About
The place to collaborate on an open-source implementation of the Java platform, standard edition, and related projects. Download and install the latest open-source JDK. Oracle’s free, GPL-licensed, production-ready OpenJDK JDK 21 binaries for Linux, macOS, and Windows are available, Oracle’s commercially-licensed JDK 21 binaries, based on the same code, are available as well. Browse the code on the web, clone a repository to make a local copy, and contribute a patch to fix a bug, enhance an existing component, or define a new feature. OpenJDK provides source code that developers can use to build their binaries. Consequently, users are responsible for compiling the code and generating the Java runtime tailored to their specific platform. The JDK is a complex software project. Building it requires a certain amount of technical expertise, a fair number of dependencies on external software, and reasonably powerful hardware.

About
RunMat (by Dystr) is a fast, free, open-source alternative for running MATLAB code.
Users can run their existing .m files with complete MATLAB language grammar and core semantics. No license fees, no lock-in. 300+ built-in functions supported.
RunMat is built with a modern Rust runtime featuring a tiered execution model: an interpreter (Ignition) for instant 5ms startup and a JIT compiler (Turbine/Cranelift) for hot paths. GPU acceleration is automatic via a fusion engine that detects elementwise operation chains and dispatches them as optimized GPU kernels across NVIDIA, AMD, Apple Silicon, and Intel GPUs through Metal, DirectX 12, Vulkan, and WebGPU. Up to 131x faster than NumPy and 7x faster than PyTorch on dense numerical workloads.
Runs everywhere: CLI, NPM package, Homebrew, Jupyter kernel, or instantly in the browser via WebAssembly + WebGPU. Single portable binary. MIT licensed.
