In plain words

sandbox.bio provides interactive playgrounds for learning Awk, Sed, and Grep through a web browser using WebAssembly. Built in 2022, the tool is designed for developers and students who want to practice and experiment with these command-line text processing tools without installing them locally. The playgrounds offer a hands-on environment where users can write and test code directly in their browser, making these traditionally difficult Unix utilities more accessible to learners.

    Inspired by Compiler Explorer and other playground/fiddle websites like jsfiddle, db-fiddle, Go playground, and Rust playground, I thought it would be cool to have a playground for nearly any program so I've been working on Program Explorer: a playground for running programs from containers. I am inspired by these playgrounds because they are great educational tools for quickly experimenting and as communication tools by sharing shortlinks that reproduce bugs for instance. I would love for every open source project that publishes a container to get their own playground for free. I'm…

    A WebAssembly runtime embedded in Godot game engine projects. Interact with Wasm modules from GDScript. Accessing Wasm modules via GDScript provides the following benefits. - Sandboxed environment allows safely loading zero-trust mods/extensions to a project. - Single target means that Wasm modules can be built from any language e.g. Rust, Go, AssemblyScript and the single binary can be run on all platforms. - Fast execution compared to GDScript allows for offloading compute-heavy operations or running bots/mods/etc. at high FPS. This might be useful for loading mods, bot AI,…

  • Pipes puzzle (a.k.a. Net) on a hexagonal grid▲537

    Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…
