    Turbo C++

    Turbo C++

    Turbo C++ for Latest Edition of Windows

    TurboCPP is a repository that presents a version of the classic Turbo C++ IDE made compatible with modern Windows editions (Windows 8, 10, 11). Essentially, it revives a legacy development environment that many students or enthusiasts still prefer for simplicity or nostalgia, packaged for current systems. The repository includes installer or distribution artifacts, compatibility wrappers, and sometimes tweaks to make it work under modern OS constraints. It allows users to run and compile old Turbo C++ programs without needing legacy virtual machines or DOS emulators. While it does not match modern compilers in standards compliance, optimization, or language features, its attraction lies in compatibility with educational or legacy codebases. The project targets hobbyists or learners who want to revisit old C++ assignments or retro programming without abandoning newer system environments.

    Arduino IDE

    Arduino IDE

    Arduino IDE library

    This repository contains the source code of the Arduino IDE 2.x, which is currently in the beta stage. The Arduino IDE 2.x is a major rewrite, sharing no code with the IDE 1.x. It is based on the Theia IDE framework and built with Electron. The backend operations such as compilation and uploading are offloaded to an arduino-cli instance running in daemon mode. This new IDE was developed with the goal of preserving the same interface and user experience of the previous major version in order to provide a frictionless upgrade. If you need assistance, see the Help Center and browse the forum. If you think you found a vulnerability or other security-related bug in this project, please read our security policy and report the bug to our Security Team. The builds are generated every day at 03:00 GMT from the main branch and should be considered unstable.

    VSCodium

    VSCodium

    binary releases of VS Code without MS branding/telemetry/licensing

    Microsoft’s vscode source code is open source (MIT-licensed), but the product available for download (Visual Studio Code) is licensed under this not-FLOSS license and contains telemetry/tracking. The VSCodium project exists so that you don’t have to download+build from source. This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled. If you want to build from source yourself, head over to Microsoft’s vscode repo and follow their instructions. VSCodium exists to make it easier to get the latest version of MIT-licensed VSCode. Please note that some Visual Studio Code extensions have licenses that restrict their use to the official Visual Studio Code builds and therefore do not work with VSCodium.
