    Arduino

    Arduino

    Open-source electronics platform

    Arduino is an open-source physical computing platform based on a simple I/O board and a development environment that implements the Processing/Wiring language. Arduino can be used to develop stand-alone interactive objects or can be connected to software on your computer (e.g. Flash, Processing and MaxMSP). The boards can be assembled by hand or purchased preassembled. Arduino is a popular tool for IoT product development as well as one of the most successful tools for STEM/STEAM education. Hundreds of thousands of designers, engineers, students, developers and makers around the world are using Arduino to innovate in music, games, toys, smart homes, farming, autonomous vehicles, and more. Arduino is the first widespread Open Source Hardware project and was set up to build a community that could help spread the use of the tool and benefit from contributions from hundreds of people who helped debug the code, write examples, create tutorials, etc.

    FernFlower

    FernFlower

    Decompiler from Java bytecode to Java, used in IntelliJ IDEA

    Fernflower is an open-source Java decompiler originally developed by JetBrains that takes compiled Java bytecode and reconstructs readable source code, helping developers understand, debug, and recover lost Java code from .class files. It works by analyzing the structure of bytecode and inferring higher-level constructs like loops, conditionals, generics, and exception handling to produce Java source that is as close as possible to what a human would have written, making it useful for both reverse engineering and educational purposes. Fernflower is integrated into popular Java IDEs and tools where decompilation is needed, and its robust analysis handles a wide range of language features introduced across multiple Java versions. Because it outputs clean, structured, and often compilable code, developers use it for auditing binaries, exploring third-party libraries without source, and recovering parts of legacy systems where source was lost or unavailable.

    Copybara

    Copybara

    Copybara: A tool for transforming and moving code between repositories

    Copybara is an open source code transformation and migration tool developed by Google for synchronizing and managing source code across multiple repositories. It allows developers to transform, filter, and move code between repositories while maintaining a consistent source of truth. Copybara is particularly useful in workflows where projects maintain both confidential (internal) and public (open source) repositories, enabling controlled synchronization and contribution management between them. The tool supports advanced transformations—such as file relocation, content replacement, and metadata adjustments—defined declaratively in configuration files. It operates in a stateless manner, storing synchronization state within commit metadata to ensure reproducibility and collaboration among multiple users. Copybara currently supports Git repositories (with experimental Mercurial support) and can be integrated with CI/CD systems or run manually.
