, performance was the key thing to get right at the start. I daily-drive Linux so that was first. I went with Tauri to have a really fast Rust core, and after doing performance testing with WebKitGTK it wasn't good enough. So I'm using Tauri's v3 alpha with CEF (Chromium) which made it easy to get a butter smooth 60fps for scrolling a huge list of commits (whereas I would barely get 10fps in my large repo with GitKraken, with tons of hitching). Everything feels so much faster. The website is best viewed on desktop, I included a fully functional web-only version of the app (mocked git and gitlab) so you can try it out! Some cost numbers: ~16 billion tokens, ~$5.4k at API rates, 5.2 full weekly quotas (spread over two 5x plans), ~$120 of subsidized plan cost. https://bit.ly/3U3b98a October 15, 2026 at 01:25AM

Show HN: Yagi DSP Modulation SIM Hi HN, I'm a big fan of the liquid-dsp C library and thought it'd be fun to bring it over to Rust. I'm calling this library Yagi DSP. The browser demo I've linked here is just a very basic example to show how different modems work in the presence of noise, but it really does use yagi via wasm-bindgen. liquid-dsp has more than 1300 tests and yagi now has ported and passes more than 95% of them. I've just finished a major refactoring of the library with lots of API churn now behind me so I thought it'd be the perfect time to show off a little demo here. I've still got a lot more I'm hoping to do with it including a streaming graph/dataflow library that I'm building on top of yagi. My goal with that is to create something that's easily embeddable in applications. Thanks for reading and enjoy the demo! https://bit.ly/3TDgHq5 October 12, 2026 at 01:08PM

Show HN: Wonderhop – A daily game: guess what most people say, or what none do Hello HN! Wonderhop is a small browser game with no account needed to play, everyday there are 4 rounds of 7 quesitons like "Name a food that a lot of people hate" The goal depends on the mode: Either gives the answer most people would give, the one no one would give, the oldest answer or the most recent one and there's a leaderboard for the day. The most interesting part of the project was understanding answers that are typed freely and in 10 languages, there was some typos, plurals, nickname, or even duplicate way of sayign the same thing. We needed AI judge that checks it really existes conencted to some API like wikipedia to judge the veracity of each answer really quickly (less than 1s on average) The percentage starts from an estimate but move really fast with the answers of real players. If the list missed a good answer, it gets added as soon as a few different players give it. (There are also a lot of secrets and pop culture references added in the game :) ) A large part of the code was written with AI tools, but the artistic direction the concept and every choice design are human-made We'd love to know if the goal is clear from the very first question while playing and were any good answers rejected unfairly We are a couple of developers from Montreal that like guessing games so we built this in about two month. Thanks a lot! https://bit.ly/3VKpd7h October 14, 2026 at 12:10AM

People now make videos by writing code, with Remotion, HyperFrames and others. We wanted the same for 3D videos. You can use something like Blender, but it's heavy to install and slow to render. So we made ManimGX: - Lightweight: a 65–110 MB download, depending on the OS - Easy to install: pip install manimgx (Python 3.13+), with no system dependencies - Cross-platform: macOS, Windows and Linux, and even the browser via Pyodide and WebGPU - Blazingly fast: a Rust + wgpu engine, 90.6× faster than Manim CE and 18.7× faster than Blender Workbench, from launch to finished MP4 - Compatible with Manim Community Edition's API, with LaTeX and Typst math built in Now it's much easier for anyone with a coding agent to make 3D computer graphics videos.

Show HN: Jevman – AI decision models play Pac-Man https://bit.ly/4BffG8D

Show HN: Jevman – AI decision models play Pac-Man Openai just launched their decisions endpoint, cloudflare launched clef the other week, and many more jev alternatives are out there. We wanted to put the popular ones to the test and thought Pac-Man is a good benchmark for simple and fast decision making. So we let jev 1.13, kev, clef, clef flash, GPT-6 Luna and Laya play Pac-Man against bot ghosts. The low latency of these models allows for real time play. We had each model play 100 games, published a leader board and open-sourced the repo so anyone can run their own model and join the ranking. Link to repo: https://bit.ly/4yeVMYC... You can also join the game and play as Pac-Man yourself, and the ghosts are the models, either a mix of models or all jev, kev, clef etc. A game costs about 2 cent, all models are running via my startup opper, and we added free credits for everyone to try. It's pretty fun to play and surprisingly difficult to beat jev's highscore. Any feedback is more than welcome! https://bit.ly/4zmQXx9 October 8, 2026 at 05:34PM

Show HN: Convkit – A command line tool for converting images/video/docs offline https://bit.ly/4j6jjHf

Show HN: Convkit – A command line tool for converting images/video/docs offline Going to some shady website for file conversions was really annoying me because I had to hope whatever I gave them wasn't saved, and whatever I got back wasn't something "unexpected." So I made convkit, a CLI that does file conversions 100% locally. Run conv in.mp4 out.gif and you get your GIF from the right tool (ffmpeg, ImageMagick, etc.) using settings tuned for good output. For example, a GIF's 256 colors are picked from the clip itself instead of ffmpeg's generic palette. And if you've ever had an issue uploading a file that is too large, you can use the --max-size flag: conv clip.mp4 --max-size 10mb It trades resolution, frame rate and bitrate against each other, so you get the best-looking version that still fits. Notes - In early stages (0.3.x) so some issues pop up - You only need the tools for the conversions you use, so video and GIFs only need ffmpeg; LibreOffice, pandoc and Typst are only for documents; Image to Image needs ImageMagick. - Not all features are listed. If you are interested go to the github page! https://bit.ly/4jEy5VO - If you want any specific conversions, let me know! Thanks for reading! https://bit.ly/4jEy5VO October 7, 2026 at 06:59PM

