    Vratix API Module Library

    Vratix API Module Library

    Easy to use Open Source modules that implement common API logic

    We created this library of reusable API modules to simplify API development because we were wasting too much time setting up basic functionality and researching the latest backend best practices. We wanted a repository of high-quality API modules we can reuse, copy and paste into our projects and have a working backend in seconds. Currently, the modules work for Express.js, however, we’re actively working to extend compatibility with other backend languages and popular Node.js frameworks. We would be more than happy for you to contribute and help us achieve this faster.

    ArkOS

    ArkOS

    Another rockchip Operating System

    Another rockchip Operating System. This OS came about from an initial fork of The Retro Arena to support a roms folder on a NTFS partition so that the management of roms could be done by simply putting you SD card into an appropriate card reader on a Windows 10 computer. Through various upgrades and tweaks overtime, it has diverged significantly from TheRA and it's time to rebrand this distro. With suggestions provided by community members, ArkOS was chosen.

    Numba CUDA Target

    Numba CUDA Target

    The CUDA target for Numba

    Numba CUDA Target is NVIDIA’s maintained CUDA backend for the Numba JIT compiler, enabling developers to write GPU-accelerated code directly in Python. It allows users to define CUDA kernels using Python syntax, which are then compiled into efficient GPU code at runtime using LLVM-based toolchains. This approach significantly lowers the barrier to entry for GPU programming by eliminating the need to write CUDA C++ while still delivering high performance.

    Kamon Telemetry

    Kamon Telemetry

    Distributed Tracing, Metrics and Context Propagation for applications

    ...With Kamon Telemetry you can collect metrics, propagate context across threads and services, and get distributed traces automatically. The best way to get started is by following our installation guides and taking it from there. Have fun with Kamon. Monitor your backend applications, fix performance issues, and get alerted when problems happen. All without being a monitoring expert. Everybody starts monitoring with logs because they are there by default. Just connect to your server and start tailing. But logs have a hard time showing you the overall response times for your application, or whether certain calls to the database are happening in sequence or parallel (among a million other things).

GQL supports multiple transports to communicate with the backend. Each transport can necessitate specific dependencies. If you only need one transport you might want to install only the dependency needed for your transport, instead of using the “all” extra dependency as described above, which installs everything.
