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 https://bit.ly/3W1vn2W

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: 500 clocks in one 6.3 MB HTML file by Opus 5.5 Lately I've been testing frontier models by having them create self-contained web pages that display clocks--sort of my personal version of Simon Willison’s pelican-on-a-bicycle metric. I have been particularly impressed by the variety, interest, and quality of the clocks created by Claude Opus 5.5. Over the course of several sessions in the Claude chat interface, I had it build a total of 500 clocks.

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: Twain, a diff viewer like Meld, but for the age of AI I love Meld, I've been using it for a while now, it's amazing how many diff viewers exist these days and how they are all awful compared to Meld. But Meld was missing some features that I thought were worth having: - all files from a Git diff shown in the same view, sequentially + a file tree on the side. - show either the full files or only the parts that changed. - tree-sitter-based syntax highlighting. - the ability to comment on sets of changes and lines, and AIs can read these comments. - the ability to search through the entire set of modified files. Twain is in Rust and based on GTK4. https://bit.ly/4i2d1pY October 17, 2026 at 03:03AM

Show HN: Fakeipedia – Wikipedia for worlds that don't exist https://bit.ly/4hTgB6Q

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 https://bit.ly/4yot7jQ

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