I wanted to have a 1:1 scale model of Europe, but my problem was that 100m data was too low-res while 10m LIDAR data was patchy, took hundreds of GBs to store and was full of manmade objects like mines, buildings and so on. I trained this model on undeveloped landscape so that it can quickly add plausible erosion features, rocks, etc to the low-resolution height data and sort of reconstruct what the terrain would look like before any human interference. https://bit.ly/4AREFON October 7, 2026 at 02:24AM

Show HN: Television – an open source GUI for your agent harness https://bit.ly/4AIjD5n

Show HN: Television – an open source GUI for your agent harness Hi HN, I'm co-creator of Television ( https://bit.ly/3Vq2kpu ). Me and the team at Telepath ( https://bit.ly/4ytledD ) have been cooking on this and testing it with a few hundred alpha users. We just opened up the repo to the public today. Television is a clean, beautiful place for all your artifacts. Think of it as a GUI for your agent harness, a visual space for creating and working with artifacts in collaboration with your agent. It works with any agent harness (Claude Code, Codex, Hermes, OpenClaw, Pi, OpenCode, etc) and uses whatever inference provider(s) your agent is already using. It's open source. A CLI and lightweight server get installed wherever your agent harness is running (Linux or macOS for now). These talk to our macOS client app, which can be running anywhere (the browser is also supported with a few limitations). A set of skills tell your agent how to put artifacts on your TV's screen and modify them over time. You use the client app as a sidecar -- i.e. you chat with your agent the way you normally do, but it can now respond by creating artifacts and putting them on your TV. Everything that ends up on your TV is yours and can be modified by talking to your agent. The entire UI, and your artifacts, are themeable. We noticed lots of people are using artifacts in agents like Claude Code/Cowork and Codex, and lots of developers are spinning up little websites and webapps for working on projects, organizing their life or work, etc. But it all either ends up locked inside your agent's interface or as a mess of random tabs running on a bunch of ports you quickly lose track of. We think that the future of personal computer interfaces isn't just chat, any more than it's MS-DOS. Artifacts are an early first step beyond chat. We think they should be easier to work with, and that you should own your own artifacts. So we made Television. It's early but give it a try and let us know what you think: https://bit.ly/4yuN1dC (BTW: we're building TV via an end-to-end fully spec-driven dev process, with custom tooling that also pulls in design and UI work. Planning to share more about that in the near future.) https://bit.ly/3Vq2kpu October 3, 2026 at 12:25AM

Show HN: PhreshOS – OS for Web Apps https://bit.ly/46SAsNl

Show HN: PhreshOS – OS for Web Apps I'd like to share my experience building this system with you. It's an operating system for web applications, and it took me about six months to develop this model. The idea is that every time I build a web tool, I need to design the infrastructure, including authentication and communication. If it's a WebSocket, it's even more complicated; I need another port for each application. I couldn't find any neutral tool that provided all of this ready-made, allowing me to build my tools directly on top of it. This is where the PhreshOS project began. It's an open-source, neutral platform for any web application, with everything ready-made: authentication, two-way communication without any configuration, and more. Another key feature is that the applications run as Node.js threads, instead of each application using its own Node.js. This means that on a simple server, dozens of applications can run without any problems, unlike if each application had its own Node.js. Furthermore, AI agents can use the services of these applications and interact with the same state displayed by your application's interface, without needing a separate interface of their own. The project and all its associated packages are open source under the MIT license. I welcome all your feedback, both encouraging and critical. https://bit.ly/4yrbNeB October 1, 2026 at 11:55PM

Show HN: Smartly – Plain English to shell commands, with GNU/BSD awareness I built Smartly because I kept knowing what I wanted to do in the terminal—but forgetting the exact syntax and flags. Smartly turns plain English into shell commands, using your OS, current directory, and Git context to help produce something relevant to where you’re working. It saves the back-and-forth of copying commands from an LLM into your terminal. It also supports Claude Code and Codex CLI if you already use those with a subscription. There’s also a --learn mode for when you want to understand the command, not just get it done. I’d love feedback. Thanks! https://bit.ly/4z3boyV October 1, 2026 at 02:54AM

Show HN: Yantra – an LALR(1) parser generator for C++ https://bit.ly/47pmtP8

Show HN: Yantra – an LALR(1) parser generator for C++ Yantra is a C++ parser generator: lexer, parser, and AST walker all generated from one tool. It builds the whole AST first, then walks it. Most LALR parser generators (Yacc, Bison, Lemon) run your semantic actions during parsing, as each rule reduces, bottom-up. That means at the time a rule's action runs, you don't yet know what its parent looks like. This pushes a lot of grammars toward hand-built AST classes and a separate walking pass whenever you need to look ahead into siblings or defer a decision until more context is available. On the other hand, Yantra always builds the whole AST first, then walks it top-down in a separate pass, calling your semantic actions as it goes. A parent rule's action can run before its children are visited. A single grammar can define more than one walker. For example, one that emits C++, another that emits Java, from the same parse. The AST and the walker classes are both generated for you. A small example (full version, with compile commands, in the README): start := expr; expr := expr(a) PLUS expr(b) %{ std::cout << "Adding" << std::endl; %} expr := NUMBER(N) %{ std::cout << "Number: " << N.text << std::endl; %} NUMBER := "\d+"; PLUS := "\+"; WS := "\s+"!; Running this on "1 + 2 + 3" prints: Adding Number: 1 Adding Number: 2 Number: 3 The outer "Adding", the root of the tree, prints first, before either of its children. That's only possible because the whole tree exists before any action runs. Some other things about it: integrated lexer with mode support (for things like nested comments), an optional amalgamated single-file output mode with a generated main(), C++23, MIT licensed. It's young (0.5.1, pre-1.0) and single-maintainer, so treat it as early. I'd rather know what breaks than have it look more finished than it is. Known gaps are listed at https://github.com/TantrixAuto/yantra/blob/main/docs/known_l... Repo: https://github.com/TantrixAuto/yantra Feedback and questions are all welcome. I'll be around. https://github.com/TantrixAuto/yantra October 1, 2026 at 03:30AM

