Show HN: Play Chess. Earn coins. Build an army Hi there. I'm testing this hypothesis with new chess rules. These changes to the rules can be easily brought to offline games as well. Also if you are brave and have an Apple device here is the link to TestFlight to play with mobile version https://ift.tt/rGWkgtS https://chesspoly.com/ August 12, 2026 at 01:39AM

Show HN: Woxi - Open-source Mathematica / Wolfram Language reimplementation https://ift.tt/ZVbldtx

Show HN: Woxi - Open-source Mathematica / Wolfram Language reimplementation Woxi is an interpreter for the Wolfram Language written in Rust. It comes with Woxi Studio, a Mathematica-like GUI built with iced, but you can also use Woxi through a CLI, Jupyter kernel, Python package, npm package, or WASM module. Compared with wolframscript / Mathematica, the main differences are: - Free and open source - Very fast startup - Typically milliseconds rather than seconds for the Wolfram kernel, making Woxi practical for shell scripts, one-liners, and other short-lived processes - Embeddable - It can run in a browser via WASM or be embedded into another application as a scripting language A more detailed comparison with Mathematica is available here: https://ift.tt/UngQ4pk . Conformance is ensured with ~26'000 unit tests and ~900 .wls script snapshot tests. The current focus is on fixing remaining edge cases, improving performance, and growing the community. If you use the Wolfram Language, I'd be particularly interested in feedback on compatibility and missing functionality. Contributions and bug reports are also very welcome: https://ift.tt/BHcD3Ot https://woxi.ad-si.com August 12, 2026 at 12:06AM

Show HN: Tesserae, self-hosted dashboards for e-ink panels https://ift.tt/Eva871K

Show HN: Tesserae, self-hosted dashboards for e-ink panels Hi all, This is a project I’ve been working on for the last 10 or so weeks. Tesserae is a self-hosted dashboard server for e-ink panels. It allows you to build dashboards in two ways. A card-based editor that lets you tessellate different widgets side by side in resizable cells. Or a canvas editor which lets you drag and drop elements on a free-form canvas. You can also drive the canvas editor via MCP for some highly detailed dashboards. I fell down this rabbit hole after impulse buying a 13.3” Spectra 6 display. I knew I wanted to write my own software for it. I wanted something user-friendly, extensible, and able to host multiple displays. This drove the drop-a-folder architecture. Adding widgets, themes, devices, and renderers involves just dropping a folder into Tesserae. Tesserae ships with over 30 widgets pre-installed, plus a community marketplace that hosts many more (admittedly most of those are my own builds). This began as a solo project but has grown into a small community with people contributing firmware for new hardware, bug fixes, features, and even an open-source iOS app. Right now Tesserae supports over 10 different panels/devices. None of this would have been possible without AI assistance. I should also add that Seeed sent me hardware for development, but no money changed hands. Tesserae is AGPL and has a few rough edges, so issues and PRs are welcome. Thank you! https://tesserae.ink/ August 11, 2026 at 01:27AM

Show HN: OpenClimbing v2.0 – OSM+Wikimedia climbing guide https://ift.tt/wmdDaeZ

Show HN: OpenClimbing v2.0 – OSM+Wikimedia climbing guide Hey HN, jvaclavik here from OpenClimbing team! We are thrilled to release version 2.0 of our fully opensource/opendata climbing guide. Based on OpenStreetMap for map-data and Wikimedia Commons for images, we created a (hopefully) user-friendly app which completely uses these open databases, thus contributing data back to commons. We designed a simple and powerful notation for drawing climbing routes directly over the Wikimedia pictures: - https://ift.tt/fMSgKuB... Check out the release article for a ton of new features, or go directly to the web at https://ift.tt/HoWuFq2 We would love to hear feedback from fellow hackers and open-data enthusisats. https://ift.tt/EIuaQbX August 10, 2026 at 11:47PM
