Real problems people complain about online, pulled every morning and scored out of 100. Build, validate, or skip. How scoring works
Github has been down consistently over the last few months - does it make sense to switch to alternatives?

You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result.It currently supports around 1.4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others.The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned.Made in Haskell!

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 languageA more detailed comparison with Mathematica is available here: https://woxi.ad-si.com/docs/comparison/mathematica/.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://github.com/ad-si/Woxi

LuaCAD models solids in Lua rather than the OpenSCAD language, with operator overloading for CSG (`a + b`, `a - b`, `a * b`).It ships with a CLI and a desktop app, including a preview area and a text editor.I've always been a big fan of OpenSCAD, but the SCAD language itself is unfortunately quite cobbled-together and is a very poorly designed programming language.LuaCAD takes all the good parts of OpenSCAD and combines them with one of the best scripting languages. It has now completely replaced OpenSCAD for me, and I think it provides a better experience than OpenSCAD for all use cases. I'd love to hear any reasons why LuaCAD shouldn't fully replace OpenSCAD!It’s fully open source and you can find the repo here: https://github.com/ad-si/LuaCADTech stack:- It's implemented in Rust and uses mlua (https://github.com/mlua-rs/mlua) to execute the Lua code.- Uses OpenCSG (https://opencsg.org) for fast and correct rendering of the 3D models (like OpenSCAD)- Uses Manifold (https://github.com/elalish/manifold) to create the manifold triangle meshes- Native support for all BOSL2 functions (i.e. implemented in Rust for better performance)