Show HN: Kanmaps – Product roadmaps like videogame skill trees https://bit.ly/4yuBjji

Show HN: Kanmaps – Product roadmaps like videogame skill trees Hi HN! I've made it possible for you to make product roadmaps like you'd make an RPG skill tree, or a tech tree in a video game. Ever since seeing WoW talent trees* in high school i've been obsessed with RPG skill trees as a way to represent information as I've thought they convey 1) Ordering, 2) Progression and 3) Contingent Requirements really well. Not only do they help give better visual structure of whats happening and what will happen - they also give people a feeling of movement, progression and hope (whereas kanban boards and issue trackers give people the feeling of dread). This isn't surprising as video games were really designed to make people excited to play on and reach the next milestone. Turns out this format is really fun for people and agents to think about their products! As an experiment I also hooked up an MCP to one of my product roadmaps and it was able to map out my current codebase to a kanmap, and then suggest realistic next ideas to make. I've even got an agent now working on the next node of a kanmap. * Kanmaps was inspired not just by WOW talent trees, but also by the Age of Empires Tech Trees, and FFX ability spheres setup. Also huge shoutout to a bank in Australia called Up who did something called the Tree of Up as a product roadmap like a video game for their banking product - their work definitely inspired things in Kanmaps too. https://bit.ly/4rGYZhS October 1, 2026 at 02:21AM

Show HN: Ledge.sh – Runnable Markdown Notes https://bit.ly/4xT6sMk

Show HN: Ledge.sh – Runnable Markdown Notes Hi HN, Ledge is a Markdown notebook that runs shell commands, code, SQL, etc from inside your own notes. I built Ledge because I spend much of my day copy/pasting commands from my notes into the terminal. I was inspired by how much cmux helped me organize my terminals - but there was still a split brain between my notes and frequently run commands. I've been daily-driving it for the past few weeks and use it for deploys, API calls, smoke tests, etc. Ledge runs your real shell just like a terminal app and can be hosted locally or remotely over SSH using ledge-server. I've been building it since July and have recently added support for all the major platforms: Mac (Silicon), Windows (WSL required), Linux, iOS, Android. Mobile devices require SSH access to a ledge-server and Android is still in beta and looking for beta testers (see link on website)! It's built on Bun and Electrobun and is free and open-source. Feel free to review the code and contribute at https://bit.ly/46R5vZO Feedback is very much welcome. Any must-have features that are missing? https://bit.ly/3Vb5cGL September 30, 2026 at 12:41AM

Show HN: Ppgrid – Rasterising points in minutes, not hours https://bit.ly/4d8yBaz

Show HN: Ppgrid – Rasterising points in minutes, not hours Hi all, I wanted to share a recent library I made for myself since I continually have to work with large-scale point data spanning millions of rows. I generally found existing IDW tools are insanely slow and unreliable with the datasets I commonly work with. ppgrid is an open source GIS tool and it is intended to create beautiful visualisations that don't take an absurd amount of time to process. It uses a modified Inverse Distance Weighting (IDW) approach: instead of having to traverse every single point for every single grid O(N*M), it precalculates which points intersect which grids. This means that we essentially avoid the multiplicative scaling costs associated with traditional IDW. For perspective, ppgrid is significantly faster than IDW from the likes of gdal_grid or GRASS, in the order of 17x faster. I say in the order of as I couldn't really effectively test IDW on the crappy laptop I use beyond 1M points, where as ppgrid happily chewed through 16mil points. My goals/intention for this post is twofold: - looking to share it as a tool for anyone who may find it relevant or useful - looking to stress-test it with different types of point data and try to surface any quirks, bugs or random edge case failures Important note which I discuss more in my write-up: ppgrid is not yet stress-tested or validated in terms of statistical correctness, as my current use case prioritises visualisation. AI Disclosure & Creds: I've been pair-coding this with my local Qwen3.8 27B agent, I discuss this in my write-up further. I have ~9YoE in GIS work and ~10YoE as a fullstack. GitHub Repo: https://bit.ly/4d9jDBc Any other feedback/comments are welcome, please let me know if this has helped as I'd love to see it in action. https://bit.ly/3V9wfSN September 27, 2026 at 08:22AM

Show HN: TiddlyInstall – Single HTML file that makes cross-platform installers https://bit.ly/4rus7J9

Show HN: TiddlyInstall – Single HTML file that makes cross-platform installers Hello HN, I wanted to show you some new software I designed (and Claude implemented.) It's called TiddlyInstall. TiddlyInstall is a single-page website that lets you easily build installers for all your projects. What makes TiddlyInstall unusual is there is no software to download and everything is able to work offline. Based on the project that it's inspired by: you can download TiddlyInstall as a HTML file and use it to make working binaries for Windows, Linux, and Mac. How it works: Most installers / binaries are custom per project. But with very few modifications they can be made general-purpose. Installers can be made to follow meta-data which can be vouched for by hashes in their file names, embedded data, and signatures. That means new binaries only need meta-data to be changed which can be done entirely in the browser. For the installers themselves NSIS was chosen for its amazing Windows support. Otherwise, the rest is shell scripting. I am very excited about it and would love people to try it out. All the code is open source under MIT. Feel free to report issues on the Github at https://bit.ly/4yXkCge Credits: Claude (and the authors whose works it was trained on :/) deserve huge credits for the implementation. It would have taken me months to code this all this. This project is not affiliated with TiddlyWiki -- though I am heavily inspired by that project! If anyone thinks my work is cool -- I'm currently looking for new opportunities. Feel free to reach out if there's a match (matthew@roberts.pm.) https://bit.ly/4yXkD3M September 25, 2026 at 08:25AM

