   A minimal working Rust / SDL2 / WASM browser game▲82

   "Game" is a stretch, but I put together this repo containing a pure Rust app which uses SDL2 and compiles to WASM (and can be run in a browser). Older resources were a bit out of date and a bit too verbose for my purposes, so here's a minimal working example.

    G# –> a new dotnet language like Go/Swift/Kotlin with C# interop▲9

    I started working on this back in 2019, mostly as a design idea. Over the last month I made a big push to make it 100% usable and replace C# in all my personal projects. I now feel it's solid enough to gather feedback from other developers. If you take it for a spin, I hope you enjoy it and send your thoughts!

    ADK-Rust▲6

    Hey everyone! I'm excited to share ADK-Rust - a production-ready implementation of Google's Agent Development Kit in Rust. Why Rust? After working extensively with adk-python in developing an ai agent factory at zavora.ai, I wanted to bring the same powerful agent development patterns to the Rust ecosystem, targeting use cases where: Performance is critical - Rust's zero-cost abstractions and memory safety Deployment size matters - Single binary with no runtime dependencies Systems-level integration - Embedded systems, edge computing, IoT Concurrency at scale - Rust's async/await with…
