Show HN: Ordered – A sorted collection library for Zig https://bit.ly/3L8Iwlo

Show HN: Ordered – A sorted collection library for Zig I made an early version of a sorted collection library for Zig. Sorted collections are data structures that maintain the data in sorted order. Examples of these data structures are `java.util.TreeMap` in Java and `std::map` in C++. These data structures are mainly used for fast lookups (point search) and fast range searches. The library is available on GitHub: https://bit.ly/47Ja2hY October 28, 2025 at 06:26AM

Show HN: Easily visualize torch, Jax, tf, NumPy, etc. tensors https://bit.ly/3L6JezD

Show HN: Easily visualize torch, Jax, tf, NumPy, etc. tensors hey hn, wrote a python library for myself to visualize tensors. Makes learning and debugging deep learning code so much easier. Works seamlessly with colab/jupyter notebooks, and other python contexts. It's built on top of the graphics backend, chalk ( https://bit.ly/42XIAKW ). why? Understanding deep learning code is hard—especially when it's foreign, because it's hard to imagine tensor manipulations, e.g. `F.conv2d(x.unsqueeze(1), w.transpose(-1, -2)).squeeze().view(B, L, -1)` in your head. Printing shapes and tensor values only get me so far. tensordiagram lets me quickly diagram tensors. Other python libraries for creating tensor diagrams are either too physics and math focused, not notebook-friendly, limited to visualizing single tensors, and/or serve a wider purpose (so have a steep learning curve). https://bit.ly/3L8oSpD October 27, 2025 at 10:30PM

Show HN: Learn Basic Chess Movements https://bit.ly/4hw3ir5

Show HN: Learn Basic Chess Movements I made this basic website for my daughter (6) to learn how to move chess pieces. I wanted a simple game which didn't have all the rules, just how to get from A to B with a piece. Admittedly, as soon as I made this a friend pointed out https://bit.ly/47aSZW3 which is really nice! There are a bunch of settings you can tweak to set the difficulty etc. Anyway, maybe will be a fun (short) diversion. https://bit.ly/4htx6ol October 27, 2025 at 12:32AM

Show HN: Helium Browser for Android with extensions support, based on Vanadium https://bit.ly/47cCclm

Show HN: Helium Browser for Android with extensions support, based on Vanadium Been working on an experimental Chromium-based browser that brings 2 major features to your phone/tablet: 1. desktop-style extensions: natively install any extensions (like uBO) from the chrome web store, just toggle "desktop site" in the menu first. 2. privacy/security hardening: applies the full patch sets from Vanadium (with Helium's currently wip). Means you get both browsers' excellent privacy features, like Vanadium's webrtc IP policy option that protects your real IP by default, and security improvements such as JIT being disabled by default, all while being a reasonably efficient FOSS app that can be installed on any (modern) android. It's still in beta, and as I note in the README, it's not a replacement for the full OS-level security model you'd get from running the GrapheneOS Vanadium combo. However, goal was to combine privacy of Vanadium with the power of desktop extensions and Helium features, and make it accessible to a wider audience. (Passkeys from Bitwarden Mobile should also work straight away once merged in the list of FIDO2 privileged browsers) Build scripts are in the repo if you want to compile it yourself. You can find pre-built releases there too. Would love any feedback/support! https://bit.ly/4hqrCuu October 26, 2025 at 11:41PM

Show HN: Zoto – low-level audio playback in Zig https://bit.ly/4ow2JzQ

Show HN: Zoto – low-level audio playback in Zig I wanted a simple library to handle audio playback. Coming from Go, I was used to the `oto` library but I couldn't find a similar library in Zig. So this is a loose port of `oto`. It runs on macOS, Linux, and Windows. Supports memory playback, file streaming, and leverages the new `std.Io.Reader` interface in Zig. https://bit.ly/43BO126 October 26, 2025 at 05:13AM

Show HN: NickelJoke – Pay a Nickel to Get a Joke Using X402 Micropayments Since everyone’s talking about x402 now, I figured I’d open-source my NickelJoke project. It’s built on top of the Coinbase + Next.js x402 Starter and lets you pay a nickel for a joke. It’s a simple app, but it’s a fun way to explore the protocol and experiment with building and monetizing microservices on top of it. https://bit.ly/4qjs0yW October 26, 2025 at 12:55AM