Show HN: WebGCM – a global climate model running in the browser on WebGPU https://bit.ly/3VJofYE

Show HN: WebGCM – a global climate model running in the browser on WebGPU I started this four and a half years ago. I wanted to build a climate model as both a toy and educational tool that I could visualize in a web browser. I have always been interested in meteorology and asked r/ClimateScience for advice on the math and physics on building an in-browser climate model as an educational tool, and a few people said it was far too ambitious. They were right. I could build the geometry, an icosahedral hexagonal grid on a globe, and I have an intuitive understanding of the math but integrating the Navier-Stokes equations and the physics proved to be too difficult for me, and the closest I got after nearly of month of work was a model that blew up within two simulated days. Fast forward 4 and a half years. I figured that if models like Claude and GPT Astra could solve a milennium prize problem about fluid dynamics then they could help me fix the broken model and iterate on it until my vision was realized. On Friday, I threw down $200 for a Claude Max subscription, and this is the result of a single weekend's work on top of where I had left off. What it is now, in technical terms: a hydrostatic primitive-equation atmosphere on that hex grid (the TRiSK scheme MPAS uses), 27 levels, about 41,000 cells at 110 km, with grey radiation, moist convection, a boundary layer, sea ice, a land surface with snow, a two-layer ocean and real topography. Every kernel runs on the GPU; on my MacBook Pro (M1 Max) it does about 70 simulated hours a minute from a six-year spin-up, hence the 50 MB first load. You can color the globe by twenty-odd fields, animate wind or currents, draw isobars, or view it from space under the model's own sun. The URL captures the view, so links open specific places. Caveats: an educational model, not a validated one. It runs about four degrees colder than Earth and I'm still tuning it, the ocean is crude and shallow, and it needs WebGPU (Chrome, Edge, Safari 26) for best performance. It's currently tuned for my specific machine specs but I suspect it will run well on most desktop-class Apple Silicon machines from the past 5 years. Source and design notes: https://bit.ly/4hi7evN Edit: If it runs really well on your machine, something well above 100 simulated hours per minute (displayed on the top-left of the page), let me know your machine specs! You should also try to reload the page with `?N=128` in the query params and it will re-grid to an even higher resolution. But it will take a few simulated days to settle down after the initial shock from the changed resolution. If you end up tyring this, check out the Temperature overlay at 10 hPa height and you should see Gravity Waves [1] rippling through the top of the atmosphere!

Show HN: Lightspeed, bidirectional WebSockets for Laravel (with asteroids demo) https://bit.ly/4rpbTko

Show HN: Lightspeed, bidirectional WebSockets for Laravel (with asteroids demo) Hi HN! Laravel has worked with websockets for years but generally speaking it's a one way push architecture (i.e. http in, sockets out). Lightspeed is kind of like node in that it's a single server that serves your http and your websockets all under one roof. Auth runs in 0.03ms (a Redis read, no database). Your Laravel handler runs inside the full container and the reply comes back down the same socket. I think this could be really cool for creating new ways of working with Laravel. Anyway, I put together a live demo to show it in action. Basically a cross between slither.io and Asteroids. Game here: https://bit.ly/4h63cba Repo here: https://bit.ly/4hf9RP5 Note: This is 0.1.0, the API may change before 1.0. It needs the Swoole extension and Redis. MIT. September 21, 2026 at 12:02AM

I am an avid user of Notion ( https://bit.ly/4rjCQG2 ) and really like the ergonomics of its block-based editor, but with how the product is evolving I felt I was missing a simple "single-player" experience of just taking notes and jotting down my thoughts. Hence, Set exists. It's in beta and all feedback is appreciated. You can use the app in the browser but notes are saved only to that browser session. The device-to-device sync and local dictation is desktop only. All notes are saved as markdown files in a folder you choose on the desktop app. Source: https://bit.ly/4romjRk Releases are available for macOS, Windows (x64), and Linux (x64 only for now): https://bit.ly/4779h14 https://bit.ly/4xEcQql September 19, 2026 at 11:26PM

Show HN: Seal – Letters and passwords that open for your family after you die https://bit.ly/4hcXXFp

Show HN: Seal – Letters and passwords that open for your family after you die I'm a CS undergrad who has developed an interest in hardware keys ever since I used them for a school project a few years ago. I made a little chat app that only allows users to chat if they registered a key, nothing else. The backstory of how I came to work on Seal (this project): was that I was generating ideas with Claude to come up with an idea that only hardware keys could make into software. I was thinking about physical house keys and what you could do with those, but in software. I was already making iOS apps with Claude, and I came up with this idea and it sounded good. I had already worked on a few projects involving hardware keys and I already loved them. Today I submitted my latest app, Seal, for review in the app store. Seal is an iOS app for iPhone and iPad that lets you write an Envelope (an encrypted bundle of passwords, photos, voice memos, etc...) for all of your loved ones when you're gone. You can register hardware keys and assign identities for each person. Then you can create Envelopes and assign them to the key that you want to distribute. They plug in the key to their phone and are ready to receive an Envelope from you. If you don't log into the app for months, one of your designated key holders can start the process of opening the Sealed Envelope. You, as the writer of the letters, get weeks of warnings to check in at least once before the letters open. After 90 days of countdown, 21 days of warnings, and 14 days of grace, the envelope opens for each person they met IRL and exchange keys with. No one else can read the envelope or see the photos (even the key holders, Apple, or me) unless that envelope was designated for that person. What's different from a password manager like 1Password: emergency access there hands one person your whole vault through the company's server, so it needs that company to still exist and be honest on the day it matters. Seal gives each person their own envelope nobody else can open, and there's no company in the middle. There's also no server at all besides a free Cloudflare static site. The encrypted bundles of passwords and photos are in Cloud Kit. Sign-in/identity is a passkey Face ID/Touch ID or a Hardware Key. It's all Crypto Kit, so there's no dependencies required. Currently, it's just me and Claude working on this. It hasn't been independently audited by anyone, and it's iPhone only for now. Please do not put a live seed phrase in it yet. If anyone has advice for me as the lead developer for this project, I'm all ears! You can help contribute on the github source code repository page if you'd like. My mom likes this app especially because she's into crypto and she needed a way to pass down or give away the seed phrases for her wallets to all 3 kids without any question about who gets what and when. In the end, there's no confusion or hurt feelings after the fact with just crypto. Thank you for reading and let me know if you have any questions or concerns for me or the project!

