Top 7 C Gpl Projects

  1. reactos

    A free Windows-compatible Operating System

    Project mention: Microsoft Needs Windows Lite | news.ycombinator.com | 2026-06-29

    There is already a "Windows Lite", and it's called ReactOS [0].

    Except, the last thing we need is for Microsoft to own / embrace-extend-exterminate this. It's best that it's kept as an independent project, enabling developers to target the Windows API if they feel like it, while ensuring that they only target the Wine-compatible parts of it, which then enables their software to also run seamlessly on other platforms at no extra effort, and without requiring either the users or the devs to have to lock themselves into this ungodly telemetry-spying-ads-AI-.NET mess that the article talks about.

    Microsoft, on the other hand, has zero to gain from making a Windows Lite variant themselves given their lifeline is exactly this telemetry-spying-ads-AI-.NET ecosystem; and they have zero to gain from absorbing ReactOS or similar projects, other than in order to eliminate them.

    Project mention: Rusefi – GPL internal combustion engine ECU | news.ycombinator.com | 2026-07-15

    Would this work on a generator with a catalytic converter?

    Looks like https://rusefi.com/ lists the features.

    Re: STM32 but for real-time audio in Rust and RTOS / RTIC; from yesterday: https://news.ycombinator.com/item?id=48910657

    The other day re: controlling the rear wheels of a truck like motorcycle trailer tied into the CAN bus: TODO

    oxirs has CAN bus support: oxirs-canbus. oxirs-tauri is a desktop UI with CAN bus support.

    There are Open IP cores for RISC-V for many things.

    Is this already modeled with TLA+?

    Model this with TLA+, critically compare the spec with the implementation, revise, and run it?