Show HN: I made a simple portfolio performance calculator and it seems to work https://bit.ly/3L7E863

Show HN: I made a simple portfolio performance calculator and it seems to work Hello, this is my first project! I used nothing but free web tools. And it seems to work. I couldn't find a simple portfolio performance tool on the web, where I could just paste cash inflows, outflows and current value of my portfolio and get the portfolio performance calculated. Everything I found was in some way cumbersome and cluttered with ads. I used Perplexity for the coding and Codeberg for the hosting. I verified the output manually for some examples and all seems fine. Maybe it is useful for others too. If anyone can spot a problem in this small project, I would be very grateful to hear about it. https://bit.ly/3L7E8mz October 25, 2025 at 08:27AM

Show HN: Postnix AI – Helps Indie Hackers Get Their Work Seen https://bit.ly/3WpG38v

Show HN: Postnix AI – Helps Indie Hackers Get Their Work Seen Hi HN , Six months ago, I built JustGrind, an AI habit coach. Coding it was fun; shipping it? Nightmare. Marketing it? Even worse. I realized the hardest part of building a product isn’t the coding—it’s getting people to actually see it. So I built Postnix AI, a tool that helps indie hackers, creators, and solo founders craft posts that get attention: - Fetches top-performing posts in your target communities - Analyzes what makes them work - Helps you write your own posts that feel natural and hit the right vibe - Suggests flairs, formatting, and style tweaks that increase visibility and engagement Key lesson: no matter how good your product is, if nobody knows it exists, it doesn’t matter. It’s still early days, but people are already getting traction with their posts. Would love feedback from the HN community!

Show HN: Wsgrok – one of many ngrok alternatives https://bit.ly/4oAYtiw

Show HN: Wsgrok – one of many ngrok alternatives I built it for myself because ngrok didn't let me add one more domain unless I paid $12 more. I probably should've looked for alternatives before building my own, but my grudge got in the way . Once I started, I wanted to make it better than the other options. Silly, I know. No one probably cares. I plan to open source it sometime next year because I’ve got other projects to finish first. It's free until I deplete my cloud credits, then it will switch to a tier-based model with a free option. https://bit.ly/4nszhdb October 25, 2025 at 12:46AM

Show HN: Seed3D – Generate Physics-Ready 3D Models with Millimeter Precision https://bit.ly/3Jt7xan

Show HN: Seed3D – Generate Physics-Ready 3D Models with Millimeter Precision I built Seed3D, a next-generation 3D reconstruction and modeling tool that turns 2D inputs into solid, physics-ready 3D models — with millimeter precision, physically accurate PBR materials, and export formats ready for any major engine. Unlike traditional photogrammetry or AI mesh tools, Seed3D doesn’t fake geometry with normal maps — it reconstructs real surfaces, edges, and micro-details for simulation-grade accuracy and realism. What it does • Generates watertight polygonal meshes with crisp, true geometry • Outputs full PBR texture sets (albedo, roughness, metalness, normal, AO) • Delivers 6K textures that hold up in extreme close-ups • Ensures physics-stable topology for simulations and collisions • Exports USD/USDZ, FBX, and GLTF — compatible with Omniverse, Unity, and Unreal Engine Who it’s for • Embodied AI and robotics researchers • Game, XR, and VFX developers • Product visualization and digital twin creators • Simulation and graphics educators Try the Seed3D 3D model generator here: https://bit.ly/4osgwaw Would love feedback from the HN community — especially on fidelity, physics performance, and engine integration. https://bit.ly/4osgwaw October 24, 2025 at 06:25AM

Show HN: Onetone – A PHP full-stack framework with AI runtime, ORM, CLI Hey HN, I built Onetone Framework as a full-stack PHP framework that pushes the boundaries of what PHP can do. It’s fast, modular, and surprisingly capable — combining backend routing, ORM, CLI tooling, and frontend build support into a single developer-friendly experience. Highlights: - PHP 8.2+ with autowired routing and ActiveRecord-style ORM - Built-in CLI, Docker setup, and .env support - Frontend build pipeline with Vite, esbuild - Growing test suite covering routing, query building, crypto, math, UUID, and more It’s still experimental, but I’m excited about how far it’s come. Would love feedback on what feels over-engineered, what’s missing, and what could make it truly useful. GitHub: https://bit.ly/4qnbBcV October 23, 2025 at 01:16AM