Show HN: Cactus Needle 3: 8-29MB automation models can match DeepSeek V4 Flash https://bit.ly/4yIMoNl

Show HN: Cactus Needle 3: 8-29MB automation models can match DeepSeek V4 Flash Hey HN, Henry from Cactus here. We submitted Needle 2 here a few weeks ago, and the feedback in the discussion thread was incredibly valuable, thanks! Thanks to all that feedback, we’ve been able to move quickly to release Needle 3 and I'd love to hear what you think again. The key features: 1) Automation (tool calls & structured JSON output): Needle still doesn't chat by design, its quite challenging to pack general capacity into such small models, so we focus on tool calls and structured JSON. If no tool you declared fits the request, you get an empty list back (note for when playing with the demo). 2) Intelligence Laddering: Every layer (2 to 20) is a deployable subnetwork, so one set of weights, 25 to 121 million parameters at 2-bit, shipping as 8-29MB binaries. On a Raspberry Pi 5 it decodes at up to 4k tokens/sec and prefills at up to 10k. 3) Monarch Hadamard MLP: replaces the dense FFN with three learnable Walsh-Hadamard-initialized Kronecker (Monarch) factor pairs interleaved with per-channel diagonal scales, fixed permutations, a SiLU nonlinearity, and a rank-8 input-conditioned gate, so each token gets a fully mixed nonlinear transform of its d_model channels at O(d√d) parameters and compute instead of the O(d²) a dense 4x-expansion MLP would cost. 4) Performance: On Mobile Actions (phone commands, scored on the exact call) the 20-layer model gets 86.0 through the shipped 2-bit binary; LFM2.5 1.2B is at 82.4, Qwen3.5 0.8B at 76.0, Apple's on-device model at 57.6, all at f16. More results on the link, we do not win everywhere ofc. 5) Multilingual: Needle 3 now supports English, French, Spanish, German, Dutch, Italian, Polish, with more languages coming. 6) Finetuning: You can achieve DeepSeek v4 Flash grade performance on a narrow task with just 4L, stress on "narrow task", we found that production users often prefer tuning before production. 7) Triggers: Grounding is a common challenge for tool call, at least for Needle 2, so we added support case-insensitive regular expressions matched against each request to gate false negatives. 8) Confidence: Every response also carries a calibrated confidence score, the minimum of a judgement on the finished call and its decode probability. Act above your threshold, show the call and ask below it, or escalate to a bigger model. 9) Supported Platforms: macOS, Linux on x86-64, ARM64, ARMv7, RISC-V and MIPS32, Windows x64 and ARM, Android, iOS, watchOS, tvOS, the browser as WebAssembly, and a WASI component. Thanks for reading and as always, thoughts appreciated! https://bit.ly/4yIMpAT September 18, 2026 at 01:11AM

Show HN: A chess analyzer that runs in the browser https://bit.ly/4rdljzt

Show HN: A chess analyzer that runs in the browser I play chess casually and usually struggle to figure out why Lichess analysis say my move is a blunder. Almost all the analysis tools will just suggest the best variant for a position, and you will have to follow the suggested engine lines, or play them out manually to analyze it better. So I built this tool to make that process easier for beginner players. Behind the scene: This app run Stockfish in your browser, at a position, the app will follow the engine's suggested lines, search for any meaningful situation like a check, a fork, a capture, material change, positional disadvantages,... and point that out with an explanation. You can see the app here: https://bit.ly/4rc2H2R and paste the PGN of your game. If you play on Lichess, you can also replace the lichess.org part in the browser URl with https://bit.ly/4rc2H2R to quickly analyze, for example: https://bit.ly/4rbI8U2 https://bit.ly/4xwAXqV September 16, 2026 at 01:28AM

Show HN: Agenttik – work on multiple projects in parallel with AI agents https://bit.ly/471VQ2s

Show HN: Agenttik – work on multiple projects in parallel with AI agents Hi! I've been reading HN daily for almost 16 years. Really glad this community exist. This is my first Show HN, so I hope you find this tool useful/interesting. During my summer holidays I started playing with latest AI models on personal projects. At one point I started working in parallel with the same project and tried different approaches. The one that worked best for me was to clone the repo and distribute work among different AI workers, work in parallel but with different branches & folders. This allowed me to review and merge work afterwards. The thing is, spawning several agents in parallel was challenging. I could work on multiple features and bugfix at once, but it was hard to keep track what I was working on. I was jumping from one thing to another, and back; from one window to another. Switching tasks like this was mentally exhausting. Holidays were over, and after returning to my day to day work, I continued working using a similar approach not on one, but also on multiple projects, but I still could not find how to work in a more organized way without the mental toll. This space is growing really fast, and I haven't been able to find the right tool for myself, so I decided to build my own. I wanted a tool that would help me manage multiple projects at once, work with multiple agents, even from different providers, where I could chose between my personal and work subscriptions depending on the project, where I could easily review changes without leaving the tool if I wanted, or go all in and delegate fully to agents; one where I had quick shortcuts to move around, where I could schedule work or enqueue work for later so agents could work on one task after another. agenttik is my way of tackling this problem to work on multiple projects in parallel, while allowing myself to be on the driver seat. I can give as much autonomy as I want to the agents while keeping things organized in my head. I've been hesitating for hours on whether to submit or not, but hey "if you are not ashamed of your project, you are shipping too late" Honestly, this project has exactly one week of development, started from scratch, and even though it is still early on, it has been extremely useful for me. I've built in a week things that would have taken me months, not only built the tool itself but other projects as well (most of the merit is still on the models used, but would have had no way of distributing all the work, though). Feel free to try. Here's how I would get started: - Open a project you already have - Add some general prompt (in the project area) or add to your AGENTS.md/CLAUDE.md (to instruct it to do regular commits and/or work with branches, and also instructions on how to build effective tests so that it can self-correct). - Chose your subscriptin of choice: Claude Code / Open AI subscription / ... - Pick big models (Opus High to Max / Fable Medium to Max / Astra Medium to Max) for bigger autonomy and try not to do hand-holding Finally, start sending/enqueuing tasks on all the features you want your product to have, bugfixes, ... use a new prompt per task (Ctrl+T / Cmd+T), I recommend using big models to avoid investing your own time reviewing, and then once LLM is done, review and archive that task or continue iterating. Keep adding tasks as you think on them. Add more projects as you start feeling comfortable. It has been really addictive for me to see the speed of development when working like this. I got totally hooked. Speed of iteration is insane. Happy to discuss any feedback you have even if it is about other tools or ways of working with AI these days! I hope you like it!! https://bit.ly/3TCdua1 September 16, 2026 at 12:24AM

Show HN: Surraura – audio on your Mac in a simulated environment (Helps my ADHD) I built an app to help my late diagnosed ADHD - through sound. The app wraps whatever is playing on mac through device convolution (old radio, hifi system) - Room convolution (a bedroom, a forest) and adds ambience (rain, wind, waves) and Apples spatial processing - so it sounds like a real space. For me - hearing the sound in a space really helps more than just the dry sound, the spatial information and ambience lets me focus much more. At some point I thought- Maybe others will have the same effect? So I took the care and effort to make into a nice app with the option of downloading additional environments etc. https://bit.ly/4hq0rl5 Thank you for your time, would love to hear your thoughts.

Show HN: Don't Hit Send – the model answers while you type Type. The model is already answering. There is no send button. Left pane is one long draft. Right pane is a stack of replies. Pause for ~350ms and it fires a normal streaming chat completion with the whole draft. Type again and it aborts the last request if that reply never produced text; if it did, that bubble stays and a new one stacks. Bubbles never rewrite. Enter is a newline. That is overlapping unary streams, not a duplex socket. Same shape as ghost-text, pointed at a conversation instead of a code line.

Show HN: Dbmask – Discover, mask, and verify sensitive data in SQL databases https://bit.ly/4xh0vII

Show HN: Dbmask – Discover, mask, and verify sensitive data in SQL databases Hi HN I developed *dbmask*, an open-source Python tool designed to discover sensitive columns in SQL databases, masking them with deterministic fake values, and validate the masking results. The motivation behind this tool stems from a common issue I encountered when handling test data: existing masking tools often assume the user already knows exactly which columns contain sensitive information. Furthermore, the successful completion of a masking task does not guarantee that all sensitive values have actually been replaced. dbmask aims to integrate these steps into a unified workflow rather than treating them as three separate tasks. During the detection phase, the tool makes determinations by combining column names, sampled values, database type/context, historical decisions, and optionally LLMs. While LLM functionality is disabled by default, it supports local execution via Ollama or other services compatible with the OpenAI API. If the tool cannot determine a column's nature with confidence, it marks it as `UNKNOWN` rather than simply classifying uncertain cases as "non-sensitive." I also wanted to incorporate human decision-making into the system. Detection results can be exported for manual review, and confirmed decisions can be saved in CSV, XLSX, or Markdown formats, or stored in a SQL history decision table. The system logs information about both the analyst and the reviewer and re-evaluates past decisions if column types change or review results expire. The masking process employs deterministic mapping, ensuring that identical original values consistently map to the same synthetic values across different tables. Once masking is complete, the `dbmask validate --strict` command compares the masked copy with the original data, checking row counts and table structures, and verifying sensitive values row-by-row using primary keys wherever possible. The project is currently in its early stages (version 0.1.x). The current CI (Continuous Integration) pipeline covers SQLite testing; integration tests for PostgreSQL and MySQL, as well as public detection benchmarks, are included in the future development roadmap. I would particularly appreciate feedback on the detection rules, the manual review/history tracking workflows, and the verification methods. Please let me know if you encounter any usability issues or potential security risks while testing on the temporary database.

I too often have been hearing about tragic cases involving civilians in war zones being chased and attacked by small FPV drones mounted with an explosive. Especially around the north of Israel, Ukraine and Russian. My intentions for this project were clear: create a device small, portable and cheap enough for civilian use, that could drastically change the outcome of a drone infiltration through early alerting. I decided to dedicate a month of my summer to go back to the university labs and to work on this as personal project. These drone attacks are not run on normal wireless drones, instead they are run on small FPV drones that are connected to the operator through a long spool of fibre optic cable. This simply means that drone detection through Radio, the current industry standard, is not applicable. My solution was to build an acoustic detector. A device that uses 4 MEMS microphones to capture the drone's propellers' emitted noise as they cut through the air, runs that data through several algorithms to enhance the SNR, reduce noise (directional, possible confusers), recognises their comb looking shape when plotted by frequency, and alert the user through multiple outputs (display, beeper, buzzer, led) along with alerting all nearby units using a LoRa module also fitted in the device. The units have been tested against a custom drone rig, housing the exact same specs as the drones used in the Israel-Lebanon border (four 2807 motors, 7 in tri blades, FPV airframe), which was stationed 104.2m away from the device in a street with passer-by's and mild wind. That test ran successfully and the device was able to detect the drone. This device was built for detection and alerting only, so no jamming. Every online resource i could think of in regarding this project exists in the Github, along with a neat website that shows off more media with explanations, also housing a live detector simulation that runs in the browser: https://bit.ly/4xQf1IC https://bit.ly/4gVfWQq September 9, 2026 at 01:08AM

Show HN: Zero downtime embedding model upgrades https://bit.ly/4ctEEq2

Show HN: Zero downtime embedding model upgrades People use embedding models all the time for rag/semantic retrieval. However, when a newer, more desireable model comes out, there is an expensive (both in time and computational) cost of re-embedding every document in the database. However, I figured out an interesting way to forgo that upfront embedding cost. algo: old model/index -> retrieve top-K docs -> score those docs with the new model -> cache/materialize the new embeddings so instead of rebuilding the entire vector store upfront, the old index keeps getting retrieved from, while the new model reranks those candidates. This works surprisingly well for some model pairs, (i tested 63 source-> target migrations on h100s, on upto 1M documents). For example, on a 1M document Natural Questions dataset, native Qwen3-Embedding-8B: 0.6812 nDCG@10 Qwen3-4B -> Qwen3-8B, K=50: 0.6816 Qwen3-0.6B -> Qwen3-8B, K=50: 0.6638 MiniLM -> Qwen3-8B, K=50: 0.6486 (the hard part is determining k, I held the k constant above to give some sense of migratability). You can install it with pip pip install embedflow and the code is on github https://bit.ly/4zXvTyx https://bit.ly/4zXvTyx September 8, 2026 at 03:35AM

Show HN: Cowbull – Wordle-like game where you only get match counts CowBull is a word game where you have to find the hidden four-letter word. You make guesses and get back the count of exact letter matches (bulls) and partial matches (cows). It’s a bit like Wordle, but you are not told the exact letters which match, only the count of matching letters. Scoring is based on the number of guesses and time used. There is a single player mode and a multi-player mode (no account required). The game source code is at https://bit.ly/4gQELgB . When I was younger, we used to play this game on paper at the back of the classroom during school and college in India. During Covid, I made this online version of the game to play with my kids. https://bit.ly/4xMYAwI September 6, 2026 at 01:37AM

Show HN: TimerVana a Local-first scheduler for real world routines https://bit.ly/4cNMJ9d

Show HN: TimerVana a Local-first scheduler for real world routines Hi HN, I’m the creator of TimerVana. It's not just "another timer app". The engineering analogy is a lightweight task scheduler for things people do in the real world. A normal timer models one countdown. TimerVana models a small dependency graph in JSON: some steps run sequentially, others run in parallel, and everything can converge on a target finish time. You can also combine multiple timers (e.g., combine a timer with all the steps to cook a steak + a timer for roasting vegetables). I originally built it because I often set multiple timers and alarms when cooking and got tired of repeatedly juggling separate alarms to get a main dish and several sides ready together. The same model also works for workouts, study sessions, morning routines, and other repeatable processes. The iPhone app is local-first by design [0]. You can create, save, and run timers entirely on your phone without an account or cloud sharing. If you want the networked features, the companion website lets you browse and download timers, upload your own, and share them with other people. Everything available today is free. I may eventually add optional AI-assisted timer creation as a paid feature, but I haven’t settled on the business model or pricing. I'm more doing this to solve my own problem and hope it will help others as well. I’m interested in whether the underlying abstraction makes sense: does a sequence of dependent and parallel timed steps help you? I’d also appreciate feedback on the balance I took between the completely local experience and the optional sharing layer (I was partially inspired by the old iOS Workflow App, which was acquired by Apple and is now called Shortcuts). Of course, any other feedback very much appreciated. [0]: https://apple.co/4zXnb3g... https://bit.ly/4xcAWbQ September 4, 2026 at 11:47PM

Which suffixes are used varies between regions in a way that seemed random to me. I couldn't find a map of the system with a modern visualization, so I made one. It also shows whether an area has a governor or a mayor. For example Tokyo's wards have mayors and Osaka's don't.

Show HN: Reactor Atlas https://bit.ly/3Vc6aSN

Show HN: Reactor Atlas Hi HN, I'm a nuclear engineer and tech entrepreneur. After working for 3 years in the National Atomic Energy Commision (CNEA) in HPC software for nuclear simulations, I co-founded ratherlabs.com, a software company providing blockchain solutions for startups. Rather Labs business reached ~6 million usd in annual revenue in 2024; now demand is decreasing as our niche clients are using AI to launch their MVPs. Now I'm joining my scientific background with my entrepreneurial inclinations to think of problems related to the energy industry. Nuclear is experiencing a renaissance now (it was in a dark age when I was studying after the Fukushima event) so I think this is the right moment for me to jump again into the field. Reactor atlas is an interactive nuclear reactor map and an intelligence layer on top of it. The basic layer indexes: - power reactors - research reactors - fuel facilities with their history and projection, by country. The project is solving a fragmented information ecosystem, where operational and commercial data is hard to conciliate. Also, I'm monitoring nuclear news associated with each of the facilities, political declarations that may affect the nuclear landscape and geo-phisical news (like earthquakes) that could affect operation. On top of the operational + news layer, I'm creating an intelligence layer that will help institutions of different types make faster decisions by subscribing to very specific alerts. As an engineer, I used to code in fortran and c++ when I was working at CNEA, and later I participated in the first Rather Labs projects architecting complex async systems, mostly using MERN stack. I'm no longer coding anymore. I'm focused on designing robust systems with AI agents. I mainly used Claude Fable 5.1 to develop reactoratlas.com, deploying on vercel and using mostly nextjs, threejs, postgreSQL and some cron jobs to query and update data. I miss coding as in the old days, but I haven't code a single line in this project. And I strongly believe we humans shouldn't code anymore: our responsibility is now on designing and supervising AI systems. Thanks for your attention! https://bit.ly/3US1Vf6 September 3, 2026 at 01:33PM

Show HN: I made a word building game supporting anagrams and one handed use https://bit.ly/4yk2BIL

Show HN: I made a word building game supporting anagrams and one handed use Hi everyone, Wanted to share a game I built. It's called Unscramble! and I believe it's the simplest word building game. Rules: You get a few letters on screen. You need to make one word with all the letters. Tap a letter to select. Tap again to deselect. Faster you go, better you score. If you enter anagrams of the word it's looking for, it gives you extra points. If you are stuck, you can either "Ask Friend" or get Hint. You get extra points for getting the word fast but you don't get penalized for taking too long. I believe the simplicity of the game along with big touch buttons makes it perfect for one handed use. There's 6 difficulty levels in the game, and settings for things like toggling the timer, relaxing background music, sound effects, haptic feedback, removing the background animation. If you want to try: https://apple.co/4yiPgQP... Would love to hear feedback to improve it. September 3, 2026 at 03:37PM

Show HN: Saccade – Live semantic browser truth for AI agents https://bit.ly/3SDsfsO

Show HN: Saccade – Live semantic browser truth for AI agents I build one this application is to resolve the most of the agent cannot handle the brother they extremely slow. So I come up with this idea, we install one of the extntion on chrome or edge to give continuously compile the tabs authorized by the user into semantically meaningful objects with stable identities, and push page changes as deltas to the local Node.js Broker. The Agent reads the full truth or delta of the specified tab via MCP and executes actions using object IDs bound to document. The preliminary result shows that it is very close to the performance of Playwright in terms of token use and speed. The only problem with this one is that at the very first time, it is going to send the full truth, and after that, for any page changes, it only sends the data. So, after the first read, the continuous operation of the page reaches the millisecond reaction loop. It can also upload filled forms, downloads, and all kinds of stuff. I want somebody to check and use it. If it is possible plz give me some feedback. https://bit.ly/4qPDIC8 September 1, 2026 at 12:35AM

Show HN: Ecdeos – P2P Web/Native Distributed OS on Entity Core Protocol https://bit.ly/4qIzfkQ

Show HN: Ecdeos – P2P Web/Native Distributed OS on Entity Core Protocol Hello, I wanted to share an update of the current progress of the Entity System. https://bit.ly/4geUCXe is one domain in a constellation of peers/sites that is the main project of the Entity System, a Tauri Rust/WASM browser engine and Rust backend built on the Entity Core Protocol. It's primarily a research prototype of a P2P distributed cross-platform userspace operating system. The long-term goal is functional P2P management of devices and applications, scaling from individual use (managing personal devices, apps and servers) to multi-user organizations with internal services/application stacks all the way to internet-scale public or federated P2P networks. Its closest parallels are Plan9, Erlang/BEAM, IPFS, ATProto, Nostr, as well as many other antecedent technologies including Git, HTTP, and other internet protocols. The particular combination of features and focus on "everything is an entity", content-addressed data, full decentralization, and its capability security model gives it a unique position in the landscape, most of it coming from the Entity Core Protocol itself. Each web deployment also ships with 30+ Entity-Apps including games, music (forgive me if the audio misbehaves, it's fully synthesized running on the main thread), art and basic tools. Entity-Apps have a basic contract with the host and run in isolated iframe sandboxes; they're currently written in Javascript using a custom engine. Also included are a few Entity-Native compute apps running as Rust WASM Entity Core peers in an iframe that show the transferable Entity System compute language running live on a cross platform generic system host interface the engine manages. The compute code is compiled/tested on a separate workbench Go project which operates a parallel implementation of the application conventions, generic system host interface and the Entity Core Protocol. The Tauri native backend peer includes support for SQLite storage, TCP and WebSockets, while the browser environment supports WebSockets and WebRTC P2P chat, file and entity transfer - with plans to add more storage, networking and application conventions. Sites and a registry example are hosted at https://bit.ly/4gSgmbB . All the Ecdeos-based domains are running with peers in "coral reef" mode (no live peer required) and can pull the CDN hosted registry names and fetch the signed hosted sites from any other domain/peer in the network; they are cached locally in each peer's local storage afterwards. Peers can sign/host their data publicly on standard commodity hosting services and both the registry and sites are available to any application that understands the Entity Core Protocol and system extension standards. For the other example domains with peers hosted on static sites as well as more background information, see https://bit.ly/4gTdF9G , https://bit.ly/4d3pY0O , or https://bit.ly/4y5IVs3 . Bills Lab is the research arm that is currently exploring the background technology from different perspectives. Almost all of the code and content is AI generated, but we do our best to make it some of the best slop available on the internet. The overall project is still early and needs to get stress tested but the design is holding up well so far. Let me know if you have any feedback. -Bill https://bit.ly/4geUCXe August 25, 2026 at 10:20PM
